ABSTRACT:
A tomato harvester sorting system. Tomatoes from a rear cross-conveyor are caried forwardly by a pre-sorting conveyor where workers remove vegetative trash. An electro-mechanical sorter judges the redness or greenness of tomatoes falling from the forward end of the pre-sorting conveyor and impels green tomatoes into a cull chute, while red tomatoes fall on to an elevating conveyor. An after-sorting conveyor receives red tomatoes from the upper end of the elevating conveyor and carries them forward to an output end, while workers remove blemished and overripe fruit. A tiltable, outwardly-moving clod conveyor, being the terminal portion of a conveyor system for clods and loose tomatoes, has a cull chute at its outer end. The clod conveyor is positioned directly over the elevating conveyor. A worker removes good tomatoes from the clod conveyor and places them in the main sorting stream with the red tomatoes.
