Description

この発明は、緊急停止機能を有する脱穀装置及びこれを備えたコンバインに関する。 The present invention relates to a threshing apparatus having an emergency stop function and a combine equipped with the same.

コンバインでの収穫作業においては、コンバインを走行させつつ、前部に装備された刈取機で圃場内の立毛穀稈を刈取り、この刈取穀稈をそのまま後方に移送して脱穀装置のフィードチェン及び挟持杆の間に自動的に受け渡し（自動供給）、フィードチェンにより移送しつつ脱穀を行うことが主要作業であるが、作業者により畦際を手刈り取した刈取穀稈を、フィードチェンに手動供給して脱穀を行うことも行われる。 In the harvesting operation with the combine, while the combine is traveling, the napped grain culm in the field is cut with a reaper mounted on the front, and the chopped cereal culm is transferred to the rear as it is to feed and hold the threshing device The main work is to automatically deliver (automatic supply) between the culverts and to carry out threshing while being transferred by the feed chain. Threshing is also performed.

これら刈取穀稈の自動又は手動供給中に、フィードチェンと挟持杆との間に異物（帽子や手袋、作業用具、石や木片等）が送り込まれると、機器故障等を招きかねないため、通常は脱穀装置に緊急停止手段が設けられており、この緊急停止手段の停止操作により、原動機が停止し、これに伴い脱穀装置が停止するようになっている。 During the automatic or manual supply of these harvested cereals, if foreign objects (hats, gloves, work tools, stones, wood chips, etc.) are fed between the feed chain and the holding slag, equipment failure may occur. The threshing device is provided with an emergency stop means, and by stopping the emergency stop means, the prime mover stops, and the threshing device stops accordingly.

選別室２８は、図４に示すように、上側に揺動選別棚２９が設けられており、その下側に選別方向の上手側から唐箕３０、一番移送螺旋３１、二番移送螺旋３３の順にそれぞれ軸装して構成している。符号３２は唐箕３０の送風方向を二つに分ける風向板を示している。二番揚穀装置３４は、下部が二番移送螺旋３３の終端部に接続され、上部が二番処理胴２２を有する二番処理室に連通して設けられ、二番処理室に二番物を還元する構成としている。実施例では、二番処理室は、還元された二番物を二番処理胴２２により前側に向けて移送しながら二番処理をし、選別室２８に落下、供給する構成としている。 As shown in FIG. 4, the sorting chamber 28 is provided with a swing sorting shelf 29 on the upper side, and on the lower side thereof, from the upper side of the sorting direction, the tang 30, the first transfer spiral 31, and the second transfer spiral 33.

次に、このコンバイン１０の伝動機構について、図６に示す伝動機構図に基づき具体的に説明する。図中「＞−＜」で示される部分はプーリを示しており、「＜−＞」で示される部分はスプロケットを示しており、「／−＼」で示される部分及び「｜−｜」で示される部分はギヤを示しており、プーリを繋ぐ縦線部分はベルトを示し、横線部分は回転軸を示している Next, the transmission mechanism of the combine 10 will be specifically described based on the transmission mechanism diagram shown in FIG. In the figure, a portion indicated by “>-<” indicates a pulley, a portion indicated by “<->” indicates a sprocket, and a portion indicated by “/ − \” and “|-|” The part shown shows the gear, the vertical line part connecting the pulleys shows the belt, and the horizontal line part shows the rotation axis

エンジン３５から出力される回転動力は、後方の脱穀装置１４側に伝動されるとともに、公知のコンバイン１０と同様に、例えば前方側の無断変速装置を経由して、左右のクローラ１１，１１等の走行系に伝動され、また刈取搬送装置１５に対しても伝動される。 Rotational power output from the engine 35 is transmitted to the rear threshing device 14 side and, like the known combine 10, for example, the left and right crawlers 11, 11 etc. via the front-side continuous transmission. It is transmitted to the traveling system and also transmitted to the cutting and conveying device 15.

脱穀装置１４側は、エンジン３５から出力された動力が脱穀クラッチ４７を経由して脱穀カウンタ軸４８に入力され、扱胴系統（扱胴２１側）、処理胴系統（二番処理胴２２側）、及び選別系統（選別室２８側）の３系統に分配して伝動する構成としている。 On the threshing device 14 side, the power output from the engine 35 is input to the threshing counter shaft 48 via the threshing clutch 47, and the handling cylinder system (the handling cylinder 21 side) and the processing cylinder system (the second processing cylinder 22 side). , And the sorting system (sorting chamber 28 side) is distributed and transmitted to the three systems.

