Is done. Therefore, the cutting input shaft 17 can be operated via the cutting drive shaft 102 at a constant rotational speed from the high-speed constant rotating gear 110 that is faster than the maximum speed of the vehicle speed tuning output, and the harvesting workability of the fallen cedar can be improved. . It is to be noted that the cutting input shaft 17 is actuated by a rotational force equal to or less than the torque set by the torque limiter 104 to prevent the cutting blade 32 and the like from being damaged.
カウンタギヤケース99には、選別入力軸82にフィードチェン駆動軸103を連結する遊星ギヤ形変速構造のフィードチェン同調機構112が設けられている。選別入力軸82の回転出力が、フィードチェン同調機構112によって刈取伝動軸101の回転数に比例して変速されて、フィードチェン駆動軸103に伝達される。即ち、フィードチェン同調機構112を介してフィードチェン6を作動することによって、穀稈の搬送に必要な最低回転数(低速側一定回転ギヤ109からの一定回転数)を確保し乍ら、フィードチェン6の穀稈搬送速度を車速と同調させて変更可能に構成している。   The counter gear case 99 is provided with a feed chain tuning mechanism 112 having a planetary gear type transmission structure that connects the feed chain drive shaft 103 to the selection input shaft 82. The rotation output of the sorting input shaft 82 is shifted in proportion to the rotational speed of the cutting transmission shaft 101 by the feed chain tuning mechanism 112 and transmitted to the feed chain drive shaft 103. That is, by operating the feed chain 6 via the feed chain tuning mechanism 112, the feed chain is secured while ensuring the minimum rotational speed (constant rotational speed from the low-speed constant rotational gear 109) necessary for conveying the cereal. The cereal conveyance speed of 6 can be changed in synchronization with the vehicle speed.
次に、本実施形態の穀稈搬送手段としての縦搬送チェン34の搬送速度制御について説明する。図8は、縦搬送チェン34の搬送速度制御手段の機能ブロック図であり、制御プログラムを記憶したROMと各種データを記憶したRAMとを有するマイクロコンピュータ等の作業コントローラ282を備えている。図8に示されるように、マイクロコンピュータで構成する作業コントローラ282の入力側には、作業クラッチレバー44の脱穀クラッチ78入り操作及び切り操作(脱穀装置5の駆動等)を検出する作業スイッチ273と、穀稈引起装置223の穀稈(未刈り穀稈)又は穀稈搬送装置224の穀稈(刈取穀稈)を検出する穀稈センサ287と、走行機体1の移動速度を検出する車速センサ285と、刈取駆動軸102の回転数を検出する刈取り回転センサ288と、縦搬送チェン34の穀稈搬送上流側の右搬送駆動軸62の回転数を検出する上流側搬送速度センサ291と、縦搬送チェン34の穀稈搬送下流側の後搬送駆動軸54の回転数を検出する下流側搬送速度センサ292と、作業クラッチレバー44によるテンションクラッチ115(刈取クラッチ)の入り操作及び切り操作を検出する刈取クラッチセンサ293と、縦搬送駆動用電動モータ92の出力回転数(縦搬送チェン34の作動速度)を無段階に調節する搬送速度設定ダイヤル262と、縦搬送駆動用電動モータ92の最低出力回転数(縦搬送チェン34の最低作動速度)を設定する最低回転数設定器としての低速回転設定器266と、縦搬送駆動用電動モータ92の最高出力回転数(縦搬送チェン34の最高作動速度)を設定する最高回転数設定器としての高速回転設定器267と、縦搬送駆動用電動モータ92の出力回転数を検出する縦搬送回転センサ312とを接続している。   Next, the conveyance speed control of the vertical conveyance chain 34 as the cereal conveyance means of this embodiment will be described. FIG. 8 is a functional block diagram of the conveyance speed control means of the vertical conveyance chain 34, and includes a work controller 282 such as a microcomputer having a ROM storing a control program and a RAM storing various data. As shown in FIG. 8, on the input side of the work controller 282 constituted by a microcomputer, a work switch 273 that detects the operation of turning on and off the threshing clutch 78 of the work clutch lever 44 (driving of the threshing device 5 and the like) , A culm sensor 287 that detects the culm (uncut cereal) of the culm pulling device 223 or the culm (harvested cereal) of the cereal conveyance device 224, and a vehicle speed sensor 285 that detects the moving speed of the traveling machine body 1. A cutting rotation sensor 288 that detects the rotation speed of the cutting drive shaft 102, an upstream conveyance speed sensor 291 that detects the rotation speed of the right conveyance drive shaft 62 on the upstream side of the cereal conveyance of the vertical conveyance chain 34, and vertical conveyance The downstream clutch speed sensor 292 that detects the number of rotations of the rear conveyance drive shaft 54 on the downstream side of the grain haul conveyance of the chain 34, and the tension clutch 11 by the work clutch lever 44. (Cutting clutch) A cutting clutch sensor 293 that detects a turning operation and a cutting operation, and a conveyance speed setting dial 262 that adjusts the output rotation speed (operating speed of the vertical conveyance chain 34) of the vertical conveyance driving electric motor 92 steplessly. A low-speed rotation setting device 266 as a minimum rotation number setting device for setting a minimum output rotation number of the vertical conveyance drive electric motor 92 (minimum operating speed of the vertical conveyance chain 34), and a maximum of the vertical conveyance drive electric motor 92. A high-speed rotation setting device 267 as a maximum rotation number setting device for setting the output rotation number (maximum operating speed of the vertical conveyance chain 34), a vertical conveyance rotation sensor 312 for detecting the output rotation number of the electric motor 92 for vertical conveyance driving, and Is connected.
