自动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。自动上料搅拌车操作规范介绍如下：

Double spiral blades are arranged on the inner wall of the mixing drum of the automatic feeding mixer truck, and the positive rotation is for feeding and concrete mixing; Reverse rotation, the concrete is discharged from the outlet under the push of the spiral blade. The safety operation specifications of automatic feeding mixer are as follows:

1、在施工现场卸料完毕后，应立即用自动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。

1. After unloading at the construction site, the hose attached to the automatic feeding mixer shall be used to flush the feed hopper, discharge hopper, discharge chute, etc., to remove the sludge and concrete adhering to the vehicle body. On the way back to the mixing plant, 150-200L water shall be injected into the mixing drum to clean the concrete residue bonded by the drum 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。

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 for 5-10 minutes at high speed (14-18 rpm), and then draining the water to ensure the cleanness of the drum. When cleaning each part of the mixing drum with high-pressure water, attention should be paid to avoiding instruments, control rods 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，需先关闭自动上料搅拌车发动机，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。

3. When removing the dirt and residual concrete slag inside and outside the mixing drum, and when the machine maintenance personnel enter the drum for maintenance and repair welding, the engine of the automatic feeding mixer shall be shut down first to make the mixing drum stop completely. During the period when the machine maintenance personnel enter the mixing drum to work, they should 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 in the cylinder, the operator 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动上料搅拌车以免发生事故。希望以上分享能够帮助大家更好的使用设备，如有问题欢迎大家在线咨询http://www.jfhntjbj.com客服。
