[0038] The utility model provides a connecting plate 501, a discharge plate A502, a discharge plate B503 and a scraper bar 504, wherein the scraper bar 504 can scrape off the coking coal attached to the rotating conveyor belt on the conveyor body 4, and the scraped coking coal can be discharged along the discharge plate B503 and the discharge plate A502 to enter the subsequent coking equipment, thereby solving the problem that part of the coking coal adheres to the conveyor belt, resulting in that this part of the coking coal cannot be added to the coking, and the amount of coking coal is changed.

[0039] Specifically, a material blocking plate 3 is fixedly provided at the bottom discharge end of the silo 2, and a gap is left between the bottom end of the material blocking plate 3 and the conveyor belt of the conveyor body 4, so as not to affect the conveyor belt conveying the coking coal. The material blocking plate 3 blocks the coking coal discharged from the bottom discharge end of the silo 2, and the discharged coking coal will not jump out.

[0040] Furthermore, a fixed block A505 is fixedly provided on the bottom side of the high end of the discharge plate A502, and a fixed block B506 is fixedly provided on the bottom side of the high end of the discharge plate B503. A threaded rod 507 is threadedly passed through the fixed block A505, one end of the threaded rod 507 is rotatably connected to the fixed block B506, and a rotating handle 508 is fixedly provided on the other end of the threaded rod 507.

[0041] The utility model has the advantages of adjusting the position of the discharge plate B503 relative to the discharge plate A502 by setting a fixed block A505, a fixed block B506, a threaded rod 507 and a rotating handle 508, and adjusting the distance between the scraper strip 504 and the conveyor belt after the scraper strip 504 is worn and affects the scraping, so that the scraper strip 504 has the advantage of a long service life.
