氣(qi)吸(xi)(xi)(xi)式精(jing)(jing)量播(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)(ji)(ji)是一種(zhong)(zhong)(zhong)(zhong)(zhong)高效(xiao)節能的(de)多(duo)用(yong)途精(jing)(jing)量播(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)(ji)(ji)，與(yu)目前使用(yong)的(de)條播(bo)(bo)(bo)機(ji)(ji)(ji)相比一般節種(zhong)(zhong)(zhong)(zhong)(zhong)50%。氣(qi)吸(xi)(xi)(xi)式精(jing)(jing)量播(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)(ji)(ji)主要由機(ji)(ji)(ji)架總成(cheng)(cheng)(cheng)(cheng)、地輪總成(cheng)(cheng)(cheng)(cheng)、四桿機(ji)(ji)(ji)構、排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)(qi)總成(cheng)(cheng)(cheng)(cheng)、排肥(fei)器(qi)(qi)總成(cheng)(cheng)(cheng)(cheng)、種(zhong)(zhong)(zhong)(zhong)(zhong)子開溝(gou)(gou)器(qi)(qi)總成(cheng)(cheng)(cheng)(cheng)、化(hua)肥(fei)開溝(gou)(gou)器(qi)(qi)總成(cheng)(cheng)(cheng)(cheng)、覆(fu)土(tu)器(qi)(qi)總成(cheng)(cheng)(cheng)(cheng)、鎮壓(ya)輪總成(cheng)(cheng)(cheng)(cheng)、中間傳動器(qi)(qi)總成(cheng)(cheng)(cheng)(cheng)及風機(ji)(ji)(ji)總成(cheng)(cheng)(cheng)(cheng)和風機(ji)(ji)(ji)傳動器(qi)(qi)總成(cheng)(cheng)(cheng)(cheng)等部件組成(cheng)(cheng)(cheng)(cheng)，能一次完成(cheng)(cheng)(cheng)(cheng)開溝(gou)(gou)、施(shi)肥(fei)、播(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)、覆(fu)土(tu)、鎮壓(ya)等多(duo)道工(gong)序，其行距(ju)(ju)、株距(ju)(ju)、播(bo)(bo)(bo)深、排肥(fei)量、覆(fu)土(tu)量、鎮壓(ya)力等可在較大范圍內調整，而且具有較大的(de)適應性，在氣(qi)吸(xi)(xi)(xi)排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)(qi)上更換不同排種(zhong)(zhong)(zhong)(zhong)(zhong)盤(pan)，可精(jing)(jing)播(bo)(bo)(bo)玉(yu)米、甜菜(cai)、蓖麻、黃豆、高梁等多(duo)種(zhong)(zhong)(zhong)(zhong)(zhong)農作物(wu)。氣(qi)吸(xi)(xi)(xi)播(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)的(de)關鍵技術(shu)就是能夠將種(zhong)(zhong)(zhong)(zhong)(zhong)子可靠地單(dan)粒分離并準確(que)地投種(zhong)(zhong)(zhong)(zhong)(zhong)，現以(yi)垂直圓盤(pan)氣(qi)吸(xi)(xi)(xi)排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)(qi)為例(li)，探(tan)討提高排種(zhong)(zhong)(zhong)(zhong)(zhong)精(jing)(jing)確(que)性的(de)方法(fa)。

1．垂直圓盤氣吸排種器的工作原理

垂直圓盤氣吸(xi)式排(pai)(pai)種(zhong)(zhong)器的(de)(de)氣吸(xi)室與風(feng)(feng)機進(jin)風(feng)(feng)口相連，排(pai)(pai)種(zhong)(zhong)盤的(de)(de)一(yi)側為氣吸(xi)室的(de)(de)負壓(ya)道(dao)，另一(yi)側為充種(zhong)(zhong)區。當高速(su)旋轉(zhuan)的(de)(de)風(feng)(feng)機產生負壓(ya)時(shi)(shi)，地輪帶動(dong)排(pai)(pai)種(zhong)(zhong)盤轉(zhuan)動(dong)。當排(pai)(pai)種(zhong)(zhong)盤上(shang)(shang)的(de)(de)排(pai)(pai)種(zhong)(zhong)孔轉(zhuan)到(dao)種(zhong)(zhong)子(zi)室充種(zhong)(zhong)區時(shi)(shi)，種(zhong)(zhong)子(zi)室與大氣相通，此時(shi)(shi)種(zhong)(zhong)子(zi)被吸(xi)附在(zai)排(pai)(pai)種(zhong)(zhong)孔上(shang)(shang)。