    摘要:

    針對(duì)半喂入花生聯(lián)合收獲機(jī)摘果輥易纏繞塑料覆膜的問題，設(shè)計(jì)了螺旋刀除膜摘果裝置，并對(duì)其進(jìn)行了結(jié)構(gòu)優(yōu)化與試驗(yàn)分析。基于UG對(duì)螺旋刀片建立高級(jí)仿真模型，由應(yīng)力云圖確定刀片的最佳布置形式；通過試驗(yàn)數(shù)據(jù)的分析與處理，確定了螺旋刀除膜摘果輥?zhàn)罴呀Y(jié)構(gòu)與作業(yè)參數(shù)：間隙為5.3mm，摘果輥轉(zhuǎn)速為326r/min，刀片傾角為43°，優(yōu)化后的螺旋刀花生除膜摘果裝置的覆膜絞碎率為95.66%。

    Abstract:

    For the problem of the picking roller of present half-feeding peanut harvester was easily wrapped in plastic membrane, a kind of peanut removing device used spiral knife was designed. The structure optimization and experiment analysis were also carried out. The helical blade was modeled based on UG software. The best arrangement of the blade was confirmed by stress nephogram. Through the analysis of experimental data and processing, the best structure and operating parameters of the proposed device were got: the clearance was 5.3mm, speed of picking roller was 326r/min, and arranging blade angle was 43°. After optimizing, the breaking membrane rate value reached to 95.66%.
