Electronic control system for mixing drum of mixing truck

Abstract

The invention belongs to the field of control over mixing trucks and provides an electronic control system for a mixing drum of a mixing truck. The electronic control system for the mixing drum of the mixing truck comprises an indoor control mechanism (1), an outdoor control mechanism (2), an electronic control module (3) and a mechanical fuel pump actuator (4). The indoor control mechanism (1) and the outdoor control mechanism (2) are the same in structure and are each composed of a knob potentiometer, an emergency button and a control panel. The mechanical fuel pump actuator (4) is electrically connected with the electronic control module (3) and connected with a swing arm of a mechanical fuel pump, and a potentiometer installed on the mechanical fuel pump actuator feeds opening signals of the fuel pump back to the electronic control module (3). The electronic control module (3) outputs throttle signals to the signal input end of an engine throttle through a DA converter. The electronic control system can meet control requirements of different occasions, and has the beneficial effects of being easy to arrange and operate, convenient to install and low in labor intensity.

Description

technical field [0001] The invention belongs to the field of mixer truck control, and in particular relates to an electronic control system for a mixer drum of a mixer truck. Background technique [0002] Concrete mixer trucks are the main transportation and mixing tools for concrete in the construction industry. At present, the control methods of mixer truck mixing drums on the market are mainly divided into electronically controlled oil pump type and mechanical oil pump type. The electronically controlled oil pump type mixing vehicles are mainly imported vehicles, with high equipment cost and difficult maintenance; the mechanical oil pump type is mostly controlled by a mechanical hard rod structure or a soft shaft controller structure, which is complicated in structure, difficult in installation and layout, and heavy in operation and long-term. Time operation is likely to cause driver fatigue and cause safety accidents. In addition, when the mixing drum needs to rotate at...

Problems solved by technology

The electronically controlled oil pump type mixing vehicles are mainly imported vehicles, with high equipment cost and difficult maintenance; the mechanical oil pump type is mostly controlled by a mechanical hard rod structure or a soft shaft controller structure, which is complicated in structure, difficult in installation and layout, and heavy in operation and long-term. Time operation is likely to cause driver fatigue and lead to safety accidents

In addition, when the mixing drum needs to rotate at high speed, there may be situations where the opening of the mechanical oil pump is small and the engine throttle is always increased, which will cause a lot of fuel waste and environmental pollution
