特開２００６−１４７０８号公報（段落〔００２２〕、図１，２）JP 2006-14708 (paragraph [0022], FIGS. 1 and 2)

上記の全稈投入型コンバインにおいては、刈取前処理部の刈り幅の左右両側に分草体が設けられているのであるが、穀稈が大きく倒伏している場合、刈り幅端部近くの倒伏した穀稈が分草体によって引き起こされずに、分草体の下側に潜り込んだ状態となることがある。
このように倒伏穀稈が分草体の下側に潜り込んでしまうと、対地的に低く位置する分草体の下縁によって穀稈が踏み潰された状態となり、より一層倒伏させられて、穂先側を掻き上げる掻込みリールによる引き起こし作用も付与できない状態となることがある。 In the above all-fired combine combine, weeds are provided on both the left and right sides of the cutting width of the pre-cutting processing section. The cereal bud may not be caused by the herbaceous body but may be in a state of being submerged in the lower part of the herbaceous body.
In this way, if the lodging cedar has entered the lower side of the weed body, the cedar has been crushed by the lower edge of the weed body that is located lower on the ground, and it is further lowered, and the tip side is There may be a case where the causing action by the scraping reel is not provided.

本発明の目的は、分草体による倒伏穀稈の踏み潰しを避けて、掻込みリールなどの他装置による引き起こし作用が及び易くすることにより、倒伏穀稈の刈取を行い易くした全稈投入型コンバインを提供することにある。   The object of the present invention is to avoid the crushing of the fallen cereal by the weed body and to make it easier to cause the fallen cereal to be reaped by making it easier to cause the action by other devices such as a take-up reel. Is to provide.

上記目的を達成するために講じた本発明の技術手段は、次の点に構成上の特徴、及び作用効果がある。
〔解決手段１〕
本発明は、請求項１の記載のように、刈取前処理部で刈取られた穀稈の全体を脱穀装置の扱室に投入して脱穀処理する全稈投入型コンバインにおいて、
前記刈取前処理部には刈取作用範囲の左右両側で植立穀稈を分草する分草体を設けてあり、
この分草体の下縁を、側面視で先端部を含む前方側に位置する下縁部分が、後方側に位置する下縁部分よりも高くなるように形成して、刈取作業姿勢における前記前方側の下縁部分と地面との間に、前記後方側の下縁部分と地面との隙間よりも大きな隙間が形成されるようにしたことを特徴とする。 The technical means of the present invention taken in order to achieve the above object has the following structural features and operational effects.
[Solution 1]
The present invention, as described in claim 1, in an all-throw-in type combine that performs threshing processing by putting the whole cereal harvested in the pre-cutting processing unit into the handling room of the threshing device,
The cutting pretreatment unit is provided with a weeding body for weeding the planted cereals on the left and right sides of the cutting action range,
The lower edge of this weed body is formed such that the lower edge portion located on the front side including the tip portion in a side view is higher than the lower edge portion located on the rear side, and the front side in the cutting work posture A gap larger than the gap between the lower edge portion on the rear side and the ground is formed between the lower edge portion and the ground.

〔作用効果〕
上記構成によると、分草体の下縁部分のうち、先端部を含む前方側に位置する下縁部分が、後方側に位置する下縁部分よりも高くなり、その前方側の下縁部分と地面との間に、後方側の下縁部分と地面との隙間よりも大きな隙間が形成される。したがって、この隙間が存在する箇所では、倒伏して分草体の下側に潜り込んだ状態の穀稈が強く押し潰された状態となることを避けられるので、上方の掻き上げ用の掻込みリールなどの他装置による引き起こし作用を付与し易くなる利点がある。 [Function and effect]
According to the said structure, the lower edge part located in the front side including the front-end | tip part among the lower edge parts of a weed body becomes higher than the lower edge part located in back side, The lower edge part of the front side, and the ground A gap larger than the gap between the lower edge portion on the rear side and the ground is formed. Therefore, in the location where this gap exists, it is possible to avoid the state that the cereals that have fallen down and have entered the lower part of the herbaceous body are strongly crushed, so that the upper scraping reel etc. There exists an advantage which becomes easy to give the cause effect by other apparatuses.

