特開２００４−２６７０１８号公報JP 2004-267018 A

本発明の課題は、作物の先端部を切断処理する摘心装置を、対地面に対して略平行姿勢で昇降する昇降リンク機構部に装備することによって、摘心作業を能率よく行い、摘心作業用カッターの切断作用高さを自由に調整でき、また、昇降リンク機構の利用によって別の作業装置の装着容易化を図る。   An object of the present invention is to efficiently perform a pinching operation by installing a pinching device that cuts the tip of a crop in a lifting link mechanism that moves up and down in a substantially parallel posture with respect to the ground. The height of the cutting action can be freely adjusted, and the use of a lifting link mechanism makes it easier to attach another working device.

この発明は、上記課題を解決すべく次のような技術的手段を講じた。
すなわち、請求項１記載の本発明は、走行車体（１）の前部に装着され、昇降シリンダ（８）により対地面対して略平行姿勢で昇降する昇降リンク機構部（９）に作物の先端部を切断処理する作業用カッター（１０）を駆動可能に装備してあることを特徴とする作業車両としたものである。 In order to solve the above problems, the present invention has taken the following technical means.
That is, the present invention described in claim 1 is attached to the front part of the traveling vehicle body (1), and the tip of the crop is attached to the lifting link mechanism part (9) that moves up and down in a substantially parallel posture with respect to the ground by the lifting cylinder (8). The working vehicle is characterized in that a working cutter (10) for cutting the portion is equipped to be drivable.

自走しながら圃場の作物に対して左右に往復動する作業用カッター（１０）が作用し、作物の先端部が適宜の位置で切断処理される。昇降シリンダ（８）の操作で昇降リンク機構（９）を上下に昇降することによって作物先端部の切断位置を任意に変更調節することができる。この場合、昇降リンク機構（９）は、対地面に対して略平行姿勢を保って昇降するため、カッターの作用角は略一定に保持することができ、切断処理が確実に行える。   A working cutter (10) that reciprocates left and right with respect to the crop in the field while self-propelled acts, and the tip of the crop is cut at an appropriate position. The cutting position of the crop tip can be arbitrarily changed and adjusted by moving the lifting link mechanism (9) up and down by operating the lifting cylinder (8). In this case, since the lifting link mechanism (9) moves up and down while maintaining a substantially parallel posture with respect to the ground, the working angle of the cutter can be held substantially constant, and the cutting process can be performed reliably.

請求項２記載の本発明は、前記昇降リンク機構部（９）には、圃場の作物に薬液を散布する散布ノズル（１３）を装備した散布ブームランス（１５）からなる薬液散布装置（１６）を前記作業用カッター（１０）の後方に備えてあることを特徴とする請求項１記載の作業車両としたものである。   The present invention according to claim 2 is directed to a chemical spraying device (16) comprising a spraying boom lance (15) equipped with a spray nozzle (13) for spraying chemicals to crops in a field on the lifting link mechanism (9). Is provided at the rear of the working cutter (10).

作物先端部の摘心作業を行いながら、作物に対する薬液散布が同時に行える。摘心作業と防除（薬液散布）作業の複合作業が行えるので作業効率が大幅に向上するものとなる。
請求項３記載の本発明は、前記作業用カッター（１０）及び散布ノズル（１３）は、水平基準線（Ｈ）より上下角度（α）の回動範囲をもつて角度調整可能に構成したことを特徴とする請求項２記載の作業車両としたものである。 It is possible to spray chemicals on the crop at the same time as the tip of the crop is being pinched. Since the combined operation of the pinching operation and the prevention (chemical solution spraying) operation can be performed, the work efficiency is greatly improved.
The invention according to claim 3 is configured such that the working cutter (10) and the spray nozzle (13) can be adjusted in angle with a rotation range of a vertical angle (α) from the horizontal reference line (H). A work vehicle according to claim 2, characterized in that:

作物の状況に応じて作業用カッター（１０）の角度を変えて作業を行うことで、作業効率が向上するものとなる。   Working efficiency is improved by changing the angle of the working cutter (10) according to the state of the crop.

