ABSTRACT:
A plough guide which is built onto the runs of channelling of a scraper chain conveyor, has angle plates which form a slide path for the plough and which are connected by their upwardly extending sides to the runs of channelling. Sliding spacers are provided behind a covering between an upper chain channel and a lower chain channel. Covering hoods which form the covering for the channels are each pivotably mounted to a lower guide beam. The hoods can be swung over on the pivot joints towards the face in order to open the upper chain channel. The spacers are connected to the angle plates via fitting plates which are rigidly connected thereto and which extend upwards beyond the spacers. The fitting plates are provided with centering pins which engage centering apertures in the angle plates. The fitting plates can be connected to the sliding spacers and/or the angle plates by welding.
