As a result, the sieve sorting process is performed on the sorting object leaked from the receiving net 18. And by this sieving selection process, the grain etc. with large specific gravity of the selection object are leaked. In addition, sawdust having a small specific gravity is transferred to the shredding and discharging mechanism 23 at the rear.

唐箕20は、揺動選別機構19の前下方に位置して、左右向きの唐箕軸20Aを中心にして左側面視左回りに回転する。これにより、揺動選別機構19に向かう選別風を発生させて、選別対象物に対して風力選別処理を施す。そして、この風力選別処理により、細かい稈屑などの揺動選別機構19からの漏下を抑制する。又、揺動選別機構19から漏下した細かい稈屑などを後方の細断排出機構23に風力搬送する。   The red pepper 20 is located in front of and below the swinging selection mechanism 19 and rotates counterclockwise as viewed from the left side about the horizontal hot shaft 20A. Thereby, the sorting wind toward the swing sorting mechanism 19 is generated, and the sorting target is subjected to the wind sorting process. And by this wind power sorting process, leakage from the rocking sorting mechanism 19 such as fine sawdust is suppressed.

I am letting. Further, the side wall body 16 has a lower portion in the closed position in which a lower connecting member 50 that is in surface contact with the lower end portion 46A of the outer wall plate 46 and a peripheral wall portion 45A on the lower side of the inner wall plate 45 are separated in the lateral direction of the body. Thus, a lower opening extending along the inner wall plate 45 and the outer wall plate 46 is formed. The lower opening extends from the front wall plate 47 to the rear wall plate 48 in the longitudinal direction of the machine body. The width in the left-right direction of the upper opening is narrower than the width in the left-right direction of the lower opening.

これにより、側壁体16の開き位置においては、側壁体16の揺動支点から離れていることによって歪みが生じ易い外壁板46の下端部(遊端部)46Aを、下側連結部材50が下方から受け止めて支持するようになる。その結果、開き位置での側壁体16の姿勢を、より歪みの少ない良好な姿勢に保つことができる。   As a result, at the opening position of the side wall body 16, the lower connecting member 50 is positioned below the lower end portion (free end portion) 46A of the outer wall plate 46, which is likely to be distorted by being away from the swing fulcrum of the side wall body 16.

これにより、側壁体16の揺動支点から離れていることによって歪みが生じ易い内壁板45の下端部(遊端部)での保形性を、補助部材56によって効果的に高めることができる。そして、その補助部材56の側面56aを枠状面部45Bの下側面部分45Baとして使用することから、側壁体16の閉じ位置においてシール部材55を介して密接するフレーム部14Aの左側面14Acと内壁板45の枠状面部45Bとの下部側での密接状態を良好に保つことができる。   As a result, the auxiliary member 56 can effectively enhance the shape retention at the lower end portion (free end portion) of the inner wall plate 45 that is likely to be distorted by being away from the swing fulcrum of the side wall body 16. Since the side surface 56a of the auxiliary member 56 is used as the lower side surface portion 45Ba of the frame-like surface portion 45B, the left side surface 14Ac and the inner wall plate of the frame portion 14A are in close contact with each other through the seal member 55 at the closed position of the side wall body 16. The close state on the lower side with the frame-like surface portion 45B of 45 can be kept good.

図7〜9に示すように、シール部材55は、脱穀フレーム14のフレーム部14Aにおける左側面14Acの前側面部14aに接着する縦長の前側シール部55A、左側面14Acの後側面部14bに接着する縦長の後側シール部55B、左側面14Acの上側面部14cに接着する横長の上側シール部55C、及び、側壁体16の内壁板45における枠状面部45Bの下側面部分45Ba(補助部材56の側面56a)に接着する横長の下側シール部55D、を備えている。   As shown in FIGS. 7 to 9, the seal member 55 is bonded to the longitudinal front seal portion 55 </ b> A that adheres to the front side surface 14 a of the left side surface 14 Ac in the frame portion 14 </ b> A of the threshing frame 14 and the rear side surface portion 14 b of the left side surface 14 Ac. The vertically long rear seal portion 55B, the horizontally long upper seal portion 55C adhered to the upper side surface portion 14c of the left side surface 14Ac, and the lower side surface portion 45Ba (auxiliary member 56) of the frame-shaped surface portion 45B of the inner wall plate 45 of the side wall body 16. The side face 56a) is attached with a horizontally long lower seal portion 55D.

