| 摘 要： | 对影响木薯收获的因素进行分析,借鉴马铃薯收获机挖掘铲的设计思想,在铲面受力分析的基础上,引入了土壤压缩和破坏理论,建立了运动条件下挖掘铲的碎土性能分析模型。应用Matlab软件对该模型进行了数值计算,并对平面挖掘铲进行了碎土性能分析,得到了最佳的平面铲倾角,提高了木薯挖掘铲的碎土性能,为木薯挖掘铲的设计提供了理论参考。

| Abstract: | Through analyze the effect of cassava harvest factors,and borrow design idea from the potato harvester digging shovel,the soil compression and failure theory which is based on the force analysis in shovel face is introduced in the paper.It is also established crashing soil analysis model under movement condition,calculated the model with matlab software,and make the crashing earth analysis to the plane digger digging shovel to get the optimal dip angle.It improved the crashing earth nature of plane digger b... |
