Justification of the bottom softening parameters of working organ with a sloping column

Abstract

At present, cultivator plows used in horticulture in Uzbekistan have a number of serious shortcomings. Their quality of work does not meet agrotechnical requirements. The purpose of study is to substantiate the parameters of lower ripper the working body with an inclined rack. The authors proposed a working body with an inclined rack, equipped with upper and lower rippers. The lower ripper loosens the lower soil layer. The scheme of a plow-ripper with improved working bodies is given. Theoretical studies were carried out using the laws of theoretical mechanics. In experiments, the height of irregularities at the bottom of arable land and traction resistance were taken as a criterion for evaluating the performance of a plow-ripper. Based on the results of theoretical studies, dependencies were obtained that allow determining the parameters lower ripper. According to the results of this proven research, the coverage width the bottom softener is in the range 9.5-9.9 cm, and its grinding angle is in the range of 16,3-27º, in order to ensure the required level of coulters in the bottom the plow. The angle of installation the blade in relation to the direction of movement should be 30º.
