OPTIMIZATION AND MODERNIZATION OF DAIRY FARMS’ TECHNOLOGICAL PROCESSES

Abstract. The paper presents the results of research on the optimization of dairy farms and  modernization of production processes. The economic efficiency of construction and operation  of dairy farms of various capacities is determined. The comparative effectiveness of using  various technical means in performing technological operations on dairy farms is given, and  recommendations for production are given. According to a number of foreign and domestic  scientists, the economic efficiency of agricultural enterprises depends on many factors. The  most determining factor in milk production is the capacity of dairy farms and complexes.  In European countries, the farming system has determined the size of dairy farms of 20–100  cows. There are 800–2000 cows or more in the USA and Canada. In Russia, due to the large  territories and the lack of well-maintained access roads and roads, the construction of farms  and complexes of high capacity is not rational. The computer program developed by the authors  makes it possible to determine the optimal size of dairy farms for various regions of Russia.

Key words: optimization, dairy farm, productivity, cost, profitability, modernization of  production.

IMPROVING THE EFFICIENCY OF PORK PRODUCTION BASED ON THE USE OF INNOVATIVE TECHNOLOGY

Abstract. Analysis of pig farming in the country has shown that the industry is developing along  the path of consolidation, integration, concentration, specialization, and the creation of large  industrial associations based on pig enterprises. The main constraining problems affecting the  growth of the industry's efficiency are identified. Calculations of the number of pigs in Russia (at  the end of the year) were made. The production of pigs for slaughter was analyzed. Calculation  of production of pigs for slaughter is carried out. Recommended machines and equipment for  different age and gender groups. Technological indicators achieved in Russia and their forecast  for 2030 in accordance with the strategy for the development of mechanization and automation  of animal husbandry for the period up to 2030 are considered. A comparison of technological indicators of pork production in Russia and in foreign countries is made. Studies have shown  that the most effective pork production facilities are those that produce their own feed, fattening,  slaughtering, processing pork and selling their products. Suggestions for further development of  pig breeding in Russia are given.

Key words: agro-industrial complex, animal husbandry, pig breeding, technology, efficiency,  innovative equipment, modernization, digital technologies.

THE RESULTS OF LIVESTOCK PREMISES’ NITROGEN LOSSES RESEARCH

Abstract. A number of main technological and technical solutions that affect the reduction of  nitrogen losses in the form of ammonia in livestock facilities for keeping cattle and breeding pigs  are analyzed. Proposals are presented to reduce nitrogen losses, which will improve the state  of the environment, increase the efficiency of production and use of organic fertilizers. It was  found that the excess of nitrogen in feed contributes to an increase in the amount of nitrogen  entering the manure. Increasing the productivity of cows from 10 to 40 kg per day doubles the  nitrogen retention in the animal's body. The formation of a diet for each phase when fattening  pigs reduces nitrogen release by 21...25 %. Additives of the drug "Triyun" to liquid pig manure  reduce the concentration of ammonia in the air of the room up to seven times. The use of sloping  floors with a litter consumption of up to 0.1 kg per head per day, bioactive additives and rational  organization of pig dens halve ammonia emissions. The use of geothermal heat exchangers for ventilation of premises for keeping pigs helps to reduce ammonia emissions by at least 25 %.  Minimum nitrogen losses in the room with tethered cows-8.1 % are achieved when using screw  conveyors, with loose content, losses can be reduced to 16.8 % when using scraper installations  with step-by-step movement of the scraper.

Key words: nitrogen loss, ammonia emission, productivity, rations, indoor climate, technical  means of manure removal.

WAYS TO INCREASE THE PRODUCTIVITY OF A SINGLE BUCKET EXCAVATOR WITH  AN AUTOMATIC DIGGING PROCESS

Abstract. The features of the technological cycle of a single-bucket excavator with working  equipment "reverse shovel"are investigated. A certain problem is the limited visibility when  developing the ground below the level of the excavator Parking lot. Factors that affect the performance of the machine are noted. The norms of execution time for individual operations  are analyzed and the degree of influence of each factor on the duration of the technological cycle  is studied. It is established that optimization of the digging time, as the main component of the  technological cycle of soil development, will significantly increase the productivity of the machine.  The degree of influence of the human factor is noted: the qualification of the driver, the degree  of his fatigue, the duration of work on the duration of the operations under consideration. Ways  to optimize the technological cycle of work production are considered and recommendations  for its improvement are presented. The analysis made it possible to determine the parameters  for ensuring the bucket's filling capacity: the optimal values of the angle of penetration of the  working body into the ground and the chip thickness. The possibility of using automation tools  when performing individual technological operations is investigated, and ways to reduce the  time of individual operations when using automatic tools are analyzed. It is noted that the use  of automation will solve the problem of increasing the working cycle time during the shift due  to driver fatigue. Various methods of determining the distance to the face surface are analyzed  in order to ensure the specified values of the bucket depth angle in the ground and development  with a given chip thickness. The use of laser sensors to determine the depth of the bucket is  proposed, and the composition of the necessary equipment to ensure the performance of the  technological cycle under study in automatic mode is considered.

