Description

Shooting Range Warhead Recovery Device {Warhead Recovery Device for Shooting Range}

The present invention relates to a shooting range warhead recovery device, and more particularly, to a shooting range warhead recovery device for recovering a warhead that is installed behind the target site of the real shooting range.

Due to the nature of the work, guns and police agencies handling firearms are equipped with shooting ranges for training and some shooting ranges are also fired. .

For example, military units operate various ranges of shooting ranges, such as real-range outdoor shooting ranges (eg 250m, 200m, 100m) and outdoor or indoor zero range (50m, 25m, etc.). In general, in the rear of the target site, a non-elastic wall is provided so that the warhead is embedded in the soil or sand of the non-elastic wall, and in the indoor shooting range, the warhead is embedded in waste tires or tire chips.

As is well known, the warhead (copper-coated lead) of live bullets used in rifles and pistols is mainly composed of lead, so the environmental pollution caused by lead is very serious in the shooting range.

Specifically, in the case of an outdoor shooting range, lead is diffused around the inelastic wall, contaminating land and water quality, which causes serious environmental pollution.In the case of an indoor shooting range, the lead is scattered due to the collision of waste tires of warheads, causing indoor air. In addition to polluting the waste, it is difficult to recover waste tires at a high cost and to separate lead. Nevertheless, there are no suitable alternatives.

In addition, the above-described real shooting range has a problem that even if the warhead is rarely recovered or even recovered, the recovery rate is very low, thereby wasting valuable resources.

In addition, the live shooting range is exposed to the risk of safety accidents caused by grenade or dovetan. In other words, Ovaltan can be generated by inferior walls or obstacles, which can fly around and damage neighboring residents. Such safety accidents can be significantly reduced by recovering warheads more reliably.

As a solution to the problem related to the shooting range warhead recovery, the Korean War Utility Model No. 224018 (notice of 2001. 05. 15. 2001) has been proposed for the shooting range warhead container. This is a device for recovering lead coal of air guns, which is not applicable to recovering live bullet warheads, which are incomparable in the power of warheads.

In addition, the conventional carbo-recovery device also has a problem of doubling the noise pollution since the warhead hits the warhead-recovery device, so that significant noise and vibration are generated.

An object of the present invention is to solve the problems associated with the recovery of warheads in the shooting range as described above, while absorbing the energy of the warheads step by step to naturally converge in one place to collect the warhead warhead recovery device It is to provide.

Another object of the present invention, by safely recovering warheads close to the original without generating debris, it is possible to effectively prevent environmental pollution and safety accidents caused by warheads, and to contribute to resource recycling by increasing the warhead recovery rate.

Another object of the present invention, bulletproof soundproofing capable of reducing the safety accidents caused by grenade and dobitan as a bulletproof function, and to reduce noise pollution by minimizing noise and vibration that may occur during the warhead recovery process. It is to provide a warhead recovery device.

According to the present invention, a shooting range warhead recovery device is provided.

The shooting range warhead recovery apparatus according to the present invention includes a warhead induction chamber, a warhead refractive chamber, and an impact absorption roller.

The warhead induction chamber is provided behind the target site of the shooting range and has a shape of an all-optical narrow view having a wide inlet and a narrow outlet, so that the warhead converges toward the outlet while absorbing the energy of the warhead.

The warhead refraction chamber is provided at the outlet of the warhead induction chamber and has an annular inner contour to absorb the energy of the warhead by changing the traveling direction of the warhead.

The shock absorbing roller is rotatably installed adjacent to the outlet of the warhead induction chamber in the warhead refraction chamber, rotates by collision of the warhead to absorb the energy of the warhead and induces the warhead to safely rotate.

Preferably, the warhead induction chamber has a fallopian tube shape whose inclination angle is formed at an angle corresponding to the warhead angle of the warhead.

Preferably, the inner surface of the warhead induction chamber is corrugated, so that the rotational force of the warhead is suppressed and the frictional resistance is reduced to prevent the warhead from escaping.

