Abstract

The present invention relates to a tool for preventing the rotation of a plate of a bush-cutting machine to prevent an elastic member from being damaged. The tool for preventing the rotation of a plate of a bush-cutting machine includes: an elastic member (120) disposed between a working platform and a blade-protecting plate; an impact buffer member (140) hooked onto the lower end of the elastic member and coupled to one side of the blade-protecting plate; and a cylindrical tube (110) surrounding the elastic member and the impact buffer member. A plate-coupling part (141) is disposed on the lower portion of the impact buffer member (140), and an elastic-member-coupling part (142) is disposed on the upper portion thereof. A cutting part (143) is disposed on one side of the intermediate portion between the plate-coupling part (141) and the elastic-member-coupling part (142). A hook (141a) protrudes from one side of the plate-coupling part (141) so as to hook onto the lower end of the cylindrical tube (110). According to the present invention, the hook may protrude from the side of the plate-coupling part so as to hook onto the lower end of the cylindrical tube. Thus, even though the parts are sold separately, a user will have no difficulty in terms of workability. Also, since the widths of the plate-coupling part and of the elastic-member-coupling part are equal to the inner diameter of the cylindrical tube, a gap does not occur between the impact buffer member and the cylindrical tube, thereby preventing the impact buffer member from being shaken within the cylindrical tube. Thus, the impact buffer member may have good durability. Also, the elastic member may be prevented from being separated by the cutting part of the impact buffer member.

Description

탄성부재 파손방지를 위한 예초기용 플레이트 회전방지구Mower plate rotation prevention device for preventing damage to elastic member

본 발명은 탄성부재 파손방지를 위한 예초기용 플레이트 회전방지구에 관한 것으로서, 좀더 상세하게 설명하면 예초기의 칼날을 보호하기 위해 칼날의 하부에 설치되는 보호 플레이트가 예초칼날의 회전에 의한 반작용으로 회전하는 것을 방지하는 회전방지구에 내장된 탄성부재의 잦은 파손을 방지하기 위한 플레이트 회전방지구에 관한 것이다.The present invention relates to a lawnmower plate rotation prevention device for preventing damage to the elastic member, in more detail to protect the blade of the lawnmower to protect the blade is installed in the lower portion of the blade rotates in reaction by the rotation of the mowing blade It relates to a plate anti-rotation device for preventing frequent breakage of the elastic member embedded in the anti-rotation device.

일반적으로 예초기는 잡초를 제거하거나, 성묘시 벌초 작업을 할 때 잡초를 적은 힘으로 많은 량을 제거하기 위한 장치로써, 예초기는 동력장치로 칼날을 회전시킴으로써 짧은 시간에 많은 면적의 잡초나 넝쿨들을 베어낼 수 있는 것이다.In general, the mower is a device for removing weeds or removing a large amount of weeds with a small force when working with weeds during the sacred grave. A mower cuts a large area of weeds or vines in a short time by rotating the blade with a power unit. I can make it.

그러나 칼날이 고속회전 하다 보니 돌과 같은 단단한 물체에 부딪힐 경우 고장은 물론 칼날 파편에 의해 작업자나 주위의 사람에게 부상을 입히기도 하는 등의 단점을 갖는다. 따라서 칼날 하부에 칼날을 보호하기 위한 칼날보호플레이트를 덧댐으로써 칼날을 보호하고자 하고 있으나 상기 칼날보호플레이트가 예초칼날의 회전에 의한 반작용에 의해 회전되어 원하는 목적을 달성하기 곤란한 단점을 갖는다.However, as the blade rotates at a high speed, it hits a hard object such as a stone and has a disadvantage such as a failure as well as injury to an operator or people around by blade fragments. Therefore, to protect the blade by adding a blade protection plate for protecting the blade in the lower blade, but the blade protection plate is rotated by the reaction by the rotation of the mowing blade has a disadvantage that it is difficult to achieve the desired purpose.

