Abstract
The apparatus is a fluffing roll for installation on a crop harvesting machine to disperse the crop before it hits the ground thereby facilitating drying. The fluffing roll is a cylinder with auger flights on one half of the cylindrical surface that direct the cut crop in one direction, and auger flights on the other half of the cylindrical surface that direct cut crop in the direction opposite from the direction of the first half.
Claims6
A fluffing roll for dispersing cut crop being discharged from a crop harvesting machine comprising:
- a rotating cylinder structure with a center axis and divided by a radial plane extending from the center axis radially outward into a first partial circumferential cylinder surf ace and at least one other partial circumferential cylinder surface, with the cylinder structure installed in a crop harvesting machine so that cut crop being discharged from the crop harvesting machine strikes the cylinder structure;
- a first set of auger flights attached on one side of the radial plane to the first partial circumferential cylinder surface and moving the cut crop in a first direction along the cylinder structure;
- and
- another set of auger flights attached to at least one other partial circumferential cylinder surface and moving the cut crop in a direction along the cylinder structure opposite from the first direction of cut crop.
