201210463 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種種植機，尤其是關於一種將種子球 種植於田地的種植機之技術。 【先前技術】 習知以來，蒜頭等之種子球，係以種子球之芽成爲上 方、種子球之根成爲下方的方式來種植。不適當的種植， 將關係著因發芽不良等而引起收穫量之減少及等級之降低 等。因而，爲了收穫高品質的作物，就不得不進行種子球 之親手種植。 但是，在以種子球爲商品作物而進行栽培時，因農作 面積之擴大等，在手工方面對作業者帶來很大的負擔。因 此，有提出將種子球種植於田地的多種種植機。 例如，專利文獻1所示的種植機，係具備：保持具（ holder)，其係在種植前暫時容納作物（種子球）；及上 下機構，其係使保持具在容納位置和種植位置之間循環； 及推出桿部，其係將容納於保持具的作物推出並進行種植 :以及上下動機構，其係使推出桿部朝上下移動。該種植 機，係將推出桿部從移動至種植位置的保持具之上端部插 入’且藉由該推出桿部將容納於保持具的作物往下方推出 ，藉此可將作物種植於田地。 (專利文獻1)日本特開2009-213359號公報 -5- 201210463 【發明內容】 (發明所欲解決之問題） 但是，專利文獻1所示的 部，並未考慮種子球之形狀或 子球對推出桿部的穩定性差， 球無法以適當的姿態種植於田 因此本發明之目的在於提 姿態種植於田地的種植機。 (解決問題之手段） 在申.請專利範圍第1項中 部、以及進行種子球之種植的 —邊朝行走方向以每一預定間 機，前述種植部，係具備：保 球；以及推出手段，其係將由 子球往田地一邊推出一邊種植 備：筒狀的導引構件，其係使 種子球往田地移動；以及種植 件並將藉由該導引構件而移動 邊種植，其中前述導引構件， 時可保持該種子球的保持體， 向前述保持手段開口的筒狀， 角形。 種植機中之保持具及推出桿 種植姿態而構成。因而，種 而有被推出桿部推出的種子 地的情況。 供一種可將種子球以適當的 ，一種種植機，係具備行走 種植部，且一邊行走於田地 隔進行種子球之種植的種植 持手段，其係用以保持種子 前述保持手段所保持中的種 ，其中前述推出手段，係具 由前述保持手段所保持中的 桿，其係內裝於前述導引構 的種子球往田地一邊推出一 係具備用以在使種子球移動 而前述保持體，係呈一側朝 並將其內周剖面形狀形成多 在申請專利範圍第2項中，前述保持體係由軟質材料 201210463 所構成。 在申請專利範圍第3項中，前述保持手段，係將：保 持板’其係於中央形成有插入孔且從該插入孔朝與前述保 持體一致的多角形之頂點方向形成有裂縫；以及開孔板， 其係於中央形成有比前述種子球還更大的開孔部，以該插 入孔和該開孔部之中心爲一致的方式交互地重合複數個而 形成，且配置於上下方向中央的前述保持板之插入孔，係 構成比配置於上下兩側的保持板之插入孔還更大。 在申請專利範圍第4項中，在配置於前述上下兩側的 保持板之間所配置的中間層之保持板之插入孔，係形成越 靠近下側則開孔面積就越大。 (發明效果） 作爲本發明的效果，係可達成如下所示的效果。 在申請專利範圍第1項中，當將種子球種植於田地時 ，保持體，係以複數處接觸到種子球之外周面，並以適當 的姿態來保持該種子球。因而，藉由種植桿將由保持體所 保持的種子球推出，藉此就可以保持原來狀態的適當姿態 種植於田地。 在申請專利範圍第2項中，當保持體保持種子球時， 保持體會配合種子球之外形而變形，藉此可增大保持體之 與種子球的接觸面積，且容易以適合保持體的姿態來保持 種子球。因而，可將種子球以適當的姿態種植於田地。而 且，因保持體柔軟地接觸種子球之外周面故而不會傷到種 201210463 子球。 在申請專利範圍第3項中，由於保持體之頂點和保持 板之裂縫爲一致，所以在保持適當姿態的狀態下可保持種 子球而適當地進行種植作業。在此，一般而言種子球以俯 視觀察係呈大致多角形。換句話說，種子球之頂點，係可 配合保持板之裂縫而保持，且當承繼於推出手段之導引構 件而推出時，該保持的狀態並不會有變化而可由保持體所 保持。因而，推出時種子球之芽的方向不會發生偏移或落 下，而可確實地保持並進行種植。 又，上下方向中間層的保持板之插入孔係形成比上下 兩側的插入孔還更大。因而，比起形成相同大小的插入孔 還可減輕因種子球和保持板所引起的過大摩擦力，並且可 藉由保持板之插入孔的內面而適度地保持種子球》因而， 當作業者將種子球插入於保持手段時不會產生較大的摩擦 ，而可容易插入且不會傷及種子球。更且，可以適合保持 手段的姿態來保持種子球，且可利用推出手段將種子球以 適當的姿態種植於田地。 在申請專利範圍第4項中，中間層的保持板之插入孔 ，係形成下側（排出側）的開孔面積比上側（插入側）的 開孔面積還更大。換句話說，形成內部空間隨著靠近下側 而變大。因此，作業者在插入種子球時，靠近最下側的的 保持板之前面會在取決於保持板的新阻力變無、或被減輕 之後，因最下面的保持板而再次感受到新的阻力。因而， 作業者較容易掌握保持手段中的種子球之插入位置。 -8- 201210463 然後，由於種子球主要可一邊藉由配置於上下兩側的 保持板以適度之力來保持一邊容易以適當的姿態插入於保 持手段，所以可藉由推出手段以適當的姿態種植於田地。 【實施方式】 其次，說明發明的實施形態。 另外，雖然是假想在壟上被覆有覆蓋紙（mulch sheet )之狀態下的種植而加以說明’但是並非特別限定於此’ 亦可爲種植於並未被覆有覆蓋紙之大致平坦的田地之情況 〇 以下，係參照第1圖至第5圖，就本發明之一實施形態 的種植機1之整體構成加以說明。 在說明中，係將圖中所示的箭頭A之方向當作種植機1 之前方向，並規定前後左右方向。 種植機1，係爲了在被覆有覆蓋紙10之壟上，種植種 子球G而使用的種植機。種植機1，主要是具備機體框架12 、驅動部13、行走部I4、運轉操作部15、動力傳遞機構、

係配置有動力傳遞機構、或使種植部17升降以保持種植面 (田地）和種植部17之距離於適當高度的升降連桿（link )機構11等。升降連桿機構11，係藉由配置於前後方向的 保護外殻155來覆蓋其上方。 前述種植框架18，係種植部I7之一部分且爲形成種植 部17之骨架的構造體。種植框架18，係從機體框架12之後 部中介升降連桿機構11，配設於機體框架12之前方。種植 框架18，主要是藉由主種植框架181、側部種植框架182及 橫向種植框架183而構成。 如第1圖至第5圖所示，主種植框架181，係藉由將管 件等之棒材彎曲成在側面觀察中後下部呈開放的多角形而 形成，且隔開比左右的機體寬度還稍短的間隔，以成爲左 右一對的方式配置。當詳細說明時，主種植框架181，係 以其一端位於種植部17之後部之上下中途部的方式形成。 以從主種植框架181之後端朝向前上方，成爲前高後低的 方式形成有後傾斜部1 8a。更在種植部1 7之上部，形成有 水平部18b。從水平部18b之前部來看，以前上部成爲前低 後高的方式形成有前上傾斜部1 8c。以從前上傾斜部1 8c之 下部朝向種植部17之中央成爲前高後低的方式形成有前下 傾斜部18d»然後，主種植框架181之另一端，係以位於種 植部17之前下部的方式形成。 在左右的主種植框架181、181，係於上下方向及前後 方向配置有側部種植框架182。在左右的主種植框架181、 1 8 1間，係橫向設置有橫向種植框架1 8 3、1 8 3。 -10- 201210463 藉由如此構成，種植框架1 8係於內部形成有空間，且 能夠在該空間內配置後述的各種種植裝置。更且主種植框 架181、181，係可藉由蓋件171來覆蓋其左右外側。在主 種植框架1 8 1、1 8 1之兩內側，係以環狀體蓋件1 72朝內方 突出的方式而配置。 前述驅動部13，係由作爲動力源的引擎131及未圖示 的發電機等所構成，且爲將動力傳遞至行走部14和種植部 17以驅動各部者。驅動部13，係搭載於機體框架12之後部 上，且以與連結於機體框架12前部的種植部17取得前後方 向之重量平衡的方式配置。在驅動部13之上方，係配設有 置放收納有種子球G之籃子153等的載置部154。 行走部14，係由左右一對的履帶（crawler ) 140、140 等所構成，且來自驅動部13之動力是通過變速箱（mission case) 141而傳遞，藉此能夠使種植機1行走。 運轉操作部1 5，係配設於機體框架1 2之前後中央部， 可進行行走部1 4及種植部1 7之操縱。運轉操作部1 5，係由 可供作業者就座的座位1 5 1、1 5 1、以及配置有用以進行行 走部14及種植部17之操作的複數個操作槓桿（operating lever)等之操作塔（operating column) 152等所構成。 座位151，係位於引擎131前方且左右並置於機體框架 1 2上。座位1 5 1、1 5 1，係以就座的面成爲前低後高的方式 配設，俾於可容易供作業者將種子球插入於後述的種子球 保持具21 (參照第8圖）。具體而言，如第2圖所示，座位 151之座部（就座的面）之前下面係可藉由以左右方向爲 -11 - 201210463 軸心的樞支軸而支撐，而後下面係抵接於支撐棒151a之上 端。該支撐棒1 5 1 a係在其側面形成有螺紋槽，且相對於機 體框架12朝上下方向螺設。如此，藉由旋轉支撐棒151a， 就可調整支撐棒151a之上端的高度，且可調整座位151之 就座的面之傾斜。換句話說，可調節就座的作業者之前傾 姿勢，並配合作業者之體格或作業容易度而調整座位151 之座部面的傾斜角度。但是，亦可形成配置能夠變更卡合 高度的卡合構件或高度不同的止動件來取代支撐棒151a之 構成，只要是可變更後下面之高度的構成則非爲限定。 操作塔152，_然是配置在座位151之周圍近旁，但是 在本實施形態中係配置在機體右外側之座位1 5 1的右斜前 方。構成爲藉由操作塔1 5 2之操作槓桿等的操作就可進行 往行走部1 4之動力的斷開/接通或變速操作、以及往種植 部17之動力的斷開/接通操作》 操作塔152，係形成箱狀。在操作塔152之上面，配置 有作業離合器槓桿（clutch lever)、行走離合器槓桿、側 面離合器槓桿、種植高度自動調整開關、行走方向自動調 整開關。在操作塔1 52之後面，係配置有引擎停止開關、 種植升降開關、種植部驅動開關等。使種植機1之行走速 度變速的行走變速槓桿，在本實施形態中，係配置於右座 位1 5 1之下右側面。 第1圖及第2圖所示的種子球補給部1 9，係用以暫時貯 留對後述的保持開孔手段2進行補給的種子球。種子球補 給部1 9，主要是藉由補給箱1 9 1及輔助供給箱1 92而構成。 -12- 201210463 補給箱1 9 1，係供被插入於種植部1 7之保持開孔手段2 的種子球G在插入前可暫時容納的容器。 補給箱191，係形成大致槽溝狀（gutter-shaped)，且 爲比種植部17之左右寬度稍短、而上部呈開放且左右兩端 呈閉塞的容器。該補給箱1 9 1之左右兩側部係固設於主種 植框架1 8 1的後傾斜部1 8a之後內側、以及環狀體蓋件1 72 之後端。 輔助供給箱1 92，係用以對補給箱1 9 1內供給新的種子 球G者。輔助供給箱192、192，係在左右的蓋件171及環狀 體蓋件172之上面配置成爲左右一對。輔助供給箱192，主 要是藉由容納部193、誘導部194及分隔板195而構成。 容納部1 9 3，係上部呈開放之大致箱狀的容器，且爲 用以貯留種子球G者。容納部193，係夾介安裝構件（省略 圖示）而固設在蓋件171及環狀體蓋件172之上面。容納部 1 93之保持開孔手段2側，係以在左右方向成爲大致相同之 位置的方式配置。容納部1 93之機體外方側，係以比蓋件 171之外側面還更突出的方式配置。容納部193之後部，係 爲了沿著蓋件171、主種植框架181之後傾斜部18a及環狀 體蓋件172之上面而以往後下方突出至後傾斜部IS a之前後 中途部的方式配置。在該突出部分之後部的保持開孔手段 2側，係形成有開口部。 誘導部194，係大致呈隧道狀的構件，且爲用以將容 納部193內的種子球G朝補給箱192供給的通路。誘導部194 ，係固設在容納部1 93之後方的環狀體蓋件1 72及後傾斜部 -13- 201210463 18a之上面。誘導部194之一端（上端）’係連接於目II述谷 納部193之開口部。誘導部194之另一端（下端）’係配置 在補給箱191之左右兩端部的上方。誘導部194之另一端’ 係在補給箱1 9 1側形成有開口部。 分隔板195，係用以防止誘導部194之通路內的種子球 G之堵塞者。分隔板195，係藉由與誘導部194之左右寬度 大致相同的板狀之構件而構成。分隔板195 ’係在誘導部 194之上面，以誘導部194內之通路剖面隨著從種子球G的 供給方向之上游側朝下游側變大的方式配置。更且，分隔 板195，係以使其上端部朝誘導部194之上面方向彎曲並進 而安裝於上面的方式形成。 藉由如此構成，比誘導部194之上游側還更靠近下游 側的通路剖面就會變大，而容易將種子球G供給至補給箱 191。 在前述構成中，作業者係用手取出補給箱1 9 1內的種 子球G，並插入於保持開孔手段2。另外，由於補給箱191 係形成左右連通的構成，所以在位於左右一側的作業者之 前方的種子球G變無時，就容易使左右另一側的補給箱191 內之種子球G朝一側移動，並進行種子球G之補充。 更且，當補給箱191之端部的種子球G減少時，可從輔 助供給箱192之容納部193經由誘導部194，並藉由種子球G 之本身重量朝補給箱191內供給種子球G。因而，作業者， 可減少因補給箱191內之種子球G的不足而造成種植作業之 停止，且可效率佳地進行種植作業。 -14 - 201210463 又，若補給箱1 9 1及輔助供給箱1 92內之種子球G變無 的話，則種子球G就能夠從座位151之後方的籃子153補給 至補給箱1 9 1及輔助供給箱1 92。 又，亦可設置第二輔助供給箱3 92作爲另一實施形態 ，以取代本實施形態的輔助供給箱1 92。如第3圖及第4圖 所示，第二輔助供給箱392，主要是藉由容納部393、誘導 部394及分隔部3 95而構成。容納部393及誘導部394的基本 構造係與輔助供給箱192之容納部193相同。容納部3 93， 係可供用以支撐後述的分隔部3 95之螺栓3 93 a、3 93 a以在 上下方向隔開預定間隔並在下後斜面往後下方突出的方式 固設。誘導部394，係在與容納部393之安裝部分近旁的機 體外側面形成有插入孔394a » 分隔部3 95，係形成擋門構造，具體而言，係藉由將 板狀之構件以具有分隔板395a和相對於該分隔板3 95 a成爲 直角的置手板39 5b之方式彎曲而形成。在分隔板395a，係 隔開與前述螺栓393a同等的上下間隔而形成有將左右方向 當作長邊的長孔3 95c、3 95c。分隔板395a，係可將其一端 (機體內方端）插入於誘導部394之插入孔394a。在長孔 395c、3 95c，係能夠以藉由與形成於容納部393之螺栓 3 93 a、393 a嵌合且利用螺帽3 93b、3 93b而緊固並順沿容納 部3 93之下後斜面的方式固定分隔板3 9 5 a。 因而，作業者，係在鬆開螺帽393b、3 93b之狀態下， 一邊夾持置手板395b —邊使螺栓393a、393a滑動於長孔 3 95 c、3 95 c，而使分隔板3 9 5a朝左右方向移動，藉此調整 -15- 201210463 誘導部394之上部的內部通路剖面。藉由作業者緊固螺帽 393b、393b，就可在所期望位置，將分隔板395a固定在容 納部3 93之後側面。 藉由如此構成，比誘導部3 94之上游側還更靠近下游 側的通路剖面就會變大，而容易將種子球G供給至補給箱 191。 如第1圖、第2圖及第5圖所示，動力傳遞機構，係將 引擎131之驅動力傳遞至行走部14及種植部17。動力傳遞 機構，在本實施形態中雖然是由皮帶和滑輪、鏈條和鏈輪 、傳動軸、齒輪、以及變速箱141等而構成，但是亦可使 用其他的構成零件。 來自引擎131的驅動力，係可藉由屬於動力傳遞機構 的滑輪、皮帶、傳動軸，而傳遞至變速箱141。傳遞至變 速箱1 4 1的動力，係在變速箱1 4 1內變速後，經由鏈條及鏈 輪而傳遞至行走輪268、268，藉此行走部14之履帶140、 140就可驅動而行走。 其次，使用第1圖、以及第5圖至第7圖說明往種植部 17之驅動力的傳遞。 來自引擎131的驅動力，係通過引擎131之前方之未圖 示的傳動軸、齒輪、滑輪及皮帶等的動力傳遞機構而藉此 一邊變速及改變動力傳遞方向，一邊傳遞至種植輸入軸 365 (參照第5圖）。 種植輸入軸3 65，係在運轉操作部1 5之前部，轉動自 如地支撐於種植部1 7之位於左側的種植框架1 8後部。 -16- 201210463 在種植輸入軸365之左右中途部’係固設有往推出手 段4 (參照第12圖）傳遞動力的第一種植傳遞機構16a之驅 動鏈輪40。 另一方面，在種植輸入軸365之左端’係固設有往環 狀體3傳遞動力的第二種植傳遞機構16b之驅動鏈輪30。 換句話說，種植輸入軸365之動力，係可同時傳遞至 配置於其前方的第一種植傳遞機構16a及第二種植傳遞機 構 1 6b。 如第5圖及第6圖所示，第一種植傳遞機構16a’主要 是藉由驅動鏈輪40、隨動鏈輪41、張力鏈輪42、推出驅動 鏈輪43、傳動鏈條44及推出驅動軸45而構成。 在種植輸入軸365之左右中途部，係固設有驅動鏈輪 40。在種植輸入軸365之前上方（種植部17之上部），係 配置有比種植部17之左右寬度還稍短的推出驅動軸45。推 出驅動軸45，係旋轉自如地支撐於種植框架18之左右。在 推出驅動軸45之左端，係固設有推出驅動鏈輪43。在驅動 鏈輪40之前上方，係配置有隨動鏈輪41，而在推出驅動鏈 輪43之後下方，係配置有張力鏈輪42。 在驅動鏈輪40、隨動鏈輪41、張力鏈輪42及推出驅動 鏈輪43，係捲繞有環狀的傳動鏈條44。但是，隨動鏈輪41 係卡合於傳動鏈條44之外周，而張力鏈輪42係卡合於傳動 鏈條44之內周。因而，傳動鏈條44，係可保持適度的張力 ，且可防止在推出驅動鏈輪43和驅動鏈輪40間下垂。 因而，從種植輸入軸365經由驅動鏈輪40、傳動鏈條 -17- 201210463 44及推出驅動鏈輪43，可將動力傳至推出驅動軸45。在推 出驅動鏈輪43和推出驅動軸45之間，係配置有後述的離合 器，且可藉由離合器之作用而限制動力的傳遞。然後，傳 至推出驅動軸45的動力，係通過曲柄驅動部5而使推出手 段4 (參照第1 3圖）動作。 第二種植傳遞機構16b，主要是藉由驅動鏈輪30、旋 轉軸31、隨動鏈輪31a、隨動鏈輪31b、張力鏈輪34、環狀 體驅動鏈輪32、環狀體驅動軸33、傳動鏈條30a、32 a而構 成。 在前述種植輸入軸365之左端，係固設有驅動鏈輪30 。在種植輸入軸365之前下方（種植部17之後下部），係 配置有旋轉軸31。旋轉軸31，係可將其兩端旋轉自如地支 撐於左側的種植框架18。在旋轉軸31之右端上，係固設有 隨動鏈輪31a，而在旋轉軸31之左端上，係固設有隨動鏈 輪 3 lb。 在驅動鏈輪30及隨動鏈輪31a，係捲繞有環狀的傳動 鏈條30a。在隨動鏈輪31a之下方（種植位置17b上方）， 係配置有環狀體驅動軸33。環狀體驅動軸33，係轉動自如 地支撐於左右的種植框架1 8。 在環狀體驅動軸33之左端，係固設有環狀體驅動鏈輪 3 2。在環狀體驅動鏈輪3 2之右側的環狀體驅動軸3 3上，係 轉動自如地支撐張力臂34a之下端。在張力臂34a之上端’ 係以朝左方突出的方式固設有轉動軸34b。在轉動軸34b之 右端，係轉動自如地支撐張力鏈輪34»在隨動鏈輪31b、 -18- 201210463 環狀體驅動鏈輪32及張力鏈輪34，係捲繞有環狀的傳動鍵 條32a。張力臂34 a係成爲可藉由未圖示的彈簧而彈壓’並 能夠對傳動鏈條32a賦予張力的構成。 因而，種植輸入軸365之動力，係可通過驅動鏈輪30 、傳動鏈條30 a及隨動鏈輪31a，而傳遞至旋轉軸31°然後 ，旋轉軸31之動力，係可通過隨動鏈輪31b、傳動鏈條3 2a 、張力鏈輪34、環狀體驅動鏈輪32，而傳遞至環狀體驅動 軸33。 更且，如第5圖至第7圖所示，在環狀體驅動軸33上’ 係於主種植框架181之兩內側，固設有內環狀體驅動鏈輪 3 5、3 5。以在側面觀察中形成有預定空間的方式，配置有 左右的環狀體隨動鏈輪36、37、38、39。在左右的環狀體 隨動鏈輪36、37、38、39，係捲繞有由環狀之鏈條等所構 成的環狀體3。由於環狀體3係配置成左右對稱，所以以下 主要是以左側進行說明。 又，種植位置1 7b，係將種子球G往田地種植的位置， 且被配置於種植部1 7之最下部。 下環狀體隨動鏈輪39及其後方的內環狀體驅動鏈輪35 之下端，以側面觀察是並排配置於前後水平方向。更且， 在種植部17之下部，配置有導引構件174，俾於隨著捲繞 於前述各環狀體隨動鏈輪36' 37' 38' 39的環狀體3之旋 轉，可使保持開孔手段2往後方大致水平地移動。該導引 構件1 74係形成可供後述的保持開孔手段2之輥子29被導引 的構成。 -19- 201210463 如此，可在補給位置17a和種植位置17b之間捲繞環狀 體3，而保持開孔手段2，係形成：除了在補給位置1 7a以 外，還可在插入方向轉向鉛垂方向的狀態下被旋轉驅動之 構成。因而，形成：內環狀體驅動鏈輪35是以在種植位置 17b之後部側拉伸並驅動的方式配置，並旋轉驅動環狀體3 的構成。換句話說，種植位置17b之環狀體3係成爲在種植 作業時始終被拉伸的狀態而不會鬆弛，並能夠行走及與曲 柄驅動部5同步而正確地進行種植。然後，保持開孔手段2 之種子球G並不會大幅度地擺動，且也不會被抖落，而可 確實地從補給位置17a搬運至種植位置17b。 環狀體3，係如前述般地由環狀之鏈條等所構成，且 以在種植框架1 8之內部以側面觀察成爲多角形（五角形） 的方式張設。詳言之，環狀體3，係捲繞於作爲旋轉支撐 部的內環狀體驅動鏈輪35、各環狀體隨動鏈輪36、37、38 、39，該內環狀體驅動鏈輪35係左右一對在種植框架18之 左右兩內側以成爲側面觀察呈多角形狀之頂部位置的方式 分別設置。在左右的環狀體3之間，係有保持開孔手段2於 環狀體3之旋轉方向以每一預定間隔橫架於左右方向。 然後，如第2圖及第5圖至第7圖所示，補給位置17a係 傾斜成前高後低之預定角度而配置，俾於在運轉操作部15 之前方可輕易地將種子球G往保持開孔手段2補給（插入） 。亦即，在種植部17之前後中央部的最上部配置有上環狀 體隨動鏈輪37。上環狀體隨動鏈輪37之高度，係在種植作 業時，爲了可確保前方視野而形成比作業者之眼睛高度還 -20- 201210463 更低、比膝蓋還更高，且形成肩膀之高度程度。 配設在上環狀體隨動鏈輪37之後下方的後環狀體隨動 鏈輪36之高度，係比踏板12a還更高而比作業者之胸部還 更低，且形成座位151之座面的高度程度。如此，張設在 上環狀體隨動鏈輪37與內環狀體驅動鏈輪35之間的環狀體 3傾斜成前高後低而配設，並配置了補給位置17a。 前述補給位置17a，係在座位151之前方，配置在就座 於座位1 5 1的作業者之手可到達的範圍。補給位置1 7a，詳 言之係在上環狀體隨動鏈輪3 7和後環狀體隨動鏈輪36之間 ，以環狀體3傾斜預定角度成爲前高後低的方式配置。^ —邊保持該角度一邊使保持開孔手段2往斜前上方移動的 方式，使內環狀體驅動鏈輪35配設在種植框架18。亦即， 在上環狀體隨動鏈輪3 7和後環狀體隨動鏈輪36之間的環狀 體3之下方，係配置有將前後方向當作長邊方向的板狀之 導引構件173。導引構件173，係以與環狀體3成爲平行的 方式固設在種植框架18。導引構件173，係可供設置於保 持開孔手段2之兩側的後述之輥子29轉動於其上面而導引 ’且以種子球保持具2 1之種子球插入面一邊朝向作業者側 —邊往前上方移動的方式構成。在該補給位置1 7 a，係平 行地配置有複數排（本實施形態中爲三排）的保持開孔手 段2，且在種子球G之補給時間上有多少的餘裕度，即便錯 過了補給時機也可以輕易地修正。 如此，作業者可在保持就座於座位1 5 1之狀態下，以 將種子球G供給至後述的保持開孔手段2之姿態進行作業， -21 - 201210463 且可減輕疲勞，並提高作業效率。 前述環狀體驅動鏈輪32，係可藉由變更其直徑（齒數 )，而變更種子球G之種植間隔（株樹）P。換句話說，若 環狀體驅動鏈輪32之直徑變大（齒數變多），種植間隔P 就會變長，若其直徑變小（齒數變少）則種植間隔P就會 變短。 作業者，係能夠藉由變更環狀體驅動鏈輪3 2，而選擇 所期望的種植間隔P。但是，亦可形成：在環狀體驅動鏈 輪32，配置有段或無段的變速機構之構成。另外，在該情 況下，有段或無段的變速機構較佳是可以槓桿等的操作輕 易地進行變速操作。 其次，就藉由前述動力傳遞機構而驅動的種植部17加 以說明》 種植部17，係爲了將種子球G種植於田地，而配置於 種植機1之前部。本實施形態中的種植部17，主要是藉由 種植框架18、配置於種植框架18之內部的保持開孔手段2 以及推出手段4等的各種植裝置等而構成》 其次，使用圖式就配置於種植框架18內的種植部17之 各種植裝置之構成加以說明。 種植部17之各種植裝置，主要是藉由配置於前述環狀 體3上的保持開孔手段2、推出手段4等而構成。 如第1圖及第7圖至第12圖所示，保持開孔手段2，係 —邊保持種子球G，一邊在種子球G到達種植位置17b時’ 在覆蓋紙1 〇上開出孔的手段。在本實施形態中，保持手段 -22- 201210463 ，係當作具有可在覆蓋紙1 0形成開孔部的開孔手段之保持 開孔手段2。但是，若另外具有開孔手段或事先在覆蓋紙 設置開口部的話，則只要是具有可一邊保持種子球G—邊 搬運至種植位置1 7b的功能之保持手段即可。保持開孔手 段2，主要是藉由盒體23、複數個種子球保持具21及開孔 體26而構成。 盒體23，係將左右方向當作長邊之能夠上下分割的箱 狀之構造體。在盒體23之上面及下面，係以在左右方向隔 開預定間隔並成爲上下一對的方式形成有複數個（由於在 本實施形態中爲四條所以上下四處共計有八處）上下開口 部23a，俾於可進行種子球G之插入及排出。 在盒體23之上開口部23 a的周圍下側，係分別固設有 具有種子球G之插入孔且用以保持種子球G的種子球保持 具21。又，開孔體26係配置於前述種子球保持具21之下方 的盒體23上。 前述種子球保持具21，係具有複數個矩形狀的保持板 (第一保持板211、第二保持板212、第三保持板213)和 複數個矩形狀的開孔板214。種子球保持具21，係使中心 及方向一致並逐一使保持板和開孔板214上下交互地貼合 而形成。詳言之，種子球保持具21，係自上起依第一保持 板2 1 1、開孔板2 1 4、第二保持板2 1 2 '開孔板2 1 4、第三保 持板2 1 3、開孔板2 1 4及第一保持板2 1 1之順序重合。 開孔板2 1 4，係由胺基甲酸乙酯等之彈性體板所構成 ，且於其大致中央形成有直徑比種子球G還更大且可通過 -23- 201210463 種子球G之大小的開孔部214a。在開孔板214之四角隅，係 開出螺栓孔2 1 4b，且能夠在該螺栓孔2 1 4b插通螺栓。 保持體（第一保持板211、第二保持板212、第三保持 板213)，係由橡膠等的彈性板所構成。在第一保持板211 ，係於其大致中央形成有直徑比種子球G還更小的第一插 入孔211a。在第二保持板212，係於其大致中央形成有直· 徑比種子球G還更小且比前述第一保持板211之第一插入孔 211a還更大的第二插入孔212a。在第三保持板213，係形 成有與開孔板214之開孔部214a大致相同或是直徑比開孔 部21 4a還更小且直徑比第二保持板212之第二插入孔212a 還更大的第三插入孔213a。換句話說，各自的插入孔211a 、212a、213a之直徑，係依第一插入孔211a、第二插入孔 2 12a、第三插入孔213a之順序而變大。因而，保持體，係 將比藉由配設於上下兩側之第一保持板211、211而形成的 上下最外層還更靠近中間層的保持板之開孔形成較大，且 將比第二保持板212之第二插入孔212a還更靠近其下側的 第三保持板21 3之第三插入孔213a的開孔面積形成較大。 在各保持體211、212、213，係從各插入孔211a、 212a、213a朝半徑方向外方以放射狀形成有複數個裂縫 211b、212b、213b。詳言之，是在形成後述之多角形的保 持體73之頂點方向形成有裂縫211b、212b、213b。在該裂 縫211b、 212b、 213b和裂縫211b、 212b、 213b之間，係分 別形成有保持部（第一保持部211d、第二保持部212d、第 三保持部21 3d )。 -24- 201210463 此等的裂縫21 lb、212b、213b···，係相對於各插入孔 211a、212a、213 a在周方向爲等角度且於半徑方向分別形 成有六條。各保持板211、212、213之全部，係以各自的 裂縫211b、212b、213b之數量及方向爲一致的方式配置。 又，保持板2 1 1、2 1 2、2 1 3，係在以與開孔板2 1 4貼合的狀 態以俯視觀察能夠與螺栓孔2 1 4b—致的位置，形成有螺栓 孑L 21 lc、212c、213c·.·。 藉由如此構成，如第1〇圖（a)所示，種子球G，係首 先被插入於第一插入孔211a，且將第一插入孔211 a近旁的 第一保持部211 d往下推。如第10圖（b)所示，種子球G’ 係可藉由第一保持部211d而被導引至第二保持部212d。進 而如第11圖（a)所示’種子球G，係將第一插入孔211a及 第二插入孔21 2a之近旁的第一保持部211d及第二保持部 212d往下推。如第11圖（b)所示，種子球G’係被導引至 保持板213。然後，種子球G’其最外部分會與第三保持部 213d接觸而使姿態穩定。又’種子球G’其下部會與配置 於最下方的第一保持部211 d之上面抵接。 在此，第三保持部213d，係處於與種子球G大致接觸 的程度。因而，將種子球G插入於種子球保持具21的作業 者，係藉由以感受到較小阻力之程度輕易地插入種子球G 而可保持或載置於最下部的第一保持部211d°藉由因該種 子球G和各保持部211d、212d、213d之接觸而所得的保持 ，作業者就可以插入感覺來確認種子球G已到達能以穩定 狀態保持的的保持空間。 -25- 201210463 藉由加大種子球保持具2 1之上下中間的插入孔之大小 ，就可輕易插入並且可確保（阻力變小）適度的保持力。 如此就能夠容易掌握種子球G之位置，且將種子球G 均一地插入於種子球保持具內。Μ且，藉由種子球G可插 入於種子球保持具21之下方，就沒有抵接於種子球G之下 端部的保持部，如此作業者就可進一步藉由將種子球保持 具21往下方插入，而將種子球載置於配置在最下方的第一 保持部2 1 1 d。換句話說，作業者，係能夠以感覺來確認是 否可將種子球插入至預定位置。因而，可將種子球G以適 當的姿態種植於田地。 前述保持開孔手段2，係具備：保持板211、212、213 ，其係於中央形成有插入孔211a、212a、213a且從該插入 孔211a、212a、213a朝與前述保持體73 —致的多角形之頂 點方向形成有裂縫211b、212b、213b;以及開孔板214， 其係於中央形成有比前述種子球G還更大的開孔部214a， 並使插入孔211a、212a、213a和開孔部214a之中心一致並 交互地重合複數個保持板211、212、213和開孔板214而形 成，且配置於上下方向中央的前述保持板212、213之插入 孔2 1 2a、2 1 3 a，係構成比配置於上下兩側的保持板2 1 1之 插入孔21 la還更大* 由於保持體73之頂點和保持板211、212、213之裂縫 211b、212b、213b—致，所以可在適當姿態下保持種子球 G並確實地種植。換句話說，種子球G係俯視觀察呈大致 三角形，且種子球G之頂點係可配合保持板211之裂縫211b -26- 201210463 、212b、213b而保持。因而，在承繼於推出手段4之導引 構件（保持體73)而推出時，該保持之狀態不會變化而可 由保持體73所保持。結果，在推出時種子球G之芽（發芽 處G1)的方向並不會偏移或落下，而可確實地保持並進行 種植。 又，上下方向中間層的保持板212、213之插入孔212a 、21 3a係形成比上下兩側的插入孔21 la、21 la還更大。因 而，比起形成相同大小的插入孔還可減輕因種子球G和保 持板211、212、213所引起的過大摩擦力，並且可藉由保 持板211、212、213之插入孔211a、212a、213a的內面而 適度地保持種子球G。因而當作業者將種子球G插入於保 持開孔手段2時不會產生較大的摩擦，而可容易插入且不 會傷及種子球。更且，可以適合保持開孔手段2的姿態來 保持種子球G，且可利用推出手段4將種子球G以適當的姿 態種植於田地。 在配置於前述上下兩側的保持板211、211之間所配置 的中間層之保持板212、213之插入孔212a、213a，係越靠 近下側就形成越大。 由於中間層的保持板212、213之插入孔212a、213a， 係形成下側（排出側）的開孔面積比上側（插入側）的開 孔面積還更大，所以可形成內部空間隨著靠近下側而變大 。因此，作業者在插入種子球G時，靠近最下側的的保持 板之前面會在因保持板212、213所引起的新阻力變無、或 被減輕之後，因最下面的保持板2 1 1而再次感受到新的阻 -27- 201210463 力。因而，作業者較容易掌握保持開孔手段2中的種子球G 之插入位置。