对于半喂入脱粒装置弓齿与穗头的接触次数,已有不少资料进行过关于计算方法的推导。但是,各种因素对接触次数的影响,至今仍缺乏深入细致的研究。因而,加强接触次数各影响因素的研究,揭示其规律性,并与梳刷次数的实际结果相比较,最终便可找出两者之间的联系,对弓齿滚筒的设计将会有实际指导意义。 For the semi-feeding threshing device bow teeth and spike head contact times, there are a lot of information on the derivation of calculation methods. However, the impact of various factors on the number of contacts still lacks thorough and detailed studies. Therefore, to strengthen the study of the factors that affect the contact times and reveal its regularity, and finally compare with the actual results of the brushing times, the design of the bow and pinion drums will be given practical guidance significance.
