Description
本発明は、タインを多数設けた掻き込みリールを具備して、掻き込みリールにより穀稈を掻込みながら収穫する普通型のコンバインに関する。
The present invention relates to an ordinary combine that has a scraping reel provided with a large number of tines and harvests while scraping the cereal with the scraping reel.
従来、普通型のコンバインの一形態として特許文献1に開示されたものがある。かかるコンバインは刈取部を有しており、刈取部は、穀稈を掻込む掻き込みリールと、掻き込みリールにより掻き込まれた穀稈の根元部を刈り取る刈刃と、刈刃により刈り取られた穀稈を掻き込みながら横送りする掻込オーガを横架したプラットフォームと、掻込オーガにより横送りされた穀稈を後方へ搬送する搬送コンベアを内蔵したフィーダハウスとを具備している。
Conventionally, there is one disclosed in Patent Document 1 as one form of a general combine. Such a combine has a cutting part, and the cutting part was cut by the cutting blade, the cutting blade that cuts the root part of the culm that was scraped by the scraping reel, and the cutting blade. It includes a platform on which a scraping auger that is laterally fed while scraping the cereal and a feeder house having a built-in conveyor that transports the cereal that has been laterally fed by the scraping auger to the rear.
掻き込みリールは、左右一対のリール支持アームの先端部間にリール支軸を介して回転自在に支持されている。そして、掻き込みリールは、左右一対の回転支持体と、両回転支持体間に架設した複数のタインバーと、各タインバーに取り付けた複数のタインとを具備している。タインは、一対のタイン本片と、両タイン本片の上端部を連結する連結片とが一本の丸棒材によって一体的に形成されている。つまり、一対のタインが二叉状に形成されている。連結片はタインバーの周面に略沿わせて湾曲させて形成することで、タインバーの周面に嵌合状態にて着脱自在に係合して、タインバーに一対のタイン本片を着脱することができるようにいる。そして、タインバーには、長手方向にスリットを有する筒状のタインカバーをスリットが開閉する方向に弾性変形させて取り付けることで、タインカバーによりタインの連結片を被覆している。このようにして、タインバーにタインを簡単に取り付けることができるようにするとともに、連結片にわら屑等が絡み付かないようにしている。
The scraping reel is rotatably supported between the front ends of a pair of left and right reel support arms via a reel support shaft. The scraping reel includes a pair of left and right rotation supports, a plurality of tine bars installed between the two rotation supports, and a plurality of tines attached to each tine bar. In the tine, a pair of tine pieces and a connecting piece for connecting upper ends of both tine pieces are integrally formed by a single round bar. That is, a pair of tines are formed in a bifurcated shape. The connecting piece is formed by being curved substantially along the peripheral surface of the tine bar, so that the connecting piece can be detachably engaged with the peripheral surface of the tine bar in a fitted state, and a pair of tine main pieces can be attached to and detached from the tine bar. I can do it. A tine connecting piece is covered with the tine cover by attaching a cylindrical tine cover having a slit in the longitudinal direction to the tine bar while being elastically deformed in the direction in which the slit opens and closes. In this way, it is possible to easily attach the tine to the tine bar, and to prevent the trash from being entangled with the connecting piece.
ところが、前記したタインの取付構造では、タイン本片が破損等した際に、タインバーからタイン本片を取り外す作業が煩雑であった。すなわち、タイン本片の取り外し作業をする際には、まず、タインバーからタインカバーを取り外すことで、タインの連結片を露出させ、タインバーに係合している連結片を係合解除させることで、タインを取り外すようにしている。この際、連結片はタインバーの周面に堅実に嵌合して、タインバーから簡単に脱落しないようにしているため、係合解除する際には逐一専用の工具を用意する必要性がある。そのため、この点からもタインの取り外し作業が煩雑になっていた。

次に、掻き込みリール24の構成を具体的に説明する。すなわち、掻き込みリール24は、図3~図5に示すように、プラットフォーム21の後端上部に左右方向に軸線を向けたアーム支軸30を横架している。アーム支軸30の左右側端部には前後方向に伸延する左右一対の支持アーム31,31の基端部(後端部)を枢支している。そして、各支持アーム31の中途部とプラットフォーム21の側壁との間にリール昇降シリンダ32を介設して、アーム支軸30を中心に両支持アーム31,31を昇降可能としている。
Next, the configuration of the scraping reel 24 will be specifically described. That is, as shown in FIGS. 3 to 5, the scraping reel 24 lays the arm support shaft 30 with its axis line in the left-right direction on the upper rear end of the platform 21. The left and right end portions of the arm support shaft 30 pivotally support the base end portions (rear end portions) of the pair of left and right support arms 31 and 31 extending in the front-rear direction. A reel raising / lowering cylinder 32 is interposed between the middle part of each supporting arm 31 and the side wall of the platform 21 so that both the supporting arms 31 and 31 can be raised and lowered around the arm support shaft 30.
