“…The displacement of the soil by the inclined plane of the wedge, located in the orthogonal section of the COD at an angle ε to the horizon, occurs at a certain angle ψ 1 (Fig. 3) [34][35][36]. In conditions of blocked cutting, the shear area is determined by the following expression…”

Subsoils are widely used on tillage and combination machines. The tiller of the combined machine for preparing the soil for sowing melons and gourds carries out strip loosening of the subsoil layers. The study aims to theoretically determine the traction resistance of a soil deepener of a combined machine for preparing the soil for sowing melons and gourds. The study uses the basic provisions of mathematics, theoretical mechanics, and agricultural mechanics. In studies, it is assumed that the destruction of the soil under the influence of the drill bit occurs by separation. The total traction resistance of the subsoiler was determined as the sum of the resistance of the rack and the bit. An analytical expression has been obtained to determine the traction resistance of a tilting machine with an inclined stand, depending on its design, technological parameters, and the physical and mechanical properties of the soil. As a result of theoretical studies, it was found that the traction resistance of the soil deepener is mainly influenced by its design parameters, the depth of soil cultivation, the physical and mechanical properties of the soil, and the speed of the machine.

“…The working process of the designed unit for implementing the proposed technology is as follows: subsoiler 4 with a tilt leg loosens the soil at the sides of the right ridge, the existing row spacing and deep linear loosening of the bottom layer of the right side of the ridge being formed, its blade 6 cutting the top layer of soil turns it to the left -to the right of the middle of the existing ridge, and ripper 3 loosens the bottom part of the top layer of the right ridge [33][34]. Then deep loosener 5 with tilt stand loosens the soil on the sides of the left ridge of the existing row, and deep linear loosening of the bottom layer on the left side of the ridge being formed, its blade 7 cutting off the top layer of soil turns it to the right -to the left side of the middle of the existing ridge, and loosener 3 loosens the bottom part of the top layer of the left ridge.…”

The study aims to justify the design scheme and main parameters of the combined aggregate for soil preparation for cotton sowing on ridges. The authors have developed the technology of soil preparation for cotton sowing on ridges and the aggregate for its implementation. The technology and design scheme of the developed aggregate are presented. The unit consists of a mouldboard deep loosener with a sloping rack and a ridge maker. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. The optimum constructive scheme of combined aggregate is grounded. It was established that to provide formation of new ridges instead of existing ones on fields without stems of cotton with the required degree with minimum power consumption working surfaces of inclined deep looseners equipped with mouldboards and rippers should be turned to each other and shifted relative to each other in a longitudinal plane. The formation of ridges to the required degree with minimal energy input is ensured at a width and length of the subsoiler's chisel, respectively 5 and 20 cm, the width of the wing width 21 cm, wing length between 47 and 49 cm, minimum longitudinal spacing between subsoilers 35 cm.

“…The machines and tools created as a result of these studies are used with certain positive results in the tillage of the slopes. However, these studies have not sufficiently studied the issues of substantiating the parameters of the disk working bodies of rippers that form ridges on the surface of the field to protect the soil from water erosion and ensure high quality of work with minimal energy costs [38][39]. The purpose of the study is to substantiate the parameters of a spherical disk working body.…”

The purpose of the study is to substantiate the parameters of a spherical disk working body. New technology of tillage of slope fields that prevent water erosion, a design scheme of a ripper for its implementation is presented. The ripper consists of lower and upper working bodies of the “paraglider” type and a spherical disk. The study applied the laws and rules of theoretical mechanics, agricultural mechanics, mathematical statistics, and methods of strain measurement and the methods given in the existing regulatory documents (TSt 63.04.2001, TSt 63.03.2001). The new technology of tillage of slope fields makes it possible to form step ridges on the surface of the arable land and on the bottom of the furrow, which protects the soil of the slopes from water erosion. It is established that when the diameter of the spherical disk of 510 mm, the curvature radius of 56 mm, tilt angle relative to the direction of motion of 28-30° to the vertical at an angle of 17-18°, the transverse and longitudinal distance between the disc and work on the bottom ripper respectively 30 and 20 cm ensures the formation of ridges on the surface of the field according to agrotechnical requirements at a minimum cost of energy.
