Sorting device with conveyor rolls, for removing foreign bodies mixed with fruits harvested from the soil

摘要

The table has a gearbox (19) and a driving motor (20) for driving cylindrical rollers (2) of a sorter system in rotation in same direction for permitting displacement of grape harvest discharged on an upstream part (3) of a sorting plane, in a direction perpendicular to an axis of the rollers and on length of the plane. The rollers are immobilized in translation and placed to provide openings between the rollers to permit passage and fall of grape. Foreign matters having size higher than that of the grape resting on a surface of the plane are evacuated at a downstream end of the plane.
