The power take-off drives the hydraulic motor of the hydraulic pump to rotate through the small transmission shaft, and drives the mixing drum to rotate through the reducer. During the transportation of concrete, it is necessary to keep the mixing tank rotating at a low speed of 1-3 revolutions per minute to ensure the uniformity of concrete and prevent concrete segregation, which is called stirring (commonly known as mixing).

搅拌车在装混凝土的时候搅拌罐转速较快，速度为每分钟6-10转，混凝土通过装料系统从筒口导管进入搅拌筒，并在螺旋叶片引导下，流向搅拌筒的中下部。注意：装料时与运输过程中罐体的转动方向应保持一致，否则在运输过程中会将混凝土卸出。

When the mixer truck is loading concrete, the speed of the mixing tank is fast, with a speed of 6-10 revolutions per minute. The concrete enters the mixing drum from the barrel opening conduit through the loading system and flows to the middle and lower part of the mixing drum under the guidance of spiral blades. Note: the rotation direction of the tank body during loading shall be consistent with that during transportation, otherwise the concrete will be unloaded during transportation.

搅拌车在卸料时，发动机将动力通过取力器，液压泵，减速机等传输到搅拌罐，带动罐体转动，速度为3-14转/分；混凝土在 叶片螺旋运动的顶推作用下向筒口方向移动，经过搅拌车的卸料斗卸出。此时罐体的转动方向与进料时的方向相反。

When the mixer truck is unloading, the engine transmits the power to the mixing tank through the power take-off, hydraulic pump and reducer to drive the tank to rotate at a speed of 3-14 rpm; The concrete moves towards the cylinder mouth under the pushing action of the blade spiral movement and is discharged through the discharge hopper of the mixer truck. At this time, the rotation direction of the can body is opposite to that during feeding.

通过制动系统的储气筒给水罐加压，水流经过加压清洗搅拌罐系统，装料口，卸料系统等。

Pressurize the water tank through the air reservoir of the braking system, and the water flows through the pressurized cleaning mixing tank system, loading port, unloading system, etc.

这些知识相对搅拌车的使用者来说可能先对比较的简单，但对于没有接触过，想进入搅拌车行业的初学者来说还是可以认真看看，学习的。如果文中有什么错误，也希望大家及时讨论指正。

These knowledge may be relatively simple for the users of the mixer truck, but for the beginners who have not contacted and want to enter the mixer truck industry, they can still take a serious look and learn. If there are any mistakes in the text, I hope you can discuss and correct them in time.
