ABSTRACT:
A seed harvester is provided for harvesting seeds from a standing crop without cutting the crop. The harvester is particularly designed for harvesting grass seed. The harvester includes a header assembly for stripping from the crop, and a seed separator for drawing the seeds from the header assembly in an air stream and for separating the seeds from the air stream. The header assembly includes a frame assembly having a transverse inlet which communicates with the seed separator. An endless revolving stripping surface is mounted across this transverse opening to contact the seed heads of the crop and strip the mature seeds from the crop. A rotating reel is mounted to rotate parallel to, and above and forwardly of, the seed stripping surface. On rotation, the reel guides the crop into contact with the seed stripping surface and holds it there for a time to permit the seed stripping surface to remove mature seeds from the crop. The seed separator includes a duct, curved between its ends. The duct inlet communicates with the transverse inlet of the header assembly. A blower is provided at the duct outlet to draw seeds in an air stream, from the header assembly and through the duct. Baffles are provided across the curved duct section which, together with the curve in the duct, cause the seeds to move outwardly toward the outer wall of the curved duct section. This achieves partial separation of the seeds from the air stream. To achieve the remainder of the separation, the seed separator includes a seed withdrawal duct in the outer wall of the curved duct section, and a sealed container at the end of the seed withdrawal duct. Air is drawn through the container and the seed withdrawal duct, preferably by the blower, to carry the seeds in an air stream into the container.
