Description

本発明は、歩行型動力運搬車に関し、特には、スイッチバック機能を備えた歩行型動力運搬車に関するものである。   The present invention relates to a walking power vehicle, and more particularly to a walking power vehicle having a switchback function.

歩行作業者が機体の後側に付いて走行操作を行う歩行型動力運搬車は、特に農作業用として広く普及しており、果樹園等での収穫物運搬作業等に用いられている。   A walking type power transport vehicle in which a walking worker attaches to the rear side of the aircraft and performs a traveling operation is widely used especially for agricultural work, and is used for harvesting work in orchards and the like.

中山間のカンキツ園は、傾斜地に立地していることが多く、高品質な果実生産が可能な反面、平坦地に比べて労働条件は不利である。とりわけ石積み階段園をはじめとする急傾斜園地は、日当たりや排水が良好で、優良・有名な産地を形成しているものの、今後も後継者を確保し、産地を維持・発展させていくためには農作業労働の軽減を図ることが必須の課題である。とくに収穫した果実の運搬作業では、傾斜がきつく、テラス幅の狭い石積み階段園で利用できる機械がなく、簡易な手押し式台車による人力運搬か、直接コンテナをかかえての運搬をせざるを得ないのが現状であり、極めて重労働となっている。このため、クローラ式の動力運搬車など、機械による労働の改善が求められている。   The citrus orchards between the mountains are often located on sloping land, and high-quality fruit production is possible, but the working conditions are disadvantageous compared to flat land. In particular, steep slopes such as masonry staircases have good sunlight and drainage, and form excellent and famous production areas. In order to secure successors and maintain and develop production areas in the future. It is an essential task to reduce agricultural labor. Especially for transporting harvested fruits, there is no machine that can be used in a stone staircase with a narrow slope and a narrow terrace, and it must be transported by hand using a simple hand-drawn cart or directly with a container. The current situation is extremely hard work. For this reason, improvement of labor by machines such as crawler type power vehicles is demanded.

このような作業条件では乗用型の運搬車は安全性とコストの面で採用できない場合が多く、果樹園等での運搬作業には歩行型の動力運搬車が利用されている。歩行型動力運搬車の従来技術としては、下記の特許文献１，２等に記載のものが知られている。   Under such work conditions, a passenger-type transport vehicle cannot be adopted in terms of safety and cost in many cases, and a walk-type power transport vehicle is used for transport work in an orchard or the like. As a conventional technology of a walking type power transport vehicle, those described in Patent Documents 1 and 2 below are known.

特開２００６−２２４７７３号公報JP 2006-224773 A 実開平５−４４６９７号公報Japanese Utility Model Publication No. 5-44697

果樹園の運搬作業にこれまで利用されていたクローラ式の動力運搬車は、一般に、クローラ幅（車体幅）が60〜65cm、車体の長さが1.7m程度の大きさの運搬車で、20kgコンテナを6個（3個×2段積み）程度搭載して運搬走行するものである。これによると、幅80〜100cmの通路があれば走行可能で、運搬作業の労働軽減に大きな効果があることから、主に園内作業道が整備された傾斜25度までの果樹園地で利用されている。   A crawler-type power transport vehicle that has been used for orchard transport is generally a transporter with a crawler width (vehicle width) of 60 to 65 cm and a vehicle length of about 1.7 m. It carries about 6 containers (3 x 2 stacks). According to this, it is possible to travel if there is a passage with a width of 80 to 100 cm, and it has a great effect on labor reduction of transportation work, so it is mainly used in orchards up to 25 degrees tilt where the work path in the park is maintained Yes.

しかしながら、テラス状に整備された急傾斜石積み階段園（傾斜25度〜45度）において上述の運搬車を利用しようとするとき、走行空間の確保が困難であることから、実際の農作業には使用されていないのが現状である。すなわち、階段園の狭いテラス内で、例えば幅1m程度の通路を確保し、直線走行・運搬ができたとしても、運搬車の旋回（Uターン）を行うためには、走行通路よりもさらに広い幅2m程度の空間が必要となる。   However, because it is difficult to secure a traveling space when using the above-mentioned transport vehicle in a steep stone masonry staircase (gradient 25 to 45 degrees) arranged in a terrace shape, it is used for actual farm work. The current situation is not. In other words, in a narrow terrace of the staircase, for example, even if a passage of about 1 m in width is secured, and the vehicle can run and transport in a straight line, it is even wider than the traveling passage to turn the transport vehicle (U-turn). A space of about 2m in width is required.

