第1圖是本創作的一實施例的穀物聯合收割機的全體 左側面圖，第2圖是相同的全體平面圖，第3圖是脫榖部 與篩選部的左側面模式圖，第4圖是顯示脫粒室的正面圖 ，第5圖是顯示脫粒室下部的正面圖，第6圖是顯示承網 的展開圖，第7圖是承網的側面圖，第8圖是前側網緊壓 構件的後部立體圖。 首先，針對本創作的穀物聯合收割機的全體構造，用 第1圖、第2圖來加以說明。 在鏈軌式行駛裝置1上載置有機體框架2，在該機體 框架2前端是可升降地配設有扶禾、收割部3。該扶禾、 收割部3，在前端是突出有撥草板4來將榖稈進行撥分， 在其後部立起設置有牽引盒體5,藉由從該牽引盒體5突 -8 - M287574 ’ (5) « 出的耙齒6的旋轉來牽引榖稈，用配設在上述撥草板4後 部的割刀7來收割榖稈的根部。 所收割的榖稈，會以上部搬運裝置、下部搬運裝置、 縱搬運裝置8將其朝後部搬運，根部側會從該縱搬運裝置 8的上端接替到餵送鏈9，將榖桿搬運到脫榖部20內。在 從該餵送鏈9後端起的斜後方配設有排稿草搬運鏈1 〇， 在該排稿草搬運鏈1 0後部下方配置有以排稿草切割裝置 B 、擴散運輸機等所構成的排稿草處理部1 1，在將排稿草 切斷成爲稿草片之後，會一邊使其擴散一邊均勻地放出到 田間，或者不切斷就將其排出。 在上述脫榖部20的側部配設有用來儲存篩選後的精 製榖粒的糧箱1 3，在該糧箱1 3前部配設有運轉室1 4。另 一方面，在糧箱1 3後部立起設置有排出螺旋鑽1 5的縱螺 旋鑽15a，以該縱螺旋鑽15a爲中心讓排出螺旋鑽15及 糧箱1 3可轉動，藉由將糧箱1 3朝側邊轉動則能容易地對 I 主機內部側所配置的驅動系統或油壓系統進行維修。 在該糧箱1 3的底部是朝前後方向配設有排出輸送機 1 6，是將該排出輸送機1 6的後部與縱螺旋鑽1 5 a的下部 連通，並且從該排出輸送機1 6的後部將動力傳達到上述 排出螺旋鑽1 5，從排出螺旋鑽1 5前端將糧箱1 3內的榖 粒排出到卡車等。並且，在脫榖部20的下方，配設篩選 部3 0，來將從脫榖部20落下的榖粒或稿草屑等進行篩選 ，將精製榖粒輸送到上述糧箱1 3，將稿屑等排出到機外 -9- M287574 • (6) 接下來，用第3圖來說明脫榖裝置的脫榖部20。 在形成於脫榖部20的脫粒室2 1，是設置有軸支架 機體的前後方向的略圓柱形狀的脫粒滾筒22，在該脫 滾筒2 2的外周面植設有脫粒齒2 2 a、2 2 a......。且可裝 地包圍設置著半圓形狀的承網23以覆蓋該脫粒滾筒22 下部周邊。另一方面，藉由餵送鏈9，會一邊限制榖稈 根部側，且將榖稈的前端側插入到脫粒滾筒22的下方 ® 將榖稈運送到機體後方。此時，藉由脫粒滾筒22的旋 來進行脫粒，從承網23讓榖粒或稿草屑等漏下。 在從上述脫粒滾筒22的後部的側邊（糧箱1 3側， 本實施例中是在機體進行方向右側）起的後方，形成了 理室25，在該處理室25內，作成略圓柱形狀的送塵口 理滾筒26，是在脫粒滾筒22的後部的側邊，與脫粒滾 22平行，朝前後方向被橫架支承著。而在覆蓋脫粒滾 22且形成脫粒室2 1的脫粒滾筒盒體的後部（右）側面 胃以及覆蓋送塵口處理滾筒26來形成處理室25的處理滾 盒體的前部（左）側面，開設有送塵口 27，讓脫粒室 與處理室25連通在一起。而且包圍設置有半圓形狀的 理滾筒網28，以覆蓋該送塵口處理滾筒26的下部周邊 而在脫粒滾筒22無法處理的附有枝梗的榖粒等的未處 物，會從送塵口 27被運送到處理室25內加以處理，只 通過在上述處理滾筒2 8所設置的孔部（網眼）的處理 才會落下。 在上述處理滾筒網2 8的下方，是朝前後方向軸支 在 粒 卸 的 的 而 轉 在 處 處 筒 筒 筒 21 處 〇 理 有 物 架 -10- M287574 (7) 有送塵搬運輸送機29。送塵搬運輸送機29是螺旋式的輸 送機，藉由該送塵搬運輸送機29，可以通過在處理滾筒 網2 8所設置的孔部（網孔）而漏下的處理物’會被朝向 機體前方（也就是與送塵口處理滾筒26的搬運方向相反 )搬運，從設置在送塵搬運輸送機29前端的排塵口 29a 再被投入到篩選部3 0。 接著，針對脫榖裝置的篩選部3 0 ’用第3圖加以說 •明。 針對篩選部3 0，是利用搖動篩選裝置31的搖動篩選 與風選機32來進行風力篩選，而分級成第一糧物、第二 糧物、與稿草屑等。 搖動篩選裝置31是收容在機框33內。搖動篩選裝置 31的前後長度是決定爲：其前端部是延長到脫粒滾筒22 的前端部的下方，其後端部是延長到送塵口處理滾筒26 後端部的下方。在搖動篩選裝置31前下部是設置有沒有 ® 圖示的搖動軸，並且在後部設置有搖動驅動機構3 4，藉 由搖動驅動機構3 4讓搖動篩選裝置3 1對機框3 3擺動。 在搖動篩選裝置31的前部設置有前滑板3 5，並且在 該前滑板35的後下方設置有後滑板36。該前後的滑板35 、36是將板狀的構件形成爲波狀，通過承網23的處理物 (榖粒及稿草屑等的混合物）會落下到前後的滑板3 5、 36上’藉由搖動篩選裝置31的搖動而被朝向機體後方搬 運。而且’在上述前滑板3 5的後方設置有篩選裝置5 0， 並且在後滑板36後部連接設置有第二篩選部也就是網狀 -11 - M287574 (8) 的榖粒篩3 7，在榖粒篩3 7與上述後滑板3 6的上方，且 在篩選裝置的後方，是覆蓋安裝有第一篩選部也就是穎糠 篩3 8。在穎糠篩3 8的後方，是配設有逐稿器3 9。 上述穎糠篩3 8，會因應投入到搖動篩選裝置3 1的處 理物的量來調節其開度，榖粒及較細的稿草屑會通過穎糠 篩3 8落下到其下方，較穎糠篩3 8的開口更大的稿草屑則 會朝後方搬運。此時，在穎糠篩3 8與榖粒篩3 7之間會藉 B 由風選機32從篩選部30的前方向後方產生篩選風，較細 的稿草屑的一部分會朝後方被吹走而與榖粒分離。 在上述搖動篩選裝置3 1的前滑板3 5後部下方且在後 滑板36的前部下方配置了風選機32，是讓風選機對穎糠 ’篩38或榖粒篩37進行送風。並且，在第一輸送機41與 第二輸送機42之間也設置有負壓送風扇也就是第二風扇 43來進行篩選送風，即使是風選機32的篩選風力較弱的 篩選部30後部其篩選性能也不會降低。 B 在搖動篩選裝置3 1的後端部附近是在整個寬度都橫 設有吸引風扇40，而可將乘著從上述風選機32、第二風 扇43所供給的篩選風的流動的塵埃或脫榖時所產生的塵 埃等以該吸引風扇40加以吸引而排出到機外。 在上述搖動篩選裝置31下方的前後途中位置’在左 右方向橫設有第一輸送機41與第二輸送機42。第一輸送 機4 1與第二輸送機4 2的位置關係，第一輸送機41是在 接近風選機32側（機框33的前部），第二輸送機42是 在距離風選機3 2較遠側（機框3 3的後部）。 -12- M287574 (9) 在第一輸送機4 1的右端部是連結著設置成其長軸方 向（搬運方向）爲略上下方向的揚榖輸送機44’該揚榖 輸送機44的上端是與糧箱13內連通。 在該構造中，投入到篩選部3 0內，漏下到搖動篩選 裝置3 1的前滑板3 5上的榖粒、枝梗附著粒、未熟榖粒、 以及細稿草屑等的混合物，在漏下到穎糠篩3 8上的過程 ’利用以風選機3 2所產生的從篩選部3 0的前方朝向後方 的氣流，將細稿草屑朝向後方吹散。