Justification of the parameters of the working body of the deep tiller for anti-erosion tillage

BACKGROUND: As the crop production is continuously being improved in the modern life support system of mankind with qualitative and quantitative yield, it is necessary to find a balance in the metal intensity of agricultural processes, since this undoubtedly has an important overall economic significance because obtaining stable and high-quality yield is necessary in the agricultural production system. A special place in this system is taken by basic tillage, both with and without seam turnover. To ensure the workflow of basic tillage for sowing, a new working body for basic non-fallow tillage was developed at the Donskoy Agrarian Scientific Center, in the structural division of SKNIIMESKh, Zernograd. The task is to conduct a comparative analysis of operation of the new working body with serial ones in preparing the soil for sowing. AIM: Determination of the parameters of a deep tiller for anti-erosion tillage. METHODS: The deep tiller, developed in the department of mechanization of crop production of the Donskoy Agrarian Scientific Center, carries out soil tillage with undercutting of the furrow along the width of the machine, performing non-continuous tilling by working bodies, with appropriate arrangement in the transverse direction. Morphological and functional analysis methods, as well as statistical extrapolation methods implemented in the Microsoft Excel environment were used for data processing. RESULTS: The optimal operating parameters of the proposed new working body for basic tillage have been determined, and a diagram of the force interaction of the working body of the deep tiller with the soil is given. CONCLUSION: As a result of the research, the reasonable parameters of the working body of the deep tiller for antierosion tillage were found, the chisel length, the soil crumbling angle (installation to the bottom of the furrow), the distance between the working bodies in the longitudinal and transverse directions when placed with a ledge at an angle of 30 degrees to the motion direction were determined.
