Concrete mixer is a kind of high efficiency machine which can mix hard, dry, plastic, popular and all kinds of mortar in large, medium and small prefabricated loose parts factory, water conservancy, factory, wharf industrial and civil construction engineering. In the production process, it is normal for the mixing shaft of concrete mixer to roll intermittently or a little slowly. If this is the case, it is the first time to stop the machine for inspection To see if there are the following three situations.

一、混凝土搅拌机有没有严峻超载？

1、 Is the concrete mixer severely overloaded?

混凝土搅拌机搅拌轴假设逾越正常工作负荷，会使搅拌轴翻滚缓慢，若负荷过大，就会致使搅拌轴停转或者是搅拌轴曲折。

Assuming that the mixing shaft of concrete mixer exceeds the normal working load, the mixing shaft will roll slowly. If the load is too large, the mixing shaft will stop or the mixing shaft will bend.

二、混凝土搅拌机搅拌叶片或侧叶片与筒体内壁间有没有大的异物？

2、 Is there any big foreign matter between mixing blade or side blade of concrete mixer and inner wall of cylinder?

出现这种情况也会使 混凝土搅拌机搅拌轴间断翻滚或翻滚缓慢。搅拌叶片或侧叶片与罐内壁间有较大的异物也会致使搅拌轴停转，之所以能卡存异物，便是因为混凝土搅拌机搅拌叶片或侧叶片与罐内壁空隙过大构成的。尤其是石子

In this case, the mixing shaft of concrete mixer will roll intermittently or 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 foreign matters can be trapped is that the gap between the mixing blade or side blade of the concrete mixer and the inner wall of the tank is too large. Especially stones

三、混凝土搅拌机电机传动皮带有没有出现松动的情况？

3、 Is the motor drive belt of concrete mixer loose?

混凝土搅拌机电机传动皮带过松也能致使混凝土搅拌机搅拌轴翻滚缓慢或者间断翻滚，电机传动皮带过松，致使传递的动力缺乏。

The motor drive belt of concrete mixer is too loose, which can also cause the mixing shaft of concrete mixer to roll slowly or intermittently. The motor drive belt is too loose, which leads to the lack of power transmission.

对于以上三种情况给出以下办法：

For the above three cases, the following solutions are given:

一、混凝土搅拌机超载而构成搅拌轴停转，只需调整进料量，卸出剩余的物料，降低搅拌轴翻滚负荷即可。

1、 When the concrete mixer is overloaded and the mixing shaft stops running, it only needs to adjust the feeding amount, discharge the remaining materials and reduce the rolling load of the mixing shaft.

二、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尖锐的抵触声，出现这种情况时，需当即停机检查，人工打扫异物，从头调整混凝土搅拌机搅拌叶片或侧叶片与罐内壁间的空隙，有必要时可以用水先清洗下。

2、 When the material is stuck between the side blade and the inner wall of the tank, there is often a sharp collision sound before the mixing shaft stops. In this case, it is necessary to stop the machine immediately for inspection, clean the foreign matters manually, and adjust the gap between the mixing blade or the side blade of the concrete mixer and the inner wall of the tank from the beginning. If necessary, it can be cleaned with water first.

三、混凝土搅拌机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。

Three, the concrete mixer motor drive belt loose condition, just stop after adjusting the concrete mixer motor drive belt tension degree can be.
