Turning plate type screening device

Disclosed is a turning plate type screening device. A screen plate is arranged on a rack of the turning plate type screening device. A vibration motor is arranged on the screen plate. The screen plate is connected with a rotary shaft and is driven by a telescoping cylinder to rotate around the rotary shaft. The rotary shaft is arranged between the vibration motor and the output end of the telescoping cylinder. Compared with the traditional mode that a vibration motor and a telescoping cylinder are located at the same end of a hinged shaft, the turning plate type screening device enables the rotary shaft to be arranged between the vibration motor and the telescoping cylinder, the self-weight of the vibration motor indirectly serves as a counterweight, force at the two ends of the screen plate can be better balanced, impact force generated when the screen plate rotates or returns can be reduced, rotation is more flexible, more power and energy of the motor are saved, and cost is further reduced. Moreover, the v
