Abstract
A bladed pulley including a plurality of blades extending from a first end to a second end. The bladed pulley having spaced apart blades and an open, central volume configuration to permit conveyed material to fall through the pulley. The bladed pulley further having an orienting structure designed to radially orient and position each of the blades about a longitudinal axis.
Claims18
A pulley for use with a conveyor belt, the pulley comprising:
- (a) a first end, a second end, and a longitudinal axis extending between the first and second ends;
- (b) a first hub and a second hub positioned at corresponding first and second ends of the pulley, the first and second hubs being coaxially aligned with the longitudinal axis of the pulley;
- (c) at least a first orienting member, the first orienting member including:
- (i) a central portion aligned with the longitudinal axis;
- and
- (ii) a plurality of slots radially extending from the central portion;
- (d) a plurality of blades, each of the blades including:
- (i) a first end mounted proximate the first hub;
- (ii) a second end mounted proximate of the second hub;
- and
- (iii) an intermediate section located between the first end and the second end, the intermediate section being positioned within one of the plurality of slots of the first orienting member, each of the blades being oriented to radially extend outward from the longitudinal axis of the pulley;
- and
- (e) a central volume defined within inner edges of the plurality of blades and the first and second hubs, the central volume being free of obstructions extending between the first hub and the second hub.

A pulley for use with conveyor systems, the pulley comprising:
- (a) a first rotary arrangement;
- (b) a second rotary arrangement positioned opposite the first rotary arrangement;
- (i) the first and second rotary arrangements defining first and second ends of an open volume of the pulley;
- (c) a plurality of blades radially projecting from the open volume, the blades being supported at opposite ends by the first and second rotary arrangements;
- and
- (d) a first axle supported by the first rotary arrangement and a second axle supported by the second rotary arrangement, the first and second axles extending only externally of the open volume of the pulley.

A conveyor system comprising:
- (a) a plurality of pulleys, including a drive pulley and an idler pulley, the pulleys including:
- (i) a first end and a second opposite end;
- (ii) a longitudinal axis extending from the first end to the second end;
- (iii) a plurality of blades extending in a radial direction from the longitudinal axis;
- (iv) a center volume defined within the plurality of blades and between the first and second ends;
- (v) a first axle arranged to rotationally support the first end of the pulley, the first axle extending only outward from the center volume;
- (vi) a second axle arranged to rotationally support the second end of the pulley, the second axle extending only outward from the center volume;
- and
- (b) a belt for conveying material, the belt circumscribing the plurality of pulleys.
