Experiment on working performance of bionic blade for soil-rototilling and stubble-breaking

In order to examine the power consumption and working quality, the bionic blades for soil-rototilling and stubble-breaking (bionic blade for short), national standard rototilling blades and common stubble-breaking blades were mounted respectively on rototilling-stubble-breaking machine to perform soil-rototilling and stubble-breaking tests. The power consumption of the three kinds of blades were tested by electric measurement method respectively, and the working qualities were tested in accordance with national standards. Because of the difference of blades' soil-cutting range, the power consumption of unit area of soil-cutting was taken as test index. The results showed that the power consumption of unit area of soil-cutting of bionic blade was less than that of national standard rototilling blade, and the working quality of bionic blade was better than that of the national standard rototilling blade. The power consumption of unit area of soil-cutting of biomimetic blade were less than that of common stubble-breaking blade, and the working quality of stubble-breaking of biomimetic blade was little worse than that of the common stubble-breaking blade, but it met the requirement of national standard of China. The research provided a reference to achieve soil-rototilling and stubble-breaking by using one kind of blade.