図8に示す如く、作業コントローラ282の出力側には、縦搬送駆動用電動モータ92を作動する縦搬送ドライバ302を接続している。エンジン14によって駆動する発電機89に、縦搬送駆動用電動モータ92及び縦搬送ドライバ302を接続させ、発電機89を電源として、縦搬送駆動用電動モータ92を作動可能に構成している。その結果、車速センサ285の検出結果と、速度変更ダイヤルとしての搬送速度設定ダイヤル262の設定値とに基づき、縦搬送駆動用電動モータ92を自動的に増速又は減速制御できるから、刈取り穀稈の性状等に関係なく、刈取り穀稈の穂先側が株元よりも若干先行した脱穀姿勢になるように刈取り穀稈を搬送でき、例えば脱穀装置5において扱き残し又は稈切れ等が発生するのを防止でき、且つ刈取り穀稈の搬送姿勢の乱れ等を低減でき、穀稈搬送手段としての縦搬送チェン34やフィードチェン6等の穀稈搬送性能を向上できる。   As shown in FIG. 8, a vertical conveyance driver 302 that operates the vertical conveyance driving electric motor 92 is connected to the output side of the work controller 282. An electric motor 92 for vertical conveyance driving and a vertical conveyance driver 302 are connected to a generator 89 driven by the engine 14, and the electric motor 92 for vertical conveyance driving is configured to be operable by using the generator 89 as a power source. As a result, based on the detection result of the vehicle speed sensor 285 and the set value of the conveyance speed setting dial 262 as a speed change dial, the vertical conveyance driving electric motor 92 can be automatically controlled to increase or decrease, so that Regardless of the nature, etc., the harvested cereal can be transported so that the tip side of the harvested cereal is in a threshing position slightly ahead of the stock, and for example, it is prevented from being left unhandled or broken in the threshing device 5 In addition, it is possible to reduce disturbances in the conveying posture of the harvested culm, and to improve the cereal conveying performance of the vertical conveying chain 34, the feed chain 6 and the like as the cereal conveying means.
即ち、車速センサ285が検出する移動速度(車速)と同調して変化する刈取装置3の車速同調速度を検出する刈取り回転センサ288の検出結果と、搬送速度設定ダイヤル262の設定値とに基づき、縦搬送駆動用電動モータ92の出力回転数が自動制御される。その縦搬送駆動用電動モータ92の出力回転数を自動制御中、オペレータが搬送速度設定ダイヤル262を手動回転操作し、縦搬送駆動用電動モータ92の出力回転数の自動制御に優先して、縦搬送駆動用電動モータ92の出力回転数を変更して、縦搬送チェン34の搬送速度を調整可能に構成している。その結果、搬送速度設定ダイヤル262の手動操作によって縦搬送チェン34の搬送速度を変更できるから、オペレータが搬送中の穀稈姿勢を目視しながら、搬送速度設定ダイヤル262を操作でき、穀稈の搬送姿勢の変化に追従して縦搬送チェン34の搬送速度を俊敏に変更でき、穀稈の搬送姿勢を簡単に修正できる。   That is, based on the detection result of the cutting rotation sensor 288 that detects the vehicle speed synchronization speed of the cutting device 3 that changes in synchronization with the moving speed (vehicle speed) detected by the vehicle speed sensor 285 and the set value of the transport speed setting dial 262, The output rotation speed of the vertical transfer driving electric motor 92 is automatically controlled. During the automatic control of the output rotational speed of the vertical transport driving electric motor 92, the operator manually operates the transport speed setting dial 262 to give priority to the automatic control of the output rotational speed of the vertical transport driving electric motor 92. The output speed of the transport drive electric motor 92 is changed so that the transport speed of the vertical transport chain 34 can be adjusted. As a result, since the conveyance speed of the vertical conveyance chain 34 can be changed by manual operation of the conveyance speed setting dial 262, the operator can operate the conveyance speed setting dial 262 while visually checking the posture of the culm during conveyance, thereby conveying the cereal. Following the change in posture, the conveying speed of the vertical conveying chain 34 can be quickly changed, and the conveying posture of the cereal can be easily corrected.
