[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rotating wave nozzle, mainly a draining device, a drying device, a dust removing device, a cleaning device, a deposit peeling device, a fluid spraying, a stirring device, a massage device using air or water wave, a lake, a river, and a seabed. The present invention relates to a rotating wave nozzle used as a state-of-the-art injection section (header) such as a mud drilling device.
[0002]
[Prior art]
The rotating wave nozzle 100 shown in FIG. 12 is formed in a trumpet shape in which a cylinder body 101 gradually increases in diameter from a base end 101a toward a tip end 101b, and a hose tube 105 is disposed inside the cylinder body 101. The base end 105a of the hose tube 105 is communicated with an air supply source (not shown) on the base end 101a side.
[0003]
By supplying air from an air supply source as indicated by an arrow, air flows into the hose tube 105 from the base end 105a side of the hose tube 105 and is injected from the outlet 105b of the hose tube 105.
By the injection of air from the outlet 105b of the hose tube 105, the hose tube 105 is deformed into a curved shape by the thrust of the injection pressure, and the weight 106 attached to the hose tube 105 abuts against the inner wall 102 of the cylindrical body 101. Become.
[0004]
Thereby, the front-end | tip part 105c of the hose tube 105 shifts | deviates from the extension line | wire of a hose tube, and becomes diagonal, and the hose tube 105 rotates in the arrow direction with the thrust of the injection pressure of the blower outlet 105b.
For this reason, the air with a rotation wave can be injected on a predetermined | prescribed circumference, and this rotation wave nozzle 100 can be used as a draining device, a drying apparatus, or a dust removal apparatus, for example.
[0005]
This rotating wave nozzle 100 is easy to rotate even at low pressure because the hose tube which is a rotating body is lightweight, and because the hose tube 105 and the inner wall 102 of the protective cylinder 101 are always rotating while in contact with each other, Even in the high pressure region, it has a function that prevents the rotational speed from increasing abnormally due to an increase in frictional resistance. At present, the nozzle can generate a stable rotational wave (intermittent shock wave) in the widest range of pressures.
[0006]
However, the hose tube 105 is deformed into a curved shape due to the influence of the thrust of the air injection, and the weight 106 attached to the hose tube 105 abuts against the inner wall 102 of the cylindrical body 101. When rotating along the inner wall 102, as shown in FIG. 13, the inner wall portion 102a of the cylindrical body with which the weight 106 abuts is worn, and further, the portion 105d of the hose tube 105 contacting the inner wall 102 of the cylindrical body is worn.
[0007]
In general, in facilities such as draining and dust removal, it is efficient to guide the removed water or dust removal in a certain direction and form a flow directed to a discharge portion provided at a predetermined position for the convenience of work. In the rotating wave nosle 100, it is difficult to make the direction in which the hose tube bends due to the thrust of the air injection at the time of start-up due to bending or drooping of the tube or resistance from the outside, and in which direction does it rotate to the left or right? The prediction (designation) was not possible. For this reason, there are problems that wave nozzles arranged at equal intervals interfere with each other, and water and dust are scattered irregularly on the left and right to wet or soil the equipment structure and surroundings.
[0008]
Further, the hose tube 105 is automatically deformed into a curved shape by the thrust of air injection, so that the front end portion 105c of the hose tube 105 contacts the inner wall 102 of the cylinder 101. In this state, the hose tube 105 is When rotating along the inner wall 102 of 101, the portion 105d of the hose tube that is in contact with the inner wall 102 is worn.
As described above, in the conventional nozzle, the portions 102a and 105d of the cylindrical body 101 and the hose tube 105 are worn, and thus there is a problem that the durability of the rotating wave nozzle 100 cannot be sufficiently ensured.
[0009]
Further, when the cylindrical body 101 and the hose tube 105 are worn, powder (abrasion powder) is generated by the wear, and the hose tube 105 is broken when the wear further proceeds. It could not be used in a production line for food, medicine, printing, electronic parts, etc. that would not be admixed with foreign matter, or in a clean room.
[0010]
As a solution to such a problem, a rotating wave nozzle 110 having another structure shown in FIG. 14 is also known.
