Claim:
1. Row divider ( 1 ) applied to a sugar cane harvester ( 100 ), said row divider ( 1 ) comprising at least one helicoidal lift ( 2 ), said helicoidal lift ( 2 ) having a conical shape geometry of variable cross section around an imaginary central axis ( 102 ), and having a first segment ( 3 ) and a second segment ( 4 ), the first segment ( 3 ) establishing a first generatrix ( 5 ) which defines an angle α to the central axis ( 102 ) and having in this first segment ( 3 ) a first screw thread ( 6 ) in its outer surface; and the second segment ( 4 ) establishing a second generatrix ( 7 ) which defines an angle β to the central axis ( 102 ), so that β has a greater value than α and β configures an increase in diameters of the second segment ( 4 ) relative to the first segment ( 3 ), having in this second segment ( 4 ) a second screw thread ( 8 ), which is oriented in the opposite direction of the first screw thread ( 6 ), in its outer surface.
