小型混凝土搅拌机作为搅拌站中重要的部分，用户在选择时也是很谨慎，但有时候在使用过程中还是摆脱不了会出现故障问题。下面来讲讲小型混凝土搅拌机使用时会出现的6个故障。

As an important part of the mixing plant, small concrete mixers are also very cautious in their selection, but sometimes they can't get rid of the problem of failure during use. Now let's talk about the six faults that will occur when using a small concrete mixer.

1.由于联接螺栓松动衬板不齐造成搅拌叶片、支撑臂衬板松动。

1. The lining plates of mixing blades and support arms are loose due to loose connecting bolts and uneven lining plates.

2.圆锥滚子轴承损坏，造成卷扬减速器嗓声异常。

2. The tapered roller bearing is damaged, causing abnormal noise of the winch reducer.

3.搅拌桶内有石子卡住搅拌叶片导致搅拌电机停止运转。

3. There are stones in the mixing bucket that jam the mixing blade, causing the mixing motor to stop running.

4.搅拌叶片磨损严重，没有及时更换，造成间隙太大，石子卡塞过载，搅拌轴端支承装置阻力太大，电压偏低造成搅拌电机过热。

4. The mixing blade is seriously worn and not replaced in time, resulting in too large gap, stone jam overload, too large resistance of the support device at the end of the mixing shaft, and low voltage, causing overheating of the mixing motor.

5.轨道安装不平行或者点击制动器分离间隙过小，电压偏低，使得卷扬电机过热。

5. The track installation is not parallel, or the clearance of brake release is too small, and the voltage is too low, which makes the winch motor overheat.

6.故障指示灯灭可能是因为料斗上升个限位开关坏了或者是摇臂松动，撞针锈蚀，橡胶护套破损等等。

6. The fault indicator light may be off because the first limit switch for hopper lifting is broken or the rocker arm is loose, the striker is rusted, and the rubber sheath is damaged.

以上故障常用的排除方法有：

Common troubleshooting methods for the above faults are:

1.可以在使用前日常检查时紧固联结螺栓调平衬板。2.更换轴承。3.排除搅拌叶片与陈衬板间卡住的石子。4.更换叶片，调好间隙；在搅拌支承装置加注润滑脂。5.调整轨道平行度，调整电机制动分离间隙。6.修复或更换新的限位开关。

1. The coupling bolts can be fastened to level the lining plate during daily inspection before use. 2. Replace the bearing. 3. Remove the stones stuck between the mixing blade and the old lining plate. 4. Replace the blade and adjust the clearance; Add lubricating grease to the mixing support device. 5. Adjust the rail parallelism and the motor brake separation clearance. 6. Repair or replace the limit switch with a new one.
