Technical solution for providing optimal seeding depth and improving the contact of small seed crops with wet soil when seeding

Abstract

The article describes an invention that relates to agricultural machinery, namely to seeders for sowing grass seeds and grain crops, in areas with insufficient moisture and soils susceptible to wind erosion. The objective of the invention is to provide the optimum depth of seeding, in particular, of small-seeded crops and herbs, when sowing on treated and untreated backgrounds in soil-protective, minimal and “zero” tillage systems. The technical result of the invention lies in the fact that the distinguishing features of a grain-seeder seeder provide an optimal seeding depth and improved contact of small-seeded crops, in particular grass seeds with moist soil, when sowing in soil-protective, minimal and “zero” tillage systems. The proposed seeder, the coulters are rigidly connected to the frame by means of rods, which allows the coulters to withstand the same predetermined depth on soils of different hardness. The initial formation of sowing grooves is carried out installed before the coulters, in their longitudinal plane of symmetry, at an angle 55-65 degrees to the horizontal, revolving cutter knives with a wear-resistant coating of the working part. There are two packer roller rollers pivotally connected to the frame with a cylindrical rim, while the batteries are spring loaded with the ability to adjust the pressure of the rollers on the soil.
