DERIVATION OF THEORETICAL DEPENDENCIES AND DETERMINATION OF GEOMETRICAL PARAMETERS AND OPERATING MODES OF NEW STRUCTURAL UNITS OF EQUIPMENT INCLUDED IN THE SEEDING COMPLEX

Abstract

The article is devoted to the interaction of the disc working parts of the seeding unit with the soil. The reasons for the increase in traction resistance forces and energy intensity of soil cultivation, the decrease in the stability of the cutting depth with an increase in the operating speeds of sowing units with disk working bodies are outlined. A theoretical model of cutting soil with a disk working body has been developed, a mathematical dependence of the cutting resistance force on the speed of the working body and variable soil properties has been obtained, explaining the facts of increasing energy intensity and reducing the quality of the cutting process. Measures have been proposed to reduce traction resistance forces and energy intensity of soil cultivation, and increase the stability of the cutting depth. The results of experimental studies of the processes of static and vibration cutting with a disk working body are presented, confirming the theoretical results obtained and proving the effectiveness and feasibility of using vibration cutting of soil with a disk working body to reduce traction resistance and energy costs and stabilize the cutting depth in a wide range of operating speeds.