漏下到穎糠篩3 8上 的榖粒、枝梗附著粒、未熟榖粒、及細稿草屑等的混合物 ，藉由搖動篩選裝置3 1的搖動，會被朝後方搬運。此時 ’榖粒、枝梗附著粒、未熟榖粒、及細稿草屑等會從穎糠 篩3 8的開口部朝後方落下，較大的稿草屑會被搬運到穎 糠篩3 8後方，經過逐稿器3 9排出到機外。 從穎糠篩3 8的開口部落下的榖粒、枝梗附著粒、未 熟榖粒、及細稿草屑等會漏下到後滑板3 6及榖粒篩3 7上 。此時也會藉由來自於風選機3 2的篩選風，將細稿草屑 的一部分向後方吹散使其分離。 漏下到榖粒篩3 7上的榖粒、枝梗附著粒、未熟榖粒 、及細稿草屑等中，榖粒、未熟榖粒、細稿草屑等會於榖 粒篩3 7漏下而落下至下方。此時，重量較大的榖粒（第 一糧物），會被回收到第一糧物回收部4 6 (是設置在滑 板4 5的後方的篩選部3 0底面的凹部，收容著第一輸送機 4 1 )，從第一輸送機4 1經過揚榖輸送機4 4，被搬運到糧 箱13。 -13- (10) M287574 另一方面’重量較小的未熟榖粒、細稿草屑的一部分 、斷穗粒、或榖粒等所混合的未處理粒，會藉由來自於風 選機3 2的篩選風被吹到後方，被回收到第二糧物回收部 4 7 (是設置在第一糧物回收部4 5的後方的篩選部3 0底面 的凹部’收容著第二輸送機41)，從第二輸送機42經過 二次還原輸送機48，被搬運到枝梗處理滾筒49，藉由該 枝梗處理滾筒4 9除去枝梗之後，再將其投入到前滑板3 5 ^ 上（或穎糠篩3 8上）。 接著，針對脫榖部20的承網23的構造，用第4圖〜 第7圖來加以說明。 承網23，是將糧箱1 3側（進行方向右側）作爲內側 網6 0，將餵送鏈9側（進行方向右側）作爲前側網61， 分隔成搬運榖稈的穗前側與根部側，在送塵口 27起端的 前後方向的路線1 00，是以連結部65來連結內側網60與 前側網61。 ® 在上述連結部65，在形成在內側網60及前側網61 的周圍的各網框60a、61a中，在機體前後方向隔著略相 等的間隔的位置，是從其中一個網框60a (或61a)的抵 接部側朝向接線方向突出設置複數的銷栓62a、62a…… ’在另一方的網框6 1 a (或60a )的抵接部側形成有對應 於各銷栓62a所突出設置的位置的插入孔。藉由將前側網 61壓入到內側網60側，且將銷栓62a嵌合到插入孔，將 內側網60與前側網6 1連結起來構成承網23。設置上述 銷栓62a的位置或數量並不限定，其連結構造也沒有限定 -14- (11) M287574 ，也可以用使凹凸部嵌合的構造。 而在上述內側網6 0的網框部6 0 a的糧箱1 3側，是將 機體前後方向的位置作成與上述銷栓6 2 a大略相同，是朝 接線方向突出設置有複數的銷栓62b、62b……，藉由將 這些銷栓62b嵌合在具備於機體側的作爲固定構件的支架 6 6，來將內側網6 0固定在機體。另一方面，在上述前側 網6 1的網框部6 1 a的餵送鏈9側，是固定著設置於機體 B 主體側的托架7 1，將前側網6 1固定在機體。在脫粒滾筒 22下方將承網23固定在機體。 上述承網23是作成可以從機體側邊進行裝卸。也就 是說’是將作成可對機體側邊進行開閉的用來支承餵送鏈 9的餵送鏈框架8 1開放，是從機體側邊沿著設置在機體 側的框架67所設置的導軌，而可圓弧狀地拉出或插入而 可進行裝卸。承網23，如上述，是與脫粒滾筒22的軸芯 方向平行地在圓弧部分分割成複數個構造（本實施例中是 t 兩個）’讓承網23不會碰到餵送鏈9或脫榖外殼等而可 進行裝卸，容易進行對機體的裝卸作業。讓承網容易製造 ’且其保管場所也能節省空間。 如第6圖所示，上述承網23是藉由上述內側網60與 目11側網6 1而形成爲平面來看略L字型，上述前側網6 1與 內側網60相比，其前後方向較長且稍微朝後方突出。該 內側網60與前側網61，是在網框60a、61a上固定設置 有薄金屬製的板體63、64，在該板體63、64穿設有方形 的孔部73、74，是作成網眼狀。通過這些孔部73、74， -15- (12) M287574 藉由脫粒齒2 2 a、2 2 a......來讓脫落的處理物漏下到承網 2 3上。在本實施例，雖然孔部2 9 4 a的形狀爲方形，而有 可以是圓形或多角形。也可以代替在板體6 3、6 4構成孔 部7 3、7 4的方式，也可以用編織線材的網子來構成。 上述孔部7 3的大小（一個孔部的開口面積）是大於 孔部74的大小（一個孔部的開口面積）’從前面開始每 個預定區間，是以配置開口面積較大的孔部7 3的部分， ® 配置較小孔部74的部分，配置較大孔部73的部分的順序 ，來將孔部73、74設置在承網23。也就是說，在位於承 網2 3的具有前後寬度L 1的脫粒滾筒2 2的前部下方的部 分與位在具有前後寬度L2的脫粒滾筒22的後部下方的部 分，是設置有開口面積（網眼）較大的孔部7 3。另一方 面，在位於承網2 3的其他部分的具有前後寬度L3的脫粒 滾筒的前後中央部下方的部分，是設置有開口面積（網眼 )較小的孔部74。 ® 而上述承網23，如第7圖所示，配置開口面積較大 的孔部7 3的前後寬度L 1的部分，是位於前滑板3 5的上 方，配置開口面積較小的孔部74的前後寬度L2的部分， 是位於從前滑板3 5後部到篩選裝置5 〇的後部的上方，或 者位於從前滑板3 5的後部到後滑板3 6的上方，配置開口 面積較大的孔部7 3的前後寬度l 3的部分，是位在從篩選 裝置5 0的後部到穎糠篩3 8或榖粒篩3 7的前後中途部上 方。也就是，前後寬度L 3的部分，是位於脫粒室2 1的送 塵口 2 7的側邊。藉此，將承網2 3的開口面積較大的孔部 •16- (13) M287574 73配置在前滑板35的上方與送塵口 27附近，開口面積 較小的孔部74則是配置在前滑板35後部與篩選裝置50 的上方。 藉由這種構造，在位於脫粒滾筒22的前部下方的承 網23的前部分，由於是將承網23的孔部73作得較大， 讓脫粒滾筒22的處理物容易漏下到搖動篩選裝置3 1的起 端部的前滑板35上。即使大量搬運榖稈而脫粒滾筒22的 • 處理量很多也不容易產生堵塞的情形，能夠促進在承網 2 3前部的處理物的漏下，而能夠高效率地以前滑板3 5進 行篩選。 在位於脫粒滾筒22的前後中央部下方的承網23的前 後中央部分，是設置有承網23的開口面積較小的孔部74 ，處理物較難從孔部74漏下。因此，在脫粒後可利用脫 粒滾筒21的旋轉來充分地進行榖稈的搓揉，從前滑板3 5 經由篩選裝置5 0、穎糠篩3 8、後滑板3 6，來風選大量的 ® 榖粒，而只有精製榖粒落入到第一糧物運輸機41。另一 方面，由於承網23的開口面積較小的孔部74所漏下的處 理物的量較少，所以當從篩選裝置5 0落下時，可以防止 處理物集中而產生堵塞的現象。於是，可防止在承網2 3 前部的堵塞情形，可在搖動篩選裝置的起端部充分地進行 篩選處理。