Abstract

PROBLEM TO BE SOLVED: To provide an apparatus for removing a mine buried under the ground surface surely and efficiently without exposing a worker to danger. SOLUTION: The mine remover 1 comprises a plurality of press wheels 4, a shaft 5 penetrating the press wheel group, a pair of supporting arms 7, and a protective plate 12 fixed to the supporting arm 7. The pressure wheels 4 are arranged independently from each other while touching in the lateral direction, and the outside diameter of the shaft 5 is set smaller than the inside diameter of the press wheel 4 so that the press wheels 4 can move individually. The supporting arm 7 supporting the shaft 5 on one end side thereof is fixed to a vehicle on the other end side, and the protective plate 12 is disposed on the rear side of the press wheel group in order to screen bomb blast. Since a mine can be triggered by pressing the ground surface even if it is buried under a rough surface or in a depressed ground or at a relatively deep position, a worker can remove the mine surely and efficiently without being exposed to danger.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mine removing device for mechanically blasting and removing mine.

[0002]

2. Description of the Related Art Land mines are roughly divided into two types: anti-tank mines and anti-personnel mines. Both are buried in the ground and used to explode when vehicles such as tanks or people pass over them. .

[0003] Once these land mines are buried in the ground, their explosive effects remain for an extremely long period of time, and in the event of a war, the front lines and military bases where only soldiers approach are quickly transformed into a place of life when the war ends. As a result, antipersonnel mines, especially adults and children, explode at the feet of those who step on them,
Causes cruel damage.

Conventionally, in order to remove such a mine, a worker wears protective equipment, holds a mine detector, that is, a metal detector, slowly and quietly on the ground, and attaches the mine to the mine. The method of detecting metal is exclusively used.

In the case of anti-tank mines, it is relatively easy to find them because a lot of metal is used. However, in the case of anti-personnel mines, a small metal ignition device (fuze) is usually used.
Others use significantly less metal, so it is necessary to find this small metal. Then, when the metal detector reacts, an elongated metal rod is inserted into the ground to determine the size of the object and determine whether or not it is a mine. If you find a mine in this way, carefully remove it or set up an explosive and blast it remotely,
Remove.

[0006]

However, the method of manually finding a mine by holding such a metal detector is based on the fact that the metal detector reacts to any metal such as nails, tacks, and bullet fragments. This is a very time-consuming method in which the detector reacts too many times and finally hits a single mine. In addition, there is a disadvantage that it is difficult to detect on a land where a large amount of metallic substances such as iron are contained in the soil. In addition, such removal methods require you to work while maintaining tension in hot weather,
It is a very dangerous operation that involves accidents such as slipping or suddenly stepping on a mine, causing serious injury or death.

For this reason, for example, a special vehicle such as a tank or a bulldozer is attached with a long arm, and is dug up from a distance with a large mulberry or a ski, or a chain attached with a weight on the front of these vehicles. Attempts have also been made to attach lands and blow the mine by hitting the ground. However, these methods also have a safety zone where land mines are buried a little deeper or buried in depressions, so that they can be left behind and completely removed and can be entered by people. This is not a sufficient method.

Accordingly, an object of the present invention is to provide a device capable of reliably and efficiently removing a land mine buried in the ground without leaving the worker in danger, as described above. That is.

[0009]

In order to solve the above problems, the present invention employs the following method.

That is, the demining device comprises a plurality of pressure wheels,
A shaft penetrating the pressurizing wheel group, a support arm, and a protective plate attached to the support arm are formed, and the pressurizing wheels are arranged independently of each other and laterally so as to be in contact with each other,
The outer diameter of the shaft is formed smaller than the inner diameter of the pressure wheel so that the pressure wheels can move individually, and the support arm is
One end of the shaft supports both sides of the pressure wheel group, the other end of the shaft is attached to the vehicle, and the protection plate is attached to the rear position of the pressure wheel group to block the blast. It was done.

