<p>In one aspect, an elevating conveyor (10) includes a vertical elevating member (26) having a helical flight (30) and a tubular barrel (32) surrounding the elevating member (26). The tubular barrel (32) is rotatable relative to the elevating member (26) and is directed toward a centered position with respect to the elevating member (26) by a centering assembly (70). In one embodiment, the centering assembly (70) includes a plurality of rollers (72a, 72b, 72c) spaced circumferentially around the barrel (32) and being movable in directions toward or away from the barrel (32). In another aspect, the conveyor (10) has a modular construction that facilitates storage, transportation, and assembly of the conveyor (10) in various heights. The elevating conveyor (10) may further include a dust tube (112) surrounding the barrel (32) and defining a chamber (120) therebetween. An end cap (114) extends over and is spaced from the second end (112b) of the dust tube (112) to define a gap (118) through which dust generated by operation of the conveyor (10) is drawn into the chamber (120).</p> |
