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．每次裝料前用水衝洗進料口，使進料口在裝料時保持濕潤；
1. Wash the feed port with water before each loading to keep the feed port wet during loading;
2．在裝料的同時向隨車自帶的清洗用水水箱中注滿水；
2. Fill the cleaning water tank with water while loading;
3．裝料後衝洗進料口，洗淨進料口附近殘留的混凝土；
3. After loading, wash the inlet and clean the residual concrete near the inlet;
4．到工地卸料後，衝洗出料槽，然後向混凝土貯罐內加清洗用水30—40L；在車輛回程時保持混凝土貯罐正向慢速轉動；
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．下次裝料前切記放掉混凝土貯罐內的汙水；
5. Remember to discharge the sewage in the concrete storage tank before the next loading;
6．每天收工時徹底清洗混凝土貯罐及進出料口周圍，保證不粘有水泥及混凝土結塊。
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.
自上料式混凝土攪拌車清洗維護的要點介紹，以上這些工作隻要一次不認真進行，就會給以後的工作帶來很大的麻煩，所以希望大家重視自動上料攪拌車的清洗。
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.
