AUTOMATIC CONTROL APPARATUS FOR A GRAIN SEPARATOR ABSTRACT OF THE DISCLOSURE An automatic control apparatus of a grain separator for precisely separating a mixture of soil and grain particles with different specific gravities and shades. The grain separator includes a soil particle discharging opening disposed in the front end region of a separating plate which is inclined and supported at a front elevated position to oscillate back and forth at a larger angle than the tilt angle, and a grain discharging opening disposed in the back end region thereof. The automatic control apparatus is equipped with a light source and a light receiving element in the front end region of said separating plate to detect the intensity of the ray reflected from the mixture of soil and grain particles by means of said light receiving element operating an electromagnet driving means with the signal from the said light receiving element, to allow or block the discharge of particles from the soil particles discharge opening, thus discharging only the soil particles from the discharge opening.
