Description

【0001】
【発明の属する技術分野】
本発明は、地雷を効率的に処理でき、合わせて農地改良で農耕地の確保をも可能となる地雷処理装置に関するものである。
【0002】
【従来の技術】
地雷の中で対人用の地雷の処理は、従来、全て手作業で行われている。詳しくは、まず、大抵長い棒体に固定した金属探知機に似た地雷探知機を使って一つずつ探知する。探知が出来たなら、水をまき、土を柔らかくした上で地雷の状況を確認する。刷毛等で土を除き地雷を見える状態にしてから火薬を仕掛けて誘爆させるものであり、このように従来の地雷の処理は、一つずつ専門的技術を持つ者の経験とカンに頼って処理を行っているので、多くの時間と労力を費やさざるを得ないことはいうまでもない。
【0003】
そこで、無限軌道車を利用してブルドーザタイプのものやショベルタイプのものを地雷掃討のために使用することにより、地雷掃討に伴う危険に曝されることなく、能率的に掃討を行なうことができることが種々提案されている。発明者も先に、図10に示すように、バックホウ等のショベル機で使用する重機車両1の起伏かつ屈折自在なアーム部2の先端に、バケットに代えて回転ドラム10の周面にカッタビット11を植設し、深さ30cm程度以上まで切削可能で、進行方向に対して反対側に排土可能なロータリーカッタ9を取り付けたこと地雷処理装置を発明し、第301608号、特許第3096847 号、第3177737 号を得た。

【0005】
図中、3は走行のための履帯であるが、このようなクローラ式のものの他に履帯の代わりに車輪を有するホイールタイプのものでもよい。
【0006】
起伏かつ屈折自在なアーム部2はブーム2a、アーム2b、ブームシリンダ2c、アームシリンダ2d、バケットシリンダ2eで構成され、その先端にはリンク機構5aの先にアタッチメント側のピン6の抱持間隔を可変とするネジハンドル式のスライド機構5bを組み込んだアタッチメント着脱装置5を設けた。このアタッチメント着脱装置5はアタッチメントのピン6を抜かずに組み替えできるものでクイックヒッチと称せられる。
【0007】
運転席3の窓ガラスにはポリカーボネイト板の特殊防弾ガラス7を採用し、さらに、その前面にはメッシュの鋼製網体によるガード8を設ける。
【0008】
ロータリーカッタ9はレーキ26を横側に突設し、また、背面側にフラップ式の飛散防止ブレード27を設ける。
【0009】
ロータリーカッタ9を回転させながら旋回、ブーム2aやアーム2bを作動させ、荒地に生えているブッシュ、草等も切削粉砕すると同時に、さらに地表面下に埋設されている対人地雷をも一気に粉砕処理することができる。特に、高速で回転するロータリーカッタ9は、深さ30cm程度まで切削可能なものなので、対人地雷が土中に埋もれていてもこれを掘り出し、カッタビット11が地雷に接触すると打撃された対人地雷は変形し、内部の火薬系列が破壊されるとともに、電気回路が切断される。
【0010】
次の歯(カッタビット11)で対人地雷はロータリーカッタ9中に巻き込まれ、ケースと蓋が分離して火薬類が粉々に飛散してしまう。
【0011】
このため、電気式信管の対人地雷はまったく爆発せず、一方、機械式信管の対人地雷では、信管のみが破裂するだけで、対人地雷本体が爆発することはない。処理された地雷は、ケース、蓋、電気回路基板に分かれて地上に排出され、進行方向に対して反対側に排土されるので、対人地雷の上に泥が被さりこれが埋まってしまうこともない。
【0012】
ところで、前記特許文献2の特開2000-130996 号公報(特許第3016018 号)では、地雷探査装置17をアーム部2の先端で横側に取付ける。地雷探査装置17は図示は省略するが運転席3内に設置する信号処理部及びモニタ用CRTに接続される。
【0013】
地雷探査装置17はジャッキ式の伸縮アームにより繰り出し可能なものであり、この地雷探査装置17をアーム部2の動きとジャッキ式の伸縮アームの動きで一定の条件で移動させ、地下1m以内にある埋設物を探知し、その材質、種類を識別できる。CRT上に材質、位置、深さを標示する。
【0014】
地雷探査装置17で対人地雷と対戦車地雷・不発弾とを区別し、対戦車地雷・不発弾の場合はロータリーカッタ9のレーキ26またはスケルトンバケットで露出させ、事後、人力等で爆発地点に運搬し処理し、対人地雷の場合はロータリーカッタ9の高速回転により破壊する。この地雷探査装置17は金属探知機または/およびレーザー探査機、もしくは超音波探査機等による。
【0015】
【発明が解決しようとする課題】
しかし、前記前記特許文献2では、地雷探査装置17は起伏かつ屈折自在なアーム部2のアーム2bの先端で横側に取付けられたもので、常にロータリーカッタ9の近くに位置し、ロータリーカッタ9の運転時で地雷探査を行わない場合でもアーム2bとともに移動するので移動量も多く不安定な状態に置かれ、ロータリーカッタ9での作業の邪魔になるおそれもある。
【0016】
