DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sprayer used for spraying agriculture, forestry and other chemicals and other liquids, and more particularly to a sprayer nozzle which enables efficient spraying.

[0002]

2. Description of the Related Art As shown in FIG. 7, a nozzle of a conventional sprayer is provided with a spray plate provided in an outermost layer for discharging a chemical solution or the like.
The one provided with a core provided in the lower layer is often used, the injection plate is usually provided with a single hole provided near the central axis, and the core is usually provided with a plurality of holes. The liquid that has passed through the core forms a turbulent flow in the space between the core and the spray plate, and is discharged as a mist from the holes of the spray plate.

[0003]

In such a conventional nozzle, the mist-like liquid discharged from the nozzle plate is discharged in a conical shape, but the central portion of the conical shape is not filled with mist. A part is formed, and the chemical solution is not sprayed in the blank part, causing problems such as not attaching to crops, etc., and the tendency is remarkable in the case of a device that sprays a chemical solution at high pressure using power. Met.

The present invention compensates for the drawbacks of the conventional spraying apparatus, eliminates the blank portion of the chemical solution at the time of spraying, and evenly sprays the chemical solution or the like in any case, thereby enabling efficient spraying. A nozzle is provided.

[0005]

According to the present invention, there is provided a sprayer nozzle having a spray plate and a core, wherein the central axis of the spray plate is defined by the claims. A spray nozzle comprising a plurality of holes obliquely inclined with respect to a nozzle, and a sprayer nozzle having a spray plate and a core, wherein the spray nozzle has a hole parallel to a central axis of the spray plate. A sprayer nozzle, characterized by having a spray port integrally formed with a plurality of oblique holes in the central axis of the plate,
A sprayer nozzle having a spray plate and a core, the spray plate having a plurality of holes oblique to the center axis, and a core having a plurality of holes oblique to the center axis. Including sprayer nozzles, etc.

BEST MODE FOR CARRYING OUT THE INVENTION

[0007]

FIGS. 1 and 2 show a first embodiment of the present invention. FIG. 1 is a perspective view showing the structure of a spray plate and a core according to the present invention, and FIG. 1 is a jet plate, 2 is a hole provided in the jet plate, 3 is a core, 4
Is a hole provided in the core, 5 is an outer cylinder, 6 is a pipe, and 7 is a void.

In this embodiment, three holes 2 are provided obliquely around the central axis of the injection plate 1, and the core 3 is provided with holes 4 parallel to the central axis. The number of oblique holes 2 is 3
The number is not limited to two, and may be any number of two or more. The chemical solution pumped in the direction of the arrow by the pipe 6 passes through the hole 4 of the core 3, becomes a turbulent flow in the gap 7, and is sprayed outside from the hole 2 of the injection plate 1. At this time, the chemicals ejected from the holes 2 are each discharged in a conical shape, but each is ejected at an angle around the axis, so that the ejected liquids are sprayed so as to interfere with each other and draw a spiral. You. Therefore, even in the central part of the ejected chemical solution, the chemical solution spreads and there is no blank portion, so that it is possible to spray the chemical solution uniformly.

[0009]

Embodiment 2 FIG. 3 is a view showing an example of a spray plate used in another embodiment of the present invention. Reference numeral 11 denotes a spray plate, and a hole 12 is formed in the center in the axial direction. A hole 13 oblique to the central axis is provided around the hole 12 so as to extend along the hole 12.

Also in this example, when used in combination with the core shown in FIG. 2, each of the chemicals ejected from the hole 13 is discharged at an angle around the axis. The liquid is sprayed so as to interfere with each other and draw a spiral. Therefore, even in the central part of the ejected chemical solution, the chemical solution spreads and there is no blank portion, so that it is possible to spray the chemical solution uniformly.

[0011]

Embodiment 3 FIG. 4 is a view showing an example of a spray plate used in another embodiment of the present invention. Reference numeral 21 denotes a spray plate, and a hole 23 similar to that shown in FIG.
A hole 22 oblique to the center axis is provided along the hole 23. Also in this example, when used in combination with the core as shown in FIG. 2, in addition to the swirling flow ejected from the hole 23, the chemical solution is ejected from the hole 22 around each axis at an angle. Are intricately interfered with each other and are sprayed. Therefore, as described above, the drug solution spreads everywhere and there is no blank portion,
It is possible to spray a uniform chemical solution.

[0012]

[Embodiment 4] FIG. 5 shows an example of a spray plate used in another embodiment of the present invention, wherein 31 is a spray plate and 32 is a hole provided in the spray plate. In this embodiment, the point that three holes 32 are provided obliquely around the central axis of the injection plate 31 is similar to the example of FIG. 1, but each of the holes 32 is tapered, The size of the spray particles is adjusted. This example also has the same effect as described above.

[0013]

Embodiment 5 FIG. 6 is a perspective view showing the construction of a jet plate and a core showing still another embodiment. 41 is a nozzle plate, 42 is a hole provided in the nozzle plate, 43 is a core, 44 is a hole provided in the center of the core, and 45 is a hole provided on the outer periphery thereof.

In this embodiment, the structure of the injection plate 41 is the same as that of FIG. 3, but the tip of the hole 42 is tapered. The core 43 in this example has the same configuration as the injection plate shown in FIG. 4, and this injection plate and the core are combined in the same manner as shown in FIG. doing.

In this configuration, the chemical liquid is turned into a turbulent flow by the core and is guided to the jet plate, so that the atomizing effect is high,
Since the chemical liquid becomes finer mist-like particles, and the chemical liquid itself ejected from the spray plate is given a spiral motion and sprayed, it is possible to spray the chemical liquid more uniformly.

[0016]

As described above, according to the present invention,
In any spraying device, a nozzle that can evenly and uniformly spray a liquid such as a liquid medicine can be obtained.
