  • Patent number: 4899527
    Abstract: A horizontal boom extends laterally from a superstructure and includes a boom belt conveyor which receives harvested fruit from upwardly extending belt conveyors. The boom conveyor carries fruit to an inner discharge end above the superstructure for discharge into a vertical passage and then into a container at the bottom of the passage. A downwardly moving vertical conveyor forms one side of the passage and has rows of deformable fingers which lower fruit into the container. A sheet forming the opposite side of the passageway moves the entire vertical conveyor upwardly in response to accumulation of fruit within the container, while the vertical conveyor continuously moves in a downwardly conveying direction to carry fruit to the container.
