Abstract

A header for a combine harvester, the header including an auger for directing the movement of harvested grain toward a feederhouse of the combine harvester and an adjustable hood positioned above the auger and moveable between a lowered position, a raised position and an intermediate position between the lowered and raised positions. The adjustable hood includes a pivot mechanism and an actuator for moving the adjustable hood between the lowered, raised and intermediate position.

First claim

I claim:

1. A header of a combine harvester comprising:
an auger for directing the movement of harvested grain toward a feederhouse of the combine harvester; and
an adjustable hood positioned above the auger covering a width of the auger along its anterior posterior direction and moveable between a lowered position, a raised position and an intermediate position between the lowered and raised positions, the adjustable hood including:
a pivot mechanism, and
an actuator for moving the adjustable hood between the lowered, raised and intermediate positions.

2. The header of claim 1 , wherein the adjustable hood comprises a plurality of hood segments each independently and operatively connected to a respective actuator.

3. The header of claim 1 , wherein the actuator is in communication with a control unit for remotely controlling the adjustable hood between the lowered, raised and intermediate positions.

4. The header of claim 3 , wherein the control unit is configured to automatically position the adjustable hood based on a harvesting speed.

5. The header of claim 3 , further comprising a sensor in communication with the control unit, and wherein the control unit is configured to automatically position the adjustable hood based on feedback from the sensor.

6. The header of claim 5 , wherein the sensor is a moisture sensor and the control unit is configured to position the adjustable hood based on a sensed moisture reading.

7. The header of claim 1 , wherein the adjustable hood covers an entirety of the auger.

8. A header of a combine harvester comprising:
a frame for attaching to the combine harvester;
an auger extending widthwise of the frame; and
a hood assembly connected to the frame, the hood assembly including:
a hood extending above the auger covering a width of the auger along a direction transverse to a longitudinal axis of the auger and movably connected to the frame, and
a drive mechanism for moving the hood between a first position and a second position.

9. The header of claim 8 , wherein the hood assembly is in communication with a control unit for remotely controlling a position of the hood.

10. The header of claim 8 , wherein the drive mechanism is positioned about a lateral side of the hood assembly, or about a lateral side of the frame.

11. The header of claim 8 , wherein the drive mechanism is an actuator or a motor.

12. The header of claim 8 , wherein the hood comprises a plurality of hood segments each independently and operatively connected to a respective drive mechanism.

13. The header of claim 8 , wherein the hood assembly covers an entirety of the auger.

14. A combine harvester comprising:
a control unit; and
a header that includes:
a frame for attaching to the harvester,
an auger extending widthwise of the frame, and
a hood assembly connected to the frame, the hood assembly including:
a hood extending over and covering an entire longitudinal cross-sectional length of the auger, and
a drive mechanism for moving the hood between a first position and a second position, wherein the hood assembly is in communication with the control unit for remotely controlling a position of the hood.

15. The harvester of claim 14 , wherein the drive mechanism is positioned about a lateral side of the hood assembly, or about a lateral side of the frame.

16. The harvester of claim 14 , wherein the drive mechanism is an actuator or a motor.

17. The harvester of claim 14 , further comprising a sensor in communication with the control unit, and wherein the control unit is configured to automatically position the hood based on feedback from the sensor.

18. The harvester of claim 17 , wherein the sensor is a moisture sensor and the control unit is configured to position the hood based on a sensed moisture reading.

19. The harvester of claim 14 , wherein the hood comprises a plurality of hood segments each operatively connected to a respective drive mechanism.

20. The harvester of claim 19 , wherein each of the plurality of hood segments is independently positionable relative to each other.
