  • Publication number: 20210315154
    Abstract: A sugar beet harvest apparatus provides in sequence a pair of field cultivator teeth, a pair of discs or helical screw propellers, and a V-shaped basket of helical screw propellers. The field cultivator teeth and discs may be spaced nominally to engage both sides of a single crop row, or to engage one side of a first crop row, and the opposed side of a second adjacent crop row. In either case, the field cultivator teeth pierce the soil and gently lift the root crop. The discs or helical screw propellers lift the beets and soil into the V-shaped basket of helical screw propellers. Within the V-shaped basket, a pair of ground-level helical screw propellers lift the root crop, while pulverizing the soil and cleaning the root crop. Subsequent helical screw propellers continue to lift the root crop, while pushing rocks and soil rearward proximate to the soil surface.

  • Publication number: 20190350129
    Abstract: A sugar beet harvest apparatus provides in sequence a pair of field cultivator teeth, a pair of discs, and subsequent thereto a V-shaped basket of helical screw propellers. The field cultivator teeth and discs may be spaced nominally to engage both sides of a single crop row, or in an alternative embodiment may be spaced nominally to engage one side of a first crop row, and the opposed side of a second adjacent crop row. In either case, the field cultivator teeth pierce the soil and gently lift the root crop. The discs may flip the beets and soil into the helical screw propellers. A pair of ground-level helical screw propellers lift the root crop, while pulverizing the soil and cleaning the root crop in the process. Each of the helical screw propellers lift the root crop, while pushing rocks and soil rearward proximate to the soil surface.
