ABSTRACT:
A conveying trough for chain scraper conveyors, comprises a plurality of trough sections for the conveyance of the material each having side walls including a guide plate which has a portion adjacent an end thereof with a recess forming a pocket on the interior side of the guide plate. The guide plate has at least one projection extending into the pocket and a link plate is disposed in the pockets of adjacent plates and has eyelets into which the respective projections extend with a clearance between the guide plates and the link plate. A locking plate is arranged to overlie the link plate. Each guide plate is provided with a guide rail at its top which forms a surface defining a trackway for a wheel of a cutter or similar machine which runs over the conveying trough. The cutter has a hold-down member which engages beneath an inwardly extending claw portion of the guide rail and it has a slide surface which engages with a similar slide surface on the underside of the claw portion. The locking plate and the link plate form an insert bridge between adjacent sections and this insert bridge has a bridge rail section which runs between the guide rails.
