The soil preparation machine for seeding potatoes on comb

The aim of the research is to substantiate the main parameters of the machine working elements for preparing the soil for sowing on the ridges and their mutual location. The authors have developed a machine that performs all technological operations to prepare the soil for sowing potatoes on the ridges in one pass in the field. The machine performs surface loosening of the soil, strip deep loosening of the soil, formation of ridges, loosening of the surface layer of the ridge top, compaction, and giving them a trapezoidal shape in one pass. The design of the developed machine for the realization of technology of preparing the soil for potatoes sowing is resulted. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. Theoretical studies established the following parameters of the working bodies of the machine: the working width of the bodies 200 mm, length of the blade wing 515-545 mm, angle of slope of the ploughshare left to its base 60, length and height of the guide knife respectively 150 mm and 80 mm, the longitudinal distance between the bodies within 350-400 mm, width and length of the drill bit 80 mm and 115 mm respectively, the working width of the lancet leg 150 mm.
