  • Patent number: 6024178
    Abstract: A direct harvester includes a cutting portion, a lifting portion and a feeding portion. The cutting portion typically includes a cutter rod for severing plant roots and a kicker rod for encouraging the plant to the soil surface. The lifting portion typically includes a rotating pickup head for lifting the plants off the soil and separating the plant from the soil, and a pair of rotating tubes to move the plants and encourage further separation of soil from the plants. The feeding portion includes an auger which receives the plants from the rotating tubes and channels the plants into the opening of a combine feeder housing. Preferably, the floor below the auger is screened to allow soil which is knocked free by the auger to fall back to the ground. Additionally the lifting portion and the feeding portion are preferably pivotably attached to one another to enable the harvester to adapt to differing contours in the soil.

  • Patent number: 5588494
    Abstract: A crop inverter is disclosed for digging and inverting crops, such as peanuts, which have pods disposed below the soil. The inverter typically includes a pair of rotating bars for severing the roots extending downwardly from the pods, and for lifting the pods to the surface of the soil. A pick-up mechanism raises the plants above the ground, and a slinging mechanism removes soil from the pods while conveying the pods to an inverter. The inverter causes the plant to come to rest with the peanut pods on top, without causing unnecessary loss of pods. The inverter typically includes a plurality of augers which extends rearwardly relative to the direction of travel, so that the peanut plants move along the auger until they are ready to be inverted. A mounding plate or other mechanism may also be provided to form a new mound below the row of inverted peanut plants.