両支持アーム31,31の先端部(前端部)間には、左右方向に伸延するリール支軸33をその軸芯廻りに回転自在に軸架するとともに、リール支軸33を前後方向に始端対位置調節自在としている。リール支軸33の左右側端部には、左右一対の回転支持体34,34を左右に対向させてそれらの中心部を取り付けている。両回転支持体34,34は、金属製の板状体を正五角形状に形成して、左右に対向する各角部(頂部)間にタインバー枢支体35を介して左右方向に伸延するパイプ(円管)状のタインバー36をその軸線廻りに回転自在に横架している。
Between the front end portions (front end portions) of both the support arms 31, 31, a reel support shaft 33 extending in the left-right direction is rotatably supported around its axis, and the reel support shaft 33 is paired with a leading end in the front-rear direction. The position is adjustable. A pair of left and right rotation supports 34, 34 are opposed to the left and right ends of the reel support shaft 33 so that the center portions thereof are attached. Both rotary supports 34, 34 are formed of a metal plate-like body in a regular pentagon shape, and are pipes extending in the left-right direction via tine bar pivots 35 between the left and right corners (tops). A (circular tube) tine bar 36 is laid horizontally so as to be rotatable about its axis.
各タインバー36には、左右方向に一定の間隔を開けて複数のタイン37を垂下状に取り付けている。右側の回転支持体34の外側方にはリール支軸33の軸芯とは偏倚した軸芯廻りに回転するタイン姿勢保持用回転支持体38を配置している。
A plurality of tines 37 are attached to each tine bar 36 in a hanging manner with a certain interval in the left-right direction. On the outer side of the right rotation support 34, a tine posture holding rotation support 38 that rotates about an axis that is offset from the axis of the reel support shaft 33 is disposed.
そして、タイン姿勢保持用回転支持体38は、回転支持体34と略同形状に形成して、各角部(頂部)にリンク枢支体39を取り付け、リンク枢支体39と近接するタインバー36の右側端とをリンク40を介して連結してタイン姿勢保持機構41を形成している。
The tine posture holding rotation support 38 is formed in substantially the same shape as the rotation support 34, and a link pivot 39 is attached to each corner (top), and the tine bar 36 adjacent to the link pivot 39 is attached. Are connected via a link 40 to form a tine posture holding mechanism 41.
このようにして、タイン姿勢保持機構41は、回転移動するタイン37の内、少なくとも植立穀稈に作用するタイン37は所定の垂下姿勢に保持して、かかる垂下姿勢に保持されたタイン37が植立穀稈に掻き込み作用するようにしている。
In this way, the tine posture holding mechanism 41 holds at least a tine 37 that acts on the planted cereal among the tines 37 that rotate and holds the tine 37 held in the hanging posture. It works to stir the planted cereal.
アーム支軸30の右側端とリール支軸33の右側端との間には、エンジン11に連動連結した伝動機構42を介設して、リール支軸33を図25の左側面視にて反時計廻りRに回転させるようにしている。
Between the right end of the arm support shaft 30 and the right end of the reel support shaft 33, a transmission mechanism 42 linked to the engine 11 is provided so that the reel support shaft 33 is opposite to the left view of FIG. It is made to rotate clockwise R.
