【０００１】
【発明の属する技術分野】
この発明は、機体を移動しながら、例えば圃場の稲を刈り取って脱穀処理するコンバインにおける穀粒排出装置に関する。
【０００２】
【従来の技術】
コンバインに設けた排出オ−ガを伸縮する構成のものは公知である。
【０００３】
【発明が解決しようとする課題】
然し乍ら、伸縮を操作する伸縮操作手段を運転席やタンク側にのみ設けるものが考えられているために、穀粒をトラック等の運搬車に排出する場合、排出口の位置決めに手間がかかり、あるいは不慣れな場合には穀粒を荷台外に排出することもある。
【０００４】
【課題を解決するための手段】
この発明は、このような課題を解決するコンバインにおける穀粒排出装置を提供するものであって、つぎのような技術的手段を講じた。
すなわち、走行装置（１）を具備する車台（２）に、刈取部（３）と該刈取部（３）で刈り取った穀稈を脱穀する脱穀部（４）と穀粒を貯留するタンク（５）とを設け、前記タンク（５）の底部に下部螺旋（１８）を設けると共に該タンク（５）の外壁にＬ字状のロアチューブ（１９）を設け、該ロアチューブ（１９）の縦筒部に揚穀装置（６）の揚穀筒（２０）を縦方向の軸芯まわりに回動可能に立設すると共に前記揚穀筒（２０）に設ける揚穀螺旋（２１）の螺旋軸（２２）を前記ロアチューブ（１９）の縦筒部に軸受を介して回転可能に設け、前記下部螺旋（１８）の端部をロアチューブ（１９）の横筒部に軸受を介して回転可能に設けると共に該下部螺旋（１８）の軸端部に設けた傘歯車と前記螺旋軸（２２）の軸端部に設けた傘歯車とを噛み合わせて下部螺旋（１８）からの回転動力を螺旋軸（２２）に伝動するように構成し、前記揚穀筒（２０）の上部に固定ケース（２７）を設けて該固定ケース（２７）に対して回動ケース（２８）を横軸芯回りに回動可能に設けると共に該固定ケース（２７）内および回動ケース（２８）内に前記揚穀螺旋（２１）の回転動力を排出オーガ（７）の排出螺旋へ伝動する伝動機構を設け、該排出オーガ（７）を固定筒（２３）と該固定筒（２３）の軸芯方向に移動する移動筒（２４）とから構成し、前記固定ケース（２７）または該固定ケース（２７）に一体に取り付けた取付け板（３１）側に移動螺子軸（３５）を回転自在に設けると共に該移動螺子軸（３５）を正逆転させるモータ（３６）を設ける一方、前記移動筒（２４）の基部に設けた突起（３７）を移動螺子軸（３５）の螺子部に噛み合わせて移動螺子軸（３５）が回転すると突起（３７）が移動螺子軸（３５）の螺子部を移動して移動筒（２４）を移動させる構成とし、該移動筒（２４）の先端部に前記モータ（３６）を起動操作する伸縮操作手段を設けると共に該移動筒（２４）の移動によって排出オーガ（７）が最長位置または最短位置に達したときにリミットスイッチによって前記モータ（３６）の駆動を強制的に断つように構成するにあたり、前記移動螺子軸（３５）における始端側の螺子のピッチ（Ｐ１）を該移動螺子軸（３５）における中間部の螺子のピッチ（Ｐ）よりも小さくすることによって排出オーガ（７）の最長側近くあるいは最短側近くで移動筒（２４）の移動速度を遅くして前記リミットスイッチの破損を防止することができるように構成したことを特徴とするコンバインとする。
【０００５】
運転者は運転部で機体の回転各部を駆動し、変速レバ−、操作レバ−等を操作して機体を前進させ作業を開始する。すると、刈取部３で刈り取られて後方に搬送された稲は、脱穀部４で脱穀処理され、そして、穀粒は脱穀部４からタンク５に送られ貯留される。穀粒を排出する場合には、排出オ−ガ７をトラック等の荷台に向けて移動して穀粒排出の運転を行うと、穀粒は揚穀装置６、排出オ−ガ７を介して排出される。この排出時に、排出オ−ガ７の移動筒２４の先端部に設けた伸縮操作手段を操作することにより、排出オ−ガ７を所望位置に調節できる。
【０００６】
【効果】
穀粒の排出側で排出オ−ガ７の長さを調節できるので、トラックや運搬車等の穀粒収容部への穀粒排出を効率よく行うことが出来、穀粒排出作業能率の向上を図れる。
また、排出オーガ７の最短側近くあるいは最長側近くでは移動筒２４の移動速度が遅くなるので、この移動筒２４の最短位置及び最長位置を検出するリミットスイッチの破損を防止することができる。
【０００７】
【発明の実施の形態】
以下、本発明の実施の一形態を図面に基づいて説明する。
まず、その構成について説明すると、コンバイン８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）１を具備する車台２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２の左側部に脱穀部４を設け、該脱穀部４の右側部にタンク５を設け、該タンク５と刈取部３との間の空間部にキャビン９によって囲まれ各種操作レバ−や表示具等を備えた運転部１０を設け、前記脱穀部４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）１１を設けている。
