播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)按種(zhong)(zhong)(zhong)子播(bo)(bo)(bo)(bo)到種(zhong)(zhong)(zhong)床(chuang)的形狀(zhuang)可(ke)分為(wei)撒播(bo)(bo)(bo)(bo)機(ji)、條播(bo)(bo)(bo)(bo)機(ji)、穴播(bo)(bo)(bo)(bo)機(ji)；按動(dong)力(li)可(ke)分為(wei)人(ren)力(li)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)、畜力(li)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)和機(ji)械(xie)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)；按排種(zhong)(zhong)(zhong)器(qi)取排種(zhong)(zhong)(zhong)原理可(ke)分為(wei)氣動(dong)式和機(ji)械(xie)式；按聯合作業形式可(ke)分為(wei)旋耕播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)、覆膜(mo)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)、免耕播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)。

播種機械工作原理

播(bo)種(zhong)(zhong)機通過傳(chuan)動(dong)系(xi)統帶動(dong)排(pai)(pai)種(zhong)(zhong)器、排(pai)(pai)肥器，按要求種(zhong)(zhong)肥量將從種(zhong)(zhong)肥箱進入排(pai)(pai)種(zhong)(zhong)器和排(pai)(pai)肥器的(de)(de)種(zhong)(zhong)子和肥料(liao)排(pai)(pai)到由開溝器開好的(de)(de)種(zhong)(zhong)溝和肥溝里，隨后覆土(tu)器覆土(tu)，鎮壓(ya)器壓(ya)實種(zhong)(zhong)床，完(wan)成播(bo)種(zhong)(zhong)作業。

播種機械的構造和工作過程

播(bo)種機一(yi)般由種子(zi)(zi)箱、排(pai)種器(qi)(qi)、輸種管、開(kai)溝器(qi)(qi)、覆(fu)土(tu)器(qi)(qi)、行走輪(lun)、轉動機構等(deng)組成(cheng)。工(gong)作時，開(kai)溝器(qi)(qi)在地上開(kai)出種溝，種子(zi)(zi)箱內(nei)的(de)種子(zi)(zi)由排(pai)種器(qi)(qi)排(pai)出，經輸種管落入(ru)種溝，再由覆(fu)土(tu)器(qi)(qi)覆(fu)土(tu)完成(cheng)播(bo)種作業。

如何選購播種機

選購播種機應根據作業的面積、田地的地勢、播種的深度、土壤的質地和干濕度等因素選擇合適的型號。選好型號后要確定播種機的質量，選購的播種機品牌應(ying)外觀整潔完(wan)好，有可靠的防護裝置(zhi)，記得索要發票。

播種機怎么用

播(bo)(bo)種(zhong)機(ji)在播(bo)(bo)種(zhong)時，應(ying)按(an)照(zhao)種(zhong)子(zi)(zi)的(de)(de)(de)(de)特(te)點，對其(qi)進(jin)行(xing)播(bo)(bo)種(zhong)。如播(bo)(bo)種(zhong)的(de)(de)(de)(de)行(xing)距應(ying)該控制在20厘米(mi)左右，不(bu)(bu)能(neng)過(guo)(guo)寬也不(bu)(bu)能(neng)過(guo)(guo)窄。播(bo)(bo)種(zhong)深度應(ying)控制在1.5—3.0厘米(mi)，但(dan)是也要考(kao)慮(lv)(lv)到特(te)殊情(qing)況，不(bu)(bu)同(tong)的(de)(de)(de)(de)土(tu)壤(rang)播(bo)(bo)種(zhong)的(de)(de)(de)(de)深度也不(bu)(bu)同(tong)，土(tu)壤(rang)偏(pian)旱，播(bo)(bo)深就要略深一點，這樣(yang)可(ke)以防止(zhi)種(zhong)子(zi)(zi)播(bo)(bo)淺，土(tu)壤(rang)過(guo)(guo)干而不(bu)(bu)能(neng)生長。因此(ci)，農機(ji)手(shou)在播(bo)(bo)種(zhong)時，一定要充分考(kao)慮(lv)(lv)種(zhong)子(zi)(zi)、土(tu)壤(rang)等情(qing)況，確(que)保種(zhong)子(zi)(zi)的(de)(de)(de)(de)健康成長。
