DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for spraying chemicals on tea plants, which sprays chemicals on tea plants in order to control or control shell worms or the like adhering to branches and the like of tea plants.

[0002]

2. Description of the Related Art In controlling or controlling shell worms or the like adhering to a branch or the like in a tea tree, it is hardly effective to simply spray a chemical onto the tea tree from above the tea tree. Most of the medicine sprayed on the tea plant from above the tea plant adheres to the tea leaves on the surface of the tea plant, and does not reach the shellworms present on the branches and the like inside the tea plant. Therefore, in order to exterminate or control shell worms or the like adhering to branches or the like in a tea tree, a method is generally employed in which a long nozzle of a chemical spraying device is inserted into the tea tree to spray the chemical.

[0004]

However, the method of spraying a medicine by inserting a long nozzle into a tea tree in a medicine spraying apparatus cannot not only spray the medicine evenly in the tea tree, but also disperse the medicine. There is a problem that the spraying operation is inefficient and it takes a long time to spray the medicine.

(Claim 1).

(2) Connecting a pair of substantially arc-shaped substrates to each other
At the bottom of each substantially arc-shaped substrate.
Has a large number of nozzles protruding from it and supplies the drug to each nozzle
In the device for spraying chemicals to the tea plant,

(Claim 2).

[0010]

[Function] Spraying device according to claim 1 When spraying a medicine into tea plant using the spraying device according to claim 1, as shown in FIG. 6, a substantially arc-shaped substrate is brought into contact with the upper surface of the tea plant. Then, the medicine may be sprayed from each nozzle while moving the spraying device along the tea tree. If the substantially arc-shaped substrate is brought into contact with the upper surface of the tea tree, a number of nozzles protruding from the lower surface of the substantially arc-shaped substrate are respectively immersed in the tea tree. Is sprayed continuously throughout the tea plant.
Therefore, shellworms and the like adhering to the branches and the like inside the tea plant are completely eliminated or controlled. In addition, the substantially arc-shaped substrate plays a role of reducing the burden on the operator by applying the weight of the spraying device to the tea tree and also preventing the medicine from scattering upward during spraying. In FIG. 6, the substantially arc-shaped substrate of the spraying device covers approximately half of the tea plant, and the spraying operation is performed for each half of the tea plant.

Thus, in the spraying device of the first aspect,
Is a tea tree just before each nozzle on the lower surface of the substantially arc-shaped substrate.
For smooth passage of each nozzle inside
Means, so that the spraying device
When moving in the direction, each guide means immediately before each nozzle
The tea leaves and branches in the tea plant with a nozzle.
Security. Therefore, each nozzle is attached to tea leaves and branches in the tea plant.
Proceed smoothly through the tea plant without getting caught.

[Scattering device of claim 2] The spraying device of claim 2 is provided with a pair of substantially arc-shaped substrates, and as shown in FIG. It is the same as the spraying device of claim 1 except that the work is performed by contacting the upper surface.

[0013]

Next, an embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 denotes a substantially arc-shaped substrate that fits on the surface of the tea tree 3. A handle 7 is attached to the substantially arc-shaped substrate 1 via a support rod 5. A number of nozzles 9 are provided on the lower surface of the substantially arc-shaped substrate 1.
And a drug is supplied to each nozzle 9 via a drug supply pipe 10. Reference numeral 12 denotes a valve. In addition, it is desirable that the spraying device be configured to hold the handle 7 and pull it toward the user.

In the cases shown in FIGS. 3, 4 and 7,
A pair of substantially arc-shaped substrates 11 adapted to the surfaces of two rows of tea plants 3
Are interconnected. It is desirable that the interval between these substantially arc-shaped substrates 11 can be adjusted according to the interval between the tea plants 3 and 3. That is, as an example, these substantially arc-shaped substrates 1
1 are connected to each other via nested connecting rods 13 and 15 whose length is adjustable. 17 is a fixing screw of the connecting rod 13;
Is a fixing screw of the connecting rod 15, and 21 is an elongated hole formed on the connecting rod 15 for adjusting the length. A handle 29 is attached to the pair of substantially arc-shaped substrates 11 via support rods 23, 25, 27. The support rod 23 in FIG. 3 is pivotally attached to the substantially arc-shaped substrate 11 and the support rod 25. A large number of nozzles 31 are protruded from the lower surface of each substantially arc-shaped substrate 11, and a medicine is supplied to each nozzle 31 through medicine supply pipes 33 and 35.
Reference numerals 37 and 39 are valves.

A guide means 41 for smoothing the passage of each nozzle 9 (31) in the tea tree 3 is provided immediately before each nozzle 9 (31) on the lower surface of the substantially arc-shaped substrate 1 (11). Is desirable. An example of the guiding means 41 is shown in FIG. 5, but the guiding means 41 may be of any shape as long as it can push through the tea leaves and branches in the tea tree 3 and secure a passage space for the nozzle 9 (31). Good. FIG.
The arrow in indicates the traveling direction of the spraying device.

[0016]

As described above, according to the present invention,
Each nozzle protruding from the lower surface of the substantially arc-shaped substrate sinks into the tea tree
In this state, move the spraying device along the tea plant in this state.
Spray the medicine from each nozzle and the medicine will spread all over the tea plant
It is sprayed continuously without. Therefore, the branches inside the tea plant
Efficient and efficient extermination of shellworms and the like adhering to
Can be controlled. Further, in the spraying device of the present invention,
Immediately before each nozzle on the lower surface of the substantially arc-shaped substrate
Plan for smooth passage of each nozzle in the tree
Because of the internal means, the spraying device must be
When moving in the direction of
The tea leaves and branches in the tea plant are separated in front, and the passage
Secure source. Therefore, each nozzle has tea leaves and branches in the tea plant.
It goes smoothly through the tea tree without getting caught in the.
