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、傳動裝置的維護與保養。使用前應加潤滑油

1. Maintenance of transmission device. Add lubricating oil before use

2、滾簡軸承的潤滑。用潤滑脂潤滑，每天加油一次。

2. Lubrication of roller bearings. Lubricate with grease and add oil once a day.

3、滾簡與托輥的清理。全自動混凝土攪拌車，經常清理滾簡和托輥上的積料，積料過多會影響皮帶的運行，出現跑偏的情況。全自動混凝土攪拌車

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、刮砂裝置的維護。定期檢查刮砂裝置的磨損程度，刮砂裝置磨損到一定程度后及時更換。

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、全自動混凝土攪拌車，橡皮擋邊的更換。橡皮擋邊磨損嚴重，有料撒出時應及時更換。

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、接口斷裂及橫向撕裂的防范及處理。接頭硫化處理不合格;沖擊負載過大，薄弱部分受交變應力影響斷裂;接口方向與皮帶運動方向不合適；長期使用等，嚴重損壞皮帶。全自動混凝土攪拌車，在使用時要盡量減少負載，特別是有配重張緊裝置的皮帶，應控制配重在200kg~300kg內，以雨季不打滑為宜，加強巡查，防止異物卡死皮帶，劃傷皮帶;加強對皮帶裝配人員的培訓，防止皮帶接口方向裝反。

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.