而以脫粒滾筒2 1充分脫粒處理的榖粒，容易 從配置有開口面積較大的孔部73的承網23的後部分漏下 ，精製榖粒會通過穎糠篩3 8、榖粒篩3 7而落下到第一運 輸機4 1，未熟榖粒、細稿草屑的一部分、斷穗粒、或榖 -17- (14) M287574 粒所混合的未處理粒，會藉由搖動而被送往後方，且同時 會藉由來自於風選機3 2的篩選風向後方吹散，被送往第 二糧物回收部。 在設置有孔部73、74的承網23的內側網60與前側 網6 1的上面部，是在脫粒滾筒2 2的旋轉方向配置有以金 屬製的板材所形成的預定高度的分隔板7 6、7 7。也就是 ’分隔板76、77 ’相對於機體進行方向是被配置在左右 ® 方向’是被設置成：與脫粒滾筒22的脫粒齒22a平行， 當脫粒齒2 2 a旋轉時是位在其間。在內側網6 0，在機體 前後方向隔著略相等的位置是平行地突出設置著分隔板 7 6，從內側網6 0與前側網6 1的抵接部延伸到糧箱1 3側 端部。 另一方面，在前側網61，除了前部分之外，在前後 中央部分與後部分隔著適當間隔的位置是突出設置有分隔 板77，是從前側網6 1與內側網60的抵接部延伸到餵送 ® 鏈9側端部。該分隔板7 7，是配設在承網2 3的前後寬度 L3的部分與前後寬度L2的部分，特別是L字型狀的承網 23的突出部23a ’在設置了開口面積較大的孔部73的前 後寬度L2的部分，相鄰的分隔板7 7、7 7之間的間隔是配 置成爲比前後寬度L3之間更狹窄的等間隔，而能讓脫榖 性能提昇。該突出部23a是餵送鏈9的榖稈搬運通路9a 的後半部，是位於脫粒滾筒2 1的後部下方。如果在成爲 前側網6 1的前部分的前後寬度L 1的部分設置分隔板77 的話，當能夠搬運大量的榖稈時，該分隔板7 7的存在反 -18- (15) M287574 而會對榖稈的搬運及脫粒作用造成妨礙’所以並不將分隔 板7 7配置在前側網6 1的前部。 藉此，在分別突出設置著上述分隔板76、77的內側 網6 0與前側網6 1，在前側網6 1的則部分沒有配置分隔 板77，所以不會使從扶禾、收割部3所搬運的榖稈在脫 榖部20的入口附近停滯，而能順暢地在脫粒室2 1內搬運 且藉由脫粒齒進行脫粒，而能夠防止在脫榖的入口附近產 • 生堵塞。藉由餵送鏈9所搬運的榖稈’會藉由配置在承網 23的後部的上述分隔板76、77而朝上方浮起，且同時會 藉由脫粒齒 22a、22a被向下壓。因此，能夠使脫粒齒 22a、22a……確實地抵接於榖桿，可提高脫粒齒2 2 a、2 2 a ……的脫粒作用，而能減少沒有脫粒的情形。 如第5圖、第8圖所示，在上述承網23的外側，也 就是在餵送鏈9側，是配設有前側網緊壓構件80。前側 網緊壓構件80，是形成爲與承網23略相同的曲率半徑， ® 是配置在形成承網2 3的前側網6 1的延長部上。該前側網 緊壓構件8 0，是被固定設置在可開閉地支承餵送鏈9的 餵送鏈框架81且是設置爲一體，而成爲與餵送鏈框架 1 9 0 —起開閉的構造。在這種構造中，前側網緊壓構件8 〇 ，會將捲繞著餵送鏈8 0的餵送鏈框架8 1鎖定在機體側， 並且將其按壓成讓前側網6 1的餵送鏈9側的側端不會彎 曲。 並且’在該前側網緊壓構件8 1的內側的側面（與脫 粒滾筒2 2外周面相對向的面部），是沿著設置在上述內 -19- (16) M287574 側網6 0或前側網6 1的分隔板7 7，而同方向（延長上） 或平行地突出設置有由棒材或板材等所構成的複數的阻力 構件 82、82……。阻力構件

度H2。也就是說，藉由將分隔板77的高度H2作成高於 阻力構件82的高度H1，讓上述脫粒滾筒23的脫粒齒23a 與分隔板77的搭接範圍，大於脫粒齒23a與阻力構件82 的搭接範圍。 藉由這種構造，在藉由餵送鏈9將榖稈於脫榖裝置內 ® 朝後方搬運時，與分隔板7 6、7 7同樣的’藉由該阻力構 件8 2會將榖稈朝上方抬起，此時讓脫粒齒2 2 a旋轉的話 ，榖桿與脫粒齒的接觸長度會變長’而可提高脫粒動作的 效率。也就是說，由於可使榖稈確實地抵接於脫粒齒’所 以可以提高脫粒齒2 2 a的脫粒作用’可以減少沒有脫粒的 情形。而由於藉由分隔板76、77與阻力構件82 —邊使榖 桿反轉一邊將其朝後方搬運，所以可以提高脫粒動作的效 率。 在榖稈的穗前側，由於脫粒齒2 3 a與分隔板7 7的搭 -20- M287574 (17) 接範圍變得更大，所以可以提高在承網2 3上進行脫粒的 效率’則榖稈的較粗的桿根側不會由於阻力構件的阻力而 被切碎或彎曲。阻力構件82、82……會成爲榖稈利用餵 送鏈9進行搬運時的阻力，在脫榖時藉由使榖稈振動，則 可以讓榖粒落到篩選部3 0。 並且，由於是將阻力構件8 2配置在該分隔板7 7的延 長部上’使其與分隔板77連續，所以該阻力構件82與分 B 隔板77會略同時作用在以餵送鏈9搬運的榖桿。因此， 不容易破壞搬運的榖稈的姿勢，而可有效率地進行脫粒動 作。 〔新型效果〕 在第1創作，在脫粒滾筒的前部下方，是將承網的孔 部作得很大’所以脫粒滾筒的處理物容易漏下到用來進行 搖動篩選的搖動篩選裝置的起端部。藉此，即使大量運送 榖稈且脫粒滾筒的榖粒或碎稿草等的處理物很多，也很難 產生堵塞的情形，能夠以承網前部來促進處理物的漏下動 作。並且，由於在脫粒滾筒的前後中央部下方，設置有承 網的開口面積較小的孔部，處理物較難從該孔部漏下。藉 此，讓從承網的開口面積較小的孔部漏下的處理物的量變 得較小，所以能夠防止處理物集中在搖動篩選裝置的起端 部而產生堵塞的情形，能夠充分地進行篩選處理。 在第2創作，如果將分隔板配置在承網的前部分（入 口側）的話’當運送大量的榖稈時，該分隔板的存在反而 -21 - (18) M287574 會造成榖稈的搬運及脫粒作用的妨礙，所以藉由不將分隔 板配置在承網的前部分，則不會使從扶禾、收割部搬運的 榖桿停滯下來，可在脫粒室內順暢地進行搬運，利用脫粒 齒進行脫粒動作，且可防止在脫榖部的入口附近產生堵塞 。而且藉由配置在後部的分隔板不會有未脫粒的情形產生 〇 在第3創作，由於是在左右複數處進行分割，也就是 ® 在平行於脫粒滾筒的軸芯方向的面進行分割，承網不會碰 觸到餵送鏈或脫榖外殼而進行裝卸，容易進行對於機體的 裝卸作業，容易製造且保管場所也能節省空間。 在第4創作，即使大量運送榖稈且脫粒滾筒的榖粒或 碎稿草等的處理物很多，也很難在承網前部分產生堵塞的 情形，所以能促進處理物對搖動篩選裝置的前滑板的漏下 。另一方面，由於在承網的前後中央部分處理物比較難漏 下，所以漏下到前滑板後部與篩選裝置的處理物的量會變 ® 得較少。於是，可以防止，當從承網的前部分與前後中央 部分漏下的處理物經過前流榖板從篩選裝置落下時，處理 物集中在篩選部產生堵塞的情形，而能夠在篩選部的起端 部充分地進行篩選處理。 在第5創作，在藉由餵送鏈將榖稈朝向後方搬運於脫 榖裝置內時，藉由承網的分隔板與前側網緊壓構件上的阻 力構件來使榖稈朝上方浮起，此時脫粒齒轉動的話，榖稈 與脫粒齒的接觸長度會變長，脫粒效率也會變高。也就是 說，由於可以確實地使榖稈抵接於脫粒齒，所以可以提高 -22- (19) M287574 脫粒齒的脫粒作用，而減低沒有脫粒的情況。而由於是藉 由分隔板與阻力構件一邊使榖稈反轉一邊將其朝向後方搬 運，所以可以提昇脫粒的效率。而由於阻力構件是配置在 該分隔板的延長部上，以與分隔板連續，所以該阻力構件 與分隔板會大略同時作用於搬運的榖稈上。因此，所搬運 的榖稈的姿勢不易破壞，而能高效率地進行脫粒動作。 在第6創作，將脫粒滾筒的脫粒齒與分隔板的搭接範 ® 圍，與脫粒齒與阻力構件的搭接範圍相比更大，所以可以 提昇榖桿的前側位在承網上的脫粒的效率，則榖桿的較粗 的稈根側不會由於阻力構件的阻力而被切碎或彎曲。 【圖式簡單說明】 第1圖是本創作的一實施例的榖物聯合收割機的全體 左側面圖。 第2圖是相同的全體平面圖。 ® 第3圖是脫榖部及篩選部的左側面示意圖。 第4圖是顯示脫粒室的正面圖。