扱胴系統の伝動径路は、扱胴入力軸２１ｉ、扱胴ギヤボックス２１ｇを経由して、扱胴２１、排藁チェン２５を一連の状態で伝動する構成になっている。また、選別系統の伝動経路は、唐箕３０、一番移送螺旋（一番揚穀装置３２）３１、二番移送螺旋（二番揚穀装置３４）３３、排塵ファン４９、揺動選別棚２９（揺動軸２９ｘ）、排藁カッタ３６（カッタ回転軸３６ｘ）等に順次伝動する構成としている。さらに、この選別系統の伝動経路における排塵ファン４９入力以降の伝動経路にクラッチ付ギヤボックス５０を装備して、所定速度に変速した回転動力を分岐してフィードチェン１の移送方向下流側端部に位置する後端部駆動スプロケット５５に入力する第一伝動経路Ｒ１を構成している。 The transmission path of the handling cylinder system is configured to transmit the handling cylinder 21 and the waste chain 25 in a series of states via the handling cylinder input shaft 21i and the handling gear box 21g. Further, the transmission path of the sorting system is as follows: Kara 30, first transfer spiral (first cerealing device 32) 31, second transfer spiral (second cerealing device 34) 33, dust discharge fan 49, swing sorting shelf 29 (Oscillating shaft 29x), waste cutter 36 (cutter rotating shaft 36x), etc. are sequentially transmitted. Further, a gear box 50 with a clutch is provided in the transmission path after the dust exhaust fan 49 input in the transmission path of this sorting system, and the rotational power shifted to a predetermined speed is branched to feed the downstream end of the feed chain 1 in the transfer direction. The first transmission path R <b> 1 is configured to be input to the rear end drive sprocket 55 located at the position.

このクラッチ付ギヤボックス５０は、図７に示すように、入力軸５１、排塵ファン４９の駆動軸５２、カウンタ軸５３、フィードチェン駆動軸５４の合計４本の軸を軸架した構成としている。なお、５５はフィードチェン１に係合して伝動する後端部駆動スプロケットである。入力軸５１及び排塵ファン駆動軸５２には互いに噛合するギヤ５１ｇ，５２ｇがそれぞれ軸着されている。また、カウンタ軸５３上の一端側には排塵ファン駆動軸５２のギヤ５２ｇに噛合する入力側ギヤ５６が遊嵌状態に軸装されるとともに、他端側には出力側ギヤ５７が軸方向に往復動可能なように軸着されており、入力側ギヤ５６及び出力側ギヤ５７の各対向面に互いに噛合するクラッチ爪５６ｎ，５７ｎがそれぞれ設けられている。さらに、フィードチェン駆動軸５４にはカウンタ軸５３の出力側ギヤ５７に噛合するギヤ５８が軸着されている。 As shown in FIG. 7, the clutch-equipped gear box 50 has a configuration in which a total of four shafts, that is, an input shaft 51, a drive shaft 52 of a dust exhaust fan 49, a counter shaft 53, and a feed chain drive shaft 54 are pivoted. . A rear end drive sprocket 55 is engaged with the feed chain 1 and transmitted. Gears 51 g and 52 g that mesh with each other are respectively attached to the input shaft 51 and the dust exhaust fan drive shaft 52. An input side gear 56 that meshes with the gear 52g of the dust fan drive shaft 52 is axially mounted on one end side on the counter shaft 53, and an output side gear 57 is axially mounted on the other end side. The clutch claws 56n and 57n are respectively provided on the opposing surfaces of the input side gear 56 and the output side gear 57 so as to be reciprocally movable. Further, a gear 58 that meshes with the output side gear 57 of the counter shaft 53 is attached to the feed chain drive shaft 54.

カウンタ軸５３の入力側ギヤ５６は、スプリング５６ｓにより出力側ギヤ５７に向かって付勢され、そのクラッチ爪５６ｎが出力側ギヤ５７のクラッチ爪５７ｎに噛合するようになっている。また、入力側ギヤ５６の回転を阻害せずに入力側ギヤ５６のクラッチ爪５６ｎ側の面に当接するプッシュローラ６３と、このプッシュローラ６３を支持するシフター軸６２と、このシフター軸６２の側面から突出するシフターアーム６４とを有するシフター６０を設けている。そして、シフターアーム６４をワイヤーで押し引き操作することにより、シフター軸６２をその軸心周りに回転させ、プッシュローラ６３により入力側ギヤ５６を出力側ギヤ５７から離間する方向に押し出して両クラッチ爪５６ｎ，５７ｎ相互が噛合せずに離間したクラッチ遮断（切り）状態とするか、あるいはプッシュローラの押し付けを解放して、スプリング５６ｓにより入力側ギヤ５６を出力側ギヤ５７に向かって付勢し、両クラッチ爪５６ｎ，５７ｎが噛合したクラッチ接続（入り）状態とするかを選択できるようになっている。これら入力側ギヤ５６及び出力側ギヤ５７によるクラッチはフィードチェン１への伝動を入切するものであり、第一伝動クラッチ６５を構成するものである。シフター軸６２は例えば後述の制御モータにより回動駆動する構成とすることができる。 The input side gear 56 of the counter shaft 53 is biased toward the output side gear 57 by a spring 56 s, and the clutch pawl 56 n is engaged with the clutch pawl 57 n of the output side gear 57. Further, the push roller 63 that abuts the surface of the input side gear 56 on the side of the clutch pawl 56n without impeding the rotation of the input side gear 56, the shifter shaft 62 that supports the push roller 63, and the side surface of the shifter shaft 62 A shifter 60 having a shifter arm 64 protruding from the center is provided. Then, the shifter arm 64 is pushed and pulled with a wire to rotate the shifter shaft 62 around the axis thereof, and the push roller 63 pushes the input side gear 56 away from the output side gear 57 to cause both clutch claws. 56n and 57n are not engaged with each other and are in a clutch disengaged (disengaged) state or the push roller is released and the input side gear 56 is urged toward the output side gear 57 by the spring 56s. It is possible to select whether or not the clutch engagement (engaged) state in which both clutch claws 56n and 57n are engaged is selected. These clutches by the input side gear 56 and the output side gear 57 turn on and off the transmission to the feed chain 1 and constitute the first transmission clutch 65. The shifter shaft 62 can be configured to be rotated by a control motor described later, for example.

