Abstract: Розроблено математичну модель однозернового висіву насіння дисковим комірчастим апаратом, який встановлено вертикально. Представлено розрахункову схему для визначення сили виштовхування зернин з висівного апарата й наведено аналітичні залежності для визначення складових сил виштовхування, сил тертя, обертового моменту, а також швидкість виштовхування зернин з висівного апарата визначено за формулою згідно з планом швидкостей.
Cereals, spikes and industrial crops play an important role in the structure of the crop sector of Ukraine supplying population with the foodstuff and industry with primary products. Wide use of high productivity variants of drain crops and organs of grain crops, introduction of the efficient and resource-saving cultivation is very important at the stage of setting up the agricultural sector. For the last seven years in Ukraine the average gross grain harvest equaled 29.2 million tons with the total demand of 40 - 45 million tons. Therefore, at the current stage of the national agricultural reform reestablishment the varying use of high productivity sorts of crops and the introduction of intensive and energy-saving technologies of their cultivation is very important. The dynamic model of single-seeding by the vertically installed disk cell machine is proposed. The essence of the design is that in the middle of the outer cylindrical part of the removable ring for different seed sizes being replaced while changing the sowing seeds, in the radial direction the ring groove, the depth of which being equal to or greater than the maximum size of grain, is made. The seeds interact with the pushing surface of the wedge mounted rigidly in the stationary body with the possibility of being relatively replaced. The sharp ring of the wedge is set under the cell disk at the angle towards the direction of the disk rotation, its position being adjusted. The essential feature of the sell disk is the fact that on the external diameter of the basis the external removable ring is set rigidly, which is changed dependently on the size of the sowing material seeds. The calculation scheme for finding the seeds pushing power from the sowing machine is developed. The analytical dependences for finding the pushing forces components: friction forces, torque are presented as well as seed pushing speed from the sowing machine is found according to the formula of the speeds plan. The analytical dependence for finding the productivity of the seeding machine and the seeder in general is proposed. Taking advantage of the precise single-seeding the method will make possible to decrease more than in two times the sowing seeds portion and to increase the productivity by 10 - 15% due to the creation of the efficient conditions of the plants feeding during the sprouting and growing.