In the rotating wave nozzle 110, the upper end 111a of the rotating shaft 111 is rotatably attached to the safety cover 112, and the nozzle 114 is inclined and fixed to the lower end 111b of the rotating shaft 111 at an appropriate angle via the connection channel 113. ing. When air is ejected from the nozzle 114, the rotating shaft 111 rotates in the direction of the arrow by the thrust of the air ejection.
[0011]
According to this rotating wave nozzle 110, since the rotating shaft 111 is covered with the safety cover 112, the nozzle 114 is not in contact with the safety cover 112, and the hose is rotated like the rotating wave nozzle 100 of FIGS. The tube 105 is not worn, so that the hose tube 105 can be prevented from being broken.
[0012]
A rotating wave nozzle 120 shown in FIG. 15 is also known as another rotating wave nozzle. The rotating wave nozzle 120 has an upper end of a rotating shaft 121 rotatably attached to a support member (not shown), and the nozzle 124 is placed at an appropriate angle via a connecting channel 123 to a lower end 121b of the rotating shaft 121. Tilt is fixed. When air is injected from the nozzle 124, the rotating shaft 121 rotates in the direction of the arrow by the thrust of the air injection.
[0013]
According to this rotating wave nozzle 120, since the rotating shaft 121 is rotatably supported by a support member (not shown), the hose tube 105 may be worn like the rotating wave nozzle 100 of FIGS. Therefore, the situation where the hose tube 105 is broken can be avoided.
[0014]
[Problems to be solved by the invention]
In general, in order to start rotating a rotary nozzle using the rotary wave nozzles 110 and 120 at a low pressure, it is necessary to set the inclination angle θ of the nozzles 114 and 124 small. However, if the rotational wave nozzle is used in this state in the high pressure region, the rotational speed increases and the effect of the rotational wave is easily lost beyond the ideal rotational speed. This is because the pitch of the rotating vortex flows becomes small and the wave flow changes to a flow close to a steady flow, and the rotating vortex flows too far outward and the force applied in the vertical direction becomes weak. is there. Furthermore, since the pitch of the rotating vortex is reduced and the rotating flow path is expanded outward, the wave attenuation rate with respect to the distance to the workpiece is also increased.
[0015]
For these reasons, the effect of intermittent shock waves cannot be obtained in the high pressure region. Therefore, when used in the high pressure region, it is necessary to change the inclination angle of the nozzles 114 and 124 to an appropriate angle θ (θ = 90 ° or less within the acute angle range) by changing the pressure. In order to perform this fine adjustment, it is necessary to stop the work, or a technique is required for the fine adjustment, so the work is difficult or takes time. For this reason, there was a strong demand for a significant improvement in terms of usability.
[0016]
This invention can ensure sufficient durability and can also be used in the production line of food and electronic components. Further, when the air injection pressure injected from the nozzle changes, the rotation speed of the nozzle is suitable. It is an object of the present invention to provide a rotating wave nozzle having a function that can be maintained in a certain region to solve all the above-mentioned problems.
[0017]
[Means for Solving the Problems]
In order to achieve the above object, according to a first aspect of the present invention, a support portion is formed at an end portion of the rotating wave nozzle, and a first air flow path capable of communicating with an air supply source is formed in the support portion. The base end of the rotary shaft is rotatably attached to the first air flow path of the support portion, the second air flow path drilled in the rotary shaft is communicated, and a hose tube connection port is formed on the peripheral wall of the rotary shaft. A rotating disk is attached to the tip of the rotating shaft, a flexible hose tube is connected to the hose tube connection port, a through hole is formed in the rotating disk, and the air outlet of the hose tube is connected to the hose tube outlet. The safety cover that can cover the inner side of the rotating shaft, the hose tube, and the rotating disk by allowing the air outlet of the hose tube to face the outer surface of the rotating disk by passing the through hole from the inner side to the outer side of the rotating disk. A rotating wave nozzle attached to the holding portion, wherein the hose tube outlet is inclined with respect to the rotating disk so that the rotating disk can be rotated by thrust at the time of air injection from the hose tube outlet In addition, the tip of the hose tube is attached to the rotating disk so that the angle of the air outlet of the hose tube automatically changes depending on the change in the internal pressure of the hose tube.