特徴的には、フィードチェン１の前端部駆動スプロケット５９に対して、脱穀カウンタ軸４８から第二伝動経路Ｒ２を介して回転動力が伝動されるようになっている。より詳細には、前端部駆動スプロケット５９を、フィードチェン１の逆転方向（脱穀時移送方向と反対方向）にのみ回転力を伝達するワンウェイスプロケット（ワンウェイクラッチ付スプロケット）で構成するとともに、脱穀カウンタ軸４８に軸着された駆動プーリ４８ｐと、前端部駆動スプロケット５９の駆動軸３７に軸着された従動プーリ３７ｐとにベルト３８を巻き掛けて第二伝動経路Ｒ２を構成するとともに、このベルト３８を押圧・解放して駆動プーリ４８ｐと従動プーリ３７ｐとの間の伝動を入切するテンションプーリ３９を設けて、第二伝動クラッチ６６としてのテンションクラッチを構成している。したがって、後端部駆動スプロケット５５の回転によりフィードチェン１が正転方向（脱穀時移送方向）に回転しているときには、前端部駆動スプロケット５９はフリーホイール状態となる。また、テンションプーリ３９により第二伝動クラッチ６６を接続して、前端部駆動スプロケット５９に対して脱穀カウンタ軸４８からの動力を入力し、前端部駆動スプロケット５９の回転速度がフィードチェン１よりも速くなると、前端部駆動スプロケット５９は動力を伝達する状態となり、前端部駆動スプロケット５９によりフィードチェンが逆転方向に駆動される。 Characteristically, rotational power is transmitted from the threshing countershaft 48 to the front end drive sprocket 59 of the feed chain 1 via the second transmission path R2. More specifically, the front end drive sprocket 59 is constituted by a one-way sprocket (sprocket with a one-way clutch) that transmits a rotational force only in the reverse direction of the feed chain 1 (the direction opposite to the transfer direction during threshing), and a threshing countershaft A belt 38 is wound around a drive pulley 48p attached to the shaft 48 and a driven pulley 37p attached to the drive shaft 37 of the front end drive sprocket 59 to form a second transmission path R2. A tension pulley 39 as a second transmission clutch 66 is configured by providing a tension pulley 39 that turns on and off the transmission between the driving pulley 48p and the driven pulley 37p. Therefore, when the feed chain 1 is rotating in the forward rotation direction (the threshing transfer direction) by the rotation of the rear end drive sprocket 55, the front end drive sprocket 59 is in a free wheel state. Further, the second transmission clutch 66 is connected by the tension pulley 39, and the power from the threshing countershaft 48 is input to the front end drive sprocket 59, so that the rotational speed of the front end drive sprocket 59 is faster than that of the feed chain 1. Then, the front end drive sprocket 59 is in a state of transmitting power, and the feed chain is driven in the reverse direction by the front end drive sprocket 59.

他方、図１２はコンバイン１０の各種制御を行うコントローラ９０の入出力例を示している。コントローラ９０の入力側には、前・後進の切替及び走行速度の無段階変速の操作を行うためのＨＳＴ（静油圧式無段変速装置）レバー９１、停車状態で脱穀作業を行うための停車作業用ペダル５、刈取装置６を停止させて脱穀作業を行うための刈取スイッチ４６、副変速レバー９３、緊急停止スイッチ９４、詰まりセンサ９５、変速設定ダイヤル９６、穀稈センサ９７、脱穀回転センサ９８、及び変速スイッチ９９がそれぞれ接続され、操作信号や検出信号が入力される構成としている。また、コントローラ９０の出力側には、ＨＳＴ３、第一伝動クラッチ６５、第二伝動クラッチ６６、脱穀クラッチ４７、駐車ブレーキ１００、刈取クラッチ７、副変速装置８、エンジン３５がそれぞれ接続され、出力した制御信号に基づいて制御作動する構成としている。そして、コントローラ９０は、コンバイン１０の各作業に関する基準数値を記憶させており、ＣＰＵが、これらの基準数値と入力される検出情報等を比較演算しながら制御信号を出力するとしている。 On the other hand, FIG. 12 shows input / output examples of the controller 90 that performs various controls of the combine 10. On the input side of the controller 90, an HST (hydrostatic continuously variable transmission) lever 91 for performing forward / reverse switching and a stepless speed change operation, a stopping operation for performing a threshing operation in a stopped state Cutting pedal 46 for stopping the reaping device 6 and performing the threshing operation, auxiliary transmission lever 93, emergency stop switch 94, clogging sensor 95, shift setting dial 96, grain culm sensor 97, threshing rotation sensor 98, And a shift switch 99 are connected to each other, and an operation signal and a detection signal are input. Moreover, HST3, the 1st transmission clutch 65, the 2nd transmission clutch 66, the threshing clutch 47, the parking brake 100, the mowing clutch 7, the subtransmission apparatus 8, and the engine 35 are connected to the output side of the controller 90 and output. The control operation is performed based on the control signal. The controller 90 stores reference numerical values relating to each operation of the combine 10, and the CPU outputs control signals while comparing and calculating these reference numerical values and input detection information and the like.

