  • Patent number: 6419028
    Abstract: A harvester for ground surface crops is an array of bars connected to cross-members, each bar having an obtuse-angulation toward the front end of the bar. The arrays describe surfaces which may be curved or substantially planar on either side of the obtuse angle. The bars are spaced closely enough to be smaller than the size of the parts of the plants of the ground surface crop to be harvested, and spaced far enough apart to permit weeds and other debris to drop between the bars to the ground. The harvester apparatus is used by moving it forward, front end first, along the ground sufficiently into the soil surface to slip underneath the crop-parts to be gathered. As the front parts of the bars slips underneath the crop-part to be gathered, the crop-part is lifted from the soil by the forward motion of the harvester and ramped upward and rearward along the incline of the bars, and is thereby detached from the soil surface.

  • Patent number: 5577562
    Abstract: The stems and limbs of a root crop plant are lifted from the ground, folded over a gathering bar, and grasped by an auger-paddle. The roots below the crop are severed by a cutter bar which resembles a rod weeder. While the crop is held the soil beneath the crop is pulled from the be in which the crop grows into a furrow on either side of the bed. As much as possible the root crop is cleaned as it is lifted up by the rotation of the paddle-auger while the limbs and stems of the plant are caught within the paddle-auger and held by the helicoil. After they are lifted free of the soil they are moved from two beds toward a furrow between those two beds and discharged in a windrow by a roller which rotates the opposite direction of the paddle-augers.

  • Patent number: 5069292
    Abstract: A method and related apparatus is provided for size reduction and separation of soil clods mixed with a root crop. The method includes the steps of feeding the mixture along an enclosed operative path, manipulating the mixture so as to change the shape of the conveyed mass and break up the soil clods sufficiently to reduce the size and separating the clods from the crop. The manipulation preferably takes the form of shifting the clods longitudinally and laterally with respect to each other. The operative path is preferably serpentine in shape with the clods/crop expanding along the outside of bends and contracting along the inside of bends. The serpentine path is oriented in a substantially vertical direction and may provide differential speeds along the boundaries of the path. The optimum mixture is approximately 50% soil clods at the entry end, with the range being between 35% and 65%.

    Abstract: Tomatoes are mechanically harvested by moving a mechanical harvester through a row of growing tomato plants, severing the plants below ground, and picking up the severed plants along with loose tomatoes and some dirt clods, while returning loose dirt to the ground. The severed tomato plants are separated from the loose tomatoes and dirt clods and are shaken to remove the tomatoes from the plants. These tomatoes are recovered and conveyed forwardly past sorters. In the meantime the originally loose tomatoes and clods are passed rearwardly countercurrently to the mainstream of tomatoes, by the sorters for recovery of good loose tomatoes. Preferably, the pickup is made at about 15% slower than the ground speed of the harvester, while the separation between plants and the clods and loose tomatoes is made at the ground speed and the separated plants are carried away from that separation step at a speed about 15% greater than the ground speed of the harvester.
