摘　　要：为了研究马铃薯挖掘机工作阻力大小的影响因素,以挖掘铲为研究对象,分别进行了挖掘铲的受力分析、土壤的受力分析,以及相关辅助参数的求解。同时,构建了挖掘铲工作过程的力学模型,推导出了工作阻力的数学表达式,归纳总结了影响工作阻力大小的相关参数,为后续运用计算机软件进一步对挖掘铲进行力学分析提供了基础依据。In order to study the impact factors of the working resistance, the article analyzed the force conditions of the digger shovel and soil respectively, and solved some related auxiliary parameters, using the digger shovel of potato exca-vator as the research object. Built a mechanical model of the digger shove during the work process ; derived a mathemati-cal expression of the working resistance and summarized the impact parameters. The research work provides the basis for the further mechanical model analysis with the help of computer software.
