播種機有哪些種類

播(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)按種(zhong)子(zi)播(bo)(bo)(bo)到(dao)種(zhong)床的形狀可分(fen)(fen)(fen)為撒(sa)播(bo)(bo)(bo)機(ji)(ji)(ji)、條播(bo)(bo)(bo)機(ji)(ji)(ji)、穴播(bo)(bo)(bo)機(ji)(ji)(ji)；按動力可分(fen)(fen)(fen)為人力播(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)、畜(chu)力播(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)和機(ji)(ji)(ji)械(xie)播(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)；按排種(zhong)器取排種(zhong)原理(li)可分(fen)(fen)(fen)為氣(qi)動式(shi)(shi)和機(ji)(ji)(ji)械(xie)式(shi)(shi)；按聯合(he)作業形式(shi)(shi)可分(fen)(fen)(fen)為旋耕播(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)、覆膜播(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)、免耕播(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)。

播種機械工作原理

播(bo)(bo)種(zhong)機通過傳動系(xi)統帶(dai)動排種(zhong)器、排肥(fei)器，按要求種(zhong)肥(fei)量將從(cong)種(zhong)肥(fei)箱進入排種(zhong)器和排肥(fei)器的(de)種(zhong)子和肥(fei)料排到由開(kai)溝器開(kai)好的(de)種(zhong)溝和肥(fei)溝里(li)，隨后(hou)覆(fu)土器覆(fu)土，鎮壓器壓實種(zhong)床，完成播(bo)(bo)種(zhong)作業。

播種機械的構造和工作過程

播種(zhong)(zhong)(zhong)(zhong)機一(yi)般由(you)種(zhong)(zhong)(zhong)(zhong)子(zi)箱、排種(zhong)(zhong)(zhong)(zhong)器(qi)、輸種(zhong)(zhong)(zhong)(zhong)管(guan)(guan)、開溝器(qi)、覆土器(qi)、行(xing)走輪、轉(zhuan)動機構等組成。工(gong)作時，開溝器(qi)在地上開出(chu)種(zhong)(zhong)(zhong)(zhong)溝，種(zhong)(zhong)(zhong)(zhong)子(zi)箱內(nei)的種(zhong)(zhong)(zhong)(zhong)子(zi)由(you)排種(zhong)(zhong)(zhong)(zhong)器(qi)排出(chu)，經(jing)輸種(zhong)(zhong)(zhong)(zhong)管(guan)(guan)落入種(zhong)(zhong)(zhong)(zhong)溝，再由(you)覆土器(qi)覆土完成播種(zhong)(zhong)(zhong)(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(guan)整潔(jie)完(wan)好，有可靠的防護裝置，記得索要發票。

播種機怎么用

播(bo)(bo)種(zhong)(zhong)機在播(bo)(bo)種(zhong)(zhong)時，應(ying)(ying)按照種(zhong)(zhong)子的(de)特點(dian)，對其進行播(bo)(bo)種(zhong)(zhong)。如播(bo)(bo)種(zhong)(zhong)的(de)行距應(ying)(ying)該控制在20厘米(mi)左右，不能(neng)過寬也不能(neng)過窄。播(bo)(bo)種(zhong)(zhong)深(shen)(shen)度應(ying)(ying)控制在1.5—3.0厘米(mi)，但是也要(yao)考慮(lv)(lv)到特殊情(qing)況，不同的(de)土壤(rang)(rang)播(bo)(bo)種(zhong)(zhong)的(de)深(shen)(shen)度也不同，土壤(rang)(rang)偏旱，播(bo)(bo)深(shen)(shen)就(jiu)要(yao)略深(shen)(shen)一(yi)點(dian)，這樣可(ke)以防止種(zhong)(zhong)子播(bo)(bo)淺，土壤(rang)(rang)過干而(er)不能(neng)生長。因此，農機手在播(bo)(bo)種(zhong)(zhong)時，一(yi)定(ding)要(yao)充分考慮(lv)(lv)種(zhong)(zhong)子、土壤(rang)(rang)等(deng)情(qing)況，確保(bao)種(zhong)(zhong)子的(de)健康(kang)成(cheng)長。
