1 to 4 and 11, the spray apparatus for an air spray for an elastic coat according to the first embodiment of the present invention includes a body 100, a paint supply unit 200, an air supply unit 300, 400).

The body 100 serves to spray and guide the paint 2, the air, and the granular material 6. At this time, the body 100 can be applied in various shapes and various materials.

Of course, although not shown, the body 100 may have a handle.

The paint supply unit 200 supplies the paint 2 to the inside of the body 100. Although not shown, the paint supply unit 200 includes a paint tank. In addition, the paint (2) is applicable in various ways, and is not limited to colors.

Particularly, the body 100 forms the paint transfer passage 112 on the inner side. The paint supply unit 200 supplies the paint 2 to the paint transfer path 112. As the paint 2 supplied to the paint transfer path 112 must be ejected from the body 100, the paint 2 is formed to be open to both sides of the paint transfer path 112.

In addition, a plurality of paint transfer paths 112 may be provided in the body 100, and four of the paint transfer paths 112 are formed for convenience. Further, in the case of a plurality of the paint transfer paths 112, the central axes may be arranged parallel to each other or may be arranged to be inclined with respect to each other.

The paint supply unit 200 may supply the paint 2 to the plurality of paint transfer paths 112 at the same time or may sequentially supply the paint 2 with a time difference.

The paint supply unit 200 may be provided in a one-to-one correspondence with the plurality of paint transfer paths 112 or may be provided to supply the paint 2 to at least two paint transfer paths 112.

In particular, the diameter of the paint transfer passage 112 is not limited. The paints 2 conveyed to the respective paint conveyance passages 112 may be the same color or different colors, and some of the paints 2 may have the same color.

On the other hand, when the paint supply unit 200 is connected to the paint transfer path 112 in a one-to-one manner, the hose connecting the paint supply unit 200 and the paint transfer path 112 becomes complicated.

Thus, the body 100 forms one or more paint transfer passages 112 for guiding the transfer of the paint 2 to the inside. That is, two or more paint transfer passages 112 are connected to the paint supply hose 116 from the outside of the body 100. For convenience, the paint supply hose 116 is assumed to connect two paint transfer paths 112. Of course, a port may be provided on the inflow side of the paint transfer passage 112 so as to connect the paint supply hose 116.

In addition, the paint supply unit 200 can directly supply the paint 2 to the paint supply hose 116. Of course, the painting material supplying section 200 may supply the painting material 2 with another time to the other painting material supply hose 116 at the same time, and may also supply the painting material 2 at the same time.

In addition, the air supply unit 300 serves to supply air to the body 100. The air serves to provide a powder output to the paint 2 so that the paint 2 supplied into the body 100 is sprayed at a high pressure. The air supply unit 300 includes a compressor and the like.

At this time, the body 100 forms an air feed path 122 to allow air to be fed from the air feeder 300. The air conveyance passage 122 is formed to be open to both sides of the body 100.

More specifically, one or more air conveying passages 122 may be formed in the body 100, and one air conveying passage 122 is formed in the body 100 for convenience.

The body 100 is formed so that the supplied air and the paint 2 are mixed. This is to allow the paint 2 to be sprayed at a high pressure by air sprayed at a high pressure. Of course, the diameter of the air conveyance passage 122 is not limited.

Therefore, the body 100 guides the separately supplied air and the paint 2 mixed therein and then injected.

On the other hand, the granule supply part 400 serves to supply the granular material 6 to increase the cohesive force of the paint 2 to be sprayed. Particularly, the granular material 6 may be sand, gravel, or the like. Further, the kernel member 6 may be provided with a function such as having a humidity control function.

Particularly, when the particle member 6 has the functionality, the particle member 6 is mixed with the paint 2 at the discharge side of the paint 2 of the body 100. [

In other words, the pellet member 6 is conveyed together with the air through the air transfer passage 122 inside the body 100, and mixed with the paint 2 inside the front side of the body 100. That is, the granule supplying part 400 and the air supplying part 300 inject air and the granular material 6 from the outside of the body 100 into the body 100 after mixing them.

Particularly, the granular material 6 is supplied from the granular supplying part 400 to the air supplying part 300, and then is injected into the body 100 together with the air to partially fill the surface of the paint 2 to be discharged.

Of course, the granular material 6 and the air may be mixed in advance within the body 100 before mixing with the paint 2.

As a result, the entire surface of the granular material 6 can be prevented from being coated with the paint 2, so that a function such as dehumidification can be exerted.

