Concrete mixer supply system refers to the accumulation and upgrading of stone, sand, cement, water and other materials into commercial concrete. Sand and stone lifting, using cantilever shovel method, as well as loader, plus belt conveyor. The cement is blown into the bulk cement silo with compressed air and sent to the cement scale by screw conveyor. The water used for mixing is usually supplied by a pump.

混凝土搅拌机总供应系统由三部分组成：收集箱，聚合计量桶和骨料输送。

The total supply system of concrete mixer consists of three parts: collecting box, aggregate metering bucket and aggregate conveying.

集料运输：有两种运输料斗和输送带的方式。 料斗输送的优势是占地面积小，结构简单。 带式输送机具有输送距离大，效率高，故障率低的优势。 带式输送机主要适用于带有集料储罐的搅拌站，提高了搅拌站的生产率。

Aggregate transportation: there are two ways to transport hopper and conveyor belt. The advantages of the hopper are simple structure and small area. Belt conveyor has the advantages of long conveying distance, high efficiency and low failure rate. Belt conveyor is mainly suitable for mixing station with aggregate storage tank, which improves the productivity of mixing station.

混凝土搅拌机供应系统常见问题：

Common problems of concrete mixer supply system:

1.料斗偏向或卡住。 这主要是由于两个凸起的芯或芯的跳线长度不一致。 可以通过调节灯芯的长度，调节灵敏度的下限和调节防跳装置来。

1. The hopper is deflected or jammed. This is mainly due to the inconsistency of the jumper length of two protruding cores or cores. It can be solved by adjusting the length of the wick, adjusting the lower limit of sensitivity and adjusting the anti bounce device.

2.卸下料斗后，无法控制跌落。 这主要是由于旅行开关未能修理或更换。

2. After unloading the hopper, the dropping cannot be controlled. This is mainly due to the failure to repair or replace the travel switch.

3.绞车过热主要是由于制动装置间隙不当造成的。 发现后立即调整电机制动器。

3. The overheating of winch is mainly caused by improper clearance of brake device. Adjust the motor brake immediately after discovery.

4.配料机的进料门工作不正常。 主要原因是门和门框之间的间隙太大或门变形。 门被沙子和砾石挡住了。 纠正材料门或更换材料门或橡胶板。

4. The feeding door of batching machine is not working normally. The main reason is that the gap between the door and the door frame is too large or the door is deformed. The door was blocked by sand and gravel. Correct material door or replace material door or rubber plate.

5，气缸力小，需要检查气源压力或修缸。

5. The cylinder force is small, so it is necessary to check the air supply pressure or repair the cylinder.
