播種機械工作原理

播(bo)種(zhong)機通過傳動(dong)系統帶動(dong)排種(zhong)器、排肥器，按要求種(zhong)肥量將(jiang)從種(zhong)肥箱進入排種(zhong)器和(he)(he)排肥器的種(zhong)子(zi)和(he)(he)肥料排到由開溝(gou)器開好的種(zhong)溝(gou)和(he)(he)肥溝(gou)里，隨后覆(fu)土(tu)器覆(fu)土(tu)，鎮(zhen)壓器壓實種(zhong)床，完(wan)成播(bo)種(zhong)作業。

播種機械的構造和工作過程

播種(zhong)機(ji)一般由種(zhong)子(zi)(zi)箱、排(pai)種(zhong)器、輸(shu)種(zhong)管、開(kai)溝(gou)器、覆(fu)土器、行走輪、轉動(dong)機(ji)構等組成。工作(zuo)時(shi)，開(kai)溝(gou)器在地上(shang)開(kai)出(chu)種(zhong)溝(gou)，種(zhong)子(zi)(zi)箱內(nei)的種(zhong)子(zi)(zi)由排(pai)種(zhong)器排(pai)出(chu)，經輸(shu)種(zhong)管落入種(zhong)溝(gou)，再由覆(fu)土器覆(fu)土完成播種(zhong)作(zuo)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(hao)，有可靠的防護裝置，記得索(suo)要發(fa)票。

播種機怎么用

播(bo)(bo)(bo)(bo)種(zhong)機在(zai)(zai)播(bo)(bo)(bo)(bo)種(zhong)時，應按照種(zhong)子(zi)(zi)的(de)特(te)點，對其進(jin)行(xing)播(bo)(bo)(bo)(bo)種(zhong)。如播(bo)(bo)(bo)(bo)種(zhong)的(de)行(xing)距應該控制(zhi)在(zai)(zai)20厘(li)米左右，不(bu)(bu)能(neng)(neng)過(guo)寬(kuan)也(ye)不(bu)(bu)能(neng)(neng)過(guo)窄。播(bo)(bo)(bo)(bo)種(zhong)深(shen)度應控制(zhi)在(zai)(zai)1.5—3.0厘(li)米，但是也(ye)要考(kao)(kao)慮到特(te)殊(shu)情況，不(bu)(bu)同的(de)土壤(rang)播(bo)(bo)(bo)(bo)種(zhong)的(de)深(shen)度也(ye)不(bu)(bu)同，土壤(rang)偏旱，播(bo)(bo)(bo)(bo)深(shen)就要略(lve)深(shen)一(yi)點，這樣可以(yi)防止種(zhong)子(zi)(zi)播(bo)(bo)(bo)(bo)淺，土壤(rang)過(guo)干而不(bu)(bu)能(neng)(neng)生長。因此，農機手在(zai)(zai)播(bo)(bo)(bo)(bo)種(zhong)時，一(yi)定要充分(fen)考(kao)(kao)慮種(zhong)子(zi)(zi)、土壤(rang)等情況，確保種(zhong)子(zi)(zi)的(de)健康成(cheng)長。
