本発明は、作物の草丈の高さを揃える剪定機に関する。   The present invention relates to a pruning machine that aligns the heights of crop plants.

特許文献１には、大豆の草丈の高さを揃える走行車両型の剪定機について開示されている。   Patent Document 1 discloses a traveling vehicle type pruning machine that matches the height of soybean plant height.

特許第４３４０８４４号公報Japanese Patent No. 4340844

特許文献１の走行車両型の剪定機は刈刃が走行車両の左右幅内のため剪定能率が低かった。本発明は剪定能率を向上させる。   The pruning machine of the traveling vehicle type of Patent Document 1 has a low pruning efficiency because the cutting blade is within the lateral width of the traveling vehicle. The present invention improves pruning efficiency.

本発明はかかる技術的課題を解決するために次のような技術的手段を講じる。
走行車両の前側に横長姿勢の左右一対の刈刃を設け、
剪定作業姿勢時は、左右の刈刃を同一直線状に配置し、走行車両の左右幅より外側まで延びる構成とし、
走行姿勢時には、一方の刈刃を横軸心回りに上方に回動して非作業姿勢とすると共に、他方の刈刃を剪定可能な姿勢で、スライド機構により左右それぞれの刈刃を左右内側にスライドして刈刃が上下方向に重なる構成とすることを特徴とする走行車両型の作物剪定機とする。 The present invention takes the following technical means in order to solve such technical problems.
Provide a pair of left and right cutting blades in the landscape orientation on the front side of the traveling vehicle,
At the time of pruning work posture, the left and right cutting blades are arranged in a straight line, and are configured to extend to the outside from the left and right width of the traveling vehicle,
During the running posture, one cutting blade is rotated upward about the horizontal axis to make it a non-working posture, and the other cutting blade can be pruned, and the left and right cutting blades are moved inwardly by the slide mechanism. It is set as the traveling vehicle type crop pruning machine characterized by making it the structure which slides and a cutting blade overlaps with an up-down direction .

これにより、走行車両幅以上の作物の剪定を一度に行えるため、剪定作業能率が良い。   As a result, crops that are greater than the width of the traveling vehicle can be pruned at a time, so pruning efficiency is high.

また、走行するときには刈刃を走行車両の左右幅内側にスライドさせることで安全に走行できる。 Moreover, it can be safely run is slid to the left and right width within the side of the traveling vehicle cutting blade when running.

また、刈刃を合理的に走行位置に収納できる。 Further, the cutting blade can be rationally stored in the traveling position.

It is set as the structure supported by. The link mechanism 6 can be moved up and down with a cylinder or the like (not shown), and the cutting blade unit K is moved up and down together with the link mechanism 6.

刈刃ユニットＫは平面視で左右方向に横長姿勢のバリカン型の刈刃１０（１０ａ，１０ｂ）と、左右端部に設ける送風機１１（１１ａ，１１ｂ）と、送風機１１の下方に刈刃１０を駆動するギア等の駆動機構を収容した駆動機構ボックス１２（１２ａ，１２ｂ）と、送風機１１及び刈刃１０を駆動する刈刃エンジン１３（１３ａ，１３ｂ）を備える。また、刈刃ユニットＫは刈刃１０の前側かつ上方にあって刈刃と並行した姿勢に設けるガイド体１４（１４ａ，１４ｂ）を設け、刈刃１０の後側には刈刃１０で剪定した作物を内側に案内する案内板１５（１５ａ，１５ｂ）を設けている。案内板１５は左右外側から内側に向かって斜め後ろ姿勢に設けている。   The cutting blade unit K has a clipper-type cutting blade 10 (10a, 10b) that is horizontally long in the left-right direction in plan view, a blower 11 (11a, 11b) provided at the left and right ends, and a cutting blade 10 below the blower 11. A drive mechanism box 12 (12a, 12b) containing a drive mechanism such as a gear to drive, and a cutting blade engine 13 (13a, 13b) for driving the blower 11 and the cutting blade 10 are provided. Further, the cutting blade unit K is provided with a guide body 14 (14a, 14b) provided in a posture parallel to the cutting blade in front of and above the cutting blade 10, and pruned by the cutting blade 10 on the rear side of the cutting blade 10. Guide plates 15 (15a, 15b) for guiding the crops inward are provided. The guide plate 15 is provided in an obliquely rearward posture from the left and right outer sides to the inner side.

