A support plate is fixedly installed at the bottom of the inner wall of the feed hopper. A long plate is placed on the support plate. Two rows of diversion cylinders are uniformly and fixedly installed on the long plate, and each row of diversion cylinders is provided with a plurality of them. A cross plate is fixedly installed together on the inner walls of two sides of the sieve box. Side openings are opened on the adjacent two sides of the sieve box. Two bottom plates are symmetrically and fixedly installed on the inner walls of the adjacent two sides of the sieve box. A sieve frame is fixedly installed at the top of the bottom plate and the bottom of the cross plate. A sieve mesh is fixedly installed in the sieve frame.
