High polymer material crushing device

The utility model discloses a high polymer material smashing device which comprises a smashing box, a smashing device is arranged in the smashing box, discharging ports are formed in the two sides and the bottom of the smashing box, screening sleeves are arranged on the two sides of the smashing box, and screening plates are fixedly connected into the screening sleeves. The two sides of the crushing box are fixedly connected with motors, and the output ends of the motors are fixedly connected with worms. Materials are screened by the V-shaped screening plate through the screening sleeve, so that smaller materials fall down through the screening sleeve and the screening plate, and then the motor drives the screening sleeve through the worm gear and the worm to pour larger materials into the circulating opening and the interior of the crushing box for secondary crushing, so that the crushing and screening device has the advantage of being convenient to crush and screen; the problems that when an existing high p
