播種機有哪些種類
播(bo)(bo)種(zhong)(zhong)機(ji)按種(zhong)(zhong)子播(bo)(bo)到種(zhong)(zhong)床的形狀可(ke)分(fen)(fen)為(wei)撒播(bo)(bo)機(ji)、條播(bo)(bo)機(ji)、穴播(bo)(bo)機(ji);按動(dong)力(li)可(ke)分(fen)(fen)為(wei)人力(li)播(bo)(bo)種(zhong)(zhong)機(ji)、畜(chu)力(li)播(bo)(bo)種(zhong)(zhong)機(ji)和機(ji)械播(bo)(bo)種(zhong)(zhong)機(ji);按排(pai)種(zhong)(zhong)器取排(pai)種(zhong)(zhong)原理可(ke)分(fen)(fen)為(wei)氣動(dong)式和機(ji)械式;按聯合作(zuo)業形式可(ke)分(fen)(fen)為(wei)旋(xuan)耕(geng)播(bo)(bo)種(zhong)(zhong)機(ji)、覆膜播(bo)(bo)種(zhong)(zhong)機(ji)、免耕(geng)播(bo)(bo)種(zhong)(zhong)機(ji)。
播種機械工作原理
播種(zhong)(zhong)機通過傳動(dong)系統(tong)帶動(dong)排(pai)(pai)種(zhong)(zhong)器(qi)(qi)、排(pai)(pai)肥(fei)(fei)器(qi)(qi),按(an)要求種(zhong)(zhong)肥(fei)(fei)量將從種(zhong)(zhong)肥(fei)(fei)箱進入排(pai)(pai)種(zhong)(zhong)器(qi)(qi)和(he)排(pai)(pai)肥(fei)(fei)器(qi)(qi)的(de)種(zhong)(zhong)子和(he)肥(fei)(fei)料排(pai)(pai)到由開(kai)溝(gou)(gou)器(qi)(qi)開(kai)好的(de)種(zhong)(zhong)溝(gou)(gou)和(he)肥(fei)(fei)溝(gou)(gou)里(li),隨后覆土(tu)(tu)器(qi)(qi)覆土(tu)(tu),鎮壓(ya)器(qi)(qi)壓(ya)實種(zhong)(zhong)床,完成播種(zhong)(zhong)作業。
播種機械的構造和工作過程
播種機一般(ban)由種子(zi)(zi)箱(xiang)、排(pai)(pai)種器(qi)、輸(shu)種管(guan)、開溝(gou)器(qi)、覆(fu)土器(qi)、行走輪、轉動機構等(deng)組成。工作時,開溝(gou)器(qi)在地(di)上開出(chu)種溝(gou),種子(zi)(zi)箱(xiang)內的(de)種子(zi)(zi)由排(pai)(pai)種器(qi)排(pai)(pai)出(chu),經(jing)輸(shu)種管(guan)落入種溝(gou),再(zai)由覆(fu)土器(qi)覆(fu)土完成播種作業(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,有可(ke)靠的(de)防護裝(zhuang)置,記得索(suo)要(yao)發票。
播種機怎么用
播(bo)(bo)(bo)(bo)種機(ji)在播(bo)(bo)(bo)(bo)種時,應(ying)按照(zhao)種子(zi)的(de)特點(dian),對其進行播(bo)(bo)(bo)(bo)種。如播(bo)(bo)(bo)(bo)種的(de)行距(ju)應(ying)該(gai)控制(zhi)在20厘米(mi)左(zuo)右,不(bu)(bu)(bu)能過寬(kuan)也(ye)(ye)不(bu)(bu)(bu)能過窄。播(bo)(bo)(bo)(bo)種深度應(ying)控制(zhi)在1.5—3.0厘米(mi),但是也(ye)(ye)要(yao)考(kao)慮(lv)到特殊(shu)情況(kuang)(kuang),不(bu)(bu)(bu)同(tong)的(de)土壤(rang)播(bo)(bo)(bo)(bo)種的(de)深度也(ye)(ye)不(bu)(bu)(bu)同(tong),土壤(rang)偏旱,播(bo)(bo)(bo)(bo)深就要(yao)略深一點(dian),這(zhe)樣可以防止種子(zi)播(bo)(bo)(bo)(bo)淺,土壤(rang)過干而不(bu)(bu)(bu)能生長。因(yin)此,農(nong)機(ji)手在播(bo)(bo)(bo)(bo)種時,一定(ding)要(yao)充分考(kao)慮(lv)種子(zi)、土壤(rang)等(deng)情況(kuang)(kuang),確(que)保(bao)種子(zi)的(de)健(jian)康成長。
