Description

本発明は、トラクタ等の作業車両に装着するロータリ耕耘装置等の作業機を、作業車両から取り外した状態で移動可能になす台車に関するものである。   The present invention relates to a carriage that can move a work implement such as a rotary tiller mounted on a work vehicle such as a tractor while being detached from the work vehicle.

トラクタで行う作業には普通耕耘作業や代掻き作業等があり、作業内容によってトラクタに装着する作業機をロータリ耕耘装置やドライブハロー等に取り替えて作業が行われる。また、取り外した作業機はそのまま放置しておくと邪魔になるので、倉庫内や納屋等の保管場所まで移動させる必要がある。
そこで、作業機の移動のために作業機毎にキャスタ付きのスタンドを取り付けることが行われており、トラクタから作業機を取り外す場合には、トラクタの昇降装置によって作業機を上昇させた状態で作業機にスタンドを取り付け、或いは非作用姿勢のスタンドを作用姿勢に反転させた後、作業機を下降させて作業機をスタンドに載置するようにしている。
一方、キャスタ付きのスタンドは作業機に合わせて専用のスタンドが用意され、そのためスタンドの購入費用が掛かるので、作業機の種類やメーカーに関係なく汎用的に作業機を載置可能なスタンドの発明もなされている（例えば、特許文献１参照）。 The work performed by the tractor includes a normal tillage work, a plowing work, and the like. Depending on the work content, the work machine mounted on the tractor is replaced with a rotary tiller, a drive harrow, or the like. In addition, since the removed working machine is disturbed if it is left as it is, it must be moved to a storage location such as a warehouse or a barn.
Therefore, a stand with a caster is attached to each work machine to move the work machine. When removing the work machine from the tractor, the work machine is lifted by the tractor lifting device. After the stand is attached to the machine or the stand in the non-working posture is reversed to the working posture, the work machine is lowered and the work machine is placed on the stand.
On the other hand, a stand with casters is provided with a dedicated stand according to the work machine, so it costs the purchase of the stand, so the invention of a stand on which the work machine can be mounted universally regardless of the type or manufacturer of the work machine (See, for example, Patent Document 1).

特開２０００−８３４０９号公報JP 2000-83409 A

前述のごとく、作業機を載置して移動可能なスタンドは費用面から勘案して、作業機の種類やメーカーに関係なく汎用的に用いることができるスタンドが望ましい。しかし、特許文献１に記載されたスタンドにあっては、従来のスタンドと同様にトラクタの昇降装置によって作業機を上昇させた状態でスタンドを取り付けた後、作業機を下降させて作業機をスタンドに載置しなければならない。
そのため、既にトラクタから取り外されて定置されている作業機をスタンドに改めて載置すること、逆にスタンドに載置された作業機を降ろしてその場に定置することは、作業機が相当な重量物であることから困難である。また、汎用的に使用できるスタンドといっても、一旦、作業機を載置したスタンドは作業機を降ろさない限り、その作業機専用のスタンドとなり、別の作業機を移動させる必要があったとしても、そのスタンドを使用して作業機を移動させることができないという問題がある。
そこで、本発明は、係る問題点に鑑みて、トラクタから取り外されて定置されている作業機を保管場所まで移動させることができると共に、保管場所まで移動させた作業機をその場に定置することができ、さらに別の作業機の移動手段としてそのまま使用することができる、汎用的な作業機移動用の台車を提供することを目的とする。 As described above, the stand on which the work machine can be placed and moved can be used universally regardless of the type and manufacturer of the work machine, considering the cost. However, in the stand described in Patent Document 1, after the work machine is lifted by the tractor lifting device in the same manner as the conventional stand, the work machine is lowered and the work machine is lowered. Must be placed on.
For this reason, it is necessary to place a work machine that has already been removed from the tractor and place it on the stand, and on the contrary, to lower the work machine placed on the stand and place it on the spot. It is difficult because it is a thing. Also, even if it is a stand that can be used for general purposes, once the stand on which the work implement is placed becomes a stand dedicated to that work implement unless it is lowered, it is necessary to move another work implement However, there is a problem that the work machine cannot be moved using the stand.
Therefore, in view of such problems, the present invention is capable of moving a work implement that has been removed from a tractor and placed to a storage location, and placing the work implement moved to a storage location on the spot. Another object of the present invention is to provide a general-purpose carriage for moving a work machine that can be used as it is as a moving means for another work machine.

