為了提高大(da)蒜(suan)的(de)(de)(de)(de)播種效率，減少蒜(suan)苗(miao)的(de)(de)(de)(de)浪(lang)費，在(zai)最近的(de)(de)(de)(de)一段(duan)時(shi)間，我根據大(da)蒜(suan)的(de)(de)(de)(de)種植特點(dian)做了一錐(zhui)形(xing)螺旋管(guan)的(de)(de)(de)(de)模(mo)型，錐(zhui)形(xing)管(guan)內徑50mm,錐(zhui)形(xing)直徑900mm,圈(quan)高1500mm,經挑選(xuan)后的(de)(de)(de)(de)蒜(suan)瓣(ban)自由下落(luo)在(zai)錐(zhui)形(xing)螺旋管(guan)的(de)(de)(de)(de)作用下入土的(de)(de)(de)(de)蒜(suan)瓣(ban)根朝下牙朝上(shang)的(de)(de)(de)(de)大(da)概有(you)8成(cheng)數量，基(ji)本上(shang)是成(cheng)功的(de)(de)(de)(de)。

大蒜播種機的工作原理

大(da)蒜(suan)播種(zhong)(zhong)(zhong)機采用(yong)(yong)點播技術，按(an)行(xing)距(ju)(ju)和窩距(ju)(ju)先用(yong)(yong)壓(ya)穴(xue)(xue)錐(zhui)(zhui)(zhui)(zhui)壓(ya)穴(xue)(xue)以型成(cheng)一定大(da)小孔(kong)洞(dong)形(xing)錐(zhui)(zhui)(zhui)(zhui)穴(xue)(xue)，經挑選后的(de)蒜(suan)瓣(ban)經分種(zhong)(zhong)(zhong)器自由下(xia)(xia)落在(zai)錐(zhui)(zhui)(zhui)(zhui)形(xing)螺(luo)旋(xuan)導(dao)(dao)種(zhong)(zhong)(zhong)管(guan)的(de)作(zuo)(zuo)用(yong)(yong)下(xia)(xia)入(ru)土的(de)蒜(suan)瓣(ban)根(gen)朝下(xia)(xia)牙朝上剛好落入(ru)錐(zhui)(zhui)(zhui)(zhui)穴(xue)(xue)孔(kong)洞(dong)中(zhong)而不(bu)致(zhi)于傾斜(xie)，播種(zhong)(zhong)(zhong)機在(zai)行(xing)進中(zhong)壓(ya)穴(xue)(xue)錐(zhui)(zhui)(zhui)(zhui)與分種(zhong)(zhong)(zhong)器必(bi)須要同步，蒜(suan)瓣(ban)自由下(xia)(xia)落經錐(zhui)(zhui)(zhui)(zhui)形(xing)螺(luo)旋(xuan)導(dao)(dao)種(zhong)(zhong)(zhong)管(guan)的(de)滯后時間要使(shi)蒜(suan)瓣(ban)剛好能(neng)進入(ru)孔(kong)洞(dong)中(zhong)。錐(zhui)(zhui)(zhui)(zhui)形(xing)螺(luo)旋(xuan)管(guan)導(dao)(dao)種(zhong)(zhong)(zhong)管(guan)內(nei)孔(kong)壁光滑內(nei)孔(kong)的(de)直(zhi)(zhi)徑要比蒜(suan)瓣(ban)最(zui)大(da)尺(chi)(chi)寸大(da)10mm才能(neng)使(shi)蒜(suan)瓣(ban)自由下(xia)(xia)落在(zai)錐(zhui)(zhui)(zhui)(zhui)形(xing)螺(luo)旋(xuan)導(dao)(dao)種(zhong)(zhong)(zhong)管(guan)的(de)作(zuo)(zuo)用(yong)(yong)下(xia)(xia)入(ru)土的(de)蒜(suan)瓣(ban)根(gen)朝下(xia)(xia)牙朝上和不(bu)致(zhi)于賭管(guan)。（錐(zhui)(zhui)(zhui)(zhui)形(xing)螺(luo)旋(xuan)導(dao)(dao)種(zhong)(zhong)(zhong)管(guan)的(de)模型尺(chi)(chi)寸:錐(zhui)(zhui)(zhui)(zhui)形(xing)導(dao)(dao)種(zhong)(zhong)(zhong)管(guan)內(nei)徑50mm,錐(zhui)(zhui)(zhui)(zhui)形(xing)直(zhi)(zhi)徑900mm,圈(quan)高1500mm）

大蒜(suan)播(bo)(bo)種(zhong)(zhong)機采用點(dian)播(bo)(bo)和錐形螺旋(xuan)導(dao)種(zhong)(zhong)管(guan)技術(shu)，錐穴孔洞大小可以(yi)保證蒜(suan)瓣(ban)(ban)入(ru)(ru)土鱗芽朝(chao)上(shang)不致(zhi)于傾斜，錐形螺旋(xuan)導(dao)種(zhong)(zhong)管(guan)的(de)結構尺寸大小決定了蒜(suan)瓣(ban)(ban)入(ru)(ru)土的(de)鱗芽朝(chao)上(shang)率(lv)(lv)。蒜(suan)瓣(ban)(ban)的(de)結構尺寸及重心大概在大頭根部即總(zong)長(chang)三(san)分之一的(de)地方(fang)，蒜(suan)瓣(ban)(ban)在錐形螺旋(xuan)導(dao)種(zhong)(zhong)管(guan)內的(de)下(xia)落速度和自旋(xuan)速度越快蒜(suan)瓣(ban)(ban)入(ru)(ru)土的(de)鱗芽朝(chao)上(shang)率(lv)(lv)就(jiu)越高。

大蒜播種機經濟意義

我(wo)國大(da)(da)蒜種(zhong)植還(huan)是以手(shou)工栽種(zhong)為(wei)主，勞(lao)動強(qiang)度(du)大(da)(da)，生產效率低，每(mei)個成(cheng)年勞(lao)動力每(mei)天僅能(neng)播種(zhong)133.3m2，每(mei)播種(zhong)1畝的大(da)(da)蒜需(xu)要付費(fei)150元，成(cheng)本(ben)很(hen)高，而且在農忙季節經常出現無雇(gu)工可用的現象。

近年來，大(da)蒜(suan)價(jia)格持續走(zou)高，激發了農民種(zhong)植(zhi)的(de)(de)積(ji)極性，大(da)蒜(suan)種(zhong)植(zhi)面積(ji)不斷(duan)增加，完全(quan)的(de)(de)手工勞動顯然無法滿足(zu)規模化(hua)的(de)(de)種(zhong)植(zhi)需求，同(tong)時也(ye)提高了種(zhong)植(zhi)成本，也(ye)將(jiang)進一步導致大(da)蒜(suan)價(jia)格繼續上揚。據相(xiang)關部門統計，我(wo)國農業(ye)機(ji)械銷售量每年至少以25%的(de)(de)速度遞增，這也(ye)為項目(mu)產品的(de)(de)市場銷售提供了機(ji)遇(yu)。
