摘  要：
为了提高导苗管式移栽机栽植作业效果及稳定性,以导苗机构为研究对象,选取连杆杆长、曲柄初始相角和移栽机作业速度为试验因素,钵苗直立率为试验指标,在室内土槽中对研制的2ZDJ-2型钵苗移栽机进行了混合水平均匀试验设计。建立了试验因素与指标间的多元非线性回归模型,并分析了因子效应对试验指标的影响规律。采用Matlab软件对试验取值范围内的因子组合进行了优化求解,并进行了最优因子组合方案重复性验证试验,试验结果表明,曲柄初始相角取70°,连杆杆长取356 mm,作业速度设定280 mm/s时,钵苗直立率升至95.5%,导苗机构作业性能稳定。

摘  要：
In order to further improve the operation effect and stability of transplanter with chute,the guiding seedling mechanism was chosen as the research object,indoor mixed level uniform design experiment was done under the condition that the length of the connecting rod,initial phase angle of crank and velocity of the 2ZDJ-2 seedling transplanter were made as the experiment factors and lodging rate was made as the experiment indicator. Multivariate non-linear regression model between experiment factors and indicator was built by making statistical analysis of the experiment result,and the influence rule of factorial effect on experiment indicator was analyzed. Optimized solution of experiment factor combination was done within the scope of experiment data by using Matlab software,and repeated verification experiment of optimal factors combination was done. Experiment result showed that the guiding mechanism worked well when the initial phase angle of crank was 70°,the length of the connecting rod was 356 mm,and the velocity was 280 mm / s,under this condition,the erectness percentage was up to 95. 5%,and the mechanism worked smoothly.
