If excessive friction or impact is applied during the separation process of soybean and bean pods, the soybean is split into two pieces and damaged lips are formed. The soybean stem and bean pods are excessively crushed, As a result, selective screening is not performed due to selection load, thereby providing a cause of increasing the amount of foreign matter contained in the final harvest.

Therefore, we are now working on soybean harvesting using a soybean thresher with a tractor attached to it, or a soy thresher equipped with an electric motor.

Such soybean harvesting work is a high-frequency operation, and the development of a device capable of carrying out a series of harvesting operations for cutting, conveying, threshing, sorting-sorting and collecting and discharging soybeans is required mainly for soybean cultivation farmers of a large area.

Some farmers use conventional combine harvesters, which are conventionally used for harvesting barley, to harvest soybeans.

However, when soybeans are harvested using conventional conventional combines, the soybean crops laid horizontally after the cutting operation are transferred into the thresher, but in this case, the soybean crops cut off by external vibration or impact fall to the bottom There is a possibility of loss.

In addition, since the cropping process of the conventional crop is mostly performed after the cutting operation to cut the lower end of the crop is performed, the angle of the feeding means is fixed in the course of the feeding operation in the form of collecting the crops on the bottom, If the height is not constant, there is a problem that the cropped crop can not be collected.
