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.
A drive for an auger conveyor, said auger conveyor comprising a conveyor conduit and a centerless auger disposed within said conduit, said auger having a longitudinal axis and a plurality of flights spaced apart from one another at generally equal intervals along said longitudinal axis, said drive comprising a drive member in driving engagement with said auger for driving said auger in axial direction relative to said drive and relative to said conveyor conduit, said drive member being rotatably driven about an axis parallel to said longitudinal axis of said auger, and a power drive for rotating said drive member about said axis such that rotation of said drive member effects axial movement of said auger relative to said conveyor conduit.
