なお、刈取部変速装置刈取部変速装置52により刈取部4の作業速度を独自に変更するだけでなく、前記ミッションケース44内の副変速装置により変速される走行装置2の走行速度に刈取部4の作業速度を対応させる構成とすることも可能である。そして、前記受動割プーリ64は、その回転軸74を一方向回転伝達クラッチ(ワンウェイクラッチ)75を介して軸受51に取付け、前記油圧式無段主変速装置45が逆回転を伝達するとき、この逆回転を刈取部4に伝達しないように構成している。
The reaping part transmission 52 independently shifts the working speed of the reaping part 4 with respect to the traveling speed of the traveling device 2 and increases the working speed of the reaping part 4 during the harvesting of the fallen cereal.
In addition, not only the working speed of the cutting unit 4 is independently changed by the cutting unit transmission unit 52 but also the cutting unit 4 is changed to the traveling speed of the traveling unit 2 that is shifted by the auxiliary transmission unit in the transmission case 44. It is also possible to adopt a configuration in which these work speeds are made to correspond. The passive split pulley 64 is attached to the bearing 51 through a one-way rotation transmission clutch (one-way clutch) 75, and when the hydraulic continuously variable main transmission 45 transmits reverse rotation, The reverse rotation is not transmitted to the cutting unit 4.

しかして、後側株元搬送装置17および後側穂先搬送装置18の終端部と前記穀稈供給装置30の搬送チエン32の始端部の間には引継搬送装置76を設ける。引継搬送装置76は前記支持フレーム39にチエン案内レール77の中間部を取付け、チエン案内レール77の前後両端に一対の横軸回転の受動歯車78、78を取付け、該受動歯車78、78に引継搬送チエン(前側供給搬送チェン)80を掛け回す。81は別途設けた案内歯車であり、テンション歯車を兼用する。そして、引継搬送チエン80には前記ギヤケース56より突出す回転軸82に固定の駆動歯車83を噛合わせる。したがって、引継搬送装置76の搬送速度も油圧式無段主変速装置45により走行装置2の走行速度と比例して変速され、また、前記刈取部変速装置52により刈取部4の作業速度に同調して変速される。なお、穀稈供給装置30は、エンジン43の一定回転が常時伝達されているので、搬送速度は一定である。しかして、前記引継搬送チエン80の始端部は、後側株元搬送装置17の搬送チエン19の終端部下方に臨ませ、引継搬送チエン80の上方位置には案内ガイド85を設ける。案内ガイド85は、その始端部は後側株元搬送装置17および後側穂先搬送装置18の終端部近傍に臨ませ、終端部は引継搬送チエン80の始端部の上方に望ませ、かつ、引継搬送チエン80の始端部上方に位置する作用位置と、引継搬送チエン80の始端部上方より離れた退避位置との間移動自在に構成し、穀稈を案内するだけでなく、メンテナンスも容易に行えるようにしている。案内ガイド85は、具体的には、穀稈の搬送方向と平行(前後方向)の軸部材により形成し、案内ガイド85の始端部は穀稈の搬送方向と交差する方向に屈曲させて屈曲部に形成し、該屈曲部を前記後側穂先搬送装置18の案内ガイド27の取付部材26の終端部に回転自在かつ搬送方向と交差する方向に摺動自在に取付け、案内ガイド85は引継搬送チエン80の始端部上方に位置するようにバネにより付勢している。   Thus, a takeover conveying device 76 is provided between the terminal end of the rear stock transporting device 17 and the rear tip conveying device 18 and the starting end of the conveying chain 32 of the cereal supply device 30. The take-up and transfer device 76 has an intermediate portion of the chain guide rail 77 attached to the support frame 39, and a pair of laterally rotating passive gears 78 and 78 attached to the front and rear ends of the chain guide rail 77. The transfer chain (front supply transfer chain) 80 is wound around. 81 is a guide gear provided separately, which also serves as a tension gear. The take-up conveyance chain 80 is engaged with a fixed drive gear 83 on a rotary shaft 82 protruding from the gear case 56. Therefore, the transfer speed of the takeover transfer device 76 is also changed in proportion to the drive speed of the travel device 2 by the hydraulic continuously variable main transmission 45, and is synchronized with the work speed of the cut portion 4 by the reaping portion transmission 52. To change the speed. In addition, since the constant rotation of the engine 43 is always transmitted, the conveyance speed is constant in the grain supply device 30. Accordingly, the start end of the takeover transport chain 80 faces below the end of the transport chain 19 of the rear stock transporter 17, and a guide guide 85 is provided above the takeover transport chain 80. The guide guide 85 has its start end facing the vicinity of the end of the rear stock transport device 17 and the rear tip transport device 18, and the end is desired above the start end of the takeover transport chain 80 and takes over. It is configured to be movable between an action position located above the start end of the transport chain 80 and a retracted position away from above the start end of the takeover transport chain 80, and not only guides the cereal but also facilitates maintenance. I am doing so. Specifically, the guide guide 85 is formed by a shaft member that is parallel (front-rear direction) to the conveying direction of the corn straw, and the start end portion of the guide guide 85 is bent in a direction intersecting with the conveying direction of the corn straw. The bent portion is attached to the terminal portion of the attachment member 26 of the guide guide 27 of the rear tip conveying device 18 so as to be rotatable and slidable in a direction crossing the conveying direction. It is urged by a spring so as to be positioned above the starting end portion of 80.

