1．垂直圓盤氣吸排種器的工作原理

垂直圓盤氣吸(xi)式(shi)排(pai)(pai)(pai)(pai)種(zhong)器(qi)(qi)的(de)(de)氣吸(xi)室與風機進風口相(xiang)連，排(pai)(pai)(pai)(pai)種(zhong)盤的(de)(de)一側為氣吸(xi)室的(de)(de)負壓道，另(ling)一側為充(chong)種(zhong)區。當高速旋轉的(de)(de)風機產(chan)生(sheng)負壓時，地輪帶動(dong)排(pai)(pai)(pai)(pai)種(zhong)盤轉動(dong)。當排(pai)(pai)(pai)(pai)種(zhong)盤上的(de)(de)排(pai)(pai)(pai)(pai)種(zhong)孔轉到種(zhong)子(zi)室充(chong)種(zhong)區時，種(zhong)子(zi)室與大氣相(xiang)通，此時種(zhong)子(zi)被吸(xi)附在(zai)排(pai)(pai)(pai)(pai)種(zhong)孔上。當排(pai)(pai)(pai)(pai)種(zhong)盤轉到投種(zhong)區時，負壓消失，種(zhong)子(zi)在(zai)重力作用下落入(ru)開溝(gou)(gou)器(qi)(qi)開好的(de)(de)溝(gou)(gou)內(nei)。排(pai)(pai)(pai)(pai)種(zhong)器(qi)(qi)上設有鋸齒式(shi)刮種(zhong)器(qi)(qi)，可以(yi)刮去多(duo)余的(de)(de)種(zhong)子(zi)，滿足精量播種(zhong)的(de)(de)要(yao)求。

2．排種量不穩定的影響因素

造成排(pai)(pai)(pai)種(zhong)(zhong)量(liang)不(bu)穩定的原因(yin)主(zhu)要有(you)以下(xia)幾點：一是(shi)吸氣(qi)(qi)管(guan)路出(chu)現(xian)(xian)(xian)問題(ti)(ti)。吸氣(qi)(qi)管(guan)路有(you)漏(lou)(lou)氣(qi)(qi)的地(di)方，如漏(lou)(lou)洞、接頭松動、裂紋等，導致氣(qi)(qi)壓下(xia)降，吸力(li)(li)減小(xiao)，一部分(fen)或(huo)(huo)(huo)全部漏(lou)(lou)播(bo)，主(zhu)要表(biao)現(xian)(xian)(xian)為(wei)(wei)個別(bie)壟行播(bo)量(liang)減少(shao)或(huo)(huo)(huo)漏(lou)(lou)播(bo)。二(er)是(shi)膠管(guan)質(zhi)量(liang)出(chu)現(xian)(xian)(xian)問題(ti)(ti)。吸氣(qi)(qi)膠管(guan)質(zhi)量(liang)差、老化、破損、漏(lou)(lou)洞或(huo)(huo)(huo)產生脫(tuo)離(li)層而使氣(qi)(qi)流阻(zu)力(li)(li)加大(da)，氣(qi)(qi)壓降低(di)，難以吸附種(zhong)(zhong)子，出(chu)現(xian)(xian)(xian)排(pai)(pai)(pai)種(zhong)(zhong)量(liang)減少(shao)或(huo)(huo)(huo)漏(lou)(lou)播(bo)現(xian)(xian)(xian)象。三是(shi)風機(ji)兩側軸承出(chu)現(xian)(xian)(xian)問題(ti)(ti)。磨(mo)損嚴重、年久(jiu)失修或(huo)(huo)(huo)長期缺油，導致阻(zu)力(li)(li)增大(da)、轉速(su)(su)(su)下(xia)降、氣(qi)(qi)壓不(bu)足(zu)，表(biao)現(xian)(xian)(xian)為(wei)(wei)整機(ji)播(bo)量(liang)不(bu)足(zu)或(huo)(huo)(huo)完全漏(lou)(lou)播(bo)。四是(shi)風機(ji)轉速(su)(su)(su)出(chu)現(xian)(xian)(xian)問題(ti)(ti)。風機(ji)轉速(su)(su)(su)不(bu)足(zu)，吸力(li)(li)不(bu)夠。主(zhu)機(ji)轉速(su)(su)(su)降低(di)、動力(li)(li)輸出(chu)軸出(chu)現(xian)(xian)(xian)故(gu)障或(huo)(huo)(huo)三角傳動帶陳(chen)舊、磨(mo)損嚴重、拉(la)長、松弦等，都會導致風機(ji)轉速(su)(su)(su)下(xia)降。五是(shi)排(pai)(pai)(pai)種(zhong)(zhong)盤(pan)(pan)出(chu)現(xian)(xian)(xian)問題(ti)(ti)。排(pai)(pai)(pai)種(zhong)(zhong)盤(pan)(pan)因(yin)保管(guan)、安裝不(bu)當而產生變形、銹蝕或(huo)(huo)(huo)種(zhong)(zhong)室(shi)變形等使排(pai)(pai)(pai)種(zhong)(zhong)盤(pan)(pan)與種(zhong)(zhong)室(shi)密封不(bu)好，產生漏(lou)(lou)氣(qi)(qi)，導致種(zhong)(zhong)子吸力(li)(li)不(bu)足(zu)；種(zhong)(zhong)子里(li)混(hun)有(you)雜物，將(jiang)排(pai)(pai)(pai)種(zhong)(zhong)盤(pan)(pan)孔眼(yan)堵死(si)，造成漏(lou)(lou)播(bo)種(zhong)(zhong)；排(pai)(pai)(pai)種(zhong)(zhong)盤(pan)(pan)型號(hao)不(bu)當，孔眼(yan)過小(xiao)，吸力(li)(li)不(bu)足(zu)，導致無(wu)法(fa)吸附種(zhong)(zhong)子或(huo)(huo)(huo)吸量(liang)少(shao)，進而產生漏(lou)(lou)播(bo)或(huo)(huo)(huo)播(bo)量(liang)不(bu)足(zu)現(xian)(xian)(xian)象。

