Description

The present invention relates to a spraying device, and more particularly to a spraying device capable of spraying a liquid.

Conventionally, a spraying device capable of spraying various liquids is already known. As such a spraying device, for example, a spraying device capable of spraying water is known. As a result, water can be easily sprayed on the desired area. Therefore, it can be used not only for heat stroke countermeasures in summer, but also for watering flowers and suppressing the generation of dust at construction sites.

As the prior art document information related to the invention of this application, for example, Patent Document 1 is known.

However, in the above-mentioned conventional technique, the spraying device is used by placing it on a floor such as the ground. Therefore, it was difficult to move the place where the spraying device was used.

The present invention aims to solve such a problem, and an object of the present invention is to provide a spraying device in which a place of use can be easily moved.

According to one feature of the present invention, the spraying device includes a trolley capable of traveling on the floor and a nozzle attached to the trolley and capable of spraying a liquid.

Therefore, the nozzle can easily spray the liquid on the desired area as in the prior art. In addition, a dolly (spraying device) placed on the floor can be run. Therefore, it is easy to move the place where the spraying device is used.

According to another feature of the present invention, the nozzle is attached to the trolley via a gantry.

Therefore, the degree of freedom in the mounting position of the nozzle can be increased as compared with the case where the nozzle is directly mounted on the trolley.

Further, according to another feature of the present invention, the gantry is provided in a long shape from a central gantry attached to the trolley along the horizontal direction and an end pedestal further extending horizontally from both ends of the central gantry. There is. A plurality of nozzles are provided along the longitudinal direction of the central pedestal and the end pedestal. The end pedestal is hinged so that it can be folded and overlapped with respect to the central pedestal in an axial direction with the vertical direction or the horizontal direction as the axial direction.

Therefore, the central pedestal and the end pedestal of the gantry can be deployed so as to be located on the same straight line along the horizontal direction. That is, the gantry can be switched to the deployed state. Further, from this unfolded state, one end pedestal can be bent 180 ° toward the other and overlapped with respect to the central pedestal of the pedestal via a hinge. Further, from this unfolded state, the other end pedestal can be bent 180 ° toward one side and overlapped with the central pedestal of the pedestal via a hinge. Therefore, the gantry can be switched to the stored state. Therefore, when using the spraying device, the gantry can be switched to the deployed state to spray water over a wide area. Further, when the spraying device is not used, the gantry can be switched to the stored state and folded compactly.

Further, according to another feature of the present invention, a cover having a substantially U-shaped vertical cross section is attached to the central pedestal and the end pedestal to cover each mounting surface to which the nozzle is mounted. The cover is formed with a spray port that exposes the tip of the nozzle.

Therefore, the tip of the nozzle can be exposed from the cover. Therefore, the appearance of the central gantry to which the nozzle is attached can be enhanced by the cover while preventing the nozzle from hindering the spraying of the liquid.

Further, according to another feature of the present invention, the gantry is equipped with a lighting device capable of illuminating an area for spraying a liquid.

Therefore, the lighting device can illuminate the liquid spray area. Therefore, the liquid spraying status can be visually confirmed even at night.

Also, according to another feature of the invention, the spraying of the liquid is done by a high pressure pump.

Therefore, the liquid can be sprayed vigorously from the nozzle.

It is a top view of the spraying apparatus of FIG. It is a vertical cross-sectional view of the IV-IV line of the spraying device of FIG. It is a schematic view which enlarged the plane of the spraying apparatus of FIG. FIG. 5 shows a stored state of the spraying device.

Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS. 1 to 6. In the following description, the directions of up, down, front, back, left, and right are the directions of up, down, front, back, left, and right shown in each figure. First, the spraying device 1 according to the embodiment will be described with reference to FIGS. 1 to 5. The spraying device 1 mainly includes a carriage 10, a gantry 20, and a nozzle 58. Hereinafter, the carriage 10, the gantry 20, and the nozzle 58 will be described individually.

