Harvester sugar cane, a driving system for roll grinders and hydraulic drive system for the transport of harvesting

摘要

A sugar cane harvester is disclosed in which chopped crop is conveyed from a chopping mechanism to a cleaning mechanism. The cleaning mechanism includes an extractor fan positioned in an upper portion of a cleaning cylinder and a substantially unobstructed air intake surrounding the periphery of the cleaning cylinder. The air intake draws air in a generally downwardly direction through the air intake and into the cleaning cylinder, and upwardly through a substantial portion of the crop after the crop exits from the chopping mechanism. Debris is expelled upwardly through the extractor fan, while cleaned crop drops into an elevator for transportation away from the cleaning mechanism.