The portion of the front and rear width l 3 is located above the midway portion from the rear of the screening device 50 to the front and rear of the sieve 3 8 or the sieve 3 7 . That is, the portion of the front and rear width L 3 is located on the side of the dust supply port 27 of the threshing chamber 2 1 . Thereby, the hole portion 16-(13) M287574 73 having a large opening area of the mesh member 23 is disposed above the front slide plate 35 and in the vicinity of the dust supply port 27, and the hole portion 74 having a small opening area is disposed in the hole portion 74. The rear of the front slide 35 is above the screening device 50. With this configuration, in the front portion of the web 23 located below the front portion of the threshing drum 22, since the hole portion 73 of the web 23 is made larger, the treatment of the barrel 22 is easily leaked to the shake. The front slide 35 of the starting portion of the screening device 31 is screened. Even if a large amount of the stalk is conveyed, the amount of processing of the granules 22 is not likely to cause clogging, and the leakage of the processed material in the front portion of the web 2 can be promoted, and the conventional slides 35 can be efficiently screened. In the front central portion of the web 23 located below the front and rear central portions of the barrel 204, a hole portion 74 having a small opening area of the web 23 is provided, and it is difficult for the treated material to leak from the hole portion 74. Therefore, after the threshing, the rotation of the threshing drum 21 can be utilized to sufficiently carry out the smashing of the stalk, and the large amount of ® is selected from the front slide 35 through the screening device 50, the sifting screen 38, and the rear slide 36. The pellets, while only the refined niobium particles fall into the first grain conveyor 41. On the other hand, since the amount of the waste material leaked from the hole portion 74 having a small opening area of the web 23 is small, when it is dropped from the screening device 50, it is possible to prevent the processing from being concentrated and causing clogging. Thus, it is possible to prevent the clogging of the front portion of the screen 2 3, and the screening process can be sufficiently performed at the beginning of the shaking screen device. On the other hand, the granules which are sufficiently threshed by the granule reversing drum 21 are easily leaked from the rear portion of the web 23 in which the hole portion 73 having a large opening area is disposed, and the refined granules pass through the sifting sieve 3 8 and the sifting sieve 3 7 and fall to the first transport machine 4 1, uncooked glutinous grains, part