The present invention mainly relates to a drug syringe for removing harmful plants in forests, which is capable of removing scabs by injecting scavenging drugs by killing them after they are interspersed with forests and hindering the growth of trees. Investigating the forest with the connecting hose of the drug container connected to the handle of the syringe, when the patient finds a prick, he injects the drug with a simple operation by stabbing the root of the puff with a syringe.

In general, in terms of forest protection, the removal of a plant is a source that hinders the growth of trees. Therefore, its removal is the source of protection and development of forests. However, in the past, a method of digging or cutting the root roots was removed by using a shovel, a hoe, or a rob, but such a method has to be dug out of the root roots. There was a drawback that the removal process was inefficient, and in recent years, the syringe is used as a method of killing the needle with a drug for removing the needle, but the needle is thin and weak, so If you can't inject flowers Since the drug is invaded by inserting a needle into the drilled hole and then inserting a needle into the drilled hole, the removal work is very cumbersome and takes a long time.

Therefore, the present invention has been devised to solve the above-mentioned shortcomings, and the upper part of the piston tube is connected to the lower end of the injection tube which connects the connection hose for injecting the drug in the drug container into the piston tube to one end of the handle. The outflow hole is attached to the lower part of the piston tube so that the cylinder 된 can be lifted up and down on one side of the tip, and the lower part of the piston tube protrudes into the incision groove facing the piston and the lower part and is fixed to the cylinder. An extruded ball valve is installed in the lower part of the piston tube, and a hatch that inserts a needle into the needle bar is attached to the lower part of the piston tube. When they are stabbed, the cylinder acts synergistically, causing the check valve to act ascendant to inhale the drug. When the pressure applied to the handle is applied, the cylinder is lowered to operate the lowering of the check valve to extrude the previously inhaled drug. The drug is injected into the outlet hole of the needle rod embedded in the needle root through the needle. In particular, the present invention inserts a needle that directly ejects the drug into a needle with a large diameter, so the needle is broken or blocked because the needle does not come in direct contact with the root of the drug during injection. Does not occur, and the user can inject the drug by one operation to stab the needle into the root of the drug, so that the drug injection operation is very easy to double the efficiency of the detonation operation, which will be described in detail according to the accompanying drawings. Is as follows.

Handle (1) One end of the air discharge control opening (3) for opening and closing the air outlet hole (2) of the upper part and the fastener (5) is screwed to the hose connector (4) of the other end, and communicates with the inside of the handle (1) An upper threaded portion 9 'of the piston tube 9, to which the screwed portion 8' of the adjuster 8 is screwed, is screwed into the upper connector 7 attached to the lower portion of the injection tube 6, and the piston tube ( In the lower large diameter tube portion 9 "of the 9), the upper portion of the upper cylinder 10a is caught by the outer catching jaw 9a, but the screwed portion 8 'of the adjusting opening 8 screwed to the upper threaded portion 9'. A compression spring 13a is held between the bottom 12 and the cylinder 12 inserted above the upper cylinder 10a caught by the outer locking jaw 9a.

An inner locking jaw 9b is formed above the guide tube 14 which is inserted into the upper threaded portion 9 'of the piston tube 9 in a sliding manner, and the shank valve 15 attached to the lower end of the guide tube 14 is formed. Both protrusions 15 'are projected into the incision grooves 16 long cut on both sides of the lower large diameter tube portion 9' 'and the lower cylinder 10b is fixed to the lower end of the upper cylinder 10a. ') To be fixed to the insertion, the check valve 15 is elastically installed by the compression spring (13b).

The suction ball valve 17 which opens and closes the suction valve hole 15 ″ of the check valve 15 is attached to the cap 18 having the extruded hole 18 ′ attached to the lower part of the check valve 15. The suction valve hole 15 "is closed by the spring 19, and the lower part of the shank valve 15 is inside the lifting hole 20 attached to the lower large diameter pipe portion 9" of the piston pipe 9. It was configured to slide, the hatch 20 is an extrusion valve ball 20 'and the extrusion ball valve 21 for opening and closing it is held by a spring (22).

In addition, the injection needle 23 formed at the lower portion of the hatch 20 can be lifted and lowered in the needle bar 25 having the flange 25 ′ inserted into the lower side of the lower cylinder 10b and fixed to the cap nut 24. The ejection hole 25 "of the needle bar 25 is formed long in the side wall of the tip part upper part.

Hereinafter, reference numerals 26 and 27 denote annular packings bound to the upper portion of the guide tube 14 and the lower portion of the shank valve 15, and 28 and 28 'denote the through holes formed in the lower cylinder 10b.

