Description

Spray device and spray method Technical field

The present invention relates to a spraying apparatus and a spraying method suitable for spraying a large amount of spray on, for example, a greenhouse, a greenhouse, a livestock barn, and agricultural products. Background art

FIG. 14 is a side view showing an outline of a conventional spray device. A spray nozzle n is disposed in front of a blower fan f that is driven to rotate by a motor m, and the spray nozzle n is connected to a high water pressure generating section by piping.

In this apparatus, fine mist is generated by jetting out pressurized water from the spray nozzle n, and the mist is sent in one direction by wind force generated by the rotation of the blower fan f.

When this device is used in a greenhouse in summer, the inside of the house can be cooled by the latent heat of vaporization of fine water droplets, and the temperature inside the house can be suppressed. Also, when used in livestock barns, it can provide a cooling function. It is also used for spraying chemicals such as pesticides.

However, due to the low ability of the spray nozzle n to generate fine fog, a large number of spray nozzles n must be installed to cool a large area or spray agrochemicals, which increases equipment costs. Become.

In addition, in order to generate fine fog from the spray nozzle n, it is necessary to send pressurized high-pressure water, but the equipment and power consumption for that are also factors that put pressure on farmers' management.

The technical problem of the present invention is to focus on such a problem and to use a simple device. To generate a large amount of fine fog and make it possible to spray over a wide area, which can contribute to streamlining of farmers' management in aspects such as temperature control and chemical spraying.

Disclosure of the invention

The technical problem of the present invention is solved by the following means.

1. The portion of the cylinder attached to the rotary drive shaft opposite to the portion attached to the drive shaft has a structure of a spray device in which an opening is provided so that a water supply pipe can be inserted. A large number of through-holes are formed in the peripheral wall of the cylindrical body to communicate between the inside and the outside. Further, a net is disposed outside the peripheral wall of the cylindrical body so as to surround the outer periphery of the cylindrical body. The cylindrical body may be cylindrical or polygonal, and the dimensional ratio between the diameter D and the length L is arbitrary.

Thus, from the opening 2c of the cylinder 2 attached to the rotary drive shaft 1,

However, since the end of the water supply pipe 3 can be inserted, a large amount of water can be continuously supplied into the cylindrical body 2. Then, water is scattered by centrifugal force from a large number of through holes 2a in the peripheral wall of the cylindrical body 2, and a large amount of fine fog can be generated by the nets 4, 7, 8, 11 and the like on the outer side.

Also, since water can be supplied using ordinary water supply, there is no need for a special pressure generator like a spray nozzle.

2.A plurality of the above nets are arranged almost concentrically, and the inner net has a coarse mesh and the outer net has a fine mesh.

As described above, a plurality of nets are arranged substantially concentrically on the outer side of the cylindrical body 2, and the mesh on the inner side is made coarser, and the mesh on the outer side is made finer. Fine fog can be generated reliably 3. A blower fan is disposed before or after the tubular body, and the rotary drive shaft of the tubular body is configured to be rotationally driven by a drive source of the blower fan or another independent drive source. There is a fogging device.

As described in (1) and (2) above, only the device that generates fine fog can be sprayed near by centrifugal force.However, as described in (3) above, by using a blower fan together, it can be farther and specified. Can be sprayed in the area.

In addition, by using a structure in which the shaft for rotating the cylinder 2 of the spray device and the shaft of the blower fan F rotate integrally, the driving force of the blower fan F can be used for driving the spray device as well. Since no driving source is required, it can be realized at low cost.

Of course, by rotating the cylinder with a drive source different from that of the blower fan F, the number of rotations of the atomizing cylinder 2 and the blower fan F can be set freely. The drive source in the present invention includes not only an electric motor, but also all actuators that generate rotational force, such as a hydraulic or pneumatic or hydraulic drive motor or an engine.

4. A large number of fins are radially fixed to the outside of the peripheral wall of the cylindrical body described in 1, 2, or 3, and a cylindrical net is arranged outside the peripheral wall of the cylindrical body. Outside the cylindrical net, a net having a finer mesh than the net is disposed with the sending side open in a tapered or arcuate shape. The arc-shaped net has a fixed structure or a structure that rotates with the cylinder.

