CULTIVATOR WORKING TOOL Russian patent published in 2018 - IPC A01B35/22 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly to tillage tools. Working body of the cultivator contains a C-shaped spring-loaded cradle on the frame with a pendulum vibro-impact mechanism and an upper impact limiter. Pendulum impacter interacts with a height-regulated semi-spherical anvil of an elastic C-shaped vibro-impact strut on one side and with a hemispherical anvil of an elastic cantilever with adjustment of the installation angle by means of a sector mechanism. Drummer is made in the form of a hollow cylinder fixed with the possibility of adjusting the pendulum arm at the end of the lever with an internal vibro-impact mechanism. Internal vibro-impact mechanism consists of alternating coil springs and cylindrical bodies with hemispherical protrusions at the ends and protruding cylindrical pushers interacting with the hemispherical anvils of the column and the elastic stop. Movement of the working element in the vertical direction is limited by a vibro-impact limiter consisting of a pair of impactors and a cylindrical compression spring.

EFFECT: such a constructive solution provides for reducing the energy intensity of the soil treatment process, improving the crumbling quality and ensuring the stability of the specified depth of the working body.
