CULTIVATION CORRUGATED SPHERICAL DISK Russian patent published in 2020 - IPC A01B23/06 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, and namely to cultivating machines. Cultivating corrugated spherical disc has a corrugated surface on an outer ring smoothly conjugated with a smooth surface of its central part. On circle passing through points of disk blade, equidistant from planes of tangents to blade at crests tops of its convex and concave sides, distance between adjacent points of blade with ridge between them on convex side of disc, at least, one and a half times more than distance between points of blade with comb between them on its concave side. Length of arc between equally located relative to corrugation points of blade on this circle is equal to 2 πr/n, where r is radius of circumference, and n is number of pairs of corrugations, containing crest on convex and concave side of disc.

EFFECT: higher intensity of crushing of dry strong blocks and stability of disk without sticking well-moistened soil.
