辊型和作业速度对玉米收获机摘穗性能的影响

Influence of Snapping Roll Type and Harvesting Speed on 4YWQ Corn Harvester

阐述了玉米联合收获机卧辊式摘穗部件的构造、工作原理和工作参数。试验了摘穗辊辊型和作业速度对摘穗性能的影响。试验结果表明,摘穗辊辊型是影响摘穗性能的主要因素。在正常工作范围内,作业速度对摘穗性能的影响不大。

The structure, working principle and main parameters of the snapping rolls of a full-breadth corn harvester was analyzed theoretically. The effects of the type of the snapping rolls and working speed of the harvester on harvesting performance were examined through field experiments. It was found that the type of the snapping rolls was the main factor affecting the picking performance and the working speed of the harvester had indistinctive effect on the harvesting performance.
