The belt conveyor has the advantages of strong conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient programmed control and automatic operation. Since the loading mixer truck and concrete mixing plant can not lack belt conveyor, the belt conveyor can be used to transport materials. Therefore, during use, attention should also be paid to maintenance.

1、传动装置的维护与保养。使用前应加润滑油，润滑油牌号为LKC100，150#中负荷极压工业齿轮油。

1. Maintenance of transmission device. Lubricating oil shall be added before use. The brand of lubricating oil is lkc100150# medium load extreme pressure industrial gear oil.

2、滚简轴承的润滑。滚简轴承为UCP系列(常用UCP214)，用润滑脂润滑，每天加油一次。

2. Lubrication of roller bearings. The plain roller bearing is UCP series (commonly used ucp214), which is lubricated with grease and filled once a day.

3、滚简与托辊的清理。自上料搅拌车，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。自上料搅拌车

3. Cleaning of roller and idler. From the feeding mixer truck, the accumulated materials on the roller and idler are often cleaned. Too much accumulated materials will affect the operation of the belt and lead to deviation. Self loading 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 scraper, and replace the sand scraper in time after it is worn to a certain extent.

5、自上料搅拌车，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. Replacement of rubber retaining edge of self loading mixer. The rubber retaining edge is seriously worn, and it shall 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。自上料搅拌车，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. When using the self loading mixer truck, the load shall be reduced as far as possible, 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.
