联合机伐木机构的结构设计
摘 要
联合伐木机又名采伐联合机,是一种多功能、 高自动化、高效率的林木采伐机械,在山地采伐作业,联合伐木机显示出无法比拟的先进性。由此,开发多功能的,通过性和适用性好,工作效率显著的联合伐木机 必是今后国内林业机械行业重点研究与开发的方向,同时有着巨大的应用市场。针对目前我国人工林区的发展现状和前景,加快研制适合我国国情、林情的多功能自 动化伐木机械,特别是联合伐木机有着无可厚非的必要性。工作装置是整个联合伐木机的技术核心,其设计合理与否,直接影响到整机性能和作业效率。
本次我所设计的联合机伐木机构为液压剪式伐木机构。本次的设计针对双剪刃伐木机构进行设计。每个结构采用液压驱动。设计完成的联合机伐木机包括夹紧树干的抓瓜、剪刃部分、机架部分、部分。本文对联合机伐木机构及其夹紧树干的抓瓜，剪刃，机架，导轮，对各部分的驱动和电机的选择进行了设计计算，并对齿轮进行校核计算。

Unite the structure of machine lumbering mrvhsnidm design
Abstract
Uniting lumbering machine again to fell to unite machine is a kind of multi-function, the higher - automation, high-efficiency wood fell a machinery, fell an operation in the mountainous country and unite lumbering machine to display the forerunner that can not compare.Developing the multi-function, approval and compatibility is from here good, working efficiency's showing the coalition lumbering of Zhao machine is necessarily the direction of local forestry machinery craft point search and tapping from now on, has an enormous application market at the same time.Aim at currently our country manual Lin Qu's development present condition and foreground, quickly develop suitable our country state of the nation, Lin Qing of multi-function from move to turn a lumbering machinery, especially unite lumbering machine to have a no serious mistakes committed necessity.The operate device is the technique nucleus of the whole coalition lumbering machine, whether its design is reasonable or not and directly effect the whole machine performance and the operation efficiency.
The I design of unite machine lumbering's mrvhsnidm to shear type lumbering mrvhsnidm for hydraulic pressure.This of the design carry on a design to the double shear blade lumbering mrvhsnidm.Each structure adoption hydraulic pressure drives.Design finished coalition machine lumbering machine including to clip grasping of tight tree trunk melon, shear a body deci, bay fraction and fraction.This text scrolls match grasping of the machine lumbering mrvhsnidm and its clip tight tree trunk melon, the shear blade, bay, gride wheel, carried on a design computing to the select of driving of each fraction and the dynamo, and vs the gear carry on schools to calculate calculate.
Keywords：Unite machine lumbering mrvhsnidm；The hydraulic pressure shear type lumbering machine；The hydraulic pressure drives；Shear blade