Sometimes it is a relationship. That is, the transfer speed B of the take-up transfer apparatus 76 is in the vicinity of the middle between the maximum speed of the transfer speed C of the rear side stock transfer apparatus 17 and the rear side tip transfer apparatus 18 and the transfer speed A (constant speed) of the cereal supply apparatus 30. The maximum speed is set.

It is.

次に作用を述べる。本発明の実施の形態は以上の構成であり、エンジン43を始動させると、この回転が油圧式無段主変速装置45に伝達され、運転席の操作レバー87の操作により油圧式無段主変速装置45が回転数を無段階に変速して走行装置2のミッションケース44に伝達して機体を前進させ、他方、ミッションケース44から刈取部入力プーリ46に伝達されて刈取部4の各部を作動させ、分草体5により分草し、分草された穀稈を引起装置6により引起し、引起した穀稈を掻込装置7により掻込みながら根元側を刈刃8により切断し、刈取られた穀稈の根元側は前側株元搬送装置9により穂先側は前側穂先搬送装置10により引継点まで搬送され、引継点まで搬送された穀稈の株元は後側株元搬送装置17の縦軸回転の歯車と回転する搬送チエン19と挾扼杆20により挾持搬送され、穂先側は案内ガイド27により案内されて後側穂先搬送装置18の搬送ラグ23により搬送される。   Next, the operation will be described. The embodiment of the present invention has the above-described configuration. When the engine 43 is started, this rotation is transmitted to the hydraulic continuously variable main transmission 45, and the hydraulic continuously variable main transmission is operated by operating the operation lever 87 in the driver's seat. The device 45 changes the rotation speed steplessly and transmits it to the transmission case 44 of the traveling device 2 to advance the machine body. On the other hand, it is transmitted from the transmission case 44 to the cutting portion input pulley 46 to operate each portion of the cutting portion 4. The cereals were weeded by the weeding body 5, the cereals that were weeded were raised by the pulling device 6, and the root side was cut by the cutting blade 8 while being scraped by the scraping device 7, and was cut. The root side of the cereal is transported to the takeover point by the front side stock transport device 10 by the front side stock transport device 9, and the stock of the cereal that has been transported to the takeover point is the vertical axis of the rear side stock transport device 17. Rotating gear and rotating conveyor chain 1 And the 挾扼 rod 20 is clamped transported, the tip side is conveyed by the conveying lugs 23 of the guide has been rear tip conveying device 18 by guides 27.

