刈取装置４は、左右方向に間隔をおいて配置した複数の分草装置７と、各分草装置７の後方に設けた複数の引起装置８等を有して構成する。引起装置８の後方には、穀稈の株元を切断する刈刃１０および刈り取った穀稈を搬送する穀稈搬送装置Ｈを設ける。穀稈搬送装置Ｈの構成は、任意であり、１１は引起装置８の後方の掻込装置、１２は株元搬送装置、１３は穂先搬送装置、１８は脱穀装置３に穀稈を供給する穀稈供給搬送装置である。
An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a body frame, 2 a traveling device, 3 a threshing device provided above the traveling device 2, 4 a reaping device, and 5 a side portion of the threshing device 3. Glen tanks, 5 are Glen tanks, and 6 is a control unit.
The reaping device 4 includes a plurality of weeding devices 7 arranged at intervals in the left-right direction, a plurality of pulling devices 8 provided at the rear of each weeding device 7, and the like. Behind the pulling device 8, there are provided a cutting blade 10 for cutting the stock of the culm and a culm conveying device H for conveying the harvested culm. The configuration of the cereal conveying device H is arbitrary, 11 is a rake device behind the pulling device 8, 12 is a stock conveying device, 13 is a tip conveying device, and 18 is a cereal that supplies cereal to the threshing device 3. It is a cocoon supply transport device
前記引起装置８は、前記掻込装置１１の前方に左右一対設ける。左右の引起装置８は、引起フレーム２０に設けた駆動輪２１と下部外側従動輪２２と下部内側従動輪２３とに引起ラグ２４を所定間隔おいて複数起伏自在に取付けた引起チェン２５を掛け回しており、これらの駆動機構の前側に引起ケース２６を設けて構成する。
前記引起装置８は、引起ラグ２４が直線的に横移動する横移動部Ｙを形成し、正面視において、前記掻込装置１１の前端部が、引起ラグ２４横移動部Ｙの外側端近傍又は内側に配置する。
即ち、前記引起装置８の下部に二つ下部外側従動輪２２と下部内側従動輪２３を設け、下部外側従動輪２２および下部内側従動輪２３とに引起ラグ２４を複数設けた引起チェン２５を巻き掛けて、二つの下部外側従動輪２２と下部内側従動輪２３の間を前記引起ラグ２４が直線的に横移動する横移動部Ｙに形成する。
A pair of left and right pulling devices 8 are provided in front of the scraping device 11. The left and right pulling devices 8 hang a pulling chain 25 in which a plurality of pulling lugs 24 are attached to a driving wheel 21, a lower outer driven wheel 22, and a lower inner driven wheel 23 provided on the pulling frame 20 at a predetermined interval. The pulling case 26 is provided on the front side of these drive mechanisms.
The pulling device 8 forms a lateral movement part Y in which the pulling lug 24 linearly moves laterally, and the front end portion of the scraping device 11 is in the vicinity of the outer end of the pulling lug 24 lateral movement part Y in the front view or Place inside.
That is, two lower outer driven wheels 22 and a lower inner driven wheel 23 are provided at the lower part of the pulling device 8, and a pulling chain 25 having a plurality of pulling lugs 24 is wound around the lower outer driven wheel 22 and the lower inner driven wheel 23. As a result, the pulling lug 24 is formed between the two lower outer driven wheels 22 and the lower inner driven wheel 23 in a laterally moving portion Y where the pulling lug 24 linearly moves laterally.
そのため、引起ラグ２４が引起ケース２６の下部を移動する際の直線移動部分を長くし、左右の引起装置８間の引起せる穀稈幅を広くしている。
前記左右一対の引起装置８の引起ラグ２４の移動軌跡より外側に前記分草装置８を設けるが、引起装置８は前記走行装置２の左右のクローラー３０より外側に位置させる。
即ち、小型のコンバインにおいては、左右のクローラー３０の轍間距離よりも刈取装置４の刈取幅が狭くなって、機体の左右両外側方に未刈り穀稈が存在する中割り作業が難しくなるが、引起装置８は前記走行装置２の左右のクローラー３０より外側に位置させ、この分草装置７が分草した穀稈を引起装置８が引き起こして刈り取り搬送できる所謂全面刈り対応構成としている。
前記引起装置８の引起ラグ２４のピッチは、前記下部外側従動輪２２と下部内側従動輪２３との間を横移動するときに、複数の引起ラグ２４が移動する構成とする。
そのため、引起ラグ２４による穀稈の引起姿勢を良好にする。
Therefore, the linear movement part when the pulling lug 24 moves in the lower part of the pulling case 26 is lengthened, and the width of the grain that can be raised between the left and right pulling devices 8 is widened.
The weeding device 8 is provided outside the movement locus of the pulling lug 24 of the pair of left and right pulling devices 8, and the pulling device 8 is positioned outside the left and right crawlers 30 of the traveling device 2.
That is, in a small combine, the harvesting width of the harvesting device 4 is narrower than the distance between the left and right crawlers 30, and it becomes difficult to perform the half-slicing operation where uncut grain culms exist on the left and right outer sides of the machine body. The pulling device 8 is positioned outside the left and right crawlers 30 of the traveling device 2, and has a so-called full-cutting configuration in which the pulling device 8 causes the pulling device 8 to cut and convey the cereals that have been weeded.
The pitch of the pulling lugs 24 of the pulling device 8 is configured such that when the lateral movement between the lower outer driven wheel 22 and the lower inner driven wheel 23 is laterally moved, the plurality of pulling lugs 24 are moved.
Therefore, the raising posture of the cereal by the raising lug 24 is made favorable.
前記掻込装置１１は、該掻込装置１１の前端部を引起装置８の背面に近づける構成とする。
即ち、掻込装置１１の掻込ラグ３５が前記引起装置８の引起フレーム２０の後方近傍を通過する構成とする。
そのため、引起装置８の引起ラグ２４が引き起こした穀稈を直ぐに掻込装置１１の掻込ラグ３５が掻き込み、穀稈の中間部が垂れ下がって、穂先が引起装置８の引起ラグ２４で扱かれて生じるヘッドロスを抑制し、また、穀稈の引き抜きを防止する。
前記引起装置８は、引起フレーム２０の基部を分草杆３６に取付杆３７を介して取付ける。この取付杆３７よりも前方位置に前記掻込装置１１の掻込ラグ３５の移動軌跡を臨ませると、掻込装置１１の作用域を引起装置８の後側に接近させられ、掻込ラグ３５は引起穀稈を掻き寄せを良好にして、搬送姿勢を良好にする。
また、掻込装置１１の掻込ラグ３５の移動軌跡は、引起装置８の下部を移動する引起ラグ２４より後方であって、引起装置８の引起フレーム２０の下部後面の延長線Ｌと略同等または前方に位置させると、掻込装置１１の作用域を引起装置８の後側に接近させられ、搬送姿勢を良好にする。
The scraping device 11 is configured to bring the front end of the scraping device 11 close to the back surface of the pulling device 8.
