[0027] In a preferred embodiment, the crushing assembly 2 includes a motor 201, the power output shaft of the motor 201 is fixedly equipped with a rotating wheel 202, the outer wall of the rotating wheel 202 is rotatably sleeved with one end of a belt 1 203, the other end of the belt 1 203 is rotatably sleeved with a driving wheel 204, the outer wall of the driving wheel 204 is fixedly mounted with a driven wheel 205, the outer wall of the driven wheel 205 is sleeved with one end of a belt 206, the other end of the belt 206 is sleeved with a pulley 1 207, the outer wall of the pulley 1 207 is fixedly equipped with a pulley 208, the outer wall of the pulley 208 is sleeved with one end of a belt 3 209, the other end of the belt 3 209 is sleeved with a pulley 3 210, and the outer walls of the pulley 2 208 and the pulley 3 210 are both fixedly equipped with cutting blades 211;

[0028] In a preferred embodiment, there are two groups of crushing assemblies 2, and the two groups of crushing assemblies 2 are symmetrically distributed on the outer wall of the support frame 1. The motor 201 is electrically connected to the controller 10. The end of the driving wheel 204 away from the driven wheel 205 is fixedly mounted on the outer wall of the diverter 13. The pulley 208 and the pulley 3 210 are mounted on the outer walls of both sides of the feed hopper 9. The cutting blades 211 are alternately located on the inner wall of the feed hopper 9.

[0029] By utilizing the above structure, the controller 10 transmits a signal, so that the motor 201 can start working, thereby rotating the rotating wheel 202, and driving the driving wheel 204 to rotate synchronously through the belt 1 203, so that the diverter 13 and the pulley 2 208 can rotate.
