Description

Technical Field

[0001] This utility model relates to the field of ammunition processing equipment technology, specifically to a portable bullet destruction tool. Background Technology

[0002] As a special type of hazardous material, bullets must be handled scientifically and safely when they expire, become obsolete, or need to be destroyed to avoid accidents. Currently, the following two methods are mainly used for the destruction of bullets of varying quantities, but both have significant limitations.

[0003] For the destruction of small batches of ammunition, the manual striking method is commonly used. The procedure is roughly as follows: using hand tools such as hammers and pliers, the bullet is first forcibly pulled out, then the propellant is gently tapped out, and finally the primer is ignited by striking. Its advantage is its simplicity, requiring no complex equipment, and applicability in most situations. However, this method has extremely poor safety; personnel safety relies heavily on wearing protective gear. Improper operation can easily lead to accidental discharge, casing explosion, and other dangers, posing a serious threat to the lives of the operators. Furthermore, manual operation is inefficient, time-consuming, labor-intensive, and cannot guarantee complete destruction; it also has poor compatibility with different calibers of ammunition.

[0004] For the destruction of large quantities of ammunition, the furnace method is commonly used. This involves pouring the bullets into a large, enclosed furnace and melting them at high temperatures to achieve the purpose of destruction. The advantage of this method is its suitability for large-scale processing and high destruction efficiency. However, its disadvantages are also significant: firstly, it requires large furnace equipment and specific sites, resulting in high equipment and condition requirements and high costs; secondly, this method is only suitable for centralized destruction and is completely unsuitable for grassroots units, field operations, or scenarios requiring the immediate destruction of small quantities of ammunition, exhibiting extremely poor flexibility.

[0005] In practice, grassroots units, public security departments, and military training grounds frequently encounter situations requiring the destruction of small batches or scattered ammunition. The two existing destruction methods cannot meet their requirements for safety, convenience, and efficiency. Therefore, developing a portable tool that balances safety, portability, and adaptability, suitable for the destruction of various types of units and different quantities of ammunition, has become an urgent problem to be solved. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned problems and provide a portable bullet disposal tool. To achieve the above objective, this utility model adopts the following technical solution:

[0007] A portable bullet disposal tool includes a bullet clamp, a cartridge case clamp, a crank cam mechanism, a primer firing device, and a base plate. The cartridge case clamp is mounted on the crank cam mechanism. The bullet clamp clamps the bullet head, and the cartridge case clamp clamps the bullet casing. The cartridge case clamp has upright plates on both sides, and the cartridge case clamp is rotatably connected to the upright plates. The primer firing device is located at the rear of the cartridge case clamp. The crank cam mechanism, upright plates, and primer firing device are fixed to the base plate.

[0008] The crank-cam mechanism drives the bullet holder to pull out the bullet head, rotates the cartridge case holder to pour out the propellant, and releases the primer firing device to ignite the bullet primer.

[0009] As an improvement, the projectile clamp includes a first adjustable dimension chuck, with first lugs on both sides of the first adjustable dimension chuck, a plurality of first dimension claws on the first adjustable dimension chuck, and a first adjusting bolt on the first adjustable dimension chuck. The first dimension claws clamp the projectile and move radially along the projectile clamp. The first lugs are connected to a crank cam mechanism.

[0010] As an improvement, the crank-cam mechanism includes a first handwheel, a transmission guide wheel, a cam guide rail, a cam structure, a crank linkage mechanism, a sliding block, and a sliding guide rail. The sliding block is slidably mounted on the sliding guide rail. First connecting rods are provided on both sides of the sliding block. The front end of the first connecting rod is connected to a first lug. The rear end of the sliding block is connected to the top of the crank linkage mechanism. A rolling bearing is provided at the bottom of the crank linkage mechanism. The rolling bearing is slidably connected to the cam structure. The first handwheel is connected to the transmission guide wheel. A second connecting rod is provided between the transmission guide wheel and the cam structure. The cam structure is slidably mounted on the cam guide rail. The rotation of the first handwheel is converted into the axial movement of the sliding block along the sliding guide rail.

[0011] As an improvement, the cartridge case clamp includes a second adjustable dimension chuck, with rotating shafts on both sides of the second adjustable dimension chuck. A limiting mechanism is provided at the outer end of the rotating shafts, which restricts the cartridge case clamp from moving along the axial direction of the rotating shafts. A handle is provided on the limiting mechanism. A plurality of second dimension claws are provided on the second adjustable dimension chuck, and a second adjusting bolt is provided on the second adjustable dimension chuck. The second dimension claws clamp the cartridge case.

