I拖拉机后部挖掘机具摆臂设计【摘要】拖拉机后挖掘机具，是拖拉机功能的工程拓展，在国外，拖拉机后挖掘机具已经发展得非常成熟，机具的安全性和稳定性都比较好，国内与之相比还有一定的差距。拖拉机后挖掘机具的工作性能与挖掘装置的设计有很大的关联，本文通过对拖拉机后挖掘机具的研究，通过严密的计算方法，设计一种有较好的安全性和稳定性的拖拉机后挖掘机具，希望可以在提高挖掘机具反铲挖掘装置性能方面提供一些具有实践性意义的思路。【关键词】拖拉机后挖掘机具，反铲挖掘装置 IIAbstractAfter tractor excavating machine tools, it is the development of tractor function engineering. In foreign countries, the rear tractor excavator has developed very mature, the safety and stability of the machine tools are good, and there is a certain gap compared with it in China. There is a great connection between the working performance of the tractor rear excavator and the design of the excavator. Through the study of the tractor rear excavator, this paper designs a kind of rear tractor excavator with better safety and stability through the rigorous calculation method, and hopes to improve the performance of the excavating device of the backhoe of the excavator. Some practical ideas are provided.Key wordstractor rear excavating machine, backhoe digging deviceIII目 录【摘要】............................................................I【关键词】..........................................................IABSTRACT...........................................................IIKEY WORDS..........................................................II1.绪论..............................................................11.1 拖拉机后挖掘机具概述.........................................11.2 拖拉机后挖掘机具分类.........................................11.3 国外拖拉机后挖掘机具发展概况.................................11.4 国内拖拉机后挖掘机具发展概况.................................21.5 研究意义与主要...
