【０００１】
【発明が属する技術分野】
本発明は、略水平に設置される機筐の供給部から排出部へ米等の穀粒を搬送する搬送コンベアを設けた横送り搬送装置に関するものであり、特に、搬送コンベアの搬送体について工夫したものである。
【０００２】
【従来の技術】
従来公知の、特公平２−３６４８４号公報には、搬送方向に長く形成した機筐に環状ベルトを設け、環状ベルトに所定間隔を置いて搬送体を複数設け、搬送体の下面と底板との間に僅かな間隙を設けた構成について記載されている。
【０００３】
【発明が解決しようとする課題】
前記公知例の搬送コンベアは、環状ベルトに所定間隔を置いて搬送体を複数設けているから、取付が面倒であるという課題がある。
また、ベルトを支持案内しているため、ベルトに対して搬送体が振動し、図１５のように搬送体ｃの下面と底板ｂとの間に僅かな間隙とは言え、１ｃｍ程もある間隙を持たせて移動させているから、残留穀粒を排出搬送するためには、前記公報には記載されていないが、底板に常時摺接する弾性部材のスクレーパー（前記公報には従来例として底板に非接触のスクレーパーコンベアが記載されているが、本来スクレーパーは底板に常時摺接して残留穀粒を搬送するものとして説明する）を必要とし、このスクレーパーが破損すると、破損物が異物として搬送物に混入する。
特に、最近では、精米後の米は、「無洗米」と称して、そのまま調理する傾向にあるから、搬送物内に異物が混入すると、穀粒の価値を著しく減じ、スクレーパーをを有する搬送装置の搬送経路には相当高価な選別機を設けいるのが、現状である。
したがって、スクレーパーを不要とする搬送装置であれば、相当高価な選別機も不要になるが、単に、スクレーパーを不要とすると、機筐内に穀粒が残留し、この残留穀粒は黴が生えたり、鼠が出たりと、不都合この上ないので、誰もがスクレーパー不要を希望しつつ実現できなかったのである。
また、前記公知例では、底板上面と搬送体の下縁との間の隙間が穀粒より相当に大きいから、底板上に残る穀粒と搬送体により搬送作用を受ける穀粒とが上下に二層存在することになり、この上下二層の境めの穀粒同士が擦れあって損傷する。
また、搬送体の幅は、穀粒流路の幅より狭いので（図１６）、搬送体の搬送力の非作用域が生じ、この部分で穀粒同士が擦れあって損傷する現象を発生させるでけでなく、穀粒流路が広いから搬送体の搬送力は穀粒を側方に逃がすように作用し、確実に搬送できず、残留することがある。
本願は、搬送体の下縁を底板に接触させない範囲で間隙を可及的に小さくし、スクレーパーを不要にして、破損物が異物として搬送物に混入するのを未然に防止すると共に、搬送体の取付けを工夫することにより、一層、搬送効率を向上させ、また、メンテナンス作業を容易にしたものである。
【０００４】
【発明の目的】
スクレーパー不要の搬送コンベアの提供、残留穀粒の排出の確実化、穀粒の損傷の抑制および防止、振動、騒音の発生の減少および抑制、耐久性の向上、メンテナンス作業の容易化、低コスト化。
【０００５】
【課題を解決するための手段】
本発明は、機筐１の供給部２と排出部６の間に無端チェン１３に所定間隔を置いて搬送体１２を複数設けて構成した搬送コンベア７を設け、前記各搬送体１２は、前記機筐１内の穀粒流路１８の少なくとも底板１６上面に対して穀粒より小なる隙間を有して支持機構Ｘにより直接案内支持された状態で移動するようにし、前記支持機構Ｘは、前記穀粒流路１８を、平滑な底板１６と、該底板１６の左右側の略垂直の起立板１７と、該起立板１７の上端より上方に至るに従い側方に広がるように設けた傾斜支持板部２０により形成し、前記各搬送体１２には前記左右の傾斜支持板部２０の上面に摺接移動する左右の傾斜摺接面２１を有して構成し、前記各搬送体１２は、前記無端チェン１３を構成する前後方向の左右一対の両側リンク２５に交差方向に突出するように、分割して左右の両側リンク２５の夫々と一体的に合成樹脂により形成し、前記分割した両側リンク２５の下縁より下方に位置する搬送体下縁２４を、前記起立板１７の内面に対して穀粒より小なる隙間を有して幅方向一杯に位置させると共に、左右の分割搬送体１２の間には、穀粒より小さい隙間３０を設けた穀粒用横送り搬送装置としたものである。
本発明は、機筐１の供給部２と排出部６の間に無端チェン１３に所定間隔を置いて搬送体１２を複数設けて構成した搬送コンベア７を設け、前記各搬送体１２は、前記機筐１内の穀粒流路１８の少なくとも底板１６上面に対して穀粒より小なる隙間を有して支持機構Ｘにより直接案内支持された状態で移動するようにし、前記支持機構Ｘは、前記穀粒流路１８を、平滑な底板１６と、該底板１６の左右側の略垂直の起立板１７と、該起立板１７の上端より上方に至るに従い側方に広がるように設けた傾斜支持板部２０により形成し、前記各搬送体１２には、前記左右の傾斜支持板部２０の上面に摺接移動する左右の傾斜摺接面２１を有して構成し、前記各搬送体１２は、複数の無端チェン１３の前後方向の左右一対の両側リンク２５のうちの所定の両側リンク２５の夫々の両側に、進行方向に対して交差方向に突出させ、且つ、左右に分割して両側リンク２５と一体的に合成樹脂により形成し、前記両側リンク２５の下縁より下方に位置する搬送体下縁２４を、前記穀粒流路１８の起立板１７の内面に対して穀粒より小なる隙間を有して幅方向一杯に位置させると共に、左右の分割搬送体１２の間には、穀粒より小さい隙間３０を設けた穀粒用横送り搬送装置としたものである。
本発明は、前記無端チェン１３は、前記各両側リンク２５を、係止軸部材２６と止着部材３２により着脱分解可能に連結して形成した穀粒用横送り搬送装置としたものである。
本発明は、前記支持機構Ｘは、穀粒流路１８を、平滑な底板１６と、該底板１６の左右側の略垂直の起立板１７と、該起立板１７の上端より上方に至るに従い側方に広がるように設けた傾斜支持板部２０により形成し、前記各搬送体１２には前記左右の傾斜支持板部２０の上面に常時摺接する左右の傾斜摺接面２１を夫々設け、該傾斜摺接面２１の下方に前記穀粒流路１８の底板１６及び起立板１７の内面に対して穀粒より小なる隙間を有して移動する下部側縁２２及び搬送体下縁２４を夫々形成して構成した穀粒用横送り搬送装置としたものである。
【０００６】
【実施例】
本発明の一実施例を図により説明すると、１は横送り搬送装置の機筐であり、搬送方向に長く形成する。該機筐１の一端側上方位置に供給部２を設け、他端には落口５を有する排出部６を設ける。
この場合、供給部２は１個または複数を中間部に設けてもよく、同様に他端の排出部６以外にも中間部に１個または複数の排出部６を設けてもよく、中間の排出部６には落口５を開閉させるシャッター（図示省略）を設ける。
