Abstract: An agricultural equipment air screen cleaning assembly having a frame having an airflow opening having a non-circular outer perimeter, a screen mounted to the frame within the airflow opening and extending to the non-circular outer perimeter, a motor, and a suction wand operatively connected to the motor and located on an upstream side of the screen. The suction wand is rotatably connected about a rotation axis at a central region of the screen, and includes: at least one distal end that is movable in a radial direction with respect to the rotation axis to follow the non-circular outer perimeter as the suction wand rotates about the rotation axis, one or more inlet openings facing the screen, and an internal suction flow path in fluid connection with the one or more inlet openings, the suction flow path extending from a manifold to the distal end of the suction wand.

Abstract: A concave for a harvester combine is provided, the concave comprising a first longitudinal member comprising a plurality of first longitudinal member wire guide grooves substantially at the same height position relative to a bottom of the first longitudinal member; a second longitudinal member comprising a plurality of second longitudinal member wire guide grooves substantially at the same height position relative to a bottom of the second longitudinal member; a first transverse member and a second transverse member substantially parallel to one another affixed to the first longitudinal member and the second longitudinal member; and a plurality of module members affixed to the first and second transverse members.

Abstract: A method of manufacturing a helical bar concave from a flat, rolled laser cut arrangement that provides a net helical concave functionality. Laser cutting a flat metal sheet to form helical cutouts defining a percent open area having a helical geometry in combination with configurable rub bars mounted in a helical fashion results in a configurable helical bar concave in which the number or aggressiveness of the threshing surface on the inside radius of the grate may be changed and/or the rub bars may be moved to the outside of the grate to change the percent open area and hence the separation characteristics of the concave.

Abstract: A cornhead row unit including first and second longitudinally extending stripper plates mounted on a frame and having opposed stripping edges which define a gap between them. The frame further includes an adjusting arrangement operatively connecting the frame and at least one of the first and second stripper plates to selectably and transversely move at least one of the first stripper plate and second stripper plate with respect to the other stripper plate to vary the width of the gap. A loss detection device is operatively connected to the frame for permitting measurement of corn kernels lost as a result of drawing corn stalks through the gap to separate corn ears from the stalks.

Abstract: A concave for a harvester combine and methods of use are provided, such as a concave for a combine harvester, the concave comprising a first longitudinal member comprising a plurality of first longitudinal member wire guide grooves substantially at the same height position relative to a bottom of the first longitudinal member; a second longitudinal member comprising a plurality of second longitudinal member wire guide grooves substantially at the same height position relative to a bottom of the second longitudinal member; a first transverse member and a second transverse member substantially parallel to one another affixed to the first longitudinal member and the second longitudinal member; and a plurality of module members affixed to the first and second transverse members.

Abstract: The unloader system has a conveyor and a raise system having an elongate support element including a flexible first end portion and an opposite second end, the first end portion being connected to a support structure at a location higher than a first end of the conveyor, and the second end being connected to the conveyor at a location therealong adjacent to a free end thereof. A cam element is disposed on the support structure in a path of movement of the flexible first end portion of the support element such that as the conveyor is pivoted from the stored position toward the operating position the flexible first end portion will conformingly engage or bend about the cam element to raise the free end of the conveyor. The conveyor can include an elbow which is straightened by this action for raising the free end.

Abstract: A helical bar concave including a grate having helical mounting framework and helical cutouts to form a percent open area having a helical geometry. Configurable and segmented rub bars are mounted in a helical fashion to a cylindrical helical surface of the grate. The helical geometry in combination with configurable rub bars mounted in a helical fashion results in a configurable helical bar concave in which the number or aggressiveness of the threshing surface on the inside radius of the grate may be changed and/or the rub bars may be moved to the outside of the grate to change the percent open area and hence the separation characteristics of the concave.

Abstract: The cob cleaning conveyor system provides a capability for positively removing or cleaning lighter crop residue from a flow of cobs. The system can be incorporated with a cob collection device, such as on a trailer, and can be adjustable in several ways for accommodating varying corn varieties, conditions and the like. The system includes a first conveyor which propels the flow into a gap or passage toward a second conveyor, while a flow of air is directed downwardly through the passage to remove or clean the lighter residue material from the cobs. The angle of attack of the air flow can be selectable, and optionally be directed downwardly along the second conveyor to the passage, and upwardly along the second conveyor to travel with or follow the residue flow, to suit present conditions.