of fine draft grass clippings, broken granules, or 未-17- (14) M287574 granules mixed untreated granules, will be sent to the shake At the rear, and at the same time, it is blown away by the screening wind from the wind sorter 32, and sent to the second grain recycling department. The upper surface portion of the inner net 60 and the front side net 61 of the web 23 provided with the holes 73, 74 is a partition plate having a predetermined height formed by a metal plate in the rotation direction of the threshing drum 2 2 . 7 6, 7 7. That is, the 'dividing plates 76, 77' are oriented in the left and right direction with respect to the body. The direction is set to be parallel to the threshing teeth 22a of the threshing drum 22, and is located therebetween when the threshing teeth 2 2 a are rotated. . In the inner net 60, a partition plate 7 is protruded in parallel at a slightly equal position in the front-rear direction of the body, and extends from the abutting portion of the inner net 60 and the front side net 6 1 to the side end of the grain tank 13 unit. On the other hand, in the front side net 61, in addition to the front portion, a partition plate 77 is protruded at a position where the front center portion and the rear portion are appropriately spaced apart from each other, and is abutting portion from the front side net 61 and the inner net 60. Extend to the side of the feed® chain 9 side. The partition plate 7 7 is a portion disposed at a front-rear width L3 of the web 23 and a front-rear width L2. In particular, the protruding portion 23a' of the L-shaped web 23 has a large opening area. The portion between the front and rear widths L2 of the hole portion 73 is disposed at an equal interval between the adjacent partition plates 7 7 and 7 7 so as to be narrower than the front and rear width L3, and the release performance can be improved. The protruding portion 23a is a rear half of the stalk conveying path 9a of the feeding chain 9, and is located below the rear portion of the barrel 221. If the partition plate 77 is provided at a portion which becomes the front-rear width L 1 of the front portion of the front side net 61, when the large amount of the stalk can be handled, the existence of the partition plate 7 7 is reversed -18-(15) M287574 The handling of the stalks and the threshing action are hindered. Therefore, the partitioning plate 7 is not disposed in the front portion of the front side net 61. Thereby, the inner net 60 and the front side net 161 which are respectively protruded from the partition plates 76 and 77 are not provided with the partition plate 77 in the portion of the front side net 61, so that the lifting and harvesting are not performed. The stalk conveyed by the portion 3 is stagnated near the entrance of the detachment portion 20, and can be smoothly conveyed in the granule chamber 21 and threshed by the granules to prevent clogging in the vicinity of the detachment inlet. The stalks ' handled by the feed chain 9 