Abstract
Abstract A field crop harvester comprising a four-wheel vehicle with a crop-gathering header at the forward end having a sickle cutter and associated apparatus for gathering grain crops and delivering the same to a feeder blower which raises the material into the cone-shaped end of a horizontally disposed threshing cylinder which is mounted on an axis extending longitudinally of the vehicle frame, a horizontally disposed separator mounted on the same longitudinally extending axis and having an auger within a perforated tube which advances the material to a discharge opening at the rear of the tube, the threshing cylinder and separator extending through a grain storage tank disposed forwardly of the center of the vehicle and having associated grain augers disposed horizontally on parallel shafts which carry the separated grain from the threshing cylinder and the separator to a vertically disposed cleaner at the rear of the vehicle, which cleaner includes an auger mounted on a vertical axis enclosed within a perforated tube, which in turn is mounted in a cylindrical housing with a fan at the top for drawing the trash into a discharge chute while the grain thrown through the perforated tube drops to a collecting pan at the bottom and is directed into a slinger for transfer through a cooperating chute to a storage tank from which it may be withdrawn through an unloader slinger and chute.
