At the same time, the analysis of the works showed that the action of the inertia forces of plants when moving in curved pulling channels is not analyzed, their effect on the quality of the technological process is not found, the condition for pulling all plants from the soil without their excessive flattening, which reduces their effectiveness, is not determined.</p> <p><bold>OBJECTIVE:</bold><italic> </italic>Theoretical and experimental study of the process of pulling flax plants with devices with transverse belt-disc channels.</p> <p><bold>METHODS:</bold> Experimental studies were carried out according to well-known and developed methods, with an assessment of flax products according to the GOST standards. The influence of the centrifugal inertia forces of plants on the bending of the plant belt, stretching of its upper part and loss of flax balls, and the condition of pulling all plants, taking into account the maximal strength of the tearing resistance of plants, were determined. Standard equipment and developed installations were used.</p> <p><bold>RESULTS:</bold> Dependences were obtained for determining the inertia forces of plants in the zones of pulling pulleys and deflecting rollers, and bending moments created by the inertia forces of plants and acting on plants, as well as the speed of the pulling belt, to prevent greater inertia forces of plants, negatively affecting the quality of work, and the condition of pulling all plants from the soil with taking into account the maximal strength of the stretching resistance. The limit value of the bending angle of the plant belt, which should not exceed 20°, has been found experimentally.</p> <p><bold>CONCLUSIONS:</bold> When designing flax milling machines with belt-disc channels to reduce the inertia forces, it is necessary that the elements of adjacent milling sections have the same size and shape as possible, which will reduce the forces of inertia of plants, eliminate peak pressures in a channel, increase the durability of the belt, reduce losses of flax products.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Механизированное теребление посевов осуществляется наиболее эффективными льнотеребильными аппаратами с поперечными ленточно-дисковыми ручьями. Вместе с тем анализ работ показал, что в них не проведён анализ действия сил инерции растений при перемещении в криволинейных теребильных ручьях, не установлено их влияние на качество выполнения технологического процесса, не определено условие теребления всех растений из почвы без их чрезмерного расплющивания, что снижает их эффективность.</p> <p><bold>Цель работы</bold> — теоретическое и экспериментальное исследование процесса теребления растений льна-долгунца аппаратами с поперечными ленточно-дисковыми ручьями.</p> <p><bold>Материалы и методы.</bold> Экспериментальные исследования проводили по известным и разработанным методикам, с оценкой льнопродукции по ГОСТам. Определялись влияние центробежных сил инерции растений на отгиб ленты растений, растяжение её верхней части и потери семенных коробочек, и условие теребления всех растений с учетом максимальной силы сопротивления растений тереблению. Применялась стандартная аппаратура и разработанные установки.</p> <p><bold>Результаты исследования.</bold> Получены зависимости для определения сил инерции растений в зонах теребильных шкивов и отклоняющих роликов, и изгибающих моментов, создаваемых силами инерции растений и действующих на растения, а также скорости теребильного ремня, для предотвращения больших сил инерции растений, отрицательно влияющих на показатели качества работы, и условие теребления всех растений из почвы с учетом максимальной силы сопротивления растений вытягиванию. Экспериментально установлено предельное значение угла отгиба ленты растений, которое не должно превышать 20°.</p> <p><bold>Заключение.</bold> При проектировании льнотеребильных аппаратов с ленточно-дисковыми ручьями для снижения сил инерции необходимо чтобы элементы смежных теребильных секций по возможности имели одинаковые размеры и форму, что позволит уменьшить силы инерции растений, исключить пиковые давления в ручье, увеличить долговечность ремня, снизить потери льнопродукции.</p></trans-abstract><kwd-group xml:lang="en"><kwd>flax plants</kwd><kwd>plant belt</kwd><kwd>flax balls</kwd><kwd>velocity</kwd><kwd>inertia force</kwd><kwd>acceleration</kwd><kwd>moment</kwd><kwd>bending angle</kwd><kwd>tension force</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>растения льна-долгунца</kwd><kwd>лента растений</kwd><kwd>семенные коробочки</kwd><kwd>скорость</kwd><kwd>сила инерции</kwd><kwd>ускорение</kwd><kwd>момент</kwd><kwd>угол отгиба</kwd><kwd>сила натяжения</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования РФ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of Russian Federation</institution></institution-wrap></funding-source><award-id>075-00899-22-01</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Novikov EV, Basova NV, Bezbabchenko AV.
