[0033] Open the cover plate 5, put the Chinese medicinal materials into the inner screening frame 14, and close the cover plate 5. At this time, start the drive motor 3 to drive the rotating shaft 8 to rotate. As the rotating shaft 8 rotates, the lower rotating gear 7 is driven to rotate. Through the meshing connection between the lower rotating gear 7 and the gear ring 10, the gear ring 10 rotates. As the gear ring 10 drives the outer screening frame 6 to rotate, the outer screening frame 6 drives the fixed ring 18 to rotate. The fixed ring 18 rotates inside the fixed round seat 9.

Through the meshing connection between the lower rotating gear 7 and the gear ring 10, the gear ring 10 rotates. As the gear ring 10 drives the outer screening frame 6 to rotate, as the outer screening frame 6 drives multiple support plates 13 to rotate, as the support plate 13 drives the middle screening frame 12 and the inner screening frame 14 to rotate, and the circular surface 15 is moved to contact the medicinal materials, the medicinal materials are moved. At this time, the screening frequency conversion fan 4 is started to draw the external air inward. , so that the medicinal materials are screened, smaller medicinal materials will flow outward through the inner screening holes 17, and the medicinal materials that fall into the middle screening frame 12, and the holes smaller than the middle screening holes 16 will flow to the inside of the outer screening frame 6, thereby screening the device. After the screening is completed, the screening frequency conversion fan 4 in the low-frequency state blows the smallest-sized medicinal materials inside the outer screening frame 6 to the outside, and the medicinal materials will fall into the collecting circular groove 11.
