DRIVE OF CUTTING DEVICE Russian patent published in 2010 - IPC A01D34/30 A01D34/32 A01D34/37 

FIELD: agriculture.

SUBSTANCE: drive of cutting device includes body with traction rods and elastic elements installed in it. Each traction rod is connected to knife strip and is arranged in the form of rotor in cylindrical linear induction electric motor. Stator of electric motor is rigidly installed on body and consists of equal parts, arranged so that windings of one part are the continuation of windings of the other part. Windings of stator parts are connected so that electromagnetic forces applied to rotors are directed into opposite sides. In proposed drive electric energy is only spent for motion of knife strips towards one side. Reverse motion of strips is achieved with energy accumulated in elastic elements.

EFFECT: increased reliability of cutting device.
