混凝土自上料搅拌机可装运由搅拌厂生产的混凝土或按配比混合的骨料（砂、石子）、水泥和水，在运输过程中，不断对湿料慢慢搅拌，防止混凝土在运输过程中初凝和离析。混凝土自上料搅拌机由汽车底盘和混凝土搅拌运输专用装置组成，其专用机构主要包括取力器、搅拌筒前后支架、减速机、液压系统、搅拌筒、操纵机构、清洗系统等。
The concrete self loading mixer can transport the concrete produced by the mixing plant or the aggregate (sand, stone), cement and water mixed according to the proportion. During the transportation, the wet materials are continuously mixed slowly to prevent the initial setting and segregation of the concrete during the transportation. The concrete self loading mixer is composed of automobile chassis and special equipment for concrete mixing and transportation. Its special mechanism mainly includes power take-off, front and rear supports of mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system, etc.
一 清洗要点：
1. Cleaning points:
1、自上料搅拌机每次装料前用水冲洗进料口，使进料口在装料时保持湿润；
1. From the feeding mixer, flush the feeding port with water before each loading to keep the feeding port moist during loading;
2、在装料的同时向随车自带的清洗用水水箱中注满水；
2. At the same time of loading, fill the cleaning water tank with water;
3、下次装料前切记放掉混凝土贮罐内的污水；
3. Remember to discharge the sewage in the concrete storage tank before the next loading;
4、每天收工时彻底清洗混凝土贮罐及进出料口周围，保障不粘有水泥及混凝土结块；
4. At the end of each day, the concrete storage tank and the surrounding of the material inlet and outlet shall be thoroughly cleaned to ensure that there is no cement and concrete caking;

Cleaning points and operation precautions of concrete self loading mixer
5、自上料搅拌机装料后冲洗进料口，洗净进料口附近残留的混凝土；
5. Flush the inlet after the charging mixer is charged, and clean the residual concrete near the inlet;
6、到工地卸料后，冲洗出料槽，然后向混凝土贮罐内加清洗用水30-40L；在车辆回程时保持混凝土贮罐正向慢速转动；
6. After unloading at the construction site, wash the discharge chute, and then add 30-40l of cleaning water into the concrete storage tank; When the vehicle returns, keep the concrete storage tank moving in a positive and slow direction;
二 操作注意事项：
2. Operation precautions:
1、起动自上料搅拌机之前，应把搅拌筒操作手柄放在“停止”位置；
1. Before starting the self feeding mixer, put the operating handle of the mixing drum at the "stop" position;
2、自上料搅拌机起动发动机后，应使搅拌筒在低速下转动10分钟左右，使液压油温升到20℃以上后方可工作；
2. After starting the engine of the feeding mixer, the mixing drum should be rotated at a low speed for about 10 minutes to make the hydraulic oil temperature rise to more than 20 ℃;
3、自上料搅拌机在露天停放时，装料前应将搅拌筒反转，将积水和杂物排出，以保障混凝土的质量；
3. When the self loading mixer is parked in the open air, the mixing drum should be reversed before loading to discharge the water and sundries, so as to ensure the quality of concrete;
4、自上料搅拌机在运输混凝土时，要保障滑斗放置牢固，防止因松动造成摆动，在行进中打伤行人或影响其它车辆正常运行带爬山机的噪声。
4. When transporting concrete, the self feeding mixer shall ensure that the sliding bucket is firmly placed to prevent swing caused by looseness, hurting pedestrians or affecting the normal operation of other vehicles, and the noise of mountain climbing machine.
