Abstract
A machine for lifting sugar beets from the soil, separating the soil and foreign matter from the sugar beets and elevating the sugar beets for loading on a transport vehicle. The machine has beet lifting wheels which lift the beets from the soil and direct the beets to link conveyors. The conveyors carry the beets to one end of a grab and cleaning roller assembly. The grab and cleaning roller assembly has a plurality of smooth and spiral ribbed rollers that are rotated to clean and move the beets the length of the roller assembly to a disc assembly. The disc assembly comprises a plurality of discs that are rotated in a direction to move the beets to the inlet area of a loading elevator. The loading elevator is independently supported on the ground with a wheel assembly. Adjusting structure is used to adjust the heighth of the elevator. Separate controlled hydraulic motors are operable to drive the conveyors, the disc assembly and the loading elevator. A pump mounted on the machine is operable to deliver hydraulic fluid under pressure to the separate hydraulic motors.
