Abstract
A dual action corn cob separation and attendant corn cob separator, having a plurality of generally vertical or generally longitudinally elongated slots, and having disposed therebetween at least two of said slots, at least one generally vertical or longitudinal in-line row of smaller slots or openings, whereby whole corn cobs can be more effectively harvested.
Claims10
An improved cob separation grate section for a combine harvester to separate corn cobs from the stalks and leaves, comprising:
- a plurality of vertical or longitudinally disposed and latitudinally spaced apart elongated slot openings, each slot extending the substantial height of the grate;
- two or more of said slots being separated therebetween by a longitudinal row of in-line smaller openings, said row also extending the substantial height of the grate and substantially parallel to the direction of the elongated slots;
- and
- said grate having a peripheral row of in-line smaller slots located at a forward end and a back end of the grate;
- whereby cobs are passable through the slots but not the smaller openings, and whereby the corn gain is passable through the smaller openings but most MOGC is not passable.
2 more elements
An improved method for separating corn cobs from material other than corn cobs, comprising:
- providing a dual action separation having corn separated in an initial concave front section of an axial flow combine harvester having a rotor moving corn material in a direction of flow, and having said corn cobs substantially whole being separated from material other than corn or cobs at a rear grate section, having a plurality of vertical or longitudinally disposed slots, said slots being wide enough to accommodate the diameter of a cob, but long enough to longitudinally extend for the substantial entirety of the grate's height, and said slots being separated by at least one in-line row of smaller openings also extending substantially entirely the height of the grate, whereby whole corn cobs are harvested.
