Definitions

  • the invention relates to a bullet trap according to the preamble of claim 1.
  • DE-PS 31 31 228.4 shows a bullet trap in which, behind a target surface, a plurality of vertically arranged plates are spaced apart in two rows in a row such that zigzag channels are formed between the plates of the two rows where the incoming projectiles swing back and forth until they are braked so far that they fall down onto the floor under the bullet trap.
  • DE-OS 32 12 781 another bullet trap emerges, in which a granulate bound by a binding agent to form a lump-like structure is arranged, the task of which is also to slow down the projectiles discharged into the granulate.
  • a problem with the known granular projectile catch is that disposal of the projectile catch is problematic is because the projectiles released into the bound granulate are held in it, that is to say are part of the bound granulate. This means that disposal can only take place by disposing of the bound granules together with the projectiles contained therein. This means that the amount of disposal incurred per operating period of projectile capture is relatively large. In addition, a separation of the bound granulate and the floors contained therein is hardly possible or only with extremely complex steps.
  • the object of the present invention is therefore to improve a bullet trap of the type mentioned in such a way that a much easier and better disposal is made possible.
  • the main advantage of the projectile trap according to the invention is that simple disposal of the projectile trap is possible.
  • the granulate and the braked projectiles contained therein are extremely simple and effective Are separable from each other. This has the consequence that the projectiles or projectile particles braked in the projectile trap can simply be recovered and disposed of or further processed, and at the same time the granules in the projectile trap can be used as a braking medium.
  • the operating costs of the bullet trap according to the invention are reduced to a very substantial extent because the granulate used as the braking medium can be reused and because only small amounts of disposal, namely the bullets braked in the bullet trap, are incurred.
  • projectile catch can be designed for any type of ammunition.
  • only the length of the bullet catch in the weft direction is adapted to the type of caliber used.
  • a length of approximately 400 mm is selected for handguns, while a projectile catch suitable for long weapons is approximately 800 mm long.
  • the bullet trap according to the invention can advantageously can be built in any size depending on the application.
  • the present granular projectile trap essentially has a preferably box-shaped container 1, which is on one, behind one Side arranged target surface has a recess 11 which is closed by a preferably disc-shaped medium 2 through which the projectiles fired at the target surface can pass.
  • the medium 2 is preferably a rubber plate. Due to the elasticity of the rubber material, the holes formed in the rubber sheet 2 when the projectiles penetrate close again automatically when the projectiles have passed through the rubber sheet 2.
  • the rubber plate 2 is preferably stretched in front of the recess 11 so that it closes the recess 11 like a wall.
  • the granulate 3 which is generally a granular, free-flowing soft material that is capable of closing the length L (FIG. 2) of the container 1 released into the container 1 by the rubber plate 2 slow down.
  • the granulate 3 preferably consists of granular rubber material, the grain size of which is, for example, about 6 mm and which is available on the market as a waste product.
  • the container 1 can have a removal opening, for example the tubular opening 4 in FIG. 1, and a filling opening (not shown in more detail), for example in the upper container wall.
  • the removed granules containing the projectile particles can be freed from the projectiles or projectile particles in a simple manner known per se. Procedures for this will be explained in more detail later.
  • the container is box-shaped, wherein the rubber plate 2 forms the front wall of the container 1 'and closes the opening 11' formed by the side walls, the upper wall and the lower wall.
  • the container On the side facing away from the rubber plate 2, the container is closed by a rear wall.
  • the lower wall of the container extends obliquely downwards from the lower end of the rear wall in the direction of the rubber plate 2, so that the lowest point of the container is approximately where the lower wall and the rubber plate 2 meet. In this area there is preferably a removal opening 4 'for the granulate.
  • a removal opening 4 "is preferably arranged there. 1 and 2 is also box-shaped, the lower wall of the container 1 being in the form of a funnel, the upper opening of which is molded onto the walls of the container and the lower end of which forms the outlet opening 4.
  • the outlet openings 4, 4 'or 4 are preferably each formed by a pipe socket attached to the container 1, 1', 1", which can be closed by a cover or the like.
