【０００６】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【０００７】
まず、その構成について説明すると、収穫機（実施例では、コンバイン）５は、機体の前進方向に向かって、左右方向に所定の間隔を置いて配置した走行装置（クロ−ラ型であるが、車輪又は車輪とクロ−ラとの組合わせによる構成としてもよい）６を具備する車台７の前部に油圧式の昇降手段によって昇降自在に刈取部３を設け、該刈取部３の後方で車台７の左側部に脱穀装置８を設け、該脱穀装置８の右側部にグレンタンク９を設け、該グレンタンク９と刈取部３との間の空間部に運転部１を設け、前記脱穀装置８の後側に排藁処理装置（実施例では排藁切断装置であるが、排藁結束装置、排藁収束装置、あるいはこれら装置の組み合わせでもよい）１０を設けている。
【０００８】
刈取部１は左右横方向に複数個配置した分草体１１と、後方斜め上方に移動する引き起こしラグを有し横方向に複数個配置した引き起こし装置１２と、バリカン型の刈取装置１３と、刈取った穀稈を後方上方に搬送する穀稈搬送装置１４とを一体に構成している。なお、刈取部１の横方向への移動手段は、公知の手段と同様で詳細な説明を省略するが、横移動駆動手段（実施例では正逆転モ−タ３４）及びこの横移動駆動手段により作動するねじ軸、ギヤ等の作動機構により行う構成である。
【０００９】
脱穀装置８は機体の進行方向に回転する穀稈自動送り込み装置１５を一側部に有し、前記刈取部３が搬送してきた穀稈の株元部を挟持後搬送して穂先部を扱室内に送り込み脱穀する自脱型の構成である。
【００１０】
走行装置６はミッションケ−ス１６から左右方向（機体の進行方向に対して横方向）に突出した駆動軸１７の両端部に着脱自在に設けた駆動スプロケット１８と、前後方向に長く形成した転輪フレ−ム１９に回動自在に前後方向に複数個設けた転輪２０と、最後の転輪よりも後方に配置した従動輪２１と、駆動スプロケット１８と転輪２０及び従動輪２１に巻き掛けた無端のクロ−ラ２２を具備している。なお、ミッションケ−ス１６には油圧を利用して左側の駆動軸１７及び右側の駆動軸１７への回転動力を伝達・停止するクラッチ２３，２４を設けている。運転部１は作業者が座る座席部２５や、右側部に機体の操向及び刈取部３の昇降を行う操作レバ−２、エンジンを起動するエンジンスイッチ２６等を有し座席部２５の前方に設けた前操作体２７や、前端部がこの前操作体２７の左端部に接続し機体の前進方向に向かって座席部２５の左横側部まで延出している横操作体２８等を設けている。操作レバ−２の握り部３３の横面には横移動スイッチ４を設けている。
【００１１】
横操作体２８は複数個設けた長溝に機体の進行速度の変速を操作する主変速レバ−２９、副変速レバ−３０、刈取部１の駆動・停止を操作する刈取レバ−３１、脱穀装置８の回転各部を駆動・停止操作する脱穀レバ−３２を設けている。
【００１２】
グレンタンク９に貯留している穀粒は揚穀筒４３と連通する排出オ−ガ４４を介して機外に排出する構成としている。
【００１３】
図６のブロック回路について説明すると、３５は必要なデ−タや制御プログラムを内蔵するメモリ３６有するマイクロコンピュ−タの演算制御部（以下「ＣＰＵ」と呼ぶ）であって、該ＣＰＵ３５に入力インタ−フェイス３７を介して入力される情報の一部としては、エンジンスイッチ２６からのエンジン入り切り情報、横移動スイッチ４からの刈取部横移動情報、操作レバ−２の回動範囲内に設け且つ左側への傾倒・解除により入り切りする左側方向変更スイッチ３８からの左側方向変更情報、操作レバ−２の回動範囲内に設け且つ右側への傾倒・解除により入り切りする右側方向変更スイッチ３９からの右側方向変更情報等がある。
【００１４】
そして、出力インタ−フェイス４０を介してＣＰＵ３５から出力する駆動指令信号として、電磁弁４１，４２への指令信号、正逆転モ−タ３４への正転又は逆転の指令信号等がある。
【００１５】
つぎに、その作用について説明する。
【００１６】
まず、運転者は運転部１の座席部２５に座り、駐車ブレ−キペダルを踏み込んでエンジンスイッチ２６を入りしてエンジンを起動すると、エンジンから出力された動力は伝動機構を介して機体の回転各部に伝動される。
【００１７】
そして、スロットルレバ−を回動してエンジンを所定回転数に選択すると共に、副変速レバ−３０を所望位置に回動して、例えば標準を選択し、さらに脱穀レバ−３２及び刈取レバ−３１を操作して脱穀装置８、刈取部３を駆動すると、機械条件等が計器パネルの各表示具に表示される。
【００１８】
収穫作業の準備を終えると、駐車ブレ−キペダルの踏み込みを解除し、つづいて主変速レバ−２９を前側に回動して機体を前進させると共に操作レバ−２を前後方向に傾倒して刈取部１の高さを決める。そして、操作レバ−２を左側に倒すと、左側方向変更スイッチ３８が入りになるので、入力インタ−フェイス３７を介して左側方向変更情報を取り込んだＣＰＵ３５は、出力インタ−フェイス４０を介して電磁弁４１のソレノイドに励磁信号を出力し電磁弁４１を作動する。これに関連して、クラッチ２３は送りこまれた油圧オイルの押圧力により伝達状態から切り状態に切り替わるので、走行装置６の左側の駆動軸２１に取り付けた駆動スプロケット１８の回転は停止し、一方右側の駆動スプロケット１８は回転状態にあって、機体を左側に変更する。
