Abstract
A drive (D) for an auger conveyor (FC) is disclosed where the auger conveyor comprises a conveyor conduit (11) and a centerless helical coil auger (15) disposed within the conduit. The auger has a longitudinal axis and a plurality of spaced, helical flights (17). The drive (D) is a drive screw (23) substantially coaxial with the auger and having a plurality of flights in face-to-face engagement with corresponding flights of the auger. A drive member (47) is in driving engagement with the drive screw with the drive screw and the drive member being mounted for rotation about the longitudinal axis. A power drive (27) is rotatably drives the drive screw about its longitudinal axis so as to effect movement (either axial or rotational movement) of the auger relative to the conveyor conduit. A method of driving the auger is also disclosed.
