Analytical research results of the combined root digger

Abstract

This paper researches the operation principle structure of a combined root digger that consists of two spherical disks and, above them, a horizontal shaft with cleaning blades. Mechanical and technological justification of structural and kinematic parameters and operating modes of combined digger was carried out based on the analysis of technological process of roots excavation. The dependence of digger operation on the condition of providing complete digging of the root crops is obtained. Deterministic mathematical models of the interaction between the cleaning blade and the root head provided no not dumping and non-damaging of root, were developed.
