Разработали решетчатый рыхлящий рабочий орган, улучшающий сепарирующие способности элеватора копателя.</p><p>(Цель исследования) Обосновать параметры решетчатого рыхлителя копателя моркови, который обеспечивает интенсивное разрыхление почвы и увеличивает полноту сепарации примесей при минимальном повреждении корнеплодов.</p><p>(Материалы и методы) Исследовали геометрические, кинематические параметры решетчатого рыхлителя копателя моркови. Изучив физико-механические свойства грядки моркови, теоретически обосновали конструктивные параметры механизма и его кинематические показатели.</p><p>(Результаты и обсуждение) Установили, что при взаимодействии решетчатого рыхлителя с почвенными пластами на элеваторе происходит разрушение почвенных комков, разрыхление почвы при следующих параметрах: радиус рыхлителя – не более 9,5 сантиметра, высота расположения вала – 20 сантиметров, погруженная часть лопасти рыхлителя – 6 сантиметров, ширина решетчатого рыхлителя – 47 сантиметров.</p><p>(Выводы) Выявили, что решетчатые рыхлители способствуют интенсивному сепарированию почвенного пласта без повреждения и потерь корнеплодов моркови. Доказали, что окружная скорость решетчатого рыхлителя должна быть не более 2,5 метра в секунду, кинематический режим средства интенсификации сепарации – 2,5, радиус рыхлителя – не более 9,5 сантиметра.</p></abstract><trans-abstract xml:lang="en"><p>The authors showed that during carrot harvesting by diggers, strong soil lumps were formed that were poorly separated from root crops and complicated the separation process, which leaded to machines overloading, due to the variability of the physical and mechanical soil properties. A lattice loosening working body was developed that improved the digger elevator separating ability.</p><p>(Research purpose) To substantiate lattice ripper parameters of the carrot digger, which provides intensive loosening of the soil and thereby increases the impurities separation completeness with minimal root crops damage.</p><p>(Materials and methods) The authors researched geometric, kinematic parameters of lattice ripper of the carrot digger. They theoretically substantiated the design parameters of the mechanism and its kinematic parameters after they studied the physicomechanical properties of the carrot bed.</p><p>(Results and discussion) The authors found that during the interaction of the lattice ripper with soil layers on the elevator, soil lumps were destroyed, the soil was loosened with the following parameters: the ripper radius was not more than 9.5 centimeters, the height of the shaft was 20 centimeters, the blade submerged part was 6 centimeters, the width of the lattice ripper was 47 centimeters.</p><p>(Conclusions) It was revealed that lattice ripper promoted intensive separation of the soil layer without damage and loss of carrot root crops. The authors proved that the peripheral speed of the lattice ripper should be no more than 2.5 meters per second, the kinematic mode of the separation intensification means should be 2.5, and the radius of the ripper should be no more than 9.5 centimeters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>копатель моркови</kwd><kwd>сепарация почвенных комков</kwd><kwd>решетчатый рыхлитель</kwd><kwd>клубненосный пласт</kwd><kwd>морковь</kwd><kwd>кинематический режим</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carrot digger</kwd><kwd>soil lump separation</kwd><kwd>lattice ripper</kwd><kwd>tuberous layer</kwd><kwd>carrot</kwd><kwd>kinematic mode</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Норчаев Д., Норчаев Р.