are floated upward by the partition plates 76, 77 disposed at the rear of the net 23, and are simultaneously pressed downward by the spheronizing teeth 22a, 22a. . Therefore, the processing teeth 22a, 22a, ... can be surely abutted against the mast, and the threshing action of the processing teeth 2 2 a, 2 2 a ... can be improved, and the case where there is no threshing can be reduced. As shown in Figs. 5 and 8, the front side net pressing member 80 is disposed on the outer side of the web 23, that is, on the side of the feeding chain 9. The front side net pressing member 80 is formed to have a curvature radius slightly the same as that of the web 23, and is disposed on the extension of the front side net 6 1 forming the web 23. The front side net pressing member 80 is fixedly provided to the feeding chain frame 81 that supports the feeding chain 9 so as to be openable and closable, and is integrally provided to be opened and closed together with the feeding chain frame 190. In this configuration, the front side net pressing member 8 锁定 locks the feeding chain frame 8 1 wound around the feeding chain 80 to the body side, and presses it to feed the front side net 61. The side ends of the 9 sides do not bend. And 'the side surface on the inner side of the front side net pressing member 81 (the surface facing the outer peripheral surface of the barrel 2 2) is disposed along the inner side -19-(16) M287574 side net 60 or the front side net A partitioning plate 7 7 of 6 1 is provided with a plurality of resistance members 82, 82, ... formed of a bar or a plate or the like in the same direction (extended) or in parallel. The resistance members 82, 82, ... are disposed at positions spaced apart from each other by a space corresponding to the front-rear width L2 of the web 23 as the protruding portion 23a, and the respective resistance members 82 are positioned to be continuous with the partition plate 77. It is disposed on the extension of the partition plate 77. In the present embodiment, the resistance member ® 82 is disposed only in the portion of the front and rear width L2 of the web 23, and the resistance member may be disposed in a portion of the front and rear width L3 of the web 23 or a portion of the front and rear width L1. The above-described resistance member 82 has a height H1 which is lower than the height H2 of the partitioning plate 77. That is, by making the height H2 of the partitioning plate 77 higher than the height H1 of the resistance member 82, the overlapping range of the threshing teeth 23a of the threshing drum 23 and the partitioning plate 77 is larger than the threshing teeth 23a and the resistance member. The range of overlap of 82. With this configuration, when the stalk is transported rearward in the detaching device by the feed chain 9, the same as the partition plates 716, VII, by the resistance member 8 2 Lifting upwards, when the threshing teeth 2 2 a are rotated, the contact length of the mast and the threshing teeth