摘要：
The utility model relates to agricultural engineering. The section of the ridge seeder contains a suspension, a beam, a gauge wheel, holders, a coulter and a pair of ridge formers. Ridge formers contain a rack, a duckfoot share, a blade and a bracket. The mouldboard is spherical and installed on the inner side of the duckfoot wing at an acute angle to the direction of movement with the possibility of adjusting this angle and moving the dump in height relative to the cutting edges of the duckfoot wings and fixing it in the required position. The concave surface of the dump is directed towards the movement of the ridge former. The dumps of a pair of ridge formers are installed symmetrically relative to the line of sown seeds. A roller is installed behind the ridge formers, which includes a composite frame, an axle and spherical discs freely mounted on it. The frame of the roller is made with the possibility of changing the angle of installation of the side beams together with the spherical discs to the direction of movement and fixing in a given position. Between the spherical discs on the axis with the possibility of free rotation, a rolling drum is installed and is equipped with pointed rippers. Sharpened rippers are installed on the outer surface of the press drum along helical lines, the direction of which starts from the longitudinal axis of symmetry of the press drum and is directed to the end sides of the press drum. In cross-section, the sharpened rippers are diamond-shaped and the sharp edges are directed towards the direction of the roller's movement. The sharpened parts of the rippers are directed in different directions from the geometric axis of rotation of the compacting drum. On the convex side of each spherical disc, rippers are rigidly mounted, having the shape of a circle in cross section. The rippers are mounted on spherical discs around the circumference and the tip is directed towards the longitudinal axis of symmetry of the roller. On the periphe
