Hydraulic system for collecting crop grain and crop residue in a single pass

摘要

A harvesting system for collecting crop grain crop residue in a single pass with a baler towed by a combine harvester is provided. The system includes a hydraulic system that hydraulically interconnects the combine harvester with the baler, allowing the engine of the combine harvester to hydraulically power systems and components of both the combine harvester and the baler. The hydraulic system may include a combine hydraulic system and a baler hydraulic system which may be hydraulically connected through multiple interconnections for hydraulically powering different functions of the baler using hydraulic pressure that is generated at the combine harvester. A first combine-to-baler hydraulic interconnection may transfer hydraulic power from a combine primary baler drive hydraulic circuit to a baler drive hydraulic circuit. A second combine-to-baler hydraulic interconnection may transfer hydraulic power from a combine spreader hydraulic circuit to a baler conveyor and/or auxiliary hydraulic.

1. A harvesting system for collecting a crop grain and a crop residue material in a single pass while harvesting a crop from an agricultural field during a harvesting session, the harvesting system comprising:
a combine harvester for harvesting the crop from the agricultural field and threshing the crop into separated constituents including the crop grain and the crop residue material, wherein the crop grain is temporarily stored in the combine harvester during the harvesting session until a grain unloading event and the crop residue material is discharged out of the combine harvester during the harvesting session; a baler having a baling chamber and towed behind the combine harvester for baling the residue material in the baling chamber and including a conveyor extending between the combine harvester and the baler to move the crop residue material discharged out of the combine harvester to the baling chamber for forming of the bales therein; and a hydraulic system including:
a combine ground drive hydraulic circuit delivering power for moving the combine harvester;a spreader hydraulic circuit with spreader drive motors arranged in the combine harvester for rotating spreader disks to discharge the crop residue material out of the combine harvester;a conveyor hydraulic circuit receiving hydraulic power from the spreader hydraulic circuit and arranged to drive the conveyor of the baler, the conveyor hydraulic circuit includes a conveyor drive motor receiving hydraulic power from the spreader hydraulic circuit and configured to power rotation of a belt of the conveyor;a combine primary baler drive hydraulic circuit separate from the combine ground drive hydraulic circuit; anda baler drive hydraulic circuit receiving hydraulic power from the combine primary baler drive hydraulic circuit and delivering power to the baler for powering the forming of the bales in the bale chamber of the baler.
