JP 2001-222333 A

しかしながら、上記構成の復元機構は、弾性支持ローラと特殊形状のカムとによる複雑な部材構成が避けられないことから、生産コスト、メンテナンス、特性設定の点で問題が残っており、構成の簡易化が望まれていた。   However, since the restoration mechanism with the above configuration cannot avoid the complicated member configuration with the elastic support roller and the specially shaped cam, problems remain in terms of production cost, maintenance, and characteristic setting, and the configuration is simplified. Was desired.

本発明の目的は、簡易な装置構成により、生産コスト、メンテナンス、特性設定の点で支持の得られる操向操作装置を提供することにある。   An object of the present invention is to provide a steering operation device that can obtain support in terms of production cost, maintenance, and characteristic setting with a simple device configuration.

請求項1に係る発明は、操向用レバー(1)を中立位置(N)から左右に傾倒可能に支持し、上記操向用レバー(1)は、その傾倒操作に対して抵抗力を作用する抵抗機構(5)を備え、この抵抗機構(5)は、操向用レバー(1)と一体で該操向用レバー(1)の傾倒中心軸線に対して左右対称位置に突出形成した2つの突出部(15)と、これら2つの突出部(15)に当接して抵抗力を作用させる弾性部材(14)とからなり、この弾性部材(14)は、作用点が左右対称配置で弾性特性が互いに異なる2つの弾発部(14L、14R)を一体に構成してなることを特徴とする。   The invention according to claim 1 supports the steering lever (1) so as to be tiltable to the left and right from the neutral position (N), and the steering lever (1) acts on the tilting operation. This resistance mechanism (5) is formed integrally with the steering lever (1) so as to protrude in a bilaterally symmetrical position with respect to the tilting central axis of the steering lever (1). It consists of two protrusions (15) and an elastic member (14) that abuts against these two protrusions (15) and acts on the resistance, and this elastic member (14) is elastic with its action point symmetrically arranged. Two elastic portions (14L, 14R) having different characteristics are integrally formed.

上記抵抗機構は、作用点が左右対称で弾性特性が異なる2つの弾発部を一体構成した弾性部材を備えることから、2つの弾発部のみが左右非対称で操向操作装置の全体構成を左右対称に構成することができる。   Since the resistance mechanism includes an elastic member that integrally includes two elastic portions having symmetrical left and right action points and different elastic characteristics, only the two elastic portions are left-right asymmetric, and the overall configuration of the steering operation device is left and right. It can be configured symmetrically.

請求項2に係る発明は、請求項1の構成において、前記抵抗機構の2つの弾発部(14L、14R)は、操向用レバー(1)の2つの突出部(15)に対して所定の隙間(S)を設けたことを特徴とする。
上記操向用レバーの操作が所定の傾倒範囲を越えると抵抗機構が作用することから、左右復元機構とにより2段階の傾倒特性となる。
According to a second aspect of the present invention, in the configuration of the first aspect, the two resilient portions (14L, 14R) of the resistance mechanism are predetermined with respect to the two protruding portions (15) of the steering lever (1). A gap (S) is provided.
When the operation of the steering lever exceeds a predetermined tilt range, the resistance mechanism acts, so that a two-stage tilt characteristic is obtained by the left / right restoring mechanism.

請求項1の発明の抵抗機構は、弾性部材の2つの弾発部のみが左右非対称で操向操作装置の全体構成を左右対称に構成することができることから、左右対称の簡易な構成の操向用レバーにより、傾倒特性が左右非対称の操向操作装置を構成することができる。   In the resistance mechanism of the invention of claim 1, since only the two elastic portions of the elastic member are asymmetrical left and right, and the entire configuration of the steering operating device can be configured symmetrically, the steering of a simple configuration that is symmetrical left and right By using the lever, it is possible to configure a steering operation device whose tilt characteristics are asymmetrical.

請求項2の発明は、操向用レバーの操作が所定の傾倒範囲を越えると抵抗機構が作用することから、左右復元機構と合わせた2段階の傾倒特性により、設定の自由度が確保される。   In the invention of claim 2, since the resistance mechanism acts when the operation of the steering lever exceeds a predetermined tilt range, a two-stage tilt characteristic combined with the left / right restoring mechanism ensures a degree of freedom of setting. .