前記供給部２の供給口（図示省略）と他端の排出部６の間の機筐１内には、搬送コンベア７を設ける。説明の都合上搬送コンベア７の搬送方向を前後方向とすると、搬送コンベア７は、前記供給部２の後部の機筐１内に従動歯車８を従動軸９により軸装する。前記終端の排出部６より手前側の機筐１内に駆動歯車１０を駆動軸１１により軸装する。この従動歯車８と駆動歯車１０の間に複数の搬送体１２を所定間隔を置いて設けた移動部材Ｙを構成する無端チェン１３を掛け回す。
【０００７】
この場合、無端チェン１３は、供給部２の手前側の従動歯車８と終端落口５の先側の駆動歯車１０との間に掛け回して、搬送体１２を供給部２の手前側（搬送方向上手側）より終端落口５の先側まで移動させて穀粒を搬送する。
しかして、前記機筐１内には、底板１６と、該底板１６の左右側の略垂直に起立する起立板１７を有する穀粒流路１８を設け、前記各搬送体１２は該穀粒流路１８の内面に対して穀粒より小なる隙間を有して支持機構Ｘにより横振れや片寄り走行することなく直接案内支持された状態で移動するように構成する。
即ち、従来は、搬送体１２ではなく無端チェン１３等の移動部材Ｙを案内するガイドを設け、直接搬送体１２を案内する支持機構Ｘを設けていないので、横振れや片寄っての移動を考慮して、搬送体１２と穀粒流路１８（機筐１）の間に隙間を設けて、搬送体１２が機筐１の内面に当たる騒音発生を防止していたが、そのため、前記隙間から搬送体１２により搬送されない穀粒が残され、残留物となっていた。
【０００８】
この場合、縦方向の底板１６との隙間は、底板１６に常時摺接する弾性部材のスクレーパーを設けていたが、常時摺接するため損傷が激しく千切れて搬送物に混入することがある。
そこで、搬送体１２は、支持機構Ｘにより底板１６との間に穀粒より小なる隙間（０〜１ｍｍ）を有して移動させる構成にすると、穀粒流路１８内の残留穀粒を発生させずに搬送する。
また、従来は図１５のように、側板ａを底板ｂに対して傾斜させ、搬送体ｃと側板ａの接触を防止しているが、搬送体ｃの進行方向に対する交差方向に穀粒流路ｄが広く形成されていると、搬送体ｃの搬送力は穀粒ｅに図１６のように側方に逃がすように作用し、確実に排出させられないか、あるいは、相当に時間が掛かり、どの位排出用の運転時間を設定すればよいかの判断が非常に困難である。
【０００９】
そこで、搬送体１２は、支持機構Ｘにより起立板１７との間に穀粒より小なる隙間（０〜１ｍｍ）を有して移動させる構成にすると、一層、穀粒流路１８内の残留穀粒を発生させずに搬送する。
しかして、支持機構Ｘは、穀粒流路１８を、底板１６と、該底板１６の左右側の略垂直の起立板１７と、該起立板１７の上端より上方に至るに従い側方に広がるように設けた傾斜支持板部２０により形成し、一方、前記各搬送体１２は、合成樹脂の板部材により、前記左右の傾斜支持板部２０の上面に常時摺接する左右の傾斜摺接面２１を有して構成する。
即ち、左右の傾斜摺接面２１は搬送体１２の自重で機筐１の傾斜支持板部２０に摺接した状態で移動することにより、常時左右の傾斜支持板部２０の中央に位置するように搬送体１２を案内し、移動中の搬送体１２が左右に振れるのを防止する。
したがって、搬送体１２は、傾斜摺接面２１の下方の下部側縁２２を支持機構Ｘにより前記傾斜摺接面２１が傾斜支持板部２０の上面に摺接した状態で前記起立板１７より穀粒より小なる隙間（０〜１ｍｍ）を有して移動するように容易に設定できる。
【００１０】
また、左右の傾斜摺接面２１が機筐１の傾斜支持板部２０に摺接して支持されて、これ以上下がる余地がない状態で移動するので、搬送体１２の搬送体下縁２４は前記傾斜摺接面２１が傾斜支持板部２０の上面に摺接した状態で前記底板１６の上面より穀粒より小なる隙間（０〜１ｍｍ）を有して移動するように容易に設定できる。
これにより、各搬送体１２にの何れかに別途所謂スクレーパを取付けるのを不要にする。
換言すると、機筐１内に形成した穀粒流路１８の上部に、穀粒流路１８の移動方向に対する交差方向両外側に至るに従い高くなる傾斜支持板部２０を、移動方向に亘って設け、穀粒流路１８を移動する搬送体１２は、傾斜支持板部２０上を摺接移動する傾斜摺接面２１を設けることにより、穀粒流路１８の起立板１７と左右の側縁下部側縁２２との間に穀粒（米粒）より小さい隙間を有して、底板１６上を摺接移動するように構成するのである。
【００１１】
したがって、起立板１７の深さおよび底板１６の幅は任意であり、この起立板１７の深さおよび底板１６の幅に応じて搬送体１２が中央を移動するように傾斜支持板部２０および傾斜摺接面２１の傾斜角度を設定すればよい。
しかして、前記無端チェン１３は、前後方向の両側リンク２５を係止軸部材２６により着脱自在に連結して無端状に形成し、前記両側リンク２５のうち所定のものの左右両側には進行方向に対して交差方向に突出するように搬送体１２を、一体的に合成樹脂により形成すると、製造が容易になって、好適である。
この場合、前記搬送体１２は、無端チェン１３の前後方向の左右一対の両側リンク２５の夫々に側方に突出させ、搬送体１２の搬送体下縁２４は両側リンク２５の下縁より下方に位置させ、底板１６の幅方向一杯に一体状に形成してもよいが、搬送体１２は左右に分割し、一対の両側リンク２５に夫々一体的に形成すると、取付（組立）が容易になり、好適である。
この場合、分割した左右の搬送体１２の間には、穀粒（米粒）より小さい隙間３０を設けて取付ける。左右の両側リンク２５はその間に係止軸部材２６を挿通するローラ３１を挟んで位置させ、係止軸部材２６の端部を割りピン等の止着具３２により着脱自在に取付ける。３３は座金である。
【００１２】
したがって、左右の搬送体１２の一方が破損しても容易に交換でき、好適である。
また、各両側リンク２５を係止軸部材２６により連結して無端状に形成しているから、特別な専用の工具を使用することなく、止着具３２を外すと、多数ある両側リンク２５のどれでも外せる。
したがって、無端チェン１３のメンテナンス作業を容易にし、無端チェン１３の機筐１に対する設定長さ調節も容易になって、好適である。
また、搬送体下縁２４は、搬送体１２の進行方向の前側に至るに従い高くなる下縁面取り傾斜面３４に形成すると、搬送体下縁２４が底板１６に仮に接触しても、搬送体１２の板厚面全体による面接触ではなく、下縁面取り傾斜面３４の最も低い部分が搬送体下縁２４となって側面視線接触ですむので、異音の発生を最小限に抑制する。なお、搬送体１２は正逆（前後）何れの方向にも移動させて穀粒を供給部２と排出部６とに移動させるように構成することがあるが（例えば中央に供給部２を設け、両端に排出部６を設け、あるいは、供給部２と排出部６とを交互に配置して各供給部２と排出部６との間を搬送する）、この場合は、搬送体１２の前後両方向に下縁面取り傾斜面３４を設ける。
