[0026] The lifting mechanism 5 in this embodiment includes a lifting plate 501 and a lifting cylinder 504.

[0027] Working principle of the utility model:

[0028] Place the collection bucket 6 in the circular groove 507 on the bearing plate 506. The cylinder 504 acts to push the connecting frame 502 upward, and the lifting plate 501 and the bearing plate 506 also move upward accordingly, thereby driving the collection bucket 6 upward, so that the bucket opening of the collection bucket 6 communicates with the opening of the hammer grinding machine case 401 and the cover plate 416 can cover the bucket opening of the collection bucket 6. Open the hopper cover 302 and pour the raw materials into the feed hopper 301. The raw materials in the feed hopper 301 fall into the conveying pipe 303. The first motor 311 drives the first driven pulley 310 to rotate. Under the driving action of the first transmission belt 312, the first driving pulley 309 is driven to rotate, and the spiral shaft 304 and the spiral blade 305 also rotate accordingly. The spiral blade 305 pushes the raw materials in the conveying pipe 303 to move axially, and the raw materials can be pushed into the discharge pipe 415. The raw materials in the discharge pipe 415 fall into the hammer grinding machine case 401 under the action of their own gravity. The second motor 408 drives the second driving pulley 407 to rotate. Under the driving action of the second transmission belt 406, the second driven pulley 405 is driven to rotate, and the rotating shaft 402 also rotates accordingly. The rotating shaft 402 drives the hammer grinding cylinder 403 to rotate at a high speed, thereby driving the hammer head 404 to rotate at a high speed. The high-speed rotating hammer head 404 impacts, shears and tears the raw materials so that the raw materials are crushed. At the same time, the raw materials rush from the high-speed rotating hammer head 404 to the screen 412 under the action of their own gravity. The particles in the crushed raw materials smaller than the screen hole size of the screen 412 pass through the screen 412 and fall into the collection box 6. The raw materials larger than the screen hole size are retained on the screen 412 and continue to be struck and ground by the hammer head 404 until they are crushed to the required discharge particle size and finally discharged through the screen 412.

[0029] The utility model drives the connecting block 413 to vibrate through the vibration motor 414, and the connecting block 413 drives the screen frame 411 and the screen 412 to vibrate, which can avoid the blockage of the screen holes of the screen 412; the utility model drives the collection bucket 6 to lift and lower through the lifting mechanism 5, and the collection bucket 6 can be lifted to the opening of the hammer grinding machine case 401, and the cover plate 416 can cover the bucket opening of the collection bucket 6, playing a dust-proof role. At the same time, a hopper cover 302 is arranged above the feed hopper 301. When the hammer grinding mechanism works, it can avoid the dust from floating out above the collection bucket 6 and the feed hopper 301, thus effectively avoiding the occurrence of dust flying.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
