Substantiation of the parameters of the rotary ripper of the machine for pre-seeding treatment of ridges

Abstract

Taking into account the fact that the ridge technology of cultivating crops is becoming widespread in the country, and there are no special technical means for pre-sowing treatment, a machine has been developed for processing ridges along their entire profile in one pass, consisting of a frame and support wheels mounted on it, lancet paws, rotary rippers and slatted rollers. The article presents the results of theoretical and experimental studies to substantiate the parameters of the rotary cultivator of the developed machine. According to the results of the research, it was found that for the qualitative implementation of the technological process of processing the slopes of the ridges and ensuring the required quality of soil crumbling on them, the length of the bar of the rotary cultivator must be at least 320 mm, the small and large diameters of its conical rollers, respectively, within 200-250 mm and 400- 450 mm, the number of its slats is 12-14 pieces, the width of the slats is 30-32 mm, as well as the vertical load on it in the range of 0.50-0.60 kN, the longitudinal distance between the lancet share and the rotary ripper is 60 cm .