becomes longer, and the efficiency of the threshing operation can be improved. That is, since the stalk can be surely abutted against the granules ', the threshing action of the granules 2 2 a can be improved', and the case of no threshing can be reduced. On the other hand, since the partition plates 76 and 77 are conveyed rearward while the mast is reversed, the efficiency of the threshing operation can be improved. On the anterior side of the stalk, since the range of the granules 203-M287574 (17) of the granules 2 3 a and the partitioning plates 7 7 becomes larger, the efficiency of threshing on the nets 2 3 can be improved. The thicker root side of the stalk is not shredded or bent due to the resistance of the resistance member. The resistance members 82, 82, ... become the resistance when the stalk is conveyed by the feed chain 9, and when the stalk is vibrated during the detachment, the granules can be dropped to the screening portion 30. Further, since the resistance member 82 is disposed on the extension of the partition plate 7 to be continuous with the partition plate 77, the resistance member 82 and the sub-B partition 77 act at the same time for feeding. Mast carried by chain 9. Therefore, it is not easy to break the posture of the handled stalk, and the threshing operation can be performed efficiently. [New effect] In the first creation, the hole portion of the net is made very large under the front portion of the barrel, so the treatment of the barrel is easily leaked to the shaking screen for shaking screening. Ends. As a result, even if a large amount of the stalk is transported and the processing material such as the granules or the scum of the granules is large, it is difficult to cause clogging, and the leakage operation of the treated material can be promoted by the front portion of the net. Further, since the hole portion having a small opening area of the mesh is provided below the front and rear center portions of the barrel, the processed material is less likely to leak from the hole. With this configuration, the amount of the processed material that leaks from the hole portion having a small opening area of the mesh is reduced. Therefore, it is possible to prevent the processed material from being concentrated on the starting end portion of the shaking and screening device and causing clogging, and it is possible to sufficiently perform the clogging. Screening process. In the second creation, if the partition plate is placed on the front part of the net (inlet side), when the large amount of stalk is transported, the existence of the partition is instead - 21 - (18) M287574 causes stalks Since the partitioning plate is not disposed in the front portion of the net, the mast that is transported from the weaving and harvesting portions is not stopped, and can be smoothly transported and used in the threshing chamber. The threshing teeth perform a threshing operation and prevent clogging in the vicinity of the entrance of the