このため、テラスの中でも旋回できる地点が限られ、コンテナを積み込みたい任意の場所で旋回をすることができず、空間が広い場所まで無駄に走って旋回をしなければならない問題がある。また、広い空間といえども、幅2〜2.5mのテラス内で全長1.7mの運搬車を旋回させるには、空間的余裕がほとんどなく、作業者は運搬車の誤操作を行わないように緊張を強いられ、操作時の安全性も懸念される。   For this reason, there are only a limited number of places on the terrace where the turn is possible, and it is not possible to turn at any place where the container is to be loaded. Also, even in a wide space, there is almost no room for turning a transport vehicle with a total length of 1.7m in a terrace with a width of 2 to 2.5m, and the operator is nervous so as not to misoperate the transport vehicle. There is a concern about safety during operation.

狭いスペースで車両を旋回させる他の方法としては、油圧ショベルのようにクローラ部分は動かさずに、車両の上半分だけが360度水平に旋回できる機構がある。しかし、既存のクローラ運搬車にこの機構を搭載したとしても、旋回中には車体長さである1.7m幅の空間が必要であるため、運搬車のすぐ側にある石積みに荷台が当たったり、または木の枝に車体が引っかかったりして、容易に旋回できないことは明らかである。   As another method of turning the vehicle in a narrow space, there is a mechanism in which only the upper half of the vehicle can turn 360 degrees horizontally without moving the crawler part like a hydraulic excavator. However, even if this mechanism is installed in an existing crawler truck, a space of 1.7m width, which is the length of the car body, is required during turning, so the loading platform hits the masonry on the immediate side of the truck, Or it is obvious that the car body is caught on a tree branch and cannot be turned easily.

本発明は、このような問題に対処するために提案されたものであって、走行空間の狭い石積み階段果樹園等において、運搬作業の軽労働化を図るため、旋回動作が不要な歩行型動力運搬車を提供することを目的とするものである。   The present invention has been proposed in order to cope with such problems, and in a stone stairs orchard or the like where the traveling space is narrow, a walking type power that does not require a turning motion in order to reduce the labor of transportation work. The purpose is to provide a transport vehicle.

このような目的を達成するために、本発明は、一つには、歩行型動力運搬車において、荷台と、該荷台の下方に配備される駆動部によって駆動される走行部と、前記荷台及び前記走行部を支持する機体と、該機体の進行方向に沿った切り替え操作によって前記走行部を前進又は後進駆動させる操作盤と、該操作盤を前記機体の進行方向に対する前後方向の一端側から他端側に移動させる操作盤移動機構と、前記機体の進行方向に対する前後方向の一端側に設けられ、該一端側に前記操作盤が移動している場合に該操作盤が固定可能となる第１の操作盤支持部と、前記機体の進行方向に対する前後方向の他端側に設けられ、該他端側に前記操作盤が移動している場合に該操作盤が固定可能となる第２の操作盤支持部と、を備え、操作盤の位置は、機体の進行方向に対する前後方向の機体長の範囲内に常に位置することを特徴とする。 In order to achieve such an object, in one aspect, the present invention provides, in a walking power vehicle, a loading platform, a traveling unit driven by a driving unit disposed below the loading platform, the loading platform, An aircraft that supports the traveling unit, an operation panel that drives the traveling unit forward or backward by a switching operation along the traveling direction of the aircraft, and the operation panel that is moved from one end side in the front-rear direction to the traveling direction of the aircraft. An operation panel moving mechanism that moves to the end side, and a first that is provided on one end side in the front-rear direction with respect to the traveling direction of the machine body and that can be fixed when the operation panel is moved to the one end side. And a second operation that can be fixed when the operation panel is moved to the other end side. It includes a board supporting portion, the operation panel position Wherein always be located within the front-rear direction of the vehicle body length to the traveling direction of the aircraft.