As described above, by providing the rotating fins 10 on the outer periphery of the cylindrical body 2 to increase the chance of water droplets to rebound, fine fog can be generated smoothly and reliably. In addition, it collides with the tape-shaped or arc-shaped net 13 having a fine mesh, and is further atomized and guided to a target place.

5. Extends from the center to the outer periphery between opposing disks arranged opposite to each other / 7 8

The impeller has a structure in which a plurality of impellers are sandwiched and arranged, and an opening for water supply is formed in the center of the impeller. The blades may be formed integrally with one disk and fixed to the other disk with screws or adhesive.

In this way, when a plurality of blades extending from the center to the outer periphery are provided in the space between the opposed disks and water is supplied to the center, fine mist can be efficiently generated by centrifugal force due to the rotation of the plurality of blades. However, since the centrifugal force is large, the centrifugal force makes it possible to spray a wider and farther area.

6. A spray device provided with a blowing means, wherein the shaft of the impeller described in 5 is connected to the same driving source as the blowing means or another driving source.

As described above, when the shaft of the impeller described in 5 is connected to the same driving source as the blowing means or another driving source, and the structure using the blowing means is used, a farther and more wide area by the blowing air is provided. Can be sprayed.

7. A spraying device in which the opposed disk described in 5 or 6 is formed in a bowl shape. In this way, if the opposing disk is bowl-shaped, it is guided in the direction of the opening of the bowl-shaped body and sprayed, so it can be sprayed toward the target location even without a blower, and the blower is also used Then you can spray farther.

8. A spray device in which a plurality of obstructing members are arranged in a space between the opposed disks described in 5, 6, or 7 so that water flowing from the water supply port collides with the space. .

In this way, since a plurality of obstructing members are arranged in the space between the opposed disks so as to flow from the water supply port and collide with water, the water supplied to the central portion of the opposed disk is When the particles are scattered by centrifugal force, they repeatedly collide with the obstacles and scatter, resulting in fine particles inside the impeller.

And because it is further scattered by the centrifugal force of the impeller, It becomes a mist. In addition, the fluid bounced back by the obstruction member scatters in various directions from the outer periphery of the impeller, so that when the fluid is discharged from the impeller, it becomes a finer mist.

9. The rotation axis of the atomization device that scatters the water supplied to the center of rotation outward by centrifugal force is arranged vertically, and at least below the atomization device, almost horizontally and radiates. This is a fogging device provided with a blowing means for generating wind in the direction.

In this way, by setting the rotation axis of the spray device in the vertical direction, it is possible to spray horizontally and at 360 degrees, and furthermore, it is possible to spray farther by the wind in the radial direction. It can be sprayed over a larger area with a single device by installing or moving it to a different location.

10. An invention of a spraying method, in which water supplied to the center of rotation is scattered by centrifugal force to be atomized, and then the scattered fine mist is sprayed in a desired direction by a blowing means. In this way, after fine mist is efficiently generated by centrifugal force, it can be sprayed farther by spraying with air blowing means, spraying over a wide area to control the temperature, It can be sprayed, washed off salt attached to agricultural products, and sprayed with water, and the use of the spray device is expanded.

Next, an embodiment will be described as to how the spray device and the spray method according to the present invention are actually embodied.

[Rotary tube structure spraying device]

In each figure, F is a fan for blowing air, which is driven to rotate by a motor and generates wind for blowing fine mist generated by a fine mist generator 9 having a rotary cylinder structure to a target area.

FIG. 1 shows a first embodiment of a rotary tubular spray device according to the present invention, in which a tubular body 2 is attached to the front end of a shaft 1 of a blower fan F. This cylinder

L For example, an empty can such as canned juice can be used for the item 2, and the bottom 2 b is fixed to the tip of the shaft 1.

A large number of through holes 2a communicating with the inside and outside are formed in the peripheral wall of the cylindrical body 2, and the tip 3a of the water supply pipe 3 is inserted through an opening 2 opposite to the bottom 2b.

Reference numeral 4 denotes a cylindrical net, which is formed by winding a fine mesh with a cylindrical shape. The number of turns is arbitrary, and if the number of turns is two or three times, the mesh is overlapped, so that the same effect as a finer mesh can be obtained.

