In the actual operation and use of automatic concrete mixer, material blockage may occur due to some reasons. To a certain extent, it can directly affect the construction efficiency of mixer truck. Please tell me some ways to avoid it.

1.不合理的装卸时间参数

1. Unreasonable handling time parameters

该行业基本上是时间控制的，因为自动进料器无法为料仓配备矫平机。设置时间参数，加载和卸载时间实际上非常容易。初次使用时，请先设置少量时间，然后在每个抽吸位置缓慢增加，并在物料水平达到抽吸释放时间时减去。 1秒是一个合理的时间。排出时间是为了确保排出物料并添加额外的1秒。这有两个优点。一种是材料水平过高而不会严重损坏滤芯。这使某些客户可以使用滤芯两年半。其次，您可以每次清洗材料。关闭进料阀可物料截止阀。材料截止阀会严重损坏频繁运行的密封圈，该密封圈每分钟打开和关闭56次。

The industry is basically time controlled because automatic feeders cannot be equipped with levelers for bins. Setting time parameters, loading and unloading time is actually very easy. For initial use, set a small amount of time, then slowly increase at each suction position, and subtract when the material level reaches the suction release time. One second is a reasonable time. The discharge time is to ensure that the material is discharged and an additional 1 second is added. This has two advantages. One is that the material level is too high to seriously damage the filter element. This allows some customers to use the filter element for two and a half years. Second, you can clean the material each time. Close the feed valve to eliminate the material stop valve. The material stop valve will seriously damage the seal ring which is frequently operated, and the seal ring will open and close 5 to 6 times per minute.

2.自动混凝土搅拌机上料口的进料量是否合适？

2. Is the feeding rate of the feeding port of the automatic concrete mixer suitable?

我们的许多项目都使用手动物料枪来吸取物料。将物料枪直接插入物料桶或吨袋中，以便于操作。物料枪的物料吸入口被固体物料压缩，强大的负压将整个物料拉开。冒口极其有害，很容易堵塞管道。

Many of our projects use manual material guns to suck materials. Insert the material gun directly into the material barrel or ton bag for easy operation. The material inlet of material gun is compressed by solid material, and the whole material is pulled apart by strong negative pressure. Risers are extremely harmful and can easily clog pipes.

正确的方法是使物料在吸入口与空气形成特定的空气与物料的混合比，并在气流的推动下均匀地流入给料机。此时，有必要设计一种具有补气功能的材料枪。如果物料积压太长，可能会非常困难。这时，有必要在枪上安装振荡器，以破坏结块的材料。

The correct way is to make the material form a specific mixing ratio of air and material with air at the suction port, and flow into the feeder evenly under the push of air flow. At this time, it is necessary to design a kind of material gun with air supply function. If the material backlog is too long, it can be very difficult. At this time, it is necessary to install an oscillator on the gun to destroy the caked material.

在自动混凝土搅拌机的实际操作中，不可避免地会出现某些障碍。特别是，物料堵塞很严重，因此，我想让您了解如何使用上述自动进料混合机防止物料堵塞，然后执行正确合理的操作。

In the actual operation of automatic concrete mixer, there will inevitably be some obstacles. In particular, material blockage is very serious. Therefore, I want you to know how to use the automatic feed mixer mentioned above to prevent material blockage, and then carry out correct and reasonable operation.
