【摘要】 基于保护环境的原则,针对传统植树挖坑机的缺点,研发了一种挖坑质量高、速度快、安全可靠、劳动强度低、挖坑成本低以及能适应不同坑深要求、地形变化和土壤硬度等条件的新型植树挖坑机。分析了植树挖坑机的工作原理,对刀盘进行了受力分析,采用APDL参数化设计语言建立了挖坑机各零件的有限元模型。有限元分析的结果表明:新型行走式植树挖坑机能够满足工作要求,并且挖坑机的各零件能够满足刚度和强度要求。更多还原

【Abstract】 Based on the principle of protect environment and the shortcomings of the traditional digging machine,this paper designs a kind of new diging machine which is high quality,fast,safe,reliable,low labor intensity low cost and can adapt to different requirements of pit depth,topography and soil conditions.This paper analys the new type digging machine’s working principle,force analysis of cutter disc.The main parts of the diging machineon are established by APDL parameter design language.The results show that the main transmission chain of way can meet the job requirements of loader and the main parts can satisfy the intensity and rigidity requirements.更多还原