Preferably, the warhead induction chamber and the warhead refraction chamber is made of a bulletproof wear-resistant steel plate, and the outer surface of the warhead induction chamber and the warhead refraction chamber is covered with a sound insulating material to prevent the spread of noise and vibration due to the impact of the warhead.

Preferably, a discharge port for discharging the recovered warhead to the outside is formed in the lower side of the warhead refraction chamber, the detachable warhead recovery container is connected to the discharge port.

Second, the shooting range warhead recovery apparatus of the present invention, since the energy of the warhead is sequentially absorbed safely through the multi-step warhead guide chamber, warhead refraction chamber and impact absorption roller having an inclined angle corresponding to the warhead angle, warhead It can be safely recovered close to the original shape without generating debris, and can minimize the generation of lead dust.

Third, the shooting range warhead recovery device according to the present invention, by recovering the warhead in the structure of the all-light bolster of the wear-resistant steel sheet material, the bulletproof function is very excellent, can reduce the grenade and dobitan, so that the shooting range safety accidents can be prevented There is.

Fourth, the shooting range warhead recovery apparatus according to the present invention can minimize the noise and vibration generated in the warhead recovery process by applying the sound insulation material.

Hereinafter, a shooting range warhead recovery device according to the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are merely illustrative of the shooting range warhead recovery apparatus according to the present invention is not intended to limit the scope of the present invention.

1 to 6, the shooting range warhead recovery apparatus 1 according to the present invention basically includes a warhead induction chamber 10, a warhead refraction chamber 20, and an impact absorbing roller 30. It is comprised, and is provided in the back of the target site 2 of various bullet shooting ranges.

The warhead induction chamber 10 is installed at the rear of the target site 2 to induce to collect and recover the flying warhead 3 to one place, and primarily to impart energy (impact) of the colliding warhead 3. The inlet 11 is wide and the outlet 12 is in the shape of a narrow all-light narrowed side.

In the shape of the warhead guide chamber 10, a wide inlet 11 is formed to cover a large area behind the target site 2, and the warhead 3 introduced through the inlet 11 is narrowly formed. The structure of the all-optical confinement that can converge to the exit 12 is not particularly limited.

1 to 4 show an example of a warhead induction chamber 10 in the shape of a fallopian tube (funnel) having a substantially circular cross section, and the embodiments of FIGS. 5 and 6 have a substantially rectangular cross section. An example of a warhead induction chamber 10 is shown.

The former cross-sectional circular warhead induction chamber 10 is suitable for an individual device that covers one target site 2 with one warhead recovery device 1, and the latter rectangular warhead induction room 10 has one warhead recovery device. (1) is suitable for an integrated device covering several target papers (2).

The warhead induction chamber 10 is a member in which the flying warhead 3 collides for the first time, and thus, when a general steel sheet is used, ballistic induction chamber 10 has a problem of bulletproof and its life is very short. Silver is made of a material having strength that can withstand the destructive force of the warhead 3 sufficiently.

For example, the warhead induction chamber 10 may be made of a bulletproof steel sheet such as a special wear resistant steel sheet (eg, AR steel sheet) containing low carbon boron (BORON). Not only does it have a function, it can be used semi-permanently.

Most of the warheads 3 passing through the target site 2 collide with the inner wall of the warhead induction chamber 10. Therefore, the warhead 3 collides with the warhead induction chamber 10 at a large angle of incidence to generate grenade. In addition to preventing and using the straightness and rotational force of the warhead 3, the inclination angle θ1 of the all-optical narrow of the warhead guidance chamber 10 is guided toward the warhead refraction chamber 20 as if the warhead 3 naturally slides. It is preferable to determine the angle corresponding to the warhead angle θ2 of the warhead 3 (see Fig. 2).

Since the warhead angle (θ2) is different depending on the type of bullet, the warhead angle (θ2) of the rifle bullet is generally 12 ° to 15 °, so the warhead recovery device 1 of the present invention can be applied to a rifle shooting range. In this case, the inclination angle θ1 of the warhead induction chamber 10 may also be set to about 12 ° to 15 °.

