Auger conveyors most commonly employed in industries where the horizontal and/or vertical transfer of solids or semi-solid materials is required. Auger conveyors employ a rotating helical screw blade, commonly known as flighting, which rotates about on an inline axis within an inline conduit. Described herein is an auger conveyor which does not need to follow the traditional rule of rotating about on an inline axis. A flexible wire rope shaft is employed to rotate about on an infinite number of axes thereby facilitating an auger conveyor connected to the flexible wire rope shaft through buttons, to traverse a non-linear path.

A transport device for conveying a flowable material, comprises a screw conveyor for collecting the fluid from a collecting zone and transporting the fluid to a destination zone. The screw conveyor comprises a spiral which is wound around a shaft extending along a longitudinal axis and an outer casing which at least partly houses the spiral. The spiral has a plurality of turns. The outer casing has an inner surface facing respective head surfaces of at least some turns. Between two consecutive turns and the outer casing there is a compartment. The outer casing is made at least partly from a deformable polymeric material in such a way that the outer casing deforms radially and reversibly towards the outside when a solid particle of the flowable material conveyed by the spiral is interposed between a head surface of one turn and the inner surface of the outer casing, to allow the solid particle to be transferred from one compartment to a further compartment adjacent to said compartment passing between the head surface of the turn and the inner surface of the outer casing.
