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 is configured as described above. 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 continuously changes the rotation speed and transmits the transmission to the transmission case 44 of the traveling device 2 to advance the machine body. On the other hand, the transmission is transmitted from the transmission case 44 to the cutting unit input pulley 46 to operate the respective units of the cutting unit 4. Then, weeding was carried out by the weeding body 5, the weeded culm was raised by the raising device 6, and the raised cereal culm was cut by the cutting blade 8 while being scraped by the scraping device 7, and cut. The root side of the cereal culm is conveyed to the takeover point by the front-side conveyer 10 by the front-side conveyer 9, and the base of the cereal culm conveyed to the transfer-over point is the vertical axis of the rear-side conveyer 17 Rotating gear and rotating transport 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 end of the rear stock transfer device 17 and the rear spike transfer device 18, the transfer transfer chain 80 of the transfer transfer device 76 and the upper side of the transfer transfer chain 80 of the transfer transfer device 76 wrapped around the passive gear 78 rotating in the horizontal axis. Is transferred between the guide guides 85 and the transfer conveyance device 76 is transferred to the supply conveyance chain 32 of the grain culm supply device 30 and supplied to the threshing room 31 of the threshing device 3, threshed by the rotating handling cylinder 92, and threshed. The sorted straw is taken out of the machine, and the threshed straw is transported by a straw transporting device 94 to a straw processing unit 95 for processing. In the above case, the grain culm is in an upright state at the end portions of the rear stock transfer device 17 and the rear spike transfer device 18, but while being guided by the guide 27 and lying down, the takeover transfer chain 80 having a horizontal axis rotation. Since the transfer of the grain stalk is not disturbed, the grain stalk is taken over to the supply and transport chain 32 of the grain stalk supply device 30 in the final posture in a state of lying down, so that the grain stalk is prevented from falling and the transfer is ensured. To In addition, since the transfer device 76 is parallel to the supply transfer chain 32 of the grain culm supply device 30 and is located inside, the polymerization can be performed in a side view, and not only the transfer is ensured, but also particularly, Short culm can be transported reliably. Also, the start end of the transfer chain 80 of the transfer unit 76 faces below the end of the rear stock transfer unit 17, and the start end of the supply chain 32 of the grain culm supply unit 30 is the transfer chain. Since the end faces 80 are located below the end portion, the handover at each handover section is performed well.
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。   The drive gear 83 of the transfer chain 80 is provided on the rotating shaft 82 protruding from the gear case 56 provided on the side between the front and rear passive gears 78, so that the drive gear 83 and the front and rear passive gears 78 are respectively provided. Can be arranged accurately, and can be reliably operated. In addition, since the clutch 41 is provided at the input pulley 54 of the gear case 56, when the reaping unit 4 is stopped, the takeover conveying device 76 is also stopped. Is also 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 between the take-over transport device 76, the rear stock transport device 17, and the rear spike transport device 18 and the grain culm supply device 30. Can be fixed, and the operation is assured.
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。   When the traveling device 2 is stopped by the hydraulic continuously variable main transmission device 45, the mowing unit 4 and the takeover transport device 76 are stopped, so that the work is assured and the operability is improved. When the machine is stopped by the device, the rotation is transmitted from the hydraulic stepless main transmission 45 to the reaping unit 4 and the take-over transporting device 76. Can be supplied. 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 reaper transmission 52 is connected to the rotating shaft mounted on the bearing 51 via the one-way rotation transmission clutch 75. The attachment 74 prevents the reverse rotation from being transmitted to the reaper 4, the transfer device 76 and the like. At this time, since the rotating shaft 74 is attached to the one-way rotation transmitting clutch 75 provided on 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。   In the case where the culm in the field is in the lying state, if the working speed of the reaper 4 is slower than the traveling speed, it may not be possible to sufficiently pull the laid culm. When the rotation transmitted to the reaper 4 is increased 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 reaping unit 4 are shifted in proportion to each other by the hydraulic stepless main transmission device 45, but the working speed of the reaping unit 4 and the rear stock transfer are independently controlled by the reaping unit transmission device 52. By changing the transport speed of the device 17, the rear spike transport device 18 and the stock takeover transport device 76, it is possible to select a work speed according to the state of the grain culm.
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 transfer speed A of the grain culm supply device 30, the transfer speed B of the transfer transfer device 76, and the transfer speed C of the rear stock transfer device 17 and the rear tip transfer device 18 are A <B <C. In the relationship, the speed is reduced by taking over from the rear stock transfer device 17 and the rear ear transfer device 18 to the transfer device 76, and is reduced by taking over from the transfer device 76 to the grain stalk supply device 30, and As the grain is conveyed toward the supply device 30, the amount of the cereal culm increases and becomes thicker, and the conveying speed gradually decreases, so that the conveying 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 mowing unit transmission 52, the rotation transmitted to the mowing unit 4 is increased to not only facilitate the operation of the lodging grain culm, but also correspondingly, the rear conveying devices 17, 18 and There is an effect that the transfer speed of the stock-taking-over transfer device 76 can be changed to ensure the transfer.
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 grain culm supply device 30 raises the upper cover 34 of the threshing device and moves the clamping rod 33 upward to open the upper surface of the supply and transport chain 32, and then connects the transmission to the drive gear 37. Is removed and the lock of the lock device 97 for fixing the terminal end of the guide rail 35 to the machine side is released, and then the terminal end of the guide rail 35 is pivoted outward about the vertical column 38, so that the grain stalk feeding device 30 and The threshing room 31 of the threshing apparatus 3 is maintained.