The tubular net 4 is preferably provided at a distance from the outer peripheral wall of the tubular body 2 as shown in the figure, but may be wound directly over the outer peripheral wall of the tubular body 2. The cylindrical guard 5 arranged so as to surround the blower fan F is connected to and supported by the main body of the motor M via several support arms 6. In order to attach the atomization device to the installation location, the guard 5 may be used to attach the atomization device with bolts or nuts, or the motor M body may be attached with bolts or nuts.

In this fine mist generator 9, when the main cock of the water supply pipe 3 is opened, water is supplied into the cylinder 2 from the water supply pipe end 3a. As shown in the figure, when the water supply pipe tip 3a has a fully open structure, it is preferable that the water flowing out from the water supply pipe tip 3a draws an arc and drops to the inner wall of the cylindrical body 2 so as to have a force of zero.

In this state, when the blower fan F is rotated by the motor M, the wind in the direction of the arrow a is generated, and at the same time, the cylinder 2 and the net 4 rotate, so that the water supplied into the cylinder 2 is centrifugally generated. As a result, when the water flows out and scatters from the through-hole 2 a of the cylindrical body 2 to the outside, and then scatters outside due to centrifugal force on the net body 4, it forms a fine mist.

As a result, a large amount of water supplied by the water supply pipe 3 is continuously atomized. The wind generated by the blower fan F is transferred in the direction of arrow a, and a large amount of fine fog is continuously supplied to the target area.

Covering the fan 17 with a net 17 in front of the fine mist generator 9 prevents the fine mist generated from the fine mist generator 9 from scattering and disappearing outside the guard 5, All generated fine fog can be guided to the target location) o

The amount of fine mist generated by this device is incomparable with the amount generated by the conventional spray nozzle n as shown in Fig. 14, and the water flowing down from the water supply pipe 3 draws an arc as described above. Since it only needs to fall down, ordinary water supply can be used, and no special pressure generator or its drive motor is required as in the past.

As a blower fan, a large fan with a diameter of about 50 cm is used, the fine mist generator of the present invention is connected, and only a few units are installed in a house of about 200 tsubo, and the temperature drop of about 7 degrees It was realized and a sufficient cooling effect was obtained.

FIG. 2 shows a second embodiment of the rotary-tube-type atomizing device according to the present invention, and the structure of the fine mist generator 9 is different from that of the embodiment shown in FIG. In other words, a plurality of nets 7 and 8 are arranged outside the cylindrical body 2 having a large number of through holes 2a in the peripheral wall.

The two nets 7, 8 are formed in a cylindrical shape, but the inner net 7 has a coarse mesh, and the outer net 8 has a fine mesh. One end of each of the nets 7 and 8 is integrally connected to the bottom 2 b of the tubular body 2, and is attached to the drive shaft 1.

In this structure, when the blower fan F rotates, the driving body 1 rotates the cylinder 2 and the mesh bodies 7 and 8 together. Then, the scattered water that has flowed out from the through-hole 2 a in the peripheral wall of the cylindrical body 2 by centrifugal force collides with the coarse mesh 7, It scatters outside, then collides with the fine mesh 8 on the outside, and scatters outside through the mesh.

By making the mesh of the outer mesh 8 finer than the inner mesh 7 in this way, the generation of fine fog is more assured. In the illustrated example, two are provided like the nets 7 and 8, but three or more may be provided concentrically.

Further, the inner net 7 can be formed by winding a flat net into a cylindrical shape and reducing the number of turns at that time, and the outer net 8 can be selected and set by increasing the number of turns.

In Fig. 2, the fine fog generator is connected between the motor M and the blower fan F.

Since 9 is arranged, the generated fine fog is sucked by the wind force of the blower fan F, passes through the blower fan F, and is blown forward. In this case, if a net corresponding to the net 17 in FIG. 1 is attached to the support arm 6, the fine mist generated from the fine mist generator 9 is repelled by the net 17 in the direction of the blower fan F. However, it can be prevented from scattering to the outside. The fine mist generator 9 may be arranged in front of the blower fan F as in the case of FIG.

FIG. 3 shows a third embodiment of a rotary-tube-type spray device, and has a structure in which a motor M in FIG. This structure also corresponds to the structure in FIG. 1 in which the blower fan F is rotated in the reverse direction to blow air in the direction opposite to the arrow a.

