Concrete mixer - the principle of structural concrete mixer. Concrete mixer truck chassis and concrete mixing by car transport special equipment components. China's production of concrete mixer truck chassis to use more vehicle manufacturers to provide two types of common chassis. Its private institutions including the PTO, before mixing tube frame, gearbox, hydraulic systems, the mixing tube, the control mechanism, cleaning systems. Works by taking the power plant will power the car chassis removed and driven variable displacement pump hydraulic system, the mechanical energy into hydraulic energy to pass quantitative motor, motor-driven gear again, driven by the reducer stirring device, to make concrete stir. 1. Schematic mixer knot purchase PTO device domestic concrete mixer truck using the main vehicle engine power take off mode. Take the role of a power plant operated by PTO switch will remove the engine power, the hydraulic system driven mixing tube, mixing tube forward rotation of the feed and transport to facilitate feeding and concrete stirring anti-discharging when rotating, after the end of cutting the work with the engine power is coupled. 2. The hydraulic system via engine power PTO removed, into hydraulic energy (displacement and pressure), and then the output of the motor into mechanical energy (speed and torque), to provide power for rotating the mixing tube. We are factory direct, ex-factory sales directly, eliminating the intermediate links, so that the lowest price! 3. reducer after the hydraulic system of the motor output speed reducer, passed to the mixing tube. The control mechanism (1) controlling the rotational direction of the mixing tube, so that in the feed and transport the forward rotation, reverse rotation when the material. (2) control the speed of the mixing tube. 5. The mixing device consists of mixing tube mixing device and auxiliary 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. Sales commitment: one year warranty chassis part, if any quality problems at the local service station for a free warranty. Body part year warranty, wearing parts warranty for one year. As part of the tank during the warranty period, the manufacturer warranty for free for users. Manufacturers will be between 12-24 hours of free service to users rushed to the scene. Tank as part of the warranty period, the manufacturer warranty for users, parts only charge fees.