untwisting portion. Moreover, since the partition plate disposed at the rear portion is not un-granulated, the third creation is caused, since the division is performed at the right and left, that is, the division is performed in a plane parallel to the axis direction of the barrel. The carrier network does not touch the feeding chain or the unloading casing for loading and unloading, and it is easy to carry out loading and unloading operations for the body, which is easy to manufacture and saves space in the storage place. In the fourth creation, even if a large amount of the stalk is transported and the processing materials such as the granules of the threshing drum or the squeegee are many, it is difficult to cause clogging in the front portion of the net, so that the treatment can be promoted before the shaking of the screening device. The skateboard is leaking. On the other hand, since the treatment of the central portion of the front and rear of the screen is relatively difficult to leak, the amount of the treatment that leaks to the rear of the front slide and the screening device becomes less. Therefore, it is possible to prevent that when the processed material leaking from the front portion and the front and rear central portions of the net is dropped from the screening device through the front flow board, the processed matter concentrates in the case where the screening portion is clogged, and can be in the screening portion. The ends are sufficiently subjected to screening treatment. In the fifth creation, when the stalk is conveyed rearward in the untwisting device by the feeding chain, the stalk is floated upward by the partitioning plate of the net and the resistance member on the front net pressing member. At this time, when the threshing tooth rotates, the contact length of the stalk and the threshing tooth becomes long, and the threshing efficiency also becomes high. That is to say, since the stalk can be surely abutted against the granule, the granulation of the -22-(19) M287574 threshing tooth can be improved, and the case of no threshing can be reduced. Further, since the stalk is moved backward by the partition plate and the resistance member, the efficiency of the threshing can be improved. Since the resistance member is disposed on the extension of the partition plate to be continuous with the partition plate, the resistance member and the partition plate act substantially simultaneously on the conveyed stalk. Therefore, the posture of the handled stalk is not easily broken, and the threshing operation can be performed efficiently. In the sixth creation, the overlapping range of the threshing teeth of the threshing drum and the partitioning plate is larger than the overlapping range of the threshing teeth and the resistance member, so that the front side of the mast can be raised on the bearing net. The efficiency of threshing, the thicker stalk side of the mast is not shredded or bent by the resistance of the resistance member.
