When in use, the stone is passed through the feed hopper 2 is poured onto the surface of the No. 1 filter plate 8 in the processing box 1, and then the two hydraulic cylinders 3 are turned on to push the connecting plate 4 to move back and forth. At this time, the two moving plates 5 will move to the center position at the same time, and at the same time drive the two sets of crushing teeth 7 to move. Under the extrusion of the two sets of crushing teeth 7, the stones will be squeezed and crushed. The smaller stones after crushing pass through the No. 1 filter plate 8 and fall downward, and the remaining larger stones continue to be squeezed and crushed. At this time, the No. 1 motor 12 is turned on to drive the No. 1 rotating rod 13 to rotate, and the No. 1 gear 14 will also move accordingly.
