Investigation results of kinematic and dynamic indicators of tiller with vertical rotation axis in orchards soil cultivation

摘要

The results of experimental-theoretical investigations on the tillers with vertical rotation axis in soil cultivation and weed eradication in orchards are introduced in the article. Upon the developed theory of rotary tiller kinematics and dynamics calculation the following points have been set up: ? In kinematics – functional dependence of the tiller work of technological and regime parameters enabling a high technological quality of soil weed mass cultivation; ? In dynamics – mathematical model of energy evaluation function of soil-weed mass cultivation technological process depending on constructive-regime parameters of the tiller with vertical rotation axis, providing the minimum amount of torque against the resistance towards soil cutting. The reliability of the developed calculation theory has been verified through the results of conducted experiments, the difference hasn't exceeded 5%, which is explained by the inhomogeneity of the treated medium and changeability of the straightness of the garden rows.
