Вплив конструктивних і технологічних параметрів розроблених варіантів борони з гвинтовими робочими органами на ефективність заробляння рослинних решток

Abstract

The purpose of the study is to establish the influence of design and technological parameters of the developed variants of the harrow with screw working bodies on the efficiency of earning plant residues. The object of research is the technological process of tillage with a harrow with screw working bodies. The subject of the study is the patterns of the process of earning crop residues depending on the change in the angle of attack of the working body, the step size of the screw working body and the depth of tillage On the basis of the complex of experimental researches the regression dependences for definition of percent of the area of a surface of a field with full earning of the vegetative rests by a harrow with screw working bodies are deduced. The response surfaces of the percentage of the surface area of the field with the full earning of crop residues ξ during tillage with a harrow with screw working bodies are constructed. It is established that the dominant influence on the percentage of the field surface area with full earnings of crop residues ξ has the depth of tillage h, then the angle of attack β of the battery of screw working bodies and the least affected step size of the screw working body T.
