導讀：在大國“豐景”的背后，中聯(lián)重科農機研發(fā)人員們亦化身追“豐”人，隨著夏收進度“摸爬滾打”于麥浪之中。

　　【農機網 明星企業(yè)】 每年“三夏”時節(jié)，大量收割機馳騁在我國小麥主產區(qū)廣袤的原野之上，投入到這場與時間競跑的重要農事之中。萬千農機手也與收割機一同啟程，沿著小麥成熟的路線北上收獲，構成了獨特的大國“豐”景。
 
　　在大國“豐景”的背后，中聯(lián)重科農機研發(fā)人員們亦化身追“豐”人，隨著夏收進度“摸爬滾打”于麥浪之中。與農機手不同的是，他們需要搶趕作物收獲時間節(jié)點，在“三夏”期間密集開展上百場機收試驗，以高標準打磨農機精品。
 
　　時間撥回到6月中旬，山東淄博市烈日當空，氣溫飆升至40℃，中聯(lián)重科收割機減損試驗在這火熱的環(huán)境下進行著。
 
　　一臺TK100MAX收割機在前行駛作業(yè)，數(shù)名研發(fā)人員緊跟其后快速奔跑。大量被粉碎的麥秸稈從收割機尾部噴涌而出，使尾隨的研發(fā)人員從頭到腳沾滿了秸稈碎片。收割機停下后，他們把散落在收集帶上的麥秸和糧倉里的糧食搜集起來，在經過稱重、復篩后，通過檢拾出糠草中籽粒和雜質的重量分別計算出機收損失率、破碎率和含雜率。
 
　　機收減損是近年來國家大力提倡的保障糧食安全、增加糧食產量的重要舉措。權威數(shù)據(jù)顯示，如果全國的小麥機收損失率平均下降1個百分點，就能挽回糧食損失25億斤。為了最大化降低機收損失率，這些研發(fā)人員們會根據(jù)試驗得出的數(shù)據(jù)，對收割機工作裝置轉速、撥禾輪角度、脫粒凹板間隙、清選風機風量、風向等關鍵參數(shù)進行反復調試，使之達成最佳配比，穩(wěn)定保持在最小損失率的工作區(qū)間。
 
　　“通過不斷的試驗，我們這款TK100MAX收割機可以達到0.2%的損失率。與國家所要求的1.0%損失率標準相比，低了0.8個百分點。”中聯(lián)重科小麥機技術專家宋所長表示，“這就意味著，按照每天150-200畝地的作業(yè)量，畝產1000斤糧食的標準來測算，每天可為用戶多收約1200-1600斤的糧食。”
 
　　對機收減損的極致追求同樣也體現(xiàn)在對產品的持續(xù)打磨上。在今年“三夏”期間，中聯(lián)重科“谷王”TK100、TE100系列收割機奮戰(zhàn)在各地麥收一線，以高效、穩(wěn)定的作業(yè)表現(xiàn)獲得諸多用戶好評。但對于研發(fā)人員來說，讓產品更加可靠，為用戶創(chuàng)造更多價值才是他們的追求。
 
　　在以用戶需求為導向的指引下，研發(fā)人員們于5月初從四川開始田間試驗，途徑安徽、河南、河北、山東等區(qū)域。他們頂著烈日與收割機在麥田中“共舞”，通過上百場機收試驗采集工作參數(shù)、喂入量和作業(yè)性能數(shù)據(jù)，描繪出凹板間隙、篩子開度、風機風量等關鍵參數(shù)與作業(yè)質量的關系曲線，以及最佳工作參數(shù)下喂入量與作業(yè)性能曲線。除了性能試驗，他們還對各機型多種作業(yè)工況的油耗、扭矩、振動等數(shù)據(jù)進行采集，對產品進行了全面的評價、分析和改進。就是在這樣高頻次、高強度的田間試驗中，中聯(lián)重科收割機產品的各項性能不斷邁向新高度。
 
　　“在今年三夏期間，我們進行了約120場小麥機收試驗，總作業(yè)量在4800畝以上，可以說是非常充分地驗證了我們的產品在各種工況下的作業(yè)表現(xiàn)。” 項目負責人高所長表示。“我們也采集到了大量作業(yè)數(shù)據(jù)，并對試驗過程中暴露出的問題進行整理和分析，為下一步產品升級提供了關鍵的支撐。我們有十足的信心，為廣大用戶提供更加可靠、更加好用的農機產品。”
