【
農(nóng)機網(wǎng) 科技創(chuàng)新】 本技術(shù)指導意見適用于玉米機械化摘穗/籽粒收獲作業(yè)。在一定區(qū)域內(nèi),玉米品種及種植模式、行距應盡量規(guī)范一致,作物及地塊條件適于機械化收獲。應選擇與作物種植行距、成熟期、適宜收獲方式對應的玉米
收獲機并提前檢查調(diào)試好機具,確認適宜收獲期,執(zhí)行玉米機收作業(yè)質(zhì)量標準和操作規(guī)程,努力減少收獲環(huán)節(jié)的落穗、落粒、破碎等損失。
一、作業(yè)前機具準備
玉米聯(lián)合收獲機作業(yè)前要做好充分的保養(yǎng)與調(diào)試工作,使機具達到最佳工作狀態(tài),預防和減少作業(yè)故障的發(fā)生,提高收獲質(zhì)量和效率。
(一)機具檢查
作業(yè)季節(jié)前要依據(jù)產(chǎn)品使用說明書對玉米收獲機進行一次全面檢查與保養(yǎng),確保機具在整個收獲期能正常工作。經(jīng)重新拆裝、保養(yǎng)或修理后的玉米收獲機要認真做好試運轉(zhuǎn),仔細檢查行走、轉(zhuǎn)向、割臺、輸送、剝皮、脫粒、清選、卸糧等機構(gòu)的運轉(zhuǎn)、傳動、間隙等情況。作業(yè)前,要檢查各操縱裝置功能是否正常;檢查各部位軸承及軸上高速轉(zhuǎn)動件(如莖稈切碎裝置,中間軸)安裝情況;
離合器、制動踏板自由行程是否適當;燃油、
發(fā)動機機油、潤滑油、冷卻液是否適量;儀表盤各指示是否正常;輪胎氣壓是否正常;V型帶、鏈條、張緊輪等是否松動或損傷,運動是否靈活可靠;檢查和調(diào)整各傳動皮帶的張緊度,防止作業(yè)時皮帶打滑;重要部位螺栓、螺母有無松動;有無漏水、滲油等現(xiàn)象;所有防護罩是否緊固,檢查窗、密封件、金屬擋板等部位是否閉合、密封完全。備足備好田間作業(yè)常用工具、零配件、易損零配件等,以便出現(xiàn)故障時能夠及時排除。進行空載試運轉(zhuǎn),檢查液壓系統(tǒng)工作情況,液壓管路和液壓件的密封情況;檢查軸承是否過熱及皮帶、鏈條的傳動情況,以及各連接部件的緊固情況。
(二)試收
正式收獲前,選擇有代表性的地塊進行試收,對機器調(diào)試后的技術(shù)狀態(tài)進行一次全面的現(xiàn)場檢查,根據(jù)實際的作業(yè)效果和農(nóng)戶要求進行必要調(diào)整。首先應根據(jù)種植行距選擇匹配的收獲機割臺,種植行距與割臺割行中心之間的差別在±5厘米以內(nèi)(寬幅多行收獲時應保證種植行距與割行中心距差別在±3厘米以內(nèi)),超過此限則應更換割臺適宜的收獲機。收獲機進入田間后,接合動力檔,使機器緩慢運轉(zhuǎn)。確認無異常后,將割臺液壓操縱手柄下壓,降落割臺到合適位置(使摘穗板或摘穗輥前部位于玉米結(jié)穗位下部30—50厘米處),對準玉米行正中,緩慢結(jié)合主離合,使各機構(gòu)運轉(zhuǎn),若無異常方可使發(fā)動機轉(zhuǎn)速提升至額定轉(zhuǎn)速;待各機構(gòu)運轉(zhuǎn)平穩(wěn)后,再掛低速擋前進。首先應采用收獲機使用說明書推薦的參數(shù)設置進行試收,采取正常作業(yè)速度試收30米左右停機,并倒車至起始位置,檢查各位置果穗、籽粒損失、破碎、含雜等情況,確認有無漏割、堵塞等異常情況。
