The mechanical equipment of automatic feeding mixer will inevitably have some faults in long-term use. At this time, we need to clean up the mechanical soil residue. Then, let's learn more about how to clean the soil properly.

1.准备应急驱动软管，关闭小型混凝土搅拌车，然后卸下液压马达上的高压油管接头。

1. Prepare the emergency drive hose, close the small concrete mixer truck, and then remove the high-pressure oil pipe connector on the hydraulic motor.

2.关闭救援车辆，拆下其液压马达的高压油管，然后使用应急驱动软管将其连接到故障车辆上的相应接头。

2. Close the rescue vehicle, remove the high-pressure oil pipe of its hydraulic motor, and then connect it to the corresponding connector on the faulty vehicle with the emergency drive hose.

3.起动救援车，将其控制手柄移卸货位置，故障车辆中的混凝土将被卸出。

3. Start the rescue vehicle, move its control handle to the unloading position, and the concrete in the fault vehicle will be discharged.

4.应急驱动器完成后，卸下驱动器软管，将两辆车恢复到原始状态。

4. After the completion of the emergency drive, remove the drive hose and restore the two vehicles to the original state.

5.在支撑辊和滚道之间放一个木楔，以控制搅拌筒的旋转。请务必注意性；关闭发动机，然后松开液压马达的高压油管。搅拌筒可以自由旋转。

5. Put a wedge between the backup roll and the raceway to control the rotation of the mixing drum. Be sure to pay attention to safety; turn off the engine and then loosen the high pressure oil pipe of the hydraulic motor. The mixing drum can rotate freely.

6.控制搅拌桶的旋转，将维护孔转到底部，然后打开维护孔以清理桶中的混凝土。这时，必须注意性。排出混凝土后，将小型混凝土搅拌机恢复到原始状态。

6. Control the rotation of the mixing bucket, turn the maintenance hole to the bottom, and then open the maintenance hole to clean the concrete in the bucket. At this time, we must pay attention to safety. After the concrete is discharged, the small concrete mixer is restored to its original state.

在正常情况下，对混凝土搅拌车使用中出现的土壤渣进行合理的清洁可以确保所使用设备的良好运行性能。同时，在实际施工操作中，我们还需要更加注意设备的操作，也可以避免一些不必要的故障。

Under normal circumstances, the reasonable cleaning of soil slag in the use of concrete mixer can ensure the good operation performance of the equipment. At the same time, in the actual construction operation, we also need to pay more attention to the operation of the equipment, which can also avoid some unnecessary faults.
