Patent ID: 7093707

Claim:
A grain delivery conveyor for a grain tank of an agricultural combine, comprising: a first gear box including a first input connectable in rotatably driven relation to a rotatable power source for rotation about a first axis, and a first output rotatable about a second axis angularly related to the first axis by rotation of the first rotatable input; a second gear box including a second rotatable input connected in rotatably driven relation to the first output for rotation about the second axis, and a second output rotatably driveable about a third axis angularly related to the second axis by rotation of the second rotatable input; and an elongate conveyor assembly including a rotatable element having first end connected in rotatably driven relation to the second output and a longitudinally opposite free end, the rotatable element being at least partially contained within a longitudinally extending housing, the rotatable element and the housing being jointly pivotable about the second axis for varying a position of the free end relative to the grain tank between at least a first position at a low elevation close to a floor of the grain tank and a second position at a higher elevation in the grain tank, the first gear box being supported for pivotal movement about the first axis such that the first gear box, the second gear box, and the conveyor assembly are jointly pivotable about the first axis for varying a position of the free end relative to the grain tank.