かかるコントローラにより、コンバイン１０の緊急時の制御がなされる。すなわち、コンバイン１０には、緊急時にすぐ押圧操作ができるように、フィードチェン１の搬送始端部の脱穀装置カバー表面の押し易い位置（図１参照）に緊急停止スイッチ９４が設けられており、その操作によりコントローラ９０に緊急信号を入力できる構成としている。また、詰まりセンサ９５が、刈取搬送装置１５とフィードチェン１との穀稈引継ぎ部位と、フィードチェン１の終端部と排藁チェン２５との排藁の受継位置に設けられ、搬送穀稈（排藁）の詰まりを監視する構成としており、詰まりが発生するとコントローラ９０に詰まり情報が即座に入力される構成としている。 Such a controller controls the combine 10 in an emergency. That is, the combine 10 is provided with an emergency stop switch 94 at a position where the threshing device cover surface of the feed start end of the feed chain 1 can be easily pressed (see FIG. 1) so that it can be immediately pressed in an emergency. An emergency signal can be input to the controller 90 by operation. In addition, a clogging sensor 95 is provided at the grain takeover part of the cutting and conveying device 15 and the feed chain 1, and at the position where the end of the feed chain 1 and the waste chain 25 are inherited. The claw is monitored for clogging, and clogging information is immediately input to the controller 90 when clogging occurs.

そして、コントローラ９０は、脱穀時には脱穀クラッチ４７及び第一伝動クラッチ６５を接続し、第二伝動クラッチ６６を遮断する制御信号を発してコンバイン１０を脱穀作業状態とするのに対して、緊急停止スイッチ９４又は詰まりセンサ９５から情報が入力されると、エンジン３５に緊急停止の制御信号を出力してエンジン３５をストップすると同時に、脱穀クラッチ４７及び第一伝動クラッチ６５を遮断し、第二伝動クラッチ６６を接続するようにそれぞれ制御信号を出力する。これにより、回転する扱胴２１の慣性力は脱穀カウンタ軸４８から選別系統の伝動経路に伝わるが、第一伝動クラッチ６５が遮断しているため第一伝動経路Ｒ１には伝わらなくなり、フィードチェン１に対する正転駆動系の動力供給は停止される。一方、回転する扱胴２１の慣性力は脱穀カウンタ軸４８及び第二伝動経路Ｒ２を介してフィードチェン１の前端部駆動スプロケット５９に伝達され、フィードチェン１に対して脱穀時移送方向とは反対向きの動力が与えられ、フィードチェン１は逆転されるか又は停止する。よって、停止操作後も異物が搬送されるといった事態を防止でき、もって、機器故障及びその拡大の防止、並びに異物除去作業の容易化等を図ることができる。しかも、本実施形態では、専用の原動機を必要とせずに、簡素な構成で逆転駆動系を構成することができるといった利点や、緊急停止時には、第一伝動クラッチに６５より正転駆動系の動力の伝動を切るため、第二伝動経路Ｒ２を介してフィードチェン１を停止させる又は脱穀時移送方向とは反対向きに駆動するための負荷が少なくて済むといった利点がある。 The controller 90 connects the threshing clutch 47 and the first transmission clutch 65 at the time of threshing and issues a control signal to shut off the second transmission clutch 66 to put the combine 10 in the threshing work state, whereas the emergency stop switch 94 or when the information is input from the clogging sensor 95, an emergency stop control signal is output to the engine 35 to stop the engine 35. At the same time, the threshing clutch 47 and the first transmission clutch 65 are disconnected, and the second transmission clutch 66 is output. Control signals are output so as to connect the two. As a result, the inertial force of the rotating barrel 21 is transmitted from the threshing countershaft 48 to the transmission path of the sorting system, but is not transmitted to the first transmission path R1 because the first transmission clutch 65 is disconnected. The power supply of the forward drive system to is stopped. On the other hand, the inertial force of the rotating barrel 21 is transmitted to the front end drive sprocket 59 of the feed chain 1 through the threshing countershaft 48 and the second transmission path R2, and is opposite to the feed direction for the feed chain 1 during threshing. Directional power is applied and feed chain 1 is reversed or stopped. Therefore, it is possible to prevent a situation in which foreign matter is conveyed even after the stop operation, and thus it is possible to prevent equipment failure and its expansion, and facilitate foreign matter removal work. Moreover, in this embodiment, there is an advantage that the reverse drive system can be configured with a simple configuration without requiring a dedicated prime mover, and the power of the forward drive system is higher than 65 in the first transmission clutch at the time of emergency stop. Therefore, there is an advantage that the load for stopping the feed chain 1 through the second transmission path R2 or driving in the direction opposite to the transfer direction during threshing can be reduced.

