Abstract

An agricultural harvester includes a chassis, at least one ground engaging traction member connected to the chassis, a cleaning system held by the chassis and configured to clean crop material, and an elevator supplied with the crop material. The elevator includes a housing having a crop material inlet that receives the crop material, a boot portion that forms a bottom of the housing, and a plurality of paddles configured to convey the crop material through the housing and away from the boot portion in a generally vertical direction. The elevator further includes a hinged wall section that includes a flexible steel sheet and a UHMW material plastic or other durable wear resistant flexible material overlying the sheet and facing an interior of the elevator. The hinged wall section may be a boot door or a head door.

First claim

What is claimed is:

1. A wall section for a combine elevator having interior walls exposed to crop material, the wall section extending only over an area impacted by crop material comprising:
an outer sheet of flexible steel having a thickness of approximately 1.5 mm for securing to at least one wall of the elevator over at least a portion of an edge of the outer sheet; and
a flexible ultra high molecular weight (UHMW) plastic wear resistant flexible material having a thickness of approximately 4.78 mm overlying an inner face of the outer sheet and having an area not substantially greater than the area of said outer sheet, wherein the outer sheet is curved.

2. The wall section of claim 1 , wherein the outer sheet is one of a boot door and a head door.

3. The wall section of claim 1 , wherein the outer sheet is a head door.

4. The wall section of claim 1 , further comprising a hinge connected to one edge of the outer sheet.

5. The wall section of claim 4 , wherein the UHMW plastic wear resistant flexible material is secured to the outer sheet adjacent the hinge.

6. The wall section of claim 4 , further comprising a removable latch connected to the outer sheet opposite to the hinge.

7. The wall section of claim 1 , wherein the UHMW plastic a UHMW polyethylene flexible material.

8. A crop material elevator, comprising:
a housing including a crop material inlet, a boot portion forming a bottom of the housing, and a top;
a driving loop held within the housing that extends from the boot portion toward the top of the housing;
a plurality of paddles connected to the driving loop and configured to convey crop material away from the boot portion toward the top of the housing;
a first wall section; and
a second wall section at least partially overlapping the first wall section, the second wall section comprising:
an outer sheet of flexible steel secured to the housing at least over at least a portion of an edge of the outer sheet; and
a flexible ultra high molecular weight (UHMW) plastic durable wear resistant flexible material overlying an inner face of the outer sheet and at least partially overlapping the first wall section and having an area not substantially greater than the area of said outer sheet,
wherein the second wall section is curved and is at least one of a boot door and a head door.

9. The crop material elevator of claim 8 , wherein the second wall section is a boot door positioned at the bottom of the housing of the elevator.

10. The crop material elevator of claim 8 , wherein the second wall section is a head door positioned at the top of the elevator.

11. The crop material elevator of claim 8 , further comprising a hinge for connecting the second wall section to the first wall section.

12. The crop material elevator of claim 11 , wherein the UHMW plastic wear resistant flexible material is secured to the outer sheet adjacent the hinge.

13. The crop material elevator of claim 11 , further comprising a removable latch positioned on the second wall section opposite the hinge connection.

14. An agricultural harvester, comprising:
a chassis;
at least one ground engaging traction member connected to the chassis;
a cleaning system held by the chassis and configured to clean crop material; and
an elevator supplied with the crop material cleaned by the cleaning system, the elevator including:
a housing comprising a crop material inlet that receives the crop material and a boot portion that forms a bottom of the housing;
a plurality of paddles configured to convey the crop material through the housing and away from the boot portion in a generally vertical direction;
a first wall section; and
a second wall section at least partially overlapping the first wall section, the second wall section comprising:
an outer sheet of flexible steel secured to the housing of the elevator at least over at least a portion of an edge of the outer sheet; and
a ultra high molecular weight (UHMW) plastic wear resistant flexible material overlying an inner face of the outer sheet and at least partially overlapping the first wall section and having an area not substantially greater than the area of said outer sheet,
wherein the second wall section is at least one of a boot door and a head door.

15. The agricultural harvester of claim 14 , wherein the elevator further comprises a hinge for connecting the second wall section to the first wall section.

16. The agricultural harvester of claim 15 , wherein the UHMW plastic wear resistant flexible material is secured to the outer sheet adjacent the hinge.

17. The agricultural harvester of claim 16 , wherein the elevator further comprises a removably secured latch attached to the second wall section opposite to the hinge.
