2. A kind of screening and impurity removal equipment for processing traditional Chinese medicine pieces according to the present invention, by placing the collection box at the upper end of the bottom plate, then placing the Chinese medicine pieces to be screened inside the screening box, and then starting the fourth motor and the third Five motors, the fourth motor drives the eccentric block to rotate, so that the eccentric block continuously squeezes the screening box, causing the screening box to move up and down, and recovers under the action of the spring damper, which can cause the screening box to vibrate, which can affect the traditional Chinese medicine pieces. Screening is carried out so that the granular impurities in the traditional Chinese medicine pieces are removed through the sieve holes. At the same time, the second threaded rod is rotated under the action of the fifth motor, so that the traverse rod slides left and right. When the transverse rod slides left and right When the rack and the second gear cooperate, the turntable is rotated, and the turntable uses the pin to drive the swing rod to rise and fall, and the swing rod swings under the limit of the sliding sleeve, which can cause the flipping plate to swing back and forth, causing the flipping plate to swing back and forth.
