In the southern regions of Russia, the technology of cultivation of grain crops in the variant of partial sowing has been widely used. In this regard, it became necessary to create effective working bodies of a stubble cultivator that would have fundamentally new resource-saving ways of influencing the area under cultivating and meet the requirements of modern advanced technologies. The shapes of the working bodies surfaces of the cultivators were improved taking into account the mechanic-bionic approach. The main parameters of the toothed cutting surface were determined by the method of bionic comparisons, with a scarab beetle as a bionic prototype. Use of the serrated shape of the cutting edge is consistent with the bionic principle of multi-contact exposure and leads to the fact that the tops of the teeth become stress concentrators and, with a significantly smaller indentation force, cause soil destruction processes, which reduces the energy costs of cutting the soil layer. The optimal curvilinear shape of the working surface made in the form of a logarithmic spiral, is characterized by a constant value of the angle between the normal and the radius vector, and the value of this angle, equal to the angle of internal friction of the soil φ2, will ensure the sliding of the soil and plant residues with minimal energy consumption. The number (n = 4), height (h = 5...7 mm) and tooth placement step (S = 10...12 mm) of the bit tip of the stubble cultivator are analytically justified. The shape of the profile of the working surface of the stubble cultivator bit in the form of a logarithmic spiral with a variable angle of crumbling is proposed. The studies were conducted in the period from September to October 2018 in the soil channel of the research Laboratory of Bionic Agroengineering of the Department of Mechanization and Technical Service in Agro-Industrial Complex. They have shown the decrease in the traction resistance of the proposed working body of the stubble cultivator by 16.5% in comparison with the traction resistance of the serial sample.

The article presents the methods and results of bionic modeling in agricultural mechanics, which made it possible to substantiate the arrangement and parameters of the working bodies of the loosening compacting discs of tillage rollers adapted to the soil environment using the regularities of the arrangement of thorns on wide rings of the tail in the biological prototype of the girdle tail (Cordylidae). Based on the principle of multi-contact action of the teeth and toothed plates of the roller discs on the soil layer, the coefficient of the arrangement of the discs on the roller is equal to 0.22 ... 0.24, as well as the number of toothed plates and teeth on the working surface of the loosening compacting disc of the roller, which is in the range of 6 ... 12, which is consistent with the arrangement of spines along the circumference of the wide rings on the tail of the girdle. The results of experimental studies, confirming the decrease in the traction resistance of the proposed working bodies of the loosening compacting discs of tillage rollers for surface tillage are presented.

Abstract The article presents data on the influence of various types of spherical disks on the discarding of soil in the horizontal and vertical planes during its processing. These studies were conducted in order to optimize the selection of working bodies of disk tillage machines in terms of resistance and processing quality. Three types of disks were used in the comparative analysis. Two types of discs with cutouts and one solid spherical disc. On one type of disk, the cutouts are made in the form of circular arcs, and on the other-in the form of arcs of a logarithmic spiral. The conducted studies have shown that within the working surface of the disk, the trajectories of movement of soil particles under the influence of the three types of disks under study differ little from each other. Although it can be noted that the steeper rise of the trajectory in the vertical plane provides a solid disk, and the smallest rise of the trajectory - at the disk with cutouts in the form of a logarithmic spiral. In the horizontal plane, the longitudinal movement of the soil mass is less in disks with cutouts, especially in a disk with cutouts along the arc of a logarithmic spiral. As a result of these studies, it was revealed that the disk working bodies with cutouts on the cutting edge in the form of arcs of a logarithmic spiral showed the best quality and energy indicators.

Under the action of the working surface of the tillage unit, three mutually perpendicular stresses and corresponding deformations occur in the soil layer, which are characterized by different time functions. The finding of these functional relationships is the fundamental task of agricultural mechanics, with the help of which the process of soil crumbling with different physical and mechanical properties can be described in interaction with working bodies. The article presents an analysis of the results of studies of domestic and foreign scientists of the process of soil destruction in its interaction with working bodies. When considering the process of soil destruction from the point of view of stress theory, the Coulomb-Mohr theory of destruction is most often used. It is proposed to expand the consideration of the process of soil destruction by adding elements to the theory of strength that will describe the rate of change of the acting loads.

