Justification of the Expediency and Parameters of the Anti-Erosion Element in the Working Tool of the Deep Soil Loosener

The development of a new working tool for deep soil loosening requires a comprehensive approach to determining its design parameters and operating modes, based on interrelated and harmonized dependencies. The design process must account not only for the geometry of the tool itself but also for the heterogeneous physical and mechanical properties of the soil environment. It is also essential to ensure stable operation and achieve the required quality of work and energy efficiency of the technological process. ( Research purpose ) The aim of this study is to develop an anti-erosion deep soil loosener capable of bringing soil clods to the surface. ( Materials and methods ) The newly designed working tool is designed for primary tillage and deep loosening of soil to depths exceeding 25 centimeters, without inverting the soil layer. During anti-erosion treatment, it simultaneously forms molelike channels. A schematic diagram is presented to illustrate the interaction between the working tool and the soil. ( Results and discussion ) The scientific novelty of the study lies in establishing dependencies that describe the relationship between the tool’s design parameters and its operating modes during its interaction with the soil. These dependencies form the basis for developing an engineering method for calculating the tool, which is implemented in the form of reinforced bars that interact with the soil surface. The study also substantiates the mechanism of soil layer displacement and identifies the potential disruption modes, including the formation of secondary fracture planes that occur during the upward movement of the soil layer. ( Conclusions ) The parameters and operating modes of the working tool of the new deep soil loosener have been determined. To initiate effective soil descent, the clearance between the bars should not exceed 50 millimeters. For optimal soil clod trajectory, the shape of the bars should follow a first-order brachistochrone curve (a cycloid). The bar length of the working tool ranges from 0 to 0.4 meters, depending on soil conditions and operational requirements.
