Abstract
A sugar cane combine harvester having a topper/shredder in advance of a crop divider mechanism with the crop divider aiding in moving sugar cane to a knock down feed roll, base cutters, a feed roll system, a chopping system including a cleaning system, and an elevator system. The chopping system propels cut cane and debris into a cleaning system where the cane and debris are subject to an air stream generated from a single variable speed blower. The cane and debris in a cleaning chamber are forced upwardly into contact with the rear wall of the cleaning chamber set at an angle of 60 to 75 degrees. The lighter debris is forced to continue up and out through a discharge duct and onto the ground behind the harvester. The cane falls by gravity onto a loading platform to be conveyed to a transit vehicle.
Claims20
A sugar cane combine harvester comprising:
- a chassis,
- a topper mounted on said chassis for cutting tops of sugar cane stalks,
- a crop divider mechanism mounted on said chassis for lifting and separating sugar cane,
- a knock down roller mounted on said chassis for bending sugar cane away from the chassis,
- at least one base cutter mounted on said chassis for cutting a base of the sugar cane,
- a chopping system mounted on said chassis for cutting the sugar cane into pieces, and
- a cleaning system for separating debris from cut pieces of sugar cane, said cleaning system including a variable speed blower fan for separating debris from cut pieces of sugar cane released from the chopping system by blowing air towards the debris released from the chopping system, said cleaning system including a cleaning chamber having an inclined rear wall positioned to aid debris be expelled from said cleaning chamber and for the cut pieces of cane to fall by gravity from said cleaning chamber.
A sugar cane combine harvester comprising:
- a chassis,
- a crop divider mechanism mounted on said chassis for lifting and separating sugar cane,
- a knock down roller mounted on said chassis for bending sugar cane to expose a bottom portion,
- a base cutter mounted on said chassis for cutting the bottom portion of the sugar cane,
- a chopping system mounted on said chassis for cutting the sugar cane into pieces,
- an elevator system for elevating the pieces of sugar cane from the feed and chopping system and releasing the pieces of sugar cane to another conveyor for processing of the sugar cane, and
- a cleaning system including a cleaning chamber having a rear wall for separating debris from cut pieces of sugar cane, said cleaning system including a blower fan for separating debris from cut pieces of sugar cane released from the chopping system by blowing air towards the debris released from the chopping system so as to force the debris towards the rear wall of the cleaning chamber and to allow the cut pieces of sugar cane to fall by gravity.
