Since the inside of the feeding shell is connected to a conveyor belt through a conveyor roller, it can be used to convey steel ball parts. Grooves are opened at equal intervals on the upper surface of the conveyor belt, and the grooves are set as semicircular grooves, which are convenient for clamping the steel ball parts in the grooves to prevent collision between two adjacent steel ball parts during transportation, and prevent the steel ball parts from sliding during transportation;