このようにして、リール支軸33を図25の左側面視にて反時計廻りRに回転させると、リール支軸33に取り付けた左右一対の回転支持体34,34も反時計廻りRに回転して、両回転支持体34,34間にタインバー36を介して取り付けたタイン37は回転支持体34の外周廻りに移動する。この際、タイン姿勢保持機構41により各タイン37は垂下姿勢を保持したまま移動して、植立穀稈に堅実に掻き込み作用する。
Thus, when the reel support shaft 33 is rotated counterclockwise R in the left side view of FIG. 25, the pair of left and right rotation supports 34, 34 attached to the reel support shaft 33 are also rotated counterclockwise R. Then, the tine 37 attached between the rotating supports 34 and 34 via the tine bar 36 moves around the outer periphery of the rotating support 34. At this time, each tine 37 is moved while maintaining the suspended posture by the tine posture holding mechanism 41, and the tine posture is firmly raked into the planted cereal.
次に、タインバー36の取付構造とタイン37の取付構造を具体的に説明する。

まず、タインバー36を直接支持する回転支持体34について、図6~図14を参照しながら説明する。回転支持体34は、正多角形(本実施形態では正五角形)に形成した薄肉金属板の中心部に円形口50を形成し、円形口50の周囲に五個の逆三角形口51を略均等に間隔を開けて形成している。 (
First, the
そして、かかる外形状の回転支持体34は、五つの角部(頂部)52を除くほぼ全体的を外方に凸条となすエンボス加工を施すことで、リール支軸33に取り付けるリング状のハブ部53と、ハブ部53から放射線方向に直状に伸延する五本のスポーク部54と、周方向に隣接するスポーク部の先端部同士を連結する直状の連結部55とを一体成形している。56はスポーク部54の中央部に長手方向に伸延させてエンボス加工した凹条部である。このようにして、回転支持体34の構成部品点数削減化と軽量化と高剛性化を実現している。
The outer-shaped rotation support 34 is a ring-shaped hub that is attached to the reel support shaft 33 by embossing the outermost part excluding the five corners (tops) 52 into ridges outward. The part 53, the five spoke parts 54 that extend straight from the hub part 53 in the radial direction, and the straight connection part 55 that connects the tips of the spoke parts adjacent in the circumferential direction are integrally molded. Yes. Reference numeral 56 denotes a concave strip portion that is elongated in the longitudinal direction at the center portion of the spoke portion 54 and embossed. In this way, the number of components of the rotary support 34 is reduced, and the weight and the rigidity are increased.
角部(頂部)52は、外側面がスポーク部54や連結部55の外側面に対して内側方に位置して段付き凹状面を形成する連結用板状片52aとなしている。そして、連結用板状片52aの中途部に、タインバー36の側端部を配置するためのタインバー配置用凹部52bを形成しており、タインバー配置用凹部52bは放射線方向と左右側方に開口する凹状に形成している。52cは連結用板状片52aに左右方向に開口させて形成したボルト孔であり、タインバー配置用凹部52bを間に挟んで二箇所に形成している。
The corner portion (top portion) 52 is formed as a connecting plate-like piece 52 a whose outer surface is positioned inward with respect to the outer surfaces of the spoke portion 54 and the connecting portion 55 to form a stepped concave surface. And the tine bar arrangement | positioning recessed part 52b for arrange | positioning the side edge part of the tine bar 36 is formed in the middle part of the connecting plate-shaped piece 52a, and the tine bar arrangement | positioning recessed part 52b opens to a radiation direction and the left-right side. It is formed in a concave shape. Reference numeral 52c denotes a bolt hole formed by opening the connecting plate-like piece 52a in the left-right direction, and is formed at two locations with a tine bar disposition recess 52b interposed therebetween.
角部(頂部)52の連結用板状片52aには、図15に示すように、タインバー枢支体35を介してタインバー36の側端部を着脱自在に取り付けるようにしている。
As shown in FIG. 15, a side end portion of the tine bar 36 is detachably attached to the connecting plate-like piece 52 a of the corner portion (top portion) 52 via a tine bar pivotal support body 35.
