播種機有哪些種類
播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)按(an)種(zhong)子(zi)播(bo)(bo)(bo)(bo)到種(zhong)床的形狀可(ke)分為(wei)撒播(bo)(bo)(bo)(bo)機(ji)(ji)(ji)、條播(bo)(bo)(bo)(bo)機(ji)(ji)(ji)、穴播(bo)(bo)(bo)(bo)機(ji)(ji)(ji);按(an)動力可(ke)分為(wei)人力播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)、畜(chu)力播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)和機(ji)(ji)(ji)械(xie)(xie)播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji);按(an)排種(zhong)器取排種(zhong)原理可(ke)分為(wei)氣動式和機(ji)(ji)(ji)械(xie)(xie)式;按(an)聯(lian)合(he)作業形式可(ke)分為(wei)旋耕播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)、覆膜播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)、免(mian)耕播(bo)(bo)(bo)(bo)種(zhong)機(ji)(ji)(ji)。
播種機械工作原理
播(bo)種(zhong)機通過傳動系(xi)統帶動排(pai)(pai)種(zhong)器(qi)(qi)(qi)、排(pai)(pai)肥(fei)(fei)器(qi)(qi)(qi),按(an)要求種(zhong)肥(fei)(fei)量將(jiang)從(cong)種(zhong)肥(fei)(fei)箱進(jin)入排(pai)(pai)種(zhong)器(qi)(qi)(qi)和排(pai)(pai)肥(fei)(fei)器(qi)(qi)(qi)的種(zhong)子和肥(fei)(fei)料排(pai)(pai)到由開溝(gou)器(qi)(qi)(qi)開好的種(zhong)溝(gou)和肥(fei)(fei)溝(gou)里,隨(sui)后覆土器(qi)(qi)(qi)覆土,鎮壓器(qi)(qi)(qi)壓實(shi)種(zhong)床(chuang),完成播(bo)種(zhong)作業。
播種機械的構造和工作過程
播(bo)種(zhong)(zhong)機一般由種(zhong)(zhong)子箱(xiang)、排(pai)(pai)種(zhong)(zhong)器(qi)(qi)、輸種(zhong)(zhong)管、開溝(gou)(gou)器(qi)(qi)、覆土器(qi)(qi)、行走輪、轉動(dong)機構等(deng)組成(cheng)。工作時,開溝(gou)(gou)器(qi)(qi)在地(di)上(shang)開出種(zhong)(zhong)溝(gou)(gou),種(zhong)(zhong)子箱(xiang)內的種(zhong)(zhong)子由排(pai)(pai)種(zhong)(zhong)器(qi)(qi)排(pai)(pai)出,經輸種(zhong)(zhong)管落入種(zhong)(zhong)溝(gou)(gou),再由覆土器(qi)(qi)覆土完成(cheng)播(bo)種(zhong)(zhong)作業(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(wai)觀整潔完好(hao),有(you)可靠的防護裝置,記得索要發票。
播種機怎么用
播(bo)種(zhong)(zhong)(zhong)機(ji)在播(bo)種(zhong)(zhong)(zhong)時(shi),應(ying)(ying)按(an)照種(zhong)(zhong)(zhong)子(zi)(zi)的特(te)點,對其進(jin)行(xing)播(bo)種(zhong)(zhong)(zhong)。如播(bo)種(zhong)(zhong)(zhong)的行(xing)距應(ying)(ying)該(gai)控制在20厘(li)米左右,不(bu)能過(guo)寬也不(bu)能過(guo)窄。播(bo)種(zhong)(zhong)(zhong)深度(du)(du)應(ying)(ying)控制在1.5—3.0厘(li)米,但是(shi)也要考慮到(dao)特(te)殊情況(kuang),不(bu)同(tong)的土(tu)壤(rang)(rang)播(bo)種(zhong)(zhong)(zhong)的深度(du)(du)也不(bu)同(tong),土(tu)壤(rang)(rang)偏旱,播(bo)深就要略深一點,這樣可以防止種(zhong)(zhong)(zhong)子(zi)(zi)播(bo)淺,土(tu)壤(rang)(rang)過(guo)干(gan)而不(bu)能生長。因(yin)此(ci),農機(ji)手在播(bo)種(zhong)(zhong)(zhong)時(shi),一定要充分考慮種(zhong)(zhong)(zhong)子(zi)(zi)、土(tu)壤(rang)(rang)等(deng)情況(kuang),確保種(zhong)(zhong)(zhong)子(zi)(zi)的健(jian)康成(cheng)長。
