FIELD: agriculture.SUBSTANCE: cutting edge of a ploughshare is bent along the path towards the face surface, at the same time the angle of deviation of the entire cutting edge from the bottom of the furrow is directly proportionate to the product of the elastic component of relative compressive deformation and ploughing depth, and inverse to the blade length.EFFECT: improved process reliability of a ploughshare.3 dwg |