따라서 본 발명자는 특허출원 제10-2010-0056800호를 선출원한 바 있으나, 이는 예초기용 플레이트 회전방지구(1)의 스프링부재(2) 양단에는 충격완충부재(4)가 걸려서 설치되도록 하되, 상기 충격완충부재(4)의 하단에는 링(ring)형상의 결합부(6)가 형성되도록 하고, 상단에는 걸이부(3)가 형성되도록 하며, 상기 결합부(6)와 걸이부(3) 사이에는 절개부가 형성되도록 하였다.Therefore, the present inventors have filed a patent application No. 10-2010-0056800, but this is to be installed by hanging the shock-absorbing member (4) on both ends of the spring member (2) of the lawn mower plate rotation prevention device (1), At the lower end of the shock absorbing member 4, a ring-shaped coupling part 6 is formed, and at the upper end, a hook part 3 is formed, between the coupling part 6 and the hook part 3. Incision was made to form.

이로 인해 충격완충부재를 가장 반복적이고 지속적인 충격이 가해지는 위치에 배치하여 탄성부재의 파손을 방지할 수 있도록 하였다.As a result, the shock absorbing member is placed in a position where the most repetitive and continuous impact is applied to prevent the breakage of the elastic member.

그런데 상기한 플레이트 회전방지구는 충격완충부재(4)의 하단에 형성된 결합부(6)의 크기가 스프링부재를 감싸고 있는 원통관의 직경보다도 작은 것이어서 충격완충부재(4)를 스프링부재의 하단에 끼우고 상기 스프링부재의 상단을 작업봉의 결합구에 걸려고 할 때 상기 충격완충부재(4)가 원통관 속을 통과하여 올라와 다음 작업이 곤란한 단점을 갖는다.However, the plate rotation preventing device is smaller than the diameter of the cylindrical tube surrounding the spring member of the coupling portion 6 formed on the lower end of the shock absorbing member 4, so that the shock absorbing member 4 is inserted into the lower end of the spring member. When the upper end of the spring member is caught by the coupling hole of the working rod, the shock absorbing member 4 rises through the inside of the cylindrical tube and has a disadvantage in that the next operation is difficult.

그렇다면 상기 충격완충부재(4)의 결합부(6)를 칼날보호플레이트(5)에 걸고 스프링부재를 잡아당겨 스프링부재의 상단을 작업봉의 결합구에 걸어야 하는데, 이는 각각의 부품을 분리하여 판매하는 당업계의 특성상 매우 불합리한 일이 아닐 수 없다.Then, the engaging portion 6 of the shock absorbing member 4 should be hooked to the blade protection plate 5 and the spring member should be pulled to hook the upper end of the spring member to the engaging hole of the working rod, which separates and sells each component. It is very unreasonable in the nature of the art.

또한 상기 충격완충부재(4)의 상단에 형성되는 걸이부(3)는 원통관의 직경보다도 현저히 작은 것이어서 예초작업시 진동 및 충격에 의해 원통관 내에서 많은 유격공간으로 인해 많이 흔들리게 되고 이로 인해 피로도가 커져 내구성이 현저히 낮아지게 된다.In addition, the hook portion (3) formed on the top of the shock absorbing member 4 is significantly smaller than the diameter of the cylindrical tube is shaken a lot due to the large clearance space in the cylindrical tube due to vibration and impact during the mowing operation The fatigue increases, and the durability is significantly lowered.

더구나 심한 충격이 가해질 경우 탄성부재가 충격완충부재(4)의 절개부를 통해 이탈되기도 하는 등의 단점을 갖는다.Moreover, when a severe shock is applied, the elastic member may be separated through the cutout of the shock absorbing member 4.