そして、後側株元搬送装置17および後側穂先搬送装置18の終端部で、横軸回転の受動歯車78に掛け回された引継搬送装置76の引継搬送チエン80と該引継搬送チエン80の上方の案内ガイド85の間に引継ぎ、引継搬送装置76は穀稈供給装置30の供給搬送チエン32に引継いて脱穀装置3の脱穀室31に供給し、回転する扱胴92により脱穀し、脱穀物を選別して機外に取出し、脱穀済の排藁は排藁搬送装置94により排藁処理部95に搬送して処理する。前記の場合、穀稈は後側株元搬送装置17および後側穂先搬送装置18の終端部では起立状態であるが、案内ガイド27により案内されて横倒しにされながら横軸回転の引継搬送チエン80に引継ぐので、穀稈の搬送姿勢の乱れがなく、そのまま、穀稈を横倒し状態の最終姿勢で穀稈供給装置30の供給搬送チエン32に引継ぐので、穀稈の落下を防止して引継を確実にする。また、引継搬送装置76が穀稈供給装置30の供給搬送チエン32と平行であって、かつ内側に位置しているから、側面視重合させることができて、引継が確実となるだけでなく、特に短穀稈の搬送が確実となる。また、引継搬送装置76の引継搬送チエン80の始端部は、後側株元搬送装置17の終端部下方に臨ませ、また、穀稈供給装置30の供給搬送チエン32の始端部は引継搬送チエン80の終端部下方に臨ませているから、各引継部における引継は良好に行われる。   Then, at the terminal ends of the rear stock transport device 17 and the rear tip transport device 18, the takeover transport chain 80 of the takeover transport device 76 wound around the passive gear 78 rotating on the horizontal axis and above the takeover transport chain 80. Is taken over between the guide guides 85, the take-up conveying device 76 takes over the supply conveying chain 32 of the cereal supply device 30 and supplies it to the threshing chamber 31 of the threshing device 3, threshing by the rotating barrel 92, Sorted and taken out of the machine, the threshed waste is transported to the waste processing unit 95 by the waste transporting device 94 and processed. In the above case, the cereal is in a standing state at the terminal ends of the rear stock transporting device 17 and the rear tip transporting device 18, but it is guided by the guide guide 27 and turned sideways while being turned sideways. Therefore, there is no disturbance in the posture of the cereal conveyance, and the cereal is laid sideways and taken over to the supply conveyance chain 32 of the cereal supply device 30 in the final posture. To. In addition, since the take-up conveyance device 76 is parallel to the supply conveyance chain 32 of the cereal supply device 30 and is located on the inner side, the side view polymerization can be performed, and not only the takeover is ensured, The transport of short grain rice cake is ensured. In addition, the start end of the takeover conveyance chain 80 of the takeover conveyance device 76 faces the lower end of the rear stock transporter 17 and the start end of the supply conveyance chain 32 of the cereal supply device 30 is the takeover conveyance chain. Since it faces under the terminal part of 80, the takeover in each takeover part is performed satisfactorily.

前記引継搬送チエン80の駆動歯車83は、前後の受動歯車78の間の側部に設けたギヤケース56より突出する回転軸82に設けているから、駆動歯車83と前後の受動歯車78とのそれぞれの位置関係を正確に配置することができ、確実に作動させる。また、ギヤケース56の入力プーリ54の部分にクラッチ41を設けているので、刈取部4を停止させると引継搬送装置76も停止し、またスタートの同調もなされて引継が良好となり、穀稈の搬送姿勢も良好となる。また、ギヤケース56はステー42により脱穀装置3の前板に固定しているから、引継搬送装置76と後側株元搬送装置17および後側穂先搬送装置18と穀稈供給装置30との位置関係も固定でき、作動が確実となる。   Since the drive gear 83 of the take-up conveyance chain 80 is provided on the rotary shaft 82 protruding from the gear case 56 provided on the side portion between the front and rear passive gears 78, the drive gear 83 and the front and rear passive gears 78 respectively. It is possible to accurately arrange the positional relationship of and to operate reliably. Further, since the clutch 41 is provided at the input pulley 54 portion of the gear case 56, when the cutting unit 4 is stopped, the take-up conveying device 76 is also stopped, and the start-up is synchronized so that the take-over is good, and the corn straw carrying posture Will also be good. Further, since the gear case 56 is fixed to the front plate of the threshing device 3 by the stay 42, the positional relationship among the takeover conveyance device 76, the rear side stock conveyance device 17, the rear side tip conveyance device 18 and the cereal supply device 30. Can be fixed, and the operation is reliable.

そして、油圧式無段主変速装置45により走行装置2を停止させると刈取部4および引継搬送装置76は停止するので、作業が確実となり操作性が向上し、また、ミッションケース44内の副変速装置により機体を停止させたときは、油圧式無段主変速装置45から刈取部4および引継搬送装置76に回転を伝達しているので、刈取部4等により搬送途中の穀稈を脱穀装置3に供給できる。しかして、油圧式無段主変速装置45は逆回転をミッションケース44に伝達するが、刈取部変速装置52の受動割プーリ64は一方向回転伝達クラッチ75を介して軸受51に取付けた回転軸74取付けているので、刈取部4および引継搬送装置76等に逆回転が伝達されるのを防止している。このとき、回転軸74は軸受51に設けた一方向回転伝達クラッチ75に取付けているので、メンテナンスを容易に行なえる。   Then, when the traveling device 2 is stopped by the hydraulic continuously variable main transmission 45, the cutting unit 4 and the take-over transport device 76 are stopped, so that the work is ensured and the operability is improved, and the sub-shift in the transmission case 44 is improved. When the machine is stopped by the device, the rotation is transmitted from the hydraulic continuously variable main transmission 45 to the harvesting unit 4 and the take-up conveying device 76, so that the threshing device 3 removes cereal grains that are being conveyed by the harvesting unit 4 or the like. Can supply. Thus, the hydraulic continuously variable main transmission 45 transmits the reverse rotation to the transmission case 44, but the passive split pulley 64 of the cutting part transmission 52 is a rotary shaft attached to the bearing 51 via the one-way rotation transmission clutch 75. Since 74 is attached, it is possible to prevent reverse rotation from being transmitted to the cutting unit 4 and the takeover conveyance device 76. At this time, since the rotating shaft 74 is attached to the one-way rotation transmission clutch 75 provided in the bearing 51, maintenance can be easily performed.