In other words, the scraping lug 35 of the scraping device 11 passes through the vicinity of the rear of the pulling frame 20 of the pulling device 8.
Therefore, immediately after the culm caused by the pulling lug 24 of the pulling device 8, the scraping lug 35 of the scraping device 11 rakes in, and the middle part of the gruel hangs down, and the tip is handled by the pulling lug 24 of the pulling device 8. The head loss that occurs is suppressed, and the withdrawal of cereals is prevented.
The pulling device 8 attaches the base portion of the pulling frame 20 to the weeding rod 36 via the mounting rod 37. When the movement trajectory of the scraping lug 35 of the scraping device 11 faces the front side of the mounting rod 37, the working area of the scraping device 11 is brought closer to the rear side of the pulling device 8, and the scraping lug 35 Squeezes the raised cereal meal and improves the conveying posture.
Further, the trajectory of the scraping lug 35 of the scraping device 11 is behind the pulling lug 24 that moves in the lower portion of the pulling device 8 and is substantially equal to the extension line L on the lower rear surface of the pulling frame 20 of the pulling device 8. Or if it positions ahead, the operation area of the picking-up apparatus 11 will be made to approach the rear side of the pulling apparatus 8, and a conveyance attitude | position will be made favorable.
前記掻込装置１１は左右一対設ける。左右の掻込装置１１の掻込ラグ３５の移動軌跡は、左右中間の中央分草装置７Ｃを基準に、左右略同等に傾斜させる構成とする。
即ち、掻込ラグ３５は後側に至るに従い内側に穀稈を掻き込み、この内側への寄せる角度を、左右略同等にする。
そのため、引起装置８による引起しから掻込装置１１による掻き込みへの受け渡しが円滑にする。
また、前記掻込装置１１の作用側直線部と刈取装置４前後方向とがなす角度が略４５度又は４５度より小さく構成する（図７）。
そのため、掻込装置１１による穀稈搬送方向が刈取装置４の中央に寄せながら穀稈を搬送する。
前記掻込装置１１には、駆動ローラー４０と前側ローラー４１に掻込ラグ３５を有する掻き込みベルト４２を掛け回し、前記前側ローラー４１が前記引起装置８の下部外側従動輪２２と下部内側従動輪２３のうちの、下部外側従動輪２２よりも内側に配置する（図５）。
A pair of left and right scraping devices 11 are provided. The trajectory of the scraping lugs 35 of the left and right scraping devices 11 is configured to be inclined substantially equally to the left and right with reference to the central weeding device 7C between the left and right.
That is, the scraping lug 35 scrapes the cereals inward as it reaches the rear side, and makes the angle toward the inner side substantially equal to the left and right.
Therefore, the transfer from the raising by the pulling device 8 to the scratching by the scratching device 11 becomes smooth.
Further, the angle formed by the working-side linear portion of the scraping device 11 and the reaping device 4 front-rear direction is configured to be approximately 45 degrees or less than 45 degrees (FIG. 7).
For this reason, the culm is conveyed while the culm transporting direction by the scraping device 11 approaches the center of the reaping device 4.
The scraping device 11 is wound around a driving belt 40 and a front roller 41 with a scraping belt 42 having a scraping lug 35, and the front roller 41 has a lower outer driven wheel 22 and a lower inner driven wheel of the pulling device 8. 23, it is arranged inside the lower outer driven wheel 22 (FIG. 5).
そのため、掻込装置１１の掻込ラグ３５の作用域を引起装置８の後側に接近させることができ、引起しから掻き込みへの受け渡しを良好にできて、穀稈の中間部の垂れ下がりを抑制でき、搬送穀稈の乱れや穀稈の詰まりも防止できて、搬送性能を向上させられる。
即ち、掻込ラグ３５は平面視において、「ハ」の字状に穀稈を掻き込むので、掻き込み開始位置から後側に掻込ラグ３５が移動すると、引起装置８からは掻込ラグ３５の移動軌跡が遠くなり、引起装置８の後側に掻込装置１１が作用しないデッドスペースが生じるが、本願では、下部外側従動輪２２よりも内側に前側ローラー４１を配置しているので、掻込ラグ３５の作用域を引起装置８の後側に接近させられ、引起装置８の後側に掻込装置１１が作用しないデッドスペースを小さくし、搬送性能を向上させる。
Therefore, the working area of the scraping lug 35 of the scraping device 11 can be approached to the rear side of the pulling device 8, the transfer from the pulling to the scraping can be performed well, and the middle part of the cereal can be hung down. It is possible to suppress the disturbance of the conveying cereal and the clogging of the cereal, thereby improving the conveying performance.
That is, the scraping lug 35 scrapes the cereal in the shape of “C” in a plan view, and therefore when the scraping lug 35 moves from the scratching start position to the rear side, the pulling lug 35 from the pulling device 8. However, in this application, since the front roller 41 is disposed on the inner side of the lower outer driven wheel 22, the scraper 11 does not act on the rear side of the pulling device 8. The working area of the pull-in lug 35 is brought closer to the rear side of the pulling device 8, the dead space where the scraping device 11 does not act on the rear side of the pulling device 8 is reduced, and the conveyance performance is improved.
