ステアリングノ、ンドル及びそれを具備する作業車両  Steering wheel, handle and work vehicle equipped with the steering wheel
技術分野  Technical field
[0001] 本発明は、作業車両の機体の進路を操向操作するステアリングノヽンドル及びそれ を具備する作業車両の技術に関する。  TECHNICAL FIELD [0001] The present invention relates to a steering wheel handle that steers a course of a vehicle body of a work vehicle and a technology of a work vehicle including the steering handle.
背景技術  Background art
[0002] 従来、作業車両の操向操作を行うハンドル構造として、円環状に形成したグリップ 部からなるステアリングノヽンドルが設けられたものがあり、オペレータは特別、作業車 両を意識することなぐ一般乗用自動車のハンドルを握るのと同じ感覚にて作業車両 の機体を旋回操作することが可能である。  Conventionally, as a handle structure for steering a work vehicle, there has been provided a steering handle consisting of a grip portion formed in an annular shape, and the operator is not particularly aware of the work vehicle in general. It is possible to turn the body of the work vehicle with the same feeling as holding the steering wheel of a passenger car.
[0003] ここで、コンバイン等に代表される作業車両では、一般の乗用自動車等と異なり、シ ート部に着座して機体を走行させながら、前方下部の刈取部を目視し、圃場の穀稈 の未刈部や刈取収穫物の流れを確認する等の作業が必要となるが、前記ステアリン グの前方部が視線の妨げとなり、オペレータは操縦姿勢を大きく崩して「前のめり」の 状態、または、立ち上がった状態となって作業を行う必要があった。  [0003] Here, in a work vehicle represented by a combine or the like, unlike a general passenger car or the like, while sitting on a seat and running the aircraft, the lower cutting part is visually observed, and the grain of the field It is necessary to check the flow of uncut parts and harvested crops, but the front part of the steering hinders the line of sight, and the operator greatly collapses the steering posture, It was necessary to get up and work.
[0004] また、前記作業車両では、機体全体をよりコンパクトにするために、運転席を設ける 空間を、とかく省スペースに納める構造となっている。そのため、限られた空間内にス テアリングノヽンドルや、運転席等が配置されることとなり、オペレータが運転席に着座 した状態において、大腿部の上方にステアリングノヽンドルの後部が位置するように配 備されている。その結果、オペレータにとっては、運転席に着座する際には、ステアリ ングの横側方や、斜後方に一旦起立し、その後、体を捻りながらシート部に潜り込む 等の動作が必要となり、運転席への搭乗作業等に煩わしさがあった。  [0004] In addition, the work vehicle has a structure in which a space for installing a driver's seat can be stored in a space-saving manner in order to make the entire body more compact. For this reason, a steering wheel, a driver's seat, etc. are arranged in a limited space so that the rear part of the steering wheel is positioned above the thigh when the operator is seated in the driver's seat. It is in place. As a result, when the operator is seated in the driver's seat, it is necessary to stand up to the side of the steering or to the back of the steering, and then move into the seat while twisting the body. There was troublesome boarding work.
[0005] このような状況を改善するべぐ「特許文献 1」に記載されるステアリングノヽンドルの 構造が公知となっている。  [0005] The structure of the steering handle described in “Patent Document 1” for improving such a situation is known.
特許文献 1:特開 2000— 308409号公報  Patent Document 1: Japanese Patent Laid-Open No. 2000-308409
[0006] 前記「特許文献 1」によれば、水平方向左右に延出される横ハンドル杆と、該横ハン ドル杆の両端部において前方に向力つて内側に円弧を描きながら延出されるグリツ プ部と、によりステアリングノヽンドルを構成することで、機体前方下部の視認性を確保 することができ、オペレータは「前のめり」になることも無ぐ自然な操縦姿勢を保ちつ つ前方下部の刈取部を目視することができる。また、ステアリングノ、ンドル後部の形 状を大きく除去した形状となるため、オペレータがシートに着座した状態でも大腿部 の上方は開放され、上述した煩わしさもなぐ運転席への搭乗作業を容易に行うこと ができる。 [0006] According to the above-mentioned "Patent Document 1," a horizontal handle rod that extends horizontally in the left and right directions, and a grip that extends while drawing an arc on the inside by urging forward at both ends of the horizontal handle rod. By configuring the steering handle with the head part, visibility of the lower part of the front of the fuselage can be ensured, and the operator can cut the lower part of the front part while maintaining a natural maneuvering posture that does not cause a `` front turning ''. The part can be visually observed. In addition, since the shape of the rear part of the steering wheel and the handlebar is greatly removed, the upper part of the thigh is opened even when the operator is seated on the seat, and the boarding operation in the driver's seat without the above-mentioned troublesomeness is facilitated. It can be carried out.
[0007] し力しながら、前記ステアリングノヽンドルにおいては、グリップ部を左右個別に設け ることにより、旋回操作時に勢い余って握り締めた手が前方に滑り抜けたり、また、従 来の円環状に形成されるステアリングノヽンドルと比べて、グリップ範囲、すなわち、手 で実際に握り締めることが可能な範囲が狭くなるため、ステアリングノヽンドルの旋回操 作において、咄嗟に握った手を持ち替えようとしても、うまく握れない場合があった。 また、コンバインの全長のコンパクトィ匕により、ステアリングハンドルやフロントカバー により、分草板が見え難くなる場合がある。  [0007] However, in the steering handle, the grip part is provided separately on the left and right sides, so that the hand that is excessively squeezed during the turning operation slips forward, or in a conventional annular shape. Compared to the steering wheel that is formed, the grip range, that is, the range that can actually be tightened by hand, is narrowed. There was a case where I could not grasp it well. Also, due to the compact length of the combine, the weeding board may be difficult to see due to the steering handle and front cover.

