播種機有哪些種類

播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)按(an)種(zhong)(zhong)(zhong)(zhong)子播(bo)到種(zhong)(zhong)(zhong)(zhong)床(chuang)的(de)形狀可分(fen)為(wei)(wei)撒播(bo)機(ji)、條播(bo)機(ji)、穴(xue)播(bo)機(ji)；按(an)動(dong)力可分(fen)為(wei)(wei)人力播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)、畜力播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)和機(ji)械(xie)播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)；按(an)排種(zhong)(zhong)(zhong)(zhong)器取排種(zhong)(zhong)(zhong)(zhong)原理(li)可分(fen)為(wei)(wei)氣動(dong)式(shi)和機(ji)械(xie)式(shi)；按(an)聯合作業形式(shi)可分(fen)為(wei)(wei)旋(xuan)耕播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)、覆(fu)膜(mo)播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)、免耕播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)。

播種機械工作原理

播(bo)種機通過傳動系統帶(dai)動排種器(qi)(qi)(qi)、排肥器(qi)(qi)(qi)，按(an)要求(qiu)種肥量(liang)將從(cong)種肥箱進入排種器(qi)(qi)(qi)和排肥器(qi)(qi)(qi)的種子(zi)和肥料排到由開溝(gou)器(qi)(qi)(qi)開好(hao)的種溝(gou)和肥溝(gou)里，隨(sui)后覆土器(qi)(qi)(qi)覆土，鎮壓(ya)器(qi)(qi)(qi)壓(ya)實(shi)種床，完(wan)成(cheng)播(bo)種作業。

播種機械的構造和工作過程

播種(zhong)(zhong)(zhong)(zhong)(zhong)機一般由種(zhong)(zhong)(zhong)(zhong)(zhong)子箱、排(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)、輸種(zhong)(zhong)(zhong)(zhong)(zhong)管、開(kai)(kai)溝器(qi)、覆土器(qi)、行走輪(lun)、轉動機構等組成(cheng)。工作(zuo)時，開(kai)(kai)溝器(qi)在(zai)地(di)上開(kai)(kai)出種(zhong)(zhong)(zhong)(zhong)(zhong)溝，種(zhong)(zhong)(zhong)(zhong)(zhong)子箱內的種(zhong)(zhong)(zhong)(zhong)(zhong)子由排(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)排(pai)出，經輸種(zhong)(zhong)(zhong)(zhong)(zhong)管落入種(zhong)(zhong)(zhong)(zhong)(zhong)溝，再由覆土器(qi)覆土完成(cheng)播種(zhong)(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(wai)觀整(zheng)潔完好，有可靠的防護裝置，記(ji)得(de)索要發票。

播種機怎么用

播(bo)(bo)(bo)(bo)(bo)種(zhong)(zhong)機(ji)在播(bo)(bo)(bo)(bo)(bo)種(zhong)(zhong)時(shi)，應按照(zhao)種(zhong)(zhong)子(zi)(zi)(zi)的(de)特點，對其進行(xing)播(bo)(bo)(bo)(bo)(bo)種(zhong)(zhong)。如播(bo)(bo)(bo)(bo)(bo)種(zhong)(zhong)的(de)行(xing)距應該控制在20厘米(mi)左(zuo)右(you)，不能(neng)過(guo)(guo)寬也不能(neng)過(guo)(guo)窄。播(bo)(bo)(bo)(bo)(bo)種(zhong)(zhong)深(shen)(shen)度應控制在1.5—3.0厘米(mi)，但(dan)是也要考(kao)慮(lv)到特殊情況，不同(tong)的(de)土(tu)壤(rang)播(bo)(bo)(bo)(bo)(bo)種(zhong)(zhong)的(de)深(shen)(shen)度也不同(tong)，土(tu)壤(rang)偏旱(han)，播(bo)(bo)(bo)(bo)(bo)深(shen)(shen)就要略深(shen)(shen)一點，這樣(yang)可以防(fang)止種(zhong)(zhong)子(zi)(zi)(zi)播(bo)(bo)(bo)(bo)(bo)淺，土(tu)壤(rang)過(guo)(guo)干而不能(neng)生長。因此，農機(ji)手在播(bo)(bo)(bo)(bo)(bo)種(zhong)(zhong)時(shi)，一定要充分考(kao)慮(lv)種(zhong)(zhong)子(zi)(zi)(zi)、土(tu)壤(rang)等(deng)情況，確(que)保(bao)種(zhong)(zhong)子(zi)(zi)(zi)的(de)健康成長。
