Rotational rotor discharge deflector
An agricultural vehicle including a rotor configured for threshing a crop material and a housing located at a distance radially away from the rotor and circumferentially encasing at least a portion of the rotor. The agricultural vehicle also includes a discharge chopper positioned downstream of the rotor in a direction of crop material flow, and a discharge deflector moveably connected to the housing, circumferentially disposed around at least a portion of the rotor, and located at a radial distance away from the rotor. The discharge deflector has a distal end that defines a discharge opening for allowing the crop material to pass from the rotor to the discharge chopper such that as the discharge deflector is moved a circumferential position of the discharge opening is correspondingly moved without changing the radial distance between the discharge deflector and the rotor.
1. An agricultural vehicle, comprising:
a rotor configured for threshing a crop material;
a housing located at a distance radially away from the rotor and circumferentially encasing at least a portion of the rotor, said housing having an inner surface facing the rotor;

2. The agricultural vehicle of claim 1 , wherein the deflector track is circumferentially disposed around at least a portion of the rotor.
3. The agricultural vehicle of claim 1 , further including a drive configured for rotating the discharge deflector relative to the rotor in a circumferential direction.
4. The agricultural vehicle of claim 3 , wherein said drive is one of a hydraulic drive and an electric drive.
5. The agricultural vehicle of claim 3 , wherein said drive includes at least one gear, and said discharge deflector includes a gear track such that said at least one gear correspondingly mates with said gear track in order to move the discharge deflector.
6. The agricultural vehicle of claim 1 , wherein said discharge deflector extends around a majority of an upper perimeter of the rotor.
7. The agricultural vehicle of claim 1 , wherein the discharge deflector is a monolithic, arced metal panel extending around a majority of an upper perimeter of the rotor.
8. The agricultural vehicle of claim 1 , wherein the discharge deflector comprises multiple sections, each of said multiple sections being configured to be moved independently via a separate drive.
9. The agricultural vehicle of claim 1 , wherein the deflector track extends fully around a travel path of the discharge deflector.
10. A residue system for an agricultural vehicle having a rotor and a housing surrounding the rotor, comprising:
a discharge chopper configured for processing a crop material downstream of the rotor in a direction of crop material flow;
a discharge deflector configured for being moveably connected to an inner surface of the housing that faces the rotor, circumferentially disposed around at least a portion of the rotor, and located at a radial distance away from the rotor, said discharge deflector having a distal end that defines a discharge opening for allowing the crop material to pass from the rotor to the discharge chopper such that as said discharge deflector is moved a circumferential position of the discharge opening is correspondingly moved without changing said radial distance between the discharge deflector and the rotor; and
a deflector track fixedly connected to the inner surface of the housing facing the rotor, said deflector track slideably mounting the discharge deflector such that at least a portion of the discharge deflector is slideably received within the deflector track.
11. The residue system of claim 10 , wherein the deflector track is circumferentially disposed around at least a portion of the rotor.
12. The residue system of claim 10 , further including a drive configured for rotating the discharge deflector relative to the rotor in a circumferential direction.
13. The residue system of claim 12 , wherein said drive is one of a hydraulic drive and an electric drive.
14. The residue system of claim 12 , wherein said drive includes at least one gear, and said discharge deflector includes a gear track such that said at least one gear correspondingly mates with said gear track in order to move the discharge deflector.
15. The residue system of claim 10 , wherein said discharge deflector is configured for extending around a majority of an upper perimeter of the rotor.
16. A method of operating an agricultural vehicle having a rotor and a housing surrounding the rotor, comprising the steps of:
providing a residue system including a discharge chopper configured for processing a crop material downstream of the rotor in a direction of crop material flows;
fixedly connecting a deflector track to an inner surface of the housing that faces the rotor;
slideably mounting a discharge deflector to the deflector track such that at least a portion of the discharge deflector is slideably received within the deflector track, circumferentially disposed around at least a portion of the rotor, and located at a radial distance away from the rotor, said discharge deflector having a distal end that defines a discharge opening for allowing the crop material to pass from the rotor to the discharge chopper;
directing a crop material flow by the discharge deflector toward the discharge chopper;
changing a circumferential position of the discharge opening by moving said discharge deflector; and
maintaining said radial distance between the discharge deflector and the rotor as said circumferential position of the discharge opening is changed.
17. The method of claim 16 , wherein the deflector track is circumferentially disposed around at least a portion of the rotor.
18. The method of claim 16 , further including a drive configured for rotating the discharge deflector relative to the rotor in a circumferential direction.
19. The method of claim 18 , wherein said drive includes at least one gear, and said discharge deflector includes a gear track such that said at least one gear correspondingly mates with said gear track in order to move the discharge deflector.
20. The method of claim 16 , wherein said discharge deflector is configured for extending around a majority of an upper perimeter of the rotor.