すなわち、タインバー枢支体35は、タインバー36をその軸線廻りに回転自在に支持する筒状のボス部61と、ボス部61の外周面から外方へ張り出し状に突設した一対の連結用耳片62,62とから形成している。そして、両連結用耳片62,62の内側面側に位置するボス部61の外周面には、図24に示すように、タインバー配置用凹部52bを形成する連結用板状片52aの周縁部を嵌入させるための嵌入溝61aを形成している。嵌入溝61aの一側壁は連結用耳片62,62が形成しており、タインバー配置用凹部52bに嵌入溝61aを介してタインバー枢支体35を嵌入させた際には、連結用板状片52aの外側面に連結用耳片62,62の内側面が面接触して内外側に重合状態となるようにしている。この際、連結用耳片62,62には左右方向に開口するボルト孔62a,62aが形成されており、これらボルト孔62a,62aは連結用板状片52aに形成したボルト孔52c,52cと左右方向に整合するようにしている。
That is, the tine bar pivotal support body 35 has a cylindrical boss portion 61 that supports the tine bar 36 so as to be rotatable about its axis, and a pair of connecting ears protruding outward from the outer peripheral surface of the boss portion 61. The pieces 62 and 62 are formed. And as shown in FIG. 24, the outer peripheral surface of the boss | hub part 61 located in the inner surface side of both the connection ear pieces 62 and 62 is the peripheral part of the connection plate-shaped piece 52a which forms the recessed part 52b for tine bar arrangement | positioning. An insertion groove 61a is formed for inserting the. One side wall of the insertion groove 61a is formed with connection ear pieces 62, 62. When the tine bar pivotal support body 35 is inserted into the tine bar arrangement recess 52b via the insertion groove 61a, the connection plate-like piece is formed. The inner side surfaces of the connecting ear pieces 62, 62 are brought into surface contact with the outer surface of 52a so as to be superposed on the inner and outer sides. At this time, bolt holes 62a and 62a that open in the left-right direction are formed in the connecting ear pieces 62 and 62, and these bolt holes 62a and 62a are connected to the bolt holes 52c and 52c formed in the connecting plate-like piece 52a. They are aligned in the left-right direction.
したがって、整合したボルト孔52c,62aに外側方から連結ボルト63を挿通して連結ボルト63の先端部にナット64を螺着することで、連結用板状片52aにタインバー36の側端部を挿通したタインバー枢支体35を取り付けることができる。この際、タインバー36の側端部にはその軸芯と直交する方向に貫通孔70が形成されており、タインバー枢支体35のボス部61にタインバー36の側端部を挿通して、ボス部61の外側端面よりも外側方へ貫通孔70を配置するとともに、貫通孔70中に抜け止めピン71を挿通して、抜け止めピン71をボス部61の外側端面にワッシャ72を介して当接することで、タインバー36がタインバー枢支体35から抜けないようにすることができる。また、反対の手順をたどることで、連結用板状片52aからタインバー36を取り外すことができる。その結果、連結用板状片52aにタインバー枢支体35を介してタインバー36の側端部を簡単に着脱自在に取り付けることができる。
Therefore, the connecting bolt 63 is inserted into the aligned bolt holes 52c and 62a from the outside and the nut 64 is screwed to the tip of the connecting bolt 63, so that the side end of the tine bar 36 is attached to the connecting plate-like piece 52a. The inserted tine bar pivot 35 can be attached. At this time, a through hole 70 is formed in a side end portion of the tine bar 36 in a direction perpendicular to the axis of the tine bar 36. The side end portion of the tine bar 36 is inserted into the boss portion 61 of the tine bar pivotal support body 35 so that the boss The through hole 70 is disposed outward from the outer end surface of the portion 61, and the retaining pin 71 is inserted into the through hole 70, and the retaining pin 71 is applied to the outer end surface of the boss portion 61 via the washer 72. By making contact, the tine bar 36 can be prevented from coming off the tine bar pivot 35. Moreover, the tine bar 36 can be removed from the connecting plate-like piece 52a by following the reverse procedure. As a result, the side end portion of the tine bar 36 can be easily and detachably attached to the connecting plate-like piece 52 a via the tine bar pivotal support 35.
しかも、連結用板状片52aにタインバー配置用凹部52bを介してタインバー枢支体35を側方から連結することで、回転支持体34の周端面から放射線方向に取付部品等による突起状部が形成されるのを回避することができる。そのため、回転支持体34に穀稈が突起状部に引っ掛って、刈取効率を低減させるという不具合が発生するのを防止することができる。
Moreover, by connecting the tine bar pivotal support body 35 to the connecting plate-like piece 52a from the side via the tine bar disposition recess 52b, the protrusions such as attachment parts are formed in the radial direction from the peripheral end surface of the rotary support 34. It can be avoided that it is formed. Therefore, it is possible to prevent the occurrence of a problem that the cedar is caught on the protrusions on the rotary support 34 and the cutting efficiency is reduced.
