Belt pickup for a draper header

1. A crop gathering device for use with a harvesting header comprising:

a frame carrying a structure movable about an endless path to deliver a crop to the header, the frame having opposed ends and connected to the header;

the frame comprising:

a first support member and a second support member, each support member extending between the opposed ends of the frame and the first and second support members are disposed longitudinally adjacent to each other;

a driven roller assembly extending between the opposed ends of the frame; and

an idler roller assembly extending between the opposed ends of the frame, wherein the first and second support members are disposed in between the driven roller assembly and the idler roller assembly, such that the first support member is longitudinally adjacent the driven roller assembly and the second support member is longitudinally adjacent the idler roller assembly; and

wherein the driven roller assembly and the idler roller assembly are configured and positioned to move the structure for delivering a crop to the header.

2. The device of claim 1 , wherein the structure is a belt.

3. The device of claim 2 , wherein the belt includes tines extending outwardly from the belt.

4. The device of claim 1 , wherein a distance between ends of the first support member and a second support member is selectively adjustable.

5. The device of claim 1 , wherein the first support member and the second support member are positioned substantially parallel to each other.

6. The device of claim 1 , wherein a guide positioned between ends of the first support member and the second support member is secured to the first support member and extends into the second support number.

7. The device of claim 1 , wherein the at least two axially aligned rollers of the driven roller assembly are interconnected during operation of the device.

8. The device of claim 1 , wherein at least one of the first support member and the second support member is of unitary construction.

9. The device of claim 1 , wherein the first support member and the second support member each include segments that are assembled together.

10. The device of claim 1 , wherein an insert member is positioned between facing ends of the support members which are assembled together.

11. The device of claim 1 , wherein at least one of the first support member and the second support member is a C-channel.

12. The device of claim 1 , wherein at least one of the first support member and the second support member is a tube.

13. The device of claim 1 , wherein fittings having axially aligned openings receive facing ends of the rollers of the roller assemblies.

14. The device of claim 1 , wherein the first and second support members have fittings at approximately midspan of each respective support member, the driven roller assembly having at least two axially aligned rollers extending between the opposed ends of the frame, wherein one end of each roller of the driven roller assembly is rotatably secured to the fitting of the first support member, and

the idler roller assembly having at least two axially aligned rollers extending between the opposed ends of the frame, wherein one end of each roller of the idler roller assembly is rotatably secured to the fitting of the second support member.

15. A crop gathering device for use with a harvesting header comprising:

a frame carrying a belt about an endless path to deliver a crop to the header, the frame having opposed ends and connected to the header;

the frame comprising:

a first support member and a second support member, each support member extending between the opposed ends of the frame and the first and second support members are disposed longitudinally adjacent to each other;

a driven roller assembly extending between the opposed ends of the frame; and

an idler roller assembly extending between the opposed ends of the frame, wherein the first and second support members are disposed in between the driven roller assembly and the idler roller assembly, such that the first support member is longitudinally adjacent the driven roller assembly and the second support member is longitudinally adjacent the idler roller assembly; and

wherein the driven roller assembly and the idler roller assembly are configured and positioned to move the structure for delivering a crop to the header;

wherein the driven roller assembly and the idler roller assembly are configured and positioned to maintain substantially equal forces along regions of contact with the belt.

16. The device of claim 15 , wherein a distance between ends of the first support member and a second support member is selectively adjustable.

17. The device of claim 15 , wherein the at least two axially aligned rollers of the driven roller assembly are interconnected during operation of the device.

18. The device of claim 15 , wherein at least one of the first support member and the second support member is of unitary construction.

19. The device of claim 15 , wherein an insert member is positioned between facing ends of the support members which are assembled together.

20. The device of claim 15 , wherein a guide is coupled to one support member and extends inside the another support member to provide tracking between the first and second support members.

21. The device of claim 20 , wherein the guide is coupled to the first and second support members at midspan thereto.
