Design and experiment of strip collection machine for seed melon based on ADAMS
Aiming at problems of high leakage rate and low vine separation rate in process of seed melon strip collection,a profiling seed melon strip collection machine was designed.Using a parallel four-bar linkage combined with springs to achieve ground profiling,main factors affecting stability of profiling mechanism's ballast pressure were determined through theoretical analysis.By using ADAMS software,spring stiffness,load and operation speed were taken as test factors,and fluctuation of pressure of set roll was taken as evalu-ation index,simulation tests were carried out.Data processing and analysis of simulation test results were carried out,and response sur-face method was adopted to optimize optimal parameter combination.When local wheel spring stiffness was 5.2 N/mm,machine load was 1 435.78 N,and operating speed was 1.02 m/s,stability of pressure suppression roller was optimal,with a pressure fluctuation rate of 9.87%.Based on optimized parameter combination,field validation experiments were conducted using leakage rate and melon vine separation rate as experimental indicators.Average leakage rate was 0.62%,which was relatively low,while average melon vine separ-ation rate was 90.05%,which was relatively high.
