Abstract

A scraper for a scraper chain conveyor, having a top web, on which a chain attachment region for connecting the scraper to a scraper chain is configured, and having scraper wings for guiding the scraper on side profiles and bottom of a scraper chain conveyor. In order to provide scrapers with which a higher conveying output or a reduction of the drive output to be installed can be achieved, and which also enable a worn or defective scraper to be changed below ground, it is provided according to the invention that the scraper wings consist of a holding portion anchored to the metallic top web and a plastics sliding insert which can be releasably fastened to the holding portion. For the sliding inserts and their retention, various embodiments are proposed.
