摘要：
The invention relates to agricultural machinery, in particular to guns for the surface (minimal) soil treatment. The frame tilling implement sequentially mounted rotary rippers, each of which is disposed in a direction perpendicular to the movement of the shaft with spiral-plate working body with the teeth, where they are formed on the front edge portion of a logarithmic spiral. The working body is fixed to the shaft ends by means of elastic elements radially mounted on the flange. The shafts are interconnected and have a chain transmission means for limiting penetration of working bodies. The working surface of the spiral-plate working organ is made corrugated, each reef which has the form of radial projection of triangular shape. The cutting edge of the working body has a zigzag-shaped (sawtooth) loop formed by paired broken lines extending in a helical line and disposed perpendicular to the direction of movement of the shaft. The working surface of the plate body in the region of its apex - close to the cultivator shaft has a generatrix lying in a vertical plane to the longitudinal axis of the shaft and copying the zigzag-shaped contour of the cutting edge. The shape of the working surface of the plate body is formed by straight zigzag-shaped (broken) conjugated straight lines: straight line with one end of the contour of the cutting edge, and with the other end - along the generatrix situated in its top zone. Each reef (projection) of the working surface of the spiral-plate body has a working surface situated under the sliding angle and is formed as a wedge surface simple dihedral whose height is determined by the formula: . The diameter of the plate body is defined by the relationship: And the number of teeth on its cross-section - from the expression: . The front cutting edge of each tooth is described by the equation: And the length of the rear edge of each tooth is determined from the expression: l T = c-r. Width at the tip of the tooth is defined asПолезная
