以下、本発明の実施例を図面に基づいて具体的に説明する。
まず、1実施態様として汎用コンバインの構成例について説明する。
まず、図1〜図2に示す汎用コンバインの構成について述べる。
Embodiments of the present invention will be specifically described below with reference to the drawings.
First, a configuration example of a general purpose combine will be described as one embodiment.
First, the configuration of the general-purpose combine shown in FIGS.
走行クロ−ラ1を具備する車体2上には、前部に昇降可能な刈取部3を、後部にスレッシャ−タイプの脱穀部4を搭載している。刈取部3のフイ−ダハウスの横側部には運転操作部5及び運転席6が設置され、その後方にはグレンタンク7が装備されている。   On the vehicle body 2 having the traveling crawler 1, a mowing part 3 that can be moved up and down is mounted on the front part, and a threshing type threshing part 4 is mounted on the rear part. A driving operation unit 5 and a driver's seat 6 are installed on the side of the feeder house of the mowing unit 3, and a Glen tank 7 is installed behind the driving operation unit 5.
刈取部3は、立毛するひまわり茎稈を後方に掻き寄せる掻込リ−ル10と、茎稈上部を切断する第1刈刃11と、第1刈刃11で切断後の茎稈上部を受け入れて横送りした後に後方へ掻き込む掻込オーガ12と、掻込オ−ガ12によって掻き込まれた茎稈上部を受け入れて後方の脱穀部4に揚上搬送するフィードコンベア13と、前記第1刈刃11及び掻込オーガ12の後方下方に設置されて茎稈の株元側を切断処理する第2刈刃14を備えた構成としている。   The cutting part 3 receives a scraping reel 10 that rakes up the raised sunflower stalk, a first cutting blade 11 that cuts the top of the stalk, and an upper part of the stalk that has been cut by the first cutting blade 11. The feed auger 12 that receives the upper part of the shoots scraped by the scraper auger 12 and lifts and conveys it to the rear threshing unit 4; It is set as the structure provided with the 2nd cutting blade 14 which is installed in the back lower part of the cutting blade 11 and the taking-in auger 12, and cuts the stock side of the stalk.
前記第1刈刃11の前方には、左右の分草具8,8間において、圃場の立毛茎稈を導入して後方に誘導搬送する複数条の誘導搬送経路15をもつ誘導搬送装置9をその前部が前方下方に位置し、後部が後方上方に配置した前記第1刈刃11の近傍に位置するよう斜設している。そして、この誘導搬送装置9は、複数の搬送無端帯9a〜9eからなり、それぞれ誘導搬送経路15を形成すべく前後の横軸16a(搬送駆動軸),16b(搬送従動軸)回りに券回し、所定間隔置きに配設した搬送ラグ17によって複数のひまわり茎稈を誘導しながら搬送できるように構成している。   In front of the first cutting blade 11, there is a guide transport device 9 having a plurality of guide transport paths 15 for introducing a raised hairbrush in the field between the left and right weeding tools 8, 8 to guide and transport backward. The front portion is located obliquely so as to be located in the vicinity of the first cutting blade 11 disposed at the front lower side and the rear portion disposed at the rear upper side. The guide transport device 9 is composed of a plurality of transport endless belts 9a to 9e, each of which is wound around the front and rear horizontal axes 16a (transport drive shaft) and 16b (transport driven shaft) to form the guide transport path 15. The plurality of sunflower stalks can be guided and conveyed by the conveying lugs 17 arranged at predetermined intervals.