また、対人地雷を破壊した後に散在する金属片、金属部品、金属球等がロータリーカッタ9に付着していると、これが地雷探査装置17に反応してしまうと、適切かつ迅速な地雷探査が行えないことになる。
【0017】
本発明の目的は前記従来例の不都合を解消し、バックホウ等のショベル機で使用する重機車両のブーム、アーム、ブームシリンダ、アームシリンダ、バケットシリンダで構成された起伏かつ屈折自在なアーム部の先端に、着脱自在にロータリーカッタを取り付ける地雷処理装置において、地雷探査装置をロータリーカッタの邪魔にならないように、安定した状態で設けることができ、確実に地雷探査を行うことができる地雷処理装置を提供することにある。
【0018】
【課題を解決するための手段】
本発明は前記目的を達成するため、起伏かつ屈折自在なアーム部のブームに地雷探査装置の支持アームを回動自在に設け、ロータリーカッタの非使用時にはこの支持アームが前記アームと交差するようにし、また、ロータリーカッタ使用時には支持アームをブームに沿わせるように収納すること、および、地雷探査装置の支持アームはブームに回動自在に設けた鞘管内に摺動する伸縮構造であり、鞘管の先端はフード状に拡径して地雷探査装置の収納部を形成することを要旨とするものである。
【0019】
請求項1記載の本発明によれば、地雷探査装置の支持アームは、起伏かつ屈折自在なアーム部のアームではなく、ブームに設けるものであり、アームの動きで動かされることはない。しかも、ロータリーカッタの非使用時にはアームはブーム対して鋭角になるように畳まれ、邪魔にならないようにするが、その際には、地雷探査装置の支持アームが前記アームと交差するようにして、十分前方に伸びる状態となり、ロータリーカッタと離れた状態で地雷探査を行うことができる。
【0020】
また、ロータリーカッタ使用時にはアームはブーム対して延設されるように伸びるが、地雷探査装置の支持アームをブームに沿わせるように収納することでこの地雷探査装置をロータリーカッタと離した状態で邪魔にならないようにすることができる。
【0021】
請求項2記載の本発明によれば、前記作用に加えて、地雷探査装置および支持アームは鞘管とその先端のフード状収納部に納まり、これらがケース体として非使用時の保護をなすとともに、鞘管は地雷探査装置を伸縮させるための部材構成の一部を負担し、少ない部材点数で合理的な機構となる。
【0022】
【発明の実施の形態】
以下、図面について本発明の実施の形態を詳細に説明する。図1は本発明の地雷処理装置の1実施形態を示す側面図で、前記従来例を示す図 と同一構成要素には同一参照符号を付したものである。
【0023】
本発明の地雷処理装置も現在市場で最も多用されているバックホー等のシャベル等で使用する重機車両(ベースマシン)1を使用するが、この重機車両1には起伏かつ屈折自在なアーム部2と排土板22とが設けられている。3は運転席(キャビン)、4は走行のための履帯であるが、このようなクローラ式のものの他に履帯の代わりに車輪を有するホイールタイプのものでもよい。履帯4では急な斜面等で威力を発揮するが、ホイールタイプの場合は平地での前(後)進力が増す。前記排土板22は防爆用ブレードであり、ブレードシリンダー22aを有する。
【0024】
起伏かつ屈折自在なアーム部2はブーム2a、アーム2b、ブームシリンダ2c、アームシリンダ2d、バケットシリンダ2eで構成され、その先端にはリンク機構5aの先にピン6で着脱できるアタッチメントとしてのロータリーカッタ9を設けた。
【0025】
ロータリーカッタ9は、回転ドラム10の周面にカッタホルダー13を溶接して設け、このカッタホルダー13を介して炭素鋼を材質とするカッタビット11を適宜間隔で植設した。
【0026】
さらに、ロータリーカッタ9は、バケット28aに対してシリンダ等でのグラップルリンク28cにより可動するグラップル28bを設けて挟み込み動作が可能なフォークグラップル付バケット28を横側に付設した。
【0027】
また、ロータリーカッタ9の反対側の側方には、電気式であり、バックホー等のシャベル等で使用する重機車両(ベースマシン)1の動力電源を操作スイッチで電源供給するマグネット14を設けた。
【0028】
図中17は地雷探査装置であるが、図5〜図7に示すように、矩形管である内管15aと外管15bの多重管による収縮可能な支持アーム15の内管15aの先端にチルトシリンダー16で120°程度回動自在に設ける。
【0029】
前記支持アーム15の外管15bは矩形管である鞘管18内に摺動自在に収め、この鞘管18の先端はフード状に拡径して地雷探査装置17の収納部19を形成した。20a、20bはこれら内管15aと外管15b、外管15bと鞘管18とを連結して伸縮させる伸縮シリンダーである。
【0030】
鞘管18は、前記起伏かつ屈折自在なアーム部2のブーム2aにその中央部分を軸着し、これらにセンサー用シリンダー21を掛け渡した。その結果、支持アーム15はブーム2aに回動自在に設けられる。
