Underground, scraper conveyors are used for the removal of coal. In this case, the scrapers are screwed to the round link chain. These scrapers are struck from one piece in the forging die, each scraper being suitable only for the respective conveyor type, that is to say guide shape, width and chain arrangement are different. Furthermore, when the scraper becomes worn, the entire scraper must be removed. In addition, the scraper can be fitted or removed only at the chain sprocket. The invention provides a scraper which has a modular form and the parts comprise a central part, two side profile guides and a clamping rail. This is held together by two connecting screws. The special advantage in the rotatable Hirth displacement of the exchangeable side profile guides. By exchanging the side profile guides, the scraper can be used for several scraper conveyor types and widths, as well as with different round link arrangements. In the case of wear, only the side profile guides must be exchanged. Repair, transport and stock keeping costs are considerably reduced by the use of this scraper.
