Development of a machine for preparing the soil for sowing melons under the film

Abstract

The purpose of the study is to substantiate the design scheme and substantiate the parameters of the working bodies of the machine for preparing the soil for sowing melons and gourds under a tunnel-type film. The authors proposed a new technology of soil preparation for sowing melons under a tunnel-type film and a combined machine for its implementation. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. It has been established that the most optimal design of the proposed combined machine is considered to be a scheme with a sequential installation of screw bodies with backplows equipped with counter shares, a roller, spherical discs and a furrow cutter with a leveler. According to the results of the research, it was found that with a width of capture of the bodies and a transverse distance between their field edges of 45 cm, a combined machine for preparing the soil for sowing melons under a film using a new technology, a width of capture of counter shares 35 cm, a height of a body share relative to its blade 10 cm, installation angles to the horizon and direction of movement, respectively 34° and 40°, provides an increase in the quality of work and productivity, and with a roller width of 1.35 m, a diameter of 340 mm, an angle of inclination of the slats of the extreme and middle sections of 32°, a height of 4 cm, the number 8 strips of extreme sections and 11 middle sections, longitudinal distance from the nose of the body share to the roller axis 1.4 m, the transverse distance from the nose of the body share to the center of the support wheel 75 cm, the longitudinal distance between the roller and the furrow cutter 35 cm, the height of the furrow cutter 45 cm, length 70 cm, wing opening angle within 30°, leveler height 10 cm, setting angle to the direction of travel 30° is achieved to form the required irrigation furrow with minimal energy consumption.
