The purpose of the research is improvement of soil level processing quality by justification of key parameters of working bodies of the combined plow. The combined plow consisting of a frame and sections of working bodies is developed for realization of technological process of level processing of the soil with loosening of the subarable horizon. The working section supports the movements of the unit which are consistently established in the direction plow cases of the top tier with a ploughshare surface and the lower tier without ploughshare surface, containing a chisel and dump surface. For implementation of agrotechnical requirements to level processing of the soil the theoretical research on installation of depth of the course of cases of the top and lower tiers of the combined plow is conducted. The interrelation of bottom crests height of furrow from arrangement of working bodies in section and the angle of shift of the soil is investigated by chisel in the case of the lower tier. The distance between the case of the top tier and the case of the lower tier of the combined plow in the longitudinal plane for ensuring the free movement of the soil and stubble is proved. The carried-out theoretical justification and settlement and graphic determination of constructive parameters of working section cases of the combined plow are shown that their rational values are equal: width of capture of cases of the top and lower tier – 0.45 m; chisel width – 0.07 m; an interval of arrangement of working bodies on a plow – 0.45 m; distance between the case of the top tier and the case of the lower tier of the combined level plow – 0.55 m; depth of the course of the case of the top tier – 0.06- 0.18 m; the layer height which is cut out by the case of the lower tier – 0.25-0.35 m; processing depth chisel – 0.06-0.08 m.

Increasing the efficiency of direct strip sowing of grass seeds by means of seeders with active furrow openers is possible when seed and fertilizer working bodies are removed from the zone of operation of disk milling cutters. A structural and technological scheme of the coulter group of the sod seeder for strip sowing is proposed, which consists of a milling furrow opener, fertilizer and seed coulters mounted on leashes in the form of torsion spring trailers, and a rolling roller. To ensure high quality multilevel sowing of grass seeds and granules of mineral fertilizers, it is necessary at the design stage to determine the length of the fertilizer coulter sides, which prevent premature shedding of soil from the furrow walls until the mineral fertilizer granules reach the bottom of the furrow, and the minimum allowable distance between the fertilizer and seed coulters, which allows to cover the granules of mineral fertilizers with soil completely while maintaining the compact design of the coulter group. In the course of theoretical research, mathematical dependences were obtained to determine the rational parameters and operating modes of the coulter group of the proposed design, which will ensure a minimum spread of mineral fertilizer granules over the depth of incorporation and a high stability of the soil layer thickness between mineral fertilizer granules and grass seeds. Rational parameters of the coulter group of the proposed design are determined for the range of operating speeds of the sod seeder for strip sowing: angle at the apex of the shank fertilizer coulter in the horizontal plane is 15-20º, the length of the fertilizer coulter sides is 0.040-0.045 m, the width of the fertilizer coulter bell is 0.02 m, minimum permissible distance between the fertilizer and seed coulters is 0.14-0.16 м.

Abstract The main parameter for determination of quality of MDF boardprocessing after milling is roughness of the surface. The well-known models of wood cutting are unsuitable for the assessment of this parameter, since they make it possible to draw only qualitative conclusions about the roughness, they do not allow calculating the numerical value. To calculate the roughness value, the model must take into account the structure of the material and the main parameters affecting the roughness. The purpose of this work is to substantiate the development of a computer model of the MDF structure and the process of its milling using the finite element method. The implementation of this approach will allow, according to the specified parameters of the cutter and modes of its operation, to determine the quality and energy indicators of the milling process from a theoretical point of view. As a result of the work carried out, a detailed theoretical justification for the development of a computer model of MDF structure and the process of its milling was given. Its implementation makes it possible to determine the quality and energy parameters of the milling process according to the specified parameters of the cutter and its operating modes.

The aim of the work is to substantiate the geometric parameters of the distributor, which are able to provide the maximum range of fertilizer particles in the subclavian space, based on the analysis of all factors affecting the material particles during their transportation to the surface of the distributor. The result of research is to achieve a uniform distribution of fertilizers on the width of the capture and, accordingly, on the area. It is known that the particles of material sent in accordance with the given trajectories in the pre-provided areas of the surface of the furrow formed by the working body, in contact with the soil are significantly redistributed and the meaning of the traditional approach to uniformity is completely lost. In addition, it is necessary to take into account that for placing fertilizers in the soil, in most cases, flat-cutting working bodies are used. For normal operation, in terms of deepening into the ground, they must be installed with a forward tilt at an angle of up to 3°. As a result, the bottom of the furrow, which they form, acquires a conical shape with a slope to the center. In this case, it becomes obvious that the material must be fed not evenly across the width of the working body, and most of it to be directed at a clearly defined distance in the direction perpendicular to its axis. The numerical value of this distance is determined by the nature of the redistribution of the granules as a result of contact with the soil. In the process of rolling the granules or particles to the center, the uniformity of distribution will be restored. In this case, it becomes obvious that the material must be fed not evenly across the width of the working body, and most of it to be directed at a clearly defined distance in the direction perpendicular to its axis. The numerical value of this distance is determined by the nature of the redistribution of the granules as a result of contact with the soil. In the process of rolling the granules or particles to the center, the uniformity of distribution will be restored. In this regard, there is a need to solve the problem of ensuring the maximum range of particles in the transverse direction using the simplest geometry of the distributor surface. In our opinion, such a surface can be a prism. In the article the results of theoretical research of process of portage and distributing of granules of mineral fertilizers are resulted after a reflection from the plane of reflection in sub paw space of trivial cutting of working organ. Geometrical parameters and corners of location of reflecting plane are grounded. The obtained dependences allow to reasonably establish geometrical parameters of the distributor which will provide the set range of flight of particles of material for working bodies of various width of capture and to reach desirable result taking into account laws of their redistribution at contact with soil.