First, the carriage 10 will be described. The bogie 10 includes a bogie main body 11 composed of a vertically long rectangular parallelepiped frame-shaped frame, and four casters 13 attached to four corners of the bottom 12 of the bogie main body 11. With these four casters 13, the dolly 10 (spraying device 1) stationary on the floor 70 can be run (can run). The carriage 10 is configured in this way. The drive source for this traveling may be manual operation by the operator pushing or pulling the carriage body 11, or may be a motor, an engine, or the like (none of which is shown).

Next, the gantry 20 will be described. The gantry 20 mainly includes a stand portion 30 and a spray portion 40. The stand portion 30 has a rectangular bottom plate 31, a vertical angle 32 assembled so as to project upward from the surface 31a of the bottom plate 31, and a pair of front and rear brackets 33 from the tip 32b of the vertical angle 32. It is provided with a lateral angle 34 assembled so as to project toward the front side (the front side of the paper surface in FIG. 1) through the gap.

The vertical angle 32 includes a switch (not shown) for turning on / off the high-pressure pump 53 and the three lighting devices 60, which will be described later. The stand portion 30 is configured in this way. The stand portion 30 configured in this way has a bottom plate 31 assembled to the bottom portion 12 of the carriage 10 so that its vertical angle 32 projects upward from the internal space 14 of the carriage 10.

On the other hand, the spraying portion 40 includes a long central pedestal 41, a pair of long left and right end pedestals 42, and a short intermediate pedestal 43. The left end 41a of the central gantry 41 and the base end 42a of the left end gantry 42 are assembled via a hinge 44 whose vertical direction (vertical direction) is the axial direction of the rotation shaft 44a (see FIG. 5). That is, the left end pedestal 42 is assembled via the hinge 44 so as to be bent around the axis with the vertical direction (vertical direction) as the axial direction with respect to the left end 41a of the central pedestal 41.

Further, the right end 41b of the central gantry 41 and the base end 43a of the intermediate gantry 43 are assembled via a hinge 44 whose vertical direction (vertical direction) is the axial direction of the rotation shaft 44a. That is, the intermediate pedestal 43 is assembled via the hinge 44 so as to be bent around the axis with the vertical direction (vertical direction) as the axial direction with respect to the right end 41b of the central pedestal 41 and overlapped. The left end 41a and the right end 41b of the central gantry 41 correspond to "both ends of the central gantry" described in the claims. Moreover, the fact that it is assembled in this way corresponds to "extending along the horizontal direction" described in the claims.

Further, the tip 43b of the intermediate pedestal 43 and the base end 42a of the right end pedestal 42 are assembled via a hinge 44 whose vertical direction (vertical direction) is the axial direction of the rotating shaft 44a. That is, the right end pedestal 42 is assembled via a hinge 44 so as to be able to be folded and overlapped with respect to the tip 43b of the intermediate pedestal 43 in an axial direction with the vertical direction (vertical direction) as the axial direction. Assembling via the hinge 44 in this way corresponds to the "hinge connection" described in the claims.

The central gantry 41 is formed so that the vertical cross section having the opening 41c is substantially U-shaped (see FIG. 4). A plurality of U-shaped bolts 45 are attached to the substantially U-shaped concave surface 41d of the central gantry 41 at appropriate intervals so as to have an internal space 45a. The concave surface 41d corresponds to the "mounting surface" described in the claims. A second hose 56 and a third hose 57, which will be described later, are passed through the internal space 45a. Further, a cover 46 having a substantially U-shaped vertical cross section is attached to the central gantry 41 so as to cover the opening 41c.

The cover 46 is formed with a spray port 46a that is compatible with the nozzle 58 described later (the tip 58a of the nozzle 58 can be exposed). As a result, the tip 58a of the nozzle 58 can be exposed from the cover 46. Further, the central gantry 41 is provided with a lighting device 60. The same applies to the end pedestal 42 and the intermediate pedestal 43 as described above. The spray unit 40 is configured in this way.

