The present invention comprises multiple embodiments of an automated, dynamic cover plate system, which may be quickly attached, detached and adjusted to the exterior of a concave grate of a combine harvester in order to adjust the flow characteristics of the concave or separator grate assemblies. The automated, dynamic cover plate system improves the threshing capability of the rasp bar threshing cylinder while simultaneously capturing additional threshed grain. The automated, dynamic cover plate system of the present invention is designed to be controlled, either manually or automatically, by the operator of the combine harvester or by a computerized or automated intelligence system.

A graphical user interface (60) for a combine harvester (10) includes, in a first portion (62) of the user interface, a graphical representation (66, 70) of an amount of material passing through a threshing system (22) at multiple positions along a longitudinal direction of the combine harvester, and a graphical representation (68, 72) of an amount of material passing through a cleaning system (42) at multiple positions along the longitudinal direction of the combine harvester. The user interface further includes, in a second portion (64) of the user interface, a graphical representation (74, 78) of an amount of material passing through the threshing system (22) at a plurality of locations along a lateral axis of the combine harvester, and a graphical representation (76, 80) of an amount of material passing through the cleaning system (42) at a plurality of locations along the lateral axis of the combine harvester.

The invention comprises a method for increasing the harvesting effectiveness of a combine harvester using a removable cover plate assembly, which may be quickly attached, detached and adjusted to the exterior of a concave grate of a combine harvester in order to adjust the flow characteristics of the concave or separator grate assemblies. The method for using the cover plate assembly increases the threshing capability of the rasp bar threshing cylinder while simultaneously capturing additional threshed grain. Moreover, the cover plate assembly of the present invention enables a single set of concave grate assemblies to better harvest a wider variety of crop types.

A method and device for harvesting grain crops is provided. A threshing method includes separating grain from harvested material, which is fed to a threshing phase after a gathering process taking place against a direction of working travel. During threshing, the harvested material is processed as the respective grain crops and admixtures in the form of straw and chaff such that essential, dischargeable admixtures are separated from the grain crops, and these, in the form of a mixture with chaff or similar fine particles, are fed as a grain/chaff stream to a final cleaning. The grains free of these residual admixtures are subsequently collected as grain crops. During at least one feed phase preceding the final cleaning, a transport movement is imparted to the at least one grain/chaff stream with the transport movement having a component in a vertical direction and a component in the direction of working travel.

An arrangement for switching over a combine harvester between swath deposit operation and wide distribution operation comprises a front element and a rear element which follows downstream. The rear element may be attached in an articulated fashion, in an inherently rigid fashion, at its upstream end about a first pivoting axis and may be moved between a swath deposit position and a wide distribution position by an adjustment drive. The front element may be attached in an articulated fashion at its upstream end about a second pivoting axis, may be inherently rigid and may also be coupled to the adjustment drive.

A work machine receives a thematic map that maps values of a variable to different geographic locations at a worksite. Control zones are dynamically identified on the thematic map and actuator settings are dynamically identified for each control zone. A position of the work machine is sensed, and actuators on the work machine are controlled based upon the control zones that the work machine is in, or is entering, and based upon the settings corresponding to the control zone. These control zones and settings are dynamically adjusted based on in situ (field) data collected by sensors on the work machine.

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.

A threshing and separating system for an agricultural harvester includes a rotor configured to rotate about a rotor axis, a rotor cage at least partially enclosing the rotor and including a tailings return inlet formed therein and configured to couple to a tailings return elevator and an insert opening formed therein that is at least partially circumferentially aligned with the tailings return inlet relative to the rotor axis, at least one concave coupled to the rotor cage and defining a plurality of concave perforations, and a threshing insert removably coupled to the rotor cage and including at least one mounting opening. The threshing insert at least partially covers the insert opening and is positioned such that material from the tailings return inlet travels past the threshing insert before reaching the concave.
