1. The feeding and mixing machine should not be repaired and lubricated during operation.
2. Regularly add grease to each grease fitting, lubricate the shaft end seal every 4 hours, and drain water once a week.
3. After using the feeding and mixing machine, add necessary lubricating oil (drum shaft, drum, wire rope and other effective parts) at each lubricating point as required.
4. The gears and bearings of the reducer of the feeding and mixing machine splash the oil into the inner wall of the oil tank and flow into the bearing for lubrication. The oil level of the gearbox should be maintained between the two lines of the oil gauge. If the oil level is too high or too low, the temperature of each part will rise or the lubrication will be poor, which will increase the power loss and lead to the poor operation of the machine.
5. The lubricating oil selected by the automatic feeding mixer should have certain viscosity and viscosity temperature characteristics, low freezing point, good oxidation stability, no mechanical impurities and moisture, no corrosion and wear-resistant materials. The quality index should meet the national standard.
The feeding and mixing machine is used for lubrication, reducing wear and improving the service life of components. However, in the process of adding lubricating oil, we need to pay attention to some matters. The new machine should be replaced once in the first 150 hours and 300 hours to remove dirt that was not completely cleaned during the test. When working, please check the oil level and add it in time.
Configuration and operation of feeding and mixing machine
The main related structures of the feeding and mixing machine are walking chassis, engine, hydraulic torque converter, double drive shaft, feeding device, feed hopper, discharge hopper, extended discharge hopper, frame, mixing drum and mixing are all slower. Machinery, hydraulic system, electronic control system, automatic water supply system, etc. Let's have a closer look.
1. The water inlet system can automatically feed water according to the weighing setting.
2. The rotation of the mixing drum is driven by a hydraulic motor through a special planetary gear. The output shaft of the planetary gear can swing at a constant angle to meet the beat of the mixing drum under bad road conditions.
3. The double helix blade is set on the inner wall of the mixing drum of the feeding and mixing machine, and the concrete is rotated forward and mixed, and the concrete is discharged from the outlet under the downward pressure of the spiral blade.
4. Supply dry materials, automatically supply the bucket arm, boom oil cylinder and metering hopper according to the design proportion.
5. Hydraulic system uses constant power variable displacement piston pump to reduce engine power loss.
6. The driving system is driven from the torque converter and the front and rear drive shafts to the front and rear axles. The use of the torque converter reduces the impact on the engine and extends the life of the engine.
