| 摘要 |
The invention relates to scrapers (10) for link chains of in particular double-centre scraper chain conveyors, comprising a single-part scraper body with a top crosspiece (2), which connects two lateral scraper blades (1), and at least one insertion pocket (5) for the insertion of a horizontal chain link (52) of the link chain and securing of the scraper (10) by means of a releasable scraper-securing element (40). In order to improve the carrying-along action of the scrapers (10) connected to the horizontal chain links, and also for it to be possible to use the scrapers with new types of link chains, grooves extend in the insides (11) of the scraper blades (1) and outsides of an intermediate crosspiece (6), over the height of the leg bases (15), up to the top crosspiece (2) and form mounts for carry-along protrusions (58) on the outer surfaces of the legs (56) of the horizontal chain links (52). The invention also relates to the scraper-securing element (40). |
