Abstract

The utility model discloses a vibrating type inclined sieve plate coal slime screening device. The vibrating type inclined sieve plate coal slime screening device comprises a base, a driving box body, a screening bin body and a grading assembly. The screening bin body reciprocates through a crank connecting rod mechanism, the inner screen drum rotates slowly to switch through hole areas, the surface of the screen drum is dynamically cleaned in cooperation with the cleaning brush bristles, and blocking is reduced. A strip-shaped scraping plate, a sliding rod and an airflow channel are arranged in the auxiliary bin body, so that the cleaning effect is enhanced. According to the device, through ingenious cooperation of a mechanical structure, the cleaning frequency is remarkably reduced while coal slime particles are efficiently screened, operation is simplified, and high practicability and popularization value are achieved.