As shown in FIG. 3, a structure in which the drive motor M is arranged in front of the blower fan F and the fine mist generator 9 of the present invention is arranged behind the blower fan F is also possible. However, since the motor M is always wet by the fine fog, there is a risk of deterioration of the motor M and leakage. Note that the fine fog generator 9 in this figure has the same structure as in the case of FIG.

1 In FIG. 1 and FIG. 2, the fine fog generator 9 has only one end supported on the shaft 1, so if the balance is poor, the rotation becomes unstable and the head may swing. On the other hand, in the embodiment shown in FIG. 3, the front end 3a of the water supply pipe 3 is fixed to the cylindrical guard 5 via several support arms 6a and stabilized, and the front end 3a The left end of the fine mist generator 9 is supported on the outer periphery of the device via a bearing 18. In the embodiment shown in FIG. 1, the right end of the fine mist generator 9 can be supported by the water pipe end 3a with the same structure.

The fine mist generator 9 is easily swung when the length L is large relative to the diameter D, and is difficult to occur when the length L is small, so the fine mist can be generated by shortening the length L as much as possible. The swing of the container 9 can be suppressed.

FIG. 4 is another embodiment of the fine fog generator 9, wherein (1) is a cross-sectional view at the center, and (2) is a cross-sectional view taken along the line AA in (1). The shaft 1 of the motor M passes through the center of the cylinder 2, and the bottom of the cylinder 2 is fixed to the shaft 1. A blower fan F is attached to the end of the shaft 1 of the motor.

A large number of through holes 2 a are formed in the peripheral wall of the cylindrical body 2, and a large number of fins 10 are fixed radially outside the cylindrical body 2. The fins 10 are arranged at an interval S in a direction parallel to the motor shaft 1.

A cylindrical mesh 11 is disposed outside the peripheral wall of the cylindrical body 2, and a fin facing inward in the interval S between the radial fins 10 is provided on the inner periphery of the cylindrical mesh 11. 1 and 2 are fixed. Further, a tapered net 13 with a finer mesh than the net 11 is disposed outside the net 11 with a fin ^).

The tapered net 13 is arranged in the direction in which the fine fog delivery side shown by the arrow a opens, and the small diameter portion and the end of the net 11 with the fin are fixed to the support frame 14, and the motor M It is attached to and supported by the main body. Therefore

/ 0 In this figure, the double nets 11 and 13 have a fixed structure ο

In this structure, when the cylinder 2 rotates while supplying water into the cylinder 2, the water flowing out of the through hole 2 a by centrifugal force collides with the finned net 11 and the fin 12. Although it bounces off, it is bounced outward by the rotating fins 10 and scatters outside through the mesh of the finned net 11 to efficiently and reliably spray fog. Be transformed into

Then, the air is sucked in the direction of the blower fan F by the wind in the direction of the arrow a due to the rotation of the blower fan F, passes through the blower fan F, and is sprayed forward. If fine fog generated from the net 11 with fins is not sucked in the direction of the blower fan F, it hits the slope of the tapered net 13 outside the blower fan F and Bounces off and is sucked in the fan F direction ο

In addition, a part of the mist passes through the mesh of the tape-like net 13 and becomes finer mist. As a result, the mist becomes lighter and finer, and the arrow a Sucked in the direction. It should be noted that the net 13 can be formed in an arc shape like the net 17 in FIG. 3 instead of the taper shape.

For the fins 10 and 12, it is better to fix the slender plate diagonally to increase the chances of collision of water droplets, and to use the fins 10 and 12 as a plate with a concave or convex surface. Using the body is more effective.

In the illustrated structure, the finned net 11 and the tapered net 13 are fixed to the motor main body, but the support frame 14 is separated from the motor M main body side and connected to the motor shaft 1 side. Thus, a structure that can rotate integrally with the cylinder 2 can be provided. In this way, when rotating, it may be arranged in front of the blower fan F as shown in FIG. In addition, the inward fins of

It is also possible to omit 12 and use only a cylindrical net.

