Self loading concrete mixer is an indispensable existence in our buildings. However, because 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:
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. Wash the feed port with water before each loading to keep the feed port wet 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. Fill the cleaning water tank with water while loading;
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 and 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—40L；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 30-40l of cleaning water to the concrete storage tank; Keep the concrete storage tank rotating forward and slowly 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 storage 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，保证不粘有水泥及混凝土结块。
6. 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.
自上料式混凝土搅拌车清洗维护的要点介绍，以上这些工作只要一次不认真进行，就会给以后的工作带来很大的麻烦，所以希望大家重视自动上料搅拌车的清洗。
Since the introduction of the key points of cleaning and maintenance of the feeding concrete mixer, if the above work is not carried out carefully once, it will bring great trouble to the future work. Therefore, I hope you will pay attention to the cleaning of the automatic feeding mixer.