[0020] 本発明のステアリングハンドルにおいては、作業車両に回動自在に配設され、該作 業車両の操向を操作するステアリングノヽンドルにぉ ヽて、該ステアリングノヽンドルは 作業車前方側が開口した略半円弧形状であり、該ステアリングノヽンドルの右端部を 左端部に比べて前方に延出して成形することにより、オペレータが運転席に着座した 状態で、前方下部の十分な視認性を確保することができ、また、該ステアリングハンド ルの右端部を左端部に比べて前方に延出して成形することにより、作業車両の略中 央部、すなわち、運転席に対して前方下部左側の視認性が取り分け向上し、刈取作 業時の位置合わせを容易に行うことができる。  [0020] In the steering handle of the present invention, the steering handle is disposed on the work vehicle so as to be rotatable, and the steering handle is opened on the front side of the work vehicle, with respect to the steering handle for operating the steering of the work vehicle. This is a semicircular arc shape, and the right end of the steering wheel extends forward and forms compared to the left end, ensuring sufficient visibility of the lower part of the front when the operator is seated in the driver's seat. In addition, the right end portion of the steering handle extends forward compared to the left end portion, and is formed so as to visually recognize the substantially middle portion of the work vehicle, that is, the front lower left side with respect to the driver's seat. Therefore, the position can be easily adjusted when cutting.
[0021] 本発明のステアリングハンドルにおいては、前記ステアリングノヽンドルの前方両端 部において、左右に膨らむ張り出し部をそれぞれ設けて形成することにより、操縦時 にオペレータの手が滑り抜けることもない。すなわち、ステアリングノヽンドルを旋回す るには一方の端部を前方に引き出し、他端部を後方へと引き込むが、この際、勢い 余って片側の手が前方へ滑り抜けようとしても、前記張り出し部がストッパーとなって 滑り抜けることはない。  [0021] In the steering handle according to the present invention, by forming the protruding portions bulging right and left at the front both ends of the steering handle, the operator's hand does not slip through during steering. That is, in order to turn the steering handle, one end is pulled forward and the other end is pulled backward. At this time, even if the hand on one side tends to slip forward, The part becomes a stopper and does not slip through.
また、前記張り出し部の上端部に窪みを配置することにより、オペレータはステアリ ングノヽンドルを握る際には、該窪みに親指を添えて、強固に前記ステアリングノヽンド ノレを握ることができる。  In addition, by arranging a recess at the upper end of the overhanging portion, an operator can attach a thumb to the recess and firmly hold the steering node knob when gripping the steering handle.
[0022] 本発明のステアリングハンドルにおいては、前記ステアリングノヽンドルの張り出し部 手前において、下面から内側側面に向かって、前後方向に並べた複数の膨らみを配 置することにより、オペレータは該膨らみの間隙部を案内として適切な位置にてステ ァリングノヽンドルを握ることができ、適切な操縦姿勢が保てるため、作業車両の旋回 操作時の操作性が向上する。  [0022] In the steering handle according to the present invention, by arranging a plurality of bulges arranged in the front-rear direction from the lower surface toward the inner side surface in front of the protruding portion of the steering handle, the operator can remove the gap between the bulges.

Further, a side wall portion 17 formed in a substantially “<” shape in plan view is provided on the side portion and the front portion, and a side panel, a display panel, a grip, and the like are assembled to the side wall portion.
[0038] 前記側壁部 17は、運転席 12側に向力つて下がる傾斜面が形成され、運転席 12に 着座したオペレータがサイドパネルや表示パネルを容易に視認できるようにして 、る[0038] The side wall portion 17 is formed with an inclined surface that is directed downward toward the driver's seat 12 side. The seated operator can easily see the side panel and display panel.
。そして、側壁部 17の右前端は前記上部カバー 32に向かって延出され、該側壁部 1 7の上面部が描く曲線の延長線上に、該上部カバー 32の左上面部が繋がるようにし て、側壁部 17と上部カバー 32が連続した形状となるようにして、意匠性を向上させて いる。 . The right front end of the side wall portion 17 extends toward the upper cover 32, and the left upper surface portion of the upper cover 32 is connected to an extended line of a curve drawn by the upper surface portion of the side wall portion 17 so that the side wall portion 17 The design is improved by forming the portion 17 and the upper cover 32 into a continuous shape.
[0039] 一方、運転操作部 15の右側は、略中央から前方にかけて、すなわち、運転席 12と ステアリングコラム 9の間が開口部となっており、オペレータが運転操作部 15に搭乗 する際の乗降口となって 、る。  [0039] On the other hand, the right side of the driving operation unit 15 is an opening from approximately the center to the front, that is, between the driver's seat 12 and the steering column 9, and when the operator gets on and off the driving operation unit 15, It becomes the mouth.
[0040] 本発明に係るフロントカバー 30について、図 4乃至図 7を用いて説明する。ここで、 図 4、図 6、および、図 7に示す矢印 Aは進行方向前方を示し、該矢印 Aの方向に従 つて左右前後方向を定める。  [0040] The front cover 30 according to the present invention will be described with reference to FIGS. Here, the arrow A shown in FIG. 4, FIG. 6, and FIG. 7 indicates the front in the traveling direction, and the left and right front-rear directions are determined according to the direction of the arrow A.
