Description

【0001】
【発明の属する技術分野】
この発明は、地雷原の対人地雷を、走行しながら爆破させて処理する地雷処理機に関する。
【0002】
【従来の技術】
現在、多くの紛争地域において、無数の対人地雷がばら蒔かれ、そのまま除去されずに放置されて、多数の人命が奪われていることは、周知のところである。世界中のボランティア団体や他の団体等が献身的に地雷撲滅作業を行っているが、現状の処理速度では、数百年の月日が必要とも言われている。
そのため、除去の効率化を目指して、種々の形式の地雷処理機が開発されている。例えば、車体にアームを介して爆破用のアタッチメントを設けたものが提案されている。また、車体に爆破用のロータを設けたものも提案されている。
【0003】
【発明が解決しようとする課題】
しかし、上記爆破用のアタッチメントを設けたものは、そのアタッチメントを降ろした範囲のみの地雷爆破を行うものであり、アタッチメントの昇降と車両の僅かな走行とを繰り返して行う必要があり、除去効率が悪い。上記ロータを設けた地雷処理機は、走行しながらロータで爆破するものであるため、効率的除去が可能であるが、地盤の傾斜やその他各種の状況により、地雷が除去できずに残る恐れがある。
【0004】
この発明の目的は、地雷原の種々の地盤状況下で多数の対人地雷を効率良く、漏れなく安全に除去することのできる地雷処理機を提供することである。
【0005】
【課題を解決するための手段】
この発明の地雷処理機は、走行車輪および走行駆動源を有する車体と、この車体の左右部にそれぞれ上下回動自在に取付けられて先端が車体の前方へ延びる一対のアームと、上記各アームを個別に上下回動させるアーム昇降回動駆動源と、上記一対のアームの先端間にロータ支持部材を介して設置され上記車体の前方で左右方向に延びる地雷爆破用のロータと、このロータを回転させるロータ回転駆動源と、無線操縦信号を受信して上記走行駆動源を制御可能な無線操縦受信機とを備える。上記ロータは回転軸の回りに複数のブレードが放射状にかつ軸方向に複数並び、上記車体の横幅よりも広い軸方向幅を有するものであり、上記ロータ支持部材は、上記一対のアームの先端位置の高さの違いに応じて上記ロータを傾き自在に支持するものとしている。
この構成によると、車体前方のロータを回転させながら走行することで、地盤の対人地雷を上記ロータで爆破しながら走行することができる。そのため、走行したロータ幅の範囲の地雷を全て除去することができ、効率的な地雷除去が行える。上記ロータは、複数のブレードが放射状にかつ軸方向に複数並んだものであるため、各ブレードが地盤表面から潜り込み、ある程度の深さに埋め込まれた地雷も除去することができる。対人地雷の埋め込まれる深さは、300mm程度までであり、この程度の深さまでに埋め込まれている地雷であれば、上記ブレードにより爆破させることができる。しかも、このような多数のブレードで構成されるロータを用い、また爆破により地雷除去を行うため、地雷除去後の地盤は、開耕された状態となり、農地等への利用が行い易い。例えば、深層土まで膨軟になり、透水性が向上する。また、一対のアームの先端位置の高さを異ならせることでロータの傾き角度変わるようにしたため、傾斜した地盤上においても、上記ロータを地盤の傾斜に沿って傾斜させることができる。そのため、ロータが地盤に対して一端側が浮き上がるようなことがなく、ロータ幅の範囲の地雷を確実に爆破できる。このように、地雷原の種々の状況下で多数の対人地雷を効率良く除去することができる。さらに、無線操縦によるため、遠隔操作により無人で走行させて作業が行え、作業者の安全が確保される。
【0006】
この発明において、上記ロータ支持部材に、上記ロータのほぼ上半部を覆う爆破物保護カバーを設けても良い。このように構成した場合、地雷の爆破により散乱する爆破物で各種の駆動源等が破損するのを防止でき、地雷処理作業を効率良く行うことができる。
【0007】
この発明において、上記ロータ支持部材に、上記ロータの前方に沿って、灌木,雑草等の除去が可能な刈払い機を設けても良い。このように構成した場合、地雷埋設部へのロータの接近に先立って、地雷埋設部に繁茂する灌木や雑草等を刈払い機で確実に除去できる。そのため、灌木や雑草等の生い茂る地帯においても、前作業で灌木伐採等を行うことなく、そのまま走行して地雷除去をすることができる。
【0008】
また、この発明において、各車輪の車体に対する高さを調整する車輪高さ調整機構と、各車輪に作用する荷重または車体の水平を検出する検出手段の検出信号に応じ、車体が水平姿勢となるように上記各車輪高さ調整機構を制御する車体姿勢制御手段を設けても良い。この構成の場合、地盤に走行方向の左右方向に傾斜した傾斜面があっても、車体が水平姿勢に保たれ、車体の転倒が防止される。車体が走行途中で万一転倒すると、地雷源を通って車体を起こしに行く作業が必要となるが、このような作業を皆無とできる。
【0009】
