1．垂直圓盤氣吸排種器的工作原理

垂直圓盤(pan)(pan)氣吸式排(pai)種(zhong)(zhong)器(qi)(qi)(qi)的(de)氣吸室與(yu)風(feng)機(ji)進風(feng)口相連，排(pai)種(zhong)(zhong)盤(pan)(pan)的(de)一(yi)側為氣吸室的(de)負(fu)壓(ya)(ya)道，另一(yi)側為充種(zhong)(zhong)區(qu)(qu)。當高(gao)速旋轉(zhuan)的(de)風(feng)機(ji)產生(sheng)負(fu)壓(ya)(ya)時，地輪帶動(dong)排(pai)種(zhong)(zhong)盤(pan)(pan)轉(zhuan)動(dong)。當排(pai)種(zhong)(zhong)盤(pan)(pan)上(shang)(shang)的(de)排(pai)種(zhong)(zhong)孔(kong)轉(zhuan)到種(zhong)(zhong)子(zi)(zi)室充種(zhong)(zhong)區(qu)(qu)時，種(zhong)(zhong)子(zi)(zi)室與(yu)大氣相通，此時種(zhong)(zhong)子(zi)(zi)被吸附(fu)在(zai)(zai)排(pai)種(zhong)(zhong)孔(kong)上(shang)(shang)。當排(pai)種(zhong)(zhong)盤(pan)(pan)轉(zhuan)到投(tou)種(zhong)(zhong)區(qu)(qu)時，負(fu)壓(ya)(ya)消失，種(zhong)(zhong)子(zi)(zi)在(zai)(zai)重力(li)作(zuo)用下落入開(kai)溝(gou)器(qi)(qi)(qi)開(kai)好的(de)溝(gou)內。排(pai)種(zhong)(zhong)器(qi)(qi)(qi)上(shang)(shang)設(she)有鋸齒式刮種(zhong)(zhong)器(qi)(qi)(qi)，可以刮去多余的(de)種(zhong)(zhong)子(zi)(zi)，滿足(zu)精量播種(zhong)(zhong)的(de)要求。

2．排種量不穩定的影響因素

造成排(pai)(pai)(pai)種量不(bu)穩定的原因主要有(you)(you)以(yi)下幾點：一(yi)是(shi)吸(xi)(xi)(xi)氣管路出(chu)現(xian)問題(ti)(ti)。吸(xi)(xi)(xi)氣管路有(you)(you)漏(lou)(lou)氣的地方(fang)，如漏(lou)(lou)洞(dong)、接頭(tou)松動、裂紋等(deng)，導(dao)致(zhi)(zhi)(zhi)氣壓下降，吸(xi)(xi)(xi)力(li)(li)減小，一(yi)部分或(huo)(huo)全部漏(lou)(lou)播(bo)，主要表(biao)現(xian)為個(ge)別(bie)壟行播(bo)量減少(shao)或(huo)(huo)漏(lou)(lou)播(bo)。二是(shi)膠管質(zhi)量出(chu)現(xian)問題(ti)(ti)。吸(xi)(xi)(xi)氣膠管質(zhi)量差、老化、破損、漏(lou)(lou)洞(dong)或(huo)(huo)產(chan)(chan)生脫離層(ceng)而使(shi)氣流阻(zu)力(li)(li)加大，氣壓降低(di)，難以(yi)吸(xi)(xi)(xi)附(fu)種子，出(chu)現(xian)排(pai)(pai)(pai)種量減少(shao)或(huo)(huo)漏(lou)(lou)播(bo)現(xian)象(xiang)。三(san)是(shi)風(feng)機(ji)(ji)(ji)兩側軸承(cheng)出(chu)現(xian)問題(ti)(ti)。磨損嚴(yan)重、年久(jiu)失修或(huo)(huo)長期缺油，導(dao)致(zhi)(zhi)(zhi)阻(zu)力(li)(li)增大、轉(zhuan)速下降、氣壓不(bu)足(zu)(zu)(zu)，表(biao)現(xian)為整機(ji)(ji)(ji)播(bo)量不(bu)足(zu)(zu)(zu)或(huo)(huo)完(wan)全漏(lou)(lou)播(bo)。四是(shi)風(feng)機(ji)(ji)(ji)轉(zhuan)速出(chu)現(xian)問題(ti)(ti)。風(feng)機(ji)(ji)(ji)轉(zhuan)速不(bu)足(zu)(zu)(zu)，吸(xi)(xi)(xi)力(li)(li)不(bu)夠(gou)。主機(ji)(ji)(ji)轉(zhuan)速降低(di)、動力(li)(li)輸出(chu)軸出(chu)現(xian)故障(zhang)或(huo)(huo)三(san)角傳動帶陳舊、磨損嚴(yan)重、拉長、松弦(xian)等(deng)，都會導(dao)致(zhi)(zhi)(zhi)風(feng)機(ji)(ji)(ji)轉(zhuan)速下降。五是(shi)排(pai)(pai)(pai)種盤出(chu)現(xian)問題(ti)(ti)。排(pai)(pai)(pai)種盤因保(bao)管、安裝(zhuang)不(bu)當而產(chan)(chan)生變形、銹蝕或(huo)(huo)種室變形等(deng)使(shi)排(pai)(pai)(pai)種盤與(yu)種室密封不(bu)好，產(chan)(chan)生漏(lou)(lou)氣，導(dao)致(zhi)(zhi)(zhi)種子吸(xi)(xi)(xi)力(li)(li)不(bu)足(zu)(zu)(zu)；種子里混有(you)(you)雜(za)物(wu)，將排(pai)(pai)(pai)種盤孔眼(yan)堵死(si)，造成漏(lou)(lou)播(bo)種；排(pai)(pai)(pai)種盤型(xing)號不(bu)當，孔眼(yan)過小，吸(xi)(xi)(xi)力(li)(li)不(bu)足(zu)(zu)(zu)，導(dao)致(zhi)(zhi)(zhi)無(wu)法吸(xi)(xi)(xi)附(fu)種子或(huo)(huo)吸(xi)(xi)(xi)量少(shao)，進(jin)而產(chan)(chan)生漏(lou)(lou)播(bo)或(huo)(huo)播(bo)量不(bu)足(zu)(zu)(zu)現(xian)象(xiang)。

