DEVICE FOR HEADER OF COMBINE HARVESTER FOR SUNFLOWER HARVESTING Russian patent published in 2023 - IPC A01D75/02 A01D45/30 A01D41/12 

FIELD: agriculture.

SUBSTANCE: device for the header of a combine harvester for harvesting sunflower, containing a segment-finger cutting apparatus, a finger bar attached to the combine body, to which dividers with restrictive collars on the sides are attached. The limiting collars of the dividers are made along a radius R equal to the sum of the right angle and the angle of friction of the achene on the surface of the divider, followed by bending to the angle of friction of the achene on the surface of the divider relative to the horizontal plane, having a length up to the intersection with the vertical plane from the edge of the flange. The radius R is equal to the length of the achene.

EFFECT: reduction of grain loss during sunflower harvesting.