また、この発明において、上記ロータが地盤と水平になり、かつ上記ロータのブレードが地盤内に入る深さが設定深さ範囲を保つように、上記アーム昇降回動駆動源を制御するロータ姿勢・深さ制御手段を設けても良い。このように構成した場合、地盤に左右に傾く傾斜面があっても、ロータは常に地盤と水平となるように作動し、開耕の深さが一定になる。そのため、地勢に左右されることなく、地雷処理作業を確実にかつ効率良く行うことができる。特に、上記の車体姿勢制御手段とこのロータ姿勢・深さ制御手段を組み合わせた場合は、車体を水平に保って安定を図りながら、ロータを地盤の傾斜に沿わせることができ、地盤傾斜に影響されずに安定して確実な地雷除去ができ、除去後の地盤は安全の信頼性の高いものとなる。
【0010】
さらに、車体の走行速度に応じてロータ回転駆動源によるロータの回転速度を制御するロータ回転速度制御手段を設けても良い。地盤の土質が固いような場合、ロータの負荷や車体の走行駆動源の負荷が大きくなるが、ロータの回転速度がロータ回転速度制御手段で自動調整されることにより、過負荷が防止され、円滑かつ効率的な除去作業が維持される。
【0011】
上記ロータの各単位ロータにおける各ブレードは、先端が軸方向に対して斜めに屈曲したものであって、円周方向に並ぶ各ブレードの先端屈曲方向が交互に逆方向であっても良い。このように構成した場合、薄いブレードであっても、広い範囲の地盤に触れ、ブレードの配置密度が低くても、ロータ幅内の地盤の地雷が漏れなくブレードに触れることになる。そのため、漏れなく確実に地雷を除去することができ、またブレードの配置密度が低くて良いことから、ロータの回転や車体走行の負荷を小さくできる。
上記ロータは、上記回転軸の回りに複数のブレードを放射状に有する単位ロータが軸方向に複数並べて構成されたものとしても良い。この場合に、各単位ロータ毎に上記回転軸に対して交換自在なものとしても良い。また、上記各単位ロータにおける各ブレードは、回転軸に設けられたハブに対して、基端で個々に交換可能に取付けられたものであっても良い。この構成の場合、一部のブレードが破損しても、簡単にブレードや単位ロータを交換することができ、ブレードまたは単位ロータの交換のみで復旧が行える。なお、この他に、ロータや、ロータ付きのロータ支持部材、アームおよびロータのセット等の単位で交換自在としておくことで、損傷時に最小限の交換で済む。例えば、対戦車地雷等に触れた場合に、ロータ等が損傷することがあるが、このような場合の部品交換が最小で済む。なお、ロータは車体の前方に離れているため、対戦車地雷等に触れた場合でも、車体まで損傷することは、通常は生じない。
【0012】
【発明の実施の形態】
この発明の一実施形態を図面と共に説明する。この地雷処理機は、車体1の左右部に、それぞれ上下回動自在に一対のアーム2が取付けられ、これら両アーム2の車体1の前方へ延びる先端間にロータ支持部材3を介して、地雷爆破用のロータ4が取付けられる。車体1は、走行駆動源となるエンジン(図示せず)と、走行車輪5と、この走行車輪5の操舵装置(図示せず)と、両側のアーム2を個別に上下回動させるアーム昇降回動駆動源6と、無線操縦信号を受信して上記走行駆動源および操舵装置等を制御可能な無線操縦受信機8とを備える。ロータ4は、車体1の前方で左右方向に延びるように配置される。ロータ4は、その回転軸9の回りに放射状に延びるブレード10を軸方向に複数設けたものであり、車体1の横幅よりも広い軸方向幅を有する。ロータ支持部材3は、上記一対のアーム2の先端位置の高さの違いに応じてロータ4を傾き自在に支持できるように、自在継手等の傾きを許容する連結部材11を2個有しており、各連結部材11を介して両アーム2の先端に取付けられている。ロータ4は、その回転軸9が両端でロータ支持部材3に軸受(図示せず)を介して回転自在に支持されている。上記アーム昇降駆動源6は、一端を車体1の側部に、他端をアーム2にそれぞれ回動自在に連結した油圧シリンダからなる。ロータ支持部材3には、上記ロータ4の略上半部を覆う爆発物保護カバー12が設けられている。この保護カバー12の外側の一側部には、ロータ4を回転させるロータ回転駆動源7が設けられている。
【0013】
上記ロータ4は、具体的には図5に示すように、回転軸9の回りに複数のブレード10を放射状に有する単位ロータ14を、軸方向に複数並べて構成される。各単位ロータ14は、回転軸9に対して個々に交換可能とされている。各単位ロータ14における各ブレード10は、先端10aが軸方向に対して斜めに屈曲したものとされている。ブレード10は、特殊鋼材を使用して、強度の確保と軽量化とを図っており、大抵の物を破壊する性能を持たせてある。単位ロータ14は、図6(A),(B)に示すようにブレード10が円周方向に十字状等の放射状に並ぶ2種類の単位ロータ半部14A,14Bを軸方向に重ねて構成される。各単位ロータ半部14A,14Bにおける各ブレード先端10aの屈曲方向は、図6(C),(D)に示すように互いに逆向きとされている。これにより、両単位ロータ半部14A,14Bを軸方向に重ねて構成される単位ロータ14では、円周方向に並ぶ各ブレード10の先端10aの屈曲方向が交互に逆方向とされる。また、両単位ロータ半部14A,14Bは、ブレード10の位相角度が互いにブード間の角度の1/2ずつずれて組まれる。