然後，由於種子球G主要可一邊藉由配置於 上下兩側的保持板211、211以適度之力來保持一邊容易以 適當的姿態插入於保持開孔手段2,所以可藉由推出手段4 以適當的姿態種植於田地。 如第2圖及第7圖至第1 2圖所示，開孔體26，係將四個 板材分別彎曲成側面觀察呈倒L字狀，並將一側轉動自如 地配置於開閉驅動部24。其另一側，係朝下方突出，且以 可將該另一側之前端容易突刺到覆蓋紙1 〇並形成開孔部的 方式，而形成尖狀。 用以開閉驅動開孔體26的開閉驅動器24，係藉由連桿 機構而構成，且配置於前述種子球保持具21和開孔體26之 間。在開閉驅動部24之兩側，係轉動自如地連結有驅動臂 25。驅動臂25之外端係以被推至內方，藉此打開開孔體26 的方式構成。 又，在種植框架1 8之下部內側的前述驅動臂2 5側’係 朝前後方向設置有凸輪體（省略圖示）。凸輪體’係朝內 側突出而形成，俾使前述驅動臂25之外端抵接，且因該驅 動臂25之外端抵接而轉動，藉此開孔體26會在覆蓋紙10形 成開孔部。 換句話說，在驅動臂25之外端與凸輪體相抵接的狀態 下，開孔體26之前端部會位於開口部23a之周圍’且開孔 體26成爲被開啓的狀態。在驅動臂25與凸輪體不抵接’且 驅動臂25朝盒體23之外方突出的狀態下’開孔體26之前端 -28 - 201210463 ，係位於開口部23a之中心部，且開孔體26成爲被閉合的 狀態。 因而，藉由刺入覆蓋紙10後的四支開孔體26之前端， 自開口部23 a之中心往外方轉動，就可在覆蓋紙10之預定 位置形成預定大小的開孔部。 在前述盒體23之左右兩側的上部，係以朝外方突出的 方式配置有支撐軸27、27。在該支撐軸27、27之外周，係 轉動自如地安裝有側面觀察呈L字狀的安裝板28。安裝板 28、28之一面係安裝於前述環狀體3、3之外周上。 如此，保持開孔手段2，係可在補給位置1 7a和種植位 置17b以外的位置，以支撐軸27爲中心而擺動自如地支撐 ，且種子球保持具21之插入軸心可藉由其本身重量而在轉 向鉛垂方向的狀態進行搬運（移動）。 在前述盒體23之左右兩側的下部，係在前後方向隔著 預定間隔以輥子29、29轉動自如地突出的方式配置。在前 述補給位置17a和種植位置17b中，藉由與環狀體3平行地 配置的各導引構件173、174 (參照第7圖）就可限制其搬 運姿態。換句話說，種子球保持具2 1和開孔體26 ’係在補 給位置17a以傾斜預定角度之狀態被搬運’且在種植位置 17b與田地面平行地被搬運〃 其次，使用第5圖至第7圖及第13圖至第15圖，就推出 手段4加以說明。 推出手段4，係藉由保持開孔手段2之開孔體26，而在 被覆蓋紙1 0被覆的田地剛形成有開孔部之後’將由保持開 -29 - 201210463 孔手段2所保持的種子球G朝下方推壓並將種子球G種植於 覆蓋紙10之開孔部下方的田地之手段。推出手段4，主要 是藉由曲柄驅動部5、擺動部6、種植推出部7、導引部8及 卡合部9而構成。 曲柄驅動部5 ’係用以將配置於種植部〗7之左側的第 一種植傳遞機構16a之驅動力傳遞至種植推出部7。曲柄驅 動部5，主要是藉由離合器、轉動臂53、隨動臂54、連結 臂55及上桿支撐體56而構成。曲柄驅動軸5，係分別配置 於種植部17的側部種植框架182 (參照第2圖）之左右外側 ’且以成爲左右一對的方式配置。前述離合器，係由電磁 螺線管50、卡合槓桿51及卡合體52所構成。 前述第一種植傳遞機構16a之推出驅動鏈輪43，係中 介離合器（詳細而言爲卡合體52)而連結於推出驅動軸45 。換句話說，卡合體52，係由外嵌於推出驅動軸45的彈簧 離合器和卡合於該彈簧離合器之一端的卡合盤所構成，且 在卡合盤之外周設置突起，並構成該突起能夠與配置於其 後方的卡合槓桿51卡合。如此，可構成：藉由卡合體52與 卡合槓桿5 1卡合，就可斷開從推出驅動鏈輪43朝推出驅動 軸45之動力的傳遞，且藉由解除卡合，就可從推出驅動鏈 輪43朝推出驅動軸45傳遞動力。又，卡合槓桿51，係與配 置於其近旁之作爲致動器的電磁螺線管50之成爲動作體的 活塞連結。當該電磁螺線管5 0動作時，活塞會被縮小而卡 合槓桿會被轉動，如此卡合槓桿51和卡合體52之卡合可 被解除，並傳遞動力。電磁螺線管50，係控制如下：藉由 -30- 201210463 未圖示之種植位置1 7b附近的限動開關之接通/斷開（限動 開關係檢測保持開孔手段2是否已到達預定位置）而動作 〇 在推出驅動軸45之左右兩端，係分別固定有轉動臂53 之一端。在轉動臂53之另一端部，係貫設有轉動軸54a之 一端（內側）。在該轉動軸54a之另一端（外側），係轉 動自如地配置有隨動臂54之一端。在隨動臂54之另一端， 係有開出貫設孔。在該貫設孔，係貫設有連結軸54b之一 端（外側）。連結軸54b之另一端（內側），係轉動自如 地支撐於連結臂55之上部。 詳言之，在連結臂55之上部，係有開出調節孔55a、 55a、55a，且在該調節孔55a、55a、55a之中的任一個， 貫設有連結軸54b之另一端（內側）。左右的連結臂55之 下部，係橫設有上桿支撐體5 6。 上桿支撐體56，係自上部支撐種植推出體70，且將曲 柄驅動部5之上下運動傳遞至種植推出體70。上桿支撐體 56，係比種植部17之左右寬度還稍短的板體。在上桿支撐 體5 6，係在左右方向隔開預定間隔（與種子球保持具2 1相 同數量且相同位置）安裝有後述的種植推出部7之種植推 出體70。更在上桿支撐體56之左右兩側，配置有在上下方 向具有開口部的圓筒狀之滑動體5 7、5 7，俾於可對後述的 擺動部6之擺動連結體62、62在上下方向滑動自如地嵌合 〇 又’前述曲柄驅動部5之長度調節機構，係在連結臂 -31 · 201210463 55之調節孔55a、55a、55a之中的任一個貫設有連結軸54b ，藉此能夠變更比連結軸54b更靠近下方的長度。換句話 說，藉由變更連結臂55之上下長度，就可調節連結臂55和 連桿（由轉動臂53、轉動軸54a、隨動臂54、連結軸54b所 構成的連桿）之連結長度的上下移動量，並可調整曲柄驅 動部5之升降距離。因而，可變更與曲柄驅動部5之上桿支 撐體56連結的種植推出體70之升降高度，且可將種子球G 之種植深度輕易地變更成所期望深度。因而，如第15圖（ a)所示，藉由在最上方的調節孔55a貫設有連結軸54b， 曲柄驅動部5之整體長度就會變成最長，且種植推出體70 之下端位置會位於最下方，而使種植深度變成最深。又， 如第15圖（c)所示，藉由在最下方的調節孔55a貫設有連 結軸54b，曲柄驅動部5之整體長度就會變成最短，且種植 推出體70之下端位置會位於最上方，而使種植深度變成最 淺。 其次，使用第7圖及第12圖就擺動部6加以說明。 擺動部6，係用以將種植推出部7來與保持開孔手段2 之前後的移動同步並且予以支撐者。擺動部6，主要是藉 由轉動支點軸60、橫設體61、擺動連結體62、下桿支撐體 63而構成。擺動部6，係配置於推出驅動部45之正下方’ 且在前後方向擺動自如地構成。 轉動支點軸60、60，係在推出驅動軸45之正下方，以 從左右的側部種植框架182之上部朝內方突出的方式配置 ，且轉動自如地支撐於側部種植框架1 82 (參照第2圖）。 -32- 201210463 在轉動支點軸60、60，係在各自的內端下部固設有橫設體 61° 橫設體6 1，係使將左右方向當作長邊的板體彎曲成側 面觀測呈大致倒凹字狀的構件。在橫設體61之左右兩端部 ，係固設有將上下方向當作長邊的棒狀之擺動連結體62、 62的上端。在擺動連結體62、62之下端，係固設有與前述 橫設體61大致平行且左右長度也比前述橫設體61還稍短的 下桿支撐體63之兩端。在下桿支撐體63，係形成有能夠滑 動地支撐後述的種植推出部7之種植推出體70的開口支撐 部 6 3 a。 如第13圖及第16圖至第19圖所示，種植推出部7，係 用以將藉由保持開孔手段2而保持的種子球G種植於田地者 。種植推出部7，係藉由複數支（本實施形態中爲四支） 種植推出體70而構成。種植推出體70，係在主種植框架 1 8 1內之空間朝左右方向隔開預定間隔（保持開孔手段2之 開口部23 a的間隔）而配置。種植推出體70，主要是藉由 由導管（guide pipe) 71及保持體73組成導引構件、種植 桿72、由第一刮土板（scraper) 74a及第二刮土板74b組成 的刮土板74、第一彈壓構件75、安裝構件76以及滑動構件 77而構成。 導管71，係將上下方向當作長邊的圓筒狀之構件，且 其上端透過安裝構件76固設在上桿支撐體56。導管71之上 下中途部，係藉由被插入於擺動部6之下桿支撐體63的開 口支撐部63 a而保持成能夠滑動。更且導管71之下部，係 -33- 201210463 能夠上下方向滑動地保持於後述的導引部8之橫向導板81 〇 安裝構件76，係大致圓筒狀的構件，且藉由插入於朝 上下方向形成於上桿支擦體56的開孔，而將導管71安裝於 上桿支撐體56。安裝構件76之內徑，係形成上部比下部還 更大，且以能夠將後述的第一彈壓構件75插入於上部內空 的方式形成。 在導管71內，係上下方向滑動自如地內裝有將上下方 向當作長邊之屬於棒材的種植桿72。該種植桿72，係藉由 比導管71還稍長的棒材而構成。在種植桿72之上部，係安 裝有滑動構件7 7。該滑動構件7 7之上端，係以能夠與延設 於左右方向之固設於連結軸91的接觸構件91a之下面抵接 的方式構成。接觸構件91a係板狀的構件，且以容易與滑 動構件77抵接的方式，在左右方向隔開與種植推出體70相 同的間隔而固設於連結軸9 1。 承接構件77a係環狀的構件，且外嵌於種植桿72。承

a之下端部，係配置爲比安裝部73 a之下端面還更 往下方突出。 ’ 藉此’保持體7 3，會從上方侵入於保持開孔手段2內 ’並容易保持藉由種子球保持具21而保持的種子球G之上 部。 另外，接觸部73b之內周剖面形狀，在本實施形態中 雖然是形成六角形，但是亦可形成五角形、七角形、八角 形、其他的多角形、圓形及橢圓形。又，接觸部73b之內 周剖面形狀，亦非爲限定於正多角形。 又’爲了更進一步加強接觸部73b和安裝部73之接合 ，亦可形成環板狀的突起部，俾於從接觸部73b之上部外 -36- 201210463 周面往外方突出，且將能夠供該突起部嵌合的溝槽形成於 安裝部73 a之內周。 刮土板74，係用以進行當種植桿72進行上下方向之移 動時的導引。刮土板74之中，第一刮土板74a，係用以去 除附著於種植桿72之前端（下端）的泥土等之附著物的構 件。第一刮土板74a，_係形成朝上下方向開口的環板狀。 第一刮土板74a之內徑’係設定爲比種植桿72之下部的外 徑還稍大。第一刮土板74a之外徑’係設定爲比種植部73 a 之上部內徑還更大。第一刮土板74a之上下寬度’係設定 爲比安裝部73 a之溝槽73 c的上下寬度還更小。 第一刮土板74a，係在安裝部73 a內’以使種植桿72插 通於其開口的狀態’使其外周緣部嵌入於溝槽73c’並在 該溝槽7 3 c內以能夠朝上下方向滑動的方式配置。 第二刮土板74b，係用以去除並未被第一刮土板74a去 除掉的種植桿72之附著物的構件。第二刮土板74b ’係形 成朝上下方向開口的環狀’且側面觀察形成凸狀。第二刮 土板74b之內徑，係設定成與種植桿72之下部的外徑大致 相同。第二刮土板7 4b之上部（縮徑部）外徑，係設定成 與導管71之內徑大致相同。第二刮土板7 4b之下部（擴徑

植桿72之上升，並使導管71先上升，且藉由種植桿72強制 性地推出保持體7 3內的種子球G。卡合部9，主要是藉由配 置於連結軸9 1之兩側的上部卡合體9 0、和配置於下桿支撐 體63之兩側的下部卡合體290而構成。 卡合部9之構件，由於是左右對稱所以僅說明左側的 構成。 上部卡合體90，係在左右的種植推出部7之上方以成 爲左右一對的方式分別配置於滑動體5 7近旁的上桿支撐體 56。上部卡合體90，主要是藉由連結軸91、第一支撐構件 92、第二支稱構件93、上部卡合構件94、第二彈壓構件95 、限制構件96等而構成。 第一支撐構件92，係藉由板狀的構件而構成，且其下 部側面是與固設於連結軸91的接觸構件91a固設。在第一 支撐構件92係貫通有連結軸9 1之一側，且連結軸9 1之兩側 係被插入於後述的限制構件96之長孔96a。又，從第一支 撐構件92之內側的側面突設有限制突起92a，且以能夠與 上部卡合構件94之一側下面抵接的方式配置。 第二支撐構件93，係藉由板狀的構件而構成，且於其 上下中途部貫通固定有連結軸91，並與第一支撐構件92平 行地配置。從第二支撐構件93之下端部朝機體外方突設有 卡止突起93a。 上部卡合構件94，係具有前板以及位於前板之左右的 -38- 201210463 側板，且由俯視觀察被折彎成大致呈Π字狀的板狀構件所 形成。在上部卡合構件94之左右側板的前後中途部，係貫 通支撐有轉動支點軸94a。該轉動支點軸94a之兩側，係轉 動自如地支撐於第一支撐構件92及第二支撐構件93之上部 。換句話說，上部卡合構件94，係配置於第一支撐構件92 和第二支撐構件93之間，且以轉動支點軸94a爲中心而轉 動自如地支撐於第一支撐構件92及第二支撐構件93。在上 部卡合構件94之左右側板的後部，係橫設有可供圓筒狀之 軸環94c貫設的抵接軸94b。在上部卡合構件94之前板，係 形成有卡止孔94d。 第二彈壓構件95,係藉由拉伸彈簧而構成，且其上端 是飽止於上部卡合構件94之卡止孔94d，而其下端是飽止 於卡止突起93a。另一方面，在第一支撐構件92及第二支 撐構件93，係以往上部卡合構件94之內側方突出的方式配 置有用以限制上部卡合構件94之前部往下方轉動的限制突 起 92a、93b。 因而，上部卡合構件94之前部，係可藉由第二彈壓構 件95以轉動支點軸94a爲中心而朝下方向（參照第19圖之 箭頭B )彈壓，並且藉由限制突起92a、93b而限制朝比第 19圖所示的狀態還更靠近下方轉動。 限制構件9 6，係藉由將上下方向當作長邊的板材而構 成，且於其上部形成有將上下方向當作長邊的長孔96a ° 限制構件96之下端，係固設於比滑動體57還更靠近機體內 側的上桿支撐體56。在長孔96a ’係分別滑動自如地貫設 -39- 201210463 前述連結軸9 1及轉動支點軸94a之左端部（外端部）。 下部卡合體2 90，係在種植推出體70位於最上方的種 植待機狀態（參照第1 3圖）中，配置於左右兩側所配置的 上部卡合構件94之後下方的下桿支撐體63。下部卡合體 2 90，主要是藉由下支撐構件291、上支撐構件292、由第 一下卡合構件293及第二下卡合構件294組成的下卡合構件 、轉動支點軸295、及第三彈壓構件296而構成。 下支撐構件291，係藉由將上下方向當作長邊的二片 板材而構成，且其下前端是隔開左右預定間隔而固設於下 桿支撐體63之兩側後部。在下支撐構件291，係在上下空 出預定間隔而形成有複數個開孔部。 上支撐構件292係藉由板材而構成，且以具有後板和 位於後板之左右的側板之方式俯視觀察形成前方開放的大 致U字狀。上支撐構件292之後板的上部，係有缺口，且形 成上端比左右側板還更低。在上支撐構件292之後板，係 以卡止支撐構件292a、292a於左右隔開預定間隔往後方突 出的方式配置。在卡止支撐構件292a、292a間，係左右橫 設有卡止軸292b。在上支撐構件292之左右側板的下部， 係形成有與前述下支撐構件2 9 1隔開同等間隔的複數個開 孔部。上支撐構件292和下支撐構件291，係在使其等的開 孔部以側面觀察呈一致的狀態下，藉由利用螺栓等使其貫 設並緊固而一體化。又，由於形成有複數個開孔部，所以 藉由變更使其一致的開孔部，就能夠進行下部卡合體290 之高度調節。 -40- 201210463 配置於上支撐構件2 92之上部的下卡止構件，係藉由 第一下卡合構件2 93及第二下卡合構件2 94而構成。 第一下卡合構件293及第二下卡合構件294，係分別藉 由板狀的構件而構成。第一下卡合構件2 93之上部和第二 下卡合構件294之下部，係分別以重疊成爲一體的方式固 設。第一下卡合構件2 93之前下部，係轉動自如地支撐於 橫架在上支撐構件292之上部的轉動支點軸295。更且，在 第一下卡合構件293之後下部，係橫架有卡止軸293 a。 第二下卡合構件294之上前端，係形成有以側面觀察 呈傾斜爲前低後高的傾斜邊294a。第二下卡合構件294之 上部，係形成比第一下卡合構件293之前端還更往前方突 出，且形成卡止部。第一下卡合構件293和第二下卡合構 件2 94，係整體以側面觀察形成鉤針狀。 第三彈壓構件296，係由壓縮彈簧等所構成，且用以 彈壓第一下卡合構件293之下端和卡止支撐構件292a、 292a間。在第三彈壓構件296，係插入有板狀的插入板297 。