Dynamics of the movement of the ripping tool for surface tillage

The study aims to analyze the stability of the movement of the ripper tool for surface tillage. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. The dynamics of the movement of a ripper tool for surface tillage are considered, depending on the forces acting on it and its design parameters. A computational dynamic model is developed, and an equation describing the angular oscillations of the longitudinal links of the parallelogram ripper mechanism is obtained. It is established that the uniformity of the depth of the cultivator depends on the amplitude and frequency changes of the components of the disturbing force, physical and mechanical properties of the soil, the moment of inertia of the Ripper, the length of the longitudinal links parallelogram mechanism, the forces of the pre-tension pressure springs, and its stiffness. It is established that the required uniformity of the depth of tillage can be achieved by selecting the pre-tension force of the pressure spring and its rigidity. Theoretical and experimental studies have established that the required uniformity of the processing depth with minimal energy consumption of the soil is provided with a pre-tension force of the pressure spring of the ripper attachment mechanism of 350 n, spring stiffness of 40 n / cm, and a speed of 2.0 m/s

Cultivation of plants based on new technologies in the dry soil of the Aral Sea

The article presents the results of research aimed at growing plants on the basis of different technologies in the relic-swamp salt-sand desert soils of the Aral Sea. The amount of annual precipitation on the soils of this area formed in the conditions of the arid climate region is 180-200 mm. Many factors should be taken into account for growing plants in these areas. It is necessary to choose a suitable halophyte plant for marshy saline soils and to take into consideration sharp changes in temperature throughout the season. Planting in these soils is due to atmospheric precipitation and groundwater. Therefore, experiments were carried out on plant cultivation in the pipe method, and the efficiency was up to 1.5 times higher than in conventional conditions. The combined use of different technologies with the pipeline method has further increased efficiency
