Description

Technical Field

[0001] The utility model relates to the technical field of corn harvester accessories, and more specifically to a harvesting conduction chain for preventing corn grains from being damaged. Background Art

[0002] Corn harvester is a new type of agricultural machinery that is used to mechanically remove corn ears and harvest corn stalks when the corn is ripe or nearly ripe according to agronomic requirements. It is a new type of agricultural machinery developed for the development of new energy sources and to reduce the labor intensity of farmers. The corn harvesting transmission chain is used to transport corn during the corn harvesting process. However, the straw board set on the harvesting transmission chain may reduce the pushing force during the pushing process due to insufficient material hardness, thereby reducing the conduction stability of the corn. In addition, the excessively fast conduction speed of the harvesting transmission chain will cause the corns to squeeze each other, making it impossible for the straw board to be pushed, which in turn causes blockage and reduces the conduction efficiency.

[0003] For example, announcement number CN206042837U discloses a harvesting conduction chain for preventing damage to corn grains, including a conduction chain and a plurality of straw plates, both ends of the conduction chain are respectively wrapped with transmission sprockets, and the straw plates are evenly distributed on the conduction chain, characterized in that: the straw plates include a fixed chain seat and straw pieces, the bottom surface of the fixed chain seat is fixed to the outside of the chain piece of the conduction chain, the bottom of the straw piece is fixed to the fixed chain seat, and the straw piece is an integral wedge-shaped block structure with elastic or buffering properties.

[0004] It can be seen from the above-mentioned public scheme that the straw blades are made of wear-resistant rubber. Although they can protect the corn, their strength is insufficient. When the corn is harvested at a fast speed, the amount of corn pushed by the straw blades increases, making the straw blades easy to bend and deform, which in turn causes the straw blades to be unable to push the corn for conduction, causing blockage and reducing the conveying stability and efficiency of the harvesting conduction chain.

A sprocket tooth is arranged on the outer side of the conveying sprocket 2, and a tooth hole is arranged on the conductive chain body 1 for easy engagement. At the same time, a conveying shaft is arranged at the center of the conveying sprocket 2, and a driving motor is arranged at one end of the conveying shaft. Its composition structure and working principle are well known to those skilled in the art and will not be described in detail herein. The inner surface of the conductive chain body 1 is engaged with the conveying sprocket 2, and the outer surface of the conductive chain body 1 is fixedly mounted with toggle plates 3 distributed at equal intervals. The number of toggle plates 3 is twelve, and the number can also be set according to the actual length of the conductive chain. The plate 3 is composed of a plate body 31, a protective head 32, a buffer part 33 and a toggle plate fixing seat 34. The protective head 32 and the buffer part 33 are fixedly compounded at both ends of the plate body 31. A symmetrical connecting plate 341 is provided at the bottom of the toggle plate fixing seat 34. A connecting hole 342 is provided on the side of the connecting plate 341. The connecting hole 342 facilitates the connection and fixation of the toggle plate fixing seat 34 with the conductive chain shaft rod. A connecting strip 343 is provided at the top of the toggle plate fixing seat 34. One end of the connecting strip 343 is fixedly connected to one end of the plate body 31. The connecting strips 343 are evenly spaced along the width direction of the plate body 31. The connecting strips 343 are made of corrosion-resistant elastic metal rods. The connecting strips 343 facilitate the bending and resetting of the plate body 31, which can improve the connection stability and support stability of the plate body 31.

[0026] The plate body 31 is made of wear-resistant metal plate, and an arcuate portion 313 is provided on the forward surface of the plate body 31. An upper through hole 311 and a lower through hole 312 are provided on the surface of the plate body 31. The upper through holes 311 and the lower through holes 312 are evenly spaced. The plate body 31 not only has good strength, but also the arcuate portion 313 ensures the conduction stability of corn. The upper through holes 311 and the lower through holes 312 are both strip holes. The inner wall of the upper through hole 311 is fixedly bonded to the inside of the protective head 32, and the inner wall of the lower through hole 312 is fixedly bonded to the inside of the buffer portion 33. The upper through holes 311 and the lower through holes 312 improve the composite firmness with the protective head 32 and the buffer portion 33.

[0027] The cross-sectional shape of the protective head 32 is semicircular, the width of the protective head 32 is greater than the width of the plate body 31, the protective head 32 is made of wear-resistant rubber, the protective head 32 has the function of buffering and protection, and can prevent the corn from sliding out of one end of the plate body 31, the width of the buffer part 33 is greater than the width of the plate body 31, the buffer part 33 is made of wear-resistant rubber, the connecting strip 343 is fixed and compounded inside the buffer part 33, the buffer part 33 is deformed and bent when the pushing resistance of the plate body 31 is too large, so that the plate body 31 will not excessively squeeze the corn.

[0028] When the harvesting conduction chain for preventing corn grain damage is in use, the driving motor drives the conveying sprocket 2 to rotate clockwise, and the conveying sprocket 2 rotates clockwise to drive the conduction chain body 1 to move rightward, and the conduction chain body 1 moves rightward to drive the toggle plate 3 to move rightward, and the toggle plate 3 moves rightward to push the corn to be conducted to the right, and the surface of the corn contacts with the surface of the plate body 31, the buffer part 33 and the protective head 32. When the toggle plate 3 pushes more corn to the right, the corn presses the plate body 31 to the left, so that the buffer part 33 and the connecting strip 343 are bent and deformed, thereby producing The bending elastic force is generated, and when the amount of corn conducted to the right becomes less, the bending elastic force causes the plate body 31 to rebound and reset. The metal plate body 31, the buffer part 33 and the connecting strip 343 can not only increase the toggling strength of the toggling plate 3, but also avoid excessive squeezing of the corn to cause damage, thereby greatly improving the conduction efficiency of the corn. In addition, the protective head 32 and the arc-shaped part 313 of the plate body 31 can not only prevent one end of the toggling plate 3 from squeezing the corn, but also have the function of preventing slipping, thereby greatly improving the transportation stability of the corn.
