[0002] At present, the scraper conveyor is a transportation machine used in coal mining working faces, mainly used for the transportation of coal mining working faces and crossheadings in mining areas, and can also be used in driving working faces of coal roadways and semi-coal rock roadways. The scraper conveyor is also called a scraper, and is widely used in the daily mining and conveying work of coal mines. The coal mine scraper conveyor adopts an open steel trough type, which is convenient for the coal cut by the shearer to fall onto the scraper conveyor. The middle double-chain structure is adopted inside the steel trough, and wear-resistant steel plates are used for traction.

[0003] At present, when the scraper conveyor is working, it will affect the track, causing the track to vibrate, thus affecting the operation of the track, and it is prone to failure, affecting the working efficiency of the scraper conveyor. Moreover, the shock-absorbing track bears the vibration and impact of the scraper conveyor for a long time, and its service life is limited. Once the shock-absorbing track is worn or damaged, it needs to be replaced in time, otherwise it will affect the normal operation of the scraper conveyor. Content of the Utility Model
