예취기 칼날{The brush cutter knife} Brush cutter knife {The brush cutter knife}

본 고안은 예취기의 칼날에 관한 것으로 다양한 칼날에 있어 상하 마주 설치되는 판 형태의 칼날을 상호 반대 방향으로 회전시키거나 일측의 칼날을 회전시킴으로 날의 교차에 의해 풀이나, 잡초의 절단이 이루어질 수 있도록 하는 예취기의 칼날 에 관한 것이다.
The present invention relates to a blade of a mowing machine so that cutting of grass or weeds can be made by intersecting the blades by rotating the blades in the form of plates installed in various blades in opposite directions or by rotating the blades on one side. It is about the blade of the mower.

기존의 상하 칼날을 이용하는 예초기 칼날의 형태는 도1에 도시된 바와 같이 통상 부채꼴형의 타원 또는 원형으로 구성하여 상하에 겹쳐 상기 상하부 칼날(10,10‘)의 일측을 중심으로 상호 엇갈리게 원호운동을 시키거나 일측의 칼날을 회전시켜 피절삭물을 절단하도록 구성되며 절삭에 직접적인 역할을 하는 돌출절삭부(100)가 돌출 구성된다. 상기 돌출절삭부(100)는 통상 끝이 갈수록 좁아지는 형상인 사라리꼴 형상으로 돌출되어지는 것이 일반적 사항이다. As shown in FIG. 1, the shape of the existing mower blade using the existing upper and lower blades is generally formed in an ellipse or a circular fan shape and overlaps the upper and lower blades (10, 10 ') with each other in a circular motion. It is configured to cut or to cut the workpiece by rotating the blade of one side and the protrusion cutting portion 100 that plays a direct role in the cutting is configured to project. The protrusion cutting unit 100 is generally protruded in a Sarari shape, the shape is narrower toward the end.

본 고안은 이러한 칼날(10,10‘)의 돌출절삭부(100)의 구성은 피절삭물이 완전히 돌출부 내부로 인입되지 않고 돌출절삭부(100)의 입구에서 맞물릴 경우 튐현상이 발생하고, 절삭 시 피절삭물이 외부로 밀려나가는 현상이 다수 발생하여 절삭력이 떨어지는 경우가 많았다. 특히 돌출부의 절삭면이 조금만 무뎌져도 피 절삭물이 쉽게 칼날 밖으로 밀려가는 현상이 다수 발생하였다. 또한 절삭을 위해 칼날을 움직일 때 고정된 칼날에 저항이 많이 발생하는 문제점이 있어 이를 해결하고자하는 것에 주안점을 두고 그 기술적 과제로서 고안한 것이다. The present invention is a configuration of the protrusion cutting portion 100 of the blade (10, 10 ') is a phenomenon occurs when the workpiece is engaged in the inlet of the protrusion cutting portion 100 is not completely drawn into the protrusion, When cutting, a large number of phenomena in which the workpieces are pushed to the outside occurred, and the cutting force was often decreased. In particular, even if the cutting surface of the protrusion is slightly blunt, the workpieces are easily pushed out of the blade. In addition, there is a problem that a lot of resistance is generated in the fixed blade when moving the blade for cutting was devised as a technical problem with a focus on solving this problem.

상기한 과제를 달성하기 위한 본 고안에 따르면 이에 칼날이 돌출절삭부(100)를 구성함에 있어 피절삭물이 외부로 밀리어 나가지 않도록 상기 돌출절삭부(100)에 구성되는 절삭면(110)을 오목형 또는 파형으로 구성하고, 튐 현상을 억제하기 위하여 양측의 칼날 중 일측의 칼날을 보다 길게 구성하고, 상기 길게 구성된 칼날의 돌출절삭부(100)들을 회전방향 측의 절삭면 끝부를 얇게 구성하여 맞닿을 시 마찰력을 최소화함으로 과제를 해결하고자 하였다. According to the present invention for achieving the above object, the cutting surface 110 is configured in the protruded cutting unit 100 so that the cutting blade is not pushed out in the configuration of the protruding cutting unit 100 to this end. Concave or corrugated, and in order to suppress the 튐 phenomenon to configure the blade on one side of the blade on both sides longer, and the protruding cutting portion 100 of the long configured blade to form a thin end of the cutting surface in the rotational direction The aim was to solve the problem by minimizing the friction force at the contact.

