Abstract
Air assisted harvesting means having a manifold extending transversely across the cutter bar platform of a harvester with a plurality of tubes depending therefrom, and nozzles on the tubes arranged to discharge air streams some of which at least partly overlie the air streams of others, so as to provide a deep rearwardly moving air curtain.
Claims12
Air assisted harvesting means comprising an air manifold, mounting means for mounting the air manifold transversely at the front end of a harvester over a cutter bar assembly, a plurality of air distributor tubes depending from the manifold and in fluid flow communication therewith, rearwardly directed nozzles on the lower ends of respective said tubes, the transverse width of each nozzle being greater than its height, and the nozzles being inclined relative to the cutter bar assembly and transversely to the longitudinal axis of the harvester such that, in use, a portion of the pattern of the air stream discharge from each of said nozzles at least partly overlies, in a vertical plane, the pattern of discharge from at least one respective adjacent nozzle.
Air assisted harvesting means comprising an air manifold, mounting means for mounting the air manifold transversely at the front end of a harvester, at least two rows of air distribution tubes depending from the manifold and in fluid flow communication therewith, rearwardly directed nozzles on the lower ends of respective said tubes, the tubes of one of the rows being different length than the tubes of the other row such that, in use, a portion of the pattern of the airstream discharge from each of said nozzles at least partly overlies, in a vertical plane, the pattern of discharge from at least one respective adjacent nozzle.