[0012] As an improvement, the top of the upright plate is provided with a groove, the rotating shaft is rotatably connected to the groove, the top two ends of the groove are provided with limit pins, the limit pins are provided with limit blocks, and the limit mechanism is provided with a positioning lock.

[0013] As an improvement, the primer firing device includes a firing device base, a lead screw, a second handwheel, and a dovetail adjuster. The firing device base is fixed to the base plate, the lead screw is disposed in the firing device base, the second handwheel is disposed at one end of the lead screw, the dovetail adjuster is disposed on the middle of the lead screw, the top of the dovetail adjuster is provided with a firing device clamp, the firing device clamp is provided with a semi-automatic primer firing mechanism, and the firing device clamp is provided with locking screws on both sides.

[0014] As an improvement, the base plate is provided with a segmented protective cover, which includes four protective shells. The protective shells are connected to the base plate through dovetail grooves. The four protective shells are opened step by step by pushing and pulling. Each protective shell is provided with a handle.

[0015] The advantages of this utility model are:

[0016] 1. This utility model significantly improves safety. The tool is equipped with a segmented protective cover, which forms a five-dimensional protective layer when the primer is fired. This effectively blocks projectile fragments, gunpowder residue, and other debris, preventing injury to the operator and solving the problem of poor safety associated with manual firing. Simultaneously, the design of the clamps and limiting mechanisms ensures the stability of the bullet during disposal, reducing the possibility of accidents. The use of a semi-automatic primer firing machine avoids personnel directly striking the primer with the tool, further improving operational safety.

[0017] 2. This utility model is convenient and efficient to operate. It achieves mechanized extraction of the projectile through a crank-cam mechanism, which is more labor-saving and faster than manual extraction, significantly improving operational efficiency. The cartridge case holder can rotate flexibly for easy dispensing of propellant, and the position of the primer igniter can be precisely adjusted to ensure accurate and reliable primer firing. The entire operation process is simple and easy to understand, requiring no professional skills to master quickly, thus solving the problem of low efficiency in manual operation.

[0018] 3. This utility model has strong adaptability. Both the bullet clamp and the cartridge case clamp adopt adjustable chucks, which can be adjusted by adjusting the bolts to accommodate bullets of different calibers, making it suitable for the destruction of various types of bullets. The tool has a compact overall structure, small size, and light weight, making it easy to carry and transport. It is suitable for various scenarios such as grassroots units and field operations, making up for the shortcomings of the furnace method in being unsuitable for small-batch, decentralized destruction.

[0044] The present invention will be described in detail below through specific embodiments to enable a better understanding of the present invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0045] Example 1

[0046] This embodiment discloses a portable bullet destruction tool.

[0047] like Figures 1 to 10 As shown, this embodiment includes a bullet holder 100, a cartridge case holder 200, a crank cam mechanism 300, a primer firing device 400, a base plate 500, and a segmented protective cover 600. The components work together to complete the disassembly and disposal process of the bullet.

[0048] Base plate 500: As the basic support component of the entire tool, all mechanisms are fixed on the base plate 500, ensuring the overall stability and structural strength of the tool.

[0049] Bullet clamp 100: Used to clamp bullet heads for subsequent extraction. It includes a first adjustable dimensional chuck 101, with first lugs 102 on both sides for connection to a crank cam mechanism 300. The chuck has several first dimensional claws 103 and first adjusting bolts 104. By turning the first adjusting bolts 104, the first dimensional claws 103 can be driven to move synchronously radially along the bullet clamp 100, thereby adapting to bullets of different diameters and firmly clamping the bullet heads to ensure that slippage does not occur during bullet extraction.

[0050] The cartridge case clamp 200 is used to clamp cartridge cases. Its structure is similar to the bullet clamp 100, including a second adjustable chuck 202. Rotary shafts 203 are located on both sides of the chuck, and a limiting mechanism 204 is located at the outer end of each shaft 203. The limiting mechanism 204 restricts the axial movement of the cartridge case clamp 200 along the shaft 203, preventing axial displacement during operation. A handle 205 is provided on the limiting mechanism 204 for easy rotation of the cartridge case clamp 200. The chuck has several second-dimensional claws 206 and a second adjusting bolt 207. By adjusting the second adjusting bolt 207, the second-dimensional claws 206 can clamp cartridge cases of different calibers. Upright plates 201 are located on both sides of the cartridge case clamp 200. A groove 208 is located on the top of each upright plate 201. The shaft 203 is rotatably connected to the groove 208, allowing the cartridge case clamp 200 to rotate around the shaft 203. The top two ends of the groove 208 are provided with limit pins 209, the limit pins 209 are provided with limit blocks 210, and the limit mechanism 204 is provided with positioning locks 211, which are used to fix the rotation angle of the cartridge case clamp 200 to ensure that the cartridge case is in a stable state when the cartridge is pulled out and the primer is fired.

