Theoretical substantiation of the parameters of the active working element of the combined frontal plow

Theoretical substantiation of parameters of active working element of combined frontal plow is considered in order to effectively use power of energy-saturated arable tractors to improve quality of soil preparation for sowing and productivity of the unit. The study applied the methods of classical mechanics. It was established that when the active working element of the combined plough is made in the form of an active milling cutter (with a diameter of 540... 560 mm, with 5 knives having a length of 16 cm, an angle beyond the point of 20° and an angle of 30° of installation relative to the shaft), the required quality of plowing is ensured with the lowest energy costs. The study found that the required quality of soil treatment with minimal energy consumption is ensured at a longitudinal distance from the toe of the ploughshare to the shaft of the active working element of the plow within 16... 34 mm, kinematic mode of operation 2.5, transverse distance between neighboring working elements 235.3 mm.