フロントカバー 30を構成する上部カバー 32の上面部は、左右中央部を円弧形状 に下方に緩やかに凹ませた形状としており、該上面部の右端部 (乗降口側)にはダリ ップ部 33が立設されている。  The upper surface portion of the upper cover 32 constituting the front cover 30 has a left and right central portion that is gently depressed downward in an arc shape, and a drip portion 33 on the right end (entrance side) of the upper surface portion. Is erected.
[0041] また、平面視において、上部カバー 32の左右両端部は後方に向けて湾曲する形 状に形成している。換言すれば、上部カバー 32は、オペレータが運転席 12に着座し た状態で右分草板 13を視認する際に、その視線が上部カバー 32により遮られない ように、上部カバー 32の左側の前面は、図 13に示す如ぐ運転席 12に着座したオペ レータの目と右分草板 13を結ぶ線 Qに沿った形状として、できるだけ前方に膨らませ て、足元空間を広げて居住性を高め、更に、線 Qよりも下後方に位置するように形成 され、視認性を高めている。  [0041] In plan view, the left and right ends of the upper cover 32 are formed in a shape that curves backward. In other words, the upper cover 32 is provided on the left side of the upper cover 32 so that the line of sight is not obstructed by the upper cover 32 when the operator views the right weed board 13 while sitting on the driver's seat 12. The front is shaped along the line Q connecting the eyes of the operator seated in the driver's seat 12 as shown in Fig. 13 and the right weed board 13 and is inflated as far forward as possible to widen the foot space and enhance the comfort. In addition, it is formed so as to be located below and behind the line Q, thereby improving visibility.
また、上部カバー 32の右側の前面は、右分草板 13より右後方に延設したサイドデ バイダーを視認できるようにして、中割等が容易にできるようにして 、る。  In addition, the front surface on the right side of the upper cover 32 is designed so that a side divider extending to the right rear side from the right weed board 13 can be visually recognized, so that it can be easily divided.
[0042] すなわち、フロントカバー 30を上下に分割し、側面視において、下部カバー 31を略 垂直に立設し、上部カバー 32を後方へ傾斜させて構成し、平面視において、フロン トカバー 30の左側端部を後方に向けて湾曲形成する構成としている。  [0042] That is, the front cover 30 is divided into upper and lower parts, and the lower cover 31 is erected substantially vertically in the side view, and the upper cover 32 is inclined rearward, and the left side of the front cover 30 in the plan view. It is set as the structure which curves and forms an edge part toward back.
[0043] これにより、オペレータの視線がフロントカバー 30により遮られる範囲が減少するた め、オペレータが、運転席 12に着座した状態で、運転席 12に最も近い(最も右側の) 右分草板 13を容易に視認することができるのである。また、これにより、作業性を向 上させることができるのである。 [0043] This reduces the range in which the operator's line of sight is blocked by the front cover 30, so that the operator is closest to the driver's seat 12 in the state of being seated on the driver's seat 12 (rightmost). The right weed board 13 can be easily seen. This also improves workability.
[0044] 前記グリップ部 33は左右方向に延出される略筒形状の握り部 33aと、該握り部 33a と本体部 34とを繋ぐ支持部材 33bと、から構成されており、これら部材 33a ' 33b ' 34 が熱硬化性榭脂等により、一体にて形成されるため、部品点数が減り、経済的に優 れている。 [0044] The grip portion 33 includes a substantially cylindrical grip portion 33a extending in the left-right direction, and a support member 33b that connects the grip portion 33a and the main body portion 34. These members 33a'33b Since '34 is formed integrally with thermosetting resin, etc., the number of parts is reduced and it is economically superior.
また、後述のようにオペレータが運転操作部 15に乗り込む際には、支持部材 33bと 本体部 34との接続部において、大きな曲げ応力が発生する力 これら部材 33a ' 33 b · 34がー体成形されることにより、該応力に対する剛性を高めることができる。  Also, as described later, when the operator gets into the operation section 15, the force that generates a large bending stress at the connection between the support member 33b and the main body 34. These members 33a'33b As a result, the rigidity against the stress can be increased.
[0045] ここで、握り部 33aはステアリングノヽンドル 11の下方において十分な隙間を設けて 配置されており、また、図 6に示すように、該握り部 33aは平面視にて該ステアリング ハンドル 11の右側握り個所の直下近傍に設けられて 、る。  [0045] Here, the grip portion 33a is disposed below the steering handle 11 with a sufficient gap, and as shown in FIG. 6, the grip portion 33a is viewed from above in the plan view. It is located near the right hand grip of
このため、例えば、コンバイン 1の操作中に不意に横ブレ等を受けて体勢を崩しか けた場合には、咄嗟に右手をステアリングノヽンドル 11から握り部 33aに持ち替えて、 体勢を整えることができ、また、機体の旋回作業や畦越え作業等、不安定な作業を 行う場合には、握り部 33aを握り締めて操縦姿勢を保ちつつ、左手で該ステアリング ハンドル 11を操縦することができる。なお、右手でステアリングノヽンドル 11を操縦する 場合、左手は前記側壁部 17に設けたグリップを握り、体を支える。  For this reason, for example, if you suddenly receive a lateral shake during the operation of combine 1 and your posture is lost, you can move your right hand from the steering handle 11 to the grip 33a to prepare your posture. In addition, when performing unstable work such as turning of the fuselage or crossing the heel, the steering handle 11 can be steered with the left hand while the grip 33a is held tightly to maintain the steering posture. When steering the steering needle 11 with the right hand, the left hand holds the grip provided on the side wall portion 17 to support the body.
