  • Patent number: 10537918
    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: 7591377
    Abstract: A vibrating screen aggregate separation device separates finer grained material from an aggregate material that may contain a wide variety of undesired materials. A mesh design associated with a vibrating screen contains perforations to allow smaller diameter material to pass through into a container that is situated below the screen. A suspension system is affixed between the container and the vibrating screen to allow a range of motion that is conducive to vibration of the screen, while at the same time, is supportive of the weight of the aggregate material that is to be screened. Vibration of the screen is effected by rotating an unbalanced rod along its longitudinal axis to induce vibrational energy to the screen and associated supporting structures.
