Abstract: An agricultural vehicle includes a chassis; a threshing and separating assembly carried by the chassis; and a cleaning system carried by the chassis and configured to receive crop material that has passed through the threshing and separating assembly. The cleaning system includes a pan configured to receive crop material from the threshing and separating assembly on a pan surface and to shake in a fore-to-aft direction; at least one sieve located below the pan and configured to shake in fore-to-aft and lateral directions, the sieve including a sieve surface configured to receive crop material from the pan; and at least one divider associated with and extending at least 3 centimeters above at least one of the pan surface and the sieve surface.

Abstract: A combine harvester including at least one straw walker extending in a longitudinal direction of the harvester and supported by a front and rear shaft. The shafts are rotatable about respective rotation axes, and each shaft provided with one or more eccentric portions. The straw walker is rotatably mounted on an eccentric portion of the respective front and rear shafts, so that the simultaneous rotation of the shafts actuates a reciprocating motion of the straw walker. The combine further comprises a pivot frame and one or more actuators, configured to adjust the angular position of the frame by pivoting the frame about a pivot axis oriented transversally to the longitudinal direction. The front and rear shafts are configured to rotate with respect to the pivot frame, so that the straw walker's angular position is adjustable while the straw walker executes the reciprocating motion.

Abstract: A cleaning shoe for an agricultural machine includes a chaffer supported for movement relative to a chassis, a sieve positioned below the chaffer and supported for movement relative to the chassis. The cleaning shoe also includes a first link, a second link, and a drive shaft. The first link includes a first end and a second end coupled to the chaffer. The second link includes a first end and a second end coupled to the sieve. The drive shaft rotates about a shaft axis and includes a first cam and a second cam. The first cam is coupled to the first end of the first link, and the second cam is coupled to the first end of the second link. Rotation of the drive shaft drives the first link to reciprocate the chaffer and drives the second link to reciprocate the sieve. The second cam is angularly offset relative to the first cam by a phase angle less than 180 degrees about the shaft axis.

Abstract: An agricultural harvester includes a chassis; at least one ground engaging traction member connected to the chassis; a cleaning system held by the chassis and configured to clean crop material; and an elevator supplied with the crop material cleaned by the cleaning system. The elevator includes a housing having a crop material inlet that receives the crop material, a boot portion that forms a bottom of the housing, an air inlet and an air outlet; a plurality of paddles configured to convey the crop material through the housing and away from the boot portion in a generally vertical direction; and a blower configured to produce a pressurized air stream through the air inlet that expels loose crop material into the air outlet as the crop material is conveyed away from the boot portion.

Abstract: A purifier is provided that is capable of uniformly sucking powder in a width direction of the sieve layers even when the purifier is configured to be provided with an air distribution chamber formed as being tapered upward and to have a horizontal cyclone provided above the air distribution chamber. The air distribution chamber is configured of paired inclined surfaces formed as being tapered upward, has a suction passage formed as a horizontal cyclone placed above the air distribution chamber. Also, a plurality of barrier walls are provided in the air distribution chamber in a direction perpendicular to a longitudinal direction of sieve layers, the air distribution chamber is sectioned by the barrier walls into a plurality of chambers, and rectifying plates are further provided to the air distribution chamber at a narrow position between the paired inclined surfaces to prevent non-uniformity of suction of powder on the sieve layers.

Abstract: A sieve for a thresher, especially a combine-harvester, for the separation of grain-like field fruits from stalk-like and chaff-like components has channels (2, 2a, 2b) extending parallel to a longitudinal axis (1). The channels (2, 2a, 2b) are open to a first side A, from which they are loaded. The channels (2, 2a, 2b) are delimited by a bottom 3 and laterally following flanks (4, 5) which include openings (9). Air guide following channels (10, 11) are open to a second side B, which face away from the first side A. The two air guide channels (10, 11) are arranged in a direction transverse to the longitudinal axis (1) and are separated by a continuous separation wall (13). The separation wall (13) extends between two neighbouring channels (2, 2a) which extend parallel to the longitudinal axis (1). In these separated air guide channels (10, 11), respectively, the openings (9) of only one of the two channels (2, 2a) separated by the air guide channels (10, 11) are open.

Abstract: A grain harvesting combine is provided with an improved sieve plate for more efficient cleaning of the grain. The sieve plate is mounted on the combine adjacent the rearward end thereof and is substantially rectangular in shape. The sieve plate has forward and rearward edges and opposite side edges, the forward edge and side edges being substantially coplanar. The sieve plate also has a forward portion which slopes downwardly from the forward edge and terminates in a substantially flat portion extending rearwardly to the rearward edge. Inclined opposite side portions are also provided which slope downwardly from each side edge to the flat portion of the sieve. The degree of incline of the forward portion and side portions is approximately 5.degree. from the flat portion. The inclined side portions minimized grain loss when the combine is operating on sloping terrain.
