摘　　要：针对传统花生联合收获机刚性夹持链夹持损失率偏高的问题,提出了三夹持带柔性夹持技术,并设计了三夹持带夹持输送装置。通过试验台试验确定了带型、带距、带速等参数,并通过与刚性夹持链的田间对比试验,对拉断落果率、夹持喂入率、夹断率、去土率、掉株率、掉果率等试验指标进行了综合评价。试验结果表明,三夹持带柔性夹持输送方式损失率较低。In traditional peanut combine harvest,loss rate of peanut in the process of chain rigidity clamping is rather high. Thus,three-belt clamping technology was proposed. Making use of general three-belt flexible clamping cushion to peanut,general three-belt clamping feeding device was developed. Belt type,belt distance,belt speed and so on were determined through bench tests. And according to the field comparative tests to chain rigidity clamping feeding mode,comprehensive evaluation was done on testing index,such as pulling-down peanut drop rate,clamping feeding rate,clamping breaking rate,soil removing rate,straw falling rate,peanut falling rate and so on. The results showed that loss rate of the general three-belt clamping feeding mode was rather low and more suitable for current Chinese peanut harvest situation.
