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(chuang)的形狀可分(fen)為撒播(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)力可分(fen)為人力播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)、畜力播(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)器取排種(zhong)(zhong)(zhong)原(yuan)理(li)可分(fen)為氣(qi)動(dong)式(shi)(shi)(shi)和機(ji)(ji)械式(shi)(shi)(shi)；按(an)聯合作業(ye)形式(shi)(shi)(shi)可分(fen)為旋耕播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)、覆膜播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)、免(mian)耕播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)。

播種機械工作原理

播種機通過傳動(dong)系統(tong)帶動(dong)排(pai)(pai)種器、排(pai)(pai)肥(fei)(fei)(fei)器，按(an)要求種肥(fei)(fei)(fei)量將(jiang)從種肥(fei)(fei)(fei)箱進入(ru)排(pai)(pai)種器和(he)(he)排(pai)(pai)肥(fei)(fei)(fei)器的(de)種子和(he)(he)肥(fei)(fei)(fei)料排(pai)(pai)到由開溝(gou)器開好的(de)種溝(gou)和(he)(he)肥(fei)(fei)(fei)溝(gou)里，隨后覆(fu)土器覆(fu)土，鎮壓器壓實種床，完成播種作業。

播種機械的構造和工作過程

播種(zhong)(zhong)機(ji)一般(ban)由(you)種(zhong)(zhong)子(zi)箱(xiang)、排種(zhong)(zhong)器、輸(shu)種(zhong)(zhong)管、開(kai)溝器、覆土器、行走(zou)輪、轉動機(ji)構(gou)等組成(cheng)。工作時，開(kai)溝器在地上開(kai)出種(zhong)(zhong)溝，種(zhong)(zhong)子(zi)箱(xiang)內的(de)種(zhong)(zhong)子(zi)由(you)排種(zhong)(zhong)器排出，經輸(shu)種(zhong)(zhong)管落入種(zhong)(zhong)溝，再由(you)覆土器覆土完成(cheng)播種(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(ying)外(wai)觀整潔完好，有可(ke)靠的防護裝置，記(ji)得索要發票。

播種機怎么用

播(bo)(bo)種(zhong)機在播(bo)(bo)種(zhong)時，應按照種(zhong)子(zi)(zi)的(de)特點，對其進行播(bo)(bo)種(zhong)。如播(bo)(bo)種(zhong)的(de)行距應該控制在20厘米(mi)左(zuo)右，不能過(guo)(guo)寬也不能過(guo)(guo)窄。播(bo)(bo)種(zhong)深(shen)(shen)度應控制在1.5—3.0厘米(mi)，但是也要考慮到特殊情(qing)況(kuang)，不同的(de)土(tu)壤(rang)(rang)播(bo)(bo)種(zhong)的(de)深(shen)(shen)度也不同，土(tu)壤(rang)(rang)偏旱，播(bo)(bo)深(shen)(shen)就要略深(shen)(shen)一點，這樣(yang)可(ke)以(yi)防止種(zhong)子(zi)(zi)播(bo)(bo)淺，土(tu)壤(rang)(rang)過(guo)(guo)干而(er)不能生長。因此，農機手在播(bo)(bo)種(zhong)時，一定要充分考慮種(zhong)子(zi)(zi)、土(tu)壤(rang)(rang)等情(qing)況(kuang)，確保(bao)種(zhong)子(zi)(zi)的(de)健(jian)康(kang)成(cheng)長。
