Further, the present invention provides a bypass flow path that flows directly from the upper end of the nozzle shaft to the lower injection port through the hollow portion, thereby adjusting the amount of the high-pressure fluid passing through the turbine of the nozzle shaft and the amount of the high- To a nozzle assembly capable of adjusting the rotational speed of the shaft.

Further, the present invention relates to a fluid ejection apparatus for ejecting fluid while mounting a plurality of the nozzle assemblies and rotating the nozzle assembly.

The nozzles have been used for a long period of time for spraying fluids, and their applications are also very diverse. Particularly, the nozzle for fluid spraying is widely used for paint spraying for painting, pesticide spraying, washing water spraying, spraying water for plant cultivation, and high-pressure air spraying for cleaning.

Among them, conventional techniques for rotating the nozzle have been developed to spray the fluid evenly over a large area.

As shown in FIG. 10, in Korean Patent No. 10-1028218 filed on June 23, 2010 (hereinafter referred to as "Prior Art 1"), by a spraying force for spraying a high-pressure fluid such as high- Discloses a technique of rotating a body of an injection tube (which means a rotating body in which a plurality of nozzles are integrally coupled and rotating, hereinafter referred to as a "main body") by generating a rotating torque.

In Korean Patent No. 10-1445556 (filing date 2014.02.11) (hereinafter referred to as "Prior Art 2"), as disclosed in FIG. 11, the fluid introduced into the nozzle assembly is divided into three nozzles A rotation torque is generated in a rotary distribution portion (a rotating body in which a plurality of nozzles are integrally coupled and rotated by a jetting angle of a nozzle, that is, a spraying direction of a fluid) Thereby rotating the nozzle.

However, in the prior arts 1 and 2, the rotating body integrally coupled with a plurality of nozzles, that is, the technical structure for rotating the main body, does not rotate the nozzle itself. Furthermore, in the prior arts 1 and 2, when the plane perpendicular to the rotation axis of the main body is taken as a reference, the injection position of the fluid is arranged as far as possible from the rotation center point and the injection direction of the fluid is also set in the normal direction with respect to the rotation center point There is a limitation in that a large rotational torque can be obtained.

Furthermore, it is not easy to adjust the rotation speed of the main body of the related art 1 and the conventional art 2. Decreasing the injection pressure of the fluid can lower the rotation speed of the main body, but the injection amount per unit time is reduced and the jet range of the fluid ejected from the nozzle tip is also reduced.

The reference numerals shown in Figs. 10 and 11 are not related to the present invention.

And includes a nozzle holder 76 and a lower holder 74. The nozzle holder 76 includes a nozzle shaft 76 having a jet opening at a lower end thereof and rotatably mounted on the inner periphery of the upper holder and the lower holder.

5 to 8, the fluid ejection apparatus of the present invention includes:

And a main body 30 to which a plurality of the nozzle assemblies 70 are coupled.

Hereinafter, a description will be given of the nozzle assembly 70, which is one of the main points of the present invention. Next, the features of the main body 30, which is another core of the present invention, will be described.

The nozzle assembly 70 of the present invention includes a cylindrical upper holder 72 and a lower holder 74 having the same central axis as shown in Figs. 2-4. The lower end of the upper holder 72 and the upper end of the lower holder 74 are screwed together and the inner space formed by the two holders 72, And a nozzle axis 76 rotatably provided with the same center axis as the nozzle axis 76. [

The jet opening 764 provided at the lower end of the nozzle shaft 76 is exposed to the outside of the lower holder 74 through the opening 743 formed at the lower end of the lower holder 74, Do not interfere with the holder.

A guide member 73 is provided in the upper holder 72. The guide member 73 has a hollow circular plate shape sandwiched between an upper portion of the nozzle shaft 76 and an inner surface of the upper holder 72 and has a plurality of guide holes 733 through which the fluid passes. A bearing 79 is interposed between the inner circumferential surface of the guide member 73 and the upper side of the nozzle shaft 76 to support the nozzle shaft 76 so that the nozzle shaft 76 can rotate stably, The outer circumferential surface is fixed to the inner surface of the upper holder 72.

A nozzle turbine (77) is integrally coupled to the nozzle shaft on the outer surface of the nozzle shaft (76). The fluid descending in the center axial direction while passing through the guide hole 733 of the guide member 73 strikes the nozzle turbine 77 formed on the outer surface of the nozzle shaft 76. By this impact force, The nozzle shaft 77 and the nozzle shaft 76 rotate integrally.

The nozzle shaft 76 is provided with a through hole 763 through which the fluid after hitting the nozzle turbine 77 passes through the hollow portion 762 of the nozzle shaft 76. The fluid after the nozzle shaft 76 is rotated while hitting the nozzle turbine 77 is guided to the hollow portion 762 of the nozzle shaft 76 through the through hole 763 provided in the nozzle shaft 76 And flows out to the jetting port 764.

At this time, the fluid after rotating the nozzle turbine 77 flows into the rotating nozzle shaft 76 through the through-hole 763 and is injected through the injection port 764. The flow of this fluid is shown by arrows in [A] of Fig.

Next, in the nozzle assembly of the present invention, a configuration for adjusting the rotation speed of the nozzle shaft 76 may be such that a rotation speed adjusting hole 765 is formed on the nozzle shaft 76, And a rotation speed regulating opening 78 for controlling the degree of opening and closing of the hole 765.

The upper end of the nozzle shaft 76 is provided with a headless bolt 78 screwed on the center axis of the nozzle shaft 76 so that the rotation speed adjusting hole 765 The opening or closing degree can be adjusted. The tongue bolt has a configuration for adjusting the opening / closing degree of the rotation speed adjusting hole 765, and hence the rotating tongue bolt will be referred to as a 'rotation speed adjusting port 78' hereinafter.

The nozzle assembly according to the present invention having the above-described structure is configured such that the rotation speed regulating opening 78 is unlocked to open the rotation speed regulating hole 765, as shown in the flow of the fluid shown by arrows in [B] , It works as follows.