[0018]
According to the above-described rotating wave nozzle according to the present invention, the air from the air supply source is injected from the air outlet of the hose tube, and the rotating disk rotates about the rotating shaft as the central axis using the thrust of the air injection. Therefore, there is no worry that the cylindrical body of the rotating wave nozzle and the hose tube are worn as in the prior art.
[0019]
Furthermore, since the cylindrical body and hose tube of the rotating wave nozzle do not wear, it is possible to suppress the generation of abrasion powder, and the rotating wave nozzle can be used in production lines for food, chemicals, printing, electronic parts, etc. Can be used in a clean room.
[0020]
Also, by automatically adjusting the air injection angle, it becomes easy to rotate even with a small flow rate, and with a large flow rate, an excessive increase in the rotational speed can be suppressed, and a function that can maintain the rotational speed in a suitable region is provided. Yes. Therefore, the rotating wave nozzle can be used under suitable conditions without taking time and effort.
[0021]
According to a second aspect of the present invention, a through hole is formed in the rotating disk so as to penetrate the outlet of the hose tube, and a flap for supporting the vicinity of the tip of the hose tube is provided in the vicinity of the through hole.
[0022]
By supporting the vicinity of the tip of the hose tube with a flap, the outlet of the hose tube can be disposed at a predetermined inclination angle with a simple configuration.
[0023]
According to a third aspect of the present invention, the flap is formed of a restoring member capable of changing an inclination angle, and a bent twist portion is formed at one or a plurality of locations of the hose tube.
[0024]
When the flap is formed of a recoverable member that can change the tilt angle, the hose tube is made flexible, and the bent twisted part is formed in one or more places of the hose tube, the internal pressure of the hose tube increases. The tension of the hose tube increases, and the force that the hose tube extends linearly works. This force is the force that raises the hose tube outlet in the vertical direction, and the flap itself can elastically deform and rise up in the vertical direction, increasing the inclination angle of the hose tube outlet and suppressing the rotation of the rotating disk be able to.
[0025]
On the other hand, as the internal pressure of the hose tube decreases, the tension of the hose tube gradually decreases, and the original twisted initial shape is restored. At the same time, the elastically deformable flaps pulled in the vertical direction gradually return to the initial inclined state, and are restored to the original state in which an ideal nozzle rotation speed can be secured even with a small flow rate.
[0026]
According to a fourth aspect of the present invention, the position immediately above the hose tube where the tip of the hose tube is supported by a flap is twisted outward.
[0027]
The front end plate of the hose tube that is supported by the flap is twisted outward because the tip of the hose tube is twisted to the outside. When the internal pressure of the hose tube increases, the force that the hose tube tries to extend linearly becomes more efficient. Thus, the force for raising the outlet of the hose tube in the vertical direction can be obtained more effectively.
[0028]
In addition, when the internal pressure of the hose tube decreases and the tension of the hose tube decreases, the force that restores the initial shape to the hose tube works, so the outlet of the hose tube tilts in a direction that reduces the inclination angle. The ideal nozzle rotation speed can be secured even with a small flow rate.
[0029]
According to a fifth aspect of the present invention, a plurality of the hose tubes are provided.
By using a plurality of hose tubes, the rotating disk can be rotated more smoothly, and more powerful rotational waves can be obtained by the air injected from the hose tube outlet.
[0030]

FIG. 4 is a perspective view of a rotating disk used in the first embodiment with a slit, FIG. 4 is a perspective view of a state in which a flap is formed on the rotating disk, and FIG. 5 is used in the first embodiment of the present invention. FIG. 6 is a perspective view for explaining the operation of the first embodiment of the rotating wave nozzle according to the present invention. FIG. 6 is a side view showing a state where the tip of the hose tube is attached to the flap of the rotating disk.
[0031]
In the rotary wave nozzle 10 of the first embodiment shown in FIGS. 1 and 2, a first air flow path 11 a that can communicate with an air supply source (not shown) is formed in the support portion 11. A bearing 13 is screwed into the threaded portion 12, and a base end 15 a of a rotating shaft 15 is rotatably attached to the bearing 13 via a bearing 14.
