DRUM FOR THRESHING DEVICE Russian patent published in 2009 - IPC A01F12/20 A01F12/18 

FIELD: agriculture.

SUBSTANCE: present invention pertains to agricultural engineering, particularly to combine harvesters. The drum of the threshing device consists of discs mounted on an axle. The discs are in form of circular plates with openings and centre bosses. Along the periphery of the circular plates, rails with pins are mounted using figured plates with openings, which are rigidly joined to the inner surface of rails. The discs form separate sections, inside of which rails with pins are mounted along the periphery. Openings on the circular and figured plates provide for regular or irregular positioning of rails with pins inside each section, independent of the number of rails with pins in neighbouring sections.

EFFECT: reduced labour input when making the threshing drum and its easier servicing and repair.
