【摘要】 对甜菜链式纸钵苗自动移栽机的链式纸钵苗分离装置主要参数进行了优化试验研究。介绍了分离装置的结构及工作原理;采用二次正交旋转中心组合优化试验方法,以分离率、钵苗损伤率为目标函数,以钵苗引出速度、分离轮与引出轮速比、分离轮倾斜角度为影响因子,对影响分离装置性能的工作和结构参数组合进行了优化试验研究。结果表明:当引出速度78～93mm/s、速比6～7、分离轮倾斜角度为13°时,分离率达95%以上,钵苗损伤率小于6%。为甜菜链式纸钵苗分离装置的设计提供了依据。更多还原

【Abstract】 The chain separator parameters optimization for the pot seedling of sugar beet was optimized.,and the structure and working principle of the separator were introduced.A central composite rotatable orthogonal experimental design of response surface methodology was employed for finding the optimum combination effecting on the separator properties.Three parameters,the guide speed,speed ratio and angle of separating wheel were selected as input variables,and the separation efficiency,the seedling damage were used as response functions.Experimental results indicated that the optimum combination region of the guide speed was 78-93 mm/s,the speed ratio was 6-7 and angle of separating wheel was 13°.Its separation efficiency attained more than 95% and simultaneously the seedling damage was less than 6%.The study provides a foundation for the chain separator on the pot seeding of sugar beet.更多还原
