Abstract
AbstractThe relative motion of a particle along the inner surface of a horizontal concave coulter along a vertical blade installed in the radial direction is considered in the article. The disk rotates around a vertical axis with a given angular velocity. A system of differential equations of particle motion, which is solved by numerical methods, is complicated. Kinematic characteristics were found, the regularities of the relative motion of a particle on the spherical surface were determined. The spherical working surface of the disk allows increasing the dispersion zone of technological material. Analytical description of the particle motion makes it possible to investigate the acceleration during the motion on the disk along with the blades, as well as to find the relative and absolute velocities at the moment of the ascent particles from the disk. The obtained analytical dependencies allow determining the influence of structural and technological parameters on the particle acceleration process.KeywordsWorking surfaceSpherical diskFertilizer particleCoordinate systemDifferential equationsAbsolute velocity
