Most people may not know much about the automatic feeding mixer. The automatic feeding mixer is mainly composed of the walking chassis, engine, hydraulic torque converter, front and rear double drive axles, feeding device, feed hopper, discharge hopper, extended discharge hopper, frame, mixing cylinder, special mixer reducer, hydraulic system, electric control system, automatic water feeding system, etc. Here, I will introduce some features of the automatic feeding mixer in detail. The specific features are as follows:
1. The rotation of the mixing drum of the self loading mixer is driven by the motor through a special planetary reducer. The output shaft of the planetary reducer can swing at a certain angle to meet the beating of the mixing drum under bad road conditions.
2. The hydraulic system adopts constant power variable piston pump to reduce the power loss of the engine.
3. The traveling system is from the engine to the front and rear axles through the hydraulic torque converter, front and rear transmission shafts. The invention adopts a front and rear double axle drive form. The hydraulic torque converter is used to reduce the impact on the engine and prolong the service life of the engine.
4. The dry material is automatically fed by shovel arm, boom cylinder and fixed hopper according to the designed proportion.
5. The water inlet system can automatically feed water according to the metering settings.
6. Double spiral blades are arranged on the inner wall of the mixing drum of the loading mixer truck, and the positive rotation is for feeding and concrete mixing; Reverse rotation, the concrete is discharged from the outlet under the push of the spiral blade.
