The driving force of the full-automatic self feeding mixer is output by the full power take-off of the class II chassis. According to the transmission shaft, the driving force is transmitted to the hydraulic pump. The hydraulic energy formed by the hydraulic pump is transmitted to the hydraulic motor according to the oil pipe. The hydraulic motor converts the hydraulic energy into power and transmits it to the mixing tank according to the speed reduction and torque increase of the reducer.

在應用到相應時間以后，過多太少的會出現拌筒不可以轉動，通常有3種情況：

After the application to the corresponding time, too much or too little will cause the mixing drum not to be able to rotate. There are usually three cases:

1、運輸歷程中有混泥土卡住了；

1. The concrete got stuck during transportation;

2、液壓系統或發動機出現系統故障；

2. Hydraulic system or engine system failure;

3、馬達出現系統故障。

3. The motor has a system fault.

應對方式：

Coping style:

1、運輸歷程中有混泥土卡住了；清理干凈就沒問題了；

1. The concrete got stuck during transportation; It's OK to clean it up;

2、液壓系統或發動機故障的處置：

2. Disposal of hydraulic system or engine fault:

（1）開啟攪拌筒檢修孔蓋，旋松馬達上高壓軟管的管接頭，旋轉拌筒使拌筒檢修孔斜朝下，將砼從攪拌筒檢修孔排出來；

(1) Open the manhole cover of the mixing drum, loosen the pipe joint of the high-pressure hose on the motor, rotate the mixing drum so that the manhole of the mixing drum is inclined downward, and discharge the concrete from the manhole of the mixing drum;

（2）將故障車的高壓膠管從馬達上卸下來，把援救用的高壓膠管連上，另一頭接進救援車的油泵上，并將應急用的回油管一邊接進故障車的馬達泄油口，回油管另一頭接進救援車的油泵回油口，運用救援車來調節故障車拌筒的旋轉，將砼排出來。

(2) Unload the high-pressure hose of the fault vehicle from the motor, connect the high-pressure hose for rescue, connect the other end to the oil pump of the rescue vehicle, connect one side of the emergency oil return pipe to the motor oil drain port of the fault vehicle, and connect the other end of the oil return pipe to the oil return port of the oil pump of the rescue vehicle. Use the rescue vehicle to adjust the rotation of the mixing cylinder of the fault vehicle and discharge the concrete.

3、馬達出現系統故障，處置則較簡易，可把救援車的馬達卸下來裝在系統故障車上，再將每個油管接上，運行救援車就可以將拌筒內的砼排出來。

3. If there is a system fault in the motor, the disposal is relatively simple. The motor of the rescue vehicle can be unloaded and installed on the system fault vehicle, and then each oil pipe can be connected, and the concrete in the mixing drum can be discharged by running the rescue vehicle.