また、縦搬送駆動用電動モータ92の出力回転数の自動制御は、搬送速度設定ダイヤル262の手動回転操作によって設定された縦搬送速度設定値を作業コントローラ282が自動的に記憶して、低速回転設定器266によって設定された最低回転数と、高速回転設定器267によって設定された最高回転数との間で、前記縦搬送速度設定値と、刈取り回転センサ288の検出結果とに基づき、縦搬送駆動用電動モータ92の出力回転数が変更されるように構成している。即ち、搬送速度設定ダイヤル262の手動操作によって設定された縦搬送チェン34の搬送速度の手動設定値を記憶する手段としての作業コントローラ282を備え、車速センサ285の検出結果に基づき自動的に増速又は減速される縦搬送チェン34の搬送速度の変化率を、縦搬送チェン34の搬送速度の手動設定値によって変更できるから、穀稈の性状等に適応した搬送速度を維持できるものでありながら、走行機体1の移動速度と同調させて縦搬送チェン34の搬送速度を変化させることができ、縦搬送チェン34を車速同調速度で作動させたときに発生する穀稈の搬送姿勢の乱れ等を簡単に低減でき、縦搬送チェン34やフィードチェン6等の穀稈搬送性能を向上できる。   In addition, the automatic control of the output rotation speed of the vertical transfer driving electric motor 92 is performed by the work controller 282 automatically storing the vertical transfer speed setting value set by the manual rotation operation of the transfer speed setting dial 262, so that the rotation speed is low. Between the minimum number of rotations set by the setting device 266 and the maximum number of rotations set by the high-speed rotation setting device 267, based on the vertical conveyance speed setting value and the detection result of the cutting rotation sensor 288, the vertical conveyance The output rotational speed of the drive electric motor 92 is changed. That is, a work controller 282 is provided as means for storing a manual setting value of the conveying speed of the vertical conveying chain 34 set by manual operation of the conveying speed setting dial 262, and the speed is automatically increased based on the detection result of the vehicle speed sensor 285. Alternatively, since the rate of change of the transport speed of the vertical transport chain 34 to be decelerated can be changed by the manual setting value of the transport speed of the vertical transport chain 34, while maintaining the transport speed adapted to the properties of the cereal, etc. It is possible to change the transport speed of the vertical transport chain 34 in synchronization with the moving speed of the traveling machine body 1, and to easily disrupt the cereal transport posture disorder that occurs when the vertical transport chain 34 is operated at the vehicle speed synchronized speed. It is possible to reduce the cereal conveyance performance of the vertical conveyance chain 34, the feed chain 6 and the like.
なお、一定回転数で常に駆動して脱穀・選別性能を維持する必要がある脱穀装置5を備えた構造、換言すると、エンジン14からの一定回転数の出力が脱穀装置5に伝達される伝動構造において、最高出力状態で略一定回転数を維持するようにエンジン14が運転されるから、そのエンジン14からの出力によって発電機89を最適な回転数で駆動できる。即ち、縦搬送駆動用電動モータ92の作動に必要な発電機89の適正出力が確実に維持されることによって、穀稈の刈取り搬送作業に適した一定回転数で縦搬送駆動用電動モータ92を作動できる。   In addition, the structure provided with the threshing device 5 which needs to be always driven at a constant rotational speed to maintain the threshing / sorting performance, in other words, the transmission structure in which the output of the constant rotational speed from the engine 14 is transmitted to the threshing device 5. Therefore, since the engine 14 is operated so as to maintain a substantially constant rotational speed at the maximum output state, the generator 89 can be driven at an optimal rotational speed by the output from the engine 14. That is, by ensuring that the appropriate output of the generator 89 required for the operation of the vertical conveyance drive electric motor 92 is reliably maintained, the vertical conveyance drive electric motor 92 is driven at a constant rotation speed suitable for the harvesting and conveying operation of cereals. Can operate.
次に、図8は搬送速度制御のフローチャートである。図8を参照して、縦搬送駆動用電動モータ92を作動する刈取穀稈の搬送作業を説明する。オペレータが作業クラッチレバー44を刈取クラッチ切り位置から入り位置に操作して、作業クラッチレバー44のテンションクラッチ115(刈取クラッチ)入り操作が刈取クラッチセンサ293によって検出されたときに(S1yes)、車速センサ285の検出値と、刈取り回転センサ288の検出値と、上流側搬送速度センサ291の検出値と、下流側搬送速度センサ292の検出値と、搬送速度設定ダイヤル262の設定値とが読み込まれる(S2)。車速センサ285の検出値と、刈取り回転センサ288の検出値と、下流側搬送速度センサ292の検出値と、搬送速度設定ダイヤル262の設定値とから縦搬送チェン34の搬送速度(車速同調速度)が演算される(S3)。   Next, FIG. 8 is a flowchart of the conveyance speed control. With reference to FIG. 8, the conveying operation | work of the harvested grain mash which operates the electric motor 92 for a vertical conveyance drive is demonstrated. When the operator operates the work clutch lever 44 from the cutting clutch disengaged position to the entering position and the operation of the tension clutch 115 (cutting clutch) of the working clutch lever 44 is detected by the cutting clutch sensor 293 (S1yes), the vehicle speed sensor The detected value of 285, the detected value of the cutting rotation sensor 288, the detected value of the upstream transport speed sensor 291, the detected value of the downstream transport speed sensor 292, and the set value of the transport speed setting dial 262 are read ( S2). From the detection value of the vehicle speed sensor 285, the detection value of the cutting rotation sensor 288, the detection value of the downstream transfer speed sensor 292, and the set value of the transfer speed setting dial 262, the transfer speed of the vertical transfer chain 34 (vehicle speed synchronization speed). Is calculated (S3).