上記課題を解決するための本発明の第１の技術的手段は、キャスタを備えた作業機の台車は、作業機の上部と下部とを支承する支持部を備え、当該支持部を定置された作業機の上部と下部に宛がい、台車と共に作業機を傾倒すると、作業機は台車上に浮上して、支持部に支承されるように構成することを特徴とする。
また、第２の技術的手段は、作業機の上部と下部とを支承する支持部を、作業機の上部連結ピンを支承する上部支持部と耕耘爪軸を支承する下部支持部とで構成することを特徴とする。
さらに、第３、第４、及び第５の技術的手段は、作業機の上部を支承する高さを調節自在に構成すること、作業機の下部を支承する高さを調節自在に構成すること、並びに作業機の下部を支承する位置を左右方向に調節自在に構成することを特徴とする。 A first technical means of the present invention for solving the above-described problem is that a cart of a work machine provided with a caster includes a support part that supports an upper part and a lower part of the work machine, and the support part is stationary. The work machine is configured to reach the upper part and the lower part of the work machine, and when the work machine is tilted together with the carriage, the work machine floats on the carriage and is supported by the support portion.
In addition, the second technical means comprises a support part for supporting the upper and lower parts of the work implement by an upper support part for supporting the upper connection pin of the work implement and a lower support part for supporting the tilling claw shaft. It is characterized by that.
Further, the third, fourth, and fifth technical means are configured such that the height for supporting the upper portion of the work implement is adjustable, and the height for supporting the lower portion of the work implement is adjustable. And the position which supports the lower part of a working machine is comprised so that adjustment is possible in the left-right direction.

本発明のキャスタを備えた作業機の台車によれば、作業機の上部と下部とを支承する支持部を備え、当該支持部を定置された作業機の上部と下部に宛がい、台車と共に作業機を傾倒すると、作業機は台車上に浮上して、支持部に支承されるように構成するので、作業車両から取り外されて定置されている作業機を、台車上に簡単に載置して保管場所まで移動させることができる。また、保管場所まで移動させた作業機を台車から簡単に降ろして、その場に定置することができるので、台車を別の作業機の移動手段として使い回すことができ、費用対効果を上げることができる。
また、作業機の上部と下部とを支承する支持部を、作業機の上部連結ピンを支承する上部支持部と耕耘爪軸を支承する下部支持部とで構成すると、作業機側に台車に載置するための部品等を新たに追加する必要が無く、余分な費用や部品の取付け作業を強いることがない。
さらに、作業機の上部を支承する高さを調節自在に構成し、また、作業機の下部を支承する高さを調節自在に構成し、或いは作業機の下部を支承する位置を左右方向に調節自在に構成すると、台車に載置することができる作業機の適合性を増すことができると共に、台車に作業機を適切な姿勢で載置して不測な転倒等を防止しながら、作業機を円滑に移動することができる。 According to the cart of the working machine provided with the caster of the present invention, the working machine is provided with a support part for supporting the upper part and the lower part of the work machine, the support part is addressed to the upper part and the lower part of the stationary work machine, When the machine is tilted, the work machine floats on the carriage and is supported by the support part, so the work machine that has been removed from the work vehicle and placed in place can be easily placed on the carriage. It can be moved to a storage location. In addition, since the work equipment moved to the storage location can be easily lowered from the cart and placed on the spot, the cart can be reused as a means of moving another work equipment, increasing cost effectiveness. Can do.
In addition, if the support part for supporting the upper and lower parts of the work implement is composed of an upper support part for supporting the upper connection pin of the work implement and a lower support part for supporting the tilling claw shaft, it is mounted on the cart on the work implement side. There is no need to add new parts or the like for installation, and there is no need for extra costs or installation of parts.
In addition, the height to support the upper part of the work implement is adjustable, the height to support the lower part of the work implement is adjustable, or the position to support the lower part of the work implement is adjusted in the left-right direction If it is configured freely, the compatibility of the work machine that can be placed on the cart can be increased, and the work machine can be mounted on the cart in an appropriate posture to prevent unexpected fall and the like.

