After the concrete mixer is used for a long time with high strength, there will be damage to its parts. It is necessary to do a good job in maintenance. At the same time, there will be a lot of adverse dirt that needs to be dealt with in time. When cleaning the mixer and its wear-resistant parts, it is also necessary to pay attention to the methods.

一、要定期进行保养规程所规定项目的维护、保养作业，如清洗、润滑、加油等。

1、 It is necessary to regularly carry out the maintenance of the items specified in the maintenance procedures, such as cleaning, lubrication, refueling, etc.

二、混凝土搅拌机开动前要先检查各控制器是否良好，停工后要用水和石子倒入搅拌筒内10-15分钟进行清洗，再将水和石子清洗出。操作人员如须进入搅拌筒内清洗时，除切断电源和卸下熔断器外，并须锁好开关箱。

2、 Before the concrete mixer starts, check whether the controllers are in good condition. After the shutdown, pour water and stones into the mixing drum for 10-15 minutes for cleaning, and then wash the water and stones out. If the operator needs to enter the mixing drum for cleaning, he should not only cut off the power supply and remove the fuse, but also lock the switch box.
                

三、禁止用大锤敲打的方法清扫积存在混凝土搅拌机筒内的混凝土，只能用凿子清扫。

3、 It is forbidden to use the method of hammering to clean the concrete accumulated in the concrete mixer barrel, but only with chisel.

四、在严寒季节，工作完毕后应用水清洗搅拌机滚筒并将水泵、水箱、水管内积水放净，以免水泵、水箱、水管等冻坏。

4、 In the severe cold season, after the work, the mixer drum should be cleaned with water, and the water in the water pump, water tank and water pipe should be drained to avoid freezing damage of the water pump, water tank and water pipe.

不要只注意混凝土搅拌机和搅拌机耐磨配件的维护工作，而忽略了其清洗过程，否则时间久了日积月累会对搅拌机各方面造成较大的副作用。

Do not only pay attention to the maintenance of concrete mixer and its wear-resistant parts, but also ignore the cleaning process, otherwise it will cause great side effects on all aspects of the mixer over time.