また、連結用板状片52aの外側面は、スポーク部54や連結部55の外側面に対して内側方に位置する段付き凹状面となしており、かかる連結用板状片52aの外側面にタインバー枢支体35を左右重合状態に連結しているため、回転支持体34の放射線方向はもとより、回転支持体34の外側方にも取付部材等が大きく張り出さないようにして、これらに植立穀稈が引っ掛かるのを回避することができる。
Further, the outer surface of the connecting plate-like piece 52a is a stepped concave surface located inward with respect to the outer surfaces of the spokes 54 and the connecting portion 55, and the outer surface of the connecting plate-like piece 52a. Since the tine bar pivot support 35 is connected in the left-right superposition state, the mounting member or the like does not protrude greatly on the outer side of the rotation support 34 as well as the radiation direction of the rotation support 34. It is possible to avoid the planted cereal from being caught.
(タイン37の取付構造)
タインバー36にはタイン37を1本ずつ着脱自在に取り付けるようにしている。すなわち、タイン37は、図16~図22に示すように、穀稈に作用するタイン本片80と、タイン本片80の基端部(上端部)80aを伸延させて弦巻状に屈曲形成したコイル部形成片81と、コイル部形成片81から延設してタインバー36の周面に嵌合してタイン本片80の姿勢を保持する凹状の嵌合片82と、嵌合片82に延設してタインバー36に形成された係止孔73に抜き差し自在に挿入して係止する係止片83とを、バネ鋼鋼材である一本の丸棒材を屈曲させて一体的に形成している。 (Tine 37 mounting structure)
Atine 37 is detachably attached to the tine bar 36 one by one. That is, as shown in FIGS. 16 to 22, the tine 37 is formed by bending the tine piece 80 acting on the cereal and the base end portion (upper end portion) 80a of the tine piece 80 so as to be bent into a string winding shape. The coil portion forming piece 81, a concave fitting piece 82 that extends from the coil portion forming piece 81 and fits to the peripheral surface of the tine bar 36 to maintain the posture of the tine main piece 80, and extends to the fitting piece 82 And a locking piece 83 that is inserted and locked in a locking hole 73 formed in the tine bar 36 so as to be freely inserted and removed, and is formed integrally by bending a single round bar material made of spring steel. ing.
タインバー36にはタイン37を1本ずつ着脱自在に取り付けるようにしている。すなわち、タイン37は、図16~図22に示すように、穀稈に作用するタイン本片80と、タイン本片80の基端部(上端部)80aを伸延させて弦巻状に屈曲形成したコイル部形成片81と、コイル部形成片81から延設してタインバー36の周面に嵌合してタイン本片80の姿勢を保持する凹状の嵌合片82と、嵌合片82に延設してタインバー36に形成された係止孔73に抜き差し自在に挿入して係止する係止片83とを、バネ鋼鋼材である一本の丸棒材を屈曲させて一体的に形成している。 (
A
タイン本片80は上下方向に伸延させて形成するとともに、下部を前方に凸状(「く」の字状)に折曲させて形成している。かかるタイン本片80はタインバー36から鉛直下方向に垂下させた姿勢が保持されるようにして、タイン本片80が植立穀稈をプラットフォーム21内に掻き込み作用するようにしている。
The tine main piece 80 is formed by extending in the vertical direction, and the lower part is formed by bending forward into a convex shape ("<" shape). The tine main piece 80 maintains a posture in which the tine main piece 80 hangs vertically downward from the tine bar 36 so that the tine main piece 80 acts to drive the planted cereal into the platform 21.
