Chain scraper conveyor

摘要

The invention relates to a chain scraper conveyor having a chain which is moved in the conveying direction in a conveying trough (2) and is connected to scrapers (5) which run transversely to the conveying direction and have a rectilinear lower edge, which slides on the plane trough bottom (2), and, at both ends, guide sections which are guided in a positive-locking manner on the edges of the conveying trough (2). In order, in such a chain scraper conveyor, to reduce the frictional losses occurring during the conveying operation, the invention proposes that the rectilinear lower edge (6) of the scraper (5) and the plane trough bottom (2) extend as far as the outermost edge of the open trough cross-section and that the inclined guide surfaces (4, 7) of the conveying trough (1) and of the scraper (5) directly adjoin the rectilinear lower edge (6) of the scraper (5) or the plane trough bottom (2) so as to form an acute angle ( alpha ) in each case. <IMAGE>