The present invention configured as described above is inserted into the hose connector (4) of the handle (1) of the connection hose connected to the drug container (not shown) that the forest garden is held on the back, and then bound to the drug container (5) The injected drug is injected into the handle 1 through the connection hose and flows into the guide tube 14 and the check valve 15 inserted into the piston tube 9 through the injection tube 6. At this time, when injecting the drug of the medicine container into the shank valve 15 through the handle (1), the air discharge hole (2) is opened by slightly loosening the air discharge control (3) attached to one end of the handle (1). When the drug is injected, the air existing in the handle (1), the piston tube (9) and the check valve (15) is discharged to the air discharge hole (2), so that the drug forms bubbles in the check valve (15). The air discharge hole (2) by tightening the air discharge control (3) Thus chain.

As described above, while holding the handle (1) in the state filled with the drug while carrying the drug syringe while injecting the drug at the time of discovery.

In the state shown in FIG. 2 is a state in which the drug is filled and carried, in this case, the control opening 8 mounted above the upper cylinder 10a by the elastic force of the upper compression spring 13a is spaced apart from the upper cylinder 10a. The outer locking jaw 9a, which is the upper end of the lower large diameter tube portion 9 '' of the piston tube 9, is in close contact with the inner upper surface of the upper cylinder 10a by the lower compression spring 13b. In addition, the upper end of the guide tube 14 is in a state spaced apart from the inner locking jaw (9b), the hatch hole 20 is attached to the lower portion of the lower large diameter tube portion 9 "of the piston tube (9) needle 23 The end of is spaced apart from the inner short of the lower cylinder 10b with the raised portion 25 "of the needle bar 25 slightly raised.

Under the above conditions, when the Forester finds the 칡 and presses the handle 1 to insert the needle 25 into its root, the needle bar 25 is deeply embedded in the root by the pressing wall. At the same time as the 25 is pressed, the pressing force is applied to the piston tube 9 so that the upper and lower extrusion springs 13a and 13b have a compression action, so that the upper connector 7 and the adjuster 8 and the lower part are pressed. The hatch 20 attached to the lower end of the large diameter tube portion 9 '' has a lowering operation as shown in FIG. 3, and is inserted into the request 10 'between the upper and lower cylinders 10a and 10b. The shank valve 15 is fixed like the upper and lower cylinders 10a and 10b by the fixed positive protrusion 15 ', while the positive valve 15' is fixed by the incision groove 16. The extrusion valve hole 20 'inside the hatch 20, which is attached to the lower end of the lower large diameter pipe portion 9 ", which is lowered in operation, is closed to the extrusion ball valve 21. The suction valve hole 15 " and the lifting hole 20 of the check valve 15 are in a state of falling from the cap 18 in a long state, that is, a state widening between the suction valve hole 15 " Since the suction force acts on the space between the extruded valve holes 20 ', the suction ball valve 17 starts the opening operation by the suction force action, and the suction valve hole 15 " Drugs are injected and filled as much as the increased space between the extruded valve holes 20 ', and after the drug is completely filled, the solvent is removed by suction force, and the inside space above the extruded valve hole 20' Since the pressure of the injected and filled drug becomes the same, the suction ball valve 17 which has opened the suction valve hole 15 "closes the suction valve hole 15" by the spring 19. As shown in FIG.

After the Forest Service releases the pressure input applied to the handle 1 to pull out the needle bar 25, the upper and lower compression springs 13a and 13b, which were momentarily compressed, simultaneously act on the control mechanism 8 By raising the lower large diameter tube portion (9 ') and the piston tube body (9) is raised to the lower portion of the lower large diameter tube portion (9 "), the lifting hole 20 is also raised and lowered, as shown in FIG. Contrary to the pressure operation, the extrusion valve hole 20 'in the hatch 20 acts to narrow the space between the suction valve 15 "and the drug that has been injected and filled between the extrusion valve holes 20 ') Is ejected to the needle 23 through the extruded valve hole (20') while opening the extruded ball valve (21) and blows into the spout through the spout hole (25 ') of the needle bar (25). When the ejection action is completed, the extruded ball valve 21 closes the extruded valve hole 20 'by the spring 22. By preventing unnecessary leakage of the drug while at the same time waiting for the next ejection while the forest garden presses the handle (1) by only inserting the needle bar (25) into the root of the drug to eject.

On the other hand, since the ejection hole 25 "of the needle bar 25 is formed in the state which escaped from the tip part, when the needle bar 25 is inserted into the root | root, the case of the ejection chamber 25" is prevented. In addition, the injection needle 23 can be injected while the drug is inserted into the needle 25, thereby preventing the injection needle 23 from breaking.

In addition, the present invention as described above, the lowering operation side of the piston end (9) by adjusting the interval of the upper cylinder (10a) and the upper surface by adjusting the control mechanism (8) attached to the lower portion of the upper connector (7). It is possible to control the amount of ejection of the drug in one operation, so it is possible to reduce the excessive consumption of drugs during the decontamination work, which is a very practical design that can perform decontamination work more efficiently and effectively.
