1、 Power take-off device

自上料搅拌机采用发动机取力方式，取力装置的作用是通过操纵取力开关将发动机动力取出，经液压系统驱动搅拌筒，搅抖筒在进料和运输过程中正向旋转，以利于进料和对混凝土进行搅拌，在出料时反向旋转，在工作终结后切断与发动机的动力联接。

The self loading mixer adopts the engine power take-off mode. The function of the power take-off device is to take out the power of the engine by operating the power take-off switch, and drive the mixing drum through the hydraulic system. The mixing drum rotates in a positive direction during the process of feeding and transportation, so as to facilitate the feeding and mixing of concrete. The power take-off device rotates in a reverse direction when discharging, and cuts off the power connection with the engine after the end of the work.

二、液压系统

2、 Hydraulic system

将经取力器取出的发动机动力，转化为液压能(排量和压力)，再经马达输出为机械能(转速和扭矩)，为搅拌筒转动提供动力。

The engine power taken out by the power take-off is converted into hydraulic energy (displacement and pressure), and then output into mechanical energy (speed and torque) by the motor to provide power for the rotation of the mixing drum.

三、减速机

3、 Reducer

将液压系统中马达输出的转速减速后，传给搅拌筒。

The speed of the motor output in the hydraulic system is decelerated and transmitted to the mixing drum.
                      

四、操纵机构

4、 Operating mechanism

控制自上料搅拌机搅拌筒旋转方向，使之在进料和运输过程中正向旋转，出料时反向旋转。控制搅拌筒的转速。

Control the rotation direction of the mixing drum of the self feeding mixer to make it rotate forward in the process of feeding and transportation and reverse in the process of discharging. Control the rotation speed of the mixing drum.

五、搅拌装置

5、 Mixing device

自上料搅拌机主要由搅拌筒及其辅助支撑部件组成。搅拌筒是混凝土的装载容器，它是由优良耐磨薄钢板制成，为了能够自动装、卸混凝土，其内壁焊有特殊形状的螺旋叶片。

The self loading mixer is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a loading container for concrete. It is made of fine wear-resistant steel sheet. In order to load and unload concrete automatically, the inner wall of the mixing drum is welded with spiral blades of special shape.

转动时混凝土沿叶片的螺旋方向运动，在不断的提升和翻动过程中受到混合和搅拌。在进料及运输过程中，搅拌筒正转，混凝土沿叶片向里运动，出料时，搅拌筒反转，混凝土沿着叶片向外卸出。

When it rotates, the concrete moves along the spiral direction of the blade, and is mixed and stirred in the process of continuous lifting and turning. In the process of feeding and transportation, the mixing drum rotates forward and the concrete moves inward along the blades. When discharging, the mixing drum reverses and the concrete is discharged outward along the blades.

搅拌筒的转动则是靠液压驱动装置来保证。装载量为3～6立方的自上料搅拌机一般采用由汽车发动机通过动力输出轴带动液压泵，再由高压油推动液压马达驱动搅拌筒，装载量为9～12立方的则由车载辅助柴油机带动液压泵驱动液压马达。叶片是搅拌装置中的主要部件，损坏或严重磨损会导致混凝土搅拌不均匀。另外，叶片的角度如果设计不合理，还会使混凝土出现离析。

The rotation of the mixing drum is ensured by the hydraulic driving device. For the self loading mixer with a loading capacity of 3-6 cubic meters, the vehicle 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 mixer with a loading capacity of 9-12 cubic meters, the vehicle auxiliary diesel engine drives the hydraulic pump to drive the hydraulic motor. The blade is the main component of the mixing device, and damage or serious wear will lead to uneven mixing of concrete. In addition, if the blade angle is not reasonable, the concrete will appear segregation.
