Abstract
A plough guide trough for plough guides of chain-drawn coal ploughs, comprising two superposed chain guide ducts separated by an integrally cast sliding spacer member, with a top guide strip, a bottom guide beam and a bottom slideway for guiding the plough. The top chain guide duct is covered by a front wall comprising the guide strip and merging into the guide beam and a slot lead-through for a plough guiding hook or plough knife is formed between the guide beam and the slideway. Pockets in the front wall receive a toggle coupling for neighboring plough guide troughs, wherein the front wall, the guide strips, the guide beam, the pockets and a back wall comprising the slideway form a one-piece casting extending over the length of the plough guide trough.