The central pedestal 41 of the spray portion 40 configured in this way is assembled to the tip 34b of the lateral angle 34 of the stand portion 30 along the left-right direction (horizontal direction). Therefore, the central pedestal 41 of the spraying portion 40, the pair of left and right end pedestals 42, and the intermediate pedestal 43 can be deployed so as to be located on the same straight line in the left-right direction (see FIG. 5). That is, the spray unit 40 can be switched to the deployed state.

From this unfolded state, the left end pedestal 42 can be bent 180 ° from the rear to the right and overlapped with the central pedestal 41 of the spraying portion 40 via the hinge 44. Further, from this unfolded state, the intermediate pedestal 43 can be bent 90 ° backward with respect to the central pedestal 41 of the spraying portion 40 via the hinge 44. Further, the right end pedestal 42 can be bent 90 ° to the left with respect to the bent intermediate pedestal 43 via the hinge 44 (see FIG. 6).

That is, the left end pedestal 42 can be bent 180 ° and overlapped with the central pedestal 41 of the spraying portion 40 via the intermediate pedestal 43. Therefore, the spray unit 40 can be switched to the stored state. Of course, if the reverse operation is performed, the spray unit 40 can be returned from the stored state to the deployed state.

Finally, the nozzle 58 will be described. Returning to FIGS. 1 to 3, a storage box 50 is assembled in the internal space 14 of the carriage body 11 of the carriage 10. The storage box 50 includes a cord reel 51, a hose reel 52, and a high-pressure pump 53. The cord reel 51 is connected to an external commercial power source (for example, AC100V). Power is supplied to the three lighting devices 60 and the high-pressure pump 53 described above via the cord reel 51.

Further, the inlet (not shown) of the hose reel 52 is connected to an external water pipe (not shown). Further, the inlet (not shown) of the high-pressure pump 53 is connected to the outlet (not shown) of the hose reel 52 via a hose (not shown). Further, the outlet (not shown) of the high pressure pump 53 is connected to the inlet 54a of the first hose 54. The outlet 54b of the first hose 54 is connected to the inlet (not shown) of the bifurcated branch member 55.

The first outlet (not shown) on the left side of the branch member 55 is connected to the inlet (not shown) of the second hose 56. The second hose 56 is arranged so as to pass the internal space 45a of the U-shaped bolt 45 toward the tip 42e of the left end frame 42. The second hose 56 is provided with six nozzles 58 at appropriate intervals along the longitudinal direction. Similarly, the second outlet (not shown) on the right side of the branch member 55 is connected to the inlet (not shown) of the third hose 57.

The third hose 57 is arranged so as to pass the internal space 45a of the U-shaped bolt 45 toward the tip 42e of the right end frame 42. The third hose 57 is provided with six nozzles 58 at appropriate intervals along the longitudinal direction. When provided in this way, the nozzle 58 is attached to the carriage 10 via the gantry 20. Each tip 58a of the total of 12 nozzles 58 is exposed from the spray port 46a of the cover 46 as described above. The nozzle 58 is configured in this way. The spraying device 1 is composed of the carriage 10, the gantry 20, and the nozzle 58.

Subsequently, the operation of the spraying device 1 will be described. First, an operator (not shown) operates a switch that turns on the high-pressure pump 53. Then, the high pressure pump 53 operates. Therefore, water from the water pipe is sprayed from each tip 58a of the high pressure pump 53, the first hose 54, the second hose 56, the third hose 57, and the 12 nozzles 58. Therefore, as in the prior art, water can be easily sprayed (sprayable) on a desired area. As a result, it can be used not only for heat stroke countermeasures in summer, but also for watering flowers and suppressing the generation of dust at construction sites.

When the spraying is finished, the operator operates a switch for turning off the high pressure pump 53. Then, the high pressure pump 53 stops. Therefore, this spraying ends. Further, when the switch for turning on the three lighting devices 60 is operated as needed, such as at night, the three lighting devices 60 operate. Therefore, the water spraying status can be visually confirmed even at night.

The spraying device 1 according to the embodiment of the present invention is configured as described above. According to this configuration, the spraying device 1 includes a carriage 10 and a nozzle 58. Since the nozzle 58 is provided, water can be easily sprayed on a desired area as in the prior art. Further, since the trolley 10 having the casters 13 is provided, the trolley 10 (spraying device 1) stationary on the floor 70 can be run. Therefore, it is easy to move the place where the spray device 1 is used.

