　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】近日，中國(guó)熱科院橡膠所機(jī)械裝備與自動(dòng)化團(tuán)隊(duì)在橡膠樹機(jī)械割膠策略優(yōu)化方面取得新進(jìn)展。該研究闡述了一種新的橡膠樹機(jī)械割膠裝置，解析了橡膠樹割膠機(jī)械關(guān)鍵切割部件設(shè)計(jì)與割膠農(nóng)藝技術(shù)融合的優(yōu)化策略，為智能割膠裝備的創(chuàng)新研發(fā)提供重要的理論基礎(chǔ)。
 
　　割膠是收獲膠乳的重要途徑，傳統(tǒng)人力割膠技術(shù)專業(yè)性強(qiáng)且難度大，勞動(dòng)強(qiáng)度高，近十年，機(jī)械采膠裝備研發(fā)已成為破解產(chǎn)業(yè)掣肘的重要方向?；谔烊幌鹉z智能化采收“探-策-控”關(guān)鍵技術(shù)的科技攻關(guān)，該研究提出了一種具有立刃刀片和可調(diào)導(dǎo)向器相配合的機(jī)械切割裝置，以手持式割膠機(jī)為試驗(yàn)本體，采用響應(yīng)面法(RSM)和中心組合旋轉(zhuǎn)設(shè)計(jì)(CCRD)優(yōu)化方法，以刀片立刃高度、切削力、割線螺旋角為影響因子，以舊膠線切出率、切割時(shí)間、排膠初速度、平均切割電流為響應(yīng)值，確定了優(yōu)化方案。通過(guò)對(duì)比傳統(tǒng)人力割膠效果，以樹皮厚度、樹皮消耗量、膠乳初速度、切割時(shí)間、灰分含量和割膠深度為評(píng)價(jià)指標(biāo)，初步驗(yàn)證了優(yōu)化后的機(jī)械割膠策略的有效性。本研究提出的橡膠樹機(jī)械割膠策略，有望應(yīng)用于固定式割膠機(jī)、自走式割膠機(jī)器人等相關(guān)產(chǎn)品設(shè)計(jì)中，有助于提高割膠效率，促進(jìn)橡膠產(chǎn)業(yè)采收裝備的智慧化發(fā)展。
 
　　該研究成果以“An optimization study on a novel mechanical rubber tree tapping mechanism and technology”為題發(fā)表在《Forests》上。中國(guó)熱科院橡膠所王玲玲副研究員為該論文的第一作者，橡膠所鄭勇副研究員和信息所黃家健農(nóng)藝師為該論文的共同通訊作者。該研究得到了海南省自然科學(xué)基金高層次人才項(xiàng)目(522RC788)和國(guó)家重點(diǎn)研發(fā)計(jì)劃項(xiàng)目(2020YFD1000602)的共同資助。