【０００８】
刈取部３は左右横方向に複数個配置した分草体１２と、後方斜め上方に移動する引き起こしラグ１３を有し横方向に複数個配置した引き起こし装置１４と、バリカン型の刈取装置１５と、刈取った穀稈を後方上方に搬送する刈取穀稈搬送装置１６とを一体に構成している。なお、刈取部３への駆動部に、例えばＨＳＴのような変速手段（有段、無段いずれでもよい）を設けている。また、引き起こし装置１４への駆動部に、例えばＨＳＴのような変速手段（有段、無段いずれでもよい）を設けることもできる。
【０００９】
脱穀部４は機体の進行方向に回転する穀稈自動送り込み装置１７を一側部に有し、前記刈取穀稈搬送装置１７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。
タンク５は下方を細く形成した中空のタンクで底部に下部螺旋１８を設けていると共に外壁にＬ状のロアチュ−ブ１９を着脱自在に設けている。そして、該ロアチュ−ブ１９の縦筒部に、縦方向への離脱を阻止するが縦方向の軸芯に対して略水平には回動可能に設けている取付け手段（図示せず）により揚穀装置６の揚穀筒２０を立設している。なお、回動手段として、実施例では、車台側に設けたモ−タ（図示せず２）により回転するギヤと揚穀筒２０の下端部に設けたギヤとを噛み合わせ、このモ−タを駆動することにより揚穀筒２０を回動する構成としている。
【００１０】
そして、揚穀筒２０に設けた揚穀螺旋２１の螺旋軸２２はロアチュ−ブ１９の縦筒部に軸受を介して回転可能に設け、前記下部螺旋１８の搬送側端部をロアチュ−ブ１９の横筒部に軸受を介して回転可能に設けていると共に、該下部螺旋１８の軸端部に設けた傘歯車（図示せず）と螺旋軸２２の軸端部に設けた傘歯車（図示せず）とを噛み合わせ、下部螺旋１８からの回転動力を螺旋軸２２に伝動する構成としている。
【００１１】
排出オ−ガ７は固定筒２３と、先端部の前面に伸縮操作手段（実施例ではスイッチであるが、レバ−等他の手段でもよい）を設けて固定筒２３の軸芯方向に移動し全体の長さを変更する移動筒２４とで構成している。接続ケ−ス２６は、下端部を前記揚穀筒２０の上部に着脱自在に設けた固定ケ−ス２７と、該固定ケ−ス２７に対して横軸芯回りに回動可能に取り付けた回動ケ−ス２８とからなり、両ケ−ス内に揚穀螺旋２１の回転動力を排出オ−ガ７の排出螺旋（図示せず）へ伝動する伝動機構（ギヤ、軸等）を設けている。２９は一端部を前記揚穀筒２０に取付け、他端部を固定筒２３に取り付けた排出オ−ガ昇降装置（実施例では油圧シリンダ、ピストン等の油圧装置である）である。
【００１２】
排出オ−ガ伸縮機構３０は一端部を固定ケ−ス２７（固定筒２３でもよい）に一体に取り付けた取付け板３１に軸受３２を介して回転自在に設け、他端部を移動筒２４に取り付けた取付け板３３に軸受３４を介して回転自在に設けた移動ネジ軸３５と、スイッチ３８の入り操作により起動し移動ネジ軸３５を正・逆転し得る正逆転モ−タ３６等で構成している。３７は移動ネジ軸３５のネジ部に噛み合う突起であって、移動筒２４の基部に設けており、移動ネジ軸３５が回転すると、突起３７がネジ部を移動して移動筒２５を移動する構成である。
【００１３】
なお、移動筒２４の移動により、排出オ−ガ７が最長又は最短になったとき、正逆転モ−タ３６の駆動を強制的に断つ構成としている。さらに、移動ネジ軸３５の移動始端側と移動終端側のネジのピッチＰ1を中間部のピッチＰよりも小さく設けている。
つぎに、その作用について説明する。
【００１４】
まず、運転者は運転部１０の座席に座り、駐車ブレ−キペダルを踏み込んでキ−をキ−スイッチに入れ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。
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−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−及び刈取レバ−を操作して脱穀部４、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。
【００１５】
