Abstract
A conveyor structure (1.20) is disclosed that is capable of being retracted concertina fashion for transport on a trailer (42) between sites of operation. The structure comproses a plurality of H-frames each comprised of rigid supports (2A, 2B or 21,22) joined by a cross-member (3) which supports rollers (3A-D,30) upon which the conveyor belt (4) travels. Extensible links (6), and cross-braces (25,26) maintain the longitudinal and lateral rigidity of structure.
Claims12
A conveyor structure comprising:
- a set of H-frames each comprising two substantially parallel rigid supports of equal length, and a cross-member arranged to support a conveyor belt, said H-frames being pivotally joined together in zig-zag configuration with corresponding ends of each of said rigid supports being pivotally connected, the pivot joining of said H-frames comprising a pivot axis displaced from the plane of each joined H-frame, wherein said set of frames is able to extend and retract in concertina fashion between a compact transport configuration in which the rigid supports of adjacent frames are substantially parallel and an extended zig-zag support configuration, the angular separation between adjacent frames being limited by a plurality of links extending between said frames.
A conveyor structure comprising:
- a set of H-frames each comprising two substantially parallel rigid supports of equal length, and a cross-member arranged to support a conveyor belt, said H-frames being pivotally joined together in zig-zag configuration with corresponding ends of each of said rigid supports being pivotally connected wherein each said rigid support is adapted for engagement with a surface over which said structure is operatively arranged and said set of frames is able to extend and retract in concertina fashion between a compact transport configuration in which the rigid supports of adjacent frames are substantially parallel and an extended zig-zag support configuration, the angular separation between adjacent frames being limited by a plurality of links extending between said frames, wherein said cross members are mounted to said rigid supports using an adjustable slide on a bracket to provide for training of said conveyor belt.
