“…The calculations have demonstrated that farms with the ploughland area of 1000-1200 ha, crop rotation with sowing of various crops requires one tool for a tractor of draught class 3 with complete universalization, able to perform all types of primary and additional tilling and crop sowing using interchangeable working elements and modules. For average-sized farms with ploughland area of 7-10K ha, versatile tools are required for tractors of 3-5th draught class with interchangeable working elements for tilling (moldboard, non-moldboard, chisel), with interchangeable modules for tiling to the depth of 0.1-0.16 m and tilling and sowing machines with interchangeable modules for mulching, presowing tilling and sowing with different types of working elements to the depth of 0.06-0.1 m. Large agricultural holdings need single-operation combines for all technological operations performed by tractors of draught class 5-8 [4].…”

“…The study results obtained for different zones show that without regard to the afore mentioned factors of the crop rotation system accepted in the zone, the biggest crop capacity is ensured by the technology that includes primary cultivation in autumn, mulching, presowing cultivation and sowing in spring [1][2][3]. For every zone, according to weather and climate conditions, the methods of primary and presowing cultivation and sowing should correspond to different types of work tools and depth providing conditions for development and growth of soil and crops; also, accumulation and rational use of moisture should persist during the whole vegetation period [4][5][6]18]. Similar data were obtained by foreign researchers [10][11][12][13][14][15][16].…”

Annotation-The crop capacity in different soil and climatic zones depends on implemented technologies of tillage and sowing, crop rotation and type of work tools of the machinery complex. In every zone, main and additional tilling should be made with different work tool types and to different depth corresponding to the zone conditions. The tillage should also provide conditions for plant growth and development, as well as accumulation and rational usage of accumulated moisture during the whole vegetation period. The work demonstrates that tillage by foreign machinery not tailored to Russian conditions as compared to locally produced machines withers the soil away, reduces crop capacity and increases the base costs. In this connection, the team of researchers has elaborated a universal technology for soil treatment and types of work tools for machines to put it into life. Having said that, the type and dimensions of farms dictates the degree of universalization of newly created machines, so they should have replaceable working elements or interchangeable modules. The methods for determining the metal consumption for machines of different type, their draught resistance and performance of equipment were developed; the calculations are also presented. The study yields dependencies that allow establishing adequate velocities of equipment and operating width of tilling and sowing machines that ensure maximum performance of equipment with tractors having different draught class. The parameters of machines are used by the engineers of LLC Chelyabinsk Compressor Plant, LLC Varnaagromash and Yaroslavovich Production Company for designing and putting into production a complex of tillage and sowing machinery for tractors of draught class 1,4; 3; 5 and 6-7. The developed complex of machines performs all components of tillage technologies for specific working conditions and corresponds to functional specifications of agricultural machinery, environment protection, ergonomics and energy saving. Thus, the developed import-substitution technology and complex of machines enable increased crop capacity and reduced base cost of cultivated crops, which is the basis for liquidation of food dependence of Russia.

“…Both agricultural science and practice have accumulated a great number of experimental factors that are taken into account in the design of new technological processes and working bodies [1,2,4,5,11,14] Constant improvement of technologies, agricultural machinery construction, intensification of modes of its work with simultaneous improvement of quality of performance of working processes complicate methods of calculation of structure and parameters of machines at their design. At the same time, methods of experimental designing and testing of prototypes of agricultural machines in the real-life conditions are of the great importance.…”

Nowadays both agricultural science and practice possess a great amount of experimental data that should be taken into account during the process of development of new technological procedures and working tools. Consequently, the necessity of designing of technical processes appears in order to identify their effectiveness. That is why appliance of methods of synthesis of technological processes is of immediate interests. These methods of synthesis of technological processes should be based on the characteristics of tillage, seeding and production systems of the economy and latter should define the realization of projected technological processes. The design of technological processes is one of the complex problems with its characteristic feature -the lack of knowledge about the methods of designing, suitable for system and structural modeling and algorithmization of design processes. To overcome this incompleteness, a systematic approach is needed. The system approach underlines that specificity of complex objects lies in the nature of their constituent parts and elements as well as in their interrelationships. This article presents the design methodology that is based on the formulated fundamental assumptions and principles of the system including more specific statements, revealing the structure and content of the design operations, the synthesis of the solutions choice. The article also deals with the designed principles of technological compatibility and emergence suitability for system-structural analysis of complex technical means and technological processes, consisting of statements having a hierarchical structure, where the degree of the goals specification increases from level to level, and the approval of the last level determines the direction of the search for the optimal solution of the problem.

Южно-Уральский государственный аграрный университет, г. Троицк, Российская Федерация; 2 Южно-Уральский государственный университет (национальный исследовательский университет), г. Челябинск, Российская Федерация Реферат. Колебание тягового сопротивления лемешно-отвального плуга при смене условий работы можно уменьшить, усовершенствовав конструктивную схему орудия. (Цель исследования) Снизить или исключить изменения тягового сопротивления плуга при помощи автоматических регуляторов глубины вспашки, что позволит уменьшить энергозатраты агрегата и, следовательно, повысить его производительность. (Материалы и методы) Рассмотрели две группы лемешно-отвальных плугов, отличающихся способом соединения рамы с осью подвеса трактора. Изучили их достоинства и недостатки. Для определения рациональных конструктивных параметров плуга оценили влияние взаимного расположения рабочих органов (корпусов) на тяговое сопротивление и глубину обработки почвы, а также на изменение формы и поперечной площади почвенного пласта. (Результаты и обсуждение) Представили расчетные зависимости, по которым видно, что при увеличении угла постановки рабочего органа в поперечной плоскости происходит скачок тягового сопротивления, зависящий от величины перекрытия рабочих органов. Выявили зависимость тягового сопротивления от положения оси вращения плуга: чем меньше величина отклонения положения плуга от оси вращения, тем интенсивнее падает тяговое сопротивление. Проанализировали три схемы плугов на почве с удельным сопротивлением 0,8 килограмма на сантиметр квадратный и выбрали предпочтительную. Определили, что изменение тягового сопротивления на единицу изменения средней глубины вспашки составляет для плуга первой схемы 146 килограммов на сантиметр, для второй-128, для третьей-210 килограммов на сантиметр. (Выводы) Выявили, что наилучшая конструктивная схема-у полунавесного плуга, имеющего шарнирное соединение с трактором в поперечной плоскости и опорные колеса, установленные на поверхности поля. На испытаниях плуг с данной схемой показал высокую технологическую надежность, существенное увеличение производительности (при силовом регулировании до 10-11 процентов) без ухудшения условий труда тракториста и агротехнических показателей. Ключевые слова: почвообработка, конструктивная схема, лемешно-отвальный плуг, тяговое сопротивление, почвенный пласт.
