The 4 cubic-meter self-loading mixer truck is a kind of concrete mixer truck that is suitable for small-scale engineering construction and is equipped with automatic feeding, mixing, transportation and automatic unloading. High-power diesel engine and torque converter are used to ensure the power needed for walking and agitating at the same time. The main structure of the 4-cube self loading mixer consists of: walking chassis, engine, hydraulic torque converter, front and rear double drive bridges, feeding device, feed hopper, unloading hopper, extended hopper, rack, mixing drum, mixing Planetary reducer, hydraulic system, electronic control system, automatic water system and other components.
The 4 cubic-metre self-loading mixer is mainly composed of a base frame, a mixing drum, a transmission system (drive device), a hydraulic drive system, a water adding system, a loading and unloading system, a unloading chute, an operating platform, an operating system, and protection. Equipment composition. The working principle of the mixer drum: The type of the mixer drum used in this model is a common application structure. The mixer drum adopts a pear-shaped structure. The washing water and the mixing water added during the transportation process are added by the mixing drum head. The feed inlet is filled into the cylinder. Transmission system description: The mixing drum is driven by the engine as the power source. It is powered by the power takeoff device at the rear end of the engine. It is transmitted to the variable displacement hydraulic pump through the transmission shaft, and is driven by the reducer. The mixer drum rotates. Operation principle of the operating system: It is the control part of the whole mixer truck. The control panel is provided with an “I-shaped” groove, which is the active space of the joystick; and a limited position hole is opened on the groove of the rear half to fix the position of the joystick. . The control system controls the forward, reverse, and rotation speeds of the mixer through the two left and right joysticks on the rear of the vehicle to complete the infeed and discharge operations and the stirring action.
