Mixing truck is a special truck used to transport concrete for construction; Because of its appearance, it is also often called the field snail car, olive car. These trucks are equipped with cylindric mixing tanks to carry the mixed concrete. Concrete mixing transport vehicle by the car chassis and concrete mixing transport special device. The concrete mixing transport vehicles produced in our country use more than two kinds of general chassis provided by vehicle manufacturers. Its special mechanism mainly includes the force retractor, stirring cylinder before and after the support, reducer, hydraulic system, mixing cylinder, operating mechanism, cleaning system, etc. The working principle is that the power of the car chassis is taken out by the force device, and the variable pump of the hydraulic system is driven, and the mechanical energy is converted into hydraulic energy to the quantitative motor, and the motor is driven by the reducer, and the mixing device is driven by the reducer to mix the concrete.
