The chain rail 9 is attached along the outside. The feed chain 7 is provided so as to be guided along the guide surface (upper surface) of the chain rail 9 so as to be able to guide, and the stock source of the cereals is placed between the feed chain 7 and the squeeze 13 arranged facing the upper side. It is set as the structure which clamps and conveys in the state which inserted the tip side in the processing chamber 14. FIG. The threshing device 3 omits a detailed drawing of the inside of the machine body, but threshs the cocoon spikes that are inserted into the handling chamber 14 by pivoting the handling cylinder, and selects below. A chamber is arranged so that the cereals dropped and supplied from the upper handling chamber 14 are selected.

そして、脱穀装置３は、図１、及び図２に示した実施例の場合、前記フィードチェン７の移動通路より外側に間隔を隔てて、穀稈株元の移動通路に沿わせて穀稈の株元を下側から支えて案内する株元案内杆１５を、後部の排藁位置まで延長して設けた構成としている。 In the case of the embodiment shown in FIG. 1 and FIG. 2, the threshing device 3 is arranged along the movement path of the cereal stock along the movement path of the cereal stock source with an interval outside the movement path of the feed chain 7. The stock company guide bar 15 that supports and guides the stock company from the lower side is provided so as to extend to the rear evacuation position.

このように構成すれば、前記株元案内杆１５は、穀稈丈の極端に長い長稈がフィードチェン７と挟扼杆１３とによって挟持されて搬送される工程で機体より外側に突出する株元部を支えて垂れ下がりを防止しながら案内することができる。 If comprised in this way, the said stock former guide rod 15 is the stock | stump which protrudes outside from a body in the process by which the long cocoon of an extremely long grain height is clamped by the feed chain 7 and the clamp 13 and conveyed. It can be guided while supporting the base part and preventing drooping.

つぎに、本件発明の主要部となる穀稈株元ガイド１０について、実施例を具体的に説明する。
まず、穀稈株元ガイド１０は、図２、及び図３に示すように、その始端部をフィードチェン７の搬送始端部より前に位置させ、しかも、図１，及び図４に示すように、その始端部をフィードチェン７の搬送始端部より低い位置に配置して設け、更に、中間部分から後部に至るガイド部分１０ａを、フィードチェン７より外方へ張出しながら、該チェン７の搬送方向（搬送径路）に沿わせて上方に向けて湾曲させた形状に構成している。そして、穀稈株元ガイド１０は、図３、及び図４に示すように、始端部から分岐した取付杆部分１０ｂを、調節板１６に固着し、その調節板１６を支持部材１１に、前記取付杆部分１０ｂの杆方向、及び上下方向（調節長孔１７の方向）に調節自在に取り付け、更に、その支持部材１１の後部を、前記チェンレール９に連結して支持した構成としている。 Next, an embodiment of the cereal strain source guide 10 which is a main part of the present invention will be specifically described.
First, as shown in FIGS. 2 and 3, the cereal stock source guide 10 has its start end positioned in front of the transfer start end of the feed chain 7, and as shown in FIGS. 1 and 4. The feed end 7 is arranged at a position lower than the feed start end of the feed chain 7, and the guide portion 10 a extending from the intermediate portion to the rear is extended outward from the feed chain 7, and the feed direction of the chain 7 is extended. It is configured in a shape curved upward along the (conveyance path). As shown in FIG. 3 and FIG. 4, the cereal base guide 10 is attached to the adjustment plate 16 with the attachment rod portion 10 b branched from the start end, and the adjustment plate 16 is attached to the support member 11. The mounting rod portion 10b is mounted so as to be adjustable in the vertical direction and the vertical direction (the direction of the adjustment slot 17), and the rear portion of the support member 11 is connected to and supported by the chain rail 9.

このように、穀稈株元ガイド１０は、フィードチェン７が搬送する穀稈の挟持部位より外側へ隔たった穀稈株元部を下側から受け止めて支えながら案内することができる構成となっており、始端部を低い位置に設けることにより、搬送穀稈に対する障害がほとんどない。更に、穀稈株元ガイド１０は、前述のように、チェンレール９に取り付けることによって、フィードチェンの開放時にはフィードチェン７やその構成部材と一体に回動できるから有効であるが、その点については、後述する。そして、穀稈株元ガイド１０は、フィードチェン７の搬送方向に沿わせて上方に向けて湾曲させた形状にガイド部分１０ａを構成しているから、フィードチェン７と挟扼杆１３で挟持されて機外に長く突出した株元部分を支えることができるから、穀稈の搬送姿勢を乱すことはほとんどなく、姿勢を常に一定に保って整然と案内できる特徴がある。 As described above, the cereal stock source guide 10 is configured to be able to guide and support the cereal stock base portion that is spaced outward from the sandwiched portion of the cereal stock carried by the feed chain 7 from below. In addition, by providing the starting end portion at a low position, there is almost no obstacle to the transporting culm. Furthermore, as described above, the cereal stock source guide 10 is effective because it can be rotated integrally with the feed chain 7 and its constituent members when the feed chain is opened by being attached to the chain rail 9. Will be described later. And the cereal stock former guide 10 comprises the guide part 10a in the shape curved upward along the conveyance direction of the feed chain 7, and is clamped by the feed chain 7 and the clamp 13 Because it can support the stock base part that protrudes long outside the machine, there is almost no disturbance in the posture of carrying the cereals, and it has the feature that it always keeps the attitude constant and guides it neatly.