緊急停止後に通常状態に復帰させる場合、専用の復帰機構及び操作を容易しても良いが、脱穀クラッチ４７が接続する操作等、脱穀作業を再開するような操作を行ったとき、コントローラ９０は脱穀回転センサ９８等によりその操作に伴う信号を受けて、第二伝動クラッチ６６を遮断する制御信号を出力する構成とすると、脱穀装置１４の再始動を自動で容易に行うことができるため好ましい。 When returning to the normal state after an emergency stop, a dedicated return mechanism and operation may be facilitated. However, when an operation that resumes the threshing operation, such as an operation that the threshing clutch 47 is connected, the controller 90 threshs. It is preferable to receive a signal accompanying the operation by the rotation sensor 98 or the like and to output a control signal for shutting off the second transmission clutch 66 because the threshing device 14 can be automatically restarted easily.

（第２の形態）
第２の形態は、図８に示すように、第二伝動経路Ｒ２を脱穀カウンタ軸４８から分岐するのではなく、扱胴入力軸２１ｉから分岐してその回転動力をフィードチェン１の前端部駆動スプロケット５９に対して入力するようになっている点で上述の第１の形態と相違するものであり、その他は第１の形態と同様の構成となっている。このように第二伝動経路Ｒ２は、慣性力を駆動に利用できる限り、任意の伝動経路から分岐することができるものである。 (Second form)
In the second embodiment, as shown in FIG. 8, the second transmission path R2 is not branched from the threshing countershaft 48, but is branched from the barrel input shaft 21i to drive the rotational power to the front end portion of the feed chain 1. This is different from the first embodiment described above in that it is input to the sprocket 59, and the other configuration is the same as that of the first embodiment. Thus, the second transmission path R2 can be branched from any transmission path as long as the inertial force can be used for driving.

（第３の形態）
第３の形態は、図９に示すように、第一伝動経路Ｒ１にトルクリミッタ７０を介在させたものである。そして、コントローラ９０は、脱穀時には脱穀クラッチ４７及び第一伝動クラッチ６５を接続し、第二伝動クラッチ６６を遮断する制御信号を発してコンバイン１０を脱穀作業状態とするのに対して、緊急停止スイッチ９４又は詰まりセンサ９５から情報が入力されると、エンジン３５に緊急停止の制御信号を出力してエンジン３５をストップすると同時に、第一伝動クラッチ６５は遮断せずに脱穀クラッチ４７を遮断し、第二伝動クラッチ６６を接続するようにそれぞれ制御信号を出力する。これにより、回転する扱胴２１の慣性力は脱穀カウンタ軸４８及び第二伝動経路Ｒ２を介してフィードチェン１の前端部駆動スプロケット５９に伝達され、フィードチェン１に対して脱穀時移送方向とは反対向きの動力が与えられる。同時に、回転する扱胴２１の慣性力は脱穀カウンタ軸４８から選別系統の伝動経路及び第一伝動経路Ｒ１を介して、フィードチェン１の後端部駆動スプロケット５５にも伝達され、フィードチェン１に対して脱穀時移送方向の動力が与えられる。その結果、フィードチェン１に正逆両方の動力が与えられる。ただしこのとき、トルクリミッタ７０には設定トルク以上のトルクが発生してスリップし、当該トルクリミッタ７０において第一伝動経路Ｒ１における伝動は遮断されるため、フィードチェン１に対して第一伝動経路Ｒ１からの正転動力の供給はなされず、第二伝動経路Ｒ２を介して逆転動力が供給され、フィードチェン１は逆転されるか又は停止することになる。 (Third form)
In the third mode, as shown in FIG. 9, a torque limiter 70 is interposed in the first transmission path R1. The controller 90 connects the threshing clutch 47 and the first transmission clutch 65 at the time of threshing and issues a control signal to shut off the second transmission clutch 66 to put the combine 10 in the threshing work state, whereas the emergency stop switch 94 or when the information is input from the clogging sensor 95, the emergency stop control signal is output to the engine 35 to stop the engine 35. At the same time, the first transmission clutch 65 is not shut off but the threshing clutch 47 is shut off. Control signals are output so that the two transmission clutches 66 are connected. As a result, the inertial force of the rotating barrel 21 is transmitted to the front end drive sprocket 59 of the feed chain 1 via the threshing countershaft 48 and the second transmission path R2, and what is the transfer direction during threshing with respect to the feed chain 1? Opposite power is provided. At the same time, the inertial force of the rotating barrel 21 is also transmitted from the threshing countershaft 48 to the rear end drive sprocket 55 of the feed chain 1 via the transmission path of the sorting system and the first transmission path R1. On the other hand, power in the transfer direction during threshing is given. As a result, both forward and reverse power are applied to the feed chain 1. However, at this time, torque exceeding the set torque is generated in the torque limiter 70 and slips, and transmission in the first transmission path R1 is interrupted in the torque limiter 70, so that the first transmission path R1 with respect to the feed chain 1 is interrupted. The forward rotation power is not supplied from the rear side, but the reverse rotation power is supplied through the second transmission path R2, and the feed chain 1 is reversely rotated or stopped.