以上要するに、請求項１の本発明によれば、作物に対する摘心作業を能率よく行うことができ、摘心作業用カッターの対地高さを自由に変更調節することができるので、適正な摘心位置にて作物先端部を切断することができる。また、上下に平行移動する昇降リンク機構を採用することによって別の作業装置の装着が容易にできる。   In short, according to the first aspect of the present invention, the pinching operation for the crop can be efficiently performed, and the height of the pinching operation cutter can be freely changed and adjusted. The crop tip can be cut. In addition, by adopting an elevating link mechanism that translates vertically, it is possible to easily attach another work device.

請求項２の本発明によれば、請求項１の発明効果を奏するものでありながら、摘心作業と防除作業の複合作業が同時に行え、作業効率が大幅に向上するものとなった。
請求項３の本発明によれば、請求項２の発明効果を奏するものでありながら、作物の状況に応じて作業用カッターの角度を変えることで、効率良く摘心作業が可能となる。 According to the second aspect of the present invention, while having the effect of the first aspect, the combined operation of the pinching operation and the control operation can be performed at the same time, and the work efficiency is greatly improved.
According to the third aspect of the present invention, while having the effect of the second aspect, the pinching operation can be efficiently performed by changing the angle of the working cutter in accordance with the state of the crop.

この発明の実施例を図面に基づいて説明する。
図１及び図２は、乗用作業車両示すものであり、この車体１の前部にエンジンＥを搭載し、このエンジンＥの回転動力を走行ミッションケ−ス２内の変速装置に伝え、この変速装置で減速された回転動力を前輪３と後輪４とに伝えるようにしている。機体後部側中央に運転席５が、その前方にはステアリングハンドル６が装備されている。 An embodiment of the present invention will be described with reference to the drawings.
1 and 2 show a passenger work vehicle. An engine E is mounted on the front portion of the vehicle body 1, and the rotational power of the engine E is transmitted to a transmission in the traveling mission case 2 so as to change the speed. The rotational power decelerated by the device is transmitted to the front wheel 3 and the rear wheel 4. A driver's seat 5 is provided in the center of the rear side of the fuselage, and a steering handle 6 is provided in front of it.

車体１の前方側には、昇降シリンダ８の伸縮作動により対地面対して略平行姿勢を保って昇降する昇降リンク機構９が装備されている。昇降リンク機構９には、作物の先端部を切断処理するバリカン式の摘心作業用カッター１０が油圧モータ１１によって駆動可能に装備されている。   On the front side of the vehicle body 1, an elevating link mechanism 9 that elevates and lowers while maintaining a substantially parallel posture with respect to the ground by an expansion and contraction operation of the elevating cylinder 8 is provided. The lifting / lowering link mechanism 9 is equipped with a clipper-type centripetal cutter 10 for cutting the tip of the crop so as to be driven by a hydraulic motor 11.

また、前記昇降リンク機構９部には、圃場の作物に薬液を散布する散布ノズル１３、散布ホース１４、散布ブームランス１５等を有した薬液散布装置１６が備えられている。機体後部に搭載された薬液タンク１８内の薬液は、ポンプにより散布ホ−ス１４を通じて散布ノズル１３から噴出されるようになっている。   The lifting link mechanism 9 includes a chemical spraying device 16 having a spray nozzle 13, a spray hose 14, a spray boom lance 15 and the like for spraying a chemical on crops in a field. The chemical solution in the chemical solution tank 18 mounted on the rear part of the machine body is ejected from the spray nozzle 13 through the spray hose 14 by a pump.

