播種機械工作原理

播種(zhong)(zhong)(zhong)機通過(guo)傳動(dong)系(xi)統(tong)帶動(dong)排種(zhong)(zhong)(zhong)器(qi)、排肥(fei)器(qi)，按要求種(zhong)(zhong)(zhong)肥(fei)量將從(cong)種(zhong)(zhong)(zhong)肥(fei)箱進入排種(zhong)(zhong)(zhong)器(qi)和(he)排肥(fei)器(qi)的種(zhong)(zhong)(zhong)子和(he)肥(fei)料排到由開(kai)(kai)溝器(qi)開(kai)(kai)好的種(zhong)(zhong)(zhong)溝和(he)肥(fei)溝里(li)，隨(sui)后(hou)覆土器(qi)覆土，鎮壓(ya)器(qi)壓(ya)實種(zhong)(zhong)(zhong)床，完(wan)成播種(zhong)(zhong)(zhong)作業。

播種機械的構造和工作過程

播種(zhong)(zhong)(zhong)(zhong)機一般(ban)由(you)種(zhong)(zhong)(zhong)(zhong)子(zi)箱、排種(zhong)(zhong)(zhong)(zhong)器、輸種(zhong)(zhong)(zhong)(zhong)管、開溝器、覆(fu)土器、行(xing)走(zou)輪(lun)、轉動(dong)機構等組成(cheng)。工作(zuo)時(shi)，開溝器在地(di)上開出(chu)(chu)種(zhong)(zhong)(zhong)(zhong)溝，種(zhong)(zhong)(zhong)(zhong)子(zi)箱內(nei)的種(zhong)(zhong)(zhong)(zhong)子(zi)由(you)排種(zhong)(zhong)(zhong)(zhong)器排出(chu)(chu)，經輸種(zhong)(zhong)(zhong)(zhong)管落入種(zhong)(zhong)(zhong)(zhong)溝，再由(you)覆(fu)土器覆(fu)土完(wan)成(cheng)播種(zhong)(zhong)(zhong)(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潔(jie)完好，有可靠的防護裝置，記(ji)得索(suo)要發票。

播種機怎么用

播(bo)(bo)種(zhong)(zhong)機在(zai)播(bo)(bo)種(zhong)(zhong)時(shi)，應按照種(zhong)(zhong)子的(de)特點，對其進(jin)行播(bo)(bo)種(zhong)(zhong)。如播(bo)(bo)種(zhong)(zhong)的(de)行距應該(gai)控(kong)制在(zai)20厘(li)米左右，不能(neng)過(guo)(guo)寬也(ye)不能(neng)過(guo)(guo)窄。播(bo)(bo)種(zhong)(zhong)深(shen)度應控(kong)制在(zai)1.5—3.0厘(li)米，但是也(ye)要(yao)考慮到特殊情況，不同的(de)土(tu)壤(rang)(rang)播(bo)(bo)種(zhong)(zhong)的(de)深(shen)度也(ye)不同，土(tu)壤(rang)(rang)偏旱，播(bo)(bo)深(shen)就要(yao)略深(shen)一(yi)(yi)點，這樣可以防(fang)止(zhi)種(zhong)(zhong)子播(bo)(bo)淺，土(tu)壤(rang)(rang)過(guo)(guo)干(gan)而不能(neng)生長。因此，農(nong)機手(shou)在(zai)播(bo)(bo)種(zhong)(zhong)時(shi)，一(yi)(yi)定要(yao)充分考慮種(zhong)(zhong)子、土(tu)壤(rang)(rang)等情況，確保種(zhong)(zhong)子的(de)健康(kang)成長。