插入板297之一端（上端）係卡止於卡止軸293a，而另 —端（下端）是卡止於卡止軸292b。插入板297之另一端 ，係形成有長孔2 9 7 a，且能夠供卡止軸2 9 2 b滑動地貫設於 該長孔297a。 如第7圖、第12圖及第22圖所示，導引部8，係用以使 位於種植位置17b的種植推出部7和保持開孔手段2之後方 移動同步的構造體，且配置於種植部17之下部。 導引部8，主要是藉由側部導引板80、橫向導引板81 -41 - 201210463 、導引軸84、同步導引棒85及拉伸構件86而構成。 側部導引板8 0，係由將前後方向當作長邊的板材所構 成’且以成爲左右一對的方式配置於側部種植框架182之 下部。在側部導引板80之前後部，係形成有同一形狀的開 口部80a、8 0a。開口部80a，係以從其前端至中途部開口 成大致水平，且從中途部至後端成爲前低後高的方式開口 。換句話說，開口部80a係開孔成大致倒「\」字狀的長 孔。 橫向導引板8 1，係形成剖面觀察大致呈倒U字狀，且 從該橫向導引板8 1之左右兩側端部的前後兩側分別使導引 軸84、84、84、84朝側方突設，而該導引軸84、84、84、 84之前端部被插入於前述左右的開口部80a、80a、80a、 8 0 a並前後滑動自如地支撐。 橫向導引板8 1，係在左右方向隔開預定間隔而形成有 開孔。該開孔，係以能夠供導管7 1之下端部滑動的方式配 置。 同步導引棒85，係將上下方向當作長邊的棒材，且以 從保持開孔手段2之左右兩側朝下方突出的方式配置。同 步導引棒85，係用以在環狀體3環繞時，會與固設於環狀 體3之外周的安裝板28抵接，且導引部8會與保持開孔手段 2之後方移動同步而移動的構件。同步導引棒85之上端， 係固設在橫向導引板81之左右兩端部的前後中途部。詳言 之，在橫向導引板81之兩端部開出貫設孔’且在該貫設孔 貫設前述同步導引棒85之上端並利用螺帽等使同步導引棒 -42- 201210463 8 5和橫向導引板81緊固。 拉伸構件86，係藉由在兩端部具有鉤的拉伸彈簧而構 成。拉伸構件86、86之一端，係卡止於被固定在左右的側 部種植框架182之安裝構件87、87，且另一端卡止於前側 的導引軸84、84。如此，橫向導引板81可以藉由拉伸構件 8 6朝前方向被拉伸的方式彈壓。 其次，就配置在種植框架18內的種植部17之各種植裝 置的動作加以說明。 首先，使用圖式就保持開孔手段2和推出手段4之同步 運動來加以說明》 保持開孔手段2，係在種植作業時，如第22圖（a )所 示，藉由環狀體3轉動，保持開孔手段2就會在種植位置 17b中從前方朝後方移動。此時，藉由導引部8的同步導引 棒85、85之下端抵接於保持開孔手段2之安裝板28，固定 有橫向導引板81的橫向導引板81就會往後方移動。然後， 如第22圖（b )所示，從橫向導引板81朝側方突設的導引 軸84、84、84、84，係順沿側部導引板80的開口部80a、 80a、80a、8 0a之水平部，換句話說，被導引並一邊滑動 一邊朝後方移動。 當保持開孔手段2更進一步往後方移動時，如第22圖 (c)所示，導引軸84係沿著開口部80a之傾斜部而往後上 方移動。藉由往該保持開孔手段2 (橫向導引板8 1 )之後 上方的移動，同步導引棒85'、85就會被往上舉起，且同步 導引棒85、85之下端會比保持開孔手段2之安裝板28還更 -43- 201210463 朝上方移動，當同步導引棒85、85和保持開孔手段2之抵 接消除時，藉由往拉伸構件86之前方向的彈壓力，橫向導 引板81就可往前方送回。換句話說，各導引軸84可移動至 各開口部80a之前端，且同步導引棒85、85之下端能夠抵 接於位在前方的下一個保持開孔手段2之安裝板28。 在橫向導引板81，係滑動自如地支撐有導管71之下端 部。因此，導管71也會因與橫向導引板81之動作連動而移 動。導管7 1，係可滑動自如地支撐於配置在比橫向導引板 81還更靠近上方的擺動部6之下桿支撐體63。由於擺動部6 是以轉動支點軸60爲中心而轉動自如地支撐，所以導管7 1 會以轉動支點軸60爲中心而朝前後方向移動。 因而，藉由橫向導引板81而保持的種植推出部7，係 能夠如第12圖般地在種植位置17b相對於往保持開孔手段2 之後方的移動而使其同步移動（擺動），且在種植時，可 將種植推出部70之下部確實地插入於保持開孔手段2之開 口部 23a。 其次，使用圖式就用以將種子球G種植於田地的推出 手段4之動作加以說明。 如第6圖、第7圖、第13圖及第14圖所示，當保持開孔 手段2到達種植位置17b之預定位置時就會抵接於限動開關 之接點並成爲ON (接通）。然後，與限動開關連接的電 磁螺線管50會動作，且卡合槓桿51會轉動而從卡合體52脫 落。如此，卡合體52會與推出驅動軸45卡合而一體地轉動 ，且動力可傳遞至推出驅動軸45。因而，左側的推出驅動 -44- 201210463 鏈輪43之旋轉力，可傳遞至推出驅動軸45，且如第14圖所 示，使固設於推出驅動軸45之左右的轉動臂53旋轉。另外 ，前述限動開關係可藉由抵接部通過而於之後變成OFF ( 斷開），且電磁螺線管50會回到原來的位置。然後，當卡 合體52進行一旋轉時，會再次與卡合槓桿51卡合，而從卡 合體52往推出驅動軸45之動力傳遞會被斷開。當該推出驅 動軸45進行一旋轉時，與此連結的轉動臂53也會進行一旋 轉，且使隨動臂54—邊前後擺動一邊朝上下移動，如此上 桿支撐體56就可從該隨動臂5 4透過連結臂55而連動並朝上 下移動。 在上桿支撐體56，係安裝有種植推出部7的種植推出 體70、70、70、70之上部。因此，種植推出體70就可與上 桿支撐體56之上下的移動連動而朝上下移動。更且，在上 桿支撐體56，係透過左右一對的滑動體57，以能夠滑動於 擺動連結體62的方式配置。因此，種植推出體70，係與擺 動部6之前後方向的移動連動，並以轉動支點軸6 0爲中心 而朝前後方向移動，並且毫無勉強地在上下移動。 換句話說，藉由曲柄驅動部5之動作，種植推出部7就 會進行上下移動。 又，當藉由曲柄驅動部5之動作，種植推出部7移動至 下方時（參照第14圖（c)) ’就可將種子球G種植於田地 〇 其次，就種植推出體70之種植的動作加以說明。 藉由曲柄驅動部5的上桿支撐體56之下方移動，種植 -45- 201210463 推出部7會朝下方移動。因此，如第19圖所示，上部卡合 體90和固設於上桿支撐體56的限制構件96，會如第23圖所 示，均接近下部卡合體2 90之第二下卡合構件2 94，而上部 卡合體90之軸環94c，會接觸到第二下卡合構件294之傾斜 邊 2 9 4 a。 更且，藉由上部卡合體90朝下方移動，軸環94c就會 沿著傾斜邊294a而推壓第二下卡合構件294。因而，下卡 合構件（293、294 )，係抵抗第三彈壓構件296 (參照第 23圖）之彈壓力並以轉動支點軸295爲中心而朝箭頭C方向 轉動。此時，由於上部卡合構件94之下前部係接觸到限制 突起92a、93b，所以不會以轉動支點軸94a爲中心往前方 轉動而軸環9k會推壓第二下卡合構件294。又，由於第二 下卡合構件294被推壓，所以第三彈壓構件29 6會朝大致上 下方向壓縮，且插入板297之長孔297a的上端會使與卡止 軸292b接觸的方式移動。 更且，當軸環94c到達傾斜邊294a之下部時，下卡合 構件（293、294 )，係可藉由第三彈壓構件296之上下方 向的彈壓力，以轉動支點軸29 5爲中心而朝D方向轉動。此 時種植推出體70及上部卡合體90，係成爲最下位。 另一方面，此時，如第22圖所示，保持開孔手段2， 係可藉由配置於種植位置17b的凸輪體來抵接驅動臂25之 外端，且藉由開孔體26朝外方轉動，而在被覆於田地的覆 蓋紙1〇形成開孔部。 之後，如第25圖及第26圖所示，配置於下方移動中的 -46- 201210463 導管71之下端部的保持體73，會從上方侵入於保持開孔手 段2，且保持由種子球保持具21所保持中的種子球G。保持 體73，係一邊保持種子球G，一邊與種子球G同時進行下 方移動。導管71之保持體73係在將其位置到達最下部的同 時，將種子球G朝覆蓋紙1 0之開孔部下方的田地推壓（參 照第2圖）。 之後，藉由曲柄驅動部5往上桿支撐體56之上方的移 動（參照第14圖（d))，種植推出部7就會朝上方移動。 另一方面，卡合部9，係如第24圖及第27圖所示，由 於軸環94c被卡止於下卡合構件（293、294 )，所以隨著 上桿支撐體56之上升，卡合部9之中，僅有固設於上桿支 撐體56的限制構件96會上升。但是，除了限制構件96以外 的上部卡合體90，會停止其上升直至連結軸91與長孔96a 之下端相接爲止。藉由上桿支撐體56之上升，透過安裝構 件76而固設於上桿支撐體56的導管71就會上升。 此時，上桿支撐體56，係抵抗第一彈壓構件75之彈壓 力，並透過安裝構件76及承接構件77a使第一彈壓構件75 壓縮，而一邊縮短安裝構件76和滑動構件77之間一邊固設 於滑動構件77的種植桿72係在保持原來狀態之位置僅使導 管71上升。 另一方面，此時，當著眼於第17圖所示的種植推出部 7之下端時，種植桿72會因受到連結軸9 1抑制而可保持其 高度，且連結於導管71的保持體73，在上升預定高度之後 ，種植桿72會上升。因而，種植桿72會壓住種子球G之上 -47- 201210463 部，而僅有導管71及保持體73會朝上方移動，田地的種子 球G，可從保持體73之保持狀態獲得解除，並種植於田地 。更且，在剛種植完之後，即便是在保持體73內附著有泥 土等的異物之情況，也會因種植桿72比導管71及保持體73 還更晚上升，而可使種植桿72將保持體73內之泥土往下方 推出。然後，隨著導管71之上升第一刮土板74a就會去除 停留在其下面的種植桿72之附著物，更且可藉由第二刮土 板74b去除未被第一刮土板74a去除乾淨的附著物。又，藉 由第二刮土板74b而去除的附著物係從第一刮土板74a之開 口部掉落。 更且，藉由第14圖（c)及（d)所示的曲柄驅動部5 的上桿支撐體56之上方移動，如第28圖所示，滑動構件77 會將接觸構件91 a往上方推壓，並且限制構件96之長孔96a 的下端會將連結軸91往上方推壓。 藉由該二個推壓力，上部卡合體90就會上升。又，由 於軸環94c被卡止於第二下卡合構件294，所以轉動支點軸 94a會因抵抗第二彈壓構件95之彈壓力而上升，上部卡合 構件94就成爲以轉動支點軸94a爲中心而朝下方轉動的姿 態。 ' 藉由更進一步的上部卡合構件94之上升，軸環94c就 會一邊轉動於抵接軸94b之外周一邊上升，而與第二下卡 合構件294之卡合可被消除。上部卡合構件94，係如第19 圖所示，會藉由第二彈壓構件95之彈壓力而回到原來的位 置。相同的’第一彈壓構件75，係藉由其彈壓力，並透過 -48- 201210463 滑動構件77將接觸構件91 a往上方向推壓，且使除了限制 構件96以外的上部卡合體90上升。因而，轉動支點軸94a 會與限制構件96之長孔96a的上端抵接。 此時，種植桿72會如第12圖及第13圖所示與導管71 — 起往上方移動。然後，藉由前述的導引部8，導管71就會 以轉動支點軸60爲中心而往前方返回，而導管7

右中央之二支種植推出體70、70而言，係透過卡合部9之 連結軸91及左右中央之接觸構件91a、91a來進行。換句話 說，與配置在左右兩側的種植推出體70、70之種植桿72、 72大致同樣，機體左右中央之二支種植桿72、72，係隨著 連結軸9 1之上下的移動而有所行動。 藉由如此構成，比起種植桿72、72、72、72—體地連 結於連結軸9 1，還更可減少種植損失，且更可有效率地進 行種植作業。 以下，就從由保持開孔手段2所保持的種子球G往保持 體73之保持的移行及保持體73之種子球G的保持狀態加以 -49- 201210463 說明。 如第18圖及第25圖所示’例如，種子球G爲蒜頭之種 子球的情況，種子球G，係當將根側當作下方時以俯視觀 察大致成爲二等邊三角狀。以相當於該二等邊三角形之底 邊的部分朝相對於種植行進方向（箭頭A)呈正交的方向

具21，亦可在前後反方向、向右或向左插入於種子球保持 具2 1並予以保持。 在前述狀態下藉由保持開孔手段2而保持的種子球G， 係在種植位置17b (參照第7圖），藉由種植推出體70之保 持體73來保持，以取代保持開孔手段2，並朝下方移動。 詳言之，如第25圖及第26圖所示，保持體73之下端， 係在侵入於保持開孔手段2內之後，會抵接於種子球保持 具21之上部的保持部21h，且朝下方移動，並且將抵接於 種子球G的種子球保持具21之保持部21 h往下方推寬。換句 話說，種子球G，係隨著往保持體73之下方的移動而將取 決於種子球保持具21的保持狀態從其上部慢慢地解除，且 與接觸部73b接觸，藉此不改變姿態就可以保持體73來保 -50- 201210463 持，以取代種子球保持具21° 此時，如第1 8圖所示’保持體7 3 ’係在俯視觀察中’ 使種子球G之發芽處G1近旁的側面及後部之二個頂點抵接 於側面部73d，並藉由接觸部73b來保持種子球G。 在保持體73藉由接觸部73b來保持種子球G時’雖然有 依種子球G之形狀，而使二個頂點所包夾的側面抵接於側 面部73 d，或使二個頂點抵接於角部73 e的情況，但是即使 是在該時也可使種子球G之姿態以與由保持開孔手段2所保 持的姿態大致相同的姿態來保持。 種子球G，係在側面觀察中，發芽處G 1側，比根側還 更縮徑的形狀。因此，俯視觀察中的種子球G之三處頂點 ，係以線及面來與柔軟地將形狀予以改變的保持體73中的 接觸部73b之側面部73d相接。換句話說，保持體73，係至 少以三處的線或面來與種子球G接觸。因而，當種植推出 體70朝下方移動時，就可使種子球G—邊穩定保持一邊移 動。 如以上所述，本實施形態的種植機1，係具備行走部 14、以及進行種子球之種植的種植部17，且一邊行走於田 地一邊朝行走方向以每一種植間隔P (預定間隔）進行種 子球G之種植的種植機，前述種植部17，係具備：保持開 孔手段2(保持手段），其係用以保持種子球G;以及推出 手段4 ’其係將由前述保持開孔手段2所保持中的種子球G 往田地一邊推出一邊種植，前述推出手段4，係具備：筒 狀的導管7 1 (導引構件），其係使由前述保持開孔手段2 -51 - 201210463

保持該種子球G。因而，藉由種植桿72推出由保持體73所 保持的種子球G，藉此就可以保持原來狀態之適當姿態種 植於田地。結果，被種植於田地的種子球G之姿態變佳， 且作物均一地成長。 ‘ 本實施形態的種植機1，係將前述保持體73以軟質材 料來構成。 藉由如此構成，就能夠加大保持體73之與種子球G的 接觸面積，且容易將種子球G以適當的姿態保持於保持體 73。因而，可將種子球G以適當的姿態種植於田地。而且 ，因保持體73柔軟地接觸於種子球G之外周面故而不會傷 到種子球。 (產業上之可利用性） 本發明係能夠利用於將種子球種植於田地的種植機之 技術中。 -52- 201210463 【圖式簡單說明】 第1圖係顯示本發明之一實施形態的種植機之構成的 後方斜視圖。 第2圖係顯示第1圖的種植機之整體構成的側視圖。 第3圖係顯示本發明之另一實施形態的第二輔助供給

