導(dǎo)讀:在大國“豐景”的背后,中聯(lián)重科農(nóng)機(jī)研發(fā)人員們亦化身追“豐”人,隨著夏收進(jìn)度“摸爬滾打”于麥浪之中。

  【農(nóng)機(jī)網(wǎng) 明星企業(yè)】 每年“三夏”時節(jié),大量收割機(jī)馳騁在我國小麥主產(chǎn)區(qū)廣袤的原野之上,投入到這場與時間競跑的重要農(nóng)事之中。萬千農(nóng)機(jī)手也與收割機(jī)一同啟程,沿著小麥成熟的路線北上收獲,構(gòu)成了獨(dú)特的大國“豐”景。
 
  在大國“豐景”的背后,中聯(lián)重科農(nóng)機(jī)研發(fā)人員們亦化身追“豐”人,隨著夏收進(jìn)度“摸爬滾打”于麥浪之中。與農(nóng)機(jī)手不同的是,他們需要搶趕作物收獲時間節(jié)點(diǎn),在“三夏”期間密集開展上百場機(jī)收試驗(yàn),以高標(biāo)準(zhǔn)打磨農(nóng)機(jī)精品。
 
  時間撥回到6月中旬,山東淄博市烈日當(dāng)空,氣溫飆升至40℃,中聯(lián)重科收割機(jī)減損試驗(yàn)在這火熱的環(huán)境下進(jìn)行著。
 
  一臺TK100MAX收割機(jī)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(jī)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(jī)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(jīng)過稱重、復(fù)篩后,通過檢拾出糠草中籽粒和雜質(zhì)的重量分別計算出機(jī)收損失率、破碎率和含雜率。
 
  機(jī)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(chǎn)量的重要舉措。權(quán)威數(shù)據(jù)顯示,如果全國的小麥機(jī)收損失率平均下降1個百分點(diǎn),就能挽回糧食損失25億斤。為了最大化降低機(jī)收損失率,這些研發(fā)人員們會根據(jù)試驗(yàn)得出的數(shù)據(jù),對收割機(jī)工作裝置轉(zhuǎn)速、撥禾輪角度、脫粒凹板間隙、清選風(fēng)機(jī)風(fēng)量、風(fēng)向等關(guān)鍵參數(shù)進(jìn)行反復(fù)調(diào)試,使之達(dá)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(yàn),我們這款TK100MAX收割機(jī)可以達(dá)到0.2%的損失率。與國家所要求的1.0%損失率標(biāo)準(zhǔn)相比,低了0.8個百分點(diǎn)。”中聯(lián)重科小麥機(jī)技術(shù)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(chǎn)1000斤糧食的標(biāo)準(zhǔn)來測算,每天可為用戶多收約1200-1600斤的糧食。”
 
  對機(jī)收減損的極致追求同樣也體現(xiàn)在對產(chǎn)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(jī)奮戰(zhàn)在各地麥?zhǔn)找痪€,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(chǎn)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(dǎo)向的指引下,研發(fā)人員們于5月初從四川開始田間試驗(yàn),途徑安徽、河南、河北、山東等區(qū)域。他們頂著烈日與收割機(jī)在麥田中“共舞”,通過上百場機(jī)收試驗(yàn)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(fēng)機(jī)風(fēng)量等關(guān)鍵參數(shù)與作業(yè)質(zhì)量的關(guān)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(yàn),他們還對各機(jī)型多種作業(yè)工況的油耗、扭矩、振動等數(shù)據(jù)進(jìn)行采集,對產(chǎn)品進(jìn)行了全面的評價、分析和改進(jìn)。就是在這樣高頻次、高強(qiáng)度的田間試驗(yàn)中,中聯(lián)重科收割機(jī)產(chǎn)品的各項性能不斷邁向新高度。
 
  “在今年三夏期間,我們進(jìn)行了約120場小麥機(jī)收試驗(yàn),總作業(yè)量在4800畝以上,可以說是非常充分地驗(yàn)證了我們的產(chǎn)品在各種工況下的作業(yè)表現(xiàn)。” 項目負(fù)責(zé)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(yàn)過程中暴露出的問題進(jìn)行整理和分析,為下一步產(chǎn)品升級提供了關(guān)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(nóng)機(jī)產(chǎn)品。”
