Abstract

The apparatus for cleaning tuberous plants of this invention comprises a frame, a plurality of digging wheels fastened on the lowermost side of a suitable horizontal framing member at the forwardmost terminal end of the frame, a disk-renk, a belt-renk subassembly, and a discharging subassembly. The disk-renk may include a multiplicity of pentagonally shaped plates fastened on a suitable shaft. The belt-renk subassembly may include a elevating conveyer operable to elevate and to move rearwardly tubers discharged from the disk-renk and a belt-renk disposed parallel to, and substantially beneath, the elevating conveyer, and a upwardly inclined chain conveyer-like belt inclined from its forwardmost terminal end to its rearwardmost terminal end. The chain conveyer-like belt is driven in an upwardly inclined, rearward direction. The discharging subassembly is operable to take plant tubers from the lowermost forwardmost terminal end of the belt-renk and to convey the tubers to a suitable transporting vehicle or similar containing apparatus.

Claims

1. An apparatus for cleaning tuberous plants, comprising

a frame;

a plurality of digging wheels substantially upstandingly mounted to the lowermost side of a suitable, horizontally disposed, framing member at the forwardmost terminal end of said frame;

a disk-renk including a plurality of pentagonally shaped plates fastened on a suitable shaft journally mounted horizontally and transversely on said frame, rearwardly of said digging wheels, said shaft being driven by a suitable drive means;

a belt-renk subassembly including an elevating conveyor and a belt-renk, said elevating being mounted on suitable framing members of said frame and being operable to elevate and to move rectilinearly rearwardly plant tubers from said disk-renk, said elevating conveyor being driven by suitable drive means similar to said disk-renk, said belt-renk being disposed on a suitable framing member of said frame parallel to and substantially beneath said elevating conveyor, said belt-renk including an upwardly inclined, substantially chain conveyor-like belt being driven by suitable drive means driving said belt-renk in an upwardly inclined rearward direction, the angle of said belt-renk being disposed to suitably reduce downward gravitational travel of a tuber on said belt-renk to overcome the counteracting rearward direction of travel of said belt-renk; and

a discharging subassembly being suitable mechanically powered and being carried on said frame, said discharging subassembly having means to collect said tubers discharged from said belt-renk and means to convey said tubers to a transporting vehicle.

2. The apparatus of claim 1, wherein said discharging subassembly comprises a horizontally, transversely disposed conveyer, said conveyer being disposed distally beneath and distally forward of said forwardmost terminal end of said belt-renk, said discharging subassembly including an elevating conveyer operable to elevate and move transversely plant tubers from said horizontal conveyer.

3. The apparatus of claim 2, including a disk-renk comprising a multiplicity of pentagonally shaped plates fastened on a suitable shaft, said shaft being provided with mechanical power from a suitable drive means, said disk-renk being disposed between the interfaces of said horizontal conveyor and said elevating conveyer of said discharging subassembly.

4. The apparatus of claim 1, wherein said plates of said disk-renk are pentagonally configured.
