Straddling tractor grape gathering attachment - has oscillating shaker fingers with grapes falling onto side conveyors and leaves removed by fan

摘要

The attachment fits on a portal type tractor and is used to gather grapes. The tractor staddles the row of vines and the grapes are removed simultaneously from both sides. A set of flexible fingers is provided for each side of the row, these being attached to arms which impart an oscillating movement, adjustable for amplitude. The grapes fall from the vines onto plates guiding them onto a conveyor at each side. Leaves are removed by a fan and the clean grapes pass through a screw conveyor into elevator buckets and a belt conveyor. They are then deposited in a hopper.