檢查損失時,應明確損失類型和發(fā)生原因。損失區(qū)域由籽粒(果穗)相對于聯(lián)合收獲機的位置而定,收獲時損失一般包含收割前損失、收獲機損失,收獲機損失一般又分為割臺損失、脫粒損失、清選損失、苞葉夾帶籽粒損失等。應明確收獲損失的種類,然后進行針對性調(diào)整。收獲前損失一般由天氣、病蟲害或其他不利因素造成,這部分損失需要通過品種、田間管理等進行調(diào)控。為了減少機械收獲損失,應對摘穗輥(或拉莖輥、摘穗板)、輸送、剝皮、脫粒、清選等機構(gòu)視情況進行必要調(diào)整。調(diào)整后再進行試收檢測,直至達到質(zhì)量標準為止。試收過程中,應注意觀察、傾聽機器工作狀況,發(fā)現(xiàn)異常及時排除。
二、確定適宜收獲期和收獲方式
玉米適期收獲可增加粒重、減少損失、提高產(chǎn)量和品質(zhì),過早或過晚收獲將對玉米的產(chǎn)量和品質(zhì)產(chǎn)生不利影響。玉米成熟的標志是植株的中、下部葉片變黃,基部葉片干枯,果穗變黃,苞葉干枯呈黃白色而松散,籽粒脫水變硬乳線消失,微干縮凹陷,籽?;?胚下端)出現(xiàn)黑帽層,并呈現(xiàn)出品種固有的色澤。玉米收獲適期因品種、播期及生產(chǎn)目的而異。
果穗收獲:對種植中晚熟品種和晚播晚熟的地塊,玉米籽粒含水率一般在25%以上時,應采取機械摘穗、曬場晾棒或整穗烘干的收獲方式,待果穗籽粒含水率降至25%以下或東北地區(qū)白天室外氣溫降至-10℃時,再用機械脫粒。
籽粒直收:對種植早熟品種的地塊,當籽粒含水率降至25%以下或東北地區(qū)白天室外氣溫降至-10℃時,可利用玉米籽粒聯(lián)合收獲機直接進行脫粒收獲,減少晾曬再脫粒成本。
要根據(jù)當時的天氣情況、品種特性和栽培條件確定適宜收獲期,合理安排收獲順序,做到因地制宜、適時搶收,確保顆粒歸倉。如遇雨季迫近,或急需搶種下茬作物,或品種易落粒、折稈、掉穗、穗上發(fā)芽等情況,應適當提前收獲。
三、機收作業(yè)質(zhì)量要求
機收作業(yè)時應嚴格按下表中作業(yè)質(zhì)量標準執(zhí)行。
四、減少收獲損失的措施
(一)檢查作業(yè)田塊
玉米收獲機在進入地塊收獲前,必須先了解地塊的基本情況,包括玉米品種、種植行距、密度、成熟度、產(chǎn)量水平、最低結(jié)穗高度、果穗下垂及莖稈倒伏情況,是否需要人工開道、清理地頭、摘除倒伏玉米等,以便提前制定作業(yè)計劃。對地塊中的溝渠、田埂、通道等予以平整,并將地里水井、電桿拉線、樹樁等不明顯障礙進行標記,以利于安全作業(yè)。根據(jù)地塊大小、形狀,選擇進地和行走路線,以利于運輸車裝車,盡量減少機車的進地次數(shù)。
(二)選擇作業(yè)行走路線
收獲機作業(yè)時保持直線行駛,避免緊急轉(zhuǎn)向。在具體作業(yè)時,機手應根據(jù)地塊實際情況靈活選用。轉(zhuǎn)彎時應停止收割,采用倒車法轉(zhuǎn)彎或兜圈法直角轉(zhuǎn)彎,不要邊收邊轉(zhuǎn)彎,以防分禾器、行走輪等壓倒未收獲的玉米,造成漏割損失,甚至損毀機器。選擇正確的收獲作業(yè)方向,應盡量避免橫向收割,特別是在壟較高的田塊,橫向收割會造成機器大幅度顛簸,進而加大收割損失,甚至造成機具故障。
(三)選擇作業(yè)速度
