Linear stalk separator with alternating oscillating movements

摘要

Stalk separator for the de-stalking of small fruit picked in bunches, in particular for the de-stalking of grapes. The invention includes a conveyor belt and a de-stalking device positioned above this conveyor belt. The de-stalking device includes at least two spaced assemblies positioned opposite each other, each assembly featuring a number of stacked separator arms. The mechanical drives communicate a high frequency oscillating movement to the assemblies of stacked separator arms.

主权项

1. An apparatus for the de-stalking of small fruit picked in bunches after harvesting, the apparatus comprising:
a flow mechanism for moving the harvested fruit bunches in a flow from an infeed toward an outfeed; a de-stalking mechanism positioned above said flow mechanism, said de-stalking mechanism having at least two berry-detaching assemblies positioned opposite each other and separated by a space forming an open chute, said space being between adjacent surfaces of said at least two berry-detaching assemblies, said space having an infeed end at one end of the two berry-detaching assemblies and an outfeed end at an opposite end of the two berry-detaching assemblies, said space narrowing from said infeed end toward said outfeed end, each of the berry-detaching assemblies having a plurality of separator arms with each arm extending in a plane in spaced relationship and with all arms stacked in a direction perpendicular to their respective planes, each pair of opposed berry-detaching assemblies interacting laterally with the passing fruit bunches over approximately a width of the flow; and a mechanical drive connected to or interconnected to the berry-detaching assemblies so as to impart a high frequency oscillating movement to said plurality of stacked separator arms.
