The quality of loosening the soil with subsoilers of the combined machine //IOP Conference Series: Materials Science and Engineering. – IOP Publishing, 2021. – Т. 1030. – №. 1. – С. 012171.doi:10.1088/1757-899X/1030/1/012171https://dspace.kstu.uz/xmlui/handle/123456789/1164The aim of the study is to study the influence of the parameters of subs oilers on the quality of loosening of the soil when preparing the soil for sowing melons and gourds under a film with a combined machine. The authors have developed a combined machine for preparing the soil for sowing melons and gourds under a film. The structural diagram of the developed machine is presented. Theoretically, the completeness of loosening of the soil by subs oilers of the machine is determined from their parameters and relative position. Theoretical and experimental studies have established that the scheme of pair wise arrangement of subs oilers inclined to the right and left of the combined machine with working surfaces facing each other, as well as shifted relative to each other in the longitudinal plane, provides the required quality of work, while the longitudinal distance between the subs oilers should be 75 cm, and the transverse distance is 60 cm.enArticle