図5及び図7〜10に示すように、側壁体16は、内壁板45の前半部と後半部とのそれぞれに、側壁体16の閉じ位置において受網18の下方に入り込むガイド部57を備えている。各ガイド部57は、閉じ位置での受網18の下方への入り込み量が下方側ほど大きくなる状態で内壁板45の上下中間部から右下方に延出するガイド面57Aを備えている。又、ガイド面57Aから内壁板45にわたる前面57Bと後面57Cと底面57Dとを備えている。そして、これらの各面57A〜57Dを備えることにより、内壁板45との間に閉塞空間58を形成する箱状に構成している。又、それらの前後幅を、内壁板45の前後幅の半分よりも少し狭い前後幅に設定することにより、前後のガイド部57の間に、受網18の左端部から揺動選別機構19の左端部への選別対象物の漏下を許容する隙間59を形成している。   As shown in FIGS. 5 and 7 to 10, the side wall body 16 includes guide portions 57 that enter the lower side of the receiving net 18 at the closed position of the side wall body 16 in each of the front half portion and the rear half portion of the inner wall plate 45. ing. Each guide portion 57 is provided with a guide surface 57A extending from the upper and lower intermediate portion of the inner wall plate 45 to the lower right side in a state in which the amount of downward entry of the receiving net 18 at the closed position increases toward the lower side. Further, a front surface 57B, a rear surface 57C, and a bottom surface 57D extending from the guide surface 57A to the inner wall plate 45 are provided. And by providing these each surface 57A-57D, it has comprised in the box shape which forms the obstruction | occlusion space 58 between the inner wall board 45. FIG. Further, by setting the front-rear widths thereof to be slightly smaller than the front-rear width of the inner wall plate 45, the swing sorting mechanism 19 is moved from the left end of the receiving net 18 between the front-rear guide parts 57. A gap 59 is formed to allow the sorting object to leak to the left end.

この構成により、扱胴17の回転方向上手側に位置することにより漏下量が多くなる受網18の左端部から濾過した選別対象物の多くを、各ガイド部57のガイド面57Aにより、揺動選別機構19の左右中央側に案内することができる。これにより、受網18から漏下した選別対象物が、揺動選別機構19の左端側に集中して供給されることに起因した揺動選別機構19での選別不良の発生を防止することができる。   With this configuration, most of the objects to be filtered filtered from the left end portion of the receiving net 18, which has a large amount of leakage due to being positioned on the upper side in the rotational direction of the handling cylinder 17, are shaken by the guide surfaces 57 </ b> A of the respective guide portions 57. It can be guided to the left and right center side of the dynamic sorting mechanism 19. As a result, it is possible to prevent a sorting defect from occurring in the swing sorting mechanism 19 due to the sorting objects leaking from the receiving net 18 being concentrated and supplied to the left end side of the swing sorting mechanism 19. it can.

そして、各ガイド部57を箱状に構成することにより、側壁体16の保形性を更に高めることができる。これにより、開き位置での側壁体16の姿勢を、より歪みの少ない良好な姿勢に保つことができる。   And the shape retention property of the side wall body 16 can further be improved by comprising each guide part 57 in box shape. Thereby, the attitude | position of the side wall body 16 in an open position can be maintained in the favorable attitude | position with less distortion.

