Are interlocked so that the devices 21, 21,... Are driven and rotated through the lateral transmission shaft 39.

左側前穂先係止搬送装置２６Ｒ１、中央側穂先係止搬送装置２６Ｃ及び右側穂先係止搬送装置２６Ｌの上方には、上部穂先係止搬送装置４０Ｒ，４０Ｃ，４０Ｌ（右側上部穂先係止搬送装置４０Ｒ，中央側上部穂先係止搬送装置４０Ｃ，左側上部穂先係止搬送装置４０Ｌ）を設けて長稈に対する適応性をもたせるように構成している。 Above the left front tip locking transport device 26R1, the center side tip locking transport device 26C, and the right head tip locking transport device 26L, there is an upper tip locking transport device 40R, 40C, 40L (right upper tip locking transport device 40R). , A center-side upper tip locking / conveying device 40C, and a left upper tip locking / conveying device 40L) are provided so as to be adaptable to long rods.

図７に示すように、右側前穂先係止搬送装置２６Ｒ１と上部穂先係止搬送装置４０Ｒとの間隔Ａと、左側穂先係止搬送装置２６Ｌと上部穂先係止搬送装置４０Ｌとの間隔Ｂとの関係において、間隔Ｂより間隔Ａの間隔を大きくすることにより、右側２条、中央側２条をまとめて刈取搬送する多量穀稈の穂先側部と中間部を係止して安定よく確実に搬送することができる。 As shown in FIG. 7, the distance A between the right front tip locking transport device 26R1 and the upper tip locking transport device 40R and the distance B between the left head tip locking transport device 26L and the upper tip locking transport device 40L. In the relationship, by making the interval A larger than the interval B, the tip side and intermediate part of the large-scale cereals that are harvested and conveyed together on the right two and the central two are locked and conveyed stably and reliably. can do.

左側穂先係止搬送装置２６Ｌの搬送速度よりも、右側穂先係止搬送装置２６Ｒの搬送速度を速くするように構成しておくと、右側の搬送距離が長い上、途中から左搬送、中搬送が合流するため、合流後の穀稈の流れが安定し搬送がスムーズに行える。また、右側穂先係止搬送装置２６Ｒにおいて、右側前穂先係止搬送装置２６Ｒ１の搬送速度よりも、右側後穂先係止搬送装置２６Ｒ２の搬送速度を速くすることによって、前から後への引継ぎ後の穀稈の停滞がなく、安定した良好な連続搬送が可能となる。 If the conveying speed of the right tip locking transport device 26R is set to be faster than the transport speed of the left tip locking transport device 26L, the right transport distance is longer and the left transport and middle transport from the middle Because of merging, the flow of cereals after merging is stable and can be carried smoothly. Further, in the right-hand tip locking transport device 26R, by making the transport speed of the right rear-tip locking transport device 26R2 faster than the transport speed of the right front-tip locking transport device 26R1, it is possible to perform the post-handover from the front to the rear. There is no stagnation of cereals and stable continuous conveyance is possible.

人文字型搬送方式においては、脱穀部への引継ぎ時、機体の左側へ集められるため、左側搬送距離が短く、右側搬送距離が長くなる構成となり、刈り始めは左側搬送分の少量の穀稈、刈り終わりは右側搬送分の少量の穀稈が脱穀部へ引き継がれることになり、扱ぎ残しなどが生じる不安定な搬送があった。かかる課題を解決するためには、右側後穂先係止搬送装置２６Ｒ２の搬送速度よりも、右側前穂先係止搬送装置２６Ｒ１の搬送速度を速くすることによって、安定した搬送が可能となる。 In the human character type conveying system, it is gathered to the left side of the machine when taking over to the threshing part, so the left side conveying distance is short and the right side conveying distance is long. At the end of cutting, a small amount of cereal for the right-hand side was transferred to the threshing section, and there was an unstable transfer that left unhandled items. In order to solve such a problem, stable conveyance can be achieved by increasing the conveyance speed of the right front tip locking mechanism 26R1 than the conveyance speed of the right rear tip locking mechanism 26R2.