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a planter, and more particularly to a technique for planting seed balls in a field planter. [Prior Art] Conventionally, the seed ball of garlic and the like has been planted in such a manner that the bud of the seed ball becomes the upper side and the root of the seed ball becomes the lower side. Improper planting will be associated with a reduction in harvest and a reduction in grade due to poor germination. Therefore, in order to harvest high-quality crops, it is necessary to carry out seed planting by hand. However, when the seed ball is cultivated as a commercial crop, the operator has a large burden on the manual due to the expansion of the agricultural area. Therefore, there are a variety of planting machines that propose seeding of seed balls in the field. For example, the planter disclosed in Patent Document 1 is provided with: a holder for temporarily holding a crop (seed ball) before planting; and an upper and lower mechanism for holding the holder between the accommodating position and the planting position Cycling; and launching a stem that pushes and implants the crop contained in the holder: and an up and down mechanism that moves the pusher bar up and down. In the planting machine, the stem portion is inserted from the upper end portion of the holder which is moved to the planting position, and the crop contained in the holder is pushed downward by the pushing rod portion, whereby the crop can be planted in the field. (Patent Document 1) Japanese Laid-Open Patent Publication No. 2009-213359 (JP-A) No. JP-A-2009-2012 The stability of the stem is poor, and the ball cannot be planted in the field in an appropriate posture. Therefore, the object of the present invention is to provide a planter that is planted in the field. (The means to solve the problem) in Shen. In the middle of the first paragraph of the patent scope, and in the planting of the seed ball, each of the predetermined inter-machines is in the direction of walking. The planting department has: a ball for the ball; and a launching method, which is to be pushed out from the ball to the field. Planting a cylindrical guide member for moving the seed ball to the field; and planting the member and planting it by moving the guiding member, wherein the guiding member maintains the retention of the seed ball The body has a cylindrical shape and an angular shape that is opened to the holding means. It is composed of a holder in the planter and a launching posture. Therefore, there is a case where the seed land pushed out by the stem portion is introduced. A planting means for planting a seed ball with a seeding ball and a walking planting portion, and walking on the field to carry out the seed ball, which is used to maintain the seed in the seed holding means The above-mentioned pushing means is a rod held by the holding means, and the seed ball mounted in the guiding structure is pushed out toward the field to provide a holding body for moving the seed ball. In the second aspect of the patent application, the retaining system is composed of a soft material 201210463. In the third aspect of the patent application, the holding means is such that: the holding plate is formed with an insertion hole formed in the center thereof, and a crack is formed from the insertion hole toward a vertex of the polygon conforming to the holding body; and The orifice plate is formed with a larger opening portion than the seed ball in the center, and is formed by alternately overlapping a plurality of the insertion holes and the center of the opening portion, and is disposed at the center in the vertical direction The insertion holes of the holding plates are larger than the insertion holes of the holding plates disposed on the upper and lower sides. In the fourth aspect of the patent application, the insertion hole of the holding plate of the intermediate layer disposed between the holding plates on the upper and lower sides is formed to have a larger opening area as it is closer to the lower side. (Effect of the Invention) As an effect of the present invention, the effects described below can be achieved. In the first item of the patent application, when the seed ball is planted in the field, the body is held in contact with the outer surface of the seed ball at a plurality of places, and the seed ball is held in an appropriate posture. Therefore, the seed ball held by the holder is pushed out by the planting rod, whereby the appropriate posture in the original state can be planted in the field. In the second item of the patent application, when the holding body holds the seed ball, the holding body is deformed in conformity with the shape of the seed ball, whereby the contact area of the holding body with the seed ball can be increased, and the posture of the holding body is easily adapted. To keep the seed ball. Thus, the seed ball can be planted in the field in an appropriate posture. Moreover, since the holder is softly contacted with the outer surface of the seed ball, the seed 201210463 is not injured. In the third item of the patent application, since the apex of the holding body and the crack of the holding plate are identical, the seed ball can be held while the proper posture is maintained, and the planting operation can be appropriately performed. Here, in general, the seed ball has a substantially polygonal shape in a bird's eye view. In other words, the apex of the seed ball can be held in conjunction with the crack of the retaining plate, and the retaining state does not change and can be retained by the retaining body when pushed out by the guiding member of the pushing means. Therefore, the direction of the bud of the seed ball does not shift or fall when pushed out, and can be surely maintained and planted. Further, the insertion holes of the holding plates of the intermediate layer in the up-and-down direction are formed to be larger than the insertion holes on the upper and lower sides. Therefore, the excessive friction caused by the seed ball and the holding plate can be alleviated as compared with the formation of the insertion hole of the same size, and the seed ball can be appropriately maintained by the inner surface of the insertion hole of the holding plate. When the seed ball is inserted into the holding means, no large friction is generated, and the seed ball can be easily inserted without damaging the seed ball. Further, the seed ball can be held in a posture suitable for maintaining the means, and the seed ball can be planted in the field in an appropriate posture by means of pushing means. In the fourth aspect of the patent application, the insertion hole of the holding plate of the intermediate layer has a larger opening area on the lower side (discharge side) than on the upper side (insertion side). In other words, the internal space formed becomes larger as it approaches the lower side. Therefore, when the operator inserts the seed ball, the front surface of the holding plate near the lowermost side will feel new resistance again due to the lowermost holding plate after the new resistance depending on the holding plate is not changed or reduced. . Therefore, it is easier for the operator to grasp the insertion position of the seed ball in the holding means. -8- 201210463 Then, since the seed ball can be inserted into the holding means by an appropriate posture while being held by the holding plate disposed on the upper and lower sides with a moderate force, it can be planted in an appropriate posture by the pushing means. In the field. [Embodiment] Next, an embodiment of the invention will be described. In addition, it is assumed that the ridge is covered with a mulch sheet, but it is not particularly limited to this.