又、各ガイド部57は、内壁板45との間に閉塞空間58を形成することから、受網18から漏下した選別対象物が内壁板45と各ガイド部57との間に入り込む不具合の発生を防止することができる。これにより、穀粒が内壁板45と各ガイド部57との間に入り込むことに起因した穀粒回収効率の低下を回避することができる。又、稈屑などが内壁板45とガイド部57との間に入り込んで内壁板45及びガイド部57に付着することを防止することができる。その結果、脱穀装置5の内部を清掃する際に要する手間を軽減することができる。   Further, since each guide portion 57 forms a closed space 58 between the inner wall plate 45 and the selection target object that has leaked from the receiving net 18, the selection target object enters between the inner wall plate 45 and each guide portion 57. Occurrence can be prevented. Thereby, the fall of the grain collection | recovery efficiency resulting from a grain entering between the inner wall board 45 and each guide part 57 can be avoided. Further, it is possible to prevent the sawdust or the like from entering between the inner wall plate 45 and the guide portion 57 and adhering to the inner wall plate 45 and the guide portion 57. As a result, it is possible to reduce the labor required for cleaning the inside of the threshing device 5.

各ガイド部57において、ガイド面57A及び底面57Dは、それらが連なるように第1鋼板60を屈曲して形成している。前面57Bは第2鋼板61により、又、後面57Cは第3鋼板62により、側壁体16の内壁板45と第1鋼板60との間に入り込む前後方向視三角形状に形成している。そして、第1鋼板60の前端部に第2鋼板61を溶接し、第1鋼板60の後端部に第3鋼板62を溶接して、ガイド部57を構成している。各ガイド部57は、側壁体16の内壁板45との溶接により、内壁板45との間に閉塞空間58を形成している。   In each guide portion 57, the guide surface 57A and the bottom surface 57D are formed by bending the first steel plate 60 so that they are continuous. The front surface 57B is formed of a second steel plate 61, and the rear surface 57C is formed of a third steel plate 62 in a triangular shape as viewed in the front-rear direction and enters between the inner wall plate 45 of the side wall body 16 and the first steel plate 60. And the 2nd steel plate 61 is welded to the front-end part of the 1st steel plate 60, and the 3rd steel plate 62 is welded to the rear-end part of the 1st steel plate 60, and the guide part 57 is comprised. Each guide portion 57 forms a closed space 58 with the inner wall plate 45 by welding with the inner wall plate 45 of the side wall body 16.

図4、図5及び図10に示すように、脱穀フレーム14のフレーム部14Aは、その後縁部分14Aaの下端部にガスダンパ44のピストンロッド44Aを連結する第1連結軸63と、第1連結軸63を支点にして揺動する揺動部材64とを備えている。側壁体16は、その取付部16Aにガスダンパ44のシリンダチューブ44Bを連結する第2連結軸65を備えている。ガスダンパ44は、側壁体16の開き位置への上昇揺動とともに伸長するように、フレーム部14Aの第1連結軸63と側壁体16の第2連結軸65とにわたって架設している。   As shown in FIGS. 4, 5, and 10, the frame portion 14 </ b> A of the threshing frame 14 includes a first connection shaft 63 that connects the piston rod 44 </ b> A of the gas damper 44 to the lower end portion of the rear edge portion 14 </ b> Aa, and a first connection shaft. And an oscillating member 64 which oscillates around 63 as a fulcrum. The side wall body 16 includes a second connecting shaft 65 that connects the cylinder tube 44B of the gas damper 44 to the mounting portion 16A. The gas damper 44 is installed over the first connecting shaft 63 of the frame portion 14 </ b> A and the second connecting shaft 65 of the side wall body 16 so as to extend as the side wall body 16 moves upward and downward to the open position.

揺動部材64は、フレーム部14Aとガスダンパ44との間に配置している。そして、その上下方向視での形状を、側壁体16の閉じ位置においてガスダンパ44のシリンダチューブ44Bに外嵌する略U字状に形成している。又、その上下長さを、側壁体16の開き位置への到達に伴って、ガスダンパ44のシリンダチューブ44Bとフレーム部14Aの第1連結軸63との間に入り込む長さに設定している。これにより、揺動部材64を、側壁体16の開き位置からの下降を阻止する下降阻止機構Cとして機能させている。   The swing member 64 is disposed between the frame portion 14 </ b> A and the gas damper 44. The shape in the vertical direction is formed in a substantially U shape that is externally fitted to the cylinder tube 44B of the gas damper 44 at the closed position of the side wall body 16. The vertical length is set to a length that enters between the cylinder tube 44B of the gas damper 44 and the first connecting shaft 63 of the frame portion 14A as the side wall body 16 reaches the open position. Accordingly, the swing member 64 is caused to function as a lowering prevention mechanism C that prevents the side wall body 16 from being lowered from the open position.

