Abstract
A bulk-handling belt conveyor has a flat belt having reinforced edges which cooperate with guides in such a way that the conveyor belt is formed at least into a trough and preferably a tube of circular cross section. A twisted, or spiral undriven, belt which is entrained within the trough or tube of the driven conveyor belt through frictional or interlocking engagement therewith. In this way, a belt conveyor is provided which is suited both for horizontal conveying and for conveying over inclined paths that are steeper than the angle of repose of the bulk material, has high handling capacity and results in little attrition of the bulk material.
Claims8
A bulk-handling belt for a conveyor, comprising:
- a flat conveyor belt having reinforced edges cooperative with guiding means of the conveyor for at least substantially closing the conveyor belt on itself along the reinforced edges into at least a trough of generally-circular cross section at least along a material-conveying run of the conveyor belt;
- and
- a twisted, or spiral belt disposed along the flat conveyor belt and arranged to be substantially enclosed and entrained by the flat conveyor belt when said flat conveyor belt is substantially closed thereabout.
In a belt conveyor having frame means for disposing and driving the belt conveyor between bulk-material pickup and discharge points, the improvement comprising:
- an endless, flat conveyor belt having reinforced edges;
- guide means on the frame cooperative with the reinforced edges for substantially closing the conveyor belt on itself along the reinforced edges into a tube of generally circular cross-section at least along a run of the conveyor belt from the bulk-material pickup point to the discharge point, whereby the belt conveyor is adapted for steeply conveying the bulk-material, and less-substantially closing the same into no more than a trough of generally circular section at the bulk-material pickup and discharge points for bulk-material pickup and discharge;
- and
- an endless twisted or spiral belt disposed along the flat conveyor belt for being in the trough thereof and enclosed by the tube thereof and entrained thereby.
