播種機有哪些種類

播(bo)種(zhong)(zhong)機(ji)(ji)按(an)種(zhong)(zhong)子播(bo)到種(zhong)(zhong)床的形狀可分(fen)(fen)為(wei)撒播(bo)機(ji)(ji)、條(tiao)播(bo)機(ji)(ji)、穴播(bo)機(ji)(ji)；按(an)動力可分(fen)(fen)為(wei)人力播(bo)種(zhong)(zhong)機(ji)(ji)、畜(chu)力播(bo)種(zhong)(zhong)機(ji)(ji)和(he)(he)機(ji)(ji)械播(bo)種(zhong)(zhong)機(ji)(ji)；按(an)排(pai)種(zhong)(zhong)器取排(pai)種(zhong)(zhong)原理可分(fen)(fen)為(wei)氣動式(shi)和(he)(he)機(ji)(ji)械式(shi)；按(an)聯合作業(ye)形式(shi)可分(fen)(fen)為(wei)旋(xuan)耕播(bo)種(zhong)(zhong)機(ji)(ji)、覆膜播(bo)種(zhong)(zhong)機(ji)(ji)、免耕播(bo)種(zhong)(zhong)機(ji)(ji)。

播種機械工作原理

播(bo)(bo)種(zhong)機通過(guo)傳動系統帶(dai)動排(pai)(pai)(pai)種(zhong)器、排(pai)(pai)(pai)肥(fei)(fei)器，按(an)要求種(zhong)肥(fei)(fei)量將從種(zhong)肥(fei)(fei)箱進(jin)入排(pai)(pai)(pai)種(zhong)器和排(pai)(pai)(pai)肥(fei)(fei)器的(de)種(zhong)子和肥(fei)(fei)料排(pai)(pai)(pai)到由開溝器開好的(de)種(zhong)溝和肥(fei)(fei)溝里，隨后(hou)覆土器覆土，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)機一(yi)般由種(zhong)(zhong)(zhong)子(zi)箱、排(pai)(pai)(pai)種(zhong)(zhong)(zhong)器(qi)、輸(shu)種(zhong)(zhong)(zhong)管、開(kai)溝器(qi)、覆土器(qi)、行走輪、轉動機構等組成(cheng)。工作時(shi)，開(kai)溝器(qi)在地上開(kai)出(chu)種(zhong)(zhong)(zhong)溝，種(zhong)(zhong)(zhong)子(zi)箱內的種(zhong)(zhong)(zhong)子(zi)由排(pai)(pai)(pai)種(zhong)(zhong)(zhong)器(qi)排(pai)(pai)(pai)出(chu)，經輸(shu)種(zhong)(zhong)(zhong)管落(luo)入(ru)種(zhong)(zhong)(zhong)溝，再由覆土器(qi)覆土完成(cheng)播種(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(wai)觀(guan)整潔完好，有可靠的防護(hu)裝置(zhi)，記得索(suo)要發票。

播種機怎么用

播(bo)(bo)種(zhong)(zhong)機(ji)在播(bo)(bo)種(zhong)(zhong)時，應按照種(zhong)(zhong)子的特點，對(dui)其(qi)進行播(bo)(bo)種(zhong)(zhong)。如播(bo)(bo)種(zhong)(zhong)的行距應該控制在20厘(li)米左右，不(bu)(bu)能過寬也不(bu)(bu)能過窄。播(bo)(bo)種(zhong)(zhong)深度(du)應控制在1.5—3.0厘(li)米，但是也要考慮(lv)到(dao)特殊情(qing)(qing)況，不(bu)(bu)同的土(tu)壤(rang)(rang)播(bo)(bo)種(zhong)(zhong)的深度(du)也不(bu)(bu)同，土(tu)壤(rang)(rang)偏旱，播(bo)(bo)深就(jiu)要略深一點，這(zhe)樣可以防止種(zhong)(zhong)子播(bo)(bo)淺，土(tu)壤(rang)(rang)過干而(er)不(bu)(bu)能生長(chang)。因此，農(nong)機(ji)手(shou)在播(bo)(bo)種(zhong)(zhong)時，一定要充分考慮(lv)種(zhong)(zhong)子、土(tu)壤(rang)(rang)等(deng)情(qing)(qing)況，確保種(zhong)(zhong)子的健康成長(chang)。
