Traction resistances of the cotton seeder moulder
Abstract
The purpose of the study is to determine and analyze the traction resistance of the cotton seeder moulder. The moulder of the cotton seeder consists of a visor, two side dumps and a straight part. The forces acting on the elements of the comb shaper are considered. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. Analytical dependences for determining the traction resistance of the moulder depending on their design parameters are obtained. It is established that the traction resistance of the moulder movement depends on the physical and mechanical properties of the soil, the depth of its penetration into the soil, the length of the skids, the width of the input edge of the skids and the angles of installation of the side dumps of the moulder. With the optimal parameters of the moulder, the traction resistance of the sowing unit will increase by 0.6-0.8 kN, which practically does not affect the operation of the sowing unit.