[0046] 握り部 33aの前後両面部には、左右方向に並べた複数の窪み (膨らみであってもよ い) 35 · 35 · · ·が縦長に伸びる楕円形状を有して配置されており、オペレータは該窪 み 35 · 35 · · ·に沿って指を添えることにより、滑ることなく容易に適切な位置にて該握 り部 33aを握り締めることができる。  [0046] On both front and rear side portions of the grip portion 33a, a plurality of depressions (which may be bulges) arranged in the left-right direction are arranged with an elliptical shape extending vertically. The operator can easily grip the grip portion 33a at an appropriate position without slipping by putting his / her finger along the recess 35 · 35 ···.
[0047] このような形状を有してグリップ部 33が上部カバー 32の上端部右側、すなわち、運 転席 12への乗降口側に設けられること〖こより、オペレータは運転操作部 15へ乗り込 む際、不安定なステアリングノヽンドル 11等を握って体重を預けることもなぐ該グリツ プ部 33の握り部 33aを握ることで、安定した搭乗姿勢を保持することができ、カロえて、 運転席 12に腰を降ろすと同時に即座に該ステアリングノヽンドル 11に持ち替えること ができる。 [0048] また、グリップ部 33は上述のとおり、運転操作部 15への乗り込む際に必要となる、 上部カバー 32の上端部右側に限定して設けられているため、コンバイン 1の前方下 方に関しては妨げとならず、また、乗降時には瞬時にグリップ部 33の存在を視認する ことができる。 [0047] With this shape, the grip portion 33 is provided on the right side of the upper end portion of the upper cover 32, that is, on the entrance / exit side to the driver's seat 12, so that the operator gets into the driving operation portion 15. In this case, it is possible to maintain a stable riding posture by holding the grip part 33a of the grip part 33 that holds the unstable steering wheel handle 11 etc. At the same time as sitting down at 12, it can be switched to the steering needle 11 immediately. [0048] Further, as described above, the grip portion 33 is provided only on the right side of the upper end portion of the upper cover 32, which is necessary when getting into the driving operation portion 15. In addition, the presence of the grip portion 33 can be visually recognized at the time of getting on and off.
[0049] さらに、グリップ部 33の握り部 33aは左右方向に延出する略筒形状に形成されるた め、オペレータが運転席へ乗り込むために手で握った際、手中になじんで握りやすく 、上述のように握り部 33aの前後両側面部において、複数の窪み 35 · 35 · · ·を設けた ことにより、オペレータは上部カバー 32の斜め前方、あるいは、斜め後方の両方向か ら、該握り部 33aを握り、安定した姿勢を保持しながら運転席 12に搭乗することがで きる。  [0049] Further, since the grip portion 33a of the grip portion 33 is formed in a substantially cylindrical shape extending in the left-right direction, when the operator grasps with his hand to get into the driver's seat, the grip portion 33a is familiar with the hand and is easy to grip. As described above, by providing a plurality of depressions 35 · 35 ··· at both the front and rear side portions of the grip portion 33a, the operator can operate the grip portion 33a from both the diagonally forward and diagonal directions of the upper cover 32. You can board the driver's seat 12 while holding a stable position.

That is, the tangential direction at the thumb position when grasped. Accordingly, the operator can safely perform the combine operation without greatly losing his / her posture, stress applied to the thumb, and the grip body 41 of the steering handle 11 being clamped.
[0055] 張り出し部 41Rの後方外側 (右側)には、略矩形形状を有して緩やか後方へと伸び る張り出し部 22が設けられており、その上下面部は平面形状となっている。また、前 記張り出し部 22の上面部には、矩形形状の窪み 24が設けられている。  [0055] On the rear outer side (right side) of the overhanging portion 41R, an overhanging portion 22 having a substantially rectangular shape and extending gently rearward is provided, and the upper and lower surface portions thereof are planar. Further, a rectangular recess 24 is provided on the upper surface portion of the overhang portion 22.
[0056] 更に、張り出し部 41Rの後方には、前記グリップ本体 41の下面から内側 (左側)側 面に向力つて伸びる膨らみ(凹みであってもよ 、) 23 - 23 - 23が前後方向に並列して 設けられている。  [0056] Further, on the rear side of the overhanging portion 41R, a bulge (which may be a dent) extending from the lower surface of the grip body 41 toward the inner side (left side) is provided in the front-rear direction. It is provided in parallel.
