Design and Experiments of a Bionic Hook-shape Subsoiler
Based on the study of morphology of animal claws, a bionic hook-shape subsoiler was designed to decrease its operating resistance and to improve the terrain surface morphology. Design concepts and the structure scheme of the subsoiler were presented. The influences of tillage depth and operating speed on the operating resistance of the bionic hook-shape subsoiler were examined in soil bin tests by comparing with a standard arc-shape subsoiler regulated by national standard (JB/T 9788-1999). It was proved by the results that the bionic hook-shape subsoiler, compared with the standard arc-shape subsoiler, showed much lower operating resistance and power requirement against soil. The resistancedecrease index of the bionic hook-shape subsoiler was 24.1％, 24.4％ and 26.5％ at 300, 350 and 400mm cutting depth, respectively.
