Abstract
The utility model discloses a vibrating screen, which comprises a screen box, a vibration exciter, side plates and multi layers of sieve plates. The upper end surface of the screen box is inclined at a certain angle. The side plates are symmetrically arranged left and right. The multi layers of sieve plates are arranged between the two side plates. Each sieve plate is inclined at the same angle with the upper end surface of the screen box respectively. The vibration exciter arranged between the two side plates crosses over the two side plates and is driven to run by a motor. Both the two side plates and the multi layers of sieve plates are arranged in the screen box. The motor is fixed onto the screen box. A plurality of spring damping units are arranged between the two side plates and the screen box. According to the technical scheme of the vibrating screen in the utility model, the screening operation is realized by means of the multi layers of sieve plates. Since the multi layers of sieve plates are inclined at a certain angle, the screening effect is better. Meanwhile, the vibration performed by the vibration exciter is stable.