【００１３】
また、無端チェン１３を構成する両側リンク２５および搬送体１２の上面の夫々は、断面を三角形状のの頂点を挟んで次第に低くなるように傾斜させた穀粒落下面３５に形成すると、両側リンク２５および搬送体１２の上面に穀粒が載って残留物となるのを防止できて、好適である。３６は上行きの無端チェン１３を支持する支受ローラであり、所定間隔を置いて複数設ける。３７は下行きの無端チェン１３の浮きを防止する浮き防止体であり、所定間隔を置いて複数設ける。
しかして、前記排出部６の落口５には、シャッタ４０を設け、該シャッタ４０は平板により形成し、シャッタ４０の一端にはシャッタ４０を移動させるシリンダ等のアクチュエータ４１を設け、シャッタ４０の他端は底板１６の開口部４２を閉塞する盲板のみにより形成して構成し、前記シャッタ４０の上方には、前記支持機構Ｘを設ける。４３はシャッタ４０を取付けるフレーム、４４はエア吹出口である。
【００１４】
即ち、搬送体１２は、前記のように傾斜摺接面２１を有して形成し、シャッタ４０の上方には前記底板１６の開口部４２を臨ませ、開口部４２の上方に前記穀粒流路１８を形成する起立板１７と傾斜支持板部２０を設けることにより、シャッタ４０の上方には、前記支持機構Ｘを設けている。
しかして、前記搬送体１２は前記供給部２に対して搬送方向上手側より該供給部２の下方を通過するように、前記無端チェン１３を掛け回す駆動歯車または受動歯車を配置し、該駆動歯車または受動歯車の下方の前記底板１６には残留穀粒排出口４５及び該残留穀粒排出口４５を開閉させる開閉シャッタ４６を設ける。
４７は受動歯車８の斜め後側下方に設けた案内板、４８は穀粒誘導板である。
【００１５】
【作用】
次ぎに作用を述べる。
モーターに通電すると、駆動歯車１０が回転し、駆動歯車１０は無端チェン１３を回転させて搬送体１２を供給部２から排出部６へ移動させる。
機筐１内には、底板１６と、該底板１６の左右側の略垂直の起立板１７を有する穀粒流路１８を設け、各搬送体１２は支持機構Ｘにより直接案内支持された状態で移動するように構成しているから、各搬送体１２は全て支持機構Ｘにより横振れや片寄り走行することなく穀粒流路１８の中央を移動し、穀粒流路１８の内面のうち特に底板１６と搬送体１２の搬送体下縁２４との間の隙間を穀粒より小さく設定しても、搬送体下縁２４を底板１６に接触させることなく移動させる。
したがって、搬送体１２が機筐１の内面に当たる騒音を発生させることなく、底板１６上面と搬送体１２の搬送体下縁２４との間の隙間を穀粒より小さく可及的に狭くでき、搬送体１２による搬送残りがなく、残留穀粒を発生させない。
【００１６】
このことは、底板１６に常時摺接する弾性部材のスクレーパーを不要にし、このスクレーパーの破損物が異物として搬送物に混入することを、防止する。
また、底板１６上面と搬送体１２の搬送体下縁２４との間の隙間が穀粒より大きいと、底板１６上に残る穀粒と搬送体１２により搬送作用を受ける穀粒とが上下に二層存在することになり、この上下二層の境めの穀粒同士が擦れあって損傷することになるが、底板１６上面と搬送体１２の搬送体下縁２４との間の隙間は穀粒より小なる隙間のため、搬送体１２は上下に分布する穀粒全体を一緒に搬送することになって、前記穀粒同士の擦れ合いによる損傷を防止する。
【００１７】
しかして、搬送体１２は、支持機構Ｘにより案内支持されて移動するので、底板１６の左右側の起立板１７を、略垂直に設けつつ、搬送体１２の下部側縁２２と起立板１７の間の隙間を穀粒より小なる隙間に設定できる。
したがって、搬送体１２の搬送力は、穀粒流路１８の幅方向の全ての穀粒に及び、幅方向においても、搬送体１２によって搬送されている穀粒と搬送残りの穀粒との間における穀粒同士が擦れあって損傷する現象の発生を防止する。
即ち、図１５のように搬送体ｃの進行方向に対する交差方向に穀粒流路ｄが広く形成されていると、搬送体ｃの搬送力は側部の穀粒ｅに側方に逃がすように作用し、確実に搬送できず、ここに穀粒ｅ同士が擦れあって損傷する現象を発生させるが、本願では、これを防止する。
しかして、支持機構Ｘは、穀粒流路１８を、平滑な底板１６と、該底板１６の左右側の略垂直の起立板１７と、該起立板１７の上端より上方に至るに従い側方に広がるように設けた傾斜支持板部２０により形成し、一方、各搬送体１２は、合成樹脂の板部材により、前記左右の傾斜支持板部２０の上面に常時摺接する左右の傾斜摺接面２１を有して構成しているから、左右の傾斜摺接面２１は搬送体１２の自重で機筐１の傾斜支持板部２０に摺接した状態でこれ以上下がる余地がないまま移動することになり、搬送体１２の搬送体下縁２４は底板１６の上面より穀粒より小なる隙間を有して移動する。
【００１８】
したがって、穀粒流路１８の起立板１７の上方に傾斜支持板部２０を設けることと、搬送体１２に傾斜支持板部２０に合わせた傾斜摺接面２１を設ければ、支持機構Ｘを構成することができ、頗る簡単な構成にでき、コストを低くできる。また、左右の傾斜摺接面２１が傾斜支持板部２０に摺接した状態で移動することにより、常時左右の傾斜支持板部２０の中央に位置するように搬送体１２を案内しているから、仮に、搬送体１２に左右の一方に振れるような力が発生しても、横振れさせる力は、傾斜摺接面２１が傾斜支持板部２０に当たった反力となって、搬送体１２を他方に戻すように作用し、搬送体１２は常時左右の穀粒流路１８の中央に位置して移動するように案内支持される。
したがって、支持機構Ｘは、上下方向を案内する構成でありながら、幅方向（左右方向）も案内支持する作用を奏するので、搬送体１２の下部側縁２２と起立板１７の間の隙間も穀粒より小なる隙間に設定でき、一層、合理的で、コストを低くする構成となる。
【００１９】
このように、搬送体１２の下部側縁２２と起立板１７の間の隙間を穀粒より小に設定すると、起立板１７の間の穀粒は、起立板１７により側方に退避できない状態で搬送体１２により搬送され、搬送効率を向上させ、また、穀粒流路１８内の残留搬送物を発生させず、短時間に全て排出させる。
この場合、傾斜支持板部２０は、搬送量が減少したときには、穀粒を起立板１７の間の穀粒流路１８内に誘導する作用を奏するが、傾斜支持板部２０の上方を傾斜摺接面２１より上方の搬送体１２が移動すること、傾斜支持板部２０の下方は左右の起立板１７間の穀粒は側方に退避させずに搬送しうることから、傾斜支持板部２０は起立板１７の間の穀粒流路１８内に誘導する作用を奏しながら搬送効率を低下させない。