【0014】
また、ロータ4における各単位ロータ14における各ブレード10は、回転軸9に設けられたハブ15に対して、基端で個々に交換可能に取付けられている。すなわち、ハブ15には図7に示すような断面コ字状のブレード取付部材16が放射状に複数設けられており、このブレード取付部材16内に一対のスペーサ17を介してブレード10の基端部10bが係止され、ブレード取付部材16の開口側を蓋締めする蓋部材18と共にブレード基端部10bをブレード取付部材16にボルト19で締結することにより、ブレード10がハブ15に交換可能に取付けられる。ブレード10の基端部10bは、その幅方向の両側に突出する山形の係合凸部20を有し、この係合凸部20を、上記一対のスペーサ17の互いに内向きとなる側部に形成された山形の係合凹部21に係合させることにより、ブレード基端部10bが上記ブレード取付部材16内に係止される。
【0015】
図1,図2に示すように、ロータ支持部材3には、ロータ4の前方に沿って、灌木,雑草等の除去が可能な刈払い機22が設けられている。この刈払い機22は、左右一対のチェーンソー等からなる。
【0016】
車体1には、図8に示すように、各走行車輪5の車体1に対する高さを調整する車輪高さ調整機構23が各走行車輪5に対応させてそれぞれ設けられる。また、各走行車輪5に作用する荷重または車体1の水平を検出する検出手段24の検出信号に応じて、車体1が水平姿勢となるように上記各車輪高さ調整機構23を制御する車体姿勢制御手段25が設けられている。これにより、地盤Gに傾斜があっても、車体1が転倒しないように制御され、またロータ深さも一定に保たれる。ここでは、地盤Gの傾斜面が20°までの傾斜角度であれば、車体1が水平姿勢を保ようにされている。
【0017】
また、車体1には、図9に示すように、ロータ4が地盤Gと水平になり、かつロータ4のブレード10が地盤G内に入る深さが設定深さ範囲を保つように、上記アーム昇降回動駆動源6を制御するロータ姿勢・深さ制御手段26が設けられている。ブレード10の地盤表面に対する埋まり込み深さは深さ検出手段(図示せず)によって検出される。その検出は、例えば車体1の傾きとアーム2の車体1に介する回動角度から行われる。アーム2の回動角度は、アーム2の基端の支持部等に設けられた角度検出器(図示せず)により検出される。ロータ4のブレード10は、対人地雷が埋め込まれている深さである、地盤G内に0〜30cmの範囲で、設定深さに入り込むように自動調整可能とされている。
また、車体1には、車体1の走行速度に応じてロータ回転駆動源7によるロータ4の回転速度を制御するロータ回転速度制御手段25が設けられている。このロータ回転速度制御手段25は、例えば車体1の走行駆動源にかかる負荷を検出する負荷稼働センサ(図示せず)等の検出信号に応答してロータ4の回転制御を行うものとされる。
【0018】
車体1の後部には、カウンタウェート28が設けられている。このカウンタウェート28は、地雷処理機の作業地域の土質などに合わせて変更可能とされている。また、車体1の後部にはヘッドライト(図示せず)も設けられおり、夜間の移動が可能とされている。この地雷処理機の非作業時の単なる走行時には、車体1の後部が走行前方とされる。
【0019】
また、この地雷処理機では、無線操縦受信機8で無線操縦信号を受信して行われる無線操縦の操作性機能として、キャリアセンス機能を有している。この機能は、この地雷処理機の近くに同じ周波数帯を使用している機械が居る場合に、自動的に無線操縦信号の周波数を変更する機能である。また、メンテナンス機能として集中異常モニターを備える。この機能により、故障箇所が即座に判る。このほか、上記異常モニターが作動した場合、手元の無線操縦機の警告ランプを作動させる機能も備える。これらの機能は、車体1に設けられている。
【0020】
上記構成の地雷処理機は地雷原を無人で走行しながら、地盤を回転するロータ4のブレード10で開耕することにより、地雷を爆破処理する。その操縦は、無線操縦信号を受信する無線操縦受信機8が走行駆動源および操舵装置(いずれも図示せず)等を制御することで行われる。
ロータ4は車体1の進行方向の前方に離して配置されるので、地雷の爆破が車体1に影響を与えることが少ない。ロータ4は、車体1の横幅よりも広く構成されており、車体1は、ロータ4で地雷が爆破により除去された地盤面を走行することになるため、車体1が地雷を踏んで損傷を受けることがない。このように走行しながら地雷を爆破して除去するため、対人地雷を効率良く除去することができる。例えば、ロータ4の幅が1.9〜2.3mとされ、車体1が毎時5km程度で走行するものとされ、この走行速度で走行したロータ幅の範囲が地雷除去されることになる。上記ロータ幅とすると、この地雷処理機のコンテナ輸送が可能である。
【0021】
