Abstract

Official abstract text for this publication.

A threshing and separating system for an agricultural harvester includes: a rotor; a rotor cage at least partially enclosing the rotor, the rotor cage including a first flat wall, a second flat wall connected to and angled with respect to the first flat wall, and a curved wall connected to the second flat wall; and at least one vane connected to the first flat wall or the second flat wall.

First claim

Opening claim text (preview).

What is claimed is: 1. A threshing and separating system for an agricultural harvester, comprising: a rotor having a rotor axis; a rotor cage at least partially enclosing the rotor, the rotor cage including a first flat wall, a second flat wall connected to and angled with respect to the first flat wall, and a curved wall connected to the second flat wall; at least one vane connected to the first flat wall; and at least one vane connected to the second flat wall, wherein the at least one vane connected to the first flat wall and the at least one vane connected to the second flat wall are helically aligned relative to the rotor axis. 2. The threshing and separating system of claim 1 , wherein the rotor cage defines a diameter between a first wall end of the first flat wall and the curved wall. 3. The threshing and separating system of claim 2 , wherein the at least one vane connected to the first flat wall is an at least one fixed vane. 4. The threshing and separating system of claim 2 , wherein the at least one vane connected to the first flat wall is fixed, and wherein the at least one vane connected to the second flat wall is adjustable. 5. The threshing and separating system of claim 4 , wherein the curved wall defines a radius relative to the rotor axis which is adjacent to a second wall end of the second flat wall. 6. The threshing and separating system of claim 1 , wherein the rotor is configured to rotate in a rotational direction, wherein the second flat wall follows the first flat wall in the rotational direction, and wherein the curved wall follows the second flat wall in the rotational direction. 7. The threshing and separating system of claim 1 , wherein the rotor cage defines a length from a front of the rotor cage to a rear of the rotor cage, and wherein the first flat wall and the second flat wall extend from the front of the rotor cage to the rear of the rotor cage. 8. The threshing and separating system of claim 1 , wherein the curved wall defines an arc with an arc length of at least 90 degrees relative to the rotor axis. 9. An agricultural harvester, comprising: a threshing and separating system comprising: a rotor configured to rotate in a rotational direction about a rotor axis; a rotor cage at least partially enclosing the rotor, the rotor cage including a first flat wall, a second flat wall connected to an angled with respect to the first flat wall, and a curved wall connected to the second flat wall; a fixed vane affixed to the first flat wall; and an adjustable vane movably connected to the second flat wall and substantially aligned circumferentially with the fixed vane about the rotor axis, the adjustable vane following the fixed vane in the rotational direction; and a cleaning system. 10. The agricultural harvester of claim 9 , wherein the curved wall defines a radius relative to the rotor axis which is adjacent to a second wall end of the second flat wall. 11. The agricultural harvester of claim 9 , wherein the curved wall follows the second flat wall in the rotational direction. 12. The agricultural harvester of claim 9 , wherein the rotor cage defines a length from a front of the rotor cage to a rear of the rotor cage, and wherein the first flat wall and the second flat wall extend from the front of the rotor cage to the rear of the rotor cage. 13. The agricultural harvester of claim 9 , wherein the curved wall defines an arc with an arc length of at least 90 degrees relative to the rotor axis.