以下、本発明の実施の形態を図面に基づいて説明する。図１乃至図３に示すように、作業機の台車１はフレーム部Ａ、キャスタ部Ｂ、下部支持部Ｃ、及び上部支持部Ｄから構成している。
その内、台車１の骨格を形成するフレーム部Ａは、角パイプによって構成する縦枠フレーム２，２に横枠フレーム３，３の端部を接合して溶接し、また、縦枠フレーム２，２の後部上面に丸パイプで構成するハンドル４の脚部を溶接し、そして、縦枠フレーム２，２の中間部とハンドル４の脚部の中途部に補強フレーム５，５の端部を接合して溶接し、さらに、ハンドル４の脚部の中途部どうしに亘って補強プレート６を溶接し、台車１のフレームを構成している。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1 to FIG. 3, the cart 1 of the work machine includes a frame part A, a caster part B, a lower support part C, and an upper support part D.
Among them, the frame portion A that forms the skeleton of the carriage 1 is welded by joining the end portions of the horizontal frame frames 3 and 3 to the vertical frame frames 2 and 2 constituted by square pipes, and welding. 2 welds the leg of the handle 4 made of a round pipe to the upper surface of the rear part, and joins the ends of the reinforcing frames 5 and 5 to the middle of the vertical frame 2 and 2 and the middle of the leg of the handle 4 Further, the reinforcing plate 6 is welded between the middle portions of the leg portions of the handle 4 to constitute the frame of the carriage 1.

また、キャスタ部Ｂは、縦枠フレーム２，２の前部及び後部の下面に取り付けた前キャスタ（前輪）７，７と後キャスタ（後輪）８，８から構成し、前・後キャスタ７，８は全てを方向転換可能なものにするか、何れか一方を方向転換可能なものにするか、何れも方向転換はしないものに構成することができる。   The caster part B includes front casters (front wheels) 7 and 7 and rear casters (rear wheels) 8 and 8 attached to the lower surfaces of the front and rear parts of the vertical frame frames 2 and 2. , 8 can be configured so that all of them can change direction, or one of them can change direction, neither of which can change direction.

さらに、下部支持部Ｃは、図４に示すように上部側内周に雌螺子部９ａを形成する支持筒９と、下部側外周に雄螺子部１０ａを形成するロッド１０によって構成している。また、支持筒９は下部に角パイプから構成するボス１１を備え、ボス１１は前側の横枠フレーム３に外嵌しており、これにより下部支持部Ｃは、前後回動不能、且つ左右方向に位置調節自在となっている。さらに、ロッド１０の雄螺子部１０ａは支持筒９の雌螺子部９ａに螺合し、ロッド１０を支持筒９に対して相対的に回動するとロッド１０は伸縮して、ロッド１０の上部に一体的に形成した受部１０ｂの高さを調節することができる。   Further, as shown in FIG. 4, the lower support portion C includes a support cylinder 9 that forms a female screw portion 9 a on the upper inner periphery and a rod 10 that forms a male screw portion 10 a on the lower outer periphery. The support cylinder 9 is provided with a boss 11 formed of a square pipe at the lower portion, and the boss 11 is externally fitted to the front horizontal frame 3 so that the lower support portion C cannot be rotated back and forth and is laterally movable. The position is adjustable. Further, the male screw portion 10a of the rod 10 is screwed into the female screw portion 9a of the support cylinder 9, and when the rod 10 is rotated relative to the support cylinder 9, the rod 10 expands and contracts, The height of the integrally formed receiving portion 10b can be adjusted.

