DETERMINATION OF FORCES AND DRIVING RESISTANCE TO THE INTRODUCTION OF DISC SHEETS OF THE SEEDING SECTION INTO THE SOIL

Abstract

The article is devoted to the determination of the rational parameters of the experimental model of the sowing section of a grain fertilizer seeder, the operation of which in a given mode depends on the possible action of resistance forces that prevent both the penetration of seed discs to a certain depth into the soil and its movement along the stubble in compliance with the sowing technology. In this case, the sowing technology implies the performance of all sowing operations, such as cutting plant residues on the soil, cutting weeds at the sowing depth, sowing two rows of seeds, applying a primary dose of mineral fertilizers below and between them, and finally rolling the furrows cut by the discs in one pass of the seeder.

Тhe article presents the results of both theoretical and empirical methods of research, which are based on the world experience of modernization and intensification of means of mechanization of grain sowing with simultaneous application of fertilizers to the soil. The theoretical results presented in the article are based on the proven and previously known variables of soil mechanics, on the methods of furrow formation, as well as on the rules and dependencies that make it possible to stabilize the stability of the sowing section model in both the vertical and horizontal planes, the use of which should lead to a minimum the cost of measures for the modernization and intensification of ongoing activities.

The starting hypothesis of the studies and their results is the minimization of changes in both the dynamics and kinematics of the sowing unit model, including the design and power supply of the main units, the operation of which should increase the productivity of the entire sowing complex, reduce overall operating costs while maintaining sowing technology.

The article schematically shows changes in the design of the well-known grain-fertilizer sowing section, the implementation of which will provide the technology for performing all the necessary sowing operations in one pass of the section model - with loosening the developed soil with sowing discs, ensuring the sowing of seeds by each of the sowing discs, applying primary fertilizer at a given depth, rolling loose soil over the furrows.

The presented analytical results are confirmed by experiments and compared with the known data of independent world scientific sources that are in the public domain.
