Description
Technical field
The present invention relates to drop fire mortar design and manufacturing technology field, more particularly to a kind of mortar emitter.
Background technology
As shown in figure 1, traditional mortar, shell is loaded at gun muzzle, then shell relies on self gravitation in body
Glided in pipe and hit bottom firing pin and realize and be under fire, the gas that shell transmitting is produced is discharged from gun muzzle.Big gun during to make shell glide
The gas being extruded in thorax smoothly flows out and does not influence the gliding speed of shell, between must just being left between shell and bore wall
Gap, that is to say, that shell diameter is less than barrel internal diameter, this is gun muzzle filling necessary condition of shell.
Air below shell need to be between shell and bore wall gap discharge upwards, so gun muzzle filling mortar big gun
Bullet is snapped down to breech percussion and needs the regular hour from being loaded into, and reduces the firing rate of mortar, this time and shell and thorax
Gap length between wall is directly proportional.
Due to the presence in gap, powder gases also will largely leak when shell is launched, and its amount of releasing is total up to powder gases
The 10-15% of amount, its result causes gun pressure to reduce, and causes shell muzzle velocity to reduce.Gap is bigger, and the powder gases amount of releasing is got over
Greatly, the capacity usage ratio of propellant is lower.
The presence in gap also have impact on centering of the shell in thorax so that the shell after percussion can be sent out when being moved along barrel
It is raw to swing, and the powder gases amount of leakage of every hair bullet is inconsistent, causes initial velocity to spread, so as to cause shell fire accuracy to drop
It is low.
In summary, between shell and bore wall gap is big, and the firing rate of shell is improved, but the reduction of shell initial velocity, shooting essence
Degree reduction；Gap between shell and bore wall is small, and shell initial velocity is improved, fire accuracy is improved, but the firing rate reduction of mortar, very
To probably due to shell gliding speed not enough, causes firing power not enough and causes misfire.
The content of the invention
Based on this, the invention reside in the defect for overcoming prior art there is provided a kind of mortar emitter, it can improve urgent
Hit the initial velocity, firing rate and fire accuracy of big gun shell.
Its technical scheme is as follows：
A kind of mortar emitter, including breech, elastic component, closeouts and the tubular barrel with bore, it is described
Breech be arranged on barrel one end, and the breech be provided be located at bore in firing pin, the closeouts include axle sleeve and
The convex shoulder on the outside of axle sleeve is arranged on, the axle sleeve is set in outside firing pin, and the first end of the elastic component is connected in closeouts, the
Two ends are connected on breech, the breech be provided with least one first row stomata, when the elastic component in a state of nature when,
The first row stomata is connected with bore；When the elastic component is compressed, the convex shoulder blocks first row stomata.
In one of the embodiments, installation cavity is provided with the breech, the axle sleeve is arranged in the installation cavity, described
The first end of elastic component is connected on axle sleeve, and the second end is connected on the bottom wall of installation cavity.
In one of the embodiments, the bottom of the axle sleeve is provided with elastic component positioning hole, the first end of the elastic component
It is inlaid in the elastic component positioning hole.
In one of the embodiments, provided with the shoulder hole matched with firing pin in the axle sleeve, the shoulder hole has step
Face, the firing pin passes through and is also arranged with what is matched with the step surface outside the bottom that installation cavity is fixed on after shoulder hole, the firing pin
Locating part.
In one of the embodiments, the second row stomata connected with installation cavity, described second are additionally provided with the breech
Steam vent is at least one.
In one of the embodiments, the mortar emitter also include swollen tire, the swollen tire be set in axle sleeve and
Between firing pin.
In one of the embodiments, the contact surface of the convex shoulder and breech is circular conical surface.
In one of the embodiments, the elastic component is spring.
In one of the embodiments, the convex shoulder, which is provided with, is used for the location division that shell is positioned.
In one of the embodiments, the breech is detachably connected with barrel by screw thread.
The advantage or principle to preceding solution are illustrated below：
At least one first row stomata is offered at above-mentioned mortar emitter, breech, in filling, shell slips into big gun
In thorax, now in a state of nature, first row stomata and bore keep connecting elastic component, and the air being extruded in bore is from the
Smoothly discharged in one steam vent so that the more traditional mortar of shell gliding speed is fast；When shell slips down to bottom, shell hits envelope
Blocking piece, moves down convex shoulder, and elastic component is compressed, and now first row stomata is blocked, while shell is mutually touched with firing pin, fires big gun
The basic pencil fire in a stove before fuel is added of bullet, ignite gunpowder.When shell goes out bore, on the one hand powder gas promote shell motion, another invention
Closeouts are acted on, further such that convex shoulder is brought into close contact with breech and blocks first row stomata, prevent powder gas from leaking.When
Shell is flown out after barrel, and the gas pressure in bore is reduced rapidly, and elastic component returns to reset condition, first row stomata again with
Bore is connected, and completes once transmitting circulation.The mortar emitter, can guarantee that mortar projectile reliably glides, and air is from big gun
On the premise of first row stomata discharge in tail, the barrel internal diameter of small gap can be used, thus shell initial velocity, increase can be improved
Range, simultaneously effective improves fire accuracy.

Stomata 22 is at least one, and (second row stomata 22 is two in the present embodiment, and two second row stomatas 22 are positioned close to bullet
At the position of property part).When shell slips into bore, the air being extruded can be simultaneously at first row stomata 20 and second row stomata 22
The gliding speed of discharge, further increase shell.
It is preferred that, the mortar emitter described in the present embodiment also includes swollen tire 6, and the swollen tire 6 is arranged on axle sleeve 40
At position between firing pin 5.After shell percussion by the gaseous-pressure of gunpowder the elastic deformation of radial direction is occurred for swollen tire 6, from
And block shoulder hole 401, it is to avoid powder gas leak at second row stomata 22, while also avoiding elastic component 3 from being fired by gunpowder
Gas ablation.
As shown in figure 3, the contact surface of the convex shoulder 41 and breech 2 is circular conical surface, gas discharge is smooth, and is hit in shell
After hair convex shoulder 41 is fitted closely with breech 2, the sealing effectiveness of first row stomata 20 is more preferably.In the present embodiment, the bullet
Property part 3 be spring, spring is standard component, durable reliable and replacement convenient, in other embodiments, can also be used such as with bullet
Sleeve of property etc. is used as elastic component 3.
As shown in Figure 4,5, the convex shoulder 41, which is provided with, is used to the location division 410 that shell is positioned, make big gun by location division 410
Bullet is effectively contacted with closeouts 4, contributes to shell to promote closeouts 4.The breech 2 is detachably connected with barrel 1 by screw thread,
Safeguard and renewal part is more convenient.Due to being improved only for mortar emitter, thus the shell of mortar, gun carriage,
Bottom metal plate, sighting device and annex etc. need not be changed, and can be used directly.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and it describes more specific and detailed, but simultaneously
