PUMPING MECHANISM

摘要

A pumping mechanism comprises a pumping system (200) and an underframe (100). The pumping system (200) includes a pumping power device, a hopper (240), an elastic buffering mechanism (300) and a connecting rod (400). The elastic buffering mechanism (300) is fixedly connected with one of the pumping power device and the underframe (100) to form a fixed connection point, and is pivotally connected with the other of the same to form a hinge point. The fixed connection point and the hinge point are arranged at a predetermined distance. Both ends of the connecting rod (400) are hinged to the hopper (240) and the underframe (100), respectively. The connections between the pumping system (200) and the underframe (100) of the pumping mechanism form a three-hinged structure, which ensures stability between the pumping system (200) and the underframe (100) during operation of the pumping mechanism, and reduces the vibration transmitted from the connecting rod to the underframe (100). The elastic buffering mechanism can buffer the vibration and impact of the pumping power device to the underframe (100). The pumping mechanism allows the three-hinged structure to automatically adapt the position relationship between the pumping system and the underframe (100) when the pumping system has a processing error, so that the pumping system and the underframe (100) can be conveniently assembled.
