Abstract
The invention discloses a kind of medium caliber rifle barrel for emitting fire extinguisher bomb, thorax is divided into coyote hole portion, forcing cone portion, rifled gun three parts from the front to the back in barrel, and coyote hole portion is used to accommodate cylindrantherae, which tapers slightly；Forcing cone portion is made of two different conical sections of taper, and after bullet forces home, bearing band is caught on the biggish one section of forcing cone of taper, and the lesser one section of forcing cone of taper is the initial part of rifling on rifling, and there is a plurality of dextrorotation mixing degree of twining rifling in rifle portion；The appearance of barrel is to adapt to breech pressure varying dimensions gradually to become smaller from the front to the back, and the smooth cylindrical portion in two sections of rear portion is and reel cage engaging portion.Structure of the invention is reliable, intensity meets requirement, guarantee bullet filling and transmitting, cooperate when transmitting with high temperature, high pressure, high speed powder gases, assign bullet stable initial velocity and heading, and bullet is made to rotate, it is advantageously implemented the remote accurate hit scene of a fire and carries out long-range forest extinguishing, be suitable for various medium caliber fire-extinguishing guns.
Description
Technical field
The invention belongs to forest extinguishing fields, and in particular to a kind of medium caliber rifle barrel for emitting fire extinguisher bomb.
Background technique
Forest fire is sudden strong, freely spreads and extends in forest land, and over time, the intensity of a fire constantly enhances,
Burnt area increases, and since forest zone transportation condition is poor, large-scale fire-fighting equipment is difficult to arrive at, and individual soldier's fire distinguisher is due to safety
Factor, when fire spreading, are difficult to closely sue and labour, and fighting difficulty is doubled and redoubled.Existing means are often robbed in the fire spread stage
Isolation strip is dug, closely takes pony material to put out a fire after preventing intensity of a fire range continuous enlargement, the intensity of a fire from weakening.For just
Lack in the intensity of a fire of gesture for occurring or have become sprawling and effective actively suppress or eliminate means.
Summary of the invention
The object of the present invention is to provide a kind of medium caliber rifle barrels for emitting fire extinguisher bomb, meet the need of long-range forest extinguishing
It asks, applies to long-range forest extinguishing big gun, distance transmission fire extinguisher bomb simultaneously accurately hits the scene of a fire.
The technical solution of the present invention is as follows: a kind of medium caliber rifle barrel for emitting fire extinguisher bomb, it is characterised in that: thorax in barrel
It is divided into coyote hole portion 1, forcing cone portion 2,3 three parts of rifled gun from the front to the back, coyote hole portion 1 is used to accommodate cylindrantherae, which tapers slightly；Slope
Thorax 2 is made of two different conical sections of taper, and after bullet forces home, bearing band is caught in the biggish one section of forcing cone of taper
On, the lesser one section of forcing cone of taper is the initial part of rifling on rifling, and there is a plurality of dextrorotation mixing degree of twining rifling in rifle portion 3；Body
The appearance of pipe is to adapt to breech pressure varying dimensions gradually to become smaller from the front to the back, and the smooth cylindrical portion in two sections of rear portion is and reel cage knot
Conjunction portion 5.
The utility model has the advantages that structure of the invention is reliable, intensity meets requirement, guarantees bullet filling and transmitting, when transmitting with
High temperature, high pressure, the cooperation of high speed powder gases, assign bullet stable initial velocity and heading, and bullet is made to rotate, have
Conducive to the long-range forest extinguishing of remote accurate hit scene of a fire progress is realized, it is suitable for various medium caliber fire-extinguishing guns.
Detailed description of the invention
Fig. 1 barrel configuration schematic diagram of the present invention；
Fig. 2 is the cross-sectional view of Fig. 1；
Wherein: 1- coyote hole portion；2- forcing cone portion；3- rifle portion；4- barrel mirror surface；5- and reel cage engaging portion；6- gun muzzle system is moved back
Device installs screw thread；7- muzzle brake fastening screw mounting groove.
Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, a specific embodiment of the invention is made further detailed
Thin description.
The present invention provides a kind of medium caliber rifle barrel for emitting fire extinguisher bomb, which is provided with coyote hole portion 1, forcing cone portion 2, rifle
Portion 3, barrel mirror surface 4 install screw thread 6 and muzzle brake fastening screw mounting groove 7 with reel cage engaging portion 5, muzzle brake；
Thorax is divided into coyote hole portion 1, forcing cone portion 2,3 three parts of rifled gun from the front to the back in barrel, and coyote hole portion 1 is used to accommodate medicine
Cylinder, for convenient for extracting cylindrantherae out, which is tapered slightly；Forcing cone portion 2 is made of two different conical sections of taper, and bullet forces home
Afterwards, bearing band is caught on the biggish one section of forcing cone of taper, guarantees that bullet has correct initial position, the lesser one section of forcing cone of taper
It is the initial part of rifling on rifling, its effect is that in transmitting, guidance bearing band squeezes into rifling, and slows down the mill of initial part
Damage；There is a plurality of dextrorotation mixing degree of a twining rifling in rifle portion 3, and guidance bullet is rotated clockwise to reach bullet stabilized flight institute when transmitting
The revolving speed needed.The appearance of barrel is to adapt to breech pressure varying dimensions gradually to become smaller from the front to the back, the smooth circle in two sections of rear end
Column portion is slid back and forth into when using this part along tubular reel cage in recoil with multiple with reel cage engaging portion 5, barrel.Barrel tail end
Outer surface and breech cooperate, and when installation, barrel mirror surface 4 is bonded with breech mirror surface.The front of barrel has muzzle brake to install spiral shell
Line 6 and muzzle brake fastening screw mounting groove 7 are packed into fastening screw with locking after screwing when installing muzzle brake.
A kind of medium caliber rifle barrel of transmitting fire extinguisher bomb of the invention has obtained in the long-range forest extinguishing big gun of our factory
Using in material object shooting verification test, transmitting fire extinguisher bomb nearly 300 is sent out altogether.The barrel configuration is reliable, and intensity meets use and wants
It asks, is effectively reduced and closely puts out the larger intensity of a fire to harm brought by personnel, reduce casualties, improve fire-fighting efficiency,
Reduce fire extinguishing cost.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
