    摘要:

    針對利用現(xiàn)有塑料地膜壟上敷設(shè)裝置鋪設(shè)小麥秸稈纖維地膜時(shí)易出現(xiàn)地膜斷裂和膜邊破損等問題,，設(shè)計(jì)了一種小麥秸稈纖維地膜壟上敷設(shè)裝置,。對小麥秸稈纖維地膜覆膜特性進(jìn)行分析，建立了含有修正系數(shù)的壟上覆膜數(shù)學(xué)模型,，探明了地膜產(chǎn)生斷裂的主要影響因素,；對關(guān)鍵部件進(jìn)行設(shè)計(jì)和分析，確定了側(cè)導(dǎo)向輥,、壓邊覆土鎮(zhèn)壓裝置的關(guān)鍵結(jié)構(gòu)及參數(shù)范圍,；采用三因素三水平正交試驗(yàn)法，以展膜輥與壓邊輪的距離,、側(cè)導(dǎo)向輥傾角,、工作速度為試驗(yàn)因素，以采光面展平度,、采光面機(jī)械破損程度為試驗(yàn)指標(biāo),，進(jìn)行了參數(shù)優(yōu)化試驗(yàn)和驗(yàn)證試驗(yàn)。結(jié)果表明：當(dāng)展膜輥與壓邊輪距離120cm,、側(cè)導(dǎo)向輥傾角30°,、作業(yè)速度3.6km/h時(shí)，采光面展平度97.4%,、采光面機(jī)械破損程度12.6mm/m2,，設(shè)計(jì)的小麥秸稈纖維地膜敷設(shè)裝置滿足煙草栽培壟上覆膜機(jī)械化作業(yè)和農(nóng)藝要求。

    Abstract:

    Focusing on the problems of tearing and folding,，when mulching straw fiber film for tobacco through using plastic-film mulching machines on ridge,，a tobacco mulching device on the ridge with wheat straw fiber film cultivation was designed. The mulching straw fiber film process was analyzed to establish the mathematical model of mulching straw fiber film on the ridge with correction coefficient and the main factors affecting tearing of straw fiber film was proposed，when mulching straw fiber film. The structural parameter range of the key components was analyzed and confirmed and the structural parameter ranges were got, aiming at the guide roller of side of film and the device pressing side of film and mulching and pressing soil on the side of film etc.Three factors three levels orthogonal test was used,，the distance between the roller of flattening film and the roller pressing side of film,，the inclination angle of the guide roller of side of film and working speed were selected as test factors.The outspread degree and rate split by film-covering drill of light-struck film were taken as evaluation indexes.The results showed that the working speed and the distance between the roller of flattening film and the roller pressing side of film had an significant effect on rate split by film-covering drill of light-struck film (0.01＜P＜0.05). The effect of the inclination angle of the guide roller of side of film on the outspread degree was extremely significant (P＜0.01)．The results of verification test were as follows：the working speed was 3.6km/s, the distance between the roller of flattening film and the roller pressing side of film came to be 120cm, the inclination angle of guide roller of side of film reached 30°，such outspread degree was 97.4%,，and rate split by film-covering drill of light-struck film was 12.6mm/m2. The device mulching wheat straw fiber film can achieve agricultural need and mechanization of film mulching machine on the ridge for tobacco cultivation.
