Dotsenko M. Improvement of technological sowing process with forming a wavy furrow.

Object of research – disk opener of a grain seeder. The purpose of research - increase of efficiency of crop at the expense of formation of a twisting groove. Methods of research both instrumentation - theoretical and experimental methods. Theoretical results: investigated rational parameters opener for formation of a twisting groove. Practical outcomes - develop opener provides erosion-protection crop at the expense of formation of a twisting groove and improves uniform of accommodation of seeds on width of a groove. Novelty - with the help of of developed mathematical model the parameters opener for formation of a twisting groove are certain. A degree of introduction - outcome of activity are adopted for use by Kirovograd opened joint-stock company " a Red star " at desining of opener of a seeder. The seeder is arranged experimental openers was tested in facilities of Kharkov area. Thus the increase of productivity on 6-8% is marked. Orb of use - firm on manufacturing of seeders and facilities.