また、前側ローラー４１または掻込ラグ３５の回動中心は前記引起装置８の引起ケース２６の外側縁よりも内側となる位置の後方に位置させてもよい。
なお、掻込ラグ３５の回動中心Ｇとは、掻込ラグ３５が非作用域から作用域に反転する箇所を指し、この反転位置を引起装置８の引起ケース２６の外側縁よりも内側となる位置の後方に位置させている。
また、下部外側従動輪２２およびガイド４３と、引起ケース２６の後方に、
前記前側ローラー４１または掻込ラグ３５の回動中心を配置してもよい。
また、換言すると、掻込装置１１の前側ローラー４１は、下部外側従動輪２２および下部内側従動輪２３との間の引起ラグ２４が横直線移動する部分の後方に位置させる（図５）。
そのため、外側の株元から内側に横直線移動する引起ラグ２４により引き寄せられた穀稈を、横直線移動する部分の後方に位置する掻込ラグ３５が掻き込んで、穀稈の垂れ下がりを抑制して搬送姿勢を良好にする。
Further, the rotation center of the front roller 41 or the take-in lug 35 may be positioned behind a position that is inside the outer edge of the pulling case 26 of the pulling device 8.
Note that the rotation center G of the take-up lug 35 refers to a place where the take-up lug 35 is reversed from the non-operation area to the operation area, and this inversion position is located on the inner side of the outer edge of the pulling case 26 of the pulling device 8. It is located behind the position.
In addition, behind the lower outer driven wheel 22 and the guide 43 and the pulling case 26,
The center of rotation of the front roller 41 or the take-up lug 35 may be disposed.
In other words, the front roller 41 of the scavenging device 11 is positioned behind the portion where the pulling lug 24 between the lower outer driven wheel 22 and the lower inner driven wheel 23 moves in a horizontal straight line (FIG. 5).
Therefore, the grain lug 35 located behind the part that moves in a horizontal straight line is raked in the grain straw attracted by the pulling lug 24 that moves in a horizontal straight line from the outside stock to suppress the hanging of the grain straw. To improve the transport posture.
掻込ラグ３５の前端の移動軌跡が、引起装置８の引起ケース２６の下端と略同じ高さとする（図５）。
そのため、掻込ラグ３５の作用域を引起装置８の引起ラグ２４の作用域に接近させられ、特に、倒伏穀稈の搬送姿勢を良好にする。
即ち、掻込ラグ３５は側面視において、後方に至るに従い上側となるように傾斜して後上がりに移動するので、掻き込み開始位置から後側に掻込ラグ３５が移動すると、掻込ラグ３５の移動軌跡が高くなり、穀稈の上側部分を搬送して穀稈の中間部が垂れ下がって搬送姿勢が乱れるが、本願では、掻込ラグ３５の前端の移動軌跡を、引起装置８の引起ケース２６の下端と略同じ高さとしているので、掻込ラグ３５は穀稈の下の部分から作用して、穀稈搬送姿勢を良好にし、搬送性能を向上させる。
また、掻込ラグ３５の前端の移動軌跡が、引起装置８の引起ラグ２４の回動中心よりも下方となるように配置する（例えば、図５）。
The movement trajectory of the front end of the take-up lug 35 is approximately the same height as the lower end of the pulling case 26 of the pulling device 8 (FIG. 5).
For this reason, the working area of the take-up lug 35 can be brought closer to the working area of the pulling lug 24 of the pulling device 8, and in particular, the conveying posture of the fallen cereal can be improved.
That is, in the side view, the scraping lug 35 is inclined so as to be on the upper side as it goes rearward and moves rearwardly upward. Therefore, when the scraping lug 35 moves rearward from the scraping start position, the scraping lug 35 is moved. However, in this application, the movement locus of the front end of the take-up lug 35 is referred to as the raising case of the pulling device 8. Since it is made into the height substantially the same as the lower end of 26, the rake lug 35 acts from the part under the grain candy, makes a corn straw conveyance posture favorable, and improves conveyance performance.
Moreover, it arrange | positions so that the movement locus | trajectory of the front end of the picking lug 35 may become below the rotation center of the raising lug 24 of the raising device 8 (for example, FIG. 5).
そのため、掻込ラグ３５の作用域は、引起装置８の引起ラグ２４の回動中心よりも下方となるので、掻込ラグ３５は穀稈の下の部分から作用して、穀稈搬送姿勢を良好にし、搬送性能を向上させる。
この場合、引起装置８の引起ラグ２４の回動中心とは、引起ラグ２４が直線移動から上方移動に移動方向を変換する箇所を指し、下部外側従動輪２２と下部内側従動輪２３の中心となる。
前記分草装置７のうち、前記刈取装置４の左側部に位置する左分草装置７Ｌの先端Ｔと、右側部に位置する右分草装置７Ｒの先端Ｔが夫々左右に移動自在の構成とする。
左分草装置７Ｌの先端Ｔと、右側部に位置する右分草装置７Ｒの先端Ｔを互いに接近する方向に移動させるとこれらの間に２条分の穀稈を導入し、左分草装置７Ｌの先端Ｔと、右側部に位置する右分草装置７Ｒの先端Ｔを互いに離れる方向に移動させるとこれらの間に４条分の穀稈を導入する構成とする。
Therefore, since the working area of the raking lug 35 is below the rotation center of the pulling lug 24 of the pulling device 8, the raking lug 35 acts from the lower part of the wheat straw to change the grain conveying posture. Improve the conveyance performance.
In this case, the rotation center of the pulling lug 24 of the pulling device 8 refers to a location where the pulling lug 24 changes the moving direction from linear movement to upward movement, and the center of the lower outer driven wheel 22 and the lower inner driven wheel 23. Become.
In the weeding device 7, the tip T of the left weeding device 7L located on the left side of the reaping device 4 and the tip T of the right weeding device 7R located on the right side are respectively movable to the left and right. To do.
When the tip T of the left weeding device 7L and the tip T of the right weeding device 7R located on the right side are moved in a direction approaching each other, two cereal grains are introduced between them, and the left weeding device When the tip L of the 7L and the tip T of the right weeding device 7R located on the right side are moved away from each other, four rows of cereals are introduced between them.
