Abstract

PURPOSE:To improve the spraying efficiency of chemical liquid significantly by installing a bifurcated atomization nozzle for spraying chemical liquid, which is positioned obliquely downward from an atomization orifice, on a chemical liquid supply pipe and setting the atomization orifice so that the mist of the chemical liquid is ejected forward and backward in the movement direction of the chemical liquid supply pipe. CONSTITUTION:A chemical liquid atomization device 1 is positioned above a plant 9, and the chemical liquid is sprayed from the atomization orifice 7 of an atomization nozzle 4 in a bifurcated state, that is, C obliquely downward in the forward direction and D obliquely downward in the backward direction. During the above action, a chemical liquid supply pipe 3 is horizontally moved above fruits or trees from a position E to a position E. The chemical liquid sprayed from the atomization orifice to an obliquely downward point C in the forward direction falls over the right half section R of the plant from the bottom to the top sequentially. Next, if the atomization nozzle 4 passes right above the plant 9, the chemical liquid sprayed from the atomization orifice 7 to an obliquely backward point D in the backward direction falls over the left half section L of the plant 9 from the top to the bottom following the movement of the chemical liquid supply pipe 3. Thus the chemical liquid is uniformly sprayed over the plant 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a chemical spraying device for spraying chemicals such as water, liquid fertilizer, insecticides, and fungicides onto fruits, planted trees, and the like.

(Prior Art) In this type of chemical liquid spraying device, for example, a majority-type chemical liquid spraying device, a chemical liquid tank, a drive device that sucks out and pumps the chemical liquid stored in the chemical liquid tank, and a chemical liquid supplied from the drive device are required. It consists of a chemical liquid supply pipe that is manually operated to spray the chemical liquid to a place, and a spray nozzle formed at the tip of the chemical liquid supply pipe. It is formed.

(Problems to be Solved by the Invention) When spraying chemicals such as water, liquid fertilizer, insecticides, and fungicides to plants such as fruits and planted trees using the conventional chemical spraying device, the chemical solution is sprayed from the spray nozzle while spraying the plants. If the chemical solution is simply passed above, the chemical solution will fall only on the upper part of the plant, and it will not be possible to spray it evenly.

In particular, when spraying insecticides on fruit, it is necessary to spray them in the warehouse.

In such cases, it is necessary to move the chemical solution supply pipe while supporting it with your hand, and rotate the drug solution supply pipe so that the direction of the chemical solution sprayed from the spray nozzle follows the outer shape of the fruit.
There was a problem in that the spraying work required time and effort, and the efficiency of the spraying work was extremely low.

Therefore, the present invention was proposed in view of the above problems.
The purpose of the present invention is to provide a chemical liquid spraying device that can uniformly spray a chemical liquid by just passing over fruits, planted trees, etc. with the simple operation of a calendar wheel.

(Means for Solving the Problems) In order to achieve the above object, the chemical liquid spraying device according to the present invention first injects a chemical liquid into a chemical liquid supply pipe that is manually or automatically moved in a bifurcated manner diagonally downward from a spray port. A spray nozzle for spraying is provided, and the spray port is set so that the spray direction of the jJt71 nozzle sprays forward and backward with respect to the moving direction of the chemical solution supply pipe. It is characterized in that the shape is formed into a long hole or an ellipse that is perpendicular to the moving direction of the chemical liquid supply pipe.

(Function) First, while spraying the chemical liquid in a bifurcated form from the spray port of the spray nozzle, the chemical liquid supply pipe is moved, for example, from right to left, above the fruits, planted trees, etc. to which the chemical liquid is to be sprayed.

Then, the right half of the fruit, planted tree, etc. is successively sprayed from the bottom to the top with the chemical solution that is sprayed diagonally downward to the left from the spray nozzle.

Next, when the spray nozzle passes directly above the plant, the chemical solution sprayed diagonally downward to the right from the spray nozzle is sprayed from the top to the bottom of the left half of the plant, and the fruit and planted trees are evenly sprayed with the chemical solution. is applied.

Further, if the shape of the spray port is formed into a long hole or an elliptical diameter perpendicular to the moving direction of the chemical supply pipe, the spray range will be widened.

