Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a nozzle device installed in the ohmic tube of a speed sprayer used, for example, in orchards.

[Conventional technology]

A conventional nozzle device of this type will be explained with reference to FIGS. 4 and 5. Figure 4 is a half-section side view, Figure 5
The figure is a plan view. In the figure, 1 is an ohmic tube,
2 is a nozzle base disposed on the ohmic tube 1, and 3 is a spout plate disposed in front of the nozzle base 2, which has a cutting 3a for flat spraying.
Reference numeral 4 designates a cap for attaching the spout plate 3 to the spout base 2 via the packing 5, and has an inner circumferential flange 4a that is screwed onto the spout base 2 and engages with the spout plate 3.

In this nozzle device, the direction of flat spraying is determined by the orientation of the cutting 3a. Therefore, by loosening the cap 4 and rotating the spray plate 3 in the direction of the arrow 6, the direction of flat spraying was changed as shown by the imaginary line.

[Problem that the invention attempts to solve]

In the conventional nozzle device as described above, the cap 4
When the spout plate 3 is rotated, the spout plate 3 rotates together with the spout plate 3, so it is difficult to determine the orientation of the spout plate 3, and it is difficult to adjust the orientation of the spout plate.

This invention was made to solve these problems, and the object is to provide a nozzle device in which the direction of the spout plate can be easily determined and the orientation of the spout plate can be changed and adjusted easily and accurately.

[Means for solving problems]

In the nozzle device according to this invention, the nozzle main body is removably fixed to the nozzle base by a nut-shaped cap, and the outer cylinder to which the nozzle plate located in front of the nozzle main body is attached is rotatably fitted to the nozzle main body. The outer circumferential flange of this outer cylinder is engaged with the inner circumferential flange of the cap so that the outer cylinder is rotatably fitted to the nozzle main body, and a ring attached to the outer periphery of the nozzle main body This prevents the outer cylinder from rotating naturally.

[Function] In this invention, the outer cylinder to which the spout plate is attached is rotatably fitted to the spout body by the cap,
This outer cylinder is normally pressed by the ring and does not rotate naturally, so of course the jet plate does not rotate either, but when changing the direction of the jet plate, the outer cylinder rotates by rotating it against the pressing force of the ring. You can change the direction of the spout plate.

[Example of idea]

An example of this invention is shown below in Figures 1 and 2.
The diagram will be explained. FIG. 1 is a half-sectional side view, and FIG. 2 is a plan view, and the same or corresponding parts as those of the conventional device will be described with the same reference numerals. In the figure, 7 is a nozzle main body having an internal passage 7a, 8 is an orifice fitted into the internal passage 7a, 9 is an outer cylinder rotatably fitted to the nozzle main body 7, and 10 is a nozzle base 2.
It is a nut-shaped cap that is screwed onto the nozzle body 7, and has a stepped portion 10a that engages with the outer circumferential flange 7b of the nozzle main body 7, and an inner circumferential flange 10b that engages with the outer circumferential flange 9a of the outer cylinder 9. . Reference numeral 11 denotes an O-ring for preventing liquid leakage attached to the outer peripheral flange 7c of the nozzle main body 7, which presses the outer cylinder 9 from the inner circumferential surface to prevent the outer cylinder 9 from rotating naturally. Reference numeral 12 denotes a gasket fitted between the nozzle base 2 and the nozzle main body 7, and holds the koshiami 13. 14 is an intake port provided in the outer cylinder 9, and 15 is a vent provided in the nozzle main body 7, which allows the internal passage 7a and the intake port 14 to communicate with each other. Reference numeral 16 denotes a knurl formed on the outer peripheral surface of the outer cylinder 9.

In the state shown in FIG.
is engaged with the stepped portion 10a of the cap 10, and the nozzle main body 7 is fixed to the nozzle base 2 by the cap 10, and the outer circumference flange 9a of the outer cylinder 9 is engaged with the inner circumference flange 10b of the cap 10 (as shown in the figure). The outer cylinder 9 is fixed by an O-ring 11, although it can be rotated with respect to the cap 10 (there may be a gap as shown in the figure). Therefore, in this state, the outer cylinder 9 does not rotate naturally, so the direction of the spout plate 3 does not change.

When changing the direction of flat spraying by changing the orientation of the spray plate 3, the outer cylinder 9 may be rotated against the pressing force of the O-ring 11. Even when the outer cylinder 9 is rotated, the outer cylinder 9 only rotates on the nozzle body 7 and has no effect on the nozzle body 7 and the cap 10, and liquid leakage is prevented by the O-ring 11. If the outer cylinder 9 is rotated in the direction of the arrow 6 and left as it is, it will be fixed again by the O-ring 11.

In the above embodiment, the nozzle device has a structure in which air is sucked into the nozzle main body 7 from the intake port 14 through the vent hole 15, but as shown in FIG. Effects can be obtained. The device shown in FIG. 3 can be downsized.

In addition, the effect of this invention becomes even more remarkable in a device equipped with 24 to 28 nozzle devices, such as the ohmic tube 1 of a speed sprayer.

[Effect of idea]

As described above, this invention has the advantage that the direction of the spray plate can be easily determined and the orientation of the spray plate can be changed and adjusted easily and accurately.
