The movement process of automatic feeding mixer mainly includes the movement of engine, hydraulic components (oil system, hydraulic motor, reducer) and mixing drum. Firstly, the engine provides the power source, and then the power is transmitted to the hydraulic motor through rape, and then the reducer decelerates to increase the torque, and finally realizes the rotation of the drum. Because the control terminal is the rotation speed of the mixing drum, and the speed of the mixing drum is determined by the movement of the four parts of the device, the motion analysis process will mainly include the engine, hydraulic components and other parts.

自动上料搅拌车一般使用柴油机作为发动机，因我过内燃机技术相对国外较为落后，因此在自动上料搅拌车上一般使用国外进口柴油机，目前公司使用的柴油机大多由日本生产，机型包括、、等。现已系列柴油机进行介绍和分析。

The diesel engine is generally used as the engine of the automatic feeding mixer. As the internal combustion engine technology of our company is relatively backward compared with foreign countries, the imported diesel engine is generally used on the automatic feeding mixer. At present, most of the diesel engines used by the company are produced in Japan, including, and etc. The series of diesel engines have been introduced and analyzed.

系列柴油机是紅直列、活塞式、水冷、增压才有发动机。紅径，行程、虹心距、净重功率覆盖范围为。

Series diesel engine is red in-line, piston type, water-cooled, supercharged engine. Red path, stroke, rainbow center distance, net weight and power coverage are.

减速机：目前我公司主要采用的是意大利、德国、意大利的减速机，此减速机釆用行星传动齿轮箱，结构紧凑，传动效率高，运转可靠易于维护保养。

Reducer: at present, our company mainly adopts the reducer of Italy, Germany and Italy. The reducer adopts planetary gear box, with compact structure, high transmission efficiency, safe and reliable operation and easy maintenance.

搅拌耀速度控制：根据“发动机转速油菜排量马达排量减速机减速比耀体转速，其中马达排量、减速机减速比是常数，罐体转速如果恒定为常数，则只要发动机转速油粟排量为常数即可【。

Speed control of agitator: according to "engine speed, rape displacement, motor displacement, reducer deceleration ratio, the motor displacement and reducer reduction ratio are constant, if the tank speed is constant, then as long as the engine speed and oil displacement are constant [.

电子恒速传动方案是把液压粟的控制形式改为电比例控制，液压录输出流量与输入电流成正比，通过调节比例阀的输入电流，改变液压粟斜盘角度，从而达到调速目的。

The scheme of electronic constant speed transmission is to change the control form of hydraulic pump to electric proportional control. The output flow of hydraulic pressure recorder is proportional to the input current. By adjusting the input current of proportional valve, the angle of hydraulic poppet swash plate can be changed to achieve the purpose of speed regulation.

在一定发动机速度下，电比例液压粟开度达到大，此时如希望搅拌罐的速度再上升则需要提高自动上料搅拌车底盘发动机速度。

At a certain engine speed, the electric proportional hydraulic poppy degree reaches a large value. At this time, if you want the speed of the mixing tank to rise again, you need to increase the engine speed of the chassis of the automatic feeding mixer.