3．提高排種器精確性的措施

發現(xian)漏(lou)播現(xian)象，應(ying)(ying)立即停車熄火，將(jiang)播種機(ji)(ji)落(luo)地檢查原因。若(ruo)接(jie)頭連接(jie)不(bu)牢，可重新接(jie)牢；有較小(xiao)孔眼或裂紋的可用膠帶貼(tie)補(bu)，孔眼過大或裂紋過長應(ying)(ying)更(geng)換新管；輸氣管內壁脫層阻力大應(ying)(ying)更(geng)換新管。排種盤(pan)或排種室變形可試校，校平后(hou)仍然(ran)漏(lou)氣應(ying)(ying)更(geng)換新品；發動(dong)(dong)機(ji)(ji)轉速正常而風機(ji)(ji)風量不(bu)足，要檢查風機(ji)(ji)軸(zhou)(zhou)承，如有曠動(dong)(dong)、異聲等應(ying)(ying)更(geng)換軸(zhou)(zhou)承。

如(ru)果播(bo)(bo)種(zhong)機完(wan)全(quan)(quan)不(bu)播(bo)(bo)種(zhong)，主要(yao)(yao)是(shi)磨損(sun)嚴(yan)重(zhong)(zhong)或運(yun)輸(shu)(shu)、保管不(bu)當造成傳動(dong)件(jian)變形(xing)，如(ru)方(fang)軸、軸套、傘(san)齒輪、排種(zhong)器等嚴(yan)重(zhong)(zhong)磨損(sun)、變形(xing)，導(dao)致風(feng)速和風(feng)量(liang)不(bu)足而(er)完(wan)全(quan)(quan)不(bu)播(bo)(bo)種(zhong)。此(ci)時(shi)，要(yao)(yao)全(quan)(quan)面(mian)檢(jian)修播(bo)(bo)種(zhong)機，如(ru)方(fang)軸要(yao)(yao)校直(zhi)，配合松曠的可(ke)加墊(dian)片消(xiao)除(chu)間隙，磨損(sun)嚴(yan)重(zhong)(zhong)的要(yao)(yao)焊補后(hou)(hou)(hou)磨平。傘(san)齒輪磨損(sun)過大的要(yao)(yao)成對更(geng)換(huan)(huan)，磨損(sun)不(bu)太(tai)嚴(yan)重(zhong)(zhong)的可(ke)在內孔(kong)加墊(dian)片消(xiao)除(chu)間隙。方(fang)向節可(ke)用推(tui)焊法(fa)填補磨痕，然(ran)后(hou)(hou)(hou)車平表面(mian)。裝(zhuang)復后(hou)(hou)(hou)應轉動(dong)靈活。排種(zhong)器要(yao)(yao)更(geng)換(huan)(huan)。維護時(shi)要(yao)(yao)注意(yi)方(fang)軸套和軸、傘(san)齒輪的潤滑，以減緩磨損(sun)。運(yun)輸(shu)(shu)中要(yao)(yao)防止(zhi)碰(peng)撞。