なお、誘導搬送装置9は、始端側が終端側の搬送駆動軸16aを支点として上下動するように構成してあり、また、実施例では無端帯の上面にひまわりの花托部を載せて搬送できるように構成してあると共に、各無端帯間の誘導搬送経路15部には茎稈を案内する保持ガイド部材18aを設けて前記無端帯のガイドレール18bと一体化した構成としている。これによれば、上部花托側を無端帯で支えながら、下方の茎稈を保持ガイド部材18aで一定幅に案内するので、茎稈の姿勢が乱れにくくなり、安定した搬送性能が得られる。また、無端帯9a〜9eの非作用側にあって、茎稈を第1刈刃11に案内する保持ガイド部材18a,18a間の誘導搬送経路幅Dを、前記第1刈刃11の刈刃フィンガ24,24間より狭くすることによって、花托部下方の茎稈を確実に第1刈刃のフィンガー間に送りこむことができる。更に、搬送終端側の搬送ローラ23においても、刈刃フィンガ24,24の1ピッチ間内に収めるように構成することで、隣接する搬送経路は広く確保でき、花托の詰まりなどが少なくなる。   In addition, the guide conveyance device 9 is configured such that the start end side moves up and down with the conveyance drive shaft 16a at the end side as a fulcrum, and in the embodiment, the sunflower flower portion can be carried on the upper surface of the endless belt. In addition, a holding guide member 18a for guiding the pedicles is provided in the guide conveyance path 15 between the endless belts so as to be integrated with the guide rail 18b of the endless belt. According to this, while supporting the upper floret side with the endless belt, the lower pedicle is guided to the fixed width by the holding guide member 18a, so that the posture of the pedicle becomes difficult to be disturbed, and stable conveying performance is obtained. Further, the guide conveyance path width D between the holding guide members 18a, 18a, which is on the non-acting side of the endless belts 9a to 9e and guides the stems to the first cutting blade 11, is defined as the cutting blade of the first cutting blade 11. By making it narrower than between the fingers 24, 24, the stems below the flower buds can be reliably fed between the fingers of the first cutting blade. Further, the conveyance roller 23 on the conveyance end side is also configured to be accommodated within one pitch of the cutting blade fingers 24, 24, so that an adjacent conveyance path can be secured widely, and clogging of florets is reduced.
各搬送無端帯9a〜9eの前端部には、該無端帯の回転部を左右外側から挟むように先端を先細り状に形成した分草杆25を設けると共に、搬送ガイドレール18bの両側に連結保持させ(図5参照)た構成としている。各分草杆により、多様な方向に向いた茎稈でも誘導搬送経路内に確実に分草案内することができ、搬送ガイドレールに連結するので、レール自体の強度アップも図ることができる。 前記掻込オーガ12の前側位置には、第1刈刃11で切断後の茎稈を既刈地側に向けて横搬送する茎稈横送り手段20が設けられている。この茎稈横送り手段20は、螺旋軸21と横送り螺旋22とからなり、第1刈刃11の下方で収集テーブル19の前部下側において前記掻込オーガ12軸と平行する横方向に軸受して装備し、前記第2刈刃14よりも前方上方位置に配置している。従って、この茎稈横送り螺旋22は、茎稈誘導搬送装置9の誘導搬送経路15内を後方に搬送されながら、上部の花托が切断された茎稈を、未刈地側とは反対の既刈地側に向けて横送りすることによって、ひまわり茎稈が一箇所に滞留することが避けられ、連続した刈取作業がスムーズに行える。また、横送りされる茎稈は、未刈地側の未刈稈とは遠く離れた既刈地側に送られるので、次行程での刈取作業時にそれが邪魔になることがなく、作業能率を高めることができる。   At the front end portion of each transport endless belt 9a-9e, there is provided a weed tub 25 having a tip tapered so as to sandwich the rotating portion of the endless belt from the left and right outer sides, and connected and held on both sides of the transport guide rail 18b. (See FIG. 5). Each weed culm can reliably guide the weeds even in various directions into the guided transport path and is connected to the transport guide rail, so that the strength of the rail itself can be increased. At the front side position of the scraping auger 12, a stalk lateral feed means 20 is provided for laterally transporting the stalk after cutting with the first cutting blade 11 toward the already-cut ground. The stalk lateral feed means 20 is composed of a spiral shaft 21 and a lateral feed spiral 22, and is bearing in a lateral direction parallel to the auger 12 axis below the first cutting blade 11 and below the front portion of the collection table 19. The second cutting blade 14 is disposed at a front upper position. Therefore, the pedicle lateral feed spiral 22 is used to transfer the pedicles from which the upper florets have been cut while being conveyed backward in the guided conveyance path 15 of the pedicle guiding and conveying device 9 to the side opposite to the uncut ground side. By laterally feeding toward the cutting area, the sunflower stalk can be prevented from staying in one place, and continuous cutting operations can be performed smoothly. In addition, since the stalks that are fed sideways are sent to the already-cut area, which is far away from the uncut area on the uncut area, it does not get in the way when cutting in the next stroke. Can be increased.
