Design parameters of circular multidirectional spherical knife tools

Abstract

The aim of the research is to justify the design and geometric parameters of spherical blade working tools for preparing the soil for sowing gourds. The scheme of spherical knife working body is given. The basis of the working body is the thickness of the flange, the crevice of the spherical knife, the depth of treatment, the height of the knife element. Analytical dependences for determining the basic parameters of spherical knife working bodies are obtained. Theoretical researches show that for quality ripping of soil with minimal traction resistance the diameter of spherical blade working elements must be 400 mm, thickness of blade 15 mm, number of knives in blade must be 12 units. The length of the spherical blades is 110 mm.
