Chopping-raising-cleaning assembly for sugar cane harvesting machines

摘要

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.