The planting frame 18 is mainly constructed by a main planting frame 181, a side planting frame 182 and a lateral planting frame 183. As shown in FIGS. 1 to 5, the main planting frame 181 is formed by bending a bar member or the like into a polygonal shape in which the rear portion and the lower portion are open in side view, and is spaced apart from the left and right body widths. A short interval is arranged to be a pair of left and right. When specified in detail, the main planting frame 181 is formed such that one end thereof is located above and below the rear portion of the planting portion 17. A rear inclined portion 18a is formed in such a manner as to be from the rear end of the main planting frame 181 toward the front upper side so as to be front high and low. Further, at the upper portion of the planting portion 17, a horizontal portion 18b is formed. The front upper inclined portion 18c is formed in such a manner that the front upper portion becomes the front lower rear height as seen from the front portion of the horizontal portion 18b. The front lower inclined portion 18d is formed in such a manner as to be from the lower portion of the front upper inclined portion 18c toward the center of the planting portion 17 so as to be front high and low, and then the other end of the main planting frame 181 is placed in front of the lower portion of the planting portion 17. form. The side planting frames 182 are disposed in the vertical direction and the front and rear directions of the left and right main planting frames 181 and 181. A lateral planting frame 1 8 3, 1 8 3 is disposed laterally between the left and right main planting frames 181 and 181. -10- 201210463 According to this configuration, the planting frame 18 has a space formed therein, and various planting devices to be described later can be disposed in the space. Further, the main planting frames 181, 181 can be covered by the cover member 171 to cover the left and right outer sides thereof. On the inner side of the main planting frames 181 and 181, the annular body cover member 172 is disposed to protrude inward. The drive unit 13 is composed of an engine 131 as a power source, a generator (not shown), and the like, and transmits power to the traveling unit 14 and the planting unit 17 to drive the respective units. The driving unit 13 is mounted on the rear portion of the body frame 12, and is disposed so as to obtain a weight balance between the front and rear directions of the planting portion 17 coupled to the front portion of the body frame 12. Above the driving unit 13, a placing portion 154 for arranging the basket 153 or the like in which the seed ball G is housed is disposed. The traveling unit 14 is constituted by a pair of right and left crawlers 140 and 140, and the power from the driving unit 13 is transmitted through a transmission case 141, whereby the planting machine 1 can be moved. The operation operation unit 15 is disposed in the center portion before and after the body frame 1 2, and can perform manipulation of the traveling portion 14 and the planting portion 17.

Above the operation tower 152, a clutch lever, a travel clutch lever, a side clutch lever, a plant height automatic adjustment switch, and a walking direction automatic adjustment switch are disposed. After the operation tower 1 52, an engine stop switch, a plant lift switch, a planting drive switch, and the like are disposed. In the present embodiment, the traveling shift lever for shifting the traveling speed of the planter 1 is disposed on the right side below the right seat 151. The seed ball replenishing portion 197 shown in Figs. 1 and 2 is for temporarily storing a seed ball for replenishing the holding opening means 2 to be described later. The seed ball replenishing unit 1 9 is mainly constituted by a supply tank 191 and an auxiliary supply tank 1 92. -12- 201210463 The supply box 191 is a container that can be temporarily accommodated before the insertion of the seed ball G inserted into the planting unit 17 and holding the opening means 2. The supply tank 191 is formed into a substantially gutter-shaped container which is slightly shorter than the left and right widths of the planting portion 17, and has an upper portion open and closed at both left and right ends. The left and right side portions of the supply tank 191 are fixed to the inner side of the rear inclined portion 18a of the main planting frame 181, and the rear end of the annular body cover member 172. The auxiliary supply tank 1 92 is for supplying a new seed ball G to the supply tank 191. The auxiliary supply tanks 192 and 192 are disposed on the upper and lower cover members 171 and the upper surface cover member 172 as a pair of right and left. The auxiliary supply tank 192 is mainly constituted by the accommodating portion 193, the induction portion 194, and the partitioning plate 195. The accommodating portion 193 is an open substantially box-shaped container and is used to store the seed ball G. The accommodating portion 193 is fixed to the upper surface of the lid member 171 and the annular body lid member 172 by means of a sandwich mounting member (not shown). The side of the holding opening means 2 of the accommodating portion 193 is disposed so as to be substantially at the same position in the left-right direction. The outer side of the housing portion 193 is disposed more prominently than the outer side surface of the cover member 171. The rear portion of the accommodating portion 193 is disposed so as to project rearward and downward to the front and rear portions of the rear inclined portion ISa along the upper surface of the rear slanting portion ISa along the upper surface of the inclined portion 18a and the annular body cover 172 along the lid member 171 and the main planting frame 181. An opening is formed on the side of the holding opening means 2 at the rear portion of the protruding portion. The inducing portion 194 is a substantially tunnel-shaped member and is a passage for supplying the seed ball G in the accommodating portion 193 to the supply tank 192. The inducing portion 194 is fixed to the upper surface of the annular body cover member 172 and the rear inclined portion -13 - 201210463 18a behind the accommodating portion 1 93. One end (upper end)' of the inducing portion 194 is connected to the opening of the gull portion 193. The other end (lower end) of the inducing portion 194 is disposed above the right and left end portions of the supply tank 191. The other end of the induction portion 194 is formed with an opening on the side of the supply tank 191. The partition plate 195 is for preventing the clogging of the seed ball G in the passage of the inducing portion 194. The partition plate 195 is constituted by a plate-like member having substantially the same width as the left and right of the induction portion 194. The partition plate 195' is placed on the upper side of the induction portion 194, and the passage cross section in the induction portion 194 is disposed so as to become larger toward the downstream side from the upstream side in the supply direction of the seed ball G. Further, the partitioning plate 195 is formed such that its upper end portion is bent toward the upper surface of the inducing portion 194 and is attached to the upper surface. With this configuration, the cross section of the passage closer to the downstream side than the upstream side of the induction portion 194 becomes larger, and the seed ball G is easily supplied to the supply tank 191. In the above configuration, the operator takes out the seed ball G in the supply tank 191 by hand and inserts it into the holding opening means 2. In addition, since the supply tank 191 is configured to be connected to the left and right, the seed ball G in the supply tank 191 on the left and right sides is easily turned to the side when the seed ball G in the front side of the operator on the left and right sides becomes empty. Move and add the seed ball G. Further, when the seed ball G at the end of the supply tank 191 is reduced, the seed ball G can be supplied from the accommodating portion 193 of the auxiliary supply tank 192 via the inducing portion 194 and by the weight of the seed ball G toward the supply tank 191. . Therefore, the operator can reduce the shortage of the seed ball G in the supply tank 191, and the planting operation can be stopped, and the planting operation can be performed efficiently. -14 - 201210463 In addition, if the seed ball G in the supply tank 911 and the auxiliary supply tank 1 92 is not available, the seed ball G can be replenished from the basket 153 behind the seat 151 to the supply box 119 and the auxiliary Supply box 1 92. Further, a second auxiliary supply tank 3 92 may be provided as another embodiment instead of the auxiliary supply tank 1 92 of the present embodiment. As shown in Figs. 3 and 4, the second auxiliary supply tank 392 is mainly constituted by the accommodating portion 393, the induction portion 394, and the partition portion 395. The basic structure of the housing portion 393 and the inducing portion 394 is the same as that of the housing portion 193 of the auxiliary supply tank 192. The accommodating portion 3 93 is fixed so as to be able to support the partitioning portion 3 95 to be described later, and the bolts 3 93 a and 3 93 a are spaced apart from each other at a predetermined interval in the vertical direction and projecting rearward and downward at the lower rear inclined surface. The inducing portion 394 is formed with an insertion hole 394a » a partition portion 3 95 on the side of the outer surface of the body adjacent to the mounting portion of the accommodating portion 393, and forms a door structure. Specifically, the plate-shaped member is divided into The partition plate 395a is formed to be curved so as to be at a right angle to the partition plate 395a. In the partition plate 395a, long holes 3 95c and 3 95c which are long sides in the left-right direction are formed at intervals corresponding to the above-described bolts 393a. The partition plate 395a can be inserted into one end (inside of the body) into the insertion hole 394a of the induction portion 394. The long holes 395c, 3 95c can be fastened by the bolts 3 93 a, 393 a formed in the receiving portion 393 and fastened by the nuts 3 93b, 3 93b and along the receiving portion 3 93 The partition plate is fixed in a manner of a rear bevel 3 5 5 a. Therefore, the operator slid the bolts 393a, 393a to the long holes 3 95 c, 3 95 c while holding the handle plates 395b while releasing the nuts 393b, 3 93b, thereby causing the partition plate 3 9 5a moves in the left-right direction, thereby adjusting the internal passage section of the upper portion of the induction portion 394 from -15 to 201210463. By tightening the nuts 393b, 393b by the operator, the partition plate 395a can be fixed to the rear side of the accommodating portion 3 93 at a desired position. With this configuration, the cross section of the passage closer to the downstream side than the upstream side of the inducing portion 3 94 is increased, and the seed ball G is easily supplied to the supply tank 191. As shown in Figs. 1, 2, and 5, the power transmission mechanism transmits the driving force of the engine 131 to the traveling portion 14 and the planting portion 17. In the present embodiment, the power transmission mechanism is constituted by a belt and a pulley, a chain and a sprocket, a transmission shaft, a gear, a gearbox 141, and the like, but other components may be used. The driving force from the engine 131 can be transmitted to the transmission case 141 by a pulley, a belt, and a transmission shaft belonging to the power transmission mechanism. The power transmitted to the transmission 141 is shifted in the transmission 141, and then transmitted to the traveling wheels 268 and 268 via the chain and the sprocket, whereby the crawlers 140 and 140 of the traveling portion 14 can be driven to travel. . Next, the transmission of the driving force to the planting portion 17 will be described using Fig. 1 and Figs. 5 to 7. The driving force from the engine 131 is transmitted to the planting input shaft 365 while shifting and changing the power transmission direction by a power transmission mechanism such as a transmission shaft, a gear, a pulley, and a belt (not shown) before the engine 131 ( Refer to Figure 5). The planting input shaft 3 65 is rotatably supported on the rear portion of the planting frame 18 on the left side of the planting portion 17 in front of the operation operation portion 15. -16- 201210463 The drive sprocket 40 of the first planting transmission mechanism 16a that transmits power to the push-out hand 4 (refer to Fig. 12) is fixed to the middle of the planting input shaft 365. On the other hand, the drive sprocket 30 of the second planting transmission mechanism 16b that transmits power to the ring body 3 is fixed to the left end of the planting input shaft 365. In other words, the power for planting the input shaft 365 can be simultaneously transmitted to the first planting transfer mechanism 16a and the second planting transfer mechanism 16b disposed in front of it. As shown in FIGS. 5 and 6, the first planting transmission mechanism 16a' is mainly driven by the drive sprocket 40, the follower sprocket 41, the tension sprocket 42, the push drive sprocket 43, the drive chain 44, and the push drive. The shaft 45 is formed. A drive sprocket 40 is fixed to the middle of the planting input shaft 365. Above the planting input shaft 365 (above the planting portion 17), an ejection drive shaft 45 which is slightly shorter than the left and right widths of the planting portion 17 is disposed. The drive shaft 45 is pushed out and rotatably supported to the left and right of the planting frame 18. At the left end of the drive shaft 45, a push drive sprocket 43 is secured. The follower sprocket 41 is disposed above the drive sprocket 40, and the tension sprocket 42 is disposed below the drive sprocket 43. In the drive sprocket 40, the follower sprocket 41, the tension sprocket 42, and the push drive sprocket 43, an annular drive chain 44 is wound. However, the follower sprocket 41 is engaged with the outer circumference of the drive chain 44, and the tension sprocket 42 is engaged with the inner circumference of the drive chain 44. Thus, the drive chain 44 maintains moderate tension and prevents sagging between the push drive sprocket 43 and the drive sprocket 40. Thus, power can be transmitted to the push drive shaft 45 from the planting input shaft 365 via the drive sprocket 40, the drive chain -17-201210463 44, and the push drive sprocket 43. Between the drive drive sprocket 43 and the push-out drive shaft 45, a clutch to be described later is disposed, and the transmission of power can be restricted by the action of the clutch. Then, the power transmitted to the drive shaft 45 is driven by the crank drive unit 5 to operate the push-out means 4 (see Fig. 3). The second planting transmission mechanism 16b is mainly driven by the drive sprocket 30, the rotating shaft 31, the follower sprocket 31a, the follower sprocket 31b, the tension sprocket 34, the annular body drive sprocket 32, and the annular body drive shaft. 33. The transmission chain 30a, 32a is constructed. At the left end of the planting input shaft 365, a drive sprocket 30 is secured. Below the planting input shaft 365 (below the rear portion of the planting portion 17), a rotating shaft 31 is disposed. The rotary shaft 31 is rotatably supported at both ends thereof to the planting frame 18 on the left side. On the right end of the rotary shaft 31, a follower sprocket 31a is fixed, and on the left end of the rotary shaft 31, a follower sprocket 3 lb is fastened. An annular drive chain 30a is wound around the drive sprocket 30 and the follower sprocket 31a. An annular body drive shaft 33 is disposed below the following sprocket 31a (above the planting position 17b). The annular body drive shaft 33 is rotatably supported by the left and right planting frames 18. At the left end of the annular body drive shaft 33, an annular body drive sprocket 32 is fixed. The lower end of the tension arm 34a is rotatably supported by the annular body drive shaft 3 3 on the right side of the annular body drive sprocket 3 2 . The rotating shaft 34b is fixed to the upper end of the tension arm 34a so as to protrude to the left. At the right end of the rotating shaft 34b, the tension sprocket 34 is rotatably supported. The following sprocket 31b, -18-201210463, the annular body drive sprocket 32 and the tension sprocket 34 are wound with an annular drive key. Article 32a. The tension arm 34a is configured to be biased by a spring (not shown) and to apply tension to the transmission chain 32a. Therefore, the power for planting the input shaft 365 can be transmitted to the rotating shaft 31 by the driving sprocket 30, the transmission chain 30a and the follower sprocket 31a, and then the power of the rotating shaft 31 can be passed through the follower sprocket. 