Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for treating land mines buried in a battlefield, and more particularly to a device for demining landmines that disposes by detonating land mines.

[0002]

2. Description of the Related Art Conventionally, as a method of disposing landmines, a method of artificially removing them has been generally used, but this method is very dangerous and inefficient.
Instead, several types of methods for mechanically disposing landmines have been proposed. As a treatment method, the landmines are not directly recovered, but in most cases, the landmines are exploded.

As such a blast treatment method, there is a remote control method such as electromagnetic wave (electromagnetic pulse) or laser,
There is a method of applying physical force directly to land mines to explode them. The former is effective only for land mines that have a function of making the device itself expensive and causing electromagnetic detonation, or there is a problem that scanning is leaked or scanning takes time because the beam of the laser is thin. is there. However, not only anti-personnel mines but also anti-tank mines, there are many primitive sensor functions, and the latter physical force is used as an effective blast treatment means for all mines. It is effective to do.

As such a physical treatment method, for example, a method using pressurized water (Japanese Patent Laid-Open No. 2000-17119) is used.
8), a method of destroying with a rotary cutter (Japanese Patent Application Laid-Open No. 2-6
000-130996), a method of utilizing the hammer action of a weight (JP-A-11-316100), a method of injecting compressed air (JP-A-11-304400), and the like.

[0005]

The above-mentioned means for solving the problems by the physical method have advantages and disadvantages in that the device itself is mechanical. For example, when using pressurized water, a large amount of water is required, but the places where the water resources are scarce, such as desert areas and mountainous areas, become battlefields, and it is difficult to secure water in such areas. , If it is buried relatively deeply, it is difficult to affect land mines unless it is jetted at high water pressure for a long time, so high-pressure pump equipment is also required.

Further, when the rotary cutter is used, there is also a problem that the rotary and the rotating mechanism are damaged when the land mine is ruptured. When the hammer of the weight is used, the impact by the weight accurately covers a predetermined area. There is a problem that it is difficult to cover all of them, and the chains connecting the weights and mechanical parts are damaged. Furthermore, the method of injecting compressed air cannot be expected to have a high impact effect, and has the same problem as the above-mentioned pressurized water.

Therefore, the inventor of the present invention has conducted research toward a method of giving a shock to a buried land mine, and a method using water, which is often difficult to obtain, or a compressed air having an insufficient shock force. We decided to give up on the method of using, and at the same time, we decided to throw away the weight hammer and rotary method that cause damage to the mechanical part.

The present invention has been made in view of the above-mentioned prior art, and an object of the present invention is to provide a landmine blasting treatment device capable of safely and reliably blasting landmines with a simple device.

[0009]

In order to achieve the above object, a landmine blast treatment apparatus according to the present invention is provided with a blast projection means 2 on a traveling vehicle 1 which is configured to be capable of traveling by radio control, and the traveling vehicle 1 is provided with the blast projection means 2. A blast guard 3 is provided on at least the front surface, and the blast 1 is provided by the blast projection means 2.
It is configured so that 0 can be projected toward the lower front of the traveling vehicle 1.

In the present invention, it is preferable that the blast 10 is a pebble.

Further, in the present invention, the blast 10
Are preferably steel balls.

Further, in the present invention n, a towing vehicle 4 is connected to the rear portion of the traveling vehicle, blast recovery means 5 is provided on the towing vehicle 4, and the recovered blast 10 is carried into the traveling vehicle 1. Means 6 are preferably provided.

Further, in the present invention, it is preferable that the blast projection means 2 includes a blast hopper 2a, a supply screw conveyor 2b, and at least one projection unit 2c.

Further, in the present invention, it is preferable that the blast recovery means 5 includes a scraper conveyor 5A and a blast selection means 5B.

Further, in the present invention, it is preferable that the towing vehicle 4 is provided with a generator unit 7 and the traveling vehicle 1 is driven by an electric motor.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention preferably employs, as the traveling means of the traveling vehicle 1, an endless track system such as a tank shown in the embodiment resistant to blast, but can also be implemented by a normal tire system. The same applies to the towing vehicle 4, and instead of the tire system shown in the embodiment, the track system may be adopted. Further, as the driving means of the traveling vehicle 1, an electric motor with less vibration is used here for use in anti-ground mines where vibration propagation is to be avoided as much as possible. However, if it has a sufficient vibration isolation function, it is a reciprocating engine. Is also good. As a power source of the present invention, a generator unit 7 by a reciprocating engine (a diesel engine in this embodiment) is used as a towing vehicle 4
However, in this case, since it is far from the traveling vehicle 1 in the vicinity of the landmine, unexpected vibration is unlikely to affect the landmine.

When pebble is used as the blast of the present invention, it can be appropriately selected whether it is natural stone or crushed stone pieces. When steel balls are used, they may be substantially the same as steel balls or steel balls, for example, bronze, lead, those made of various alloys, etc., for example, used in various industrial fields. It is also possible to use a small diameter steel ball used for shot blasting, or a larger diameter bearing ball.

The blast guard 3 is for protecting the main body (internal equipment) of the traveling vehicle 1 when a land mine explodes, and is made of high-strength steel (special alloy) in this embodiment. However, it may be made of synthetic material such as reinforced plastic or glass fiber, or may be a normal steel plate as long as it has a sufficient thickness.

The blast recovery means 5 selects pebbles or steel balls from the soil scooped together when recovering the blast 10 (pebbles or steel balls) projected on the ground, and reuses the blast 10. In this embodiment, a coarse screen and a fine screen are used. However, when the blast 10 is a magnetic material of steel balls,
If a selecting means using an electromagnet is provided, more effective selecting can be performed. Needless to say, if the blast 10 is a pebble and the pebble is available at the site, the pebble may be disposable and there is no need to install such a blast collecting means 5.

