Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a smoke grenade ejection tube that first ejects smoke and then ejects a smoke bomb, and the present invention relates to a smoke grenade ejection tube that first ejects smoke and then ejects a smoke bomb, and the present invention relates to both the smoke ejected from the ejection tube and the smoke drawn from the smoke bomb ejected from the ejection tube. Or, to provide a smoke grenade ejection tube that allows smoke to be visually recognized by at least one of them, has extremely high visibility, is therefore ideal as a mock gun for defense training, and has a simple structure and can be manufactured at low cost. This is what I am trying to do.

The firing of artillery shells during field training, which is carried out to develop the actual combat skills of soldiers or to test the results of operations, is based on the assumption that, for example, smoke is emitted from a smoke bomb and that the smoke actually causes the shell to be fired. This is done by assuming the impact on the enemy side of firing a shell.

However, the smoke emitted by a smoke canister does not necessarily rise high into the sky due to the terrain and weather where the smoke canister is installed, for example because its rise is blocked by trees, and therefore it may not be visible from a distance. There is.

In addition, since the smoke from a smoke canister is simply emitted from the installation bullet, it is not possible to determine the trajectory of the bullet that was supposed to have been fired depending on the smoke from the smoke canister, so training using a smoke canister is not practical. You can't expect big results unless you have a goal.

For this reason, training is sometimes conducted in which smoke bombs are fired and the trajectory of the shell can be determined by the smoke emitted by the smoke bombs.

However, the smoke drawn by a smoke bomb as it flies through the air at high speed tends to be thinner than the smoke emitted from a smoke bomb that is in a fixed position, and this, combined with weather conditions, can make it extremely difficult to see. There is.

In addition, the smoke from a smoke bomb does not rise into the sky like the smoke emitted from a smoke bomb, so even if it is possible to understand part of the trajectory, it will not reach the firing point of the shell. It may be impossible to understand.

In this way, there are advantages and disadvantages to both the training method of using the smoke emitted by a smoke bomb to determine the firing of an artillery shell, and the training method of using the smoke from a smoke bomb to determine the firing and trajectory of an artillery shell. It was difficult for those inspecting training results to accurately grasp the training situation or training results.

Therefore, the present invention has a simple structure that first ejects smoke, then ejects a smoke bomb, and can predict the ejection, ejection location, and trajectory of the bullet based on both the smoke ejected from the ejection tube and the trailing smoke of the smoke bomb. The purpose of this project is to provide a new smoke grenade ejection tube that can be manufactured at a low cost using A smoke bomb having a fuse whose tip is introduced into the propellant chamber is inserted into the open end side of the ejection tube body of the chamber, and a smoke powder is filled into the open end side of the smoke bomb insertion part. A smoke chamber is formed, and an ignition part is provided on the outside of the injection tube main body, and a fuse is provided to guide the fire from the ignition part to the smoke chamber, and a fuse is formed longer than the fuse to lead the fire from the ignition part to the above. It is characterized by being provided with a fuse that leads to the propellant chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The smoke grenade ejection tube of the present invention will be explained below according to the embodiments shown in the accompanying drawings.

1 shows an example of the implementation of the smoke grenade ejection tube of the present invention, and the smoke grenade ejection tube 1 includes a bottomed cylindrical ejection tube body 2, a propellant chamber 3 provided therein, and a smoke grenade 4. , smoke chamber 5,
Furthermore, it consists of fuse wires 7 and 8 that share one ignition part 6 on the outside of the injection cylinder main body 2.

The injection cylinder main body 2 is a cylindrical body with a bottom made of metal such as iron, and its opening is closed by attaching a cover plate 9 made of, for example, cardboard or the like.

The propellant chamber 3 is formed between the bottom 10 of the injection tube body 2 and a partition plate 11 mounted slightly above the bottom 10, and is exposed to the outside through a fuse hole 12 penetrated through the side surface of the injection tube body 2. It is connected with

Inside the propellant chamber 3 is a propellant 13 made of, for example, black powder.
is filled.