31b, the transmission chain 3 2a, the tension sprocket 34, and the annular body drive sprocket 32 are transmitted to the annular body drive shaft 33. Further, as shown in Figs. 5 to 7, the annular body drive shaft 33 is attached to both inner sides of the main planting frame 181, and the inner annular body drive sprocket 3 5, 35 is fixed. The left and right annular body follower sprockets 36, 37, 38, and 39 are disposed so as to have a predetermined space formed in the side view. In the left and right annular body follower sprockets 36, 37, 38, and 39, an annular body 3 composed of an endless chain or the like is wound. Since the annular body 3 is arranged to be bilaterally symmetrical, the following description will mainly be made on the left side. Further, the planting position 17b is a position where the seed ball G is planted in the field, and is placed at the lowermost portion of the planting portion 17. The lower annular body follower sprocket 39 and the inner end of the inner annular body drive sprocket 35 at the rear thereof are arranged side by side in the front and rear horizontal directions as viewed from the side. Further, a guide member 174 is disposed at a lower portion of the planting portion 17, so that the ring body 3 wound around the ring-shaped follower sprocket 36' 37' 38' 39 can be rotated. The opening means 2 is kept moving substantially horizontally to the rear. The guide member 1 74 is configured to be guided by a roller 29 that holds the opening means 2 to be described later. -19- 201210463 In this way, the annular body 3 can be wound between the replenishing position 17a and the planting position 17b, and the opening means 2 is maintained, which is formed to be turned in the insertion direction in addition to the replenishing position 17a. It is configured to be rotationally driven in the direction of the direction. Therefore, the inner annular body drive sprocket 35 is disposed so as to be stretched and driven at the rear side of the planting position 17b, and the annular body 3 is rotationally driven. In other words, the annular body 3 of the planting position 17b is in a state of being stretched at the time of planting work, and is not slack, and can be traveled and synchronized with the crank drive unit 5 to be accurately planted. Then, the seed ball G holding the opening means 2 does not largely oscillate and is not shaken off, and can be reliably transported from the supply position 17a to the planting position 17b. The annular body 3 is formed of a chain or the like as described above, and is stretched so as to be polygonal (pentagon) in a side view of the planting frame 18. In detail, the annular body 3 is wound around an inner annular body drive sprocket 35 as a rotation support portion, and each annular body follower sprocket 36, 37, 38, 39, the inner annular body drive chain The pair of left and right wheels 35 are respectively disposed on the left and right inner sides of the planting frame 18 so as to be viewed from the top side in a polygonal shape as viewed from the side. Between the left and right annular bodies 3, the means for maintaining the opening 2 is transversely arranged in the left-right direction at a predetermined interval in the direction of rotation of the annular body 3. Then, as shown in Fig. 2 and Fig. 5 to Fig. 7, the replenishing position 17a is arranged to be inclined at a predetermined angle from the front height to the rear, and the seed ball G can be easily moved before the operation operation portion 15 is moved. Keep the opening means 2 replenish (insert). That is, the upper annular body follower sprocket 37 is disposed at the uppermost portion of the center portion before and after the planting portion 17. The height of the upper ring-shaped follower sprocket 37 is lower than the height of the eye, and is higher than the knee height, and the height of the shoulder is formed in order to ensure the front view. degree. The height of the rear annular follower sprocket 36 disposed below the upper annular body follower sprocket 37 is higher than the pedal 12a and lower than the operator's chest, and forms the seat of the seat 151. The degree of height of the face. Thus, the annular body 3 stretched between the upper annular body follower sprocket 37 and the inner annular body drive sprocket 35 is inclined so as to be high in front and then lowered, and the supply position 17a is disposed. The replenishment position 17a is placed in front of the seat 151 and is disposed in a range reachable by the hand of the operator seated on the seat 151. The replenishment position 1 7a, in detail, is disposed between the upper annular body follower sprocket 37 and the rear annular follower sprocket 36 so that the annular body 3 is inclined at a predetermined angle to be front high and low. ^ - The inner annular body drive sprocket 35 is disposed on the planting frame 18 while maintaining the angle so as to keep the opening means 2 moving obliquely forward and upward. That is, below the annular body 3 between the upper annular body follower sprocket 37 and the rear annular follower sprocket 36, a plate-like guide that defines the front-rear direction as the longitudinal direction is disposed. Lead member 173. The guiding member 173 is fixed to the planting frame 18 so as to be parallel to the annular body 3. The guiding member 173 is provided so as to be able to be disposed on the both sides of the holding opening means 2, and the roller 29, which will be described later, is rotated and guided by the seed ball insertion surface of the seed ball holder 2 1 toward the operator side. It is formed by moving forward and upward. At the replenishment position of 1 7 a, the holding perforating means 2 of the plurality of rows (three rows in the present embodiment) are arranged in parallel, and how much margin is provided in the replenishment time of the seed ball G, even if the supply is missed The timing can also be easily corrected. In this way, the operator can work by feeding the seed ball G to the holding hole opening means 2 to be described later while holding the seat 151, and the fatigue can be reduced and the work efficiency can be improved. . In the above-described annular body drive sprocket 32, the planting interval (sapling) P of the seed ball G can be changed by changing the diameter (number of teeth). In other words, if the diameter of the annular body drive sprocket 32 becomes larger (the number of teeth increases), the planting interval P becomes longer, and if the diameter becomes smaller (the number of teeth becomes smaller), the planting interval P becomes shorter. The operator can select the desired planting interval P by changing the annular body drive sprocket 3 2 . However, it is also possible to form a shifting mechanism in which the ring-shaped driving sprocket 32 is provided with a segment or a segment. Further, in this case, it is preferable that the shifting mechanism having one or no stages can be easily operated by a lever or the like. Next, the planting portion 17 driven by the power transmission mechanism described above is used to explain that the planting portion 17 is placed in front of the planting machine 1 in order to plant the seed ball G in the field. The planting portion 17 in the present embodiment is mainly configured by the planting frame 18, the holding opening means 2 disposed inside the planting frame 18, and the respective planting means such as the pushing means 4, etc. The configuration of each planting device of the planting portion 17 in the planting frame 18 will be described. Each planting device of the planting portion 17 is mainly constituted by a holding opening means 2, a pushing means 4, and the like which are disposed on the annular body 3. As shown in Fig. 1 and Fig. 7 to Fig. 12, the opening means 2 is held to hold the seed ball G while the seed ball G reaches the planting position 17b, and the hole is opened on the cover paper 1 means. In the present embodiment, the holding means -22-201210463 is regarded as a holding opening means 2 having an opening means for forming an opening portion in the cover paper 10. However, if the opening means is provided or the opening is provided in the cover paper in advance, the holding means may be provided as long as it has a function of transporting the seed ball G to the planting position 17b. The opening means 2 is mainly constituted by the casing 23, the plurality of seed ball holders 21 and the opening body 26. The casing 23 is a box-shaped structure in which the left and right directions are regarded as long sides and can be vertically divided. In the upper and lower sides of the casing 23, a plurality of upper and lower openings 23a are formed in a plurality of upper and lower portions (four in the upper and lower portions in the present embodiment). The insertion and discharge of the seed ball G can be performed. On the lower side of the opening portion 23a above the casing 23, a seed ball holder 21 having an insertion hole for the seed ball G and holding the seed ball G is fixed. Further, the aperture body 26 is disposed on the casing 23 below the seed ball holder 21. The seed ball holder 21 has a plurality of rectangular holding plates (a first holding plate 211, a second holding plate 212, and a third holding plate 213) and a plurality of rectangular opening plates 214. The seed ball holder 21 is formed by aligning the center and the direction and adhering the holding plate and the opening plate 214 one by one in an alternating manner. In detail, the seed ball holder 21 is a first holding plate 2 1 1 , an opening plate 2 1 4 , a second holding plate 2 1 2 'opening plate 2 1 4 , and a third holding plate 2 from the top. 1 3, the order of the perforated plate 2 1 4 and the first holding plate 2 1 1 coincide. The perforated plate 2 14 is composed of an elastomer plate such as urethane, and has a diameter substantially larger than the seed ball G and can pass through the size of the seed ball G of -23-201210463. Opening portion 214a. At the four corners of the perforated plate 214, the bolt holes 2 1 4b are opened, and the bolts can be inserted into the bolt holes 2 1 4b. The holding body (the first holding plate 211, the second holding plate 212, and the third holding plate 213) is made of an elastic plate such as rubber. In the first holding plate 211, a first insertion hole 211a having a smaller diameter than the seed ball G is formed substantially at the center thereof. In the second holding plate 212, a second insertion hole 212a having a smaller diameter than the seed ball G and larger than the first insertion hole 211a of the first holding plate 211 is formed substantially at the center thereof. The third holding plate 213 is formed substantially the same as the opening portion 214a of the opening plate 214 or has a smaller diameter than the opening portion 21a and is larger than the second insertion hole 212a of the second holding plate 212. A large third insertion hole 213a. In other words, the diameters of the respective insertion holes 211a, 212a, 213a become larger in the order of the first insertion hole 211a, the second insertion hole 22a, and the third insertion hole 213a. Therefore, the holding body is formed larger than the opening of the holding plate which is closer to the intermediate layer by the upper and lower outermost layers formed by the first holding plates 211 and 211 disposed on the upper and lower sides, and will be larger than the second. The second insertion hole 212a of the holding plate 212 is further formed closer to the opening area of the third insertion hole 213a of the third holding plate 213 of the lower side thereof. In each of the holding bodies 211, 212, and 213, a plurality of slits 211b, 212b, and 213b are radially formed from the respective insertion holes 211a, 212a, and 213a in the radial direction. More specifically, cracks 211b, 212b, and 213b are formed in the apex direction of the polygonal retaining body 73 which will be described later. A holding portion (a first holding portion 211d, a second holding portion 212d, and a third holding portion 21d) is formed between the slits 211b, 212b, and 213b and the slits 211b, 212b, and 213b, respectively. -24- 201210463 These slits 21 lb, 212b, and 213b are formed at equal angles in the circumferential direction and six in the radial direction with respect to the respective insertion holes 211a, 212a, and 213a. All of the holding plates 211, 212, and 213 are disposed such that the number and direction of the respective slits 211b, 212b, and 213b coincide with each other. Further, the holding plates 2 1 1 , 2 1 2, and 2 1 3 are formed in a state in which they are attached to the perforated plate 2 1 4 so as to be aligned with the bolt holes 2 1 4b in plan view, and a bolt 孑L is formed. 21 lc, 212c, 213c·. ·. By doing so, As shown in Figure 1 (a), Seed ball G, The system is first inserted into the first insertion hole 211a, And the first holding portion 211d near the first insertion hole 211a is pushed down. As shown in Figure 10(b), The seed ball G' can be guided to the second holding portion 212d by the first holding portion 211d. Further, as shown in Figure 11 (a), the seed ball G, The first holding portion 211d and the second holding portion 212d which are adjacent to the first insertion hole 211a and the second insertion hole 21 2a are pushed down. As shown in Figure 11 (b), The seed ball G' is guided to the holding plate 213. then, The outermost portion of the seed ball G' comes into contact with the third holding portion 213d to stabilize the posture. Further, the lower portion of the seed ball G' abuts on the upper surface of the first holding portion 211d disposed at the lowermost portion. here, Third holding portion 213d, It is at a level that is substantially in contact with the seed ball G. thus, An operator who inserts the seed ball G into the seed ball holder 21, The first holding portion 211d that can be held or placed at the lowermost portion by easily inserting the seed ball G to the extent that a small resistance is felt by the seed ball G and the respective holding portions 211d, 212d, The retention of 213d contact, The operator can insert a feeling to confirm that the seed ball G has reached a holding space that can be maintained in a stable state. -25- 201210463 by increasing the size of the insertion hole in the upper middle of the seed ball holder 2 1 It can be easily inserted and ensures (small resistance) moderate retention. This makes it easy to grasp the position of the seed ball G. And the seed ball G is uniformly inserted into the seed ball holder. And, The seed ball G can be inserted under the seed ball holder 21 by There is no holding portion that abuts the end of the seed ball G, Thus, the operator can further insert by inserting the seed ball holder 21 downward. The seed ball is placed on the first holding portion 2 1 1 d disposed at the lowermost position. in other words, Operators, It is possible to confirm by feeling whether the seed ball can be inserted into a predetermined position. thus, The seed ball G can be planted in the field in an appropriate posture. Keeping the opening means 2, The system has: Holding plate 211, 212, 213, It is formed with an insertion hole 211a in the center, 212a, 213a and from the insertion hole 211a, 212a, 213a is formed with a crack 211b toward the apex direction of the polygon corresponding to the holding body 73, 212b, 213b; And an aperture plate 214, It is formed in the center with an opening portion 214a larger than the seed ball G described above, And inserting the insertion hole 211a, 212a, 213a coincides with the center of the opening portion 214a and alternately overlaps the plurality of holding plates 211, 212, 213 and the aperture plate 214 are formed, And the holding plate 212 disposed at the center in the vertical direction, Insertion of 213 hole 2 1 2a, 2 1 3 a, The structure is larger than the insertion hole 21 la of the holding plate 2 1 1 disposed on the upper and lower sides * due to the apex of the holding body 73 and the holding plate 211, 212, 213 crack 211b, 212b, 213b—To, Therefore, the seed ball G can be held in an appropriate posture and planted surely. in other words, The seed ball G system is roughly triangular in plan view. And the apex of the seed ball G can cooperate with the crack 211b -26- 201210463 of the holding plate 211, 212b, Keep it 213b. thus, When pushed out of the guiding member (holding body 73) of the pushing means 4, The state of the hold does not change and can be held by the holder 73. result, The direction of the bud of the seed ball G (G1 at the germination) does not shift or fall when it is pushed out. It can be reliably maintained and planted. also, a holding plate 212 of the intermediate layer in the up-and-down direction, 213 insertion hole 212a, 21 3a forms an insertion hole 21 la than the upper and lower sides, 21 la is still bigger. Therefore, The seed ball G and the holding plate 211 can be alleviated as compared with the formation of the same size of the insertion hole. 212, Excessive friction caused by 213, And by holding the board 211, 212, 213 insertion hole 211a, 212a, The seed ball G is moderately maintained on the inner surface of 213a. Therefore, when the operator inserts the seed ball G into the holding means 2, no large friction is generated. It can be easily inserted without injuring the seed ball. And, The seed ball G can be held in a posture suitable for maintaining the opening means 2, The seed ball G can be planted in the field in an appropriate posture by means of the pushing means 4. In the holding plate 211 disposed on the upper and lower sides, a retaining plate 212 of the intermediate layer disposed between 211, 213 insertion hole 212a, 213a, The closer to the lower side, the larger the formation. Due to the retaining plate 212 of the intermediate layer, 213 insertion hole 212a, 213a, The opening area on the lower side (discharge side) is larger than the opening area on the upper side (insertion side). Therefore, the internal space can be made larger as it approaches the lower side. therefore, When the operator inserts the seed ball G, The front face of the retaining plate near the lowermost side will be in the retaining plate 212, The new resistance caused by 213 has become Or after being lightened, The new resistance -27-201210463 force is felt again due to the lowermost holding plate 2 1 1 . thus, It is easier for the operator to grasp the insertion position of the seed ball G in the holding opening means 2. then, Since the seed ball G can be mainly supported by the holding plates 211 disposed on the upper and lower sides, The 211 is easily inserted into the holding opening means 2 with an appropriate posture while maintaining a proper posture. Therefore, it can be planted in the field in an appropriate posture by means of the introduction means 4. As shown in Figure 2 and Figure 7 to Figure 2, Opening body 26, The four plates are bent into a side view and viewed in an inverted L shape. One side is rotatably disposed on the opening and closing drive unit 24. On the other side, The system protrudes downwards, And the front end of the other side can be easily spurted to cover the paper 1 〇 and form an opening portion, And formed a pointed shape. An opening and closing driver 24 for opening and closing the driving opening body 26, It is constructed by a link mechanism, And disposed between the seed ball holder 21 and the aperture body 26. On both sides of the opening and closing drive unit 24, The drive arm 25 is rotatably coupled. The outer end of the driving arm 25 is pushed to the inner side, Thereby, the opening body 26 is opened. also, A cam body (not shown) is provided in the front-rear direction on the side of the driving arm 25 on the inner side of the lower portion of the planting frame 18. The cam body ' is formed to protrude toward the inner side, 抵 abutting the outer end of the driving arm 25, And because the outer end of the driving arm 25 abuts and rotates, Thereby, the opening body 26 forms an opening portion in the cover paper 10. in other words, In a state where the outer end of the driving arm 25 abuts against the cam body, The front end portion of the opening body 26 is located around the opening portion 23a' and the opening body 26 is opened. In the state where the driving arm 25 does not abut against the cam body and the driving arm 25 protrudes toward the outside of the casing 23, the front end of the opening body 26 is -28 - 201210463, Is located at the center of the opening portion 23a.

