Attachment for rotary material processing machines
A material processing machine with a rotating element positioned within a hopper for receiving materials to be processed, the rotating element including an outer edge to which one or more attachments may be mounted. The attachments include a forward edge extending generally forward with respect to the direction of rotation of the rotating element and extending outward from the outer edge of the rotating element. A rotating element for use in a material processing machine has either attachments mounted to an outer edge or integrally formed extensions along an outer edge. The extensions or attachments including a forward edge that extends generally forward with respect to the direction of rotation of the rotating element.
1. A material processing machine including a rotating element, the material processing machine comprising:
a hopper for receiving and processing material, the rotating element mounted within the hopper and configured to engage the material within the hopper;
the rotating element including helical flighting positioned about a central axis of rotation, and rotating in a direction of rotation, the flighting including an outer edge and configured to rotate so that the flighting engages the material within the hopper;
at least one attachment mounted to the outer edge of the flighting, the at least one attachment extending beyond the outer edge of the flighting;
the attachment including a sharpened edge, the sharpened edge having an inner sharpened edge portion adjacent the outer edge of the flighting, the inner sharpened edge portion extending forward, considering the direction of rotation of the rotating element, and outward away from the outer edge of the flighting, so as to hook the material and pull the material apart.
2. The material processing machine of claim 1 wherein the attachment includes a mounting portion adjacent the inner portion of the forward edge, the mounting portion configured to permit the mounting of the attachment to the flighting.
3. The material processing machine of claim 1 wherein the forward edge of the attachment includes a bevel so that the forward edge has a narrower profile to aid in processing material engaged by the rotating element.
4. The material processing machine of claim 1 wherein the attachment further includes a body with an outer extension of the body extending further from the axis of rotation of rotating element than the outer portion of the forward edge.
5. The material processing machine of claim 1 wherein the outer portion of the forward edge of the attachment defines the furthest extension of the attachment from the axis of rotation.
6. The material processing machine of claim 1 , further comprising a plurality of attachments mounted to the outer edge of the flighting of the rotating element.
7. The material processing machine of claim 1 wherein the outer edge of the flighting includes an extension to which the attachment may be mounted.
8. The material processing machine of claim 1 , further comprising a mount secured to the flighting adjacent the outer edge of the flighting, the mount providing a mounting location for the attachment.
9. The material processing machine of claim 8 wherein the mount includes a recess within which the attachment may be mounted, and the attachment includes one or more outer edges that extend beyond the recess.
10. A material processing machine including a rotating element, the material processing machine comprising:
a hopper for receiving and processing material, the rotating element mounted within the hopper and configured to engage the material within the hopper;
the rotating element including helical flighting positioned about a central axis of rotation and rotating in a direction of rotation, the flighting including an outer edge and configured to rotate so that the flighting engages the material within the hopper;
at least one extension integrally formed along the outer edge of the flighting, the at least one extension extending beyond the outer edge of the flighting;
the at least one extension including a forward sharpened edge, the forward sharpened edge having an inner sharpened edge portion adjacent the outer edge of the flighting, the inner sharpened edge portion extending forward,
considering the direction of rotation of the rotating element, and outward away from the outer edge of the flighting, so as to hook the material and pull the material apart.
11. The material processing machine of claim 10 , wherein the forward edge of the extension includes a bevel so that the forward edge has a narrower profile to aid in processing material engaged by the rotating element.
12. The material processing machine of claim 10 wherein the extension further comprises a body with an outer extension, the outer extension extending further from the axis of rotation of rotating element than the outer portion of the forward edge.
13. The material processing machine of claim 12 wherein the outer extension includes a bevel so that a cutting edge is defined by the outer extension.
14. The material processing machine of claim 10 wherein the outer portion of the forward edge of the extension defines the furthest extension of the attachment from the axis of rotation.
15. The material processing machine of claim 10 , further comprising a plurality of extensions integrally formed along the outer edge of the flighting of the rotating element.
