Description

【0001】
【発明の属する技術分野】
本発明は、コンバインの刈取駆動装置に関し、農業機械の技術分野に属するものである。
【0002】
【従来の技術】
従来からコンバインの伝動装置は、エンジンから出力された回転動力が脱穀装置側と走行用の油圧無段変速装置側とに分岐して伝動される構成となっている。そして、刈取前処理装置は、上記分岐した動力が走行ミッション装置を経由して走行側に伝達される動力の一部を刈取側に分割して取り出し伝動される構成となっている。
【0003】
更に、従来からコンバインは、前部に装着している刈取前処理装置を、車体フレ−ムから着脱自由に分離したり、又は車体フレ−ムとの間に回動支点を設けて刈取前処理装置を車体フレ−ムの側部側に回動して、車体フレ−ムとの間に作業空間を作り、メンテナンスを容易に行なうことができる刈取オ−プン装置が知られている。
【0004】
【発明が解決しようとする課題】
上述したように、従来のコンバインは、走行装置と刈取前処理装置とが一連の伝動系に形成され、脱穀装置とは別の伝動系に構成されていた。したがって、刈取前処理装置の穀稈搬送装置は、脱穀装置のフィ−ドチエンとは伝動系が異なるために、始動や停止、及び搬送速度の変速等が別々に行われ、刈取穀稈を受継搬送する過程で受継作用に円滑性を欠ぎ、稈こぼれ等が発生する課題があった。
【0005】
そこで、本案は、刈取前処理装置とフィ−ドチエンとを一つの油圧無段変速装置から伝動する構成にして、上述した課題(穀稈受継時の課題)を解決すると共に、更に、伝動機構の配置とメンテナンスの容易化を図り、刈取オ−プン回動時には伝動ベルトの取外し等の手間を極力少なくして支障なく対応できる装置を提供せんとするものである。
【0006】
【課題を解決するための手段】
本発明は、上述した課題を解決するために、次の如き技術手段を講ずるものである。まず、請求項1の発明は、オイルタンク1を装備した油圧ポンプ2aと、該油圧ポンプ2aから循環される作動油によって駆動される油圧モ−タ2bとを一体に組み合わせて油圧無段変速装置2を構成し、該油圧無段変速装置2は、コンバイン3に搭載して刈取前処理装置4と脱穀装置5のフィ−ドチエン6とを伝動する構成としたコンバインの刈取駆動装置であって、刈取前処理装置側の穀稈搬送装置と脱穀装置側のフィ−ドチエンとを同一の伝動経路にして連動させ、始動、停止、変速を同時に行なわせて、穀稈搬送装置の終端部からフィ−ドチエンに搬送穀稈を受け継ぐとき極めて円滑に受継搬送ができるものとなった。
【0007】
つぎに、請求項2の発明は、油圧ポンプ2aと油圧モ−タ2bとを一体に組み合わせて構成された油圧無段変速装置2は、刈取前処理装置4の左側に寄せた位置でフィ−ドチエン6に近い側に搭載して構成した請求項1記載のコンバインの刈取駆動装置であって、油圧無段変速装置と、これに付随する入力側と出力側との伝動装置を、刈取前処理装置の左外側から比較的簡単にメンテナンスができるものとなっている。
【0008】
つぎに、請求項3の発明は、刈取前処理装置4は、縦方向の回動支点軸7にオ−プン回動自由に支持して設け、オイルタンク1を一体に設けた油圧ポンプ2aと油圧モ−タ2bとを組み合わせて構成された油圧無段変速装置2は、前記回動支点軸7に近い位置において、前記刈取前処理装置4側と一体になって刈取オ−プン回動ができる構成とした請求項1、又は請求項2記載のコンバインの刈取駆動装置であって、刈取オ−プン回動にあたり、油圧ポンプの入力側と、油圧モ−タの出力側とに巻回している伝動ベルトを取り外す必要がなく、そのまま車体の側部に回動できるものとなっている。
【0009】
そして、油圧ポンプは、実施例の場合、オイルタンクを一体に設けた構成にしているから、刈取オ−プン回動時に、送油ホ−スが邪魔(外す必要がない)にならない利点もある。