상기와 같은 목적을 달성하기 위하여 본 발명은 작업대와 칼날보호플레이트 사이에 설치되는 탄성부재와, 상기 탄성부재의 하단에 걸려 칼날보호플레이트의 일측에 결합되는 충격완충부재와, 상기 탄성부재와 충격완충부재를 감싸는 원통관으로 이루어지는 탄성부재 파손방지를 위한 예초기용 플레이트 회전방지구에 있어서, 상기 충격완충부재는 하부는 플레이트결합부가 형성되고 상부에는 탄성부재결합부가 형성되도록 하되 상기 플레이트결합부와 탄성부재결합부 사이 일측 중간에는 절개부가 형성되도록 하고 플레이트결합부의 일측에는 걸림턱이 돌출되도록 하여 원통관의 하단에 걸리도록 구성되는 탄성부재 파손방지를 위한 예초기용 플레이트 회전방지구를 제공하고자 함을 목적으로 한다.In order to achieve the above object, the present invention is an elastic member that is installed between the workbench and the blade protection plate, and the shock absorbing member coupled to one side of the blade protection plate hanging on the lower end of the elastic member, the elastic member and the impact buffer In the lawnmower plate rotation prevention device for preventing damage to the elastic member made of a cylindrical tube surrounding the member, the impact buffer member is formed so that the lower portion of the plate coupling portion and the upper portion of the elastic member coupling portion, the plate coupling portion and the elastic member The purpose of the present invention is to provide a cutting device for rotating the plate for preventing the breakage of the elastic member configured to be caught on the lower end of the cylindrical tube by forming a cutout portion at one side between the coupling portions and a locking jaw protruding at one side of the plate coupling portion. do.

상술한 바와 같이 본 발명은 플레이트결합부의 일측에는 걸림턱이 돌출되도록 하여 원통관의 하단에 걸리게 되어 각각의 부품을 분리하여 판매하여도 작업성에 지장이 없는 효과를 갖는다.As described above, the present invention has the effect that there is no problem in the workability even if each part is sold separately to be caught on the lower end of the cylindrical tube so that the locking jaw protrudes on one side of the plate coupling portion.

또 본 발명은 플레이트결합부와 탄성부재결합부의 너비가 원통관의 내측 직경과 동일하게 형성됨으로써 충격완충부재와 원통관 사이에 유격공간이 거의 없어 충격완충부재가 원통관 내에서 흔들리지 않게 되고 이로 인해 충격완충부재의 내구성이 양호해지는 효과를 갖는다.In addition, in the present invention, since the width of the plate coupling portion and the elastic member coupling portion is formed to be the same as the inner diameter of the cylindrical tube, there is almost no clearance space between the shock buffer member and the cylindrical tube so that the shock buffer member is not shaken in the cylindrical tube. It has the effect that the durability of the shock absorbing member becomes good.

또한 본 발명은 탄성부재가 충격완충부재의 절개부를 통해 이탈되는 현상을 원천봉쇄할 수 있는 매우 유용한 발명이다.In addition, the present invention is a very useful invention that can block the phenomenon that the elastic member is separated through the incision of the shock absorbing member.

이에 본 발명의 구성을 첨부된 도면에 의하여 당업자가 용이하게 이해하고 재현할 수 있도록 상세하게 설명하면 다음과 같다.Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

본 발명은 작업대와 칼날보호플레이트 사이에 설치되는 탄성부재(120)와, 상기 탄성부재의 하단에 걸려 칼날보호플레이트의 일측에 결합되는 충격완충부재(140)와, 상기 탄성부재와 충격완충부재를 감싸는 원통관(110)으로 이루어지는 탄성부재 파손방지를 위한 예초기용 플레이트 회전방지구에 있어서, 상기 충격완충부재(140)는 하부는 플레이트결합부(141)가 형성되고 상부에는 탄성부재결합부(142)가 형성되도록 하되 상기 플레이트결합부(141)와 탄성부재결합부(142) 사이 일측 중간에는 절개부(143)가 형성되도록 하고 플레이트결합부(141)의 일측에는 걸림턱(141a)이 돌출되도록 하여 원통관(110)의 하단에 걸리도록 구성된다.The present invention is an elastic member 120 is installed between the workbench and the blade protection plate, the shock absorbing member 140 is coupled to one side of the blade protection plate hanging on the lower end of the elastic member, the elastic member and the impact buffer member In the anti-rotator plate rotation prevention device for preventing damage to the elastic member made of a cylindrical tube 110, the impact buffer member 140 is formed with a lower portion of the plate coupling portion 141 and the upper portion of the elastic member coupling portion 142 ) Is formed, but the cutout portion 143 is formed in the middle of one side between the plate coupling portion 141 and the elastic member coupling portion 142 and the locking jaw 141a protrudes on one side of the plate coupling portion 141. It is configured to be caught on the lower end of the cylindrical tube (110).

