摘要：
The disc coulter is a two-line disc drive related to agricultural machinery , in particular to disc seeders of seeders.The technical result is achieved by the fact that the device has two pairs of disk working bodies, of which the lateral have the form of flat discs and are installed at some angle to the direction of movement, and the internal ones are in the form of truncated cones and are mounted on coaxial semiaxes connected by a coupling with the possibility of adjusting the distance between them . The angle of inclination of the lateral generatrix of internal disc organs to the base is equal to the angle between the plane of the side disc and the longitudinal plane of the opener, and the common axial line of the internal semi-axes is perpendicular to the longitudinal plane of the opener. The lateral and internal semiaxes are connected in pairs and motionless at an angle defining the angle of attack of the side disc to the longitudinal plane of the opener, and additionally comprise brackets for fastening to the opener coupler,Stepless adjustment of the distance between the rows of the opener is carried out by untwisting the coupling, with the angle of attack and the roll angle of the discs remaining unchanged, which ensures that the profile of the furrows is maintained unchanged.The device is placed on the drill by attaching brackets to the suspension mechanism. In this case, the point of closest approach of a pair of disk opener working bodies must be below the surface of the soil, but above the surface of the soil sulcus.The balancing of the lateral power components of the soil reaction on each pair of discs is provided by their angular geometry and contributes to the stabilization of the transverse position of the entire opener when the drill moves, which ultimately contributes to the high straightness of the formed sowing furrows. The shape of the sowing furrow is created and retained by the surfaces of pairwise installed flat and conical disks, which facili
