The working process of sowing seeds of small-seeded oil crop imposes a number of strict requirements on the designs of sowing machines and the parameters of their operation. Currently, many agricultural enterprises prefer mechanical sowing machines. Among them, roller devices have become particularly widespread. The main advantages of these designs include low cost, simplicity, and reliability. However, they are also not without drawbacks. When working with seeding roller units, the following problems arise: uneven distribution of seeds along the length of the row, instability of the total seeding of seeds, injury of seeds. To eliminate the above disadvantages, designers and scientists improve designs of the seeding roller units. In this regard, the paper considers the process of developing a 3D model of seeding roller unit for sowing seeds of small-seeded oil crop in the Compass-3D graphical editor by parameterization method. A technology for setting a three-dimensional model of a seeding roller unit has been developed. Theoretical studies have been conducted to determine the optimal design and operating parameters of the seeding roller unit, and their results are presented. 2D and 3D models of the main and auxiliary original pieces of the seeding roller unit were built, general view of the seeding roller unit, a 3D assembly of the seeding roller unit was created. The main and auxiliary original pieces of the experimental seeding roller unit were manufactured on a 3D printer, and the seeding roller unit was assembled. Laboratory studies of the physical model of the experimental seeding roller unit have been carried out, and the results are presented.