また、人文字型搬送方式において、右側株元挟持搬送装置２５Ｒ、右側前穂先係止搬送装置２６Ｒ１、上部穂先係止搬送装置４０Ｒのそれぞれの搬送速度が、２５Ｒ＜２６Ｒ１＜４０Ｒの順序で速くなるように設定しておくと、極長稈作物の刈取作業であっても、穂先側を先行させながら搬送でき、穂先遅れなどによる脱穀負荷の軽減を図ることができる。 Further, in the human character type conveyance system, the conveyance speeds of the right stock holding and conveying apparatus 25R, the right front-tip locking and conveying apparatus 26R1, and the upper tip locking and conveying apparatus 40R are increased in the order of 25R <26R1 <40R. If set in this way, even in the operation of cutting extremely long culm crops, it can be conveyed while leading the tip side, and the threshing load due to the tip end delay can be reduced.

図１０及び図１１に示す実施例について説明すると、図例における掻込搬送装置２３は、掻込スターホイル２３ａの上側で、株元挟持搬送装置２５を挟む上下に掻込ベルト２３ｂ１，２３ｂ２を配設したもので、しかも、下段の掻込ベルト（第２掻込ベルト）２３ｂ２は、上段の掻込ベルト（第１掻込ベルト）２３ｂ１より入口を広く拡開させた構成としている。下段の掻込ベルトによる掻込作用によって短稈適応性が向上し、掻込２段による掻込力がアップし確実に掻込搬送することができる。 The embodiment shown in FIGS. 10 and 11 will be described. In the example shown in FIG. 10, the scraping and transporting device 23 is provided with the scraping belts 23 b 1 and 23 b 2 on the upper and lower sides of the stock holding and transporting device 25 on the upper side of the stirring star wheel 23 a. In addition, the lower stage take-up belt (second take-up belt) 23b2 has a configuration in which the entrance is wider than the upper stage take-up belt (first take-up belt) 23b1. The scoring action by the lower stapling belt improves the adaptability of the short punch, and the scooping force by the second stapling is increased, so that it can be transported reliably.

図１２に示す実施例では、右側の上部穂先係止搬送装置４０Ｒを右側前穂先係止搬送装置２６Ｒ１と略同一長さに構成して２段に設け、右側株元挟持搬送装置２５Ｒと併せて３段構成とし、各々を同一の搬送駆動軸４１で駆動する構成としている。３段搬送構成であるため、穀稈の搬送作用が安定し、右上部穂先搬送の作用範囲が長くなるので、長稈であっても搬送姿勢が良好に保持できる。 In the embodiment shown in FIG. 12, the right upper head tip locking and conveying device 40R is configured to be substantially the same length as the right front head tip locking and conveying device 26R1, and is provided in two stages, together with the right stock holding and conveying device 25R. A three-stage configuration is used, and each is driven by the same transport drive shaft 41. Since it has a three-stage transport configuration, the transporting action of the cereal buds is stable, and the action range of the upper right tip transfer is long, so that the transport posture can be satisfactorily maintained even with a long spear.

