The power of the agitator is transmitted to the hydraulic pump through the transmission shaft by the power extractor of the secondary chassis. The hydraulic energy produced by the hydraulic pump is transmitted to the hydraulic motor through the oil pipe. The hydraulic motor converts the hydraulic energy into kinetic energy, which is transmitted to the mixing tank through the reducer.
After using for a period of time, too many and too few mixing buckets will not rotate, generally there are three situations:
1. The concrete is stuck during transportation;
2. Hydraulic system or engine failure;
3. The motor is out of order.
1. The concrete is stuck during transportation; there is no problem if it is cleaned up;
2. Troubleshooting of hydraulic system or engine:
(1) Open the manhole cover of the mixing barrel, loosen the pipe joint of the high-pressure hose on the motor, rotate the mixing barrel to make the manhole of the mixing barrel incline downward, and discharge the concrete from the manhole of the mixing barrel;
(2) The high-pressure hose of the troublesome truck is connected to the oil pump rescue vehicle at the other end by the high-pressure hose from the relief motor. Finally, the rescue vehicle is used to rescue the truck after the emergency return pipe has the troublesome truck oil port and the other end of the return pipe uses the pump pumping port. The rescue vehicle is used to control the rotating cylinder of the troublesome truck, and the specific discharge.
3. The treatment of motor failure is relatively simple. The motor can be removed from the rescue vehicle and installed on the failure vehicle, and then the oil pipes can be connected. When the rescue vehicle is started, the concrete cylinder can be mixed out.
As a transport vehicle, the small concrete mixer shall comply with the maintenance regulations of the Ministry of communications, and implement the maintenance system of "regular inspection, compulsory maintenance and maintenance as appropriate". Under this premise, combined with the actual situation of concrete mixer, do a good job in maintenance. In terms of daily maintenance, the concrete mixing transport vehicle shall be maintained in accordance with the daily maintenance of automobile engine, chassis and other components, and the following maintenance work must be done well.
