播種機有哪些種類

播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)按(an)種(zhong)(zhong)(zhong)子播(bo)(bo)(bo)到種(zhong)(zhong)(zhong)床的形(xing)狀可分(fen)為(wei)撒播(bo)(bo)(bo)機(ji)(ji)、條播(bo)(bo)(bo)機(ji)(ji)、穴播(bo)(bo)(bo)機(ji)(ji)；按(an)動(dong)力(li)可分(fen)為(wei)人力(li)播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)、畜(chu)力(li)播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)和機(ji)(ji)械播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)；按(an)排種(zhong)(zhong)(zhong)器取(qu)排種(zhong)(zhong)(zhong)原理可分(fen)為(wei)氣動(dong)式(shi)(shi)和機(ji)(ji)械式(shi)(shi)；按(an)聯合作業(ye)形(xing)式(shi)(shi)可分(fen)為(wei)旋(xuan)耕(geng)播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)、覆(fu)膜播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)、免耕(geng)播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)。

播種機械工作原理

播種(zhong)(zhong)機通過傳(chuan)動系統帶動排(pai)種(zhong)(zhong)器(qi)、排(pai)肥器(qi)，按要求種(zhong)(zhong)肥量將從種(zhong)(zhong)肥箱進入排(pai)種(zhong)(zhong)器(qi)和(he)排(pai)肥器(qi)的(de)種(zhong)(zhong)子和(he)肥料排(pai)到由開(kai)溝器(qi)開(kai)好(hao)的(de)種(zhong)(zhong)溝和(he)肥溝里(li)，隨后覆(fu)土(tu)器(qi)覆(fu)土(tu)，鎮壓器(qi)壓實種(zhong)(zhong)床，完(wan)成播種(zhong)(zhong)作(zuo)業。

播種機械的構造和工作過程

播種(zhong)機一般由(you)(you)種(zhong)子(zi)箱、排種(zhong)器(qi)(qi)、輸種(zhong)管(guan)、開溝器(qi)(qi)、覆(fu)土器(qi)(qi)、行走輪、轉動機構等組成。工作時，開溝器(qi)(qi)在地上(shang)開出(chu)種(zhong)溝，種(zhong)子(zi)箱內的(de)種(zhong)子(zi)由(you)(you)排種(zhong)器(qi)(qi)排出(chu)，經(jing)輸種(zhong)管(guan)落入(ru)種(zhong)溝，再(zai)由(you)(you)覆(fu)土器(qi)(qi)覆(fu)土完成播種(zhong)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外觀整潔完好，有可(ke)靠的防(fang)護(hu)裝置，記得索要(yao)發票。

播種機怎么用

播(bo)種(zhong)(zhong)(zhong)機(ji)在(zai)播(bo)種(zhong)(zhong)(zhong)時，應按照種(zhong)(zhong)(zhong)子(zi)的(de)特(te)點，對其進行播(bo)種(zhong)(zhong)(zhong)。如播(bo)種(zhong)(zhong)(zhong)的(de)行距應該控制在(zai)20厘米(mi)左右，不(bu)能(neng)過寬也(ye)不(bu)能(neng)過窄(zhai)。播(bo)種(zhong)(zhong)(zhong)深度應控制在(zai)1.5—3.0厘米(mi)，但是(shi)也(ye)要考慮到特(te)殊情(qing)況，不(bu)同(tong)的(de)土壤(rang)播(bo)種(zhong)(zhong)(zhong)的(de)深度也(ye)不(bu)同(tong)，土壤(rang)偏旱(han)，播(bo)深就(jiu)要略(lve)深一(yi)點，這(zhe)樣可以(yi)防止種(zhong)(zhong)(zhong)子(zi)播(bo)淺(qian)，土壤(rang)過干而(er)不(bu)能(neng)生(sheng)長(chang)。因此，農機(ji)手在(zai)播(bo)種(zhong)(zhong)(zhong)時，一(yi)定要充(chong)分考慮種(zhong)(zhong)(zhong)子(zi)、土壤(rang)等情(qing)況，確保種(zhong)(zhong)(zhong)子(zi)的(de)健康成長(chang)。