〔解決手段２〕
本発明の全稈投入型コンバインでは、請求項２の記載のように、分草体の下縁を、側面視で刈刃よりも前方側に位置して先端部を含む下縁部分が、刈刃の下方に位置する下縁部分よりも高くなるように形成して、刈取作業姿勢における刈刃の前方側の下縁部分と地面との間に、刈刃の下方に位置する下縁部分と地面との隙間よりも大きな隙間が形成されるようにしてもよい。 [Solution 2]
In the all-throw-in type combine of the present invention, as described in claim 2, the lower edge portion of the weeding body located on the front side of the cutting blade in a side view and including the tip portion is a cutting blade. The lower edge portion and the ground located below the cutting blade are formed between the lower edge portion and the ground on the front side of the cutting blade in the cutting work posture. A gap larger than the gap may be formed.

〔作用効果〕
上記構成によると、地面との隙間が大きい分草体の下縁部分を、側面視で刈刃よりも前方側に位置して先端部を含む下縁部分としたものであるから、倒伏茎稈の踏み潰しがない状態を刈刃の近くまで続けて、刈刃による倒伏穀稈の切断を良好に行わせ易い利点がある。 [Function and effect]
According to the above configuration, since the lower edge portion of the herb body having a large gap with the ground is the lower edge portion including the tip portion located on the front side of the cutting blade in a side view, There is an advantage that the state where there is no crushing is continued to the vicinity of the cutting blade, and the fallen cereal is easily cut with the cutting blade.

〔解決手段３〕
本発明の全稈投入型コンバインでは、請求項３の記載のように、刈刃の直前位置の分草体の下縁部分が刈刃先端と同程度の高さ位置に設定されていてもよい。 [Solution 3]
In the full throw-in type combine of the present invention, as described in claim 3, the lower edge portion of the weed body immediately before the cutting blade may be set at a height position similar to the tip of the cutting blade.

〔作用効果〕
上記のように、刈刃の直前位置の分草体の下縁部分が刈刃先端と同程度の高さ位置に設定されていると、刈刃先端位置よりも下方側への分草体による倒伏穀稈への踏み潰しが、より確実に生じ難いので、刈刃による倒伏穀稈の切断がより良好に行われ易い利点がある。 [Function and effect]
As described above, when the lower edge portion of the weed body just before the cutting blade is set at a height position similar to the tip of the cutting blade, the fallen grain by the weed body below the cutting blade tip position Since the crushing to the cocoon is less likely to occur more reliably, there is an advantage that the fallen cereal is easily cut with the cutting blade.

〔解決手段４〕
本発明の全稈投入型コンバインでは、請求項４の記載のように、刈刃よりも前方側における分草体の下縁部分のうち、前記刈刃から前方側へ離れた先端側箇所の下縁部分には、刈刃に近い側の下縁部分に対して先端側ほど高くなる傾斜下縁を形成してもよい。 [Solution 4]
In the all-throw-in type combine according to the present invention, as described in claim 4, the lower edge of the tip side portion that is farther forward from the cutting blade, of the lower edge portion of the weeding body in front of the cutting blade. The portion may be formed with an inclined lower edge that becomes higher toward the tip side with respect to the lower edge portion near the cutting blade.

