In the world much attention is paid to the development and application of machines that perform all technological processes of soil cultivation and preparation of soil for sowing crops in one pass on the field. The aim of the research is to substantiate the constructive scheme and mutual arrangement of the working elements of the machine for preparing the soil for sowing melon crops under the tunnel-type film. The authors proposed new technology for preparing the soil for sowing melon crops under the film of the tunnel type in one pass of the machine, including the surface loosening of the covered soil, milling-free loosening and formation of irrigation furrow along the axis of symmetry of the sowing zone, preparing the strip of soil for sowing melon crops under the film of the tunnel type. The design of the developed combined machine for the realization of the offered technology is resulted. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. It is established that the most optimal design scheme of the machine is considered to be a scheme with a sequential installation of a lancet leg, pairs of deep loosening machines, furrow cutters, and rotary working elements inclined to each other. It is theoretically proved that qualitative preparation of the field for sowing melons with minimum energy consumption is provided with the longitudinal distance between the deep loosened and the lancet leg of 40 cm, the transverse distance between the deep loosened and the support wheel of 10 cm, the longitudinal distance between the deep loosened and the furrow cutter of 50,6 cm, the longitudinal distance between the furrow cutter and the rotary working device of 123 cm.
The aim of the study is to develop a machine for preparing the soil for sowing melons under a tunnel film. The authors have developed a machine for preparing the soil for sowing melons under a tunnel film, which is equipped with deep-diggers with an inclined stand of the “paraplau” type, a furrow maker and rotary working bodies. A design diagram and a fragment of the machine operation have beak given. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. Tests have established that the developed machine reliably performs the specified technological process and its performance indicators fully meet the requirements. When using the developed machine for preparing the soil for sowing melons under the film, the direct cost of processing one hectare of area is reduced by 33.4%. The study’s goal is to create a machine that prepares soil for seeding melons under a tunnel film. The authors have created a machine that includes deep-diggers with a “paraplau” style inclined platform, a furrow maker, and rotating working bodies for preparing the soil for planting melons beneath a tunnel film. A design schematic as well as a portion of the machine functioning has been provided. In this work, the fundamental concepts and methodologies of classical mechanics, mathematical analysis, and statistics were employed. The created machine reliably executes the required technical procedure, and its performance indicators completely fulfill the criteria, according to tests. The direct cost of processing one hectare of land is lowered by 33.4 percent when utilizing the developed machine to prepare the soil for growing melons beneath the film.
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.
