绿豆物理机械特性参数的试验研究
Experimental Study on Physical and Mechanical Properties of Mung Bean
摘要
Abstract
Precision sowing mung beans is one of the key factors to solve our industrial mung bean cultivation techniques behind, lower yield and quality and other issues.The air-suction precision seeding is a method for precision seeding process a very wide application.Therefore, the important characteristic parameters test of mung bean seeds was studied, the average size of generous length were 5.72mm, 4.38mm, 4.42mm, spherical degree is 83.95%, the 1000 grain weight was 86.02g, the porosity is 0.5076, repose angle of 24.33 degrees, and the coefficient of restitution of seed with different material between the angle of sliding friction and the coefficient of friction, collision and floating velocity and drag coefficient were studied.Fill the blank in the research of the important characteristic parameters of mung bean, mung bean seeds to fit and provides an important theoretical basis for the following design requirements of improved air suction precision seeder.关键词