〔作用効果〕
上記のように、刈刃から前方側へ離れた先端側箇所の下縁部分を、刈刃に近い後端側箇所の下縁部分に対して先端側ほど高くなる傾斜下縁に形成すると、分草体の先端位置の対地高さは、地面からかなり離れた高い位置となる。このため、大きく倒伏した状態の穀稈は分草体による引き起こし作用を受けることができず、逆に傾斜下縁に沿って分草体の下縁側に案内されることになる。
従来では、分草体による引き起こし機能を極力有効に発揮させることを目的として分草体先端の位置をできるだけ地面に近づけるようにすることが技術常識とされていたものであるが、本発明では、発想を転換して、上記のような作用が生じる構成を採用した。
すなわち、分草体先端位置を高くして、分草体の引き起こし機能は、その引き起こし作用がスムースに行われ易いところの、極端な倒伏状態ではない穀稈に対してだけ作用するようにし、大きく倒伏した穀稈に対しては、無理に分草作用を働かせると、絡みついた穀稈が千切れたり、脱粒が生じる虞があるので、引き起こし作用が働かない下縁側へ案内して、かつ踏み潰しの生じ難い状態で切断することができるようにしたものである。
したがって、分草体による穀稈の分草や引き起こし作用を、穀稈の引き千切りや踏み潰しを生じ難い状態で行いながら刈取作業を良好に行ない易い利点がある。 [Function and effect]
As described above, when the lower edge portion of the tip side portion away from the cutting blade to the front side is formed as an inclined lower edge that becomes higher toward the tip side than the lower edge portion of the rear end side portion close to the cutting blade, The ground height of the tip position of the grass body is a high position that is considerably away from the ground. For this reason, the grain cocoon in the state of being greatly overlaid cannot receive the action caused by the herbaceous body and is guided to the lower edge side of the herbaceous body along the inclined lower edge.
Conventionally, it has been common technical knowledge to make the position of the tip of the herbaceous body as close to the ground as possible for the purpose of causing the function caused by the herbic body to be as effective as possible. The structure which converted and produced the above effects | actions was employ | adopted.
In other words, by raising the tip position of the herbaceous body, the herbaceous body's triggering function has been greatly reduced by acting only on cereals that are not in an extreme lying state, although the triggering action is easily performed. For cereals, if the weeding action is applied forcibly, the entangled cereals may be broken or shattered, leading to the lower edge where the action does not work and the occurrence of trampling It can be cut in a difficult state.
Therefore, there is an advantage that the cutting work can be favorably performed while performing the weeding and raising action of the cereal by the weed body in a state in which it is difficult to cause the chopping and shredding of the cereal.

〔全稈投入型コンバインの全体構成〕
以下、本発明の実施の形態の一例を図面の記載に基づいて説明する。
図１および図３に、本発明に係る全稈投入型のコンバインの全体側面が、また、図２に、その全体平面がそれぞれ示されている。
このコンバインは、左右一対のクローラ走行装置１を備えた機体２に、運転部４、軸流型の脱穀装置５、および、穀粒容器６が搭載されるとともに、前記脱穀装置５の前部に後部側の横軸芯周りで上下揺動自在に刈取り作物搬送用のフィーダ７が連結され、このフィーダ７の前端に機体横幅に相当する刈幅を有する刈取前処理部３が連結された構造となっている。前記運転部４における座席下方に、エンジン（図外）を収容した原動部が設けられている。 [Overall configuration of all-throw-in type combine combiner]
Hereinafter, an example of an embodiment of the present invention will be described based on the drawings.
1 and 3 show the entire side surface of the all-fired combine according to the present invention, and FIG. 2 shows the entire plane.

A structure in which a feeder 7 for transporting a harvested crop is connected to be swingable up and down around a horizontal axis on the rear side, and a pre-cutting processing unit 3 having a cutting width corresponding to the width of the machine body is connected to the front end of the feeder 7. It has become. A driving unit that houses an engine (not shown) is provided below the seat in the driving unit 4.

〔刈取前処理部の構成〕
前記刈取前処理部３は、左右一対の分草フレーム３０に亘ってバリカン型の刈取装置３１、刈り取った作物を横送りして前記フィーダ７の始端部に送り込むオーガ３２が架設された構造となっており、分草フレーム３０の前端側には分草体３３が装着されている。
前記フィーダ７と機体２との間に架設された油圧シリンダ１４の伸縮作動によって刈取前処理部３がフィーダ７と一体に昇降されるようになっている。また、刈取前処理部３の前部上方に、植立した作物を後方に掻き込む掻込みリール３５が装備されている。 [Configuration of pre-cutting processing unit]
The pre-cutting processing unit 3 has a structure in which a clipper-type cutting device 31 and a auger 32 that feeds the harvested crop to the start end of the feeder 7 are installed over a pair of right and left weed frames 30. A weeding body 33 is mounted on the front end side of the weeding frame 30.
The pre-cutting processing unit 3 is moved up and down integrally with the feeder 7 by an expansion / contraction operation of a hydraulic cylinder 14 installed between the feeder 7 and the machine body 2. Further, a scraping reel 35 for scraping the planted crops backward is provided above the front part of the pre-cutting processing unit 3.

