Description
Summary:The existing plows of smooth, furless plowing do not ensure efficient use of the power of energy-rich arable tractors, high-quality soil preparation for sowing and an increase in the productivity of the unit. The aim of the study is to substantiate the parameters of the active working body of the combined frontal plow, which ensures the efficient use of the power of energy-saturated arable tractors, high-quality soil preparation for sowing and an increase in the productivity of the unit. A constructive scheme of a combined frontal plow with active working bodies has been developed. Analytical dependencies are obtained that describe the process of interaction of an active working body with the soil and, on their basis, rational parameters of an active working body are determined. In the research, the laws and rules of theoretical mechanics, mathematical statistics, mathematical planning of experiments and methods of strain gauge were applied. It was found that when the active working body of the combined plow is in the form of an active cutter, its diameter is 572 mm, the number of knives is 5 pieces, the length of the knives is 16 cm and the sharpening angle is 20°, the required quality of plowing is ensured with the least energy consumption. In this case, the longitudinal distance from the nose of the body share to the shaft of the active working body of the combined frontal plow should be 3 cm, the indicator of the kinematic operating mode of the active working body - 2.19 the transverse distance between adjacent working bodies along the shaft of the active working body -26 cm.
