The paper proposes a new method for multistage plowing that implies loosening bottom soil and subsoil horizon simultaneously, followed by overturning the bottom soil without cutting, which improves the quality of soil cultivation, softens a plow sole and reduces energy costs. Experimental studies confirmed the theoretical relationship for determining the plowing resistance, both of certain working bodies of a section, and of a whole plow. The method proposed for multistage plowing that implies loosening the subsoil provides a decrease in plowing resistance by 8.3-9.8% compared to the existing double-depth plowing followed by loosening the subsoil.

The research objective is to improve the quality of soil loosening using combined working bodies for surface moisture-retaining soil cultivation. The efficiency of accumulation and conservation of precipitation in the autumn-winter period depends on the method of post-harvest soil cultivation. One of them is the autumn surface water-retaining treatment, which makes it possible to increase the efficiency of the processes of accumulation and conservation of moisture due to the deeper loosening of the cultivated soil layer. During loosening and mulching, the top layer of the soil contributes to the accumulation and preservation of moisture not only in the upper but also in deeper soil horizons. However, the used tillage tools do not fully solve the problem of the high-quality performance of surface moisture-retaining soil cultivation. The article presents the results of studies of the degree of influence of geometric and technological parameters of the additional active cultivator on the quality of surface tillage. Based on the results of the research carried out, the technological process of performing the surface tillage operation has been improved and combined working bodies have been developed for its implementation.

Abstract The article is devoted to the assessment of the comparative experimental studies’ results of various technologies for drying impregnated insulation of power electrical equipment in the process of manufacturing and repair: standard technology, which provides for convective drying using high-power electric ovens, and the proposed technology and methods for accelerated drying in hardware complexes using infrared (IR) radiation. In particular, the article presents the results of the polymer insulation surface microstructure analysis after drying by the indicated methods. The research was carried out in an industrial environment, using specialized certified equipment. In theoretical terms, the article presents the calculations on the rationale for the use of IR radiation during drying of a multilayer insulating structure of various compositions. The studies carried out confirm the hypothesis about the formation of microcavities on the surface and in the thickness of the polymer insulation when using convection during drying, which reduce the quality and reliability of the electrical equipment insulation as a whole. At the same time, the proposed technology and technique for accelerated drying of electrical equipment insulation using IR-radiation gives an opportunity to improve the quality of the resulting polymer insulation, increasing its reliability. In addition, this technology can significantly increase the productivity of insulation repair and reduce energy costs.

Studies of many authors show that injury of seeds has a negative effect, both on seeds and food grains. Damage in food grains reduces its trade, technological and baking performances. The main reasons causing injury to the seed, is mechanical action of the working bodies of machines and implements for post-harvest treatment of seeds. In this injury will be greater, the greater the speed of the seeds moving. Analysis of the distribution of injury between the individual elements of the line revealed that about 50 % of all injury of grain (28.3 %) falls on transporting machines. From above it follows that a reduction of injury to the seeds is an important problem, which is caused by the need to solve large yield losses, worsening of seeds storage and decrease in quality of the seed, and it is necessary firstly to investigate the possibility of improving the quality of conveying machines, and in particular , bucket elevators. This is because grain cleaning machines provide improved cleaning quality of grain, and conveying ones- conversely increase its. Taking into account that in cleaning lines usually there are several elevators, the reduction of seed damage by them will substantially improve the quality of the processed material. For this purpose, it is necessary to improve bucket elevators, providing softer mode. In this regard, the work was done to improve the design of the upper head of the elevator to reduce feedback eruption. On this construction patent for utility model number ZA 140052 was received. On the basis of this patent bucket elevator was refitted, in which head was an additional horizontal belt conveyor. Experimental studies have been conducted to identify the degree of feedback. It was found that an additional belt conveyor helps to reduce feedback rash when its speed is higher than the speed of bucket belt.

Theoretical calculations and experimental studies show that during the technological process of transporting seeds by technical means, in particular ladle conveyors, macro- and especially microtrauma of grains occurs, which affects a decrease in quality indicators. Analysis of the studies shows that the structural parameters of the working bodies, the biological and physico-mechanical properties of the kernels, as well as the material for the manufacture or coating of the working elements, affect the trauma and quality of the seeds. Experimental data showed that microtrauma of winter wheat grains before transportation was in the range of 22,9- 23,5%, and after completion of the transportation process was 45,3-46,4%, that is, doubled. Further studies to improve the quality of seeds of grain crops, reduce the harmful effects of microorganisms on caryopsis and reduce macro- and microtrauma should be carried out in the relationship and the complex of biological and physico-mechanical features of the entire technological process.

Currently, the machines are energy-intensive and inefficient, since the tools are mounted on tractors with a creeper reducer, and the cutters have to work in the conditions of the sodden upper soil layers, which significantly reduces the quality and productivity of the process. This served as an impetus for the creation of new technical tools that would combine the best qualities of plows and milling tools, expand the range of possible applications, but at the same time were devoid of their shortcomings. So there appeared tools with combined working bodies, for example, a strip thrower, developed on the basis of the G.F. Morozova. However, these developments also do not completely solve the problems of the efficiency and quality of preventive and forest fire operations, since the working bodies of milling, although working on a loose soil-soil shaft, are still not protected from roots and stumps, they have a large mass and dimensions due to a combination of two types working bodies in one design. A comparative analysis of technical means and experimental studies of a prototype forest fire soil-throwing machine with a combined working body was carried out.