つぎに、請求項4の発明は、刈取前処理装置4とフィ−ドチエン6とを伝動する油圧無段変速装置2は、走行装置8を伝動する油圧無段変速装置9の操作装置10と連動する操作装置11により変速操作される構成とした請求項1記載のコンバインの刈取駆動装置であって、実施例の場合、一本の変速レバ−で2つの油圧無段変速装置を連動させながら変速操作ができるものとなっている。したがって、2つの油圧無段変速装置は、操作が簡略化されていて楽であるとともに、刈取前処理装置とフィ−ドチエンとが同調する上に、走行速度ともシンクロ状態が確保され、車速に応じて連動した刈取速度、搬送速度が自動的に得られるものとなっている。
【0010】
【発明の効果】
以上のように構成することによって、請求項1の発明は、刈取前処理装置の穀稈搬送装置から脱穀装置のフィ−ドチエンに至る搬送穀稈の受け継ぎがきわめて円滑にでき、受け継ぎ穀稈の乱れが防止できる特徴がある。
【0011】
そして、請求項2の発明は、刈取前処理装置とフィ−ドチエンとを伝動する油圧無段変速装置と付随する伝動装置のメンテナンスが容易にできるものとなった特徴がある。
そして、請求項3の発明は、刈取前処理装置は、油圧無段変速装置を搭載した構成でありながら、油圧ポンプの入力側と油圧モ−タの出力側との伝動ベルトを取り外す必要がなく、そのままで刈取オ−プン回動ができ、従来に比較して手間がかからない優れた特徴がある。
【0012】
そして、本案に係る油圧ポンプは、オイルタンクと一体構成のためにホ−スが露出しておらず、刈取オ−プン回動にあたり、通常なら問題となるオイルタンクとの間の送油ホ−スが邪魔(外す必要がない)にならない特徴がある。
そして、請求項4の発明は、一本の変速レバ−で2つの油圧無段変速装置を連動して変速操作ができる便利なもので、操作が簡略化された特徴がある。そして、本案は、刈取前処理装置とフィ−ドチエンとが同調する上に、走行速度と刈取速度、搬送速度がシンクロ状態を保って変速できる点でも特徴がある。
【0013】
【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具体的に説明する。
まず、コンバイン3は、図2、及び図3に示すように、左右一対の走行装置8、8を車体12の下側に装置し、その車体12には、一方(左側)に脱穀装置5を搭載し、該脱穀装置5に併設して他方(右側)にはグレンタンク13を搭載し、前側には刈取前処理装置4を連結して構成している。
【0014】
そして、走行装置8、8は、図2、及び図3に示すように、クロ−ラから構成されており、前部低位置の走行ミッション装置14から左右両外側に延長したホイルシャフト15、15の外側端部に軸着した駆動スプロケット16、16に巻回して構成している。17は転輪であって、上記クロ−ラ(走行装置8)を巻回し案内する構成としている。
【0015】
以上のように、コンバイン3は、車体12の前部に設けた刈取前処理装置4で刈取った穀稈を穀稈搬送装置18によって搬送し、脱穀装置5のフィ−ドチエン6に株元を受け継がせ、穂先部分を脱穀装置5に供給して刈取・脱穀作業ができる構成としている。
【0016】
つぎに、刈取前処理装置4と、その刈取オ−プン機構について説明する。
まず、刈取前処理装置4は、図1、乃至図3に示すように、後部を横向きの短い刈取伝動筒19に連結、固定した刈取フレ−ム20の前部に横長の刈取伝動ケ−ス21を連結し、刈取フレ−ム20に内装した伝動軸22によって刈取伝動筒19から刈取伝動ケ−ス21に回転動力を伝動する構成としている。この場合、刈取フレ−ム20は、図3で解るように、車体12前部の高い支持位置にある基部(後部)の刈取伝動筒19から前方低位置に傾斜させて設け、先端部(前部)の刈取伝動ケ−ス21が低い位置にある構成としている。そして、刈取前処理装置4は、上記刈取フレ−ム20と刈取伝動ケ−ス21とに、前部から順番に上下に傾斜した穀稈引起し装置23と、その後方の低位置に刈取装置24と、刈取穀稈を搬送する穀稈搬送装置18とを設けてそれぞれ伝動可能に構成している。なお、穀稈搬送装置18は、株元搬送チエンと穂先搬送ラグとの上下二段を一組として構成している。25は分草杆である。
【0017】