또한 본 발명은 상기 플레이트결합부(141)와 탄성부재결합부(142)의 너비는 원통관(110)의 내측 직경과 동일하거나 거의 동일하게 형성되도록 구성됨이 바람직하다. 이는 플레이트결합부와 탄성부재결합부의 너비가 원통관의 내측 직경과 동일하게 형성됨으로써 충격완충부재(140)와 원통관(110) 사이에 유격공간이 거의 없게 되고, 이로 인해 충격완충부재(140)가 원통관(110) 내에서 흔들리지 않게 되기 때문이다.In addition, the present invention is preferably configured such that the width of the plate coupling portion 141 and the elastic member coupling portion 142 is formed to be the same or almost the same as the inner diameter of the cylindrical tube (110). This is because the width of the plate coupling portion and the elastic member coupling portion is formed equal to the inner diameter of the cylindrical tube there is almost no clearance space between the shock buffer member 140 and the cylindrical tube 110, thereby the shock buffer member 140 This is because the cylindrical tube 110 is not shaken.

따라서 충격완충부재(140)의 내구성이 양호해지고, 탄성부재(120)가 충격완충부재(140)의 절개부(143)를 통해 이탈되는 현상을 막을 수 있다.Therefore, durability of the shock absorbing member 140 may be improved, and the elastic member 120 may be prevented from being separated through the cutout 143 of the shock absorbing member 140.

상기 플레이트결합부(141)와 탄성부재결합부(142)는 탄성부재(120)와 칼날보호플레이트(150)에 걸기 쉽게 걸고리 형상을 갖는 것이 바람직하다.The plate coupling portion 141 and the elastic member coupling portion 142 preferably has a hook shape to be easily hooked to the elastic member 120 and the blade protection plate 150.

또한 상기 충격완충부재(140)에는 탄성부재(120)와 칼날보호플레이트(150)에 걸기 쉽게 플레이트결합부(141)와 탄성부재결합부(142) 일측 양단이 서로 절개, 즉 이격되어야 한다. 이렇게 형성된 절개부(143)에 의해 칼날보호플레이트와 탄성부재(120)에 충격완충부재(140)를 걸어서 결합할 수 있는 것이다.In addition, both ends of the plate coupling portion 141 and one side of the elastic member coupling portion 142 may be incised, spaced apart from each other, so that the impact buffer member 140 may be easily hooked to the elastic member 120 and the blade protection plate 150. The impact protection member 140 is coupled to the blade protection plate and the elastic member 120 by the cutout portion 143 formed as described above.

또한 상기 충격완충부재(140)는 충격에 강한 강철재질로 제조함으로써 반복적이고 지속적인 충격이 가해지더라도 잘 견딜 수 있으며, 따라서 상기 충격완충부재(140)에 탄성만 제공하는 탄성부재(120)는 진동 및 충격에 아무런 영향을 받지 않게 되어 내구성이 강해진다.In addition, the shock absorbing member 140 is made of a steel material that is strong against impact, so that the shock-absorbing member 140 can withstand even repeated and sustained impacts. Thus, the elastic member 120 providing only the elasticity to the shock buffer 140 is vibration and It is not affected by the impact, which makes it more durable.

따라서 탄성부재(120)는 상기 충격완충부재(140) 사이에서 탄성만을 제공하게 되고 충격완충부재(140)가 모든 충격을 흡수하게 되어 탄성부재(120)가 파손되는 것을 방지하여 예초기의 고장을 최소화할 수 있게 된다.Therefore, the elastic member 120 provides only elasticity between the impact buffer member 140 and the shock buffer member 140 absorbs all the shocks to prevent the elastic member 120 from being damaged, thereby minimizing the failure of the lawn mower. You can do it.

상기 탄성부재(120)는 스프링이 가장 바람직하나, 고무줄 및 탄성이 있는 재질이라면 어떤 것이라도 무방하다.The elastic member 120 is most preferably a spring, any material as long as the elastic material and elastic material.

이처럼 상기한 구성을 갖는 본 발명이 비록 한정된 실시예에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능하다 할 것이다.Although the present invention having the above-described configuration has been described by means of a limited embodiment, the present invention is not limited by this and the technical spirit of the present invention and the following by those skilled in the art to which the present invention pertains. Various modifications and variations will be possible within the scope of the appended claims.
