Description

과수용 속피 절단기{Fruit-tree cutter}Fruit tree cutting machine {Fruit-tree cutter}

본 발명은 과수의 속피를 절단하기 위한 절단기에 관한 것으로서, 좀 더 구체적으로는 힌지로 결합되는 좌우 한쌍의 칼날에 스프링의 탄성을 이용하여 과수의 속피를 일정부분만큼 절단하여 삼투압 현상을 일으키는 과수용 속피 절단기에 관한 것이다.The present invention relates to a cutting machine for cutting the inner skin of fruit trees, and more specifically, to a pair of left and right blades joined by hinges, using the elasticity of a spring to cut a certain portion of the inner skin of a fruit tree to cause an osmotic pressure phenomenon. It's about the skin cutting machine.

일반적으로 과일을 재배하는 농가, 과수원 등에서는 감나무, 포도나무 등의 과수를 재배하고 수확을 늘리기 위해서 삼투압 작용을 이용한 농법을 사용한다.In general, farmhouses and orchards that grow fruits use farming methods using osmotic pressure to grow fruit trees such as persimmon trees and vines and increase yields.

삼투압 작용을 이용한 농법은 과수의 줄기(가지) 어느 한 지점에서 속피를 절단하여 뿌리의 수액이 절단된 지점까지 상승시키고, 상승된 수액은 다시 줄기(가지)에 공급될 수 있도록 하여 과수의 수액 순환을 빠르게 하는 농법이다.The farming method using osmotic action cuts the inner bark at any point in the stem (branches) of the fruit tree, raises the sap of the root to the cut point, and allows the elevated sap to be supplied to the stem (branches) again, thereby circulating the sap of the fruit tree is a farming technique that speeds up

또한, 과일이 열리는 과수에는 과수의 수액을 영양원으로 하는 각종 벌레(해충)가 과수의 겉 껍질속에서 동면하는데, 벌레가 동면에서 깨기 전의 이른 봄에 삼투압 작용을 이용한 농법으로 과수의 성장과 과실의 생장을 빠르게 촉진시켜 수확을 서두름으로써 수확량은 늘리면서 벌레로 인한 재배의 손해를 미연에 방지한다.In addition, various insects (insects) that use the sap of the fruit tree as a nutrient source hibernate in the outer bark of the fruit tree in the fruit tree where the fruit is grown. By promoting rapid growth and hastening harvest, yield is increased while preventing damage to cultivation caused by insects.

이러한 삼투압 작용을 이용한 농법을 사용하기 위해서 대한민국 공개특허공보 제10-2013-0024541호;와 같이 가위와 같은 형태를 가지고 있어 과수의 속피를 절단하는 속피 절단용 가위가 제시되고 있다.In order to use the agricultural method using such an osmotic action, Korean Patent Laid-Open Publication No. 10-2013-0024541 has a scissors-like shape to cut the inner skin of fruit trees.

종래의 속피 절단용 가위는 힌지연결되어 있는 칼날이 과수의 겉 껍질을 물어냄과 동시에 물고 있는 칼날이 벌어지지 않도록 가위 손잡이를 손으로 잡고 있는 상태에서 어느 한방향으로 가위를 회전시킴과 동시에 적당한 힘을 가하여 속피를 절단시킨다.Conventional shear cutting shears bite off the outer rind of fruit trees with hinged blades and at the same time rotate the scissors in one direction while holding the handle of the scissors with your hand so that the biting blade does not open, and at the same time apply appropriate force It is applied to cut the inner skin.

그러나, 이러한 절단방법은 가해지는 힘이 과하면 과수의 가지가 완전히 절단되어 끊어질 수 있고 가해지는 힘이 약하면 겉 껍질을 올바르게 물지 못할뿐더러 속피가 올바르게 절단되지 못하였다.However, in this cutting method, if the applied force is excessive, the branches of the fruit tree may be completely cut and cut off, and if the applied force is weak, the outer skin may not be properly bitten and the inner skin may not be properly cut.

이러한 힘조절의 필요성으로 인해 초보자는 사용하기가 어렵고 작업전체의 시간이 늘어남에 따라 작업의 효율성이 떨어지는 문제가 있다.Due to the need for such force control, it is difficult for beginners to use it, and as the total work time increases, the work efficiency decreases.

특히, 두개의 손잡이를 한 손으로 잡고 가위를 회전시켜야 하기 때문에 회전각도가 원하는 만큼 나오지 않아 팔 전체 또는 발과 몸 전체를 움직여야 하는 관계로 작업자가 쉽게 피로를 느끼는 등 작업능률이 떨어지는 문제가 있다.In particular, since the scissors must be rotated while holding the two handles with one hand, the rotation angle does not come out as desired, so the entire arm or foot and the entire body must be moved, resulting in poor work efficiency such as easy fatigue.

