SUSPENSION OF ANCHOR PLOUGHSHARE Russian patent published in 2024 - IPC A01C7/20 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to working elements of direct seeders. Suspension of the anchor ploughshare comprises a parallelogram mechanism attached to the transverse beam of the frame, which is a bolted connection of vertically and inclined brackets, and spring with variable rigidity, bracket and cutting disc, to which post is attached anchor ploughshare with possibility of changing its position in horizontal and vertical plane, cleaning scraper. Vertical brackets of the parallelogram mechanism are of different height and protrude beyond its limits. Spring with variable stiffness connects their upper ends. Projection of the vertical bracket attached directly to the frame beam is greater than the projection of the vertical bracket remote from it. Inclined brackets of the parallelogram mechanism are spaced from each other in height at a distance which enables to place between them the transverse beam of the frame and the bracket for attaching the parallelogram mechanism to it. At that, to the cutting disc, on the side of the post, there is a flat disc of smaller diameter with pressing clamps placed on its surface along the perimeter of a circle.

EFFECT: invention will make it possible to exclude uneven depth of the ploughshare and to increase uniformity of seeds embedding into soil.