上記の構成により、側壁体16の開き位置への揺動操作に要する操作力を、ガスダンパ44の作用によって軽減することができる。その結果、側壁体16を開き位置に揺動操作する際の操作性を向上させることができる。   With the above configuration, the operating force required for the swinging operation of the side wall body 16 to the open position can be reduced by the action of the gas damper 44. As a result, the operability when swinging the side wall body 16 to the open position can be improved.

又、側壁体16が開き位置に到達すると、このときにガスダンパ44の上側に位置する揺動部材64が、ガスダンパ44のシリンダチューブ44Bとフレーム部14Aの第1連結軸63との間に自動的に入り込んで、ガスダンパ44の収縮作動を阻止するとともに側壁体16の開き位置からの下降を阻止する。これにより、ガスダンパ44においてガス漏れが生じた場合であっても、そのガス漏れに起因して側壁体16が開き位置から不測に下降する不具合の発生を、その不具合の発生を阻止するための専用の操作を要することなく、確実に阻止することができる。   When the side wall body 16 reaches the open position, the swinging member 64 located above the gas damper 44 at this time automatically moves between the cylinder tube 44B of the gas damper 44 and the first connecting shaft 63 of the frame portion 14A. The gas damper 44 is prevented from contracting and the side wall body 16 is prevented from descending from the open position. As a result, even when a gas leak occurs in the gas damper 44, the occurrence of a problem that the side wall body 16 is unexpectedly lowered from the open position due to the gas leak is prevented from occurring. It is possible to reliably prevent the operation without requiring the operation.

And it is provided in the extension end of the support arm 70 before and behind extending from the lower edge part 14Ad of the frame part 14A leftward. Each engaging tool 68 includes a resin fixed member 71 fixed to the lower end portion of the side wall body 16 and a resin movable member 72 engaged and connected to the fixed member 71 so as to be swingable up and down. Each fixing member 71 includes a recess 71 </ b> A that allows the shaft member 69 to be engaged, and an elastic biasing portion (not shown) that biases the movable member 72 downward. Each movable member 72 is formed in a hook shape that engages with a shaft member 69 engaged with the recess 71 </ b> A of the fixed member 71 by downward swing. Further, it swings up and down over an engagement position where it engages with the shaft member 69 engaged with the recess 71 </ b> A of the fixing member 71 and an upper release position where the engagement with the shaft member 69 is released. At the left end portion thereof, an operation portion 72A is provided which enables an upward swing operation against the action of the elastic urging portion manually.

これにより、側壁体16を閉じ位置に揺動操作すると、ロック機構66における各弾性付勢部の作用と各連動部72Bの作用により、側壁体16の閉じ位置への到達に連動して側壁体16を自動的に閉じ位置にて固定保持することができる。そして、このロック機構66による側壁体16の閉じ位置での固定保持は、ロック機構66における各可動部材72の操作部72Aを手動操作することにより、簡単に解除することができる。   Accordingly, when the side wall body 16 is swung to the closed position, the side wall body 16 is interlocked with the arrival of the side wall body 16 to the closed position by the action of each elastic urging portion in the lock mechanism 66 and the action of each interlocking portion 72B. 16 can be automatically held fixed in the closed position. The fixing and holding of the side wall body 16 in the closed position by the lock mechanism 66 can be easily released by manually operating the operation portions 72A of the movable members 72 in the lock mechanism 66.

