Special mechanisms mainly include: power takeoff, front and rear supports of mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system, etc.
取力装配：国产混凝土搅拌运输车接纳主车策念头取力体例。取力装配的感化是经由进程支配取力开关将策念头能源掏出，经液压体系驱动搅拌筒，搅抖筒在进料和运输进程中正向扭转，以利于进料和对混凝土停止搅拌，在出料时反向扭转，在任务闭幕后堵截与策念头的能源连接。
Power take-off device: domestic concrete mixer truck adopts the power take-off mode of main vehicle engine. The function of the power take-off device is to take out the power of the engine by operating the power take-off switch, drive the mixing drum through the hydraulic system, and the mixing drum rotates forward during feeding and transportation, so as to facilitate feeding and mixing of concrete, rotate reversely during discharging, and cut off the power connection with the engine after the end of work.
液压体系：将经取力器掏出的策念头能源(此刻普通都是后置全功效取力器)，转化为液压能(排量和压力)，再经马达输入为机器能(转速和扭矩)，为搅拌筒动弹供给能源。
Hydraulic system: convert the engine power taken out by the power take-off (now generally rear full-function power take-off) into hydraulic energy (displacement and pressure), and then output into mechanical energy (speed and torque) through the motor to provide power for the rotation of the mixing drum.
加速机：将液压体系中马达输入的转速加速后，传给搅拌筒。
Reducer: after decelerating the speed output by the motor in the hydraulic system, it is transmitted to the mixing drum.
支配机构：
Operating mechanism:
a．节制搅拌筒扭转标的目的，使之在进料和运输进程中正向扭转，出料时反向扭转。
a. Control the rotation direction of the mixing drum to make it rotate forward during feeding and transportation and reverse during discharging.
b．节制搅拌筒的转速。
b. Control the rotating speed of the mixing drum.
搅拌装配：它首要由搅拌筒及其帮助撑持部件构成。搅拌筒是混凝土的装载容器，它是由优良耐磨薄钢板制成，为了可以或许主动装、卸混凝土，其内壁焊有特别外形的螺旋叶片。动弹时混凝土沿叶片的螺旋标的目的活动，在不时的晋升和翻动进程中遭到夹杂和搅拌。在进料及运输进程中，搅拌筒正转，混凝土沿叶片向里活动，出料时，搅拌筒反转，混凝土沿着叶片向外卸出。
Mixing device: it is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a concrete loading container, which is made of high-quality wear-resistant steel plate. In order to automatically load and unload concrete, its inner wall is welded with spiral blades of special shape. When rotating, the concrete moves along the spiral direction of the blade and is mixed and stirred in the process of continuous lifting and turning. During feeding and transportation, the mixing drum rotates forward, and the concrete moves inward along the blade. When discharging, the mixing drum reverses, and the concrete is discharged outward along the blade.
搅拌筒的动弹则是靠液压驱动装配来保障。装载量为3～6立方。的混凝土搅拌运输车普通接纳由汽车策念头经由进程能源输入轴动员液压泵，再由高压油鞭策液压马达驱动搅拌筒，装载量为9～12立方的则由车载帮助柴油机动员液压泵驱动液压马达。叶片是搅拌装配中的首要部件，破坏或严峻磨损会致使混凝土搅拌不平均。别的，叶片的角度若是设想分歧理，还会使混凝土呈现离析。
The rotation of the mixing drum is guaranteed by the hydraulic driving device. The loading capacity is 3 ~ 6 cubic meters. Generally, the truck engine drives the hydraulic pump through the power output shaft, and then the high-pressure oil drives the hydraulic motor to drive the mixing drum. For the truck with a loading capacity of 9 ~ 12 cubic meters, the on-board auxiliary diesel engine drives the hydraulic pump to drive the hydraulic motor. Blade is the main component of mixing device. Damage or serious wear will lead to uneven mixing of concrete. In addition, if the design of blade angle is unreasonable, the concrete will be separated.
洗濯体系：洗濯体系的首要感化是洗濯搅拌筒，偶然也用于运输途中停止干料搅拌。洗濯体系还对液压体系起冷却感化。
Cleaning system: the main function of the cleaning system is to clean the mixing drum, and sometimes it is also used for dry material mixing during transportation. The cleaning system also cools the hydraulic system.