대한민국 공개특허공보 제10-2013-0024541호;Republic of Korea Patent Publication No. 10-2013-0024541;

상기와 같은 문제점에 있어서, 과수의 속피가 완전히 절단되지 않을만큼 적당한 힘으로 겉 껍질과 속피를 물고 있어서 초보자도 쉽고 빠르게 사용할 수 있고, 작업자기 한 손으로 속피 절단기를 잡고, 과수의 속피 절단작업을 신속하고 능률적으로 할 수 있도록 구성된 과수용 속피 절단기를 제공하는 것을 목적으로 한다.In the above problem, since the outer skin and inner skin are bitten with an appropriate force so that the inner skin of the fruit tree is not completely cut, even beginners can use it easily and quickly, and the operator can hold the inner skin cutter with one hand and cut the inner skin of the fruit tree. It is an object of the present invention to provide a pericarp cutting machine for fruit trees configured to do so quickly and efficiently.

상기 목적을 달성하기 위한 본 발명의 과수용 속피 절단기는, 힌지에 의해 교차연결되는 두개의 칼날에 있어서 하나의 칼날에는 길이방향으로 소정의 길이를 가지는 손잡이가 형성되고 다른 하나의 칼날에는 과수가 들어오고 나갈 수 있도록 곡선부가 형성되며, 교차연결되어 있는 두개의 칼날 사이에는 스프링이 위치해 있어 스프링의 탄성력을 이용해 적당한 힘으로 과수의 가지를 물고 속피를 절단하도록 구성된다.In order to achieve the above object, the peel cutting machine for fruit trees of the present invention has two blades cross-connected by a hinge, wherein a handle having a predetermined length in the longitudinal direction is formed on one blade and the fruit tree is contained on the other blade. A curved part is formed so that it can come and go, and a spring is located between the two blades that are cross-connected, so that the elastic force of the spring is used to bite the branch of the fruit tree with an appropriate force and cut the inner skin.

또한, 교차연결되는 칼날의 내측에는 과수의 겉 껍질과 속피를 물기위한 톱날부와 톱날부로 물고 있는 겉 껍질과 속피를 절단하기 위한 칼날부가 구성된다.In addition, a saw blade part for biting the outer skin and inner skin of fruit trees and a blade part for cutting the outer skin and inner skin biting with the saw blade are formed inside the cross-connected blades.

본 발명의 과수용 속피 절단기는, 과수의 속피를 절단하는데 있어서 스프링의 탄성으로 인해 겉 껍질과 속피가 완전히 절단되지 않도록 물어냄과 동시에 삼투압 현상이 일어날 만큼만 속피를 부분절단하는 절단기를 제공할 수 있는 장점이 있다.In cutting the inner skin of a fruit tree, the inner skin cutting machine for fruit trees of the present invention bites so that the outer skin and inner skin are not completely cut due to the elasticity of the spring, and at the same time, it is possible to provide a cutter that partially cuts the inner skin only enough to generate an osmotic pressure phenomenon. There are advantages.

과수용 속피 절단기를 한 손으로 잡고 회전시키는 것으로 과수의 속피를 절단할 수 있기 때문에 초보자도 쉽게 사용할 수 있고, 작업시간을 단축시킴으로써 작업의 효율성이 뛰어나다는 장점이 있다.Since the peel cutting machine for fruit trees can be cut by holding and rotating it with one hand, even beginners can use it easily, and it has the advantage of excellent work efficiency by reducing working time.

제1 칼날(10)의 하단으로는 작업자가 한손으로 잡고 사용할 수 있게 길이방향으로 소정의 길이를 가지는 손잡이(12)가 형성되고 상단으로는 칼날(10,20)이 교차연결되었을 때 스프링(40)이 위치하는 고정부(11)가 형성된다.At the bottom of the first blade 10, a handle 12 having a predetermined length in the longitudinal direction is formed so that the operator can hold and use it with one hand, and at the top, when the blades 10 and 20 are cross-connected, the spring 40 ) The fixing part 11 is formed.

또한, 내측으로는 과수의 겉 껍질(A)과 속피(B)를 물어 고정시키기 위한 톱날부(31)와 겉 껍질(A)과 속피(B)를 절단하기 위한 칼날부(32)가 형성된다.In addition, on the inside, a saw blade part 31 for biting and fixing the outer rind (A) and inner rind (B) of the fruit tree and a blade part 32 for cutting the outer rind (A) and inner rind (B) are formed. .

제2 칼날(20)은 "S" 자형태로 상단은 제1 칼날(10)과 동일하게 고정부(21)가 형성되고 하단에는 과수와 접촉되어 열리고 닫혀 출입구의 역할을 하는 곡선부(22)가 형성된다.The second blade 20 has an "S" shape, the upper end is formed with a fixing portion 21 in the same manner as the first blade 10, and the lower end is in contact with the fruit tree to open and close the curved portion 22 serving as an entrance is formed

또한, 내측으로는 제1 칼날(10)과 동일하게 톱날부(31)와 칼날부(32)가 형성된다.In addition, the saw blade portion 31 and the blade portion 32 are formed in the same way as the first blade 10 on the inside.

상기 제1 칼날(10)과 제2 칼날(20)의 고정부(11,21) 사이에 위치하는 스프링(40)은, 코일스프링 또는 고정부(11,21)의 외측면에 'v'자형의 토션스프링(41)이 힌지(30)를 지나서 연결되게 설치한다.The spring 40 located between the fixing parts 11 and 21 of the first blade 10 and the second blade 20 has a 'v' shape on the outer surface of the coil spring or the fixing parts 11 and 21. The torsion spring 41 is installed to be connected through the hinge 30.

