The machine for the preparation of the soil in sowing of plow crops under film

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.
