THE INFLUENCE OF THE ANGLE OF ENTRY OF THE LOOKING PAW INTO THE SOIL ON ITS DRIVING RESISTANCE

Abstract

In the aisles of seedlings of fruit trees in new orchards, it is possible to receive additional income within 5-8 years by sowing and growing various vegetable and gourd crops, however, most farms do not use this opportunity. The reason for this is that in order to prepare for sowing, the soil plowed in early spring in the passages of gardens should be loosened, clods should be crushed, the surface - leveled and irrigation furrows - cut. When performing these works, at present, each technological process needs a separate passage of the corresponding agricultural unit. However, this leads to an increase in labor, time and energy costs. Considering the foregoing, this article presents findings from a research into the development of a design for a combined unit that performs a range of works, in one go, on preparing the soil for sowing when growing vegetable and gourd crops in the garden passages, as well as determining some parameters of the working bodies of this unit. In particular, a method for determining an optimal angle of entry into the soil of the loosening paw of the developed unit and the traction resistance of this working body is shown. As a result of the research, in view of effective and high-quality operation of the unit, the optimal angle of entry of the loosening paw into the soil was worked out as α_max = 25...35^o, as well as the traction resistance of this working body – as R = 320...400 N, while, the values of the width of the paw and the depth of tillage are taken equal, respectively b = 0.04...0.06 m, h = 0.15 m.
