播種機有哪些種類

播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)按(an)種(zhong)(zhong)(zhong)(zhong)(zhong)子播(bo)到種(zhong)(zhong)(zhong)(zhong)(zhong)床的(de)形狀可(ke)分為(wei)(wei)撒(sa)播(bo)機(ji)、條(tiao)播(bo)機(ji)、穴播(bo)機(ji)；按(an)動(dong)力(li)可(ke)分為(wei)(wei)人力(li)播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)、畜力(li)播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)和機(ji)械播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)；按(an)排(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)器取排(pai)種(zhong)(zhong)(zhong)(zhong)(zhong)原理可(ke)分為(wei)(wei)氣動(dong)式(shi)和機(ji)械式(shi)；按(an)聯合作業形式(shi)可(ke)分為(wei)(wei)旋耕播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)、覆膜(mo)播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)、免耕播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)。

播種機械工作原理

播(bo)種機通(tong)過傳動系統(tong)帶動排(pai)(pai)種器、排(pai)(pai)肥(fei)(fei)(fei)器，按要求(qiu)種肥(fei)(fei)(fei)量(liang)將從種肥(fei)(fei)(fei)箱進入排(pai)(pai)種器和排(pai)(pai)肥(fei)(fei)(fei)器的(de)種子和肥(fei)(fei)(fei)料排(pai)(pai)到由開溝器開好的(de)種溝和肥(fei)(fei)(fei)溝里，隨后覆(fu)(fu)土器覆(fu)(fu)土，鎮(zhen)壓器壓實(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(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)機一般由(you)種(zhong)(zhong)(zhong)(zhong)(zhong)子箱、排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)、輸(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)管、開溝(gou)(gou)器(qi)、覆土器(qi)、行走(zou)輪、轉(zhuan)動機構等(deng)組成。工作(zuo)時，開溝(gou)(gou)器(qi)在地上(shang)開出(chu)種(zhong)(zhong)(zhong)(zhong)(zhong)溝(gou)(gou)，種(zhong)(zhong)(zhong)(zhong)(zhong)子箱內的種(zhong)(zhong)(zhong)(zhong)(zhong)子由(you)排種(zhong)(zhong)(zhong)(zhong)(zhong)器(qi)排出(chu)，經輸(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)管落入種(zhong)(zhong)(zhong)(zhong)(zhong)溝(gou)(gou)，再(zai)由(you)覆土器(qi)覆土完成播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)作(zuo)業(ye)。

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(wan)好，有可靠的防護(hu)裝置(zhi)，記(ji)得索要(yao)發票。

播種機怎么用

播(bo)(bo)(bo)種(zhong)(zhong)機在(zai)(zai)播(bo)(bo)(bo)種(zhong)(zhong)時，應按(an)照種(zhong)(zhong)子(zi)(zi)的(de)(de)(de)(de)特點，對其(qi)進行(xing)播(bo)(bo)(bo)種(zhong)(zhong)。如播(bo)(bo)(bo)種(zhong)(zhong)的(de)(de)(de)(de)行(xing)距應該控制(zhi)在(zai)(zai)20厘米(mi)左(zuo)右，不能(neng)過(guo)寬也不能(neng)過(guo)窄。播(bo)(bo)(bo)種(zhong)(zhong)深(shen)度(du)應控制(zhi)在(zai)(zai)1.5—3.0厘米(mi)，但是也要(yao)考(kao)(kao)慮到(dao)特殊情況(kuang)，不同的(de)(de)(de)(de)土(tu)(tu)壤(rang)(rang)播(bo)(bo)(bo)種(zhong)(zhong)的(de)(de)(de)(de)深(shen)度(du)也不同，土(tu)(tu)壤(rang)(rang)偏(pian)旱，播(bo)(bo)(bo)深(shen)就要(yao)略深(shen)一點，這樣(yang)可(ke)以防止種(zhong)(zhong)子(zi)(zi)播(bo)(bo)(bo)淺，土(tu)(tu)壤(rang)(rang)過(guo)干而(er)不能(neng)生長。因此(ci)，農機手在(zai)(zai)播(bo)(bo)(bo)種(zhong)(zhong)時，一定要(yao)充(chong)分考(kao)(kao)慮種(zhong)(zhong)子(zi)(zi)、土(tu)(tu)壤(rang)(rang)等情況(kuang)，確保(bao)種(zhong)(zhong)子(zi)(zi)的(de)(de)(de)(de)健康(kang)成長。
