The production of competitive, ecological agricultural products by agricultural producers in modern conditions is impossible without the modern equipment that provides a combination of technological operations in sowing and fertilizing. As a result of an analytical review of modern coulter designs used in modern seed devices for sowing, planting seeds of grain crops and granules of mineral fertilizers during their application, it was found that the most efficient single disc coulters with press wheels used as gauge-wheels, which ensure high-quality grain crops sowing. The design of the coulter with a gauge wheel of the pneumatic seeder has been developed and its design parameters have been determined. The conducted laboratory field tests of a pneumatic seeder equipped with experimental coulters with a gauge wheel made it possible to determine its optimal design parameters: coulter disc diameter 0.4 m, diameter and width of the copying wheel - 0.27 m and 0.04 m, taking into account the standard deviation of the distribution of seeds at the depth of planting.
В статье рассматривается вопрос повышения качественного показателя посева семян зерновых культур, такого как неустойчивость общего высева и результаты лабораторных исследований экспериментального высевающего аппарата, катушка которого выполнена четырехсекционной, с желобками в форме части поверхности вращения тора. При помощи использования лабораторной установки проведены лабораторные исследования экспериментального высевающего аппарата для нахождения рациональных значений его конструктивных и режимных параметров, необходимых для качественной работы. Получены графические зависимости неустойчивости общего высева от частоты вращения катушки, выполненной четырехсекционной, радиуса образующей части поверхности вращения тора и длины желобка одной секции четырехсекционной катушки. В работе представлены двухмерные сечения графической зависимости, характеризующие неустойчивость общего высева от его конструктивных и режимных параметров экспериментального высевающего аппарата, катушка которого выполнена четырехсекционной, с желобками в форме части поверхности вращения тора, частота вращения катушки, выполненной четырехсекционной, радиус образующей части поверхности вращения тора и длина желобка одной секции четырехсекционной катушки, которые обеспечивают наименьшую неустойчивость общего высева [1, 2]. The article deals with the issue of improving the quality indicator of sowing cereal seeds, such as instability of total sowing and the results of laboratory research of experimental sowing machine, the reel of which is made four-sectional, with grooves in the form of a part of the torus surface rotation. Laboratory researches of experimental sowing machine to find rational values of its design and operating parameters necessary for quality work were carried out using a laboratory set-up. The graphical dependences of instability of total seeding on frequency of rotation of the four-sectional coil, the radius of the forming part of the torus rotation surface and the groove length of one section of the four-sectional wheel were obtained. The paper presents two-dimensional cross-sections of the graphic dependence that characterize the instability of total seeding on its design and operating parameters of the experimental seeding unit, the wheel of which is made four-sectional, with grooves in the form of a part of the torus rotation surface, the rotation frequency of the four-sectional wheel, the radius of the forming part of the torus rotation surface and the groove length of one section of the four-sectional wheel, which provide the lowest instability of the total seeding [1, 2].
