Abstract

A conveyor and guide assembly comprises a conveyor and a plough guide attached to one side of the conveyor. The conveyor comprises a plurality of conveyor sections joined end-to-end, and the guide comprises a plurality of guide sections positioned end-to-end. Each guide section is associated with, and extends substantially along, a corresponding conveyor section. The guide section has a generally L-shaped guide plate and a ramp-like cover plate which define therebetween upper and lower chain ducts for receiving a plough drive chain. Each section of the cover plate is curved over at the top towards the guide plate thereby delimiting the upper portion of the upper chain duct. Each adjacent pair of cover plate sections overlap in a first zone which extends over at least the curved-over portions thereof. Each pair of adjacent sections of the guide plate overlap in a second zone which adjoins said first zone. The gap between each pair of adjacent guide plate sections is longitudinally off-set from the corresponding gap between adjacent conveyor sections in a third zone which is adjacent to said second zone.