當排(pai)(pai)種(zhong)(zhong)盤轉(zhuan)到(dao)投(tou)種(zhong)(zhong)區時(shi)(shi)，負壓(ya)消失，種(zhong)(zhong)子(zi)在(zai)重力作用(yong)下落入(ru)開溝器開好(hao)的(de)(de)溝內(nei)。排(pai)(pai)種(zhong)(zhong)器上(shang)(shang)設有鋸(ju)齒式刮(gua)種(zhong)(zhong)器，可(ke)以刮(gua)去多余(yu)的(de)(de)種(zhong)(zhong)子(zi)，滿足(zu)精量(liang)播種(zhong)(zhong)的(de)(de)要求。

2．排種量不穩定的影響因素

造(zao)成(cheng)排(pai)(pai)種(zhong)(zhong)量(liang)(liang)不(bu)(bu)穩定的原(yuan)因主(zhu)要(yao)(yao)有以下(xia)幾點：一(yi)是(shi)(shi)(shi)吸(xi)(xi)(xi)(xi)氣(qi)(qi)(qi)(qi)管(guan)路出(chu)現(xian)(xian)(xian)問(wen)題(ti)。吸(xi)(xi)(xi)(xi)氣(qi)(qi)(qi)(qi)管(guan)路有漏(lou)(lou)氣(qi)(qi)(qi)(qi)的地(di)方，如漏(lou)(lou)洞(dong)、接頭松動、裂(lie)紋等(deng)，導(dao)致(zhi)(zhi)氣(qi)(qi)(qi)(qi)壓下(xia)降(jiang)，吸(xi)(xi)(xi)(xi)力減(jian)(jian)小(xiao)，一(yi)部分或(huo)(huo)全(quan)部漏(lou)(lou)播(bo)，主(zhu)要(yao)(yao)表現(xian)(xian)(xian)為個別壟行播(bo)量(liang)(liang)減(jian)(jian)少或(huo)(huo)漏(lou)(lou)播(bo)。二是(shi)(shi)(shi)膠(jiao)管(guan)質量(liang)(liang)出(chu)現(xian)(xian)(xian)問(wen)題(ti)。吸(xi)(xi)(xi)(xi)氣(qi)(qi)(qi)(qi)膠(jiao)管(guan)質量(liang)(liang)差、老化、破損(sun)(sun)、漏(lou)(lou)洞(dong)或(huo)(huo)產生脫離層而使(shi)(shi)氣(qi)(qi)(qi)(qi)流阻(zu)(zu)力加大，氣(qi)(qi)(qi)(qi)壓降(jiang)低，難以吸(xi)(xi)(xi)(xi)附(fu)種(zhong)(zhong)子，出(chu)現(xian)(xian)(xian)排(pai)(pai)種(zhong)(zhong)量(liang)(liang)減(jian)(jian)少或(huo)(huo)漏(lou)(lou)播(bo)現(xian)(xian)(xian)象(xiang)(xiang)。三是(shi)(shi)(shi)風(feng)(feng)(feng)機(ji)兩側軸承出(chu)現(xian)(xian)(xian)問(wen)題(ti)。磨(mo)損(sun)(sun)嚴(yan)重、年(nian)久失修或(huo)(huo)長(chang)期缺油，導(dao)致(zhi)(zhi)阻(zu)(zu)力增大、轉(zhuan)(zhuan)速(su)(su)(su)(su)下(xia)降(jiang)、氣(qi)(qi)(qi)(qi)壓不(bu)(bu)足(zu)(zu)，表現(xian)(xian)(xian)為整機(ji)播(bo)量(liang)(liang)不(bu)(bu)足(zu)(zu)或(huo)(huo)完全(quan)漏(lou)(lou)播(bo)。四是(shi)(shi)(shi)風(feng)(feng)(feng)機(ji)轉(zhuan)(zhuan)速(su)(su)(su)(su)出(chu)現(xian)(xian)(xian)問(wen)題(ti)。風(feng)(feng)(feng)機(ji)轉(zhuan)(zhuan)速(su)(su)(su)(su)不(bu)(bu)足(zu)(zu)，吸(xi)(xi)(xi)(xi)力不(bu)(bu)夠。主(zhu)機(ji)轉(zhuan)(zhuan)速(su)(su)(su)(su)降(jiang)低、動力輸出(chu)軸出(chu)現(xian)(xian)(xian)故(gu)障或(huo)(huo)三角(jiao)傳動帶陳(chen)舊、磨(mo)損(sun)(sun)嚴(yan)重、拉長(chang)、松弦(xian)等(deng)，都會導(dao)致(zhi)(zhi)風(feng)(feng)(feng)機(ji)轉(zhuan)(zhuan)速(su)(su)(su)(su)下(xia)降(jiang)。五是(shi)(shi)(shi)排(pai)(pai)種(zhong)(zhong)盤(pan)出(chu)現(xian)(xian)(xian)問(wen)題(ti)。