STRUCTURAL DESIGN OF A ROLLER SEEDING MECHANISM FOR CROPS OF A GRAIN CROP SEEDER

Abstract

The seeding mechanism is one of the most responsible working bodies of the seeder for sowing crops. In order to obtain high and stable yields, the sowing devices must ensure the following: a continuous and uniform seed flow, the stability of the established seeding rate, the possibility of sowing seeds of various crops, minimal damage to the sown seeds, easy and convenient installation at a given seeding rate. Studies dedicated to improving the quality of sowing crops by improving the technological process of operation of the coil sowing apparatus are relevant and have important economic importance for the agroindustrial complex of Russia. The article presents the design and principle of operation of the developed roller seeding mechanism, which sectional coil grooves of are made in the shape of a torus, providing longitudinal stability of sowing seeds of grain crops, uniform distribution of seeds along the row and reducing injuries to seeds of cultivated crops. Because the grooves of the sectional coil are made in the form of a torus, this maximizes the working volume of the sectional coil, makes it possible to reduce the frequency of rotation of the sectional coil, the instability of the general seeding rate, improve the uniformity of seed distribution along the length of the row, reduce damage to the seeds and increase the yield of the cultivated crop.
