1、 The reason why the mixing shaft of self feeding mixing truck stops rotating: in the production process, it is normal for the mixing shaft of concrete self feeding mixing truck to stop rotating or rotate a little slowly. If this happens, stop the machine first and check to see if there are the following three situations.

1、电机传动皮带有没有出现松动的情况？自拌混凝土搅拌车电机传动皮带过松也能导致商品混凝土拌合机搅拌轴转动缓慢或者停止转动，电机传动皮带过松，导致传递的动力不足。

1. Is the motor drive belt loose? Too loose motor drive belt of self mixing concrete mixer can also lead to slow rotation or stop rotation of mixing shaft of commercial concrete mixer. Too loose motor drive belt leads to insufficient power transmission.

2、有没有严重超载？自拌混凝土搅拌车搅拌轴如果超过正常工作负荷，会使搅拌轴转动缓慢，若负荷过大，就会导致搅拌轴停转或者是搅拌轴弯曲。

2. Is there any serious overload? If the mixing shaft of self mixing concrete mixer exceeds the normal working load, it will make the mixing shaft rotate slowly. If the load is too large, it will cause the mixing shaft to stop or bend.

3、搅拌叶片或侧叶片与筒体内壁间有没有大的异物？出现这种情况也会使混凝土自动上料搅拌车搅拌轴停止转动或转动缓慢。搅拌叶片或侧叶片与罐内壁间有较大的异物也会导致搅拌轴停转，之所以能卡存异物，就是由于搅拌叶片或侧叶片与罐内壁间隙过大造成的，尤其是石子。

3. Is there any big foreign matter between the mixing blade or side blade and the inner wall of the cylinder? In this case, the mixing shaft of automatic concrete feeding mixer will stop rotating or rotate slowly. There are large foreign matters between the mixing blade or side blade and the inner wall of the tank, which will also cause the mixing shaft to stop running. The reason why the foreign matters can be stuck is that the gap between the mixing blade or side blade and the inner wall of the tank is too large, especially the stones.

二、自上料搅拌车搅拌轴停转的方法：

2、 The solution to stop the mixing shaft of self feeding mixer is as follows:

1、混凝土自动上料搅拌车电机传动皮带过松的情况，只需停机后调整混凝土搅拌机电机传动皮带的张紧度即可。

1. When the motor driving belt of the concrete automatic feeding mixer is too loose, the tension of the driving belt of the concrete mixer should be adjusted after stopping.

2、混凝土自动上料搅拌车超载而造成搅拌轴停转，只需调整进料量，卸出多余的物料，降低搅拌轴转动负荷即可。

2. If the overload of the automatic concrete feeding mixer causes the mixing shaft to stop, just adjust the feeding amount, unload the surplus materials and reduce the rotating load of the mixing shaft.

3、侧叶片与关内壁卡滞物料时，在搅拌轴停转前往往会有尖锐刺耳的摩擦声，出现这种情况时，需立即停机检查，人工排除异物，重新调整混凝土自动上料搅拌车搅拌叶片或侧叶片与罐内壁间的间隙，有必要时可以用水先清洗下。

3. When the material is stuck between the side blade and the inner wall, there will be sharp and harsh friction sound before the mixing shaft stops. In this case, it is necessary to stop the machine immediately for inspection, remove the foreign matter manually, readjust the gap between the mixing blade or side blade of the automatic concrete feeding mixer and the inner wall of the tank, and clean it with water if necessary.