First of all, By using the pattern to keep the opening motion of the opening means 2 and the pushing means 4, the opening means 2 is maintained. When planting operations, As shown in Figure 22 (a), By rotating the annular body 3, The holding means 2 is moved from the front to the rear in the planting position 17b. at this time, By means of the synchronization guide bar 85 of the guiding portion 8, The lower end of the 85 abuts against the mounting plate 28 of the retaining means 2, The lateral guide plate 81 to which the lateral guide plate 81 is fixed is moved rearward. then, As shown in Figure 22(b), a guide shaft 84 protruding laterally from the lateral guide plate 81, 84. 84. 84, Is along the opening 80a of the side guide plate 80, 80a, 80a, The horizontal part of 8 0a, in other words, Guided and moved while sliding sideways. When the opening means 2 is moved further rearward, As shown in Figure 22 (c), The guide shaft 84 moves rearward along the inclined portion of the opening portion 80a. By moving upward after the opening means 2 (lateral guiding plate 8 1 ), Synchronous guide bar 85', 85 will be lifted up, And synchronizing the guide rod 85, The lower end of 85 will move more than the mounting plate 28 that maintains the opening means 2 -43- 201210463 When the synchronization guide 85, 85 and when the abutment of the opening means 2 is eliminated, By the elastic pressure in the direction toward the tensile member 86, The lateral guide 81 can be returned to the front. in other words, Each of the guide shafts 84 is movable to the front end of each of the opening portions 80a. And the synchronous guiding rod 85, The lower end of 85 is capable of abutting against the mounting plate 28 of the next retaining opening means 2 located in front. In the lateral guiding plate 81, The lower end of the duct 71 is slidably supported. therefore, The duct 71 is also moved in conjunction with the action of the lateral guide plate 81. Catheter 7 1, The rod support body 63 is slidably supported by the swing portion 6 disposed above the lateral guide plate 81. Since the swinging portion 6 is rotatably supported around the pivot point 60, Therefore, the duct 7 1 moves in the front-rear direction centering on the pivot point 60. thus, The planting push-out portion 7 held by the lateral guiding plate 81, It is possible to move (swing) synchronously at the planting position 17b with respect to the movement behind the holding opening means 2 as shown in Fig. 12, And when planting, The lower portion of the planting and pushing portion 70 can be surely inserted into the opening portion 23a of the holding opening means 2. Secondly, The operation of the means 4 for introducing the seed ball G to the field using the drawings will be described. As shown in Figure 6, Figure 7, Figure 13 and Figure 14, When the opening means 2 is held at the predetermined position of the planting position 17b, it abuts against the contact of the stopper switch and becomes ON. then, The electromagnetic solenoid 50 connected to the limit switch will operate, Further, the engaging lever 51 is rotated to be detached from the engaging body 52. in this way, The engaging body 52 is engaged with the push drive shaft 45 to integrally rotate. And power can be transmitted to the push drive shaft 45. thus, The push drive on the left side -44- 201210463 The rotational force of the sprocket 43 Can be transferred to the push drive shaft 45, And as shown in Figure 14, The rotating arm 53 fixed to the left and right of the push-out drive shaft 45 is rotated. In addition, The aforementioned limit opening relationship can be turned OFF (opened) after passing through the abutting portion, And the electromagnetic solenoid 50 will return to its original position. then, When the engaging body 52 performs a rotation, Will engage with the engagement lever 51 again, The power transmission from the engaging body 52 to the push drive shaft 45 is broken. When the push drive shaft 45 performs a rotation, The rotating arm 53 connected thereto also performs a rotation. And the follower arm 54 is moved forward and backward while moving forward and backward. Thus, the upper rod support body 56 can be interlocked from the follower arm 5 4 through the joint arm 55 and moved upward and downward. On the upper rod support 56, The planting and launching body 70 is installed with the planting and pushing portion 7, 70. 70. Above 70. therefore, The planting body 70 can be moved up and down in conjunction with the movement of the upper and lower support bodies 56. And, On the upper rod support 56, Passing through a pair of left and right sliding bodies 57, It is disposed so as to be slidable to the swing link 62. therefore, Planting the body 70, The linkage with the movement of the swinging portion 6 in the front and rear directions, And moving in the front-rear direction with the rotation fulcrum axis 60 as the center. And no reluctantly moving up and down. in other words, By the action of the crank drive unit 5, The planting and pushing unit 7 moves up and down. also, When the action of the crank drive unit 5 is performed, When the planting and pushing unit 7 is moved to the lower side (refer to Fig. 14(c)), the seed ball G can be planted in the field. The action of planting the planting body 70 will be described. Moving downward by the upper rod support 56 of the crank drive unit 5, Planting -45- 201210463 The launching section 7 will move downwards. therefore, As shown in Figure 19, The upper engaging body 90 and the restricting member 96 fixed to the upper rod support 56, Will be as shown in Figure 23, Both are adjacent to the second lower engaging member 2 94 of the lower engaging body 2 90, The collar 94c of the upper engaging body 90, The inclined side 2 9 4 a of the second lower engaging member 294 is brought into contact. And, Moving upward by the upper engaging body 90, The collar 94c pushes the second lower engaging member 294 along the inclined side 294a. thus, Lower snap member (293, 294), The spring pressure against the third biasing member 296 (refer to Fig. 23) is reversed and the direction of the arrow C is rotated about the pivot point 295. at this time, Since the front portion of the upper engaging member 94 is in contact with the restricting projection 92a, 93b, Therefore, the front yoke 9a is not rotated about the rotation fulcrum shaft 94a, and the collar 9k pushes the second lower engaging member 294. also, Since the second lower engaging member 294 is pushed, Therefore, the third biasing member 296 is compressed in a substantially upward and downward direction. Further, the upper end of the long hole 297a of the insertion plate 297 is moved in contact with the locking shaft 292b. And, When the collar 94c reaches the lower side of the inclined side 294a, Lower snap member (293, 294), The elastic pressure above and below the third elastic member 296 can be The rotation fulcrum shaft 29 5 is rotated in the D direction. At this time, the body 70 and the upper engaging body 90 are planted. The department is the lowest. on the other hand, at this time, As shown in Figure 22, Keep the opening means 2, The outer end of the driving arm 25 can be abutted by the cam body disposed at the planting position 17b. And rotating by the opening body 26 toward the outside, On the other hand, the covering paper covered in the field forms an opening portion. after that, As shown in Figures 25 and 26, The holder 73 disposed at the lower end of the catheter 71 is disposed in the lower movement -46-201210463, Will invade from the top to keep the opening 2, And the seed ball G held by the seed ball holder 21 is held. Holding body 73, Keep the seed ball G while keeping The lower side moves simultaneously with the seed ball G. The holder 73 of the catheter 71 is attached to its lowermost position, The seed ball G is pressed against the field below the opening portion of the cover paper 10 (refer to Fig. 2). after that, The movement of the crank drive unit 5 above the upper rod support 56 (refer to Fig. 14(d)), The planting and pushing portion 7 moves upward. on the other hand, Engagement 9, As shown in Figures 24 and 27, Since the collar 94c is locked to the lower engaging member (293, 294), So as the upper rod support 56 rises, Among the engaging portions 9, Only the restricting member 96 fixed to the upper rod support 56 rises. but, The upper engaging body 90 other than the restricting member 96, It will stop rising until the connecting shaft 91 is in contact with the lower end of the long hole 96a. By the rise of the upper rod support 56, The duct 71 fixed to the upper rod support 56 through the mounting member 76 rises. at this time, Upper rod support 56, Resisting the elastic force of the first elastic member 75, And compressing the first elastic member 75 through the mounting member 76 and the receiving member 77a. On the other hand, the planting rod 72 fixed to the sliding member 77 while shortening between the mounting member 76 and the sliding member 77 lifts only the guide tube 71 at a position where the original state is maintained. on the other hand, at this time, When focusing on the lower end of the planting introduction portion 7 shown in Fig. 17, The planting rod 72 can maintain its height by being restrained by the connecting shaft 9 1 . And connected to the holder 73 of the catheter 71, After rising to a predetermined height, The planting rod 72 will rise. thus, The planting rod 72 will press the seed ball G above -47- 201210463, Only the conduit 71 and the retaining body 73 will move upwards. Seeds of the field, ball G, Can be released from the holding state of the holding body 73, And planted in the field. And, After just planting, Even if foreign matter such as mud adheres to the holding body 73, It will also rise later because the planting rod 72 is later than the tube 71 and the holding body 73. The planting rod 72 can be used to push the soil in the holding body 73 downward. then, As the conduit 71 rises, the first moldboard 74a removes the attachment of the planting rod 72 that stays underneath it. Further, the deposits not removed by the first moldboard 74a can be removed by the second mold blade 74b. also, The adhering matter removed by the second moldboard 74b is dropped from the opening of the first moldboard 74a. And, By moving over the upper rod support 56 of the crank drive unit 5 shown in FIGS. 14(c) and (d), As shown in Figure 28, The sliding member 77 pushes the contact member 91a upward. Further, the lower end of the long hole 96a of the restricting member 96 pushes the connecting shaft 91 upward. With the two pushes, The upper engaging body 90 will rise. also, Since the collar 94c is locked to the second lower engaging member 294, Therefore, the rotation fulcrum shaft 94a rises due to the elastic pressure against the second elastic member 95. The upper engaging member 94 is rotated downward about the pivot point shaft 94a. ' by the rise of the upper upper engaging member 94, The collar 94c is raised while rotating on the outer circumference of the abutting shaft 94b. The engagement with the second lower engaging member 294 can be eliminated. Upper engaging member 94, As shown in Figure 19, It will return to the original position by the elastic pressure of the second biasing member 95. The same 'first elastic member 75, By its elastic pressure, And pushing the contact member 91a upward through the -48-201210463 sliding member 77, Further, the upper engaging body 90 other than the restricting member 96 is raised. thus, The rotation fulcrum shaft 94a abuts against the upper end of the long hole 96a of the restriction member 96. at this time, The planting rod 72 will move upwardly from the duct 71 as shown in Figs. 12 and 13. then, With the aforementioned guiding portion 8, The duct 71 is returned to the front centering on the pivot point 60. The conduit 71 will be located above the new retaining opening means 2 holding the seed ball G. thus, Planting and launching department 7, The planting and pushing portion 7 is moved up and down by the crank drive unit 5 moving up and down. Further, the swinging portion 6 and the guide portion 8 move in synchronization with the holding opening means 2 in the front-rear direction. The planting and pushing portion 7 can plant the seed ball G held by the holding opening means 2 to the field. The seed ball G can be planted in the field by performing the aforementioned series of actions for each of the holding opening means 2. This series of actions, For the second planting and pushing body 70 of the left and right center of the body where the engaging portion 9 is not provided, 70, The connecting shaft 91 and the left and right center contact members 91a of the engaging portion 9 are passed through, 91a is coming. in other words, And the planting body 70 disposed on the left and right sides, 70 planting rod 72, 72 is roughly the same, Two planting rods 72 in the center of the left and right sides of the body, 72, The action is actuated as the connecting shaft 9 1 moves up and down. By doing so, Compared to planting rods 72, 72. 72. 72—the body is connected to the connecting shaft 9 It also reduces planting losses. And more efficient planting operations. the following, The movement from the holding of the seed ball G held by the opening means 2 to the holding body 73 and the holding state of the seed ball G of the holding body 73 are explained in the description of -49-201210463. As shown in Figures 18 and 25, for example, The seed ball G is the seed ball of the garlic, Seed ball G, When the root side is regarded as the lower side, it is roughly a second-order triangular shape in a plan view. The portion corresponding to the bottom side of the equilateral triangle extends in a direction orthogonal to the planting traveling direction (arrow A), Planting the seed ball G' will allow the leaves to grow in the same direction. And the leaves can expand efficiently, It can even increase the amount of garlic harvested. therefore, Operators, When the seed ball G is inserted into the seed ball holder 21 that holds the opening means 2, The germination point G1 that becomes the apex turns to the front upper side, And at the time of harvesting, the contact portion G2 which is connected to the garlic stalk of the other seed ball G The G2 is inserted into the seed ball holder 21 in a manner of turning obliquely forward. In addition, at this time , The seed ball holder 21 is inserted as long as the directions of the apexes of the seed balls G are aligned. Can also be in the opposite direction, Insert the seed ball holder 2 1 to the right or left and hold it. The seed ball G held by the opening means 2 in the aforementioned state, Is in the planting position 17b (refer to Figure 7), By holding the retaining body 73 of the pusher 70, it is maintained, Instead of maintaining the opening means 2, And move down. In detail, As shown in Figures 25 and 26, Holding the lower end of the body 73, After invading the means for maintaining the opening 2, Will abut against the holding portion 21h of the upper portion of the seed ball holder 21, And move down, Further, the holding portion 21 h of the seed ball holder 21 abutting on the seed ball G is pushed downward. in other words, Seed ball G, The holding state depending on the seed ball holder 21 is gradually released from the upper portion thereof as it moves toward the lower side of the holding body 73. And contacting the contact portion 73b, By changing the posture, the body 73 can be maintained to protect the -50-201210463, To replace the seed ball to hold 21° at this time, As shown in Fig. 18, the holding member 7 3 ' is in a plan view, and the two apexes of the side surface and the rear portion near the germination portion G1 of the seed ball G are abutted against the side surface portion 73d. The seed ball G is held by the contact portion 73b. When the holder 73 holds the seed ball G by the contact portion 73b, it has a shape depending on the seed ball G. And the side surface sandwiched by the two vertices abuts on the side surface portion 73d, Or the case where the two vertices abut against the corner portion 73 e, However, even at this time, the posture of the seed ball G can be maintained in a posture substantially the same as the posture held by the holding opening means 2. Seed ball G, In the side view, Germination at the G 1 side, More reduced shape than the root side. therefore, The three vertices of the seed ball G in a bird's eye view, The side surface portion 73d of the contact portion 73b in the holder 73 which is softly changed in shape is brought into contact with the line and the surface. in other words, Holding body 73, The line is contacted with the seed ball G by at least three lines or faces. thus, When the planting body 70 moves downward, The seed ball G-edge can be stably moved while moving. As mentioned above, The planting machine 1 of the present embodiment, It has a walking section. And a planting section 17 for planting seed balls, The planter that grows the seed ball G at each planting interval P (predetermined interval) while walking on the field while walking in the field. The aforementioned planting section 17, The system has: Keep the opening means 2 (holding means), It is used to hold the seed ball G; And the pushing means 4' is planted by pushing the seed ball G held by the holding means 2 to the field. The aforementioned means 4, The system has: a cylindrical conduit 7 1 (guide member), It moves the seed ball G held by the aforementioned maintaining opening means 2 - 51 - 201210463 to the field; And the planting rod 72' is attached to the duct 71 and the seed ball G moved by the duct 71 is pushed out to the field and planted. The aforementioned conduit 71, A holding body 73 for holding the seed ball G when the seed ball G is moved is provided, And the aforementioned holding body 73, a cylindrical shape with one side facing the opening of the holding opening means 2, The inner cross-sectional shape is formed into a polygonal shape. By doing so, When the seed ball G is planted in the field, Hold body 73, The pair of seed balls G are in contact with each other in the outer periphery. The seed ball G is held in an appropriate posture. thus, The seed ball G held by the holding body 73 is pushed out by the planting rod 72, By this, it is possible to plant the appropriate posture in the original state in the field. result, The posture of the seed ball G planted in the field is better. And the crops grow evenly. ‘The planter 1 of this embodiment, The holder 73 is made of a soft material. By doing so, It is possible to increase the contact area of the holding body 73 with the seed ball G, It is also easy to hold the seed ball G in the holding body 73 in an appropriate posture. thus, The seed ball G can be planted in the field in an appropriate posture. And, Since the holding body 73 is softly contacted with the outer peripheral surface of the seed ball G, the seed ball is not damaged. (Industrial Applicability) The present invention can be utilized in a technique of planting seed balls in a field planter. -52-201210463 [Brief Description of the Drawings] Fig. 1 is a rear perspective view showing the configuration of a planting machine according to an embodiment of the present invention.
