Description

  The present invention relates to a method for treating a xylem by injecting a treatment liquid such as an antifungal agent or an antiseptic into the xylem, and a wood screw nozzle used therefor.

  There is a known method for extinguishing termites lurking in an ant road provided by termite damage in a wooden building by spraying an anti-anticide at a high pressure from the tip of a spray gun (Patent Document) 1 etc.).

  This spray gun is supplied with a ant repellant pumped using a power source such as an engine or motor, and the ant repellant only while the worker holding the spray gun is inserted into the hole in the ant path. Injection is performed.

  On the other hand, in Patent Document 2, the wooden part of the wooden building is perforated downward, and the neck portion of the container filled with the antiseptic / anticide is inserted into the hole, so that the antiseptic / antiseptic agent is applied by natural flow. A processing method for injecting into a xylem is disclosed.

  Furthermore, in Patent Document 3, the wooden pillar is surrounded by a protective material with a bottom in a state where a gap is provided, and an antiseptic is impregnated into the inner core portion of the wooden pillar by injecting a preservative into the gap. The method of letting it be disclosed is disclosed.

  However, in the method of injecting the treatment liquid into the hole at high pressure, the treatment liquid cannot penetrate into the inside because the penetration rate of the xylem is small. On the other hand, in the method in which the tip of the container containing the processing liquid is inserted into the hole and injected by natural flow, the injection can be performed only on the upper surface of the xylem. Furthermore, a timber used as a beam or a pillar in a wooden building or the like cannot be put into a pressure vessel or the like.

  Accordingly, an object of the present invention is to provide a wood processing method and a wood screw nozzle that can be easily applied to a wood part in any state and has a high treatment liquid permeation performance.

  In order to achieve the above object, a xylem processing method of the present invention is a xylem processing method for injecting a treatment liquid into a xylem, the step of making a hole in the xylem, A step of fixing an injection device filled with the processing liquid having a pressurizing means; and a step of infiltrating the processing liquid into the xylem by the pressurizing means. The treatment liquid is injected over time. Here, the said pressurization means can be set as the structure which provides a pressure with the restoring force of a spring or rubber | gum.

  The invention of a wood screw nozzle and a wood part processing method using the wood screw nozzle is a wood screw nozzle used when injecting a processing liquid into the wood part, and has a wood screw part having a through hole penetrating in the axial direction. An adapter part for connecting to the container filled with the processing liquid provided on the rear end side of the wood screw part, and a connecting pipe part for connecting between the wood screw part and the adapter part The connecting pipe part is formed on a tapered peripheral surface extending from the wood screw part toward the adapter part.

  Here, it can be set as the structure provided with the elastic water stop ring with which the said wood thread part or the said connection pipe part is mounted | worn. Moreover, it can be set as the structure by which at least a pair of opposing plane part is formed in the outer periphery of the said adapter part.

  The xylem treatment method of the present invention configured as described above fixes the injection device filled with the treatment liquid into the hole formed in the xylem, and injects the treatment liquid at a low pressure for a long time by the pressurizing means. Let

  Since the pressurizing means is provided in this way, the treatment liquid can be injected also from the side surface and the lower surface of the xylem. Further, since the injection device is fixed in the hole, the injection can be continued as long as the treatment liquid continues to penetrate, and the treatment liquid can be sufficiently infiltrated.

  In addition, if the pressing means is configured to apply pressure by the restoring force of a spring or rubber, it can be applied not only to a separate power source but also to a xylem in a narrow place.

  Furthermore, the invention of the wood screw nozzle connects a wood screw portion having a through hole penetrating in the axial direction, an adapter portion for connection to a container filled with a processing liquid, and the wood screw portion and the adapter portion. A connecting pipe part, and the peripheral surface of the connecting pipe part is formed in a taper shape extending toward the adapter part.

  For this reason, it is possible to fix the wood screw nozzle while providing a hole with the wood screw portion without causing a crack or the like in the wood portion. Moreover, if screwed into the wood part by the wood screw part, it can be fixed to the lower surface of the wood part for a long time. Furthermore, since the tapered connecting pipe portion is pushed in and is brought into close contact with the hole after the wood screw portion is screwed in, the treatment liquid can be leaked only by screwing.

  Further, if an elastic water stop ring is attached to the wood screw part or the connecting pipe part, the water stop performance can be further improved by bringing the elastic water stop ring into close contact with a hole formed in the wood part. .

