SUBSTANTIATION OF THE SIZE OF A COMBINED DEVICE FOR TILLAGE AND SOWING

abstract 1592005008 issue 159 pp. 122 – 132 29.05.2020 ru 157
The article presents a methodological approach to the rational selection of the optimal working width by the example of a combined tillage unit using original software. To select the optimal working width of a combined soil cultivating unit, the initial data are: make (type) of the tractor (power tool), unit cost of the machine and tractor unit in comparable prices, production time of the machine and tractor unit to perform the technological operation at a given operating speed with a clear compliance with agrotechnical requirements, both to the technological operation itself, and, directly, to the agricultural machine. As an example, we consider a combined semi-mounted modular tillage and sowing unit for grain crops and the MTZ-82.1 tractor. In this unit, the main working bodies are S-shaped spring teeth and rollers. Based on the performed analytical studies of the pre-sowing (surface) tillage process and the application of theoretical modeling methods, mathematical dependencies have been developed to determine and further analyze the energy-technological parameters of combined tillage units with dynamic working bodies. The performed calculations according to the developed method allow us to choose the optimal working width of the combined soil cultivating unit
