Description

Closed pressure type tree trunk injector

The invention relates to a closed type pressure type tree trunk injector, in particular to a sealed type pressure type tree trunk injector, wherein a compression barrel is arranged on a bottom surface of a liquid medicine tank integrally formed with an injection tube, so that when a compression barrel is hit by a hammer There is no need to separate the compression sleeves, and there is no concern that the liquid medicine leaks to the outside, and the trees are quickly and easily inserted into the trees, so that the supply of the liquid medicine is smooth, and the mountain trees, parks, and the like with many street trees or trees on the roadside can be improved. The efficiency of large-scale operations on the ground.

In general, trees are prone to debilitation due to pollution caused by various industrial developments and environmental changes caused by soils or various pests and diseases, or in the case where various inorganic nutrients required for the growth of trees cannot be smoothly supplied from the soil. In severe cases, the trees eventually die.

Therefore, in order to prevent trees from getting sick, debilitated or dead, the trees can be grown healthily only by appropriately supplying various therapeutic agents or liquid medicines such as insecticides or nutrients at appropriate times.

The liquid medicine used for this method is a leaf spray unit that sprays the liquid medicine on the leaves of the tree, or a trunk control unit that injects the liquid medicine through the injection hole after the injection hole is formed at a predetermined depth into the stem of the tree. Use. Among them, the trunk control unit is divided into a closed type pressure type trunk injector method and an inflow type trunk injection bottle method.

Among them, the inflow type trunk infusion method is a method in which the chemical solution injected into the inside of the bottle is naturally injected into the pores of the tree through the injection tube under atmospheric pressure, which is selected and used according to the season or tree species. As an example, in the broad-leaved tree, regardless of the season, even if the inflow type trunk is used to inject the bottle, there is only a difference in time, and it is easy to inject the chemical solution into the trunk.

However, in the case of a coniferous tree such as a pine tree, a substance called turpentine on a pine tree in the winter from November to February, that is, the resin stops moving, and even if an inflow type trunk is injected under the condition of no pressure, Injecting the bottle and injecting the liquid smoothly, but from February to November, if the skin of the tree is damaged, in order to protect the damaged part, the resin concentrates on the wound and blocks the liquid medicine, so it is difficult to inject the bottle into the inflow type trunk. For the administration solution, at this time, the liquid can be injected only by using a pressure type trunk injector.

The prior art of the above-mentioned patent document entitled "Korean Patent Publication No. 10-2006-0109385 (published on Oct. 20, 2006), which is assigned to the Japanese Patent No. s. A pressure type trunk injector for trees" (hereinafter, referred to as "Prior Art 1").

In the above-described prior art 1, the support container is provided with a support wall, and a guide portion is formed on the support wall so as to be able to be inserted so as to surround the outer wall of the container body inwardly and outwardly, and is inserted into the discharge port of the container body. The injection pipe is provided with a cutting surface in such a manner that grooves are formed on both sides of the end portion of the insertion portion, and the outer wall of the container body is supported by the side wall and the support wall, so that in any case, there is no fear that the outer wall is cracked, thereby preventing the amount of the agent. When the discharge port of the injection container is inserted into the insertion portion of the injection tube and the bottom surface of the compression container is hit, the barrier wall that blocks the discharge port is easily cut, and the medicine is quickly and smoothly introduced into the tree.

In addition, there is a "pressure type trunk injector" (hereinafter referred to as "prior art 2") of Korean Patent Registration No. 10-1250910 (published on Apr. 05, 2013). The above prior art 2 is a pressure type trunk injector which is configured in such a manner as to screw the injection port into the tree by means of a spiral insertion guide, the pressure type trunk injector comprising: a body container A space portion for accommodating the drug is formed inside, and an injection port blocked by the barrier film is provided at a lower portion of the space portion, and an outer periphery of the injection port is formed by a spiral insertion guide, and a plurality of injections are provided at an end portion of the injection port. In the inlet portion of the groove, a pointed engagement portion is formed to protrude from the inner wall of the space portion connected to the injection port from the space portion; the pressing portion is bonded to the upper portion of the main body container, and the pressing portion is higher toward the upper portion. a plurality of wrinkles are formed in an upwardly protruding arc shape to apply pressure to the space portion; the connecting rod is formed in a longitudinal direction at an inner center of the pressing portion to be housed in a space portion of the body container; and a guiding portion at the connection The lower portion of the rod extends in the longitudinal direction in a "+" shape, the outer side of the guide portion is in a zigzag form, and the end portion of the guide portion is obliquely lined. Cutting.