ロータ支持部材3には、ロータ4の略上半部を覆う爆破物保護カバー12が設けられているので、地雷の爆破により散乱する爆破物で各種の駆動源等が破損するのを防止でき、地雷処理作業を効率良く行うことができる。さらに、ロータ支持部材3には、ロータ4の前方に沿って、灌木,雑草等の除去が可能な刈払い機22が設けられているので、地雷埋設部へのロータ4の接近に先立って、地雷埋設部に繁茂する灌木や雑草等を刈払い機22で確実に除去でき、ロータ4による地雷埋設部の開耕を容易に行うことができ、地雷処理作業をより効率良く行うことができる。
【0022】
さらに、各走行車輪5の車体1に対する高さを調整する車輪高さ調整機構23と、各走行車輪5に作用する荷重または車体1の水平を検出する検出手段24の検出信号に応じ、車体1が水平姿勢となるように上記各車輪高さ調整機構23を制御する車体姿勢制御手段25が設けられているので、図8のように、地盤Gに傾斜面があっても、車体1を水平姿勢に保つことができ、地勢に左右されることなく、地雷処理作業をより効率良く行うことができる。
【0023】
また、ロータ4が地盤Gと水平になり、かつロータ4のブレード10が地盤G内に入る深さが設定深さ範囲を保つように、アーム昇降回動駆動源6を制御するロータ姿勢・深さ制御手段26を設けられているので、図9のように、地盤Gに傾斜面があっても、ロータ4は常に地盤Gと水平となるように作動し、開耕の深さも一定になる。これにより、地形に左右されることなく、地雷処理作業を確実にかつ効率良く行うことができる。上記設定深さは、無線操縦受信機8を介して無線による変更が可能とされている。
【0024】
負荷に対しては、車体1の走行速度に応じてロータ回転駆動源7によるロータ4の回転速度を制御するロータ回転速度制御手段27が設けられているので、車体1の走行駆動源に負担がかからないように、ロータ4の回転速度が調整されることになり、地雷処理作業を円滑にかつ効率良く行うことができる。
【0025】
また、ロータ4の各単位ロータ14における各ブレード10は、先端10aが軸方向に対して斜めに屈曲したものであって、円周方向に並ぶ各ブレード10の先端屈曲方向が交互に逆方向となるようにされているので、ロータ4による地盤Gの開耕を能率良く行うことができる。
【0026】
さらに、ロータ4の各単位ロータ14が個々に交換自在とされ、かつ各単位ロータ14における各ブレード10は、回転軸9に設けられたハブ15に対して、基端で個々に交換可能に取付けられているので、メンテナンスが容易である。一部の単位ロータ14やブレード10が破損しても、簡単に単位ロータ14やブレード10の交換を行うことができる。この他に、ロータ4や、ロータ付きのロータ支持部材3、アーム2およびロータ4の組立部品等の単位で交換自在としておくことで、損傷時に最小限の交換で済む。例えば、対戦車地雷等に触れた場合にロータ等が損傷することがあるが、このような場合の部品交換が最小で済む。
【0027】
ロータ4は、作業時以外は回転しないものとされ、走行時の安全が確保される。また、この地雷処理機は、地雷除去後に、農地開墾用として簡単に転用可能である。
【0028】
【発明の効果】
この発明の地雷処理機は、走行車輪および走行駆動源を有する車体と、この車体の左右部にそれぞれ上下回動自在に取付けられて先端が車体の前方へ延びる一対のアームと、上記各アームを個別に上下回動させるアーム昇降回動駆動源と、上記一対のアームの先端間にロータ支持部材を介して設置され上記車体の前方で左右方向に延びる地雷爆破用のロータと、このロータを回転させるロータ回転駆動源と、無線操縦信号を受信して上記走行駆動源を制御可能な無線操縦受信機とを備え、上記ロータは回転軸の回りに複数のブレードが放射状にかつ軸方向に複数並び、上記車体の横幅よりも広い軸方向幅を有するものであり、上記ロータ支持部材は、上記一対のアームの先端位置の高さの違いに応じて上記ロータを傾き自在に支持するものとしたため、地雷原の種々の地盤状況下で多数の対人地雷を効率良く、漏れなく安全に除去することができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a land mine disposer that blasts and processes an antipersonnel mine in a minefield while traveling.
[0002]
[Prior art]
It is well known that countless anti-personnel mines are now being scattered in many conflict areas and left without being removed, resulting in the loss of many lives. Volunteer groups and other organizations around the world are dedicated to demining landmines, but it is said that the current processing speed will require hundreds of years.