コイル部形成片81は、タイン本片80の基端部(上端部)80aを前上方に向けて伸延させるとともに、タイン本片80の基端部80aよりも前方位置にて二重リングの弦巻状に屈曲させて形成している。二重リングの内径はタインバー36の外径W1と略同径に形成している(図25参照)。コイル部形成片81は、植立穀稈に前方から後方に掻込作用するタイン本片80の基端部80aに一体成形して、植立穀稈により後方から前方へ反作用Fを受けるタイン本片80が垂下姿勢を保持するように弾性付勢している。
The coil portion forming piece 81 extends the base end portion (upper end portion) 80a of the tine main piece 80 toward the front upper side, and at the front position of the base end portion 80a of the tine main piece 80, a double ring string winding It is bent in a shape. The inner diameter of the double ring is substantially the same as the outer diameter W1 of the tine bar 36 (see FIG. 25). The coil portion forming piece 81 is integrally formed with the proximal end portion 80a of the tine main piece 80 that acts on the planted cereal from the front to the rear, and receives the reaction F from the rear to the front by the planted cereal. The piece 80 is elastically biased so as to maintain the hanging posture.
嵌合片82は、後方へ膨出する半円弧状に屈曲させて形成している。つまり、タイン本片80の基端部80a位置から上方へ伸延させるとともに、タインバー36の背面(後半部周面)に沿う湾曲状に伸延させ、さらに、その先端部82aをタイン本片80の基端部80a位置よりもやや前方位置まで伸延させている。そして、嵌合片82の先端部82aとコイル部形成片81の上端部81aとにより嵌合開口部84を形成している。ここで、図25に示すように、嵌合開口部84の開口幅W2はタインバー36の外径W1以下に形成するとともに、嵌合片82の半円弧径W3はタインバー36の外径W1以上に形成している。
The fitting piece 82 is bent and formed in a semicircular arc shape that bulges backward. That is, the tine main piece 80 is extended upward from the position of the base end portion 80 a of the tine piece 80, and is extended in a curved shape along the back surface (second half peripheral surface) of the tine bar 36. It is extended to a position slightly ahead of the position of the end 80a. A fitting opening 84 is formed by the tip end portion 82 a of the fitting piece 82 and the upper end portion 81 a of the coil portion forming piece 81. Here, as shown in FIG. 25, the opening width W2 of the fitting opening 84 is formed to be equal to or smaller than the outer diameter W1 of the tine bar 36, and the semicircular arc diameter W3 of the fitting piece 82 is equal to or larger than the outer diameter W1 of the tine bar 36. Forming.
このようにして、嵌合片82は、タインバー36の後方から、つまり、タイン37が植立穀稈により後方から前方へ反作用Fを受ける方向(穀稈に掻込作用する方向とは反対方向)からタインバーの周面に嵌合させるようにしている。この際、嵌合開口部84の開口幅W2はタインバー36の外径W1以下に形成している。そのため、バネ鋼鋼材により成形している嵌合片82の先端部82aとコイル部形成片81の上端部81aの弾性付勢力に抗して嵌合開口部84をタインバー36の外径と同径となるまで開口させることで、タインバー36に嵌合片82を後方から嵌合させるとともに、嵌合開口部84によるタインバー36を上下方向から挟持付勢することができる。したがって、タインバー36に嵌合片82を堅実に嵌合させて、同状態に保持させることができる。
Thus, the fitting piece 82 is the direction in which the tine 37 receives the reaction F from the rear to the front by the planted culm (the direction opposite to the direction in which the tine 37 is squeezed). It is made to fit on the peripheral surface of the tine bar. At this time, the opening width W <b> 2 of the fitting opening 84 is formed to be equal to or smaller than the outer diameter W <b> 1 of the tine bar 36. Therefore, the fitting opening 84 has the same diameter as the outer diameter of the tine bar 36 against the elastic biasing force of the tip end portion 82a of the fitting piece 82 and the upper end portion 81a of the coil portion forming piece 81 formed of spring steel. Thus, the fitting piece 82 can be fitted to the tine bar 36 from the rear, and the tine bar 36 by the fitting opening 84 can be clamped and urged from above and below. Therefore, the fitting piece 82 can be firmly fitted to the tine bar 36 and held in the same state.