つぎに、刈取搬送装置４は、図１、及び図２に示すように、基部を車体１上の懸架台１８に上下回動自在に枢着して支持した刈取フレーム２０に、前部低位置の分草杆２１と、その背後に上下方向斜めに配置した穀稈引起し装置２２と、下方位置の刈取装置２３と、刈取穀稈を後部上方に搬送する穀稈搬送装置２４と、扱深さ調節装置６とをそれぞれ取付けて伝動可能に構成している。そして、扱深さ調節装置６は、既に広く知られているから、具体的な図示は省略したが、穀稈供給口２の前方に垂下させた扱深さセンサの検出情報に基づいて制御する自動扱深さ調節制御装置によって長稈、短稈の差に基づいて稈身方向に移動調節される構成となっている。この場合、搬送穀稈は、長稈、短稈の差に応じて稈身方向に移動調節しながら、扱室１４に挿入する穀稈の穂部位置を、極力、扱胴の一定の位置（脱粒効率が高い部位）に接当させて効率良く脱粒ができるようにしている。 Next, as shown in FIG. 1 and FIG. 2, the cutting and conveying device 4 has a front lower position on a cutting frame 20 that pivotally supports the base portion on a suspension base 18 on the vehicle body 1 so as to be pivotable up and down. Chopsticks 21, a grain raising device 22 disposed obliquely in the vertical direction behind it, a reaping device 23 at a lower position, a cereal carrying device 24 for conveying the harvested cereal to the rear upper side, The height adjusting device 6 is attached to each other so that transmission is possible. And since the handling depth adjustment apparatus 6 is already widely known, although the specific illustration was abbreviate | omitted, it controls based on the detection information of the handling depth sensor hung down ahead of the grain supply port 2 It is configured to be moved and adjusted in the slimming direction based on the difference between the long and short lengths by the automatic handling depth adjustment control device. In this case, the transporting culm is adjusted to move in the slimming direction according to the difference between the long culm and the short culm, and the groin head position to be inserted into the handling chamber 14 is set to a certain position of the handling cylinder as much as possible. It is made to come into contact with the part where the degranulation efficiency is high) so that the degranulation can be performed efficiently.

このように、扱深さ調節装置６は、穀稈の穂部位置を扱室１４の一定位置に合わせて調節しながら搬送して、終端部からフィードチェン７の搬送始端部に引継がせる構成となっている。実施例の場合、前記フィードチェン７の始端部内側には平行に配置したシンクロチェン２５（刈取側の搬送速度にシンクロさせた引継ぎ用のチェン）を設け、搬送穀稈を円滑に引継ぐように構成している。 In this way, the handling depth adjusting device 6 conveys while adjusting the head position of the cereals to a certain position of the handling chamber 14, and can take over from the terminal portion to the conveying start end portion of the feed chain 7. It has become. In the case of the embodiment, the feed chain 7 is provided with a synchro chain 25 (takeover chain synchronized to the cutting speed) on the inner side of the starting end so as to smoothly take over the transported culm. is doing.

そして、既に説明した穀稈株元ガイド１０と、前記扱深さ調節装置６との位置関係は、図５に示すように、平面視で扱深さ調節装置６の搬送終端部よりも穀稈株元ガイド１０の始端部が内側に位置する構成としている。 The positional relationship between the cereal stock guide 10 already described and the handling depth adjusting device 6 is higher than that of the conveying terminal of the handling depth adjusting device 6 in a plan view as shown in FIG. The starting end of the stock guide 10 is configured to be located inside.

このように構成すれば、穀稈株元ガイド１０は、刈取側から脱穀側への引継ぎ時に、ガイド部材が抵抗になることはなく、引継ぎ搬送性能が向上し、搬送穀稈がガイド１０の内側に入ることもなくなる利点がある。 If comprised in this way, at the time of the takeover from the harvesting side to the threshing side, the culm stock guide 10 does not become a resistance of the guide member, the takeover conveyance performance is improved, and the conveyed culm is inside the guide 10. There is an advantage that you can not enter.

更に、前記穀稈株元ガイド１０は、前記扱深さ調節装置６が制御信号に基づいて扱深さ調節される範囲の外側（後方）に配置した構成としているから、扱深さ調節作用時に障害となることを避けて、扱深さ調節装置６がスムーズに移動できる。 Furthermore, since the said cereal stock former guide 10 is set as the structure arrange | positioned on the outer side (rear) of the range in which the handling depth adjustment apparatus 6 is adjusted based on a control signal, at the time of handling depth adjustment effect | action The handling depth adjusting device 6 can move smoothly while avoiding an obstacle.

