摘要：
The utility model relates to agricultural engineering, and specifically to tillage implements. To reduce the energy consumption of soil cultivation in a plow body containing a rack 1, to which a shoe 2 is attached, to which a share 3 is attached, a field board 4 and a blade 5, consisting of a dump blade 6 , the wings of the blade 7, field 8 and the furrow edge 9, while the working surface of the blade 5 is made in such a way that its orthogonal sections of the surface of the blade 5 with secant planes are S-shaped curves, and the lower part is concave, and the top is convex, the curvature of the curves of which along the orthogonal sections increases in the direction from the field edge 8 to the furrow 9, and each curve of this section is variable with a decrease in its curvature in the direction of the inflection point, the working surface of the blade 5 has a shape with sections formed secant planes that are parallel to the tangent to the trajectory of the formation on the chest of the blade 6 in the form of S-shaped curves concave on the chest of the blade 6 and convex on the wing of the blade 7 with radii of curvature, providing deformation of the bending of the formation, and not more than the value determined by the expression: where R is the radius of curvature, mm； k is the proportionality coefficient characterizing the parameters of plowing； a is the depth of plowing, mm； b is the width of the plowing, mm, while the curvature S- figurative sections made variable in height of the blade 5, with the least curvature will have the section of the lower part of the blade 5, and the greatest - the upper part of the blade 5.Полезная модель относится к сельскохозяйственному машиностроению, а конкретно к почвообрабатывающим орудиям.Для снижения энергоемкости обработки почвы в плужном корпусе, содержащем стойку 1, к которой крепится башмак 2, к которому крепится лемех 3, полевая доска 4 и отвал 5, состоящий из груди отвала 6, крыла отвала 7, полевого 8 и бороздового об
