Parameters optimization and experiment of corn-paper transplanting machine with seedling disk

Abstract: Seedling transplanting technologies can greatly improve crop yield, in order to further improve the seedling planting quality of transplanting machine, the working parameters of disc type planting apparatus of corn transplanter were analyzed, the influence law of working parameters on the plant quality was studied through soil-bin test. The orthogonal rotation combination test was conducted, which took location of furrow opener, the depth into the soil of furrow opener and backfill shovel inclined angle as input variables, and took upright degree and coefficient of variation of row spacing as response. By using Design-expert regression analysis method and response surface method, the effects of three factors on test indexes were analyzed. The results indicated that with the parameters of furrow opener position was 50 mm, backfill shovel inclined angle was 40°and the depth into the soil of furrow opener was 115 mm, the percent of pass of upright degree was higher than 93%, the coefficient of spacing deviation was less than 12%. The optimized parameters can meet the need of corn transplanting mechanical performance and provide basis for further research.
