摘要
为解决新疆穴盘苗移栽机的取苗机构自动化程度不高的问题,建立穴盘苗移栽机取苗机构的虚拟样机,并使用ADAMS对其进行运动仿真分析。同时,以取苗成功率为性能指标,以基质含水率、抗压力、摩擦角和翻转比为影响因素,进行正交试验。经过仿真分析,设定顶杆的顶出速度范围为1.5～2.3m/s,取苗效果理想。最终确定基质含水率为35,%的穴盘苗,基质抗压力为6N、摩擦角为35°时取苗成功率最高。该研究旨在为自动取苗机构的进一步设计、优化和研制提供理论依据。
To solve Xinjiang plug seedling transplanting seedlings institutions machine check is not high degree of automation,plug seedling transplanting seedlings institutions machine to take a virtual prototype and its movement using ADAMS simulation analysis. Finally,in order to picking success rate as the performance index,the matrix moisture content, pressure resistance,friction angle and turnover ratio of influence factors,orthogonal test. Through simulation analysis,set the top rod ejection velocity is in the range of 1. 5 ～ 2. 3m / s,the seedling ideal effect. Ultimately determine the matrix moisture content of 35% seedlings,matrix anti pressure is 6 N,friction angle of 35 ° seedling fetching the highest success rate. This vaccine mechanism to automatically take a further design,optimization and development to provide a theoretical basis.
