[0002] Scraper conveyors are transport machinery used in coal mine working faces. They are mainly used for transporting coal in working faces and mining area roadways, and can also be used in coal roadways and semi-coal-rock roadway excavation faces. To improve the service life of scraper conveyors, the central trough is generally made of wear-resistant trough sides. After long-term use, wear will occur, and the central trough needs to be replaced to ensure that the scraper conveyor can operate normally.

[0003] The existing technology discloses a wear-resistant trough for scraper conveyors, but its weakness in coal mining operations lies in wear. Transporting millions of tons in longwall mining will undoubtedly cause severe wear. The existing technology discloses a trough structure in the middle of a scraper conveyor, such as... Figure 8 As shown, the scraper conveyor adopts an integral design with a trapezoidal trough structure. The chain experiences severe wear during operation, resulting in high energy consumption. The central trough of the scraper conveyor suffers severe wear due to the prolonged sliding of materials, scrapers, and chains, causing the scraper conveyor to malfunction. The cost of the central trough accounts for about 60% of the total cost of the scraper conveyor. Furthermore, traditional scraper conveyors use an integral casting for the central trough, which requires replacement of the entire structure when wear is severe, leading to high costs.

[0004] In view of the above factors, it is necessary to study a wear-resistant groove plate for scraper conveyors to increase the wear resistance of scraper conveyors and thus increase their service life. Utility Model Content