上記技術思想に基づいて具体的に構成された実施の形態について以下に図面を参照しつつ説明する。
図1は、本発明の操向操作装置を適用したコンバインの操向操作装置の側面図(a)および正面図(b)である。
コンバインの操向操作装置は、直立姿勢の操向用レバー1を中立位置Nから左右方向について傾倒可能に前後方向配置の支軸2によって支持し、さらに、この支軸2のホルダー2hを前後方向について傾倒可能に左右方向配置の支軸3によって軸支することにより、同操向用レバー1を左右方向と前後方向について傾倒可能に構成する。
Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
FIG. 1 is a side view (a) and a front view (b) of a steering operation device for a combine to which the steering operation device of the present invention is applied.
The combine steering operation device supports a steering lever 1 in an upright posture by a support shaft 2 arranged in the front-rear direction so as to be tiltable from the neutral position N in the left-right direction, and further supports a holder 2h of the support shaft 2 in the front-rear direction. The steering lever 1 is configured to be tiltable in the left-right direction and the front-rear direction.

左右動作用の支軸2のホルダー2hには、操向用レバー1と連結してその左右傾倒位置から中立位置Nまで復元力を作用する左右復元機構4および、左右の傾倒操作について異なる抵抗力を作用する抵抗機構5を設け、また、前後動作用の支軸3のホルダー3hと連結して操向用レバー1の前後の傾倒位置から中立位置Nまで復元力を作用する前後復元機構6を設けることにより、操向用レバー1について、左右操作による走行機体の操向操作と前後操作による刈取部の昇降操作とを可能とする。   The holder 2h of the support shaft 2 for left / right operation is connected to the steering lever 1 and applies a restoring force from the left / right tilt position to the neutral position N, and different resistance forces for the left / right tilt operation. And a front / rear restoring mechanism 6 for acting a restoring force from the front / rear tilt position of the steering lever 1 to the neutral position N by being connected to the holder 3h of the support shaft 3 for front / rear operation. By providing the steering lever 1, it is possible to perform a steering operation of the traveling machine body by a left-right operation and a lifting operation of the cutting unit by a front-back operation.

詳細に説明すると、操向用レバー1は、作業者が操作するためのグリップGを頂部に備え、また、接続プレート11を基部に取付け、この接続プレート11を前後方向配置の支軸2に軸支することによって左右に傾倒可能に構成する。
左右復元機構4は、支軸2のホルダー2hに取付けたコイルスプリング12を操向用レバー1側に連結して構成することにより、左右の傾倒位置に応じた復元モーメントを操向用レバー1に作用する。
More specifically, the steering lever 1 is provided with a grip G for operation by an operator at the top, and a connection plate 11 is attached to the base, and the connection plate 11 is attached to the support shaft 2 arranged in the front-rear direction. It can be tilted left and right by supporting it.
The left / right restoring mechanism 4 is configured by connecting a coil spring 12 attached to the holder 2h of the support shaft 2 to the steering lever 1 side, thereby providing the steering lever 1 with a restoring moment corresponding to the left / right tilt position. Works.

抵抗機構5は、操向用レバー1の傾倒操作に対して接続プレート11に抵抗力を及ぼす弾性部材14を左右動作用の支軸2のホルダー2hに取付けて構成する。接続プレート11には、その下端に作用力を受けるための2つの突出部15、15を形成し、この2つの突出部15、15は、操向用レバー1の中心軸線について左右対称位置に配置する。
弾性部材14は、図2の斜視図に示すように、接続プレート11の2つの突出部15、15の干渉動作に対して抵抗力を作用する2つの弾発部14L、14Rを備え、これら2つの弾発部14L、14Rは、左右対称に形成した取付部14bから偏心配置の支持部14sを介して左右に異なる長さA、Bの2つの板ばねを片持ちに一体形成したものであり、2つの突出部15、15と個々に対向する位置で干渉可能に、かつ、所定の隙間Sを確保して配置する。
The resistance mechanism 5 is configured by attaching an elastic member 14 that exerts a resistance force on the connection plate 11 to the tilting operation of the steering lever 1 to the holder 2h of the support shaft 2 for left and right operation. The connecting plate 11 is formed with two projecting portions 15 and 15 for receiving an acting force at the lower end thereof, and the two projecting portions 15 and 15 are arranged at symmetrical positions with respect to the central axis of the steering lever 1. To do.
As shown in the perspective view of FIG. 2, the elastic member 14 includes two elastic portions 14 </ b> L and 14 </ b> R that exert a resistance force against the interference operation of the two protruding portions 15 and 15 of the connection plate 11. The two elastic portions 14L and 14R are integrally formed by cantilevering two leaf springs having different lengths A and B on the left and right sides through a support portion 14s arranged eccentrically from a left and right mounting portion 14b. The two protrusions 15 and 15 are arranged so as to be able to interfere with each other at a position facing each other and with a predetermined gap S secured.