[0051] Crank-cam mechanism 300: Provides power to drive the bullet holder 100 to extract the bullet. It includes a first handwheel 301, a transmission guide wheel 302, a cam guide rail 303, a cam structure 304, a crank-connecting mechanism 305, a sliding block 306, and a sliding guide rail 307. The sliding block 306 is slidably mounted on the sliding guide rail 307. First connecting rods 309 are provided on both sides of the sliding block 306. The front end of the first connecting rod 309 is connected to the first lug 102 of the bullet holder 100, and the rear end of the sliding block 306 is connected to the top of the crank-connecting mechanism 305. A rolling bearing 308 is provided at the bottom of the crank-connecting mechanism 305, and the rolling bearing 308 is slidably connected to the cam structure 304. The first handwheel 301 is connected to the transmission guide wheel 302. A second connecting rod 310 is provided between the transmission guide wheel 302 and the cam structure 304. The cam structure 304 is slidably mounted on the cam guide rail 303. When the first handwheel 301 is turned, the cam structure 304 is driven to slide on the cam guide rail 303 via the transmission guide wheel 302 and the second connecting rod 310. The cam structure 304 pushes the rolling bearing 308 to move, which in turn causes the crank linkage mechanism 305 to drive the sliding block 306 to move axially along the sliding guide rail 307, ultimately realizing the linear movement of the bullet clamp 100 and pulling the bullet out of the cartridge case.

[0052] Primer igniter 400: Used to fire the bullet primer, including a igniter base 401, a lead screw 402, a second handwheel 403, and a dovetail adjuster 404. The igniter base 401 is fixed to the base plate 500. The lead screw 402 is located in the igniter base 401. The second handwheel 403 is located at one end of the lead screw 402. The dovetail adjuster 404 is located in the middle of the lead screw 402. A igniter clamp 405 is located on the top of the dovetail adjuster 404, and a semi-automatic primer firing mechanism 406 is mounted on the clamp for firing the primer. Locking screws 407 are located on both sides of the igniter clamp 405 to fix the position of the semi-automatic primer firing mechanism 406. By rotating the second handwheel 403, the lead screw 402 can be driven to rotate, which drives the dovetail adjuster 404 to move back and forth, thereby adjusting the relative position of the semi-automatic primer firing mechanism 406 and the bullet primer to ensure accurate firing.

[0053] Segmented protective cover 600: Provides safety protection during operation, including four protective shells 601. The protective shells 601 are connected to the base plate 500 via dovetail grooves. The four protective shells 601 unfold sequentially by pushing and pulling, forming a five-dimensional protective layer when the primer is fired, effectively blocking potential debris and impact forces. The protective shells 601 are equipped with handles 602 for easy operation, and the protective cover can be removed step by step to adapt to different operational needs.

[0054] Workflow

[0055] The bullet is placed between the bullet clamp 100 and the cartridge case clamp 200. By adjusting the first adjusting bolt 104 and the second adjusting bolt 207, the bullet clamp 100 and the cartridge case clamp 200 clamp the bullet and the cartridge case respectively.

[0056] Turning the first handwheel 301 causes the sliding block 306 to move along the sliding guide rail 307 via the crank cam mechanism 300, which in turn causes the bullet clamp 100 to move outward, pulling the bullet out of the cartridge case.

[0057] Loosen the positioning lock 211 of the cartridge case holder 200, turn the handle 205 to tilt the cartridge case holder 200, and pour out the propellant.

[0058] Rotate the cartridge case holder 200 back to the horizontal position and fix it with the positioning lock 211. Adjust the position of the primer firing device 400 so that the semi-automatic primer firing mechanism 406 is aligned with the cartridge primer.

[0059] Deploy the segmented protective cover 600, pull the semi-automatic primer firing mechanism 406 to fire the primer, and complete the destruction of the bullet.

[0060] The specific embodiments of this utility model have been described in detail above, but they are merely examples, and this utility model is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model should be covered within the scope of this utility model.
