Abstract
The utility model discloses a novel banana vibrating screen. A transmission device comprises gear vibration exciters, a motor, a bearing seat, an end universal coupling and a middle universal coupling. An input belt pulley of an input shaft head of the bearing seat is connected with an output belt pulley of an output shaft head of a motor through a triangular belt. The input shaft head of the bearing seat is connected with an adjacent gear vibration exciter through the end universal coupling, and the two gear vibration exciters are connected through the middle universal coupling. A screen box comprises sieve plates, side plates and a supporting beam. Fixing sieve plate railway seats are arranged between two adjacent sieve plates, each joint portion of two sides of each sieve plate and each fixing sieve plate railway seat is provided with a dovetail clamping groove, and composite damping springs are installed between the screen box and a screen box supporting seat. According to the novel banana vibrating screen, a sieve plate installing manner is replaced by a clamping structure of a rail seat and the dovetail clamping groove, and therefore interchange of the sieve plates can be achieved on any banana vibrating screen. Due to the addition of transmission of the triangular belt and the bearing seat on the transmission device, the phenomenon that burn-out of the motor and belt dropping of the triangular belt caused by locking of a bearing can be avoided. Due to the usage of the composite damping springs, working noise is reduced, and the phenomenon of spring breakage is avoided.
