精密播种制钵机的机构设计及计算机辅助分析

目前,我国农业育苗播种中,所采用的播种制钵机还属于机械化范畴,不具有自动化水平,不能有效实现精密播种需求。为此,分析精密播种制钵机优化设计的需求,并结合Pro/Engineer软件辅助分析,优化了设计参数。结果表明:设计出的精密播种制钵机的机械结构简单、性价比高,降低了使用中钵体的破损率(降低12.0%),提升制钵机工作可靠性(提升2 0.0%),具有较大的经济效益。基于计算机辅助分析方法 ,优化设计精密播种制钵机的机构,可提升精密播种制钵机应用性能。

Computer Aided Optimization Design of the Mechanical Structure of Precision Seeding Machine

The purpose of this paper is to study the mechanism design and application of the computer aided analysis of precision seeding machine .For in our country when the agricultural seeding , the seeding machine for making pots also belong to the category of mechanization , automation level , can not effectively achieve precision seeding demands , this a-nalysis precision seeding bowl making machine optimization design demand , combined with computer software Pro /Engi-neer , and assistant analysis and optimization of design parameters .Results confirmed , not only design the precision see-ding of bowl making machine mechanical structure is simple , and the price is high , reduce use of the bowl body breakage rate, reduce 12.0%, to improve the reliability of the work bowl making machine , enhance the 20.0%, play a positive effect in application .The conclusion shows that , based on the computer aided analysis method , the optimization design of the mechanism of the precision seeding machine , exert positive influence and improve the application performance of pre-cision seeding machine .