排(pai)(pai)種(zhong)(zhong)盤(pan)因保管(guan)、安裝不(bu)(bu)當(dang)而產生變(bian)形、銹蝕(shi)或(huo)(huo)種(zhong)(zhong)室變(bian)形等(deng)使(shi)(shi)排(pai)(pai)種(zhong)(zhong)盤(pan)與(yu)種(zhong)(zhong)室密封不(bu)(bu)好，產生漏(lou)(lou)氣(qi)(qi)(qi)(qi)，導(dao)致(zhi)(zhi)種(zhong)(zhong)子吸(xi)(xi)(xi)(xi)力不(bu)(bu)足(zu)(zu)；種(zhong)(zhong)子里混有雜物，將(jiang)排(pai)(pai)種(zhong)(zhong)盤(pan)孔(kong)眼(yan)堵(du)死，造(zao)成(cheng)漏(lou)(lou)播(bo)種(zhong)(zhong)；排(pai)(pai)種(zhong)(zhong)盤(pan)型號不(bu)(bu)當(dang)，孔(kong)眼(yan)過小(xiao)，吸(xi)(xi)(xi)(xi)力不(bu)(bu)足(zu)(zu)，導(dao)致(zhi)(zhi)無法(fa)吸(xi)(xi)(xi)(xi)附(fu)種(zhong)(zhong)子或(huo)(huo)吸(xi)(xi)(xi)(xi)量(liang)(liang)少，進而產生漏(lou)(lou)播(bo)或(huo)(huo)播(bo)量(liang)(liang)不(bu)(bu)足(zu)(zu)現(xian)(xian)(xian)象(xiang)(xiang)。

3．提高排種器精確性的措施

發(fa)現(xian)漏播(bo)現(xian)象，應(ying)立即(ji)停(ting)車熄火，將播(bo)種機落(luo)地檢查原因。若接頭連(lian)接不(bu)牢，可重新接牢；有較小孔(kong)眼或裂(lie)紋(wen)的(de)可用膠帶貼補，孔(kong)眼過(guo)大(da)或裂(lie)紋(wen)過(guo)長應(ying)更(geng)換新管；輸氣管內壁脫層阻力大(da)應(ying)更(geng)換新管。排種盤或排種室變形可試校，校平后仍然漏氣應(ying)更(geng)換新品；發(fa)動機轉速正常而風(feng)機風(feng)量不(bu)足，要檢查風(feng)機軸承(cheng)，如有曠動、異聲(sheng)等(deng)應(ying)更(geng)換軸承(cheng)。

如(ru)果(guo)播種機(ji)完(wan)全(quan)不播種，主要(yao)是磨(mo)(mo)(mo)損(sun)嚴(yan)(yan)重(zhong)(zhong)或運(yun)輸、保(bao)管不當(dang)造成(cheng)傳動件變(bian)形(xing)，如(ru)方軸(zhou)、軸(zhou)套(tao)、傘齒(chi)輪、排種器等嚴(yan)(yan)重(zhong)(zhong)磨(mo)(mo)(mo)損(sun)、變(bian)形(xing)，導致風速(su)和風量不足而完(wan)全(quan)不播種。此時(shi)，要(yao)全(quan)面檢修(xiu)播種機(ji)，如(ru)方軸(zhou)要(yao)校直，配合松曠的(de)可(ke)加(jia)墊(dian)片(pian)消除間(jian)隙，磨(mo)(mo)(mo)損(sun)嚴(yan)(yan)重(zhong)(zhong)的(de)要(yao)焊補后磨(mo)(mo)(mo)平(ping)。傘齒(chi)輪磨(mo)(mo)(mo)損(sun)過大的(de)要(yao)成(cheng)對更換，磨(mo)(mo)(mo)損(sun)不太嚴(yan)(yan)重(zhong)(zhong)的(de)可(ke)在內孔加(jia)墊(dian)片(pian)消除間(jian)隙。方向節(jie)可(ke)用推焊法填補磨(mo)(mo)(mo)痕，然后車平(ping)表面。裝復后應轉動靈活。排種器要(yao)更換。維(wei)護時(shi)要(yao)注(zhu)意方軸(zhou)套(tao)和軸(zhou)、傘齒(chi)輪的(de)潤滑(hua)，以減緩磨(mo)(mo)(mo)損(sun)。運(yun)輸中(zhong)要(yao)防止碰撞(zhuang)。

為(wei)了提高排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)(qi)精(jing)確性(xing)，還需要做到以下幾點(dian)：一是(shi)(shi)選(xuan)(xuan)擇(ze)適(shi)(shi)當(dang)的(de)(de)(de)(de)(de)(de)排種(zhong)(zhong)(zhong)(zhong)(zhong)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)孔(kong)。排種(zhong)(zhong)(zhong)(zhong)(zhong)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)孔(kong)的(de)(de)(de)(de)(de)(de)大(da)(da)小影(ying)響種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)能否(fou)準確而穩定地被吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)在(zai)排種(zhong)(zhong)(zhong)(zhong)(zhong)盤表(biao)面(mian)。