創(chuàng)新驅(qū)動發(fā)展 邁向科技強國——勇猛機械向國家“十三五”交上完美答卷

導讀：《高含水率玉米單縱軸流籽粒收獲機整機開發(fā)》項目，是基于勇猛機械生產(chǎn)的4YL-6(ZL2150)型自走式玉米聯(lián)合收獲機進行的優(yōu)化和創(chuàng)制。

　　【農(nóng)機網(wǎng) 明星企業(yè)】2016年7月26日中國農(nóng)村技術(shù)開發(fā)中心印發(fā)了國科農(nóng)技字[2016]33號文件，勇猛機械股份有限公司以民營企業(yè)身份正式加入了國家重點研發(fā)計劃“智能農(nóng)機裝備”重點專項的國家隊，這是一份榮譽，更是一份責任。
 
　　公司領(lǐng)導對此項目非常重視，技術(shù)部部長親自帶隊組建研發(fā)專項小組，2016年7月——2021年6月(含延期半年)此項目歷時五年之久，通過小組成員不懈努力，最終向國家交上了完美的答卷。國科農(nóng)技字[2022]15號文件，對此項目綜合績效評價為“優(yōu)秀”。
 
　　《高含水率玉米單縱軸流籽粒收獲機整機開發(fā)》項目，是基于公司生產(chǎn)的4YL-6(ZL2150)型自走式玉米聯(lián)合收獲機進行的優(yōu)化和創(chuàng)制，針對中國各地區(qū)對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，解決了高含水率玉米籽粒低損收獲的國際性技術(shù)難題。國內(nèi)大部分地區(qū)的玉米在收獲季節(jié)的時候均為高濕狀態(tài)，甚至華北地區(qū)為了迎接冬小麥的種植時間，無法等待玉米脫水至20%以下，導致收獲季節(jié)玉米的含水率高達30%以上，相較國外玉米收獲時的含水率均在20%以下，出現(xiàn)部分國外品牌機器“水土不服”現(xiàn)象，無法適應(yīng)國內(nèi)玉米收獲的條件。通過此項目的攻關(guān)，在含水率高達32%的情況下，機器收獲的破碎率低至3.7%，遠優(yōu)于國家標準5%的破碎水平。
 
　　高含水率玉米單縱軸流籽粒收獲機整機開發(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、下篩相向振動平衡技術(shù)研究，以提高振動篩的可靠性與使用壽命；通過研究清選風機結(jié)構(gòu)、材料、轉(zhuǎn)速、出口角度對清選效果的影響，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凹板區(qū)域籽粒的運動軌跡,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；
 
　　通過中國農(nóng)業(yè)大學、中國科學技術(shù)大學及科學院所等教授和專家的共同研究，開發(fā)了自動駕駛系統(tǒng)、玉米穗斷穗在線檢測系統(tǒng)、籽粒破碎率在線檢測系統(tǒng)、籽粒損失在線檢測系統(tǒng)、滾筒轉(zhuǎn)速和凹板間隙自動調(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，該機型技術(shù)達到了國際領(lǐng)先水平。
 
　　此項目的完成受到了中國農(nóng)村技術(shù)開發(fā)中心、行業(yè)內(nèi)專家及領(lǐng)導的認可，機器先后參加專家評審會和國家“十三五”科技創(chuàng)新成就展等，向社會展示機器的先進性和智能性。
 
勇猛機械4YL-6參展國家“十三五”科技創(chuàng)新成就展
 
　　中共中央總書記、國家主席、中央軍委主席習近平2021年10月26日下午在參觀國家“十三五”科技創(chuàng)新成就展時強調(diào)，“十三五”時期，我國科技事業(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。這是在黨中央堅強領(lǐng)導下，全黨全國特別是廣大科技工作者共同奮斗的結(jié)果。當前，我國已經(jīng)開啟全面建設(shè)社會主義現(xiàn)代化國家新征程，科技創(chuàng)新在黨和國家發(fā)展全局中具有十分重要的地位和作用，全國廣大科技工作者要面向世界科技前沿、面向經(jīng)濟主戰(zhàn)場、面向國家重大需求、面向人民生命健康，堅定創(chuàng)新自信，緊抓創(chuàng)新機遇，勇攀科技高峰，破解發(fā)展難題，自覺肩負起光榮歷史使命，加快實現(xiàn)高水平科技自立自強，為建設(shè)世界科技強國、實現(xiàn)中華民族偉大復興作出新的更大貢獻。
 
　　“十三五”項目雖已落幕，但勇猛機械會繼續(xù)秉承“科技提升品質(zhì) 創(chuàng)新引領(lǐng)發(fā)展”的經(jīng)營理念，在打造百年勇猛的道路上砥礪前行，用智能農(nóng)機為智慧農(nóng)業(yè)譜寫新篇章。
