Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a multi-head sprayer head that can intensively spray chemicals and the like on plants such as seedlings.

[Conventional technology]

BACKGROUND OF THE INVENTION Conventionally, sprayers have been commercially available that have a circular tube end and a head to which a plurality of nozzles are attached. Further, there are commercially available sprayers, such as those described in Japanese Utility Model Application Publication No. 60-79557, which have a head having a bifurcated end with a nozzle attached to each end.

These conventional sprayers having a plurality of nozzles can spray chemicals and the like over a wider area than sprayers having only one nozzle.

[Problem that the invention attempts to solve]

However, in the conventional sprayers mentioned above, each nozzle is installed in the same direction in the case of a circular head, and both nozzles are installed facing each other in the case of a bifurcated head. To spray pesticides for pest control, for example, spray from one side along a row where plants are planted while carefully changing the position and orientation of the sprayer head relative to the plants, and then spray along the same row from the opposite side. Similar spraying operations had to be repeated. Therefore, there has been a long-awaited development of a sprayer that can easily perform these troublesome spraying operations.

An object of the present invention is to provide a sprayer head that can spray chemicals and the like to plants such as seedlings from all sides at the same time.

[Means for solving problems]

In the sprayer head of the present invention, the nozzle is attached to the end of the main pipe facing downward, and four branch pipes are attached to the same end, curved into a hook shape so that the tip of each branch pipe faces inward and diagonally upward. It is characterized by being vertically installed and having nozzles attached to the same tip.

In the sprayer head of the present invention, the material of the branch pipe is not particularly limited, but the material of the branch pipe may be changed in terms of corrosion resistance or the shape of the branch pipe to change the arrangement and direction of the diagonally upward nozzle within an appropriate range. It is preferable to manufacture it with copper tubes because it can be used for various purposes. of course,
Metal pipes and synthetic resin pipes other than copper pipes can also be used.

The reason why the number of branch pipes and diagonally upward nozzles is set to four is because plants such as seedlings are pinched from both the front side and the opposite side along the linearly planted ridges, and the chemicals are simultaneously applied to the plants from all four directions above and below. This is to make it possible to disperse etc.

The sprayer head of the present invention can be prepared in several different sizes depending on the size of the plants to be sprayed with chemicals.

[Effect]

In the sprayer head of the present invention, the drug is ejected downward from the downward nozzle at the end of the main pipe, the drug is ejected diagonally upward from the diagonally upward nozzle at the tip of the branch pipe, and the drug ejected diagonally upward is ejected upward. It collides with the jet stream from the downward nozzle and flows downward while spreading in all directions. As a result, the medicine is sprayed from all directions above and below the object to be sprayed.

〔Example〕

FIG. 1 is a perspective view of a sprayer head according to an embodiment of the present invention. FIG. 2 also shows a bottom view. FIG. 3 similarly shows its usage in a perspective view.

In the sprayer head of this embodiment, the nozzle 3 is attached downward to the end 2 of the main pipe 1, and the nozzle 3 is attached downward to the end 2 of the main pipe 1.
The branch pipes 4 are bent in a hook shape so that the tip end 5 of each branch pipe 4 faces inward and diagonally upward, and a nozzle 6 is attached to each of the branch pipes 4.

The end 2 of the main pipe 1 is attached to the tip of the main pipe 1 via an L-shaped short pipe, and the tip 5 of the copper pipe is attached to this end 2.
Four hook-shaped branch pipes 4 are vertically disposed so that the pipes face inward and diagonally upward. Nozzles 6 are attached to the tip portions 5 of these branch pipes 4, respectively.

As the nozzles 3 and 6, known nozzles can be used as they are.

Since the sprayer head of this embodiment has the above-described structure, as is clear from the figure, the medicine is sprayed downward from the nozzle 3 at the main pipe end 2, and from the nozzle 6 at the branch pipe tip 5. From below, medicine is ejected inward and diagonally upward. moreover,
The medicine ejected obliquely upward collides with the ejected flow from the nozzle 3 above and flows downward while spreading in all directions. As a result, the medicine is sprayed onto the object to be sprayed simultaneously from all four directions above and below.

The method of using the sprayer head of this embodiment will be explained with reference to FIG. 3. For example, the sprayer head is held out from one side along a ridge in which plants 7 such as seedlings are continuously planted. When the chemicals are sprayed so that the area is surrounded by the nozzles 3 and 6, the spray liquid 8 is sprayed from the top to the bottom from the nozzle 3, and the spray liquid 8 is sprayed from the nozzle 3 to the bottom.
From there, the spray liquid 8 is sprayed from all sides to the plants 7 from below to diagonally upward, and the spray liquid 8 jetted above the plants 7 from the nozzle 6 collides with the spray liquid 8 from the nozzle 3 and flows downward. be sprayed towards.
Thereby, the chemical can be concentrated and evenly applied to the entire surface of the plant 7 by only spraying from one side of the ridge.

[Effect of idea]

According to the sprayer head of the present invention, by ejecting medicine from the downward nozzle at the end of the main pipe and the diagonally upward nozzles at the tips of the four branch pipes, the medicine is simultaneously sprayed from above and below on the object to be sprayed. Therefore, there are advantages in that it is possible to spray chemicals in a concentrated manner and to perform the spraying efficiently.
