Description
Technical field
The invention belongs to forest extinguishing fields, and in particular to a kind of 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.And in fire
In the case where the non-communicating view of field, the function of long-range forest extinguishing cannot achieve.
Summary of the invention
The object of the present invention is to provide it is a kind of emit fire extinguisher bomb barrel, for emit fire extinguisher bomb and assign muzzle velocity and
Heading realizes the demand of long-range forest extinguishing in the scene of a fire in the case where non-communicating view.
The technical solution of the present invention is as follows: a kind of barrel for emitting fire extinguisher bomb, including sequentially connected muzzle brake 3, body
Pipe 1 and breech 2, it is characterised in that: further include clamping ring 4, nut 5, stop washer 6, screw 7, recoil collision block support arm 8, collision block
9, tooth 10, key 11, screw 12, screw 13 and washer 14 are stayed；Thorax is divided into coyote hole portion A, forcing cone portion B, rifling from the front to the back in barrel 1
Portion's C three parts, coyote hole portion are used to accommodate cylindrantherae, which tapers slightly；Forcing cone portion is made of two different conical sections of taper, bullet
After ball forces home, bearing band is caught on the biggish one section of forcing cone of taper, guarantees that bullet has correct initial position, taper is smaller
One section of forcing cone on rifling, be the initial part of rifling；The physical dimension of barrel 1 gradually becomes smaller from the front to the back, two sections of rear portion light
Sliding cylindrical portion is the guide part of barrel, and barrel is slid back and forth using this part along tubular reel cage with multiple into when in recoil；Big gun
Tail 2 is square structure, has the door bolt room stood to opening in the middle part of breech 2, for accommodating breech block, and moves up and down to provide for breech block and lead
Rail；Muzzle brake 3 is porous single air chamber structure.
The utility model has the advantages that the present invention utilize direct laying of fire function remote transmission extinguishing chemical, structure is reliable, guarantee bullet filling with
Transmitting cooperates when transmitting with high temperature, high pressure, high speed powder gases, for emitting fire extinguisher bomb and assigning muzzle velocity and flight side
To accurate compacting remote to the progress of the scene of a fire intensity of a fire is shortened from generation fire to the time for taking fire suppression measures, reduces the intensity of a fire
Sprawling.The function of long-range forest extinguishing is realized in the case where non-communicating view in the scene of a fire, is suitable for various medium caliber fire-extinguishing guns.

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 barrel for emitting fire extinguisher bomb, including sequentially connected muzzle brake 3, barrel 1 and breech
2, further include clamping ring 4, nut 5, stop washer 6, screw 7, recoil collision block support arm 8, collision block 9, stay tooth 10, key 11, screw 12,
Screw 13 and washer 14；
Thorax is divided into coyote hole portion A, forcing cone portion B, rifled gun C three parts from the front to the back in barrel 1, and coyote hole portion is used to accommodate medicine
Cylinder, for convenient for extracting cylindrantherae out, which is tapered slightly；Forcing cone portion 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, and guidance bullet is rotated clockwise to reach bullet stabilized flight institute when transmitting
The revolving speed needed.
The appearance of barrel 1 is to adapt to breech pressure varying dimensions gradually to become smaller from the front to the back, the smooth cylinder in two sections of rear portion
Portion E is the guide part of barrel, and barrel is slid back and forth using this part along tubular reel cage with multiple into when in recoil.1 tail end of barrel
Outer cylinder and breech 2 cooperate, and when installation, 1 tail end mirror surface D of barrel is bonded with breech mirror surface, and 11 anti-rotation of load key is then threaded into screw
12 is fixed.There are the screw thread and 7 mounting groove of backing-up screw of installation muzzle brake 3 in the front of barrel 1.
Breech 2 is square structure, for installing breech block, fixed semiautomatic plant, and connection barrel 1, recoil mechanism
(recoil brak, recuperator means).2 front of breech has screw thread to connect with clamping ring 4, and 1 breech face mirror surface of barrel is bonded simultaneously with 2 mirror surface of breech
With 11 anti-rotation of key.
There is the door bolt room stood to opening in the middle part of breech 2, for accommodating breech block, and is moved up and down for breech block and guide rail is provided.Breech 2
There is recoil brak mounting hole in front of top, there is recuperator means mounting hole in front of lower part, the top left rear side of breech 2, which has, places quadrant
Verifying bench.There are be used for artificial recoil combined hole at breech 2 rear portion.Semiautomatic plant is fixed on the right side of breech 2, there is breechblock in middle and upper part
Baffle mounting hole prevents from closing breechblock when fastening with a bolt or latch and rose position.2 left side front upper place of breech install recoil collision block support arm 8, with screw 13,
Washer 14 is fixed, and recoil collision block 9 is welded in collision block support arm 8 front in recoil, cooperates with recoil cuing scale, when shooting instruction recoil away from
From.
Muzzle brake 3 is porous single air chamber structure, for consuming part recoil energy, to reduce recoil length and to big gun
The active force of frame.Muzzle brake 3 is spun on 1 front end of barrel with left hand thread, and fixed with nut 5, stop washer 6 and screw 7；
There is " ten " word groove on its front end face, pasting cross hairs when for checking that sight line is synchronous with axis of the bore.
Clamping ring 4 is tubular construction, and inner wall smooth and 1 outer wall of barrel cooperate, and outer wall thread is connect with breech 2, when installation.
After the fastening in place of clamping ring 4, with staying, tooth 10 is locking.
A kind of barrel of transmitting fire extinguisher bomb of the invention, has been applied in the long-range forest fire-extinguishing system of our factory,
In material object shooting verification test, emit nearly 300 hair of fire extinguisher bomb altogether.The barrel ballistic performance is stablized, and structure is reliable, has more farsighted
The accuracy at target of distance is effectively reduced and closely puts out the larger intensity of a fire to harm brought by personnel, reduces casualties, mention
High fire-fighting efficiency reduces 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.
