（1）喂料装置的设计不合理。 如果水泥和粉煤灰进料口的位置和方向不合理，则大部分粉末放在轴上，这样粘接在轴上形成“抱抱”现象;

(1) The design of feeding device is unreasonable. If the position and direction of cement and fly ash inlet are not reasonable, most of the powder will be put on the shaft, which will form "hugging" phenomenon;

（2）冲洗点和冲洗方向的位置不正确，或冲洗压力太低。 当冲洗水箱时，粘附在搅拌装置上的混凝土不会被冲洗掉，形成“拥抱”现象;

(2) The position of flushing point and direction is incorrect, or the flushing pressure is too low. When the water tank is flushed, the concrete adhered to the mixing device will not be washed away, forming a "hug" phenomenon;

（3）搅拌筒的体积利用率不合理，体积利用率太小，搅拌轴暴露在混凝土上，一部分附着在上部的混凝土不会搅拌， 在轴上凝固形成“抱轴”现象。

(3) The volume utilization ratio of the mixing drum is unreasonable, the volume utilization ratio is too small, the mixing shaft is exposed on the concrete, part of the concrete attached to the upper part will not be stirred, and the phenomenon of "holding shaft" is formed on the shaft.

（4）靠近搅拌轴的搅拌臂的速度太低。

(4) The speed of the mixing arm near the mixing shaft is too low.
            

搅拌机主机“保持轴”的方案：

The solution of mixer host "holding shaft"

（1）在进料装置的设计中，水泥和粉煤灰进料口位置位于两个搅拌轴之间，切割角度沿搅拌器的轴向。

(1) In the design of the feeding device, the cement and fly ash feeding port is located between the two mixing shafts, and the cutting angle is along the axial direction of the mixer.

（2）在混合机的制造过程中，应确保喷水装置的安装焊接位置，以达到冲洗点的正确位置和冲洗方向。 在搅拌装置的供水系统的设计过程中，确保冲洗的分压的可靠性。 可以增加用于冲洗的特殊压力泵或使用高水箱;

(2) In the manufacturing process of the mixer, the installation and welding position of the sprinkler should be ensured to achieve the correct position and direction of the flushing point. In the design process of water supply system of mixing device, the reliability of partial pressure of flushing is ensured. Special pressure pump for flushing or high water tank can be added;

（3）设备卸载和卸载后，设备操作人员应及时清洗并冲洗油箱，以确保拆除粘附的混凝土。 设备操作人员应定期检查计量系统中计量料斗的连接和关闭紧度，注意是否有泄漏，如果是，请及时。

(3) After the equipment is unloaded and unloaded, the equipment operator shall clean and flush the oil tank in time to ensure the removal of the adhered concrete. Equipment operators should regularly check the connection and closing tightness of the metering hopper in the metering system, and pay attention to whether there is leakage. If so, please remove it in time.
