Abstract
A hybrid flute for a stalk roll may be configured with a sharp edge positioned between a first blunt edge and a second blunt edge along a length of the flute edge. The flute edge may extend radially outward from a main cylinder of the stalk roll. The flute edge may be engaged with a radius at the base of the flute edge, and a flute base may extend from the radius. A plurality of flute bases positioned adjacent to one another may be configured to form a main cylinder for the stalk roll.
Claims6
A stalk roll (400′) comprising:
- a plurality of flutes (440′, 440a′, 450′, 450a′, 460′), wherein:
- each flute (440′, 440a′, 450′, 450a′, 460′) has a flute edge (442′),
- a main cylinder (430′) including two separable halves, each of the two separable halves capable of connecting or separating from one another transverse to an axis of the main cylinder (430′), and
- one or more support members (404′) protruding radially inward from each of the two separable halves of the main cylinder (430′), wherein the one or more support members (404′) employ at least three planar surfaces (404a′) completely residing within each of the two separable halves of the main cylinder (430′), said at least three planar surfaces (404a′) comprising a subset of at least two planar surfaces (404a′) that are oriented perpendicular to one another;
- and
- a chamfered relief (404b′) located at a corner intersection of two adjacent generally planar surfaces (404a′), so as to prevent unwanted stress and/or damage to the stalk roll (400′);
- wherein said flute edges (442′) extend outward from said main cylinder (430′) in a generally radial direction.