それゆえ、搬送体１２の上面より上方に穀粒があっても、傾斜支持板部２０に搬送体１２の傾斜摺接面２１を摺接させているので、傾斜支持板部２０の上方の穀粒には傾斜摺接面２１よりも上方の搬送体１２の部分が作用すること、および、この上方の穀粒はその下方を搬送ベルトのように移動する穀粒に載ったまま移動すること、等の作用が相俟って、上下一体状に搬送されるので、搬送量の多少に関わらず、常に所定の搬送効率を確保しつつ、上下間における穀粒の損傷発生も最小限にする。
なお、傾斜支持板部２０および傾斜摺接面２１の左右幅は、夫々、搬送体１２の案内に必要な最小面積にすると、一層、上下間における搬送むら発生を防止できて、搬送効率を向上させられて、好適である。
しかして、搬送体１２は、無端チェン１３の前後方向の両側リンク２５のうち所定のものの左右両側に、進行方向に対して交差方向に突出するように設け、搬送体１２と両側リンク２５は一体的に合成樹脂により形成しているから、製造が容易であり、金属製のものに比し軽量化でき移動中の振動を減少させ、騒音発生を最小限にして、好適である。
【００２０】
この場合、搬送体１２は、無端チェン１３の前後方向の左右一対の両側リンク２５の夫々に側方に突出させ、両側リンク２５の下縁より下方に位置する搬送体１２の搬送体下縁２４を、底板１６の幅方向一杯に位置させると共に、搬送体１２は左右に分割し、一対の両側リンク２５に夫々一体的に形成しているから、両側リンク２５と搬送体１２は夫々板厚の製造精度があれば、組立精度の確保を充分にでき、製造および取付（組立）が容易になり、好適である。
また、分割した左右の搬送体１２の夫々の搬送体下縁２４の間には、穀粒（米粒）より小さい隙間３０を有して両側リンク２５に取付けるように構成しているから、両側リンク２５の板厚と、ローラ３１の長さとが正確に製造されていれば、両側リンク２５の幅及び搬送体１２の幅寸法の組立精度は充分に確保され、一体状に形成した場合に比し、容易に精度を確保でき、好適である。
即ち、穀粒より小さい隙間３０が、ばらつきを吸収して、搬送体１２の左右幅の精度を向上させ、ひいては搬送体１２の下部側縁２２と起立板１７の間の隙間の設定精度も向上させる。
【００２１】
また、搬送体１２は、左右に分割すると、左右の一方の搬送体１２が破損しても容易に交換でき、好適である。
この場合、無端チェン１３は、各両側リンク２５を係止軸部材２６により連結して無端状に形成し、各両側リンク２５の連結は係止軸部材２６を挿通して着脱自在の止着具３２により止着しているから、特別な専用の工具を使用することなく、止着具３２を外すと、多数ある両側リンク２５のどれでも外せる。
したがって、無端チェン１３のメンテナンス作業を容易にし、無端チェン１３の機筐１に対する設定長さ調節も容易になって、好適である。
しかして、搬送体１２の搬送体下縁２４は、搬送体１２の進行方向の前側に至るに従い高くなる下縁面取り傾斜面３４に形成しているから、仮に、搬送体下縁２４が底板１６上面に接触しても、搬送体１２の板厚面（下面）全体による面接触ではなく、下縁面取り傾斜面３４の最も低い部分である搬送体下縁２４のみが側面視線接触でするので、異音の発生を最小限に抑制できる。
【００２２】
また、搬送体１２の前後両方向に下縁面取り傾斜面３４を設けると、搬送体１２を正逆（前後）何れの方向にも移動させることができ、供給部２と排出部６との配置の自由度を向上させ、汎用性を向上させられる。
しかして、無端チェン１３を構成する両側リンク２５および搬送体１２の上面の夫々は、断面を三角形状の角形状に形成して穀粒落下面３５に形成してあるから、両側リンク２５および搬送体１２の上面に穀粒が載って残留物となるのを防止できて、好適である。
しかして、前記排出部６の落口５には、シャッタ４０を設け、該シャッタ４０は平板により形成し、シャッタ４０の一端にはシャッタ４０を移動させるシリンダ等のアクチュエータ４１を設け、シャッタ４０の他端は底板１６の開口部４２を閉塞する盲板のみにより形成して構成し、前記シャッタ４０の上方には、前記支持機構Ｘを設けているから、搬送体１２の搬送体下縁２４がシャッタ４０と接触するのを防止できる。
【００２３】
また、底板１６の開口部４２に別途案内部材を設けることが不要となるので、コストを低くする。
即ち、従来、底板の開口部に搬送体の下縁を下方から支持する案内部材を設けているため、この案内部材上に穀粒が残るという課題と、案内部材はシャッタの盲板の閉塞部分よりも他端側に形成していたため、案内部材を設けた分シャッタの長さが長くなって、装置全体が大型になっていたが、これを解決する。
しかして、前記搬送体１２は前記供給部２に対して搬送方向上手側より該供給部２の下方を通過するように、前記無端チェン１３を掛け回す駆動歯車または受動歯車を配置構成し、該駆動歯車または受動歯車の下方の前記底板１６には残留穀粒排出口４５及び該残留穀粒排出口４５を開閉させる開閉シャッタ４６を設けているから、開閉シャッタ４６を開けると、供給部２より搬送方向上手側の駆動歯車または受動歯車の下方の底板１６上に残留している穀粒を取り出せる。
即ち、無端チェン１３を掛け回す駆動歯車または受動歯車は、供給部２より搬送方向上手側に位置していても、供給部２の下方を通る無端チェン１３上に載った穀粒が運ばれて、落ちることがあること、無端チェン１３を掛け回す駆動歯車または受動歯車の後側下方には案内板４７を設けていても、各両側リンク２５が所定長さを有して側面視完全な円弧移動ではなく多角移動（運動）なので、搬送体１２との隙間が大きくなること、特に、案内板４７および底板１６に摺接するスクレーパを設けていないことから、供給部２より搬送方向上手側に穀粒が残留することがあるが、この残留している穀粒を取り出せる。
したがって、案内板４７および底板１６に摺接するスクレーパを省略したことのデメリットを回避しつつ、スクレーパーの損傷破損物が搬送物に混入するという不具合発生を未然に防止する。
また、案内板４７を複雑な円弧形状に形成することなく、残留穀粒排出口４５へ穀粒を案内誘導しうる傾斜板により形成すればよく、この点でも、コストを低くする。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a transverse feeder provided with a transport conveyor that transports grains such as rice from a supply unit to a discharge unit of a machine housing that is installed substantially horizontally, and in particular, devises a transport body of the transport conveyor. It was done.
