Traction resistance of the combined machine plough

Abstract

Subsoils are widely used on tillage and combination machines. The tiller of the combined machine for preparing the soil for sowing melons and gourds carries out strip loosening of the subsoil layers. The study aims to theoretically determine the traction resistance of a soil deepener of a combined machine for preparing the soil for sowing melons and gourds. The study uses the basic provisions of mathematics, theoretical mechanics, and agricultural mechanics. In studies, it is assumed that the destruction of the soil under the influence of the drill bit occurs by separation. The total traction resistance of the subsoiler was determined as the sum of the resistance of the rack and the bit. An analytical expression has been obtained to determine the traction resistance of a tilting machine with an inclined stand, depending on its design, technological parameters, and the physical and mechanical properties of the soil. As a result of theoretical studies, it was found that the traction resistance of the soil deepener is mainly influenced by its design parameters, the depth of soil cultivation, the physical and mechanical properties of the soil, and the speed of the machine.