In addition, although the contour of the inner wall of the warhead induction chamber 10 may be flat, as shown in FIG. It is possible to more effectively prevent the warhead 3 from escaping out of the warhead induction chamber 10 by suppressing its rotational force against the warhead 3 and reducing the frictional resistance.

The warhead induction chamber 10 according to the characteristic configuration of the warhead induction chamber 10, the inclination angle θ1 corresponding to the warhead angle θ2 of the warhead, and the corrugated inner wall contour. The warhead (3), which hits it, moves naturally toward the warhead refraction chamber (20) as if it slides along the warhead induction chamber (10) without deviation, and in the process absorbs the energy of the warhead (3) to its upper limit and its speed and rotational force It is to reduce the, as the warhead (3) is naturally induced is also to the extent of bulletproof and soundproofing.

In addition, since the warhead induction chamber 10 is in the shape of an all-optical narrow, it is possible to recover most of the warheads 3 except for some warheads that are completely off target, even when shooting from any angle.

Although the impact of the warhead 3 can be effectively absorbed due to the structural features of the warhead induction chamber 10 described above, the warhead induction chamber 10 is made of a wear-resistant steel sheet, Since it is difficult to avoid the occurrence of noise and vibration, in order to minimize such noise and vibration, the sound insulating material 40 may be coated on the outer surface of the warhead induction chamber 10. As the sound insulation material 40, a butyl-based sound insulation sheet widely used as a sound insulation, sound insulation, and a vibration damping material may be used.

As shown in FIG. 1, the warhead induction chamber 10 may be supported by a pedestal 60.

The warhead refraction chamber 20 is a chamber member having an inner contour of an annular (eg, spherical or cylindrical) shape, which is continuously connected to the outlet 12 of the warhead induction chamber 10, and has a shock absorption described later in the interior space. The roller 30 is provided and absorbs the energy of the warhead 3 in cooperation with the shock absorbing roller 30 by changing the traveling direction of the warhead 3.

The warhead (3) which stops flying due to the loss of energy is gathered toward the bottom of the warhead refraction chamber (20) by its own weight, and preferably the warhead refraction chamber (3) recovered below the warhead refraction chamber (20) The discharge port 21 for discharging from the 20 can be formed. Preferably, by connecting the detachable warhead recovery container 50 to the discharge port 21, it is possible to conveniently recover the warhead (3) collected in the warhead recovery container (50).

The warhead refraction chamber 20 may also be made of a special wear resistant steel sheet having strength that can withstand the destructive force of the warhead 3, like the warhead induction chamber 10, and the sound insulating material 40 on its outer surface for blocking noise and vibration. Can be coated.

The impact absorption roller 30 is installed in the warhead refraction chamber 20 adjacent to the outlet 12 of the warhead induction chamber 10. The warhead 3, which is primarily absorbed to a certain extent while passing through the warhead induction chamber 10 and whose speed is reduced, exits the outlet 12 and hits the shock absorbing roller 30 secondarily.

As shown in FIG. 4, the shock absorbing roller 30 is rotatably installed, and in the illustrated embodiment, the shock absorbing roller 30 is rotatably installed by the shaft 31 and the bearing 32. have.

According to the application of the shock absorbing roller 30, when the warhead (3) collides with the shock absorbing roller (30) and its energy is transmitted, the shock absorbing roller (30) is rotated according to the impact position and angle and the warhead (3) As the direction of travel changes, the energy of the warhead 3 (advancing and rotational energy) is absorbed, so that the energy of the warhead is significantly reduced.

The warhead (3) introduced from the warhead induction chamber (10) into the warhead refractive chamber (20) hits the impact absorbing roller (30), and then strikes the inner wall of the warhead refractive chamber (20) after its rotation direction is changed. It safely rotates along the inner wall of the warhead refraction chamber 20, and in this process, the energy of the warhead 3 is completely absorbed and finally stopped.

As shown in FIG. 4, when the warhead refractive chamber 20 is spherical, the shock absorbing roller 30 may be formed in a spherical shape or a cylinder. As shown in FIG. 6, the warhead refractive chamber 20 is long. In the case of a cylindrical shape, the shock absorbing roller 30 may be formed in a long cylindrical shape.
