Description
Summary:Currently, in order to increase the productivity of a unit, high-speed tillage working bodies are widely used. The purpose of the work: to determine the operating modes of a high-speed working body that performs the technological process of tillage efficiently with the lowest energy costs. It was found that at a low speed (6-8 km/h), the productivity of a unit decreases, and at a high speed (over 12-15 km/h) – an increased degree of soil crumbling leads to soil dispersion and erosion. We obtained the expression for determining the characteristic size of a clod (up to 50 mm and up to 25 mm for deep and shallow tillage, respectively) as a qualitative parameter of the technological process, depending on physical and mechanical properties of a treated medium and the mode of operation of a working body (speed). The function that reveals the relationship of a working body parameter (the crumbling angle of 20-25o and 10-15o under deep and shallow tillage, respectively) with the operating mode of a unit (speed of 10-12 km/h and up to 14 km/h under deep and shallow tillage, respectively), taking into account changes in the angles of external and internal friction at different soil hardness and humidity was obtained. The expression that reveals the relationship of the parameter of a working body (the angle of crumbling) with the qualitative parameters of the technological process (characteristic size of a clod) and energy (traction resistance 4.8-7.9 kN and 2.1-3.7 kN under deep and shallow tillage, respectively), taking into account the physical and mechanical properties of the treated medium, was obtained as well.
