Sugar Beet Harvest Apparatus
First Claim
1. A root crop harvest apparatus, comprising:
- a frame having a coupling adapted to mechanically couple with a tractor;
at least one field cultivator affixed to said frame and having a ground piercing tooth;
at least one disc affixed to said frame, displaced from and trailing said at least one field cultivator along a longitudinal axis of said root crop harvest apparatus; and
at least four helical screw propellers affixed to said frame, displaced from and trailing said at least one field cultivator and said at least one disc along said longitudinal axis of said root crop harvest apparatus;
a first pair of said at least four helical screw propellers arranged in a V-shaped configuration within a plane immediately adjacent to and generally parallel to a surface of the earth; and
a second pair of said at least four helical screw propellers arranged in a V-shaped configuration within a plane parallel to and above said plane defined by said first pair of said at least four helical screw propellers, and extending more distally to said at least one field cultivator than said first pair of said at least four helical screw propellers.

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.

15. A sugar beet harvest apparatus configured to traverse and harvest sugar beets grown in parallel rows within the earth, said parallel rows defining a direction of sugar beet harvest apparatus travel, comprising:
-
a frame having a coupling adapted to mechanically couple with a tractor; a pair of field cultivators affixed to said frame, each of said pair of field cultivators having a ground piercing tooth; a pair of discs affixed to said frame, displaced from and trailing said at least one field cultivator along a longitudinal axis of said root crop harvest apparatus; and at least four helical screw propellers affixed to said frame, displaced from and trailing said at least one field cultivator and said at least one disc along said longitudinal axis of said root crop harvest apparatus, each individual one of said at least four helical screw propellers having a rotary hydraulic motor coupled to and driving a rotary shaft having a helically wrapped screw thread; a first pair of said at least four helical screw propellers arranged in a V-shaped configuration within a plane immediately adjacent to and generally parallel to a surface of the earth; and a second pair of said at least four helical screw propellers arranged in a V-shaped configuration within a plane parallel to and above said plane defined by said first pair of said at least four helical screw propellers, and extending more distally to said at least one field cultivator than said first pair of said at least four helical screw propellers.