また、前記横送り螺旋22において、図7及び図8に示すように、螺旋翼板22aの外周には、その送り面側において係止突起22bが形成されるように逆L字形の螺旋翼板を構成することで、茎稈に螺旋係止突起が食い付くようになり、送り効果が的確に発揮されて、茎稈の切断作用がスムーズに行なえる。   Further, in the transverse feed spiral 22, as shown in FIGS. 7 and 8, an inverted L-shaped spiral blade is formed so that a locking projection 22 b is formed on the outer periphery of the spiral blade 22 a on the feed surface side. As a result of the construction, the spiral locking projection comes to bite into the pedicle, the feeding effect is accurately exhibited, and the cutting action of the pedicle can be performed smoothly.
収集テーブル19上に受け入れられたひまわり茎稈上部の花托部は、掻込オーガ12の螺旋部12aによって未刈地側一側に横送りされたのち、掻込フィンガー12bによって後方に掻き込まれ、フィードコンベア13の始端に受け継がれるようになっている。   The flower part of the upper part of the sunflower stalk received on the collection table 19 is laterally fed to one side of the uncut area by the spiral part 12a of the picking auger 12, and is then swept backward by the picking finger 12b. It is inherited by the start end of the feed conveyor 13.
次に、刈取部の伝動構成について説明すると、エンジンEから動力伝達される刈取入力軸30には、フィードコンベア13を架設して該コンベアを回転駆動するように連動構成している。刈取入力軸30からカウンタ軸31を介して第1刈刃11の刈刃駆動軸32をベルト33によって回転駆動すべく連動構成してあり、そして、螺旋軸21へは刈刃駆動軸32からベルト34を介して駆動するように連動構成している。また、誘導搬送装置9への搬送駆動軸16aは、前記カウンタ軸31から第2カウンタ軸35、ベルト36等を介して回転駆動し、掻込オーガ12軸は、カウンタ軸31からベルト37を介して駆動され、掻込リール10軸は、第1・第2ベルト38,39を介して駆動されるようになっている。そして、これら各部への伝動装置は、刈取部一側の刈取側板に集中的に配置した構成としている。   Next, the transmission configuration of the cutting unit will be described. The cutting input shaft 30 to which power is transmitted from the engine E is linked to the feed conveyor 13 so that the conveyor is rotationally driven. The cutting blade drive shaft 32 of the first cutting blade 11 is interlocked to be rotationally driven by the belt 33 from the cutting input shaft 30 through the counter shaft 31, and the spiral shaft 21 is connected to the belt from the cutting blade drive shaft 32. 34 is configured to be driven via 34. Further, the transport drive shaft 16a to the guide transport device 9 is rotationally driven from the counter shaft 31 through the second counter shaft 35, the belt 36, etc., and the take-in auger 12 shaft is driven from the counter shaft 31 through the belt 37. The take-up reel 10 axis is driven via the first and second belts 38 and 39. And the transmission apparatus to these each part is set as the structure arrange | positioned intensively on the cutting side board of the cutting part one side.
脱穀部4は、扱室46内に扱胴47を前後方向に架設し、扱室の下壁に受網48を張設し、扱室の下方には唐箕49や揺動選別装置を備える選別室を設けた構成としている。
図10において、第2刈刃(円盤刈刃)14は、後端側を車体2の前部に回動自在に枢着したセカンドモアフレーム50に、揺動リンク51を介して取り付けられた刈取支持台52に軸架してあり、駆動モータ53によって駆動される構成としている。吊上ロッド54は、前記セカンドモアフレーム50の中間部位に下側から係合するストッパー55を設け、その下端部を前記刈取支持台52に回動可能な関節状態に連結し、上部を昇降作動杆56に長孔57と接合ピン58によって吊り下げ可能に連結した構成としている。
In the threshing section 4, a handling cylinder 47 is installed in the handling chamber 46 in the front-rear direction, a receiving net 48 is stretched on the lower wall of the handling chamber, and the sorting is provided with the Kara 49 and the swing sorting device below the handling chamber. The room is provided.
