播種機有哪些種類

播(bo)(bo)(bo)種(zhong)(zhong)機(ji)(ji)按種(zhong)(zhong)子播(bo)(bo)(bo)到種(zhong)(zhong)床的形(xing)狀可分為(wei)撒(sa)播(bo)(bo)(bo)機(ji)(ji)、條播(bo)(bo)(bo)機(ji)(ji)、穴播(bo)(bo)(bo)機(ji)(ji)；按動力可分為(wei)人力播(bo)(bo)(bo)種(zhong)(zhong)機(ji)(ji)、畜(chu)力播(bo)(bo)(bo)種(zhong)(zhong)機(ji)(ji)和機(ji)(ji)械播(bo)(bo)(bo)種(zhong)(zhong)機(ji)(ji)；按排種(zhong)(zhong)器取排種(zhong)(zhong)原(yuan)理(li)可分為(wei)氣動式(shi)和機(ji)(ji)械式(shi)；按聯合作(zuo)業形(xing)式(shi)可分為(wei)旋耕播(bo)(bo)(bo)種(zhong)(zhong)機(ji)(ji)、覆膜播(bo)(bo)(bo)種(zhong)(zhong)機(ji)(ji)、免耕播(bo)(bo)(bo)種(zhong)(zhong)機(ji)(ji)。

播種機械工作原理

播(bo)種(zhong)(zhong)機通過傳動系(xi)統(tong)帶動排種(zhong)(zhong)器(qi)(qi)、排肥(fei)(fei)器(qi)(qi)，按要(yao)求(qiu)種(zhong)(zhong)肥(fei)(fei)量將從(cong)種(zhong)(zhong)肥(fei)(fei)箱進入(ru)排種(zhong)(zhong)器(qi)(qi)和排肥(fei)(fei)器(qi)(qi)的種(zhong)(zhong)子和肥(fei)(fei)料排到由開(kai)(kai)溝器(qi)(qi)開(kai)(kai)好(hao)的種(zhong)(zhong)溝和肥(fei)(fei)溝里，隨后覆土(tu)器(qi)(qi)覆土(tu)，鎮壓(ya)器(qi)(qi)壓(ya)實種(zhong)(zhong)床(chuang)，完成(cheng)播(bo)種(zhong)(zhong)作業。

播種機械的構造和工作過程

播(bo)種(zhong)機一般(ban)由(you)種(zhong)子(zi)(zi)箱、排(pai)種(zhong)器、輸種(zhong)管、開溝器、覆土(tu)器、行走輪、轉動(dong)機構等(deng)組成(cheng)。工作時，開溝器在地上開出(chu)種(zhong)溝，種(zhong)子(zi)(zi)箱內的種(zhong)子(zi)(zi)由(you)排(pai)種(zhong)器排(pai)出(chu)，經輸種(zhong)管落入種(zhong)溝，再(zai)由(you)覆土(tu)器覆土(tu)完成(cheng)播(bo)種(zhong)作業(ye)。

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)可靠的防護裝置，記得(de)索要發票。

播種機怎么用

播種(zhong)機在(zai)播種(zhong)時(shi)，應(ying)按照種(zhong)子的(de)(de)特(te)(te)點(dian)，對其進行播種(zhong)。如播種(zhong)的(de)(de)行距應(ying)該控制(zhi)在(zai)20厘米左右，不(bu)能過寬也不(bu)能過窄。播種(zhong)深度(du)應(ying)控制(zhi)在(zai)1.5—3.0厘米，但是也要考慮(lv)到特(te)(te)殊情(qing)況，不(bu)同的(de)(de)土壤(rang)播種(zhong)的(de)(de)深度(du)也不(bu)同，土壤(rang)偏旱，播深就要略深一點(dian)，這樣可(ke)以(yi)防止種(zhong)子播淺，土壤(rang)過干(gan)而不(bu)能生長。因此，農機手在(zai)播種(zhong)時(shi)，一定要充分考慮(lv)種(zhong)子、土壤(rang)等情(qing)況，確保種(zhong)子的(de)(de)健康成長。