そして、穀稈株元ガイド１０は、図４に基づいて既に説明したように、前記調節板１６に設けている３個の調節長孔１７を利用して、上下方向、及び前後方向に調節できるから、前記扱深さ調節装置６を最も深く調節する極短稈の場合、始端部が上方位置になるように調節すると、深扱ぎ時でも作用させることが可能となる。そして、該穀稈株元ガイド１０は、前記扱深さ調節装置６を最も深く調節する極短稈の場合、始端部が上方位置（穀稈の株元部位より上方）になるように調節すると、深扱ぎ時でも作用させることが可能となる。逆に、穀稈株元ガイド１０は、扱深さ調節装置６を最も深く調節した短稈の場合に、始端部が穀稈の株元より下方位置になるように調節すると、深扱ぎ時には作用させないようにすることができるものとなっている。 And as already demonstrated based on FIG. 4, the cereal stock former guide 10 can be adjusted to the up-down direction and the front-back direction using the three adjustment long holes 17 provided in the said adjustment board 16. As shown in FIG. Therefore, in the case of an extremely short rod that adjusts the handling depth adjusting device 6 most deeply, if the starting end is adjusted to the upper position, it can be operated even during deep handling. And, in the case of the ultra-short cocoon that adjusts the handling depth adjusting device 6 most deeply, the cereal culm stock guide 10 is adjusted so that the starting end is in an upper position (above the cereal base part). It is possible to work even when deeply handled. On the contrary, the grain culm stock guide 10 adjusts the start end portion to a position below the stock base of the grain culm when the handling depth adjusting device 6 is most deeply adjusted. It can be made not to act.

つぎに、実施例に係るコンバイン５は、刈取搬送装置４の左側を、回動自由に車体１側に軸装している回動軸に連結して構成しており、従来から広く知られている刈取オープン回動して、刈取搬送装置４のメンテナンスや清掃を行うことができるものとなっている。更に、実施例のコンバイン５は、フィードチェン７の搬送始端部側を縦軸でコンバイン車体に回動自在に枢着してフィードチェンの開放ができる構成としている。 Next, the combine 5 according to the embodiment is configured by connecting the left side of the cutting and conveying device 4 to a rotating shaft that is rotatably mounted on the vehicle body 1 side, and has been widely known from the past. The cutting and opening of the cutting cutter can be rotated to perform maintenance and cleaning of the cutting and conveying device 4. Further, the combine 5 according to the embodiment is configured such that the feed chain 7 can be opened by pivotally mounting the feed start end side of the feed chain 7 on the combine vehicle body with the vertical axis.

このように、実施例に係るコンバイン５は、刈取オープン時に刈取搬送装置４を車体１の左側に回動しても刈取搬送装置４の一部分が、穀稈株元ガイド１０に接触したり、衝突することはなく、破損等の事故が起こることはない。又、上述の構成によってフィードチェンの開放回動をさせても、そのフィードチェン７の前側から側部外側に設けた穀稈株元ガイド１０がチェンレール９と一体になってオープン回動するが、回動範囲に障害物はなく、破損することはない。 Thus, the combine 5 which concerns on an Example, even if the harvesting conveyance apparatus 4 rotates to the left side of the vehicle body 1 at the time of a harvesting opening, a part of harvesting conveyance apparatus 4 contacts the cereal stock former guide 10, or it collides. No accidents such as damage will occur. Further, even if the feed chain is opened and rotated by the above-described configuration, the cereal stock former guide 10 provided on the outside of the side portion from the front side of the feed chain 7 is integrated with the chain rail 9 and opened and rotated. , There is no obstacle in the rotation range and it will not be damaged.

又、穀稈株元ガイド１０は、刈取搬送装置４を刈高調節時や収納時に刈取フレーム２０の基部を回動支点にして前部を上方に回動させてもその回動範囲内から外側に設けているから、接触して破損することはない。 In addition, the cereal stock base guide 10 can be moved outside the rotation range even if the front part is rotated upward with the base part of the harvesting frame 20 as a pivotal fulcrum at the time of cutting height adjustment or storage. Because it is provided in, it will not be damaged by contact.

このように、実施例に係る穀稈株元ガイド１０は、周囲にある回動する部材の回動範囲を避け、ガイド１０自体が回動する範囲にも他の装置がないように、配置しているから、接触や障害が発生することはなく破損から守られて、安全に長期間の使用に耐えることができる。 As described above, the cereal stockholder guide 10 according to the embodiment is arranged so as to avoid the rotation range of the rotating members around and avoid other devices in the range in which the guide 10 itself rotates. Therefore, it can be protected from damage without causing contact or failure, and can withstand long-term use safely.