[0057] 左側の張り出し部 41Lは左右両側に向力つて若干内側 (右側)に大きく丸みを帯び ながら張り出しており、かつ、該張り出し部 41Lの上下面部は平らな面が形成されて いる。また、該張り出し部 41Lの上面部には、中央より略左方(内側)に窪み 45が設 けられている。さらに、前記張り出し部 41Rと同様に、張り出し部 41Lの後方には、前 記グリップ本体 41の下面から内側 (右側)側面に向力つて伸びる膨らみ 23 · 23 · 23が 前後方向に並列して設けられて 、る。  [0057] The left overhanging portion 41L is bulging slightly toward the inside (right side) by applying force to the left and right sides, and the upper and lower surfaces of the overhanging portion 41L are flat. In addition, a recess 45 is provided on the upper surface of the overhanging portion 41L substantially to the left (inside) from the center. Further, as in the case of the overhanging portion 41R, bulges 23, 23, and 23 that extend from the lower surface of the grip body 41 toward the inside (right) side surface are provided in parallel in the front-rear direction behind the overhanging portion 41L. Being
[0058] このような形状にグリップ本体 41を形成することにより、オペレータはステアリングノヽ ンドル 11のグリップ本体 41を握る際には、左右に設けられる前記複数の膨らみ部 23 •23 · · ·の間隙部に指を添えて、適切な位置にて該グリップ本体 41を握ることができ 、滑りを防止できると同時に、前記張り出し部 41Lと、前記張り出し部 22との上面部 にそれぞれ設けられる窪み 45 · 24に親指を添えることによって、強固に該グリップ本 体 41を握ることができる。  [0058] By forming the grip body 41 in such a shape, when the operator grips the grip body 41 of the steering handle 11, the gaps between the plurality of bulging portions 23 provided on the left and right are provided. The grip body 41 can be gripped at an appropriate position with a finger attached to the part, and slipping can be prevented, and at the same time, depressions provided on the upper surface parts of the overhanging part 41L and the overhanging part 22 By attaching a thumb to 24, the grip body 41 can be firmly held.
[0059] ここで、前記張り出し部 41Rと張り出し部 41Lとの前後の位置関係を比較した場合 、前記張り出し部 41Rの方が前方になるように設けられている。すなわち、ステアリン グハンドル 11にお 、て、グリップ本体 41は平面視にて進行方向前方部を除去した略 半円形を有しており、その右端部は左端部に比べて前方に延出して形成されて!、る 換言すれば、ステアリングノヽンドル 11の左端部を右端部に比して短く形成しており 、オペレータの前方左下方向の視界を遮る範囲を極力少なくするという利点を有した 形状としている。 [0059] Here, when comparing the front-rear positional relationship between the overhanging portion 41R and the overhanging portion 41L The overhanging portion 41R is provided in front. That is, in the steering handle 11, the grip body 41 has a substantially semicircular shape in which the front portion in the traveling direction is removed in plan view, and the right end portion is formed to extend forward as compared with the left end portion. In other words, the left end portion of the steering handle 11 is formed shorter than the right end portion, and has a shape that has the advantage of minimizing the range that obstructs the view of the operator in the lower left direction. .
[0060] すなわち、ステアリングノヽンドル 11を、平面視略 U字形状に形成し、ステアリングノヽ ンドル 11の前端を、フロントカバー 30 (上部カバー 32)の左右両側上方に配置する 構成としている。  That is, the steering handle 11 is formed in a substantially U shape in plan view, and the front end of the steering handle 11 is arranged above the left and right sides of the front cover 30 (upper cover 32).
これにより、オペレータの視線がステアリングノヽンドルにより遮られる範囲が減少す るため、オペレータが、運転席 12に着座した状態で、運転席 12に最も近い(最も右 側の)右分草板 13を容易に視認することができるのである。また、これにより、作業性 を向上させることができるのである。  As a result, the range in which the operator's line of sight is blocked by the steering handle is reduced, so that the operator is seated on the driver's seat 12 and the right weed board 13 closest to the driver's seat 12 (the rightmost) is removed. It can be easily visually recognized. In addition, this makes it possible to improve workability.
[0061] 小型(2条刈ゃ 3条刈)のコンバイン 1では通例、刈取部 4が機体の左側に、また、運 転操作部 15が該機体の右側に配置して構成される。そのため、通常の刈取作業で は、機体は左周りで未刈穀稈を順次刈り取って行くことになる。 [0061] In a small-sized (two-row, three-row) combine 1, the mowing unit 4 is usually arranged on the left side of the aircraft and the operation unit 15 is arranged on the right side of the aircraft. Therefore, in normal harvesting operations, the aircraft will sequentially harvest uncut cereals around the left.
この際、刈取部 4の右前下部に設けられる右分草板 13を条間または右側の未刈穀 稈の株元に合わせて刈り取る力 ステアリングノヽンドル 11のグリップ本体 41を本実施 例における形状とすることにより、右分草板 13の近傍の視認性が向上し、刈取部 4を 条に対して適切に位置合わせをすることが容易となるため、刈残しを発生させる心配 もないのである。  At this time, the right weed plate 13 provided at the lower right front part of the cutting part 4 is the power to cut the right weed plate 13 according to the stock of the uncut sorghum on the right side or the right side. The grip body 41 of the steering wheel 11 is By doing so, the visibility in the vicinity of the right weed board 13 is improved, and it becomes easy to properly position the cutting part 4 with respect to the strip, so there is no fear of generating uncut leaves.
[0062] ボス部材 42は直立した筒形状として内部にナット等を組み込んで、ステアリングシ ャフトに組み付けられるようにしている。該ボス部材 42と前記グリップ本体 41は支持 部材 43により連結されている。該支持部材 43は平面視略 T字状に構成し、側面視 略 L字状に構成している。すなわち、支持部材 43の左右中央より前方に向力つて連 結部 43aを延出させて、前記ボス部材 42の後面に固設している。また、支持部材 43 •43の左右両側は前記グリップ本体 41の後部下面に連結されている。 [0063] 支持部材 43は連結部 43aの後部左右両側面部から両外側に向かって緩やかに湾 曲しながら斜上方へと延出し、グリップ本体 41の下面と繋がっている。 [0062] The boss member 42 has an upright cylindrical shape, and a nut or the like is incorporated therein so that the boss member 42 can be assembled to the steering shaft. The boss member 42 and the grip body 41 are connected by a support member 43. The support member 43 has a substantially T shape in plan view and a substantially L shape in side view. That is, the connecting portion 43a is extended forward from the left and right center of the support member 43 and fixed to the rear surface of the boss member 42. The left and right sides of the support members 43 and 43 are connected to the lower surface of the rear portion of the grip body 41. [0063] The support member 43 extends obliquely upward from the left and right side surfaces of the rear portion of the connecting portion 43a toward the both sides and extends obliquely upward, and is connected to the lower surface of the grip body 41.