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、つづいて変速レバ−を側に回動して機体を前進させると共に操作レバ−を前後方向に傾倒して刈取部３の高さ位置を決め、または左右に傾倒して機体の進行方向を変更しながら分草体１２を所定の条間に合わせる。すると、引き起こしケ−スに沿って斜め後方上方に移動する引き起こしラグ１３で引き起こされた穀稈の株元部は、刈取装置１５によって切断されて刈取穀稈搬送装置１６に受け継がれ後方上方に搬送される。
【００１６】
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１７に挟持されて後方に搬送され、排稈処理装置１１に送り込まれて処理されるが、穀稈の穂部はその途中で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タンク５に送り込まれ収容される。
【００１７】
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８を畦の近くに移動させる。そして、作業者は運転部１０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７を上昇し、起動したモ−タはギヤを介して揚穀筒２０を回動する。その後、排出オ−ガ７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。
【００１８】
この時、排出オ−ガ７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１８、揚穀螺旋２１、排出螺旋の回転により、ロアチュ−ブ１９、揚穀筒２０、接続ケ−ス２６の固定ケ−ス２７及び回動ケ−ス２８、固定筒２３、移動筒２４をその順に通って排出口から排出され荷台に収容される。
【００１９】
ところが、排出オ−ガ７の排出口がトラック等の運搬車の荷台の適正位置にないとき、あるいは荷台に偏って貯留している場合には、荷台側にいる作業者は排出オ−ガ７の先端部にあるスイッチを「入り」にする。すると、正逆転モ−タ３６は起動して正転するので、移動ネジ軸３５のネジ部と噛み合っている突起３７は固定筒２３から離れる方向に移動して排出オ−ガ７の全長を長くする。反対に、排出オ−ガ７の全長が長い場合には、スイッチを操作して正逆転モ−タ３６を逆転すると、移動ネジ軸３５も逆転するので突起３７は固定筒側に移動し排出オ−ガ７の全長を短くする。そして、排出オ−ガ７の排出口が所定位置に到達したとき、スイッチを切りにすると、正逆転モ−タ３６の駆動を停止する。
【００２０】
この突起３７が移動する時、移動ネジ軸３５の移動始端側と移動終端側のネジのピッチを中間部よりも小さく設けているので、移動筒２４が排出オ−ガ７の最短側あるいは最長側近くでは移動速度が遅くなり、最短位置及び最長位置を検出するセンサ、例えばリミットスイッチの破損を防止出来る。
さらに、作業者はトラックや運搬車等の穀粒の収容側で排出オ−ガ７を伸縮操作することができ、穀粒の排出作業能率の向上を図れる。
【００２１】
（別実施例１）
コンバイン８の側面視において、揚穀筒２０を排藁処理装置１１の後端部と略同位置になるように設けると、タンク５の前後幅を大きく形成できるので、穀粒の貯留量を増加でき収穫作業能率の向上を図れる。
（別実施例２）
排藁処理装置１１を揚穀筒２０に取付け具３８を介して回動自在に設けると、排藁処理装置１１の回動範囲を大きく取ることができるので、排藁処理装置１１や脱穀部４の点検・清掃作業が容易になる。また、揚穀筒２０に回動支点を設けることにより排藁処理装置１１の回動フレ−ムを別途設ける必要がなく構成を簡単にできる。

Furthermore, the pitch P1 of the screw at the movement start end side and the movement end side of the moving screw shaft 35 is set smaller than the pitch P at the intermediate portion.
Next, the operation will be described.
[0014]
First, when the driver sits on the seat of the driving unit 10, depresses the parking brake pedal, puts the key into the key switch and starts the engine, the power output from the engine is transmitted to the rotating parts of the aircraft through the transmission mechanism. Be transmitted.
