One of the most significant technological problems of repeated basic tillage of agricultural soils is the formation of a plow sole at a depth that is characteristic of basic tillage. The most commonly used method of eliminating the plow sole is its mechanical processing, which in practice is implemented by a wide range of soil tillage machines of various designs. Applied tools for mechanical destruction of the plow sole have a number of disadvantages not structural but also agrotechnological in nature. To remedy these shortcomings, it is proposed to use a "soil absorber" in the form of a semi-loop flexible thread, which is secured to the two pillars of the first and last plow housings for main plowing. In order to substantiate and develop the theoretical foundations of the balanced mechanical motion of the loop of the flexible working body in the bulk viscous-plastic medium of the soil and to determine its geometric and structural parameters, analytical studies of the mechanics of flexible filament moving in the separated volume of the bulk viscous plastic body were performed. environment. According to the determined results of analytical studies, the dependences can be calculated normal stresses in cross sections of a real flexible working body, from which the optimal values of the cross-sectional area are calculated taking into account the abrasive properties of the material of the structure and in accordance with the designated (selected) resource of work of flexible soil. The results of these analytical studies allow us to determine the design structural and geometric parameters of flexible soil tillage machines that are compatible and can be combined with a wide range of soil tillage tools for basic shelf and shelfless soil cultivation. |
