1. Hydraulic drive system: the hydraulic system is the core system of the mixer. In order to ensure that the mixer truck can work normally and the mixing tank can operate normally, the hydraulic oil level of the oil radiator and reducer must be checked before each vehicle starts to ensure that the oil level indication is within the scope of the window. At the same time to ensure its cleanliness, so as to avoid dust particles and water pollution system hydraulic oil, resulting in the system can not work normally or damage.

2．供水系统：气压供水系统加水量一般在水箱的四分之三处为宜；车辆在行驶时水路系统中各个阀门均应处于关闭状态，以免影响车辆的制动性能，或烧结摩擦片，从而影响车辆的制动性能。禁止随意焊接和改动水箱，避免重物撞击；经常检查阀体是否堵塞或是否有工作异常；在有结冰可能的环境中使用时，供水系统必须排空存水，防止管路冻裂；经常检查系统的密封性，拆卸修理后，关键部位要涂螺纹密封胶。

2. Water supply system: the amount of water in the pneumatic water supply system is generally three fourths of the water tank; when the vehicle is running, all valves in the water system should be closed, so as not to affect the braking performance of the vehicle, or sintering friction plates, thus affecting the braking performance of the vehicle. It is forbidden to weld and change the water tank at will to avoid the impact of heavy objects; it is often checked whether the valve body is blocked or whether it works abnormally; when it is used in the environment with the possibility of icing, the water supply system must be emptied to prevent the pipeline from frost cracking; it is often checked that the sealing of the system, and the key parts should be coated with thread sealant after disassembly and repair.

3．搅拌筒：初次使用50h要及时检查罐体及其他部位螺栓是否有松动，每天行车前要检查托轮与滚道的润滑，每个月打开一次托轮护罩，清理内部的油污并添加润滑油脂。

3. Mixing drum: the bolts of tank body and other parts shall be timely checked for looseness after the first 50 hours of use. The lubrication of supporting roller and raceway shall be checked before driving every day. The supporting roller shield shall be opened once a month to clean the internal oil and add lubricating grease.

从整体来看，车辆体积小、重量轻，载重量也适合农村基础建设过程中搅拌后的水泥量小、频率高的需求特点，同时其性能可靠，灵活方便，操作简单，弥补了大型搅拌车无法进入狭窄道路的缺点，也更加低廉，同时在维修保养方面成本较低，因此使得整车从购买到使用比较经济，适应于小城镇建设、路桥建设，特别是地铁隧道、矿石巷道修补等，有较强的优越性。

On the whole, the vehicle is small in size, light in weight, and suitable for the demand characteristics of small quantity and high frequency of cement after mixing in the process of rural infrastructure construction. At the same time, its performance is reliable, safe, flexible and convenient, and its operation is simple. It makes up for the disadvantage that large mixer can not enter the narrow road, and its price is also lower. At the same time, the cost of maintenance is lower, so it makes the whole process more convenient The car is more economical from purchase to use. It is suitable for the construction of small towns, roads and bridges, especially for the repair of subway tunnels and ore tunnels.