In FIG. 10, a second cutting blade (disk cutting blade) 14 is a cutting blade attached via a swing link 51 to a second more frame 50 pivotally attached to the front portion of the vehicle body 2 at the rear end side. It is mounted on a support base 52 and driven by a drive motor 53. The lifting rod 54 is provided with a stopper 55 that engages from the lower side at an intermediate portion of the second more frame 50, its lower end portion is connected to the cutting support base 52 in a jointable state, and the upper portion is moved up and down. The rod 56 is connected to the long hole 57 and the joining pin 58 so as to be suspended.
そして、ガススプリング60は、上部を昇降モータ61に減速ギヤ機構62を介して接続している回動アーム63に連結し、下部を昇降作動杆64の後端部に連結構成している。しかして、第2刈刃14は、昇降モータ61を正転方向に駆動すると、減速ギヤ機構62、回動アーム63、ガススプリング60、昇降作動杆56、ストッパー55、セカンドモアフレーム50、刈取支持台52が一体的に作動して上昇し、収納位置に達する。そして、第2刈刃14は、昇降モータ61を逆転方向に駆動すれば、作業位置に下降することができる。   The upper part of the gas spring 60 is connected to the rotating arm 63 connected to the lifting motor 61 via the reduction gear mechanism 62, and the lower part is connected to the rear end of the lifting operation rod 64. Thus, when the lifting / lowering motor 61 is driven in the forward rotation direction, the second cutting blade 14 has a reduction gear mechanism 62, a rotating arm 63, a gas spring 60, a lifting / lowering rod 56, a stopper 55, a second more frame 50, and a cutting support. The base 52 operates integrally and rises to reach the storage position. And the 2nd cutting blade 14 can be lowered | hung to a working position, if the raising / lowering motor 61 is driven to a reverse rotation direction.
図11、図12において、刈取部3の未刈地側の一側部には、未刈側分草具8(左側)の近くから前方に向けて側面視略L字形に屈曲形成する分草ガイド杆26を突設して、未刈側の茎稈を機体外側方へ分草案内するように構成している。従って、この分草ガイド杆により、機体側に倒れかかってくる未刈茎稈を機体でひっかけることなく外側方へ押し出すことができるため、刈取作業がスムーズに行え、連続作業が可能となる。また、左右両側の分草具8,8と、搬送無端帯9a,9eの分草杆25,25との間には、茎稈を機体外側方と誘導搬送経路内とに振り分けて誘導案内する誘導杆27,27を設けている。   In FIG. 11 and FIG. 12, a weed that is bent and formed in a substantially L-shaped side view from the vicinity of the uncut-side weeding tool 8 (left side) to the one side of the uncut-cutting side of the cutting unit 3. A guide rod 26 is provided so as to guide the uncut-side stem rod toward the outside of the fuselage. Therefore, this weed guide rod can push the uncut stem culm that falls down on the side of the machine body outward without being caught by the machine body, so that the cutting operation can be carried out smoothly and continuous work can be performed. Further, between the right and left weeding tools 8 and 8 and the weed stubs 25 and 25 of the transport endless bands 9a and 9e, the stalks are distributed and guided to the outside of the machine body and the guide transport path. Guide rods 27 and 27 are provided.