前記掻込みリール３５は、支点ｂ周りに上下揺動自在な左右一対の支持アーム１６の前部に支持ブラケット１７を介して支架されており、油圧シリンダ１５によって支持アーム１６を上下揺動することで掻込みリール３５の掻込み作用高さを変更することができるとともに、支持ブラケット１７を支持アーム１６に沿ってスライド調節することで掻込み作用位置を前後に調節することが可能となっている。   The take-up reel 35 is supported via a support bracket 17 on the front part of a pair of left and right support arms 16 that can swing up and down around a fulcrum b, and the support arm 16 is swung up and down by a hydraulic cylinder 15. It is possible to change the height of the scraping action of the scraping reel 35 and to adjust the position of the scratching action back and forth by adjusting the slide of the support bracket 17 along the support arm 16. .

掻込みリール３５自体は側面形状が五角形に構成され、その角部に回転可能に横架した丸パイプ製のタイン取付け杆３６に多数本のタイン３７が並列装着されている。このタイン３７の駆動形態は周知のものであるため、詳細な構造の説明は省略するが、前記タイン取付け杆３６は、掻込みリール３５の前方への公転に対応して逆方向に同速度で相対自転されることで、掻込みリール３５の回転にかかわらず常に一定姿勢にあるように構成されており、これによって各タイン取付け杆３６に取付けられたタイン３７が常に下向きの掻き込み姿勢に維持されるようになっている。   The take-up reel 35 itself has a pentagonal side shape, and a plurality of tines 37 are mounted in parallel on a tine mounting rod 36 made of a round pipe that is rotatably mounted on the corner of the take-up reel 35. Since the drive form of the tine 37 is well known, detailed description of the structure will be omitted, but the tine mounting rod 36 has the same speed in the reverse direction in response to the forward revolution of the take-up reel 35. By being rotated relative to each other, it is configured so as to be always in a fixed posture regardless of the rotation of the take-up reel 35, and thereby the tine 37 attached to each tine attachment rod 36 is always kept in a downward-take-down posture. It has come to be.

刈取前処理部３に設けられた前記刈取装置３１の刈刃３１ａ、及び前記オーガ３２は、夫々が右側の分草フレーム３０の横外側に配備された駆動機構（図外）を介して駆動されるように構成されている。また、前記掻込みリール３５に対する駆動系は、前記前記刈取装置３１及びオーガ３２への駆動系の途中から分岐された動力が伝動チェーン１９及び伝動ベルト１８を介して伝達されるように構成されている。   The cutting blade 31a of the cutting device 31 and the auger 32 provided in the pre-cutting processing unit 3 are driven via a drive mechanism (not shown) provided on the lateral outside of the right weeding frame 30. It is comprised so that. The drive system for the take-up reel 35 is configured such that the power branched from the middle of the drive system to the reaping device 31 and the auger 32 is transmitted via the transmission chain 19 and the transmission belt 18. Yes.

〔分草体の構成〕
前記分草フレーム３０の前端側に装着された分草体３３は次のように構成されている。
図３乃至図５に示すように、後端側を分草フレーム３０に連結された分草体３３は、その下縁を、側面視で先端部３４を含む前方側に位置する下縁部分３３ａが、後方側に位置する下縁部分３３ｂよりも高くなるように形成して、刈取作業姿勢における前記前方側の下縁部分３３ａと地面との間に、前記後方側の下縁部分３３ｂと地面との隙間よりも大きな隙間ｓが形成されるようにしてある。 [Composition of herbaceous body]
The weeding body 33 mounted on the front end side of the weeding frame 30 is configured as follows.
As shown in FIG. 3 to FIG. 5, the weeding body 33 whose rear end side is connected to the weeding frame 30 has a lower edge portion having a lower edge portion 33 a located on the front side including the distal end portion 34 in a side view. The lower edge portion 33b positioned on the rear side is formed to be higher than the lower edge portion 33a on the front side in the cutting operation posture and the ground. A gap s larger than this gap is formed.

