In the concrete mixer, the conveyor system is an important part. If there is a phenomenon that the conveyor belt transmits the aggregate unevenly, it is said that the aggregate accumulates on the conveyor belt, causing the conveyor belt to loosen or the polymer to be transported to the conveyor belt. Vacancies lead to lots of pebbles.

分析的原因是，可以随时调整从配料站排放到皮带上的各种骨料的顺序和时间间隔。通常，卸载顺序要求所卸载的聚合物是沙子。卸载间隔要求落在皮带上的前骨料的尾部与落在皮带上的后骨料的头重合。

The reason for the analysis is that the sequence and time interval of various aggregates discharged from the batching station to the belt can be adjusted at any time. Generally, the unloading sequence requires that the polymer to be unloaded is sand. The unloading interval requires that the tail of the front aggregate falling on the belt coincides with the head of the back aggregate falling on the belt.

如果时间间隔太短，则前一个和下一个聚合具有重叠的堆。过多的绒毛材料可能会导致散装材料。如果时间间隔太大，则两个聚合之间将存在间隙。前一种类型，如果材料是鹅卵石，它将在皮带上滚动并展开。

If the time interval is too short, the previous and next aggregations have overlapping heaps. Too much fluff material can cause bulk material. If the time interval is too large, there will be a gap between the two aggregations. In the former type, if the material is pebbles, it will roll on the belt and unfold.

方案：调整集料的卸载顺序，以确保卸载沙子。根据皮带上骨料的分布，调整各种骨料的卸载时间间隔，以确保物料在皮带上的连续，均匀分布。时间间隔通常需要进行多次调整。

Solution: adjust the unloading sequence of aggregate to ensure unloading of sand. According to the distribution of aggregate on the belt, the unloading time interval of various aggregates is adjusted to ensure the continuous and uniform distribution of materials on the belt. The time interval usually needs to be adjusted several times.

混凝土搅拌机的故障排除方法9.空气源三缸压力释放阀的压力无法调节。旋转减压阀调节手轮，但压力无法调节。原因分析：减压和反进口的方向相反。嵌入异物或阀体的阀体的滑动部分的异物卡在珠海中。压力调节弹簧，复位弹簧，膜片，阀芯上的橡胶垫等会损坏。

The trouble shooting method of concrete mixer 9. The pressure of three cylinder pressure relief valve of air source can not be adjusted. Rotate the pressure reducing valve to adjust the hand wheel, but the pressure cannot be adjusted. Cause analysis: the direction of decompression and anti import is opposite. The foreign matter embedded in the valve body or the sliding part of the valve body is stuck in Zhuhai. The pressure regulating spring, return spring, diaphragm and rubber pad on valve core will be damaged.

在混凝土搅拌机运行期间，操作员应注意主电动机的电流，并禁止过载运行。为了在打开或关闭混合储罐时准确地装载和卸载物料，可以使用麦克风和声音放大器打电话，以便驾驶员可以调整卡车在混合储罐下的位置以完成工作。麦克风也可以在启动前用作警告，或者在发生事故或生产过程中发生事故时提醒户外作业人员。

During the operation of the concrete mixer, the operator should pay attention to the current of the main motor and prohibit overload operation. In order to accurately load and unload materials when opening or closing the mixing tank, the microphone and sound amplifier can be used to make phone calls so that the driver can adjust the position of the truck under the mixing tank to complete the work. The microphone can also be used as a warning before start-up, or as a reminder to outdoor workers in the event of an accident or an accident in the production process.