そして、上部支持部Ｄは、図５に示すように上向きのフック１２によって構成している。このフック１２は補強プレート６にボルト１３とナット１４とワッシャ１５で取り付けられ、ボルト１３は補強プレート６に穿設した上下方向の長孔６ａ内に挿入される。従って、ナット１４の端部に溶接した丸棒で構成するグリップ１６を握ってナット１４を緩め、次にボルト１３位置を調節して、再びナット１４を締め付けると、フック１２の取付け高さを上下方向に調節することができる。   And the upper support part D is comprised by the upward hook 12 as shown in FIG. The hook 12 is attached to the reinforcing plate 6 with a bolt 13, a nut 14, and a washer 15, and the bolt 13 is inserted into a vertical hole 6 a formed in the reinforcing plate 6. Therefore, when the nut 16 is loosened by grasping the grip 16 composed of a round bar welded to the end of the nut 14, and then the bolt 13 position is adjusted and the nut 14 is tightened again, the mounting height of the hook 12 is increased or decreased. Can be adjusted to the direction.

次に、台車１に載置する作業機の一例としてロータリ耕耘装置１７の構成を説明する。図６乃至図８に示すようにロータリ耕耘装置１７は、図示しないトラクタの後部に備えられる三点リンク機構のトップリンクとロアーリンクに連結されて圃場の耕耘作業を行う。
ロータリ耕耘装置１７は、トラクタ側よりＰＴＯ動力が入力されるギヤケース１８を備え、ギヤケース１８には左右一対のプレートからなるトップマスト１９が取り付けられている。また、トップマスト１９の前方上部にはトップリンクに結合する上部連結ピン２０が設けられている。 Next, a configuration of the rotary tiller 17 will be described as an example of a working machine placed on the carriage 1. As shown in FIGS. 6 to 8, the rotary tiller 17 is connected to a top link and a lower link of a three-point link mechanism provided at a rear portion of a tractor (not shown) to perform a tilling operation on the field.
The rotary tiller 17 includes a gear case 18 to which PTO power is input from the tractor side, and a top mast 19 including a pair of left and right plates is attached to the gear case 18. Further, an upper connecting pin 20 that is coupled to the top link is provided at an upper front portion of the top mast 19.

さらに、ロータリ耕耘装置１７のギヤケース１８の左右にはパイプフレーム２１が取り付けられている。また、左側のパイプフレーム２１の外端部にはチェーンケース２２が取り付けられ、右側のパイプフレーム２１の外端部にはサイドフレーム２３が取り付けられている。さらに、チェンケース２２の下端側とサイドフレーム２３の下端側との間に耕耘爪軸２４が回転駆動自在に軸支され、耕耘爪軸２４には耕耘爪２５が複数取り付けられている。そして、耕耘爪２５の上方、後方、及び側方はメインカバー２６とリヤカバー２７とサイドカバー２８とによって覆われている。   Further, pipe frames 21 are attached to the left and right of the gear case 18 of the rotary tiller 17. A chain case 22 is attached to the outer end of the left pipe frame 21, and a side frame 23 is attached to the outer end of the right pipe frame 21. Further, a tilling claw shaft 24 is rotatably supported between the lower end side of the chain case 22 and the lower end side of the side frame 23, and a plurality of tilling claws 25 are attached to the tilling claw shaft 24. The upper, rear and side portions of the tilling claw 25 are covered with a main cover 26, a rear cover 27 and a side cover 28.

上記リヤカバー２７は前端がメインカバー２６側に回動自在に軸支され、また、加圧ロッド２９によって吊支されている。ここで、ロータリ耕耘装置１７をトラクタから取り外してその場に定置する場合には、予め加圧ロッド２９の上下動を固定してリヤカバー２７の回動を不能にしておく。その後、ロータリ耕耘装置１７の耕耘爪２５が接地するまで下降させて、トラクタからロータリ耕耘装置１７を取り外すと、ロータリ耕耘装置１７は図６に示すように耕耘爪２５とリヤカバー２７の下端が接地した起立姿勢で保持される。   The front end of the rear cover 27 is pivotally supported on the main cover 26 side, and is suspended by a pressure rod 29. Here, when the rotary tiller 17 is removed from the tractor and placed on the spot, the vertical movement of the pressure rod 29 is fixed in advance to make the rear cover 27 unrotatable. Thereafter, the tiller 25 of the rotary tiller 17 is lowered until it contacts the ground, and when the rotary tiller 17 is removed from the tractor, the rotary tiller 17 is grounded at the lower ends of the tiller 25 and the rear cover 27 as shown in FIG. Hold in a standing position.