テンションクラッチ115(刈取クラッチ)が入り操作されてから、縦搬送チェン34の搬送速度が走行機体1の移動速度に適応した車速同調速度に増速されるまでの間、換言すると、刈取り回転センサ288の検出値と下流側搬送速度センサ292の検出値とが略一致するまでの間は、刈取り回転センサ288の検出値と下流側搬送速度センサ292の検出値とに基づき、縦搬送チェン34よりも穀稈搬送下流側の補助株元搬送チェン35,36(補助搬送手段)等の搬送速度以下に、縦搬送チェン34の搬送速度が維持される。即ち、縦搬送回転センサ312の検出値を読み込み(S4)、車速センサ285の検出値と搬送速度設定ダイヤル262の設定値とに基づき演算された縦搬送チェン34の搬送速度と、縦搬送回転センサ312の検出値(実際の搬送速度)とを比較して(S5)、縦搬送チェン34よりも穀稈搬送下流側の搬送速度以下の範囲内で、縦搬送駆動用電動モータ92の回転数(縦搬送チェン34の搬送速度)を増速制御する(S6)。したがって、縦搬送チェン34よりも穀稈搬送下流側の搬送速度以下に、縦搬送チェン34の搬送速度を維持しながら、搬送駆動用電動モータ92を増速制御して、穀稈の搬送を開始できるから、縦搬送チェン34よりも穀稈搬送下流側の穀稈受継部等で、穀稈の搬送姿勢が乱れたり、穀稈が詰まるのを簡単に防止できる。   In other words, until the conveying speed of the vertical conveying chain 34 is increased to the vehicle speed synchronization speed adapted to the moving speed of the traveling machine 1 after the tension clutch 115 (cutting clutch) is operated, in other words, the cutting rotation sensor 288. Until the detection value of the downstream conveyance speed sensor 292 substantially matches the detection value of the downstream conveyance speed sensor 292 based on the detection value of the cutting rotation sensor 288 and the detection value of the downstream conveyance speed sensor 292 than the vertical conveyance chain 34. The conveyance speed of the vertical conveyance chain 34 is maintained below the conveyance speed of the auxiliary stock source conveyance chains 35 and 36 (auxiliary conveyance means) on the downstream side of the cereal cereal conveyance. That is, the detection value of the vertical conveyance rotation sensor 312 is read (S4), the conveyance speed of the vertical conveyance chain 34 calculated based on the detection value of the vehicle speed sensor 285 and the setting value of the conveyance speed setting dial 262, and the vertical conveyance rotation sensor. The detected value (actual conveyance speed) of 312 is compared (S5), and the rotation speed of the electric motor 92 for vertical conveyance drive (within the range below the conveyance speed downstream of the vertical conveyance chain 34) ( The speed of the vertical transport chain 34 is controlled to increase (S6). Therefore, while maintaining the conveying speed of the vertical conveying chain 34 below the conveying speed downstream of the vertical conveying chain 34, the conveyance driving electric motor 92 is controlled to be accelerated to start conveying the cereal. Therefore, it is possible to easily prevent the cereal conveying posture from being disturbed or clogged with cereals at the downstream side of the culm transporter than the vertical transport chain 34.
走行機体1の移動速度に適応した車速同調速度にまで、縦搬送チェン34の搬送速度が増速されたとき、即ち、刈取り回転センサ288の検出値と下流側搬送速度センサ292の検出値とが略一致したときには、縦搬送回転センサ312の検出値を読み込み(S4)、ステップ3で演算された縦搬送チェン34の搬送速度と、縦搬送回転センサ312の検出値(実際の搬送速度)とを比較して、縦搬送チェン34の搬送速度を増速作動すべきか(S5)、縦搬送チェン34の搬送速度を減速作動すべきか(S10)を判断する。縦搬送チェン34の搬送速度を増速作動すべきと判断されたときに(S5yes)、縦搬送チェン34の搬送速度を増速作動する増速制御が実行される(S6)。その結果、走行機体1の移動速度に比例して縦搬送チェン34の搬送速度が加速され、車速と同調した速度で縦搬送チェン34を作動でき、走行機体1の移動速度に比べて縦搬送チェン34の搬送速度が遅くなりすぎることがなく、縦搬送チェン34によって搬送される穀稈の姿勢が、株元側が遅れて穂先側が先行することがなく、搬送途中での穀稈の詰り又は搬送中の穀稈の搬送姿勢の乱れ等を防止でき、縦搬送チェン34及び補助搬送チェン35,36等の搬送性能を向上できる。なお、オペレータが搬送速度設定ダイヤル262を手動操作して、縦搬送駆動用電動モータ92の回転数を任意に変更できる。例えば圃場に倒伏している穀稈の刈取り作業等の特別な条件下の刈取り作業であっても、それに適応した速度で縦搬送チェン34を作動できる。   When the conveying speed of the vertical conveying chain 34 is increased to the vehicle speed synchronization speed adapted to the moving speed of the traveling machine body 1, that is, the detected value of the cutting rotation sensor 288 and the detected value of the downstream conveying speed sensor 292 are When the values substantially coincide, the detection value of the vertical conveyance rotation sensor 312 is read (S4), and the conveyance speed of the vertical conveyance chain 34 calculated in Step 3 and the detection value (actual conveyance speed) of the vertical conveyance rotation sensor 312 are obtained. In comparison, it is determined whether the transport speed of the vertical transport chain 34 should be increased (S5) or the transport speed of the vertical transport chain 34 should be decreased (S10). When it is determined that the transport speed of the vertical transport chain 34 should be increased (S5yes), speed increase control for increasing the transport speed of the vertical transport chain 34 is executed (S6). As a result, the conveyance speed of the vertical conveyance chain 34 is accelerated in proportion to the movement speed of the traveling machine body 1, and the vertical conveyance chain 34 can be operated at a speed synchronized with the vehicle speed. 