Turning plate mechanism for garbage classification

The invention discloses a turning plate mechanism for garbage classification. The turning plate mechanism comprises a bearing base, a turning plate shaft, a motor, a turning plate and sensors, wherein one end of the turning plate shaft is fixed to the bearing base, the other end of the turning plate shaft is connected to the motor, the turning plate shaft is provided with the turning plate, the turning plate is driven by the motor so as to turn within a certain angle range in a reciprocating mode, and the sensors are arranged at the two turning limit positions of the turning plate. According to the turning plate mechanism, when injection syringes are shorn and syringe needles need to be collected, the motor drives the turning plate to turn to the sensor on one side, the syringe needles are held, and syringe cylinders fall into a garbage bag; when the syringe cylinders need to be collected, the motor rotates reversely to drive the turning plate to turn to the sensor on the other side, then the syringe cylinders are held, and the syringe needles fall into the garbage bag. Thus, the syringe cylinders and the syringe needles can be collected in a classified mode conveniently and quickly.
