The small mixer adopts the main vehicle 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 forward in the process of feeding and transportation to facilitate the feeding and mixing of concrete. It rotates reversely when discharging, and cuts off the power connection with the engine after the end of the work

小型搅拌机液压系统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 hydraulic system of the small mixer converts the engine power taken out by the power take-off into hydraulic energy (displacement and pressure), and then outputs mechanical energy (speed and torque) through the motor to provide power for the rotation of the mixing drum.

小型搅拌机减速机将液压系统中马达输出的转速减速后，传给搅拌筒。

The reducer of small mixer decelerates the speed of motor output in the hydraulic system and transmits it to the mixing drum.

小型搅拌机操纵机构：

Small mixer control mechanism:

（1）控制搅拌筒旋转方向，使之在进料和运输过程中正向旋转，出料时反向旋转。

(1) Control the rotation direction of the mixing drum to make it rotate forward in the process of feeding and transportation, and reverse rotation when discharging.

（2）控制搅拌筒的转速。

(2) Control the speed of mixing drum.

小型搅拌机搅拌装置：

Small mixer mixing device:

搅拌装置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，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。

The mixing device is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a container for loading concrete. When rotating, the concrete moves along the spiral direction of the blade, and is mixed and mixed 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 blade. When discharging, the mixing drum reverses and the concrete is discharged outward along the blade.

小型搅拌机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 blade of small mixer is the main part of mixing device. The damage or serious wear will lead to uneven mixing of concrete. In addition, if the angle of blade is not reasonable, it will cause concrete segregation.