The development of energy and resource-saving methods and technologies for strengthening and restoring the working bodies of agricultural machinery will increase their abrasive wear resistance and durability by using materials from machine-building waste and reduce the cost by 10-30 percent without reducing operational characteristics. (Research purpose) The research purpose is in increasing the abrasive wear resistance and durability of cultivator legs by surfacing powder materials obtained by electroerosive dispersion from solid alloy waste by high-frequency currents. (Materials and methods) Authors obtained a powder for research on their own experimental installations of the CCP "Nano-Center" of electroerosive dispersion from waste of sintered hard alloys of the T15K6 brand. The microhardness of powders and coatings on microshifts was measured using the PMT-3 device, and the hardness of coatings with the KMT-1 microhardometer was measured using the Rockwell method according to GOST 9013-59. The microwave-40AV installation was used to assess the wear resistance of materials of working bodies of tillage machines. (Results and discussion) In the course of laboratory wear tests the relative wear resistance of samples hardened by high-frequency surfacing currents significantly exceeds the wear resistance of non-hardened samples made OF 65g steel, accepted as the reference standard. (Conclusions) Based on the results of experimental studies, the article proposes a new resource-saving technological process for strengthening the working bodies of agricultural machinery through the use of materials from machine-building waste, which allows increasing the abrasive wear resistance of working bodies by 1.5-2 times due to the use of tungsten-containing materials.

The paper is devoted to the analysis of the state of the equipment recycling system in Russia and the issues of improving the legislative framework that accompanies it. The role of state structures in solving the problems of forming a resource-saving ecooriented system for the disposal of decommissioned equipment is reflected. To analyze the work in the field of waste management, to reflect the state of the legislative framework for the existing system of recycling equipment in Russia and abroad, to make recommendations for its improvement. Problems with waste appear when, in the process of production and consumption of substances, objects (equipment), he/she becomes unnecessary for their owners, their owner tries to get rid of this object in the most accessible way. According to numerous information, the disposal of equipment in Russia is mainly carried out (black waste collectors), which control more than 60 % of the scrap of non-ferrous and ferrous metals, so the solution to the problem of creating an effective system for the disposal of equipment becomes not just relevant, but vital for our state. The scientific community in Russia is constantly conducting research on the creation and implementation of a system for the disposal of decommissioned equipment, so, for example, MADI scientists proposed a regional car recycling system for implementation, the scientists of the Federal State Budgetary Educational Institution FNAC VIM also developed a regional system for the disposal of agricultural recycling equipment. In order to quickly solve the problem of working out a general strategy for creating an effective system of recycling equipment in Russia, taking into account the revision of the legislative framework, it is advisable to "run-in" it at the industry level, for example, in the agroindustrial complex, with subsequent replication in other industries.

Relevance. The preservation, reproduction and rational use of agricultural soil fertility is the main condition for the stable development of the agro-industrial complex. Mechanical tillage systems, the use of mineral and microbiological fertilizers are one of the main links in adaptive landscape farming systems. In the conditions of a sharp decrease in the rates of fertilizer application, an increase in the imbalance of elements of mineral nutrition of plants observed in recent years in agroecosystems, the function of improving the regimes of chernozems, preserving their fertility is designed to perform resource-saving technologies of soil cultivation in combination with effective methods of using agrochemicals that combine environmental and economic feasibility.Methods. The experiments were laid in 2017–2019 on chernozem heavy loamy soils typical for most farms in the Ulyanovsk region. The object of the study is spring wheat, the variety Ulyanovskaya 100. The subject of the study is the methods of tillage, doses of mineral fertilizers, the biological product "BisolbiFit". The following technological methods of using the biological product were studied: seed treatment before sowing, non-root treatment of vegetating plants and a combination of these methods. The experiment was carried out on three backgrounds: N0P0K0 (control); 2) N30P30K30; 3) N60P60K60.Results. It was found that the best nitrification ability was possessed by variants with fine combback and comb-back with soil-deepening treatment, in which the weighted average content of nitrate nitrogen was 3.29–3.33 mg/100 g, which is 35–36%; 26–28%; 43–44% more than with fine, conventional non-dump and dump treatment respectively. Plowing improved the conditions of phosphorus and potassium nutrition of plants by 25–37% and 6–14% compared to other treatments. When N30P30K30 and N60 P60 K60 were applied to the soil, the content of nitrate nitrogen increased by 46 and 91%, phosphorus — by 0–14% and potassium — by 6 and 21% compared to the nonfertilized background. More effective in terms of the effect on the productivity of spring wheat were comb-shaped treatments, where the average yield was 2.89–2.94 t/ha, which exceeded the usual plowing by 0.19–0.24 t/ha. The greatest increase in yield was obtained when combining the methodsseed treatment + spraying of vegetative plants with the biological preparation "BisolbiFit". On an unfertilized background, the increase in grain yield was -0.71, on the background of N30P30K30 — 1.04, on the background of N60P60K60 — 1.56 t/ha.
