Simulation Analysis of Arc-jaw Type Potato Precision Seed Discharger
摘要
Abstract
Aiming at the unstable problem of single seeding during the sowing process of potato,the basic physical properties of the potato seed were determined with the Enshi selenium-enriched potato seed as the research object.The triaxial dimensions,volume and density of potato seed were measured,and the dimensional structure of the seed displacer was modeled in three dimensions according to the parameters of the seed.The seeding process of the arc-jaw potato seeder was simulated using Recurdyn-EDEM coupled simulation,and the parameters were optimized by response surface test.Taking the effective seed picking length(X1)and seed scoop width(X2)as the test factors,and the single-grain rate,multiple-grain rate and empty-grain rate as the test indexes,the quadratic generalized rotary combinatorial design test was conducted with the coupled simulation.The results showed that X22 and X22 had significant effects on single grain rate,multi-grain rate and empty grain rate,and X1 and X1X2 had significant effects on multi-grain rate and empty grain rate,while the rest factors had non-significant effects on the index.Using the optimization module to optimize the data of parameters,and the best parameter combination of effective seed length and seed spoon width was determined as 99.74 and 60.02 mm.Under the optimized parameter,the error value between the simulation test and the target value was less than 2%and the single grain rate was greater than 80%,which proved the accuracy of the optimized experimental parameters,and the feasibility of the precision seeding rate.关键词