更に、図11〜図13において、誘導搬送装置9の終端部が収集テーブル19の上方に臨むように配した構成のものにあって、前記収集テーブル19の前縁と搬送無端帯9a〜9eの下部非作用側間には、塞ぎ板28を立設すると共に、搬送無端帯側からは前記塞ぎ板28にかぶるように巻付防止板29を垂下させて設けている。誘導搬送装置を終端側を支点として上下動させる構成のものにあっても、上記構成により、花托のテーブル内へのスムーズな案内落下が期待でき、茎稈などの巻き付きも回避することができる。なお、上記構成に加えて、図14に示すように、搬送無端帯9a〜9e間の全幅に亘り、各無端帯終端側から塞ぎ板28に重なるようにゴム状板材45を設けるようにしておけば、誘導搬送装置を上下に揺動させて搬送終端と塞ぎ板との間の隙間が変化しても、ゴム状板材が追従し、隙間を全面的に塞ぐので、花托のみならず、脱粒した種子も確実にテーブルに投入されヘッドロスが大幅に減少する。   Further, in FIGS. 11 to 13, the guiding and conveying device 9 is arranged so that the terminal portion thereof faces the upper side of the collecting table 19, and the front edge of the collecting table 19 and the conveying endless bands 9 a to 9 e are arranged. Between the lower non-acting sides, a closing plate 28 is erected, and an anti-winding plate 29 is suspended from the endless belt side so as to cover the closing plate 28. Even in the configuration in which the guide conveyance device is configured to move up and down with the end side as a fulcrum, the above configuration can be expected to smoothly guide and drop the florets into the table, and the wrapping of stems and the like can be avoided. In addition to the above configuration, as shown in FIG. 14, a rubber plate 45 may be provided so as to overlap the closing plate 28 from the end of each endless band over the entire width between the transport endless bands 9a to 9e. For example, even if the gap between the conveyance end and the closing plate is changed by swinging the guide transfer device up and down, the rubber-like plate material follows and closes the gap entirely, so that not only the flower buds but also the grains are shattered Seeds are also reliably placed on the table, greatly reducing head loss.
図15、図16において、収集テーブル19の下面側前部から第2刈刃14に向けて茎稈案内棒66を設けることにより、茎稈を刈刃に向けて確実に誘導案内でき、切断作用がスムーズに行えるようにしている。   15 and 16, by providing the stalk guide rod 66 from the lower front side of the collection table 19 toward the second cutting blade 14, the stalk can be reliably guided and guided toward the cutting blade, and the cutting action is achieved. Can be done smoothly.
また、円盤刈刃14を支持するセカンドモアフレーム50には、刈刃前方から刈刃上まで茎稈を案内するガイドプレート67を該フレーム50や駆動モータ53を覆うように起立させて設けている。これによれば、茎稈を刈刃上まで案内するので、切断作用が確実に行われると共に、フレームや駆動モータに茎稈がひっかかることがなく、茎稈の流れがスムーズになり、詰まりなどのトラブルが解消される。   In addition, the second mower frame 50 that supports the disc cutting blade 14 is provided with a guide plate 67 that guides the pedicle from the front of the cutting blade to the top of the cutting blade so as to cover the frame 50 and the drive motor 53. . According to this, since the pedicle is guided to the cutting blade, the cutting action is surely performed, the pedicle is not caught on the frame or the drive motor, the flow of the pedicle becomes smooth, clogging, etc. Trouble is solved.
図17、図18に示す茎稈案内棒66は、後端が刈刃14上まで延出されて交叉している点で、図15、図16の実施例とは異なるが、切断効果がより高められる。また、図17、図18のガイドプレート67は、後端側が刈刃14の中心側に向けて傾斜しているのに対し、図15、図16では前後方向に平行状である点で異なるが、いずれの実施例も切断作用は効果的に行うことができる。   17 and 18 differs from the embodiment of FIGS. 15 and 16 in that the rear end extends to the cutting blade 14 and crosses, but the cutting effect is more effective. Enhanced. Further, the guide plate 67 in FIGS. 17 and 18 is different in that the rear end side is inclined toward the center side of the cutting blade 14 whereas the guide plate 67 is parallel to the front-rear direction in FIGS. In any of the embodiments, the cutting action can be effectively performed.
図19、図20に示す実施例では、セカンドモアフレーム50の先端(前端)部に、平面視で先端側ほど横外側方に広がる案内体68を設けることによって、茎稈の導入範囲が拡がり、前方から導入されてくる茎稈がセカンドモアフレームとの干渉を避けることになり、刈刃側へスムーズに案内されることになって、刈り残しを未然に防止することができる。   In the embodiment shown in FIGS. 19 and 20, the introduction range of the pedicles is expanded by providing a guide body 68 that spreads laterally outward toward the distal end side in a plan view at the distal end (front end) portion of the second more frame 50, The stem stem introduced from the front avoids interference with the second more frame, and is smoothly guided to the cutting blade side, so that uncut cutting can be prevented in advance.
