  • Patent number: 6257978
    Abstract: The invention provides a method and apparatus for recovering food losses from the main recovery system, the handsorters, and the color sorters. A recovery shaker conveyor located beneath the main recovery system to catch food and vines which are tossed off the end of the main recovery system. The food and vines are turned over during the fall, thus loosening some food from the vine. The loosened food falls through the openings in the recovery shaker conveyor onto a recovery cross conveyor which is situated in between the chains of the recovery shaker conveyor and under the handsorters. Food which is rejected by the color sorters also falls onto the recovery cross conveyor and is directed toward a dirt sorter electronic system. The food which is rejected by the handsorters, is placed on a recovery sorter conveyor which is fed into the recovery cross conveyor for re-examination.

  • Patent number: 5908352
    Abstract: The invention provides a harvesting shaker with a set of primary eccentric weights and secondary eccentric weights. The invention rotates the primary and secondary eccentric weights at the same speed, but may on the fly, using a hydraulic rotary actuator, change the rotational phase between the primary and secondary eccentric weights, causing an on the fly change of amplitude of the inventive shaker. The invention also uses a rotary valve, that does not require high pressure bearings, and that provides damping of the control system.

  • Patent number: 5865675
    Abstract: The invention is a harvester which is able to weigh harvested fruit. The harvester transfers the fruit from the harvester by a transfer conveyor. The weighing system is a first shoe and a second shoe supported on the end of the transfer conveyor. A load cell supports the second shoe and is used to determine the weight of the fruit in the second shoe. A linkage system is used to keep the first shoe and second shoe in desired relative positions as the transfer conveyor is moved up or down.

  • Patent number: 5860859
    Abstract: The invention provides an improved method and apparatus for separating fruits, such as tomatoes, from vines. The invention uses feeder bars to provide tomatoes to a shaker brush a first time. The vines are allowed to fall out of the shaker brush to a shaker conveyor. The shaker conveyor conveys the vines into the shaker brush a second time, and then to a vine reel, thus providing an improved separation of tomatoes from the vine.
