Existing technologies and modern technical means do not always provide the required quality of technological processes of growing crops. The growing demands in a competitive market environment necessitate the constant improvement of existing and the creation of new high-performance machines and machine units to ensure the quality of technological processes in precision farming systems.
The article presents improved theoretical principles of practical applied direction of agricultural materials MOVEMENT in air and liquid environments under the action of gravitational field.
As a result of research using a fundamental analytical and mathematical apparatus, an algorithmic model has been developed that describes the movement of: seeds or mineral fertilizers on the way from seed drills to furrows, which are formed in the soil after the passage of seed drill openers; grain that moves from top to bottom in the cleaning systems of combine harvesters or during unloading from the hopper, etc. Such processes and phenomena occur during the production operation of seeders and planters, machines for post-harvest processing of grain, harvesting of roots, fruits, berries, etc.
Particular attention is paid to the fall of raindrops or drops created by irrigation systems. The influence of the impact of drops on the field surface is analyzed, which provides the development of practical recommendations for the prevention of soil erosion, which is especially relevant in fields with difficult terrain. Some technical systems of creating "artificial rain" are considered, their technological schemes are substantiated and constructive and technological parameters are optimized.
The application of the algorithm of mathematical analysis and calculation of technological processes and technical systems provides the necessary conditions for seed germination, growth and development of crops in both plain fields and on sloping lands. In addition, the proposed innovative methods of theoretical analysis and calculation of processes and phenomena characteristic of agro-industrial production can be effectively and used in the educational process during the preparation of agricultural engineers for project professional activities.
