摘　　要：阐述了影响辊式摘穗装置工作性能的诸因素和卧辊式玉米摘穗试验台的设计要点。设计中考虑了进行单因素试验和多因素试验中调控各相关工作参数、国产主要玉米收获机卧辊式摘穗辊的装拆以及数据采集等各环节中的技术问题。通过试验分析了辊式摘穗机构在摘穗中对玉米穗啃伤的影响因素,确定了在辊型一定的条件下,摘穗辊转速是主要因素。A device for testing the performance of snapping rolls of corn harvester was researched and developed, and the influencing factors on picking maize-cob were discussed in this paper. In the designing of the tester, the regulating and controlling factors influencing the roller-type picking mechanism were considered. The working factors can be adjusted and controlled in monofactorial tests and multifactorial tests. The snapping rolls of main corn harvester made in China can be installed easily. The affecting factors of the snapping rolls on corn-grain gnawing damage were analyzed by tests. The results show that the rotate speed of the snapping rolls is the key factor on the condition of a certain roller type.