図11及び図12に示すように、脱穀フレーム14のフレーム部14Aは、前述した前後の支持アーム70を備えている。そして、前後の支持アーム70に、各支持アーム70の左方への延出長さを調節可能にすることにより、各軸部材69の機体横方向での位置調節を可能にする位置調節機構Dを備えている。これにより、脱穀フレーム14や側壁体16の製造誤差などに起因して、側壁体16の開閉方向において、側壁体16の閉じ位置とロック機構66による側壁体16の固定位置とにズレが生じた場合には、その位置ズレを位置調節機構Dによって吸収することができる。その結果、脱穀フレーム14や側壁体16の製造誤差などにかかわらず、側壁体16の閉じ位置とロック機構66による側壁体16の固定位置とを一致させることができ、ロック機構66による側壁体の閉じ位置での固定保持を適正に行うことができる。   As shown in FIGS. 11 and 12, the frame portion 14A of the threshing frame 14 includes the front and rear support arms 70 described above. A position adjustment mechanism D that allows the position of each shaft member 69 to be adjusted in the lateral direction of the machine body by allowing the front and rear support arms 70 to adjust the extension length of each support arm 70 to the left. It has. Thereby, due to manufacturing errors of the threshing frame 14 and the side wall body 16, a deviation occurred between the closed position of the side wall body 16 and the fixing position of the side wall body 16 by the lock mechanism 66 in the opening and closing direction of the side wall body 16. In some cases, the positional deviation can be absorbed by the position adjusting mechanism D. As a result, the closed position of the side wall body 16 and the fixed position of the side wall body 16 by the lock mechanism 66 can be matched regardless of the manufacturing error of the threshing frame 14 or the side wall body 16. Fixing and holding in the closed position can be performed properly.

各支持アーム70は、フレーム部14Aの下縁部分14Adに固定する平面視略U字状の第1部材73と、軸部材69を支持する前後一対の第2部材74とを備えている。そして、各第2部材74に、機体の横方向に長い2つの長孔Da,Dbを機体の横方向に並べて形成している。又、第1部材73における前後の両部に、各第2部材74における脱穀フレーム側の長孔Daを利用した第1部材73と第2部材74とのボルト連結を可能にする連結部Dcと、各第2部材74における側壁体側の長孔Dbに機体横方向に移動可能に係入する突起Ddとを、機体の横方向に並べて備えている。そして、これらの2つの長孔Da,Dbと連結部Dcと突起Ddとから、各支持アーム70に備えた位置調節機構Dを構成している。   Each support arm 70 includes a first member 73 having a substantially U shape in plan view that is fixed to the lower edge portion 14Ad of the frame portion 14A, and a pair of front and rear second members 74 that support the shaft member 69. In each second member 74, two long holes Da and Db that are long in the lateral direction of the machine body are formed side by side in the lateral direction of the machine body. Moreover, the connection part Dc which enables the bolt connection of the 1st member 73 and the 2nd member 74 using the long hole Da by the side of the threshing frame in each 2nd member 74 in the front and back both parts in the 1st member 73, The projections Dd that are movably engaged with the long holes Db on the side wall of each second member 74 are arranged in the horizontal direction of the machine body. The two long holes Da, Db, the connecting portion Dc, and the projection Dd constitute a position adjusting mechanism D provided in each support arm 70.

この構成によると、各支持アーム70において、第1部材73の各連結部Dcと各第2部材74の脱穀フレーム側の長孔Daとを利用して第1部材73と第2部材74とをボルト75にて仮止めし、かつ、第1部材73の各突起Ddを各第2部材74の側壁体側の長孔Dbに係入することにより、第1部材73に対する各第2部材74の機体横方向への移動を許容しながら、第1部材73に対する各第2部材74の揺動変位を阻止することができる。つまり、第1部材73と各第2部材74とのボルト連結箇所を少なくしながら、第1部材73に対する各第2部材74の回り止めを確実に行うことができる。これにより、機体横方向での軸部材69の位置調節を簡単に行うことができる。そして、軸部材69の位置調節後に仮止め状態のボルト75を本締めして第1部材73と各第2部材74とをボルト連結することにより、軸部材69を適正位置にて簡単に固定することができる。つまり、各位置調節機構Dによる軸部材69の位置調節固定を、簡単かつ適正に行うことができる。   According to this configuration, in each support arm 70, the first member 73 and the second member 74 are connected to each other by using each connecting portion Dc of the first member 73 and the long hole Da on the threshing frame side of each second member 74.