/ f In FIGS. 1 to 4, the water supply pipe tip 3a inserted into the cylinder 2 does not fully open the tip, but closes the opening at the tip as shown in FIG. If the water is sprayed so as to be dispersed in the cylindrical body 2 by inserting and forming a large number of through holes 3 b in the side wall, atomization can be performed more effectively. FIG. 5 shows an embodiment of the cylindrical body 2, in which a nail is driven into the peripheral wall of an empty can, such as a canned juice, from the direction of the arrow to form a through hole 2a. When the nail is driven, by penetrating to the opposite peripheral wall, the burrs around the through-hole 2a 15 and 16 forces <<, the burr 15 of the first through-hole opened inwards, 2 The burr 16 of the second through hole is outward.

As a result, inward burrs 15 and outward burrs 16 are formed.Water flowing from the water supply pipe 3 is effectively stirred by the inward burrs 15, and is scattered and scattered. Can easily flow out from the through hole 2 a of the outward burr 16.

In each of the above embodiments, the axis of the blower motor M, the blower fan F, and the fine mist generator 9 are shared by one shaft 1, but as shown in FIG. The pulley P1 on the motor side is fixed to the output shaft 1m, the pulley P2 is fixed to the common shaft 1f of the fan F and the fine fog generator 9, and the two pulleys P1 and P2 are connected by the belt 20. May be.

Or, as shown in Fig. 6 (2), separate the fan shaft 1f and the shaft 19 of the fine mist generator 9 and fix the pulleys P3 and P4 respectively. The pulleys P5 and P6 having different outer diameters are fixed to the output shaft lm of the motor M, and the pulleys P5 and P3 are connected by the belt 21 and the pulleys P6 and P4 are connected by the belt. 22 can also be connected. In this case, a single motor M is used as the drive source, and the diameter of each pulley P3 to P6 is selected.

The rotation speed of the fan F and the fine fog generator 9 can be set freely. FIG. 7 shows an embodiment in which the fan F and the fine mist generator 9 are driven by separate modules Ml and M2. That is, the fan F is driven by the fan motor M1, and the fine fog generator 9 is driven by the dedicated motor M2. The fine mist generator 9 in FIGS. 6 and 7 has almost the same structure as the fine mist generator 9 in FIGS. 1 to 4, and has a structure in which the length L is shorter than the diameter D. There is no problem if the fine mist generator 9 is put out before the cylindrical guard 5 as shown in Fig. 1, but as shown in Figs. 2, 3 and 7, the fine mist generator 9 If it is retracted from the tip of the guard 5, the mist atomized by centrifugal force may hit the inner wall of the guard 5 and collect at the lower part 5a of the guard, forming a pool of water.

In such a case, as shown in Fig. 7, horizontal fins 23 are fixed to the inner wall of guard 5 at circumferential intervals, and the tips of each fin 23 are turned downward. If this is done, the water dripping from the tip of each fin 23 will be blown off by the wind power of fan F, so that almost no water pool will occur.

As shown in Fig. 6 (2) and Fig. 7, when the rotation speed of the fan F and the fine mist generator 9 can be set independently, the rotation speed of the fine mist generator 9 is higher than that of the fan. By making the fog much higher, fine fog can be generated more efficiently.

As described above, the fine mist generator having the rotary cylinder structure according to the present invention is combined with the blower fan F driven by the motor, and the water supply pipe tip 3a is inserted into the rotary cylinder 2 to supply water. By rotating the cylindrical body 2, water is scattered outward by centrifugal force from a large number of through holes in the peripheral wall of the cylindrical body 2, and

A large amount of fine fog can be generated by passing through the rotating structure or fixed structure net 4, 7, 8 or 11 disposed outside the peripheral wall of 2. Then, by blowing air in one direction with the blower fan F,

/ 3 Fog can be sprayed over a wide area such as a mouse. In a small area, the mist can be generated by the centrifugal force and the mist can be sprayed only by the fine mist generator 9 having the rotating cylinder structure without using the blower fan F.