前記分草装置７の先端Ｔの左右移動構成は任意であるが、一例を示すと、前後方向の取付杆５０の先端に分草装置７を固定し、取付杆５０の基部を分草杆３６に縦軸５１により回動自在に取付ける。縦軸５１にはアーム５２の左右中間部を固定し、アーム５２の両端にはワイヤー等の操作伝達部材５３をそれぞれ接続し（図７）、操作伝達部材５３は前記操縦部６に設けた操作レバー５４（図２，図１０）に接続する。
分草装置７は操縦部６に設けた操作レバー５４を操作すると、縦軸５１中心に先端Ｔが左右移動する。
そのため、倒伏穀稈など作業条件によって、分草装置７の先端Ｔを変更するだけでなく、分草装置７の先端Ｔを内外に移動させるだけで、刈幅の変更を行える。
Although the left-right moving configuration of the tip T of the weeding device 7 is arbitrary, for example, the weeding device 7 is fixed to the tip of the mounting rod 50 in the front-rear direction, and the base portion of the mounting rod 50 is attached to the weeding rod 36. Attached to the vertical axis 51 so as to be rotatable. The left and right intermediate portions of the arm 52 are fixed to the vertical axis 51, and the operation transmission member 53 such as a wire is connected to both ends of the arm 52 (FIG. 7). The operation transmission member 53 is an operation provided in the control unit 6. Connect to the lever 54 (FIGS. 2 and 10).
When the weeding device 7 operates the operation lever 54 provided in the control unit 6, the tip T moves to the left and right around the center of the vertical axis 51.
Therefore, the cutting width can be changed not only by changing the tip T of the weeding device 7 but also by moving the tip T of the weeding device 7 in and out depending on the working conditions such as the fallen cereal.
また、左分草装置７Ｌの先端Ｔと右分草装置７Ｒの先端Ｔとの間の間隔は、閉じると刈刃１０の全体刈幅より狭く、開くと刈刃１０の全体刈幅より広くする構成とする（図６，図７）。
そのため、左右の分草装置７を閉じた２条刈のとき、左分草装置７Ｌの先端Ｔと右分草装置７Ｒの先端Ｔとの間の間隔を、刈刃１０の全体刈幅より狭くして刈取作業し、左右の分草装置７を広げた４条刈のとき、左分草装置７Ｌの先端Ｔと右分草装置７Ｒの先端Ｔとの間の間隔を、刈刃１０の全体刈幅より広くして刈取作業する（図７）。
上記の場合、Ｎ条刈りの刈取装置４において、右側の分草装置７の先端Ｔを広げると、右側の分草装置７と隣接する分草装置７の間に二条分の穀稈が入って「Ｎ＋１」条刈が可能となり、左側の分草装置７と隣接する分草装置７の間に二条分の穀稈が入って「Ｎ＋２」条刈が可能となる。
Further, the distance between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is narrower than the entire cutting width of the cutting blade 10 when closed, and wider than the entire cutting width of the cutting blade 10 when opened. It is set as a structure (FIG. 6, FIG. 7).
Therefore, at the time of double cutting with the left and right weeding devices 7 closed, the interval between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is narrower than the entire cutting width of the cutting blade 10. Then, when four-row cutting is performed with the left and right weeding devices 7 spread, the interval between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is set to the entire cutting blade 10. The cutting operation is performed with a width wider than the cutting width (FIG. 7).
In the above case, when the tip T of the right weeding device 7 is expanded in the N-row mowing device 4, two cereal grains are contained between the right weeding device 7 and the adjacent weeding device 7. “N + 1” reaping is possible, and two cereal grains are placed between the left weeding device 7 and the adjacent weeding device 7, and “N + 2” reaping is possible.
例えば、図５，図６の実施例では、２条刈を例えば右側の分草装置７の先端Ｔを広げると、右側の分草装置７と中央の分草装置７の間に二条分の穀稈が入って３条刈とし、左側の分草装置７の先端Ｔを広げると、４条刈に変更する。
図１２の実施例では、３条刈を例えば右側の分草装置７の先端Ｔを広げて４条刈とし、左側の分草装置７の先端Ｔを広げると、５条刈に変更する。
図１３の実施例では、４条刈を例えば右側の分草装置７の先端Ｔを広げて５条刈とし、左側の分草装置７の先端Ｔを広げると、６条刈に変更する。
図１４の実施例では、５条刈を例えば右側の分草装置７の先端Ｔを広げて、隣の分草装置７との間に二条分の穀稈を入れて６条刈とし、左側の分草装置７の先端Ｔを広げると、７条刈に変更する。
図１５の実施例では、６条刈を例えば右側の分草装置７の先端Ｔを広げて７条刈とし、左側の分草装置７の先端Ｔを広げると、８条刈に変更する。
そのため、不規則条間の圃場への適応性を向上させられる。
For example, in the embodiment of FIG. 5 and FIG. 6, when two cuttings are performed, for example, when the tip T of the right weeding device 7 is widened, two cereal grains are placed between the right weeding device 7 and the central weeding device 7. If a cocoon enters and it cuts into 3 lines, and if the front-end | tip T of the weeding device 7 on the left side is expanded, it will change to 4 lines.
In the embodiment of FIG. 12, for example, three-row cutting is changed to four-row cutting by widening the tip T of the right weeding device 7 to make four-row cutting, and widening the tip T of the left-side weeding device 7.
In the embodiment of FIG. 13, for example, the four-row cutting is changed to a six-row cutting when the tip T of the right weeding device 7 is widened to a five-row cutting and the tip T of the left-side weeding device 7 is expanded.
In the embodiment of FIG. 14, for example, widening the tip T of the right weeding device 7, spreading two cereals between the adjacent weeding device 7, and cutting the 5 rows into 6 rows. When the tip T of the weeding device 7 is widened, it is changed to seven-row cutting.
In the embodiment of FIG. 15, 6-row cutting is changed to 8-row cutting when the tip T of the right weeding device 7 is widened to form 7-row cutting, and when the tip T of the left-side weeding device 7 is expanded.
Therefore, the adaptability to the field between irregular stripes can be improved.
