DEVICE OF DISK TYPE FOR EMBEDDING BULBS IN FURROW Russian patent published in 2013 - IPC A01C5/00 A01C7/20 

FIELD: agriculture.

SUBSTANCE: embedding body is a convex spherical disc with a cutting edge, on the working surface of which the circular holes with soil-guides are made, located on the inner surface of the disc. The generator of the soil-guides is deflected from the radial direction at an angle of not less than 5°. The angle of curvature of the surface profile of the soil-guides between the tangent at each point and the direction of flight of the particles is 2-3° greater than the angle of friction of the soil.

EFFECT: invention enables to improve the quality of embedding the bulbs on the surface of the soil-guide.