PRIOR ART DOCUMENT PATENT DOCUMENT Patent Document 1: Korean Patent Publication No. 10-2006-0109385 (published on Oct. 20, 2006), "Peak-type Trunk Injector for Trees" Patent Document 2: Korea Registration No. 10-1250910 No. (Announcement of April 5, 2013) "Pressure Trunk Injector"

However, the above prior art 1 has the trouble of assembling the separated injection tube and the body of the trunk injector each time in order to inject the liquid medicine into the trees. Moreover, the principle of the prior art 1 is to prevent the solution from leaking out by the outer wall of the container body and the support wall of the compression container, but in the case of long-term storage, the gas is generated by the close contact portion between the outer wall and the support wall. The leakage of the chemical solution is because the surface contact portions of the outer wall and the support wall are closely attached rather than sealed.

Further, the prior art 2 has a problem that when a joint failure occurs at one side portion of the pressing portion that is joined to the upper edge of the main body container, there is a fear that the chemical liquid leaks directly to the outside, if the zigzag guide portion and the pointed end are When the engagement state of the engagement portion is relaxed, when the pressing portion is pressed and released to increase the internal pressure, the guide portion is easily detached from the engagement portion, and the pressing portion is returned to the original position, so that the injection of the pressure is smoothly performed. On the contrary, if the guiding portion and the engaging portion are too close to each other, considerable force is required when pressed by hand.

In particular, as in the above-described prior art 2, in the case where the injection port portion having the spiral insertion guide is screwed into the tree one by one and the pressing portion is pressed by hand to perform compression, in the case of an ordinary family having only a few trees Small-scale operations such as garden trees can be realized, but in the case of many tree-shaded trees on the roadside or in many forests, parks, and other places where manual operations are carried out on a large scale, there are swollen hands and arms or considerable fatigue. The sense of physical exertion is large, which makes it difficult to continue the problem of long-term work.

Further, since the pressing portion of the prior art 2 is in a state of being bonded and sealed to the main body container, the leakage of the chemical liquid gas is less likely to occur in the stored state, but when the compression operation is performed, the weak adhesive portion is easily broken. This causes the pressure-type function to be lost due to leakage of the compressed air, and there is a possibility that a chemical accident may occur due to contact between the worker and the liquid phase due to leakage of the chemical solution to the outside.

Further, in the prior art 2, in order to prevent the pressing portion from being broken or the joint portion of the pressing portion from being broken when the pressing portion is directly hit by the hammer, a separate separated sleeve (compression auxiliary sleeve) is added to the back surface of the pressing portion. And the set is hit, but this will cause the efficiency to be quite reduced due to the trouble of the work, so when it is carried out on a large number of street trees or trees, trees, parks, etc. on the roadside, it takes a long time and manpower. It consumes a lot.

In view of the above, the present invention has been developed in order to improve the problems of the prior art described above, and an object of the present invention is to provide a sealed type pressure type trunk injector which integrates an injection tube and a liquid medicine tank even without using separate compression. As long as the sleeve is used to hit a compression bucket integrally formed on the bottom surface of the liquid medicine tank, it is possible to easily set the trees in the case where there is no fear that the chemical liquid leaks to the outside, so that many forests can be provided on the roadside. Large-scale operations are quickly carried out in shaded trees or in forests and parks with many trees.

Another object of the present invention is to provide a sealed type pressure type trunk injector which can obtain high pressure even when the size of the injector is minimized, and does not occur even if the sealed liquid medicine tank is stored for a long time. The phenomenon that the chemical composition is lowered.