そして、伝動支持ケ−ス26は、図1、及び図6に示すように、縦回動部26aと横回動支持部26b(右側)と油圧無段変速装置2の支持部26c(左側)とから形成し、正面視でT型にして一体に形成し、円筒形状の筒素材によって構成している。そして、上記伝動支持ケ−ス26は、図面から解るように、縦回動部26aを車体12の前部に設けた縦方向の回転支点軸7に回転自由に嵌合して全体を支持して設け、横回動支持部26bには前記刈取伝動筒19を横側から挿入して回転自由に支持して構成している。そして、刈取上下油圧シリンダ27は、一方(シリンダ側)を上記縦回動部26aの取付部28に取付け、他方(ピストン側)を前記刈取フレ−ム20の取付部29に取付けて設け、刈取前処理装置4を上下調節する構成としている。
【0018】
以上のように、正面視T型の伝動支持ケ−ス26は、縦回動部26aが車体12の回転支点軸7を回動支点にして左右方向に回転して刈取オ−プン回動を可能とし、横回動支持部26bの外周に嵌合して支持した刈取伝動筒19を横軸回りに回転させて刈取上下回動(刈高方向の調節)を可能にした構成としている。そして、前記刈取上下油圧シリンダ27は、縦回動部26a(取付部28)、及び刈取フレ−ム20(取付部29)と一体に刈取オ−プン回動するから、回動途中のどの位置においても刈取前処理装置4を上下調節することができる特徴のある構成となっている。
【0019】
そして、前記刈取伝動筒19は、図1に示し、既に説明したように、前進方向左側が横回動支持部26bにより回動自由に軸受支持されているが、その反対側に回動軸30を右方向に突出して形成し、車体12に載置状態にして伝動支持ケ−ス26と共に刈取オ−プン回動ができる軸受装置31に支持した構成としている。
【0020】
そして、前述した油圧無段変速装置2は、図1に示すように、伝動支持ケ−ス26の支持部26cに取付けて支持されているが、上部にオイルタンク1を一体に取付けた油圧ポンプ2aと、該油圧ポンプ2aから循環される作動油によって駆動される油圧モ−タ2bとを一体に組み合わせて構成している。そして、油圧無段変速装置2は、油圧ポンプ2aがエンジン32側に接続した入力ベルト33から回転動力が入力され、油圧モ−タ2bが刈取側出力軸34とフィ−ドチエン6への出力ベルト35とを設けて変速後の回転動力を両方に出力する構成としている。
【0021】
このように、油圧無段変速装置2は、コンバイン3に搭載して刈取前処理装置4と脱穀装置5のフィ−ドチエン6との両方を伝動する構成であって、図1に示すように、刈取前処理装置4の左側に寄せた位置でフィ−ドチエン6に近い側に配置した構成となっている。そして、この実施例の場合、油圧ポンプ2aと油圧モ−タ2bとを組み合わせて構成した油圧無段変速装置2は、前記回動支点軸7に近い位置において支持部26cに連結・支持しており、前記刈取前処理装置4と一体(回転支点軸7の回りに回動する点において)にした構成であって、刈取オ−プン回動ができる構成となっている。
【0022】
そして、油圧無段変速装置2は、図1に示すように、走行ミッション装置14側に搭載して回転動力をその走行ミッション装置14に入力する油圧無段変速装置9の操作装置10と連動する操作装置11により変速操作される構成としている。すなわち、操作装置10と操作装置11とは、図面に示すように、一つの変速レバ−36に操作連杆37を介して連結し、一操作で両方の油圧無段変速装置2、9を連動させて操作ができる構成としている。
【0023】
このように、二つの油圧無段変速装置2、9は、図5の両者の変速関連性を示すグラフのように、一つの変速レバ−36から操作連杆37を介して連動されて変速操作され、車速に対してシンクロした状態で刈取前処理装置4(刈取、搬送)と脱穀装置5のフィ−ドチエン6とを変速しながら伝動する構成にしている。そして、油圧無段変速装置2は、グラフから解るように、車速が0のとき(油圧無段変速装置9がニュ−トラル位置のとき)でも、必ず一定の回転速度を保持して駆動状態にある構成にしている。
【0024】
そして、上記一定の回転速度(初期速度)は、図6に示すように、初期速度設定ダイヤル38を設けて基準設定値に対して増速、又は減速に速度を選定して設定できる構成としている。実施例では、初期速度設定ダイヤル38は、図示しないコントロ−ラに接続して設定値が入力されると、コントロ−ラから、図6の初期速度設定モ−タ39に制御信号を出力して駆動し、油圧無段変速装置2の変速位置を調整、設定することができる構成としている。
