Abstract

A system having a frame, an auger operably coupled to the frame, an auger wrapper fixed to the frame and proximal to the auger, the auger wrapper having a curved surface with a first rigidity, and a liner attached to the auger wrapper, the liner comprising a second rigidity that is less rigid than the first rigidity.

First claim

At least the following is claimed:

1 . An auger-based system used in processing of crop material, comprising:
a frame; an auger operably coupled to the frame; an auger wrapper fixed to the frame and proximal to the auger, the auger wrapper comprising a curved surface with a first rigidity; and a liner attached to the auger wrapper, the liner comprising a second rigidity that is less rigid than the first rigidity.

2 . The system of claim 1 , wherein the auger wrapper is comprised of metal.

3 . The system of claim 2 , wherein the auger wrapper comprises an opening and the liner is centered about the opening.

4 . The system of claim 3 , wherein the liner is either:
fixably attached to the auger wrapper along, and adjacent to, a bottom of the opening and removably attached to the auger wrapper along, and adjacent to, a top of the opening; or fixably attached to the auger wrapper along, and adjacent to, the top of the opening and removably attached to the auger wrapper along, and adjacent to, the bottom of the opening.

5 . The system of claim 3 , wherein the liner is removably attached to the auger wrapper along, and adjacent to, a top and bottom of the opening.

6 . The system of claim 3 , wherein the liner is fixably attached to the auger wrapper along, and adjacent to, a top and bottom of the opening.

7 . The system of claim 3 , wherein the liner is disposed between the auger and the opening.

8 . The system of claim 3 , wherein the opening is disposed between the auger and the liner.

9 . The system of claim 3 , wherein the auger wrapper comprises plural tabs adjacent to a lower surface of the auger wrapper and the liner comprises a lip running along an upper end of the liner and plural slots adjacent to and running along a lower surface of the liner, each of the plural tabs inserted through the respective plural slots to form lower end removable attachments between the auger wrapper and the liner, wherein plural latches are coupled between the lip and an upper surface of the auger wrapper to form upper end removable attachments between the auger wrapper and the liner.

10 . The system of claim 1 , wherein the liner is comprised of a metal material or a non-metal material.

11 . The system of claim 1 , wherein the liner, when at least partially detached from the auger wrapper, loses a curvature formed from the attachment to the auger wrapper.

12 . The system of claim 1 , wherein the liner has more elasticity than the auger wrapper.

13 . The system of claim 1 , wherein the liner comprises one or more uncovered openings.

14 . A disc/rotary mower header, comprising:
a frame comprising a front portion and a rear portion; plural rotary discs coupled laterally along the frame and proximal to the front portion; one or more augers operably coupled to the frame and disposed laterally and adjacent the plural rotary discs; one or more auger wrappers coupled to the frame and disposed rearward from, and adjacent to, the respective one or more augers; and for at least one of the auger wrappers, one or more liners attached to the at least one of the auger wrappers, the at least one of the auger wrappers less flexible than each of the one or more liners.

15 . The disc/rotary mower header of claim 14 , wherein for at least one of the one or more liners, the at least one of the auger wrappers comprises an opening and the at least one of the one or more liners is centered about the opening.

16 . The disc/rotary mower header of claim 15 , wherein the at least one of the one or more liners is fixably attached to the at least one of the auger wrappers along auger wrapper surfaces surrounding the opening.

17 . The disc/rotary mower header of claim 15 , wherein the at least one of the one or more liners is at least partly removably attached to the at least one of the auger wrappers along auger wrapper surfaces adjacent the opening.

18 . The disc/rotary mower header of claim 14 , wherein the at least one of the one or more liners is comprised of metal having elasticity.

19 . The disc/rotary mower header of claim 14 , wherein the at least one of the one or more liners is comprised of a non-metal material.

20 . An auger-based system used in processing of crop material, comprising:
a frame; an auger operably coupled to the frame; an auger wrapper fixed to the frame and proximal to the auger, the auger wrapper comprising a first rigidity; and a liner attached to the auger wrapper, the liner comprising a second rigidity that is less rigid than the first rigidity.
