The structure and working principle of the mixer â— Ten components of a concrete mixer truck Ten main components of a concrete mixer The concrete mixer truck is mainly composed of a chassis and a top part, which can be simply divided into: a chassis system, a hydraulic transmission system, a mixing tank, a discharging system, a cleaning system, a sub-frame, an operating system, a supporting wheel system, and a feeding system. , Circuit system consists of ten parts. 1. Undercarriage: The main component of a mixer truck. The transport function of the concrete mixer truck is realized by the chassis. 2. Hydraulic transmission system : The engine power taken out by the power takeoff is converted into hydraulic energy (displacement and pressure), and then the motor output is mechanical energy (speed and torque), which provides power for the rotation of the mixer drum. 3. Stirring tank : The mixing drum is a key component of the entire mixing truck and is a container for storing concrete. It plays a decisive role in preventing the concrete from solidifying and segregating. The inside of the tank has blades, which mainly play the role of stirring and guiding. 4, the discharge system : mainly by the main unloading tank, auxiliary unloading tank, locking rods and other components, the auxiliary unloading tank to extend the length of the main unloading tank role. 5. Cleaning system : The cleaning system is mainly composed of pressure water tank, water gun, water pipe and valve. The use of air pressure water supply, the main role is to rinse the hopper after loading and unloading the material is completed and rinse the mixing tube, unloading tank to prevent concrete bonding. 6. Sub-frame: The sub-frame of the mixer is the main load-bearing part. The load during operation is almost always supported by it and then transferred to the chassis. The subframe also plays a role in alleviating the bumping and deceleration of the road surface. The entire sub-frame consists of a main beam, a front support frame and a background support frame. 7. Operating system : The operating system is composed of a controller, a linkage shaft, a flexible shaft and a linkage mechanism, which mainly controls the rotational speed and the rotation direction of the mixing drum. 8. Supporting wheel system : The part of the rear side of the mixing tank that is connected with the sub-frame is mainly used to support the drum body. 9, the feed system : mainly by the hopper and the composition of the bracket, the hopper due to the impact of greater wear and tear, the material requires good wear resistance, the stent mainly to reduce the impact of the role. 10, the circuit system : mainly refers to the entire circuit of the mixer, including the vehicle's taillights, side sign lights, gallery lights, cooling fan motors. â— The four working principle of the mixer Mixer stirring function principle: The power take-off device drives the engine's power through a small drive shaft to drive the hydraulic pump's hydraulic motor to rotate, and the speeding machine drives the stirring barrel to rotate. During the transportation of concrete, it is necessary to keep the stirring tank at a low speed of 1-3 rotations per minute to ensure the homogeneity of the concrete and prevent the segregation of the concrete, which is called agitation (commonly known as agitation). Mixer loading function principle: When the mixer truck is loaded with concrete, the speed of the stirring tank is 6-10 revolutions per minute. The concrete enters the mixer tube through the tube inlet pipe through the loading system, and flows to the middle and lower part of the mixer tube under the guidance of the spiral blade. Note: The direction of rotation of the tank during loading and during transportation should be the same, otherwise the concrete will be unloaded during transportation. Mixer unloading function principle: When the mixer truck is unloading, the engine transmits the power to the mixing tank through the power take-off device, hydraulic pump, speed reducer, etc., which drives the tank to rotate at a speed of 3-14 rpm; the concrete under the jacking action of the blade spiral movement Move toward the nozzle and discharge it through the hopper of the mixer. The direction of rotation of the tank at this time is opposite to the direction of feeding. Mixer cleaning function principle: The water tank of the braking system is pressurized to the water tank, and the water flows through the pressurized cleaning tank system, the charging port, and the unloading system.
