Description

유해 식물 고사제용 주입기{Tree killer injector}Injector for killing harmful plants {Tree killer injector}

본 발명은 유해 식물 고사제용 주입기로서, 더욱 상세하게는 칡, 아카시아 등 다른 식물의 성장이나 인간의 활동을 저해하는 유해한 식물에 못 형태의 주입기를 박아 넣어 편리하게 고사시킬 수 있는 고사제 주입기에 관한 것이다.The present invention relates to an injector for killing harmful plants, and more particularly, to an injector for killing harmful plants such as kudzu and acacia, which can be conveniently withered by inserting a nail-shaped injector into harmful plants that hinder the growth of other plants or human activities. will be.

덩굴 식물은 줄기가 곧게 자랄 수 없어 주변의 식물을 기둥삼아 감아 올라가는 형태로 생장하는 식물로 주변 식물의 수관을 덮어 주변 식물의 생장에 지장을 줄 뿐만 아니라 나무의 경제적 가치를 저하시킨다. 특히 칡은 번식력이 강하고 생장력이 왕성하여 어느 곳이나 침입하여 번무하기 때문에 조림지의 칡 제거는 조림의 성패와 직결된다.Climbing plants are plants whose stems cannot grow straight and grow in the form of winding up surrounding plants as pillars. They cover the crowns of surrounding plants, hindering the growth of surrounding plants and reducing the economic value of trees. In particular, since kudzu has strong fertility and vigorous growth, it invades anywhere and flourishes, so the removal of kudzu from reforestation is directly related to the success or failure of afforestation.

우리나라에서 5월에 흰색 꽃을 피우는 아카시아는 ‘아까시나무’의 잘못된 표현으로 메마른 땅에서 잘 자라며, 생장속도도 굉장히 빠른 특성이 있어 과거 황폐지 복구를 위해 사방지에 대량 조림되었다. 아까시나무는 자르면 자를수록 점점 더 번져 나가는 특성이 있고, 뿌리로 번식하는 모듈성(modularity)이 강해서 결코 죽어 사라지지 않는 생명체이다 보니 사오십년 만에 지상부의 식물체가 쓰러져도 땅속뿌리가 남아 있으면 다시 살아난다. 번식력이 강해 주변의 나무를 고사시키고 가시로 인해 인간의 활동을 저해한다.Acacia, which blooms white flowers in May in Korea, is an erroneous expression of 'black locust', grows well in dry land, and has a very fast growth rate, so it was planted in large quantities in erosion areas to restore desolated land in the past. The locust tree has the characteristic of spreading more and more the more it is cut, and it is a living organism that never dies because of its strong modularity in propagating by roots. Even if the above-ground plant collapses in 40 to 50 years, it will come back to life if the underground roots remain. Due to its strong fertility, it withers trees around it and hinders human activities with its thorns.

종래의 유해 식물 제거는 지상부 예취법, 주두부 제거법, 뿌리 굴취법 등의 물리적 방법과 글리포세이트 주입법, 반벨 도포법, 근사미 면봉처리법 등 약제를 사용한 화학적 방법이 있다. 물리적 방법이나 화학적 방법 모두 나무를 베거나 캐고 드릴로 구멍을 뚫는 노동력과 시간을 투여하여야 하므로 매년 많은 비용이 소요되고, 작업환경이 열악하여 제거되지 못한 잔류 뿌리 등으로 반복적인 노동력이 투여되는 등 효과적이지 못하였다.Conventional harmful plant removal includes physical methods such as aboveground part harvesting method, head head removal method, root excavation method, and chemical methods using drugs such as glyphosate injection method, banbell application method, and approximate rice cotton swab treatment method. Both the physical and chemical methods require labor and time to cut trees, dig, and drill holes, so they cost a lot every year, and are effective in repetitive labor for residual roots that could not be removed due to poor working conditions. I couldn't.

이하, 본 발명의 실시를 위한 구체적인 실시예와 도면을 참고하여 설명한다. 본 발명의 실시예는 하나의 발명을 설명하기 위한 것으로서 권리범위는 예시된 실시예에 한정되지 아니하고, 예시된 도면은 발명의 명확성을 위하여 핵심적인 내용만 확대 도시하고 부수적인 것을 생략하였으므로 도면에 한정하여 해석하여서는 아니 된다.Hereinafter, it will be described with reference to specific embodiments and drawings for the practice of the present invention. The embodiment of the present invention is for explaining one invention, and the scope of rights is not limited to the illustrated embodiment, and the illustrated drawings are limited to the drawings because only the essential contents are enlarged and the auxiliary parts are omitted for clarity of the invention. should not be interpreted as such.

도 1은 유해 식물 고사제용 주입기의 사시도로서, 수목의 줄기나 뿌리를 뚫고 들어가는 침부(10), 상기 침부와 연결되어 고사제 약액이 채워지는 액통부(20), 상기 액통부의 일측 하단에 형성되어 약액이 수목의 줄기나 뿌리에 침투되는 복수의 침투공(21), 앰풀이 끼워져 약액이 주입되는 주입구(23)를 포함한다.1 is a perspective view of an injector for killing harmful plants, including a needle 10 penetrating the stem or root of a tree, a liquid container 20 connected to the needle and filled with a deadly liquid, and formed at one lower end of the barrel. It includes a plurality of penetration holes 21 through which the chemical solution penetrates the stem or root of the tree, and an inlet 23 into which the ampoule is inserted to inject the chemical solution.

침부(10)는 망치로 액통부(20) 상단의 보강부(22)를 가격하면 수목의 줄기나 뿌리에 쉽게 파고들도록 뾰족한 원뿔형 금속으로 형성한다.The needle 10 is formed of a sharp conical metal so that it can easily penetrate the stem or root of a tree when the reinforcing part 22 at the top of the liquid tube 20 is hit with a hammer.

