A diversion assembly for use with a feed material. The diversion assembly includes a plurality of movable gate chutes, a first conveyor, and a second conveyor. The plurality of movable gate chutes are each positionable in a retracted position and an extended position. The first conveyor is configured to carry, for each of any of the plurality of movable gate chutes in the retracted position, a first portion of the feed material to a first area. The second conveyor is configured to carry, for each of any of the plurality of movable gate chutes in the extended position, a second portion of the feed material to a second area. The second area is spaced apart from the first area.

Repaired combine augers are provided that can include: a central cylindrical object configured to support flighting extending about the central cylindrical object, wherein at least one portion of the flighting is damaged and defines non-linear portions, openings, and/or bent sections; and at least one semi-circular repair component bound to the portion to align with remainder of the flighting.

A telescoping rotatable tool includes a first shaft and a second shaft. The first shaft has a first material-engaging element extending from an exterior surface of the first shaft. The second shaft has a second material-engaging element extending from an exterior surface of the second shaft. The second shaft is configured to extend from and retract within an interior space presented by the first shaft. The first shaft includes at least one helical-shaped groove extending along an interior surface of the first shaft. The second shaft includes at least one guide element extending from the exterior surface of the second shaft. The guide element is configured to engage with the groove, such that as the second shaft extends from and retracts within the first shaft, the second shaft is configured to rotate with respect to the first shaft.

Methods for repairing a damaged combine auger are provided. The methods can include: identifying at least one damaged portion of flighting of the auger; and coupling at least one semi-circle repair component to the damaged portion of the flighting to provide a linear edge continuous with remainder of the flighting.

A combine harvester tailings return system includes a tailings conveyor and an ejection channel for depositing tailings upstream of a cleaning system. A proximity sensor is mounted to the ejection channel and is configured to sense the height of a layer of tailings during transit through the returns system.

A screw conveyor based fabric dyeing machine including a machine body inside which a screw conveyor including a conveying screw and a fabric support board is arranged and generally parallel to an extension direction of the machine body. Fabric moves through a dyeing tube arranged with the machine body to fall down onto the screw conveyor so that the fabric can be conveyed by the screw conveyor forward through the machine body to reach a guide roller and a nozzle to complete a cycle of circulation for subsequently re-entering the dyeing tube to be dyed therein. As such, water consumption can be reduced and dyeing performance is enhanced, achieving energy saving and carbon reduction, reducing contamination to the surroundings, and realizing green economy.

A screw conveyor to convey powdery material, in particular cement. The screw conveyor comprises: a transfer screw; and a trough containing the transfer screw; the trough being provided with an inlet section and an outlet section of the powdery material. The screw conveyor is characterized in that the screw comprises: at least a first screw portion having a first law of continuous variation of the pitches of the screw, which can be graphically represented by means of a first function having in at least one stretch a first derivative other than zero; and at least a second screw portion having a second law of continuous variation of the pitches of the screw, which can be graphically represented by a second function having in at least one stretch a first derivative other than zero. The first law of continuous variation of the pitches is different from the second law of continuous variation of the pitches.

A continuous motion position controlled in-line linear seamer allows a manufacturer or brewery such as a microbrewery to have high speed can seaming (attachment of lids to full cans of beverage) with a single compact, inexpensive, independent and repositionable seaming machine. The seaming is carried out in-line with production, and is done using a linear can path with no need for a large carousel. The motion is continuous because a variable pitch worm drive is constantly operating, driving cans at different speeds for different portions of the can path, including one portion of the path at which the can may remain motionless while being seamed.
