[0038] In the above scheme, if Figure 3 As shown, the No. 1 grinding tooth 7 and the No. 2 grinding tooth 8 are clearance-matched, and the clearance between the No. 1 grinding tooth 7 and the No. 2 grinding tooth 8 gradually decreases from top to bottom.

[0039] During use, the medicinal materials to be crushed are put into the crushing box 3 through the opening thereof and are preliminarily crushed by the crushing mechanism 14. In the process of the preliminarily crushed medicinal materials entering the screening cylinder 4, the large particles of medicinal materials are screened on the filter screen through the filter screen, and the medicinal materials with qualified particles are discharged from the bottom of the screening cylinder 4 through the filter. At intervals, the screening cylinder 4 is rotated to generate centrifugal force during its rotation, and the large particles of medicinal materials remaining on the filter screen are moved toward the inner wall of the screening cylinder 4 under the action of centrifugal force and enter the grinding box 2 through the screening holes 5 on the screening cylinder 4.

The qualified medicinal materials enter the screening drum 4, pass through the filter screen and enter the No. 1 material receiving chamber in the material receiving box 1 through the No. 1 drop-out end 11 from the bottom end of the screening drum 4. The screening drum 4 is rotated to allow the medicinal materials with larger particles filtered on the filter screen to enter the grinding box 2 through the screening holes 5 on the screening drum 4 under the action of centrifugal force. The large-particle medicinal materials entering the grinding box 2 are further ground by the rotating grinding 6 and the No. 2 grinding teeth 8 on the inner wall of the grinding box 2 to obtain medicinal materials with qualified particles.

A driving motor for driving any one of the crushing shafts to rotate is horizontally fixed on the side wall of the crushing box 3, and the output shaft of the driving motor is coaxially connected to any one of the crushing shafts passing through the crushing box 3 through a coupling.

[0053] In the above scheme, by starting the driving motor to drive the driving gear on its output shaft and the crushing shaft coaxially connected thereto to rotate, under the meshing relationship between the two driving gears, the other crushing shaft can be driven to rotate synchronously in the opposite direction, thereby enabling the two crushing shafts to rotate in opposite directions, thereby driving the multiple crushing blades on their respective shafts to rotate in coordination, so as to crush the medicinal materials.
