  • Publication number: 20240101365
    Abstract: A conveyor for transferring debris that falls from an end dump conveyor to a main incline conveyor. A cleanup conveyor is attached to an end dump conveyor of a crop piler. The upper run of the cleanup conveyor is positioned below a lower run of the end dump conveyor and is adapted to receive debris that falls from the lower run of the end dump conveyor. The outer end of the cleanup conveyor is near a main incline conveyor of the crop piler to transfer the debris that falls from the lower run of the end dump conveyor to the main incline conveyor of the crop piler.

  • Patent number: 11890645
    Abstract: A piler conveyor system for screening debris such as tare dirt from materials such as beets as the materials are conveyed across a piler. The piler conveyor system generally includes a frame supporting an upper conveyor and a pair of lower conveyors. The upper conveyor is adapted to receive materials such as beets. As the materials are conveyed by the upper conveyor, debris such as tare dirt or the like will fall through screening openings in the upper conveyor and onto the lower conveyor. The lower conveyor may then dispense the debris through a debris opening. The materials will drop off the end of the upper conveyor and fall onto the second lower conveyor, which will convey the screened materials to be dispensed.

  • Patent number: 11634283
    Abstract: A paddle conveyor system for efficiently removing tare, dirt, small particles, and other debris from large bulky products such as sugar beets. The paddle conveyor generally includes a first pulley including a first side and a second side and a second pulley including a first side and a second side. A first linkage is connected between the first side of the first pulley and the first side of the second pulley and a second linkage is connected between the second side of the first pulley and the second side of the second pulley. A plurality of paddles is each connected between the first linkage and the second linkage such that the plurality of paddles forms a loop for conveying a material towards the second pulley. Each of the paddles includes one or more slots through which debris from the material may fall.

  • Patent number: 11564353
    Abstract: A crop cart unloading system for efficiently unloading a harvested crop from a crop cart. The crop cart unloading system generally includes a hopper having a floor conveyor movably positioned with respect to a lower floor, a plurality of sidewalls extending upwardly from the lower floor, an unloading door movably connected to an unloading end of the hopper, and an upper opening defined by an upper edge of the plurality of sidewalls for receiving a field crop. The hopper is pivotally connected to a support frame having a plurality of wheels. A first actuator is connected between the support frame and the hopper to lift the unloading end of the hopper. An unloading conveyor is attached to the unloading end of the hopper to receive and discharge a field crop from the hopper.

  • Patent number: 9555676
    Abstract: A hydraulic towing system for use with towing vehicles lacking hydraulics including a hydraulic housing which is mounted to a towing device. The hydraulic housing includes an internal compartment which stores a hydraulic system for controlling the towing device. A reservoir, pump, and control are used to control flow of hydraulic fluid through a plurality of hydraulic conduits. First and second hydraulic conduits are linked with a lift actuator which acts to transition the towing device between a lowered position for use and a raised position for storage. Third and fourth hydraulic conduits are linked with a catch actuator, which acts to mount the towing device to a towed vehicle by extending an engaging member to through a hitch of the towed vehicle. Thus, a self-contained hydraulic system may be provided for a towing device where the towing vehicle does not include its own hydraulic system.
