　　本技術(shù)指導(dǎo)意見適用于全喂入聯(lián)合收割機(jī)的小麥?zhǔn)斋@作業(yè)。在一定區(qū)域內(nèi)，小麥品種及種植模式應(yīng)盡量規(guī)范一致，作物及田塊條件適于機(jī)械化收獲。機(jī)手應(yīng)提前檢查調(diào)試好機(jī)具，確定適宜收割期，執(zhí)行小麥機(jī)收作業(yè)質(zhì)量標(biāo)準(zhǔn)和操作規(guī)程，努力減少收獲環(huán)節(jié)損失。
 

　　一、作業(yè)前機(jī)具準(zhǔn)備
 

　　開始作業(yè)前要保持機(jī)具良好工作狀態(tài)，預(yù)防和減少作業(yè)故障，提高作業(yè)質(zhì)量和效率。
 

　　(一)機(jī)具檢查
 

　　作業(yè)季節(jié)開始前要依據(jù)產(chǎn)品使用說明書對聯(lián)合收割機(jī)進(jìn)行一次全面檢查與保養(yǎng)，確保機(jī)具在整個(gè)收獲期能正常工作。經(jīng)重新安裝、保養(yǎng)或修理后的小麥聯(lián)合收割機(jī)要認(rèn)真做好試運(yùn)轉(zhuǎn)，先局部后整體，認(rèn)真檢查行走、轉(zhuǎn)向、收割、輸送、脫粒、清選、卸糧等機(jī)構(gòu)的運(yùn)轉(zhuǎn)、傳動、操作、間隙等情況，檢查有無異常響聲和三漏情況，發(fā)現(xiàn)問題及時(shí)解決。要檢查各操縱裝置功能是否正常；離合器、制動踏板自由行程是否適當(dāng)；發(fā)動機(jī)機(jī)油、冷卻液是否適量；儀表板各指示是否正常；輪胎氣壓是否正常；傳動鏈、張緊輪是否松動或損傷，運(yùn)動是否靈活可靠；檢查和調(diào)整各傳動皮帶的張緊度，防止作業(yè)時(shí)皮帶打滑；重要部位螺栓、螺母有無松動；有無漏水、滲漏油現(xiàn)象；割臺、機(jī)架等部件有無變形等。備足備好田間作業(yè)常用工具、零配件、易損零配件及油料等，以便出現(xiàn)故障時(shí)能夠及時(shí)排除。
 

　　(二)試割
 

　　正式開始作業(yè)前要選擇有代表性的地塊進(jìn)行試割。試割作業(yè)行進(jìn)長度以30米左右為宜，根據(jù)作物、田塊的條件確定適合的收割速度，對照作業(yè)質(zhì)量標(biāo)準(zhǔn)仔細(xì)檢查損失、破碎、含雜等情況，有無漏割、堵草、跑糧等異常情況，并以此為依據(jù)對割刀間隙、脫粒間隙、篩子開度和(或)風(fēng)扇風(fēng)量等視情況進(jìn)行必要調(diào)整。調(diào)整后再進(jìn)行試割并檢測，直至達(dá)到質(zhì)量標(biāo)準(zhǔn)和農(nóng)戶要求。作物品種、田塊條件有變化要重新試割和調(diào)試機(jī)具。試割過程中，應(yīng)注意觀察、傾聽機(jī)器工作狀況，發(fā)現(xiàn)異常及時(shí)解決。
 

　　二、確定適宜收獲時(shí)間
 

　　小麥機(jī)收宜在蠟熟末期至完熟初期進(jìn)行，此時(shí)產(chǎn)量最高，品質(zhì)最好。小麥成熟期主要特征：蠟熟中期下部葉片干黃，莖稈有彈性，籽粒轉(zhuǎn)黃色，飽滿而濕潤，籽粒含水率25%-30%。蠟熟末期植株變黃，僅葉鞘莖部略帶綠色，莖稈仍有彈性，籽粒黃色稍硬，內(nèi)含物呈蠟狀，含水率20%-25%。完熟初期葉片枯黃，籽粒變硬，呈品種本色，含水率在20%以下。
 

