JUSTIFICATION OF THE MAIN STRUCTURAL AND TECHNOLOGICAL PARAMETERS OF THE EMBEDDING PART OF THE SEEDER FOR SOWING GRASS

Abstract

The constructive and technological parameters of the embedding part of the seeder for sowing grass based on the analysis of the coulters of existing seeders for sowing grass and based on the identified shortcomings in the technological process of coulters are substantiated and proposed in the given article.Constructive parameters of the disc coulter: disc diameter 350 mm; angle between disks α=100; the position of the vanishing point of the disks β=400 and the angle of the coulter leashes γ=320. The theoretical dependence of the traction resistance of the disc coulter on its constructive and technological parameters and the physical and mechanical properties of the soil has been obtained. From the power analysis of the mechanism of the embedding part of the planter for sowing grass, the following was established: the dependence of the forces acting on the disk coulter and the press wheel on the depth of seed placement, as well as the magnitude of the force that provides a given depth of seed placement.
