Cement mixer mainly dedicated accessories, including power take off, before mixing tube frame, gearbox, hydraulic systems, the mixing tube, the control mechanism, cleaning systems. How it works: by the power take off power to remove the vehicle chassis and drive the hydraulic pump hydraulic system, the mechanical energy into hydraulic energy transmitted to the hydraulic motor, motor-driven gear and then, by the reducer drive mixing system of concrete stirring . Stirring device: mixing device consists of mixing tube and ancillary support components. Mixing tube is loaded container concrete spiral rotation direction of movement along the blade of concrete, constantly upgrading and turning process by mixing and stirring. In the feeding and transportation process, the mixing tube is transferred, the concrete along the blade inward movement, when the material, the mixing tube reversal, concrete discharged outward along the blade. Blade stirring device is the main component, can lead to damaged or badly worn concrete uneven mixing. In addition, if the angle of the blade design is unreasonable, but also to the concrete segregation. Cleaning system: The main role of the cleaning system is to clean the mixing tube, sometimes for transit mix dry feed tube. Cleaning system further cooling effect of the hydraulic system. Closure means: fully enclosed device using rotary sealing technology, sealing the mixer's expected out to solve the traditional mixer water evaporation, layered mortar, concrete material spilled, traffic safety and other issues.