[0002]
[Prior art]
Conventionally, Japanese Patent Publication No. 2-36484 discloses a case in which an annular belt is provided in a case formed long in the transport direction, a plurality of transport bodies are provided at predetermined intervals on the annular belt, and a lower surface of the transport body and a bottom plate are connected. A configuration with a slight gap between them is described.
[0003]
[Problems to be solved by the invention]
The known conveyor has a plurality of conveyors provided at predetermined intervals on the annular belt, and thus has a problem that the mounting is troublesome.
Further, since the belt is supported and guided, the carrier vibrates with respect to the belt, and as shown in FIG. 15, the gap between the lower surface of the carrier c and the bottom plate b is about 1 cm, though it is a small gap. In order to discharge and transport the remaining kernels, a scraper of an elastic member that is always in sliding contact with the bottom plate (in the above-mentioned publication, a conventional example of a bottom plate is disclosed in the above publication). Although a non-contact scraper conveyor is described, it is necessary to explain that the scraper is always in sliding contact with the bottom plate and transports the remaining kernels). Mixed.
In particular, recently, rice after polishing is called “non-washed rice” and tends to be cooked as it is. Therefore, if foreign matter is mixed in the conveyed material, the value of the grain is significantly reduced, and the conveying device having a scraper is used. At present, a considerably expensive sorting machine is provided in the transport path of the present invention.
Therefore, if the transfer device does not require a scraper, a considerably expensive sorting machine is not required, but if the scraper is not required, kernels remain in the machine housing, and the residual kernels grow mold. There were no inconveniences, such as the presence of a mouse or a mouse, so everyone could not realize it, hoping to eliminate the need for a scraper.
Further, in the known example, since the gap between the upper surface of the bottom plate and the lower edge of the carrier is considerably larger than the grain, the kernel remaining on the bottom plate and the grain subjected to the carrying action by the carrier are vertically separated. There is a layer, and the grains at the boundary between the upper and lower layers rub against each other and are damaged.
Further, since the width of the carrier is smaller than the width of the grain flow path (FIG. 16), a non-working area of the carrier force of the carrier is generated, and a phenomenon occurs in which grains are rubbed against each other and damaged. In addition, since the grain flow path is wide, the carrying force of the carrier acts to release the grain to the side, and the grain cannot be transported reliably and may remain.
The present application is to minimize the gap as long as the lower edge of the carrier is not in contact with the bottom plate, eliminate the need for a scraper, prevent broken objects from entering into the carrier as foreign matter, and By contriving the mounting of, the transfer efficiency is further improved and the maintenance work is facilitated.
[0004]
[Object of the invention]
Provision of a conveyor that does not require a scraper, reliable discharge of residual grains, suppression and prevention of damage to grains, reduction and suppression of vibration and noise, improvement of durability, ease of maintenance work, and cost reduction .

[0006]
【Example】
An embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 denotes a machine housing of a lateral feeder, which is formed longer in the transport direction. A supply section 2 is provided at an upper position on one end side of the casing 1, and a discharge section 6 having a dropout 5 is provided at the other end.
In this case, one or more of the supply units 2 may be provided in the intermediate unit, and similarly, one or more discharge units 6 may be provided in the intermediate unit other than the discharge unit 6 at the other end. The discharge unit 6 is provided with a shutter (not shown) for opening and closing the opening 5.
A transport conveyor 7 is provided in the casing 1 between a supply port (not shown) of the supply unit 2 and a discharge unit 6 at the other end. For convenience of description, if the transport direction of the transport conveyor 7 is the front-back direction, the transport conveyor 7 has a driven gear 8 mounted on a driven shaft 9 in the machine housing 1 at the rear of the supply unit 2. A drive gear 10 is axially mounted on a drive shaft 11 in the machine case 1 on the front side of the discharge section 6 at the end. An endless chain 13 that constitutes a moving member Y in which a plurality of carriers 12 are provided at predetermined intervals between the driven gear 8 and the driving gear 10 is wound around.
[0007]
In this case, the endless chain 13 is looped between the driven gear 8 on the front side of the supply unit 2 and the drive gear 10 on the front side of the terminal drop 5 to transport the transport body 12 to the front side of the supply unit 2 (transportation). The grain is conveyed by moving from the upper side in the direction) to the end side of the terminal drop 5.
Thus, a grain flow path 18 having a bottom plate 16 and an upright plate 17 that stands substantially vertically on the left and right sides of the bottom plate 16 is provided in the machine housing 1. It has a clearance smaller than the grain with respect to the inner surface of the path 18 and is configured to move in a state of being directly guided and supported by the support mechanism X without running laterally or running sideways.
That is, conventionally, a guide for guiding the moving member Y such as the endless chain 13 instead of the carrier 12 is provided, and a support mechanism X for directly guiding the carrier 12 is not provided. A gap is provided between the carrier 12 and the grain flow path 18 (machine 1) to prevent the carrier 12 from hitting the inner surface of the machine 1, so that the carrier 12 is conveyed from the gap. Grains that were not transported by the body 12 were left as residues.
