[0063] Specifically, during the rotation of the support housing 6, the rotation of the support housing 6 can drive the third bevel gear 20 to move around the fourth bevel gear 21. At the same time, through the meshing of the third bevel gear 20 and the fourth bevel gear 21, it drives the stirring rod 7 to rotate, so that the stirring rod rotates around the stirring rod 7, thereby further improving the stirring efficiency and at the same time further improving the screening efficiency.

[0064] In this embodiment, during use, after the operator adds traditional Chinese medicine pieces into the screening barrel 5 through the feeding bin 2, the operator controls the first motor 13 to work. The operation of the first motor 13 can control the driving rod and the second bevel gear 11 to rotate. At the same time, the rotation of the second bevel gear 11 drives the first gear 9 to rotate through the engagement with the first bevel gear 10. Then, the rotation of the first gear 9 drives the support housing 6 to rotate through the engagement with the first annular rack 8. As a result, the stirring rod 7 and the stirring bar can move around the support housing 6. At the same time, the rotation of the support housing 6 can drive the third bevel gear 20 to move around the fourth bevel gear 21. At the same time, the rotation of the third bevel gear 20 drives the stirring rod 7 to rotate through the engagement with the fourth bevel gear 21, so that the stirring bar moves around the stirring rod 7, thereby realizing the stirring of the traditional Chinese medicine pieces. During the stirring process, when the driving rod rotates, it can drive the second pulley 19 to rotate. At the same time, the rotation of the first pulley 18 is driven through the conduction of the belt. The rotation of the first pulley 18 drives the driving column 17 and the third gear 16 to rotate. At the same time, the rotation of the third gear 16 drives the two second gears 14 to rotate synchronously through the engagement with the second gear 14, and further enables the positioning column to move around the second gear 14. During the movement of the positioning column, the cooperation between the positioning column and the side wall of the positioning groove 15 can drive the support plate 4 and the screening barrel 5 to shake in the height direction, so that the smaller traditional Chinese medicine pieces can be discharged from the screening holes of the screening barrel 5 and collected through the discharge port 3. After the smaller traditional Chinese medicine pieces are screened, the operator opens the discharge control valve, and the larger traditional Chinese medicine pieces can be discharged from the screening box 1 through the discharge pipe 23 and the discharge port 3 and collected.
