钉轮组合式排种装置结构与性能分析

排种器是播种机的核心部件,是决定播种机特性和工作性能的主要因素。钉轮组合式排种器是用于免耕播种机的一种新型条播排种器,其具有排种通用性好、播量调节方便,特别是对小粒种子(如苜蓿、谷子、油菜籽等)小播量时精度高等优点。为此,从结构和工作原理入手,结合作物种子几何尺寸,对钉轮组合式排种器的大钉轮钉齿间隙尺寸进行了理论分析,为今后钉轮组合式排种器排种性能开展试验研究及其结构优化提供了理论指导。

Analysis on the Structure and Performance of the Combined Studded Feed Roller Seed Metering Device

The seed-metering device as the core component of planter is the main factors to determine the characteristics and performance of planter.The combined studded feed roller seed metering device is a new metering device used for sowing in lines of no-tillage planter,which has many advantages such as good universality and convenient adjustment of application rate,and high precision of sowing minimum-seeding especially for the small seeds(such as alfalfa,millet and rapeseed).In this paper,the size of big studded feed roller nail tooth gap of the combined studded feed roller seed Metering device had been analyzed in theory from the structure and the work principle,which combining the size of crop seeds,provided theoretical direction for the further study and optimum structure on the combined studded feed roller seed metering device of no-tillage drill for the future.
