Investigation of various options for processing gray forest soil in a field crop rotation

The paper presents the results of studies of various variants of the main treatment of gray forest soil in the experimental field in JSC “Lednevo” of the Yuriev-Polsky district of the Vladimir region Russian Federation. The experiment includes 12 strips, with an average area of 7.5 ha, consisting of 3 variants, with decreasing intensity of tillage and 4 repetitions. Based on the studies, it was found that the main problem associated with the physical condition of the soil was significant compaction of the soil at a depth of 20 – 25 cm. When using dump processing, increased soil heterogeneity was observed, and with “minimal” variants, the presence of weed vegetation was noted, which required changes in the strategy of using plant protection products and strict compliance with crop rotation. In this paper, it is recommended to remove the “plow sole” and reduce soil compaction by deep loosening of the soil to a depth of 35-40 cm in autumn, followed by a transition to a minimum soil treatment by cultivators

Green Technologies for Management on Railroad Transportation

Technique and technology development allows us to discuss the possibility of crucial changes into a conservative way of railroad transportation management. One of the options regarding the train control system is aimed at denial of the classic approach being connected with the implementation of a traditional automation kit. The authors of this article are being presented with the conception of a green IT railroad rolling stock control system called Green Interlocking. The above approach helps us rely on effective inexhaustible energy sources and modern know-how of data processing plus important technologies management

Technology of hardening surfaces of working bodies by electromechanical processing

The article presents the results of research on technology development and substantiation of the modes of strengthening the working surfaces of earth-moving machines by the electromechanical method. The types of wear and the appearance of defects on the working surfaces of the part are analyzed, taking into account the operating conditions. Based on the conducted studies on the study of surface wear, the arithmetic mean values were determined using the example of a plowshare of a bulldozer blade. A technology for restoring a part with subsequent electromechanical hardening has been developed. The influence of processing modes on the surface hardness was studied, and using a multifactorial experiment, a regression equation was identified, and optimal hardening modes were substantiated

Determination of the dependence of the humidification circuit parameters during drip irrigation on the properties of irrigation water

To ensure the optimal water-air balance of the plant, agro-reclamation measures are required, including the organization of irrigation. The advantage of drip irrigation is the most rational consumption of irrigation water. To realize this advantage, it is necessary to calculate the irrigation rate taking into account the dynamics of moisture distribution in the soil. During irrigation, the humidification circuit takes on a semi-elliptical shape. To determine the geometrical parameters of the humidification circuit, one should take into account the physical and mechanical properties of the soil and irrigation water, the mineralization of which varies widely. Having identified the numerical dependences and the nature of the distribution of moisture in the soil and having calculated the parameters of the irrigation circuit, it is necessary to determine the flow rate per dripper and subsequently calculate the irrigation rate, taking into account all of the above factors. The proposed method for calculating the irrigation contour will make it possible to rationally use water for irrigation, minimizing losses due to filtration into deep soil layers. Optimizing the water regime of plants during the growing season will not only save water and energy resources, but also maintain an optimal water and air regime, which will increase the yield and improve the quality of grown products

Scientific bases of control of vibration of hydrodynamic origin in centrifugal pumps

The reliability and efficiency of pumps, like any machines and mechanisms, is determined by a number of factors, including their operating conditions and the ability to adapt to changing operating conditions. This article is devoted to the development of scientific foundations for controlling vibration of hydrodynamic origin in centrifugal pumps. The failure of a centrifugal pump due to fatigue failure of a rolling bearing does not occur suddenly and not instantly. First, some signs of the approach of this process appear, the nature of the vibroactivity of the aggregate changes. Against the background of a stable vibration level, some vibration outliers appear. The study of the sequence and intensity of these emissions is important information not only about the approach of the moment of destruction of the rolling bearing parts, but also about the operating time that the operating personnel still have to take measures to eliminate an emergency and complete catastrophic destruction

Geoinformation systems and technologies in agriculture logistics and transport

The article contains theoretical considerations on the application of information technology in the field of logistics and transport. In the process of performing mechanized work during construction or in land reclamation measures, technical and technical means are used to provide fuel and lubricants. Based on the analysis of modern information technologies are recommended that ensure a reduction in material and technical resources and an increase in the utilization rate of machines over time