每種型號收獲機的喂入量是有一定限度的,應根據(jù)玉米收獲機自身喂入量、玉米產(chǎn)量、植株密度、自然高度、干濕程度等因素選擇合理的作業(yè)速度。應保證前進速度與拉莖輥轉(zhuǎn)速、撥禾鏈速度同步,避免不同步造成的割臺落穗損失。通常情況下,開始時先用低速收獲,然后適當提高作業(yè)速度,最后采用正常作業(yè)速度進行收獲,嚴禁為追求效率單方面提升前進速度。收獲中注意觀察摘穗機構(gòu)、剝皮機構(gòu)等是否有堵塞情況。當玉米稠密、植株大、產(chǎn)量高、行距寬窄不一(行距不規(guī)則)、地形起伏不定、早晚及雨后作物濕度大時,應適當降低作業(yè)速度;低速行駛時,不能降低發(fā)動機轉(zhuǎn)速。晴天的中午前后,秸稈干燥,收獲機前進速度可選擇快一些。嚴禁用行走擋進行收獲作業(yè)。
(四)調(diào)整作業(yè)幅寬或收獲行數(shù)
在負荷允許、收割機技術(shù)狀態(tài)完好的情況下,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,影響收獲質(zhì)量,增加損失率、破碎率。當玉米行距寬窄不一,可不必滿割幅作業(yè),避免剮蹭相鄰行莖稈,導致植株倒折及果穗掉落,增加損失。
(五)保持合適的留茬高度
留茬高度應根據(jù)玉米的高度和地塊的平整情況而定,一般留茬高度要小于8厘米,也可高留茬30—40厘米,后期再進行秸稈處理。還田機作業(yè)時,既要保證秸稈粉碎質(zhì)量,又應避免還田刀具太低打土,造成損壞。采用保護性耕作技術(shù)種植的玉米,收獲時留茬高度盡可能控制在15—25厘米,以利于根茬固土,形成“風墻”,起到防風、降低地表風速和阻擋秸稈堆積作用。如安裝滅茬機時,應確保滅茬刀具的入土深度,使滅茬深淺一致,以保證作業(yè)質(zhì)量。定期檢查切割粉碎質(zhì)量和留茬高度,根據(jù)情況隨時調(diào)整。
(六)調(diào)整摘穗輥式摘穗機構(gòu)工作參數(shù)
對于摘穗輥式的摘穗機構(gòu),收獲損失略大,籽粒破碎率偏高,尤其是在轉(zhuǎn)速過低時,果穗與摘穗輥的接觸時間較長,玉米果穗被啃傷的幾率增加;摘穗輥轉(zhuǎn)速較高時,果穗與摘穗輥的碰撞較為劇烈,玉米果穗被啃傷、落粒的幾率增加;因此應合理選擇摘穗輥轉(zhuǎn)速,達到有效降低籽粒破碎率,減少籽粒損失的目的。當摘穗輥的間隙過小時,碾壓和斷莖稈的情況比較嚴重,而且會有較粗大的秸稈不能順利通過而產(chǎn)生堵塞;間隙過大時會啃傷果穗,并導致掉粒損失增加。因此,摘穗輥間隙應根據(jù)玉米性狀特點進行調(diào)整,適應不同粗細的莖稈、果穗,以減少果穗、籽粒的損失。
(七)調(diào)整拉莖輥與摘穗板組合式摘穗機構(gòu)工作參數(shù)
兩個拉莖輥之間及兩塊摘穗板之間的間隙正確與否對減少損失、防止堵塞有很大影響,必須根據(jù)玉米品種、果穗大小、莖稈粗細等情況及時進行調(diào)整。
拉莖輥間隙調(diào)整:拉莖輥間隙是指拉莖輥凸筋與另一拉莖輥凹面外圓之間的間隙,一般取10—17毫米。當莖稈粗、植株密度大,作物含水率高時,間隙應適當大些,反之間隙應小些。間隙過大時拉莖不充分、易堵塞,果穗損失增大;間隙過小,造成咬斷莖稈情況嚴重。
摘穗板工作間隙的調(diào)整:間隙過小,會使大量的玉米葉、莖稈碎段混入玉米果穗中,含雜較大;間隙過大,會造成果穗損傷、籽粒損失增大。應根據(jù)被收玉米性狀特點找到理想的摘穗板工作間隙。
(八)調(diào)整剝皮裝置
對摘穗剝皮型玉米收獲,要調(diào)整適宜壓送器與剝皮輥間距。間距過小時,玉米果穗與剝皮輥的摩擦力大、剝凈率高,但果穗易堵塞,果穗損傷率、落粒率均高。剝皮輥傾角一般取10—12度,傾角過小果穗作用時間長,損傷率、落粒率均高。
(九)調(diào)整脫粒、清選等工作部件