In addition, the body 100 may have a cap 140 for imparting straightness to the paint 2 to be discharged. The cap 140 forms an inclined surface 142 inside or in contact with the front side of the body 100. The discharged air and the granular material 6 and the paint 2 are moved along the inclined surface 142 and discharged to the discharge hole 144 formed in the cap 140. [ The cap 140 may be detachably coupled to the front side of the body 100 in various manners.

In addition, the body 100 may form a mixing space 130 for mixing the paint 2 and the air including the granular material 6 on the discharge side of the paint 2. At this time, as the mixing space 130 is clogged by the cap 140, the finally mixed paint 2, the granular material 6, and the air are discharged to the discharge hole 144.

Of course, the nature, thickness, and number of the kernel member 6 are not limited.

On the other hand, the granule supply unit 400 can supply the granular material 6 of a fixed amount or a predetermined amount to the air supply unit 300 by automatic equipment.

11, the granule supply unit 400 includes a hopper 410, an opening and closing member 420, and an operation unit 430. As shown in FIG.

The hopper 410 is opened at one side to allow the ejection of the granular material 6. Particularly, the hopper 410 can be opened upward to feed the granular material 6, and can be opened downward to discharge the granular material 6.

Of course, the hopper 410 can be applied in various shapes and various materials.

The opening and closing member 420 serves to open and close one side of the hopper 410, that is, the lower side thereof, to open and close the granular member 6 by a preset amount. Here, the opening and closing member 420 is applicable to various materials such as a thin membrane or a thin plate.

The operating part 430 serves to operate the opening and closing member 420 so as to repeatedly open and close the lower side of the hopper 410.

Here, the actuating part 430 includes a rib 432 and a swinging pin 434.

The ribs 432 are provided inside the air hose 310 included in the air supply part 300. At this time, the ribs 432 are formed so that a predetermined amount of air can flow. Of course, the ribs 432 can be deformed into various shapes and fixedly mounted inside the air hose 310 in various ways.

Particularly, the air hose 310 is formed so as to allow the granular material 6 falling down to the lower side of the hopper 410 to flow in. In addition, the air hose 310 may be deformed into various shapes.

One side of the swing pin 434 is connected to the rib 432, and the other side is connected to the opening and closing member 420. The rib 432 is pivotably connected to one side of the swing pin 434.

Therefore, when the air flows into the air hose 310 at a high pressure, the swing pin 434 is repeatedly shaken while being fixed in position. As a result, the swing pin 434 shakes the opening and closing member 420. Therefore, the opening and closing member 420 repeatedly opens and closes the lower side of the hopper 410, and guides the granular material 6 to the air hose 310.

At this time, a part of the opening and closing member 420 is fixedly connected to the lower side of the hopper 410, and the remaining part is simply in contact with the lower side of the hopper 410.

Particularly, the air hose 310 can be inclined so that the falling granular material 6 stably flows into the air conveying passage 122 of the body 100.

The granule supply unit 400 includes a granule transfer passage 450, a granule transfer pipe 460, and a granulating unit 470.

The granule transfer passage 450 is connected to the discharging side of the paint 2 from the peripheral surface of the body 100 and serves as a passage for supplying the granular material 6 to the paint 2 to be discharged. That is, the kernel transfer passage 450 is formed to be connected from the peripheral surface of the body 100 to the mixing space 130.

Of course, the number and diameter of the kernel transfer passages 450 are not limited.

In addition, the grain passageway (460) is connected to the grain conveyance passage (450) from the outside of the body (100). At this time, the grain conveyance passage 460 is connected to the entrance side of the granule conveyance passage 450 by various methods. In addition, for spraying, as the user must carry the body 100, the granulating vessel 460 can be made of a flexible material.

The granulating unit 470 serves to forcibly feed the granular material 6 to the granulating tank 460.

As an example, the grain feeding unit 470 includes a grain feeding tube 472, a screw 474, and a drive motor 476.

The pellet feeding pipe 472 is connected to the pellet feed pipe 460. At this time, the grain feeding pipe 472 is made rigid.

The screw 474 is rotatably inserted into the grain feeding pipe 472. Thus, the screw 474 rotates and serves to forcibly feed the granular material 6 fed to the grain feeding pipe 472.

The drive motor 476 serves to forcibly rotate the screw 474. In particular, the grain feeding tube 472 is made rigid as the screw 474 is rotatably mounted therein.

7 and 8, an apparatus for spraying an air spray for an elastic coat according to a fourth embodiment of the present invention includes a body 100, a paint supply unit 200, an air supply unit 300, and a granule supply unit 400 .
