PLOUGH BODY Russian patent published in 2019 - IPC A01B15/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to plowshares. Body of the plow contains a stand with field boards (2), blade (3) and blade (4) mounted on it. Field board (2), plowshare (3) and blade (4) are connected into one whole and form a lay-dump surface with the contour of the section of guide (7) of the specified surface in the form of a spiral fragment and a horizontal generatrix. Horizontal forming lay-dump surface is made in the form of a fragment of a spiral. Angle between the beginning and the end of the specified fragment in the polar coordinate system is less than 180°, and the radius of curvature at any point of the spiral is equal to the value of the functional dependence: R =ƒ(ϕ), where R is the radius of curvature, and ϕ - the angle of rotation of the radius vector, and ϕ∈[0.180].

EFFECT: improved quality of plowing and reduced energy intensity of the process.