Further, the second air flow path 15b of the rotary shaft 15 communicates with the first air flow path 11a of the support portion 11, and a hose tube connection port 18 communicated with the second air flow path 15b is formed on the peripheral wall of the rotation shaft 15. A hose tube 19 is connected to the hose tube connection port 18.
[0032]
A rotating disk 20 is attached to a tip 15c of the rotating shaft 15 with a mounting bolt 21, and a blowout port 19b of the hose tube 19 is passed through the through hole 24 of the rotating disk 20 from the inside to the outside. The air outlet 19 b faces the outside of the rotary disk 20.
By attaching the support portion 11 to the neck portion 25a of the safety cover 25, the inside of the rotary shaft 15, the hose tube 19 and the rotary disc 20 is covered with the safety cover 25, and the opening 25b of the safety cover 25 has a rotary disc. It arrange | positions in the state which the outer side of 20 exposed.
[0033]
A screw portion 15d is formed at the base end 15a of the rotary shaft 15, and fixing nuts 27 and 28 for fixing the bearing 14 are screwed into the screw portion 15d.
[0034]
The rotating wave nozzle 10 is disposed in a state in which the tip end portion 19a of the hose tube 19 is inclined at a predetermined angle θ with respect to the rotating disk 20, and injects air from an air supply source from an outlet 19b of the hose tube 19. Thus, the rotary disk 20 is configured to rotate using the thrust of the air injection.
[0035]
Since the rotary shaft 15 is rotatably attached to the support portion 11 and the tip 19a of the hose tube 19 is inclined at a predetermined angle θ with respect to the rotary disk 20, the air from the air supply source is blown out from the hose tube 19. It is injected from 19b, and the rotary disk 20 can be rotated with the rotary shaft 15 as the central axis.
At this time, the hose tube 19 does not come into contact with the safety cover 25, so that the hose tube 19 and the safety cover 25 are not worn.
[0036]
Since the hose tube 19 and the safety cover 25 are not worn, no abrasion powder is generated. For this reason, even if the rotating wave nozzle 10 is used in a production line for food and electronic parts, the food and electronic parts on the production line are worn. Does not attach powder.
Therefore, the rotational wave nozzle 10 can be used in a clean room such as food and electronic parts, as well as a production line.
[0037]
The material of the safety cover 25 is, for example, a metal such as iron, stainless steel, or aluminum, or a resin such as polyacetal, ABS resin, polypropylene, or vinyl chloride, but is not limited thereto.
Further, the rotating shaft 15 corresponds to, for example, a metal such as iron, stainless steel, and aluminum, or a resin such as polyacetal, but is not limited thereto.
Furthermore, the hose tube 19 corresponds to a general tube of an elastic body such as polyurethane, nylon, silicon, or rubber as an example, but is not limited thereto.
[0038]
A substantially U-shaped slit 22 shown in FIG. 3 is formed in the rotary disk 20, and the slit 22 is raised to form a flap 23. This flap 23 is on the rotary shaft 15 side (inside) as shown in FIG. It can be bent.
As a result, a through hole 24 is formed in the rotary disk 20, and by passing the tip 19a of the hose tube 19 through the through hole 24, the air outlet 19b is exposed to the outside of the rotary disk 20, and the tip of the hose tube. The part 19a is supported by the flap 23 as shown in FIG.
When the hose tube 19 is attached to the flap 23 using the strap 26, the air outlet 19b of the hose tube 19 is supported at a predetermined position with a simple configuration.
[0039]
Since the flap 23 of the rotating disk 20 is formed of a restoring member capable of changing the inclination angle, the inclination angle θ of the flap 23 shown in FIG. 5 can be deformed.
Further, since the hose tube 19 is formed of an elastically deformable flexible member, for example, after the hose tube 19 is extended in parallel with the rotary disk 20 from the hose tube connection port 18 (see FIG. 2), either After being bent and twisted in that direction and then raised upward, the tip 19a of the hose tube 19 is penetrated through the through hole 24 of the rotary disk 20 so as to face downward.
