Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a method and apparatus for injecting a liquid substance into living trees, and particularly relates to a method for injecting a liquid substance into live trees and an apparatus therefor, and in particular, the present invention relates to a method for injecting a liquid substance into live trees, and an apparatus therefor. The present invention relates to a method and apparatus for injecting a liquid substance into a live tree, which is preferably used when administering a liquid substance such as an insecticide or a prescribed nutrient.

[Conventional technology]

BACKGROUND ART Injecting liquid substances into living trees has been used relatively often in the past for exterminating pests, supplying nutrients, etc. as described above. Particularly in recent years, pine tree abandonment has been occurring frequently, and as a measure to prevent this, a method of drilling holes in living pine trees and administering insecticides has been implemented in various places.

[Problem that the invention seeks to solve]

However, in such conventional examples, when administering nutrients or pesticides to living trees, most of them adopt a method of administering the target liquid substance in accordance with the movement of the sap of the living tree. This has caused an inconvenience in that it takes several days or a week or so for the administration of the liquid substance to start and end.

For this reason, for example, administering nutrients to a large number of living trees requires a large number of injection equipment, and on the other hand, to avoid this, it is necessary to spray the nutrients into the soil at the base of the living trees, which has a high absorption rate. The situation was such that they had no choice but to adopt an extremely slow method.

[Purpose of the invention]

The present invention improves the disadvantages of such conventional examples, and (
It is an object of the present invention to provide a method and apparatus for injecting a liquid substance into a living tree, which can quickly and sufficiently administer a necessary liquid substance to a living tree.

[Means for solving problems]

Therefore, in the present invention, a hole with a relatively small diameter is formed in any part of a green tree, and a guide means for liquid injection is provided on the opening side of the hole while leaving an appropriate amount of space inside the hole. A structure is adopted in which a liquid nutrient or other liquid substance is press-fitted while applying a predetermined pressure through a through-hole formed in advance in the central shaft portion of this liquid injection guide means. This aims to achieve the above objective.

[First Embodiment] Hereinafter, a first embodiment of the present invention will be described based on FIGS. 1 to 5.

In FIG. 1, 1 indicates a green tree, and 2 indicates a large part of the green tree 1 that has been processed and formed. Further, 3 indicates a liquid injection guide means, 4 a pressure hose, 5 a pressure pump, and 6 a tank body containing an injection liquid.

As shown in FIGS. 2 and 3, the pre-liquid injection guide means 3 includes a green wood insertion section 11, a stopper section 14, and a check valve gi.
A twisting part 12A for connecting the pressure hose 4 is formed on the outer diameter side of the check valve mechanism 15, and a screw connection part 12A for connecting the pressure hose 4 is formed on the central axis of the injection guide part 11. A through hole 20 is provided.

Of these, the check valve mechanism 15 includes a pressure spring 16, a seal member 17, and a valve member 18. As shown in FIGS. 3 to 4, the valve member 18 has four large cutout portions 18A around the periphery, and a protrusion 18B is provided at the center of the right end in FIG. A spring locking recess 18c and a stopper portion 18D are formed on each side. For this reason, the female connector 12 on the pressure hose 4 side
When the protruding portion 18B is pressed by B (see FIG. 2),
The entire valve member 18 is pressed to the left in FIG. 3, and as a result, a predetermined liquid material force 5 is fed from the pressure hose 4 side. Then, the main part 2 of the living tree 1 is passed through the through hole 20 formed on the central axis of the guide means 3 for liquid injection.
A liquid substance is press-fitted into the living tree, and the pressure allows the liquid substance to penetrate into the living tree very easily.

In this case, the average pressure of the sap of the living tree 1 itself is "0 to 0.3 megapascals" (however, 0.1 megapascals) at the roots.
Megapascals = 1 atm), and the numbers r-0.3 to -1.0 megapascals are known for the kuki part, and -40 megapascals for the leaf parts.

For this reason, when a liquid is injected under atmospheric pressure, for example, at a location other than the roots, the liquid will naturally permeate into the tree without flowing backwards.