Therefore, various types of land mine disposal machines have been developed with the aim of improving the efficiency of removal. For example, a vehicle body provided with an attachment for blasting via an arm has been proposed. Further, there has been proposed a vehicle in which a rotor for blasting is provided on a vehicle body.
[0003]
[Problems to be solved by the invention]
However, the one provided with the blast attachment described above performs mine blast only in the area where the attachment is lowered, and it is necessary to repeatedly perform the ascending and descending of the attachment and the slight running of the vehicle, and the removal efficiency is reduced. bad. A mine disposal machine equipped with the above-mentioned rotor can be efficiently removed because it blasts with the rotor while running, but there is a risk that the mine may not be removed due to the inclination of the ground and other various conditions. is there.
[0004]
An object of the present invention is to provide a land mine disposer capable of efficiently removing a large number of antipersonnel land mines without leakage under various ground conditions in a land mine field.
[0005]
[Means for Solving the Problems]
A land mine disposer according to the present invention includes a vehicle body having traveling wheels and a traveling drive source, a pair of arms attached to left and right portions of the vehicle body so as to be vertically rotatable, and having a tip extending forward of the vehicle body, and An arm lifting / lowering drive source for individually rotating vertically, a mine blast rotor installed between the tips of the pair of arms via a rotor support member and extending in the left-right direction in front of the vehicle body, and rotating the rotor And a radio steering receiver capable of receiving a radio steering signal and controlling the traveling drive source. The rotor has a plurality of blades arranged radially and axially around a rotation axis, and has an axial width larger than a lateral width of the vehicle body. The rotor support member has a tip position of the pair of arms. The rotor is tiltably supported in accordance with the difference in height.