The above object of the present invention can be achieved by constituting a hermetic pressure type trunk injector in which the sealed type pressure type tree injector includes a chemical liquid tank, and a pair of engagement grooves are formed at predetermined intervals. A compression tub insertion portion is provided between the outer wall and the inner wall, and the chemical liquid tub and the injection tube integrally formed at the front end of the chemical liquid tank are blocked by the injection barrier film, and are open on the back surface of the chemical liquid tank. Filling the liquid medicine; the liquid medicine barrel sealing cover protrudes in the center of the liquid chemical barrel sealing cover so as to be long toward the injection resisting membrane, and the perforating needle guiding tube whose front end is blocked by the guiding tube blocking diaphragm, the chemical liquid barrel sealing cover and The back edge of the opening of the liquid medicine tank is integrally joined to prevent the chemical liquid from leaking to the outside; and the compression barrel is formed with an engaging protrusion on the outer surface at a corresponding interval from the engaging groove, and is inserted at the center of the compression barrel A perforating needle guide tube and a perforating needle are protruded from the guiding tube barrier diaphragm to compress air, and a flow groove is formed on the outer peripheral surface of the perforating needle so as to be long in the longitudinal direction.

Another object of the present invention can be achieved in that a blocking wing that is in close contact with the outer peripheral surface of the compression tub inserted into the compression tub insertion portion is formed outside the inner wall of the chemical liquid tank to prevent the air in the compression tub from flowing to the outside. A volume reducing projection is formed on the bottom surface of the compression tub, and a volume reducing recessed portion for inserting the volume reducing projection is formed in the chemical tank sealing cover, whereby the moving distance a of the compression tub can be maintained. In the case of increasing the air compression force of the compression barrel.

In this invention, the injection tube is formed integrally with the liquid chemical tank, and the compression barrel hit by the hammer is double assembled outside the liquid chemical tank sealing cover, thereby having the simplicity of not requiring the use of a separate compression sleeve, as long as the hitting The compression barrel, the guide tube barrier film and the injection barrier film are rapidly ruptured together, and the liquid medicine is supplied in a pressure-like manner, so that it is possible to quickly perform large-scale operations in a forest, a park, or the like with many trees or trees. The work efficiency is high, and the construction cost is low due to the reduction of manpower.

Further, there is an effect that the compression moving distance of the compression tub can be maintained even when the size of the injector is minimized by the volume reducing projection of the compression tub and the volume reducing projection of the chemical seal cap, Thereby, the injection of the chemical liquid is smoothly performed by the high air compression force of the compression barrel.

Further, the injection blocking diaphragm for preventing the chemical liquid from leaking out of the liquid medicine tank is located deep inside the injection tube formed integrally, and the chemical liquid barrel sealing cover is covered by the compression barrel for protection, and the air blocking wing double prevents Internal pressure, so when the tree is used for trunk work or when the liquid medicine tank is kept for a long time, there is no fear that the chemical liquid component leaks to the outside, thereby preventing not only the loss of the chemical liquid component, but also effectively preventing the chemical liquid pollution and the like. .

Hereinafter, preferred technical configurations and actions for effectively achieving the object of the present invention will be described in detail with reference to the accompanying drawings. 1 is a transverse cross-sectional view showing a state before a chemical liquid tub and a compression tub are compressed in an example of the present invention, and FIG. 2 is a transverse cross-sectional view showing a state in which the chemical liquid tub of FIG. 1 compresses the compression tub, and FIG. A transverse cross-sectional view of the state in which the liquid chemical tank and the compression tub of Fig. 1 are separated.

As shown in the figure, the sealed type pressure type tree trunk injector of the present invention includes a liquid medicine tank 100 in which an outer wall 110 and a pair of engaging grooves 111 and 112 are formed at predetermined intervals. A compression tub insertion portion 130 is provided between the walls 120, and the chemical liquid tub 100 and the injection tube 140 integrally formed at the front end of the chemical liquid tank 100 are blocked by the injection barrier film 150, and the back surface of the chemical liquid tank 100 is formed. a liquid medicine barrel sealing cover 200, and a perforating needle guiding tube 210 whose leading end is blocked by the guiding tube resistance film 211 is protruded toward the center of the chemical liquid tank sealing cover 200, and the chemical liquid is blocked. The tub sealing cover 200 is integrally joined to the edge of the opening of the back surface of the liquid chemical tub 100 to prevent the chemical liquid from leaking to the outside.