【0025】
そして、初期速度は、図5のグラフに示すように、圃場条件(作業条件)に合わせて選択するが、倒伏穀稈が多い圃場では基準設定値に比較して高速設定値にすれば、初期速度が増速され引起しラグが高速で回転して効果的な引起し作用ができ、逆に、脱粒しやすい品種では低速設定値にして作業を始めると脱粒が減り、稲の品種に合った作業ができる特徴がある。
【0026】
なお、図5のグラフは、横軸に車速を取り、縦軸に刈取前処理装置(フィ−ドチエン6も含む)の速度を取って表示した。
以上述べたように、刈取前処理装置4は、刈取フレ−ム20の基部が刈取伝動筒19に固定され、その刈取伝動筒19が伝動支持ケ−ス26に支持されているから、縦回動部26aを左右に回して刈取オ−プン回動ができ、横回動支持部26bを支点にして刈取伝動筒19を回動して刈取上下調節ができるものであって、支持構成がコンパクトになった利点がある。
【0027】
そして、上述の伝動支持ケ−ス26は、図4に示すように、縦回動部26aの中間部に設けたオ−プン従動ギヤ40に、オ−プン用モ−タ41のオ−プン駆動ギヤ42を噛合して刈取オ−プン回動を自動で行なう構成としている。この場合、オ−プン用モ−タ41は、コンバイン3の操縦座席43に配置しているパワステレバ−44に設けた操作スイッチ45(左回転、右回転)によって操作できる構成にしている。
【0028】
このように構成すると、パワステレバ−44は、一本の操作レバ−によって、一番目の機能として左右に倒せば走行装置8、8の舵取り(操向)操作ができ、二番目の機能として前後に操作すれば刈取前処理装置4の昇降操作ができる構成であって、その上に加えて上述の操作スイッチ45により、三番目の機能として刈取オ−プン回動操作ができるものとなって、コンバインの操作系をまとめることで操作が容易になった特徴がある。
【0029】
以上説明したように、本案の実施例は、油圧無段変速装置2によって刈取前処理装置4とフィ−ドチエン6とを一連の下に伝動するから、搬送穀稈の受け継ぎ作用に乱れがなく、きわめて円滑に受継いで整然とした搬送ができるものとなっている。特に、穀稈搬送装置18とフィ−ドチエン6とは、始動、停止、変速等が同時に行われ、一連の搬送装置になっているから、受け継ぎ時において搬送乱れや稈こぼれが発生することはない。
【0030】
そして、実施例の場合、油圧無段変速装置2を脱穀装置5に近いずけて刈取前処理装置4の後部左側に配置しているから、脱穀装置5の左側から入力伝動機構が設けられ、伝動が取り易い上にこれらのメンテナンスが容易にできる利点もある。
【0031】
そして、刈取前処理装置4は、実施例の場合、回動支点軸7に近い位置に油圧無段変速装置2を搭載して刈取オ−プン回動ができる構成にしているから、油圧ポンプ2aの入力側と油圧モ−タ2bの出力側とのベルト33、35を取り外す必要がなく、そのままで刈取オ−プン回動ができ、従来に比較して手間がかからない優れたものとなっている。
【0032】
そして、本案実施例の油圧ポンプ2aは、刈取オ−プン回動にあたり、通常なら問題となるオイルタンク1との間の送油ホ−スがないために、何らの心配もなく刈り取オ−プン操作ができるものとなっている。
そして、本案実施例の場合、操作系を統一して一本の変速レバ−36で2つの油圧無段変速装置2、9を連動して変速操作ができる便利なもので、操作が簡略化された特徴がある。そして、本案は、刈取前処理装置4とフィ−ドチエン6とを一つの伝動系にして、走行装置8、8とは別の伝動系にしたものでありながら、走行速度と刈取速度、搬送速度がシンクロ状態を保って変速できるものである特徴もある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a combine harvester drive device and belongs to the technical field of agricultural machinery.