According to this configuration, by traveling while rotating the rotor in front of the vehicle body, it is possible to travel while blasting antipersonnel mines on the ground with the rotor. Therefore, all land mines within the range of the rotor width that has traveled can be removed, and efficient land mines can be removed. Since the rotor has a plurality of blades arranged radially and in the axial direction, each blade can sink into the ground surface and also remove land mines embedded at a certain depth. The depth at which an antipersonnel mine is embedded is up to about 300 mm, and any mine embedded up to this depth can be blown up by the blade. Moreover, since the mine is removed by blasting using the rotor composed of such a large number of blades, the ground after the mine removal is in a plowed state, and is easily used for farmland and the like. For example, the soil expands to the deep soil, and the water permeability is improved. Further, since the inclination angle of the rotor is changed by changing the heights of the tip positions of the pair of arms, the rotor can be inclined along the inclination of the ground even on the inclined ground. Therefore, the rotor does not float at one end with respect to the ground, and land mines within the rotor width can be reliably blown up. In this manner, a large number of antipersonnel mines can be efficiently removed under various conditions of the minefield. Further, since the vehicle is operated by radio, the vehicle can be operated by remote operation without any driver, and the safety of the worker can be ensured.

[0008]
Further, in the present invention, the vehicle body is brought into a horizontal posture in accordance with a wheel height adjusting mechanism for adjusting the height of each wheel with respect to the vehicle body, and a load acting on each wheel or a detection signal of detecting means for detecting the level of the vehicle body. A vehicle body attitude control means for controlling each wheel height adjusting mechanism may be provided. In the case of this configuration, even if the ground has an inclined surface inclined in the left-right direction of the running direction, the vehicle body is kept in a horizontal posture, and the vehicle body is prevented from tipping over. If the vehicle body falls down while traveling, it is necessary to go up the vehicle body through a mine source, but such a work can be completely eliminated.
[0009]
Further, in the present invention, the rotor posture for controlling the arm lifting / lowering rotation driving source is controlled so that the rotor is horizontal with the ground and the depth of the blade of the rotor entering the ground keeps a set depth range. Depth control means may be provided. With this configuration, even if the ground has an inclined surface that is inclined left and right, the rotor always operates so as to be horizontal with the ground, and the depth of plowing is constant.

Further, a rotor rotation speed control means for controlling the rotation speed of the rotor by the rotor rotation drive source according to the traveling speed of the vehicle body may be provided. When the soil of the ground is hard, the load on the rotor and the load on the traveling drive source of the vehicle body increase.However, the rotor rotation speed is automatically adjusted by the rotor rotation speed control means, thereby preventing overload and smoothing. And efficient removal work is maintained.
[0011]
Each blade in each unit rotor of the rotor may have a tip bent obliquely with respect to the axial direction, and the tip bending directions of the blades arranged in the circumferential direction may be alternately opposite. With this configuration, even a thin blade touches a wide area of the ground, and even if the arrangement density of the blades is low, land mines in the ground within the rotor width touch the blade without leakage. Therefore, land mines can be reliably removed without leakage, and since the arrangement density of the blades can be low, the load on the rotation of the rotor and the running of the vehicle body can be reduced.
The rotor may be configured by arranging a plurality of unit rotors having a plurality of blades radially around the rotation axis in the axial direction. In this case, the rotation shaft may be exchangeable for each unit rotor. Further, each blade of each of the unit rotors may be individually and interchangeably attached at a base end to a hub provided on a rotating shaft. In this configuration, even if some of the blades are damaged, the blades and the unit rotor can be easily replaced, and the recovery can be performed only by replacing the blade or the unit rotor. In addition, if the rotor, the rotor supporting member with the rotor, the arm and the set of the rotor, and the like are freely replaceable, minimal replacement is possible in the event of damage. For example, when touching an anti-tank land mine or the like, the rotor or the like may be damaged. In such a case, the replacement of parts is minimized. Since the rotor is away from the front of the vehicle body, damage to the vehicle body does not usually occur even when the rotor touches an anti-tank mine or the like.
