In the construction industry, the small concrete mixer is often used as a transport vehicle. In terms of normal maintenance, the automatic loading mixer truck should pay attention to cleaning and maintenance. Some careless people may ignore these details, and the results will be very satisfactory. But if we just pay attention to these, it will greatly extend the life of the automatic feeding mixer.

每天必须要做的事情如下：

The things you have to do every day are as follows:

1、每次装料前用水冲洗进料口，使进料口在装料时保持湿润；

1. Flush the feed port with water before each loading to keep the feeding port moist during loading;

2、在装料的同时向随车自带的清洗用水水箱中注满水；

2. At the same time of loading, fill the water tank with water;

3、装料后冲洗进料口，洗净进料口附近残留的混凝土；

3. After loading, wash the inlet to clean the residual concrete near the inlet;

4、到工地卸料后，冲洗出料槽，然后向混凝土贮罐内加清洗用水30—40 L；在车辆回程时保持混凝土贮罐正向慢速转动；

4. After unloading at the construction site, wash the discharge tank, and then add 30-40 l of cleaning water into the concrete storage tank; keep the concrete storage tank in forward and slow rotation when the vehicle returns;

5、下次装料前切记放掉混凝土贮罐内的污水；

5. Remember to discharge the sewage in the concrete tank before the next loading;

6、每天收工时彻底清洗混凝土贮罐及进出料口周围自动，自动上料搅拌车的清洗要点保证不粘有水泥及混凝土结块。

6. At the end of each day, the concrete storage tank and the surrounding area of the material inlet and outlet shall be thoroughly cleaned. The cleaning points of the automatic feeding mixer truck shall ensure that there is no cement and concrete caking.

因为混凝土会在短时间内凝结成硬块，且对钢材和油漆有一定的腐蚀性，所以每次运用混凝土贮罐后，洗净粘附在混凝土贮罐及进出料口上的混凝土是每日维护有必要细心进行的工作。其间包含：每次装料前用水冲刷进料口，使进料口在装料时坚持湿润；在装料的一起向随车自带的清洗用水水箱中注满水；装料后冲刷进料口，洗净进料口邻近残留的混凝土；到工地卸料后，冲刷出料槽，然后向混凝土贮罐内加清洗用水30—40L；在车辆回程时坚持混凝土贮罐正向慢速翻滚。

Because the concrete will condense into a hard block in a short time, and has a certain degree of corrosivity to steel and paint, so it is necessary to carry out daily maintenance to clean the concrete adhered to the concrete storage tank and the inlet and outlet after each use of the concrete tank. It includes: flushing the inlet with water before each loading to keep the inlet wet during loading; filling the water tank with water during loading; flushing the inlet after loading to clean the residual concrete near the inlet; after unloading at the construction site, wash the discharge tank, and then add 30-40l cleaning water into the concrete storage tank; adhere to the principle of filling the water tank with water for cleaning when the vehicle returns The concrete tank is rolling slowly forward.

这些工作只需一次不细心进行，就会给今后的工作带来很大的费事。电气控制系统是自动上料搅拌车的神经，是泵车正常工作的首要保证，该系统的构成凌乱，缺点定位也相对困难。

If these works are not carried out carefully once, they will bring great trouble to the future work. The electrical control system is the nerve center of the automatic feeding mixer and the primary guarantee for the normal operation of the pump truck. The composition of the system is disorderly, and the positioning of its shortcomings is relatively difficult.
