摘要：
The utility model relates to agricultural machinery, in particular to combined rotary implements for pre-sowing tillage. The tool consists of a welded frame 1 and a linkage mechanism 2. A horizontal shaft 4 is mounted on the frame 1 on the bearing bearings 3. Horizontal disks 6 are mounted on the shaft 4 on the bearing bearings 5, on which a spiral 7 of rectangular cross section is rigidly fixed with left and right winding symmetrically the connecting ring 8. The spiral 7 is inclined to the generatrix of the cylindrical surface at an angle δ>； ϕ tr , where ϕ tr is the angle of friction of the spiral sliding on the soil. The coils of the spiral 7 are interconnected, as well as with the disks 6 and the ring 8 with square spiral rods 9 with left and right windings. On the shaft 4, needle-shaped ellipsoid disks 10 are coaxially fixed, driven by a hydraulic motor 11. The design parameters of the disks 10 are determined by the formulas a = D / (2 sin α), b = D / 2, where a , b are the major and minor semi-axes of the ellipses , D are the diameters of the disks in the projection onto the profile plane, α is the angle of the disks on the shaft. Needles 12 of the discs are mounted on a ferrule 13 with an inclination backward at an angle β>； ϕ tr , where ϕ tr is the angle of friction of the sliding of the needles on the soil. The large axes 2a of the ellipses of the adjacent disks 10 are rotated one relative to the other around the axis of the shaft clockwise or counterclockwise by an angle γ = 180 / (n-1), where n is the number of ellipsoidal disks. The utility model provides a simplification of the design and increase the efficiency of pre-sowing tillage.Полезная модель относится к сельскохозяйственному машиностроению, в частности к комбинированным ротационным орудиям для предпосевной обработки почвы.