Further, according to this configuration, the nozzle 58 is attached to the carriage 10 via the gantry 20. Therefore, the degree of freedom in the mounting position of the nozzle 58 can be increased as compared with the case where the nozzle 58 is directly mounted on the carriage 10. That is, the nozzle 58 can be attached to the carriage 10 at a free position via the gantry 20.

Further, according to this configuration, the spraying device 1 is provided with a total of 12 nozzles 58. Further, the spraying portion 40 of the gantry 20 of the spraying device 1 includes a long central pedestal 41, a pair of long left and right end pedestals 42, and a short intermediate pedestal 43. The left end 41a of the central gantry 41 and the base end 42a of the left end gantry 42 are assembled via a hinge 44 whose vertical direction (vertical direction) is the axial direction of the rotation shaft 44a. Further, the right end 41b of the central gantry 41 and the base end 43a of the intermediate gantry 43 are assembled via a hinge 44 whose vertical direction (vertical direction) is the axial direction of the rotation shaft 44a. Further, the tip 43b of the intermediate pedestal 43 and the base end 42a of the right end pedestal 42 are assembled via a hinge 44 whose vertical direction (vertical direction) is the axial direction of the rotating shaft 44a.

Therefore, the central pedestal 41 of the spraying portion 40, the pair of left and right end pedestals 42, and the intermediate pedestal 43 can be deployed so as to be located on the same straight line in the left-right direction. That is, the spray unit 40 can be switched to the deployed state. Further, from this unfolded state, the left end pedestal 42 can be bent 180 ° from the rear to the right and overlapped with the central pedestal 41 of the spraying portion 40 via the hinge 44. Further, from this unfolded state, the intermediate pedestal 43 can be bent 90 ° backward with respect to the central pedestal 41 of the spraying portion 40 via the hinge 44. Further, the right end pedestal 42 can be bent 90 ° to the left with respect to the bent intermediate pedestal 43 via the hinge 44. That is, the left end pedestal 42 can be bent 180 ° and overlapped with the central pedestal 41 of the spraying portion 40 via the intermediate pedestal 43. Therefore, the spray unit 40 can be switched to the stored state. As a result, when the spraying device 1 is used, the spraying unit 40 can be switched to the expanded state to spray water over a wide range. Further, when the spraying device 1 is not used, the spraying unit 40 can be switched to the stored state and folded compactly.

Further, according to this configuration, a cover 46 is attached to the central gantry 41 so as to cover the opening 41c. The cover 46 is formed with a spray port 46a that is compatible with the nozzle 58 (the tip 58a of the nozzle 58 can be exposed). Therefore, the tip 58a of the nozzle 58 can be exposed from the cover 46. Therefore, the appearance of the central gantry 41 to which the nozzle 58 is attached can be enhanced by the cover 46 while preventing the nozzle 58 from hindering the spraying of water.

Further, according to this configuration, the lighting device 60 is provided on the central pedestal 41 and the pair of left and right end pedestals 42. Therefore, the lighting device 60 can illuminate the water spray area. Therefore, the spraying state of water can be visually confirmed even at night.

Further, according to this configuration, the spraying of water is performed by the high pressure pump 53. Therefore, water can be sprayed vigorously from the nozzle 58.

The content described in the embodiment is not limited to this, and is a design that can be appropriately determined as long as the gist of the invention does not change. In the embodiment, an example in which the "liquid" is "water" has been described. However, the present invention is not limited to this, and the "liquid" may be "various solutions (for example, chemicals)". Further, the casters 13 provided on the carriage body 11 may be tires, rollers, wheels, or the like. Further, the hinge 44 may be assembled so that the axial direction of the rotating shaft 44a is the front-rear direction. Further, the number of nozzles 58 may be singular. Of course, the number of nozzles 58 is not limited to 12 as long as a plurality of nozzles 58 are provided, and any number of nozzles 58 may be provided.