Further, the present invention includes a compression barrel 300 for compressing internal air, and engaging projections 301, 302 are formed at respective intervals on the outer surface of the compression barrel 300 so as to be engaged with the engagement grooves 111, 112. The compression barrel 300 is assembled to the compression barrel insertion portion 130, and a perforating needle 310 protrudes from the guide tube resistance film 211 near the center of the compression barrel 300 near the perforating needle guiding tube 210. The perforating needle 310 can sequentially guide the tube blocking membrane 211 and The injection barrier film 150 is perforated, and a plurality of flow grooves 311 are formed on the outer circumferential surface of the punching needle 310 so as to be long in the longitudinal direction.

Wherein, the bonding unit of the chemical liquid tank 100 and the chemical liquid tank sealing cover 200 may use various bonding units such as a common adhesive, but more preferably, if a well-known ultrasonic welding method is used, the bonding may be performed. The occurrence of defects is minimized.

In the present invention, as shown in FIG. 1, the chemical liquid tank 100 filled with the chemical liquid and the injection tube 140 integrally formed at the front end of the chemical liquid tank 100 are blocked by the injection barrier film 150, and used for The chemical tank sealing cover 200 that closes the opening in the rear of the chemical tank 100 is blocked by the compression tub 300 assembled so that the engaging projections 301 at the distal end are engaged with the engaging grooves 111 at the distal end, and thus is circulated or carried. During the handling, there is no fear that the injection barrier film 150 and the chemical liquid tank sealing cover 200 are deformed, so that the chemical liquid in the chemical liquid tank 100 is safely protected.

Further, when the engaging projection 301 at the front end of the outer peripheral surface of the compression tub 300 is inserted into the engaging groove 111 at the front end of the outer wall 110 of the liquid chemical tank 100, a considerable amount of between the liquid chemical tank sealing cover 200 and the bottom surface of the compression tub 300 is filled. The state of the air.

In this state, in order to use the pressure type trunk injector of the present invention in a tree, if the hole which is previously perforated in the tree is inserted obliquely downward into the injection tube 140, the back surface of the compression barrel 300 is tapped with a hammer or the like ( In the bottom surface, the injection tube 140 is firmly inserted into the hole of the tree, and at the same time, the compression barrel 300 is deeply inserted into the compression barrel insertion portion 130 on the inner circumferential surface of the outer wall 110 of the liquid medicine tank 100 to be inserted.

That is, as shown in FIG. 2, the engaging projection 301 at the front end of the compression tub 300 is inserted so as to be engaged with the engaging groove 111 at the front end of the outer wall 110 of the liquid chemical tank 100, and the rear end of the compression tub 300 is engaged. The protrusion 302 is inserted into the engaging groove 111 at the front end of the outer wall 110, and thus the state in which the compression tub 300 is inserted into the compression tub insertion portion 130 is firmly maintained, and if so, is filled in the bottom surface of the liquid chemical tank sealing cover 200 and the compression tub 300. A considerable amount of air between them presents a compressed state.

Further, as shown in FIG. 1, the front end of the punching needle 310 of the compression tub 300 inserted into the punching needle guide tube 210 is advanced forward by the moving distance a inserted by the compression tub 300, and sequentially passes through the guiding tube barrier film 211 and the injection. The barrier film 150 enters, and thus the guide tube barrier film 211 and the injection barrier film 150 are sequentially broken and perforated.

In the outer peripheral surface of the punching needle 310, the flow groove 311 is formed to be long in the longitudinal direction, so that the compressed air between the liquid chemical tank sealing cover 200 and the compression tub 300 flows into the inside of the liquid chemical tank 100, and compression is applied. The chemical solution of the pressure of the air is also supplied to the tree by the force of the compressed air inserted through the injection tube 140 inserted into the tree through the flow groove 311 inserted into the perforating needle 310 of the barrier film 150, thereby supplying the chemical liquid more smoothly.

