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.

混凝土攪拌機總供應系統由三部分組成：收集箱，聚合計量桶和骨料輸送。

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

集料運輸：有兩種運輸料斗和輸送帶的方式。 料斗輸送的優勢是占地面積小，結構簡單。 帶式輸送機具有輸送距離大，效率高，故障率低的優勢。 帶式輸送機主要適用于帶有集料儲罐的攪拌站，提高了攪拌站的生產率。

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.

混凝土攪拌機供應系統常見問題：

Common problems of concrete mixer supply system:

1.料斗偏向或卡住。 這主要是由于兩個凸起的芯或芯的跳線長度不一致。 可以通過調節燈芯的長度，調節靈敏度的下限和調節防跳裝置來。

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，無法控制跌落。 這主要是由于旅行開關未能修理或更換。

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.絞車過熱主要是由于制動裝置間隙不當造成的。 發現后立即調整電機制動器。

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

4.配料機的進料門工作不正常。 主要原因是門和門框之間的間隙太大或門變形。 門被沙子和礫石擋住了。 糾正材料門或更換材料門或橡膠板。

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，氣缸力小，需要檢查氣源壓力或修缸。

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