  Furthermore, if at least a pair of opposed flat portions are formed on the outer periphery of the adapter portion, the wood screw portion can be easily screwed into a hard wood portion using a tool such as a wrench.

It is sectional drawing explaining the processing method of the xylem of this Embodiment. It is the figure which showed the side surface and the rear surface in order to demonstrate the structure of the wood screw nozzle of this Embodiment. It is a perspective view explaining the process of attaching a wood screw nozzle to a wood part. It is a side view explaining the injection | pouring apparatus of the state with which the termite preventer was filled. It is a side view explaining the injection apparatus of an Example. It is a side view explaining another injection device of an example.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram for explaining the processing method of the xylem W of the present embodiment. Here, the timber W is made of wood, such as timber, plywood, laminated timber, or single-ply laminated material, or timber made by using cut-out trees such as timber and square plate for building and product materials, etc. Is applicable.

  On the other hand, in the processing liquid M injected into the xylem W, an ant or insecticide for controlling termites and the like, an antiseptic for preventing the erosion of the xylem W, and generation of mold on the xylem W are suppressed. Examples thereof include a fungicide and a resin material such as an epoxy resin that is injected to modify or reinforce the xylem W.

  In the xylem W processing method of the present embodiment, the processing liquid M is injected into the xylem W for a long time at a low pressure. Here, “long time” is compared with a short time (several seconds to several minutes) in which injection is performed only when the operator pulls the lever, such as when an anti-fungal agent is injected with a spray gun or the like. It is the length of time expressed. For example, it refers to a relatively long time such as several hours, preferably several days or months. In short, the time until the processing liquid M filled in the injection device 2 is sufficiently permeated into the xylem W corresponds to a long time.

  On the other hand, “low pressure” is the magnitude of pressure expressed in contrast to high pressure (2-3 MPa) using a power source such as a compressor, such as when spraying an ant-proofing agent with a spray gun or the like. For example, it refers to a relatively small pressure of about 1 Pa or less, and further 0.5 Pa or less.

  The injection device 2 having a low-pressure pressurizing device refers to a device that applies pressure by a restoring force of an elastic material such as a spring or rubber and can pressurize without requiring a power source.

  If the injection device 2 can pressurize without the need for a power source, the injection can be continued for a long time from the injection device 2 fixed to the xylem W wherever the xylem W is located. it can.

  The injection device 2 shown in FIGS. 1 and 4 is a device having a pressurizing means that uses the restoring force of a spring. The injection device 2 includes a cylindrical cylinder portion 21 that serves as a container for the processing liquid M, a string-wound spring portion 22 that generates spring pressure, and a piston portion 23 that is attached so as to be able to reciprocate within the cylinder portion 21. And is mainly composed of

  The cylinder part 21 is formed of a transparent or translucent material so that the amount of the processing liquid M filled in the inner space can be easily understood. A cylindrical connection port portion 211 that is thinner than the main body is formed at the tip of the cylinder portion 21. A screw groove for connecting to a wood screw nozzle 1 described later is provided on the peripheral surface of the connection port portion 211.

  On the other hand, a lid portion 212 that can be attached to the main body without hindering the reciprocating motion of the piston portion 23 is provided at the rear end of the cylinder portion 21. The rear end of the string spring portion 22 is brought into contact with the inner surface of the lid portion 212.

  The piston portion 23 is provided at the plug portion 231 on the connection port portion 211 side of the cylinder portion 21, a shaft portion 232 that is joined to the back surface of the plug portion 231 and protrudes from the lid portion 212, and a rear end of the shaft portion 232. The rear end metal fitting 233 and the stopper portion 234 provided on the shaft portion 232 are mainly configured.

  The plug part 231 is a plug that is slidably in close contact with the inner peripheral surface of the cylinder part 21, and the treatment liquid M filled between the connection port part 211 and the plug part 231 is directed to the shaft part 232 side. It has a function to prevent leakage. The plug body 231 includes, for example, a cone on the connection port 211 side and a cylindrical body on the shaft 232 side by an elastic body such as rubber.

  One end of the shaft portion 232 is connected to the center of the cylindrical body of the plug portion 231, and the other end protrudes outside the cylinder portion 21 through a hole (not shown) provided in the lid portion 212.

  As shown in FIG. 4, the shaft portion 232 is provided with a pair of stopper portions 234 and 234. The stopper portions 234 and 234 are provided in a trapezoidal shape that is line-symmetrical at an intermediate position of the shaft portion 232.