また一つには、前記操作盤移動機構は、前記操作盤を支持して前記機体の幅方向に跨る門型フレームを備え、該門型フレームの端部を前記機体の前後中心位置に回動自在に軸支した回動フレームによって前記機体の進行方向に対する前後方向の一端側から他端側に移動可能であり、前記操作盤移動機構が、前記機体の進行方向に対する前後方向の一端側から他端側に移動する際に、前記回動フレームに対して前記門型フレームが屈曲した状態で移動することによって、前記荷台に積荷された荷物の近傍を移動可能であることを特徴とする。 In another aspect, the operation panel moving mechanism includes a portal frame that supports the operation panel and spans the width direction of the machine body, and the end of the portal frame is rotated to the front-rear center position of the machine body. It is movable from one end side in the front-rear direction with respect to the traveling direction of the machine body to the other end side by a pivot frame that is freely supported , and the operation panel moving mechanism is moved from one end side in the front-rear direction with respect to the traveling direction of the machine body. When moving to the end side, it is possible to move in the vicinity of the load loaded on the loading platform by moving the portal frame in a bent state with respect to the rotating frame .

また一つには、前述した歩行型動力運搬車において、前記操作盤移動機構は、前記機体の前後中心位置に回動自在に軸支され前記操作盤を前記機体の進行方向に対する前後方向の一端側から他端側に移動させる平行リンクを備えることを特徴とする。
Further, in the above-described walking-type power transport vehicle, the operation panel moving mechanism is pivotally supported at a center position in the front-rear direction of the machine body and is pivotally supported at one end in the front-rear direction with respect to the traveling direction of the machine body. characterized in that it comprises a parallel link to move from side to another end side.

このような特徴を有する本発明の歩行型動力運搬車によると、歩行型動力運搬車の進行方向を１８０度切り替える場合には、操作盤移動機構によって操作盤を機体の進行方向一方端側から他方端側に移動させ、歩行作業者が機体の進行方向一方端側から他方端側に移動することで、旋回操作を行うことなく進行方向を１８０度変更することができる。   According to the walking type power transport vehicle of the present invention having such a feature, when the traveling direction of the walking type power transport vehicle is switched by 180 degrees, the operation panel is moved from one end side to the other side by the operation panel moving mechanism. By moving to the end side and the walking worker moving from one end side to the other end side in the advancing direction of the aircraft, the advancing direction can be changed by 180 degrees without performing a turning operation.

この際に、操作盤は、機体の進行方向に沿った切り替え操作によって走行部を前進又は後進駆動させることができるものであり、また、操作盤移動機構はこの操作盤を平行移動するものであるから、進行方向を１８０度変更した場合にも前進方向へ向けた切り替え操作で機体を前進させることができることになり、誤操作を起こすことなく作業を継続することができる。   At this time, the operation panel can drive the traveling part forward or backward by a switching operation along the advancing direction of the machine body, and the operation panel moving mechanism moves the operation panel in parallel. Therefore, even when the traveling direction is changed by 180 degrees, the aircraft can be advanced by the switching operation in the forward direction, and the operation can be continued without causing an erroneous operation.

これによって、旋回を行うための空間がない狭い通路であっても、歩行型動力運搬車を簡易且つ安全に往復動させることができ、果樹園等での作業性を向上させることができる。   Thereby, even if it is a narrow passage with no space for turning, the walking power vehicle can be reciprocated easily and safely, and workability in an orchard or the like can be improved.

以下、本発明の実施形態を図面に基づいて説明する。図１は、本発明の実施形態に係る歩行型動力運搬車の全体構成を示す斜視図である。歩行型動力運搬車１は、荷台１０と、荷台１０の下方に配備される駆動部（図示省略）によって駆動される走行部１１と、荷台１０及び走行部１１を支持する機体１２と、機体１２の進行方向（矢印方向）前後両側にそれぞれ設けられる操作盤支持部１３Ａ，１３Ｂと、操作盤支持部１３Ａ又は１３Ｂに着脱自在に取り付けられ、機体１２の進行方向に沿った切り替え操作によって走行部１１を前進又は後進駆動させる操作盤１４と、操作盤１４を一方の操作盤支持部１３Ａから他方の操作盤支持部１３Ｂに平行移動させる操作盤移動機構２０と、を備える。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an overall configuration of a walking power vehicle according to an embodiment of the present invention. The walking type power transport vehicle 1 includes a loading platform 10, a traveling unit 11 driven by a driving unit (not shown) provided below the loading platform 10, a body 12 that supports the loading platform 10 and the traveling unit 11, and a body 12. The operation part 11 is attached to the operation panel support parts 13A and 13B and the operation panel support part 13A or 13B, which are respectively provided in the front and rear sides (in the direction of the arrows). And an operation panel moving mechanism 20 that translates the operation panel 14 from one operation panel support part 13A to the other operation panel support part 13B.