액통부(20)는 적정 고사량의 약액이 수용되는 원통으로 소정의 강도를 갖는 금속으로 형성한다.The liquid cylinder 20 is a cylinder in which an appropriate amount of chemical solution is accommodated, and is formed of metal having a predetermined strength.

액통부의 하단에는 약액이 수목의 줄기나 뿌리로 침투되도록 침투공이 복수로 형성된다. 실시예에서는 4개가 형성되었으나 이에 한정하지는 않는다.A plurality of penetration holes are formed at the lower end of the liquid tube so that the chemical solution penetrates into the stem or root of the tree. In the embodiment, four are formed, but it is not limited thereto.

침부의 갓부(11)는 액통부의 외경보다 크게 형성하여 박힐 때 침투공(21)이 막히지 않도록 한다.The cap 11 of the needle is formed to be larger than the outer diameter of the liquid cylinder so that the penetration hole 21 is not blocked when inserted.

액통부위 상단은 망치로 가격할 때 변형되지 않도록 액통부를 감싸 보강하는 보강부(22)를 형성한다.The upper end of the liquid barrel part forms a reinforcing part 22 that surrounds and reinforces the liquid barrel so that it is not deformed when hit with a hammer.

액통부의 주입구(23)는 앰풀의 투입구가 밀착되어 삽입될 수 있도록 내경을 형성한다.The inlet 23 of the liquid container part forms an inner diameter so that the inlet of the ampoule can be inserted in close contact with it.

고사제는 근사미, 터치다운 등 제초제 성분의 농약을 사용할 수 있다. As an withering agent, pesticides containing herbicides such as Geunsaemi and Touchdown can be used.

도 2는 본 발명에 따른 고사제 앰플의 정면도로서, 약액이 담긴 본체부(30), 주입기의 주입구에 삽입되는 투입구(31), 비틀거나 구부리는 힘으로 쉽게 부러지도록 투입구보다 가늘게 형성된 목부(32), 비틀거나 구부리는 힘으로 목부를 떼어내는 절단부(33)를 포함한다.Figure 2 is a front view of the antiseptic ampoule according to the present invention, the body portion 30 containing the medicinal solution, the inlet 31 inserted into the inlet of the injector, and the neck portion 32 formed thinner than the inlet so as to be easily broken by twisting or bending force ), and a cutting portion 33 that removes the neck portion by twisting or bending force.

앰풀은 투명한 유리나 합성수지로 형성할 수 있고 쉽게 부러지거나 잘려지는 가느다란 목부를 갖고 투입구를 주입기의 주입부에 끼워 본체부(30)에 있는 약액을 주입기의 액통부로 주입한다.The ampoule can be formed of transparent glass or synthetic resin, has a thin neck that is easily broken or cut, and inserts the inlet into the injection part of the injector to inject the liquid in the main body part 30 into the liquid passage part of the injector.

본체부의 약액은 액통부 용량보다 같거나 작게 하는 것이 넘치는 것을 방지할 수 있고 효과적으로 사용할 수 있다.When the liquid medicine of the main body is equal to or smaller than the capacity of the liquid container, overflowing can be prevented and can be effectively used.

도 3은 본 발명에 따른 고사제 주입기에 앰플을 끼운 실시예의 사시도로서, 주입기를 하방으로 경사지게 박으면 중력에 의하여 약액이 효과적으로 주입될 수 있다.Figure 3 is a perspective view of an embodiment in which an ampoule is inserted into an abrasive injector according to the present invention. When the injector is obliquely driven downward, the drug solution can be effectively injected by gravity.

도 4는 본 발명의 다른 실시예로 앰풀 주입구(23)를 넓혀 테이퍼 형태로 된 주입기의 정면도를 보여준다. 주입구를 앰풀 투입구와 꼭 맞게 하면 끼우는데 집중력을 요하기 때문에 연로한 농촌 인력이 작업함에 어려울 수 있다. 앰풀 주입구(23)를 침부의 갓부(11)보다 크게 하여 앰풀 투입구를 대충 끼워도 액통의 중간 정도에서 기밀성을 유지하면서 쉽게 삽입되어 연로한 농촌 인력도 편리하게 작업을 할 수 있다.Figure 4 shows a front view of a tapered injector by widening the ampoule inlet 23 according to another embodiment of the present invention. If the inlet fits snugly with the ampoule inlet, it can be difficult for elderly rural workers to work with because it requires concentration. By making the ampoule inlet 23 larger than the needle cap 11, even if the ampoule inlet is roughly inserted, it is easily inserted while maintaining airtightness in the middle of the liquid container, so that elderly rural workers can conveniently work.

약액 침투공(21)도 길이 방향으로 길쭉하게 형성하여 약액이 쉽게 수목의 줄기나 뿌리에 스며드는데 효과적이다.The chemical solution penetration hole 21 is also formed elongated in the longitudinal direction, so that the chemical solution is effective in easily permeating into the stem or root of the tree.

도 5는 본 발명의 다른 실시예로 고사제 앰플의 정면도로 약액이 담긴 본체부(30)를 주입기의 액통부(20)와 같이 투입구쪽이 좁아진 테이퍼 형태로 형성하면 주입기의 주입구에 쉽게 삽입하여 중간정도에서 밀접하여 기밀성을 확보할 수 있다. 절단부(33)는 가위로 자르거나 비틀어서 절단할 수 있다.5 is a front view of an antiseptic ampoule in another embodiment of the present invention. If the main body 30 containing the drug is formed in a tapered shape with a narrower inlet like the liquid container 20 of the injector, it is easily inserted into the inlet of the injector. Confidentiality can be secured by close to medium degree. The cut portion 33 may be cut with scissors or cut by twisting.
