Concrete mixing truck systems
Concrete mixing truck systems also called cement mixer truck, concrete transport trucks, mainly used for concrete batching plant which produce cement materials and should be transported, the common trucks such as Dongfeng trucks.
Concrete mixing truck systems include
Concrete mixer truck chassis using the engine power take off mode,Take the role of the force is applied by means full power drive power from the engine removed, the hydraulic system driven mixing tube, the mixing tube forward rotation of the feed and transport, in order to facilitate the feed and concrete stirring, when the reverse feed rotation, after the end of the work and cut engine power coupling.
The main function of the hydraulic system is to PTO power, into hydraulic energy (displacement and pressure), and then the motor output of mechanical energy (speed and torque), to provide power to turn the mixing tube.
After the output of the hydraulic motor speed reducer, passed to the mixing tube.
The control mechanism
Control the mixing drum rotation direction, so that the feed and transport the forward rotation, reverse rotation when the material.
Control the speed of the mixing tube.
Stirring device consists of mixing tube and the auxiliary support components. Mixing tube is loaded container concrete spiral rotation direction of movement of the concrete along the blade, 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 inversion, concrete discharged outward along the blade. Blade stirring device is the core component of damage or serious wear and tear can lead to uneven mixing concrete. In addition, if the angle of the blade design is unreasonable, but also to make concrete appear segregation.
Mixing system is used similarly to concrete mixers.
The main effect of the cleaning system is to clean the mixing tube, sometimes used for transit dry material mixing drum. Cleaning systems also hydraulic system cooling effect.
The cooling system
Cooling system uses a high-temperature cycle oil hydraulic pump, hydraulic motor during operation of the heat generated by the heat sink and fan dissipated, the hydraulic system to avoid the damage caused by high temperatures and malfunction.
Different types of concrete mixing trucks can be designed with different accessories, but the working principle should be similar or common.
