[0033] Working principle: When in use, the Chinese medicine pills to be screened are put into the drum 501 from the feed pipe 505. Since the drum 501 is set in a frustum-shaped cylinder, the inner wall of the drum 501 is inclined. Then, under the action of the gravity of the Chinese medicine pills themselves, the Chinese medicine pills move along the inner wall of the drum 501 from the end with a smaller diameter of the drum 501 to the end with a larger diameter of the drum 501, so that the Chinese medicine pills pass through the first sieve hole 502, the second sieve hole 503 and the third sieve hole 504 in sequence, thereby facilitating the screening of the Chinese medicine pills. Screening is performed. When the diameter of the Chinese medicine pills corresponds to the aperture of the first sieve hole 502, the second sieve hole 503, or the third sieve hole 504, the Chinese medicine pills fall from the corresponding sieve hole into the corresponding collecting tank. During the movement of the Chinese medicine pills, the first motor 509 is turned on to rotate the first driving gear 510. Since the first driving gear 510 is engaged with the teeth 508 on the feeding pipe 505, the roller 501 is driven to rotate, thereby increasing the probability of the Chinese medicine pills contacting the sieve holes, thereby improving the screening effect.

[0034] The second motor 609 is turned on to rotate the second driving gear 610, which is engaged with the driven gear 608 on the rotating rod 605, thereby driving the rotating rod 605 to rotate. The rotating rod 605 is provided with a brush plate 606. During the movement of the Chinese medicine pills, the brush plate 606 continuously moves the Chinese medicine pills in the drum 501 along the circumferential direction of the inner wall of the drum 501, thereby further increasing the probability of the Chinese medicine pills contacting the sieve holes, thereby improving the screening effect.

[0035] At the same time, the air pump is turned on to drive the outside air from the connecting pipe 706 through the inner groove 701 to be sprayed from the first nozzle 702, the second nozzle 703, and the third nozzle 704. The first nozzle 702, the second nozzle 703, and the third nozzle 704 are inclined toward the smaller end between the roller 501, that is, they are sprayed in the opposite direction of the movement of the Chinese medicine pills, thereby playing a buffering role on the Chinese medicine pills, thereby prolonging the movement time of the Chinese medicine pills in the roller 501, thereby increasing the probability of the Chinese medicine pills contacting the sieve holes, and thus improving the screening effect. The diameters of the first nozzle 702, the second nozzle 703, and the third nozzle 704 are increased in sequence, thereby forming a screening effect for Chinese medicine pills of different sizes. Different sizes of buffering forces, due to the different masses of Chinese medicine pills of different sizes, facilitate Chinese medicine pills of different sizes to stay in the corresponding sieve hole pipes. For example, the diameter of the first nozzle 702 is the smallest, so that the buffering force of the airflow ejected by the first nozzle 702 on the Chinese medicine pills is smaller. At this time, under the action of the airflow ejected by the first nozzle 702, the speed of the Chinese medicine pills of corresponding sizes at one end inside this section of the sieve hole pipe is very slow until the Chinese medicine pills fall into the first collecting tank 2. The buffering force on the larger Chinese medicine pills cannot form a large hysteresis effect on the Chinese medicine pills, so the larger Chinese medicine pills still roll down, thereby facilitating the screening of Chinese medicine pills of different sizes.
