自上料水泥攪拌機攪拌筒內壁上設置雙螺旋形葉片，正向旋轉為進料、混凝土攪拌；反向旋轉，在螺旋葉片的推動下、混凝土由出料口出料。自上料水泥攪拌機操作規范介紹如下：
Double spiral blades are set on the inner wall of the mixing drum of the feeding cement mixer, which rotate in the positive direction for feeding and concrete mixing; In reverse rotation, the concrete is discharged from the discharge port under the push of the spiral blade. The operation specification of self feeding cement mixer is introduced as follows:
1、在施工現場卸料完畢后，應立即用自上料水泥攪拌機隨帶的軟管沖洗進料斗、出料斗、卸料溜槽等處，清理干凈粘附在車身各處的污泥及混凝土。在返回攪拌站的途中，應向攪拌筒內注150---200L水以清洗筒壁及葉片粘結的混凝土殘渣。
1. After unloading at the construction site, immediately flush the feed hopper, discharge hopper, discharge chute, etc. with the hose attached to the feeding cement mixer, and clean up the sludge and concrete adhered 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 to the drum wall and blades.
2、每天工作結束后，司機應負責向攪拌筒內注入清水并高速（14—18轉/分）旋轉5—10分鐘，然后將水排去，以保障筒內清潔。用高壓水清洗攪拌筒各個部分時，應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 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 instruments, control rods and other parts. The distance between the pressure water nozzle and the paint surface of the vehicle body shall not be less than 40cm.
3、清理干凈攪拌筒內外積污及殘存的混凝土渣塊時，以及在機修人員進入筒內進行檢修和焊補作業時，需先關閉自上料水泥攪拌機發動機，使攪拌筒完全停止轉動。在機修人員進入筒內工作期間，應該保障拌筒內通風良好，空氣新鮮，無可然氣體及有害灰塵，氧氣供應充足。在筒內使用電動工具操作時，操作人員應該有良好的絕緣保護。
3. When cleaning the accumulated dirt and residual concrete residue inside and outside the mixing drum, and when the mechanical maintenance personnel enter the drum for maintenance and welding repair, it is necessary to turn off the self feeding cement mixer engine first to stop the mixing drum completely. During the period when the mechanical maintenance personnel enter the drum for work, they should ensure that the mixing drum has good ventilation, fresh air, no combustible 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，不得將手伸入旋轉的攪拌筒內，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，工作人員如何規范操作自上料水泥攪拌機以免發生事故。
4. When working, do not put your hand into the rotating mixing drum. It is strictly prohibited to put your hand into the connecting part of the main discharge chute and the extended discharge chute. How to standardize the operation of the self feeding cement mixer to avoid accidents.
