[0024] The utility model is further described below in conjunction with the accompanying drawings:

The guide plate 6 is inclined and has a plurality of discharge holes. The guide plate 6 is located below the feed funnel 201. The guide plate 6 is used to disperse the materials to prevent all the raw materials from piling up below the feed funnel 201.
[0026] A crushing mechanism is arranged in the crushing barrel 2, and the crushing mechanism also includes a filter plate 301 bolted between the inner walls of the crushing barrel 2, a rotating motor 302 is bolted to the top of the crushing barrel 2, and the output end of the rotating motor 302 is connected to a rotating shaft 303 through a coupling, and the rotating shaft 303 extends into the crushing barrel 2, and a mounting block 304 is fixedly connected to the rotating shaft 303, and a U-shaped mounting frame 305 is bolted to the outer wall of the mounting block 304, and a rolling roller 306 located above the filter plate 301 is rotatably connected between the mounting frames 305, and the raw materials are crushed and crushed by the rolling roller 306.
[0027] An auxiliary mechanism is provided on the mounting block 304, which includes a transverse plate 401 bolted to the mounting block 304, a connecting frame 408 connected between the mounting frame 305 and the transverse plate 401, and the stability of the transverse plate 401 is improved by the connecting frame 408, a plurality of fixed teeth 402 are welded to the bottom of the transverse plate 401, a movable plate 403 is slidably connected to the top of the transverse plate 401, a spring 404 is connected between the movable plate 403 and the mounting block 304, and a movable tooth 405 is welded to the bottom of the movable plate 403, the fixed teeth 402 and the movable teeth 405 abut against the filter plate 301, a through hole is provided on the transverse plate 401, and the movable teeth 405 move in the through hole, a knocking rod 406 is fixedly connected to the end of the movable plate 403, and a plurality of protrusions 407 are fixedly connected to the inner wall of the crushing cylinder 2, and the fixed teeth 402 and the movable teeth 405 are conical with the tips facing the rolling roller 306, so as to facilitate the dispersion of the compacted raw materials.
[0028] A knocking mechanism is arranged below the crushing mechanism, and the knocking mechanism includes a plurality of levers 501 welded on the rotating shaft 303. A plurality of elastic columns 502 are fixedly connected to the bottom of the filter plate 301. The levers 501 and the elastic columns 502 are arranged alternately. When the rotating shaft 303 rotates, the levers 501 are also driven to rotate. When the levers 501 contact the elastic columns 502, the elastic columns 502 are deformed. When the levers 501 separate from the elastic columns 502, the elastic columns 502 are reset under the action of elastic force, thereby vibrating the filter plate 301 to facilitate material unloading.
[0029] Working principle: When in use, the raw materials that have been preliminarily crushed are added into the crushing cylinder 2 through the feeding funnel 201, and the raw materials fall evenly onto the filter plate 301 under the guidance of the guide plate 6, and the rotating motor 302 is started, and the rotating motor 302 drives the rotating shaft 303 to rotate, and the rotating shaft 303 drives the mounting block 304 to rotate, and the mounting block 304 drives the rolling roller 306 to rotate counterclockwise on the filter plate 301 to further crush the raw materials.

When the knocking rod 406 contacts the protrusion 407, the knocking rod 406 drives the movable plate 403 and the movable tooth 405 to move, and the spring 404 is compressed. When the knocking rod 406 separates from the protrusion 407, the movable plate 403 is moved under the action of the elastic force of the spring 404 By resetting the movable teeth 405 and the fixed teeth 402, the spacing between the movable teeth 405 and the fixed teeth 402 is constantly changed, which is convenient for squeezing and crushing the particles stuck between the fixed teeth 402 and the movable teeth 405 to avoid affecting the flipping effect. When the movable plate 403 is reset, a certain vibration will be generated, which is convenient for shaking off the particles stuck between the fixed teeth 402 and the movable teeth 405. When the fixed teeth 402 and the movable teeth 405 flip the crushed raw materials, it is also helpful to make the raw materials that meet the requirements fall from the filter plate 301. When the rotating shaft 303 rotates, it also drives the lever 501 to rotate. When the lever 501 contacts the elastic column 502, the elastic column 502 will be deformed. When the lever 501 is separated from the elastic column 502, the elastic column 502 is reset under the action of elastic force, thereby causing the filter plate 301 to vibrate, which is convenient for unloading.
