播種機有哪些種類

播(bo)(bo)種(zhong)機(ji)(ji)(ji)按種(zhong)子播(bo)(bo)到(dao)種(zhong)床的形(xing)狀可分(fen)(fen)為(wei)撒播(bo)(bo)機(ji)(ji)(ji)、條播(bo)(bo)機(ji)(ji)(ji)、穴播(bo)(bo)機(ji)(ji)(ji)；按動(dong)力(li)可分(fen)(fen)為(wei)人力(li)播(bo)(bo)種(zhong)機(ji)(ji)(ji)、畜(chu)力(li)播(bo)(bo)種(zhong)機(ji)(ji)(ji)和(he)機(ji)(ji)(ji)械播(bo)(bo)種(zhong)機(ji)(ji)(ji)；按排(pai)種(zhong)器取排(pai)種(zhong)原理可分(fen)(fen)為(wei)氣動(dong)式和(he)機(ji)(ji)(ji)械式；按聯合作業形(xing)式可分(fen)(fen)為(wei)旋耕(geng)播(bo)(bo)種(zhong)機(ji)(ji)(ji)、覆膜播(bo)(bo)種(zhong)機(ji)(ji)(ji)、免耕(geng)播(bo)(bo)種(zhong)機(ji)(ji)(ji)。

播種機械工作原理

播種(zhong)(zhong)機(ji)通過傳動(dong)系統帶動(dong)排種(zhong)(zhong)器(qi)、排肥(fei)器(qi)，按要求種(zhong)(zhong)肥(fei)量將(jiang)從(cong)種(zhong)(zhong)肥(fei)箱進入排種(zhong)(zhong)器(qi)和排肥(fei)器(qi)的種(zhong)(zhong)子和肥(fei)料排到由開溝(gou)器(qi)開好的種(zhong)(zhong)溝(gou)和肥(fei)溝(gou)里(li)，隨后覆土器(qi)覆土，鎮壓器(qi)壓實種(zhong)(zhong)床，完成播種(zhong)(zhong)作業(ye)。

播種機械的構造和工作過程

播種(zhong)(zhong)(zhong)(zhong)(zhong)機一般由(you)(you)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)箱(xiang)、排種(zhong)(zhong)(zhong)(zhong)(zhong)器、輸(shu)(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)管、開溝(gou)器、覆(fu)(fu)土(tu)器、行(xing)走輪、轉(zhuan)動機構等組成(cheng)。工(gong)作時，開溝(gou)器在地上(shang)開出種(zhong)(zhong)(zhong)(zhong)(zhong)溝(gou)，種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)箱(xiang)內的(de)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)(zi)由(you)(you)排種(zhong)(zhong)(zhong)(zhong)(zhong)器排出，經輸(shu)(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)管落入種(zhong)(zhong)(zhong)(zhong)(zhong)溝(gou)，再由(you)(you)覆(fu)(fu)土(tu)器覆(fu)(fu)土(tu)完(wan)成(cheng)播種(zhong)(zhong)(zhong)(zhong)(zhong)作業。

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(guan)整(zheng)潔完好，有可靠(kao)的防護(hu)裝(zhuang)置，記得索要發票。

播種機怎么用

播(bo)(bo)(bo)(bo)種(zhong)(zhong)機在播(bo)(bo)(bo)(bo)種(zhong)(zhong)時(shi)，應按照種(zhong)(zhong)子(zi)的(de)特(te)點(dian)(dian)，對(dui)其(qi)進行(xing)播(bo)(bo)(bo)(bo)種(zhong)(zhong)。如播(bo)(bo)(bo)(bo)種(zhong)(zhong)的(de)行(xing)距應該控制(zhi)在20厘米左右(you)，不(bu)能過寬也不(bu)能過窄。播(bo)(bo)(bo)(bo)種(zhong)(zhong)深度應控制(zhi)在1.5—3.0厘米，但是也要(yao)(yao)考(kao)慮(lv)到特(te)殊情況(kuang)，不(bu)同的(de)土(tu)壤播(bo)(bo)(bo)(bo)種(zhong)(zhong)的(de)深度也不(bu)同，土(tu)壤偏旱，播(bo)(bo)(bo)(bo)深就要(yao)(yao)略深一點(dian)(dian)，這樣可以防止種(zhong)(zhong)子(zi)播(bo)(bo)(bo)(bo)淺，土(tu)壤過干而(er)不(bu)能生長。因此，農(nong)機手在播(bo)(bo)(bo)(bo)種(zhong)(zhong)時(shi)，一定(ding)要(yao)(yao)充分考(kao)慮(lv)種(zhong)(zhong)子(zi)、土(tu)壤等情況(kuang)，確保(bao)種(zhong)(zhong)子(zi)的(de)健康成長。
