When passing through the roller at the end of the belt conveyor 1, due to the inertia of the belt conveyor 1, if the material contains foreign matter, when the foreign matter passes through the rejection air bag 5, the solenoid valve of the rejection air bag 5 in the area is opened to blow air, and the debris in the material is blown down. The material after one rejection moves forward under the action of inertia and enters the first material inspection outlet 10, and is drawn back to the feed end of the belt conveyor 1 through the return pipe 21.
