DISTRIBUTING VALVE FOR CONCRETE PUMP, CONCRETE PUMP AND CONTROL METHOD THEREOF AND CONCRETE PUMP VEHICLE

摘要

A distributing valve for concrete pump, a concrete pump and a control method thereof and a concrete pump vehicle are disclosed. The distributing valve includes a valve body (200) and a wear resistant plate (300), the valve body (200) has a first material suction pipe (210) and a first material pumping pipe (220), and the wear resistant plate (300) has a material transporting opening. The front ends of the first material suction pipe (210) and the first material pumping pipe (220) respectively have cutting rings for matching with the wear resistant plate (300), the back end of the first material suction pipe (210) is communicated with an outlet (401) of a hopper (400), and the back end of the first material pumping pipe (220) is rotatablely communicated with a transporting pipe of the concrete pump. The valve body (200) is driven by a driving mechanism (500) to switch between a first state and a second state, in the first state, the opening of the cutting ring of the first material suction pipe (210) is communicated with the material transporting opening, and in the second state, the opening of the cutting ring of the first material pumping pipe (220) is communicated with the material transporting opening. The distributing valve has high pressure withstanding capacity and can improve the material sucking performance of the concrete pump.