  The lid portion 212 is provided with a rectangular hole (not shown) for allowing the stopper portions 234 and 234 to pass through the circular hole that allows the cylindrical body of the shaft portion 232 to pass therethrough. By rotating the shaft portion 232 and adjusting the positions of the stopper portions 234 and 234 to the positions of the rectangular holes, the shaft portion 232 can be pulled out largely.

  Here, between the plug body portion 231 and the lid portion 212, the string winding spring portion 22 is interposed. When the shaft part 232 is largely pulled out from the cylinder part 21, the distance between the plug part 231 and the lid part 212 is shortened, and the chord spring part 22 is contracted. That is, the restoring force of the string spring portion 22 can be applied.

  In contrast, when the stopper portions 234 and 234 are removed from the positions of the rectangular holes by rotating the shaft portion 232, the stopper portions 234 and 234 come into contact with the outer surface of the lid portion 212 and the movement of the piston portion 23 is stopped. (No pressure state).

  When the shaft portion 232 is further rotated to align the stopper portions 234 and 234 with the positions of the rectangular holes, the stopper portions 234 and 234 pass through the lid portion 212 and enter the inner space of the cylinder portion 21, and the plug body portion 231. Moves toward the connection port 211.

  At this time, if the processing liquid M is filled between the plug body portion 231 and the connection port portion 211 inside the cylinder portion 21, the processing liquid M is connected to the connection port portion 211 by the pressure generated by the movement of the plug body portion 231. It will be discharged from.

  The force for discharging the treatment liquid M is a low pressure applied by the restoring force of the spring of the string spring portion 22. The restoring force of the spring by the coiled spring portion 22 can be exhibited not only when the injection device 2 is directed downward, but also when it is directed laterally or upward. That is, by using the injection device 2, not only downward but also lateral or upward injection can be performed.

  The injection device 2 and the wood part W having such a configuration are connected by the wood screw nozzle 1 of the present embodiment. As shown in FIGS. 1 and 2, the wood screw nozzle 1 includes a wood screw portion 11 having a through hole 111 penetrating in the axial direction, an adapter portion 12 provided on the rear end side of the wood screw portion 11, and a wood screw portion. 11 and the adapter part 12 and a rubber ring 14 as an elastic water-stop ring attached to the wood screw part 11.

  The external shape of the wood screw portion 11 is generally formed in the same shape as that screwed into a timber or the like as a wood screw. On the other hand, a through hole 111 for allowing the processing liquid M to flow down and discharge from the inlet 112 is provided inside the wood screw portion 11. For example, a wood screw portion 11 having a diameter of about 3 mm to 5 mm and a length of about 10 mm to 20 mm can be provided.

  A communication hole 131 connected to the through hole 111 is provided in the connecting pipe portion 13 along the axial direction. On the other hand, as shown in FIG. 2, the outer shape of the connecting pipe portion 13 is formed on a tapered peripheral surface 132 that extends in a tapered shape from the wood screw portion 11 toward the adapter portion 12. That is, the outer shape of the connecting pipe portion 13 is formed in a truncated cone shape with respect to the cylindrical wood screw portion 11.

  A rubber ring 14 is attached to the rear end of the wood screw portion 11 or the front end of the connecting pipe portion 13. The rubber ring 14 is formed in an annular shape by an elastic material such as silicon rubber. When a force for moving in the direction of the adapter portion 12 is applied to the rubber ring 14 attached to the wood screw portion 11, the rubber ring 14 rises up the tapered peripheral surface 132 of the connecting pipe portion 13.

  At this time, since the taper circumferential surface 132 becomes a movement resistance, the rubber ring 14 can be elastically deformed and brought into close contact unless the force applied to the adapter portion 12 exceeds the movement resistance.

  On the other hand, the adapter part 12 is a joint part for connecting to the injection device 2 which is also a container filled with the processing liquid M. A threaded groove 124 is provided on the inner peripheral surface of the connecting tube portion 13 in the communication hole 121 penetrating in the axial direction of the adapter portion 12 so that the tip of the connection port portion 211 can be screwed.

  By connecting the connection port portion 211 and the adapter portion 12, the processing liquid M filled in the cylinder portion 21 is supplied to the connection port portion 211, the communication hole 121 of the adapter portion 12, the communication hole 131 of the connection tube portion 13, and the wood. The through hole 111 of the screw part 11 can be caused to flow down and discharged from the injection port 112.

