| 20140171164 | Concave for Rotary Combine - There is provided a concave for a rotary combine which includes a body having a plurality of curved frame sections connected in parallel side by side relation. Each of the curved frame section has having ends and sides. The body has an entry end and an exit end. Each of the curved frame sections has a face with an upstanding crop processing profile. For the curved frame sections at the entry end of the body the crop processing profile is a threshing profile having an orientation extending between the sides. For the curved frame sections at the exit end of the body the crop processing profile is a separation profile of sine wave vanes having an orientation extending toward the ends and having apertures positioned between the vanes to permit passage of grain. | 06-19-2014 |
| 20140308998 | Constant Pressure Concave Assembly in a Combine Harvester Processing System - A combine harvester has a crop processing rotor and a concave assembly having at least one concave extending at least partially beneath the rotor in a circumferential manner. The concave assembly is pivotable about pivot point to move the concave in a generally concentric manner toward and away from rotor. An operating mechanism pivots the concave assembly to adjust the operating clearance between the concave assembly and the rotor. The operating mechanism includes an actuator and a linkage assembly connecting the actuator to the concave assembly. The linkage assembly includes a hydraulic cylinder that applies a substantially constant force to the concave assembly to control the pressure put on the crop while the rotor is rotating. A hydraulic supply ports hydraulic fluid to the hydraulic cylinder. The combine harvester also has an accumulator located between the hydraulic supply and the hydraulic cylinder. | 10-16-2014 |

| 20140194170 | Threshing mechanism - A threshing mechanism is formed with a first threshing drum and a second threshing drum disposed one behind the other in a direction of crop flow. A first concave encloses the first threshing drum and the second threshing drum in sections in a circumferential direction. A second concave encloses the second threshing drum in sections in the circumferential direction. The concaves are displaceable in a radial direction of the threshing drums and are formed with at least one crop-processing device disposed at the first concave. The first concave and the second concave are swivellable about a common axis connecting the concaves. The enclosure of the second threshing drum by the first concave and the second concave is approximately identical. | 07-10-2014 |

| 20090215510 | Collecting trough construction easily accessible for cleaning - A collecting trough construction for facilitating the clean out of collecting troughs of clean grain and tailings collecting and conveying systems of agricultural combines, such collecting trough construction including a base pan sized and dimensioned to extend longitudinally between first and second cross-pieces of such a collecting and conveying system, one of which cross-pieces may be a clean grain auger trough or a tailings auger trough, and laterally generally between the sidesheets of a combine, with collecting troughs formed in the upper side thereof, which base pan has first and second ends and is positionable between the first and second cross-pieces with the first end of the auger trough base pan adjacent the first cross-piece and the second end of the auger trough base pan adjacent the second cross-piece to be readily complementarily engageable therewith and wholly or partially disengageable therefrom by a user to permit convenient access to the formed collecting troughs for cleaning thereof. Preferably, the base pan is, alternatively, partially detachable to permit access for cleaning by a user in an in-place clean-out position or wholly removable to permit the removal of such base pan to a remote location for cleaning by the user thereat. | 08-27-2009 |
| 20110151951 | Concave Adjustment Mechanism - A combine harvester where opposing concaves on either side of a rotor of a processing system substantially simultaneously travel symmetrical paths. The concaves of the processing system may be pivotally supported on a rockshaft where the axis of the rockshaft moves in a generally vertical manner so that the concaves then move generally radially toward or away from the rotor. | 06-23-2011 |
| 20120270612 | SUPPORT SYSTEM FOR SEPARATOR GRATES OF A HARVESTER - A support system for separator grates of a harvester includes a first member and a second member extending substantially parallel to an axis of rotation of a threshing rotor. The first member extends from a staging portion to a first support portion rearwardly positioned from the staging portion. The second member extends along a second support portion that corresponds to the first support portion. Separator grate segments may be selectably installed and removed from the first member and second member. | 10-25-2012 |

| 20110143827 | HELICAL BAR CONCAVE AND METHOD OF MANUFACTURING - A helical bar concave comprising 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. 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. | 06-16-2011 |