In the present invention, as shown in FIG. 3, two or three air blocking wings 121 are protruded from the outer surface of the inner wall 120 of the chemical liquid tank 100, and the plurality of air blocking wings 121 are inserted and inserted in a line contact manner. The inner circumferential surface of the compression tub 300 of the compression tub insertion portion 130 is closely attached, so that when the compression of the compression tub 300 is performed, the reduction of the sliding friction force and the leakage of the compressed air are effectively achieved.

That is, as in the prior art 1, when the blocking mode of the solution and the air is set to be in surface contact, if the adhesion strength in the surface contact is increased, the sliding resistance caused by the friction force when the compression container is pushed into the container body The height is increased, so that a strong force of the hammer is required, and if the adhesion strength is reduced in order to reduce the frictional force, there is a fear that leakage of the solution and the air may occur.

In order to solve such a problem, in the case of the line contact method of the air blocking wing 121, in the case where the chemical liquid tank 100 is formed of a material having elasticity, the line contact manner of the air blocking wing 121 can not only maximize the sealing effect. Moreover, the sliding friction is significantly reduced, so that high-pressure air can be prevented from leaking out, and the compression bucket can be easily pushed in by simply hitting with a hammer.

In this way, when compressing with a hammer in a state where the injector is inserted into the tree, the manner of reducing the sliding friction as much as possible can be regarded as one of the factors which are very advantageous and important for a large number of operations in a large unit.

Further, when the compression tub 300 is compressed, the compressed air inside the compression tub 300 is prevented from flowing out to the outside through the gap between the compression tub insertion portion 130 and the compression tub 300 by the close force of the air blocking wings 121, thus The compressed air pressure within the compression barrel 300 can be maintained very well.

Further, in the process of performing the compression operation of the compression tub 300, even if the weak portion of the adhesive seal of the chemical liquid sealing cover 200 is locally broken, the air blocking wing 121 blocks the compression barrel insertion portion 130 and the compression barrel by the double protection. The gap between the 300s does not cause the loss of compressed air or chemical liquid, thereby effectively preventing the safety accident caused by the maintenance of the function of the compressed air and the outflow of the chemical liquid.

Further, in a state where the liquid chemical tub 100 is sealed by the chemical liquid tank sealing cover 200, the air and air blocking wings 121 of the compression tub 300 are also sealed to protect the outside of the liquid chemical tank sealing cover 200, so that even the pressure type trunk The storage period of the injector continues for a long time, and there is no fear that the chemical liquid component in the chemical liquid tank 100 flows out to the outside, and there is no fear that the chemical liquid component is lowered.

Further, as shown in FIGS. 1 and 2, it is preferable that a volume reducing projection 320 is formed on the bottom surface of the compression tub 300, and a concave portion 220 is formed in the chemical tank sealing cover 200, when the compression tub 300 is compressed, The recessed portion 220 inserts the volume reducing projection 320.

Then, the total volume inside the compression tub 300 can be minimized while the moving distance a of the compression tub 300 is maintained, so that when the compression tub 300 is pushed into the compression tub 300 of the liquid medicine tub 100, The air compression force can be maximized as much as possible.

Such a volume reduction projection 320 may be referred to as a pressure enhancement adjustment portion, and if the above-described volume reduction projection 320 is utilized, it is possible to provide a pressure type trunk injector capable of obtaining high pressure while minimizing the overall size. .

Here, the punching needle 310 may protrude upward in the center of the volume reducing projection 320, but is preferably formed from the bottom center portion of the compression tub 300 toward the inner center of the volume reducing projection 320 for When the support portion 330 of the punching needle 310 is supported, the force when the compression barrel 300 is hit by the hammer is uniformly transmitted to the punching needle 310 through the support portion 330, so that the guide tube resisting film 211 and the injection blocking film 150 can be easily broken.

