摘要
把电磁振动排种器等价成2自由度振动系统,结合种子在排种盘上的运动,对电磁振动排种器振动系统进行理论解析,给出了系统运动的数学模型,分析了系统各主要振动参数对排种盘与振动筛运动的影响。结果表明,系统参数d1=0.13～0.23,d2=0.2～0.6,μ=1.5时,系统振动稳定,易获得较大的排种速度,种子不易堵塞。
Based on the electromagnetic vibrated seeding apparatus is modeled as two -grades vibration system and the movement of vibrated riddle, research of the mathematic model of seed movement dynamic system in this paper. It also analyzes the main parameter of the system effect on the main vibration parameters. The results express that the system vibrate level off when the parameters is d1= 0.13 - 0.23, d2 = 0.2 - 0.6,μ = 1.5 . Under the work condition, the vibrated of the system level off , easy to gain the maximum speed of the vibrated seeds, and only few seeds be blocked . All express that the model is correct.