【００１９】
操作レバ−２を右側に倒すと、右側方向変更スイッチ３９が入りになるので、入力インタ−フェイス３７を介して左側方向変更情報を取り込んだＣＰＵ３５は、出力インタ−フェイス４０を介して電磁弁４２のソレノイドに励磁信号を出力し電磁弁４２を作動する。これに関連して、クラッチ２４は送りこまれた油圧オイルの押圧力により伝達状態から切り状態に切り替わるので、走行装置６の右側の駆動軸２１に取り付けた駆動スプロケット１８の回転は停止し、一方左側の駆動スプロケット１８は回転状態にあって、機体を右側に変更する。
【００２０】
このような、操作レバ−２の操作によって、分草体１１を所定の条間に合わせると、引起こし装置１２の引き起こしラグで引き起こされた穀稈の株元部は、刈取装置１３によって切断された後穀稈搬送装置１４によって後方上方に搬送される。
【００２１】
そして、搬送終端部に到達した穀稈は穀稈自動送り込み装置１５に挟持されて後方に搬送され、排稈処理装置１０に送り込まれて処理されるが、穀稈の穂部はその途中で脱穀装置８の扱室内に送り込まれて脱穀処理される。これにより生じた穀粒などの処理物は風選されて穀粒とわら屑に分離され、穀粒は一番螺旋、一番物揚穀装置等の搬送装置によってグレンタンク９に送り込まれ収容される。
【００２２】
このような収穫作業において、刈取部３を横方向に移動させた方が作業性がよくなるときがある。例えば、刈取部３を左側に移動する場合には、運転者は横移動スイッチ４を入りにすると共に操作レバ−２を左側に倒して左側方向変更スイッチ３８を入りにする。すると、ＣＰＵ３５は入力インタ−フェイス３７を介して刈取部横移動情報及び左側方向変更スイッチ情報を取り込んで、正逆転モ−タ３４を正転するので、ねじ軸、ギヤ等の作動機構は作動して刈取部３を左側に移動する。
【００２３】
反対に、刈取部３を右側に移動する場合には、運転者は横移動スイッチ４を入りにしているとき、あるいは入っている場合に、操作レバ−２を右側に倒して右側方向変更スイッチ３９を入りにする。すると、ＣＰＵ３５は入力インタ−フェイス３７を介して刈取部横移動情報及び左側方向変更スイッチ情報を取り込んで、正逆転モ−タ３４を逆転するので、ねじ軸、ギヤ等の作動機構は作動して刈取部３を右側に移動する。
【００２４】
このように、操作頻度の高い操作レバ−２を操作することにより刈取部３を左側又は右側に移動することができるので、操作ミスのない刈取部移動操作を行うことができる。そして、機体の進行方向の変更操作方向と刈取部３の移動方向の操作方向が同じであるので、刈取部３の移動操作を行い易い。さらに、機体の進行方向の変更操作と刈取部３の移動操作を同時に行うことがないので、機体の条合わせ時に機体が振れず居住性を高め得る。
【００２５】
その後、タンク内の穀粒が満杯になると、運転者は収穫作業を中断して、例えばコンバイン５を畦の近くに移動させる。そして、作業者は運転部１の排出オ−ガ旋回具を操作すると、排出オ−ガ昇降装置は排出オ−ガ４４を上昇し、起動したモ−タはギヤを介して揚穀筒４３を回動する。その後、排出オ−ガ４４が目標位置に到達すると、作業者は排出オ−ガ旋回具の操作を停止する。
【００２６】
この時、排出オ−ガ４４の排出口がトラック等の運搬車の荷台の上方に位置しておれば、排出クラッチを入りにする。すると、タンク内の穀粒は下部螺旋、揚穀螺旋、排出螺旋の回転により、ロアチュ−ブ、揚穀筒４３をその順に通って排出オ−ガ４４の排出口から排出され荷台に収容される。
【００２７】
なお、刈取部３の右カバ−４５と運転部１とが左右方向において重なったコンバイン５であり、刈取部３が刈取支持懸架４６の横軸芯を回動中心４７にして上下方向に回動する構成としている。そして、運転部１の前操作体２７は、前記刈取部３の回動軌跡と略一定の間隔（すき間）を保つように、前記右カバ−４５と前操作体２７の前カバ−４８を円弧状に形成している。これにより、刈取部３からの騒音を減音でき、刈取部内に発生するホコリの飛散を減少し、前記すき間を小さくできるので安全性も向上する。
【００２８】
図５はコンバイン５の側面から見ており、前操作体２７に、刈取部３の右カバ−４５と重なる防音カバ−４９を設けており、これにより、防塵効果を一層高め得る。

[0015]
Next, the operation will be described.
[0016]
First, when the driver sits on the seat part 25 of the driving part 1, depresses the parking brake pedal, enters the engine switch 26 and starts the engine, the power output from the engine is transmitted to the rotating parts of the aircraft via the transmission mechanism. It is transmitted to.
[0017]
