Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray nozzle that rotates while ejecting a fluid, and more particularly, to a spray nozzle that can adjust the angle at which an ejected fluid revolves while rotating and ejects.

[0002]

2. Description of the Related Art A conventional spray nozzle capable of rotating and revolving is schematically described with reference to a cutaway perspective view shown in FIG.
Reference numeral 101 denotes a cylindrical T-shaped main body, which is a main bevel gear 10.
The main shaft 106 to which 6a is fixed is fixed by a cap 102 via an upper bearing 112. Further, the connector 103 forming the cylindrical injection fluid inlet 104 is engaged with and coupled to the main shaft 106.

On the other hand, a sub-bevel gear 116 meshing with the main bevel gear 106a is mounted so that a sub-shaft 118 is perpendicular to the main shaft 106, and a nozzle connector 127 is provided at the right end of the sub-shaft 118. Fixed,
In order to obtain a rotational moment at the tip via the plug 128, a bent (angle θ) injection nozzle 131 is attached.

In the above-described spray nozzle, when a high-pressure fluid flows from the injection fluid inlet 104 while the connector 103 is fixed, the fluid is jetted from the tip of the jet nozzle 131 to generate a rotational moment. By the moment, the sub shaft 118 rotates, and the main body 1 is rotated via the sub bevel gear 116 and the main bevel gear 106a.
01 rotates. That is, the ejection nozzle 131 ejects the fluid while rotating and revolving.

[0005]

Since the spray nozzle sprays in a three-dimensional space, for example, when used in an open tank, the sprayed fluid protrudes from an opening. Therefore, a spray nozzle that can be used for such an open tank is desired.

[0006]

In the spray nozzle according to the first aspect of the present invention, the sub-shaft to which the spray nozzle is attached is attached to the main shaft to which the rotating body is attached.
The injection nozzle revolves while rotating, and for example, can perform cleaning or the like in a state where the injection fluid does not protrude from the open tank. Further, in the spray nozzle according to the second aspect, since the mounting angle of the injection nozzle can be adjusted, the rotation speed of the injection nozzle can be changed by selecting the injection angle.

[0007]

FIG. 1 is a front view of a spray nozzle according to the present embodiment, and FIG. 2 is a sectional view. Hollow part (fluid passage) 6
At the end of the main shaft 6 forming b, a fluid passage 12b is formed, and a sealing member 18 is attached to a mounting body (connector) 12 which connects a fluid pipe connected to a pump (not shown) with a screw 12a.
And screwed with a screw 6c. A main bevel gear 6a is fixed to the lower end of the main shaft 6.

A rotating body (casing) 1 is formed of a vertical cylindrical body 1A made of metal or the like and an inclined (angle 45 °) cylindrical body 1B. An upper bearing 10a and a lower bearing 10b are fitted through a bush 9 in which sealing materials 8a, 8b, 8c for preventing leakage at the inner and outer circumferences are inserted. The rotating body 1 (the cylindrical body 1)
A screw 1a for the fixing cap 7 is formed on the upper outer periphery of A). The bush 9 is mounted in a fitting groove 7 a formed in the fixed cap 7 and screwed and fixed with the screw 1 a, so that the rotating body 1 can rotate with respect to the main shaft 6.

A sub-bevel gear 31, which meshes with the main bevel gear 6a, has a sub-shaft 32 formed with T-shaped hollow portions (fluid passages) 32a, 32b in the cylindrical body 1B of the rotating body 1.
Is fixed at an inclination angle of 45 °. Note that the angle of the jet fluid ejected from the ejection nozzle 43 can be adjusted by this attachment angle. The counter shaft 32 is rotatably supported at the rear by a screw-fixed bearing 33 and is rotatably supported at the front by a bearing 34. The counter shaft 32 is sealed at the rear with an O-ring 38, and a bush 36,
Sealing materials 36a and 37a are fitted via 37 to prevent leakage. At the base of the T-shape of the sub shaft 32, a cleaning cap 42 is screwed and attached.

At the end of the sub shaft 32, a sub shaft 3
An L-shaped (formed at an arbitrary angle) coupling body 44 is rotatably attached to a bolt 4 so as to be capable of adjusting an ejection angle of an ejection nozzle 43 described later via a stop ring 45 fitted and inserted into the bolt 4.
8 and an O-ring 4
6 prevents leakage. Also, the injection nozzle 43
Is screwed to the coupling body 44.

Therefore, the combination 44 and the injection nozzle 4
3, by fixing the coupling body 44 with bolts 48 at an appropriate angle, the rotational moment with respect to the sub-shaft 32 is changed, so that the rotational speed of the injection nozzle 43 can be adjusted. It can be fired at an angle or less.

Next, the use of the spray nozzle will be described. First, a fluid pipe connected to a pump (not shown) is attached to a screw 12a formed on the inner periphery of a connector (attachment main body) 12. And the fluid passage 12 of the connector.
When a fluid (air, water, etc.) flows from b, the fluid flows through the hollow portion 6b of the main shaft, the communication hole 41 of the sub shaft, and the hollow portions 32a, 32a, 3b.
By jetting from the jet nozzle 43 through the fluid passage 2b, a rotational moment is obtained, and the countershaft 32 rotates.

The rotation of the sub shaft 32 rotates the main bevel gear 6a (casing 1) via the sub bevel gear 31, and the injection nozzle 43 injects fluid while revolving with the rotation of the casing 1 together with its rotation. Therefore, when the mounting angle of the injection nozzle 43 is changed, the injection nozzle 4
3 (sub shaft 32) can be adjusted. Also, the mounting angle of the injection nozzle 43 is set to another angle, for example,
Even if the main shaft 6 of the spray nozzle is attached to the open tank in a vertical state (the state of FIG. 1), washing or the like can be performed in a state where the jet fluid does not protrude from the open part of the tank.
The mounting angle (excluding the vertical angle) of the sub shaft 32 with respect to the main shaft 6 is not limited to 45 °, but can be appropriately selected in consideration of the use location. Needless to say, it is not limited.

[0014]

According to the spray nozzle of the first aspect, the auxiliary shaft on which the injection nozzle is mounted is inclined with respect to the main shaft on which the rotating body is mounted, so that the injection nozzle revolves while rotating. For example, cleaning or the like can be performed in a state where the jet fluid does not protrude from the open tank.
In the spray nozzle according to the second aspect, since the mounting angle of the spray nozzle is adjustable, by selecting the spray angle,
The rotation speed of the injection nozzle can be changed.
