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

移动式自上料混凝土搅拌罐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 of the chassis through the power take-off equipment, drive the variable displacement pump of the hydraulic system, convert the mechanical energy into hydraulic energy and transfer it to the quantitative motor, then the motor drives the reducer, and the reducer drives the mixing device to mix the concrete.

移动式自上料混凝土搅拌罐车运输混凝土时，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。

When the mobile concrete mixer transports concrete, the engine power is in the range of 1000 to 1400 rpm. During the whole process of transporting concrete, the speed should not exceed 40 km / h.

移动式自上料混凝土搅拌罐车运行结束，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。

At the end of the operation of the mobile concrete mixer, 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.

移动式自上料混凝土搅拌罐车在水泵运行时，严禁空转，连续应用时不要超出15分钟。

When the water pump of the mobile concrete mixer is running, it is strictly forbidden to idle, and the continuous application shall not exceed 15 minutes.

移动式自上料混凝土搅拌罐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。

The water storage tank of the mobile concrete mixer should always be kept full so that it is in urgent need. After shutdown in winter, the water in the mixing drum of the water pump and water pipe of the water storage tank should be drained and stopped to the sunny position without water storage, so as to prevent freezing and damage the mechanical equipment.

移动式自上料混凝土搅拌罐车在冬天应及时性安装保温套，并应用防冻液对自上料混凝土搅拌罐车加以保护，依据天气变化拆换燃油标号，确保机械设备的正常的应用。

In winter, the mobile concrete mixer should be timely installed with insulation sleeve, and antifreeze should be applied to protect the concrete mixer, and the fuel label should be removed and replaced according to the weather change, so as to ensure the normal application of mechanical equipment.

在检查维修移动式自上料混凝土搅拌罐车液压传动部分时，应以发动机和液压泵在没有压力的情况下开展。

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