[0064] ここで、支持部材 43がグリップ本体 41の下面と繋がる個所は、平面視にて該グリツ プ本体 41の後部付近に配置されており、該グリップ本体 41において、前記両張り出 し部 41R'41Lと支持部材 43との間には所定長さの握り部が形成されている。すなわ ち、握り部は図 10に示すように、ほぼ成人の手の幅に比べて若干大きな寸法 X(右 側)、および、寸法 Y (左側)が設定されている。  Here, the portion where the support member 43 is connected to the lower surface of the grip body 41 is disposed in the vicinity of the rear portion of the grip body 41 in a plan view. A grip portion having a predetermined length is formed between 41R′41L and the support member 43. In other words, as shown in Fig. 10, the grip portion is set to have dimensions X (right side) and Y (left side) that are slightly larger than the width of an adult's hand.
[0065] このような構成を有することにより、オペレータがステアリングハンドル 11のグリップ 本体 41を握る際は、容易に適切な位置にて握ることができ、他に不適切な個所を握 ろうとしても、支持部材 43が妨げとなり、防ぐことができる。  [0065] With this configuration, when the operator grips the grip body 41 of the steering handle 11, the operator can easily grip the grip body 41 at an appropriate position. The support member 43 becomes an obstacle and can be prevented.
[0066] また、グリップ本体 41の後方は、前記二本の支持部材 43 · 43との両接続個所の間 において、前方に歪ませた緩やかな(曲率半径が大きい)円弧形状となっており、運 転席 12と、ステアリングノヽンドル 11との間隔を十分に確保することができ、オペレータ が運転席 12に着座した状態でも大腿部の上方は開放されるため、ステアリングノヽン ドル 11の横側方や、斜後方に一旦起立し、その後、体を捻りながらシート部に潜り込 む等することなぐ運転席 12への搭乗作業を容易に行うことができる。  [0066] The rear side of the grip body 41 has a gentle arc shape (large radius of curvature) that is distorted forward between the connection points of the two support members 43 and 43. The space between the driver's seat 12 and the steering wheel 11 can be sufficiently secured, and the upper part of the thigh is opened even when the operator is seated on the driver's seat 12, so that the side of the steering wheel 11 can be It is possible to easily perform the boarding operation to the driver's seat 12 without standing up to the side or obliquely backward and then entering the seat portion while twisting the body.
[0067] また、オペレータがステアリングノヽンドル 11を旋回操作するには、一方の端部を前 方に引き出し、他端部を後方へと引き込むが、この際、勢い余って片側の手が前方 へ滑り抜けようとしても、前記張り出し部がストッパーとなって滑り抜けることはなぐま た、支持部材 43の妨げにより、引き込もうとした手が誤って後方に滑る心配もない。  [0067] In addition, in order for the operator to turn the steering handle 11, the one end is pulled forward and the other end is pulled backward. At this time, one hand moves forward with excessive force. Even if it tries to slip through, the overhanging portion does not slide out as a stopper, and the support member 43 prevents the hand trying to pull in accidentally slipping backward.
[0068] 次に、オペレータの視線と機体各部との関係について、図 13または図 14を用いて 説明をする。  Next, the relationship between the operator's line of sight and each part of the airframe will be described with reference to FIG. 13 or FIG.
図 13に示す如ぐ従来は、ステアリングノヽンドル 11の前端部により視線が遮られる ため、図 13中の線 Pで示す視線でなければ右分草板 13を視認することができず、右 分草板 13を視認する際には必然的にオペレータは、床部 10上で立ち上がる必要が めつに。  Conventionally, as shown in FIG. 13, since the line of sight is blocked by the front end of the steering handle 11, the right weed board 13 cannot be seen without the line of sight indicated by line P in FIG. When viewing the grass board 13, the operator must stand up on the floor 10 inevitably.
図 13に示す如ぐそれに対して、本実施例に示すステアリングノヽンドル 11およびフ ロントカバー 30の形状とすれば、右側面視において、オペレータが右分草板 13を注 視する際の視線は、図 13中の線 Qで示す視線とすることが可能となり、視線がステア リングノヽンドル 11や上部カバー 32に遮られることがなぐオペレータは運転席 12に 着座した状態で右分草板 13を容易に視認可能であることが確認できる。 On the other hand, if the shape of the steering handle 11 and the front cover 30 shown in the present embodiment is used as shown in FIG. 13, the operator inserts the right weed board 13 in the right side view. The line of sight at the time of viewing can be the line of sight indicated by line Q in FIG. 13, and an operator whose line of sight is not blocked by the steering handle 11 or the upper cover 32 is seated in the driver's seat 12. It can be confirmed that the right weed board 13 is easily visible.
