        <p>The article presents data on the theoretical study of the forces acting on seeds moving inside the working element of a shelling device with a spherical element attached to the inner surface of the drum, as well as their movement around the spherical element. The results of theoretical studies showed that the seed reaches its maximum flight distance when sin 2α=1, i.e., α= (π/4). Therefore, several seed layers struck by a spherical element are also forced to rotate at a certain angle after touching them. Since the spherical elements are arranged in a chess-like shape, after hitting the first spherical element, the seeds make a circular movement, hit the next one, spin again, and so on. This leads to efficient and complete sowing of seeds, as well as a reduction in the time required for the technological process.</p>

        <p>В статье приведены сведения о результатах теоретического исследования сил, действующих на семена, движущиеся внутри сферического элемента, закрепленного на внутренней поверхности барабана дражирующего устройства, а также их движения вокруг сферического элемента. Результаты теоретических исследований показали, что максимальное значение дальности полета семян достигается при sin 2α=1, т.е. α= (π/4). Поэтому несколько слоев семян, ударившихся о сферический элемент, после соприкосновения с ними вынуждены совершать вращательное движение под определенным углом. Поскольку сферические элементы расположены в шахматной форме, семена после удара о первый сферический элемент совершают вращательное движение, ударяются о следующий, снова вращаются и так далее. Это приводит к эффективному и полному перемешиванию семян и сокращению времени, затрачиваемого на технологический процесс.</p>

        <p>Maqolada qobiqlash qurilmasining barabanini ichki sirtiga sferik element mahkamlanib, uning ichida harakatlanayotgan urug‘larga ta‘sir etadigan kuchlar hamda ularni sferik element atrofidagi harakatini nazariy tadqiq etish natijalari to‘g‘risidagi ma‘lumotlar keltirilgan. Nazariy tadqiqotlarning natijasi shuni ko‘rsatdiki, urug‘ uchish masofasining maksimal qiymatini sin 2α=1, ya‘ni α=(π/4) ga teng bo‘lganda zabt etadi. Shuning uchun sferik elementga kelib urilgan bir nechta urug‘ qatlami ham ularga tekkandan keyin, ma‘lum burchak ostida aylanma harakatlanishga majbur bo‘ladi. Sferik elementlar shaxmat shaklida joylashganligi sababli, urug‘lar birinchi sferik elementga urilgandan ktyin aylanma harakat qilib, keyingisiga uriladi va yana aylanadi va haqazo takrorlanadi. Bu holat urug‘larni samarali va to‘liq bulanishi hamda texnologik jarayonga ketadigan vaqtni qisqarishiga olib keladi.</p>
