ROTARY AMELIORATIVE RIPPER Russian patent published in 2017 - IPC A01B33/16 A01B33/02 A01C21/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building, namely to rotary tillage tools for soil loosening with simultaneous introduction of ameliorants and fertilizers into soil. Rotary ameliorative ripper comprises units of disks with blades installed by means of leads. Cutting blade of knife is made along parabolic curve. Knives are placed on hubs, mounted on axis via plain bearings. Holes are drilled in hubs, conjugated with grooves, made in knives on side opposite blade. Axis has central hole for leads of fertilizers. In zone of knives annular grooves are located on axis. In lower part of axis grooves are connected with radial holes with annular grooves. External part of blade has soil-gripping tip made along radius of circle. In cross section blades are made in form of interfaced hyperbolas, axial lines of which are asymptotes. Fertilizer chutes are tightly connected to central hole on axis, which are connected to discharge cavity of fan connected to fertilizer dosing device.

EFFECT: this design solution provides simplified design of ripper and improved fertility of soil and crop capacity.