しかして、圃場の穀稈が倒伏状態の場合は、走行速度に対して刈取部4の作業速度が遅いと、充分に倒伏穀稈を引上げることができないことがあるが、刈取部変速装置52を作動させることにより刈取部4へ伝達する回転を上昇させると、確実に作業が行なえる。   Therefore, when the grain culm in the field is in the lying state, if the working speed of the cutting unit 4 is slow relative to the traveling speed, the lying grain culm may not be able to be pulled up sufficiently, but the cutting unit transmission 52 When the rotation transmitted to the mowing unit 4 is raised by operating the, the work can be performed reliably.

即ち、通常は、油圧式無段主変速装置45により走行装置2と刈取部4は比例して変速されるが、刈取部変速装置52により独自に刈取部4の作業速度と後側株元搬送装置17、後側穂先搬送装置18および株引継搬送装置76の搬送速度を変更して穀稈の状態に応じた作業速度を選択できる。   That is, normally, the traveling device 2 and the cutting unit 4 are shifted in proportion by the hydraulic continuously variable main transmission 45, but the operating speed of the cutting unit 4 and the rear stock transport are independently set by the cutting unit transmission 52. The working speed according to the state of the cereal can be selected by changing the conveying speed of the apparatus 17, the rear tip conveying apparatus 18 and the stock transfer conveying apparatus 76.

この場合、穀稈供給装置30の搬送速度Aと、引継搬送装置76の搬送速度Bと、後側株元搬送装置17および後側穂先搬送装置18の搬送速度Cとは、A<B<Cの関係にすると、後側株元搬送装置17および後側穂先搬送装置18から引継搬送装置76への引継ぎで減速され、引継搬送装置76から穀稈供給装置30への引継ぎで減速され、穀稈供給装置30に向けて搬送されるに従い穀稈の量が多くなって厚くなり、搬送速度も次第に遅くなるので搬送姿勢が良好となる。   In this case, the transport speed A of the grain supply device 30, the transport speed B of the takeover transport device 76, and the transport speed C of the rear side stock transport device 17 and the rear tip transport device 18 are A <B <C. In this relationship, the speed is reduced by taking over from the rear stock transporter 17 and the rear tip transporter 18 to the takeover transport device 76, decelerated by the takeover from the takeover transport device 76 to the cereal supply device 30, and As the amount of the cereal increases as it is conveyed toward the supply device 30 and becomes thicker, and the conveyance speed gradually decreases, the conveyance posture is improved.

即ち、刈取部変速装置52を作動させることにより刈取部4へ伝達する回転を上昇させて倒伏穀稈の作業が確実容易となるばかりでなく、これに対応して後側搬送装置17、18および株元引継搬送装置76の搬送速度を変更して確実に搬送できるという効果を奏する。   That is, by operating the cutting part transmission device 52, the rotation transmitted to the cutting part 4 is raised so that the work of the overlaid cereals is made easy, and correspondingly, the rear conveying devices 17, 18 and There exists an effect that it can convey reliably by changing the conveyance speed of the stock takeover conveyance apparatus 76.

しかして、前記穀稈供給装置30は、脱穀装置の上部カバー34を持ち上げて挾扼杆33を上動させて供給搬送チエン32の上面を開放し、次に、駆動歯車37への伝動の接続を外し、案内レール35の終端と機体側とを固定するロック装置97のロックを解除してから、縦柱38中心に案内レール35の終端部を外側回動させて、穀稈供給装置30および脱穀装置3の脱穀室31のメンテナンスを行なう。   Thus, the cereal supply device 30 lifts the upper cover 34 of the threshing device to move the heel 33 upward to open the upper surface of the supply conveyance chain 32, and then connect the transmission to the drive gear 37. And unlocking the lock device 97 that fixes the end of the guide rail 35 and the machine body side, and then rotating the end of the guide rail 35 outward about the vertical column 38 to Maintenance of the threshing chamber 31 of the threshing device 3 is performed.