34 is not too slow, the posture of the cereals conveyed by the vertical conveying chain 34 is delayed on the stock side and the tip side is not preceded, and the cereals are clogged or being conveyed during the conveyance. It is possible to prevent the cereals from being disturbed in the conveying posture and improve the conveying performance of the vertical conveying chain 34 and the auxiliary conveying chains 35 and 36. The operator can manually change the conveyance speed setting dial 262 to arbitrarily change the number of rotations of the vertical conveyance drive electric motor 92. For example, even in a cutting operation under special conditions such as a cutting operation of cereals lying on the field, the vertical conveyance chain 34 can be operated at a speed adapted to the cutting operation.
上述の増速制御(S6)によって縦搬送チェン34の搬送速度が増速された場合、高速回転設定器267の縦搬送チェン34の最高作動速度設定値を読み込む(S7)。縦搬送チェン34の搬送速度が高速回転設定器267の最高作動速度設定値と一致して、縦搬送チェン34が高速作動していると判断されたときに(S8yes)、縦搬送チェン34の一定回転制御が実行される(S9)。走行機体1の移動速度(車速)がさらに増速されても、縦搬送チェン34の一定回転制御(S9)によって、高速回転設定器267の設定値に縦搬送チェン34の搬送速度が維持される。即ち、高速回転設定器267によって設定された回転数以下の速度で縦搬送チェン34を作動するように構成したものであるから、走行機体1の移動速度(車速)が極めて高速のときにも、縦搬送チェン34の搬送速度が速くなりすぎることがなく、縦搬送チェン34(縦搬送駆動用電動モータ92)が過負荷の状態で作動するのを防止でき、穀稈の搬送姿勢の乱れ又は縦搬送チェン34の損傷等を低減できる。   When the conveyance speed of the vertical conveyance chain 34 is increased by the speed increase control (S6) described above, the maximum operating speed setting value of the vertical conveyance chain 34 of the high-speed rotation setting device 267 is read (S7). When the conveyance speed of the vertical conveyance chain 34 matches the maximum operating speed setting value of the high-speed rotation setting device 267 and it is determined that the vertical conveyance chain 34 is operating at high speed (S8yes), the vertical conveyance chain 34 is kept constant. The rotation control is executed (S9). Even if the moving speed (vehicle speed) of the traveling machine body 1 is further increased, the conveyance speed of the vertical conveyance chain 34 is maintained at the set value of the high-speed rotation setting device 267 by the constant rotation control (S9) of the vertical conveyance chain 34. . That is, since the vertical conveyance chain 34 is configured to operate at a speed equal to or lower than the rotational speed set by the high-speed rotation setting device 267, even when the moving speed (vehicle speed) of the traveling machine body 1 is extremely high, The conveying speed of the vertical conveying chain 34 does not become too fast, and it is possible to prevent the vertical conveying chain 34 (vertical conveying driving electric motor 92) from operating in an overloaded state. Damage to the transport chain 34 can be reduced.
一方、圃場に植立した穀稈を刈取る刈取作業中、走行機体1の移動速度が減速されることによって、刈取り回転センサ288によって検出される刈取り入力軸17の回転数が減少する。換言すると、縦搬送回転センサ312によって検出される縦搬送駆動用電動モータ92の出力回転数が刈取り入力軸17の回転数よりも高くなり、縦搬送チェン34によって搬送される穀稈の株元側が先行してその穂先側が遅れた搬送姿勢になる。その場合、縦搬送駆動用電動モータ92を減速作動させる必要があると判断される。   On the other hand, during the harvesting operation for harvesting the cereals planted in the field, the rotational speed of the harvesting input shaft 17 detected by the harvesting rotation sensor 288 is reduced by reducing the moving speed of the traveling machine body 1. In other words, the output rotational speed of the vertical transport driving electric motor 92 detected by the vertical transport rotation sensor 312 is higher than the rotational speed of the cutting input shaft 17, and the stockholder side of the cereals transported by the vertical transport chain 34 is Prior to that, the tip side is delayed. In this case, it is determined that the vertical conveyance driving electric motor 92 needs to be decelerated.