(Spray device with impeller structure)

The embodiment shown in FIGS. 8 to 13 is a spray device suitable for high-speed rotation. FIG. 8 shows a single type, in which a plurality of blades 26 extending in the outer peripheral direction from the center are interposed and fixed in a space between opposing disks 24 and 25 arranged opposite to each other. _c and you have configured impeller 2 7 in the center of the opposite disc 2 4 one, is fixed to the output shaft of the motor M 2. The center of the other opposed disk 25 is provided with an opening 28 for water supply. Therefore, when water is supplied with the water pipe end 3a facing the opening 28, the water is blown off radially from the space 29 between the adjacent blades 26 and 26 by centrifugal force. At this time, when the rotation speed of the impeller 27 is as high as, for example, 10,000 or more, the impeller becomes fine fog.

That is, when the impeller 27 rotates at high speed in the direction of the arrow a1 (left rotation in the figure), the water supplied from the opening 28 moves outward along the front surface 26a of the impeller 26, and finally, The blade 26 is swung in the direction of the arrow 2 by centrifugal force from the outer end of the blade 26. Such a moving force is performed at a high speed, so that when it scatters in the direction of the arrow 2, it becomes mist-like.

Also, the fog scattered in the direction of arrow a2 is blown away by centrifugal force, so that the reaching distance becomes longer. As a result, as shown in Fig. 11 and Fig. 12, when the rotation axis is vertical, fog scatters in the horizontal direction, so that only impeller 27 generates fine fog and sends fog. It works well as a spray device.

A wall or a net 39 is disposed outside the outer periphery of the impeller 27 at a distance A so as to surround the impeller 27. Therefore, arrow a 2 way

I The fog scattered in the direction is blasted vigorously by the centrifugal force, collides with the wall or the net-like body 39, and scatters in all directions to form a finer mist.

Further, when the above-mentioned blowing fan F is used in combination, fine fog inside the wall portion or the reticulated body 39 can be blown in one direction.

A plurality of obstruction members 40 are provided so that water introduced from the opening 28 into the space 29 between the opposed disks 24 and 25 collides by centrifugal force. The baffle member 40 may have a length such that both ends reach and are supported by the opposing disks 2 and 25, as in a baffle member 40a shown in FIG. 8 (1). As in b, the length may be fixed to one of the opposed disks 24 and not reach the other opposed disk 25.

Alternatively, as in the case of 40 c, the length may be fixed to the other opposed disk 25 side and not reach one of the opposed disks 24. Further, a structure in which any two or three of these three types are mixed regularly or randomly may be used. The cross-sectional shape of each of the baffle members 40a, 40b, and 40c can be any shape such as a circle, a square, a star, and a plate.

Thus, when the baffle member 40 is provided, the water introduced from the opening 28 becomes fine mist when it collides with each baffle member 40 by centrifugal force and scatters, so that the impeller 27 rotates. Even when the number rotates at a relatively low speed, atomization can be effectively performed.

FIG. 9 shows an embodiment in which the impeller 27 of FIG. 8 is integrated back to back, and the center of the intermediate disk 24 is fixed to the output shaft of the motor M2. In the center of the middle disk 24, a window hole 30 is opened between the connecting portion 24a to the motor shaft, and about half of the water supplied from the water supply pipe end 3a is supplied to the window hole. From 30 go into the left impeller 27a and the other half into the right impeller 27b.

The motor shaft is fixed to the center of the left disk 25a, and the middle disk

/ ί ~ The center of 24 can be a circular opening.

In FIG. 8 (2), the blades 26 are arc-shaped, but the shape is not limited as long as it can be atomized efficiently by centrifugal force. The distance between the disk 24 and the disks 25, 25a and 25b is large at the center and narrow at the outer periphery to increase the atomization efficiency, but is not limited to this structure. . Therefore, it is possible to increase the distance B between the opposed disks 24 and 25 (25a, 25b) to a size approximately equal to or larger than the radius of the impeller 27.

FIG. 10 shows a structure in which the above-mentioned disks 25, 25, 25a, 25b are formed in a bowl shape, and are stacked in the same direction at intervals. That is, the bowls 3 la, 3 1b, 31 c, 31 d are arranged at equal intervals d or different intervals, and the same as in Figs. 8 and 9 between them. The wings 26 are fixed.

