ABSTRACT:
A drive gear and guide arrangement for a mining machine such as a disk shearer which operates above a chain scraper conveyor. The guide arrangement includes a guide rail arranged on a trough section of the chain scraper conveyor and extends along side of the chain scraper conveyor forming a chain duct for a drive gear chain which moves the mining machine along the conveyor. The guide rail includes a profile lug which engages over the horizontal chain links of the drive gear chain and holds the chain links on a chain support in the chain duct. The guide rails also includes a rolled profile which forms a sealing strip that closes off the chain duct of the drive gear chain on the side of the conveyor. The chain duct includes opening on the storing side which are designed to discharge fine materials which enter the trough section.
