Abstract

An arrangement for controlling the operation of a draper belt header of a combine harvester includes a central belt conveyor of the draper belt header having a drive for operably driving the conveyor and two outer belt conveyors attached to a feeder house of the combine harvester. The feeder house has a controllable height which may be controllably adjusted by an actuator. The arrangement further includes a control unit operable to stop the drive of the central belt conveyor or move it into a reversing mode if the feeder house is being raised by the actuator.

First claim

The invention claimed is:

1. An arrangement for controlling the operation of a draper belt header of a combine harvester, comprising:
a central belt conveyor of the draper belt header including a drive for operably driving the central belt conveyor;
two outer belt conveyors attached to a feeder house of the combine harvester, the feeder house comprising an adjustable height;
an actuator for controllably adjusting the height of the feeder house; and
a control unit operable to stop the drive of the central belt conveyor or move it into a reversing mode if the feeder house is being raised by the actuator.

2. The arrangement of claim 1 , wherein the actuator is operable to raise the feeder house out of a working position into a headland position.

3. The arrangement of claim 2 , wherein the control unit is operable to stop the drive of the central belt conveyor or move it into the reversing mode if the feeder house is raised into the headland position.

4. The arrangement of claim 1 , wherein the control unit operably actuates the drive based on an adjustment command given manually to the actuator.

5. The arrangement of claim 1 , wherein the control unit operably actuates the drive based on a position of the feeder house detected by a sensor.

6. The arrangement of claim 1 , wherein the control unit operably actuates the drive based on an output of a headland management system.

7. The arrangement of claim 1 , wherein:
the outer belt conveyors each include a drive for moving in a direction towards the central belt conveyor in a harvesting mode; and
the drive of the central belt conveyor operably moves the central belt conveyor in a direction toward the feeder house in the harvesting mode.

8. The arrangement of claim 7 , wherein, after a first time delay, harvested crop located on the outer belt conveyors is discharged into the feeder house prompted by a raising of the feeder house and the control unit is operable to stop or reverse the drive of the central belt conveyor.

9. The arrangement of claim 8 , wherein, after a second time delay, harvested crop which has accumulated below the central belt conveyor is discharged and the control unit instructs the drive of the central belt conveyor to terminate the reversing operation of the central belt conveyor.

10. The arrangement of claim 7 , wherein the feeder house is connected to another drive which is operable in a conveying mode after a raising of the feeder house for at least a time period in which harvested crop is conveyed by the outer belt conveyors into the combine harvester.

11. The arrangement of claim 7 , wherein:
the drives of the outer belt conveyors are connected to the control unit; and
the control unit is operable to shut down the drives of the outer belt conveyors after a raising of the feeder house for a time period which allows the harvested crops located on the outer belt conveyors to be discharged onto the central belt conveyor.

12. The arrangement of claim 1 , wherein the control unit is operable to control the drive of the central belt conveyor to move into a harvesting mode in the event of a lowering of the feeder house.

13. A combine harvester, comprising:
a feeder house mounted to a chassis;
a draper belt header;
a central belt conveyor including a drive for operably driving the central belt conveyor;
two outer belt conveyors attached to the feeder house of the combine harvester, the feeder house comprising an adjustable height;
an actuator for controllably adjusting the height of the feeder house; and
a control unit operable to stop the drive of the central belt conveyor or move it into a reversing mode if the feeder house is being raised by the actuator.

14. The combine harvester of claim 13 , wherein the actuator is operable to raise the feeder house out of a working position into a headland position, or the control unit is operable to stop the drive of the central belt conveyor or move it into the reversing mode if the feeder house is raised into the headland position.

15. The combine harvester of claim 13 , wherein the control unit operably actuates the drive based on an adjustment command given manually to the actuator, a position of the feeder house detected by a sensor, or an output of a headland management system.

16. The combine harvester of claim 13 , wherein:
the outer belt conveyors each include a drive for moving in a direction towards the central belt conveyor in a harvesting mode; and
the drive of the central belt conveyor operably moves the central belt conveyor in a direction toward the feeder house in the harvesting mode.

17. The combine harvester of claim 16 , wherein:
after a first time delay, harvested crop located on the outer belt conveyors is discharged into the feeder house prompted by a raising of the feeder house and the control unit is operable to stop or reverse the drive of the central belt conveyor; or
after a second time delay, harvested crop which has accumulated below the central belt conveyor is discharged and the control unit instructs the drive of the central belt conveyor to terminate the reversing operation of the central belt conveyor.

18. The combine harvester of claim 16 , wherein the feeder house is connected to another drive which is operable in a conveying mode after a raising of the feeder house for at least a time period in which harvested crop is conveyed by the outer belt conveyors into the combine harvester.

19. The combine harvester of claim 16 , wherein:
the drives of the outer belt conveyors are connected to the control unit; and
the control unit is operable to shut down the drives of the outer belt conveyors after a raising of the feeder house for a time period which allows the harvested crops located on the outer belt conveyors to be discharged onto the central belt conveyor.

20. A control system for controlling the operation of a draper belt header of a combine harvester, comprising:
a central belt conveyor of the draper belt header including a drive for operably driving the central belt conveyor;
a pair of belt conveyors disposed on each side of the central belt conveyor, the pair of belt conveyers attached to a feeder house of the combine harvester, wherein the feeder house comprises an adjustable height;
an actuator for controllably adjusting the height of the feeder house; and
a control unit operable to stop the drive of the central belt conveyor or move it into a reversing mode if the feeder house is being raised by the actuator;
wherein, the belt conveyors each include a drive for moving in a direction towards the central belt conveyor in a harvesting mode;
wherein, the drive of the central belt conveyor operably moves the central belt conveyor in a direction toward the feeder house in the harvesting mode.
