Since the concrete will solidify into hard blocks in a short time and have certain corrosivity to steel and paint, cleaning the concrete adhered to the concrete storage tank and the inlet and outlet after each use of the concrete storage tank is a daily maintenance work that must be carried out carefully. These include:
a. Wash the feed port with water before each loading to keep the feed port wet during loading;
b. Fill the cleaning water tank with water while loading;
c. Wash the inlet after loading and clean the residual concrete near the inlet;
d. After unloading at the construction site, wash the discharge tank, and then add 30-40l of cleaning water to the concrete storage tank; Keep the concrete storage tank rotating forward and slowly when the vehicle returns;
e. Remember to discharge the sewage in the concrete storage tank before the next loading;
f. Thoroughly clean the concrete storage tank and around the inlet and outlet at the end of each day to ensure that there is no cement and concrete caking. As long as the above work is not carried out seriously once, it will bring great trouble to the future work.
The driving device is used to drive the concrete storage tank to rotate. It is composed of power takeoff, universal shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling device. If this part stops working due to failure, the concrete storage tank will not rotate, which will lead to the scrapping of the concrete in the vehicle, and even the whole tank of concrete will condense in the tank, resulting in the scrapping of the concrete mixing truck. Therefore, whether the driving device is reliable or not is a problem that must be paid great attention to in use.
