Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a nozzle device for a power mist machine used to spray a small amount of highly concentrated agricultural chemicals.

[Conventional technology]

The conventional nozzle device of this type of power mist machine is the fourth one.
As shown in FIG. In the figure, 1 is a blow pipe of a power misting machine, 2 is a cylindrical nozzle body fixed to the tip of the blow pipe 1, and 3 is a collision plate installed by a bracket 4 on the outlet side of the cylinder of the nozzle body 2, not shown. is starting to rotate. Reference numeral 5 designates a chemical liquid nozzle installed on the cylinder inlet side of the nozzle main body 2 by a bracket 6, which is equipped with a spray amount adjusting orifice 5a and is pre-positioned so as to be able to eject the chemical liquid approximately at the center of the collision plate 3. Reference numeral 7 denotes a liquid supply pipe for supplying the chemical liquid to the chemical liquid nozzle 5.

In such a nozzle device, the chemical liquid is ejected from the chemical liquid nozzle 5 while the air is blown from the air pipe 1. The liquid ejected from the chemical liquid nozzle 5 hits approximately the center of the collision plate 3 as shown by the arrow 8. After being diffused around the outer periphery of the collision plate 3 as shown by arrow 9, it is dispersed along with air from the outer periphery of the collision plate 3 as shown by arrow 10.

In addition, when spraying a small amount of high-concentration agricultural chemicals, it is usually difficult to distinguish with the naked eye the situation shown by the arrow 10, in which the chemical solution is sprayed along with air from around the collision plate 3.

[Problem that the invention attempts to solve]

In the nozzle device of the conventional power misting machine as described above, the liquid ejected from the chemical nozzle 5 indicated by the arrow 8, which can be seen with the naked eye, is inside the nozzle main body 2 and cannot be seen, so there is no dust or the like in the chemical nozzle 5. There was a problem in that the operator opened the hole (not shown) to the chemical solution nozzle 5 and performed the work without realizing that the chemical solution would not spray out due to the blockage, and the purpose of pest control could not be achieved.

This invention was made to solve this problem, and by arranging the liquid ejected from the chemical liquid nozzle so that it can be seen, highly reliable pest control can be performed. The purpose is to obtain a nozzle device for a power mist machine.

[Means for solving the problem] The nozzle device of the power mist machine according to this invention includes a cylindrical nozzle body fixed to the tip of the blow pipe of the power mist machine, and a blower installed inside the cylinder of the nozzle body to blow air. a rotor that is rotated by a rotor and has a concave spherical surface facing outward near the outlet of the nozzle body; It is equipped with a chemical liquid nozzle that spouts a chemical liquid almost at the center.

[Effect]

In this device, the chemical liquid ejected from the chemical liquid nozzle hits approximately the center of the concave spherical surface of the rotor, and then is diffused into a thin film along the concave spherical surface by the centrifugal force of the rotor, and then passes through the outside of the rotor. Since the air is turned into fine particles and dispersed from the outer periphery of the concave spherical surface, the chemical liquid ejected from the chemical liquid nozzle can be seen.

[Example of idea]

Figures 1 to 3 show an embodiment of this invention, and 11 is a rotor installed by a bracket 12 in the cylinder of the nozzle body 2, and is directed outward near the outlet of the nozzle body 2. It is composed of a bowl portion 11a having a concave spherical surface 11A, a bolt 11b whose head is embedded in the bowl portion 11a, and a propeller portion 11c screwed onto the tip of the bolt 11b. 13 is a bearing fitted into the bracket 12, and the bolt 11
b is rotatably supported. Reference numeral 14 denotes a chemical liquid nozzle installed by a liquid sending pipe 15 on the outside of the nozzle main body 2 away from the concave spherical surface 11A, and is arranged on the central axis of the rotor 11 so that the chemical liquid can be ejected approximately at the center of the concave spherical surface 11A. Along with the spray amount adjustment orifice 14
It is equipped with a. 16 connects the liquid feeding pipe 15 to the nozzle main body 2
This is a mounting bracket for attaching to. Note that the same or equivalent parts as in the conventional device described above are given the same reference numerals and explanations are omitted.

Next, the operation will be explained. When air is blown through the air pipe 1, the propeller portion 11c rotates at high speed due to this high-speed wind, and the bowl portion 11a rotates at high speed. When the chemical liquid is ejected from the chemical liquid nozzle 14, the ejected liquid hits approximately the center of the concave spherical surface 11A, and then, as shown by the arrow 17, the centrifugal force of the rotor 11 causes the ejected liquid to hit the concave spherical surface 11A.
The particles are diffused into a thin film along the outer surface of the bowl portion 11a, and are turned into fine particles by the high-speed wind passing outside the bowl portion 11a, and are dispersed from the outer periphery of the concave spherical surface 11A as shown by the arrow 18.

When the liquid ejected from the thin liquid nozzle 14 is thus received by the rotating concave spherical surface 11A, the centrifugal force of the rotor 11 can be utilized, so that the chemical liquid can be finely divided and sprayed.

Furthermore, since the situation in which the chemical liquid is ejected from the thin liquid nozzle 14 can be seen, it is immediately possible to detect when the chemical liquid nozzle 14 is clogged with dust or the like and the chemical liquid is not ejected.

[Effect of idea]

As explained above, this device is arranged so that the liquid ejected from the chemical nozzle can be seen, so it has the effect of ensuring reliable pest control.
