称重式水果分选机在水果分级市场应用最为广泛,对其传统的研究方法是以二维平面图来设计其结构,抽象且很难修改.因此利用SolidWorks软件设计了一种新型称重式水果分选机,通过SolidWorks实现了对托盘称重式水果分选机支架、托盘、传动系统和链轮轴的设计,建立了电动机减速器和轴承座的三维模型,最终实现了称重式水果分选机的整体装配,系统的对分选机零件进行三维建模、虚拟装配、干涉分析和初步的有限元分析.结果表明,SolidWorks有助于新型农业机械的设计,缩短了其开发周期,提高其设计的质量.%Fruit sorting machine of weighing type was used most widely in fruit grading market, which study on its structure adopting traditional 2D plan method is too abstract to modify hardly.The re fore a new weighing type of fruit sorting machine was designed using SolidWorks, through which the design for stents,tray institutions ,transmission system and sprocket shaft of the sorting machine was realized,and 3D model for the motor reducer and bearing socket was built so that the overall assembly for the fruit sorting machine was achieved-Afterwards ,3D modeling,virtual assembly as well as compute clash and primary FEM analysis were carried out for parts of machine. The application results show that Solidworks is beneficial to new agricultural machinery design,which shall shorten the development cycle and improve the design quality
