Development of a vibratory working organ of a subsoiler

The article considers the design of a vibrating working body of a subsoiler, developed for a method of tillage that improves energy and agrotechnical performance. Deep loosening of the soil allows to improve the quality of tillage. Based on the results of the analysis of the working bodies of the tools and methods for reducing the traction resistance of deep diggers (according to the type of working body, the layout of the working bodies on the frame of the tool, the use of vibration of the working bodies), a design solution is proposed that will significantly reduce the traction resistance of the soil to the working body, - the use of vibration in the proposed design using vibrators, which will allow, including It is necessary to reduce energy costs when performing basic tillage. The study of the properties of cultivated soils using vibration made it possible to substantiate, in accordance with the purpose set in the work, a constructive scheme for transmitting vibration to the working body of a tillage. A mathematical model is proposed for determining the traction resistance of a deep loader, which allows calculating the magnitude of the forces acting on the rack of the working body, as well as on a component of its design - a vibrating chisel. The refinement of the traction resistance of the chisel by the resulting centrifugal force of inertia of its rotating element (eccentric) makes it possible to assess the degree of vibration of the working body on the soil. When determining the parameters of the mathematical model, the values of the parameters of the working bodies of deep-diggers and chisels in the conditions of stony soils of the Southern Urals were used. For the calculated scheme of the working body, its design parameters were determined, and a significant decrease in the traction resistance of the chisel gun using a vibrating chisel was obtained. An experimental study of the designed and manufactured prototype of a working organ with a vibrating chisel, conducted in laboratory conditions in accordance with an updated methodology, confirmed the calculated data on reducing traction resistance and improving agrotechnical soil parameters.
