Virtual Design for Self-elevating Seed Collecting Machine Based on UG

Wu Hao,Dong Xibin(College of Engineering and Technology,Northeast Forestry University,Harbin 150040,P.R.China);Li Jinpeng(Chery Automobile Co.,Ltd.);Wang Yaqiong(Sichuan Normal University)  
The characteristics of a new self-elevating seed collecting machine were proposed according to the status of tree seed production and harvesting in China.A three-dimensional virtual model of seed collecting machine was established by Unigraphics(UG),which was used for movement simulation.The moving platform was introduced into agriculture and forestry machinery,and the structure and working principle of the moving platform were studied in order to improve the working ability of seed collecting machine under the conditions of rough ground and steep slope.The hoisting mechanism which could meet requirements of forest operation and picking seeds from topmost branches was designed.A great number of problems on mechanism matching and movement rationality were solved through studying the virtual model of seed collecting machine,and the design scheme was also optimized.