即ち、刈取り入力軸17の回転数と縦搬送駆動用電動モータ92の出力回転数とを比較して、縦搬送駆動用電動モータ92を減速作動させる必要があると判断されたときに(S10yes)、縦搬送ドライバ302を減速制御して縦搬送チェン34の搬送速度を減速作動する減速制御が実行される(S11)。その結果、その減速制御(S11)によって走行機体1の移動速度(車速)に比例して縦搬送チェン34の搬送速度が減速され、車速と同調した速度で縦搬送チェン34を作動でき、走行機体1の移動速度に比べて縦搬送チェン34の搬送速度が速くなりすぎることがなく、縦搬送チェン34によって搬送される穀稈の姿勢が、株元側が先行して穂先側が遅れることがなく、搬送途中での穀稈の詰り又は搬送中の穀稈の搬送姿勢の乱れ等を防止でき、縦搬送チェン34及び補助搬送チェン35,36等の搬送性能を向上できる。   That is, when it is determined that it is necessary to decelerate the vertical conveyance drive electric motor 92 by comparing the rotation speed of the cutting input shaft 17 with the output rotation number of the vertical conveyance drive electric motor 92 (S10yes). Then, deceleration control for decelerating the conveying speed of the vertical conveying chain 34 by decelerating the vertical conveying driver 302 is executed (S11). As a result, the decelerating control (S11) decelerates the conveying speed of the vertical conveying chain 34 in proportion to the moving speed (vehicle speed) of the traveling machine body 1, and can operate the vertical conveying chain 34 at a speed synchronized with the vehicle speed. The transport speed of the vertical transport chain 34 does not become too fast compared to the movement speed of 1, and the posture of the cereals transported by the vertical transport chain 34 is not delayed by the head side and the tip side is delayed. It is possible to prevent clogging of grain halves on the way or disturbance of the conveyance posture of corn straw during conveyance, and the conveyance performance of the vertical conveyance chain 34 and auxiliary conveyance chains 35 and 36 can be improved.
上述の減速制御(S11)によって縦搬送チェン34の搬送速度が減速された場合、低速回転設定器266の縦搬送チェン34の最低作動速度設定値を読み込む(S12)。縦搬送チェン34が低速作動して、縦搬送チェン34の搬送速度が低速回転設定器266の最低作動速度設定値と一致して、縦搬送チェン34が低速作動していると判断されたときに(S13yes)、縦搬送チェン34の一定回転制御(S9)が実行される。したがって、走行機体1の移動速度(車速)がさらに減速されても、縦搬送チェン34の一定回転制御(S9)によって、低速回転設定器266の設定値に縦搬送チェン34の搬送速度が維持される。即ち、最低回転数設定器266によって設定された回転数以上の速度で縦搬送チェン34を作動できるから、走行機体1の移動速度(車速)等が極めて微速のときにも、縦搬送チェン34の搬送速度が遅くなりすぎることがなく、搬送途中の穀稈が詰るのを防止でき、縦搬送チェン34及び補助搬送チェン35,36等の搬送性能を維持できる。   When the conveyance speed of the vertical conveyance chain 34 is decelerated by the above-described deceleration control (S11), the minimum operating speed setting value of the vertical conveyance chain 34 of the low-speed rotation setting device 266 is read (S12). When it is determined that the vertical transport chain 34 is operating at a low speed because the vertical transport chain 34 operates at a low speed, the transport speed of the vertical transport chain 34 matches the minimum operating speed setting value of the low speed rotation setting device 266 (S13yes), constant rotation control (S9) of the vertical conveyance chain 34 is executed. Therefore, even if the moving speed (vehicle speed) of the traveling machine body 1 is further reduced, the conveyance speed of the vertical conveyance chain 34 is maintained at the set value of the low-speed rotation setting device 266 by the constant rotation control (S9) of the vertical conveyance chain 34. The That is, since the vertical conveyance chain 34 can be operated at a speed equal to or higher than the rotational speed set by the minimum rotational speed setting unit 266, even when the traveling speed (vehicle speed) of the traveling machine body 1 is extremely slow, The conveyance speed does not become too slow, the cereals during conveyance can be prevented from being clogged, and the conveyance performance of the vertical conveyance chain 34 and the auxiliary conveyance chains 35 and 36 can be maintained.