3．提高排種器精確性的措施

發現(xian)漏(lou)播現(xian)象，應立即停車(che)熄火(huo)，將播種機落地檢(jian)(jian)查原因。若接頭連接不(bu)牢，可(ke)重新(xin)接牢；有較小孔(kong)眼或(huo)(huo)裂(lie)紋的可(ke)用膠帶貼補，孔(kong)眼過大或(huo)(huo)裂(lie)紋過長(chang)應更(geng)換(huan)(huan)新(xin)管；輸氣管內壁(bi)脫層阻力大應更(geng)換(huan)(huan)新(xin)管。排種盤或(huo)(huo)排種室變形(xing)可(ke)試校(xiao)(xiao)，校(xiao)(xiao)平后仍(reng)然(ran)漏(lou)氣應更(geng)換(huan)(huan)新(xin)品；發動(dong)機轉速正(zheng)常而風(feng)機風(feng)量不(bu)足(zu)，要檢(jian)(jian)查風(feng)機軸(zhou)承，如有曠(kuang)動(dong)、異聲等應更(geng)換(huan)(huan)軸(zhou)承。

如果播(bo)種(zhong)機完全(quan)不播(bo)種(zhong)，主要(yao)(yao)是(shi)磨(mo)(mo)損(sun)(sun)嚴重(zhong)或(huo)運輸、保管(guan)不當造成(cheng)傳動件變形，如方(fang)軸、軸套、傘(san)齒(chi)輪、排(pai)種(zhong)器等嚴重(zhong)磨(mo)(mo)損(sun)(sun)、變形，導致(zhi)風(feng)速和(he)風(feng)量不足而完全(quan)不播(bo)種(zhong)。此時，要(yao)(yao)全(quan)面檢修播(bo)種(zhong)機，如方(fang)軸要(yao)(yao)校直，配合(he)松曠的(de)可(ke)(ke)加(jia)墊(dian)片消除(chu)間隙(xi)，磨(mo)(mo)損(sun)(sun)嚴重(zhong)的(de)要(yao)(yao)焊補后磨(mo)(mo)平。傘(san)齒(chi)輪磨(mo)(mo)損(sun)(sun)過大(da)的(de)要(yao)(yao)成(cheng)對更換，磨(mo)(mo)損(sun)(sun)不太嚴重(zhong)的(de)可(ke)(ke)在內孔(kong)加(jia)墊(dian)片消除(chu)間隙(xi)。方(fang)向節可(ke)(ke)用推(tui)焊法填(tian)補磨(mo)(mo)痕(hen)，然后車平表面。裝復后應轉動靈(ling)活。排(pai)種(zhong)器要(yao)(yao)更換。維護(hu)時要(yao)(yao)注意方(fang)軸套和(he)軸、傘(san)齒(chi)輪的(de)潤滑，以(yi)減(jian)緩磨(mo)(mo)損(sun)(sun)。運輸中要(yao)(yao)防止碰撞。

