摘要
扎穴机构是深施型液态施肥机重要的工作部件,其性能影响施肥质量、工作可靠性和作业速度。本文阐述了曲柄摇杆式、椭圆齿轮行星系和全椭圆齿轮行星系三种扎穴机构的组成及工作原理,对各自的结构特点、研究方法和存在问题进行比较与分析,并提出进一步研究方向,可为加快深施型液态施肥机的改进设计提供参考。
Pricking hole mechanism is the important working components of deep-fertilization liquid fertilizer applicator, its performances impact fertilization quality, reliability and operating speed. This paper described the compositions and working principle of three kinds pricking hole mechanism, which were respectively based on crank-rocker style, elliptic gear planetary galaxy and the whole elliptic gear planetary galaxy, their structural characteristics, research methods and the existing problems were analyzed and compared, and the further research direction was put forward. The research findings can provide the important reference for accelerating the improvement design on deep-fertilization liquid fertilizer applicator.
