初稿树木移植车提升及液压系统设计.docVIP

摘要 近年来，国内的城市化进程加快了许多，在城市建设中，随着绿地面积的不断发展扩大以及人们对生态绿化的要求的提高，树木移植变得越来越普遍和重要。不过，国内的树木移植主要靠人力来完成，不仅耗费许多人力物力资源，效率不高，而且成活率也比较低。树木移植车的发明在很大程度上改善这种情况，提高树木移植的效率，减轻工人的劳动量，同时也提高了移植成活率。 本文介绍了有关树木移植机的历史以及在国内外的发展现状，并在此基础上选定树木移植机作为课题进行研究设计。参考了国内外有关资料，并在导师的指导下进行自主设计，以树木移植机的各项数据，如结构参数、作业要求、性能、动力要求等为基础进行研究设计，灵活运用所学知识进行树木移植机的机械结构设计以及液压系统设计。 树木移植机是城市树木移植的最有力的机械工具，树铲是移植机的主要工作部分。本设计的树木移植机用于树木的挖掘和移植，设计有4把铲刀，铲刀角为25°。该移植机在工作时可挖掘的土球直径为680mm，挖掘深度为600mm，提升高度为600mm。 此次设计共有4组液压缸，包括挖掘机构铲刀液压缸、开合机构液压缸、提升机构液压缸和倾斜机构液压缸。 本次设计的树木移植机具有工艺简单，成本低，适用性高等优点。不仅能够用于城市园林绿化，在大面积造林时也能发挥出不错的效果。树木移植机将会改变现有的植树模式。 关键词：树木移植机，铲，提升倾斜，液压 Abstract In?recent?years, the?rapid?of?urbanization’development?is faster in?our?country. In the city’s construction, with the constructions development of the residential areas and the requirement rise ceaselessly to virescence, tree transplanting becomes more and more universal and important. But in out country it still work manual operation with labor intensive, it costs a lot human resources. What’s more, the survival rate and efficiency is not high. The invention of the tree transplanter will change the complexion. It can be use to improve the efficiency, reduce labor intensity, etc. The history of the tree transplant machine and the present development situation at home and abroad were introduced in this paper, and on the basis of chosen trees transplanting machine as a subject to study and design. Refer to the relevant data at home and abroad, and under the guidance of tutor for independent design, using all kinds of data of trees transplanting machine, such as the structure parameters and operation requirements, performance, power requirements, etc. Based on research design, using knowledge flexibly in trees transplant machine mechanical structure design and hydraulic system design. The tree transplanter is the most advantageous mechanical tool for the implementation of transplanting trees, the tree spade is an important part of the tree transplanter. The design of the tree transpl