[0008]
In this case, the gap between the vertical bottom plate 16 and the bottom plate 16 is provided with a scraper made of an elastic member that is always in sliding contact with the bottom plate 16.
Therefore, if the transport mechanism 12 is configured to be moved by the support mechanism X with a gap (0 to 1 mm) smaller than the grain between the bottom plate 16 and the transport mechanism 12, residual grains in the grain channel 18 are generated. Convey without doing.
Conventionally, as shown in FIG. 15, the side plate a is inclined with respect to the bottom plate b to prevent the contact between the carrier c and the side plate a. When d is formed widely, the conveying force of the conveying body c acts on the grain e so as to escape to the side as shown in FIG. 16, and it cannot be discharged reliably, or it takes considerable time, It is very difficult to determine how long the operation time for discharge should be set.
[0009]
Therefore, when the transporting body 12 is configured to be moved by the support mechanism X with a gap (0 to 1 mm) smaller than the grain between the upright plate 17 and the supporting mechanism X, the remaining grain in the grain channel 18 is further increased. Convey without generating particles.
Thus, the support mechanism X extends the grain flow path 18 to the side as the bottom plate 16, the substantially vertical upright plate 17 on the left and right sides of the bottom plate 16, and the upper end of the upright plate 17. Are formed by the inclined support plate portions 20 provided on the left and right sides. On the other hand, each of the transport bodies 12 has a left and right inclined sliding contact surface 21 which is always in sliding contact with the upper surface of the left and right inclined support plate portions 20 by a synthetic resin plate member. It has and is constituted.
That is, the right and left inclined sliding contact surfaces 21 are always positioned at the center of the left and right inclined supporting plate portions 20 by moving in a state of sliding contact with the inclined supporting plate portions 20 of the machine housing 1 by the weight of the transport body 12. To prevent the moving carrier 12 from swaying left and right.
Accordingly, the carrier 12 is moved from the upright plate 17 by the support mechanism X so that the lower side edge 22 below the inclined sliding contact surface 21 is brought into sliding contact with the upper surface of the inclined supporting plate portion 20 by the support mechanism X. It can be easily set to move with a gap (0 to 1 mm) smaller than the grain.
[0010]
Further, since the left and right inclined sliding contact surfaces 21 are slidably supported by the inclined support plate portion 20 of the machine casing 1 and move without any room for further lowering, the lower edge 24 of the transport body 12 is In a state where the inclined sliding contact surface 21 is in sliding contact with the upper surface of the inclined support plate portion 20, it can be easily set so as to move with a gap (0 to 1 mm) smaller than the grain than the upper surface of the bottom plate 16.
This eliminates the need to separately attach a so-called scraper to any of the transport bodies 12.
In other words, on the upper part of the grain flow path 18 formed in the casing 1, the inclined support plate portion 20 which becomes higher as it reaches both outer sides in the direction intersecting the moving direction of the grain flow path 18 is provided in the moving direction. The transporting body 12 moving in the grain flow path 18 is provided with an inclined sliding contact surface 21 that slides and moves on the inclined support plate portion 20, so that the upright plate 17 of the grain flow path 18 and lower left and right side edges are provided. With a gap smaller than a grain (rice grain) between the side edge 22 and the side edge 22, a sliding movement is performed on the bottom plate 16.
[0011]
Therefore, the depth of the upright plate 17 and the width of the bottom plate 16 are arbitrary, and the inclined support plate portion 20 and the inclined support plate portion 20 are moved so that the transport body 12 moves in the center according to the depth of the upright plate 17 and the width of the bottom plate 16. What is necessary is just to set the inclination angle of the sliding contact surface 21.
Thus, the endless chain 13 is formed in an endless shape by removably connecting both side links 25 in the front-rear direction by a locking shaft member 26, and the left and right sides of a predetermined one of the two side links 25 in the traveling direction. It is preferable that the carrier 12 be integrally formed of synthetic resin so as to protrude in the cross direction.
In this case, the transport body 12 is made to project laterally to each of a pair of left and right side links 25 in the front-rear direction of the endless chain 13, and the transport body lower edge 24 of the transport body 12 is lower than the lower edge of the both side links 25. It may be positioned and formed integrally with the entire width of the bottom plate 16 in an integral manner. However, if the transport body 12 is divided into left and right sides and integrally formed on a pair of both side links 25, mounting (assembly) becomes easy. Is preferred.
In this case, a gap 30 smaller than a grain (rice grain) is provided between the divided right and left transport bodies 12 and attached. The left and right side links 25 are positioned so as to sandwich the roller 31 through which the locking shaft member 26 is inserted, and the end of the locking shaft member 26 is detachably attached by a fastening tool 32 such as a split pin. 33 is a washer.
[0012]
Therefore, even if one of the left and right carriers 12 is damaged, it can be easily replaced, which is preferable.
Further, since both side links 25 are connected to each other by the locking shaft member 26 to form an endless shape, if the fastening tool 32 is removed without using a special tool, a large number of side links 25 can be formed. You can remove any.
Therefore, the maintenance work of the endless chain 13 is facilitated, and the adjustment of the set length of the endless chain 13 with respect to the machine casing 1 is also facilitated, which is preferable.
Further, if the lower edge 24 of the transport body is formed on the lower edge chamfered inclined surface 34 that becomes higher as it reaches the front side in the traveling direction of the transport body 12, even if the lower edge 24 of the transport body temporarily contacts the bottom plate 16, , The lowest part of the lower edge chamfering inclined surface 34 becomes the lower edge 24 of the transport body and only needs to be in line-of-sight contact, so that generation of abnormal noise is minimized. In some cases, the transport body 12 may be configured to move in either the forward or backward (front-back) direction to move the grains to the supply unit 2 and the discharge unit 6 (for example, the supply unit 2 is provided at the center). The discharge units 6 are provided at both ends, or the supply units 2 and the discharge units 6 are alternately arranged to convey between the supply units 2 and the discharge units 6). A lower edge chamfered inclined surface 34 is provided in both directions.
[0013]
Further, when the both-side links 25 constituting the endless chain 13 and the upper surface of the transport body 12 are formed on a grain falling surface 35 whose cross section is inclined so as to be gradually lower with a triangular vertex therebetween, the both-side links are formed. This is preferable because it is possible to prevent kernels from remaining on the upper surface of the carrier 25 and the carrier 12. Reference numeral 36 denotes a support roller for supporting the upward endless chain 13, and a plurality of support rollers are provided at predetermined intervals. Reference numeral 37 denotes an anti-floating body for preventing the downward endless chain 13 from floating, and a plurality of anti-floating bodies are provided at predetermined intervals.
