Abstract: A sieve assembly for use within an agricultural harvester may generally include a sieve, a crop material sheet, and at least one support element. The sieve extends along a length defined between a first sieve end and a second sieve end and processes a flow of harvested crop material. The sieve also defines a plurality of openings through which cleaned crop material of the flow of crop material is directed. The crop material sheet extends along a length defined between a first sheet end and a second sheet end and receives the cleaned crop material directed through the sieve's openings. The crop material sheet then directs the flow of cleaned crop material towards a separate component of the crop processing system. In addition, the support element(s) is directly coupled between the sieve and the crop material sheet and structurally connects the sieve to the crop material sheet.

Abstract: A cleaning system for a combine harvester having an adjustable throwing angle is provided. The cleaning system includes a shoe for holding a sieve of the cleaning system, a mounting surface disposed on the shoe, and a rocker arm either movably or removably connected to the mounting surface. The rocker arm is configured to be mounted to the mounting surface at at least two different locations on the mounting surface. Each location resulting in a different throwing angle of the shoe of the cleaning system.

Abstract: A combine harvester is provided with a threshing system, a preparation arrangement and cleaning arrangement. The preparation arrangement comprises multiple preparation stages, each of said stages being configured to transport said mixture over a given distance between a front edge and a rear edge of the stage, with an air gap being present between each pair of consecutive stages. The preparation arrangement further comprises a blower, separate from the main blower, said blower configured to direct air towards at least one of said air gaps, to thereby blow at least a portion of said mixture towards the rear of the combine harvester. The preparation arrangement comprises a plate provided with fins mounted transversally with respect to the longitudinal direction of the harvester, each fin representing one of said preparation stages, the plate further comprising one or more openings between at least one pair of consecutive fins.

Abstract: A combine harvester having a cleaning system for separating seeds from by-products, that includes a transmission having an annular member, that extends around a circular element of an eccentric device and is pivotable around said circular element, a second arm having a first end fixedly connected to the annular member, and a second end connected with a reciprocatable cleaner device of a second cleaner assembly, a first arm having a first end fixedly connected to the annular member, a first cleaner drive linkage has a first end pivotably connected to the second end of the first arm and a second end connected to a reciprocatable cleaner device of a first cleaner assembly, wherein the reciprocatable cleaner device of the second cleaner assembly and the reciprocatable cleaner device of the first cleaner assembly are reciprocatingly drivable by the cleaning system drive assembly in generally opposite directions.

Abstract: A method and system for use with the combine to modify tailings conveyed to a cleaning system grain bed. Methods and systems are provided that utilize one or more sensors to detect uneven distribution of crop material in the grain bed, which provides information for a controller to determine whether adjustments to a tailings distribution system is needed to encourage even distribution of crop material in the grain bed. Elements in the tailings distribution system can be adjusted to alter direction of tailings conveyed to the grain bed to encourage even distribution of crop material on the grain bed. The system may also inform an operator of suggested manual adjustments to mitigate the non-uniformity.

Abstract: A method for controlling distribution of crop material to a cleaning sieve of an agricultural combine, for reducing grain loss, including while the combine is tilted sidewardly relative to horizontal, involving controlling the angular orientation of a distributor disposed between a threshing system of the combine and the sieve, for distributing a mat of the crop material onto the sieve evenly across an extent thereof. The angular orientation of the distributor can be set in advance of tilting of the combine, to adjust for a variety of conditions, including uneven outputting of the crop material from the threshing system, and the set orientation can be automatically maintained or actively adjusted to control a desired operating parameter such as grain loss, even as the combine is variously tilted and the angular orientation of the sieve relative to the combine is independently adjusted to maintain the sieve horizontal.
