Abstract

The utility model provides a shunting type vibration seeding apparatus. The utility model is characterized in that a seed plate of the vibration seeding apparatus is additionally connected with shunting plates by ranks according to the requirements of seeding quantity; shunting holes are arranged on the shunting plates. During vibration seeding, the utility model only discharge required seed quantity of the seeding quantity, and superfluous seeds are shunted and recovered at the shunting holes so as to realize stable, uniform and reliable seeding.

Description

Shunting vibration seeding unit

The utility model relates to agricultural machinery seeding apparatus field, is a kind of oscillatory type dispenser.Existing oscillatory type seeding unit is to utilize specific vibration source to force main seed plate vibration, makes the seed that comes from seed-box, forms seed flow, pushes forward, discharges, and realizes sowing.The size of seeding quantity mainly realizes that by the size of control vibratory output vibratory output is big, amount of seed metering big (seeding quantity is big), on the contrary then opposite.That the oscillatory type seeding unit has is simple in structure, cost is low, the seeding quantity adjustable range is wide, advantages such as injuring-free seed, but when little seeding quantity operation (when particularly sowing paddy rice), because vibratory output is little, the seed translational speed is slow, occurs seeding cutout and clogging easily, thereby make the stability, uniformity of seeding and the reliability decrease of work, influence seeding quality.Therefore existing oscillatory type seeding unit only is applicable to the seeding operation of big amount of seed metering, has limited its scope of application, has had a strong impact on the application and the popularization of oscillatory type seeding unit.

The purpose of this utility model provides a kind of shunting vibration seeding unit, when it not only can guarantee big seeding quantity, stable, evenly, seeding reliably, and when little seeding quantity, cutout does not appear, clogging guarantees seeding quality.

The purpose of this utility model is achieved in that presses the seeding quantity size on the V-type slot type master seed plate of vibration seeding unit, respectively the shunting disk of adjunction different size class.V-type groove both sides on the shunting disk of different size class are drilled with the tap hole of different sizes or diverse location.When seeding quantity was big, tap hole was less or tap hole is bigger apart from the height of V-type bottom land on the shunting disk of institute's adjunction.Seeding quantity hour, the tap hole on the used shunting disk is big or tap hole is less apart from the height of V-type bottom land.How many decisions of the seed shunt volume that the size of tap hole requires during by seeding.The requirement shunt volume is many, and then tap hole is big.The requirement shunt volume is few, and then tap hole is little.The shape of tap hole is determined by shape of the seed, can be rectangle, and garden hole shape and other shape, purpose are to make seed flow when tap hole, and the shunting of being shaken easily avoids seed by tap hole card, stifled, the influence shunting.Allow the vibration seeding unit during work under bigger vibratory output effect, discharge bigger seed flow,, prevent that cutout or clogging from appearring in seed flow to overcome the frictional force between seed flow and the seed plate.If the seeding quantity that requires is big, the shunting disk that main seed plate adjunction tap hole is less or the position is higher, when seed flow during through this shunting disk, this dish only allows the seed flow of regulation seeding quantity to pass through, flow into discharging tube and fall into field realization sowing, unnecessary seed is then fallen into the concentrator recycle of reclaiming seed by the shunting of the tap hole on the shunting disk and uses.If the seeding quantity that requires hour, the big or lower shunting disk in position of adjunction tap hole then on the main seed plate, this dish only allows the less seed flow of regulation seeding quantity to pass through, other unnecessary seed is then divided to flow into to collect by tap hole plants recycle use in the device, thereby make the vibration seeding unit when more good momentum, under the state of big amount of seed metering, realize the precision drilling operation of different seeding quantitys or less seeding quantity.

The utility model because only need be on original equipment the shunting disk of adjunction different size class, so structure is simple especially.Simultaneously because the seeding quantity size no longer relies on the vibratory output size to control, and mainly lean on the size or the position of the tap hole on the shunting disk just to limit, therefore when little seeding quantity operation, the vibration seeding unit also can adopt big vibratory output seeding, not only effectively prevent seed flow cutout or stifled match phenomenon, and can eliminate the error that each row seed distributing groove causes owing to reasons such as manufacturing or the rough property of seed self preferably, thus improve the uniformity of each row amount of seed metering of seeding unit, guarantee the uniformity of sowing.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is an external form schematic diagram of the present utility model

Fig. 2 be among Fig. 1 A to cutaway view

Describe the course of work of the present utility model in detail below in conjunction with Fig. 1, Fig. 2.

As shown in Figure 1, shunting is vibrated seeding unit by seed-box (1), the main seed plate (2) of V-type slot type, and shunting disk (3), the tap hole on the shunting disk (4), spring leaf (5), vibration source (6), collection kind of a device (7), discharging tube parts such as (8) are formed.During work, starting vibration source (6) forces main seed plate (2) vibration, because main seed plate (2) is to be supported by spring leaf (5), thereby produces vibration.Under the vibration effect, the main seed plate (2) that falls into the V-type slot type from the seed of seed-box (1) vibrate propelling movement as Fig. 1 (direction of arrow); Move forward the formation seed flow, the tap hole (4) that moves to shunting disk (3) when seed because vibration effect and part seed are built on stilts, makes built on stilts seed shake when locating, and shunting falls into collection kind of a device (7) and reclaims the recycle use.And be in the V-type groove, being lower than the following remaining seed flow of tap hole (4) continues to move forward, and falls into discharging tube (8) at last and enters the field, realizes sowing.The size that the size of the tap hole (4) on the shunting disk (3) or position just determine shunting action has also just determined the size of seeding quantity.Under identical vibration effect, seed flow on the main seed plate (2) is also identical, but when the tap hole (4) on the shunting disk (3) hangs down than big or position, the grain weight that is fallen into concentrator (7) by shunting is more, allow by the seed flow of shunting disk (3) less, thereby realize little seeding quantity sowing, on the contrary then opposite, also can realize the sowing of big seeding quantity.

The utility model all has excellent adaptability to different crop seeds and different seeding quantitys.It is good, simple in structure to have seeding quality, reliable operation, characteristics such as easy to adjust.
