The concrete mixing transport vehicle is composed of an automobile chassis and a special device for concrete mixing transport. The special mechanism mainly includes force extractor, stirring cylinder before and after support, reducer, hydraulic system, stirring cylinder, operating mechanism, cleaning system and so on. The working principle is that the power of the car chassis is taken out by the force taking device, and the variable pump of the hydraulic system is driven, the mechanical energy is converted into hydraulic energy and transmitted to the quantitative motor, the motor drives the reducer, and the reducer drives the mixing device to stir the concrete.