Key words: excavator working equipment, chip thickness, bucket parameters, excavator  operation cycle, range finder, digging process, working position, automatic mode.

DESIGN OF A MOBILE DITCH HYDRAULIC LIFT FOR REPAIR WORK

Abstract. The problem of repair, maintenance, diagnostics, storage and disposal of motor  vehicles remains urgent. All these actions are performed on special equipment designed for  specific technological operations for car repairs. A stable mode of car repair production  is provided by the coordinated and trouble-free operation of various lifting machines and  mechanisms (PM and M). The closest to the proposed technical problem and the achieved result  is a mobile hydraulic lift, containing a frame with wheels, foldable boom with sharnirno-linkage  and upper and lower sections, connected with the reference node, and the actuator vertical  movement of the foldable boom having a hydraulic cylinder associated with the lower section  of the boom pivotally connected at one end to the frame, and a flexible rod, fixed at one end to the upper boom section and the other end is fixed to the frame. However, the well-known mobile  hydraulic lift does not have the ability to accurately bring the outer end of the upper section of  the boom to the place where the load is installed without additional maneuvering. The article  presents the principal removal of a mobile ditch hydraulic lift, designed for hanging over the  inspection ditch or lift front or rear axles of passenger cars, as well as individual units of the car.  Calculations of modes and strength calculations of individual parts are carried out.

Key words: car, hydraulic lift, carriage, rolling stock, layout, structural safety.

THE RESULTS OF EXPERIMENTAL STUDIES OF THE WEAR RESISTANCE  OF THE SURFACE OF THE CRANKSHAFT RESTORED BY THE METHOD  OF FLAME APPLICATION OF SELF-FLUXING POWDERS

Abstract. The development of the agro-industrial complex of the Russian Federation is one of  the strategic tasks of the country's security. An important place among the main directions of  solving this problem is to provide agriculture with high-quality equipment and maintain its  performance throughout the entire period of operation. The implementation of these measures  is not least related to the organization of effective repair of worn-out machine parts. Crankshafts  are among the most expensive components that are subject to constant abrasive wear. Restoration  of the damaged surface layer of the shaft necks is performed by various methods. Gas-flame application of self-fluxing powders is a technically simple and cost-effective method that allows  not only to restore the part, but also to strengthen it. In this regard, an important aspect is the  optimal choice of powder, which allows you to get a restored layer with the required quality  characteristics. Restoration quality control is performed in accordance with the regulatory  standards that establish the procedure and methodology for testing. The article describes the  results of experimental studies of the wear resistance of the crankshaft surface restored by the  method of gas-flame deposition of self-fluxing powders. The results of actual experiments that  allow choosing the most wear-resistant material for restoring and strengthening the surface  layer of parts based on a comparative analysis are presented.

Key words: wear resistance, friction testing, flame deposition, self-fluxing powders, restoration  of agricultural machinery parts.

THЕ STUDY TRIBOTЕСHNIKA PROPЕRTIЕS OF BIODIЕSЕL BASЕD ON RAPЕSЕЕD OIL

Abstract. Questions of tribological properties of biodiesel based on rapeseed oil are considered.  The methods presented in the article are universal and allow optimizing the ratio of biodiesel  components. Compliance with the requirements of modern international environmental standards for diesel fuel leads to the need to add components of plant origin. One of the most  suitable components of biodiesel is rapeseed oil. The practice of using highly refined fuels in a  number of countries in Western Europe and the United States shows that reducing the content  of harmful substances in exhaust gases is accompanied by premature failure of precision pairs  of fuel supply equipment, including plunger pairs of high-pressure fuel pumps. Previously, it was  found that biodiesel is superior to diesel in terms of environmental parameters, and rapeseed oil  is one of the cheapest of all vegetable oils produced. The use of biodiesel based on rapeseed poses  new challenges for manufacturers of automotive equipment, as it requires studying its impact  on fuel equipment. In the course of research, the tribological properties of biodiesel fuel were  studied using the ISO 12156-1:1997 method on a high-frequency reciprocating device (HFRR).  Biodiesel fuel with different rapeseed content was studied and its tribological characteristics  were determined.