Then, the throttle lever is rotated to select the engine at a predetermined number of revolutions, and the auxiliary transmission lever 30 is rotated to a desired position, for example, a standard is selected, and the threshing lever 32 and the cutting lever 31 are further selected. Is operated to drive the threshing device 8 and the mowing unit 3, the machine conditions and the like are displayed on each indicator on the instrument panel.
[0018]
When the preparation of the harvesting work is completed, the depression of the parking brake pedal is released, and then the main transmission lever 29 is rotated forward to advance the machine body and the operation lever-2 is tilted in the front-rear direction to cut the cutting part. Determine the height of 1. Then, when the operation lever-2 is tilted to the left, the left direction change switch 38 is turned on, so that the CPU 35 that has taken in the left direction change information via the input interface 37 is electromagnetically connected via the output interface 40. An excitation signal is output to the solenoid of the valve 41 to operate the solenoid valve 41. In this connection, the clutch 23 is switched from the transmission state to the disengagement state by the pressing force of the hydraulic oil sent in, so that the rotation of the drive sprocket 18 attached to the drive shaft 21 on the left side of the traveling device 6 stops, while the right side The drive sprocket 18 is in a rotating state and changes the fuselage to the left side.
[0019]
When the operation lever-2 is tilted to the right, the right direction change switch 39 is turned on, so that the CPU 35 that has fetched the left direction change information via the input interface 37 receives the electromagnetic valve 42 via the output interface 40. The solenoid valve 42 is actuated by outputting an excitation signal to the solenoid. In relation to this, the clutch 24 is switched from the transmission state to the disengagement state by the pressing force of the fed hydraulic oil, so that the rotation of the drive sprocket 18 attached to the drive shaft 21 on the right side of the traveling device 6 stops, while the left side. The drive sprocket 18 is in a rotating state and changes the airframe to the right side.
