Double-spiral blades are arranged on the inner wall of the mixing drum, and the forward rotation is used for feeding and concrete mixing; Reverse rotation, driven by the spiral blade, the concrete is discharged from the outlet. The safety operation specifications of self-feeding mixer are as follows:

在施工現(xiàn)場卸料自上料攪拌車攪拌筒內(nèi)壁上設(shè)置雙螺旋形葉片，正向旋轉(zhuǎn)為進料、混凝土攪拌；反向旋轉(zhuǎn)，在螺旋葉片的推動下、混凝土由出料口出料。自上料攪拌車安全操作規(guī)范介紹如下：

Double-spiral blades are set on the inner wall of the mixing drum of the unloading and self-loading mixer at the construction site, and the forward rotation is feeding and concrete mixing; Reverse rotation, driven by the spiral blade, the concrete is discharged from the outlet. The safety operation specifications of self-feeding mixer are as follows:

1、施工現(xiàn)場卸料完畢后，應(yīng)立即用自上料攪拌車隨帶的軟管沖洗進料斗、出料斗、卸料溜槽等處，清除粘附在車身各處的污泥及混凝土。在返回攪拌站的途中，應(yīng)向攪拌筒內(nèi)注150---200L水以清洗筒壁及葉片粘結(jié)的混凝土殘渣。

1. After unloading at the construction site, immediately flush the inlet hopper, outlet hopper, discharge chute and other places with the hose attached to the self-loading mixer truck to remove the sludge and concrete adhering to the vehicle body. On the way back to the mixing station, 150-200L water shall be injected into the mixing drum to clean the concrete residue bonded to the drum wall and blades.

2、每天工作結(jié)束后，司機應(yīng)負責(zé)向攪拌筒內(nèi)注入清水并高速（14—18轉(zhuǎn)/分）旋轉(zhuǎn)5—10分鐘，然后將水排去，以保障筒內(nèi)清潔。用高壓水清洗攪拌筒各個部分時，應(yīng)注意避開儀表及操縱桿等部位。壓力水噴嘴與車身油漆表面間的距離不得小于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 using high-pressure water to clean all parts of the mixing drum, attention should be paid to avoiding the parts such as instruments and control rods. The distance between the pressure water nozzle and the body paint surface shall not be less than 40 cm.

3、清除攪拌筒內(nèi)外積污及殘存的混凝土渣塊時，以及在機修人員進入筒內(nèi)進行檢修和焊補作業(yè)時，需先關(guān)閉自上料攪拌車發(fā)動機，使攪拌筒完全停止轉(zhuǎn)動。在機修人員進入筒內(nèi)工作期間，應(yīng)該保障拌筒內(nèi)通風(fēng)良好，空氣新鮮，無可然氣體及有害灰塵，氧氣供應(yīng)充足。在筒內(nèi)使用電動工具操作時，操作人員應(yīng)該有良好的絕緣保護。

3. When removing the dirt and residual concrete slag inside and outside the mixing drum, as well as when the mechanical maintenance personnel enter the drum for maintenance and welding repair operations, it is necessary to shut down the engine of the self-feeding mixing truck to completely stop the mixing drum. During the period when the machine maintenance personnel enter the mixing drum for work, they should ensure that the mixing drum is well ventilated, fresh air, free of natural gas and harmful dust, and sufficient oxygen supply. When using electric tools in the cylinder, the operator should have good insulation protection.

4、工作時，不得將手伸入旋轉(zhuǎn)的攪拌筒內(nèi)，嚴禁將手伸入主卸料溜槽和加長卸料溜槽的連接部位自動，工作人員如何規(guī)范操作自上料攪拌車以免發(fā)生事故。

4. When working, do not put your hands into the rotating mixing drum. Do not put your hands into the connection part of the main discharge chute and the extended discharge chute automatically. How can the staff operate the self-feeding mixing truck to avoid accidents.
