    摘要:

    針對棉花種植行距不統(tǒng)一，導(dǎo)致目前拔棉稈機(jī)適用范圍小、效率低、功能單一等問題，設(shè)計(jì)了具有整理棉稈和分離泥土功能的不對行棉稈拔取收獲臺。簡述了整機(jī)結(jié)構(gòu)和工作原理，并對關(guān)鍵部件進(jìn)行了理論分析、設(shè)計(jì)計(jì)算和選型，對樣機(jī)的主要性能指標(biāo)進(jìn)行了田間測試。試驗(yàn)結(jié)果表明，拔莖輥轉(zhuǎn)速502r/min、整機(jī)前進(jìn)速度0.93m/s時，生產(chǎn)率為0.8hm2/h，拔凈率為97.7%，各項(xiàng)指標(biāo)達(dá)到了設(shè)計(jì)要求。

    Abstract:

    Because of variety of cotton row spacing, there were some problems on cotton stalk pulling machine such as smaller using scope, lower efficiency and function singleness etc. In order to solve the problems，a new cotton stalk pulling head with regardless of row which could rearrange cotton and separate soil was designed. The whole structure and operating principles of the pulling head were introduced, and the critical components were designed by theoretical analysis and calculations. The main performance indexes of a prototype were measured by field tests. The results indicated that production coefficient was0.8hm2/h and pulling rate was 97.7%, when rotational speed of the pulling roller was 502r/min and advance speed was 0.93m/s, and all main parameter indexes reached their design requirements.
