Concrete mixers are very common and can be seen on many construction sites. For the construction of concrete processing, the fuselage should be firmly installed before use, and then tested after installation. Make sure that it can be put into normal operation after installation. The concrete mixer needs to be cleaned and maintained after use. If it is not cleaned for a long time, the concrete will solidify. The following small series will give you an introduction to the operation of concrete mixer need to pay attention to what? And how to clean the concrete mixer after use?

　　一、混凝土搅拌机操作注意事项

　　1、 Precautions for concrete mixer operation

　　1、 搅拌机机身必须安装平稳牢固。

　　1. The mixer body must be installed stably and firmly.

　　2、作业前应检查离合器和制动器是否灵活可靠，钢丝绳有否断丝损坏。防护装置是否齐全可靠，并进行试运转。

　　2. Before operation, check whether the clutch and brake are flexible and reliable, and whether the wire rope is broken or damaged. Whether the protective device is complete and reliable, and the test run is carried out.

　　3、禁止超负荷使用。机械运转中禁止用手或其他物体伸入拌和筒内去拨弄、清洗和修理等工作。

　　3. Overloading is prohibited. It is forbidden to use hands or other objects to poke, clean and repair the mixing drum during the operation of the machine.
                   

　　4、进料斗升起时，严禁任何人在料斗下通过或停留。

　　4. When the feeding hopper is raised, no one is allowed to pass or stay under the hopper.

　　5、料斗应缓缓放下，以免下落速度太快，损坏机件或发生故障。进料斗未停稳前，不得进料。

　　5. The hopper should be put down slowly, so as to avoid falling too fast, damaging the machine parts or failure. Do not feed until the feeding hopper stops stably.

　　6、当搅拌机满负荷运转中突然停电或发生故障时，应用人力将拌和筒内存料清出，然后进行检查或修理。

　　6. In case of sudden power failure or failure during the full load operation of the mixer, the material stored in the mixing drum shall be cleared out by manpower, and then inspection or repair shall be carried out.

　　7、操作人员如必须进入拌和筒内进行清洗或检修，应严格控制电源，以防发生意外事故。

　　7. If the operator must enter the mixing drum for cleaning or maintenance, the power supply should be strictly controlled to prevent accidents.

　　8、在开车清洗时，禁止操作人员爬到进料斗，防止脚碰离合器后，进料斗提升伤人。

　　8. When cleaning the car, it is forbidden for the operator to climb to the feeding hopper to prevent personal injury caused by lifting the feed hopper after the foot touches the clutch.                 

　　二、混凝土搅拌机使用后如何清洗

　　2、 How to clean concrete mixer after use

　　1、混凝土搅拌机在使用前要先检查各个器件能否正常使用，停工后把一些水和石子放入搅拌桶内开启电源进行清理15~20分钟左右，再将水和石子清理出。

　　1. Before using the concrete mixer, check whether all devices can work normally. After shutdown, put some water and stones into the mixing bucket, turn on the power supply for cleaning for about 15 ~ 20 minutes, and then clean the water and stones.

　　2、混凝土搅拌机就像汽车一样，也需要定期的保养维护。

　　2. Like a car, concrete mixer also needs regular maintenance.

　　3、切记不能用大锤敲击的方式清理存在混凝土搅拌机筒内已经凝固的混凝土，这样会损坏机器。

　　3. Remember not to clean the solidified concrete in the concrete mixer barrel by hammering, which will damage the machine.

　　4、在冬季使用时，要注意工作完毕后用水清洗滚筒并将水泵，水箱。

　　4. When using in winter, it is necessary to clean the drum with water and pump and water tank after work.

　　5、每次使用完之后要及时清洗，否则等混凝土凝固之后就会很难清洗，费时又费力。

　　5. After each use, it should be cleaned in time, otherwise it will be difficult to clean after the concrete is set, which is time-consuming and laborious.
