滑道分钵轮式栽植器的试验研究

Experimental Study on a Slideway Parting-bowl-wheel Transplanter

对滑道分钵轮式栽植器的结构、工作过程、钵体在滑道不同部位的运动状态和受力情况进行了分析 ,并对该栽植器的工作稳定性和立苗率进行了正交和单因素的试验分析。分别找出了影响栽植器工作稳定性和立苗率的因素及其最佳值。

The structure and the working process of a slideway parting-bowl-wheel transplanter, and the movement and the forced states of a bowl on the slideway were analyzed in this work. The working stability and the seedling-standing ratio of this transplanter were tested and analyzed by the orthogonality and single-factor tests methods. The order of the influencing factors for the working stability of the transplanter is moisture content (M), earthen bowl side shape (S), and slideway obliquity (α). The best values of the three influencing factors on the working stability were found out. The order of the influencing factors for the seedling-standing ratio of the transplanter is height of throwing earthen bowl (H), advancing velocity of the unit (v), and slideway obliquity (α) for testing with covering. That for testing without covering is height of throwing earthen bowl (H), slideway obliquity (a), and advancing velocity of the unit (v). The best values of the three influencing factors on the seedling-standing ratio were also found out.