[0040]
For this reason, when the internal pressure of the hose tube 19 increases, the tension of the hose tube 19 increases, and a force that the hose tube 19 tries to extend linearly works, and this force causes the tip 19a of the hose tube 19 to move vertically. Corresponding to the deformation of the hose tube 19, the flap 23 is also elastically deformed and rises to follow the vertical direction. For this reason, the inclination angle θ of the distal end portion 19a is increased, the hose tube approaches a vertical shape, and the rotation of the rotary disk 20 is suppressed.
[0041]
Further, when the internal pressure of the hose tube 19 is lowered, the tension of the hose tube 19 is reduced, and the force for extending the hose tube 19 in a straight line is weakened. Therefore, the hose tube attempts to restore the original state. This restoring force becomes a force for inclining the tip 19a of the hose tube 19, and the flap 23 similarly attempts to restore to the initial setting state. Therefore, the inclination angle θ of the tip 19a of the hose tube becomes small and inclines. Since it tilts, the rotating disk 20 is in a state of increasing rotation.
[0042]
Thereby, the number of rotations of the rotating disk 20 is automatically adjusted in accordance with the injection pressure of the air injected from the air outlet 19b of the hose tube 19. Thus, the rotational wave nozzle 10 automatically adjusts the air injection angle of the air outlet 19b of the hose tube 19 in accordance with the air injection pressure so that the rotating disk 20 has a predetermined rotational speed. It can be adjusted.
[0043]
Moreover, if the rotation wave nozzle 10 comprises the hose tube 19 by one, the hose tube 19 can be made a simple structure and the cost of the rotation wave nozzle 10 can be suppressed.
[0044]
Next, the operation of the rotating wave nozzle 10 will be described with reference to FIGS. As shown in FIG. 2, when the rotary shaft 15 is rotatably attached to the support portion 11 and the tip portion 19a of the hose tube 19 is inclined at a predetermined angle with respect to the rotary disc 20, the first air of the support portion 11 is supplied from the air supply source. Since air is supplied into the flow path 11a as indicated by an arrow, the air supplied into the first air flow path 11a passes through the second air flow path 15b of the rotating shaft 15 and the hose tube connection port 18 to form a hose. It flows into the tube 19 and is finally ejected from the outlet 19b of the hose tube 19.
[0045]
As a result, as shown in FIG. 6, by utilizing the thrust of air injection, the rotating disk 20 rotates in the direction of the arrow with the rotating shaft 15 as the central axis, and the air is evenly distributed on the circumference over a predetermined area. This rotational wave nozzle can be used in the above-described usage example.
[0046]
Here, when the injection pressure of the air injected from the air outlet 19b of the hose tube 19 increases, the internal pressure of the hose tube increases, and the hose tube 19 shown in FIG. The vicinity of the tip portion is linear, and a curved wrinkle appears at a part of the bent twisted portion in front of it. As shown in FIG. 5, the flap 23 is elastically deformed so that the inclination angle θ of the flap 23 is increased. Become bigger.
For this reason, the inclination angle of the front end portion 19a of the hose tube 19 also increases and approaches a vertical shape, and the rotational speed of the rotating disk 20 decreases.
[0047]
On the other hand, when the injection pressure of the air injected from the air outlet 19b of the hose tube 19 decreases, the internal pressure of the hose tube decreases, and the hose tube 19 shown in FIG. Since the wrinkle is reduced and the flap 23 is elastically deformed and returns to the initial setting state as shown in FIG. 5, the inclination angle θ of the front end portion 19a of the flap 23 is reduced, and the hose tube is inclined to incline. No. 20 can maintain the rotational force even when the injection pressure is low.
In this manner, the rotating wave nozzle 10 that automatically adjusts the rotation speed of the rotating disk 20 in accordance with the air injection pressure can be obtained with a simple configuration.
[0048]
In addition, since the rotating disk 20 demonstrated above has also played the role of the flywheel, the rotation becomes smooth.
Furthermore, when the rotating disk 20 is mounted with the front and back reversed, the rotating disk can be rotated in the reverse direction.
[0049]
Next, second to fifth embodiments will be described.
In the second to fifth embodiments, the same members as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. First, a second embodiment will be described with reference to FIG.
The rotating wave nozzle 30 of the second embodiment shown in FIG. 7 is different from the first embodiment only in that the number of hose tubes 19 is two, and the other configuration is the same as that of the first embodiment.
