园艺景观型香蕉树立式切片机设计与试验

Design and Experiment of Vertical Slicer for Horticultural Landscape Banana Tree

提出一种香蕉树干回收利用预处理模式,并以此模式研发了一种香蕉树机械化切片、切散的预处理装置,该装置切片方案是由多把圆盘锯齿刀背刀交错布置于2条动力轴上,2条动力轴放置同一水平面且成一定夹角、相向转动,以此带动切片刀具相向转动切割。先利用CAD软件建立虚拟样机、仿真出几种典型的切片组合方案,再搭建切片物理样机,最后选取动力轴夹角、传送喂料速度、香蕉树干直径和切片刀具动力轴转速为试验因素,探究样机切片功率与各试验因素之间的影响规律。样机切片试验结果表明,该切片机构方案设计可行,影响因素试验结果可用,可为进一步香蕉树回收再利用的机具研发提供参考依据。

According to pretreatment mode of banana tree recycling,a kind of banana tree mechanized slicing device was developed.The slicing device was composed of several disc knife backs arranged alternately on two power shafts,which were placed on the same horizontal plane at a certain angle and rotated in the opposite direction,so as to drive slicing cutter to rotate and cut.Firstly,the prototype was established by using CAD software,several typical chip combination schemes were simulated,and then physical prototype of slicing was built.Finally,the angle of power shaft,feeding speed,banana tree diameter and rotation speed of power shaft were selected as test factors to explore influence law between slice power and various test factors.Results of slicing test showed that scheme design of slicing mechanism was feasible,and the test results of influencing factors were available,which could provide reference for further research and development of banana tree recycling machinery.