係止片83は、嵌合片82の先端部82aを同一平面内で後方へUターンさせるように湾曲状に伸延させるとともに、鉛直下方へ略直角に折曲させて、先端部がコイル部形成片81の上端部81a側方位置まで達するように、直状に伸延させて形成している。ここで、係止片83とタイン本片80の基端部(上端部)80aは、図17に示すように、側面視にて略同一軸芯線上に配置している。そして、係止片83は、嵌合片82の嵌合方向(後方から前方へ略水平に嵌合させる方向)とは略直交する上方から、タインバー36に形成された係止孔73に挿入して係止されるようにしている。
The locking piece 83 extends in a curved shape so that the distal end portion 82a of the fitting piece 82 is U-turned backward in the same plane, and is bent vertically downward substantially perpendicularly so that the distal end portion forms a coil portion. The piece 81 is formed to extend straight so as to reach the side position of the upper end 81a. Here, the base end portion (upper end portion) 80a of the locking piece 83 and the tine main piece 80 is disposed on substantially the same axial line in a side view as shown in FIG. Then, the locking piece 83 is inserted into the locking hole 73 formed in the tine bar 36 from above, which is substantially perpendicular to the fitting direction of the fitting piece 82 (the direction in which the fitting piece 82 is fitted substantially horizontally from the rear to the front). To be locked.
このようにタイン37を形成することで、仮にタイン37が圃場を引っ掻いた際にも、タイン37への荷重(反作用F)は嵌合片82の嵌合方向に作用するため、嵌合片82はタインバー36から外れる虞がない。そして、バネ鋼鋼材性の嵌合片82によるタインバー36への嵌合を堅実にして、同状態を保持させることができるため、タイン37の姿勢保持と、タイン37による穀稈への掻き込み効率を良好に確保することができる。
By forming the tine 37 in this manner, even when the tine 37 scratches the field, the load (reaction F) on the tine 37 acts in the fitting direction of the fitting piece 82. There is no risk of detachment from the tine bar 36. And since the fitting to the tine bar 36 by the spring steel material fitting piece 82 can be made steady and the same state can be maintained, the posture maintenance of the tine 37 and the scraping efficiency of the tine 37 into the culm Can be secured satisfactorily.
次に、タインバー36にタイン37を取り付ける方法について、図23及び図24を参照しながら説明する。
Next, a method for attaching the tine 37 to the tine bar 36 will be described with reference to FIGS.
図23及び図24(a)に示すように、係止孔73に係止片83を上方から挿入する。この際、コイル部形成片81はタインバー36の後下方に配置する。つまり、嵌合開口部84がタインバー36の軸線方向(左右方向)に開口するように位置させる。
23 and FIG. 24 (a), the locking piece 83 is inserted into the locking hole 73 from above. At this time, the coil portion forming piece 81 is disposed below the tine bar 36. That is, the fitting opening 84 is positioned so as to open in the axial direction (left-right direction) of the tine bar 36.
続いて、図23及び図24(b)に示すように、上下方向に軸線を向けている係止片83を中心に、コイル部形成片81を前方へ90℃回転させる。この際、嵌合開口部84がタインバー36の後半部周面に弾性付勢状態にて嵌合されるため、係止片83が上方へ抜けるのを規制することができる。
Subsequently, as shown in FIG. 23 and FIG. 24 (b), the coil portion forming piece 81 is rotated forward by 90 ° about the locking piece 83 whose axis is directed in the vertical direction. At this time, since the fitting opening 84 is fitted to the peripheral surface of the rear half of the tine bar 36 in an elastically biased state, the locking piece 83 can be prevented from coming out upward.
このように、タインバー36にタイン37を簡単かつ堅実に取り付けることができる。また、反対に手順を辿ることで、タインバー36からタイン37を簡単に取り外すことができる。この際、ボルト・ナット等の取り付け具は必要としない。
Thus, the tine 37 can be easily and firmly attached to the tine bar 36. On the other hand, the tine 37 can be easily removed from the tine bar 36 by following the procedure. At this time, attachments such as bolts and nuts are not required.
次に、タインバー36へのタイン37の取付位置について説明するが、その取付位置はタイン37と刈刃装置22の穀稈案内片91bとの相対関係に係わるため、便宜上、まず刈刃装置22の構成を説明する。
Next, the attachment position of the tine 37 to the tine bar 36 will be described. Since the attachment position is related to the relative relationship between the tine 37 and the grain guide piece 91b of the cutting blade device 22, the cutting blade device 22 is first described for convenience. The configuration will be described.
