Abstract
The arcuate processing assembly of a combine harvester may be pivotally adjusted generally radially toward or away from a rotary processing device to adjust the operating clearance between the periphery of the rotary device and the assembly. Simultaneously with such adjustment of the assembly as a whole, in a compound pivoting action one arcuate member of the assembly is also pivoted relative to the other arcuate member to properly reshape the threshing region for the adjusted running clearance. Alternative embodiments are disclosed for axial flow and transverse flow systems.
Claims28
In a combine harvester having a rotary crop processing device, the improvement comprising:
- an arcuate processing assembly extending generally in a circumferential direction beneath the rotary device and movable generally radially toward and away therefrom for adjusting the operating clearance between the rotary device and the assembly,
- said assembly including a pair of arcuate members extending successively in a circumferential direction,
- one of said members being adjustably movable toward and away from the rotary device relative to the other member;
- and
- operating mechanism operably coupled with said assembly in a manner to effect said adjustable movement of said one member relative to said other member simultaneously with adjustment of the assembly toward and away from the rotary device.
