The second sealing plate 1009 is provided with a corresponding seal at the contact point with the top end of the processing box 10.

[0038] The working principle and use process of this utility model:

[0039] In use:

[0040] The first step: solid medicines are added into the crushing chamber 2, and the first motor 5, the first bevel gear set 4 and the breaker roller 3 cooperate with the crushing chamber 2 to counterattack and crush the solid medicines. The second motor 14 and the second bevel gear set 13 drive the right crushing roller 11 to rotate, and the right crushing roller 11 drives the left crushing roller 11 to rotate through the meshing gear set 12 to crush the crushed medicines again.

[0041] Step 2: The surface of the crushing roller 11 is scraped under the action of the scraper 15 to prevent the medicine from adhering to its surface. The scraper 15 plays a shrinkage buffering effect under the action of the spring 16. After the medicine is crushed, it slides between the static grinding disc 18 and the dynamic grinding disc 19 through the collecting rack 17. Under the action of the third motor 23, the third bevel gear set 22 and the transmission shaft 20 drive the dynamic grinding disc 19 to rotate, further grinding and crushing the medicine. The transmission shaft 20 drives the spiral blade 24 to rotate, which helps the crushed powder fall into the conveying pipe 25 to prevent blockage when falling. The powder falls into the conveying pipe 25 and is transported out by the fourth motor 27 and the auger 26.

[0042] The third step: during the crushing process, under the action of the fan 1010, the medicine powder floating in the air is sucked into the processing box 10 through the dust suction pipe 8 for filtration and treatment. The medicine powder scattered and floating in the crushing chamber 2 is sucked into the dust suction pipe 8 through the opening slot 6. The first filter screen 7 prevents large particles of the crushed solid medicine from entering the opening slot 6. After the crushing is completed, the corresponding valve on the connecting pipe 9 can be closed, and the first sealing plate 1005 is pulled to contact the upper end of the processing box 10 under the action of the electric telescopic rod 1004. The first sealing plate 1005 and the processing box 10 are in contact with each other. Corresponding seals are provided between the contact between the first sealing plate 1005 and the processing box 10, so that the blowing pipe 1006 is lowered into the processing box 10, and the external pipe 1007 is connected to the external blowing equipment. The air is blown to the second filter screen 1001 through the external pipe 1007 and the blowing pipe 1006, so that the filtered medicine powder falls and the permeability of the second filter screen 1001 is maintained. The corresponding valve of the outlet pipe 1011 is opened to collect and process the medicine powder.
