The technological process of sowing seeds of annual small-seeded crops using the example of flax seeds imposes special requirements to the schemes of existing drilling mechanisms. Currently, in Russia and in other foreign countries, a roller feed remains one of the most popular mechanical drilling mechanisms, but they also do not fully meet the agrotechnical requirements to sow seeds of annual and perennial small-seeded crops. This is primarily due to the physico-mechanical properties of the seeds themselves. As a result, during the operation of the drilling mechanisms, there is an increase in the unsatisfactory spreading of seeds along the length of the row or an uneven seeding space. The stability of the overall seeding rate decreases, which, in turn, leads to increased consumption and bruising of sown seeds. The work is relevant for the agro-industrial complex of the Russian Federation since it is aimed at improving the quality indicators of sowing small-seeded crops using the example of flax seeds of the "Severny" variety by improving its technological process and the design scheme of the sowing mechanism. The article describes the design and technological scheme of the designed drilling mechanism containing a roller with a fine-toothed profile to sow seeds of annual small-seeded crops, such as flax seeds of the "Severny" variety. When working with a new drilling mechanism containing a roller with a fine-toothed profile for sowing flax seeds of the "Severny" variety, the unsatisfactory spreading of the seeds along the length of the groove is reduced, as well as bruising of the seed material, which will further lead to an increase in the biological yield of the crop produced.
Keywords: shape, roller, fine-toothed profile, drilling mechanism, small-seed crops, seeds, seeder.