  • the rubber plate 2 of the container 1, 1 ', 1 can be arranged behind a target surface or can even form the target surface.
  • the outer surface of the rubber plate 2 can be coated with a white material, so that it can serve as a projection surface for stationary or moving target images generated with the aid of a suitable projector.
  • the granules are removed from the container 1, 1 ', 1 "for disposal of the bombarded granules and carried out at a location separate from the projectile trap.
  • the removal opening 4 is connected via a valve 5 to the inlet 6 of a separating device 7, which has a first outlet, which is connected to a line 9, and a second outlet 8.
  • the granular granules 3 are separated from the projectile particles, the projectile particles being discharged via the outlet 8 and the granules being returned to the container 1 via the return line 9 and an opening 10 in a wall of the container 1.
  • the separating device 7 is such that it can suck the granules and the bullet trapping parts out of the container 1 via the opened valve 5, a separation being carried out in the separating device 7 due to the different weights of the granules 3 and the projectile particles such that the comparatively heavy projectile particles are fed to the outlet 8 and the comparatively light granules to the return line 9.
  • the separating device 7 can be a centrifuge device or a vacuum separator in which the parts sucked in via the opened valve 5 by a vacuum generated are separated in such a way that the heavier particles are fed to the outlet 8 and the lighter particles are sucked back via line 9 to container 1.
  • the corresponding vacuum pump can be provided either in the separating device 7 or at the opening 10 of the return line 9 in the container 1 or in the return line 9. However, it is also conceivable to reintroduce the granulate parts separated from the projectile particles in the separating device 7 into the container 1 under pressure via the return line 9.
  • the separation in the separation device 7 can also be carried out by the jet of a fan, which feeds the light particles to the return line 9 and allows the heavy particles to pass to the outlet 8. It is conceivable to use sensors that control the beam depending on the type of particles detected (granules or projectiles or projectile particles).
  • a large projectile area which may for example comprise 4x8 m, is formed by a container 1 "', the access opening or recess 11"' of which corresponds to the size of the projectile area.
  • a container 1 "' the access opening or recess 11"' of which corresponds to the size of the projectile area.
  • Each extraction point is connected via a valve 41, 42, 43 to a collecting line 9 ′′ for the removed granulate, which contains the projectiles and projectile particles.
  • the collecting line 9 ′ is connected to a separating device 7 ′, which has an outlet 8 ′ for the projectiles and projectile particles and a further outlet which is connected to a return line 9 'which is led into the interior of the container 1 "'. Since the provision of a rubber plate covering the large recess 11 "'is relatively complex, the recess 11"' is preferably covered by a plurality of rubber plates 2 'arranged next to one another, which either adjoin one another or can overlap in the manner shown.
  • Disposal of this projectile catch can advantageously be individually adapted to the areas of the projectile catch used more or less during a predetermined operating time, since the individual valves 41, 42, 43 are opened separately from one another depending on the respective load on the areas of the granules 3 assigned to them with projectile catch particles can be.
  • the walls of the container 1, 1 ', 1'',1''' are preferably made of steel. However, it is also conceivable that these walls at least partially by z. B. existing concrete walls are formed.
  • FIGS. 6 and 7 show a further development of the invention, in which the container 50 of the projectile catch can be set in motion by a device 51 in such a way that the contents of the container 50, that is to say the bombarded granulate, are set in motion to avoid clumping of the granules and to ensure that the bullets released into the granules are moved out of the main bullet area, so that collisions between bullets which have already slowed down in the granules and newly penetrating bullets are avoided.
  • the container 50 of the projectile catch can be set in motion by a device 51 in such a way that the contents of the container 50, that is to say the bombarded granulate, are set in motion to avoid clumping of the granules and to ensure that the bullets released into the granules are moved out of the main bullet area, so that collisions between bullets which have already slowed down in the granules and newly penetrating bullets are avoided.
  • the device 51 is designed such that it can rotate the container 50 about its longitudinal axis 54. During these rotations, clumping of the granules 51 'is prevented and, in addition, the projectiles or projectile particles located in the granules 51' are led out of the injection area located behind the injection opening 52.
