The dependence of the quality of soil treatment on the parameters and operating modes of the working bodies of the cutter

Abstract

Abstract The purpose of the field research was to verify the theoretical assumptions, calculations and comparative tests in the economic conditions of the mill. The object of research was a milling cutter with a horizontal axis of rotation of working bodies. The dependence of the quality of soil treatment on the parameters of the cutter: the speed of the unit, the circumferential speed of the knife, the depth of soil treatment is determined. Regression analysis methods are used to search for a regression equation that adequately describes the quality of soil cultivation from the studied parameters. It was found that the values of the homogeneity of the fractional composition of the soil during processing by the working bodies of the cutter meet the agrotechnical requirements at the values of the kinematic parameter λ=4 and the processing depth a=0.14 m. The best indicators of the fractional composition of the soil were obtained when the drum diameter D=0.4 m and the number of cutter knives in one plane Z=3-4 PCs. The purity of tubers in the combine hopper ranges from 10 to 30%, which is 1.5 times lower compared to the control area.