図１６の実施例では、７条刈を例えば右側の分草装置７の先端Ｔを広げて８条刈とし、左側の分草装置７の先端Ｔを広げると、９条刈に変更する。
この場合、右側の分草装置７の先端Ｔは、内側位置に位置させた状態で、右側のクローラー３０の最外端部より内側に位置させる。
そのため、旋回時の分草装置７の衝突を防止する。
また、刈取装置４の幅が狭まるので、トラック荷台等への積み込みが容易になる。
この場合、左側の分草装置７の先端Ｔは、内側位置に位置させた状態で、右側のクローラー３０の最外端部より外側に位置させる。
そのため、左側のクローラー３０の轍間距離よりも刈取装置４の刈取幅が広くし、未刈り穀稈の踏みつけを防止する。
なお、図１２〜図１６の実施例では、左右の引起装置８は、下部外側従動輪２２と下部内側従動輪２３とを設けて、引起ラグ２４が横移動する構成とするが、左右中間の引起装置８は、下部に一つの従動輪２２Ａを設け、引起ラグ２４は従動輪２２Ａを中心に上方移動に反転する構成としている。
図１７は、刈取装置４の他の実施例を示し、右側の引起装置８には、下部外側従動輪２２と下部内側従動輪２３とを設けて、引起ラグ２４が横移動する構成とするが、左側の引起装置８は、下部に一つの従動輪２２Ａを設け、引起ラグ２４は従動輪２２Ａを中心に上方移動に反転する構成とし、左側の分草装置７を内側の２条刈りと、外側の３条刈りに変更する構成としている。
そのため、作業条件に合わせて２条刈りと３条刈りに切り替えて能率的に作業できる。
In the embodiment of FIG. 16, seven-row cutting is changed to, for example, eight-row cutting by widening the tip T of the right weeding device 7, and nine-row cutting when the tip T of the left-side weeding device 7 is expanded.
In this case, the tip T of the right weeding device 7 is positioned inside the outermost end of the right crawler 30 in a state where the tip T is positioned at the inner position.
Therefore, the collision of the weeding device 7 at the time of turning is prevented.
Moreover, since the width | variety of the cutting device 4 becomes narrow, loading to a truck bed etc. becomes easy.
In this case, the tip T of the left weeding device 7 is positioned outside the outermost end of the right crawler 30 in a state where the tip T is positioned at the inner position.
Therefore, the cutting width of the cutting device 4 is made wider than the distance between the left crawlers 30 to prevent the uncut wheat straw from being stepped on.
12 to 16, the left and right pulling devices 8 are provided with a lower outer driven wheel 22 and a lower inner driven wheel 23 so that the pulling lug 24 moves laterally. The pulling device 8 is provided with a single driven wheel 22A in the lower portion, and the pulling lug 24 is configured to reverse upwardly about the driven wheel 22A.
FIG. 17 shows another embodiment of the reaping device 4. The right pulling device 8 is provided with a lower outer driven wheel 22 and a lower inner driven wheel 23 so that the pulling lug 24 moves laterally. The left pulling device 8 is provided with one driven wheel 22A in the lower portion, the pulling lug 24 is configured to reverse upwardly moving around the driven wheel 22A, and the left weeding device 7 is cut into two inner strips. It is set as the structure changed to outer 3 line cutting.
Therefore, it is possible to work efficiently by switching to 2-row cutting or 3-row cutting according to the working conditions.
前記掻込装置１１は、カバー（フレーム）６０に駆動ローラー４０と前側ローラー４１を取付ける。カバー６０の後部は刈取装置４の刈取フレーム６１の一部を構成する下部横伝動ケース６２から上方に立ち上げた引起伝動筒６３Ａに支持した支持部材６３に取付ける（図４）。引起伝動筒６３Ａは、引起装置８の駆動輪２１に伝動する伝動軸を備えている。

In addition, since the angle formed by the working side linear portion of the scraping device 11 and the front-rear direction of the reaping device 4 is configured to be approximately 45 degrees or smaller than 45 degrees, the culm transport direction by the rake device 11 is Carry the cereal while moving to the center.
The scraping device 11 is wound around a driving belt 40 and a front roller 41 with a scraping belt 42 having a scraping lug 35, and the front roller 41 is connected to the lower outer driven wheel 22 and the lower inner driven wheel 23 of the pulling device 8. Of these, since the lower outer driven wheel 22 is disposed on the inner side, the working area of the scraping lug 35 of the scraping device 11 can be approached to the rear side of the pulling device 8, so It is possible to improve the delivery performance by improving the delivery performance to the intermediate part of the cereal, preventing the hanging of the middle part of the cereal, preventing the disturbance of the cereal and clogging of the cereal.
即ち、掻込ラグ３５は平面視において、「ハ」の字状に穀稈を掻き込むので、掻き込み開始位置から後側に掻込ラグ３５が移動すると、引起装置８からは掻込ラグ３５の移動軌跡が遠くなり、引起装置８の後側に掻込装置１１が作用しないデッドスペースが生じるが、本願では、下部外側従動輪２２よりも内側に前側ローラー４１を配置しているので、掻込ラグ３５の作用域を引起装置８の後側に接近させられ、引起装置８の後側に掻込装置１１が作用しないデッドスペースを小さくし、搬送性能を向上させる。
また、換言すると、掻込装置１１の前側ローラー４１は、下部外側従動輪２２および下部内側従動輪２３との間の引起ラグ２４が横直線移動する部分の後方に位置させているので、外側の株元から内側に横直線移動する引起ラグ２４により引き寄せられた穀稈を、横直線移動する部分の後方に位置する掻込ラグ３５が掻き込んで、穀稈の垂れ下がりを抑制して搬送姿勢を良好にする。
That is, the scraping lug 35 scrapes the cereal in the shape of “C” in a plan view, and therefore when the scraping lug 35 moves from the scratching start position to the rear side, the pulling lug 35 from the pulling device 8. However, in this application, since the front roller 41 is disposed on the inner side of the lower outer driven wheel 22, the scraper 11 does not act on the rear side of the pulling device 8. The working area of the pull-in lug 35 is brought closer to the rear side of the pulling device 8, the dead space where the scraping device 11 does not act on the rear side of the pulling device 8 is reduced, and the conveyance performance is improved.
In other words, the front roller 41 of the scraping device 11 is positioned behind the portion where the pulling lug 24 between the lower outer driven wheel 22 and the lower inner driven wheel 23 moves in a horizontal straight line. The grain lug 35 that is positioned behind the part that moves in a horizontal straight line is raked in by the pulling lug 24 that moves laterally inward from the stock, and the conveying posture is suppressed by suppressing the hanging of the grain straw. Make good.