On the other hand, when injecting liquid into many living trees, it becomes necessary to forcibly inject the liquid in a short period of time in order to improve efficiency. In such a case, the relationship between the injection rate of the liquid per unit time and the liquid pressure (applied pressure) was experimentally obtained as shown in Figure 5 when the target was a pine tree.

Therefore, when a pressure of, for example, 10 atmospheres or higher was applied to the injection liquid, the result was that the injection speed of the liquid into the green tree suddenly increased.

Here, an increase in the pressure of the liquid to be injected simultaneously causes a situation in which the liquid injection guide means 3 tends to separate from the living tree due to the reaction force. For this reason, in this embodiment, a wood screw mechanism 11A is formed on the outer periphery of the green wood insertion part 11 of the liquid injection guide means 3 as a fixing means, thereby preventing the liquid injection guide means 3 from separating from the green tree. It is prevented.

Further, most of the portion 2 formed on the green tree 1 described above is formed relatively deep because of the pressure injection of the liquid substance, and the diameter thereof varies depending on the thickness of the green tree, but the guide means 3 for liquid injection used is The dimension is set to be somewhat smaller than the root diameter of the wood screw mechanism 11A. Therefore, after screwing the green wood insertion part 11 into the green tree 1, the liquid injection guide means 3 is firmly fixed to the green tree 1 by the screw action of the wood screw mechanism 11A. What about this living tree? fl In this embodiment, the resident guide means 3 is attached and detached using, for example, an adjustable spanner.

21 indicates a rubber backing, and 22 indicates an external force applying section for screwing.

In this embodiment, the pressure pump 6 is capable of applying a pressure of about 30 atmospheres to the liquid substance. Although the pressure pump 6 is of a manual type in this embodiment, it may be of a motor-driven type with an appropriate speed control section.

Therefore, according to this embodiment, a predetermined amount (e.g., 30 cc) of a predetermined liquid substance such as a nutrient is applied to a desired green tree within a very short period of time (e.g., about 10 minutes including the work time before and after). In addition, the effect of the wood screw mechanism 11A can completely eliminate the inconvenience of the liquid injection guide means 3 separating from the green tree 1.

In the first embodiment, the case where the tank body 6 is separate from the pressure pump 5 is illustrated, but the pressure pump 5
The tank body 6 may be detachably housed in the tank body.

(Second Embodiment) Next, a second embodiment will be described based on FIGS. 6 and 7.

This second embodiment is based on the living tree 1 in the first embodiment described above.
When inserting and fixing the guide means 3 for liquid injection, a water-containing member 3 made of sponge, fiber, etc.
A is inserted in a detachable manner, and then the guide means 3 for the guide member 3 is inserted and fixed. The other configurations are the same as those of the first embodiment described above.

Even in this case, in addition to having the same effect as the first embodiment described above, the water-containing member 3A is brought into contact with the living tree, and the liquid is press-fitted through the water-containing member 3A. It has the advantage that the inner wall of the majority 2 of live trees can be protected. Further, since the liquid substance is injected after removing the internal air, there is an advantage that the liquid substance can penetrate into the green tree 1 more smoothly.

[Third Embodiment] Next, a third embodiment will be described based on FIGS. 8 and 9.

In this third embodiment, the fixing means of the liquid injection guide means 3 in the first embodiment described above uses the wood screw mechanism 11A. It is characterized by having two or more small protrusions 11B and IIB.

An annular recess lID is provided in a part of 1C.

In this case, as shown in FIG.
2 is driven into the majority part 2 of the green tree 1 with a wooden hammer or the like via a predetermined driving member 30. Therefore, due to the action of the interference part 11C, most part 2 of the green tree 1
The liquid injection guide means 3 is effectively fixed by the frictional force between the liquid injection guide means 3 and the liquid injection guide means 3. In addition, in the annular recess 11D, a part of the large portion 2 of the green tree 1 that has been compressed once expands slightly and acts to lock the liquid injection guide means 32.

The other configurations are the same as those of the first embodiment described above.

In this way, the fourth embodiment also has the advantage that the liquid injection guide means 32 is effectively fixed to the green tree 1 and that the workability is very good.

In this fourth embodiment, a cross-shaped low left or annular unevenness may be provided on the outer peripheral portion of the tightening margin portion 11C.
