In order to improve the working performance of cassava harvester, structural bionic design for its digging shovel was conducted. Taking the oriental mole cricket's paws as bionic prototype, a new structural bionic design method for digging shovel was established, which considers the morphology-configuration-function coupling bionic. A comprehensive performance comparison method was proposed, which is used to select the bionic design schemes. The proposed bionic design method was used to improve digging shovel structure of a digging-pulling style cassava harvester, and nine bionic-type digging shovels were obtained with considering the impact of soil mechanics. After conducting mechanical properties comparative analysis for bionic-type digging shovels, the bionic design rules were summed up, and the optimal design scheme of digging shovel was obtained through combining the proposed comprehensive performance comparison method with Analytic Hierarchy Process (AHP). Studies have shown that bionic design method not only can improve the overall mechanical properties of digging shovel, but also can help to improve the harvesting effect of cassava harvester, which provides a new idea for crops harvesting machinery's structural optimization design.

考虑土壤力学的木薯收割机挖土机结构仿生设计

为了提高木薯收割机的工作性能,对其挖土铲进行了仿生结构设计。以东方mole的爪子为仿生原型,建立了一种新型的仿生挖土铲结构仿生设计方法,该方法考虑了形态—构型—功能耦合仿生。提出了一种综合性能比较方法,用于选择仿生设计方案。提出的仿生设计方法被用来改善木薯收获机的挖土铲结构,在考虑土壤力学影响的情况下,获得了九把仿生挖土机。在对仿生挖土机进行力学性能比较分析后,总结出仿生设计规则,通过将综合性能比较方法与层次分析法相结合,得出了挖土铲的最佳设计方案。研究表明,仿生设计方法不仅可以提高挖土机的整体力学性能,而且可以帮助提高木薯收割机的收割效果,为农作物收割机械的结构优化设计提供了新思路。