[0069] また、図 14に示す如ぐ本実施例に示すステアリングハンドル 11およびフロントカバ 一 30の形状とすれば、平面視においては、オペレータが右分草板 13を注視する際 の視線は、図 14中の線 Rで示す視線となり、視線がステアリングノヽンドル 11や上部力 バー 32に遮られることがなぐオペレータは運転席 12に着座した状態で右分草板 13 を容易に視認可能であることが確認できる。  [0069] If the shape of the steering handle 11 and the front cover 30 shown in this embodiment as shown in FIG. 14 is used, the line of sight when the operator gazes at the right weed board 13 in plan view is An operator whose line of sight is indicated by a line R in FIG. 14 and is not obstructed by the steering handle 11 or the upper force bar 32 can easily see the right weed board 13 while sitting on the driver's seat 12. I can confirm that.
[0070] すなわち、ステアリングノヽンドル 11を平面視略 U字形状に形成し、ステアリングノヽン ドル 11の前端部をフロントカバー 30の左右両側上方に配置し、かつ、フロントカバー 30を上下に分割し、側面視において、下部カバー 31を略垂直に立設し、上部カバ 一 32を後方へ傾斜させて構成し、平面視において、フロントカバー 30の左側端部を 後方に向けて湾曲形成するとともに、上部カバー 32の前面延長上にステアリングノヽ ンドル 11の前端を配置する構成とすることにより、オペレータの視線がステアリングノヽ ンドル 11やフロントカバー 30により遮られる範囲が減少するため、オペレータが、運 転席 12に着座した状態で、運転席 12に最も近い(つまり、最も右側の)右分草板 13 を容易に視認することができるのである。また、これにより、作業性を向上させることが できるのである。  That is, the steering handle 11 is formed in a substantially U shape in plan view, the front end portion of the steering handle 11 is disposed above both the left and right sides of the front cover 30, and the front cover 30 is divided into upper and lower parts. In the side view, the lower cover 31 is erected substantially vertically, and the upper cover 32 is inclined rearward. In the plan view, the left end of the front cover 30 is curved toward the rear, and By arranging the front end of the steering wheel 11 on the front extension of the upper cover 32, the range in which the operator's line of sight is blocked by the steering wheel 11 and the front cover 30 is reduced. The right weed board 13 closest to the driver's seat 12 (that is, the rightmost side) can be easily seen while sitting on the seat 12. In addition, this makes it possible to improve workability.
実施例 2  Example 2
[0071] 次に、本発明の別実施例に係るステアリングノヽンドルの構造について、図 15乃至 図 18により説明する。  Next, the structure of a steering handle according to another embodiment of the present invention will be described with reference to FIGS.
[0072] 従来の回転式ステアリングノ、ンドルは、その形状を略円形状としていたために、作業 時において、運転者が運転シートに座って走行しながら運転部前方の刈取部を見て 、圃場の穀桿の未刈部と刈取収穫物の流れを確認する場合、丸型ハンドルが運転 者の視線の前方に位置し、視界を遮り作業しづらくなるといった問題もあった。  [0072] Since the conventional rotary steering wheel and handle have a substantially circular shape, the driver can sit on the driver's seat and look at the cutting part in front of the driver while working. When confirming the uncut part of cereal grains and the flow of harvested crops, the round handle is located in front of the driver's line of sight, which obstructs the view and makes it difficult to work.
具体的には、左旋回する際、図 18に示すように、運転者の身長 ·姿勢によっては、 従来の丸型ステアリングノヽンドル 11Aを回すとハンドル前方部が邪魔になり運転部 前方の刈取部 4 (特に右分草板 13)が見えず、穀桿等の刈り残しを視認'確認できな ヽことがあった。 Specifically, when turning counterclockwise, as shown in FIG. 18, depending on the height and posture of the driver, turning the conventional round steering wheel 11A obstructs the front part of the steering wheel and cuts the front part of the driving part. 4 (Especially right weed board 13) There was a habit.
特にコンバインの場合には、通例、刈取部 4が左で運転席 12が右に配置される構 成のため、機体の左側に存在する未刈穀稈を順次刈り取つていくものであり、右分草 板より右側へはみだした未刈穀稈はメ IJり残しとなってしまう。つまり、右分草板 13が 見えないと、刈り残しを発生させる恐れがある。  Especially in the case of a combine, the harvesting unit 4 is usually arranged on the left and the driver's seat 12 is arranged on the right. Uncut cereals that protrude to the right of the weed board will leave behind. In other words, if the right weed board 13 is not visible, there is a risk that uncut cutting will occur.
[0073] そこで、本発明は、視認性の優れた、特に、左旋回時に穀桿等の刈り残しが確認で きるように、運転部前方の刈取部(特に右分草板)を視認 '確認できるようにハンドル 前方部を除去した構造のステアリングノヽンドルを提供する。  [0073] Therefore, the present invention is excellent in visibility, and in particular, visually confirms the cutting part (especially the right weed board) in front of the driving part so that a leftover cutting such as cereal can be confirmed when turning left. A steering handle having a structure in which the front part of the steering wheel is removed is provided.
[0074] 図 16においては、二点鎖線のステアリングハンドル 11Aは従来の丸型ハンドルを、 実線のステアリングノヽンドル 11は本発明に係るステアリングノヽンドルを示してあり、そ れぞれ比較するため重ねている。ステアリングハンドルを、該ステアリングノヽンドルの 前後方向の半分より略前方部を除去したものが、本発明に係るステアリングノ、ンドル 11である。  In FIG. 16, a two-dot chain steering handle 11A is a conventional round handle, and a solid steering handle 11 is a steering handle according to the present invention, which are overlapped for comparison. ing. The steering handle 11 according to the present invention is obtained by removing the front portion of the steering handle from the half in the front-rear direction of the steering handle.
