In this embodiment, the elastic member is configured as a spring 301, and the number of springs 301 is multiple, and the multiple springs 301 are fixedly connected to the outer circumferential wall surface of the crushing drum 300 at one end, and the other end is fixedly connected to the inner wall surface of the crushing box 100. Initially, under the joint action of the multiple springs 301, the crushing drum 300 is in a stationary state; a spring 301 is provided on the top circumferential wall surface of the crushing drum 300. A feeding port is connected with the top opening of the crushing box 100, and the feeding port is used to receive materials. A sieve hole 302 is arranged on the bottom circumferential wall surface of the crushing box 100, and the sieve hole 302 is connected with the bottom opening of the crushing box 100, and the sieve hole 302 is used to discharge the crushed materials. A central shaft 200 is arranged in the crushing barrel 300, and the central shaft 200 and the crushing barrel 300 are coaxially arranged and can rotate relatively. The central shaft 200 can be rotatably penetrated on the mounting hole 102, and the diameter of the central shaft 200 is smaller than the aperture of the mounting hole 102. A crushing shaft 201 is sleeved on the central shaft 200, and a connecting shaft 202 parallel to the axis of the crushing shaft 201 is arranged on the crushing shaft 201 along the radial direction of the crushing shaft 201, and a breaking hammer 203 is sleeved on the connecting shaft 202, and the breaking hammer 203 extends along the radial direction of the crushing shaft 201, and the breaking hammer 203 is used to crush materials.

It is understandable that the breaker hammer 203 can be configured to be rotatably sleeved on the connecting shaft 202, or can be configured to be fixedly sleeved on the connecting shaft 202.

When in use, the material enters the crushing drum 300 from the top opening of the crushing box 100 through the feed port, and the central shaft 200 drives the crushing hammer 203 to crush the material through the crushing shaft 201.
