Abstract
Introduction. Laying the groundwork for developing scientific and engineering efforts and for obtaining the results necessary to create technologies, products, goods and services that provide the independence and competitiveness of the domestic agro-industrial complex is one of the main tasks for ensuring the food security of Russia. One of the most important and difficult agricultural operations is sowing carried out by seeders equipped with mechanical, pneumatic or pneumatic-mechanical seed-sowing devices.
Aim of the Article. The purpose of the research is to develop an experimental stand and a methodology for conducting experimental studies of the seed-sowing device for a grain seeder to build mathematical models of its performance when sowing various agricultural crops: wheat, rye, barley, oats, millet, vetch.
Materials and Methods. The mechanical roller feed unit is used on one of the most popular and applicable seeder, namely the universal block-modular seeder SUBM-3.6. It allows ensuring the uniformity of the seeding rate and the exact depth of seed embedding. These indicators are the main ones in assessing the performance of seeders. Considering the design features of the above-mentioned seeder is an important step in assessing its productivity.
Results. One of the main characteristics of the seeders is their productivity. In the article, there are presented the studies aimed at constructing a mathematical model of the dependence of the seeders productivity on the rotational speed of the drive shaft of the working bodies (rollers) pc (min^–1) and the operating length of the rollers lc (mm). For this purpose, an experimental stand and methodology for conducting experimental studies of the productivity of the seeders were developed in accordance with modern methods of experiment planning.
Discussion and Conclusion. The analytical dependences of the seeding rate on the rotation frequency and the roller operating length obtained as a result of experimental studies will allow the most efficient use of roller feed units that in turn will influence the choice of optimal operating modes of the seeder SUBM-3.6.
