[0002] A scraper conveyor is a conveyor that uses a scraper chain to transport bulk materials within a trough. A scraper conveyor with its body curved at a 90-degree angle at the intersection of the working face and the transport roadway is called a "corner scraper conveyor." In modern coal mining faces, the scraper conveyor not only transports coal and materials but also serves as the running track for the coal mining machine, making it an indispensable piece of equipment in modern coal mining technology. Continuous operation of the scraper conveyor is essential for normal production. Otherwise, the entire coal mining face will be shut down, causing a production interruption.
[0003] Existing scraper conveyors have a fixed conveying height, which is inconvenient to adjust, and material tends to accumulate at the hopper. Therefore, a new technical solution is needed to address this issue. Utility Model Content
