Abstract

The purpose. To develop the design of boot consolidating positive performances of double-circular and hoe boots, working on coarsely prepared with plant residues soils and stably ensuring depth of seeding on the heightened speeds of sowing. Methods. Mathematical simulation, experimental and statistical. Probes of the combined double-circular hoe boots at sowing by selection-seed-growing seeder SN-16 in the assembly unit with tractor T-25 are carried out at seeding millet in field seed-fallow row-crop rotation on dark-chestnut medium-loamy soil. Results. Parameters of the combined double-circular hoe boot with the improved gear of regulation of depth of drilling of seeds are justified. On the basis of the equivalent main circuit of construction of the boot necessity of application of spring of the set rigidness for provision of stability of seeding seeds on the set depth within the limits of agrotechological the tolerance is justified. Dependences for calculation of rational spring rate which consider geometrical parameters of construction of the boot are gained. Probes in field conditions confirm advantages of new designs. Conclusions. The seeder with the combined double-circular hoe boot stacks seeds on solid seeds bed, eliminates lag of removal of seeds for limits of agrotechological tolerance, including on the heightened speeds of sowing and covering rollers which are fixed with an opportunity of regulation of the position. That is advantages of boots with new designs.