前記昇降リンク機構９は、回動軸芯Ｑ１，Ｑ２を支点として上下動する上リンク９ｕと下リンク９ｄと前リンク（フレーム）９ｆ等からなる。
摘心作業用カッター１０は、図３にも示すように、固定受刃１０ａと左右に往復動する可動刈刃１０ｂとからなり、そして、可動刈刃１０ｂは、偏心軸１２を有した油圧モータ１１にて駆動する構成であり、可動刈刃１０ａと一体化したＵ型プレート１０ｃに前記偏心軸１２を係合させた構成としている。カッターを駆動する油圧モータ１１の配置は、散布ブームランス１５の左右いずれか一方側端部に設置することで、カッターの駆動構成が上記のように簡潔となる。 The elevating link mechanism 9 includes an upper link 9u, a lower link 9d, a front link (frame) 9f, and the like that move up and down with pivot axes Q1 and Q2 serving as fulcrums.
As shown in FIG. 3, the centering cutter 10 includes a fixed receiving blade 10 a and a movable cutting blade 10 b that reciprocates left and right. The movable cutting blade 10 b includes a hydraulic motor 11 having an eccentric shaft 12. The eccentric shaft 12 is engaged with a U-shaped plate 10c integrated with the movable cutting blade 10a. The arrangement of the hydraulic motor 11 for driving the cutter is installed at either the left or right end of the spreading boom lance 15, so that the cutter drive configuration is simplified as described above.

また、かかる実施例では、油圧モータ１１への油圧ホース１７は、ブーム水平シリンダ１９への油圧ホース２０を付け替えて使用できるように共通化した構成としている。これによると、摘心装置専用の油圧ギヤポンプや油圧ホース等油圧配管する必要がなく、合理的で低コストの構成とすることができる。なお、油圧モータへの油圧ホースの取り付けは、ワンタッチカプラ１７ａ方式とし、ワンタッチで着脱できる構成としている。   In this embodiment, the hydraulic hose 17 to the hydraulic motor 11 is configured in common so that the hydraulic hose 20 to the boom horizontal cylinder 19 can be replaced and used. According to this, it is not necessary to provide hydraulic piping such as a hydraulic gear pump or a hydraulic hose dedicated to the centering device, and a rational and low-cost configuration can be achieved. Note that the hydraulic hose is attached to the hydraulic motor using a one-touch coupler 17a system, which can be attached and detached with one touch.

また、カッター１０の左右刈取幅は機体幅（前後輪の左右幅）より両外側方へ広くすることによって作物の摘心作業残しがなくなり、作業能率が向上する。なお、カッター１０の刈刃面は、機体進行方向と略直交する横方向に設けることで、作物の刈刃への入り込みが良くなり、切断精度が向上する。   Further, by making the right and left trimming width of the cutter 10 wider than the body width (left and right widths of the front and rear wheels), there is no crop leftover work and the work efficiency is improved. In addition, the cutting blade surface of the cutter 10 is provided in a lateral direction substantially orthogonal to the machine body traveling direction, so that the crop enters the cutting blade and the cutting accuracy is improved.

カッター１０の固定受刃１０ａは、散布ブームランス１５の前側で支持ステー２２を介して装着支持するように構成することで、カッターの支持構成が簡単で容易にでき部品点数も少なくなるメリットがある。カッター１０の支持高さは、運転席に着座するオペレータよりカッターの刃先が見える位置に配置しておくと、作物先端部の摘心位置が決め易くなる。   Since the fixed receiving blade 10a of the cutter 10 is configured to be mounted and supported via the support stay 22 on the front side of the spreading boom lance 15, there is an advantage that the support structure of the cutter is simple and easy and the number of parts can be reduced. . If the support height of the cutter 10 is arranged at a position where the blade edge of the cutter can be seen by an operator sitting on the driver's seat, the pinching position of the crop tip portion can be easily determined.

散布ノズル１３を有した散布ブームランス１５と一体的に設けた作物の摘心作業用カッター１０において、散布ブームランス１５の後方近くに左右方向に横たわる横軸２３を架設し、摘心作業用カッター１０と散布ブームランス１５が一体的に横軸２３を支点として回動できる構成としている。   In the cropping operation cutter 10 provided integrally with the application boom lance 15 having the application nozzle 13, a horizontal shaft 23 lying in the left-right direction is installed near the rear of the application boom lance 15, The spreading boom lance 15 is configured to be rotatable about the horizontal shaft 23 as a fulcrum.