図１３〜図１５に示す実施例は、前株元挟持搬送装置２５Ｒ１を、更に前後に２分割して一次株元挟持搬送装置（以下一次株元チエンと云う）２５Ｒ１ａと二次株元挟持搬送装置（以下二次株元チエンと云う）２５Ｒ１ｂとからなるように構成し、一次株元チェン２５Ｒ１ａを下側に、二次株元チェン２５Ｒ１ｂを上側にして上下２段に配設すると共に、上下２段の中間スプロケット４３，４３によりラップさせ、前側の一次株元チェン２５Ｒ１ａを掻込スターホイル２３ａの直上に接近させて前部スプロケット４４との間に券回している。そして、二次株元チェン２５Ｒ１ｂは、前穂先搬送駆動軸３５より駆動し、中間スプロケット４３，４３により一次株元チェン２５Ｒ１ａを駆動する構成になっている。株元チェンが単一構成のものでは、掻込スターホイルに負荷がかかると、チェンが張られて搬送通路が狭くなったり、チェンレールより離れている部分があるため、穀稈の姿勢によりチェンが傾き脱線することがあった。株元チェンを上記のように２分割することで、チェンレールより離脱することなく、いかなる条件下でも搬送通路幅が一定になる。しかも、前側の株元チェンの高さが低くなったため、短稈のキャッチングが向上することになる。 In the embodiment shown in FIGS. 13 to 15, the former stock holding and transporting device 25R1 is further divided into two parts in the front and rear, and the primary stock holding and transporting device (hereinafter referred to as the primary stock holding chain) 25R1a and the secondary stock holding and transporting device. Device (hereinafter referred to as the secondary stock chain) 25R1b, and is arranged in two upper and lower stages with the primary stock chain 25R1a on the bottom and the secondary stock chain 25R1b on the top. Wrapped by two stages of intermediate sprockets 43, 43, the primary stock chain 25R1a on the front side is brought close to the top of the stir-up star wheel 23a and is wound around the front sprocket 44. The secondary stock chain 25R1b is driven from the forehead transport drive shaft 35, and the primary stock chain 25R1a is driven by the intermediate sprockets 43 and 43. If the stock chain has a single structure, when the stir-up star wheel is loaded, the chain is stretched and the conveyance path becomes narrower or there is a part away from the chain rail. Sometimes tilted and derailed. By dividing the stock chain into two parts as described above, the width of the conveyance path becomes constant under any conditions without being separated from the chain rail. Moreover, since the height of the front lines based chain is lowered, so that the calibration Tsu quenching of short culm is improved.

なお、かかる実施例において、上記中間スプロケット４３，４３を異径とし、両株元チェンの搬送速度を、前側の一次株元チェンより後側の二次株元チェンが速くなるように設定しておくことで、搬送距離の長い右側搬送部と短い左側搬送部との合流タイミングを容易に合わすことができる。また、分草幅の広い右搬送部の搬送速度を速くすることにより、横刈り時など穀稈流量が多いときでも層圧を薄くできる。また、上記とは逆に、前側の株元チェン速度より、後側の株元チェン速度を遅くすることも可能であるが、この場合には、後側株元チェンでの搬送厚さがアップし、途切れのない連続搬送が可能となる。 In this embodiment, the intermediate sprockets 43 and 43 have different diameters, and the conveying speed of both stock chains is set so that the secondary stock chain on the rear side is faster than the primary stock chain on the front side. By setting, it is possible to easily match the merging timing of the right conveyance unit having a long conveyance distance and the short left conveyance unit. In addition, by increasing the conveyance speed of the right conveyance section having a wide weed width, the laminar pressure can be reduced even when the cereal flow rate is large, such as during horizontal cutting. Contrary to the above, it is possible to make the rear stock chain speed slower than the front stock chain speed. In this case, however, the transport thickness in the rear stock chain is increased. Therefore, continuous conveyance without interruption is possible.

図１６は、右側の後株元挟持搬送装置２５Ｒ２の構成例を示すもので、搬送チェン４５の終端直線部（イ）より前方に挟持杆４６のホルダー４７を設置し、そして、このホルダー４７を所定のα角前方に向けて偏位させた構成としている。これにより、脱穀部との引継ぎ部のスペースを大きくとることができ、引継案内ガイド等の配置が容易にできる。引継ぎ部分が広くとれることにより、詰りなどに対するトラブル解消が容易となる。また、挟持杆４６をチェン側に押す前後の摺動ロッド４８，４８をチェンに対しての角度θ１，θ２を同一角度に設定することで、くの字に屈折したチェンを同じ強さで挟持でき、前後の摺動ロッドのコゼがなくスムースに作動する。更に、前記ホルダー４７をチェン４５のくの字屈曲作用範囲Ｈの中心部に位置するよう配置することで、搬送チェンの入口と出口での挟持力が略同じにでき、搬送性能を高めることができる。 FIG. 16 shows a configuration example of the right rear stock holding apparatus 25R2 on the right side. A holder 47 of a holding rod 46 is installed in front of the terminal straight line portion (a) of the transfer chain 45, and this holder 47 is attached to the holder 47. It is configured to be deviated toward a predetermined α angle front. Thereby, the space of the takeover part with a threshing part can be taken large, and arrangement | positioning of a takeover guide guide etc. can be performed easily. Since the takeover portion can be widened, troubles such as clogging can be easily solved. In addition, by setting the angles θ1 and θ2 of the sliding rods 48, 48 before and after the holding rod 46 is pushed to the chain side to the same angle, the chain refracted in the shape of a dog is clamped with the same strength. It can be operated smoothly without the front and rear sliding rods. Further, by arranging the holder 47 so as to be positioned at the center of the dog-shaped bending action range H of the chain 45, the holding force at the inlet and outlet of the transfer chain can be made substantially the same, and the transfer performance can be improved. it can.

