1. During the initial operation of the scraper conveyor, attention should be paid to checking the tightness of the scraper chain, as the connection between the chutes will reduce the spacing due to operation. If the chain is too loose, there may be accidents such as chain jamming, chain jumping, chain breakage, and chain falling. The inspection method is to reverse the conveyor and count the number of slack links. If there are more than two slack links, it is necessary to tighten the chain again.
2. Keep the working surface straight. If the working surface is not straight, the tension between the two chains will be unequal, resulting in uneven chain wear or causing the bottom chain to fall off, get stuck, or break.
3. The bending of the scraper conveyor should be appropriate, and there should be no "sharp bends". The bending part should be no less than eight sections of the chute. When moving, attention should be paid to the coordination of the front and rear hydraulic jacks to avoid sharp bends. Otherwise, the chute will be staggered, causing chain breakage and chain drop accidents. Special attention should be paid to not moving the scraper conveyor when it is stopped.
4. The scraper conveyor should be laid flat. Due to the limitations of the chute structure, it can only adapt to changes in the vertical direction of 3-5. Therefore, if there are local bumps in the working face bottom plate, it should be leveled. Moreover, the smooth laying of the scraper conveyor is conducive to the operation of the scraper chain, reducing the wear of the chute and reducing power consumption.
5. During blasting, protect the transmission parts, pipelines, unit cables, switches, etc. of the scraper conveyor. When transporting iron and long materials with a scraper conveyor, measures should be taken to avoid personal accidents.
6. The overlap between the tail of the transition slot and the intermediate slot should not have excessive bending, and if there is any bending, it should be padded with wood.
7. Pay special attention to the vibration of the coupling, and check the vibration of the hydraulic coupling when the scraper conveyor is started. In order to protect good heat dissipation conditions, it is necessary to frequently clean the protective cover and liquid.
