Stalk roll
A flute for a stalk roll has a sharp edge defined by the relationship of the leading surface and a leading wall. The flute is positioned on a main cylinder of said stalk roll having a leading surface having its base nearer the main cylinder and its top farther from the main cylinder, the leading wall, and a trailing wall. The leading wall extends perpendicular to and outward from said main cylinder. The base of the leading surface intersects the leading wall and travels upwardly to intersect with the trailing surface to form an edge. The angle between the leading wall and leading surface is thirty degrees.
1. A flute for a stalk roll, said flute comprising:
a) a flute positioned on a main cylinder of said stalk roll having a leading surface having a base nearer the main cylinder and a top farther from the main cylinder, a leading wall and a trailing wall;
b) wherein the leading wall extends perpendicular to and outward from said main cylinder;
c) wherein the base of the leading surface intersects the leading wall and travels upwardly to intersect with a trailing surface to form a flute edge; and
d) wherein the angle between the leading wall and leading surface is thirty degrees;
e) a beveled edge beginning at a front axial surface of the flute;
f) wherein the flute is configured such that, as the flute rotates toward the leading surface and the leading wall, cutting occurs at a stalk cut point, that depending on a rotational position of the stalk roll, is adjacent to one of the following two locations: (i) a smooth, convex surface of the base at an area where the base is oriented parallel to an outer surface of the main cylinder; and (ii) the beveled edge; and
g) wherein said flute and said stalk roll are further defined such that said flute does not extend along an entire length of the main cylinder of said stalk roll.
2. The flute according to claim 1 wherein the flute edge is sharp.
3. The flute according to claim 1 wherein said stalk roll further comprises a plurality of flutes positioned on said main cylinder.
4. A flute for a stalk roll used in the harvest of corn having a stalk, said flute comprising:
a) a flute positioned on a main cylinder of said stalk roll having a leading surface having a base nearer the main cylinder and a top farther from the main cylinder, a leading wall and a trailing wall;
b) wherein the leading wall extends perpendicular to and outward from said main cylinder;
c) wherein the base of the leading surface intersects the leading wall and travels upwardly to intersect with a trailing surface to form a flute edge; and
d) wherein an angle between the leading wall and leading surface positions the base of the leading surface to contact said corn stalk prior to the flute edge contacting said corn stalk;
e) a beveled edge beginning at a front axial surface of the flute;
f) wherein the flute is configured such that, as the flute rotates toward the leading surface and the leading wall, cutting occurs at a stalk cut point, that depending on a rotational position of the stalk roll, is adjacent to one of the following two locations: (i) a smooth, convex surface of the flute-base at an area where the base is oriented parallel to an outer surface of the main cylinder; and (ii) the beveled edge; and
g) wherein said flute and said stalk roll are further defined such that said flute does not extend along an entire length of the main cylinder of said stalk roll.
5. The flute according to claim 4 wherein the flute edge is sharp.
6. The flute according to claim 4 wherein said stalk roll further comprises a plurality of flutes positioned on said main cylinder.
7. The flute according to claim 1 wherein the flute edge occurs at a vertex of the leading surface and the trailing surface.
8. The flute according to claim 1 wherein a recess is located within the main cylinder.
9. The flute according to claim 1 further comprising a mount that allows the flute to attach to the main cylinder such that the flute rotates toward the leading surface and the leading wall.
10. The flute according to claim 1 wherein the trailing wall and trailing surface are integral and linear.
11. The flute according to claim 4 wherein the flute edge occurs at a vertex of the leading surface and the trailing surface.
12. The flute according to claim 4 wherein a recess is located within the main cylinder.
13. The flute according to claim 4 further comprising a mount that allows the flute to attach to the main cylinder such that the flute rotates toward the leading surface and the leading wall.
14. The flute according to claim 4 wherein the trailing wall and trailing surface are integral and linear.