[0020]
When the weed body 11 is adjusted to the predetermined length by the operation of the operation lever-2 as described above, after the root portion of the cereal caused by the raising lag of the pulling device 12 is cut by the reaping device 13 It is conveyed rearward and upward by the cereal conveying device 14.
[0021]
Then, the cereal that has reached the end of conveyance is sandwiched by the cereal automatic feeding device 15 and conveyed rearward, and sent to the waste disposal device 10 for processing. The threshing process is performed by feeding into the handling chamber of the apparatus 8. Processed products such as the grains thus produced are wind-selected and separated into grains and straw scraps, and the grains are fed into the glen tank 9 and accommodated by a conveying device such as the first helix and the first cerealing device. The
[0022]
In such a harvesting operation, the workability may be improved by moving the cutting unit 3 in the lateral direction. For example, when the mowing unit 3 is moved to the left side, the driver turns on the lateral movement switch 4 and turns the operation lever 2 to the left side to turn on the left direction change switch 38. Then, the CPU 35 takes in the mowing part lateral movement information and the left direction change switch information via the input interface 37 and rotates the forward / reverse motor 34 in the forward direction, so that the operation mechanism such as the screw shaft and gear operates. The mowing unit 3 is moved to the left side.
[0023]
On the other hand, when the mowing unit 3 is moved to the right side, the driver turns the operation lever-2 to the right side and switches the right direction change switch 39 when the lateral movement switch 4 is turned on or when it is turned on. To enter. Then, the CPU 35 takes in the mowing unit lateral movement information and the left direction change switch information via the input interface 37 and reverses the forward / reverse motor 34, so that the operating mechanism such as the screw shaft and gear operates. The mowing unit 3 is moved to the right side.
[0024]
As described above, by operating the operation lever-2 having a high operation frequency, the reaping part 3 can be moved to the left or right side, so that the reaping part moving operation without an operation error can be performed. And since the change operation direction of the advancing direction of an airframe and the operation direction of the moving direction of the cutting part 3 are the same, the moving operation of the cutting part 3 is easy to perform. Furthermore, since the operation of changing the direction of travel of the aircraft and the operation of moving the cutting unit 3 are not performed at the same time, the aircraft does not shake during the alignment of the aircraft and the comfort can be improved.
[0025]
After that, when the grains in the tank are full, the driver interrupts the harvesting operation and moves the combine 5 near the straw, for example. Then, when the operator operates the discharge auger turning tool of the operation unit 1, the discharge agar lifting device raises the discharge agar 44, and the activated motor moves the whipping cylinder 43 through the gear. Rotate. Thereafter, when the discharge agar 44 reaches the target position, the operator stops the operation of the discharge agar turning tool.
[0026]
At this time, if the discharge port of the discharge agar 44 is positioned above the loading platform of a transport vehicle such as a truck, the discharge clutch is engaged. Then, the grains in the tank are discharged from the discharge port of the discharge auger 44 through the lower tube and the cereal tube 43 in this order by rotation of the lower spiral, the cereal spiral, and the discharge spiral, and are stored in the loading platform. .
[0027]
Note that the right cover 45 of the cutting unit 3 and the operating unit 1 are the combine 5 in which the left and right directions overlap each other, and the cutting unit 3 rotates in the vertical direction about the horizontal axis of the cutting support suspension 46 as the rotation center 47. It is configured to do. Then, the front operating body 27 of the operating unit 1 is configured so that the right cover 45 and the front cover 48 of the front operating body 27 are in a circle so as to maintain a substantially constant interval (gap) with respect to the turning locus of the cutting unit 3. It is formed in an arc shape. Thereby, the noise from the cutting part 3 can be reduced, the scattering of dust generated in the cutting part can be reduced, and the clearance can be reduced, thereby improving the safety.
[0028]
FIG. 5 is seen from the side surface of the combine 5, and the front operating body 27 is provided with a soundproof cover 49 that overlaps the right cover 45 of the cutting unit 3, thereby further enhancing the dustproof effect.
