Design and Experimental Investigation of a Bionic Subsoiler with a Multiplex-Modality Shank

Abstract:

Based on study of animal-claw morphology, a multiplex-modality subsoiler is designed with an intention to decrease its operating resistance. Design concepts and structure scheme of the subsoiler are presented. To analyze the performance of multiplex-modality subsoiler, a multiplex modality sub-soiling shovel and a national standard regulated arc-shape subsoiler (JB/T 9788-1999) are tested in soil bin. Effect of tillage depth and operating speed on the operating resistance of sub-soiling shovels is examined. Type of subsoilers, tillage depth and forward speed, with 2, 3 and 3 levels taken respectively, are considered in experiment. Experiment results show that the multiplex-modality subsoiler, compared with the standard arc-shape subsoiler, sees much lower operating resistance and power requirement against soil. Resistance-decreased index of the multiplex modality subsoiler are 45.3%, 34.4% and 34.2% at 300, 350 and 400mm cutting depth, respectively.
