  • Patent number: 6802771
    Abstract: An agricultural harvesting machine for removing and separating grain from harvested crop has a threshing zone and at least one separation zone for separating the grain. The axial separating rotor is at least partially encased by a separating housing having a plurality of sections. At least one of the sections is displaceable in the axial direction of the at least one axial separating rotor to increase the opening and ensure separation when a correspondingly large proportion of grain are in the outer region of the rotating crop stream and the proportion of admixtures is small.

  • Patent number: 6537148
    Abstract: An apparatus for separating grain, kernel or cereal from harvested crop includes a separating rotor operatively mounted in a rotor housing and having a rotor axis, and a separating grate which partly surrounds the separating rotor and forms a lower part of the rotor housing. The separating grate includes a plurality of frame portions, profiles operatively connected to the plurality of frame portions and extending parallel to the rotor axis, and webs having apertures therein and bent in a step-like shape. The webs are mounted between the profiles and the plurality of frame portions and transverse to the rotor axis forming a sieve area for separating the grain from the crop mat. The separating grate is utilized in a combine harvester, preferably a self-propelled combine harvester. The sieve area is used to sift, separate or loosen grain, kernel or cereal from the crop with reduced fragmentation and clogging.

  • Patent number: 6517431
    Abstract: A self-propelled combine harvester includes a transfer zone with side panels and a meshing and feed drum which functions on the tangential flow principle. The feed drum feeds the harvested crop to the separating rotors, which function on the axial flow principle and are rotatably mounted in rotor housings. Side panels are operatively mounted on the rotor housing in the frontal pickup region thereof Guide rails are directed upwardly at an acute angle and become increasingly elevated in the direction of conveyance, for imparting an upward, axially directed pulse to the harvested crop whereby the increasing elevation amplifies this pulse without thereby blocking the pickup zone in a frontal region. Dividing wedge for dividing the harvested crop into two paths, wherein the harvested crop glides over the dividing wedge towards the rotor housings and the long stemmed materials, such as stalks, are caught by the separating rotors and drawn into the corresponding rotor housing via the dividing wedge.

  • Publication number: 20010054279
    Abstract: The invention relates to a self-propelled combine harvester having a ground drive assembly, a frame, working implements for picking up, conveying, processing and expelling the harvested crop, drive devices for driving at least one meshing and feed drum, which functions on the tangential flow principle. The feed drum feeds the harvested crop to the separating rotors, which function on the axial flow principle and are rotatably mounted in rotor housings. Conveying implements are mounted on the separating rotors. A rotor core of the separation rotors has a substantially cylindrical basic shape on the outer contour where the conveying implements are mounted. The rotor core tapers from narrow to wide in a direction away from the feed drum. Side panels are operatively mounted on the rotor housing in the frontal pickup region thereof to improve the transfer of the harvested crop from the feed drum to the rotor housings.
