The mobile concrete mixer is composed of chassis and special conveying equipment of concrete mixing station. Its special mechanism mainly includes power take-off, front and rear support frame of mixing drum, reducer, hydraulic system, mixing drum, control mechanism, cleaning system, etc.

移动式水泥自动搅拌车工作原理是通过取力设备将底盘的动力取出，并驱动液压系统的变量泵，把机械能转化为液压能传给定量马达，马达再驱动减速机，由减速机驱动搅拌装置，对混凝土开展搅拌。

The working principle of the mobile concrete mixer is to take out the power from the chassis through the power take-off equipment, and drive the variable pump of the hydraulic system. The mechanical energy is converted into hydraulic energy and transmitted to the quantitative motor. The motor drives the reducer, and the reducer drives the mixing device to mix the concrete.

1、移动式水泥自动搅拌车运输混凝土时，发动机功率在一千到一千四百转/分范畴内运行，在运输混凝土全过程中，速度不可超出四十公里每小时。

1. When the mobile concrete mixer transports concrete, the engine power is in the range of 1000 to 1400 rpm, and the speed shall not exceed 40 km / h in the whole process of concrete transportation.

2、移动式水泥自动搅拌车运行结束，应把搅拌筒内部结构和车体清理整洁，不可以使剩下的混凝土留到筒内。

2. After the mobile concrete mixer is running, the internal structure and car body of the mixing drum shall be cleaned up, and the remaining concrete shall not be left in the drum.

3、移动式水泥自动搅拌车在水泵运行时，严禁空转，连续应用时不要超出15分钟。

3. When the mobile concrete mixer is running, it is strictly prohibited to run idly, and the continuous application should not exceed 15 minutes.

4、移动式水泥自动搅拌车储水箱的水量要常常维持放满，以便急需，冬天停机后，应将储水箱、水泵、水管、搅拌筒内的水放净，并停到向阳、不存水的位置，以防冻坏机械设备。

4. The water storage tank of mobile concrete mixer truck should always be fully filled so as to be in urgent need. After shutdown in winter, the water in the water storage tank, water pump, water pipe and mixing drum should be drained completely, and the water should be stopped to the sunny position without water storage, so as to prevent the mechanical equipment from being damaged.

5、移动式水泥自动搅拌车在冬天应及时性安装保温套，并应用防冻液对水泥自动搅拌车加以保护，依据天气变化拆换燃油标号，确保机械设备的正常的应用。

5. In winter, the mobile concrete mixer truck should be installed with insulation sleeve timely, and the concrete mixer truck should be protected with antifreeze. The fuel label should be replaced according to the weather change to ensure the normal application of mechanical equipment.

6、在检查、维修移动式水泥自动搅拌车液压传动部分时，应以发动机和液压泵在没有压力的情况下开展。

6. When inspecting and repairing the hydraulic transmission part of mobile concrete mixer, the engine and hydraulic pump should be used without pressure.