刈刃ユニットＫは左右一対に設け、左右それぞれの刈刃１０を同一直線上に略水平姿勢に設け、それぞれの内端を接近して対向し、それぞれの外端を走行車両Ｔの左右外側まで延びる構成とし、さらに刈刃の左右両外端の外側にそれぞれ刈刃エンジン１３、送風機１１、駆動機構ボックス１２を配置する構成である。送風機１１は送風口ｓ（ｓ１，ｓ２）をそれぞれ刈刃１０の外端の上方に配置し、かつ内側に向かって送風するよう設けている。   The cutting blade units K are provided in a pair of left and right, the left and right cutting blades 10 are provided in a substantially horizontal posture on the same straight line, the inner ends approach each other and face each other, and the outer ends extend to the left and right outer sides of the traveling vehicle T. Further, the cutting blade engine 13, the blower 11, and the drive mechanism box 12 are arranged outside the left and right outer ends of the cutting blade. The blower 11 is provided so that the blower ports s (s1, s2) are respectively arranged above the outer end of the cutting blade 10 and blown toward the inside.

刈刃ユニットＫはそれぞれ左右方向にスライド可能に構成している。具体的には支持アーム７に固定姿勢で取付けるスライド受けアーム２０（２０ａ，２０ｂ）と、スライド受けアーム２０に対して左右方向にスライドするスライドアーム２１（２１ａ，２１ｂ）を設け、スライドアーム２１側に刈刃１０、送風機１１、駆動機構ボックス１２、刈刃エンジン１３、ガイド体１４、案内板１５を支持し、スライドアーム２１のスライド動作に伴い、共に刈刃ユニットＫとして一体的にスライドする構成である。   The cutting blade units K are configured to be slidable in the left-right direction. Specifically, a slide receiving arm 20 (20a, 20b) that is attached to the support arm 7 in a fixed posture and a slide arm 21 (21a, 21b) that slides in the left-right direction with respect to the slide receiving arm 20 are provided. The blade 10, the blower 11, the drive mechanism box 12, the blade engine 13, the guide body 14, and the guide plate 15 are supported, and the slide blade 21 is slid integrally as a slide blade 21 as the slide arm 21 slides. It is.

スライド受けアーム２０には一対の燃料タンク２２（２２ａ，２２ｂ）を取付けている。
剪定作業について説明する。 A pair of fuel tanks 22 (22a, 22b) are attached to the slide receiving arm 20.
The pruning operation will be described.

刈刃１０を走行車両Ｔの外側まで延びる状態とし、走行前に左右それぞれの刈刃エンジン１３を始動（本実施の形態では左右それぞれリコイルスタータ式）すると、刈刃１０が駆動を開始する。そして、オペレータは、運転座席５に着座し、リンク機構昇降レバー２３を操作して刈刃１０の切断位置Ｅを所望の高さ位置に設定して走行車両Ｔを圃場で走行させる。圃場は畝Ｕに作物Ｍを植えており、走行車輪１は畝Ｕ間を走行し、走行車輪１の内側の畝Ｕと外側の畝Ｕの作物Ｍにわたって一度に作物の上部Ｍ１を切断して草丈を揃える剪定作業を行う。   When the cutting blade 10 is extended to the outside of the traveling vehicle T and the left and right cutting blade engines 13 are started before traveling (in this embodiment, the left and right recoil starter type), the cutting blade 10 starts to drive. Then, the operator sits on the driver's seat 5, operates the link mechanism elevating lever 23, sets the cutting position E of the cutting blade 10 to a desired height position, and causes the traveling vehicle T to travel in the field. In the field, crops M are planted on the ridges U, the traveling wheels 1 travel between the ridges U, and the upper M1 of the crops are cut at once across the ridges U on the inner side of the traveling wheels 1 and the crops M on the outer ridges U. Pruning work to align the plant height.

切断された作物Ｍの上部Ｍ１は、送風機１１の送風口ｓ１からの送風で内側に向かって吹き飛ばされ、かつ案内板１５に案内されて内側に寄せられて圃場に落下する。そのため、剪定され切断された作物の草が刈刃１０に絡みつくのを防止している。また、切断された草を集中的に案内できるため、作業後に集めやすくすることができる。   The upper part M1 of the cut crop M is blown inward by the air blown from the blower port s1 of the blower 11, and is guided by the guide plate 15 to the inside and falls to the farm field. Therefore, the crop grass that has been pruned and cut is prevented from being entangled with the cutting blade 10. Moreover, since the cut grass can be intensively guided, it can be easily collected after work.

次に、路上を走行したり、走行車輪１内の畝だけを剪定作業する場合について説明する。
一方の刈刃ユニットＫ１を回動軸２５によって横軸芯周りに上方に回動させる。 Next, a description will be given of a case where the vehicle travels on the road or the pruning operation is performed only on the basket in the traveling wheel 1.
One cutting blade unit K1 is rotated upward about the horizontal axis by the rotation shaft 25.

