为了减少油菜联合收割机割台切割力,降低油菜切割损失,该文针对切割油菜茎秆切割力的主要影响因素切割方式、茎秆切割位置、切割刀片形式和切割速度在自制切割试验台上进行了单因素和多因素切割力测试试验.单因素试验结果表明:锯齿形刀的切割力比光刀的切割力要小;切割方式以滑切最省力;切割速度和切割位置对切割力影响最大,表现为切割速度越大,茎秆位置离地面高度越高,其切割力越小.多因素试验表明:在油菜茎秆离地高度400 mm处,采用锯齿形刀片滑切时切割力最小.研究结果为设计工作效益高、性能可靠的切割机构提供了理论依据.

In order to minimize the cutting force for rape stem of combine harvester cutting blades and reduce cutting loss, single factor and multi-factor experiments were carried out on the main influencing factors of cutting forces for rape stem using the self-made cutting test-bed. The main factors included cutting mode, cutting position on the rape stem, cutting blade pattern and cutting velocity. The results of single factor experiments showed that the cutting forces of serrated blade were smaller than those of slippery blade. Sliding cutting was the more labor-saving way in the cutting modes. Cutt...