[0011] In this manner, the vehicle can push the pressurized wheel group via the support arm to advance the ground in which the land mines are buried. And since each said pressurizing wheel can move up and down independently in the width direction independently of each other, even when the mine is buried in the uneven ground or depression, the pressurization corresponding to these recessed positions is performed. The ring falls and pressurizes its ground, which can detonate mines. In addition, if each pressurizing wheel has a sufficient weight to detonate an antipersonnel mine, even if the mine is buried a little deeper, the ground can be depressed and detonated. As a result, the mine can be detonated without being left behind, and can be reliably removed.

Since a protective plate is provided at the rear of the pressure wheel group, the blast can be blocked, so that the operator and the vehicle operating the vehicle equipped with the demining device can be protected from the blast.

[0013] Thus, the worker detonates without leaving any mines without exposing himself to the dangers described above,
Can be removed.

It is preferable that the outer peripheral surface of the pressure wheel is formed in an uneven shape.

[0015] In this way, the press wheel is more likely to bite into the ground and rotate more easily, so that the demining device can be more easily advanced.

It is desirable to fit a sliding sleeve on the shaft.

With this arrangement, since the inner peripheral surface of the pressure wheel and the sliding sleeve come into contact with each other, the rotation of the pressure wheel is performed more smoothly. Can be more easily advanced.

Further, since the shaft does not directly contact the inner peripheral surface of the pressure wheel, it is not necessary to consider the slidability.
Materials having the required mechanical properties can be selected.

It is preferable that the protection plate is swingably supported by the support arm.

In this way, when the mine removing device advances on the uneven ground, even if the lower end of the protective plate contacts the ground, the resistance is small and does not hinder the advance. Then, when blocking the blast caused by the detonation of the mine, this protection plate can swing to reduce the impact pressure due to the blast. The protection plate that has received the blast collides with the outer peripheral surface of the pressure wheel and stops.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG.
Explanation will be made based on FIG.

FIGS. 1 and 2 show a mine eliminator 1 according to an embodiment of the present invention. The mine remover 1 has a cylindrical ring 2 made of a steel plate and a non-slip ring attached to an outer peripheral surface thereof by welding. A plurality of pressure wheels 4 formed from the uneven member 3 are arranged in a lateral direction so as to be independent of and in contact with each other. A shaft 5 whose outer diameter is smaller than the inner diameter of the pressurizing wheel 4 penetrates the pressurizing wheel group so that the pressurizing wheel 4 can individually move up and down. The sleeve 6 is rotatably fitted.

The shaft 5 is fixedly supported by welding to one end of a pair of support arms 7 on both sides of the pressure wheel group. As shown in FIGS. 1 and 3, the other end of the support arm 7 is inserted through a support pin 10 attached to a support block 9, and a spring washer 11 is fitted in and supported rotatably. The support block 9 is fitted into a bumper of a conventional vehicle 8 such as a four-wheel drive vehicle and fixed by welding.

At the rear of the pressure wheel group, a protective plate 12 for blocking a blast is provided, the upper end of which is higher than the top of the pressure wheel 4 and the lower end thereof approaches the ground. It is provided at an angle. On the rear surface of the protection plate 12, a rod 13 is protruded at both ends from both ends of the protection plate 12 toward the upper end side from the center of the rear surface in order to make it easier to incline toward the pressure wheel group. Welded to. Both ends of the rod 13 are rotatably supported by the support arm 7 so that the protection plate 12 can swing.

The embodiment of the present invention is configured as described above, and its operation will be described below.

When the wheel 8 is pressed by the car 8 via the support arm 7 at such a speed that a person walks normally, the support arm 7 is rotatably supported around the support pin 10.
The shaft 5 is lifted from the initial position shown by the chain line to the position shown in the figure. Thereafter, the shaft 5 tries to rotate downward by its own weight, and exerts a downward force on the inner peripheral surface of the pressure wheel 4. The pressurizing wheel 4 is urged by this force, rotated by being pushed by the vehicle 8, and moves forward on the ground.

Since each pressure wheel 4 can move up and down independently of each other, as shown in FIG. 4, even when the land mine 14 is buried in the uneven ground or in the depression, it is possible to use these depressions. The press wheel 4 corresponding to the salient position falls and pressurizes the ground, so that a land mine can be detonated. Further, since each pressure wheel 4 has a sufficient weight to detonate the mine 14, even if the mine 14 is buried a little deeper,
The ground can be pressurized and detonated.

