Detailed Description of the Invention The present invention relates to an automatic control device for the inclination angle, particularly in the lateral direction, of the sorting plate of a swing sorting device. Sorting in a swinging sorting device in which a detection sensor is installed at the boundary with mixed rice or between mixed rice and brown rice to automatically control the horizontal inclination angle of the sorting plate. This invention relates to an automatic control device for plates.

Conventionally, in order to detect the distribution state of grains on the sorting plate of a shaking sorter, a detection sensor is provided at the boundary between brown rice and mixed rice, for example, and the sensor detects the state of the boundary between brown rice and mixed rice. Detects and transmits a signal to a motor that can rotate forward and backward,
It is known that the partition plate at the outlet is moved laterally by reverse rotation of the motor, but in this known example, the partition plate simply moves, and the grains on the sorting plate are moved. Since the method does not correct the particle distribution state to the best condition, the sorting performance was not sufficient.

Therefore, in the present invention, the sorting work is always performed in an optimal distribution state, and the supply side is higher than the opposite outlet side and inclined vertically, and the launch side is higher than the swinging side and is also inclined laterally. When a desired boundary line is drawn on the oscillating sorting plate that is used for distribution, a boundary detection sensor is installed on the boundary line or on both sides of the boundary line (-J). A wind selection room is provided at the lower part of the automatic sorting plate angle control device of the swinging sorting device connected to drive the inclination angle adjustment device in the lateral force direction and the hulling room, and an elevator is attached to the side of the wind selection room.
