Abstract

This disclosure relates to a power operated swingable auger conveyer which can be moved from operative discharge position conveyer at right angles to the vehicle supporting the conveyor to an inoperative discharge wherein the conveyer lies alongside the vehicle.

Claims

1. In a combine harvester having an operator'"'"''"'"'s platform, a grain bin and an auger type grain unloading conveyor positioned adjacent the bottom portion of said bin, the improvement comprising an auger and tube assembly adapted to form an operative extension of said unloading conveyer and positionable in a transport position extending parallel in plan to the longitudinal axis of said harvester and positionable in an unloading position extending at right angles in plan to said harvester, said unloading conveyer including a tube extending from said grain bin and presenting an angled end portion at its outboard end which end portion faces rearwardly, means pivotally mounting said auger and tube assembly on said angled end portion for pivotal movement about an axis passing through the center of said angled end portion so that said auger and tube assembly extend outwardly at substantially right angles in plan to the longitudinal axis of said harvester when in unloading position and the outer end of said tube is provided with ground clearance and side clearance so vehicles can move under the outboard end of said tube for receiving grain in the center of said vehicle, said auger and tube assembly generating a segment of a cone when pivoted from said transport position to said unloading position with the apex of said cone being in the center of said angled end portion, said cone having an Included angle of 96*, and said assembly extends upwardly and outwardly from said harvester at approximately an angle of 25* relative to the ground when in unloading position.
