By the way, when the landed grain is introduced into the silo, or the required amount is taken out of the silo and supplied, or the storage and management of the company is necessary, the grain is stored in another storage room or storage place. In the case of moving, a long duct is disposed in the building, grains are put into the duct, and the whole grains are pushed and transported toward the discharge port of the duct to move and transport them.
[0003]
FIGS. 16 to 20 show a conventional cereal conveying apparatus on a conveying path. In the figures, for example, an endless conveyor that moves around the entire length in a rectangular conveying duct 10 having a cross section having a length of about 50 meters. The chain 12 is arranged, a plurality of blades 14 are fixed at required intervals in the longitudinal direction so as to protrude from the conveyor chain 12 in the lateral direction, and through the chute 15 through the opening formed on the upper surface of the transfer duct 10. Then, the grains are introduced into the duct, and the conveyor chain is driven to rotate so that the whole grains are pushed toward the discharge port 16 by the blades 14 located at the lower moving portion side. As shown in FIGS. 18 to 20, the upper surface of the bottom wall in the transfer duct 10 and the middle position in the height direction in the same duct are closer to the upper position, that is, the vertically separated position in the duct is located at the center position in the width direction. An endless conveyor in which a plurality of splicers 20 are cascaded in a chain and pivotally connected so as to straddle the rail member 18 from above. The chain 12 is placed, and the conveyor chain 12 travels and moves in the transport duct 10 while being guided by the rail member 18.
[0004]
By the way, in the conventional grain conveying apparatus as described above, as shown in FIG. 19 and FIG. 20, in the wing plate 14 extending laterally from the conveyor chain, the bottom wall 10a of the duct and the lower end side 14a of the wing plate, the wing plate A gap S is formed between the inner side 14b of the conveyor 14 and the conveyer chain 12 or between the overhanging end 14c of the slat 14 and the side wall 10b, and there is a problem that it is difficult to transport the grains to be pushed without remaining. For this reason, when the cereals to be transported in the duct are, for example, barley to soybeans or edible cereals and cereals for feed materials, etc., are transported in different types, there is a possibility that different kinds of cereals may be mixed.
[0005]
[Problems to be solved by the invention]
On the other hand, for example, a push plate member having a side closer to the bottom wall and the side wall of the duct in a shape enlarged from the blade plate so as to be perpendicular to the conveying direction of the duct may be bolted to the blade plate. Conceivable. However, it is difficult to travel between the push plate member and the duct bottom wall 10a while maintaining their close contact with each other over the entire length of the duct, and it is difficult particularly when there is a bent or up-down portion of the duct. Yes, and therefore undesired undesired portions tend to occur. In addition, when fixed to the chain conveyor, the chain conveyor itself runs while always applying a load to the lower end side of the push plate member, so that the lower end portion is worn out early, and the push plate member and the bottom wall of the duct are in contact with each other. An air gap is generated between them. In addition, the replacement cycle when worn out is fast, the replacement work at a plurality of places is complicated, and the work time is required. Furthermore, in the case of a conveying duct extending over a long section of, for example, 50 meters or 100 meters, the laterally projecting end of the push plate member must be set so as not to be in close contact with the side wall 10b so as not to damage the side wall 10b of the duct. A gap is also formed between the protruding end of the pressing plate member and the side wall 10b, and unpressed portions are generated. Further, with this push plate member, there is a problem that it is difficult to shield the gap between the inner side 14b of the blade plate 14 and the rail member 18 or the bottom wall 10a in the transport direction. In particular, in the case of cereals genetically manipulated using recent genetic recombination techniques, the mixing of different types of cereals becomes a serious problem, and strict control is required even in the stage of transport in ducts.

