Description

Eco-friendly practice grenade and its manufacturing method {HAND GRENADE FOR NATURE FRIENDLY PRACTICE AND THE MANUFACTURE METHOD}

The present invention relates to an environmentally friendly practice grenade and a method for manufacturing the same, and more particularly, so that it can be extinguished in a natural state without the need to recover after use a practice grenade consisting of a body made of a mineral material and a fuse made of biodegradable starch. It is.

Grenade is a small bomb for melee combat that kills or destroys an enemy or weapon in close combat with an enemy, and is made relatively light so that a person can pick it up by hand. It consists of a fuse to ignite the explosives charged in the body, and the fuse consists of a safety loop, a safety creep, and a safety handle.

The types of grenades are classified into subdivision grenades for personnel killing, attack grenades for weapon destruction, gas grenades for lowering enemy power, smoke grenades for signaling, and such grenades. It is necessary to learn enough usage and safety rules in advance as it can damage itself and allies by carelessness of the user.

Therefore, when training is not a real combat situation, the training grenade is trained with a relatively small explosive grenade, and the grenade is made of a metallic material with a body and fuse, and the grenade is collected and reused after use.

However, if the practice grenade is not recovered after use, the body and fuse are leaked out to be converted into a similar explosive, and if not recovered, a problem of destroying the natural environment occurs.

In addition, the terrain of the training site is diverse, and other objects or weeds require considerable time and manpower to recover the grenade body and fuse after training, and the training bottle is always burdened with the need to recover the training grenade, thereby reducing the training effect. There is always a risk of losing the used hand grenade.

The present invention has been made to improve the above problems in the prior art, by making the body and fuse of the practice grenades made of mineral material and biodegradable starch so as to disappear naturally without the need for recovery after use of the practice grenades.

14: fuse coupling portion 16: mineral material

20: fuse 22: fuse coupling portion

24: safety ring 26: safety creep

The object is that the inner body is made of a mineral material and the fuse coupling portion is formed on the upper portion, the fuse coupled to the fuse coupling portion of the body is provided with a safety ring and a safety creep to the upper side and a safety handle is formed on one side In the practice hand grenade that is coupled to the fuse coupling screw and the detonator tube formed in the lower side,

The body is made of natural minerals made of silica, loess, straw, natural hemp fiber, which can be naturally decomposed after throwing, and the fuse can be made of biodegradable starch.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in FIGS. 1 and 2, the grenade for practice is made of a mineral component in which the body 12 is mixed with silica sand, loess, straw, and natural hemp fibers in a predetermined ratio, and the fuse is upper side of the body 12. Fuse fastening portion 14 for assembling 20 is formed, the fuse 20 is fastened to the body 12 is made of biodegradable starch (corn starch, potato starch, PP), the fuse ( A detonation pipe 30 is formed on the lower side of the 20, a fuse coupling screw 22 is formed on the upper side of the detonating pipe 30, the safety ring 24, the safety to the upper portion of the fuse coupling screw 22 Creep 26 is formed, the safety handle 28 is formed to one side.

In addition, the body 12 is filled with the mineral material 16, the fuse 20 is preferably starch and PP (Poly Propylene) is mixed in a ratio of 3: 7.

It looks at the manufacturing method and operation state for the eco-friendly practice grenade which is the present inventors constituting such a configuration.

The components constituting the body 12 of the training grenade 10 are mineral materials, mainly composed of silica sand and loess, and the fuse 20 has biodegradable starch (corn, potato, P.P) as a main component.

Looking at the manufacturing method of the body 12 of the practice grenade 10 with reference to Figure 3 as follows, the raw material supply step (ST2) is made to supply the silica sand and loess to the stirrer, the raw material supplied is a uniform ratio The stirring step (ST2) for stirring in a stirrer is made, the primary processing step for producing in the shape of the body 12 by combining with natural hemp fibers and straw to the raw material stirred by the stirring step (ST2) ( ST3) is made, a heat treatment step (ST4) is performed to give a rigidity to the body 12 formed by the primary processing step (ST3), the rigidity is given by the heat treatment step (ST4) In order to assemble the fuse 20 to the body 12, a secondary processing step (ST5) is formed to form a fuse coupling portion 14, and separate from the body 12 made from the secondary processing step (ST5) Made of biodegradable starch material Fuse assembly step (ST6) is made to assemble the fuse 20, the manufacturing process of the hand grenade (10) is made through the packaging step (ST7) is to be delivered to use.

Here, the heat treatment step (ST4) is to give the rigidity to the body 12 in order to increase the explosion strength and prevent damage during assembly and normal distribution and storage.

The practice grenade produced by such a manufacturing method is easy to obtain the material because the body 12 is made of silica sand and loess, and has the same weight and shape as the practice grenade or actual grenade made of a conventional metal material. By being produced, you can train like a real one.

In addition, since the material of the practice grenade 10 is composed of a body 12 of a biodegradable mineral body and a fuse 20 of biodegradable starch material, it can be used without the need to recover the practice grenade after use.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the eco-friendly practice hand grenade of the present invention may be variously modified and implemented by those skilled in the art.

As an example, in the embodiment of the present invention has been described to produce a body made of a mineral that is a mixture of silica sand and ocher and to produce a fuse made of biodegradable starch, but this is applied to be made of other natural decomposition and nature-friendly materials It is possible.

Therefore, these modified embodiments should not be understood individually from the technical spirit or prospect of the present invention, the modified embodiments should fall within the appended claims of the present invention.

As described above, according to the present invention, since the body and the fuse are made of naturally decomposed ocher and biodegradable starch, training grenades do not need to be recovered after use, so that a large number of people can be trained in a short time. It can be maximized and used with environmentally friendly materials so that it can be used without concern for environmental pollution. Also, since the material is a mineral material, it has an excellent effect of explosion and explosion at the time of explosion and minimizes the user's injury due to the use of bullets. There is an effect that can be done.

In addition, the manufacturing cost of the grenade for practice can be significantly lowered, so that the use cost is low, and there is no need for recovery, thereby creating a variety of training environments, as well as causing a higher training effect to the trainer or the training operator. .
