林木采伐头的发展历程及现状研究

摘要

M ulti‐function harvester is the best harvesting machinery ,as the key component of the harvester ,the design of harvester head directly determines the performance of harvesting machinery .This article reviews the development course and current situation of harvester head at home and abroad ,introduces the development technology and characteristics of harvester head in different periods ;finds out the gap in harvester head technique between our country and developed country ;and points out the development trend of harvester head .%多功能联合采伐机是当前性能最好的采伐机械，而作为采伐机的关键部件，采伐头的设计直接决定了采伐机械的性能。综述了国内外采伐头的发展历程与现状，介绍了不同时期的采伐头发展技术、特点及其优缺点；通过国内外发展对比看出我国采伐头技术与国际先进技术之间的差距所在；并指出采伐头的发展趋势。