前後復元機構6は、前後動作用の支軸3を中心として左右動作用の支軸2のホルダー2hに取付けたコイルスプリング16を前後動作用の支軸3のホルダー3hに連結して構成することにより、前後の傾倒位置に応じた復元モーメントを操向用レバー1に作用する。   The front / rear restoring mechanism 6 is configured by connecting a coil spring 16 attached to the holder 2h of the support shaft 2 for left / right operation around the support shaft 3 for front / rear operation to the holder 3h of the support shaft 3 for front / rear operation. Thus, a restoring moment corresponding to the front and rear tilt positions is applied to the steering lever 1.

上記構成の抵抗機構5は、右手操作の例について説明すると、弾性部材14の右側の弾発部14Rの弾性率を左側より小さく設定することにより、操向用レバー1の中立位置Nから右方の傾倒操作について左方操作より小なる抵抗力が作用することから、操作腕の掌側である正面内側方向への大なる筋力と甲側である右外側方向の小なる筋力との筋力差を補って左右同等の操作性を得ることができる。   The resistance mechanism 5 having the above-described configuration will be described with respect to an example of a right-hand operation. By setting the elastic modulus of the elastic portion 14R on the right side of the elastic member 14 to be smaller than that on the left side, the right side from the neutral position N of the steering lever 1 is set. Since a smaller resistance force acts on the tilting operation than the left operation, the difference in strength between the large muscular strength in the front inward direction which is the palm side of the operating arm and the small muscular strength in the right outer direction which is the back side By supplementing, the same operability can be obtained.

また、操向用レバー1の左右の傾倒操作による復元力は、操向用レバー1の左右の傾倒操作により接続プレート11の2つの突出部15、15が所定の隙間Sを越える範囲において弾性部材14によって抵抗力が作用することから、図3の特性図に示すように、操向用レバー1の操作力が所定の操作力を越える範囲について左右復元機構4の復元力F0と抵抗機構5による左右の抵抗力F1、F2が重なる2段階特性となり、隙間Sの設定と対応する範囲について左右の操作力の調節が可能となる。   Further, the restoring force by the left / right tilting operation of the steering lever 1 is an elastic member in a range where the two protruding portions 15, 15 of the connection plate 11 exceed the predetermined gap S by the left / right tilting operation of the steering lever 1. 14, the resistance force acts. As shown in the characteristic diagram of FIG. 3, the restoring force F0 of the left / right restoring mechanism 4 and the resistance mechanism 5 are within a range where the operating force of the steering lever 1 exceeds a predetermined operating force. The left and right resistance forces F1 and F2 have a two-step characteristic, and the left and right operating forces can be adjusted in a range corresponding to the setting of the gap S.

また、弾性部材14の2つの弾発部14L、14Rは、板ばねの長さによって左右非対称の弾性特性を簡易に設定することができ、この左右の異なる抵抗力を左右対称位置に作用するとともに、支持部14sが左右対称であることから、この操向操作装置は、全体が左右対称の構成により左右非対称の傾倒特性を簡易に構成することができる   Further, the two elastic portions 14L and 14R of the elastic member 14 can easily set the left-right asymmetric elastic characteristics depending on the length of the leaf spring, and the right and left different resistance forces act on the left-right symmetrical position. Since the support portion 14s is bilaterally symmetric, this steering operation device can easily form a left-right asymmetric tilt characteristic with a bilaterally symmetric configuration as a whole.

次に、左右旋回時のブレーキ制御システムを構成するリリーフバルブについて説明する。
リリーフバルブ21は、その取付け側面図を図4に示すように、操向操作装置の左下に配置し、90度倒れた状態で取付け、操向用レバー1を左右に操作するとロッドによりリリーフバルブ21のスプール軸が操作されるように構成する。このように構成することによりリリーフバルブ21の配置のための自由度を確保することができ、操向用レバー1の前後左右の回動支点から離れた広いスペースを利用することができる。
Next, the relief valve constituting the brake control system at the time of turning left and right will be described.
As shown in FIG. 4, the relief valve 21 is arranged at the lower left of the steering operation device, mounted in a state of being tilted 90 degrees, and when the steering lever 1 is operated to the left and right, the relief valve 21 is operated by a rod. The spool shaft is configured to be operated. With this configuration, a degree of freedom for arranging the relief valve 21 can be ensured, and a wide space away from the front, rear, left and right pivots of the steering lever 1 can be used.

