  • Publication number: 20090223683
    Abstract: The machine for removing ferrous debris removes such debris from firing ranges where the removal of hard objects is desired to prevent ricochets during firing exercises, particularly on aircraft gunnery ranges. The machine includes a chassis towed behind a remotely controlled or automated vehicle, with a mechanism support frame pivotally mounted on the chassis. A series of magnetic operating arms is provided across the mechanism frame, with a chain drive conveyor cycling the operating arms as the machine is operated. The operating arms automatically release any gathered ferrous debris into a hopper as the arms reach the hopper during their cycle. A mechanism is provided to accommodate angular deflection of the operating arms relative to the hopper due to sloped terrain, and a further automated mechanism is provided to tilt and empty the hopper as required. No human operator is required in the immediate area of the machine.

  • Patent number: 7165628
    Abstract: A harvester for root crops such as beets is provided which preferably provides continuous flow of root crops from a header, along a transfer assembly, through a processing run, and to an elevator assembly. The harvester can be configured to include or accommodate interchangeable header assemblies having different numbers of rows and/or row spacings. The transfer assembly can be of a floating type and helps to provide an even distribution of beets to the grabrollers. The processing run includes full-length cleaning grabrollers disposed parallel to the direction of travel. Modular elevator assemblies can be provided to further enhance harvester versatility. Such an approach includes interchangeable ferris wheel and scrubber chain elevator assemblies. An improved scrubber chain elevator assembly can be used which has a wraparound scrubber chain design. A pivoting tank conveyor for evenly filling a holding tank can be included.

  • Patent number: 6206104
    Abstract: A tool, for mounting on a tractor or backhoe having a three or four point hitch to pivotally mount the tool on a laterally extending horizontal axis for vertical motion and for pivotal motion about the horizontal axis, provides a frame having connecting structure to releasably interconnect with the hitch and extracting structure to move in and beneath an arborescent root system to lift that system from the earth in which it is resident. The connecting structure provides spaced pivot pins to pivotally interconnect with the lifting arms of the hitch and one or two spacedly distant tilt arm brackets to interconnect with the tilting arm or arms of the hitch. The extracting structure provides a plurality of elongate extracting tines, at least some of which have elongate fins depending therefrom to direct motion in the earth, that are carried in laterally spaced relationship by an elongate, laterally extending lowermost beam of the frame to extend distally from the hitch.

  • Patent number: 5386876
    Abstract: A machine for removing strips laid out on the ground has a rotary reception unit for winding a strip at a distance from the ground to form a reel, and a driving unit for driving the reception unit for rotation. A drum is mounted so as to rotate. The strip passes over the drum before reaching the reception unit. Rotary brushes are arranged in such a way that the strip passes between the brushes and the drum so that the strip is brushed and the material from the ground accumulated on the strip is removed therefrom. The brushes are provided with a device for driving the brushes for rotation.

  • Patent number: 5366023
    Abstract: A wagon pulled along a plant bed for retrieving buried drip tape includes a cultivator disc for loosening the soil to free the drip tape which is then drawn upward and onto the wagon through the use of a rotating drum that rotates at such a speed that its surface moves at the ground speed of the wagon. A wringer wheel that bears against the drum extracts water and air from the drip tape, which is then wound onto a reel under the control of an operator for subsequent storage and reuse. This mode of retrieval is considerably faster than manual retrieval thereby reducing labor cost, and the reuse of the drip tape saves disposal costs as well as material costs and results in conservation resources of the resources used in manufacturing the drip tape.