為(wei)(wei)了提(ti)高(gao)(gao)排(pai)種(zhong)(zhong)(zhong)(zhong)器(qi)(qi)精確(que)(que)性(xing)，還需要(yao)做(zuo)到以下(xia)幾點：一(yi)(yi)是(shi)選(xuan)擇(ze)適(shi)(shi)當(dang)的排(pai)種(zhong)(zhong)(zhong)(zhong)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)孔(kong)。排(pai)種(zhong)(zhong)(zhong)(zhong)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)孔(kong)的大(da)(da)(da)小影響種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)能(neng)(neng)否準確(que)(que)而(er)(er)(er)穩定(ding)地被吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)在(zai)排(pai)種(zhong)(zhong)(zhong)(zhong)盤(pan)(pan)表面(mian)(mian)(mian)。試驗證明，較佳的吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)孔(kong)直徑為(wei)(wei)種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)直徑的0.5～0.7倍(bei)。二是(shi)選(xuan)擇(ze)適(shi)(shi)宜(yi)的作(zuo)(zuo)業(ye)(ye)(ye)速(su)度(du)(du)(du)(du)。作(zuo)(zuo)業(ye)(ye)(ye)速(su)度(du)(du)(du)(du)可改變種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)的線(xian)速(su)度(du)(du)(du)(du)，增大(da)(da)(da)種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)的慣(guan)性(xing)，從(cong)而(er)(er)(er)對種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)力(li)產(chan)生影響。作(zuo)(zuo)業(ye)(ye)(ye)速(su)度(du)(du)(du)(du)越大(da)(da)(da)，種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)的吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)力(li)越大(da)(da)(da)。三(san)是(shi)適(shi)(shi)宜(yi)的氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)(shi)真(zhen)(zhen)空(kong)度(du)(du)(du)(du)。氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)(shi)真(zhen)(zhen)空(kong)腔(qiang)是(shi)由氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)(shi)和(he)排(pai)種(zhong)(zhong)(zhong)(zhong)盤(pan)(pan)構成，真(zhen)(zhen)空(kong)度(du)(du)(du)(du)直接關系(xi)(xi)到種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)能(neng)(neng)否吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)在(zai)排(pai)種(zhong)(zhong)(zhong)(zhong)盤(pan)(pan)表面(mian)(mian)(mian)，它與重(zhong)力(li)、種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)的慣(guan)性(xing)力(li)、摩擦力(li)、離(li)心力(li)共(gong)同構成一(yi)(yi)個動態(tai)(tai)平衡，確(que)(que)保氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)排(pai)種(zhong)(zhong)(zhong)(zhong)器(qi)(qi)正(zheng)常工作(zuo)(zuo)。為(wei)(wei)了保持氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)工作(zuo)(zuo)腔(qiang)有(you)穩定(ding)的真(zhen)(zhen)空(kong)度(du)(du)(du)(du)，排(pai)種(zhong)(zhong)(zhong)(zhong)盤(pan)(pan)周邊(bian)的泄漏面(mian)(mian)(mian)積和(he)排(pai)種(zhong)(zhong)(zhong)(zhong)盤(pan)(pan)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)孔(kong)面(mian)(mian)(mian)積總(zong)和(he)與氣(qi)(qi)(qi)(qi)流管路截(jie)面(mian)(mian)(mian)之間有(you)一(yi)(yi)定(ding)的比例關系(xi)(xi)，當(dang)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)孔(kong)面(mian)(mian)(mian)積總(zong)和(he)超過(guo)(guo)一(yi)(yi)定(ding)數值(zhi)時，氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)(shi)將(jiang)不(bu)能(neng)(neng)形(xing)成足夠的真(zhen)(zhen)空(kong)度(du)(du)(du)(du)，導致機具無(wu)法正(zheng)常工作(zuo)(zuo)。當(dang)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)孔(kong)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)到種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)后真(zhen)(zhen)空(kong)度(du)(du)(du)(du)會(hui)(hui)(hui)上(shang)升，而(er)(er)(er)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)孔(kong)上(shang)沒有(you)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)滿(man)種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)，會(hui)(hui)(hui)使(shi)氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)(shi)的真(zhen)(zhen)空(kong)度(du)(du)(du)(du)大(da)(da)(da)大(da)(da)(da)下(xia)降，使(shi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)種(zhong)(zhong)(zhong)(zhong)更困難。通過(guo)(guo)密(mi)封氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)管接頭(tou)、精密(mi)加工排(pai)種(zhong)(zhong)(zhong)(zhong)盤(pan)(pan)和(he)氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)(shi)結合面(mian)(mian)(mian)、選(xuan)擇(ze)適(shi)(shi)當(dang)的吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)孔(kong)等措施，可以大(da)(da)(da)大(da)(da)(da)提(ti)高(gao)(gao)種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)的吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)能(neng)(neng)力(li)。四是(shi)使(shi)用刮(gua)種(zhong)(zhong)(zhong)(zhong)裝置。刮(gua)種(zhong)(zhong)(zhong)(zhong)片的作(zuo)(zuo)用是(shi)將(jiang)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)上(shang)來的多(duo)余種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)碰撞掉，從(cong)而(er)(er)(er)使(shi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)(fu)(fu)(fu)上(shang)的種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)加穩定(ding)，進(jin)而(er)(er)(er)提(ti)高(gao)(gao)氣(qi)(qi)(qi)(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)(xi)排(pai)種(zhong)(zhong)(zhong)
