The power of the mixer of the fully automatic mixing truck is transmitted to the hydraulic pump through the transmission shaft by the power extractor of the secondary chassis. The hydraulic energy generated by the hydraulic pump is transmitted to the hydraulic motor through the oil pipe. The hydraulic motor converts hydraulic energy into kinetic energy and transmits it to the mixing tank through a reducer. After using for a period of time, too many or too few mixing drums will cause mixing to fail, generally in three situations:
1. The concrete is stuck during transportation;
2. Hydraulic system or engine failure;
The motor is out of order.
The concrete is stuck during transportation; Clean it up and there's no problem;
Troubleshooting of hydraulic system or engine faults:
(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 to make the manhole of the mixing drum incline downward, and discharge concrete from the manhole of the mixing drum;
(2) The high-pressure hose of the troublesome truck is connected from the relief motor to the oil pump rescue vehicle at the other end using a high-pressure hose, which will then be used to rescue the vehicle after the emergency water return pipe has an oil port of the troublesome truck, and the other end of the oil return pipe uses a pump suction port. The rescue vehicle is used to control the rotating cylinder of the troublesome truck, with specific emissions.
The handling of motor faults is relatively simple. The motor can be removed from the rescue vehicle and installed on the faulty vehicle, and then all oil pipes can be connected. When starting the rescue vehicle, concrete cylinders can be mixed out.
As a transportation vehicle, fully automatic mixer trucks should comply with the maintenance regulations of the Ministry of Communications, and implement a maintenance system of "regular inspection, mandatory maintenance, and maintenance as appropriate.". Under this premise, combined with the actual situation of fully automatic mixer trucks, maintenance and repair work should be done well. In terms of daily maintenance, vehicles should be maintained in accordance with the daily maintenance of automobile engines, chassis, and other components, and maintenance work must also be done well.