掻込ラグ３５の前端の移動軌跡が、引起装置８の引起ケース２６の下端と略同じ高さとしているので、掻込ラグ３５の作用域を引起装置８の引起ラグ２４の作用域に接近させられ、特に、倒伏穀稈の搬送姿勢を良好にする。
即ち、掻込ラグ３５は側面視において、後方に至るに従い上側となるように傾斜して後上がりに移動するので、掻き込み開始位置から後側に掻込ラグ３５が移動すると、掻込ラグ３５の移動軌跡が高くなり、穀稈の上側部分を搬送して穀稈の中間部が垂れ下がって搬送姿勢が乱れるが、本願では、掻込ラグ３５の前端の移動軌跡を、引起装置８の引起ケース２６の下端と略同じ高さとしているので、掻込ラグ３５は穀稈の下の部分から作用して、穀稈搬送姿勢を良好にし、搬送性能を向上させる。
Since the movement locus of the front end of the take-up lug 35 is substantially the same as the lower end of the raising case 26 of the pulling device 8, the working area of the picking lug 35 is brought close to the working area of the pulling lug 24 of the pulling device 8. In particular, it will improve the conveying posture of the overlaid cereal.
That is, in the side view, the scraping lug 35 is inclined so as to be on the upper side as it goes rearward and moves rearwardly upward. Therefore, when the scraping lug 35 moves rearward from the scraping start position, the scraping lug 35 is moved. However, in this application, the movement locus of the front end of the take-up lug 35 is referred to as the raising case of the pulling device 8. Since it is made into the height substantially the same as the lower end of 26, the rake lug 35 acts from the part under the grain candy, makes a corn straw conveyance posture favorable, and improves conveyance performance.
また、掻込ラグ３５の前端の移動軌跡が、引起装置８の引起ラグ２４の回動中心よりも下方となるように配置しているので、掻込ラグ３５の作用域は、引起装置８の引起ラグ２４の回動中心よりも下方となるので、掻込ラグ３５は穀稈の下の部分から作用して、穀稈搬送姿勢を良好にし、搬送性能を向上させる。
分草装置７のうち、刈取装置４の左側部に位置する左分草装置７Ｌの先端Ｔと、右側部に位置する右分草装置７Ｒの先端Ｔが夫々左右に移動自在の構成とし、左分草装置７Ｌの先端Ｔと、右側部に位置する右分草装置７Ｒの先端Ｔを互いに接近する方向に移動させるとこれらの間に２条分の穀稈を導入し、左分草装置７Ｌの先端Ｔと、右側部に位置する右分草装置７Ｒの先端Ｔを互いに離れる方向に移動させるとこれらの間に４条分の穀稈を導入する構成としているので、倒伏穀稈など作業条件によって、分草装置７の先端Ｔを変更するだけでなく、分草装置７の先端Ｔを内外に移動させるだけで、刈幅の変更を行える。
分草装置７は操縦部６に設けた操作レバー５４を操作すると、縦軸５１中心に先端Ｔが左右移動する。
In addition, since the movement trajectory of the front end of the take-up lug 35 is arranged to be below the rotation center of the pull-up lug 24 of the pulling device 8, the working area of the pick-up lug 35 is that of the pulling device 8. Since it becomes below the rotation center of the pulling lug 24, the take-up lug 35 acts from the lower part of the corn straw to improve the corn straw conveying posture and improve the conveying performance.
Among the weeding devices 7, the tip T of the left weeding device 7L located on the left side of the cutting device 4 and the tip T of the right weeding device 7R located on the right side are configured to be movable to the left and right, respectively. When the tip T of the weeding device 7L and the tip T of the right weeding device 7R located on the right side are moved in a direction approaching each other, two cereal grains are introduced between them, and the left weeding device 7L When the tip T of the right side and the tip T of the right weeding device 7R located on the right side are moved away from each other, four rows of cereals are introduced between them. Thus, not only the tip T of the weeding device 7 but also the cutting width can be changed only by moving the tip T of the weeding device 7 in and out.
When the weeding device 7 operates the operation lever 54 provided in the control unit 6, the tip T moves to the left and right around the center of the vertical axis 51.
また、左分草装置７Ｌの先端Ｔと右分草装置７Ｒの先端Ｔとの間の間隔は、閉じると刈刃１０の全体刈幅より狭く、開くと刈刃１０の全体刈幅より広くする構成としているので、左右の分草装置７を閉じた２条刈のとき、左分草装置７Ｌの先端Ｔと右分草装置７Ｒの先端Ｔとの間の間隔を、刈刃１０の全体刈幅より狭くして刈取作業し、左右の分草装置７を広げた４条刈のとき、左分草装置７Ｌの先端Ｔと右分草装置７Ｒの先端Ｔとの間の間隔を、刈刃１０の全体刈幅より広くして刈取作業する。
上記の場合、Ｎ条刈りの刈取装置４において、右側の分草装置７の先端Ｔを広げると、右側の分草装置７と隣接する分草装置７の間に二条分の穀稈が入って「Ｎ＋１」条刈が可能となり、左側の分草装置７と隣接する分草装置７の間に二条分の穀稈が入って「Ｎ＋２」条刈が可能となる。
例えば、図５，６の実施例では、２条刈を例えば右側の分草装置７の先端Ｔを広げると、右側の分草装置７と中央の分草装置７の間に二条分の穀稈が入って３条刈とし、左側の分草装置７の先端Ｔを広げると、４条刈に変更する。
Further, the distance between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is narrower than the entire cutting width of the cutting blade 10 when closed, and wider than the entire cutting width of the cutting blade 10 when opened. Because of the configuration, when performing two-row cutting with the left and right weeding devices 7 closed, the interval between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is set to the overall cutting of the cutting blade 10. When performing 4-row cutting with the width of the weeding device 7 narrower than that of the width, the spacing between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is defined as the cutting blade. The cutting operation is performed with a width wider than the total cutting width of 10.
In the above case, when the tip T of the right weeding device 7 is expanded in the N-row mowing device 4, two cereal grains are contained between the right weeding device 7 and the adjacent weeding device 7. “N + 1” reaping is possible, and two cereal grains are placed between the left weeding device 7 and the adjacent weeding device 7, and “N + 2” reaping is possible.
For example, in the embodiment shown in FIGS. 5 and 6, when two cuttings are performed, for example, when the tip T of the right weeding device 7 is widened, two cereal grains are placed between the right weeding device 7 and the central weeding device 7. Enters 3 cuts, and when the tip T of the left weeding device 7 is widened, it is changed to 4 cuts.
