Abstract: A scraper for use on a scraper chain conveyor, the scraper having an upper element and a lower element. A chain bed for receiving at least one horizontal chain link and at least one vertical chain link is formed in both upper and lower elements. The upper element and lower element are connected together by means of form-fit surfaces provided on the upper element and the lower element, such that these form-fit surfaces engage with each other when the two elements are assembled for operation to form a form-fit lock. A chain link presses from behind against the lower element or the upper element of the scraper in the direction of transport and this force reinforces the form-fit lock between the two elements.
