  • Patent number: 4677813
    Abstract: 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 downward 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. A energy absorbing plate is mounted in the cleaning area to contact crop billets as the billets leave the chopping mechanism. The plate is adjustably mounted to contact greater or lesser amounts of the crop after the crop passes through the chopping means.

  • Patent number: 4483129
    Abstract: A device to adjust the length of billets in a cane harvester. Hydraulic motors of different fluid throughput capacity drive chopper rolls which are mechanically connected. The outlet of one of the motors conveys fluid through a connection to the feed rolls which convey the cane to the chopper rolls. The outlet connection of a second of the hydraulic motors is interchangeable so that the fluid from either motor may pass to the feed rolls as desired.