刈刃装置22は、図3及び図5に示すように、プラットフォーム21の前下端縁部にその左右幅前幅にわたって伸延する刈刃台90を取り付け、刈刃台90に多数の受刃91を前方(機体の前進方向)へ向けて突定し、受刃91上にて左右方向に伸延させて前端縁部を鋸刃状に形成した刈刃92を左右方向に一定幅にて往復摺動させることで、刈刃92と受刃91の相互作用にて植立穀稈の株元部が切断されるように構成している。受刃91は、基端部(後端部)の受刃本片91aと先端部(前端部)の穀稈案内片91bとから前後方向に伸延させ、かつ、前方へ先細り状に形成している。そして、多数の受刃91は、それぞれ左右幅方向に一定の間隔を開けて配置して、左右に隣接する受刃91,91の穀稈案内片91b,91b間に植立穀稈の株元部を案内して、その株元部を刈刃92により切断するようにしている。受刃本片91aには摺動溝(図示せず)を形成しており、摺動溝中を刈刃92が横断状に摺動するようにしている。
As shown in FIGS. 3 and 5, the cutting blade device 22 has a cutting blade base 90 extending to the front lower end edge of the platform 21 extending over the front width of the left and right widths, and a plurality of receiving blades 91 are attached to the cutting blade base 90. A cutting blade 92, which projects forward (in the forward direction of the machine body) and extends in the left-right direction on the receiving blade 91 and has a front edge formed in a saw blade shape, reciprocally slides with a constant width in the left-right direction. By doing so, the planted portion of the planted cereal cocoon is cut by the interaction between the cutting blade 92 and the receiving blade 91. The receiving blade 91 extends from the receiving blade main piece 91a at the base end portion (rear end portion) and the culm guide piece 91b at the distal end portion (front end portion) in the front-rear direction, and is tapered forward. Yes. And many receiving blades 91 are arrange | positioned at predetermined intervals in the left-right width direction, respectively, and the planted grain culm stock between the culm guide pieces 91b, 91b of the receiving blades 91, 91 adjacent to the left and right The stock is guided by the cutting blade 92. A sliding groove (not shown) is formed in the receiving blade main piece 91a, and the cutting blade 92 slides in a transverse manner in the sliding groove.
タイン37のタイン本片80は、平面図である図5に示すように、左右に隣接する穀稈案内片91b,91b間の略中央部位置を示す仮想線Kと平面視で整合する位置に配置している。しかも、各タインバー36には多数のタイン37を左右方向に間隔を開けて取り付けるとともに、隣接するタインバー36同士に取り付けたタイン37同士は半ピッチずつずらして取り付けている。つまり、左右に隣接する穀稈案内片91b,91b同士の間隔をピッチPとすると、各タインバー37に多数取り付けるタイン37同士(具体的にはタイン本片80同士)は2つ分のピッチPを開け、隣接するタインバー37に取り付けるタイン37(具体的にはタイン本片80)相互の間隔は1つ分のピッチPを開けるようにしている。
As shown in FIG. 5, which is a plan view, the tine main piece 80 of the tine 37 is aligned with a virtual line K indicating a substantially central position between the grain guide pieces 91 b and 91 b adjacent to the left and right in a plan view. It is arranged. In addition, a large number of tines 37 are attached to each tine bar 36 at intervals in the left-right direction, and the tines 37 attached to the adjacent tine bars 36 are attached with a shift of a half pitch. That is, if the spacing between the left and right cereal guide pieces 91b, 91b is a pitch P, the tines 37 (specifically, the tine main pieces 80) attached to each tine bar 37 have a pitch P of two. The tines 37 (specifically, the tine main piece 80) attached to the adjacent tine bars 37 are opened at a pitch P of one.
このように、各タイン37を左右に隣接する穀稈案内片91b,91b間の略中央部上方に配置しているため、各タイン37による植立穀稈の掻き込みが円滑かつ堅実になされる。そして、後続の刈刃装置22による植立穀稈の株元部の切断、さらには掻込オーガ25による掻込・搬送の各作業がスムーズになされる。
In this way, since each tine 37 is disposed substantially above the middle portion between the left and right adjacent grain guide pieces 91b, 91b, the vine 37 is scraped smoothly and firmly by each tine 37. . Then, the cutting of the planted cereal culm by the subsequent cutting blade device 22, and further, each of the scraping and transporting operations by the scraping auger 25 is performed smoothly.
