Working Body of the Machine for Sowing Cereals on Slopes

Abstract

The study aims to justify the parameters of the ripper tine of the machine for tillage and sowing of grain seeds on sloping fields. The scheme and parameters of the loosening foot of the machine are given. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. The ripper foot consists of a stand, a bit, and a ripper blade. Analytical dependencies for determining the parameters of the bit and ripper blade and the traction resistance of the ripper blade are obtained. It has been established that to ensure high-quality chopping of soil with low energy consumption, the angle of penetration of the plasticizer blade into the soil is within 26-28°, width and length of the working surface of at least 46 and 105 mm respectively, the height of the blade installation relative to the blade In the range 130-150 mm, the installation angle in the range 30-32° relative to the direction of the softening movement of the blade, the width of the cover must be 10 cm. Plasticizer tensile strength depends on its parameters, processing depth, machine speed, and physical and mechanical properties of the soil and ranges from 1.24 to 1.22 kN in the speed range of 1.67-2.22 m/s.
