In addition to regular maintenance, concrete mixer trucks also need to pay attention to many details during daily use, such as daily cleaning. Due to the certain fluidity of the concrete itself, spattering is common in the process of receiving the material. Seriously, there may be a phenomenon of concrete overflow, and the concrete body will retain concrete more or less. During the transportation process, the stains adhering to the surface of the light truck body with the vibration of the road surface will drip on the road surface, causing road surface pollution. Even if it is not dripped, the concrete itself becomes dehydrated and hardens, and stubborn concrete stains are formed on the vehicle body, making it difficult to clean. How to clean the concrete mixer is described below.
It consists of automobile chassis, mixing drum, transmission system, water supply device, full power power take-off, front and rear brackets of mixer drum, reducer, hydraulic transmission system, feeding and discharging system, and operating mechanism.
Mixing medium truck consists of Class II chassis, transmission system, hydraulic system, frame, mixing tank, feeding and discharging device, water supply system, control system, ladder and other parts. The front end of the mixing tank is connected with the reducer and installed on the front end of the rack. The rear end is supported by two rollers mounted on the back of the rack through the raceway.
The power is output by the full power power power take-off of class II chassis and transmitted to the hydraulic pump through the transmission shaft. The hydraulic energy generated by the hydraulic pump is transmitted to the hydraulic motor through the oil pipe. The hydraulic motor converts the hydraulic energy into kinetic energy and transmits it to the mixing tank through the reducer to reduce the speed and increase the torque. By adjusting the angle of the servo handle of the hydraulic pump, the forward and reverse rotation of the mixing tank and the speed are realized, to achieve concrete loading, mixing, discharging and other operations.
Since concrete will solidify into hard blocks in a short time and it is corrosive to steel and paint, it is necessary to clean the concrete adhered to the concrete storage tank and the inlet and outlet after each use of the concrete storage tank.
(1)Flush the feed port with water before each loading to keep the feed port wet during loading.
(2)Filling the washing water tank that is included with the vehicle with water at the same time as loading.
(3)After loading, wash the feed port and clean the residual concrete near the feed port.
(4)After unloading at the construction site, wash the discharge chute, and then add 30-40 l of cleaning water to the concrete storage tank. Keep the concrete storage tank rotating slowly while the heavy truck is returning.
(5)Remember to let go of the sewage in the concrete storage tank before the next loading.
(6)At the end of each day, thoroughly clean the concrete storage tank and around the inlet and outlet to ensure that there is no cement and concrete caking.
If the above work is not carried out carefully once, it will bring great trouble to the future work.
Concrete caking or solidification in the tank will cause great damage to the mini truck. Only when the normal cleaning work is done well, the service life of the cement mixer truck can be extended.
