[0030] The working process of this utility model is as follows: When using this pharmaceutical pulverizing device, the pharmaceutical is first fed into the pretreatment box 101. The blades of the cutting component 301 rotate under the drive of a motor, cutting large pieces of pharmaceutical into smaller pieces. The pulverized pharmaceutical is then orderly conveyed to the guide tube 103 via the spiral conveyor of the conveying component 302, entering the pulverizing box 102. Inside the pulverizing box 102, the pharmaceutical is further pulverized and cut by the cutting component 301. The pulverized pharmaceutical powder passes through the filter screen 201. Qualified powder falls into the collection box 210, while unqualified powder rolls down the filter frame 2 and the filter screen 201 to the inlet of the powder-specific conveying pump 4. The filter screen 201 is then returned to the crushing chamber 102 for further crushing to prevent clogging. The displacement component 205 can be activated, which drives the lead screw nut and its connected connecting rod 204 to move up and down. The ball hammer 203 strikes the filter frame 2 to prevent clogging. At the same time, after the ball hammer 203 is moved to the highest point, the electric push rod 206 and the electric telescopic rod 208 work together to drive the brush plate 209 to clean the surface of the filter screen 201 and prevent clogging. The filter screen 201 is fixed to the filter frame 2 with bolts, and different diameter filter screens 201 can be replaced.