上下に昇降可能な第2刈刃14は、例えば、脱穀クラッチ又は刈取クラッチを「OFF」及び後進スイッチ「ON」の時、第2刈刃が非作業位置まで上昇する最上位置収納状態となるよう連動構成しておくと、非刈取作業時や後進時には第2刈刃が最上位置に収納しているため、障害物との接触による刈刃の破損を招くことがない。   For example, when the threshing clutch or the mowing clutch is “OFF” and the reverse switch “ON”, the second cutting blade 14 that can be moved up and down is in the uppermost position storage state in which the second cutting blade rises to the non-working position. If the interlocking configuration is used, the second cutting blade is housed in the uppermost position during non-cutting operations or when moving backward, so that the cutting blade is not damaged due to contact with an obstacle.
また、図21、図22に示すように、刈取部の茎稈誘導搬送装置9の誘導搬送経路内に茎稈検出センサ70を設け、茎稈検出センサの茎稈導入検出結果により、第2刈刃14が刈取作業位置まで下降し、ある一定時間、導入茎稈を検出しない時には、第2刈刃が自動的に上昇するよう連動構成しておくと、突込みによる刈刃の破損を防止することができる。なお、本例では、センサ70が茎稈導入を検出すると、この検出結果に基づき、昇降モータ61を逆転方向に駆動して刈刃を下降させ、茎稈導入が無くなると、センサ70の非検出結果に基づき、昇降モータ61を正転方向に駆動して刈刃を上昇させる構成としている。   Further, as shown in FIGS. 21 and 22, a pedicle detection sensor 70 is provided in the guided conveyance path of the pedicle guiding and conveying device 9 of the cutting unit, and the second chopping detection result of the pedicle detection sensor determines the second cutting When the blade 14 is lowered to the cutting work position and the introduced pedicle is not detected for a certain period of time, the second cutting blade is configured to automatically move up to prevent the cutting blade from being damaged due to the rush. Can do. In this example, when the sensor 70 detects the introduction of the stem, based on the detection result, the lifting motor 61 is driven in the reverse direction to lower the cutting blade. Based on the result, the lifting motor 61 is driven in the forward rotation direction to raise the cutting blade.
また、図23に示す実施例では、刈取部に、前方より後方ほど高位となる複数条の茎稈誘導搬送装置9と、その終端側に設けられて誘導搬送後の茎稈上部を切断する第1刈刃11を備えてあるものにおいて、複数の搬送無端帯(9a〜9e)からなる茎稈誘導搬送装置9全体を、終端側の横軸(搬送駆動軸)16aと途中部の載架レール71に沿って左右横方向にスライド移動できるように構成している。畦際や稍倒伏して畝の中央からずれた位置にある作物でも、誘導搬送部全体を左右にスライド調節することによって確実に取り込むことができ、適応性の拡大を図ることができる。   Further, in the embodiment shown in FIG. 23, a plurality of stalk guide transporting devices 9 that are higher in the rear from the front are provided in the cutting part, and the upper part of the shoots that are provided on the terminal side and that are guided and transported are cut. In the one provided with one cutting blade 11, the culm guiding and conveying device 9 including a plurality of conveying endless belts (9 a to 9 e) is divided into a lateral axis (conveying drive shaft) 16 a on the end side and a mounting rail in the middle. 71 is configured to be slidable horizontally in the horizontal direction. Even crops lying on the heel or lying down and deviating from the center of the cocoon can be reliably taken in by sliding the entire guiding and conveying section to the left and right, and the adaptability can be expanded.
更に、図24に示す実施例では、誘導搬送部9全体を、搬送無端帯9a〜9eの1組と、搬送無端帯9e〜9hの1組とからなるように左右2組に分割し、それぞれが左右方向に一体的にスライドするよう構成している。これによると、図23の実施例に増して適応性の拡大を図ることができ、搬送部の2組それぞれを畝に合わせて左と右にスライドすることにより、2畝を効率よく刈り取ることができる。   Furthermore, in the embodiment shown in FIG. 24, the entire guide transport unit 9 is divided into two sets on the left and right sides so as to be composed of one set of transport endless bands 9a to 9e and one set of transport endless bands 9e to 9h. Is configured to slide integrally in the left-right direction. According to this, it is possible to expand the adaptability as compared with the embodiment of FIG. 23, and by efficiently sliding the left and right sides of the two sets of the transporting unit according to the two sets, the two sets can be efficiently cut off. it can.
