The main related structures of concrete mixer are walking chassis, engine, hydraulic torque converter, front and rear double drive axle, feeding device, feeding hopper, discharge hopper, extended discharge hopper, frame, mixing barrel, special deceleration for mixing. Machine, hydraulic system, electronic control system, automatic water supply system, etc. Let's take a closer look.

1.进水系统可根据计量设置实现自动进水。

1. The water inlet system can automatically feed water according to the metering settings.

2.搅拌筒的旋转由液压马达通过特殊的行星减速器驱动。行星减速器的输出轴可以以一定的角度摆动，以在恶劣的路况下满足搅拌筒的节拍。

2. The rotation of mixing drum is driven by hydraulic motor through special planetary reducer. The output shaft of planetary reducer can swing at a certain angle to meet the beat of mixing drum under bad road conditions.

3，双螺旋叶片安装在混凝土搅拌机搅拌筒内壁上，正向旋转进料和混凝土搅拌;在反向旋转中，混凝土在螺旋叶片的推动下从排出口排出。

3. The double spiral blade is installed on the inner wall of the mixing cylinder of the concrete mixer, and the concrete is fed and mixed in the positive direction; in the reverse direction, the concrete is discharged from the discharge outlet under the push of the spiral blade.

4.送入干燥物料，铲斗臂，动臂油缸和定量料斗按设计比例自动送料。

4. Feed dry materials, and the bucket arm, boom cylinder and quantitative hopper feed materials automatically according to the designed proportion.

5.液压系统使用恒功率可变排量活塞泵来减少发动机的动力损失。

5. The hydraulic system uses constant power variable displacement piston pump to reduce the power loss of the engine.

6.行走系统由发动机通过变矩器和前后驱动轴驱动到前后轴。变矩器的使用减少了对发动机的影响并延长了发动机的寿命。

6. The travel system is driven to the front and rear axles by the engine through the torque converter and the front and rear drive shafts. The use of the torque converter reduces the impact on the engine and extends the life of the engine.

上述小型系列中描述的知识内容是关于混凝土搅拌机的配置和操作知识。我相信大家都知道这点。在操作设备的过程中，非常有必要正确理解有关搅拌车的一些知识。

The knowledge content described in the above small series is about the configuration and operation of concrete mixer. I'm sure you all know that. In the process of operating the equipment, it is very necessary to correctly understand some knowledge about the mixer.
