Abstract:
A trough pan with an upper strand trough and to an upper strand trough for a trough pan of a scraper chain conveyor, with two side profiles, and with a trough bottom. The trough bottom has two side edges and two end edges which have at least partially a wavy boundary line and which are provided at the transition of a top side into the end edge with a chamfer having a chamfer angle. In order to improve the upper strand troughs and the trough pans equipped with these in terms of the problem of the penetration of fine coal into the intermediate gap of the bearing region between the trough bottom and intermediate bottom, the end edges are provided with a bevel between the chamfer and an underside, the bevel sloping more steeply than the chamfer.
