Description

DETAILED DESCRIPTION OF THE INVENTION The present invention, for example, separates grains into brown rice, paddy, and mixed rice by shaking a sorting plate tilted back and forth and from side to side while the grains flow down on the sorting plate. Let's do it! This relates to an automatic control device for a separate gIJII machine.

According to the present invention, the position control mechanism 11r of the sorting partition plate that separates the grains sorted 11 by the oscillating sorting plate into brown rice or paddy: 1 is connected to the tilt angle control mechanism of the sorting plate. As a result, the grain condition on the sorting board changes depending on the moisture content of the grain, the deweighing rate, or the supplied wax. Even if the boundary position moves and displaces, it is possible to quickly and appropriately respond to t'L by controlling the position of the front P partition plate and the inclination angle of the sorting plate, and it is always kept constant regardless of the grain size.
