Substantiation of the arrangement and parameters of the loosening compacting discs of tillage rollers with a bionic approach
The article presents the methods and results of bionic modeling in agricultural mechanics, which made it possible to substantiate the arrangement and parameters of the working bodies of the loosening compacting discs of tillage rollers adapted to the soil environment using the regularities of the arrangement of thorns on wide rings of the tail in the biological prototype of the girdle tail (Cordylidae). Based on the principle of multi-contact action of the teeth and toothed plates of the roller discs on the soil layer, the coefficient of the arrangement of the discs on the roller is equal to 0.22 ... 0.24, as well as the number of toothed plates and teeth on the working surface of the loosening compacting disc of the roller, which is in the range of 6 ... 12, which is consistent with the arrangement of spines along the circumference of the wide rings on the tail of the girdle. The results of experimental studies, confirming the decrease in the traction resistance of the proposed working bodies of the loosening compacting discs of tillage rollers for surface tillage are presented.
