Abstract

The invention discloses a control method of a pumping mechanical system, which comprises following steps: (1) detecting material level information in a hopper of a pump truck to generate a material level signal; (2) performing CAN communication between a pump truck controller and a mixer truck controller, so that the pump truck controller can send the material level signal and an acquired pumping speed signal of the pump truck to the mixer truck controller; and (3) according to the material level signal and the pumping speed signal, controlling the displacement of an oil pump and the rotate speed of an engine of the mixer truck by the mixer truck controller to adjust the material discharge speed of the mixer truck. The control method can achieve auto-control of the material discharge speed of the mixer truck and also can match the material discharge speed of the mixer truck with the pumping speed of the pump truck, thereby reducing labor intensity and increasing work efficiency. The invention also discloses the pumping mechanical system.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a control method of a pumping mechanical system and a pumping mechanical system. Background technique [0002] The hydraulic oil pump configured on the traditional concrete mixer truck is a mechanical oil pump, and the mixer truck control system uses a mechanical linkage structure, which mainly controls the oil pump through the joystick and mechanical transmission to control the pull rod to realize the forward, reverse and neutral stop of the oil pump. Function, and change the speed of the engine through the throttle control lever, so as to complete the functions of feeding, stirring, stopping and discharging. The principle block diagram of the traditional mechanical control system of the mixer truck to manually control the discharging speed is as follows: figure 1 shown. [0003] Therefore, the operator needs to manipulate the handle by visually checking the mater...