為(wei)了提高排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)精確(que)性，還需要(yao)做到(dao)以(yi)下(xia)幾(ji)點(dian)：一是(shi)(shi)選(xuan)擇(ze)適(shi)當的(de)(de)(de)排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)孔(kong)(kong)(kong)(kong)。排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)孔(kong)(kong)(kong)(kong)的(de)(de)(de)大小影(ying)(ying)響種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)能(neng)否準確(que)而(er)(er)穩(wen)(wen)定(ding)地(di)被(bei)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)在排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)盤(pan)表(biao)(biao)面(mian)。試驗(yan)證明，較佳(jia)的(de)(de)(de)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)孔(kong)(kong)(kong)(kong)直(zhi)徑為(wei)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)直(zhi)徑的(de)(de)(de)0.5～0.7倍(bei)。二是(shi)(shi)選(xuan)擇(ze)適(shi)宜(yi)的(de)(de)(de)作(zuo)(zuo)業(ye)速(su)度。作(zuo)(zuo)業(ye)速(su)度可(ke)改變種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)線速(su)度，增大種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)慣性，從而(er)(er)對(dui)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)力產生影(ying)(ying)響。作(zuo)(zuo)業(ye)速(su)度越大，種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)力越大。三(san)是(shi)(shi)適(shi)宜(yi)的(de)(de)(de)氣(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)真(zhen)(zhen)(zhen)(zhen)空(kong)度。氣(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)真(zhen)(zhen)(zhen)(zhen)空(kong)腔(qiang)(qiang)是(shi)(shi)由氣(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)和排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)盤(pan)構成，真(zhen)(zhen)(zhen)(zhen)空(kong)度直(zhi)接(jie)關系到(dao)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)能(neng)否吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)在排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)盤(pan)表(biao)(biao)面(mian)，它(ta)與(yu)重力、種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)慣性力、摩(mo)擦力、離心力共同(tong)構成一個動(dong)態平(ping)衡，確(que)保(bao)氣(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)正(zheng)常(chang)工(gong)(gong)作(zuo)(zuo)。為(wei)了保(bao)持氣(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)工(gong)(gong)作(zuo)(zuo)腔(qiang)(qiang)有穩(wen)(wen)定(ding)的(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)度，排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)盤(pan)周邊的(de)(de)(de)泄(xie)漏面(mian)積和排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)盤(pan)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)孔(kong)(kong)(kong)(kong)面(mian)積總和與(yu)氣(qi)(qi)流(liu)管(guan)路截面(mian)之間(jian)有一定(ding)的(de)(de)(de)比(bi)例關系，當吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)孔(kong)(kong)(kong)(kong)面(mian)積總和超過(guo)(guo)一定(ding)數(shu)值時，氣(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)將不(bu)能(neng)形成足夠的(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)度，導(dao)致(zhi)機具無法正(zheng)常(chang)工(gong)(gong)作(zuo)(zuo)。當吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)孔(kong)(kong)(kong)(kong)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)到(dao)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)后真(zhen)(zhen)(zhen)(zhen)空(kong)度會(hui)(hui)上(shang)(shang)升(sheng)，而(er)(er)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)孔(kong)(kong)(kong)(kong)上(shang)(shang)沒有吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)滿(man)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)，會(hui)(hui)使氣(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)的(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)度大大下(xia)降(jiang)，使吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)更(geng)困難。通(tong)過(guo)(guo)密封氣(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)管(guan)接(jie)頭、精密加工(gong)(gong)排(pai)(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)盤(pan)和氣(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)結合(he)面(mian)、選(xuan)擇(ze)適(shi)當的(de)(de)(de)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)孔(kong)(kong)(kong)(kong)等措施，可(ke)以(yi)大大提高種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)能(neng)力。四(si)是(shi)(shi)使用刮種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)裝置。刮種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)片的(de)(de)(de)作(zuo)(zuo)用是(shi)(shi)將吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)上(shang)(shang)來的(de)(de)(de)多余種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)碰撞掉，從而(er)(er)使吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)上(shang)(shang)的(de)(de)(de)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)加穩(wen)(wen)定(ding)，進而(er)(er
