Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to a combine harvesting and conveying device using soybean as a harvest grain.

“Conventional technology” In soybean harvesting work, the cutting height is originally low, and when the vehicle is tilted by riding a running wheel or crawler on the left and right sides on the ridge surface and tilting the machine, field soil and ridges will grow along with the grain. Even the cutting soil of the above is scraped into the cutting section at the same time, and there is a drawback that a large amount of so-called slag particles are generated which causes the surface of the soybeans to be rubbed and soiled by the mixing and stirring action with the mixed soil during the transportation. It was As one of the countermeasures against this grain, a punched iron plate is used for the bottom plate of the feeder house, for example
There is a means to remove foreign matter by opening a through hole for dropping foreign matter in the bottom plate described in Japanese Patent No. 37.

"Problems to be solved by the device" However, in the conventional means as described above, the leakage area is so small that foreign matter such as soil is not sufficiently leaked, or the grain is moving on the bottom plate. In that case, not only is there inconvenience that the smooth movement of the grain is hindered by the continuous unevenness of the flat surface of the bottom plate and the hole, but a lot of damaged grains are generated due to the grain contacting the hole edge during the movement. There were some drawbacks such as making it happen.

Therefore, according to the present invention, the cutting grain culm of the cutting unit is sent to the threshing unit via the bottom plate of the supply chamber and the internal conveyor, and is parallel and orthogonal to the conveyor direction. In a combine harvesting and conveying device that forms a plurality of slits at substantially equal intervals in a direction, a plurality of round rods having circular end faces are provided in parallel with the convey direction of the conveyor, and substantially in a direction orthogonal to the convey direction of the conveyor. The bottom plate of the supply chamber is formed by providing the plurality of round bars at equal intervals.

[Operation] Therefore, since the slit is formed by a plurality of round bars provided in parallel, the width of the upper surface of the slit is formed by a size obtained by adding the minimum width of the slit and the diameter of the round bar, and the contaminants conveyed by the conveyor are formed. The removal efficiency can be improved more easily than before, and spherical grains such as soybeans can be in line or point contact with the round bar to reduce the generation of dirt particles more easily than the conventional flat bottom plate. Furthermore, the bottom plate formed by the round bar can easily expand the falling area without lowering the strength, and it can be easily applied to various grains by changing the diameter of the round bar and the installation interval according to the type of grain. Can be applied to.