また、必要に応じて、荷台１０には、荷物の脱落防止用のフレーム１５が設けられ、機体１２の進行方向前後端には、歩行作業者用のハンドル部１６Ａ，１６Ｂが設けられている。   Further, if necessary, the loading platform 10 is provided with a frame 15 for preventing the luggage from dropping off, and handle parts 16A and 16B for walking workers are provided at the front and rear ends of the machine body 12 in the traveling direction.

走行部１１は、ここではクローラ１１Ａを備えるものを示しているが、これに限らずホイール式のものでもよい。駆動部は、操作盤１４の切り替え操作によって駆動制御できるものであればよく、電動式の場合には、モータ及びバッテリによって構成することができ、操作盤１４からは図示省略のケーブルが駆動部に接続されることになる。また、操作盤１４から無線信号で駆動を操作するものであってもよい。   Here, the traveling unit 11 includes a crawler 11A. However, the traveling unit 11 is not limited thereto, and may be a wheel type. The drive unit may be any drive unit that can be driven and controlled by switching operation of the operation panel 14. In the case of an electric type, the drive unit can be constituted by a motor and a battery. Will be connected. Further, the drive may be operated by a radio signal from the operation panel 14.

操作盤移動機構２０は、この実施形態では、操作盤１４を支持して機体１２の幅方向に跨る門型フレーム２０Ａを備え、門型フレーム２０Ａの端部を機体１２の前後中心位置に回動自在に軸支した回動フレーム２０Ｂによって一方の操作盤支持部１３Ａから他方の操作盤支持部１３Ｂに移動可能にしている。すなわち、回動フレーム２０Ｂは一端が機体１２の前後中心位置Ｐ1で軸支され、他端が門型フレーム２０Ａの端部Ｐ2で軸支されている。また、門型フレーム２０Ａは、固定部材２０Ｃによって操作盤支持部１３Ａ，１３Ｂに着脱自在に固定されている。 In this embodiment, the operation panel moving mechanism 20 includes a portal frame 20A that supports the operation panel 14 and straddles the width direction of the machine body 12, and the end of the portal frame 20A is rotated to the front-rear center position of the machine body 12. It is possible to move from one operation panel support section 13A to the other operation panel support section 13B by a pivoting frame 20B that is freely pivoted. That is, the pivoting frame 20B has one end pivotally supported at around the center position P 1 of the machine body 12, the other end is pivotally supported at the end P 2 of the portal frame 20A. The portal frame 20A is detachably fixed to the operation panel support portions 13A and 13B by a fixing member 20C.

図２及び図３は、前述した本発明の実施形態に係る歩行型動力運搬車１の機能を説明する説明図である。   2 and 3 are explanatory views for explaining the function of the walking type power transport vehicle 1 according to the above-described embodiment of the present invention.

図２において、歩行型動力運搬車１を矢印Ａ方向に移動させる場合には、歩行作業者Ｍは、ハンドル部１６Ａ側に位置して操作盤支持部１３Ａに固定された操作盤１４を操作することで、歩行型動力運搬車１を走行させる。   In FIG. 2, when the walking type power transport vehicle 1 is moved in the arrow A direction, the walking worker M operates the operation panel 14 that is located on the handle portion 16A side and is fixed to the operation panel support portion 13A. Thus, the walking type power transport vehicle 1 is caused to travel.