次に、運転台は、その要部斜視図および側面図を図5、図6にそれぞれ示すように、操作席の足元の前部中央付近に掻き込みペダル22を配置し、その前方範囲Cについてパネルカバー23を切欠いて構成する。この切欠いた範囲Cにより、オペレータがペダル22を踏み込み操作してもつま先がパネルカバー23に当たらないことから、先行構成例(例えば、特開2006−115740号公報や特開2003−143925号公報)の問題を解消して、支障なく操作することができる。   Next, as shown in FIGS. 5 and 6, respectively, the driver's cab is provided with a scraping pedal 22 in the vicinity of the front center of the foot of the operation seat. The panel cover 23 is cut away. Since the notched range C causes the operator to depress the pedal 22 and the toe does not hit the panel cover 23, for example, a prior configuration example (for example, Japanese Patent Laid-Open No. 2006-115740 and Japanese Patent Laid-Open No. 2003-143925). It is possible to solve this problem and operate without any problems.

また、操作席の足元前部には、オペレータが足を載せるためのサブステップ24を配置し、このサブステップ24は、操向用レバー1を有する操向操作装置の直下の範囲Dを切欠いて構成する。この切欠範囲Dにより、操向操作装置の近傍にオペレータが足を置いた場合でも膝の高さ位置が下がることから、操向操作装置の操向用レバー1を手前に引く操作(刈取部上げ)をしても、この操向用レバー1が膝に当たることなく、操作することができる。   In addition, a sub-step 24 for the operator to place his / her foot is arranged in front of the foot of the operation seat, and this sub-step 24 cuts out a range D immediately below the steering operating device having the steering lever 1. Constitute. This notch range D lowers the knee height even when the operator puts his or her foot near the steering operation device. Therefore, an operation of pulling the steering lever 1 of the steering operation device toward the front (lifting the cutting part) ), The steering lever 1 can be operated without hitting the knee.

次に、コンバインのモニター25は、例えば、特開2005−58175号公報に示す従来のアワーメーター(積算時間計)とは別に、モニターの見取図(a)、およびその累積積算表示例(b)を図7に示すように、任意に積算できる複数の積算時間計を設ける。積算時間計ナンバーを選択、決定することにより、選択したナンバーの積算時間計に時間が積算され、また、ナンバーを選択してリセットすると、選択したナンバーの積算時間計をリセットし、いずれの場合も従来のアワーメーター(積算時間計)は影響しないように構成する。
このような複数の積算時間計により、オペレータ毎にそれぞれの積算時間計を割り当てたり、作物別に割り当てることにより、より詳細な管理運営に役立てることができ、また、農家毎の使用時間を計測することも可能となる。
Next, the combine monitor 25 is, for example, a monitor sketch (a) and an example of the cumulative integration display (b) separately from the conventional hour meter (integrated hour meter) disclosed in JP-A-2005-58175. As shown in FIG. 7, a plurality of integrating hour meters that can be arbitrarily integrated are provided. By selecting and determining the accumulated hour meter number, the time is accumulated in the accumulated hour meter of the selected number, and when the number is selected and reset, the accumulated hour meter of the selected number is reset. The conventional hour meter (integrated hour meter) is configured not to be affected.
With these multiple accumulated hour meters, each accumulated hour meter can be assigned to each operator or assigned to each crop, which can be used for more detailed management operations, and the usage time for each farm can be measured. Is also possible.

また、上記モニター25の各積算時間計は、図7の個別積算表示例(c)に示すように、累計と個別のモード変更を可能に構成し、累計はその積算時間計ナンバーを選んでいる時のみ時間を積算し、個別は積算時間計ナンバーを選んだ時点からの時間を積算するように構成する。このように、累計積算が可能となることから、交換部品の時間を計ることも可能となる。   Further, as shown in the individual integrated display example (c) of FIG. 7, each integrated hour meter of the monitor 25 is configured to be able to change the total and individual modes, and the integrated hour meter number is selected for the total. The time is accumulated only at the time, and the individual time is accumulated from the time when the accumulated hour meter number is selected. As described above, since cumulative integration is possible, it is possible to measure the time for replacement parts.
