Abstract

A wrap feed arrangement is disclosed for an agricultural harvester having a module-forming chamber. The arrangement includes a conveyor arrangement, which delivers crop to the module-forming chamber, and a module-forming arrangement which, at least in part, builds the module. The conveyor arrangement has a first roll and a first endless member disposed about the first roll for rotation. The module-forming arrangement has a second roll and a second endless member disposed about the second roll for rotation. At least one of the first and second rolls is movable from a first position in which the first and second endless members are disengaged to a second position in which the first and second endless members are engaged.

First claim

What is claimed is:

1. A wrap feed arrangement for an agricultural harvester having a module-forming chamber, the arrangement comprising:
a conveyor arrangement including a first roll and a first endless member disposed about the first roll and configured to rotate to deliver crop material to the module-forming chamber of the agricultural harvester;
a module-forming arrangement associated with the module-forming chamber of the agricultural harvester, the module-forming arrangement having a second roll and a second endless member disposed about the second roll and configured to rotate to form a module within the module-forming chamber; and
a slide mechanism having a carriage and an actuator, the carriage having a guide having a first mounting bracket that couples to the actuator and having a second mounting bracket having a wall with a track opening configured to accommodate an axle mounting a sprocket;
wherein at least one of the first and second rolls is movable by the slide mechanism from a first position in which the first and second endless members are disengaged to a second position in which the first and second endless members are engaged.

2. The arrangement of claim 1 , wherein the first and second rolls counter-rotate so that the first and second endless members engage and travel in a common direction at a nip location at an inlet to the module-forming chamber of the agricultural harvester.

3. The arrangement of claim 1 , wherein the first and second endless members are belts.

4. The arrangement of claim 3 , wherein each of the first and second endless members includes a plurality of belts.

5. The arrangement of claim 1 , wherein the first roll is mounted for translation between the first position and the second position, and wherein the first roll translates in a direction orthogonal to an axis of rotation of the first roll.

6. The arrangement of claim 5 , wherein the slide mechanism is coupled to the first roll for translation of the first roll from the first position to the second position.

7. The arrangement of claim 6 ,
wherein actuation of the actuator translates the carriage in a direction of travel extending between the axes of rotation of the first and second rolls.

8. The arrangement of claim 7 , wherein the actuator is a piston-cylinder arrangement.

9. The arrangement of claim 7 , wherein the second mounting bracket couples to the first roll.

10. The arrangement of claim 9 , wherein the sprocket is a fixed sprocket on which the carriage slides.

11. The arrangement of claim 10 , wherein the first roll is coupled for rotation with a one-way sprocket, and wherein in the first position, the one-way sprocket engages the fixed sprocket to prevent rotation of the first roll in at least one rotational direction, and wherein in the second position, the one-way sprocket is disengaged from the fixed sprocket to enable rotation of the first roll in either rotational direction.

12. A wrap feed arrangement for an agricultural harvester having a module-forming chamber, the arrangement comprising:
a conveyor arrangement including a first roll and a first endless member disposed about the first roll and configured to rotate to deliver crop material to the module-forming chamber of the agricultural harvester;
a module-forming arrangement associated with the module-forming chamber of the agricultural harvester, the module-forming arrangement having a second roll and a second endless member disposed about the second roll and configured to rotate to form a module within the module-forming chamber; and
a slide mechanism coupled to at least one of the first and second rolls for translation of at least one of the first and second rolls from a first position to a second position, the slide mechanism having a carriage and an actuator, the carriage having a guide having a first mounting bracket that couples to the actuator and having a second mounting bracket having a wall with a track opening configured to accommodate an axle mounting a sprocket;
wherein in first position the first and second endless members are disengaged and in the second position the first and second endless members are engaged.

13. An agricultural harvesting machine, comprising:
a module-forming chamber;
a conveyor arrangement including a first roll and a first endless member disposed about the first roll and configured to rotate to deliver crop material to the module-forming chamber of the agricultural harvester; and
a module-forming arrangement associated with the module-forming chamber having a second roll and a second endless member disposed about the second roll and configured to rotate to form a module within the module-forming chamber;
a slide mechanism having a carriage and an actuator, the carriage having a guide having a first mounting bracket that couples to the actuator and having a second mounting bracket having a wall with a track opening configured to accommodate an axle mounting a sprocket;
wherein at least one of the first and second rolls is movable by the slide mechanism from a first position in which the first and second endless members are disengaged to a second position in which the first and second endless members are engaged.

14. The machine of claim 13 , wherein the first and second rolls counter-rotate so that the first and second endless members engage and travel in a common direction at a nip location at an inlet to the module-forming chamber of the agricultural harvester.

15. The machine of claim 13 , wherein the first and second endless members are belts, and wherein each of the first and second endless members includes a plurality of belts.

16. The machine of claim 13 , wherein the first roll is mounted for translation between the first position and the second position, and wherein the first roll translates in a direction orthogonal to an axis of rotation of the first roll.

17. The machine of claim 13 ,
wherein actuation of the actuator translates the carriage in a direction of travel extending between axes of rotation of the first and second rolls.

18. The machine of claim 17 , wherein the second mounting bracket couples to the first roll.

19. The machine of claim 18 , wherein the sprocket is a fixed sprocket on which the carriage slides.

20. The machine of claim 19 , wherein the first roll is coupled for rotation with a one-way sprocket, and wherein in the first position, the one-way sprocket engages the fixed sprocket to prevent rotation of the first roll in at least one rotational direction, and wherein in the second position, the one-way sprocket is disengaged from the fixed sprocket to enable rotation of the first roll in either rotational direction.
