The mixer truck is a special truck for transporting concrete for construction. It is generally used on the construction site. Because of the particularity of concrete, the mixing drum will always carry out mixing during the transportation of the mixer truck to avoid concrete solidification failure. After transportation, the interior must be washed with water in time, so as to ensure the cleanness in the drum and the occupation of space by residual cement.
The concrete mixer truck is composed of an automobile chassis and a customized mixing device system, which is mainly composed of water injection system, loading, feeding and discharging system, power take-off, unloading tank and other systems. The working principle of the mixer truck is to take out the power of the chassis through the power take-off, successively transmit it to the hydraulic variable system, change the mechanical energy into hydraulic energy, and then transmit it to the quantitative motor, Then, the motor drives it to the reducer, and the reducer finally drives the mixing device to mix the concrete.
Concrete mixer truck is also divided into wet material type, dry material type and semi dry material type, which is divided according to water content.
The mixer truck must be operated after training, so as to work efficiently.
As for the maintenance of mixer truck, especially the driving device, it is mainly composed of power take-off, hydraulic motor, control valve, cardan shaft, hydraulic pump, hydraulic oil tank and cooling device. The failure of the driving device will lead to the scrapping of concrete in the truck, and even the scrapping of the vehicle. We must pay attention to the maintenance of the driving device, such as Cardan rotation (to ensure the constant availability of lubricating oil), Cleaning of hydraulic oil (if sediment enters, it must be replaced immediately) and normal operation of hydraulic oil cooling device (ensure normal operation of radiator).