図１２の実施例では、３条刈を例えば右側の分草装置７の先端Ｔを広げて４条刈とし、左側の分草装置７の先端Ｔを広げると、５条刈に変更する。
図１３の実施例では、４条刈を例えば右側の分草装置７の先端Ｔを広げて５条刈とし、左側の分草装置７の先端Ｔを広げると、６条刈に変更する。
図１４の実施例では、５条刈を例えば右側の分草装置７の先端Ｔを広げて、隣の分草装置７との間に二条分の穀稈を入れて６条刈とし、左側の分草装置７の先端Ｔを広げると、７条刈に変更する。
図１５の実施例では、６条刈を例えば右側の分草装置７の先端Ｔを広げて７条刈とし、左側の分草装置７の先端Ｔを広げると、８条刈に変更する。
図１６の実施例では、７条刈を例えば右側の分草装置７の先端Ｔを広げて８条刈とし、左側の分草装置７の先端Ｔを広げると、９条刈に変更する。
この場合、右側の分草装置７の先端Ｔは、内側位置に位置させた状態で、右側のクローラー３０の最外端部より内側に位置させる。
そのため、旋回時の分草装置７の衝突を防止する。
In the embodiment of FIG. 12, for example, three-row cutting is changed to four-row cutting by widening the tip T of the right weeding device 7 to make four-row cutting, and widening the tip T of the left-side weeding device 7.
In the embodiment of FIG. 13, for example, the four-row cutting is changed to a six-row cutting when the tip T of the right weeding device 7 is widened to a five-row cutting and the tip T of the left-side weeding device 7 is expanded.
In the embodiment of FIG. 14, for example, widening the tip T of the right weeding device 7, spreading two cereals between the adjacent weeding device 7, and cutting the 5 rows into 6 rows. When the tip T of the weeding device 7 is widened, it is changed to seven-row cutting.
In the embodiment of FIG. 15, 6-row cutting is changed to 8-row cutting when the tip T of the right weeding device 7 is widened to form 7-row cutting, and when the tip T of the left-side weeding device 7 is expanded.
In the embodiment of FIG. 16, seven-row cutting is changed to, for example, eight-row cutting by widening the tip T of the right weeding device 7, and nine-row cutting when the tip T of the left-side weeding device 7 is expanded.
In this case, the tip T of the right weeding device 7 is positioned inside the outermost end of the right crawler 30 in a state where the tip T is positioned at the inner position.
Therefore, the collision of the weeding device 7 at the time of turning is prevented.
また、刈取装置４の幅が狭まるので、トラック荷台等への積み込みが容易になる。
この場合、左側の分草装置７の先端Ｔは、内側位置に位置させた状態で、右側のクローラー３０の最外端部より外側に位置させているので、左側のクローラー３０の轍間距離よりも刈取装置４の刈取幅が広くし、未刈り穀稈の踏みつけを防止する。
図１７は、刈取装置４の他の実施例では、右側の引起装置８には、下部外側従動輪２２と下部内側従動輪２３とを設けて、引起ラグ２４が横移動する構成とするが、左側の引起装置８は、下部に一つの従動輪２２Ａを設け、引起ラグ２４は従動輪２２Ａを中心に上方移動に反転する構成とし、左側の分草装置７を内側の２条刈りと、外側の３条刈りにに変更する構成としている。
そのため、作業条件に合わせて２条刈りと３条刈りに切り替えて能率的に作業できる。
Moreover, since the width | variety of the cutting device 4 becomes narrow, loading to a truck bed etc. becomes easy.
In this case, the tip T of the left weeding device 7 is positioned outside the outermost end of the right crawler 30 in a state where the tip T is positioned at the inner position. Also, the cutting width of the mowing device 4 is widened, and the uncut rice cake is prevented from being stepped on.
FIG. 17 shows another embodiment of the mowing device 4 in which the right pulling device 8 is provided with a lower outer driven wheel 22 and a lower inner driven wheel 23 so that the pulling lug 24 moves laterally. The pulling device 8 on the left side is provided with one driven wheel 22A at the bottom, and the pulling lug 24 is configured to reversely move upward around the driven wheel 22A. It is set as the structure changed to 3 cuttings.
Therefore, it is possible to work efficiently by switching to 2-row cutting or 3-row cutting according to the working conditions.
掻込装置１１は、カバー６０に従動輪前側ローラー４１と駆動輪駆動ローラー４０を取付け、カバー６０の前部は取付部材取付部材６５を介して支持部材支持部材６６の先端側に取付け、支持部材６６の基部は分草杆３６に固定しているので、支持部材６６および取付部材６５がカバー６０の分草杆３６側となって、掻込ラグ３５の作用域を外れて配置でき、穀稈との干渉を抑制させられる。
即ち、掻込装置１１のカバー６０の前部を前記刈取装置４の刈取フレーム６１側に取付ける取付部材６５を、掻込ラグ３５が穀稈を搬送する搬送作用域を外して配置することになって、掻込装置１１により掻き込み搬送される穀稈は取付部材６５に干渉されずに搬送され、搬送姿勢を良好にする。
この場合、前記取付部材６５は平面あるいは正面視において、カバー６０上に配置しているので、取付部材６５に藁屑等が引っ掛かるのを防止し、カバー６０上の藁屑の堆積を防止し、その結果、掻込装置１１による穀稈の搬送姿勢を良好にする。
The scraping device 11 attaches the follower wheel front roller 41 and the drive wheel drive roller 40 to the cover 60, and the front part of the cover 60 is attached to the front end side of the support member support member 66 via the attachment member attachment member 65. Since the base portion of 66 is fixed to the weed pod 36, the support member 66 and the attachment member 65 can be arranged on the side of the weed ridge 36 of the cover 60 and can be disposed outside the working area of the take-up lug 35. Interference can be suppressed.
That is, the attachment member 65 that attaches the front portion of the cover 60 of the scraping device 11 to the cutting frame 61 side of the harvesting device 4 is disposed with the transporting area where the scraping lug 35 transports the cereals removed. Thus, the culm that is scraped and transported by the scraping device 11 is transported without being interfered with the attachment member 65, and the transport posture is improved.
In this case, since the mounting member 65 is disposed on the cover 60 in a plan view or a front view, the mounting member 65 is prevented from being caught by the sawdust and the like, and the accumulation of the sawdust on the cover 60 is prevented. As a result, the posture of carrying the cereal with the scraping device 11 is improved.
