A feeding slot is formed in the top plate of the box, and a feeding pipe is welded and fixed in the feeding slot of the top plate of the box. An installation plate one is welded and fixed to the upper half of the left outer wall of the box, and a crushing motor is fixed to the surface of the installation plate one through bolts.
