Abstract:
1. A crop pick-up apparatus for attachment to a feeder house of a combine harvester comprising: a pick-up frame including mountings arranged for attachment of the pick-up frame to the feeder house for movement in a direction of forward movement with the combine harvester; a crop pick up assembly mounted on the frame and comprising a plurality of parallel transverse bars extending transversely across the pick-up frame; the bars being arranged generally around and parallel to a transverse axis of the pick-up frame which axis is at right angles to the direction of forward movement; each bar having a first end and a second end and supporting a plurality of tines at spaced positions along the bar between the first and second ends thereof and extending therefrom generally outwardly relative to the transverse axis; and a drive arrangement for moving the bars in a composite movement both around the transverse axis and parallel to the transverse axis; the composite movement being arranged such that each tine of the bars describes a respective closed path of travel around the transverse axis, which closed path is inclined to a radial plane of the transverse axis; the composite movement being arranged such that the first end of the bars describes a first closed path of travel around the transverse axis, which first path is inclined to a radial plane of the transverse axis; the first path of travel defining an innermost end of the first path closest to the center line of the feeder house and an outermost end furthest away from the center line of the feeder house; the composite movement being arranged such that the second end of the bars describes a second closed path of travel around the transverse axis, which second path is inclined to a radial plane of the transverse axis; the second path of travel defining an innermost end of the second path closest to the center line of the feeder house and an outermost end furthest away from the center line of the feeder house; a belt conveyor mounted on the frame behind the crop pick up assembly so as to receive the crop therefrom for transporting the crop rearwardly, the belt conveyor having a first side edge and a second side edge; a converging auger behind the conveyor and including an auger roller with auger flights thereon so as to converge the crop inwardly from the first and second side edges of the belt conveyor toward a discharge opening of the pick-up frame aligned with the feeder house for feeding the crop into the feeder house; wherein the belt conveyor is offset to one side relative to the first and second paths of the first and second ends of the bars; so that the second side edge of the belt conveyor is spaced outwardly to the side relative to the second path to a greater extent than the first side edge relative to the first path; and so that the second side edge extends beyond the outermost end of the second path of travel.