As described above, according to the land mine blasting treatment apparatus of the present invention, unlike the explosive means such as the pressurized water, the compressed air, the hammer, etc. , It is possible to secure sufficient kinetic energy, and it is possible to cause landmines to explode with its large projection impact force. Furthermore, particularly when a metal ball such as a steel ball is used as the blast, the projected blast is immediately collected and reused, which eliminates waste of one-way passage of the projection material and protects the natural environment.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a land mine blast treatment apparatus according to the present invention will be described in detail below with reference to the drawings. As shown in FIGS. 1 and 2, in this land mine blast treatment device, a towing vehicle 4 is connected to a rear portion of a traveling vehicle 1 having a self-propelled function, and a connecting member 12 is provided.
Blast projection means 2 connected to the traveling vehicle 1
Is provided, the blast projection means 2 is configured to project the blast 10 toward the lower front of the traveling vehicle 1, and a blast guard 3 is provided on the front surface of the traveling vehicle 1, and the traction vehicle is further provided. 4 is provided with a blast collecting means 5 and a conveying means 6 for carrying the collected blast 10 into the traveling vehicle 1. In this example, the pebbles of the blast 10 (assuming a specific gravity of 1.4) are approximately 10 m.
A mixture of m-square or more and preferably about 20 mm is used.

The selection of the pebbles is based on the following assumptions. Anti-personnel landmines were calculated on the assumption that a child (about 30 kg in weight) will cause an explosion even when stepped on, and that this level of collision force can be exerted. If the pebbles of the blast 10 to be projected are about 20 mm square, the result is as follows. Kinetic energy: Ek = W / 2g · V (kgm) V (projection speed) V = 65m / s W (pebble weight) W = 0.01kg (specific gravity 1.4) Ek = 2.16kgm Impact force: F = Ek / s (kg) Fuze stroke of land mine 0.01 m F = 216 kg If the pebbles are 10 mm square, the impact force is
It is 31 kg, which is close to the weight of a child. Further, when a steel ball (specific gravity 7.85) is used as the blast 10, the weight is 60 g (6
Times) and the collision force becomes 1296 kg. Therefore, very small particles or balls (2 mm to 10 m)
m). In the above calculation, the stroke to the fuse of the land mine is assumed to be 10 mm, but there are cases where the stroke is 5 mm and 20 mm.

The traveling vehicle 1 has an endless track, that is, a crawler type traveling mechanism such as a tank, and the traveling function itself has a known structure. Further, in this embodiment, it is configured to be operated by radio control, but since such radio control configuration and control mechanism itself may use known means, detailed description thereof will be omitted here.
In FIG. 1, M indicates a buried land mine.

The traveling vehicle 1 is driven by an electric motor in this embodiment, and its power source is a power generation unit 7 provided in the rear towing vehicle 4. The power generation unit 7 is driven by a diesel engine. Of course,
The electric power of the power generation unit 7 is supplied to an electric motor that activates the blast projection means 2, the blast recovery means 5, the transportation means 6 that carries the recovered blast 10 into the traveling vehicle 1, and the like. Needless to say, when the towing vehicle 4 is not connected, the traveling vehicle 1 is equipped with a power generation unit or a battery as a power source.

The blast projection means 2 comprises a blast hopper 2a, a supply screw conveyor 2b provided in the blast hopper 2a, and two projection units 2c. The projection unit 2c is known as a general shot blast, and is, for example,
Rotate the vanes to move steel balls at high speed (50-80m /
s) It is configured so that it can be projected. Figure 2
As can be seen from the above, in this embodiment, two sets of the respective constituent elements are eventually earned corresponding to the two projection units 2c. However, of course, it is not possible to adopt a configuration in which some of them are combined. It is possible to change the design as appropriate.
In addition, 13 shows a blast adjustment gate, and 14 shows a blast opening / closing gate.

Further, the blast recovery means 5 includes a scraper conveyor 5A and a blast selection means 5B. The scraper conveyor 5A is constructed by laying a large number of small buckets on a chain and scraping the ground. The scraped blast 10, soil, pebbles, etc. are provided with a coarse screen 8A. 8, the coarse pebbles and the like are sorted and discharged by the screen 8A, the brass and 10 and fine particles of sand are fried by the bucket elevator 9, and fine particles of sand are selected and removed by the fine screen 11. The blast 10 having a predetermined particle size is selected and is carried into the blast hopper 2a of the traveling vehicle 1 in front by the belt conveyor of the conveying means 6. Of course, when the blast 10 is a steel ball, an electromagnet may be applied as one of the sorting means.

The blast 10 used in this embodiment is
The size of pebbles is about 10 to 20 mm square, and the diameter of steel balls is about 2 to 10 mm, but even if the diameter is larger than this, the large kinetic energy can be used, so special land mines and It may be effective when the ground surface is hard. Further, although there are pebbles that pass through the screens 8A and 11 having a predetermined large and small mesh, these pebbles and the like may be used together.

[0028]

According to the landmine blasting apparatus of the present invention, it is possible to safely and reliably blast the landmines with a simple device by using a means of high kinetic energy called blast projection. As a result, valuable water such as conventional pressurized water is not required, there is no shortage of impact force such as compressed air, there is no uncertainty of scanning to a predetermined area such as weight hammer action, or explosion such as rotary method. There is an advantage that the landmines can be surely detonated without any damage caused by the.

If pebbles are used as the blast, they can be procured locally, and even if they are thrown away, no cost is required. Further, when steel balls are used, they can be collected and reused by laying a recovery means, and the cost can be kept low. Other specific effects of the present invention are as described in detail in the above-mentioned embodiments of the invention and the embodiments.
