Deformation of the ribs and crumpling of the soil layer cross-section during its rotation in its own furrow

In the process of its turnover, the soil layer undergoes complex deformations, under the influence of which it crumples and collapses. The identification of the nature and magnitude of deformations of the soil layer during turnover allows the design of plough surfaces with the most rational structural and technological parameters. A promising method of soil treatment, providing a cohesive leveled surface of arable land, is to wrap the soil layer by 180 °C into its own furrow. The technology of plowing with the turnover of the formation into its own furrow makes it possible to ensure the destruction of the formation along the lines of the least soil connections. The purpose of the work is to quantify the deformation changes of the soil layer during its rotation in its own furrow. Deformations of the ribs and crumpling of the cross-section of the formation are studied depending on its parameters and the intensity of twisting during rotation. The amount of crumpling of the soil layer has been estimated depending on its dimensional characteristics. Theoretical and experimental studies of the turnover of the soil stratum into its own furrow have made it possible to detect new deformation phenomena that occur during its purposeful movement and to establish patterns of influence of the geometric parameters of the stratum on the deformation of the ribs and the crumpling of the cross section. As a result of optimizing the formation parameters, it is 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.