본 고안을 통하여 피절삭물의 밀림현상을 방지하여 절삭력을 높이고, 단단한 물체에 부딪쳐 튐 현상이 발생하는 것을 최소화 할 수 있을 뿐 만 아니라, 절삭 시 저항을 최소화 할 수 있게 되어 사용상 편의성 효율성, 안정성을 높일 수 있는 그 효과가 큰 고안이라 하겠다. Through this design, it is possible to prevent cutting of the workpiece and increase cutting force, and to minimize the occurrence of spalling when hitting a hard object, as well as to minimize the resistance during cutting, thereby improving convenience, efficiency and stability. It can be said that the effect is a great design.

이하 첨부된 도면1 내지 13을 참고하여 본 고안의 구성 및 작용을 보다 상세하게 설명히 설명하면,
앞서 살펴 바와 같은 부채꼴형상의 상하 칼날을 구성하여 고정된 중심으로 원호운동을 하여 피절삭물을 절삭하게 구성되는 칼날 구성은 도 1에 도시된 바와 같이 칼날(10,10‘)의 외측으로는 돌출절삭부(100)가 구성되어 있는데 상기 돌출절삭부는 통상 사다리꼴형상으로 일정간격으로 돌출구성되어 있으며 원호운동의 회전방향인 양측면과 끝부로 절삭면(110)이 구성되어 상하부 칼날이 엇갈리게 회전하면서 피절삭물을 절삭하게 되는 것이다. 절삭시 상하부 칼날을 동시에 엇갈리게 구동할 수 있고, 일측의 칼날은 고정되고 타측의 칼날만 구동시킴으로 구동할 수 있는 것이다. 이때 도 3에 도시된 바와 같이 원호운동하지 않는 일측의 칼날(10)을 운동하는 칼날(10’) 보다 길게 구성하여 단단한 재질의 방해물과 접촉을 미리 감지하여 회전되는 칼날이 방해물에 닿지 않도록 함으로서 튐 현상을 미연에 방지할 수 있는 것이다. 통상 하부칼날이 고정되고 상부 칼날이 구동되는 것이 일반적이다. 또는 양측이 모두 구동하는 칼날에 있어서도 일측을 길게 하여 구성하면 단단한 재질의 방해물과 접촉하는 힘이 약해 상대적으로 튐 현상을 줄일 수도 있다.

또한 종래의 칼날(10,10‘)의 돌출절삭부(100)의 도2에서 도시된 바와 같이 피절삭물(c)이 밀리어 나가는 현상이 발생한다. 특히 절삭면(110)이 조금만 무뎌지면 이러한 현상은 도드라지게 나타나며 따라서 절삭력이 대폭 감쇄되는 문제점이 발생한다.