[0002]
[Prior art]
BACKGROUND ART Conventionally, a combine transmission has a configuration in which rotational power output from an engine is branched and transmitted to a threshing device and a traveling hydraulic continuously variable transmission. The mowing pre-processing device is configured so that the branched power is transmitted by dividing a part of the power transmitted to the traveling side via the traveling mission device to the mowing side.
[0003]
Further, conventionally, the combine harvester has a pre-cutting processing device mounted on a front portion thereof, which is detachable from a vehicle body frame, or a turning fulcrum is provided between the device and the vehicle body frame. 2. Description of the Related Art There is known a mowing open device in which a device is pivoted to a side portion of a vehicle body frame to create a working space between the device and the vehicle body frame and maintenance can be easily performed.
[0004]
[Problems to be solved by the invention]
As described above, in the conventional combine, the traveling device and the pre-cutting device are formed in a series of transmission systems, and are configured in a transmission system different from the threshing device. Therefore, since the transmission system of the grain culm transport device of the pre-cutting device is different from that of the feed chain of the threshing device, starting and stopping, shifting of the transport speed, and the like are performed separately, and the harvested grain culm is inherited and transported. During the process, there is a problem in that the inherited action lacks smoothness, and culm spills and the like occur.
[0005]
Therefore, the present invention solves the above-described problem (the problem at the time of inheriting the grain stalk) by transmitting the pre-cutting device and the feed chain from one hydraulic continuously variable transmission, and furthermore, furthermore, the transmission mechanism An object of the present invention is to provide a device which facilitates arrangement and maintenance, and which can cope with the trouble by minimizing trouble such as removal of a power transmission belt when a mowing open is rotated.
[0006]
[Means for Solving the Problems]
The present invention takes the following technical means in order to solve the above-mentioned problems. First, a first aspect of the present invention is a hydraulic continuously variable transmission that integrally combines a hydraulic pump 2a equipped with an oil tank 1 and a hydraulic motor 2b driven by hydraulic oil circulated from the hydraulic pump 2a. 2, the hydraulic continuously variable transmission 2 is a combine harvester drive device mounted on the combine 3 and configured to transmit the pre-cutting device 4 and the feed chain 6 of the threshing device 5; The stalk transport device on the pre-cutting device side and the feed chain on the threshing device side are linked to each other on the same power transmission path to simultaneously start, stop, and shift, and feed from the end portion of the culm transport device to the feeder. When the transported grain culm was transferred to Dochien, it became possible to carry out the transport very smoothly.
[0007]
Next, according to a second aspect of the present invention, the hydraulic continuously variable transmission 2, which is formed by integrally combining the hydraulic pump 2a and the hydraulic motor 2b, 2. The harvesting drive for a combine according to claim 1, wherein said drive is mounted on the side close to the dochien 6, and comprises a hydraulic stepless transmission and an associated input-side and output-side transmission. Maintenance can be performed relatively easily from the left outside of the device.
[0008]
Next, according to a third aspect of the present invention, the pre-cutting device 4 is provided so as to be freely rotatably supported on a vertical rotation fulcrum shaft 7 and has a hydraulic pump 2a integrally provided with an oil tank 1. The hydraulic continuously variable transmission 2 configured by combining the hydraulic motor 2b with the cutting pre-processing device 4 at a position near the rotation fulcrum shaft 7 allows the cutting open rotation to be performed. 3. A harvesting drive for a combine according to claim 1 or 2, wherein the harvester is wound around an input side of a hydraulic pump and an output side of a hydraulic motor upon rotation of the harvesting open. There is no need to remove the power transmission belt, and it can be turned to the side of the vehicle body as it is.
[0009]
In the case of the embodiment, the hydraulic pump has a structure in which the oil tank is provided integrally. Therefore, there is an advantage that the oil supply hose does not become obstructive (there is no need to remove it) when the cutting open is rotated. .