試驗證明，較佳的(de)(de)(de)(de)(de)(de)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)孔(kong)直(zhi)徑(jing)為(wei)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)直(zhi)徑(jing)的(de)(de)(de)(de)(de)(de)0.5～0.7倍(bei)。二是(shi)(shi)選(xuan)(xuan)擇(ze)適(shi)(shi)宜(yi)的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)(zuo)業(ye)(ye)速度(du)(du)。作(zuo)(zuo)(zuo)業(ye)(ye)速度(du)(du)可改變種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)(de)(de)(de)線速度(du)(du)，增(zeng)大(da)(da)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)(de)(de)(de)慣性(xing)，從而對種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)力(li)(li)產生影(ying)響。作(zuo)(zuo)(zuo)業(ye)(ye)速度(du)(du)越大(da)(da)，種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)(de)(de)(de)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)力(li)(li)越大(da)(da)。三是(shi)(shi)適(shi)(shi)宜(yi)的(de)(de)(de)(de)(de)(de)氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)真空(kong)度(du)(du)。氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)真空(kong)腔(qiang)(qiang)(qiang)是(shi)(shi)由氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)和排種(zhong)(zhong)(zhong)(zhong)(zhong)盤構成，真空(kong)度(du)(du)直(zhi)接(jie)關系到種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)能否(fou)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)在(zai)排種(zhong)(zhong)(zhong)(zhong)(zhong)盤表(biao)面(mian)，它與重力(li)(li)、種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)(de)(de)(de)慣性(xing)力(li)(li)、摩擦(ca)力(li)(li)、離(li)(li)心(xin)力(li)(li)共同構成一個(ge)動態平(ping)衡，確保氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)(qi)正常工作(zuo)(zuo)(zuo)。為(wei)了保持氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)工作(zuo)(zuo)(zuo)腔(qiang)(qiang)(qiang)有穩定的(de)(de)(de)(de)(de)(de)真空(kong)度(du)(du)，排種(zhong)(zhong)(zhong)(zhong)(zhong)盤周邊的(de)(de)(de)(de)(de)(de)泄漏面(mian)積和排種(zhong)(zhong)(zhong)(zhong)(zhong)盤吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)孔(kong)面(mian)積總和與氣(qi)流管路(lu)截面(mian)之間(jian)(jian)有一定的(de)(de)(de)(de)(de)(de)比例關系，當(dang)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)孔(kong)面(mian)積總和超過一定數值時，氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)將(jiang)(jiang)不能形成足夠(gou)的(de)(de)(de)(de)(de)(de)真空(kong)度(du)(du)，導致機(ji)具無法正常工作(zuo)(zuo)(zuo)。