[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tea leaf plucking device for plucking tea leaves on the surface of a tea ridge and a method for controlling pests of tea trees by the tea leaf plucking device.

[0002]

2. Description of the Related Art Tea leaves may be picked manually by hand, but at present, most of them are mechanically mowed by an engine-driven tea leaf picking machine. Since pathogenic bacteria easily invade from the tea leaf plucking cut edge of the tea tree, it is necessary to take preventive measures immediately after plucking. An example of the material that supports this is (published by) the Shizuoka Prefectural Tea Chamber (Showa 59).
The "visual pests of tea" show that conidia of the ring spot fungus are germinated at the wound site of the leaves as early as 4 hours after the plucking. For this reason, conventionally, it has been general to spray chemicals on tea trees after tea leaf plucking.

[0003]

However, in a farmer having a relatively large production scale, since the tea manufacturing plant is not in operation immediately after the plucking, the chemical spraying is delayed, which causes a great deal of damage. There was an occasion. In addition, there is a safety and health problem that the worker is easily exposed to the radiation by dynamic spraying, and there is also a demand to reduce the amount of agricultural chemicals used as much as possible.

In order to solve the above problems, the present invention aims to control pests by picking tea leaves and at the same time attaching a chemical to the excision cut end to control pests and to easily perform the control work. To do.

[0005]

For this purpose, the following tea leaf plucking device and a method for controlling pests of tea trees by the tea leaf plucking device have been created. That is, in the invention according to claim 1, the portable frame is provided with a plucking mechanism that plucks tea leaves on the surface of the tea ridge with the movement of the frame, a drive device that drives the plucking mechanism, and the plucking mechanism. It is characterized in that it is provided with a medicine adhering means for adhering a medicine to the plucking cut end of the cut tea tree. In the invention according to claim 2, the medicine adhering means is arranged in a substantially arc shape so as to be along the surface of the tea ridge, and is formed so as to be able to come into contact with the plucking cut end of the tea tree containing the medicine, a roller brush, a mat, etc. Is a coating means. Further, in the invention according to claim 3, a plucking mechanism that moves along the tea ridges and plucks the tea leaves and a drug adhering means that attaches a drug to the tea tree are integrally configured, and the plucking mechanism picks the tea leaves. Immediately after that, the medicine adhering means is adapted to adhere the medicine to the plucking cut end of the tea tree.

[0006]

In the invention according to claim 1, the frame is moved to continuously pick the tea leaves on the surface of the tea ridge by the plucking mechanism, and then the drug is attached to the plucking cut end of the tea tree by the drug attaching means. Can be made. Further, in the invention according to claim 2, the agent is applied by bringing a brush, a roller brush, a mat or the like containing the agent into the plucking cut edge of the tea plant. In the invention according to claim 3, the pests can be effectively controlled because the drug is attached to the excision cut edge immediately after the tea leaves are plucked.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. 1 is a front view of the tea leaf plucking device, FIG. 2 is a top view thereof,
FIG. 3 is a sectional view taken along line AA of FIG. In addition, in FIG. 2, the leaf bag 6 is removed. As shown in FIGS. 1 to 3, the tea leaf plucking device 1 attaches a drug to a plucking mechanism 2 capable of plucking a tea leaf t on a surface of a tea ridge T and a plucking cut end of a tea tree cut by the plucking mechanism 2. It is roughly classified into a coating mechanism 10 (also referred to as a coating means) that is a means for adhering a medicine.

First, the plucking mechanism 2 will be described. A thin plate-shaped blade 4 curved in an arc shape corresponding to the tea ridge T is attached to a portable pipe frame 3 having grips 3a, 3b on both left and right sides, and a blade body is formed in an arc shape at a front end portion of the blade 4. A hair clipper type cutter 5 extending to the front is provided, and a leaf bag 6 can be attached to and detached from the rear end portion of the blade 4. Further, a blower 7 is attached to the frame 3, air is ejected from the nozzle 7a of the blower 7 toward a position near the cutter 5, and the air is ejected from the tea leaf plucking device 1
The air that has flowed rearwardly into the leaf collecting bag 6 and inflated the leaf collecting bag 6 is discharged from the mesh portion 6 a of the leaf collecting bag 6. The cutter 5 and the blower 7 are driven by a driving device attached to the frame 3, for example, a driving engine 8.

Next, the coating mechanism 10 will be described. On the lower surface side of the thin plate-like support substrate 11 connected to the rear end of the blade 4 via a connecting tool 4b, the roller brush 1
2, the brush 13, and the pipe 14 are attached. The roller brush 12 has, for example, a hygroscopic material such as felt on a cylindrical surface. In this embodiment, five rollers are arranged in a front row and four rows are arranged in a back row in a zigzag manner, and a portion left unpainted in the front row is a rear row. It is ready to be painted. Five brushes 13 arranged after the roller brush 12 are formed so that the bristle tips extend below the rolling surface of the roller brush 12, and the bristle tips can easily reach the portion recessed from the surface of the tea ridge T. There is.
A pipe 14 for supplying a drug (in the present embodiment, a wettable powder of an appropriate pesticide, etc.) is branched into three pipes, and the front two branch pipes 14a and 14b are shown in FIGS. As described above, the drip brush 15 having relatively short bristles is attached in close proximity to the roller brush 12, so that the drug dripping from the small holes of the branch pipes 14 a and 14 b is supplied to the roller brush 12 through the drip brush 15. Has become. Note that the brush 13 is attached to the branch pipe 14c in the last row so that the medicine ejected from the small hole of the branch pipe 14c is transmitted to the brush 13. In FIG. 4, reference numeral 12a is a mounting bracket for rotatably supporting the roller brush 12, and 13a is a brush 13
14d is a fitting for the pipe 14.

