Abstract: Cleaning device for harvested sugar cane or similar products having a guiding duct (10) which receives, from a throwing assembly (L), cane billets and trash, sending them to a deflecting duct (20) which receives the material through a first inlet (21) communicating with an upper outlet of the guiding duct (10) and placed on a laterally broadened portion of the duct, having a diverging polygonal structure (12) that spreads the material being sent to the deflecting duct (20). The deflecting duct (20) has a body portion (23) provided with curves that spread the billets and trash now-incorporated in a flowing mixture containing air, which was introduced in the deflecting duct (20) through air inlets placed on the upper portion (22) and lower portion (25) of its inlet (21) and through auxiliary lateral air inlets (26) provided on each side of the body portion (23).

Abstract: The invention relates to a harvester of sugar cane or similar products which provides a significant reduction of moving parts and more efficient cleaning of the harvested product than was hitherto possible. This is accomplished by replacing the individual known components for cutting, elevating and cleaning of the cane by a single rotating mechanism provided with a single shaft of reversible rotation and which is fitted with displaceable knives and fixed throwing vanes or wings, which vanes are enclosed in a cylinder with a top outlet discharging the cane billets into a movable duct.

Abstract: A chopping-raising-cleaning assembly for sugar cane harvesting machines in which the operations of cutting the cane into billets, cleaning of said billets and elevation and transport of the billets to a loading position is out by a billet chopping-throwing device in which one rotative or two fixed discharge ducts are attached. According to the present invention the cane is chopped into billets which are thrown into a cylinder having internal rotative fins that move the billets, throwing them upwardly through a tangential opening in the cylinder at a speed sufficient to allow the billets to go up through the corresponding duct, allowing the unloading of the billets on the transport vehicles. The cleaning of the billets is aerodynamically carried out assisted by an extracting fan disposed in each duct.