次に、台車１の使用方法を説明すると、先ず定置されたロータリ耕耘装置１７を台車１に載置する場合には、定置されたロータリ耕耘装置１７の前部側に台車１の正面側を向けて、前キャスタ７，７を支点としてハンドル４を持ち上げ、台車１を前傾させる。そして、台車１の前傾姿勢においてフック１２がトップマスト１９の上部連結ピン２０に係合するようにフック１２を上部連結ピン２０に引っ掛ける。この状態でハンドル４を押し下げると、ロータリ耕耘装置１７は前方に徐々に傾倒していく。さらに、ロータリ耕耘装置１７が前方に傾倒していくと、ロッド１０の上部に設けた受部１０ｂが耕耘爪軸２４に宛がわれ、これ以降はロータリ耕耘装置１７が地上から浮上して持ち上げられ、最終的に図７に示すように、台車１上にロータリ耕耘装置１７がフック１２と受部１０ｂによって支承されて載置された状態になる。   Next, a method of using the carriage 1 will be described. When the fixed rotary tiller 17 is first placed on the carriage 1, the front side of the carriage 1 is directed to the front side of the fixed rotary tiller 17. The handle 4 is lifted with the front casters 7 and 7 as fulcrums, and the carriage 1 is tilted forward. Then, the hook 12 is hooked on the upper connecting pin 20 so that the hook 12 engages with the upper connecting pin 20 of the top mast 19 in the forward inclined posture of the carriage 1. When the handle 4 is pushed down in this state, the rotary tiller 17 gradually tilts forward. Further, when the rotary tiller 17 is tilted forward, the receiving portion 10b provided on the upper portion of the rod 10 is directed to the tillage claw shaft 24, and thereafter, the rotary tiller 17 is lifted and lifted from the ground. Finally, as shown in FIG. 7, the rotary tiller 17 is supported and placed by the hook 12 and the receiving portion 10 b on the carriage 1.

従って、作業機１７を台車１上に載置するには、台車１の上部支持部Ｄを構成するフック１２と下部支持部Ｃを構成するロッド１０の受部１０ｂを、作業機１７の上部に設けた上部連結ピン２０と下部に設けた耕耘爪軸２４に宛がい、台車１と共に作業機１７を前方に傾倒すると、作業機１７は台車１上に浮上して、上部支持部Ｄと下部支持部Ｃに支承された載置姿勢となる。これによって、ハンドル４を押すと前・後キャスタ７，８が転がり、作業機１７を保管場所まで移動することができる。   Therefore, in order to place the work machine 17 on the carriage 1, the hook 12 constituting the upper support part D of the carriage 1 and the receiving part 10 b of the rod 10 constituting the lower support part C are placed on the upper part of the work machine 17. When the working machine 17 is tilted forward together with the carriage 1 when it is directed to the upper connecting pin 20 provided and the tilling claw shaft 24 provided at the lower part, the working machine 17 floats on the carriage 1 and supports the upper support D and the lower support. The mounting posture is supported by the part C. Accordingly, when the handle 4 is pushed, the front and rear casters 7 and 8 roll, and the work machine 17 can be moved to the storage location.

また、作業機１７を保管場所に定置する場合には、上記と逆の手順を踏むことになる。その際に、ハンドル４を持ち上げると先ず耕耘爪２５が接地し、さらに持ち上げるとリヤカバー２７の下端が接地した当初の作業機１７の起立姿勢になる。その段階で台車１の上部支持部Ｄのフック１２と下部支持部Ｃの受部１０ｂが作業機１７から外れ、ここで台車１を作業機１７の前方に後退されれば、作業機１７を単独で定置することができる。また、その後は、台車１を別の作業機の移動用の台車として使用することができる。一方、定置された作業機１７は起立姿勢となり、台車１が取り外されていることから、作業機１７の保管スペースは作業機１７自体で足りることになる。   Further, when the work machine 17 is placed at the storage location, the reverse procedure is performed. At this time, when the handle 4 is lifted, the tilling claws 25 are grounded first, and when the handle 4 is further lifted, the lower end of the rear cover 27 is grounded to the original working machine 17 standing posture. At that stage, if the hook 12 of the upper support D and the receiving portion 10b of the lower support C of the carriage 1 are detached from the work implement 17 and the carriage 1 is retracted to the front of the work implement 17 at this stage, the work implement 17 is separated. Can be fixed. After that, the carriage 1 can be used as a carriage for moving another work machine. On the other hand, since the stationary work machine 17 is in the standing posture and the carriage 1 is removed, the work machine 17 itself needs a storage space for the work machine 17.