Key words: mixed fuel, biodiesel, biofuel quality indicators, rapeseed oil, low-temperature  properties.

METHODS FOR CREATING A DATABASE OF CAR RECYCLING TECHNOLOGIES

Abstract. A lot of attention is paid to the prospects of industrial vehicle recycling in the Russian  Federation, but to date this has not led to any progress in the formation of a network of recycling  enterprises. This is due not only to the lack of legislative, regulatory and methodological support  for approaches to the formation of the network, but also to the lack of a regulatory framework  for technologies for recycling complete cars and their elements. Based on the analysis of design  factors that characterize the controllability, accessibility, ease of removal, interchangeability,  unification and transportability of the recycling facility, methods were identified that allow developing approaches to the organization and technological support of recycling processes  for both complete objects and their components. Analytical, graphoanalytical, experimental computational, and complex methods should be considered as methods that allow determining  the potential labor intensity of disposal and establishing the most rational technology for  recycling an object. These methods are characterized by different levels of applicability in the  current conditions of recycling enterprises, this is primarily due to the limited data on rational  methods of disposal and the limited criteria selected for evaluating this level. The article analyzes  the methods and selects the most rational ones for today's conditions, which allow creating  economically justified technologies for car recycling, which will allow determining the potential  labor intensity of disposal of decommissioned equipment and the required resources for the  formation of the production and technical base of recycling enterprises.

Key words: decommissioned car, car recycling, recycling technology, recycling processability  of the car, recycling suitability, level of utilization, production and technical base of recycling  enterprises.

DIGITAL SYSTEMS INTEGRATION INTO AGRICULTURE WITHIN THE RECLAIMED LANDS

Abstract. The scale and success of measures to create, implement and use innovative digital  methods of "smart" agriculture in the practice of everyday economic activity is due to the success  of their operation in agricultural production that meets the requirements of environmental  and economic sustainability of the domestic and foreign agro-industrial complex. Changes  in methods and methods for creating and using automated production process management  systems (APCS) and General approaches to managing enterprises and organizations (APCS)  currently determine the increased relevance of research to ensure the success of automating  the regulation of the reclamation regime of agroecosystems, focused on the evolving regime  of irrigated land. Research on the strategic development of domestic innovations, conceptual  provisions of the country's industrial evolution, forecasts of scientific and technical development  of the Russian agro – industrial complex, data from Russian priority production platforms,  scientific publications on the problems of innovative development of agricultural production,  digitalization of the economy, and the work of specialists OF the A. N. Kostyakov VNIIGIM were  used as the substantiating material for the results. The purpose of this work is to form priority  areas in the field of "digital irrigation", providing the creation of innovative management  systems for irrigated agricultural production. The analysis of the effectiveness of using digital  methods that regulate the operations of irrigated crop production has shown a significant gap  between domestic products and the best foreign samples and the need to improve them based  on the development of cloud products, the widespread use of large data array technologies, the  creation of software complexes with elements of artificial intelligence, the use of neural networks,  and so on. The requirements for the functional structure and architecture of modern automated  production process management systems focused on monitoring and accounting for the  reclamation state of agroecosystems, intelligent data processing, the formation of management  solutions and their implementation automatically without human intervention are defined.

Key words: digital systems, agricultural production, irrigation, crop production, requirements,  functions, structure, architecture.

THE ROLE OF RECLAIMED LAND IN DIFFUSE POLLUTION OF WATERS WITH NUTRIENTS

Abstract. The paper presents a methodological approach and results of assessments of the impact of reclaimed land on diffuse pollution of water bodies in the Volga river basin. The upper Volga basin is characterized by the development of drainage reclamation of agricultural land, and irrigation reclamation is widely used in the Middle and Lower Volga. Calculations based on the use of meteorological data and empirical dependencies on the formation of drainage runoff and removal of nutrients from drained agricultural lands of the Upper Volga showed that in the average long-term section, 1564.44 million m3 of drainage water can enter water bodies. The average annual removal of nitrogen is 4.67 thousand tons, phosphorus-0.16 thousand tons, potassium-3.25 thousand tons. An estimated calculation of the volume of drainage runoff and salt removal from irrigated lands to water bodies of the Middle and Lower Volga basin showed that the volume of drainage runoff in modern conditions is approximately 225.9 million m3 , which is 22 % of the water intake; in the future, the volume of drainage water may increase to 557.12 million m3 ; the volume of mineral salt removal is determined at 430.16 thousand tons per year.

