In the long-term use of concrete machinery such as automatic feeding mixer, some failures will inevitably occur. At this time, we need to carry out a certain cleaning work on the mechanical soil slag. So let's take a closer look at how to clean up the soil properly.
1. Prepare the emergency drive hose, close the mixer, and then remove the high pressure oil pipe connector from the hydraulic motor.
2. The rescue vehicle was closed, the high-pressure oil pipe of the hydraulic motor was removed, and the corresponding connector on the fault vehicle was connected with the emergency drive hose.
3. Start the rescue truck and turn its handle to the unloading position. Discharge of concrete from the faulty vehicle.
4. After the emergency drive is completed, remove the drive hose and restore the original condition of both vehicles.
5. A wooden wedge is placed between the roller and the raceway to control the rotation of the mixer. Pay attention to safety. Shut down the engine and remove the high pressure oil pipe from the hydraulic motor. The mixer can rotate freely.
6. Control the rotation of the mixing drum, turn the maintenance hole to the lower part, and then open the maintenance hole to clean the concrete in the cylinder. At this time, be sure to be safe. After the concrete is discharged, the original full-automatic feeding mixer is restored.
Automatic feeding mixer is mainly suitable for urban construction and construction, which is specially used to transport the concrete required by buildings and always keeps mixing state during transportation, so as to ensure that concrete will not set. How to prolong its service life?
1. For newly purchased vehicles, the initial use of 50h control, it is necessary to check the tightening of bolts everywhere. It includes the connecting bolts between the tank split and the reducer, the connecting bolts between the reducer base and the front desk, the connecting bolts between the tugboat base and the frame, and the connecting bolts between the auxiliary beam and the main beam. In the future, we should make sure to check on time every month.
2. The accuracy of hydraulic system components is high. Especially the mixer hydraulic pump, maintenance is simple, but the appeal is very high. The hydraulic oil should be replaced on time. The initial working time is 500h, and the next 2000h or at least once a year. The filter element should be replaced at the same time. When refueling or changing oil, it is suggested that the machine should be in the termination condition, otherwise the hydraulic system will be damaged.
3. Check whether the lubricating oil on the contact surface of tugboat and raceway is dry and astringent before driving every day. It should be compensated in time and adhere to the outstanding lubrication function. Check the oil level of cooler and reducer to ensure that the oil level indication is within the visual range before the vehicle proposal; check the sealing condition of the hydraulic oil circuit, adhere to the cleaning and sealing of the hydraulic system, and prevent dust particles and water from polluting the hydraulic oil of the system, causing the system to fail to work normally or be damaged. Clean up the dirt on the tugboat and raceway at least once a month; write grease to the tug through the nozzle on the tug. Ensure that the rotating shaft is lubricated at least once a month.
4. It is forbidden to weld and change the water tank at will to prevent heavy objects from hitting; the water level display pipe and filter screen should be replaced in time to prevent blockage and affect the partition; various valve bodies should be often checked for blockage or abnormal operation, and lubrication should be carried out in time; it should be used in the environment with icing.