The pipe 14 includes branch pipes 14a to 14c.
The valve 14e and the joint 14f are attached to the connecting portions at both ends of the c.
The hose 16 can be selectively connected to. The hose 16 is connected to a medicine tank 17a of a back sac 17 which is carried by the operator as shown in FIG. In the figure,
17b is a cook. Therefore, the drug tank 17a
Can be placed on either the left or right side of the tea leaf plucking device 1, which is convenient for work.

Further, referring to FIGS. 1 and 2, a thin partition plate 18 is connected to the rear end portion of the support substrate 11 via a connector 18a, and is placed on the support substrate 11 and the partition plate 18. The leaf-collecting bag 6 has an opening whose upper side is engaged with the hook 3c of the frame 3 and whose lower side is engaged with the hook 4a of the blade 4.

Next, the operation of the tea leaf plucking apparatus 1 having the above-mentioned structure will be described. Now, two workers standing on both sides of the tea ridge T support the handles 3a and 3b of the frame 3 and start the drive engine 8, and then move the cutter 5 along the surface of the tea ridge T to move the tea leaves. Pick and pick. Then, the picked tea leaves t are carried into the leaf bag 6 by the air blown from the nozzle 7a. The cock 17b and the valve 14e are opened in advance so that the medicine in the medicine tank 17a flows from the hose 16 to the pipe 14 of the coating mechanism 10. The chemical is dripped from the small holes of the branch pipes 14a to 14c to wet the roller brush 12 and the brush 13. Then, when the cutter 5 cuts the tea plant, the roller brush 12 comes into contact with the plucking cut edge immediately after that to apply the medicine. Further, since the drug is also instilled into the brush 13, the brush 13 can apply the drug to the plucking cut edge of the tea tree at a slightly recessed position that the roller brush 12 did not reach. Therefore, there is almost no unpainted portion left. The drip amount of the medicine at this time is determined by the branch pipes 14a to 14a.
It can be set appropriately by adjusting the diameter of the small hole of 4c and the opening of the cock 17b or the valve 14e. It can be reduced to a fraction. Therefore, it becomes possible to minimize environmental pollution,
The worker does not take or inhale the medicine.

Further, when the operator moves the tea leaf plucking device 1 while supporting it, the roller brush 12 can abut a certain amount of load by abutting against the tea plant, so that the posture of the tea leaf plucking device 1 can be stably maintained. It's easy. Note that the normal tea ridge T has a semicircular semi-cylindrical shape, and the cutter 5 is applied to each half surface (approximately 1/4 yen) of the tea ridge T to allow the worker to make one reciprocation. Since the picking and control of the whole tea ridge T is completed at the same time, the work efficiency is extremely good.
After that, when the tea bag 6 is filled with the tea leaves t, the tea bag 6 is removed from the tea leaf plucking device 1.

In the tea leaf plucking apparatus 1 of this embodiment, the support substrate 11 covers the coating mechanism 10 and the support substrate 1
The leaf-collecting bag 6 is placed on the partition plate 1 and the partition plate 18, and it is difficult for the medicine to adhere to the leaf-collecting bag 6. Therefore, it is possible to prevent the tea leaves t in the leaf-collecting bag 6 from being accidentally contaminated with the medicine. In addition, although the coating mechanism 10 is attached to the support substrate 11 in this embodiment, the coating mechanism 10
By providing the blade 4 of the plucking mechanism 2 with the plucking mechanism 2, the tea leaf plucking apparatus 1 can be downsized. Further, although the roller brush 12 is used in the coating mechanism 10, it is also possible to use, for example, a felt-made drug coating mat 22 as shown in FIG. 5 in place of the roller brush 12.
In this case, the tea leaf plucking device 1 can be manufactured at a lower cost because the structure is relatively simple. Also,
Instead of the coating mechanism 10 described in the present embodiment, a small sprayer may be attached to the support substrate 11 or the blade 4 to form the medicine adhering means. In this case, it is preferable to surround the support substrate 11 with a skirt such as a vinyl sheet to prevent the chemicals from scattering. Further, although the tea leaf plucking device 1 is configured as a hand-held type, it is conceivable to provide a self-propelled tea leaf plucking machine with the drug adhering means referred to in the present invention. .

[0015]

As described above in detail, according to the present invention, pests can be extremely effectively controlled because the tea leaves can be plucked and the drug can be attached to the plucking cut mouth at the same time. In addition, there is a remarkable effect that work efficiency can be improved. Further, the invention according to claim 2 is a brush, roller brush,
Since it is applied with a mat, etc., the chemical does not scatter unlike the dynamic spraying, so the worker does not bathe or inhale the chemical, ensuring work safety and reducing the amount of chemicals used There is an effect that can be.