At the center of each bowl 3 la, 3 1b, 3 1c, 3 1d, a water supply cylinder 32 is inserted and fixed.The output shaft of the motor M2 is fixed at the center of one end of the cylinder 32. Is fixed, the tip 3a of the water supply pipe is arranged at the other end of the cylinder, and water is supplied into the cylinder 32. Since a large number of holes 33 are formed in the outer peripheral wall of the cylinder 32, water is uniformly supplied to the space between the bowls 3 la, 31b, 31c and 31d by centrifugal force. You.

When the bowl-shaped bodies 3 la, 3 1 b, 31 c, and 31 d are used as in this embodiment, the fog that has been shaken off from these outer peripheral ends is in the direction of the arrow a 3, that is, obliquely forward. Fog is sent. Therefore, even if there is no blower fan F, it can be sprayed to the target place. If the fan F is used together, the mist can be blown farther.

In this way, by reducing the number of bowls 31a, 31b, 31c, and 31d or reducing the number of blades 26, finer fog is produced in larger quantities.

I et al Can be generated.

10, the motor M2 can be connected to the right end of the cylinder 32, and the water supply pipe 3a can be provided at the left end.

When the impeller with the impeller shown in FIGS. 8 to 10 is used in combination with a blower fan, it may be rotated by the same drive source as the blower, as shown in FIG. As shown in FIG. 7, it may be rotated by a drive source M 2 different from the blower.

In each of the above embodiments, the blower fan F has a structure in which the spray is concentrated in a predetermined area, but the spray device can swing up and down and right and left, or rotate around a vertical axis. With this structure, it is possible to spray over a wider area.

FIG. 11 and FIG. 12 show an embodiment of a structure for spraying in all directions. That is, the impeller 27 in FIGS. 8 and 9 is installed at the center of the upper disk 34 with its rotation axis standing in the vertical direction. The water pipe tip 3a is arranged downward at the upper center of the impeller 27.

The upper disc 34 is supported on a funnel-shaped lower disc 35 by a column 37, and a cylindrical casing 36 is set up below a central circular opening 35a. A fan F and a fan motor Ml are provided in the casing 36. Therefore, when the fan F rotates, the air entering from the lower air intake 36a on the casing 36 gushes in the radial direction from the space between the upper and lower disks 34, 35 and the arrow a Generates wind in four directions.

The fine mist generated in the direction of arrow a4 by the impeller 27 rotated at high speed by the motor M2 is blown off horizontally and 360 ° in all directions by centrifugal force. The blown-off fog is sent farther on the wind in the direction of arrow a4. Therefore, if this device is installed and operated in the center of a field or the like, it is possible to send fog to the entire area outside the spray device.

The distance between the upper and lower disks 34, 35 is made larger toward the center and narrower toward the outer periphery to prevent the speed of the wind generated by the fan F from decreasing.

Fig. 12 shows that the impeller 27 is built in the space between the upper and lower disks 34 and 35 in Fig. 11, and the inverted cone-shaped guide 38 is supported by the column 37a. A motor M2 for driving the impeller 27 is mounted and fixed thereon. The wind generated by the blower fan F is smoothly guided by the guide 38 in the outer circumferential direction, so that the blown wind can be efficiently increased. It should be noted that two sets of blowing means may be provided symmetrically with the impeller 27 interposed therebetween. The impeller 40 (40a, 40b.40c) is omitted from the impeller 27 shown in FIGS. 9 to 12, but the cross section has an arbitrary shape and an arbitrary length. The same effect as in the case of Fig. 8 can be obtained by arranging the baffle member at an arbitrary position to increase the effect of generating fine fog.

The impellers in FIGS. 8 to 10 can be manufactured even if the disks 24, 25, 25a, 25b and the blades 26 are formed as a single component and then combined later. 13 As shown in Fig. 3, one disk 24 and each blade 26a are integrally molded with resin, and the other disk 25 in Fig. 8 is screwed or bonded to the blade 26a. It is also possible to fix with, for example. That is, regardless of the manufacturing method.

Also, as shown in Fig. 8 (2), the distance between the blades 26 is wider than the outer circumference, but one more blade must be added between the blades 26. Thus, as shown in FIG. 13, the outer peripheral side can be prevented from becoming too wide.

The fan F in each of the above embodiments is not limited to the illustrated structure, and various fans such as a sirocco fan, an evening fan, a duct fan, and a household fan can be used.