The smoke bomb 4 is a bottomed cylindrical body 16 made of aluminum or tinplate, etc., and has a fast-firing wire insertion hole 15 in the bottom 14;
A colossus 17 made of a gypsum filling provided at the inner bottom of the bottomed cylinder 16, a red smoke medicine 18 filled at the open end side of the bottomed cylinder of the coloss 17, and a filling part of the red smoke medicine 18. It consists of a fast-firing wire 20 inserted through a fast-firing wire insertion hole 19 provided in the coros 17 and a fast-firing wire insertion hole 15 provided in the bottom part 14 and led out to the outside, and the opening end of the injection cylinder main body of the propellant chamber 3. It is inserted on the side.

The colos 17 is provided so that the smoke bomb 4 can effectively receive the explosive force when the propellant 13 in the propellant chamber 3 ignites and explodes, thereby increasing the flying force of the smoke bomb. An insertion hole 19 through which the quick-fire wire 20 is inserted is provided in the portion.

Further, the red smoke chemical 18 is made of a mixture of potassium chlorate, rhodamine B cock, etc., and when ignited, it burns and generates red smoke, and is a lid plate that closes the open end of the bottomed cylindrical body 16. 21 and the colossus 17.

The fast-flaming wire 20 that ignites the red smoke powder 18 has a much faster ignition speed than a normal fuse so that when the propellant 13 is ignited and explodes, it is ignited almost at the same time and quickly ignites the red smoke powder 18k. The end of the bottomed cylindrical body 16 extending from the bottom 14 is inserted through a hole 22 provided in the partition plate 11 and introduced into the propellant chamber 3.

The opening edge of the bottomed cylindrical body 16 closed by the lid plate 21 is caulked inward to prevent the lid plate 21 from coming off.

The smoke chamber 5 located on the open end side of the ejection tube body of the smoke grenade 4 has a partition plate 23 mounted close to the smoke grenade 4 on the ejection tube body 2.
and a partition plate 24 mounted on the opening end side at a distance from the partition plate 23, and the smoke chamber 5 is formed between the side surface of the injection cylinder main body 2 at a portion near the opening end. The chamber 5 is connected to the outside through a quick-fire wire insertion hole 25 provided through the chamber 5, and the chamber 5 is filled with a black smoke powder 26 made of, for example, a mixture of black powder and anthranthene.

A quick-fire wire 27 is inserted into the quick-fire wire insertion hole 25 to quickly transmit the flame ignited from the igniter to the black smoke powder 26 in the smoke powder chamber 5 by a fuse described later.

The fuse 7 is connected to an ignition part 6 arranged on the outer surface of the injection cylinder main body 2.
The end on the side opposite to the ignition part is connected to the quick-fire line 27 introduced into the smoke chamber 5.

The fuse 8 is for igniting from the ignition part 6 to the propellant chamber 3, and is formed to be appropriately longer than the fuse 7, and its end opposite to the ignition part is inserted through the fuse hole 12 and introduced into the propellant chamber 3. has been done.

For example, the fuses 7 and 8 are coated at a position shifted by an appropriate distance from the middle of the fuse of an appropriate length to one end to expose the wick, and an ignition charge is applied to the exposed portion of the wick. 28 is formed so as to share one ignition part 6 to which the ignition charge 28 is fixed, and the injection cylinder main body 2
It is fastened on the outer surface of the tube body 2 with a vinyl tape 29 or the like along the axial direction of the tube body 2.

The difference in length between the fuse 7 and the fuse 8 is that when the black smoke powder 26 in the smoke chamber 5, which is ignited and combusted by the fuse 7, is completely combusted, the fire ignited by the fuse 8 reaches the propellant chamber. It is best to set it so that it reaches 3.

