播種機械工作原理

播(bo)種(zhong)機通過傳動(dong)系統帶動(dong)排(pai)種(zhong)器(qi)(qi)、排(pai)肥(fei)(fei)(fei)器(qi)(qi)，按要求種(zhong)肥(fei)(fei)(fei)量將從種(zhong)肥(fei)(fei)(fei)箱進入排(pai)種(zhong)器(qi)(qi)和(he)排(pai)肥(fei)(fei)(fei)器(qi)(qi)的種(zhong)子(zi)和(he)肥(fei)(fei)(fei)料(liao)排(pai)到由開(kai)溝(gou)器(qi)(qi)開(kai)好的種(zhong)溝(gou)和(he)肥(fei)(fei)(fei)溝(gou)里(li)，隨后(hou)覆(fu)土(tu)器(qi)(qi)覆(fu)土(tu)，鎮壓器(qi)(qi)壓實種(zhong)床，完成播(bo)種(zhong)作業。

播種機械的構造和工作過程

播(bo)種(zhong)(zhong)(zhong)機一般由種(zhong)(zhong)(zhong)子箱、排種(zhong)(zhong)(zhong)器(qi)、輸種(zhong)(zhong)(zhong)管、開(kai)溝器(qi)、覆(fu)(fu)土(tu)(tu)器(qi)、行走(zou)輪(lun)、轉(zhuan)動(dong)機構(gou)等組(zu)成(cheng)。工作時，開(kai)溝器(qi)在地(di)上開(kai)出種(zhong)(zhong)(zhong)溝，種(zhong)(zhong)(zhong)子箱內的(de)種(zhong)(zhong)(zhong)子由排種(zhong)(zhong)(zhong)器(qi)排出，經輸種(zhong)(zhong)(zhong)管落入(ru)種(zhong)(zhong)(zhong)溝，再由覆(fu)(fu)土(tu)(tu)器(qi)覆(fu)(fu)土(tu)(tu)完成(cheng)播(bo)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觀整(zheng)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)機在播(bo)種(zhong)(zhong)(zhong)時(shi)，應按照種(zhong)(zhong)(zhong)子(zi)(zi)的(de)特點，對其(qi)進行播(bo)種(zhong)(zhong)(zhong)。如播(bo)種(zhong)(zhong)(zhong)的(de)行距應該控制(zhi)(zhi)在20厘(li)(li)米(mi)左右，不(bu)(bu)(bu)(bu)能過寬也不(bu)(bu)(bu)(bu)能過窄。播(bo)種(zhong)(zhong)(zhong)深(shen)度應控制(zhi)(zhi)在1.5—3.0厘(li)(li)米(mi)，但(dan)是也要(yao)考慮到特殊(shu)情況，不(bu)(bu)(bu)(bu)同(tong)的(de)土(tu)壤(rang)播(bo)種(zhong)(zhong)(zhong)的(de)深(shen)度也不(bu)(bu)(bu)(bu)同(tong)，土(tu)壤(rang)偏(pian)旱，播(bo)深(shen)就(jiu)要(yao)略(lve)深(shen)一點，這樣可以防止(zhi)種(zhong)(zhong)(zhong)子(zi)(zi)播(bo)淺，土(tu)壤(rang)過干而不(bu)(bu)(bu)(bu)能生長(chang)。因此，農機手在播(bo)種(zhong)(zhong)(zhong)時(shi)，一定要(yao)充分考慮種(zhong)(zhong)(zhong)子(zi)(zi)、土(tu)壤(rang)等情況，確保(bao)種(zhong)(zhong)(zhong)子(zi)(zi)的(de)健康成(cheng)長(chang)。
