摘要：
The utility model relates to agricultural machinery, and specifically to tillage implements. To reduce energy consumption and improve the quality of the process in a plow body with a feather blade, including a rack 1, to which a shoe 2 is attached, to which a ploughshare 5 is attached using fastening elements 3 and 4 , the chest of the blade 6, the strip of the blade 7 and the field board 8, the upper 9 and lower 10 forming the strip of the blade 5 have an angle τ with the bottom of the furrow, determined by the formula: where τ is the angle between the tangent to the path and the horizontal straight line oh (bottom of the furrow) drawn through the point of tangency in a tangent plane to the surface, degrees； E - soil elastic modulus, MPa； J is the moment of inertia of the section of the formation relative to the neutral axis directed normal to the surface, kg⋅m； η is the angle in the sweep between the tangent to the relative trajectory of the formation and the blade of the share, deg； s is the arc of the relative trajectory, measured from the point of this curve, corresponding to the transition from the movement of the formation along the ploughshare and chest of the dump to the movement along the dump, m； T - compressive force in a given section of the reservoir, N； - thickness of the reservoir (plowing depth), m； b - reservoir width, m； g is the acceleration of gravity, m / s； V is the relative velocity of the formation, m / s； γ is the specific gravity of the formation, g / cm； ε is the dihedral angle between the tangent plane and the plane of the bottom of the furrow, deg.Полезная модель относится к сельскохозяйственному машиностроению, а конкретно к почвообрабатывающим орудиям.Для снижения энергоемкости и повышения качества технологического процесса в корпусе плуга с перьевым отвалом, включающем стойку 1, к которой крепится башмак 2, к которому при помощи элементов крепления 3 и 4 крепятся лемех 5, грудь отвала 6, полосы отвала 7 и полевая доска 8, верхние 9 и
