摘要
大方捆打捆机工作过程相对复杂,压缩机构性能是影响草捆压缩成型的关键,直接影响打捆机的草捆成捆密度及作业效率.根据方捆打捆机压缩机构工作原理,采用Creo Parametric软件建立压缩机构三维模型,结合多体动力学仿真软件ADAMS对构建的模型进行运动仿真分析,得到的压缩机构的行程为 740 mm,与计算结果一致.经整机田间试验表明:设计的六道捆绳的压缩机构成型草捆密度在 160 kg/m3 以上,优于评价指标,满足六道捆绳打捆机作业需求.该研究可为六道捆绳打捆机压缩机构的结构设计提供参考.
Abstract
The working process of large square bale baler is relatively complex,and the performance of the compression mechanism is the key to affect the compression moulding of straw bales,which directly affects the bale density and operational efficiency of the baler.According to the working principle of the compression mechanism of the big square bale baler,Creo Parametric software was used to establish a three-dimensional model of the compression mechanism,and ADAMS,a multi-body dynamics simulation software,was used to carry out a motion simulation analysis of the constructed model,the stroke of the compression mechanism was obtained to be 740 mm,which was in agreement with the calculated results.The field test of the whole machine shows that:the designed compression mechanism of six-channel bale rope,the density of moulded hay bales was above 160 kg/m3,which was better than the evaluation index,and meets the operational requirements of six-channel bale rope baler.This study can provide a reference for the structural design of the compression mechanism of the six-channel bale rope baler.