The smoke grenade ejection tube 1 as described above is installed with the open end of the ejection tube main body 2 facing upward, and is used by tilting it appropriately depending on the direction of the shooting target and the distance from the target.

When the ignition section 6 is ignited, the fuse 7 and 8 guide the ignition section 6 to the smoke chamber 5 and propellant chamber 3.
The fuse 7 that leads to the smoke chamber 5 is shorter than the fuse 8 that leads to the propellant chamber 3, so the fire reaches the smoke chamber 5 first, and then reaches the propellant chamber after a while. The fire reaches 3.

Therefore, when the ignition part 6 is ignited, the fire reaches the smoke chamber 5 first, and the black smoke powder 26 in the pot 5 burns, thereby expanding, and the smoke chamber 5 is formed by the pressure at that time. The partition plate 24 that closes the upper end of the injection tube body 2 and the lid plate 9 that closes the upper end of the injection tube body 2 are pressed and expelled to the outside from the opening of the injection tube body 2, and the injection tube body 2 is opened. Black smoke spews upwards from the opening.

When the almost black smoke is completely blown out from the smoke chamber 5, the flame is transmitted to the propellant 13 in the propellant chamber 3 and the propellant 13 burns, and the strong pressure generated at that time causes the smoke bomb 4 to be fired. At the same time, the rapid fire wire 20 is ignited by the propellant 13 and guides the flame to the part filled with the red smoke powder 18 in the smoke bomb 4, and as a result, the red smoke powder 18 is ignited and burned, and the combustion generates electricity. Red smoke is Koros 17's fast fire wire insertion hole 1
9 and the fast-firing wire insertion hole 15 in the bottom 14 of the bottomed cylindrical body 16.

Therefore, the smoke bomb 4 is fired after smoke is ejected from the ejection tube 1, and flies along a trajectory while ejecting red smoke from the rapid-fire line insertion holes 15 and 19.

In this way, the smoke grenade ejection tube of the present invention forms a smoke chamber filled with smoke powder on the open end side of the tube body at the smoke bomb fitting portion of the tube body, and first burns the smoke powder in the smoke bomb chamber. Since smoke is ejected from the opening of the ejection tube and then a smoke bomb is ejected, the smoke is emitted from the ejection tube and/or the smoke from the smoke bomb fired from the ejection tube. It can be visually recognized, and visibility is extremely high.

Therefore, when used as a mock gun for defense training, it is possible to predict the ejection, ejection location, and trajectory of the shell based on both the smoke ejected from the ejection tube and the trailing smoke from the smoke bomb.
In addition, even if it is difficult or impossible to visually recognize the smoke ejected from the ejection tube due to the terrain of the ejection location, for example, it is possible to predict the ejection of the shell by visually recognizing the smoke trailing from the smoke bomb. On the other hand, even when it is difficult or impossible to visually see the smoke trailing from a smoke bomb, it is possible to predict the ejection of a shell by visually observing the smoke emitted from the ejection tube, which significantly improves visibility and improves training. Able to grasp the situation accurately and reliably.

Furthermore, since the trajectory of the shell can be predicted by the smoke from the smoke grenade, it is possible to train in a more realistic atmosphere, thereby developing the actual combat abilities of the soldiers.

Furthermore, the smoke grenade ejection tube of the present invention allows smoke to be visually recognized by both or at least one of the smoke ejected from the ejection tube and the smoke trailed by the smoke bomb, so that a person in distress can call for help. If used for this purpose, the possibility of being discovered by rescuers is extremely high, and it can also be effectively used as a signal tube for rescue purposes.

In the smoke grenade ejection tube of the present invention, the smoke grenade is inserted into the ejection tube opening end side of the propellant chamber formed at the inner bottom of the ejection tube body, and the smoke cartridge is inserted into the ejection tube body opening end side of the smoke grenade. It has a very simple structure and can be manufactured at a relatively low cost.
