播種機械工作原理

播(bo)種(zhong)(zhong)機通過傳動(dong)(dong)系(xi)統帶動(dong)(dong)排種(zhong)(zhong)器(qi)(qi)、排肥器(qi)(qi)，按要求種(zhong)(zhong)肥量將從種(zhong)(zhong)肥箱(xiang)進(jin)入排種(zhong)(zhong)器(qi)(qi)和排肥器(qi)(qi)的(de)種(zhong)(zhong)子和肥料排到由(you)開(kai)溝(gou)器(qi)(qi)開(kai)好的(de)種(zhong)(zhong)溝(gou)和肥溝(gou)里(li)，隨(sui)后覆土器(qi)(qi)覆土，鎮壓器(qi)(qi)壓實(shi)種(zhong)(zhong)床，完成播(bo)種(zhong)(zhong)作(zuo)業。

播種機械的構造和工作過程

播種(zhong)(zhong)(zhong)(zhong)機一般由(you)種(zhong)(zhong)(zhong)(zhong)子箱(xiang)、排(pai)種(zhong)(zhong)(zhong)(zhong)器(qi)、輸種(zhong)(zhong)(zhong)(zhong)管、開(kai)溝(gou)(gou)器(qi)、覆土器(qi)、行走輪、轉動機構等組成(cheng)。工作時，開(kai)溝(gou)(gou)器(qi)在地(di)上(shang)開(kai)出(chu)種(zhong)(zhong)(zhong)(zhong)溝(gou)(gou)，種(zhong)(zhong)(zhong)(zhong)子箱(xiang)內的種(zhong)(zhong)(zhong)(zhong)子由(you)排(pai)種(zhong)(zhong)(zhong)(zhong)器(qi)排(pai)出(chu)，經輸種(zhong)(zhong)(zhong)(zhong)管落入種(zhong)(zhong)(zhong)(zhong)溝(gou)(gou)，再(zai)由(you)覆土器(qi)覆土完成(cheng)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整潔完好，有可靠的防護裝置，記得索要發票。

播種機怎么用

播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)在播(bo)種(zhong)(zhong)(zhong)(zhong)時，應(ying)按照種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)的(de)(de)特(te)點(dian)，對其進行(xing)播(bo)種(zhong)(zhong)(zhong)(zhong)。如播(bo)種(zhong)(zhong)(zhong)(zhong)的(de)(de)行(xing)距應(ying)該控制在20厘米左(zuo)右(you)，不(bu)能過寬也不(bu)能過窄。播(bo)種(zhong)(zhong)(zhong)(zhong)深度應(ying)控制在1.5—3.0厘米，但是也要(yao)考慮(lv)到特(te)殊(shu)情(qing)(qing)況，不(bu)同(tong)的(de)(de)土壤(rang)播(bo)種(zhong)(zhong)(zhong)(zhong)的(de)(de)深度也不(bu)同(tong)，土壤(rang)偏旱(han)，播(bo)深就要(yao)略深一(yi)點(dian)，這樣可(ke)以防止種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)播(bo)淺，土壤(rang)過干(gan)而不(bu)能生長。因(yin)此，農(nong)機(ji)手(shou)在播(bo)種(zhong)(zhong)(zhong)(zhong)時，一(yi)定要(yao)充(chong)分考慮(lv)種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)、土壤(rang)等情(qing)(qing)況，確保種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)的(de)(de)健(jian)康成(cheng)長。