すなわち、刈刃３１ａの下方に位置する後方側の下縁部分３３ｂは、刈取作業姿勢ではほとんど地面と摺接する程度にまで低く設定されている。この後方側の下縁部分３３ｂに対して、側面視で刈刃３１ａよりも前方側に位置して分草体３３の先端部を含む範囲に設けられた前方側の下縁部分３３ａは、刈取作業姿勢における刈刃３１ａの先端の対地高さと同程度になるように高い位置に設けられていて、両下縁部分３３ａ，３３ｂ同士の間には段差が形成されている。
したがって、この段差に相当する隙間ｓが前記前方側の下縁部分３３ａと地面との間に、刈刃３１ａの下方に位置する下縁部分３３ｂと地面との隙間よりも大きな隙間ｓとして形成されることになる。 That is, the lower edge portion 33b on the rear side located below the cutting blade 31a is set so low that it almost slides on the ground in the cutting work posture. With respect to the lower edge portion 33b on the rear side, the lower edge portion 33a on the front side provided in a range including the front end portion of the weeding body 33 is located in front of the cutting blade 31a in a side view. It is provided at a high position so as to be approximately the same as the ground height at the tip of the cutting blade 31a in the posture, and a step is formed between the lower edge portions 33a and 33b.
Therefore, a gap s corresponding to this step is formed as a gap s between the lower edge portion 33a of the front side and the ground, which is larger than the gap between the lower edge portion 33b located below the cutting blade 31a and the ground. Will be.

刈刃３１ａよりも前方側における分草体３３の下縁部分３３ａのうち、前記刈刃３１ａから前方側へ離れた先端側箇所の下縁部分３３ａには、刈刃３１ａの下方に位置する後方側の下縁部分３３ｂや、前方側の下縁部分３３ａのうちでも刈刃３１ａに近い側の下縁部分３３ａに対しては、傾斜して交差する下縁となるように、先端側ほど高くなる傾斜下縁３３ｃが形成されている。   Of the lower edge portion 33a of the weeding body 33 on the front side of the cutting blade 31a, the lower edge portion 33a of the tip side portion away from the cutting blade 31a to the front side has a rear side located below the cutting blade 31a. Of the lower edge portion 33b and the lower edge portion 33a on the front side, the lower edge portion 33a on the side close to the cutting blade 31a becomes higher toward the tip side so as to be an inclined lower edge. An inclined lower edge 33c is formed.

上述のように構成した分草体３３による作用状態を図４に示す。
図４の図中、仮想線で示すように、分草体３３の近くで倒伏している穀稈ａ’が存在している場合、前述の前方側の下縁部分３３ａによる隙間ｓが存在していなければ、倒伏穀稈の株元近くが踏み潰されて極端な倒伏状態となることがある。
これに比べて、本発明のように、前記前方側の下縁部分３３ａによる隙間ｓが存在していることにより、同図中に実線で示すように、倒伏姿勢の穀稈の株元を踏み潰すことなく、分草体３３の下側に潜り込んだ穀稈ａを、ある程度の起き上がり状態のままで刈刃３１ａによる切断をすることが可能となる。 FIG. 4 shows an action state of the herb body 33 configured as described above.
In the drawing of FIG. 4, as indicated by the phantom line, when there is a grain culm a ′ lying down near the herbaceous body 33, there is a gap s due to the aforementioned lower edge portion 33 a on the front side. If not, the stock of the fallen cereals may be crushed and become an extreme lodging state.
Compared to this, the presence of the gap s by the lower edge portion 33a of the front side as in the present invention makes it possible to step on the cedar stock of the lying posture as shown by the solid line in the figure. Without crushing, it becomes possible to cut the cereals a that have entered under the weed body 33 with the cutting blade 31a while being raised to some extent.