Key words: diffusion pollution, water body, irrigation, drainage, drainage runoff, surface runoff, biogenic substances.

FACTORS AFFECTING THE QUALITY OF TEA LEAVES

Abstract. The current state of production and consumption of black baich tea is considered. The factors affecting the quality of this product are considered, as well as the production and consumption of tea per capita are analyzed. It is established that the possibilities for sustainable tea production in the Krasnodar region are not limited, since there are prerequisites for favorable soil and climatic conditions for this crop. The article notes the production of high-quality black baich tea as the main final product of production, which is possible only from raw materials of the required quality. This raw material is a tea leaf, the quality of which is determined by the calendar dates, the frequency of collection and the corresponding number of tender leaves on flushes. High – quality tea can be obtained mainly from two-and three-leaf flushes. It is known that the average annual consumption of tea per capita in different countries varies in a wide range from 540 to 3450 g. Since tea plantations develop successfully only in tropical and subtropical climates, tea production is limited to a limited number of countries. In Russia, tea plantations are located only in the Krasnodar territory. In order to take advantage of the current favorable conditions for the restoration and further production of tea in the Krasnodar territory, it is necessary to take appropriate in-depth scientific and subsequent production measures.

Key words: tea, tea quality, tea production, tea selection, soil and climate conditions, agrotechnical measures.

RISING THE RELIABILITY OF DISTRIBUTION RURAL ELECTRIC NETWORKS

Abstract. The analysis of the level of reliability and ways to improve it was carried out, reliability indicators were selected based on the methods of power grid organizations, and a mathematical model was formed that will allow the most qualitative determination of the volume of maintenance and repair work (Maintenance and Repair). Equipment failures that occur cause great economic losses from under-supply of electric energy and damage to consumers. The most "worn-out" electric networks with a voltage of 6-10 kV are most susceptible to failures. The considered methods of increasing reliability in the process of operation of rural distribution electric networks have shown that the most important thing is to increase the reliability of each element of the electric network during operation. The existing system of scheduled preventive repairs (PPR) does not take into account the actual state of the elements during repairs, but only focuses on the time of commissioning. The selected reliability indicators - indexes of importance, unreliability, and technical condition – allow us to more fully assess the real level of reliability of a single element of the electrical network based on diagnostic and analytical work. The formulated mathematical model will allow electric grid organizations to plan work on Maintenance and Repair, which will lead to the repair of elements of electric networks that need it, thereby most effectively and efficiently apply the PPR system. The results of the study make it possible to use a mathematical model in creating a neural network for medium-and short-term forecasting of Maintenance and Repair operations, which will increase the level of reliability of electric networks and reduce economic losses.

Key words: electrical network, failures, reliability indicators, maintenance and repair

USE OF SIMILARITY THEORY METHODS IN THE ANALYSIS AND CALCULATION OF SHORT-CIRCUIT CURRENTS

Abstract. Investigation and calculation of emergency processes occurring in electric power systems is an integral element of system design and operation. All changes related to its development and improvement of the equipment used require a detailed analysis, assessment of changes in operating modes, and development of recommendations for managing the scheme in normal and emergency modes. The calculation of short-circuit currents is most often used in the analysis of emergency modes. An important point in this situation is to determine the possibility of applying certain calculation methods related to the characteristics of the equipment of the electric network and electricity consumers. The most effective methods are the methods of similarity theory. Analysis of the physical and mathematical similarity of objects allows you to apply fairly simple and effective practical methods for calculating the parameters of emergency processes, without resorting to fairly complex mathematical calculations. One of these practical techniques is the method of relative units and the method of typical curves and the method of rectified characteristics constructed using it. But this approach is not possible in all cases. Individual elements of the electrical network, such as direct current inserts, high-power consumers with frequency conversion of electricity, which are now being used, do not always meet the requirements of physical similarity, which can lead to significant errors in calculations. The result of the research is to determine the possibilities of using various calculation methods for analyzing emergency processes.

Key words: short-circuit currents, theory of similarity and modeling, system of relative units, physical and mathematical similarity.