したがって、第一伝動経路Ｒ１による正転駆動系の動力の伝動をクラッチにより積極的に切ることなく、第二伝動クラッチ６６を接続するだけでトルクリミッタ７０の作用により即時にフィードチェン１を停止させる又は脱穀時移送方向とは反対向きに駆動することができ、フィードチェン１の正転・逆転の切り替えをより高速に行うことができるとともに、その切り替え制御も簡素となる。 Therefore, the feed chain 1 is immediately stopped by the action of the torque limiter 70 only by connecting the second transmission clutch 66 without actively disconnecting the power of the forward drive system by the first transmission path R1 by the clutch. Or it can drive in the direction opposite to the transfer direction at the time of threshing, and the forward / reverse switching of the feed chain 1 can be performed at a higher speed, and the switching control is also simplified.

なお、本第３の形態においては、第１の形態における第一伝動クラッチ６５は設けなくても良く、また設けた場合には緊急停止時に第１の形態と同様に脱穀クラッチ４７と同時に遮断することができる。 In the third embodiment, the first transmission clutch 65 in the first embodiment may not be provided, and if provided, the emergency transmission is shut off simultaneously with the threshing clutch 47 as in the first embodiment. be able to.

（第４の形態）
第４の形態は、第１の形態において、第二伝動経路Ｒ２のプーリ３７ｐ，４８ｐ及びベルト３８間の動摩擦力よりも、第一伝動経路Ｒ１の分岐元の伝動経路におけるプーリ及びベルト（第一伝動経路Ｒ１の少なくとも一部を複数のプーリ及びこれに巻き掛けられたベルトにより構成した場合には、これにしても良い）間の動摩擦力がある程度弱くなるように、いずれか一方又は両方のベルトテンション等を設定したものである。そして、コントローラ９０は、脱穀時には脱穀クラッチ４７及び第一伝動クラッチ６５を接続し、第二伝動クラッチ６６を遮断する制御信号を発してコンバイン１０を脱穀作業状態とするのに対して、緊急停止スイッチ９４又は詰まりセンサ９５から情報が入力されると、エンジン３５に緊急停止の制御信号を出力してエンジン３５をストップすると同時に、第一伝動クラッチ６５は遮断せずに脱穀クラッチ４７を遮断し、第二伝動クラッチ６６を接続するようにそれぞれ制御信号を出力する。これにより、回転する扱胴２１の慣性力は脱穀カウンタ軸４８及び第二伝動経路Ｒ２を介してフィードチェン１の前端部駆動スプロケット５９に伝達され、フィードチェン１に対して脱穀時移送方向とは反対向きの動力が与えられる。同時に、回転する扱胴２１の慣性力は脱穀カウンタ軸４８から選別系統の伝動経路及び第一伝動経路Ｒ１を介して、フィードチェン１の後端部駆動スプロケット５５にも伝達され、フィードチェン１に対して脱穀時移送方向の動力が与えられる。その結果、フィードチェン１に正逆両方の動力が与えられる。ただしこのとき、前述の動摩擦力差が存在するため、第二伝動経路Ｒ２を構成するプーリ３７ｐ，４８ｐ及びベルト３８間は滑らずに、第一伝動経路Ｒ１の分岐元の伝動経路を構成するプーリ及びベルト間がスリップすることになり、その結果として第一伝動経路Ｒ１における伝動は遮断されるため、フィードチェン１に対して第一伝動経路Ｒ１からの正転動力の供給はなされず、第二伝動経路Ｒ２を介して逆転動力が供給され、フィードチェン１は逆転されるか又は停止することになる。 (4th form)
The fourth form is the same as the first form in that the pulleys and belts in the transmission path of the branching source of the first transmission path R1 (the first belt) (the first belt) are more than the dynamic friction force between the pulleys 37p, 48p of the second transmission path R2 and the belt 38. If at least a part of the transmission path R1 is constituted by a plurality of pulleys and a belt wound around the pulleys, this may be used. The tension is set. The controller 90 connects the threshing clutch 47 and the first transmission clutch 65 at the time of threshing and issues a control signal to shut off the second transmission clutch 66 to put the combine 10 in the threshing work state, whereas the emergency stop switch 94 or when the information is input from the clogging sensor 95, the emergency stop control signal is output to the engine 35 to stop the engine 35. At the same time, the first transmission clutch 65 is not shut off but the threshing clutch 47 is shut off. Control signals are output so that the two transmission clutches 66 are connected. As a result, the inertial force of the rotating barrel 21 is transmitted to the front end drive sprocket 59 of the feed chain 1 via the threshing countershaft 48 and the second transmission path R2, and what is the transfer direction during threshing with respect to the feed chain 1? Opposite power is provided. At the same time, the inertial force of the rotating barrel 21 is also transmitted from the threshing countershaft 48 to the rear end drive sprocket 55 of the feed chain 1 via the transmission path of the sorting system and the first transmission path R1. On the other hand, power in the transfer direction during threshing is given. As a result, both forward and reverse power are applied to the feed chain 1. However, at this time, since the above-described dynamic frictional force difference exists, the pulleys constituting the transmission path that is the branching source of the first transmission path R1 without slipping between the pulleys 37p and 48p and the belt 38 constituting the second transmission path R2. And the belt slips. As a result, the transmission in the first transmission path R1 is interrupted, so that the forward rotation power from the first transmission path R1 is not supplied to the feed chain 1, and the second transmission path R1 is not supplied. Reverse power is supplied via the transmission path R2, and the feed chain 1 is reversely rotated or stopped.

