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.
A drive gear and guide arrangement for a mining machine, which operates above a chain scraper conveyor, having a guide rail arranged on a trough section of said chain scraper conveyor, on the stowing side, at a level above said trough section, said guide rail extending alongside said chain scraper conveyor forming a chain duct for a drive gear chain for the moving forward of said mining machine, said guide rail including a profile lug which engages over horizontal chain links of said drive gear chain and holds said chain links on a chain support in said chain duct, said guide rail having a rolled profile which forms a sealing strip that closes off said chain duct of the drive gear chain on the side of the conveyor, said chain duet open on said stowing side for discharge of fine material, said guide rail profiled roughly in the shape of a U-section with downward extending legs of different lengths, wherein the longer stowing side leg forms a sealing strip and in the area underneath said chain duct, said leg being fixed to said trough section or to parts attached to the latter on its stowing side by welding.
