韭菜培土机设计与试验
Design and Experiment of Leek Planting Machine
摘要
Abstract
According to the needs of agriculture,leek into the dynamic growth period to carry out 2-3 times of soil culti-vation work,leek false stem growing high,soil cultivation height is also increasing,aiming at the existing domestic and foreign soil cultivation machine is easy to damage the stems and leaves of leek,supporting the seedling is difficult,is not suitable for the leek multiple soil cultivation problem,designed a leek soil cultivation machine,after the supporting seed-ling device,the theoretical research of the soil cultivation knife,The working parameters were determined,the discrete element method was used to simulate the soil raising process of leek,and the effects of the operating parameters of the soil raising device on the axial velocity of soil particles and the number of particles on the ridge were analyzed.Data pro-cessing software was used to analyze the field test results,and the optimal combination parameters were obtained,that is,the tool speed was 370r/min,the inner retaining plate expansion Angle was 93°,the outer retaining plate expansion An-gle was 68°,the soil width was 365mm,the soil thickness was 94mm,and the soil cover amount of leek true leaf was 72g.关键词