そして、図 15に示すように、本発明に係るステアリングノヽンドル 11において、ハンド ル前方部を除去して残ったノ、ンドル握り部の左右両先端に張り出し部 41い 41R (本 実施例では、ハンドル内側に向けて張り出して 、る)を設ける構成として 、る。  Then, as shown in FIG. 15, in the steering handle 11 according to the present invention, the left and right ends of the handle grip part left after removing the handle front part 41 and 41R (in this embodiment, This is a structure in which it protrudes toward the inside of the handle.
[0075] 該張り出し部 41Rには、後述する操作スィッチ 21ゃ該スィッチを説明するイラストを 印刷した窪み 25や指 (例えば親指)を置く窪み 24等が設けられている。 [0075] The overhanging portion 41R is provided with a depression 25 on which an operation switch 21 described later is printed with an illustration explaining the switch, a depression 24 on which a finger (for example, a thumb) is placed, and the like.
また、張り出し部 41Rからステアリングノヽンドル 11後部にかけての弧状の左右角部 に膨らみ 50が形成されて 、る。  Further, bulges 50 are formed at the left and right corners of the arc shape from the overhanging portion 41R to the rear portion of the steering handle 11.
すなわち、ステアリングノヽンドル 11の前後方向の半分より後方の握り部において、 握り部の一部に大径部を設けるものであり、この大径部である膨らみ 50は、握り部の 径を連続的に大径にした部分である。  That is, a large diameter portion is provided at a part of the grip portion at the grip portion behind the front / rear direction of the steering wheel 11, and the bulge 50, which is the large diameter portion, continuously increases the diameter of the grip portion. It is the part which made the diameter larger.
[0076] 結果として、ステアリングノヽンドルの前方部が除去されたことにより、運転者から見て 前方、特に左旋回時は左前下方の視界が広くなるので、運転者が運転席 12に座つ て走行しながらも運転部 15前方の刈取部 4 (詳しくは右分草板 13)を見て、最未刈部 の刈取収穫物の流れを確認し易くなり、作業効率と安全性が向上するのである。 また、ステアリングノヽンドル 11の左右前端部に設けられ、本実施例ではハンドル内 側に張り出された張り出し部 41R.41L力 ステアリングノヽンドル 11操作時の手の抜 け防止の効果を奏する。 [0076] As a result, since the front part of the steering handle is removed, the field of view forward, especially the left front lower side when turning left, is widened so that the driver sits on the driver's seat 12. While driving, see the cutting part 4 in front of the driving part 15 (specifically, the right weed board 13), which makes it easier to check the flow of the harvested parts in the most uncut part, which improves work efficiency and safety. is there. In addition, it is provided at the left and right front ends of the steering handle 11, and in this embodiment, 41R.41L force that protrudes to the side Steering handle 11 Has the effect of preventing hand pulling during operation.
[0077] 次に、前記張り出し部の構成について説明する。 Next, the configuration of the overhanging portion will be described.
[0078] 詳しくは、該張り出し部 41Rに平面状のスペースを設け、該スペースに矩形状の凹 みを設け、該凹みに警報器や刈取昇降用や操向微調整用等の各種作業機構の操 作を行う操作スィッチ 21を配設する。この際、該操作スィッチ 21上端が断面視ステア リングノヽンドル 11本体より突出しな 、ように構成する(図 17参照)。このように操作スィ ツチ 21上端が突出しないように構成するのは、コンバインを圃場等に待機させる際に シート等の覆いでカバーしたときに、操作スィッチ 21がハンドル上面より突出している とシートがひつ力かり操作スィッチ 21が破損してしまう可能性があり、または、咄嗟の 場合にその箇所を掴んだときに怪我をする、あるいは誤操作してしまう恐れもあり、そ れらを防ぐためである。  [0078] Specifically, a flat space is provided in the overhanging portion 41R, a rectangular recess is provided in the space, and an alarm device, a lifting / lowering for cutting and a fine steering adjustment are provided in the recess. An operation switch 21 is provided for operation. At this time, the operation switch 21 is configured so that the upper end of the operation switch 21 does not protrude from the steering handle 11 main body in cross section (see FIG. 17). In this way, the upper end of the operation switch 21 is configured not to protrude when the combine is covered with a cover such as a seat when the combine is kept on the field or the like, and the operation switch 21 protrudes from the upper surface of the handle. This is to avoid the possibility that the operating force switch 21 may be damaged, or that it could be injured or misoperated when holding the part in the case of a heel. .
また、前記張り出し部 41Rの先端表面には該操作スィッチ 21の効果若しくは操作 方法を示した窪み 25や線や矢印や目盛り等を刻設したり印刷等を施して 、る。 本実施例では、右側の張り出し部 41Rには、手動操作にて刈取部を昇降して刈り 高さを任意に調節可能とする刈り取り高さ調節スィッチを具備させ、先端表面の該ス イッチの説明イラストを印刷して 、る。  Further, a depression 25, a line, an arrow, a scale, or the like indicating the effect of the operation switch 21 or the operation method is engraved or printed on the tip surface of the overhanging portion 41R. In the present embodiment, the right overhanging portion 41R is provided with a cutting height adjustment switch that allows the cutting height to be arbitrarily adjusted by raising and lowering the cutting portion by manual operation, and the switch on the tip surface is described.