【0031】
次に使用法について説明する。図9は本発明の地雷処理装置の使用工程を示すブロック図であるが、地雷探査作業と探査した地雷の処理作業とに分かれ、さらに、処理作業は対人地雷、対戦車地雷、不発弾の場合とに分かれる。
【0032】
探査作業は、各種情報の事前調査結果から、地雷等があると予想される場所に地雷探査装置17を近づけて行うが、図1に示すようにロータリーカッタ9の非使用時であり、起伏かつ屈折自在なアーム部2はブーム2aに対してアーム2bは鋭角をなして折り畳まれ、ロータリーカッタ9は運転席3側に近づくように位置させる。
【0033】
一方、鞘管18を含めて地雷探査装置17の支持アーム15は前記アーム2bと交差するようにし、鞘管18から支持アーム15を伸ばして地雷探査装置17を地表に近づけて作業行を行う。
【0034】
地雷探査装置17での探査作業は、2段階に分けて行う。第1段階は、探知モードで作業する。センサー部底面を地上5〜10cmの一定高に保ち、旋回速度2km/h〜4km/hでブーム2aを旋回させて探知作業を行う。
【0035】
地中に地雷や不発弾を探知すると、音声による発見信号が発せられる。続いて、第2段階の精密モードに切り替え、正確な情報を探知する。地雷探査装置17を発見位置の前後に繰り返し走査し、埋設物の種類、正確な深さ、位置、材質の種別を明らかにし、CRTに映し出し、記録する。
【0036】
位置が確定したら、地雷探査装置17を地雷等の上に止め、図示は省略するが地雷探査装置17自体またはその近傍に組み込んだマーキングシステムで地上に標示塗料でマーキングを行う。
【0037】
探知作業により明らかになった対戦車地雷、不発弾は、事後のロータリーカッタによる対人地雷処理の安全確保のため、これを処理する。図4に示すようにフォークグラップル付バケット28のバケット28aを使用し、標示された位置の土中にある対戦車地雷、不発弾を爆発させないように慎重に掘り出し、必要に応じてグラップル28bで掴み、爆発処理地点に運搬し処理する。
【0038】
対人地雷の処理は、図2に示すように、探査作業により明らかになった対人地雷の位置を重点に、全ての地域をロータリーカッタ9により隈なくクリアリングし、対人地雷を処理する。処理作業は、ロータリーカッタ9のガイド底面を地表に接触させながら、旋回し、ロータリーカッタ9のカッタビットの刃先が地下30cmまで達するようにする。土地の固さや地面に凹凸に応じ、旋回速度を変化させたり、2段階作業により十分な深さを確保する。
【0039】
未処理部分の無いよう、探査作業と同様、5〜10cmをオーバーラップさせる。対人地雷は、ロータリーカッタ9の高速回転により、爆発することなく破壊され、破片が地上に放出される。種類によっては、信管のみが破裂することがあるが、装置に対する影響はない。
【0040】
このようなロータリーカッタ9やフォークグラップル付バケット28の使用の場合には支持アーム15を縮めて鞘管18内に収めるようにすれば、地雷探査装置17は収納部19内に収まる。
【0041】
さらに鞘管18を回動してこれに収納された支持アーム15をブーム2bに沿わせるようにして地雷探査装置17に収納すれば、作業の邪魔になることはない。
【0042】
前記作業により、対人地雷は30cmまで、対戦車地雷及び不発弾は1mまで処理される。さらに、安全確認のため、処理した全域にわたり、残った地雷等が無いかを地雷探査装置17によりチェックする。これにより、この地域の処理が確実に行われたことが確認される。
【0043】
なお、前記地雷探査装置17によりチェックを行うには、破壊した対人地雷のバネ等を回収することが必要であり、マグネット14にバッテリの直流(24v)を通電し、このマグネット14の部分に発生する強力な磁界で鉄、スクラップ、切屑等を吸着する。図3にその使用状態を示すが、ロータリーカッタ9を傾け、マグネット14を地上に近づけることでおこなう。
【0044】
これらマグネット14に吸着した鉄、スクラップ、切屑等は、所定の位置に運搬し、マグネット14を消磁すると、マグネット14から外れる。
【0045】
【発明の効果】
以上述べたように本発明の地雷処理装置は、バックホウ等のショベル機で使用する重機車両のブーム、アーム、ブームシリンダ、アームシリンダ、バケットシリンダで構成された起伏かつ屈折自在なアーム部の先端に、着脱自在にロータリーカッタを取り付ける地雷処理装置において、地雷探査装置をロータリーカッタの邪魔にならないように、安定した状態で設けることができ、確実に地雷探査を行うことができるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a landmine treatment apparatus that can efficiently process landmines and that can also secure farmland by improving farmland.