尚、図３に示すように、この実施形態における分草体３３の下縁は、刈刃３１ａの直前で刈り刃の下方に回り込むように屈曲された形状であり、実際に刈刃３１ａの先端が存在する箇所の分草体３３の前後方向位置では、分草体３３の下縁は刈刃３１ａよりも低い後方側の下縁部分３３ｂである。
したがって、刈刃３１ａによる倒伏穀稈の切断時点では、分草体３３の下縁が倒伏した穀稈の株元を踏んだ状態となっていることがある。しかしながら、穀稈ａは踏まれる直前まで掻き込みリール３５による引き起こし作用を受けて図４に示すようにある程度起きあがった状態となっており、踏まれてから機体進行中の僅かな時間差で切断されるものであり、踏まれた途端に完全な倒伏状態になるものでもないので、支障なく切断することが可能となる。 In addition, as shown in FIG. 3, the lower edge of the weeding body 33 in this embodiment is a shape bent so as to wrap around the lower portion of the cutting blade immediately before the cutting blade 31a, and the tip of the cutting blade 31a is actually formed. At the position in the front-rear direction of the weed body 33 where it exists, the lower edge of the weed body 33 is a lower edge portion 33b on the rear side lower than the cutting blade 31a.
Therefore, at the time of cutting the fallen cereal by the cutting blade 31a, the lower edge of the weed body 33 may be in a state of stepping on the stock of the fallen cereal. However, the cereal a is in a state of being raised to some extent as shown in FIG. 4 due to the action caused by the scraping reel 35 until just before being stepped on, and is cut off with a slight time difference during the aircraft progressing after being stepped on. Since it is not intended to be in a completely lying state as soon as it is stepped on, it can be cut without any trouble.

また、分草体３３の下縁のうち、先端側に傾斜下縁３３ｃを形成した場合には、図５に示すように、分草体３３の先端の対地高さが、刈刃３１ａと比べてもかなり高い位置となる。
したがって、この分草体３３で分草を行った場合、分草体３３による引き起こし機能が働くのは、分草体３３の先端よりも高い位置で分草体３３と接触した穀稈であり、あまり大きく倒伏した状態ではない穀稈に対してのみ、分草、及び引き起こし作用が働くことになる。
このように、あまり大きく倒伏していない穀稈であれば、その穀稈相互の絡みつき度合いも比較的少ないので、絡みついた穀稈が千切れたり、脱粒が生じる虞の少ないスムースな分草ならびに引き起こしを行い易いものである。 Further, when the inclined lower edge 33c is formed on the tip side of the lower edge of the weed body 33, as shown in FIG. 5, the ground height of the tip of the weed body 33 is higher than that of the cutting blade 31a. It will be quite high.
Therefore, when weeding with this weed body 33, it is the cereal buds that contact the weed body 33 at a position higher than the tip of the weed body 33, and the function caused by the weed body 33 is overly collapsed. Only weeds that are not in a state will have weeding and triggering action.
In this way, if the cereals are not so large, the degree of entanglement between the cereals is relatively small. It is easy to perform.

そして、分草体３３の先端よりも低い位置で分草体と接触した倒伏穀稈は、その分草体３３の傾斜下縁３３ｃに案内されて分草体３３の下縁側に導入され、前記図３，４で説明した場合と同様の、掻き込みリール３５による引き起こし、ならびに刈刃３１ａによる切断作用を受けることになる。   Then, the overlaid cereals that have come into contact with the weed body at a position lower than the tip of the weed body 33 are guided by the inclined lower edge 33c of the weed body 33 and introduced to the lower edge side of the weed body 33, as shown in FIGS. In the same manner as described in the above, it is caused by the scraping reel 35 and the cutting action by the cutting blade 31a.

〔他の実施形態例〕