Then, the throttle lever is rotated to select the engine at a predetermined number of revolutions, the auxiliary transmission lever is rotated to a desired position, for example, the standard is selected, and the threshing lever and the cutting lever are operated. When the threshing unit 4 and the reaping unit 3 are driven, the machine conditions and the like are displayed on each indicator on the instrument panel.
[0015]
When the preparation of the harvesting work is completed, the depression of the parking brake pedal is released, and then the shift lever is rotated to the side to advance the machine body and the operation lever is tilted back and forth to raise the height of the cutting unit 3. The position of the plant body 12 is determined or tilted to the left and right to change the traveling direction of the aircraft, and the weed body 12 is adjusted to a predetermined length. Then, the root part of the grain culm caused by the cause lug 13 that moves obliquely rearward and upward along the cause case is cut by the reaping device 15 and inherited by the reaper cereal transportation device 16 to be conveyed rearward and upward. Is done.
[0016]
Then, the culm that has reached the end of conveyance is sandwiched by the automatic culm feeding device 17 and transported backward and sent to the waste processing device 11 for processing. It is sent into the room and processed for threshing. Processed products such as grains produced by this are wind-selected and separated into grains and straw scraps, and the grains are fed into the tank 5 and accommodated by a conveying device such as the first helix and the first grain raising device. .
[0017]
Thereafter, when the grains in the tank are full, the driver interrupts the harvesting operation and moves, for example, the combine 8 near the straw. Then, when the operator operates the discharge auger turning tool of the operation unit 10, the discharge auger lifting / lowering device raises the discharge auger 7, and the activated motor moves the milling cylinder 20 through the gear. Rotate. Thereafter, when the discharge agar 7 reaches the target position, the operator stops the operation of the discharge agar turning tool.
[0018]
At this time, if the discharge port of the discharge agar 7 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 rotated by the lower helix 18, the hulling helix 21, and the discharge helix, so that the lower tube 19, the hulling cylinder 20, the fixing case 27 of the connection case 26, and the rotating case. 28, fixed cylinder 23, is accommodated in the carrier is discharged movable barrel 2 4 from the discharge port through in that order.
[0019]
However, when the discharge port of the discharge agar 7 is not at the proper position of the loading platform of a transport vehicle such as a truck, or when it is biased and stored in the loading platform, the worker on the loading platform side can discharge the discharge agar 7. the switch on the of the tip to "containing". Then, since the forward / reverse motor 36 is activated and rotates forward, the projection 37 engaged with the screw portion of the moving screw shaft 35 moves away from the fixed cylinder 23 to lengthen the entire length of the discharge agar 7. To do. Conversely, the discharge o - if the total length of the gas 7 is long, forward and reverse rotation mode by operating the switch - when reverse motor 36, the projections 37 so also moves the threaded shaft 35 is reversed to move the fixed cylinder side exhaust The total length of the auger 7 is shortened. The exhaust O - when the discharge port of the gas 7 reaches the predetermined position, when the off switch, forward and reverse mode - stops driving the motor 36.
[0020]
When the projection 37 is moved, since the provided smaller than the intermediate portion pitch of the movement starting side and the moving end side of the screw moving screw shaft 35, the movable barrel 2 4 emissions o - shortest side or longest moth 7 Near the side, the moving speed becomes slow, and the sensor for detecting the shortest position and the longest position, for example, a limit switch can be prevented from being damaged.
Furthermore, the operator can extend / contract the discharge agar 7 on the grain storage side such as a truck or a transporter, and the efficiency of the grain discharge work can be improved.

(Example 1)
In the side view of the combine 8, when the cereal cylinder 20 is provided so as to be substantially in the same position as the rear end portion of the waste disposal apparatus 11, the front and rear width of the tank 5 can be formed large, so that the amount of stored grains is increased. The harvesting work efficiency can be improved.
(Another embodiment 2)
When the waste disposal apparatus 11 is rotatably provided on the cereal barrel 20 via the attachment 38, the rotational range of the waste disposal apparatus 11 can be increased, and therefore the waste disposal apparatus 11 and the threshing unit 4 are disposed. Inspection and cleaning work becomes easier. Further, by providing a rotation fulcrum on the whipping cylinder 20, it is not necessary to separately provide a rotation frame of the waste disposal apparatus 11, and the configuration can be simplified.
