【
農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】 今年以來(lái)，寧夏農(nóng)業(yè)機(jī)械化技術(shù)推廣站聯(lián)合國(guó)家農(nóng)機(jī)裝備創(chuàng)新中心、寧夏新大眾機(jī)械有限公司研發(fā)設(shè)計(jì)了履帶式和輪式馬鈴薯聯(lián)合
收獲機(jī)，試制了2臺(tái)樣機(jī)，近期在南部山區(qū)進(jìn)行試收獲作業(yè)，重點(diǎn)測(cè)試了樣機(jī)穩(wěn)定性、通過(guò)性、割臺(tái)適應(yīng)性、作業(yè)效率、除雜率、傷薯率、損失率與故障率。經(jīng)測(cè)試，2臺(tái)樣機(jī)滿(mǎn)足馬鈴薯聯(lián)合收獲作業(yè)功能，一次作業(yè)可完成馬鈴薯挖掘、低損輸送、篩分除雜、集箱等工序，取得了階段性成果。
一是研發(fā)了適合丘陵山地作業(yè)的履帶式和輪式兩類(lèi)馬鈴薯聯(lián)合收獲機(jī)械，集馬鈴薯挖掘、輸送、除雜、除膜、裝車(chē)等工序，整機(jī)一體化設(shè)計(jì)，優(yōu)勢(shì)互補(bǔ)的兩種產(chǎn)品，突破了馬鈴薯只能常規(guī)分段收獲，收獲周期長(zhǎng)、損失率大，收獲后需大量人工撿拾的瓶頸。
二是研發(fā)的馬鈴薯聯(lián)合收獲機(jī)具備地表挖掘仿形功能，突破了常規(guī)
挖掘機(jī)構(gòu)地表仿形效果不佳、挖掘鏟磨損快的難題。
三是研發(fā)了新型分秧除雜、薯土分離、薯膜分離系統(tǒng)，能有效解決黏重土質(zhì)條件下薯土分離困難、馬鈴薯收獲后含雜率高的難題。
四是研發(fā)了轉(zhuǎn)盤(pán)式抖動(dòng)篩分輸送系統(tǒng)，能有效解決馬鈴薯收獲后破皮率高、輸送系統(tǒng)易卡滯、故障率高的難題。
五是研發(fā)了新型快速收集系統(tǒng)和分秧分膜系統(tǒng)，突破了馬鈴薯挖掘后只能鋪放在地表、覆膜種植的馬鈴薯挖掘后碎膜量大的問(wèn)題。
下一步，該站將根據(jù)測(cè)試情況，對(duì)割臺(tái)仿形機(jī)構(gòu)、柔性抖動(dòng)篩分輸送裝置、安全裝置、除膜裝置等進(jìn)行改進(jìn)，進(jìn)一步優(yōu)化結(jié)構(gòu)設(shè)計(jì)加快熟化并形成定型產(chǎn)品，盡快應(yīng)用到農(nóng)業(yè)生產(chǎn)實(shí)際中，解決目前馬鈴薯產(chǎn)業(yè)發(fā)展的瓶頸問(wèn)題，讓研究成果發(fā)揮最大效益，有效提升寧夏馬鈴薯全程機(jī)械化水平。