これにより、カッター１０の作物に対する作用角度（進入角度）θ（図４）を任意に決定でき、最も切断性能が良好な切断角度を決定することができる。また、薬液の散布作業時においても噴霧角を任意に決定でき、作物の内部まで薬液が進入でき、よりよい防除効果を得ることができる。   Thereby, the working angle (entrance angle) θ (FIG. 4) of the cutter 10 with respect to the crop can be arbitrarily determined, and the cutting angle with the best cutting performance can be determined. Further, the spray angle can be arbitrarily determined even during the spraying operation of the chemical solution, the chemical solution can enter the crop, and a better control effect can be obtained.

また、カッター１０及び散布ノズル１３は、水平基準線Ｈより上下αの回動範囲をもつて角度調整できる構成としている。例えば、大豆の摘心作業を行う場合には、カッターがやや前方下向きとなるように角度設定し、散布作業を行う際には、散布ノズルがやや斜め前方下向きとなるように角度設定することで、両作業とも最適な角度設定が行えるようにしている。   In addition, the cutter 10 and the spray nozzle 13 are configured such that the angle can be adjusted with a rotation range of up and down α from the horizontal reference line H. For example, when performing soybean pinching work, the angle is set so that the cutter is slightly forward downward, and when performing the spraying work, the angle is set so that the spray nozzle is slightly diagonally downward downward, In both operations, the optimum angle can be set.

カッター１０の角度調節は、カッター位置より上方に配した調節ハンドル２４の回動操作で、伸縮可能なアジャスタ２５を介して行えるように構成してあり、そして、この調節ハンドル２４は、カッターの先端より前方に突出しない位置に配置することによって、ハンドル操作時に手がカッター先端に当たらないようにしている。   The angle of the cutter 10 can be adjusted via a retractable adjuster 25 by a turning operation of the adjustment handle 24 disposed above the cutter position. By arranging it at a position that does not protrude further forward, the hand does not hit the cutter tip during handle operation.

また、調節ハンドル２４及びアジャスタ２５は、カッター位置より上方に配置することによって調節時に作物との干渉がなくなり、ハンドル操作が容易に行える。
なお、摘心作業用カッターの角度調節手段の別実施例として、図５に示すように、縦フレーム（リンク）９ｆに装着されたブーム支持フレーム２１と、該フレーム２１から前方に突設する左右の連結部材２６，２６を介して連結支持される散布ブームランス１５との間に、カッターと散布ブームランスの回動支点である横軸２３を設けた構成のものにおいて、散布ブームランス１５とブーム支持フレーム２１との間を油圧シリンダ２７で連結し、運転席近くに設ける遠隔操作スイッチの操作で油圧シリンダ２７を伸縮作動させ、カッターの角度調節を遠隔操作できるように構成することもできる。 Further, the adjustment handle 24 and the adjuster 25 are arranged above the cutter position so that there is no interference with the crop during adjustment, and the handle operation can be easily performed.
As another embodiment of the angle adjusting means of the centering cutter, as shown in FIG. 5, a boom support frame 21 mounted on a vertical frame (link) 9f and left and right projections protruding from the frame 21 are provided. In a configuration in which a horizontal shaft 23 that is a pivot fulcrum of the cutter and the spreading boom lance is provided between the spreading boom lance 15 connected and supported via the connecting members 26 and 26, the spreading boom lance 15 and the boom support are provided. It is also possible to connect the frame 21 with a hydraulic cylinder 27 and to extend and retract the hydraulic cylinder 27 by operating a remote operation switch provided near the driver's seat so that the angle adjustment of the cutter can be remotely operated.

カッター１０及び散布ノズル１３の角度調節において、作物の摘心作業時には、カッター１０を図５に示すようにやや前方下向きに角度設定し、作物への散布作業時には、散布ノズル１３を図６に示すようにやや斜め前方下向きに角度設定する。かかる角度調節は前記油圧シリンダ２７による油圧操作にて遠隔操作することができる。   In adjusting the angles of the cutter 10 and the spray nozzle 13, the angle of the cutter 10 is set slightly forward and downward as shown in FIG. 5 during the cropping operation of the crop, and the spray nozzle 13 is shown in FIG. 6 during the spraying operation of the crop. Set the angle slightly diagonally forward and downward. Such angle adjustment can be remotely operated by hydraulic operation by the hydraulic cylinder 27.

