dc.description.abstractВ статье изложены результаты экспериментальных исследований транспортирования семян по вращающимся семяпроводам, при которых обеспечивается качественное выполнение технологического процесса посева пропашных культур на скоростях движения посевного агрегата до 13, 26 км/ч. У статті викладені результати експериментальних досліджень транспортування насіння по обертовим насінняпроводам, при яких забезпечується якісне виконання технологічного процесу посіву просапних культур на швидкостях руху посівного агрегату до 13, 26 км/год. One of the reasons leading to a violation of the normal functioning of the rotational-hole drill process is the large duration of the seed movement on the seed ducts. As the seed drill speed increases, there is an emission of seeds to the surface of the soil, due to the delay in the supply of seeds to the lobes. Therefore, in order to make a reasonable choice of the operating modes of the seeder and to properly manage them, it is necessary to have data on the regularities of the movement of seeds by seed lines. In order to verify the theoretical premises for the transportation of seeds, a series of experiments was carried out to determine the reliability of the basic provisions of the analytical model of seed movement by seed ducts. The experiments were conducted on a laboratory plant with the connection of a source of compressed air to it. The pressure in the pressure chamber of the sowing machine was determined and controlled by a liquid manometer. The air jet velocity corresponding to each of the controlled pressures was calculated from the dynamic pressure measured with the Prandtl tube. The experiments used standard seeds whose sailing coefficient did not exceed 0.1 m-1. A regressive model is obtained that characterizes the effect of air pressure and the angular velocity of the wheel (seeder speed) on the angle of ejection of seeds from the seed tube. At the same time, the following regularities have been experimentally confirmed: large air pressure is required for the drill to work at high speeds. For operation at speeds of 2.00...3.60 m/s (7.0...13.26 km/h), the air pressure is required to be 1.00 ... 3.00 kPa. The unevenness of dispersion of the ejection angles in experiments was revealed. With the increase in the angular velocity of the wheel and the decrease in the air pressure, the dissection angle of the ejection increases markedly, reaching the magnitude unacceptable for practice at extreme levels. It is shown that the limiting dispersion characterizing the dispersion of the ejection angle of seeds can be expressed in numbers 7 ... 8. The regression equation is used to determine the seed rate at the outlet, depending on the air pressure and the circumferential velocity of the wheel, which satisfies the requirements of the seed processor process, the seed rate at the outlet does not exceed 7 m/s, which is less than the rate causing the seed trauma.uk_UA