當(dang)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)孔(kong)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)到種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)后(hou)真空(kong)度(du)(du)會(hui)上(shang)(shang)升，而吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)孔(kong)上(shang)(shang)沒有吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)滿(man)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)，會(hui)使(shi)(shi)氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)的(de)(de)(de)(de)(de)(de)真空(kong)度(du)(du)大(da)(da)大(da)(da)下降，使(shi)(shi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)種(zhong)(zhong)(zhong)(zhong)(zhong)更困難。通(tong)過密封氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)管接(jie)頭、精(jing)密加工排種(zhong)(zhong)(zhong)(zhong)(zhong)盤和氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)室(shi)結合面(mian)、選(xuan)(xuan)擇(ze)適(shi)(shi)當(dang)的(de)(de)(de)(de)(de)(de)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)孔(kong)等措施，可以大(da)(da)大(da)(da)提高種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)的(de)(de)(de)(de)(de)(de)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)能力(li)(li)。四是(shi)(shi)使(shi)(shi)用刮種(zhong)(zhong)(zhong)(zhong)(zhong)裝置(zhi)。刮種(zhong)(zhong)(zhong)(zhong)(zhong)片的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)(zuo)用是(shi)(shi)將(jiang)(jiang)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)上(shang)(shang)來的(de)(de)(de)(de)(de)(de)多余種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)碰撞掉，從而使(shi)(shi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)上(shang)(shang)的(de)(de)(de)(de)(de)(de)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)加穩定，進(jin)而提高氣(qi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)(qi)的(de)(de)(de)(de)(de)(de)單粒分離(li)(li)率。五是(shi)(shi)排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)(qi)腔(qiang)(qiang)(qiang)體設(she)計要合理。當(dang)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)處于松散(san)的(de)(de)(de)(de)(de)(de)狀態時，種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)間(jian)(jian)的(de)(de)(de)(de)(de)(de)摩擦(ca)力(li)(li)會(hui)減少(shao)，架空(kong)現象很(hen)少(shao)發生，有利(li)于種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)。為(wei)了使(shi)(shi)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)(zi)處于松散(san)狀態并(bing)能夠(gou)不斷補充，排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)(qi)腔(qiang)(qiang)(qiang)體的(de)(de)(de)(de)(de)(de)設(she)計很(hen)重要。首先，將(jiang)(jiang)吸(xi)(xi)(xi)(xi)(xi)(xi)(xi)附(fu)(fu)(fu)腔(qian
