　　【農(nóng)機(jī)網(wǎng) 明星企業(yè)】2016年7月26日中國(guó)農(nóng)村技術(shù)開發(fā)中心印發(fā)了國(guó)科農(nóng)技字[2016]33號(hào)文件，勇猛機(jī)械股份有限公司以民營(yíng)企業(yè)身份正式加入了國(guó)家重點(diǎn)研發(fā)計(jì)劃“智能農(nóng)機(jī)裝備”重點(diǎn)專項(xiàng)的國(guó)家隊(duì)，這是一份榮譽(yù)，更是一份責(zé)任。
 
　　公司領(lǐng)導(dǎo)對(duì)此項(xiàng)目非常重視，技術(shù)部部長(zhǎng)親自帶隊(duì)組建研發(fā)專項(xiàng)小組，2016年7月——2021年6月(含延期半年)此項(xiàng)目歷時(shí)五年之久，通過小組成員不懈努力，最終向國(guó)家交上了完美的答卷。國(guó)科農(nóng)技字[2022]15號(hào)文件，對(duì)此項(xiàng)目綜合績(jī)效評(píng)價(jià)為“優(yōu)秀”。
 
　　《高含水率玉米單縱軸流籽粒收獲機(jī)整機(jī)開發(fā)》項(xiàng)目，是基于公司生產(chǎn)的4YL-6(ZL2150)型自走式玉米聯(lián)合收獲機(jī)進(jìn)行的優(yōu)化和創(chuàng)制，針對(duì)中國(guó)各地區(qū)對(duì)高含水率玉米籽粒收獲的不同需求，形成玉米收獲的全覆蓋體系。研制高含水率玉米單縱軸流籽粒收獲機(jī)，解決了高含水率玉米籽粒低損收獲的國(guó)際性技術(shù)難題。國(guó)內(nèi)大部分地區(qū)的玉米在收獲季節(jié)的時(shí)候均為高濕狀態(tài)，甚至華北地區(qū)為了迎接冬小麥的種植時(shí)間，無法等待玉米脫水至20%以下，導(dǎo)致收獲季節(jié)玉米的含水率高達(dá)30%以上，相較國(guó)外玉米收獲時(shí)的含水率均在20%以下，出現(xiàn)部分國(guó)外品牌機(jī)器“水土不服”現(xiàn)象，無法適應(yīng)國(guó)內(nèi)玉米收獲的條件。通過此項(xiàng)目的攻關(guān)，在含水率高達(dá)32%的情況下，機(jī)器收獲的破碎率低至3.7%，遠(yuǎn)優(yōu)于國(guó)家標(biāo)準(zhǔn)5%的破碎水平。
 
　　高含水率玉米單縱軸流籽粒收獲機(jī)整機(jī)開發(fā)
 
　　(1)單縱軸流高效清選技術(shù)研究；
 
　　通過研發(fā)前、中、后三段分體式調(diào)整的上篩結(jié)構(gòu)，適應(yīng)不同玉米性狀引起的脫粒分離梯度差異，提高清選性能；通過上、下篩相向振動(dòng)平衡技術(shù)研究，以提高振動(dòng)篩的可靠性與使用壽命；通過研究清選風(fēng)機(jī)結(jié)構(gòu)、材料、轉(zhuǎn)速、出口角度對(duì)清選效果的影響，提高篩面上氣流均勻性；集成研制單縱軸流高效清選系統(tǒng)，實(shí)現(xiàn)單縱軸流高效清選。
 
　　(2)單縱軸流低損喂入技術(shù)研究；
 
　　單縱軸流低損喂入技術(shù)主要包括優(yōu)化喂入攪龍的結(jié)構(gòu)與位置；研究過橋輸送方式，過橋與單縱軸流脫粒滾筒的平順交接技術(shù)；優(yōu)化單縱軸流低損喂入收獲臺(tái)與過橋，減少玉米果穗損傷。
 
　　(3)滾筒前端脫出物均布研究；
 
　　通過研究滾筒前端活動(dòng)凹板區(qū)域籽粒的運(yùn)動(dòng)軌跡,解決滾筒前端脫出物分布不均的問題,為后續(xù)的清選提供均勻的物料流。
 
　　(4)車輛智能控制系統(tǒng)研究；
 
　　通過中國(guó)農(nóng)業(yè)大學(xué)、中國(guó)科學(xué)技術(shù)大學(xué)及科學(xué)院所等教授和專家的共同研究，開發(fā)了自動(dòng)駕駛系統(tǒng)、玉米穗斷穗在線檢測(cè)系統(tǒng)、籽粒破碎率在線檢測(cè)系統(tǒng)、籽粒損失在線檢測(cè)系統(tǒng)、滾筒轉(zhuǎn)速和凹板間隙自動(dòng)調(diào)整系統(tǒng)、北斗定位系統(tǒng)等，為車輛的智能控制提供了保證，該機(jī)型技術(shù)達(dá)到了國(guó)際領(lǐng)先水平。
 
　　此項(xiàng)目的完成受到了中國(guó)農(nóng)村技術(shù)開發(fā)中心、行業(yè)內(nèi)專家及領(lǐng)導(dǎo)的認(rèn)可，機(jī)器先后參加專家評(píng)審會(huì)和國(guó)家“十三五”科技創(chuàng)新成就展等，向社會(huì)展示機(jī)器的先進(jìn)性和智能性。
 
勇猛機(jī)械4YL-6參展國(guó)家“十三五”科技創(chuàng)新成就展
 
　　中共中央總書記、國(guó)家主席、中央軍委主席習(xí)近平2021年10月26日下午在參觀國(guó)家“十三五”科技創(chuàng)新成就展時(shí)強(qiáng)調(diào)，“十三五”時(shí)期，我國(guó)科技事業(yè)加快發(fā)展，創(chuàng)新能力大幅提升，在基礎(chǔ)前沿、戰(zhàn)略高技術(shù)、民生科技等領(lǐng)域取得一批重大科技成果。這是在黨中央堅(jiān)強(qiáng)領(lǐng)導(dǎo)下，全黨全國(guó)特別是廣大科技工作者共同奮斗的結(jié)果。當(dāng)前，我國(guó)已經(jīng)開啟全面建設(shè)社會(huì)主義現(xiàn)代化國(guó)家新征程，科技創(chuàng)新在黨和國(guó)家發(fā)展全局中具有十分重要的地位和作用，全國(guó)廣大科技工作者要面向世界科技前沿、面向經(jīng)濟(jì)主戰(zhàn)場(chǎng)、面向國(guó)家重大需求、面向人民生命健康，堅(jiān)定創(chuàng)新自信，緊抓創(chuàng)新機(jī)遇，勇攀科技高峰，破解發(fā)展難題，自覺肩負(fù)起光榮歷史使命，加快實(shí)現(xiàn)高水平科技自立自強(qiáng)，為建設(shè)世界科技強(qiáng)國(guó)、實(shí)現(xiàn)中華民族偉大復(fù)興作出新的更大貢獻(xiàn)。
 
　　“十三五”項(xiàng)目雖已落幕，但勇猛機(jī)械會(huì)繼續(xù)秉承“科技提升品質(zhì) 創(chuàng)新引領(lǐng)發(fā)展”的經(jīng)營(yíng)理念，在打造百年勇猛的道路上砥礪前行，用智能農(nóng)機(jī)為智慧農(nóng)業(yè)譜寫新篇章。