In this embodiment, for example, soybean, barley, etc. This is an example in which the present invention is applied to a grain pushing device (hereinafter, referred to as a “pushing device” P) installed in a grain conveying path.
[0014]
In the figure, a pushing device P is provided in a transfer duct 10 having a rectangular cross section as a closed transfer path, and the transfer duct 10 is formed of, for example, a hollow transfer duct having a length of about 50 meters and a bottom wall 10a. , The left and right side walls 10b, and the top wall 10c, the periphery of which is closed. As shown in FIG. 16, large chain pulleys 22 are provided at both ends of the transfer duct 10, and one of them is connected to a drive motor (not shown) to be driven to rotate. The chain pulley 22 is provided with an endless conveyor chain 12 which is tuned in a circular shape, and performs a circular movement in the direction of the arrow, for example, by the rotation of the pulley 22. An opening 26 that is continuous with the shooter 15 is formed on the upper surface near the right end side of the transport duct 10, and grains are sequentially fed from the upper grain storage unit 28 for each designated lot and dropped into the hollow interior of the transport duct 10. Then, by driving the conveyor chain to rotate, the grains fed in are swept and fed through the cleaning member 30 supported by the blades 14 projecting in the lateral direction of the chain.
[0015]
The conveyor chain 12 is configured by alternately connecting splicers 20 having different lateral widths on the short side side with pins 32 in a row in a row, and has a substantially full length of the duct at a central portion in the width direction within the transport duct 10. The pins 32 are arranged in such a manner as to be placed in the cross direction on the upper surface of the rail member 18 protrudingly fixed at a vertical position in the transport duct 10 so as to circulate in the transport duct 10 so as to be guided by the rail member 18. To run. The rail member 18 is provided on both side walls at an intermediate height position of the transport duct, and a support plate 19 is fixed thereto. The rail member 18 is projected and fixed on the support plate 19.
[0016]
One characteristic of the present invention is that a rail member 18 provided in the longitudinal direction at the center of the width of the bottom wall of the conveying duct, a conveyor chain 12 running while being guided by the rail member, That is to say, there is provided a wing plate 14 provided to protrude in the direction, and a cleaning member 30 attached to the wing plate and having a flexible and flexible contact surface. In FIGS. 1, 2, 3, and 7, the cleaning member 30 has a contact surface C that at least substantially adheres to the bottom wall 10a and the side wall 10b of the transport duct, and the contact surface C has flexibility and flexibility. It is formed from a material having the same. More specifically, the contact surface C of the cleaning member 30 is located at the lower end of the rail member 18 and the entire width of the bottom wall from the bottom wall 10a of the transfer duct to the corner of the bottom wall 10a and the side wall 10b, and further in the lateral direction from the blade plate 14. And formed on the continuous side wall portion which abuts on the side wall 10b and rises from the corner 10d, and these portions are brought into close contact with the cleaning member on both sides of the duct, so that the inside of the duct is shielded and inserted.

And a thick felt-like cloth body 38 fixed to the winding attachment section. As shown in FIGS. 6 and 7, the wrapping portion 36 is formed by winding the wing plate 14, which is wound around the wing plate 14 extending in the lateral direction so that the wing plate 14 orbits around the wick. In the embodiment, the winding attachment portion 36 is formed of a canvas cloth woven with thick fibers or yarns. Therefore, the winding attachment portion 36 itself has flexibility and flexibility, and has a certain degree of rigidity. Then, one end of the transport duct is abutted on the rail member 18 in the width direction, and the other end of the transport duct is wound so as to be in close contact with the side wall 10b of the duct. Even in this case, for example, the side wall 10b of the metal transfer duct is not damaged or broken during traveling. Further, a felt-like cloth body 38 is fixed to the lower end side of the wrapping mounting portion 36 over the entire width direction. As a result, the lower end side contact surface of the felt-like cloth body 38 is brought into close contact with the entire width direction of the bottom wall 10a of the transfer duct, and both end sides are brought into close contact with the vertical wall of the rail member 18 and the side wall 10b of the transfer duct.

In addition, the contact surface of the felt-like cloth body portion is a flexible and flexible material, so that it can flexibly maintain a close contact state even when the duct is bent or up-down, and can be in contact with the wall surface of the duct. The replacement cycle can be lengthened while maintaining durability without being worn early by contact. Further, since the abrasion is small and the shielding state in the duct at these mounting positions can be secured over the entire surface, the number of cleaning members attached to the blades can be reduced. The contact surface may be formed by, for example, performing a flocking process on the surface of a synthetic resin, cloth, leather, or another material. Alternatively, the entire structure may be integrally formed of the same flexible and flexible material, and this may be wound around the blade plate. In addition, the cleaning member is not necessarily wound and fixed to the blade plate, but may be wound with a string or other thin material, tied and fixed, bolted nut fixed, or any other fixing method. The cleaning member does not have to be configured to be detachable from the blade body, and may be used by being detachably fixed with, for example, bolts and nuts.

The operation is manually performed on the desired blade plate 14 through the opening 26 on the upper surface side of the transfer duct. The winding around the blades is performed from the top wall opening side of the duct so that the end surface of the felt-like fabric body 38 comes into close contact with the bottom wall 10a of the transport duct 10 when the conveyor chain rotates and moves downward. At the time of mounting, as shown in FIG. 8, the mounting portion 36 is wound and mounted so that the felt-like cloth body 38 faces upward. When the conveyor chain 12 rotates and moves down in the transport duct, the contact surface C of the cleaning member shields the bottom wall 10a over the entire length, and the side wall side is also wrapped from the corner by the wrapping mounting portion 36 and the felt-like fabric body 38. The rising portion up to the upper edge is shielded, and in this embodiment, particularly, the narrow gap between the rail member 18 and the conveyor chain 12 is also shielded. The cereal contamination accident can be reliably prevented. The contact surface C is formed of a flexible and flexible material, so that when the portion is pressed against the bottom wall or the side wall, the shape easily changes, and the tip portion reaches every corner to improve adhesion. In addition, the contact area can be widened to reliably prevent unpressed portions.
[0022]
