1. Mixing drum: the mixing drum used in this model is a widely used structural form. The mixing drum is pear-shaped structure. Its cleaning water and mixing water added as needed during transportation are injected into the drum from the feed inlet of the mixing drum head.

2、传动系统：该搅拌筒的驱动方式为以发动机为动力源，由发动机后端的取力器取力，通过传动轴传递到变量柱塞液压泵，经定量柱塞油马达，再通过减速机带动搅拌筒转动。

2. Drive system: the mixing drum is driven by the engine as the power source. The power is taken from the power take-off at the rear end of the engine and transmitted to the variable piston hydraulic pump through the transmission shaft. The mixing drum is driven to rotate through the quantitative piston oil motor and the reducer.

3、搅拌筒的进出料系统（装料和卸料机构）：是辅助搅拌筒工作的重要装置。

3. Feeding and discharging system of mixing drum (loading and unloading mechanism): It is an important device to assist the mixing drum.

4、操纵系统：是整个搅拌车的控制部件，操纵面板上开有“工字形”槽，是操纵杆的活动空间；并且后半部的槽上开有限位孔，用来固定操纵杆的位置。该操纵系统通过汽车尾部的左右两个操纵杆来控制搅拌筒的正、反转和转速，从而来完成进出料以及搅拌动作。

4. Control system: it is the control part of the whole mixing truck. There is a "I-shaped" slot on the control panel, which is the active space of the control lever; The slot in the rear half is provided with a limit hole to fix the position of the joystick. The control system controls the forward, reverse and rotational speed of the mixing drum through the left and right control levers at the rear of the car, so as to complete the feeding and mixing actions.

5、供水系统：混凝土搅拌车的供水系统主要用来清洗搅拌装置。该车型的供水系统共有两种型式，一种是离心水泵供水系统；一种是压力水箱供水系统，可供用户选装。

5. Water supply system: the water supply system of the concrete mixer is mainly used to clean the mixing device. There are two types of water supply system for this vehicle, one is centrifugal pump water supply system; One is the pressure water tank water supply system, which is optional for users.