[0002]
[Prior art]
Conventionally, the handling of mines for personal use among mines has been carried out manually. Specifically, the detection is done one by one using a mine detector, which is similar to a metal detector, usually fixed to a long rod. If you can detect it, water it, soften the soil and check the status of the mine. After removing the soil with a brush or the like to make the mine visible, the gunpowder is set up to explode, and in this way the conventional mine treatment depends on the experience and kang of specialists one by one. It goes without saying that you have to spend a lot of time and effort.
[0003]
Therefore, by using a bulldozer type or excavator type for landmine sweeping by using an endless track vehicle, it is possible to efficiently sweep away without being exposed to the dangers associated with landmine sweeping. Various proposals have been made. As shown in FIG. 10, the inventor also cuts a cutter bit on the peripheral surface of the rotating drum 10 instead of the bucket at the tip of the undulating and bendable arm portion 2 of the heavy vehicle 1 used in the excavator such as a backhoe. No. 301608, Patent No. 3096847, inventing No. 301608, No. 3096847, inventing a rotary cutter 9 that can be cut to a depth of about 30 cm or more and can be discharged to the opposite side of the traveling direction. No. 3177737 was obtained.
[0004]

JP 11-183095 A (Patent No. 3177737)
[Patent Document 2]
JP 2000-130996 (Patent No. 3016018)
[Patent Document 3]
JP 2001-74398 A (Patent No. 3096847)
[0005]
In the figure, reference numeral 3 denotes a crawler track for traveling, but in addition to such a crawler type, it may be of a wheel type having wheels instead of the crawler belt.
[0006]
The undulating and bendable arm portion 2 is composed of a boom 2a, an arm 2b, a boom cylinder 2c, an arm cylinder 2d, and a bucket cylinder 2e, and the tip of the link mechanism 5a has a holding interval between the pin 6 on the attachment side. An attachment attachment / detachment device 5 incorporating a variable screw handle type slide mechanism 5b is provided. This attachment attaching / detaching device 5 can be reassembled without removing the attachment pins 6 and is called a quick hitch.
[0007]
A special bulletproof glass 7 made of a polycarbonate plate is adopted for the window glass of the driver's seat 3, and a guard 8 made of a mesh steel net is provided on the front surface thereof.
[0008]
The rotary cutter 9 has a rake 26 projecting laterally and a flap-type anti-scattering blade 27 on the back side.
[0009]
Rotating while rotating the rotary cutter 9, operating the boom 2a and arm 2b, cutting and crushing bushes, grass, etc. growing in the wasteland, and at the same time crushing anti-personnel mines buried under the ground surface at once be able to. In particular, the rotary cutter 9 that rotates at a high speed can be cut to a depth of about 30 cm, so even if the anti-personnel mine is buried in the soil, it will be excavated and the anti-personnel mine hit when the cutter bit 11 contacts the mine. It is deformed, the internal explosive series is destroyed, and the electric circuit is disconnected.
[0010]
The anti-personnel mine is caught in the rotary cutter 9 by the next tooth (cutter bit 11), the case and the lid are separated, and the explosives are shattered.
[0011]
For this reason, anti-personnel mines in electric fuzes do not explode at all, while in anti-personnel mines with mechanical fuzes, only the fuze is ruptured and the anti-personnel mine itself does not explode. Treated landmines are divided into cases, lids, and electric circuit boards and discharged to the ground. They are discharged to the opposite side of the direction of travel, so mud is not covered and buried on antipersonnel landmines. .
