The adjusting screws 6 are set to drive the butt plate 8 to move up and down when rotating, so that the butt plate 8 can limit the rotation of the roller 4 when it moves downward to contact the ground. The top of the crushing box 1 is fixedly connected with a connected drop hopper 2, and the drop hopper 2 is set to guide the waste to be crushed and recycled into the inside of the crushing box 1. The inside of the crushing box 1 is symmetrically rotatably connected with cutting rollers 10, and the outer walls of the two groups of cutting rollers 10 are evenly fixedly connected with a plurality of cutting knives 11. The cutting rollers 10 are set to drive each group of cutting knives 11 to rotate when rotating, so that each group of cutting knives 11 can crush the waste falling between the two groups of cutting rollers 10.

[0032] Please refer to Figure 1-3 A motor 19 is symmetrically fixedly connected to one side wall of the crushing box 1.