そして、進行方向を矢印Ｂ方向に切り替える際には、固定部材２０Ｃの固定を解除して操作盤移動機構２０を移動可能にし、前後中心位置Ｐ1を中心に回動フレーム２０Ｂを回動させながら、端部Ｐ2で軸支された門型フレーム２０Ａを立てた状態で、操作盤移動機構２０を移動させる。この際に、門型フレーム２０Ａを立てた状態で移動させることができるので、荷台１０にコンテナ等の荷物Ｃが高く積み上げられている場合にも、これを跨いで移動させることができる。 Then, when switching the direction of travel in the direction of arrow B releases the fixing of the fixing member 20C to allow moving the operation panel moving mechanism 20, while rotating the rotating frame 20B around the center position P 1 before and after in an upright state axially supported by the portal frame 20A at the end P 2, to move the operation panel moving mechanism 20. At this time, since the portal frame 20A can be moved in an upright state, even when a load C such as a container is piled up high on the loading platform 10, it can be moved across the same.

反対側の操作盤支持部１３Ｂに操作盤１４を移動させると、再び固定部材２０Ｃによって門型フレーム２０Ａ及び操作盤１４を操作盤支持部１３Ｂに固定し、ハンドル部１６Ｂ側に移動した歩行作業者Ｍによって操作盤１４を操作することで、歩行型動力運搬車１を矢印Ｂ方向に走行させる。   When the operation panel 14 is moved to the opposite operation panel support part 13B, the portal frame 20A and the operation panel 14 are again fixed to the operation panel support part 13B by the fixing member 20C, and the walking worker moved to the handle part 16B side. By operating the operation panel 14 with M, the walking power vehicle 1 is caused to travel in the direction of arrow B.

図３は、操作盤１４の切り替え操作方向と機体の進行方向の関係を示した説明図である。この実施形態では、左右のクローラをそれぞれ駆動操作するために操作盤１４には左右２つの操作レバー１４Ａ，１４Ｂが備えられている。この操作レバー１４Ａ，１４Ｂを同時に操作方向Ａに切り替え操作することで機体はその方向に沿った進行方向Ａに向けて走行し、その逆に、操作レバー１４Ａ，１４Ｂを同時に操作方向Ｂに切り替え操作することで機体はその方向に沿った進行方向Ｂに向けて走行するようになっている。これによると、操作盤１４が平行移動した後にも、機体の進行方向と操作レバーの切り替え操作方向は変わらないので、進行方向を変更した後にも誤操作なく機体を走行させることができる。   FIG. 3 is an explanatory diagram showing the relationship between the switching operation direction of the operation panel 14 and the traveling direction of the aircraft. In this embodiment, the operation panel 14 is provided with left and right operation levers 14A and 14B for driving the left and right crawlers. By switching the operation levers 14A and 14B in the operation direction A at the same time, the aircraft travels in the traveling direction A along that direction, and conversely, the operation levers 14A and 14B are simultaneously switched in the operation direction B. By doing so, the airframe travels in the traveling direction B along that direction. According to this, even after the operation panel 14 moves in parallel, the advancing direction of the airframe and the switching operation direction of the operation lever do not change, so that the airframe can be run without an erroneous operation even after the advancing direction is changed.

図４は、本発明の他の実施形態を示す説明図である（前述した実施形態と同一部分は同一符号を付して重複説明を省略する）。この実施形態では、操作盤移動機構２０は、機体１２の前後中心位置に回動自在に軸支され操作盤１４を一方の操作盤支持部１３Ａから他方の操作盤支持部１３Ｂに移動させる平行リンク２１を備えている。このような平行リンク２１によって操作盤１４を移動させることによって、方向を維持した状態で簡単に操作盤１４を移動させることができる。   FIG. 4 is an explanatory diagram showing another embodiment of the present invention (the same parts as those of the above-described embodiment are denoted by the same reference numerals and redundant description is omitted). In this embodiment, the operation panel moving mechanism 20 is pivotally supported at the front and rear center position of the machine body 12 so as to be rotatable, and moves the operation panel 14 from one operation panel support part 13A to the other operation panel support part 13B. 21 is provided. By moving the operation panel 14 with such parallel links 21, the operation panel 14 can be easily moved while maintaining the direction.

以上説明した本発明の実施形態によると、旋回動作なく機体を往復走行させることができる歩行型動力運搬車を提供することができるので、走行空間の狭い石積み階段果樹園等において、運搬作業の労力軽減を図ることができる。   According to the embodiment of the present invention described above, since it is possible to provide a walk-type power transport vehicle that can reciprocate the aircraft without a turning motion, the labor of transport work in a stone stairs orchard with a narrow travel space, etc. Mitigation can be achieved.