  Further, as shown in the rear view on the right side of FIG. 2, a pair of opposed flat surface portions 122 and 122 and a flange portion 123 are formed on the outer periphery of the adapter portion 12. That is, the adapter part 12 is shape | molded by cross-sectional view substantially long hole shape. The wood screw portion 11 can be easily screwed into the wood portion W by applying a surface of a tool such as a wrench R to the flat portions 122 and 122.

  Next, the processing method of the wood part W using the wood screw nozzle 1 of this embodiment, the processing method of the wood part W, and the operation of the wood screw nozzle 1 will be described.

  First, the worker goes to a place where the xylem W to be processed exists. For example, when it is carried out between the foundation of a wooden building and the floor on the first floor, it enters the underfloor space on the first floor, and when it is carried out under the upper floor or behind the ceiling, the surface of the wood part W to be processed is Enter the exposed space.

  When a hole such as an ant road is opened on the surface of the wood part W, the tip (injection port 112) of the wood screw part 11 of the wood screw nozzle 1 can be directly applied to the hole. Further, after drilling a pilot hole having a diameter of about 3 mm with respect to the hole of the ant road, the process may proceed to a step of screwing the wood screw portion 11 having a diameter of, for example, about 4 mm. By drilling the pilot hole longer than the wood screw portion 11, the penetration range of the treatment liquid M can be easily expanded.

  Further, even when a thin ant road having a diameter of about 1 mm to 2 mm extends to a deep part, the penetration range of the treatment liquid M can be expanded along the ant road. Furthermore, even in a place where there is no hole in the ant path, the tip of the wood screw portion 11 can be brought into contact with the surface of the wood portion W, or a pilot hole can be drilled, and then the following process can be performed.

  Subsequently, the wood screw nozzle 1 is rotated to screw the wood screw portion 11 into the wood portion W. If it is difficult to rotate manually, the wood screw nozzle 1 can be easily rotated by fitting the wrench R to the flat surface portions 122, 122 outside the collar portion 123 of the adapter portion 12, as shown in FIG. It becomes like this.

  Here, when a cone-shaped nozzle is driven into the hole of the ant road with a hammer or the like, the wood part W may be cracked or chipped by an impact. On the other hand, when the wood screw part 11 is screwed in, it is possible to prevent the wood part W from being cracked or chipped.

  Moreover, since the joining strength by the screwing performed while providing a hole by the wood screw part 11 has high joining strength, the wood screw nozzle 1 can be firmly fixed. That is, since the bonding strength that can withstand the dead weight of the injection device 2 filled with the processing liquid M can be easily exhibited, the side surface and the lower surface of the xylem W can be used as the processing target surface.

  When the wood screw portion 11 is screwed into the wood portion W in this way, the connecting pipe portion 13 following the wood screw portion 11 becomes a tapered peripheral surface 132 in which the adapter portion 12 side is widened. It can be in the state where it was blocked by the connecting pipe part 13 at the inlet. Further, after the rubber ring 14 attached to the rear end of the wood screw portion 11 comes into contact with the surface of the wood portion W, the rubber ring 14 is pushed up along the tapered peripheral surface 132 and elastically deformed, and the wood portion W is formed. It can be in close contact with the drilled hole to fill the gap.

  Since the gap between the hole can be filled with the tapered peripheral surface 132 of the connecting pipe portion 13 and the rubber ring 14 simply by screwing the wood screw nozzle 1 into the wood portion W in this way, the processing liquid M is connected to the wood screw portion 11 or the connecting portion. Leakage from between the tube portion 13 and the hole can be prevented.

  FIG. 4 shows the injection device 2 in a state where the processing liquid M is filled. The worker can fill the injection device 2 with the processing liquid M before entering the underfloor space or the like. When filling the processing liquid M, the connection port 211 is inserted into the container of the processing liquid M, and the piston part 23 is pulled backward by holding the rear end metal fitting 233, so that the processing liquid is placed in the space in front of the plug body 231. M can be filled.

  The piston portion 23 can stop applying the restoring force of the chord spring portion 22 by rotating the shaft portion 232 such that the stopper portions 234 and 234 are hooked on the lid portion 212. That is, the state in which the processing liquid M is filled is maintained.

  And the injection apparatus 2 is fixed by screwing the front-end | tip of the connection port part 211 with respect to the adapter part 12 of the wood screw nozzle 1 screwed in the wood part W. FIG. If the wood screw portion 11 of the wood screw nozzle 1 is firmly joined to the wood portion W, it does not come off even if the weight of the injection device 2 and the processing liquid M acts as it is, and is injected into the hole of the wood portion W. The state where the device 2 is fixed can be maintained.