また、挟持杆４６の先端部４６ａとホルダー４７のロッド４８側の側面４７ａが略平行となるように構成しておくと、搬送チェン４５始端の入口部で挟持杆４６が平行に押すため、動きがスムースで、少量から多量まで搬送量が変化しても挟持杆がより速く追従でき、稈こぼれなどの発生を極減することができる。 Further, if the tip end portion 46a of the holding rod 46 and the side surface 47a on the rod 48 side of the holder 47 are configured to be substantially parallel, the holding rod 46 pushes in parallel at the entrance portion at the start end of the transfer chain 45. Is smooth, so that even if the conveyance amount changes from a small amount to a large amount, the holding rod can follow faster and the occurrence of spillage can be minimized.

図７及び図８に示すように、コンバインに搭載されたグレンタンＧにおいて、グレンタンク内の籾センサの信号によってタンク上に設けた３つの告知ランプＲ１，Ｒ２，Ｒ３が籾量に応じて順次点灯する構成としている。例えば、籾が空の場合（ａ）から３／５程度溜まると１つのランプＲ１が点灯（ｂ）し、４／５程度溜まると２つのランプＲ１，Ｒ２が点灯（ｃ）する。そして、満杯になると全部のランプＲ１，Ｒ２，Ｒ３が点灯（ｄ）するようにしておくと、タンク内の籾量を逐次オペレータや周囲の補助者に速やかに告知することができる。また、別実施例として、この３つのランプＲ１，Ｒ２，Ｒ３を「青」「黄」「赤」３色に色分けし、「青」が点灯している場合はタンク内を空とし、タンク内に籾がある程度溜まると「黄」が点灯し、満杯になると「赤」が点灯して告知する手段を採用してもよい。更に、他の実施例として、１つの告知ランプで、点灯間隔を変えることによってタンク内の籾量を告知するように構成することもできる。例えば、タンク内の籾がある程度の量に達すると、この時点からランプの点滅が始まるようにし、最初は点滅間隔を長く（粗く）し、量が増すごとに点滅間隔を短くしてゆき、満杯になると最も短い点滅間隔にしてオペレータへの告知を速く促すようにする。 As shown in FIGS. 7 and 8, in the Glentan G mounted on the combine, the three notification lamps R1, R2, and R3 provided on the tank are sequentially turned on according to the amount of drought by the signal of the dredge sensor in the Glen tank. It is configured to do. For example, when the kite is empty, the lamp R1 is turned on (b) when about 3/5 is accumulated from (a), and the two lamps R1 and R2 are turned on (c) when about 4/5 is accumulated. If all the lamps R1, R2, and R3 are turned on (d) when they are full, the amount of soot in the tank can be promptly notified to the operator and surrounding assistants. As another example, the three lamps R1, R2, and R3 are color-coded into “blue”, “yellow”, and “red”, and when “blue” is lit, the tank is emptied, A means may be adopted in which “yellow” is lit when a certain amount of soot accumulates and “red” is lit when full. Furthermore, as another embodiment, a single notification lamp can be configured to notify the amount of soot in the tank by changing the lighting interval. For example, when the amount of soot in the tank reaches a certain level, the lamp starts blinking from this point, and at the beginning, the blinking interval is lengthened (coarse) and the blinking interval is shortened as the amount increases. Then, the operator should promptly notify the operator with the shortest blinking interval.
