THE RESULTS OF EXPERIMENTAL AND THEORETICAL STUDIES OF A MODEL OF A SOWING COMPLEX WITH DIFFERENT VALUES OF ROW SPACING AND VIBRATING DISC COULTERS

The article is devoted to the interaction of the disk vibration working bodies of the sowing unit with the soil. To reduce the forces of traction resistance and energy intensity of tillage, increase the speed and productivity of sowing units, patterns characterizing the effect of vibrations on the soil have been identified and a mechanical and mathematical model of cutting soil with a vibrating disc working body of a sowing unit has been developed, mathematical dependencies have been obtained to determine the parameters of vibro-impact interaction of the cutting edge of a disc working body with the soil and conditions for the effectiveness of the vibration cutting process have been established from the point of view of reducing the traction resistance and energy intensity of the process. A method for selecting rational parameters of soil vibration cutting in the design and operation of a disk working body of sowing equipment has been developed. The results of experimental studies of a prototype of vibrating working equipment are presented, confirming the theoretical results obtained and proving the effectiveness and expediency of vibrating cutting of soil with a disk working body to reduce traction resistance and energy costs.
