播種機有哪些種類

播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)按種(zhong)子播(bo)(bo)(bo)(bo)到種(zhong)床的形狀可(ke)分(fen)為(wei)撒播(bo)(bo)(bo)(bo)機(ji)(ji)、條播(bo)(bo)(bo)(bo)機(ji)(ji)、穴播(bo)(bo)(bo)(bo)機(ji)(ji)；按動力可(ke)分(fen)為(wei)人力播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)、畜力播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)和(he)機(ji)(ji)械播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)；按排(pai)種(zhong)器取排(pai)種(zhong)原理可(ke)分(fen)為(wei)氣動式和(he)機(ji)(ji)械式；按聯合作業形式可(ke)分(fen)為(wei)旋耕(geng)播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)、覆(fu)膜播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)、免耕(geng)播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)。

播種機械工作原理

播種(zhong)(zhong)機通(tong)過傳動(dong)系統(tong)帶動(dong)排種(zhong)(zhong)器(qi)(qi)(qi)、排肥(fei)器(qi)(qi)(qi)，按(an)要求(qiu)種(zhong)(zhong)肥(fei)量將從種(zhong)(zhong)肥(fei)箱進入排種(zhong)(zhong)器(qi)(qi)(qi)和(he)排肥(fei)器(qi)(qi)(qi)的種(zhong)(zhong)子和(he)肥(fei)料排到由開溝器(qi)(qi)(qi)開好的種(zhong)(zhong)溝和(he)肥(fei)溝里，隨后覆(fu)土(tu)器(qi)(qi)(qi)覆(fu)土(tu)，鎮壓器(qi)(qi)(qi)壓實種(zhong)(zhong)床，完(wan)成播種(zhong)(zhong)作業。

播種機械的構造和工作過程

播種(zhong)(zhong)機一(yi)般由(you)種(zhong)(zhong)子(zi)(zi)箱(xiang)、排種(zhong)(zhong)器、輸種(zhong)(zhong)管(guan)、開(kai)(kai)溝器、覆土器、行走(zou)輪、轉動機構等組(zu)成(cheng)。工作時(shi)，開(kai)(kai)溝器在地上開(kai)(kai)出種(zhong)(zhong)溝，種(zhong)(zhong)子(zi)(zi)箱(xiang)內的(de)種(zhong)(zhong)子(zi)(zi)由(you)排種(zhong)(zhong)器排出，經輸種(zhong)(zhong)管(guan)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外觀整潔完(wan)好，有(you)可靠(kao)的防護裝置，記得索要發票。

播種機怎么用

播(bo)(bo)種(zhong)機在(zai)播(bo)(bo)種(zhong)時(shi)，應按照種(zhong)子(zi)(zi)的(de)特(te)(te)點(dian)，對其進行播(bo)(bo)種(zhong)。如播(bo)(bo)種(zhong)的(de)行距應該控制在(zai)20厘(li)米(mi)左右，不(bu)(bu)能過寬也不(bu)(bu)能過窄。播(bo)(bo)種(zhong)深度應控制在(zai)1.5—3.0厘(li)米(mi)，但是也要考慮(lv)到特(te)(te)殊情(qing)況，不(bu)(bu)同的(de)土壤(rang)播(bo)(bo)種(zhong)的(de)深度也不(bu)(bu)同，土壤(rang)偏旱(han)，播(bo)(bo)深就要略(lve)深一點(dian)，這樣(yang)可(ke)以防止種(zhong)子(zi)(zi)播(bo)(bo)淺，土壤(rang)過干(gan)而不(bu)(bu)能生(sheng)長(chang)。因此(ci)，農機手在(zai)播(bo)(bo)種(zhong)時(shi)，一定要充分考慮(lv)種(zhong)子(zi)(zi)、土壤(rang)等(deng)情(qing)況，確保(bao)種(zhong)子(zi)(zi)的(de)健康(kang)成長(chang)。
