Vliv síly v horním táhle závěsu traktoru na spotřebu a výkonnost souprav na zpracování půdy
Drašar, Jan
The aim of the thesis was to analyze the measured values from measurements. In the research part of the work, an overview of the technologies used for soil processing was processed. Here are the basic tillage systems (conventional tillage, conservation tillage and direct seeding). Soil processing technologies such as ploughing, mulching, strip processing or loosening without turning topsoil are also summarized here. In the final part, the machines used for tillage were described. The methodology described the measuring devices and individual plowing sets that were used to measure the output data of the plowing sets. When evaluating the data, the main parameters were the specific effective fuel consumption, specific effective efficiency, hectare effective efficiency and slippage of the drive wheels depending on the force in the upper link and the pressure in the traction cylinder of the selected tractor sets. The diploma thesis was prepared from 3 field measurements, a total of 71 measurements were made. Individual measurements were analyzed and it was shown that the length of the upper drawbar increases the average specific efficiency by 17%, the hectare effective efficiency by 20%. Furthermore, it has been shown that the average consumption will decrease by 6% and the increase will decrease from 2% to 7.5% on average.
