PLATE CONVEYOR Russian patent published in 2013 - IPC E21F13/08 B65G17/06 

FIELD: transport.

SUBSTANCE: proposed conveyor comprises plate belt consisting of bed secured to two pull chains with rolls rolling in guides mounted on posts, intermediate drives, each composed of endless pull chain surrounding driving and tension sprockets to allow interaction between pull chain with plate belt. Plate belt links arranged opposite each other over belt width are interconnected by "П"-like beams with replaceable straps made from resilient material and secured at their top brass arms to allow interaction with outer surface of plate belt bed. Plate chains of belt upper run are arranged to interact with roller bearings. Bearing housings of driving and tensioning sprockets and said roller bearings are arranged on the frame to displace it vertically relative to conveyor posts and to be locked thereat by screw mechanisms. Magnets are arranged in gaps between pull chains and intermediate drive plate chains with minimum clearance relative to belt bed between said sprockets. Note here that said frame with chain pull member is arranged to be displaced vertically relative to fixed guides secured on conveyor posts and spring loaded thereto by spiral contraction springs. Said springs thrust against guide brackets to displace vertically relative thereto and be locked by screw mechanisms. Note here that total stiffness of springs is taken to ensure total working force equal to the sum of bed weight and total force generated by magnets. Brackets with magnets are attached to pull circuit frame.

EFFECT: higher traction brought about by intermediate drive.
