Abstract: Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The seeds are carried axially of the rotor by a controlled airstream so that they move to an axial discharge location where a discharge fan is mounted. The angle of the discharge around the rotor axis can be changed to direct the seeds to the side of the combine away from a straw chopper, towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.

Abstract: An agricultural combine has a cleaning shoe including an upper sieve or chaffer over a lower sieve. The lower sieve is over a clean gain chute. A return chute open to a return opening is under the clean grain chute. The clean grain chute receives clean grain from the chaffer and the lower sieve. The return chute receives unclean grain and tailings from the cleaning shoe through the return opening. The chaffer's rear extremity extends beyond the lower sieve's rear extremity configured with a sieve chute. The sieve chute is spaced under the chaffer's rear extremity and extends rearward and angularly upward above the return opening toward the chaffer's rear extremity from the lower sieve's rear extremity, allowing the sieve chute to intercept grain from the chaffer and divert it forward to the lower sieve and away from the return opening.

Abstract: A combine harvester includes a feederhouse configured to convey a crop material from a harvesting header, a threshing system configured to receive the crop material from the feederhouse and separate straw therefrom, and a cleaning system below the threshing system and configured to separate grain from chaff of the crop material. The cleaning system includes a reversible return system configured to receive the crop material from the threshing system, a grain pan below the return system, at least one oscillating grate configured to receive the crop material from the grain pan, and a blower configured to direct air rearward and upward through the oscillating grate. The return system delivers the crop material to a forward end of the grain pan in a first operating mode, and to a rearward end of the grain pan in a second operating mode. Related methods are also disclosed.

Abstract: A combine crop trash removal system for mounting to a combine corn harvester using hydraulically driven air blowers coupled to the combine header control system for reduction and/or removal of stalks, leaves, dirt and dust type material from accumulating on the combine feeder house and obscuring the operators view of the operating combine header during operation of the combine harvester for corn picking. The air blower may also be driven electrically or pneumatically. The operator of the combine harvester controls the crop trash removal system from the operator cab of the combine harvester.

Abstract: An agricultural grain cleaner includes an inlet chute having an inlet end and an outlet end positioned below the inlet end. A crop distribution member is positioned adjacent the outlet end of the inlet chute. The crop distribution member includes a distribution disc rotatable relative to the inlet chute about a vertical central axis to impart a horizontal trajectory, away from the central axis, to crop material supplied to the distribution disc from the inlet chute. A fan is operable to generate an air stream from below the crop distribution member, across the horizontal trajectory, to an air-chaff outlet. A grain collection chute has an inlet to receive grain that is cleaned of chaff by the air stream. A tailings collection chute is positioned adjacent to the grain collection chute on a radially inner side thereof.

Abstract: A method includes introducing at least one of a whole product or a milled product (e.g., corn) to an airflow (e.g., using a gravity hopper), directing the airflow into one or more accelerators, separating a first fraction of the at least one of the whole product or the milled product from a second fraction of the at least one of the whole product or the milled product in the one or more accelerators. For example, corn germ, starch, and bran components can be separated from one another.

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 crop residue spreader including at least one impeller, at least one radial housing, and at least one blower outlet opening. The at least one radial housing includes a crop residue outlet opening. The at least one impeller is configured to be rotatably driven around a rotation axis such that a crop residue flow is ejected through the crop residue outlet opening of the at least one radial housing, such that the crop residue flow is converted from an incoming crop residue flow into a wider outgoing crop residue flow. The at least one separate blower outlet opening is separate from the crop residue outlet opening of the at least one radial housing. The at least one blower outlet opening is configured to provide an outgoing airflow to accelerate the crop residue flow.

Abstract: A combine harvester comprising threshing apparatus, a grain pan and a cleaning unit is provided. The grain pan is arranged to collect a grain/chaff stream from the threshing apparatus and is driven in an oscillating manner to convey the collected grain/chaff stream rearwardly to a rear edge from where the grain/chaff stream falls under gravity into the cleaning unit. The cleaning unit comprises a fan unit for generating a first cleaning airstream which is directed under the grain pan and through the grain/chaff stream falling from said rear edge. The combine harvester further comprises means to generate a second cleaning airstream vented above the grain pan.