なお、作業機１７を台車１上に載置する際には、予め作業機１７が適切な姿勢に載置されるように、台車１側で上部支持部Ｄと下部支持部Ｃの位置を調節しておくことが好ましい。
即ち、ロータリ耕耘装置１７を作業機とした場合には、耕耘爪２５が最下端となるので、耕耘爪軸２４を支持する下部支持部Ｃの受部１０ｂの高さをロッド１０の回動によって、少なくともロータリ耕耘装置１７を台車１上に載置した状態で、耕耘爪２５が地上より浮上する高さに調節する。 When the work implement 17 is placed on the carriage 1, the positions of the upper support portion D and the lower support portion C are adjusted on the cart 1 side in advance so that the work implement 17 is placed in an appropriate posture. It is preferable to keep it.
That is, when the rotary tiller 17 is used as a working machine, the tilling claw 25 is the lowermost end, so that the height of the receiving part 10b of the lower support part C that supports the tilling claw shaft 24 is adjusted by the rotation of the rod 10. Then, at least the rotary tiller 17 is placed on the carriage 1, and the height of the tillage claw 25 is adjusted to rise from the ground.

次に、左右の受部１０ｂ，１０ｂが共に耕耘爪２５・・と干渉せず、また、耕耘爪軸２４に密着するように、受部１０ｂの左右方向の位置をボス１１の左右移動によって調節する。
さらに、上部支持部Ｄを構成するフック１２の上下位置調節は、上部連結ピン２０と耕耘爪軸２４間の長さによって決まり、予め調節しておくこともできるが、作業機１７を台車１上に載置する前に予めナット１４を緩めておき、次に、耕耘爪軸２４に下部支持部Ｃの受部１０ｂを宛がった状態で、フック１２を上部連結ピン２０に係合する位置まで引き上げて、その位置でナット１４を締め付けて固定することができる。 Next, the horizontal position of the receiving portion 10b is adjusted by the left and right movement of the boss 11 so that the left and right receiving portions 10b and 10b do not interfere with the tilling claw 25. To do.
Further, the vertical position adjustment of the hook 12 constituting the upper support portion D is determined by the length between the upper connecting pin 20 and the tilling claw shaft 24 and can be adjusted in advance. The nut 14 is loosened in advance before being placed on the hook, and then the hook 12 is engaged with the upper connecting pin 20 in a state where the receiving portion 10b of the lower support portion C is applied to the tilling claw shaft 24. The nut 14 can be tightened and fixed at that position.

尚、前述の実施例においては、作業機としてロータリ耕耘装置１７を例に採り取り上げたが、作業機としては、ロータリ耕耘装置の構成と比較的近似するドライブハローであっても良く、或いは畦塗機等の他の作業機であっても良い。
また、上部支持部Ｄは、トラクタに連結される作業機として通常備える上部連結ピン２０をフック１２で支承するように構成したが、上部連結ピン２０に限らず作業機の上部側に存在する部材を対象として、これを支承するように構成しても良い。
同様に下部支持部Ｃは、トラクタに連結される作業機として通常備えるロアリンク取り付け用の下部連結ピンを支承するように構成しても良い。 In the above-described embodiments, the rotary tiller 17 is taken as an example of the working machine. However, the working machine may be a drive harrow that is relatively similar to the configuration of the rotary tiller, or a coater. Other working machines may be used.
Moreover, although the upper support part D was comprised so that the upper connection pin 20 normally equipped as a working machine connected with a tractor might be supported by the hook 12, it is not only the upper connection pin 20, but the member which exists in the upper part side of a working machine. You may comprise so that this may be supported.
Similarly, the lower support C may be configured to support a lower connection pin for attaching a lower link, which is normally provided as a work machine connected to the tractor.
