Description

Technical Field

[0001] The present invention belongs to agricultural machinery, and mainly relates to a seed cleaning cutter bar suitable for reducing the residual dropped seeds during the breeding harvest in plots. Background Art

[0002] In order to prevent and avoid the occurrence of mixed seeding of different seeds during the harvesting operation of the plot breeding harvester, it is necessary to conduct a comprehensive seed cleaning treatment on the harvesting machinery after each harvesting operation. Among them, the cutter bar of the harvesting machinery is one of the main components where seeds are extremely likely to remain during seed harvesting. Therefore, the cleaning of the cutter bar is extremely important. Currently, the seed cleaning treatment of the cutter bar mainly relies on manual cleaning. Due to the large number of gaps and dead corners between components in the cutter bar structure design, it is easy to leave a large number of seeds that fell on the cutter bar before the threshing operation. This not only makes the cleaning difficult, with low cleaning efficiency, high labor intensity, and high operation cost, but also extremely likely to cause the occurrence of mixed seeding. Summary of the Invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, and in combination with the actual requirements of plot breeding harvesting operations, research and design a cutter bar for reducing the residual dropped seeds during plot breeding harvesting, achieving the purpose of significantly reducing the number of seeds remaining on the cutter bar, reducing the labor intensity of subsequent seed cleaning operations, lowering the cost of seed cleaning operations, and avoiding the occurrence of mixed seeding.

[0004] The purpose of the present invention is achieved as follows: On two relatively arranged side plates, at the rear side of the reciprocating cutter, between the upper part of the arc-shaped bottom plate and the lower part of the spiral auger shaft, a plurality of stalk transporting and vibrating rollers are supported and installed in parallel and rotatably. There is a spacing between adjacent stalk transporting and vibrating rollers. On the outer ends of the same side of the side plates where the plurality of stalk transporting and vibrating rollers are located, driven pulleys are fixedly installed respectively. The driving pulley is fixedly installed on the outer end of the spiral auger shaft. The transmission belt is sleeved and installed on the driving pulley and the plurality of driven pulleys. On the arc-shaped bottom plate, strip-shaped through holes are transversely opened. On the lower side of the arc-shaped bottom plate, at the position below the strip-shaped through holes, a strip-shaped dropped seed recovery box is installed in a mutually communicating and detachable manner. Thus, a cutter bar for reducing the residual dropped seeds during plot breeding harvesting is formed.

[0005] By respectively installing a plurality of stalk transporting and vibrating rollers and a strip-shaped dropped seed recovery box on the upper and lower parts of the arc-shaped bottom plate of the cutter bar assembly, the present invention significantly reduces the residual amount of dropped seeds on the cutter bar assembly and collects them centrally. It has the characteristics of novel, unique, reasonable, and simple structure, reducing the labor intensity of subsequent cutter bar cleaning operations, improving the efficiency and quality of seed cleaning, avoiding the occurrence of mixed seeding, and reducing seed loss, providing technical support for the mechanized harvesting of plot breeding.

[0011] The following is a detailed description of the implementation scheme of the present invention with reference to the accompanying drawings. A combine harvester for plot breeding harvest that reduces the residue of dropped grains includes a combine harvester assembly 1 composed of an arc-shaped bottom plate 8, two relatively arranged side plates 7, a reciprocating cutter 10, a screw auger shaft 2 and a reel 11. On the two relatively arranged side plates 7, at the rear side of the reciprocating cutter 10, between the upper part of the arc-shaped bottom plate 8 and the lower part of the screw auger shaft 2, a plurality of straw transport shaking rollers 9 are supported and installed in parallel and rotatably, with a spacing left between adjacent straw transport shaking rollers 9. Driven pulleys 5 are fixedly installed on the outer ends of the plurality of straw transport shaking rollers 9 on the same side of the side plate 7. A driving pulley 3 is fixedly installed on the outer end of the screw auger shaft 2. A transmission belt 4 is sleeved on the driving pulley 3 and the plurality of driven pulleys 5. A strip-shaped through hole is transversely opened on the arc-shaped bottom plate 8. A strip-shaped dropped grain recovery box 6 is installed in a detachable and communicating manner at the lower side of the arc-shaped bottom plate 8 at the position below the strip-shaped through hole.

[0012] During operation, the screw auger shaft 2 on the combine harvester assembly 1 is driven to rotate by an externally transmitted rotational power. The rotational movement of the screw auger shaft 2 drives a plurality of straw transport shaking rollers 9 to perform rotational movements in the same direction and at the same speed through the driving pulley 3, transmission belt 4 and driven pulleys 5 thereon. The straws cut by the cooperation of the reel 11 and the reciprocating cutter 10 are laid on the straw transport shaking rollers 9 and sent to the screw auger shaft 2, and then sent out of the combine harvester assembly 1. During the transport and shaking process on the straw combine harvester assembly 1, the dropped grains fall from the adjacent gaps of the plurality of straw transport shaking rollers 9 onto the arc-shaped bottom plate 8 and fall into the strip-shaped dropped grain recovery box 6 through the strip-shaped through hole of the arc-shaped bottom plate 8 to complete the collection.

[0013] The combine harvester assembly 1 of this structure achieves the purpose of greatly reducing the amount of dropped grains remaining on the combine harvester, and the technical effect is remarkable.