Next, according to a fourth aspect of the present invention, the hydraulic continuously variable transmission 2 that transmits the pre-cutting device 4 and the feed chain 6 is interlocked with the operating device 10 of the hydraulic continuously variable transmission 9 that transmits the traveling device 8. 2. A combine harvesting drive device according to claim 1, wherein the speed change operation is carried out by an operating device (11) that performs two-speed stepless transmission by interlocking two hydraulic continuously variable transmissions with one transmission lever. It can be operated. Therefore, the two hydraulic continuously variable transmissions are simplified and easy to operate, and the cutting pre-processing device and the feed chain are synchronized with each other, and the running speed is synchronized with the vehicle speed, and the speed is synchronized with the vehicle speed. The interlocked harvesting speed and transport speed are automatically obtained.
[0010]
【The invention's effect】
With the above-described configuration, the invention of claim 1 can extremely smoothly transfer the grain culm from the grain culm conveying device of the pre-cutting device to the feed chain of the threshing device, and disturb the inherited grain culm. There is a feature that can be prevented.
[0011]
The invention of claim 2 is characterized in that maintenance of the hydraulic continuously variable transmission that transmits the pre-cutting device and the feed chain and the associated transmission can be easily performed.
According to a third aspect of the present invention, there is no need to remove the transmission belt between the input side of the hydraulic pump and the output side of the hydraulic motor, even though the mowing pre-processing device has a configuration in which the hydraulic continuously variable transmission is mounted. The cutting open rotation can be performed as it is, and there is an excellent feature that requires less labor than the conventional one.
[0012]
In the hydraulic pump according to the present invention, the hose is not exposed because the hose is integrated with the oil tank, and the oil supply hose between the oil tank, which is normally a problem in turning the cutting open, is required. There is a feature that does not get in the way (no need to remove).
Further, the invention of claim 4 is a convenient one in which two hydraulic continuously variable transmissions can be operated in conjunction with one another by a single transmission lever, and the operation is simplified. The present invention is characterized in that the pre-cutting device and the feed chain synchronize with each other, and that the running speed, the cutting speed, and the transport speed can be changed while maintaining a synchronized state.
[0013]

The pre-processing device 4 is configured to be adjusted up and down.
[0018]
As described above, in the T-type transmission support case 26 as viewed from the front, the vertical rotation portion 26a rotates left and right around the rotation fulcrum shaft 7 of the vehicle body 12 as a rotation fulcrum, thereby rotating the reaper open. The mowing transmission tube 19 fitted and supported on the outer periphery of the lateral rotation supporting portion 26b is rotated around a horizontal axis to enable vertical rotation of the mowing (adjustment in the height direction). Since the cutting vertical hydraulic cylinder 27 is rotated integrally with the vertical rotating portion 26a (the mounting portion 28) and the cutting frame 20 (the mounting portion 29), the cutting upper and lower hydraulic cylinders 27 are in any position during the rotation. Also has a characteristic configuration in which the pre-cutting device 4 can be adjusted up and down.
[0019]
As shown in FIG. 1 and described above, the cutting transmission cylinder 19 is rotatably supported on the left side in the forward direction by the lateral rotation supporting portion 26b. Are formed so as to protrude rightward, are mounted on the vehicle body 12, and are supported by a bearing device 31 which can rotate the harvesting open together with the transmission support case 26.
[0020]
As shown in FIG. 1, the above-described hydraulic continuously variable transmission 2 is mounted on and supported by a support portion 26c of a transmission support case 26, but a hydraulic pump having an oil tank 1 integrally mounted on an upper portion thereof. 2a and a hydraulic motor 2b driven by hydraulic oil circulated from the hydraulic pump 2a. The hydraulic continuously variable transmission 2 receives rotational power from an input belt 33 to which the hydraulic pump 2 a is connected to the engine 32, and the hydraulic motor 2 b outputs an output belt to the cutting output shaft 34 and the feed chain 6. 35 is provided to output the rotational power after shifting to both.
[0021]
As described above, the hydraulic continuously variable transmission 2 is mounted on the combine 3 and transmits both the pre-cutting device 4 and the feed chain 6 of the threshing device 5, as shown in FIG. The arrangement is such that it is arranged on the side close to the feed chain 6 at a position close to the left side of the pre-cutting device 4. In this embodiment, the hydraulic continuously variable transmission 2 composed of a combination of the hydraulic pump 2a and the hydraulic motor 2b is connected to and supported by the supporting portion 26c at a position close to the rotation fulcrum shaft 7. In addition, it is integrated with the cutting pre-processing device 4 (at the point of rotation about the rotation fulcrum shaft 7), and is configured to be able to rotate the cutting open.