[0050]
By using a plurality of hose tubes 19 (two as an example), rotation of the rotary disk 20 can be made smoother, and higher frequency rotational waves can be generated by air jetted from the hose tube outlet. Obtainable.
Furthermore, when the inclination direction of the hose tube outlet is the same, the thrust of the air injection can be doubled, so that the efficiency of the processing work can be improved.
[0051]
When multiple hose tubes are attached, the inclination angle of each hose tube can be changed, and the inclination directions can be opposite to each other. It is possible to determine the direction of rotation with strength and weakness and to obtain a complex rotational wave.
[0052]
Next, a third embodiment will be described with reference to FIGS.
In the rotating wave nozzle 40 of the third embodiment shown in FIG. 8, a through hole 42 is opened in a rotating disk 41, and a flap 43 made of a restoring member capable of changing an inclination angle is attached in the vicinity of the through hole 42. A nozzle 44 is inserted into the through hole 42, and in this state, the nozzle 44 is attached to the flap 43 via upper and lower bands 45 and 46.
As an example, after the hose tube 47 is extended in parallel with the rotary disk 41 from the hose tube connection port 18, the hose tube 47 is bent and twisted in either the left or right direction, and then raised upward, The portion 47a is connected to the upper end 44a of the nozzle 44 in a state where the portion 47a is twisted downward and outward as indicated by an arrow.
[0053]
The upper and lower bands 45 and 46 are made of a material that is soft and easily elastically deformed, and the lower band 46 is made of a material that is hard and hardly elastically deformed. For this reason, in the high-pressure region, the hose tube 47 increases the tension, and thus a force that causes the inclination angle of the nozzle 44 in the vertical direction works. At this time, the lower band 46 becomes a fulcrum, the upper band 45 extends, and the angle of the nozzle 44 is raised in the vertical direction. Further, as the internal pressure of the hose tube 47 becomes lower, the tension gradually decreases to return to the original bent setting shape. Accordingly, the extended upper band 45 is also loosened, and gradually returns to the original tilt angle setting position together with the nozzle 44. This method is effective when the flap 43 is difficult to elastically deform.
[0054]
The tip portion 47a of the hose tube 47 is connected to the upper end 44a of the nozzle 44 in a state of being twisted outward, so that when the internal pressure of the hose tube 47 increases, the force with which the hose tube 47 tends to extend linearly is increased. Work efficiently. For this reason, as shown in FIG. 9, the flap 43 is elastically deformed and the inclination angle θ of the flap 43 is changed, so that the nozzle can be efficiently raised in the vertical direction.
[0055]
Further, since the tip portion 47a of the hose tube 47 is twisted outward before being connected to the upper end 44a of the nozzle 44, when the internal pressure of the hose tube 47 becomes low and the tension of the hose tube 47 decreases. The restoring force to restore to the original state works more efficiently. For this reason, the force which tilts the nozzle 44 in the direction to incline is obtained more effectively.
[0056]
In this way, the rotational speed of the rotating disk 41 can be automatically adjusted in accordance with the injection pressure of the air injected from the outlet 44 b of the nozzle 44, and the rotational wave nozzle 40 is supplied from the outlet 44 b of the nozzle 44. The air injection angle is automatically adjusted in accordance with the air injection pressure.
[0057]
Next, a fourth embodiment will be described with reference to FIG.
In the rotational wave nozzle 50 of the fourth embodiment shown in FIG. 10, a substantially L-shaped bracket 52 is attached in the vicinity of the flap 51, and an adjustment bolt 53 is attached to the upper end of the substantially L-shaped bracket 52. Is locked to the substantially L-shaped bracket 52 by a lock nut 54 so that the tip 53a of the adjustment bolt 53 is brought into contact with the flap 51, and the inclination angle θ of the flap 51 is regulated.
[0058]
Thereby, since the minimum inclination of the nozzle 44 can be set as the predetermined inclination angle θ, the rotational speed of the rotating disk 41 by the thrust of air injection can be set accurately, and the quality of the wave nozzle 50 can be further improved. Can be increased.
[0059]
On the other hand, when the internal pressure of the hose tube 47 is increased, a force for the hose tube 47 to extend linearly acts as in the third embodiment, so that the flap 51 is elastically deformed as in the third embodiment. As the inclination angle θ of the flap 51 changes, the nozzle 44 can be efficiently raised in the vertical direction.
