Abstract: Disclosed is a rotor and cage assembly that includes a skeleton of curved spaced-apart side members affixed to laterally extending upper and lower spaced-apart members therebetween and surrounding the rotor. One of the curved spaced-apart side members is terminated with curved fingers. Three concave inserts insert laterally into the skeleton spanning 270° around the rotor. One of the concave inserts carries straight fingers that interlace between the skeleton side member curved fingers. A control assembly of plates having arcuate slots placed at 3 of the pivots of the skeleton assembly, control bars connected to the skeleton pivots, and an actuator connect to the control bars at one end effect arcuate rotation of the control bars resulting in the synchronized rotation of the arcuate slotted plates so that the interlaced straight fingers move closer together or farther apart with the fixed skeleton assembly curved fingers for different types of grain.

Abstract: A grain harvesting articulated combine includes of a crop processing power unit (PPU), a rear grain cart, and an articulation joint that connects the PPU with the rear grain cart. The articulation joint includes a transverse drawbar attached to the PPU about its rear, which has an aperture facing the rear grain cart and is located underneath the PPU forwardly of the rear of the powered PPU. An arcuate beam is attached to the rear of the powered PPU. A grain auger assembly runs from the PPU to the rear grain cart. The grain auger assembly has a forward end and a rear end and is formed from an outer tube and an inner tube rotatingly carried within the outer tube. A pin runs through the transverse drawbar aperture and a bracket aperture. A pair of articulation cylinders is affixed to the transverse drawbar and to the outer tube.
