Description

Projectile-forcing retreating device of projectile-forcing cannon

Technical Field

The utility model relates to a bullet extractor, in particular to a bullet extractor of a duro gun.

Background

In the process of one-time PLL05 type 120 mm self-propelled grenade live ammunition shooting, the forced ammunition (elliptic ammunition) which is not closed in the prior art is forced to eject and then is clamped in a gun bore, the simple mechanical processing and the ejection are difficult to realize, then the follow-up tool is used for advancing and ejecting the ammunition, before that, the PLL05 type 120 mm self-propelled grenade follow-up tool adopts a forward ejection rod for the forced ammunition ejection. After the phenomenon of forced ammunition jamming occurs, the front ammunition withdrawing rod is taken out and decomposed, the ammunition withdrawing pestle is combined with the first section of the ammunition withdrawing rod and extends into the bore from the muzzle, then the ammunition withdrawing pestle is combined section by section, finally the ammunition withdrawing pestle is contacted with the ammunition, and under the static combination, the tail part of the ammunition withdrawing rod is knocked by a big hammer and similar tools, so that the forced ammunition is withdrawn.

However, the existing bullet-withdrawing technology has the following defects: firstly, the time is consumed for the front ammunition withdrawing, the procedures of preparing a front ammunition withdrawing rod, decomposing the ammunition withdrawing rod, extending the ammunition withdrawing rod into a gun muzzle and the like are carried out, the danger degree is high, and the time is consumed for the operation of personnel; secondly, the cooperation of a plurality of people is needed for forward ammunition withdrawing, the cooperation of 2 people is needed for the muzzle, and the cooperation of at least 2 people is needed for the tail of the gun; thirdly, the danger coefficient is increased, the tail part of the ejection rod needs to be smashed by a tool in the conventional ejection mode to break the force of the blocking bullet, the dynamic acting force is a dynamic acting force, the instantaneous kinetic energy is large, and the relative danger coefficient is large when the force is exerted near the fuse; fourth, it is not in accordance with the battlefield requirement, during the battle, the PLL05 type 120 mm self-forcing grenade gun is located behind the front edge, the operation in the personnel gun is relatively safe, but the forward-retreating mode, the personnel must go outside the gun to operate, which is not in accordance with the actual battle requirement. Therefore, the technology of developing the backward projectile of the PLL05 type 120 mm self-forcing grenade projectile has important significance.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a compel duro big gun to force bullet recoil bullet ware to solve prior art and waste time and energy, the security is poor, be not conform to the problem of actual combat requirement.

The utility model discloses a realize like this: the utility model provides a compel duro gun to compel bullet recoil bullet ware, it is fixed with the front pawl fixed disk at the end of screw thread dowel steel, is equipped with a plurality of front pawls in the quotation of front pawl fixed disk, and the end of every front pawl all is equipped with the hook portion that is used for catching compel bullet fin, and the spiro union has the handle fixed disk on screw thread dowel steel, is being equipped with a plurality of handles on holding the fixed disk, is being equipped with the baffle that moves back between holding fixed disk and front pawl fixed disk, the length of baffle that moves back slightly is greater than the bore external diameter, is equipped with the cross-under hole at the center of baffle that moves back, and the baffle that moves back cup joints on screw thread dowel steel through the cross.

The four front claws are arranged at positions matched with the position of the projectile forcing tail wing.

The hook part of the front claw is in a right-angle return bending type.

The front side of the handle fixing disc is a plane, and the rear side of the handle fixing disc is a curved surface.

The handle is three, and three handle is radial arrangement on the trailing flank of handle fixed disk.

The utility model discloses all technical problems that exist among the prior art have effectively been solved to the PLL05 formula 120 millimeter by oneself compel duro cannon compel bullet recoil bullet ware of development, have save time, laborsaving, factor of safety is high, accord with the advantage of battlefield safety requirement.

The utility model discloses the bullet that moves back before the muzzle that will compel the bullet improves and moves back the bullet in the gun carriage to improve dynamic action power into static action power, improve factor of safety. Particularly, compared with the forward bullet withdrawing technology, the utility model reduces the number of preparation tools before operation, reduces the preparation procedures and greatly shortens the operation time; secondly, compared with the forward bullet withdrawing technology, the utility model reduces the number of operators, and reduces the operation from 4 people to 2 people; thirdly, compared with the forward ammunition withdrawing technology, the utility model reduces the danger coefficient, converts the dynamic acting force of the forward ammunition withdrawing operation into the static acting force, avoids the force application operation near the fuse and avoids the accident caused by the overlarge peak value of the dynamic acting force; fourth, compare the technique of moving back before, the utility model discloses convert the operation outside the personnel big gun into the big gun in the operation, more accord with the battlefield requirement, the operation improves battlefield survival rate greatly in the personnel big gun, further ensures that the battle field power is preserved.

Fig. 3 is a schematic structural view of the projectile tail wing of the present invention.

In the figure: 1. the device comprises a threaded dowel bar, 2, a front claw fixing disc, 3, a front claw, 4, a forced spring tail wing, 5, a handle fixing disc, 6, a handle, 7 and a spring withdrawing baffle.

Detailed Description

As shown in figures 1-3, the utility model discloses a structure is fixed with front claw fixed disk 2 at the end of screw thread dowel steel 1, and front claw fixed disk 2 rear side is by a sleeve structure connection screw thread dowel steel 1. Four front claws 3 are arranged on the disc surface of the front claw fixing disc 2, and the arrangement positions of the four front claws 3 are matched with the positions of the forced missile tail wings 4. The tail end of each front claw 3 is provided with a hook part used for hooking a projectile empennage, and the hook part is of a right-angle return bend type or a reversed L type. The screw thread dowel bar 1 is screwed with a handle fixing disk 5, the front side of the handle fixing disk 5 is a plane, and the rear side of the handle fixing disk 5 is a curved surface. Three grips 6 are arranged on the handle fixing disk 5, and the three grips 6 are radially arranged on the rear side surface of the handle fixing disk 5. The handle 6 is rotated to enable the handle fixing disc to rotate on the thread dowel bar 1, and the handle fixing disc can move relatively along the thread dowel bar by utilizing the static force application of the thread machine of the thread dowel bar. A bullet withdrawing baffle 7 is arranged between the holding handle fixing disk 5 and the front claw fixing disk 2, the length of the bullet withdrawing baffle 7 is slightly larger than the outer diameter of the bore, a through hole is arranged in the center of the bullet withdrawing baffle 7, and the bullet withdrawing baffle 7 is sleeved on the threaded dowel bar 1 through the through hole. When the projectile is retreated, the projectile retreating baffle ensures that the positions of the gun bore, the projectile retreating baffle 7 and the grip fixing disc 5 are relatively static in the longitudinal direction, and the threaded dowel bar 1 moves backwards relatively, so that the projectile is taken out.

The utility model discloses when using, stretch into the bore with fore-stock fixed disk 2 to catch on with fore-stock 3 and compel bullet tail wing 4, simultaneously, move back bullet baffle 7 card at the bore afterbody, rotatory handle fixed disk 5 drives fore-stock fixed disk 2 rearward movement with 1 rearward movement of screw thread dowel steel, thereby through the even atress of fin, will compel the bullet to pull backward, withdraw from the ammunition.
