Agitator assembly for a fruit-vine separator

Claim 2

An agitator assembly for use in combination with an apparatus for separating fruits such as tomatoes from the vines of the plant, the separating apparatus being of the oscillatory type including a pair of longitudinally extending side frame members, a pair of shafts mounted transversely between the front and rear ends of the side frame members, a plurality of parallel endless conveyors having spaces therebetween through which separated fruits may fall and parallel reaches for conveying the vines, said conveyors being supported on said shafts, means for synchronously oscillating said side frame members in fore-and-aft directions parallel to said conveyors, and means for simultaneously continuously driving said conveyors in a direction of travel, said agitator assembly comprising: a member mounted transversely between said side frame members below said reaches of said conveyors; and a plurality of agitator bars rigidly mounted to said transverse member in parallel relationship and at intervals aligned with the spaces between said conveyors; each agitator bar having an upstream face which is upwardly inclined in said direction of travel of the conveyors at a selected acute angle relative to the conveyor reaches and with the upstream faces of said agitator bars extending above the conveyor reaches, whereby the vines on the conveyors are lifted as the vines are conveyed in said direction of travel and are dropped back onto said conveyors as they move over the agitator bars to hence facilitate the movement of the fruit downwardly through the vines.

Claim 3

The agitator assembly according to claim 1 wherein said transverse member is adjustably mounted to said side frame members of said separator to enable said bars to be adjusted at various selected acute angles relative to the reaches of said conveyors.

Claim 4

The apparatus according to claim 2 further comprising means for adjusting the height of said transverse member relative to said side frame members of said separator, thereby also enabling the adjustment of the height of the upper ends of said bars above said conveyors.

Claim 5

In a vine crop harvester having a mobile framework and harvesting means on said framework adapted to cut a row of vines and to carry the vines and fruit attached thereto to a discharge area, an improved separator apparatus comprising: conveyor means extending under said discharge area for carrying the vines and fruit deposited thereon, said conveyor means including a plurality of parallel transversely spaced endless conveyors, each conveyor having means for entangling and moving the vines, the upper reaches of said conveyors being supported at their upstream and downstream ends on transversely extending shafts and said shafts being mounted between the ends of a pair of longitudinal said frame members; delivery means directly below said conveyor means for receiving fruit falling between the upper reaches of said plurality of conveyors; means mounted on said harvester frameword for oscillating said side frame members and thus said shafts in a direction generally parallel to the direction of movement of said upper reaches of said conveyors; a member mounted transversely between said side frame members below said upper reaches of said conveyors; and agitator means mounted to said transversely extending member and extending upwardly from said transversely mounted member for lifting the vines and fruits suspended thereon from said upper reaches of said conveyors and for causing said vines and fruits to cascade back to said conveyors after they have been lifted therefrom to thereby decompact the vines and thus facilitate the movement of the fruit through the vines to the delivery means, said agitator means including a plurality of bars that are rigidly mounted to said transversely extending member to project upwardly through said conveyor reaches and forwardly at selected angles relative to said reaches.

Claim 6

In a vine crop harvester having a mobile framework and harvesting means on said framework adapted to cut a row of vines and to carry the vines and fruit attached thereto to a discharge area, an improved separator apparatus comprising: conveyor means extending under said discharge area for carrying the vines and fruit deposited thereon, said conveyor means including a plurality of parallel transversely spaced endless conveyors, each conveyor having means for entangling and moving the vines, the upper reaches of said conveyors being supported at their upstream and downstream ends on transversely extending shafts and said shafts being mounted between the ends of a pair of longitudinal said frame members; delivery means directly below said conveyor means for receiving fruit falling between the upper reaches of said plurality of conveyors; means mounted on said harvester frameword for oscillating said side frame members and thus said shafts in a direction generally parallel to the direction of movement of said upper reaches of said conveyors; a member mounted transversely between said side frame members below said upper reaches of said conveyors; and agitator means mounted to said transversely extending member and extending upwardly from said transversely mounted member for lifting the vines and fruits suspended thereon from said upper reaches of said conveyors and for causing said vines and fruits to cascade back to said conveyors after they have been lifted therefrom to thereby decompact the vines and thus facilitate the movement of the fruit through the vines to the delivery means, said agitator means including a plurality of bars that are rigidly mounted to said transversely extending member to project upwardly through said conveyor reaches and forwardly at selected angles relative to said reaches.

Claim 7

In a fruit-vine separator of the type comprised of a separator frame, a plurality of endless conveying means including a plurality of chains arranged in spaced parallel relationship on said frame, means for continuously driving said conveying means, and means for continuously reciprocating said conveying means in planes generally parallel to the direction of conveying movement of the conveying means, the improvement comprising a member that is rigidly mounted to said separator frame to extend transversely of said conveying means, an agitator bar uprightly and rigidly connected to said transverse member so as to reciprocate therewith, said agitator bar being positioned on said transverse member between two of the chains of said conveying means and extending upwardly above said chains and forwardly at a selected acute angle therewith in the direction of travel of the chains, whereby said agitator bar serves to lift the vines from the conveying chains to aid in the delivery of fruit through the separator to an underlying fruit collector.

Claim 8

In a fruit-vine separator of the type comprised of a separator frame, a plurality of endless conveying means including a plurality of chains arranged in spaced parallel relationship on said frame, means for continuously driving said conveying means, and means for continuously reciprocating said conveying means in planes generally parallel to the direction of conveying movement of the conveying means, the improvement comprising a member that is rigidly mounted to said separator frame to extend transversely of said conveying means, an agitator bar uprightly and rigidly connected to said transverse member so as to reciprocate therewith, said agitator bar being positioned on said transverse member between two of the chains of said conveying means and extending upwardly above said chains and forwardly at a selected acute angle therewith in the direction of travel of the chains, whereby said agitator bar serves to lift the vines from the conveying chains to aid in the delivery of fruit through the separator to an underlying fruit collector.
