A MODERN APPROACH TO POTATO PRODUCTION

abstract 1281704008 issue 128 pp. 146 – 153 28.04.2017 ru 133
Potato has been and remains one of the five world's most important crops. For nearly two hundred years potato in Russia is the "second bread". This is one of the so-called social products. Over the past 20 - 25 years of potato farming in our country, there have been significant changes, both positive and negative. Today, potatoes are grown in different soil and climatic conditions in more than one hundred countries around the world, including the desert oasis and beyond the polar circle. Potato cultivation Center recently has moved to Asia. In our time, the leaders of potato production are China, Russia, India, the US and Ukraine. Over the past few decades the number of produced potatoes has increased by 41% and the area under potato planting only 9.5%. From the above data it is clear that the world potato economy in recent years has got significant changes, indicating that the timeliness and relevance of the material in this article is true

ANALYSIS OF METHODS OF DIAGNOSING OF FUEL EQUIPMENT FOR AUTOTRACTOR DIESEL ENGINES AND THE DEVELOPMENT OF A MATHEMATICAL MODEL OF A HIGHPRESSURE FUEL PUMP

abstract 1231609010 issue 123 pp. 169 – 192 30.11.2016 ru 329
In agriculture the issue of enhancing the efficiency of operation of internal combustion engines (ICE), reducing the costs of maintenance (TO) and repairing (TP) fuel supply apparatus (TA) using the improvement of methods and means of diagnosis is a topical in connection with the aging rolling stock farming and lack of investment. Analysis of the known TA diesel engine vehicles systems showed that the most widespread system is the divided type with multiplunger high pressure fuel pump (fuel pump), while the methods of its diagnosing are laborious, they require partial disassembly and have insufficient accuracy. The mathematical models that characterize the work of a high-pressure fuel pump (fuel pump) use a large number of parameters that significantly affect the quality of dynamics of the change of pressure values of diesel fuel. However, in the materials of previously published articles there were no issues considered assessing the extent of the quantitative impact, performance and features change in the sensitivity settings of the mathematical models on the simulation results, there are no recommendations on the degree of sensitivity and importance of each of the parameters. For a more accurate diagnosis of the fuel supply apparatus of a diesel engine it is advisable to use several methods of diagnosing. The article substantiates development of a mathematical model of a high-pressure fuel pump based on the analysis of modern methods of diagnosing of fuel equipment for autotractor diesel engines

FEATURES OF THE APPLICATION OF MODERN TRACTOR TRANSPORT IN THE TECHNOLOGICAL PROCESSES FOR THE CULTIVATION OF AGRICULTURAL CROPS

abstract 1261702013 issue 126 pp. 180 – 198 28.02.2017 ru 171
The role of transport in agricultural production is significant. It is the connecting link in the technological chain of the agro-industrial complex (of the APC). On-farm transport in the APC together with cars and tractor transport are widely used. The rationality of the use of wheeled tractors for farm transport substantiates the possibility of their movement on asphalt and on dirt roads. The specific gravity of the tractor transport in the domestic agriculture is 22-27% of the total volume of transport and 50-60% of the volume of farm traffic. A high level of use of tractor transport has been observed in the countries of Western Europe and the USA. In the farms of leading countries of Western Europe (Germany, Italy, France, etc.) about 70- 90% on-farm transport of agricultural goods is done by tractor transport. Tractor transport in a live environment is running on roads with varying terrain, a wavy profile cover, on soils with different hardness and humidity. When driving vehicles at high speeds, the trailer is wobbling from side to side, constantly accompanying tractor transport during its operation. As a result, it is bad for propulsion, transmission, and it deteriorates the dynamic performance properties of equipment, working conditions of the operator. To reduce the amplitude of oscillations of the trailer, the operator is forced to work strenuously with the steering wheel or to slow down the speed, which in turn affects operator fatigue, as well as the performance and maneuverability of the vehicle. Thus, advanced technologies in electronics, sensor technology and software will determine the nature of agro-technical innovations and will lead to increased automation of business processes in crop production with the aim to organize the work more effectively, efficiently, accurately, environmentally friendly and economically feasible. When working with intelligent technologies, understanding the development of high-tech, precision engineering requires a revision to the personnel policy and education in agriculture, which should be based on the relevant organization of farms and their proper new type engineering solutions

IMPROVING THE RELIABILITY AND DURABILITY OF THE DEVICE FOR REMOVING THE TOPS WITH CAREFUL TREATMENT OF POTATO TUBERS IN HARVESTING MACHINES

abstract 1191605061 issue 119 pp. 834 – 864 31.05.2016 ru 177
Due to the deterioration of the ecological situation in the world, population tends to eat organically grown foods that are grown either without or with minimal use of chemicals. The development of agriculture in this direction leads ultimately to organic agriculture. To improve the competitiveness of this direction, we need more effective agricultural machines, especially in the last phase of cultivation, namely at the stage of harvesting. One of the most difficult scientific and technical problems with the mechanical harvesting of potatoes is not letting vegetable impurities and tops to fall down in the hopper with the potato tubers, which among other things will improve operational efficiency technology. The article reviewed the various methods for removing the tops, as well as their advantages and disadvantages. The article makes a conclusion about the need for potato top separators in harvesting machines. We have also considered a promising device for removing haulm, a conveyor with flexible fingers on the bars and the clamping beater. Тhe most short-lived structural element of the device for removing haulm, reducing reliability of the device, is flexible fingers mounted on rods. We have proposed to use polyurethane as a material for manufacturing flexible fingers

METHODS OF DIAGNOSIS STUDY FOR NUMBER OF STATIONS FOR INTERACTIVE MONITORING THE TECHNICAL CONDITION OF MACHINERY IN AGRICULTURE

abstract 1281704011 issue 128 pp. 188 – 199 28.04.2017 ru 105
Condition monitoring is a necessary element of the transport and special machinery in agriculture. The task of the control operations other than the determination of the technical state of the object is to determine the required amount of work, as well as rational amount of collateral the repair of which could be combined with the next maintenance. Based on the results of processing of the information, we may generate requests for service. In the conditions of uncertainty of receipt of requests for servicing of individual machines, estimated volumes and timing, we have am appropriate development of applied technique of justification of the number of diagnostic posts for interactive control of a technical condition of vehicles and special machinery in agriculture. The presented methodology is based on probabilistic methods, and allows the quick optimization of the number of existing posts interactive diagnostics in the enterprise, if necessary, translating the existing posts in "standby" mode, or Vice versa, returning from a reserve in "work" mode. The production and technical base of the enterprise service based on the specific assumptions are considered as a system of mass service (SMO), and the function of such a SMO – as the process of mass service. The process of queuing as applied to interactive diagnosis are "Markov" processes "death and reproduction" with a finite or countable number of States and continuous time. To describe the states of the system we use the system of the Kolmogorov equations for steady state of "Markov" process. On their basis, we have determined average queue length, time of stay orders in the queue, number of busy channels and the bandwidth of the CFR. Using the intensity of the requests and the service time of a single application for specific equipment, the article establishes the efficiency of online diagnosis posts. The result of the proposed applied methodology enables timely decision-making about the need for reconstruction or technical re-equipment of the company