次に、図７に示す実施例について説明する。
図示の構成は、前方側に散布ノズル１３を有した散布ブームランス１５の後方に摘心作業用カッター１０を配置した構成としている。大豆の摘心作業時に、散布ブームランス１５で作物の茎葉部を進行方向前方に向けて傾斜させ、散布ブームランスの下面を通過後、茎葉部の戻り力（跳ね返り力）を利用して刃先への食い込みを良くし、切断性能を高めるようにしている。 Next, the embodiment shown in FIG. 7 will be described.
The configuration shown in the drawing is configured such that a tipping cutter 10 is disposed behind a spray boom lance 15 having a spray nozzle 13 on the front side. At the time of picking soybeans, the stalks and leaves of the crop are tilted forward in the direction of travel with the spray boom lance 15, and after passing through the lower surface of the spray boom lance, the return force (bounce force) of the stalks and leaves is used to return to the cutting edge. The bite is improved and the cutting performance is improved.

また、上記構成において、散布ブームランスとカッターとの高さ方向の距離を変更できるように、散布ブームランス１５又はブーム支持フレーム２１に対してカッター１０を上下調節できるように構成しておくと、茎葉部の跳ね返り力を生かした最適な切断位置を決定することができる。   In the above configuration, if the cutter 10 can be adjusted up and down with respect to the spreading boom lance 15 or the boom support frame 21 so that the distance in the height direction between the spreading boom lance and the cutter can be changed, The optimum cutting position can be determined by making use of the rebound force of the foliage.

このような構成の散布ブームランスとカッターを上下に平行移動する昇降リンク機構９部に設置することで、昇降リンクの昇降によりブームランスでの茎葉部の押す位置を決めることができ、カッターの上下調節機能により常に適正位置を切断することが可能となる。   By installing the sprinkling boom lance and cutter having such a configuration in the lifting link mechanism 9 part that moves up and down in parallel, the position at which the foliage is pushed by the boom lance can be determined by raising and lowering the lifting link. The adjustment function can always cut the appropriate position.

図８に示す実施例では、昇降リンク機構９の前面に設けた前フレーム９ｆに、ブーム支持フレーム２１をローリング軸３０を介して左右ローリング自在に装着し、ブーム支持フレーム２１と前フレーム９ｆを自動水平シリンダ３１にて連結し、そして、このローリング可能なブーム支持フレーム２１に散布ブームランス１５と摘心作業用カッター１０を装備した構成としている。ブーム支持フレームは、機体が傾いても水平状態を保持するので、作物の摘心位置が正確に決まり、所定位置で確実に摘心することができる。   In the embodiment shown in FIG. 8, a boom support frame 21 is mounted on a front frame 9f provided on the front surface of the lift link mechanism 9 so as to be freely rollable left and right via a rolling shaft 30, and the boom support frame 21 and the front frame 9f are automatically mounted. The boom support frame 21 is connected to the horizontal cylinder 31 and is equipped with a spreading boom lance 15 and a pinching work cutter 10. Since the boom support frame maintains a horizontal state even when the machine body is tilted, the pinching position of the crop is accurately determined, and pinching can be reliably performed at a predetermined position.

また、変形例として、スロープ（傾斜）センサ３２は、カッター部を除くブーム支持フレーム２１又は散布ブームランス１５上面に設けておくと、機体の傾きに対して、その都度オペレータがカッターのローリング角度を修正しなくても良いので、操作性が向上する。   As a modification, if the slope (tilt) sensor 32 is provided on the upper surface of the boom support frame 21 or the spreading boom lance 15 excluding the cutter part, the operator can adjust the rolling angle of the cutter each time the machine body tilts. Since it does not need to be corrected, operability is improved.

なお、上記スロープセンサ３２は、角速度センサと一体化した構成とし、制御の優先順序として、より応答性の高い角速度センサを優先させ、機体傾斜による角速度を検出し、刈刃の自動水平性能を高めるようにしている。   The slope sensor 32 is integrated with the angular velocity sensor. As a priority order of control, the angular velocity sensor with higher response is prioritized, the angular velocity due to the tilt of the machine is detected, and the automatic horizontal performance of the cutting blade is enhanced. I am doing so.