  When the shaft part 232 of the piston part 23 is rotated and the restriction of the movement by the stopper parts 234 and 234 is released in the state where the injection device 2 is fixed in this manner, the plug part 231 is restored to the restoring force of the string spring part 22. Then, it starts to move toward the connection port 211.

  Then, as shown in FIG. 1, the processing liquid M discharged from the injection port 112 of the wood screw nozzle 1 is injected into the wood part W. The permeation speed and permeation range of the treatment liquid M vary depending on the material and state of the xylem W (the length and spread of the ant road, the degree of deterioration of the xylem W, the length of the pilot hole, etc.).

  Even if the processing liquid M flows through the gap between the wood screw portion 11 and the hole to the surface side of the wood portion W, the gap is blocked by the tapered peripheral surface 132 and the rubber ring 14 of the connecting pipe portion 13. Therefore, the processing liquid M can be permeated toward the deep part of the xylem W without leaking.

  As described above, since the state of being pressurized at a low pressure is maintained by the restoring force of the string spring portion 22, the processing liquid M can be gradually spread to the deep portion of the wood portion W. That is, since the penetration rate of the treatment liquid M is low in the xylem W, even if it is injected in a short time at a high pressure, it can only be rebounded and cannot penetrate into the inside. Further, the injection can be performed in accordance with the penetration speed of the xylem W, and the treatment liquid M can be sufficiently permeated. Furthermore, the permeation range of the treatment liquid M can be easily expanded by perforating the pilot hole to be drilled before the wood screw nozzle 1 is screwed into the deep part of the wood part W.

  In addition, when the diameter of the hole of the ant road is as small as about 1 mm to 2 mm, the treatment liquid M can hardly be injected at a high pressure. Can penetrate. Furthermore, regardless of the presence or absence of holes in the ant path, for example, the treatment liquid M such as an ant-repellent agent is infiltrated into the xylem W by low pressure injection at a predetermined interval such as a fixed interval, thereby preventing the termites from ambushing. Can be processed. That is, if the termites reach the area where the ant trails are stretched and penetrated with the termite-proofing agent, they can be eliminated when they pass.

  And when long time passes and the process liquid M in the cylinder part 21 runs out, the injection apparatus 2 and the wood screw nozzle 1 are removed and removed. If necessary, the treatment liquid M can be refilled in the injection device 2 and set in the wood screw nozzle 1 again.

  The processing method of the wood part W using the wood screw nozzle 1 of this embodiment configured as described above includes the injection device 2 in which the treatment liquid M is filled in the hole opened in the wood part W by the wood screw nozzle 1. The processing liquid M is injected into the xylem W for a long time with a low pressure by the restoring force of the string spring 22.

  For this reason, the treatment liquid M can be injected also into surfaces other than the upper surface such as the side surface and the lower surface of the xylem W. Further, since the injection device 2 is fixed to the hole of the wood part W by the wood screw part 11, the injection can be continued stably as long as the penetration of the treatment liquid M continues, and the treatment liquid M can be sufficiently infiltrated. .

  Further, since the pressurizing means is configured to apply pressure by the restoring force of the string spring portion 22, a power source such as a compressor is not required separately. Furthermore, it suffices if there is a space in which the injection device 2 can be disposed, and the present invention can be applied to a xylem W in a narrow place such as an underfloor space or a ceiling space.

  In particular, if the ceiling space or the attic space gets wet with chemicals by spraying or spraying, the lower room may be soiled. However, in the case of the wood screw nozzle 1 of the present embodiment, the tapered peripheral surface 132 and the rubber ring are used. The water leakage treatment is performed by 14. In addition, if low-pressure injection is used, the treatment liquid M is slowly permeated into the wood structure and the ant road at a low pressure, so that overflow of the treatment liquid M can be minimized and the lower chamber There is no risk of fouling and it can be used safely for a long time.

  Further, when the xylem W is a tree, it is weakened by applying the treatment method of the xylem W of the present embodiment in which the treatment liquid M such as a vital agent or a nutrient is injected over a low pressure for a long time. It can give vitality to trees effectively.

  Furthermore, as long as the injection device 2 is hung from the lower surface of the wood part W as long as it is screwed into the wood part W by the wood screw part 11, it can be stably fixed for a long time.

