Description

Technical Field

[0001] The utility model relates to the technical field of slag scraper accessories, in particular to a scraper plate for a slag scraper. Background Art

[0002] The main structure of the scraper includes a scraper arm with a scraper bucket and a scraper conveyor. The scraper arm controls the scraper bucket to scrape the material into the scraper conveyor track, and the scraper conveyor chain pulls the scraper plate to push the material to the high-position discharge end of the track downstream. When the scraper bucket is scraping at high speed, the material will continue to pile up at the upstream end of the conveyor track. The existing scraper plate generally adopts a flat plate design, which is perpendicular to the track surface to form a vertical surface and is driven by the chain to push the material. When the pile of material increases, when the scraper plate at this position moves, the friction between the scraped material at the bottom and the accumulated material at the top increases due to the deadweight of the material, and the travel resistance of the scraper also continues to increase. Therefore, the torque demand for the conveying motor used to drive the scraper chain continues to increase. Utility Model Content