[0022]
As shown in FIG. 1, the hydraulic continuously variable transmission 2 is mounted on the traveling transmission device 14 and is interlocked with the operating device 10 of the hydraulic continuously variable transmission 9 that inputs rotational power to the traveling transmission device 14. The shift operation is performed by the operation device 11. That is, as shown in the drawing, the operating device 10 and the operating device 11 are connected to one shift lever 36 via the operating connecting rod 37, and the two hydraulic continuously variable transmissions 2 and 9 are linked by one operation. It is configured so that it can be operated.
[0023]
In this way, the two hydraulic continuously variable transmissions 2 and 9 are operated by one gear lever 36 via the operation connecting rod 37 in conjunction with the gear shifting operation, as shown in the graph of FIG. In this state, the pre-cutting device 4 (cutting and transporting) and the feed chain 6 of the threshing device 5 are transmitted while changing the speed in synchronization with the vehicle speed. As can be seen from the graph, even when the vehicle speed is 0 (when the hydraulic continuously variable transmission 9 is in the neutral position), the hydraulic continuously variable transmission 2 always maintains a constant rotational speed and enters the driving state. I have a certain configuration.
[0024]
As shown in FIG. 6, the constant rotation speed (initial speed) is provided with an initial speed setting dial 38 so that the speed can be set to be increased or reduced with respect to a reference set value. . In this embodiment, when the initial speed setting dial 38 is connected to a controller (not shown) and a set value is input, the controller outputs a control signal to the initial speed setting motor 39 in FIG. 6 from the controller. When driven, the shift position of the hydraulic continuously variable transmission 2 can be adjusted and set.
[0025]
Then, as shown in the graph of FIG. 5, the initial speed is selected according to the field conditions (working conditions). The speed is increased and the lag is rotated at high speed to produce an effective raising action. Conversely, for varieties that are easy to shatter, setting the low speed to a low value and starting work reduces shattering and is suitable for rice varieties. There is a feature that can work.
[0026]
In the graph of FIG. 5, the horizontal axis indicates the vehicle speed, and the vertical axis indicates the speed of the pre-cutting device (including the feed chain 6).
As described above, in the pre-cutting device 4, the base of the cutting frame 20 is fixed to the cutting transmission tube 19, and the cutting transmission tube 19 is supported by the transmission support case 26. The mowing opening can be rotated by rotating the moving portion 26a left and right, and the mowing transmission tube 19 can be rotated with the laterally rotating support portion 26b as a fulcrum so that the mowing can be adjusted up and down. There are advantages.
[0027]
As shown in FIG. 4, the above-mentioned transmission support case 26 is connected to an open driven gear 40 provided at an intermediate portion of the vertical rotating portion 26a by an open motor 41 of an open motor. The drive gear 42 is engaged to automatically rotate the cutting open. In this case, the open motor 41 is configured to be operated by an operation switch 45 (left rotation, right rotation) provided on a power steering wheel 44 arranged on the control seat 43 of the combine 3.
[0028]
With such a configuration, the power telescope 44 can be steered (steered) by operating the traveling devices 8 and 8 as a first function by tilting the power device 44 left and right with a single operation lever. When operated, the mowing pre-processing device 4 can be moved up and down. In addition to the above, the operating switch 45 allows the mowing opener to be operated as a third function. There is a feature that the operation has been facilitated by putting together the operation systems.
[0029]
As described above, in the embodiment of the present invention, the pre-cutting device 4 and the feed chain 6 are transmitted by the hydraulic continuously variable transmission 2 in a series of downward directions. It is very smooth inheritance and can be transported in an orderly manner. In particular, since the cereal culm conveying device 18 and the feed chain 6 are started, stopped, shifted, and the like at the same time and are a series of conveying devices, there is no occurrence of turbulence or spilling of the culm at the time of inheritance. .
[0030]
In the case of the embodiment, since the hydraulic continuously variable transmission 2 is arranged close to the threshing device 5 and disposed on the rear left side of the pre-cutting device 4, an input transmission mechanism is provided from the left side of the threshing device 5, There is an advantage that the transmission can be easily taken and the maintenance can be easily performed.
[0031]