Thus, a shutter 40 is provided at the outlet 5 of the discharge section 6, the shutter 40 is formed of a flat plate, and an actuator 41 such as a cylinder for moving the shutter 40 is provided at one end of the shutter 40. The other end is formed of only a blind plate that closes the opening 42 of the bottom plate 16, and the support mechanism X is provided above the shutter 40. 43 is a frame on which the shutter 40 is mounted, and 44 is an air outlet.
[0014]
That is, the transport body 12 is formed to have the inclined sliding contact surface 21 as described above, the opening 42 of the bottom plate 16 is exposed above the shutter 40, and the grain flow is located above the opening 42. The support mechanism X is provided above the shutter 40 by providing the upright plate 17 and the inclined support plate portion 20 that form the path 18.
Thus, the driving body or the passive gear which loops around the endless chain 13 is disposed so that the transporting body 12 passes below the supplying section 2 from the upstream side in the transporting direction with respect to the supplying section 2. The bottom plate 16 below the gear or passive gear is provided with a residual grain discharge port 45 and an open / close shutter 46 for opening and closing the residual grain discharge port 45.
Reference numeral 47 denotes a guide plate provided diagonally behind and below the passive gear 8, and reference numeral 48 denotes a grain guiding plate.
[0015]
[Action]
Next, the operation will be described.
When the motor is energized, the drive gear 10 rotates, and the drive gear 10 rotates the endless chain 13 to move the carrier 12 from the supply unit 2 to the discharge unit 6.
A grain channel 18 having a bottom plate 16 and a substantially vertical upright plate 17 on the left and right sides of the bottom plate 16 is provided in the machine housing 1, and each carrier 12 is directly guided and supported by a support mechanism X. Since each of the transporting bodies 12 is configured to move, all of the transporting bodies 12 move in the center of the grain flow path 18 without lateral deflection or offset running by the support mechanism X. Even if the gap between the bottom plate 16 and the lower edge 24 of the transporter 12 is set smaller than the grain, the lower edge 24 of the transporter is moved without contacting the bottom plate 16.
Accordingly, the gap between the upper surface of the bottom plate 16 and the lower edge 24 of the transport body 12 can be made as small as possible and smaller than the grain without causing the transport body 12 to hit the inner surface of the machine housing 1. There is no residual transport by the body 12 and no residual kernel is generated.
[0016]
This obviates the need for a scraper of an elastic member that is always in sliding contact with the bottom plate 16 and prevents the broken material of the scraper from being mixed as foreign matter into the conveyed material.
Further, if the gap between the upper surface of the bottom plate 16 and the lower edge 24 of the carrier of the carrier 12 is larger than the grain, the kernel remaining on the bottom plate 16 and the grain subjected to the carrying action by the carrier 12 are vertically separated. There is a layer, and the grains at the boundary between the upper and lower layers rub against each other and are damaged. However, the gap between the upper surface of the bottom plate 16 and the lower edge 24 of the transporter 12 is the grain. Because of the smaller gap, the carrier 12 conveys the whole grain distributed vertically, thereby preventing damage due to friction between the grains.
[0017]
Thus, since the transport body 12 moves while being guided and supported by the support mechanism X, the right and left upright plates 17 of the bottom plate 16 are provided substantially vertically, and the lower side edge 22 of the transport body 12 and the upright plate 17 are supported. The gap between them can be set to be smaller than the grain.
Therefore, the transport force of the transport body 12 extends to all the grains in the width direction of the grain flow path 18, and also in the width direction, between the grains transported by the transport body 12 and the remaining transported grains. In this case, the occurrence of a phenomenon in which grains are rubbed against each other and damaged is prevented.
That is, as shown in FIG. 15, when the grain flow path d is formed widely in the direction intersecting with the traveling direction of the transport body c, the transport force of the transport body c is released to the side of the grain e on the side. The grains e cannot be transported reliably and cause a phenomenon in which the grains e are rubbed against each other to be damaged. However, this phenomenon is prevented in the present invention.
Thus, the support mechanism X moves the grain flow path 18 toward the smooth bottom plate 16, the substantially vertical upright plate 17 on the left and right sides of the bottom plate 16, and the upper side from the upper end of the upright plate 17. On the other hand, each transport body 12 is formed of a synthetic resin plate member, and the right and left inclined sliding contact surfaces 21 constantly slidingly contact the upper surfaces of the left and right inclined support plate portions 20. Since the left and right inclined sliding contact surfaces 21 are in sliding contact with the inclined support plate portion 20 of the machine housing 1 by the weight of the transport body 12, the left and right inclined sliding contact surfaces 21 move without any room for further lowering. That is, the lower edge 24 of the transport body of the transport body 12 moves with a gap smaller than the grain from the upper surface of the bottom plate 16.
[0018]
Therefore, if the inclined support plate portion 20 is provided above the standing plate 17 of the grain flow path 18 and the inclined sliding contact surface 21 corresponding to the inclined support plate portion 20 is provided on the transport body 12, the support mechanism X can be formed. It can be configured to have a very simple configuration and cost can be reduced. In addition, since the left and right inclined sliding contact surfaces 21 move while sliding on the inclined support plate portion 20, the transport body 12 is always guided to be positioned at the center of the left and right inclined support plate portions 20. Even if a force that swings to the left or right occurs in the transport body 12, the force to cause the lateral shake is a reaction force of the inclined sliding contact surface 21 hitting the inclined support plate portion 20, and the transport body 12 Is returned to the other side, and the carrier 12 is always guided and supported so as to move at the center of the left and right grain channels 18.
Accordingly, since the support mechanism X is configured to guide in the up-down direction, it also has the function of guiding and supporting in the width direction (left-right direction), so that the gap between the lower side edge 22 of the transport body 12 and the upright plate 17 is also reduced. The gap can be set to be smaller than the size of the grain, which is more rational and lowers the cost.
[0019]
As described above, when the gap between the lower side edge 22 of the transport body 12 and the upright plate 17 is set smaller than the grain, the grain between the upright plates 17 cannot be retreated to the side by the upright plate 17. It is transported by the transport body 12 to improve the transport efficiency and to discharge all the transported material in the grain flow path 18 in a short time without generating any residual transported material.
In this case, when the transport amount is reduced, the inclined support plate portion 20 has an effect of guiding the grains into the grain flow path 18 between the upright plates 17. Since the transport body 12 above the contact surface 21 moves, and the grains between the right and left upright plates 17 can be transported without retreating to the side below the inclined support plate portion 20, the inclined support plate portion 20 Does not lower the transport efficiency while exhibiting the action of guiding into the grain passage 18 between the upright plates 17.