Further, the tip end of the injection pipe 140 is in the form of a tripod in which the cutting portion 141 having a predetermined depth is provided in three directions, and an insertion blocking shoulder is formed on the outer circumferential surface of the injection pipe 140 at a predetermined interval from the cutting portion. 142.

Then, when the injection tube 140 is inserted into the hole of the tree, it functions to support the injection tube 140, and the chemical liquid is dispersed to the vicinity of the bark of the sap portion, and the front end of the injection tube 140 having the tripod shape by the cut portion 141 has The soft elasticity makes it possible to prevent the side leakage of the chemical solution due to the fact that a part of the injection tube is inserted into the tree hole as it is not deeply inserted.

Further, when the hammer 140 is struck to insert the injection tube 140 into the hole of the tree, the insertion of the barrier shoulder 142 is not inserted, and it is always inserted only at a predetermined depth, thereby causing the tree to be inserted. The shape is uniform, and the supply state and effect of the chemical solution are regulated.

4 and 5 illustrate a pressure type trunk injector that separates the liquid medicine tank of the present invention into a chemical liquid outer tub and a chemical liquid inner tub.

In other words, the chemical liquid tub 100 is formed of the chemical liquid outer tub 100a and the chemical liquid inner tub 100b, and the chemical liquid outer tub 100a is formed with the outer walls 110 and the inner walls 110 of the pair of engaging grooves 111 and 112 at predetermined intervals. A compression tub insertion portion 130 is provided between the walls 120, and an injection tube 140 is integrally formed at a distal end of the chemical liquid outer tub 100a. The chemical liquid inner tub 100b is disposed inside the chemical liquid outer tub 100a, and the chemical liquid inner tub 100b The front end of the injection pipe 140 is closed by the injection barrier film 150, and the rear opening portion of the chemical liquid inner tub 100b is integrally joined to the rear end of the chemical liquid outer tub 100a to fill the chemical liquid. At this time, the chemical liquid tank sealing cover 200 The edge of the back surface opening of the chemical liquid inner tub 100b is integrally joined to prevent the chemical liquid in the chemical liquid inner tub 100b from leaking to the outside.

In the present invention, as shown in FIG. 4, the injection barrier film 150 at the front end of the chemical liquid inner tub 100b filled with the chemical liquid is located deep in the injection pipe 140 of the chemical liquid outer tub 100a, and is sealed by the chemical liquid tank. The opening portion of the back surface of the inner tub 100b is blocked, and the compression tub 300 is further disposed outside the liquid chemical tank sealing cover 200. Therefore, the above-described injection barrier film 150 and the chemical liquid tank sealing cover 200 are not generated during the circulation or carrying and carrying. The fear of deformation, so that the liquid medicine in the inner tank 100b of the liquid medicine is very safely protected.

Further, in order to use the pressure type trunk injector in the tree, if the hole for which the tree is previously perforated is inserted into the injection tube 140 in an inclined downward direction, and the back surface (bottom surface) of the compression barrel 300 is tapped with a hammer, the compression barrel 300 The compression tub insertion portion 130 of the liquid medicine tub 100 is inserted in a deeply inserted manner, and at the same time, the injection tube 140 is deeply inserted into the hole of the tree. At this time, as shown in FIG. 5, as described above, the engaging projections 301 and 302 that are engaged with the pair of engaging grooves 111 and 112 are firmly held to maintain the insertion state of the compression tub 300, thereby making it firm. The state in which the air inside the compression tub 300 is compressed is maintained.

Further, as described above, the front end of the punching needle 310 of the compression tub 300 inserted into the punching needle guiding tube 210 advances forward by the moving distance a of the compression tub 300, and sequentially blocks the injection of the guiding tube blocking diaphragm 211 and the chemical liquid inner tub 100b. The film 150 is perforated.

Further, as described above, the compressed air inside the compression tub 300 flows into the inside of the chemical liquid inner tub 100b by the plurality of flow grooves 311 formed on the outer circumferential surface of the punching needle 310 so as to be long in the longitudinal direction, in the liquid medicine. The chemical solution of the tub 100b is more smoothly supplied and injected into the tree through the injection pipe 140 inserted into the tree by the pressure of the compressed air.
