Ripping paw tools for preparing the soil for planting

Abstract

The paper discusses parameters of the loosening paw tool to prepare the soil the strip sowing of melons. Scheme of mutual arrangement of the paired housing and the ripper is given. Formulas were obtained for determining the depth of tillage, the width of the ripper and the degree of loosening of the soil, as well as the longitudinal distance between the body and the ripper. The experiments were carried out using the methods of strain measurement and multifactorial experiment. Experiments have established that with an increase in the width of the ripper, the degree of soil crumbling first increases and then decreases according to the law of the convex parabola, and the traction resistance decreases according to the law of the concave parabola. It was determined that to prepare the soil for strip sowing with a minimum traction resistance, the width of the ripper should be in the range of 18.70-20.37 cm, and the longitudinal distance from the ripper to the leaf housing is 42.87-43.57 cm.
