Technical Field

The invention relates to a mixer truck, in particular to an electric mixer truck with a fuel oil type single engine.

Background

the cement mixer truck is also called a concrete mixer truck and is mainly used for the transportation work of cement in a concrete mixing plant. The main special accessories of the existing cement mixer comprise a power takeoff, a front support and a rear support of a mixing drum, a speed reducer, a hydraulic system, the mixing drum, an operating mechanism, a cleaning system and the like. The working principle is that the power of the automobile chassis is taken out through the power takeoff, the hydraulic pump of the hydraulic system is driven, mechanical energy is converted into hydraulic energy and transmitted to the hydraulic motor, the motor drives the speed reducer again, the speed reducer drives the stirring system to stir concrete, and the power source of the hydraulic system is derived from the hydraulic pump which is coaxially connected with the main shaft of the engine. When the engine is started, the engine drives the hydraulic pump to work, hydraulic oil is conveyed to the hydraulic motor through the corresponding control valve group, and forward and reverse rotation control can be performed. In order to meet the working requirement, accessories such as an oil tank, a radiator and the like are required to be arranged, and pipelines and the like also need to be replaced regularly. The power of the conventional hydraulic pump is about 55kW, which is about 80 horsepower, and the maximum power required for actually driving the stirring tank to rotate is 27 kW. The power of the engine is generally 330 horsepower, and the proportion of the stirring system is approximately one fourth at most. The hydraulic stirring system is limited by the working principle, and the working efficiency of the hydraulic stirring system is generally lower than 50%. And the stirring tank has long working time and serious fuel oil waste. At present, a mode that an auxiliary engine is erected on a chassis to drive a motor to drive a stirring tank to rotate is adopted to replace hydraulic driving, and the working efficiency is high.

The Chinese patent application publication numbers are: CN106627128A, application publication No. 2017.05.10 discloses a washing and sweeping vehicle auxiliary engine power system and a washing and sweeping vehicle. The auxiliary engine power system of the washing and sweeping vehicle comprises an auxiliary engine and a pneumatic friction type clutch, the pneumatic friction type clutch comprises a driving wheel and a driven wheel, the driving wheel is fixedly mounted on a transmission shaft of the auxiliary engine, the driven wheel is in transmission connection with a water pump of the washing and sweeping vehicle, the auxiliary engine outputs power to the water pump through the pneumatic friction type clutch, the water pump can be in clutching at a speed, in the sweeping operation process, the pneumatic friction type clutch can be operated to be connected and separated without stopping the auxiliary engine to achieve switching between a sweeping mode and a washing and sweeping mode, working efficiency is improved, and misoperation probability of an operator is greatly reduced. Although this application is washing and sweeping vehicle technical field, has also used vice engine to accomplish the sweeping action, do not additionally occupy chassis power, need not use hydraulic drive system, simple structure, work efficiency is high, but, owing to adopted vice engine, vehicle overall structure is complicated, and the facial make-up space seems narrow and small, and each part is put the difficulty, and vehicle overall cost is high.