玉米籽粒直收時,建議采用縱軸流脫粒滾筒配合圓桿式凹板結(jié)構(gòu)降低籽粒破碎。脫粒滾筒的轉(zhuǎn)速、脫粒間隙和輸送葉片角度的大小,是影響玉米脫凈率、破碎率的重要因素。在保證破碎率不超標的前提下,可通過適當提高脫粒滾筒的轉(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等措施,提高脫凈率,減少脫粒損失和破碎。
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的前提下,可通過適當減小風扇風量、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)常檢查逐稿器機箱內(nèi)秸稈堵塞情況,及時清理。軸流滾筒可適當減小喂入量和提高滾筒轉(zhuǎn)速,以減少分離損失。
(十)收割過熟作物
玉米過度成熟時,莖稈過干易折斷、果穗易脫落,脫粒后碎莖稈增加易引起分離困難,收獲時應適當降低前行速度,適當調(diào)整清選篩開度,也可安排在早晨或傍晚莖稈韌性較大時收割。
(十一)收割倒伏作物
(1)適宜機具選擇。收獲倒伏玉米宜選用割臺長度長、傾角小、分禾器尖能夠貼地作業(yè)的玉米收獲機。對于有積水或土壤濕度大的地塊,宜選用履帶式收獲機,防止陷車。(2)做好機具調(diào)試改裝。適當調(diào)整或改裝輥式分禾器、鏈式輔助喂入和撥指式喂入等裝置,提高倒伏作物喂入的流暢性;針對籽粒收獲機,應調(diào)整滾筒轉(zhuǎn)速和凹板間隙等,避免過度揉搓,減少高水分籽粒破損。(3)合理確定作業(yè)方式。對于倒伏方向與種植行平行的玉米植株宜采取逆向?qū)π惺斋@方式,并空轉(zhuǎn)返回,有利于扶起倒伏玉米進行收割;對于倒伏方向不一致的玉米植株宜采取往復對行收獲作業(yè)方式。作業(yè)時收獲機分禾器前部應在壟溝內(nèi)貼近地面,并斷開秸稈還田裝置動力或?qū)⒃撗b置提升至最高位置,防止漏收玉米果穗被打碎,方便人工撿拾,減少收獲損失。收獲作業(yè)時應適當降低收獲速度確保正常作業(yè)性能,及時清理割臺,防止倒伏玉米植株不規(guī)則喂入等原因造成的堵塞,影響作業(yè)效果加大作業(yè)損失。
(十二)坡地收獲
采用螺旋式分禾器,或者安裝分離裝置格柵蓋來改善分離效果,提高機器在坡地上的作業(yè)性能。使用割臺時,在不漏割矮穗的前提下,盡可能提高作物的切割高度。
(十三)規(guī)范作業(yè)操作
駕駛員應隨時觀察收獲期作業(yè)狀況,避免發(fā)生分禾器/摘穗機構(gòu)碰撞硬物、漏收、喂入量過大、還田機錘爪打土等異常現(xiàn)象。作業(yè)過程中不得隨意停車,若需停車時,應先停止機器前進,讓收獲機繼續(xù)運轉(zhuǎn)30秒左右,然后再切斷動力,以減少再次啟動時發(fā)生果穗斷裂和籽粒破碎的現(xiàn)象。
五、培訓與監(jiān)督
機手、種植戶和從事收獲質(zhì)量監(jiān)督的鄉(xiāng)鎮(zhèn)農(nóng)機管理人員應經(jīng)過培訓,掌握玉米品種、籽粒含水率、種植模式、收割地形等方面的知識,掌握收獲機的正確使用、維護保養(yǎng)知識以及作業(yè)質(zhì)量標準要求。鼓勵種植戶與機手簽訂收獲作業(yè)損失協(xié)議,農(nóng)機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)其它不合乎要求情形時,要求機手調(diào)整,仍然不合要求的,應更換作業(yè)機器。