(Example) Hereinafter, an example of the chemical liquid spraying device according to the present invention will be described based on the drawings.

FIG. 1 shows a perspective view of a chemical liquid spraying device, and reference numeral 1 in the figure indicates the chemical liquid spraying device as a whole.

This chemical liquid spraying device 1 includes a cylindrical chemical liquid supply pipe 3 in which a chemical liquid passage 2 is formed, and a spray nozzle 4 attached to the tip of the chemical liquid supply pipe 3.

The chemical solution supply pipe 3 is manually operated from side to side over plants such as fruits and planted trees, and at the base end of the chemical solution supply pipe 3, a chemical solution is stored in a chemical tank (not shown), which is sucked out by a pressure pump. A medical solution port 5 to which a medical solution is pumped and supplied via a supply hose (both not shown) is opened.

The spray nozzle 4 is removably attached to the tip of the tapered cylindrical drug supply pipe 3 with a fixing nut 6. The lower half of the spray nozzle 4 is formed into a bifurcated shape, and each tip of the bifurcated tip A spray lower having a small-diameter through hole is attached to the center of a thin steel plate by a napht 8.

The spray lower at the tip of the bifurcated injection nozzle 4 is moved in the moving direction of the chemical solution supply pipe 3 (arrows A-B in the figure), in which the chemical solution to be sprayed is manually moved over plants such as fruits and planted trees.
), and the shape of the spray lower is bifurcated with the front facing diagonally downward (C) and the rear diagonally downward (D), and the shape of the spray lower is relative to the moving direction (A - B) of the chemical solution supply pipe 3. The holes are formed to have perpendicular long holes or elliptical diameters so that the shape of the spray spreads widely in a fan shape.

The operation of the chemical liquid spraying device 1 configured as described above will be explained below based on FIG. 2.

First, the chemical liquid spraying device 1 is placed above the plants 9, and the chemical liquid supplied from the pressure pump is sprayed from the spray lower of the spray nozzle 4 into two directions: forward diagonally downward direction (C) and rearward diagonally downward direction CD). While spraying the liquid in a shape, the chemical solution supply pipe 3 is moved from right to left above the fruit, planted tree, etc. to be sprayed from the position (E) shown in the solid line to the position (F) shown in the imaginary line.

Then, the right half (R) of the plant is sequentially sprayed from the bottom to the top with the chemical solution sprayed forward and diagonally downward (C) from the spray nozzle.

Next, when the spray nozzle 4 passes directly above the plant 9, the chemical liquid sprayed backward and diagonally downward (D) from the spray lower is applied to the left half (L) of the plant 9 as the chemical liquid supply pipe 3 moves. The chemical solution is sprayed from the top to the bottom, and the plants 9 are uniformly sprayed with the chemical solution.

Here, if the shape of the spray lower is formed into a long hole or an elliptical diameter perpendicular to the moving direction (A-B) of the chemical solution supply pipe 3 as in this embodiment, the spray range can be widened. .

In the above embodiment, the chemical solution supply pipe 3 is moved manually, but in a greenhouse, for example, rails are formed on both side walls, and the chemical solution supply pipe 3 is moved along the rails by a driving means such as a motor. It goes without saying that the chemical solution supply pipe 3 may be provided with a plurality of spray nozzles, as well as being able to be moved automatically.

Further, in the above embodiment, the spray nozzle 4 is removably attached to the chemical solution supply pipe 3 with the fixing nut 6, but it may be formed integrally with the side wall of the chemical solution supply pipe 3, or Of course, the spray nozzle 4 may be formed by directly drilling a through hole in the portion.

(Effect of the invention) As explained above, according to the chemical spraying device of the present invention,
By simply passing the chemical solution supply pipe over plants such as fruits and planted trees, the chemical solution can be uniformly spread over substantially the entire circumference of the plant.

This has the advantage that the efficiency of spraying the chemical solution can be greatly improved.

In addition, forming the spray nozzle into a long hole or an elliptical diameter perpendicular to the moving direction of the chemical supply pipe has the advantage that the spray range can be widened and the work efficiency of chemical spraying can be further improved. .
