BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary nozzle device which can be applied to cleaning various structures, walls, vehicles, etc., spray coating, coating, spraying a chemical solution, and the like.

[0002]

2. Description of the Related Art Conventionally, in various fields, injection nozzles for injecting a desired fluid (for example, cleaning water) liquid onto an object to obtain an injection effect have been widely used. Such an injection nozzle is basically provided by an appropriate pressure feeding means.
The structure is such that the fluid is pressure-fed to the nozzle tip and ejected. In addition, a plurality of such nozzle tips are arranged in parallel on one surface so that the jetting fluid spreads to a certain extent.

[0003]

However, in any case, when the object is wide, it is difficult to give an even jetting effect. For example, in the case of the former single nozzle, it is necessary to take a means for reciprocating while moving the nozzle itself in one direction, so that a complicated driving mechanism is required. Further, even when the operator himself moves it, considerable skill is required and a great deal of labor is required to give an even spray effect. On the other hand, in the latter type having a structure in which a plurality of nozzle tips are arranged in parallel on one surface, although the ejection range is widened, the ejection angle is different between the vicinity of the center of the ejection range and the periphery, so that the ejection effect becomes uneven, After all, it is necessary to repeatedly inject the same portion to some extent. The present invention has been proposed in order to improve the above-described problems, and is a rotary nozzle device that can be applied to cleaning of various structures, wall surfaces, vehicles, etc., spray coating, coating, and the like. The purpose is to provide.

[0004]

In order to solve the above-mentioned problems, the present invention provides a rotary nozzle device in which an ejected fluid is introduced and ejected while rotating it, wherein a nozzle base is attached to a support base, A rotating body is attached to the nozzle base so as to protrude below the support base, and is rotatable by a rotary drive source, and has a jet fluid passage from the nozzle base to the rotating body through the inside of the nozzle base. A plurality of nozzle arms are removably mounted radially on the outer peripheral side surface of the rotating body, and a passage for ejected fluid is provided in these nozzle arms to communicate with the ejected fluid passage in the rotating body. Each was equipped with a nozzle tip. In the above-described configuration, the nozzle arm has a predetermined dimension from a mounting position on the outer peripheral side surface of the rotating body,
A configuration having a horizontal portion that determines the injection range can be adopted. Further, the nozzle tip mounting portion may be configured such that the ejection direction of the ejected fluid is inclined at a predetermined angle with respect to the rotation axis direction of the rotating body toward the rotation center of the rotating body from the front end side of the horizontal portion of the nozzle arm. Further, the nozzle tip mounting point from the horizontal part tip side of the nozzle arm,
The rotating body can be configured to be inclined by a predetermined angle in the positive rotation direction and the negative rotation direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a rotary nozzle device according to the present invention will be described with reference to the accompanying drawings showing an embodiment. FIG. 1 shows a rotary nozzle device 1. This rotary nozzle device 1 is configured such that a cylindrical rotary body 2 is rotatably mounted on a nozzle base (not shown) mounted on a suitable support base (not shown), and a nozzle base is provided. The ejection fluid passage 3 is formed so as to extend from the inlet provided on the top side of the nozzle to the cylindrical rotating body through the inside of the nozzle base.
In addition, appropriate driving means (for example, a motor and a transmission mechanism) for applying a rotational force to the cylindrical rotating body 2 are provided on the support base.
Is provided. The nozzle arms 4a, 4b, 4c, 4
d, 4e, 4f, 4g, and 4h are detachably attached by nuts N. These nozzle arms 4a-4
A passage 5 for ejected fluid is formed in h, and communicates with the ejected fluid passage 3 in the cylindrical rotating body 2 (see FIG. 2). The nozzle arms 4a to 4h are in a horizontal state for a predetermined distance so as to determine an injection range from a mounting point on the outer peripheral side surface of the cylindrical rotating body 2, and a front end side is at a predetermined angle (60 degrees) with respect to the horizontal portion. It is directed to the rotation axis side of the cylindrical rotating body 2. Further, the nozzle arm 4a and the nozzle arm 4b, the nozzle arm 4c and the nozzle arm 4d,...
.. Are inclined at a predetermined angle (approximately 30 degrees) with respect to the vertical direction such that the two tips are close to each other. And at the tip of these nozzle arms 4a to 4h,
The nozzle tips 6a, 6b, 6c, 6d, 6e, respectively
6f, 6g and 6h are mounted. The standard size and shape of the nozzle arms 4a to 4h and the nozzle tips 6a to 6h attached to the cylindrical rotary member 2 can be appropriately selected and attached depending on the ejection target.

In the rotary nozzle device 1 as described above,
Injection fluid is introduced from the top side of the nozzle base, reaches the ejection fluid passage 3 of the cylindrical rotating body 2 through the nozzle base, and is ejected to the nozzle tips 6a to 6h through the passage 5 of the nozzle arms 4a to 4h. When the driving means in the support base is activated to rotate the cylindrical rotator 2 in the state where the fluid is supplied, the ejected fluid hits the ejection target in an arc (see FIG. 3). Here, the nozzle arms 4a to 4h
Since the tip side is directed to the rotation axis side of the cylindrical rotating body 2 by about 60 degrees with respect to the horizontal portion, the nozzle arc
The ejected fluid can be applied at a high angle (close to a right angle) to the end of the ejection range determined by the horizontal portions of the memories 4a to 4h. Further, since the tip side of the nozzle arms 4a to 4h is directed to the rotation axis side of the cylindrical rotary body 2 substantially 60 degrees with respect to the horizontal portion, the jet fluid can be directed to the center side of the jet range. And unevenness can be further reduced. Further, the tip ends of the nozzle arms 4a to 4h are substantially three-way with respect to the vertical direction so that the tips are close to each other two by two.
Since it is inclined at 0 degrees (see FIGS. 1 and 4), even if there are irregularities on the surface of the object to be ejected, the ejected flow hits the surface of the object to be ejected at a large angle (close to a right angle). A great injection effect can be expected (see FIG. 5).

[0007] The rotary nozzle device 1 according to the present invention can provide the above effects, and can be expected to be applied to various fields. For example, when the rotary nozzle device 1 is applied to an object having a large area, the injection range is clearly determined, so that even when the rotary nozzle device 1 is moved while performing the injection, the injection effect can be easily and uniformly provided. Can be. Further, since only the rotating mechanism of the cylindrical rotating body 2 is sufficient, the weight can be easily reduced, and it is also effective as a manual washing device (such as a car washing means of a vehicle) or a painting device that the operator himself moves. .

[0008]

As described above, according to the present invention, (1) the injection angle is high, the injection range with rotation is clarified, and the injection direction is inclined toward the center of the rotating body. , Can provide an even spray effect. (2) Since the structure is simple, it is easy to reduce the weight, and the invention can be applied to a manual device that the operator himself moves.
