Self mixing concrete mixer can be divided into dry mixing truck and wet mixing truck according to different loading materials. We usually use wet mixing mode. The working principle of the mixer truck is as follows: the power take-off transmits the energy of the engine to the hydraulic pump through the transmission shaft, and the hydraulic energy generated by the hydraulic pump is transmitted to the hydraulic motor through the oil pipe. The hydraulic motor converts the hydraulic energy into kinetic energy, and then transmits it to the mixing tank through the reducer. Through the servo handle angle of the hydraulic pump, the positive and negative rotation speed of the mixing tank can be realized to realize loading and stirring Mixing, stirring, discharging, etc. Each part of the mixer has its own function, which is introduced below.

搅拌功能：自拌混凝土搅拌车，发动机动能由取力器取出，再传给小传动轴，带动液压泵马达转动，经过减速机带动搅拌罐转动。在车辆的行驶途中，需要保持搅拌罐每分钟1-3分钟的低速转动，以保证混凝土的均匀，同时还可防止混凝土离析。

Mixing function: for the self mixing concrete mixer, the kinetic energy of the engine is taken out by the power take-off, and then transmitted to the small transmission shaft to drive the hydraulic pump motor to rotate, and the reducer to drive the mixing tank to rotate. During the driving of the vehicle, it is necessary to keep the mixing tank rotate at a low speed of 1-3 minutes per minute to ensure the uniformity of concrete and prevent concrete segregation.

装料功能：自拌混凝土搅拌车在装料的时候转速是比较快的，大约每分钟为6-10转的样子，混凝土通过装料系统从进料口进入搅拌罐，并在螺旋叶片的搅动下，流向搅拌罐的中下部。

Loading function: the rotation speed of the self mixing concrete mixer truck is relatively fast when loading, about 6-10 revolutions per minute. The concrete enters the mixing tank from the feeding port through the loading system, and flows to the middle and lower part of the mixing tank under the stirring of spiral blades.

卸料功能：卸料也是有取力器从发动机取力，再通过液压泵，减速机等输送到搅拌罐，带动罐体转动，速度一般为3-14转/分钟；此时混凝土在螺旋叶片的作用下向卸料口移动，在经过卸料口卸出，此时罐体的转动方向与进料时的方向相反。

Unloading function: the power take-off device takes power from the engine, and then it is transported to the mixing tank through the hydraulic pump and reducer to drive the tank to rotate, with a speed of 3-14 rpm. At this time, the concrete moves to the discharge port under the action of spiral blades and is discharged through the discharge port. At this time, the rotation direction of the tank body is opposite to that of the feeding.

清洗功能：清洗功能主要是清洗搅拌罐和进出料口，它是通过制动系统的储气罐给水箱加压，水在压力的作用下就可以清洗搅拌罐、进出料口等等地方。

Cleaning function: the cleaning function is mainly to clean the mixing tank and the material inlet and outlet. It is pressurized by the water tank of the air storage tank of the brake system. Under the pressure, the water can clean the mixing tank, the material inlet and outlet, etc.

可以看出操作基本上都是人工智能化，简单快捷，而且又能保证混凝土的质量。现在大部分的建筑工地都在使用自拌混凝土搅拌车。

It can be seen that the operation is basically artificial intelligence, simple and fast, and can ensure the quality of concrete. Now most construction sites are using self mixing concrete mixer.
