Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical spraying device for a tea plant, which sprays the chemicals on the tea plant in order to control or control helminths and the like attached to the branches of the tea plant.

[0002]

2. Description of the Related Art In controlling or controlling helminths and the like adhering to the branches of tea plants, simply spraying a drug onto the tea plants from above the tea plants has little effect. Most of the chemicals sprayed on the tea tree from above the tea tree adhere to the tea leaves on the surface of the tea tree, and the drug cannot reach the ostracods present on the branches inside the tea tree. Therefore, when exterminating or controlling helminths and the like attached to the branches and the like of tea plants, a method of inserting a long nozzle in a drug spraying device into the tea plants and spraying the drug is generally adopted.

[0003]

However, in the method of spraying the drug by inserting a long nozzle into the tea plant in the drug spraying device, it is not possible to spray the drug evenly throughout the tea plant, but There is a problem that the spraying work is inefficient and it takes a long time to spray the medicine. Therefore, the present invention has been made in order to provide a novel spraying device capable of spraying a drug evenly and efficiently in tea plants.

[0004]

In order to solve the above-mentioned problems, the present invention is designed so that a large number of nozzles are projected on the lower surface of a substantially arcuate substrate having a grip portion and a drug is supplied to each nozzle. The present invention provides a device for spraying a drug on tea plants (claim 1).

Further, according to the present invention, a pair of substantially arcuate substrates are connected to each other, and a grip portion is provided on each of the substrates, and a large number of nozzles are provided on the lower surface of each substantially arcuate substrate so that each nozzle has a medicine. The present invention provides a spraying device for chemicals to tea plants, which is configured to supply (Claim 2).

Immediately before each nozzle on the lower surface of the substantially arcuate substrate, it is desirable to provide a guide means for smoothing the passage of each nozzle in the tea plant (claim 3).

[0007]

[Action]

[Spraying device according to claim 1] When a drug is sprayed into a tea plant using the spraying device according to claim 1, as shown in Fig. 6, a sprinkling device with a substantially arc-shaped substrate applied to the upper surface of the tea plant. The medicine may be sprayed from each nozzle while moving along the tea plant.
If the substantially arcuate substrate is applied to the upper surface of the tea plant, the many nozzles protruding from the lower surface of the substantially arcuate substrate will be immersed in the tea plant respectively.In this state, while moving the spraying device along the tea plant, the chemicals are ejected from each nozzle. If sprayed, the chemical will be evenly and continuously sprayed inside the tea plant. Therefore, ostracods and the like attached to the branches and the like inside the tea plant are completely exterminated or controlled. Further, the substantially arcuate substrate serves to reduce the burden on the operator by applying the weight of the spraying device to the tea plant and prevent the chemicals from scattering upward during the spraying. In FIG. 6, the substantially arcuate substrate of the spraying device covers about half of the tea plant, and the spraying work is performed on each half of the tea plant.

[Spraying device of claim 2] The spraying device of claim 2 is provided with a pair of substantially arcuate substrates. As shown in FIG. It is the same as the spraying device of the above-mentioned claim 1 except that the work is applied to the upper surface.

[Spraying device of claim 3] In the spraying device of claim 3, a guide means for smoothing the passage of each nozzle in the tea plant is provided immediately before each nozzle on the lower surface of the substantially arcuate substrate. Therefore, when the spraying device is moved in a predetermined direction along the tea plant, each guide means separates the tea leaves and branches in the tea plant just before each nozzle to secure a passage space for each nozzle. Therefore, each nozzle smoothly moves through the tea plant without being caught by the tea leaves or branches in the tea plant.

[0010]

Embodiments of the present invention will now be described with reference to the accompanying drawings. Reference numeral 1 is a substantially arc-shaped substrate that fits the surface of the tea plant 3. A grip portion 7 is attached to the substantially arc-shaped substrate 1 via a support rod 5. A large number of nozzles 9 are provided on the lower surface of the substantially arc-shaped substrate 1.
Is provided so as to project the drug to each nozzle 9 through the drug supply pipe 10. Reference numeral 12 is a valve. In addition, it is desirable that the spraying device is configured to hold the grip portion 7 and pull it toward the front side.

In the case shown in FIGS. 3, 4 and 7,
A pair of substantially arc-shaped substrates 11 that fit the surfaces of the two rows of tea trees 3
Are connected to each other. It is desirable that the space between the substantially arc-shaped substrates 11 can be adjusted according to the space between the tea trees 3, 3. That is, as an example, these substantially arc-shaped substrates 1
1 are connected to each other via interlocking connecting rods 13 and 15 having adjustable lengths. 17 is a fixing screw of the connecting rod 13, 19
Is a fixing screw of the connecting rod 15, and 21 is a long hole formed in the connecting rod 15 for adjusting the length. A grip portion 29 is attached to the pair of substantially arcuate substrates 11 via support rods 23, 25, 27. The support rod 23 in FIG. 3 is pivotally attached to the substantially arcuate substrate 11 and the support rod 25. A large number of nozzles 31 are projectingly provided on the lower surface of each substantially arcuate substrate 11, and a drug is supplied to each nozzle 31 via drug supply pipes 33 and 35.
Reference numerals 37 and 39 are valves.

Immediately before each nozzle 9 (31) on the lower surface of the substantially arcuate substrate 1 (11), guide means 41 for smoothing the passage of each nozzle 9 (31) in the tea plant 3 is provided. Is desirable. An example of the guiding means 41 is shown in FIG. 5, but the guiding means 41 may have any shape as long as it can separate tea leaves and branches in the tea plant 3 and secure a passage space for the nozzle 9 (31). Good. Figure 5
The arrow in indicates the traveling direction of the spraying device.

[0013]

As described above, according to the present invention,
In the work of exterminating or controlling helminths and the like adhering to the branches and the like of tea trees, the chemicals can be evenly and efficiently applied to the tea trees in a short time. Further, the weight of the spraying device is applied to the tea plant through the substantially arcuate substrate, so that the burden on the operator is reduced. Further, the substantially arcuate substrate prevents the drug from scattering upward.
