为了寻求减少油菜联合收获机割台损失的途径,设计了一种适应油菜收获的圆盘式切割器.利用摆锤冲击试验机,研究单株油菜的生物物理特性,得出适合油菜切割的高度为200 ～ 400 mm.运用自制的自走式切割试验装置,对影响切割功耗和落粒损失的切割速度、切割高度、刀盘倾角等进行了单冈素和多因素正交试验.单因素试验结果表明,在切割转速700 r/min,切割高度300 mm,刀盘切割倾角10°时,其切割功耗为30.19W,落粒损失为1 162粒.正交试验结果表明,切割转速750 r/min,切割高度250 mm,刀盘切割倾角10°,装置前进速度0.4 m/s,刀片6片为最佳参数,与正交5号试验相近,其切割功耗36.39W,落粒损失895粒.

To reduce losses throu designed. Biophysical property o gh the header on a rape combine harvester, a disc cutter suitable for rape harvest was f single rape was studied using pendulum impact testing machine, the results showed that the suitable height for rape cutting is 200 mm to 400 mm. Based on the self-propelled testing apparatus for rape cutting, the single factor and multi-factor orthogonal experiments were carried out on the factors that influence consuming power and factors influencing seed losses including cutting velocity, cutting hei...
