Description

[Detailed Description of the Invention] This invention relates to a spray head for a power sprayer useful for ridge spraying of crops such as soybeans, for example.

That is, the gist of this invention is to form a spherical shell that swells from approximately the center to both sides of the jet head body that is connected to the tip of the jet pipe of a power spreader and can move over the spraying ground. At the same time, a plurality of discharge ports opening radially on both sides and the upper surface of this spherical shell part are formed, and a chemical liquid pipe connected to a chemical liquid supply source is attached to the outer surface of the spherical shell part, and a discharge port of this chemical liquid pipe is formed. A nozzle hole is drilled in each part adjacent to the outlet, and by the negative pressure induction effect of the air ejected from the discharge port, the chemical liquid in the chemical liquid pipe is spread over a wide range of angles towards both sides of the jet head body. An object of the present invention is to provide a spray head for a power sprayer, which is characterized by being able to spray with a large amount of water, thereby improving pest control efficiency and pest control effect.

Examples of this invention will be described below based on the drawings.

Figures 1 to 5 show a first embodiment of the jet head of this invention, and the jet head 1 of this invention, as shown in Figure 5,
A jet head main body 4 is connected to the tip of a jet pipe 3 of a power spreader 2 carried on the back of the worker A, and a chemical liquid pipe 7 is connected to a hose 6 connected to a chemical liquid tank 5 which is a chemical liquid supply source of the power spreader 2. , a sled 8 that is installed on the lower surface of the jet head body 4 and is a moving means that is advantageous for moving the jet head main body 4 over the sprayed ground; and trailing guides 9, 9 installed on both sides of the jet head main body 4. Its main parts are composed of:

The jet head main body 4 is shaped like an oval disk having a spherical shell part 10 that bulges toward both sides at approximately the center thereof, and radially extending spherical shell parts 10 on both sides and the upper surface of the spherical shell part 10. A plurality of discharge ports 11, 11, .
Nozzle holes 13, 13, .

Further, the pioneer guides 9, 9 each have a jet head main body 4.
It is installed in a tapered shape that widens from the tip toward the spherical shell portion 10, and its shape is maintained by a tension coil spring 14.

As shown in FIG.
The air connected to the tip of the jet pipe 3 is connected to the dispensing port 11 of the spherical shell part 10, and air is supplied from the jet pipe 3 while being moved on the sprayed ground.
Due to the negative pressure induction effect when passing through and being ejected to the outside,
The chemical liquid in the chemical liquid pipe 7 can be sprayed from each nozzle hole 13 toward both sides of the jet head 1 at a wide range of spray angles.

At this time, the crops etc. to be sprayed with the chemical are swept aside on both sides of the spray head 1 by the weeding guides 9, 9, so that the chemical solution is effectively sprayed.

6 to 9 show a second embodiment of this invention, in which wheels 8' are used instead of the sled 8 as the moving means.

The rest of the structure is the same as that of the first embodiment, so the same parts are given the same reference numerals and the explanation thereof will be omitted here.

As explained above, according to the spray head of this invention, even in areas where spraying conditions are poor, such as in ridges, it is possible to spray crops, etc. to be sprayed in a wide range of spray angles in the left and right directions while moving the crops, etc. to be sprayed left and right. Since the chemical solution can be sprayed with the sprayer, the pest control efficiency and pest control effect can be improved compared to conventional spraying operations, and its utility value is remarkable.

Claims (1)

[Scope of Claim for Utility Model Registration] 1. A spray head body that is connected to the tip of the spray pipe of a power spreader and can be moved over the sprayed ground by means of a moving means installed on its underside, which bulges out toward both sides at approximately the center of the spray head body. A spherical shell is formed, a plurality of discharge ports are formed radially on both sides and the upper surface of the spherical shell, and a chemical liquid pipe connected to a chemical liquid supply source is attached to the outer surface of the spherical shell. At the same time, a nozzle hole is formed in each of the parts of the chemical liquid pipe adjacent to the discharge port, so that the chemical liquid in the chemical liquid pipe is sprayed by the negative pressure inducing effect of the air passing through the discharge port. The head of a power spreader. 2. The jet head of a power spreader according to claim 1, wherein the moving means is a sled. 3. The jet head of a power spreader according to claim 1, wherein the moving means is a wheel. 4. The jet head for a power spreader according to claim 1, wherein the jet head main body is provided with trailing guides each having a tapered shape that widens from the tip toward the spherical shell portion on both sides of the jet head body.
