Patent ID: 7861851

Claim:
An extractor apparatus for moving grain from a grain bag, the apparatus comprising: a frame mounted for movement along the ground in an operating travel direction; a substantially vertically oriented main auger attached to a rear end of the frame such that an intake end thereof is above the ground and in proximity to the ground; a knife mounted to the frame and configured to extend rearward from the main auger to cut the grain bag; a turret auger pivotally attached to a top end of the main auger such that the turret auger extends laterally from the main auger, and can pivot with respect to the main auger; a feed auger extending laterally right and left of the intake end of the main auger, and configured to auger grain to the intake end of the main auger; a pair of pinching rollers mounted on the frame forward of the main auger and above the ground such that the pinching rollers are oriented substantially perpendicular to the operating travel direction; a bias element operative to force the pinching rollers against each other; a drive operative to rotate the pinching rollers such that an empty portion of the grain bag can be fed between the pinching rollers and the pinching rollers rotated to pull the empty portion of the grain bag upward from the ground and forward between the pinching rollers such that the empty portion of the grain bag falls on the ground in front of the pinching rollers as the frame moves rearward, and such that the frame is pulled rearward and the feed auger moves rearward into a filled portion of the grain bag.
