Improvement of the rotor working parts of the ripping-separating tillage machine providing minimum energy consumption for its work

Abstract

The form of the knife of the rotor of a tillage machine providing the minimum expenditure of energy for its work is substantiated. The work of the rotor working parts of the ripper-separating tillage machine in three positions relative to the soil and separating grid is considered. Three phases of work have been determined: from the moment the knife enters the soil to the separating grid, the moment the knife moves above the separation grid, from the moment the knife moves over the separating grate and to the exit from the soil. The rotor torque is determined by the distance from the surface of the soil of the elementary site, the radius of the rotor, the angle between the direction of action of the normal force and the perpendicular to the radius of rotation of the force, the friction force of the elementary area, the radius of rotation of the elementary area.