　　確定收獲時(shí)間，還要根據(jù)當(dāng)時(shí)的天氣情況、品種特性和栽培條件，合理安排收割順序，做到因地制宜、適時(shí)搶收，確保顆粒歸倉。小面積收獲宜在蠟熟末期，大面積收獲宜在蠟熟中期，以使大部分小麥在適收期內(nèi)收獲。留種用的麥田宜在完熟期收獲。如遇雨季迫近，或急需搶種下茬作物，或品種易落粒、折稈、折穗、穗上發(fā)芽等情況，應(yīng)適當(dāng)提前收獲時(shí)間。
 

　　三、機(jī)收作業(yè)質(zhì)量要求
 

　　機(jī)收作業(yè)時(shí)應(yīng)嚴(yán)格按下表中作業(yè)質(zhì)量標(biāo)準(zhǔn)執(zhí)行。
 

　　小麥全喂入聯(lián)合收割機(jī)作業(yè)質(zhì)量標(biāo)準(zhǔn)

　　四、減少機(jī)收環(huán)節(jié)損失的措施
 

　　作業(yè)過程中，應(yīng)選擇適當(dāng)?shù)淖鳂I(yè)參數(shù)，并根據(jù)自然條件和作物條件的不同及時(shí)對機(jī)具進(jìn)行調(diào)整，使聯(lián)合收割機(jī)保持良好的工作狀態(tài)，減少機(jī)收損失，提高作業(yè)質(zhì)量。
 

　　(一)選擇作業(yè)行走路線
 

　　聯(lián)合收割機(jī)作業(yè)一般可采取順時(shí)針向心回轉(zhuǎn)、逆時(shí)針向心回轉(zhuǎn)、梭形收割三種行走方法。在具體作業(yè)時(shí)，機(jī)手應(yīng)根據(jù)地塊實(shí)際情況靈活選用。轉(zhuǎn)彎時(shí)應(yīng)停止收割，將割臺升起，采用倒車法轉(zhuǎn)彎或兜圈法直角轉(zhuǎn)彎，不要邊割邊轉(zhuǎn)彎，以防因分禾器、行走輪或履帶壓倒未割麥子，造成漏割損失。
 

　　(二)選擇作業(yè)速度
 

　　根據(jù)聯(lián)合收割機(jī)自身喂入量、小麥產(chǎn)量、自然高度、干濕程度等因素選擇合理的作業(yè)速度。作業(yè)過程中應(yīng)盡量保持發(fā)動機(jī)在額定轉(zhuǎn)速下運(yùn)轉(zhuǎn)。通常情況下，采用正常作業(yè)速度進(jìn)行收割，盡量避免急加速或急減速。當(dāng)小麥稠密、植株大、產(chǎn)量高、早晚及雨后作物濕度大時(shí)，應(yīng)適當(dāng)降低作業(yè)速度。
 

　　(三)調(diào)整作業(yè)幅寬
 

　　在負(fù)荷允許的情況下，控制好作業(yè)速度，盡量滿幅或接近滿幅工作，保證作物喂入均勻，防止喂入量過大，影響脫粒質(zhì)量。當(dāng)小麥產(chǎn)量高、濕度大或者留茬高度過低時(shí)，以低速作業(yè)仍超載時(shí)，適當(dāng)減小割幅，一般減少到80%，以保證小麥的收割質(zhì)量。
 

　　(四)保持合適的留茬高度
 

　　割茬高度應(yīng)根據(jù)小麥的高度和地塊的平整情況而定，一般以5-15厘米為宜。割茬過高，由于小麥高低不一或機(jī)車過田埂時(shí)割臺上下波動，易造成部分小麥漏割，同時(shí)，撥禾輪的撥禾推禾作用減弱，易造成落地?fù)p失。在保證正常收割的情況下，割茬盡量低些，但最低不得小于5厘米，以免切割泥土，加快切割器磨損。
 

　　(五)調(diào)整撥禾輪速度和位置
 

　　調(diào)整撥禾輪的轉(zhuǎn)速，使撥禾輪線速度為聯(lián)合收割機(jī)前進(jìn)速度的1.1-1.2倍，不宜過高。撥禾輪高低位置應(yīng)使撥禾板作用在被切割作物2/3處為宜，其前后位置應(yīng)視作物密度和倒伏程度而定，當(dāng)作物植株密度大并且倒伏時(shí)，適當(dāng)前移，以增強(qiáng)扶禾能力。撥禾輪轉(zhuǎn)速過高、位置偏高或偏前，都易增加穗頭籽粒脫落，使作業(yè)損失增加。
 

