播種機械工作原理

播種機通過傳動系統帶動排種器(qi)、排肥(fei)(fei)(fei)器(qi)，按(an)要求種肥(fei)(fei)(fei)量將從種肥(fei)(fei)(fei)箱進入(ru)排種器(qi)和排肥(fei)(fei)(fei)器(qi)的種子和肥(fei)(fei)(fei)料排到由(you)開溝器(qi)開好的種溝和肥(fei)(fei)(fei)溝里，隨后覆土器(qi)覆土，鎮壓器(qi)壓實(shi)種床，完成播種作業。

播種機械的構造和工作過程

播種(zhong)(zhong)機一般(ban)由(you)種(zhong)(zhong)子(zi)箱(xiang)、排(pai)種(zhong)(zhong)器(qi)、輸種(zhong)(zhong)管(guan)、開溝(gou)器(qi)、覆(fu)土器(qi)、行走輪(lun)、轉動機構等組成。工作(zuo)時(shi)，開溝(gou)器(qi)在地上開出種(zhong)(zhong)溝(gou)，種(zhong)(zhong)子(zi)箱(xiang)內的種(zhong)(zhong)子(zi)由(you)排(pai)種(zhong)(zhong)器(qi)排(pai)出，經(jing)輸種(zhong)(zhong)管(guan)落入(ru)種(zhong)(zhong)溝(gou)，再由(you)覆(fu)土器(qi)覆(fu)土完成播種(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完好(hao)，有可靠的(de)防護裝置，記得索(suo)要發票。

播種機怎么用

播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)(ji)在(zai)播(bo)種(zhong)(zhong)(zhong)(zhong)時，應(ying)按照(zhao)種(zhong)(zhong)(zhong)(zhong)子(zi)的(de)特點(dian)，對其(qi)進(jin)行播(bo)種(zhong)(zhong)(zhong)(zhong)。如播(bo)種(zhong)(zhong)(zhong)(zhong)的(de)行距應(ying)該(gai)控(kong)制在(zai)20厘米左右，不(bu)(bu)能過(guo)寬也不(bu)(bu)能過(guo)窄(zhai)。播(bo)種(zhong)(zhong)(zhong)(zhong)深度應(ying)控(kong)制在(zai)1.5—3.0厘米，但是也要考慮(lv)到(dao)特殊情(qing)(qing)況(kuang)，不(bu)(bu)同的(de)土(tu)壤播(bo)種(zhong)(zhong)(zhong)(zhong)的(de)深度也不(bu)(bu)同，土(tu)壤偏旱，播(bo)深就要略深一(yi)(yi)點(dian)，這樣可(ke)以防止種(zhong)(zhong)(zhong)(zhong)子(zi)播(bo)淺，土(tu)壤過(guo)干而不(bu)(bu)能生長(chang)。因(yin)此，農(nong)機(ji)(ji)手在(zai)播(bo)種(zhong)(zhong)(zhong)(zhong)時，一(yi)(yi)定要充分考慮(lv)種(zhong)(zhong)(zhong)(zhong)子(zi)、土(tu)壤等(deng)情(qing)(qing)況(kuang)，確保種(zhong)(zhong)(zhong)(zhong)子(zi)的(de)健康成(cheng)長(chang)。
