Claim 6

A tomato harvester sorting system having a wheel-supported frame carrying all components thereof, wherein tomatoes, after severing of thier vines and late detachment from the vines, are collected and moved rearwardly to a rear cross-conveyor, said harvester also having means for separating dirt clods and loose tomatoes from the vines before said detachment and depositing them on a clod conveyor system, comprising: a horizontal forwardly-moving pre-sorting conveyor receiving tomatoes from said rear cross-conveyor, having an adjacent platform segment for workers to stand on and remove vegetative trash from said pre-sorting conveyor, the tomatoes falling off the forward end of said pre-sorting conveyor, a trash disposal chute in between said pre-sorting conveyor and its said platform segment, an elevating forwardly-moving conveyor having a lower end for catching tomatoes falling from said pre-sorting conveyor and a flighted belt for moving them to an upper end, from which the elevated tomatoes fall, a first cull chute to the rear of said elevating conveyor, a divider above said elevator and said first cull chute for separating tomatoes into a path leading to said elevating conveyor and a path leading to said cull chute, an electromechanical sorter having means for judging the redness or greeness of tomatoes falling from said forward end of said pre-sorting conveyor and mechanical means for impelling green tomatoes into said first cull chute while not interfering with the fall of red tomatoes into said elevating conveyor, an after-sorting conveyor receiving the red tomatoes falling from the upper end of said elevating conveyor and carrying them forward and generally horizontally to an output end and having an adjacent platform segment for workers to stand to remove blemished and overripe fruit therefrom, a second cull chute between said after-sorting conveyor and its platform segment, an outwardly-moving lateral clod conveyor, being the terminal portion of said clod conveyor system, for carrying clods and loose tomatoes outwardly toward the side of said harvester, having a third cull chute at the outer end thereof into which the material on said clod conveyor is conveyed, said clod conveyor being positioned directly over and perpendicular to said elevating conveyor and forward of said electromechanical sorter and having a platform segment adjacent its outer end for receiving a worker for removing good tomatoes from said clod conveyor, and an inclined transfer chute leading from the forward side of said clod conveyor to a locus above said after-sorting conveyor, for receiving good tomatoes removed from said clod conveyor by a worker and for depositing them on said after-sorting conveyor.
