Design and experimental investigation of a bionic subsoiler with a multiplex-modality shank
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.