Therefore, even if there is a grain above the upper surface of the carrier 12, since the inclined sliding contact surface 21 of the carrier 12 is slid on the inclined support plate portion 20, the grain above the inclined support plate portion 20. That the portion of the transport body 12 above the inclined sliding contact surface 21 acts on the grain, and that the grain above this moves below the grain on a grain that moves like a transport belt; In combination with the above-mentioned operations, the material is conveyed vertically and integrally, so that regardless of the amount of conveyance, a predetermined conveyance efficiency is always ensured, and the occurrence of damage to the grain between the upper and lower parts is minimized.
When the left and right widths of the inclined support plate portion 20 and the inclined sliding contact surface 21 are respectively set to the minimum area required for guiding the transport body 12, uneven transport between the upper and lower portions can be further prevented, and the transport efficiency is improved. It is preferred.
Thus, the transport body 12 is provided on both left and right sides of a predetermined one of the two side links 25 in the front-rear direction of the endless chain 13 so as to protrude in a direction crossing the traveling direction. Since it is made of a synthetic resin, it is easy to manufacture, is lighter than a metal one, reduces vibration during movement, and minimizes noise generation.
[0020]
In this case, the transport body 12 is protruded laterally from each of a pair of left and right side links 25 in the front-rear direction of the endless chain 13, and the transport body lower edge 24 of the transport body 12 located below the lower edge of the both side links 25. Is positioned over the bottom plate 16 in the width direction, and the transport body 12 is divided into left and right and integrally formed on a pair of both-side links 25, so that the both-side links 25 and the transport body 12 have a plate thickness of respectively. If the manufacturing accuracy is high, the assembling accuracy can be sufficiently ensured, and the manufacturing and mounting (assembly) become easy, which is preferable.
In addition, since each of the divided left and right carriers 12 has a gap 30 smaller than a grain (rice grain) between the lower edges 24 of the respective carriers, the two carriers are attached to the both-side links 25. If the thickness of the roller 25 and the length of the roller 31 are accurately manufactured, the assembly accuracy of the width of the two-sided link 25 and the width of the carrier 12 is sufficiently ensured, as compared with the case where they are integrally formed. It is preferable because accuracy can be easily secured.
That is, the gap 30 smaller than the grain absorbs the variation, and improves the accuracy of the right and left width of the carrier 12, and thus also improves the setting accuracy of the gap between the lower side edge 22 of the carrier 12 and the upright plate 17. Let it.
[0021]
Further, if the transport body 12 is divided into right and left, even if one of the right and left transport bodies 12 is damaged, it can be easily replaced, which is preferable.
In this case, the endless chain 13 is formed in an endless shape by connecting each side link 25 by a locking shaft member 26, and the connection of each side link 25 is performed by inserting and removing the locking shaft member 26 to be detachable. Since the fastening is performed by the fixing member 32, any of the numerous side links 25 can be removed by removing the fastening member 32 without using a special tool.
Therefore, the maintenance work of the endless chain 13 is facilitated, and the adjustment of the set length of the endless chain 13 with respect to the machine casing 1 is also facilitated, which is preferable.
Since the lower edge 24 of the transport body 12 is formed on the lower edge chamfered inclined surface 34 that becomes higher as it reaches the front side in the traveling direction of the transport body 12, the lower edge 24 of the transport body is temporarily Even if the upper surface is contacted, the lower edge 24 of the lower end 24 of the lower edge chamfering inclined surface 34 is not in contact with the entire plate thickness surface (lower surface) of the transporter 12 but is in side view contact. Generation of abnormal noise can be suppressed to a minimum.
[0022]
In addition, if the lower edge chamfering inclined surface 34 is provided in both front and rear directions of the transport body 12, the transport body 12 can be moved in both forward and backward (front and rear) directions, and the arrangement of the supply unit 2 and the discharge unit 6 can be adjusted. The degree of freedom can be improved, and versatility can be improved.
The two-sided link 25 constituting the endless chain 13 and the upper surface of the carrier 12 are each formed on the grain falling surface 35 by forming a triangular section in cross section. This is preferable because it is possible to prevent the kernels from remaining on the upper surface of the body 12 and remaining.
Thus, a shutter 40 is provided at the outlet 5 of the discharge section 6, the shutter 40 is formed of a flat plate, and an actuator 41 such as a cylinder for moving the shutter 40 is provided at one end of the shutter 40. The other end is formed only by a blind plate that closes the opening 42 of the bottom plate 16, and the support mechanism X is provided above the shutter 40. The contact with the shutter 40 can be prevented.
[0023]
In addition, since it is not necessary to provide a separate guide member in the opening 42 of the bottom plate 16, the cost is reduced.
That is, conventionally, since a guide member for supporting the lower edge of the carrier from below is provided in the opening of the bottom plate, there is a problem that kernels remain on the guide member, and the guide member is a closed portion of the blind plate of the shutter. Since the shutter is formed on the other end side, the length of the shutter is increased by an amount corresponding to the provision of the guide member, and the entire apparatus is increased in size.
Thus, the carrier 12 is provided with a drive gear or a passive gear that loops around the endless chain 13 so as to pass below the supply unit 2 from the upstream side in the conveyance direction with respect to the supply unit 2. The bottom plate 16 below the driving gear or the passive gear is provided with a residual grain discharge port 45 and an opening / closing shutter 46 for opening and closing the residual grain discharge port 45. Grains remaining on the bottom plate 16 below the drive gear or passive gear on the upstream side in the transport direction can be taken out.
That is, even if the drive gear or the passive gear that wraps around the endless chain 13 is located on the upstream side in the transport direction from the supply unit 2, the grain loaded on the endless chain 13 passing below the supply unit 2 is carried. Even if a guide plate 47 is provided on the lower rear side of the drive gear or the passive gear around which the endless chain 13 is hung, each side link 25 has a predetermined length and a complete circular arc in side view. Since the movement is not a movement but a polygonal movement (movement), the gap with the carrier 12 is large, and in particular, since no scraper is provided for sliding contact with the guide plate 47 and the bottom plate 16, the grain is located on the upstream side in the transport direction from the supply unit 2. Grains may remain, but the remaining grains can be removed.
Therefore, it is possible to avoid the disadvantage of omitting the scraper that is in sliding contact with the guide plate 47 and the bottom plate 16, and to prevent the occurrence of a problem that the damaged and damaged material of the scraper is mixed into the conveyed object.
Further, the guide plate 47 may be formed by an inclined plate capable of guiding the kernel to the residual kernel discharge port 45 without forming the arc into a complicated arc shape. In this regard, the cost is also reduced.
[0024]