上述したように、縦搬送チェン34を作動する縦搬送駆動用電動モータ92と、刈刃装置222等への入力回転数を検出する刈取り回転センサ288と、縦搬送駆動用電動モータ92の回転数を変更可能な搬送速度設定ダイヤル262とを備え、刈取り回転センサ288の検出結果に基づき縦搬送駆動用電動モータ92の回転数を制御中、オペレータが搬送速度設定ダイヤル262を手動操作し、縦搬送駆動用電動モータ92の出力回転数を変更して縦搬送チェン34の搬送速度を調整可能に構成したものであるから、圃場に植立した穀稈の性状等に適応した速度で縦搬送チェン34を作動でき、縦搬送チェン34の搬送性能を向上できる。例えば、圃場に倒伏している穀稈の刈取り作業等の特別な条件下の刈取り作業であっても、倒伏している穀稈の刈取り作業に適した速度に縦搬送チェン34の搬送速度を調整できる。また、例えばフィードチェン6によって穀稈の株元を挟持搬送して脱穀装置5に供給するコンバインにおいて、穀稈の穂先側が遅れて搬送されるのを防止できるから、脱穀装置5の所要動力又は脱穀損失等を低減できる。   As described above, the vertical conveyance drive electric motor 92 that operates the vertical conveyance chain 34, the cutting rotation sensor 288 that detects the input rotation speed to the cutting blade device 222, and the rotation speed of the vertical conveyance drive electric motor 92. And a conveyance speed setting dial 262 capable of changing the speed, and the operator manually operates the conveyance speed setting dial 262 while controlling the number of rotations of the electric motor 92 for vertical conveyance drive based on the detection result of the cutting rotation sensor 288. Since the output rotation speed of the driving electric motor 92 is changed to adjust the conveying speed of the vertical conveying chain 34, the vertical conveying chain 34 is adjusted at a speed suitable for the characteristics of the cereal planted in the field. And the conveyance performance of the vertical conveyance chain 34 can be improved. For example, even if the harvesting work is performed under special conditions such as the harvesting operation of the grain straw lying on the field, the transport speed of the vertical transport chain 34 is adjusted to a speed suitable for the harvesting work of the lying grain straw. it can. Further, for example, in a combine that sandwiches and conveys the cereal stock by the feed chain 6 and supplies it to the threshing device 5, it is possible to prevent the cereal head side from being delayed and conveyed, so the required power of the threshing device 5 or threshing Loss etc. can be reduced.
例えば、圃場に植立した穀稈を刈取る刈取作業中、走行機体1の移動速度が加速されることによって、刈取り回転センサ288によって検出される刈取駆動軸102の回転数が増大しても、縦搬送回転センサ312によって検出される縦搬送駆動用電動モータ92の出力回転数が、刈取り入力軸17の回転数よりも相対的に低くならないから、縦搬送チェン34によって搬送される穀稈の株元側が遅れてその穂先側が先行した搬送姿勢になるのを防止できる。逆に、走行機体1の移動速度が減速されることによって、縦搬送駆動用電動モータ92の出力回転数が、刈取り入力軸17の回転数よりも相対的に高くなっても、縦搬送チェン34によって搬送される穀稈の株元側が先行してその穂先側が遅れる搬送姿勢になるのを防止できる。   For example, even if the rotational speed of the cutting drive shaft 102 detected by the cutting rotation sensor 288 increases by accelerating the moving speed of the traveling machine body 1 during the cutting operation of cutting the grain culm planted in the field, Since the output rotational speed of the vertical transport driving electric motor 92 detected by the vertical transport rotation sensor 312 is not relatively lower than the rotational speed of the cutting input shaft 17, the strain of cereals transported by the vertical transport chain 34 It is possible to prevent the original side from being delayed and the tip side to be in a preceding transport posture. On the contrary, even if the output rotational speed of the vertical transport driving electric motor 92 is relatively higher than the rotational speed of the cutting input shaft 17 due to the reduction in the moving speed of the traveling machine body 1, the vertical transport chain 34. It is possible to prevent the stock posture side of the cereal bowl transported by the head from leading and the tip side from being delayed.
また、縦搬送駆動用電動モータ92の最低回転数を設定する最低回転数設定器としての低速回転設定器266と、縦搬送駆動用電動モータ92の最高回転数を設定する最高回転数設定器としての高速回転設定器267とを備え、低速回転設定器266によって設定された最低回転数と、高速回転設定器267によって設定された最高回転数との間で、縦搬送駆動用電動モータ92の出力回転数を変更可能に構成したものであるから、走行機体1の移動速度(車速)等が極めて微速のときにも、縦搬送チェン34の搬送速度が遅くなりすぎることがなく、搬送途中で穀稈が詰るのを防止できる。また、走行機体1の移動速度(車速)が極めて高速のときにも、縦搬送チェン34の搬送速度が速くなりすぎることがなく、搬送中の穀稈の搬送姿勢が乱れるのを防止できる。   Further, as a low speed rotation setting device 266 as a minimum rotation number setting device for setting the minimum rotation number of the electric motor 92 for vertical conveyance driving, and as a maximum rotation number setting device for setting the maximum rotation number of the electric motor 92 for vertical conveyance driving. The high-speed rotation setting device 267 is provided, and the output of the electric motor 92 for vertical conveyance drive between the minimum rotation number set by the low-speed rotation setting device 266 and the maximum rotation number set by the high-speed rotation setting device 267. Since the rotational speed can be changed, even when the traveling speed (vehicle speed) of the traveling machine body 1 is extremely low, the transport speed of the vertical transport chain 34 is not too slow, and the Can prevent clogging. Further, even when the traveling speed (vehicle speed) of the traveling machine body 1 is extremely high, the transport speed of the vertical transport chain 34 does not become too fast, and it is possible to prevent the transport posture of the cereals being transported from being disturbed.