상기와 같이 구성된 본 발명의 작용을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above is as follows.

작업자가 속피(B)를 절단하고자 하는 과수의 뿌리 또는 가지에 절단기(1)를 밀어넣는다.A worker pushes the cutter 1 to the root or branch of a fruit tree to cut the inner bark B.

더욱 상세하게는, 절단기(1)의 곡선부(22)가 과수의 겉 껍질(A) 뒷쪽에 위치하는 상태에서 작업자가 손잡이(12)를 잡고 절단기(1)를 안쪽방향으로 잡아당긴다.More specifically, in a state where the curved portion 22 of the cutter 1 is located behind the outer husk A of the fruit tree, the operator holds the handle 12 and pulls the cutter 1 inward.

절단기(1)를 잡아당기게 되면 과수의 겉 껍질(A)에 맞닿아 있던 곡선부(22)가 벌어지게 됨과 동시에 고정부(11,21)에 위치한 스프링(40)이 늘어나게 되고 벌어지는 곡선부(22)로 과수가 절단기(1)의 내측으로 진입하게 되면서 칼날(10,20)이 과수의 외주면을 둘러 감싸는 형태가 된다.When the cutter (1) is pulled, the curved portion (22) that is in contact with the outer rind (A) of the fruit tree is spread, and at the same time, the spring (40) located at the fixing parts (11, 21) is stretched, and the curved portion (22) ), as the fruit tree enters the inside of the cutter 1, the blades 10 and 20 surround the outer circumferential surface of the fruit tree.

또한, 칼날(10,20) 사이로 과수가 완전히 들어오게 되면 고정부(11,21)에서 늘어나있던 스프링(40)이 다시 원래의 형태로 복구됨에 따라 벌어져있던 제1 칼날(10)도 줄어들어 과수를 물어 고정한다.In addition, when the fruit tree completely enters between the blades 10 and 20, the spring 40 stretched from the fixing parts 11 and 21 is restored to its original shape, and the first blade 10 that has been opened is also reduced to reduce the number of fruit trees. ask and fix

이때, 칼날(10,20)의 내측에 형성된 톱날부(31)가 겉 껍질(A)과 속피(B)를 뚫고 들어가 절단기(1)가 절단작업을 할 수 있게 고정시켜주고 칼날부(32)도 함께 파고들어가 과수의 겉 껍질(A)과 속피(B)를 절단가능한 상태로 만든다.At this time, the saw blade part 31 formed inside the blades 10 and 20 penetrates the outer skin A and the inner skin B to fix the cutter 1 so that it can cut, and the blade part 32 It also digs in together to make the outer skin (A) and the inner skin (B) of the fruit tree in a state that can be cut.

이렇게 제1 칼날(10)과 제2 칼날(20)이 과수를 물고 있는 상태에서 작업자는 손잡이(12)를 잡고 절단기(1)를 어느 한방향으로 180°가량 회전시키면 톱날부(31)와 칼날부(32)가 과수면의 외주면을 따라 회전하면서 과수를 절단하여 삼투압 현상을 일으킨다.When the first blade 10 and the second blade 20 bite the fruit tree in this way, the operator holds the handle 12 and rotates the cutter 1 by about 180° in either direction, thereby cutting the saw blade part 31 and the blade part (32) rotates along the outer circumferential surface of the fruit tree and cuts the fruit tree, causing an osmotic pressure phenomenon.

과수의 겉 껍질(A)과 속피(B)를 절단한 다음에는 절단기(1)에 과수를 진입시켰는 것과 반대로 작업자가 손잡이(12)를 잡고 절단기(1)를 바깥방향인 반대로 밀어내게 되면 곡선부(22)에 과수가 맞닿게 됨과 동시에 절단기(1)가 벌려지게 되어 절단된 과수가 이탈할 수 있게 된다.After cutting the outer skin (A) and inner skin (B) of the fruit tree, the operator holds the handle 12 and pushes the cutter 1 in the opposite direction to the opposite of entering the fruit tree into the cutter 1, the curved part As the fruit tree comes into contact with (22), the cutter (1) is opened at the same time, so that the cut fruit tree can escape.

이처럼 구성되는 절단기(1)는 작업자가 별도의 힘조절을 하지 않아도 스프링(40)이 지니고 있는 탄성을 이용해 과수가 완전히 절단되어 끊어지는 걱정없이 삼투압 현상을 일으킬 정도만큼 부분절단하여 초보자도 쉽게 작업이 가능하며 작업시간을 단축시킬 수 있어 작업의 효율성이 뛰어나다는 장점이 있다.The cutter (1) configured as described above uses the elasticity of the spring (40) without the operator having to adjust the force separately, so that the fruit tree is completely cut and cut in parts enough to cause an osmotic pressure phenomenon without worrying about being cut off, making it easy for beginners. It is possible to shorten the working time and has the advantage of excellent work efficiency.
