Automatic concrete mixer. The belt conveyor has the advantages of strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can easily implement programmed control and automatic operation. Full automatic concrete mixer and concrete mixing plant can not lack belt conveyor, and use belt conveyor to transport materials, etc. Therefore, attention should also be paid to maintenance when using.
1、传动装置的维护与保养。使用前应加润滑油
1. Maintenance of transmission device. Add lubricating oil before use
2、滚简轴承的润滑。用润滑脂润滑，每天加油一次。
2. Lubrication of roller bearings. Lubricate with grease and add oil once a day.
3、滚简与托辊的清理。全自动混凝土搅拌车，经常清理滚简和托辊上的积料，积料过多会影响皮带的运行，出现跑偏的情况。全自动混凝土搅拌车
3. Cleaning of roller and idler. The full-automatic concrete mixer often cleans the accumulated materials on the roller and idler. Too much accumulated materials will affect the operation of the belt and lead to deviation. Automatic concrete mixer
4、刮砂装置的维护。定期检查刮砂装置的磨损程度，刮砂装置磨损到一定程度后及时更换。
4. Maintenance of sand scraper. Regularly check the wear degree of the sand scraping device, and replace the sand scraping device in time after it is worn to a certain extent.
5、全自动混凝土搅拌车，橡皮挡边的更换。橡皮挡边磨损严重，有料撒出时应及时更换。
5. Automatic concrete mixer, replacement of rubber retaining edge. The rubber retaining edge is seriously worn and should be replaced in time when materials are scattered.
6、接口断裂及横向撕裂的防范及处理。接头硫化处理不合格;冲击负载过大，薄弱部分受交变应力影响断裂;接口方向与皮带运动方向不合适；长期使用等，严重损坏皮带。全自动混凝土搅拌车，在使用时要尽量减少负载，特别是有配重张紧装置的皮带，应控制配重在200kg~300kg内，以雨季不打滑为宜，加强巡查，防止异物卡死皮带，划伤皮带;加强对皮带装配人员的培训，防止皮带接口方向装反。
6. Prevention and treatment of interface fracture and transverse tear. The joint vulcanization treatment is unqualified; The impact load is too large, and the weak part breaks under the influence of alternating stress; The interface direction is not suitable for the belt movement direction; If it is used for a long time, the belt will be seriously damaged. The full-automatic concrete mixer shall minimize the load when in use, especially the belt with counterweight tensioning device. The counterweight shall be controlled within 200kg ~ 300kg, and it is better not to slip in rainy season. Patrol inspection shall be strengthened to prevent foreign matters from blocking the belt and scratching the belt; Strengthen the training of belt assembly personnel to prevent reverse installation of belt interface.
