DEVICE FOR LASER PROCESSING OF SEEDS BEFORE SOWING Russian patent published in 2008 - IPC A01C1/00 

FIELD: farming.

SUBSTANCE: device includes a charging hopper, a transporter to move seeds, a laser source and a line scan knife-edge of a laser source beam. The device has a roller with knife edges spaced from each other and intended to transform the beam into several vertical flatnesses. The roller has a horizontal rotation axle, and the line scan knife edge of the laser source beam has a vertical rotation axle. The roller with the knife edges is installed on the opposite side of the transporter with respect to the position of the knife edge of the laser source line scan. The rotation axle is arranged above the horizontal beam line scan flatness of the said knife edge to reflect its beams to the transporter flatness. The roller knife edges are dismountable and made in quantity of 2 to 12 knife edges. The line scan knife edge of the laser source beam is shifted with respect to the laser source beam in the horizontal flatness.

EFFECT: increased sowing and productivity qualities of seeds and lowered labour intensity.
