PLOUGH Russian patent published in 2011 - IPC A01B3/00 A01B13/00 

FIELD: agriculture.

SUBSTANCE: plough comprises frames with ploughshares and mouldboards, draw bars, beams, blocks, knives, a hinged device, shock absorbers, chains, left ploughshares. Each frame draw bar has a draw bar bracket and an arched bracket welded to it, and two arcs with coaxial holes are welded to them. The profile of holes in arcs complies with the profile of the left ploughshare base, but slant angles are slightly less than the slant angles of the left ploughshare base. The left ploughshare is inserted with its base into the necessary pair of arc holes at the sharp angle to the direction of movement and is fixed with a stop. The base of the left ploughshare is raised and turned relative to its working part. Also a bracket of a stabilising device is welded to the draw bar bracket with bearings installed in it, where there is an axis with a twisting spring. There is a spherical roller and two combs with teeth installed on the axis. On the hinged device there is a draw bar fixator hingedly installed and controlled with a pneumatic chamber.

EFFECT: structural design will make it possible to increase stability of ploughshare frame travel in a horizontal plane, and also to increase quality of ploughing.
