摘要：
The invention relates to agricultural machinery, in particular to the working bodies of tools for subsurface tillage.The working body and includes a rack mounted on it ploskorezhuschuyu paw working surface which is made up of double convex curvature negative - in the undercut portion and positive - in ryhlyaschimi part. Also, it is provided with a radial blade mounted in the longitudinal leg zone axis, made in the form of stabilizers, with the possibility of committing rippers self-oscillatory movements in a vertical plane by means of elastic elements. The working body also includes other knives, made in the form of corrugated toothed discs (turbodiskov) and located behind a paw in the middle zone of its wings, and the cutting edge of each wing has a leg contour rectilinear form under which it is made wavy. Thus BSP radial knife sharpening zone located in the longitudinal axis of the legs, mounted in a hinged paw sock smoothly encircles surface of the paw, and its rear edge is provided with an elastic member in the form of a leaf spring. Wherein the concave and convex portions of the cutting edge alternately performed paw (conjugate) of a circular arc (or the circle of the involute portions), foot sock and - by an arc of a circle (or an arc of an ellipse), and has a one-way sharpening on. The cutting edge is provided with corrugated disks with teeth sided sharpened leading edge portion which is made by a logarithmic spiral and radially arranged circumferentially convex upward curvature to a horizontal plane. Thus the back edge of each tooth is made straight and is perpendicular to the tangent point of the circle corresponding (drive circuit). In addition, the claw chisel contains trapezoidal shape, located in the zone of its sock.Running gear cutting edge paws on the above form helps to reduce garbage and soil provides a sliding cutting and soil deformation with the least resistance.Using the proposed design can improve the quality of the soil, reduce energy ripping