したがって、第一伝動経路Ｒ１による正転駆動系の動力の伝動をクラッチにより積極的に切ることなく、第二伝動クラッチ６６を接続するだけで、第二伝動経路Ｒ２を構成するプーリ３７ｐ，４８ｐ及びベルト３８間は滑らずに、第一伝動経路Ｒ１の分岐元の伝動経路を構成するプーリ及びベルト間が滑ることにより、即時にフィードチェン１を停止させる又は脱穀時移送方向とは反対向きに駆動することができ、フィードチェン１の正転・逆転の切り替えをより高速に行うことができるとともに、その切り替え制御及び伝動機器の構成も簡素となる。 Therefore, the pulleys 37p, 48p constituting the second transmission path R2 and the pulleys 37p, 48p constituting the second transmission path R2 can be obtained only by connecting the second transmission clutch 66 without actively disconnecting the power of the forward drive system by the first transmission path R1. Without slipping between the belts 38, the feed chain 1 is immediately stopped by sliding between the pulleys and the belts constituting the branching transmission path of the first transmission path R1, or driven in the direction opposite to the transfer direction during threshing. Thus, the forward / reverse switching of the feed chain 1 can be performed at a higher speed, and the switching control and the configuration of the transmission device are simplified.

なお、本第４の形態においては、第１の形態における第一伝動クラッチ６５は設けなくても良く、また設けた場合には緊急停止時に第１の形態と同様に脱穀クラッチ４７と同時に遮断することができる。 In the fourth embodiment, the first transmission clutch 65 in the first embodiment may not be provided, and if provided, the first transmission clutch 65 is shut off simultaneously with the threshing clutch 47 at the time of emergency stop as in the first embodiment. be able to.

（第５の形態）
第５の形態は、図１０に示すように、エンジン３５の動力をフィードチェン１へ伝動する第一伝動経路Ｒ１は設けずに、エンジン３５とは別個にフィードチェン１の後端部駆動スプロケット５５を直接に駆動する電動機７１を設けた点で上述の第１の形態と相違するものであり、その他は第１の形態と同様の構成となっている。そして、コントローラ９０は、脱穀時には脱穀クラッチ４７を接続し、電動機７１を駆動し、第二伝動クラッチ６６を遮断する制御信号を発してコンバイン１０を脱穀作業状態とするのに対して、緊急停止スイッチ９４又は詰まりセンサ９５から情報が入力されると、エンジン３５に緊急停止の制御信号を出力してエンジン３５をストップすると同時に、脱穀クラッチ４７を遮断し、電動機７１を駆動停止し、第二伝動クラッチ６６を接続するようにそれぞれ制御信号を出力する。これにより、電動機７１が駆動停止しているためフィードチェン１に対する正転駆動系の動力供給は停止される。一方、回転する扱胴２１の慣性力は脱穀カウンタ軸４８及び第二伝動経路Ｒ２を介してフィードチェン１の前端部駆動スプロケットに伝達され、フィードチェン１に対して脱穀時移送方向とは反対向きの動力が与えられ、フィードチェン１は逆転されるか又は停止する。 (5th form)
In the fifth embodiment, as shown in FIG. 10, the rear end drive sprocket 55 of the feed chain 1 is provided separately from the engine 35 without providing the first transmission path R1 for transmitting the power of the engine 35 to the feed chain 1. This is different from the first embodiment described above in that an electric motor 71 for directly driving is provided, and the other configuration is the same as that of the first embodiment. And the controller 90 connects the threshing clutch 47 at the time of threshing, drives the electric motor 71, emits a control signal to shut off the second transmission clutch 66, and puts the combine 10 into the threshing work state, whereas the emergency stop switch 94 or when information is input from the clogging sensor 95, an emergency stop control signal is output to the engine 35 to stop the engine 35. At the same time, the threshing clutch 47 is shut off, the driving of the motor 71 is stopped, and the second transmission clutch. Control signals are output so as to be connected to each other. Thereby, since the drive of the electric motor 71 is stopped, the power supply of the forward drive system to the feed chain 1 is stopped. On the other hand, the inertial force of the rotating barrel 21 is transmitted to the front end drive sprocket of the feed chain 1 via the threshing countershaft 48 and the second transmission path R2, and is opposite to the feed direction during the threshing. The feed chain 1 is reversed or stopped.