　　(六)調(diào)整脫粒、清選等工作部件
 

　　脫粒滾筒的轉(zhuǎn)速、脫粒間隙和導(dǎo)流板角度的大小，是影響小麥脫凈率、破碎率的重要因素。在保證破碎率不超標(biāo)的前提下，可通過適當(dāng)提高脫粒滾筒的轉(zhuǎn)速，減小滾筒與凹板之間的間隙，正確調(diào)整入口與出口間隙之比(應(yīng)為4∶1)等措施，提高脫凈率，減少脫粒損失。清選損失和含雜率是對立的，調(diào)整中要統(tǒng)籌考慮。在保證含雜率不超標(biāo)的前提下，可通過適當(dāng)減小風(fēng)扇風(fēng)量、調(diào)大篩子的開度及提高尾篩位置等，減少清選損失。作業(yè)中要經(jīng)常檢查逐稿器機(jī)箱內(nèi)秸稈堵塞情況，及時(shí)清理，軸流滾筒可適當(dāng)減小喂入量和提高滾筒轉(zhuǎn)速，以減少分離損失。對于清選結(jié)構(gòu)上有排草擋板的，在含雜、損失較高時(shí)，可通過調(diào)整排草板上下高度減少損失。
 

　　(七)收割倒伏作物
 

　　適當(dāng)降低割茬，以減少漏割；撥禾輪適當(dāng)前移，撥禾彈齒后傾15-30度，或者安裝專用的扶禾器，以增強(qiáng)扶禾作用。倒伏較嚴(yán)重的作物，采取逆倒伏方向收獲、降低作業(yè)速度或減少喂入量等措施。
 

　　(八)收割過熟作物
 

　　小麥過度成熟時(shí)，莖稈過干易折斷、麥粒易脫落，脫粒后碎莖稈增加易引起清選困難，收割時(shí)應(yīng)適當(dāng)調(diào)低撥禾輪轉(zhuǎn)速，防止撥禾輪板擊打麥穗造成掉粒損失，同時(shí)降低作業(yè)速度，適當(dāng)調(diào)整清選篩開度，也可安排在早晨或傍晚莖稈韌性較大時(shí)收割。
 

　　(九)規(guī)范作業(yè)操作
 

　　作業(yè)時(shí)應(yīng)根據(jù)作物品種、高度、產(chǎn)量、成熟程度及秸稈含水率等情況來選擇作業(yè)擋位，用作業(yè)速度、割茬高度及工作幅寬來調(diào)整喂入量，使機(jī)器在額定負(fù)荷下工作，盡量降低夾帶損失，避免發(fā)生堵塞故障。要經(jīng)常檢查凹板篩和清選篩的篩面，防止被泥土或潮濕物堵死造成糧食損失，如有堵塞要及時(shí)清理。
 

　　(十)在線監(jiān)測
 

　　如有條件，可在收割機(jī)上裝配損失率、含雜率、破碎率在線監(jiān)測裝置，駕駛員根據(jù)在線監(jiān)測裝置提示的相關(guān)指標(biāo)、曲線，適時(shí)調(diào)整作業(yè)速度、喂入量、留茬高度等作業(yè)狀態(tài)參數(shù)，得到并保持損失率、含雜率、破碎率較理想的作業(yè)狀態(tài)。
 

　　五、培訓(xùn)與監(jiān)督
 

　　機(jī)手、種植戶和從事收獲質(zhì)量監(jiān)督的鄉(xiāng)鎮(zhèn)農(nóng)機(jī)管理人員應(yīng)經(jīng)過培訓(xùn)，掌握小麥品種、籽粒含水率、種植模式、收割地形等方面的知識，掌握收割機(jī)的正確使用、維護(hù)保養(yǎng)知識以及作業(yè)質(zhì)量標(biāo)準(zhǔn)要求。鼓勵(lì)種植戶與機(jī)手簽訂收獲作業(yè)損失協(xié)議，農(nóng)機(jī)管理人員可通過巡回檢查監(jiān)督作業(yè)損失等情況，并在損失偏大或出現(xiàn)其他不合乎要求情形時(shí)，要求機(jī)手調(diào)整，仍然不合要求的，應(yīng)更換作業(yè)機(jī)器。
