Abstract

An agricultural harvester discharge guide includes a porous apparatus adapted for mounting to a discharge end of the agricultural harvester for guiding crop residue discharged from the agricultural harvester.

First claim

What is claimed is:

1. An agricultural harvester comprising an agricultural harvester discharge guide configured to guide crop residue entrained in a volume of air flowing therethrough, the crop residue entrained in the volume of air having an initial concentration, the agricultural harvester discharge guide comprising:
a housing having opposed, first and second sides having corresponding lower ends and a discharge surface spaced from the lower ends of the first and second sides of the housing by first and second air discharge ports, respectively, the first and second sides and the discharge surface defining a discharge opening configured to direct the crop residue in a discharge direction, opposite a direction of travel of the agricultural harvester;
a first porous apparatus extending between the lower end of the first side of the housing and the discharge surface and positioned in the first discharge port, the first porous apparatus adapted to allow a first portion of the air to pass therethrough in a first exhaust direction, substantially perpendicular to the direction of travel, while discouraging the crop residue from passing therethrough in the first exhaust direction; and
a second porous apparatus extending between the lower end of the second side of the housing and the discharge surface and positioned in the second discharge port, the second porous apparatus adapted to allow a second portion of the air to pass therethrough in a second exhaust direction, substantially perpendicular to the direction of travel and substantially opposite the first exhaust direction, while discouraging the crop residue from passing therethrough in the second exhaust direction;
wherein the first and second porous apparatus are configured to reduce the volume and velocity of the air flowing through the discharge opening in the housing, to maintain flow of the crop residue in the discharge direction as the crop residue flows through the agricultural harvester discharge guide toward the discharge opening, and to increase the concentration of the crop residue entrained in the volume of air passing through the discharge opening in the housing.

2. The agricultural harvester of claim 1 , wherein the agricultural harvester is adapted for towing a processing implement to receive guided crop residue discharge from the agricultural harvester.

3. The agricultural harvester of claim 2 , wherein the processing implement is a baler.

4. The agricultural harvester of claim 2 , wherein components positioned in a discharge end of the agricultural harvester include components associated with the processing implement.

5. The agricultural harvester of claim 4 , wherein components associated with the processing implement include components associated with providing power and/or control of the processing implement.

6. The agricultural harvester of claim 1 , wherein each porous apparatus is flexible.

7. The agricultural harvester of claim 1 , wherein each porous apparatus is configured to be suspendibly mounted adjacent to the discharge opening.

8. The agricultural harvester of claim 1 , wherein each porous apparatus includes at least one chain.

9. The agricultural harvester of claim 8 , wherein at least one link of the at least one chain is different from another link of the at least one chain.

10. The agricultural harvester of claim 1 , wherein each porous apparatus includes at least one chain having ballast secured thereto.

11. The agricultural harvester of claim 1 , wherein each porous apparatus includes at least one chain having a different length than another chain.

12. The agricultural harvester of claim 1 , wherein each porous apparatus includes a plurality of chains spaced apart from each other.

13. The agricultural harvester of claim 12 , wherein at least one spacing between adjacent chains of the plurality of chains is different.

14. An agricultural harvester comprising an agricultural harvester discharge guide configured to guide crop residue entrained in a volume of air flowing therethrough, the crop residue entrained in the volume of air having an initial concentration, the agricultural harvester discharge guide comprising:
a housing having opposed, first and second sides having corresponding lower ends and a discharge surface spaced from the lower ends of the first and second sides of the housing by first and second air discharge ports, respectively, the first and second sides and the discharge surface defining a discharge opening configured to direct the crop residue in a discharge direction, opposite a direction of travel of the agricultural harvester;
a first porous apparatus suspended over the first discharge port, the first porous apparatus adapted to allow a first portion of the air to pass therethrough in a first exhaust direction, substantially perpendicular to the direction of travel, while discouraging the crop residue from passing therethrough in the first exhaust direction; and
a second porous apparatus suspended over the second discharge port, the second porous apparatus adapted to allow a second portion of the air to pass therethrough in a second exhaust direction, substantially perpendicular to the direction of travel and substantially opposite the first exhaust direction, while discouraging the crop residue from passing therethrough in the second exhaust direction;
wherein the first and second porous apparatus are configured to reduce the volume and velocity of the air flowing through the discharge opening in the housing, to maintain flow of the crop residue in the discharge direction as the crop residue flows through the agricultural harvester discharge guide toward the discharge opening, and to increase the concentration of the crop residue entrained in the volume of air passing through the opening in the housing.

15. The agricultural harvester of claim 14 , wherein the agricultural harvester is adapted for towing a processing implement to receive guided crop residue discharged from the agricultural harvester.

16. An agricultural harvester comprising an agricultural harvester discharge guide configured to guide crop residue entrained in a volume of air flowing therethrough, the crop residue entrained in the volume of air having an initial concentration, the agricultural harvester discharge guide comprising:
a housing having opposed, first and second sides having corresponding lower ends and a discharge surface spaced from the lower ends of the first and second sides of the housing by first and second air discharge ports, respectively, the first and second sides and the discharge surface defining a discharge opening configured to direct the crop residue in a discharge direction, opposite a direction of travel of the agricultural harvester;
a first porous apparatus extending between the lower end of the first side of the housing and the discharge surface and positioned in the first discharge port, the first porous apparatus adapted to allow a first portion of the air to pass therethrough in a first exhaust direction, substantially perpendicular to the direction of travel, while discouraging the crop residue from passing therethrough in the first exhaust direction; and
a second porous apparatus extending between the lower end of the second side of the housing and the discharge surface and positioned in the second discharge port, the second porous apparatus adapted to allow a second portion of the air to pass therethrough in a second exhaust direction, substantially perpendicular to the direction of travel and substantially opposite the first exhaust direction, while discouraging the crop residue from passing theret
