Raking plates of the combination machine's subsoiler

The purpose of the research is to justify the type of subsoiling plates of the machine for preparing the soil for sowing melon crops. The machine designed by the authors for the preparation of the soil for sowing melon crops under the tunnel film is equipped with deep loosening subsoilers of “paraplough” type with loosening plates. The scheme of subsoiler arrangement on the frame of the machine is shown. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. The scheme of subsoiler arrangement on the frame depending on their parameters has been theoretically justified. Experimental studies have established that using a subsoiler in the form of a rod and plate with a length of 12 cm and a height of 20 cm provides the required crumbling of the soil at minimum energy consumption.