[0012]
Incidentally, in Japanese Patent Laid-Open No. 2000-130996 (Patent No. 3016018) of Patent Document 2, the landmine exploration device 17 is attached to the side at the tip of the arm portion 2. Although not shown, the landmine exploration device 17 is connected to a signal processing unit and a monitor CRT installed in the driver's seat 3.
[0013]
The mine exploration device 17 can be extended by a jack-type telescopic arm. The mine exploration device 17 is moved under certain conditions by the movement of the arm unit 2 and the movement of the jack-type telescopic arm, and is within 1 m underground. Detect buried objects and identify their materials and types. Mark the material, position and depth on the CRT.
[0014]
Mine exploration device 17 distinguishes antipersonnel mines from antitank landmines / unexploded bombs, and in the case of antitank landmines / unexploded shells, they are exposed with rake 26 or skeleton bucket of rotary cutter 9 and then transported to the explosion point by human power. In the case of antipersonnel mines, the rotary cutter 9 is destroyed by high-speed rotation. This landmine exploration device 17 is a metal detector or / and a laser probe, an ultrasonic probe, or the like.
[0015]
[Problems to be solved by the invention]
However, in the above-mentioned Patent Document 2, the landmine exploration device 17 is attached to the lateral side at the tip of the arm 2b of the undulating and refracting arm part 2, and is always located near the rotary cutter 9, and the rotary cutter 9 Even when landmine exploration is not performed during the operation, the movement with the arm 2b causes a large amount of movement, which may cause an unstable state and may interfere with the operation of the rotary cutter 9.
[0016]
In addition, if metal fragments, metal parts, metal balls, etc. scattered after the destruction of antipersonnel mines are attached to the rotary cutter 9, if this reacts to the mine exploration device 17, an appropriate and quick mine exploration can be performed. There will be no.
[0017]
The object of the present invention is to eliminate the disadvantages of the conventional example described above, and the tip of an undulating and bendable arm portion composed of a boom, an arm, a boom cylinder, an arm cylinder, and a bucket cylinder of a heavy machinery vehicle used in an excavator such as a backhoe. In addition, in a landmine treatment device that attaches a rotary cutter in a removable manner, a landmine exploration device that can be provided in a stable state so that it does not interfere with the rotary cutter, and can be used for landmine exploration reliably is provided. There is to do.
[0018]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a support arm of a mine exploration device rotatably on a boom of an undulating and bending arm part so that the support arm intersects the arm when the rotary cutter is not used.

Reference numerals 20a and 20b denote expansion and contraction cylinders that connect and contract the inner tube 15a and the outer tube 15b, and the outer tube 15b and the sheath tube 18, respectively.
[0030]
The central portion of the sheath tube 18 is pivotally attached to the boom 2a of the undulating and refracting arm portion 2, and a sensor cylinder 21 is spanned over them. As a result, the support arm 15 is rotatably provided on the boom 2a.
[0031]
Next, the usage will be described. FIG. 9 is a block diagram showing the use process of the landmine disposal device of the present invention, which is divided into landmine exploration work and exploration landmine disposal work, and the treatment work is for antipersonnel landmines, anti-tank landmines, unexploded shells. And divided.
[0032]
The exploration work is carried out by bringing the landmine exploration device 17 close to a place where there is expected to be a landmine based on the results of preliminary surveys of various information. However, as shown in FIG. The bendable arm portion 2 is folded at an acute angle with respect to the boom 2a, and the rotary cutter 9 is positioned so as to approach the driver's seat 3 side.
[0033]
On the other hand, the support arm 15 of the mine exploration device 17 including the sheath tube 18 intersects the arm 2b, and the support arm 15 is extended from the sheath tube 18 so that the mine exploration device 17 is brought close to the surface of the ground.
[0034]
The exploration work by the mine exploration device 17 is performed in two stages. The first stage works in the detection mode. The bottom of the sensor unit is kept at a constant height of 5 to 10 cm above the ground, and the boom 2a is turned at a turning speed of 2 km / h to 4 km / h to perform detection work.
[0035]
When a mine or unexploded bomb is detected in the ground, a sound discovery signal is emitted. Subsequently, the mode is switched to the second precision mode and accurate information is detected. The landmine exploration device 17 is repeatedly scanned before and after the discovery position to clarify the type of buried object, the exact depth, position, and material type, and project and record it on the CRT.
[0036]
When the position is determined, the landmine exploration device 17 is stopped on the landmine or the like, and although not shown, marking is performed on the ground with a marking paint by a marking system incorporated in the landmine exploration device 17 itself or in the vicinity thereof.