すると、刈刃１０ａが上向きになる（図５参照）。
そして、その状態の姿勢で内側に向かってスライドさせると共に、他方の刈刃ユニットＫ２をそのままの姿勢で内側に向かってスライドさせる。すると、二つの刈刃ユニット（Ｋ１，Ｋ２）が上下方向に重なり合い、かつ、いずれの刈刃ユニット（Ｋ１，Ｋ２）も走行車両の左右幅の範囲内に略入る（図４参照）。 Then, the cutting blade 10a faces upward (see FIG. 5).
Then, while sliding inward in the posture in that state, the other cutting blade unit K2 is slid inward in the same posture. Then, the two cutting blade units (K1, K2) overlap in the vertical direction, and any of the cutting blade units (K1, K2) substantially falls within the lateral width of the traveling vehicle (see FIG. 4).

そのため、路上等の走行時に刈刃１０が走行車両の左右外側に出ないので、人や障害物に当たることを防止し、安全に走行することができる。
刈刃ユニットＫをスライドするときにはロックハンドル２６（２６ａ，２６ｂ）を操作することでロック解除及びロックをでき構成としている。ロックハンドル２６は複数個所に適宜設けている。 Therefore, since the cutting blade 10 does not come out on the left and right outside of the traveling vehicle during traveling on the road or the like, it can be prevented from hitting a person or an obstacle and can travel safely.
When the cutting blade unit K is slid, the lock handle 26 (26a, 26b) is operated so that the lock can be released and locked. The lock handle 26 is appropriately provided at a plurality of locations.

この走行時の姿勢で、刈刃１０ｂを水平姿勢に保っている側（すなわち切断作業姿勢）の刈刃ユニットＫ２側の刈刃エンジン１３を始動し、走行することで走行車輪１の内側の畝Ｕの作物Ｍの剪定作業を行うことができる。このとき、刈刃１０ａを上側に向けた側（すなわち非切断作業姿勢）の刈刃ユニットＫ１は切断作業姿勢の刈刃ユニットＫ２の上方に位置する構成とすることで、非切断作業姿勢の刈刃ユニットＫ１が作物に絡むことを防止することができる。また、圃場の隣接地に塀等の障害物等が存在する場合に、刈刃１０を走行車両Ｔの左右幅の範囲内で剪定作業をすることで、刈刃が人や障害物に当接せず安全な剪定作業を行える。   In this running posture, the cutting blade engine 13 on the side of the cutting blade unit K2 on the side where the cutting blade 10b is maintained in a horizontal posture (that is, the cutting work posture) is started and traveled so that Pruning of U crop M can be performed. At this time, the cutting blade unit K1 with the cutting blade 10a facing upward (that is, the non-cutting working posture) is positioned above the cutting blade unit K2 in the cutting working posture, so that the cutting blade in the non-cutting working posture can be obtained. It is possible to prevent the blade unit K1 from being entangled with the crop. In addition, when an obstacle such as a hoe is present adjacent to the field, the cutting blade abuts against a person or an obstacle by pruning the cutting blade 10 within the lateral width of the traveling vehicle T. Safe pruning work can be done without.

図８は一方の刈刃１０の姿勢を内側に向かって後ろ斜め姿勢に変更したことを示している。この刈刃の姿勢を変更するにはボルト２７（２７ａ，２７ｂ）を緩めると長孔２８（２８ａ，２８ｂ）に沿って案内板１５ａと刈刃１０ａの角度が変更する。そして姿勢を変更したほうの刈刃ユニットＫ１を少しだけ内側にスライド（矢印）すると、姿勢を変更した側の刈刃１０ａの内端が他方の刈刃１０ｂの内端の後方に位置することが可能となる。   FIG. 8 shows that the posture of one of the cutting blades 10 is changed to an obliquely backward posture toward the inside. To change the posture of the cutting blade, when the bolt 27 (27a, 27b) is loosened, the angle between the guide plate 15a and the cutting blade 10a is changed along the long hole 28 (28a, 28b). When the cutting blade unit K1 whose posture has been changed is slid slightly inward (arrow), the inner end of the cutting blade 10a on the side whose posture has been changed may be positioned behind the inner end of the other cutting blade 10b. It becomes possible.

これは、剪定作業時に左右の刈刃１０の隙間Ｂを無くして作業を行いたいと考えている作業者のためである。   This is for an operator who wishes to perform the work without the gap B between the left and right cutting blades 10 during the pruning work.

本実施の形態の作物は主として大豆であるが、圃場の草丈を均一に剪定したい作物ならば適用できる。   The crop of this embodiment is mainly soybean, but can be applied to crops that want to uniformly prun the plant height in the field.