このように、扱胴２１及び第二伝動経路Ｒ２への動力を供給するエンジン３５とは別個に、正転駆動系をなす電動機７１を設けて、正転駆動系の入切を電動機７１の入切により行う構成としたことにより、正転駆動系の入切のための装置構成及び切換制御が簡素となる。 Thus, separately from the engine 35 that supplies power to the handling cylinder 21 and the second transmission path R2, the electric motor 71 that constitutes the normal rotation drive system is provided, and the on / off of the normal rotation drive system is turned on / off. By adopting the configuration that is performed by turning off, the device configuration and switching control for turning on and off the forward rotation drive system are simplified.

（第６の形態）
第６の形態は、図１１に示すようにフィードチェン１の支持部、つまりフィードチェンの前端部駆動スプロケット５９及び後端部駆動スプロケット５５を支持するレール状部分７５，７６を、移送方向上流側に位置する上流側チェン支持部７５と移送方向下流側に位置する下流側チェン支持部７６とに分割し、両者を左右方向に沿う回動軸７７を介して連結し、上流側チェン支持部７５の前端側にシリンダからなる往復駆動装置７８を接続し、この往復駆動装置７８により上流側チェン支持部７５を下流側チェン支持部７６側の端部の回動軸７７を支点として挟持杆２から離間する方向及び挟持杆２に近づく方向に回動可能に構成したものである。そして、コントローラ９０は、脱穀時には往復駆動装置７８により上流側チェン支持部７５を挟持杆２に近づく方向に移動させた状態として、当該上流側チェン支持部７５におけるフィードチェン１と挟持杆２との間で穀稈を挟持搬送するのに対して、緊急停止スイッチ９４又は詰まりセンサ９５から情報が入力されると、往復駆動装置７８により上流側チェン支持部７５が挟持杆２から離間する方向に回動されて、フィードチェン１における上流側チェン支持部７５に位置する部分を挟持杆２から離間させる。よって、本第６の形態によれば、緊急停止時にフィードチェンと挟持杆２との間に挟まれた異物を除去し易くなる。特に、上述の第１〜第５の形態においては、緊急停止時にはフィードチェン１は逆転されるか又は停止し、異物が上流側チェン支持部７５におけるフィードチェン１と挟持杆２との間に位置する可能性が高くなるため、本第６の形態を組み合わせるのは好ましい。 (Sixth form)
In the sixth embodiment, as shown in FIG. 11, the support part of the feed chain 1, that is, the rail-like parts 75 and 76 that support the front end drive sprocket 59 and the rear end drive sprocket 55 of the feed chain are arranged upstream in the transfer direction. Are divided into an upstream chain support portion 75 located at the downstream side and a downstream chain support portion 76 located downstream in the transfer direction, and both are connected via a rotating shaft 77 along the left-right direction. A reciprocating drive device 78 composed of a cylinder is connected to the front end side of the shaft, and by this reciprocating drive device 78, the upstream side chain support portion 75 is used as a fulcrum from the rotation shaft 77 at the end on the downstream side chain support portion 76 side. It is configured to be rotatable in the direction of separating and the direction of approaching the holding rod 2. And the controller 90 is the state which moved the upstream chain support part 75 in the direction which approaches the clamping rod 2 by the reciprocating drive device 78 at the time of threshing, and the feed chain 1 and the clamping rod 2 in the said upstream chain support part 75 are said. When the information is input from the emergency stop switch 94 or the clogging sensor 95, the upstream chain support portion 75 is rotated by the reciprocating drive device 78 in a direction away from the clamping rod 2. It is moved and the part located in the upstream chain | strand support part 75 in the feed chain 1 is spaced apart from the clamping rod 2. FIG. Therefore, according to the sixth embodiment, it is easy to remove foreign matter sandwiched between the feed chain and the clamping rod 2 at the time of emergency stop. In particular, in the first to fifth embodiments described above, the feed chain 1 is reversed or stopped during an emergency stop, and the foreign matter is positioned between the feed chain 1 and the clamping rod 2 in the upstream chain support portion 75. It is preferable to combine the sixth embodiment because the possibility of doing so increases.
