Double spiral blades are installed on the inner wall of the truck mixing drum, which rotate in a positive direction to mix the incoming concrete; Reverse rotation, driven by spiral blades, concrete is discharged from the discharge port. The safety operation specifications for self loading mixer trucks are as follows: 1. Unloading at the construction site

自上料搅拌车搅拌筒内壁上设置双螺旋形叶片，正向旋转为进料混凝土搅拌；反向旋转，在螺旋叶片的推动下混凝土由出料口出料。自上料搅拌车操作规范介绍如下：

Double spiral blades are installed on the inner wall of the mixing drum of the self feeding mixer truck, which rotate in a positive direction to mix the feeding concrete; Reverse rotation, driven by spiral blades, concrete is discharged from the discharge port. The safety operation specifications for self feeding mixer trucks are introduced as follows:

在施工现场卸料完毕后，应立即用自上料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。

After the unloading at the construction site is completed, the inlet and outlet chutes of the hopper should be immediately flushed with the hose accompanying the self loading mixer truck to remove sludge and concrete adhering to various parts of the vehicle body. On the way back to the mixing station, 150-200L of water should be injected into the mixing drum to clean the concrete residue adhered to the drum wall and blades.

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，以保障筒内清洁。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。

After the end of each day's work, the driver should be responsible for injecting clean water into the mixing drum and rotating it at high speed (14-18 rpm) for 5-10 minutes, then draining the water to ensure cleanliness inside the drum. When cleaning various parts of the mixing drum with high-pressure water, attention should be paid to avoiding parts such as instruments and control rods. The distance between the pressure water nozzle and the painted surface of the vehicle body shall not be less than 40 centimeters.

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，需先关闭自上料搅拌车发动机，使搅拌筒完全停止转动。在机修人员进入筒内工作期间，应该保障拌筒内通风良好，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，操作人员应该有良好的绝缘保护。

When removing dirt and residual concrete debris inside and outside the mixing drum, as well as when maintenance personnel enter the drum for maintenance and welding operations, it is necessary to first turn off the engine of the self feeding mixing truck to completely stop the mixing drum from rotating. During the period when maintenance personnel enter the mixing drum for work, they should ensure good ventilation, fresh air, no natural gases or harmful dust, and sufficient oxygen supply inside the mixing drum. When using electric tools inside the cylinder, operators should have good insulation protection.

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自动，工作人员如何规范操作自上料搅拌车以免发生事故。

During work, it is not allowed to extend your hands into the rotating mixing drum. It is strictly prohibited to extend your hands into the connection part of the main discharge chute and the extended discharge chute automatically. How can staff operate the self loading mixing truck in a standardized manner to avoid accidents.
