FIELD: agriculture.SUBSTANCE: ploughshare comprises parallel working and rear surfaces, a cutting edge, two mounting holes. The ploughshare has wing geometric shape, namely, a rear part convex from the side of the working surface, the front part of the ploughshare folded inwards along the movement of the harvesting unit and two separating ellipse-shaped holes, located in parallel one above the other at an acute angle to the cutting edge, on the convex part in the zone of a root crop exit. The separating holes have chamfers on the working surface of the lower part of the ellipse along the movement of the root crop and the chamfer along the entire circumference of the ellipse on the rear side of the ploughshare.EFFECT: increased efficiency of cleaning of root crops at the time of rooting out, reduction of resistance between soil and the working surface.2 dwg |
