The mixer truck host system shall be cleaned at least once in a working cycle. After the daily production activities, the main engine information of the mixer truck shall be cleaned comprehensively. The method is: during the cleaning service, put water and a little stone into the mixer main engine and mix for 5 ~ 10min. After cleaning, all the material management in the mixer shall be effectively removed without ponding and accumulation; After shutdown, wash the and pipes to remove dust and adhered concrete inside and outside the mixing tank. Generally, in this case, about 150 ~ 180kg water is added between the main machines of JS1000 mixing equipment. The main machines of other product models can analyze the increase or decrease according to this, or provide their own high-pressure water gun or clean the data.

在冲洗搅拌主机料门时，应避免上部冲洗下的积料形成异物卡滞料门现象。搅拌过程中，若混凝土运输车较长时间没有到位(超过20～30min，尤其在夏季)，应加水对搅拌机进行简易清洗。

When flushing the material door of the mixing machine, avoid the accumulation of material under the upper flushing to form the phenomenon of foreign matter blocking the material door. During mixing, if the concrete truck is not in place for a long time (more than 20 ~ 30min, especially in summer), add water to simply clean the mixer.

搅拌车设备正常生产期间，要定期检查搅拌筒内及搅拌轴上混凝土的凝固情况，如有凝结应及时按要求进行人工铲除。人工清理搅拌筒前，必须切断电源、气路，放净余气、锁好控制室;人工清理搅拌筒时，严禁猛烈敲击搅拌轴、搅拌臂及搅拌叶片。

During the normal production of mixer truck equipment, the solidification of concrete in the mixing drum and on the mixing shaft shall be checked regularly. If there is condensation, it shall be removed manually in time as required. Before manually cleaning the mixing drum, the power supply and gas circuit must be cut off, the residual gas must be discharged, and the control room must be locked; When manually cleaning the mixing drum, it is strictly prohibited to knock the mixing shaft, mixing arm and mixing blade violently.

自动上料搅拌车用冲洗充电门，上部冲洗避免夹在充电门的现象形成的异物积累的材料时的搅拌主机设备。混合过程中，如果不再有在现浇混凝土卡车（超过20?30分钟，尤其是夏天），水应加入搅拌机，便于清洗。

The automatic charging mixer is used to flush the charging door, and the upper part is used to flush the mixing host equipment to avoid the accumulation of foreign materials caused by the phenomenon of being caught in the charging door. During the mixing process, if there are no more trucks in the cast-in-situ concrete (more than 20? 30 minutes, especially in summer), the water shall be added to the mixer for easy cleaning.
