What should we pay attention to when we clean the mixing drum today? We hope to give you a deeper understanding of the concrete mixer through our introduction:

1、在施工现场卸料完毕后，应立即用搅拌车随带的软管冲洗进料斗、出料斗、卸料溜槽等处，粘附在车身各处的污泥及混凝土。在返回搅拌站的途中，应向搅拌筒内注150---200L水以清洗筒壁及叶片粘结的混凝土残渣。

1. After unloading at the construction site, the hose accompanying the mixer shall be used to wash the feeding hopper, discharging hopper, discharge chute and other places, and the sludge and concrete adhered to the vehicle body shall be removed. On the way back to the mixing plant, 150-200l water shall be injected into the mixing drum to clean the concrete residue stuck on the wall and blades.

2、每天工作结束后，司机应负责向搅拌筒内注入清水并高速(14—18转/分)旋转5—10分钟，然后将水排去，以保证筒内清洁。用高压水清洗搅拌筒各个部分时，应注意避开仪表及操纵杆等部位。压力水喷嘴与车身油漆表面间的距离不得小于40厘米。

2. At the end of each day's work, the driver shall be responsible for injecting clean water into the mixing drum and rotating it at high speed (14-18 RPM) for 5-10 minutes, and then draining the water to ensure the cleanness of the drum. When cleaning all parts of the mixing drum with high-pressure water, pay attention to avoid the instrument, control lever and other parts. The distance between the pressure water nozzle and the body paint surface shall not be less than 40 cm.

3、搅拌筒内外积污及残存的混凝土渣块时，以及在机修人员进入筒内进行检修和焊补作业时，需先关闭汽车发动机，使搅拌筒完全停止转动。在机修人员进入筒内工作期间，必须保证拌筒内通风良好，空气新鲜，无可然气体及有害灰尘，氧气供应充足。在筒内使用电动工具操作时，操作人员必须有良好的绝缘保护。

3. When removing the accumulated dirt and residual concrete slag inside and outside the mixing drum, and when the mechanic enters the drum for maintenance and repair welding, the car engine shall be shut down first to completely stop the mixing drum. During the period when the mechanic enters the mixing drum, he must ensure that the mixing drum is well ventilated, the air is fresh, there is no natural gas and harmful dust, and the oxygen supply is sufficient. When using electric tools to operate in the cylinder, operators must have good insulation protection.

4、工作时，不得将手伸入旋转的搅拌筒内，严禁将手伸入主卸料溜槽和加长卸料溜槽的连接部位搅拌，清洗搅拌筒应该这注意什么？以免发生事故。

4. When working, do not extend your hand into the rotating mixing drum. Do not extend your hand into the connection between the main discharge chute and the extended discharge chute for mixing. What should be paid attention to when cleaning the mixing drum? To avoid accidents.
