05.20.00 Processes and machines of agroengineering systems
DescriptionNew ways of solving reducing soil compaction problem are substantiated. Soil compaction destroys its structure, violates its water-air regime, and leads to erosion and reduced yield. The effectiveness of the presented directions, based on the analysis of the issue and the results of own research is confirmed by practical use in the crop production processes mechanization of intellectual engineering authors' developments, based on their inventions and well-known serial technology selected from Automated reference system "agricultural machinery". It was the synthesis of own research results and modern agricultural machinery best samples analysis that allowed us to form an effective system of machines that reduce the harmful soil compaction. This ensures soil fertility preservation and crop yield increase. The set of machines proposed in the system for soil processing, sowing, fertilizing, spraying and harvesting not only reduces soil compaction but also improves work quality, labor productivity and complexity of the work performed, harvest and reduces costs of all types (energy, money, labor). The basis of the problem solution consists of a combination of technological operations for one pass of the unit across the field, multifunctional units application in the system that performs tillage and seeding, fertilization and tillage, additional fertilizing of spike crops with simultaneous harrowing, harvesting with simultaneous stubbling or straw pressing etc., refusal to use heavy machinery in the fields, trucks, conversion tracked system on tractors, front and rear hydraulics for making multi-functional units, the use of fundamentally new machines and adaptations to them according to the inventions of the authors

DEVICE FOR PRE-SAMPLE PROCESSING OF SOIL
05.20.00 Processes and machines of agroengineering systems
DescriptionThe considerable share in prime cost of products of agricultural production is made, now, by power expenses. It promotes that the considerable attention is given power - both resource-saving to the equipment and technologies. Thus, the modern science is faced by a global task – creation of cars and tools of new generation, high-economic, highly productive, less power-intensive and metal-consuming. One of the most power-intensive processes of production of agricultural production is processing of the soil. In this article on the basis of numerous researches use of rotary motion of the soil-cultivating working body allowing to improve a design of tillage machines, to reduce metal consumption, power consumption, to increase quality of work is offered. In this article, we offer the device for preseeding processing of the soil on a frame of which the working bodies in the form of flat disks with sharpening working in the horizontal plane, but with the accounting of an angle of deepening of working body are in chessboard order established. Rotary motion which promotes fuller cutting of rhizomes of weed plants and to improvement of quality of preseeding processing of the soil is forcibly transferred to working bodies. Justification of the offered device, constructive and technological schemes of the tool, conclusions and offers are given in the article

DescriptionDue to the disconnectedness of production processes, prevention of soil degradation and plant diseases, as well as the difficult establishment of functional dependencies between the parameters of the working bodies and the physicomechanical properties of the soil, the richness of foreign technology, there is the problem of creating innovative structural and technological solutions for basic soil tillage including for the purpose of import substitution. To solve it, KubGAU has developed: “Multifunctional plow” (patent of the Russian Federation No. 2618342); “Plow with rotary bar” (utility model RF patent No. 184196); “Multifunctional plow with a rotary bruce” (positive decision on the patent application of the Russian Federation). Formal models, schemes and descriptions are given

PRODUCTION TECHNOLOGY OF PREPARATION OF SOIL BY TERRACING THE SLOPES
05.20.00 Processes and machines of agroengineering systems
DescriptionSlope land (ravines, gullies, mountain areas) for many countries of the world are important areas of economic activity, and for some they are the only living space. In the mountainous areas there are cereals and feed, fruit, citrus, nut, berry and essential oil crops, grapes, tea and many others. On slope lands, soil preparation by terracing is widely used. The article considers modern technologies and machines for the construction of terraces in order to create protective and fruit plantations on them and to involve new areas in agricultural turnover. There are two main ways to create terraces: hinged and rifled. Most often, when terracing on tractor-passable slopes, various plows and graders (floor terraces) are used, and on tractor-passable slopes there are universal bulldozers and terrasers (rifled terraces). The shuttle plow PCHS-4-35 and revolving plows are especially convenient for the device of floor terraces, with the help of which it is possible to significantly increase labor productivity by reducing the time for idle runs. For rifled terraces, we use a large complex of machines, the most productive of which are: terraser-Ripper TR-2A; terraced equipment TK-4; terraser T-4M, etc. The use of the proposed complex of machines in the construction of raised and rifled terraces will help to increase productivity and involve new lands in agricultural turnover, which will ultimately increase food security of the Russian Federation

05.20.00 Processes and machines of agroengineering systems
DescriptionTransplanting seedling into the field is an extremely important period for all seedling crops, as the plant passes through basic vegetation stages. After carried analysis of seedling transplantation machines utilization it became obvious that they all have low technical and exploitation parameters. The purpose of the research was elaboration of theoretical bases for calculating parameters of a unit for seedling feeding to transplanting device, which implementation will lead to increase efficiency of transplanting. The article presents the results of theoretical researches for proving parameters of a unit for seedling feeding to transplanting device. A system of equations for acting at seedling forces during its transportation from collecting drum to feeding drum is arranged. We have also calculated nomograms for defining drum rotating frequency depending on seedling friction coefficient on surfaces of collecting and feeding drums. Parameters of pneumatic feeding drum were technologically proved. Its principle is equality of capacities of feeding unit and transplanting device. We have elaborated a nomogram for defining feeding drum rotating frequency depending on plant spacing and velocity of transplanting machine

THEORETICAL JUSTIFICATION OF CONSTRUCTIVE AND REGIME PARAMETERS OF THE ARABLE AND MILLING UNIT
05.20.00 Processes and machines of agroengineering systems
DescriptionPre-planting preparation of soil in the Central part of the North Caucasus according to the traditional technology of cultivation of crops involves the use of single-operation soil processing machines and aggregates. As a result, they have to make multiple passes, resulting in increased energy consumption, soil compaction, and the emergence and development of erosion processes. In addition, the agricultural machinery used is characterized by the low operability and reliability of the working elements and their joint assemblies, which leads to a decrease in productivity, so that the agricultural requirements for the process of pre-sowing soil preparation are often not met. In order to solve the above-mentioned problems, an arable milling unit for pre-sowing soil preparation is proposed. Its structural and technological scheme is justified. The distinctive features of the proposed design are the possibility of the main soil treatment with simultaneous grinding of large soil clumps, lumps, plant residues and levelling of the soil surface; possibility of changing the installation angle of the rotary grinder and depth of soil treatment depending on the type of treated soil; high quality of soil preparation for sowing; provision of energy consumption reduction due to combination of technological operations in preparation of soils for sowing; lack of expensive assemblies and parts; the need for less energy for aggregation when preparing soils for sowing. As a result of the theoretical studies carried out, rational values of the main parameters of the proposed arable milling unit have been established, which have a decisive influence on the process of its operation: speed of movement 1.5... 2.0 m/s; Angle of attack of working element 20... 300; Angular rotation speed of the working tool 20... 25 s-1
