摘要
本文对地膜覆盖播种机成穴器进行了理论分析和试验研究,确定了成穴器的结构参数和最优结构形式。成穴器的性能试验表明,本文提出的成穴器性能良好,解决了现有成穴器普遍存在的一些问题。特别是侧向开启圆锥形鸭嘴有效地避免了堵土问题,是一种极有前途的新颖部件。
Theoretical analysis and experiment on Accumulative Drop Unit (ADU) have been made to determine its parameters and optimal structure. The performance tests of ADU have showed that performance of ADU presented in this paper is satisfactory and present problems of such unit are solved. Especially, the side-open 'conic duckbill' mounted on the unit effectively presents the soil blocking up problem. Therefore, the unit is a kind of updated working
