Deformation of the Ribs and Crumpling of the Cross-section of the Soil Layer during Its Turnover into Its Own Furrow

The soil layer undergoes complex deformations during its turnover, which cause its crumpling and collapse. The identification of the pattern and level of deformations of the soil layer during its turnover makes it possible to design plough surfaces with the most rational structural and technological parameters. A promising method of soil treatment, which provides a cohesive leveled surface of arable land, is to turn the soil layer by 180°C into its own furrow. The technology of plowing with the turnover of a soil layer into its own furrow makes it possible to destroy the layer along the lines of the least soil connections. The purpose of this study is to quantify the deformation changes of the soil layer during its turnover into its own furrow. Deformations of the ribs and crumpling of the cross-section of the soil layer are studied depending on its parameters and the intensity of twisting during turnover. The amount of crumpling of a soil layer has been estimated depending on its dimensional characteristics. Theoretical and experimental studies of the turnover of the soil layer into its own furrow have made it possible to detect new deformation phenomena that are generated during its purposeful displacement and establish patterns of influence of the geometrical parameters of the layer on the deformation of the ribs and crumpling of the cross section. The optimization of the soil layer parameters makes it possible to select an option when the soil will collapse mainly under the influence of tensile deformations, which is beneficial from an energy point of view.
