Beschreibung
Zusammenfassung:	The invention discloses a solid screening device for a feed processing mechanism. The solid screening device comprises a device body, wherein a cavity is arranged in the device body; a tertiary screening mechanism is arranged in the cavity; the tertiary screening mechanism moves up and down in the cavity through a transmission mechanism; the tertiary screening mechanism is matched with the transmission mechanism for use; the transmission mechanism can drive the tertiary screening mechanism to move up and down, so that manual shaking action of a professional pharmacist is imitated by up-down movement, and therefore, unloading quality of the tertiary screening mechanism is high; the two sides of an enclosing frame plate are equipped with first openings in a penetrating mode; the left and right ends of a first screen net are separately inserted into the two first openings; a second screen net is arranged below the first screen net; after being screened, relatively thick materials are positioned on the first scre
