摘　　要：　分析了目前应用较多的几种刮种器的不足之处;通过对种子吸附在吸种孔上的受力分析,找出了影响刮种可靠性的因素(刮种装置的刚度);在此基础上设计了一种结构简单、性能良好的橡胶条式刮种器;在气吸式精量播种机高速作业(作业速度达到4～5km·h-1)的情况下,橡胶条刮种器能够将重播率控制在10%以内,而且对空穴率也能够控制在2%以下。This paper analyses the shortcoming of several kinds of scraper that offen have been used recently, and by means of analysing the forces acting on several seeds which are sucked on one picker hole,we found the factors that affected the seed scrape performance(the rigidity of scraper).Based on this, we designed the rubber bar scraper. The structure of this kind of scraper is simple. Our experiments in field proved that this scraper can work well:(under the condition the work speed is at 4-5 km·h^(-1)) The rubber bar scraper can control the resowing rate is below 10% and the unsowing rate is below 2%.
