播種機有哪些種類

播(bo)種(zhong)(zhong)機(ji)(ji)(ji)按種(zhong)(zhong)子播(bo)到(dao)種(zhong)(zhong)床的形(xing)狀可(ke)分為(wei)撒播(bo)機(ji)(ji)(ji)、條播(bo)機(ji)(ji)(ji)、穴播(bo)機(ji)(ji)(ji)；按動(dong)力可(ke)分為(wei)人(ren)力播(bo)種(zhong)(zhong)機(ji)(ji)(ji)、畜力播(bo)種(zhong)(zhong)機(ji)(ji)(ji)和機(ji)(ji)(ji)械播(bo)種(zhong)(zhong)機(ji)(ji)(ji)；按排種(zhong)(zhong)器取排種(zhong)(zhong)原理可(ke)分為(wei)氣動(dong)式和機(ji)(ji)(ji)械式；按聯合作業(ye)形(xing)式可(ke)分為(wei)旋耕(geng)(geng)播(bo)種(zhong)(zhong)機(ji)(ji)(ji)、覆膜播(bo)種(zhong)(zhong)機(ji)(ji)(ji)、免(mian)耕(geng)(geng)播(bo)種(zhong)(zhong)機(ji)(ji)(ji)。

播種機械工作原理

播種(zhong)(zhong)機通過傳動(dong)系統帶(dai)動(dong)排(pai)種(zhong)(zhong)器(qi)、排(pai)肥器(qi)，按要(yao)求種(zhong)(zhong)肥量將(jiang)從種(zhong)(zhong)肥箱進入(ru)排(pai)種(zhong)(zhong)器(qi)和(he)排(pai)肥器(qi)的種(zhong)(zhong)子和(he)肥料排(pai)到由開(kai)溝(gou)器(qi)開(kai)好的種(zhong)(zhong)溝(gou)和(he)肥溝(gou)里，隨后覆土器(qi)覆土，鎮壓(ya)器(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(zhong)(zhong)機一般由種(zhong)(zhong)子箱、排(pai)(pai)種(zhong)(zhong)器、輸種(zhong)(zhong)管、開溝(gou)器、覆(fu)(fu)土(tu)器、行走輪、轉動機構等組成(cheng)。工作(zuo)時(shi)，開溝(gou)器在地(di)上開出種(zhong)(zhong)溝(gou)，種(zhong)(zhong)子箱內的(de)種(zhong)(zhong)子由排(pai)(pai)種(zhong)(zhong)器排(pai)(pai)出，經(jing)輸種(zhong)(zhong)管落(luo)入種(zhong)(zhong)溝(gou)，再由覆(fu)(fu)土(tu)器覆(fu)(fu)土(tu)完成(cheng)播種(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(wai)觀(guan)整(zheng)潔完好，有可(ke)靠的防(fang)護裝置(zhi)，記(ji)得(de)索要(yao)發票。

播種機怎么用

播(bo)(bo)(bo)種(zhong)(zhong)機在播(bo)(bo)(bo)種(zhong)(zhong)時(shi)，應(ying)按照種(zhong)(zhong)子的(de)(de)特點，對其進行播(bo)(bo)(bo)種(zhong)(zhong)。如播(bo)(bo)(bo)種(zhong)(zhong)的(de)(de)行距應(ying)該控(kong)制(zhi)在20厘米(mi)左右，不能過(guo)寬也(ye)不能過(guo)窄。播(bo)(bo)(bo)種(zhong)(zhong)深度應(ying)控(kong)制(zhi)在1.5—3.0厘米(mi)，但是也(ye)要(yao)(yao)考(kao)慮到(dao)特殊情況，不同(tong)的(de)(de)土(tu)壤(rang)播(bo)(bo)(bo)種(zhong)(zhong)的(de)(de)深度也(ye)不同(tong)，土(tu)壤(rang)偏旱，播(bo)(bo)(bo)深就要(yao)(yao)略深一(yi)點，這(zhe)樣可以防止(zhi)種(zhong)(zhong)子播(bo)(bo)(bo)淺，土(tu)壤(rang)過(guo)干而不能生長(chang)。因此(ci)，農機手(shou)在播(bo)(bo)(bo)種(zhong)(zhong)時(shi)，一(yi)定要(yao)(yao)充分考(kao)慮種(zhong)(zhong)子、土(tu)壤(rang)等情況，確(que)保種(zhong)(zhong)子的(de)(de)健康(kang)成(cheng)長(chang)。