  Moreover, the peripheral surface of the connecting pipe part 13 which connects between the wood screw part 11 and the adapter part 12 is formed in the taper shape which spreads toward the adapter part 12, and therefore the hole opened in the wood part W is formed. The water leakage treatment of closing the inlet with the tapered peripheral surface 132 and further bringing the rubber ring 14 into close contact can be performed simultaneously with the screwing.

  Further, if at least a pair of opposed flat portions 122, 122 are formed on the outer periphery of the adapter portion 12, the wood screw portion 11 can be easily attached to the hard wood portion W using a tool such as a wrench R. Can be screwed in.

  If high pressure injection is performed on the xylem W whose strength has been reduced due to ant roads or deterioration, the xylem W may be destroyed by high pressure. On the other hand, it is possible to reinforce the wood part W without damaging the wood part W by allowing the adhesive such as an epoxy resin to penetrate into the deep part of the wood part W for a long time as the treatment liquid M. Furthermore, the xylem W can be modified by injecting a reinforcing resin material into the xylem W having weak materials or nodes or back cracks.

  Hereinafter, an example in which injection devices 3 and 4 of a form different from the injection device 2 described in the above embodiment are used will be described with reference to FIGS. 5 and 6. Note that the description of the same or equivalent parts as the contents described in the above embodiment will be described using the same terms or the same reference numerals.

  The injection device 3 shown in FIG. 5 is a device having a pressurizing means using the restoring force of rubber. The injection device 3 is mainly composed of a cylindrical cylinder part 31, a pair of pressure rubbers 32, 32 for generating rubber pressure, and a piston part 33 attached so as to be able to reciprocate within the cylinder part 31. Configured.

  The cylinder part 31 is formed of a transparent or translucent material so that the amount of the processing liquid M filled in the inner space can be easily understood. A cylindrical connection port portion 311 that is thinner than the main body is formed at the tip of the cylinder portion 31. A thread groove for screwing into the adapter part 12 of the wood screw nozzle 1 is provided on the peripheral surface of the connection port part 311.

  The piston part 33 protrudes laterally from the plug part 331 on the connection port part 311 side of the cylinder part 31, the main body part 332 joined to the back surface of the plug part 331, and the rear end part 333 of the main body part 332. The rear hooks 35 and 35 are mainly configured.

  A pair of front hooks 34, 34 project laterally from the rear hooks 35, 35 on the connection port 311 side of the cylinder portion 31 body. The front hooks 34 and 34 and the rear hooks 35 and 35 can be opposed to each other at the same time, and the rubber band pressure rubber 32 is hooked on the opposed front and rear hooks 34 and 35. .

  When carrying out the processing method of the xylem W using this injection device 3, for example, with the connection port 311 inserted into the container of the processing liquid M, the piston 33 is held with the rear end 333. Pulling backward, the processing liquid M is filled in the space in front of the plug body 331.

  Then, the connection port portion 311 is screwed into the adapter portion 12 of the wood screw nozzle 1 screwed into the wood portion W, and the injection device 3 is fixed to the wood portion W. In this state, when the pressure rubbers 32, 32 are stretched and hooked between the front hooks 34, 34 and the rear hooks 35, 35, the restoring force of the stretched rubber acts on the piston portion 33. It will be in the state pressurized by the low pressure by the pressure rubber 32,32.

  The pressure rubbers 32, 32 are preferably arranged evenly on the left and right sides in order to maintain pressure in a balanced manner, but the number of hooks between the pair of front hooks 34 and rear hooks 35 is limited to one. It is not something. The magnitude of the applied pressure can be adjusted by the number of the pressure rubbers 32 to be hooked.

  On the other hand, the injection device 4 shown in FIG. 6 is a device having a pressurizing means using the restoring force of rubber, like the injection device 3. The injection device 4 is mainly configured by a cylindrical rubber tube 41, a connection port portion 42 provided at the front end portion 411 of the rubber tube 41, and a filling port portion 43 provided at the rear end portion 412 of the rubber tube 41. Is done.

  Before the treatment liquid M is filled, the rubber tube 41 is in a contracted state as indicated by a two-dot chain line in FIG. In this contracted state, the connection port portion 42 is screwed into the adapter portion 12 of the wood screw nozzle 1 screwed into the wood portion W, and the injection device 4 is fixed to the wood portion W.

  And if the container of the process liquid M is connected to the filling port part 43 provided with the non-return valve (illustration omitted) and it inject | pours with respect to the rubber tube 41, with the process liquid M which cannot osmose | permeate the xylem W immediately.
