In order to improve the utilization rate of the chain scraper conveyor, it is basically carried at full load when it is used in the coal mining process. After a long time, it will have an adverse effect on the equipment. For example, its sprocket will wear and its The connecting ring may also be broken as a result, causing the chain scraper conveyor to fail to operate normally.
Of course, it is not possible that the chain scraper conveyor cannot work due to this factor. The scraper chain is suddenly jammed by rigid objects in the coal during operation, or misaligned at the opposite side of the chute, which will also cause the same consequences; Or when the chain scraper conveyor is in the installation stage, the tightness of the scraper chain is not well adjusted.
Judging from the reasons that cause the scraper chain conveyor to break and fail to work, in order to make the chain scraper conveyor operate normally and safely, it is necessary to strengthen the inspection and maintenance of the scraper chain and take corresponding management measures. On the one hand, it is necessary to adjust the sprocket in time to make its teeth symmetrically used; when the two sprocket wear levels are inconsistent, replace the two sprocket to balance the forces on the two chains, and the scrapers of the two chains are not inclined during operation.
On the other hand, a hydraulic coupling must be equipped in the scraper chain conveyor to reduce the impact load on the chain; when the plate chain has been used for a period of time, it can be removed and turned 90° to continue using it, and exchange the horizontal scraper chain The position of the ring and the vertical scraper chain link can be used to extend the service life of the chain by changing its wear parts.
Also, it is necessary to prevent the scraper chain of the scraper chain conveyor from being too tight or too loose; when the machine is running, it must be flat and straight to avoid sharp bends; there should be no floating coal at the bottom of its chute, and if any, it must be cleared in time to reduce The resistance of the scraper chain in operation.