図１８，１９の掻込装置１１の支持構成の他の実施例では、取付部材６５は掻込装置１１の掻込ラグ３５の穀稈搬送非作用側に設置しているので、取付部材６５の存在が掻込装置１１の掻込ラグ３５の作用域に影響するのを防止し、掻込装置１１による穀稈の搬送姿勢を良好にする。
図２０，２１の掻込装置１１の支持構成の他の実施例では、前記取付部材６５は、支持部材６６（取付部３７）に固定の固定側取付部材６８と該固定側取付部材６８に対して移動自在の移動側取付部材６９とにより構成し、前記移動側取付部材６９に掻込装置１１の前記カバー６０を取付けているので、移動側取付部材６９の固定側取付部材６８に対する取付位置を変更することで、掻込装置１１の前側ローラー４１の位置を調節する。
即ち、カバー６０は駆動ローラー４０の軸心を中心に前側ローラー４１が前後方向に回動するように構成し、例えば、刈取条数の変更に対応させて、掻込装置１１の前側ローラー４１の位置を変更調節する。
18 and 19, the mounting member 65 is installed on the non-working side of the scraping lug 35 of the scraping device 11. The presence prevents the working area of the raking lug 35 of the scraping device 11 from being affected, and improves the posture of conveying the cereal by the scraping device 11.
20 and 21, the attachment member 65 is fixed to the support member 66 (attachment portion 37) with respect to the fixed-side attachment member 68 and the fixed-side attachment member 68. The movable side mounting member 69 is configured to be movable, and the cover 60 of the scraping device 11 is mounted on the movable side mounting member 69. Therefore, the mounting position of the movable side mounting member 69 with respect to the fixed side mounting member 68 is determined. By changing, the position of the front roller 41 of the scraping device 11 is adjusted.
That is, the cover 60 is configured such that the front roller 41 rotates in the front-rear direction around the axis of the drive roller 40. For example, the cover 60 corresponds to a change in the number of cutting lines, and the front roller 41 of the scraping device 11 Change and adjust the position.
例えば、条数が多いときは、引き起こされた穀稈姿勢が寝た姿勢になりやすいので、前側ローラー４１の位置を引起装置８に接近させ、反対に、条数が少ないときは、引き起こされた穀稈姿勢が直立するので、前側ローラー４１の位置を引起装置８から離して刈取作業を行う。
そのため、作物条件、作業者の作業条件等によって、掻込装置１１の位置を選択変更させられるので、掻き込み搬送姿勢を良好にする。
掻込装置１１の前側ローラー４１は下部外側従動輪２２および下部内側従動輪２３との間の引起ラグ２４が横直線移動する部分の後方に位置させ、掻込装置１１の掻込ラグ３５は後方に至るに従い内側を通るように構成しているので、掻込装置１１の掻込ラグ３５の作用域を、引起装置８の後側に接近させられて、搬送姿勢を良好にする。
掻込装置１１の前側ローラー４１は、引起装置８の引起ラグ２４の引起し開始の作用点よりも、内側に配置構成しているので、掻込装置１１の掻込ラグ３５は引起装置８の引起ラグ２４が引起した穀稈を直ぐに掻き込み、搬送姿勢を良好にする。
For example, when the number of ridges is large, the induced cereal posture tends to be a sleeping posture, so the position of the front roller 41 is brought closer to the pulling device 8, and conversely, when the number of ridges is small, it is caused Since the cereal posture is upright, the cutting operation is performed with the position of the front roller 41 away from the pulling device 8.
Therefore, the position of the scraping device 11 can be selected and changed depending on the crop conditions, the worker's working conditions, and the like, so that the scraping transport posture is improved.
The front roller 41 of the scraping device 11 is positioned behind the portion where the pulling lug 24 between the lower outer driven wheel 22 and the lower inner driven wheel 23 moves in a horizontal straight line, and the scraping lug 35 of the scraping device 11 is rearward. Therefore, the working area of the scraping lug 35 of the scraping device 11 is brought closer to the rear side of the pulling device 8 to improve the conveying posture.
Since the front roller 41 of the scraping device 11 is arranged on the inner side of the action starting point of the pulling lug 24 of the pulling device 8, the scraping lug 35 of the scraping device 11 is the same as that of the pulling device 8. Immediately scrape the cereals raised by the pulling lug 24 to improve the conveying posture.
即ち、掻込ラグ３５は平面視において、「ハ」の字状に穀稈を掻き込むので、掻き込み開始位置から斜め後方に掻込ラグ３５が移動し、左右方向に直線移動する引起装置８の掻込ラグ３５の移動軌跡から遠くなるので、掻込装置１１の前側ローラー４１は、引起装置８の引起ラグ２４の引起し開始の作用点よりも、内側に配置構成することにより、掻込装置１１の掻込ラグ３５の掻き込み作用域を引起装置８の引起ラグ２４の引起し作用域に接近させられ、搬送姿勢を良好にする。
掻込装置１１の掻込ラグ３５の回動中心を、引起装置８の引起ラグ２４の引起し開始の作用点よりも、内側に配置構成しているので、掻込装置１１の掻込ラグ３５は引起装置８の引起ラグ２４が引起した穀稈を直ぐに掻き込み、搬送姿勢を良好にする。
掻込装置１１の掻込ラグ３５の穀稈搬送作用側を、引起装置８の引起ラグ２４の引起し開始の作用点よりも、内側に配置構成しているので、掻込装置１１の掻込ラグ３５の掻き込み作用域を引起装置８の引起ラグ２４の引起し作用域に接近させられ、搬送姿勢を良好にする。
In other words, since the scraping lug 35 scrapes the cereal rice cake in a “C” shape in plan view, the scraping lug 35 moves diagonally backward from the scraping start position, and the pulling device 8 moves linearly in the left-right direction. Therefore, the front roller 41 of the scraping device 11 is disposed on the inner side of the action starting point of the pulling lug 24 of the pulling device 8 so as to be scratched. The scraping action area of the scraping lug 35 of the apparatus 11 is brought close to the pulling action area of the pulling lug 24 of the pulling apparatus 8 to improve the conveying posture.
Since the rotation center of the take-up lug 35 of the take-up device 11 is arranged on the inner side of the action starting point of the raising lug 24 of the pull-up device 8, the take-up lug 35 of the take-up device 11 is arranged.
