Draper belt assembly for an agricultural harvester
A draper belt assembly for an agricultural harvester that includes a first roller, a second roller, and a draper belt surrounding the first and second rollers. The draper belt includes a front end, a rear end opposite the front end, and an upper surface extending from the front end to the rear end having a width substantially parallel to a longitudinal axis of one of the first and second rollers. The draper belt further includes a plurality of spaced apart lugs each extending in the widthwise direction having an anterior end distal to the rear end and a posterior end proximal to the rear end, wherein the anterior end is spaced from the front end of the draper belt at least about 15 mm.
1. A header for an agricultural harvester comprising:
a cutter bar extending in a widthwise direction of the header; and
a lateral draper belt assembly that includes:
a first roller,
a second roller, and
a draper belt surrounding the first and second rollers, the draper belt including:
a front end proximate the cutter bar,
a rear end opposite the front end and distal to the cutter bar, and
an upper surface extending from the front end to the rear end having a width substantially parallel to a longitudinal axis of one of the first and second rollers, and
a plurality of spaced apart lugs each extending in a widthwise direction having an anterior end distal to the rear end and spaced from the front end a first distance, and a posterior end proximal to the rear end and spaced from the rear end a second distance less than the first distance.
2. The header of claim 1 , wherein the anterior end is spaced from the front end of the draper belt about 20-30 mm.
3. The header of claim 1 , wherein the draper belt includes a planar upper surface extending from the front end to about 15-30 mm from the front end.
4. The header of claim 1 , wherein an entirety of a width of the front end of the draper belt includes a planar upper surface extending from the front end to about 15-30 mm from the front end.
5. The header of claim 1 , wherein each of the plurality of spaced apart lugs extends a length in the widthwise direction of about 900-1,000 mm.
6. The header of claim 1 , wherein the first distance is at least 15 mm.
7. The header of claim 1 , wherein the first distance is about 15-20 min.
8. The header of claim 1 , wherein the first distance is about 20-25 mm and the second distance is about 15-20 mm.
9. The header of claim 1 , wherein the first distance is at least 25 mm.
10. A header for an agricultural harvester comprising:
a cutter bar extending a width of the header;
a first draper belt adjacent the cutter bar, the first draper belt having a width extending perpendicular to a traveling direction of the draper belt, the first draper belt including:
a front end, a rear end opposite the front end, and an upper surface extending from the front end to the rear end, and
a plurality of lugs each extending in the widthwise direction of the first draper belt having an anterior end distal to the rear end and a posterior end proximal to the rear end,
wherein the anterior end is spaced from the front end a distance substantially equal to or greater than one-half a distance the guard extends rearwardly of the cutter bar; and
a guard adjacent to and extending rearwardly from the cutter bat above the front end of the first draper belt.
11. The header of claim 10 , wherein the anterior end is spaced from the front end a distance substantially equal to or greater than 75% a distance the guard extends rearwardly of the cutter bar.
12. The header of claim 10 , wherein the first draper belt includes a front planar upper surface extending from the front end to about 15-30 mm from the front end.
13. The header of claim 10 , wherein an entirety of a width of the front end of the first draper belt includes a front planar upper surface extending from the front end to about 15-30 mm from the front end.
14. The header of claim 10 , wherein each of the plurality of lugs extends a length in the widthwise direction of about 900-1,000 mm.
15. The header of claim 10 , wherein each of the guards extends about 20 to 30 mm from the cutter bar.
16. The header of claim 10 , further comprising:
a second draper belt adjacent the cutter bar; and
an infeed belt adjacent the first and second draper belts.
17. An agricultural harvester comprising the header of claim 10 .
18. The header of claim 10 , wherein the guard extends from the cutter bar about 20 to 30 mm.
19. The header of claim 10 , further comprises a back sheet adjacent the rear end of the draper belt.
20. The header of claim 10 , wherein the anterior end is spaced from the front end of the first draper belt a first distance, and the posterior end of each of the plurality of lugs is spaced from the rear end of the first draper belt a second distance less than the first distance.
