[0047] The support assembly 200 further includes a side plate 202. A side plate 202 is respectively disposed on both sides of the top of the support frame 201. A limiting column 203 is respectively disposed on both sides of the bottom of the grinding seat 409. The limiting column 203 is movably plugged with the side plate 202. The limiting column 203 is distributed on both sides of the grinding seat 409.

[0048] The side plate 202 cooperates with the limiting column 203 so that the grinding seat 409 can only move up and down.

[0049] The discharging assembly 300 includes a discharging barrel, a limiting sleeve 304 and a discharging pipe 305. The edge of the top of the discharging barrel is fixedly connected to the inner wall of the grinding groove 106, and the inner ring of the top of the discharging barrel is fixedly connected to the bottom end of the lower grinding plate 412.

The discharging pipes 305 are connected to the inner cavity of the discharging barrel, and the top of the discharging barrel is connected to the grinding groove 106.

[0050] After the block raw material is ground, it becomes raw material powder and arrives in the grinding tank 106 . The raw material powder falls into the discharge cylinder, and then passes through the discharge cylinder to the discharge pipe 305 and is discharged from the discharge pipe 305 .

[0051] The discharge cylinder is composed of an inner cylinder 301 and an outer cylinder 302 , and the bottoms of the inner cylinder 301 and the outer cylinder 302 are connected.

[0053] The specific implementation method is as follows: block raw materials are put into the feeding trough 102, the block raw materials are located on the top of the gathering disk 401, the motor 405 controls the rotation of the pulley 2 406, the pulley 2 406 rotates with the pulley 1 404 through the transmission belt 407, the pulley 1 404 rotates with the grinding mechanism 400, the rotating gathering disk 401 and the arc plate 402 make the block raw materials be gathered to the middle of the gathering disk 401, so that the block raw materials put into the feeding trough 102 enter the channel of the feeding barrel 403, and the block raw materials pass through the internal channel of the feeding barrel 403 to reach between the upper grinding plate 411 and the lower grinding plate 412;

[0054] The driving motor 414 controls the mounting seat 410 to rotate, so that the grinding seat 409 vibrates up and down, so that the gap between the upper grinding plate 411 and the lower grinding plate 412 is continuously expanded and reduced. The mounting seat 410 prevents the grinding seat 409 from rotating, so that the grinding seat 409 and the lower shell 103 rotate relative to the upper grinding plate 411;

[0055] The block raw material is ground by the upper grinding plate 411 and the lower grinding plate 412 which rotate relatively. In the process that the gap between the upper grinding plate 411 and the lower grinding plate 412 is continuously expanded and reduced, the block raw material is squeezed and crushed by the upper grinding plate 411 and the lower grinding plate 412, and then continues to participate in grinding;

[0056] The block raw material is ground into raw material powder and arrives in the grinding tank 106. The raw material powder falls into the discharge cylinder, and then passes through the discharge cylinder to the discharge pipe 305 and is discharged from the discharge pipe 305.

[0057] When cleaning is required, since the feed trough 102, the grinding mechanism 400 and the discharge assembly 300 are connected from top to bottom, the cleaning liquid or the cleaning airflow passes through the feed trough 102, the grinding mechanism 400 and the discharge assembly 300 in sequence from top to bottom. During the process, the cleaning liquid or the cleaning airflow rubs the inner side of the feed trough 102, the grinding mechanism 400 and the discharge assembly 300. During this period, the mounting seat 410 vibrates the discharge assembly 300 and the lower grinding plate 412 to cause the attached particles to fall off, and the gathering plate 401, the curved plate 402 and the feed barrel 403 rotate, causing the gathering plate 401, the curved plate 402 and the feed barrel 403 to rub against the cleaning liquid or the cleaning airflow, making cleaning very convenient and allowing the grinder to be cleaned quickly and effectively.

[0058] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