Protective plate 12 provided at the rear of the pressure wheel group
Is supported by a rod 13 fixed to the back of the support arm 7.
Therefore, even when the lower end of the protection plate 12 comes into contact with the ground, the resistance is small and does not hinder the advance when the vehicle moves forward on the uneven ground. When blocking the blast caused by the detonation of the mine, the protection plate 12 swings to reduce the impact pressure due to the blast, and the demining device 1
Damage can also be prevented. The protection plate 12 that has received the blast collides with the uneven member 3 on the outer peripheral surface of the pressure wheel 4 and stops.

In this manner, the worker operating the car 8 equipped with the mine removal device 1 and the vehicle body can be protected from the blast, and the worker can remove the mine without exposing himself to the above-mentioned danger. It can be detonated without leaving behind, and can be removed reliably and efficiently.

Further, the unevenness member 3 attached to the outer peripheral surface of the pressing wheel 4 allows the pressing wheel 4 to bite into the ground and to be more easily rotated, thereby removing the uneven ground or the depressed ground from the demining device 1. Is easier to move forward.

Further, since the inner peripheral surface of the pressure wheel 4 comes into contact with the sliding sleeve 6, the rotation of the pressure wheel 4 is performed more smoothly, and as described above, the mine removing device 1 is further advanced. You can make it easier.

Further, since the shaft 5 does not directly contact the inner peripheral surface of the pressure wheel 4, a material having required mechanical properties can be selected without considering slidability.

To give a specific example of the mine eliminator 1 mainly for removing antipersonnel mines, the ring 2 has a thickness of 1 mm.
A 9 mm steel plate is formed into a cylindrical shape having an outer diameter of 600 mm, and the width is adjusted to 200 mm. The concavo-convex member 3 is formed by processing a steel plate having a thickness of 16 mm into a concavo-convex shape, and is attached to the outer peripheral surface of the ring 2 by welding to form the pressing wheel 4 as described above. As the shaft 5 penetrating the pressurized wheel group, a tempering material such as a tough steel having an outer diameter of 200 mm can be used, and a 12 mm-thick steel plate can be used as the protective plate 12. The support arm 7 also has a thickness of 1
It can be formed from a 9 mm steel plate. The sleeve 6 fitted into the shaft 5 can be formed of a commonly used bearing alloy such as a copper alloy, an aluminum alloy, and a bronze alloy.

The pressing wheels 4 can be arranged in a horizontal direction of ten wheels. In this case, the width of the pressing wheel group is about 2,000.
mm, and the support arm 7 can be attached to a normal four-wheel drive vehicle without any trouble.

Further, since the pressure wheel 4 has a sufficient weight, it does not jump up against the blast, and the shaft 5, the support arm 7, the protection plate 12 and the like have sufficient strength against the blast. Therefore, there is no possibility that the land mine removal device 1 will be damaged, and there is no problem with respect to safety for workers.

On the other hand, when the anti-tank mine is to be removed, the unit weight is increased by increasing the thickness or width of the pressurizing wheel 4 in order to apply the force required for detonation. By increasing the thickness of the support arm 7 and the protection plate 12 to make it more robust, and fixing the support arm 7 to a caterpillar vehicle such as a tank or a bulldozer, similar to the case of anti-personnel land mines described above, The buried land mines can be detonated without being left behind, and can be reliably and efficiently removed.

[0037]

As described above, according to the mine elimination device of the present invention, each of the pressurized wheels can move up and down independently of each other, so that the mine is buried in the uneven ground or depression. Even in that case, the ground can be pressurized and detonated. In addition, since the individual pressure wheels have a sufficient weight to detonate the mine, even if the mine is buried a little deeper, the ground can be depressed and detonated.

Further, since a protective plate is provided at the rear of the pressurizing wheel group so as to be able to swing, it is possible to block the blast and reduce the impact pressure due to the blast. The maneuvering worker and the vehicle body can be protected from the blast.

As described above, the worker can detonate without removing any of the anti-personnel mines or anti-tank mines buried in the ground without exposing himself to the above-mentioned danger, and remove the mines reliably and efficiently. can do.