[0060]
Next, a fifth embodiment will be described with reference to FIG.
In the rotating wave nozzle 60 of the fifth embodiment shown in FIG. 11, a substantially L-shaped bracket 62 is attached in the vicinity of the flap 61, and an adjustment bolt 63 is attached to the upper end of the substantially L-shaped bracket 62. Is locked to the substantially L-shaped bracket 62 with a lock nut 64, and the tip 63 a of the adjustment bolt 63 is movably inserted into the through-hole 65 of the tip 61 a of the flap 61 to adjust between the flap 61 and the substantially L-shaped bracket 62. By arranging the compression spring 66 on the bolt 63, the compression spring 66 is configured to regulate the inclination angle θ of the flap 61.
[0061]
As a result, as in the fourth embodiment, the minimum inclination of the nozzle 44 can be set to the predetermined inclination angle θ, so that the rotational speed of the rotating disk 41 by the thrust of air injection can be set accurately. The quality of the rotating wave nozzle 60 can be further improved.
[0062]
On the other hand, when the internal pressure of the hose tube 47 increases, a force is exerted to extend the hose tube 47 in a straight line. Therefore, the flap 61 is elastically deformed and the inclination angle θ of the flap 61 changes as in the third embodiment. By doing so, the nozzle 44 can be efficiently raised in the vertical direction.
[0063]
In addition, although the example which used one or two hose tubes 19 was demonstrated in the said embodiment, it is not restricted to this, The number of the hose tubes 19 can be set arbitrarily.
[0064]
【The invention's effect】
As described above, according to the rotating wave nozzle according to claim 1, since the cylindrical body and the hose tube of the rotating wave nozzle are not worn as in the prior art, it is possible to ensure the durability of the rotating wave nozzle. it can.
[0065]
In addition, since the cylindrical body and hose tube of the rotating wave nozzle are not worn or damaged, no abrasion powder is generated, so this rotating wave nozzle can be used for food, chemicals, printing, It can be used in a production line for electronic parts and the like, as well as in a clean room.
[0066]
Furthermore, by automatically adjusting the air injection angle according to the air injection pressure, the rotation speed of the rotating disk can be maintained in a suitable region, and the rotating wave nozzle can be used under suitable conditions without much effort. There is an effect that can be done.
[0067]
According to the second aspect of the present invention, by supporting the vicinity of the tip of the hose tube with the flap, there is an effect that the outlet of the hose tube can be arranged at a predetermined inclination angle with a simple configuration.
[0068]
According to claim 3, when the internal pressure of the hose tube increases, the tension of the hose tube increases, and the force that the hose tube tends to extend linearly works, and this force becomes the force that causes the outlet of the hose tube to rise in the vertical direction, The flap itself can be elastically deformed to rise up in the vertical direction, and the inclination angle of the outlet of the hose tube can be increased to suppress the rotation of the rotating disk.
[0069]
Furthermore, as the internal pressure of the hose tube decreases, the tension of the hose tube gradually decreases, and the original twisted initial shape is restored. At the same time, the elastically deformable flap that has been pulled in the vertical direction gradually returns to the initial inclined state, and has the effect of restoring the original state in which an ideal nozzle rotation speed can be secured even with a small flow rate.
[0070]
According to a fourth aspect of the present invention, the front end portion of the hose tube supported by the flap is twisted outward so that when the internal pressure of the hose tube increases, the hose tube extends linearly. The force which works more efficiently acts and the force which raises the blower outlet of a hose tube in the perpendicular direction is obtained more effectively.
[0071]
In addition, when the internal pressure of the hose tube decreases and the tension of the hose tube decreases, the force that restores the initial shape to the hose tube works, so the outlet of the hose tube tilts in a direction that reduces the inclination angle. There is an effect that the ideal number of rotations of the nozzle can be secured even with a small flow rate.
[0072]
According to the fifth aspect of the present invention, the rotation of the rotating disk can be made smoother by using a plurality of hose tubes, and more powerful rotational waves can be obtained by the air injected from the hose tube outlet. effective.
