Abstract

A method and apparatus for harvesting cotton including a cotton accumulator configured to accumulate cotton removed from cotton plants. A feeder system of a cotton harvester is configured to move independently of the cotton accumulator and along a longitudinal direction. A round module builder system is configured to move along the longitudinal direction toward the feeder system, wherein the round module builder includes a contact member adapted to contact the feeder system to establish a working gap between the feeder system and the round module builder. A wrap floor is moved toward and into contact with the feeder system, which is spring biased to maintain a substantially consistent gap between the between the feeder system and round module builder. Cotton is directed toward the round module builder and a directing mechanism directs a wrap for wrapping the directed cotton into a round module.

First claim

The invention claimed is:

1. A cotton harvester including a cotton accumulator configured to accumulate cotton removed from cotton plants, the cotton harvester comprising:
a feeder system configured to move independently of the cotton accumulator and along a longitudinal direction, wherein the feeder system includes a cam follower; and
a wrap floor configured to move along the longitudinal direction toward the feeder system, wherein the wrap floor includes a contact member adapted to contact the feeder system to establish a working gap between the feeder system and the wrap floor, and wherein the wrap floor includes a cam,
wherein movement of the wrap floor toward the feeder system moves the cam into contact with the cam follower to determine a dimension of an adjustable gap disposed between the feeder system and the wrap floor.

2. The cotton harvester of claim 1 wherein the adjustable gap is defined by a belt of the feeder system and a gate roller of the wrap floor, wherein the belt of the feeder system is configured to move the accumulated cotton toward the wrap floor, and wherein the wrap floor is configured to direct a wrap toward the accumulated cotton moved by the feeder system.

3. The cotton harvester of claim 1 wherein the feeder system includes a feeder structure configured to move along a track fixed with respect to the accumulator.

4. The cotton harvester of claim 1 wherein the cam rotates about a rotational axis, and wherein contact of the cam with the cam follower rotates the cam about the rotational axis.

5. The cotton harvester of claim 1 wherein contact of the cam with the cam follower changes a location of the feeder system with respect to the longitudinal direction.

6. The cotton harvester of claim 1 further comprising wrap fingers operatively connected to the cam, wherein movement of the cam moves the wrap fingers toward a lower gate roller.

7. A work vehicle including a cotton accumulator configured to accumulate cotton removed from cotton plants to provide a round cotton module bound with a wrap, the work vehicle comprising:
a rolling feeder structure configured to move independently of the cotton accumulator along a longitudinal direction;
a wrap floor configured to move toward and away from the rolling feeder structure, wherein the wrap floor includes a contact member adapted to contact the rolling feeder structure to establish a working gap between the wrap floor and the rolling feeder structure; and
a track upon which the rolling feeder structure moves with respect to the accumulator, wherein the track is fixed to a chassis of the work vehicle and configured to maintain a lateral position of the rolling feeder structure with respect to the chassis.

8. The work vehicle of claim 7 wherein the contact member includes a cam member and the rolling feeder structure includes a cam follower, and wherein contact of the cam member with the cam follower determines a size of the working gap between the rolling feeder structure and the wrap floor.

9. The work vehicle of claim 7 wherein the rolling feeder structure further comprises an adjustable bias structure configured to resist a force applied to the rolling feeder structure by the wrap floor in response to the contact member contacting the rolling feeder structure.

10. The work vehicle of claim 9 wherein the contact member includes a cam member and the rolling feeder structure includes a cam follower, and wherein contact of the cam member with the cam follower determines a size of the working gap between the rolling feeder structure and the wrap floor.

11. The work vehicle of claim 7 , wherein the rolling feeder structure includes is movable on the track between a first position to move cotton toward the wrap floor and a second position to define an opening to provide access to the work vehicle for repair, maintenance, or replacement.

12. A work vehicle including a cotton accumulator, the work vehicle comprising:
a feeder system configured to move independently of the cotton accumulator that includes a cam follower;
a wrap floor configured for movement toward the feeder system that includes a cam; and
a track upon which the feeder system moves with respect to the cotton accumulator that is fixed to a chassis of the work vehicle and configured to maintain a lateral position of the feeder structure with respect to the chassis,
wherein movement of the wrap floor toward the feeder system moves the cam into contact with the cam follower to adjust a dimension of a gap disposed between the feeder system and the wrap floor.

13. The work vehicle of claim 12 , wherein the gap is defined by a belt of the feeder system and a gate roller of the wrap floor, wherein the belt of the feeder system is configured to move accumulated cotton toward the wrap floor, and wherein the wrap floor is configured to direct a wrap toward the accumulated cotton moved by the feeder system.

14. The work vehicle of claim 12 , wherein the cam rotates about a rotational axis in response to contact between the cam and the cam follower.

15. The work vehicle of claim 12 , wherein contact between the cam and the cam follower changes a location of the feeder system in a longitudinal direction.

16. The work vehicle of claim 12 , further comprising wrap fingers operatively connected to the cam, wherein movement of the cam causes movement of the wrap fingers toward a lower gate roller.

17. The work vehicle of claim 12 , wherein the feeder system is movable on the track between a first position to move cotton toward the wrap floor and a second position to define an opening to provide access to the work vehicle for repair, maintenance, or replacement.

18. The work vehicle of claim 12 , wherein the feeder system includes an adjustable bias structure configured to resist a force applied to the feeder system by the wrap floor in response to contact between the cam and the cam follower.

19. The work vehicle of claim 18 , wherein the bias structure includes a spring that biases the feeder system toward the wrap floor.

20. The work vehicle of claim 19 , wherein the bias structure includes a travel limiter that limits longitudinal travel of the feeder system relative to the wrap floor.