ί 2 As described above, the water supplied to the center of rotation of the impeller is scattered by centrifugal force to be atomized, and then the scattered fine mist is blown in a desired direction by a blowing means to grow the cultivation. It can be used not only for the house but also for cooling the animals by spraying them in the barn to protect the animals from extreme heat.

Furthermore, in winter, if a large amount of fine fog is generated by supplying water that is hotter than the atmosphere, it is possible to heat the surrounding air and heat it. Available.

Efficient by generating and supplying a large amount of fine fog, not only in houses and barns, but also outdoors, where low temperature areas are created in summer and high temperature areas are created in winter. The purpose can be realized at low cost.

Detectors such as a temperature sensor and a humidity sensor are installed, and the system is configured to control the operation of water supply control equipment such as a solenoid valve based on the detection signal. Can also be planned.

It can also be used for spraying pesticides by atomizing a liquid that has been disintegrated. Alternatively, it can also be used to prevent salt damage by spraying water onto crops that have been covered with salt due to typhoons or the like. Industrial applicability

1. Since the tip of the water supply pipe 3 can be inserted from the opening 2c of the cylinder 2 attached to the rotary drive shaft 1, a large amount of water can be continuously supplied into the cylinder 2. Then, water is scattered by centrifugal force from a large number of through-holes 2 a in the peripheral wall of the cylindrical body 2, and collides with the nets 4, 7, 8, 11, etc. on the outer side to generate a large amount of fine fog. Can be. In addition, since water can be supplied using ordinary water supply, no special pressure generating device is required unlike a spray nozzle, and equipment and running costs can be reduced. 2. A plurality of meshes are arranged concentrically on the outside of the cylinder 2, and the mesh on the inside is made coarser and the mesh on the outside is made finer, so that it is more efficient and more reliable. Fog can be generated.

3. By using a spraying cylinder and a blower fan together, it is possible to spray farther and in a specific area. In addition, the driving force of the blower fan F can be shared with the drive of the sprayer by adopting a structure in which the shaft for rotating the atomizer and the shaft of the blower fan F rotate integrally. However, since no special drive source is required, it can be realized at low cost. By rotating the cylinder with a drive source different from that of the blower fan F, it is possible to freely set the rotation speeds of the spraying cylinder 2 and the blower fan.

4. By providing the rotating fins 10 on the outer periphery of the cylindrical body 2 to increase the chance of water droplets to rebound, fine mist can be generated smoothly and reliably. In addition, it collides with the tape-shaped or arc-shaped net 13 having a fine mesh, and is atomized more finely and guided to a target place.

5. A plurality of blades extending from the center to the outer periphery are provided in the space between the opposed disks, and when water is supplied to the center, fine mist can be generated efficiently by centrifugal force due to the rotation of the plurality of blades. Because of the large centrifugal force, the centrifugal force can spray a wider and farther area.

6. If the shaft of the impeller is connected to the same drive source as the blower or another drive source, and the structure that uses the blower is used,

It can spray over a wide area.

7. If the opposing disk is bowl-shaped, it will be guided in the direction of the opening of the bowl-shaped body and will be sprayed, so it can be sprayed toward the target place without a blower, and if it is used together, Sprays farther.

8. Since a plurality of obstructing members are arranged in the space between the opposed disks so that water flows in from the water supply port and collides with water, it is provided at the center of the opposed disk.

XO When the supplied water scatters by the centrifugal force, it repeatedly collides with the obstructing member and scatters, and becomes fine particles inside the impeller. Further, since the particles are scattered outward by the centrifugal force of the impeller, the mist becomes finer. Moreover, the fine mist bounced off by the obstruction member scatters in various directions from the outer periphery of the impeller, so that when the fine mist is released from the impeller, the mist becomes finer.

9. By setting the rotation axis of the spray device to be vertical, the spray can be sprayed horizontally and 360 ° in all directions, and can be sprayed farther by the wind force in the radial direction. Therefore, it can be sprayed over a wider area with one unit by installing or moving it in the center of the field.

10. Efficiently generate fine mist by centrifugal force and then spray by blowing means to spray more distantly, to control the temperature by spraying over a wide area, and to spray pesticides. And the salt attached to the crops can be washed off or sprinkled, and the use of the spray device can be expanded.