一方、縦搬送チェン34を作動する縦搬送駆動用電動モータ92と、前記穀稈の刈り終いを検出する刈り終いセンサとしての穀稈センサ287とを備え、前記穀稈の刈り終いが穀稈センサ287によって検出されたときに、縦搬送チェン34を高速で作動させるように構成でき、その場合、縦搬送チェン34によって搬送する穀稈量が少なくなる刈り終いのときに、縦搬送チェン34の高速作動によって、縦搬送チェン34の穀稈搬送作用を適正に維持でき、縦搬送チェン34の搬送終端側(穀稈受継部)等で稈こぼれ又は稈詰りが発生するのを防止でき、縦搬送チェン34の搬送性能を向上できる。   On the other hand, an electric motor 92 for vertical conveyance driving that operates the vertical conveyance chain 34 and a culm sensor 287 as a cutting end sensor that detects the end of reaping of the cereals are provided. When detected by the culm sensor 287, the vertical conveying chain 34 can be configured to operate at a high speed. In this case, when the amount of culm conveyed by the vertical conveying chain 34 is reduced, the vertical conveying chain 34 Due to the high-speed operation of the chain 34, the grain conveying action of the vertical conveying chain 34 can be properly maintained, and spillage or clogging can be prevented from occurring on the conveying terminal side (the grain transferring part) of the vertical conveying chain 34, etc. The transport performance of the vertical transport chain 34 can be improved.
次いで、図8を参照して、縦搬送駆動用電動モータ92を停止する刈取穀稈の搬送停止動作を説明する。オペレータが作業クラッチレバー44を刈取クラッチ入り位置から切り位置に操作して、作業クラッチレバー44のテンションクラッチ115(刈取クラッチ)切り操作が刈取クラッチセンサ293によって検出されたときに(S14yes)、上流側搬送速度センサ291の検出値が読み込まれる(S15)。テンションクラッチ115(刈取クラッチ)が切り操作されてから、縦搬送チェン34の搬送速度が略零になるまでの間は、上流側搬送速度センサ291の検出値と、縦搬送回転センサ312の検出値(実際の搬送速度)とに基づき、縦搬送チェン34よりも穀稈搬送上流側の右株元搬送チェン33R等の搬送速度以上に、縦搬送チェン34の搬送速度が維持される。   Next, with reference to FIG. 8, the conveyance stop operation of the harvested cereal culm that stops the vertical conveyance drive electric motor 92 will be described. When the operator operates the working clutch lever 44 from the cutting clutch engaged position to the cutting position and the tension clutch 115 (cutting clutch) cutting operation of the working clutch lever 44 is detected by the cutting clutch sensor 293 (S14yes), the upstream side The detection value of the conveyance speed sensor 291 is read (S15). From the time when the tension clutch 115 (cutting clutch) is operated to the time when the conveying speed of the vertical conveying chain 34 becomes substantially zero, the detected value of the upstream conveying speed sensor 291 and the detected value of the vertical conveying rotation sensor 312. Based on (actual transport speed), the transport speed of the vertical transport chain 34 is maintained at a speed higher than the transport speed of the right stock former transport chain 33R and the like on the upstream side of the grain transporter 34 relative to the vertical transport chain 34.
即ち、縦搬送チェン34よりも穀稈搬送上流側の搬送速度以上の範囲内で、縦搬送駆動用電動モータ92の回転数(縦搬送チェン34の搬送速度)が減速制御される(S16)。換言すると、上流側搬送速度センサ291の検出値と、縦搬送回転センサ312の検出値(実際の搬送速度)とを比較して、穀稈搬送上流側の搬送速度以上に縦搬送チェン34の搬送速度が維持された状態で、縦搬送駆動用電動モータ92が減速制御されて(S16)、縦搬送チェン34が搬送停止制御される(S17)。したがって、縦搬送チェン34よりも穀稈搬送上流側の搬送速度以上に、縦搬送チェン34の搬送速度を維持しながら、搬送駆動用電動モータ92を減速制御して、縦搬送チェン34を停止できる。その結果、縦搬送チェン34の穀稈搬送上流側の穀稈受継部等で、穀稈の搬送姿勢が乱れたり、穀稈が詰まるのを簡単に防止できる。   That is, the number of rotations of the vertical conveyance drive electric motor 92 (conveyance speed of the vertical conveyance chain 34) is controlled to be reduced within a range equal to or higher than the conveyance speed on the upstream side of the vertical straw chain 34 (S16). In other words, the detection value of the upstream conveyance speed sensor 291 and the detection value (actual conveyance speed) of the vertical conveyance rotation sensor 312 are compared, and the conveyance of the vertical conveyance chain 34 exceeds the conveyance speed on the upstream side of the cereal conveyance. In a state where the speed is maintained, the vertical conveyance driving electric motor 92 is controlled to decelerate (S16), and the vertical conveyance chain 34 is controlled to stop conveyance (S17). Accordingly, the vertical drive chain 34 can be stopped by decelerating the transfer drive electric motor 92 while maintaining the transfer speed of the vertical transfer chain 34 higher than the transfer speed on the upstream side of the vertical straw chain 34 than the vertical transfer chain 34. . As a result, it is possible to easily prevent the cereal conveying posture from being disturbed or clogged with cereals at the upstream side of the culm transporting part of the vertical conveying chain 34.