따라서 도 4내지 6에 도시된 바와 같이 상기 돌출절삭부을 구성함에 있어 상부 또는 하부칼날 중 하나는 사다리꼴형상으로 종래와 같이 돌출되어 구성되더라도 타측의 칼날의 돌출절삭부(100)의 양측 절삭면(110)을 오목형태로 구성하여 피절삭물(c)이 외부로 밀리어 나가는 것을 억제할 수 있다. 즉, 돌출절삭부(100) 중간지점의 지름은 짧게 구성하고 일정 길이만 큼은 양측으로 갈수록 지름이 커지도록 구성하면 절삭면(110)이 오목형상으로 구성되어 피절삭물이 돌출절삭부(100)에 의해 단속되어 이탈되지 않게 되는 것이다
또한 다른 실시예로서 도 7내지 9에 도시된 바와 같이 피절삭물의 단속력을 좀더 높게 하기 위하여 양측 칼날(100)의 돌출절삭부(110)를 공히 상기와 같이 중간지점의 지름이 짧고 양측으로 갈수록 지름이 커지도록 하여 절삭면(110) 양측이 오목형상으로 구성할 수도 있는 것이다.
또한 도 10내지 11에 도시 된 바와 같이 단속력을 높이기 위한 다른 한 구조로서 상하부 칼날 중 일측 또는 양측 칼날 돌출절삭부(100)의 절삭면들을 물결모양과 같은 파형(p)으로 형성하여 피절삭물을 단속하면서도 곡선으로 미끄러지며 잘릴 수 있도록 구성할 수도 있는 것이다.
또한 칼날의 다른 실시예로서 도 12내지 13에서와 같이 상기와 같은 구조를 하면서도 절삭을 위해 칼날을 이동 시 따른 물체들과의 접촉 시 발생하는 저항을 최소화하기 위하여 양측의 칼날의 중앙을 기준으로 좌측에 구성된 돌출절삭부(100)는 좌측면 끝부를 보다 얇게 날을 세워 날세움부(t)하고, 중앙을 기준으로 우측에 구성된 돌출절삭부(100)는 우측면 끝부를 보다 얇게 날을 세운 날세움부(t)를 구성함으로서 칼날의 이동 시 마찰력을 최소화 할 수 있는 것이다.
상기와 같은 구성들에 있어 사용자에 따라서 상기의 언급된 칼날(10,10‘)의 돌출절삭부(100)의 형태를 선택적으로 조합하여 다양한 기능을 가지는 형태로 조합하여 사용이 가능한 것이다. Hereinafter, with reference to the accompanying drawings 1 to 13 will be described in more detail the configuration and operation of the present invention,
As shown in FIG. 1, the blade configuration configured to cut the workpiece by circular arc motion by forming a fan-shaped upper and lower blades as described above and cutting the workpiece is fixed to the outside of the blades 10 and 10 '. The cutting part 100 is configured, but the protruding cutting part is formed in a trapezoidal shape at regular intervals, and the cutting surface 110 is composed of both sides and ends in the direction of rotation of the circular arc motion so that the upper and lower blades rotate alternately. Cutting water. When cutting, the upper and lower blades can be driven in a staggered manner at the same time, the blade of one side is fixed and can be driven by driving only the blade of the other side. In this case, as shown in FIG. 3, the blade 10 on one side that does not move circularly is configured longer than the blade 10 'for moving, thereby detecting the contact with a hard material in advance and preventing the rotating blade from touching the obstacle. The phenomenon can be prevented beforehand. Usually, the lower blade is fixed and the upper blade is driven. Alternatively, even if the blades are driven by both sides, if one side is made long, the force of contact with the obstacle of a hard material is weak, so that the spalling phenomenon may be relatively reduced.

In addition, as shown in FIG. 2 of the protruding cutting part 100 of the conventional blades 10 and 10 ', a phenomenon in which the cut object c is pushed out occurs. In particular, if the cutting surface 110 is slightly blunt, this phenomenon appears to be sluggish, so that the cutting force is greatly reduced.

Therefore, as shown in FIGS. 4 to 6, even when one of the upper or lower blades is formed in a trapezoidal shape as projected in the prior art as shown in FIGS. 4 to 6, both cutting surfaces 110 of the protruding cutting portion 100 of the other side blade are formed. ) Can be formed in a concave shape to suppress the work piece c to be pushed outward. That is, if the diameter of the intermediate point of the protruding cutting part 100 is configured to be short and the diameter is increased toward both sides as long as a predetermined length is formed, the cutting surface 110 is formed in a concave shape so that the workpiece is the protruding cutting part 100. Is cracked down by)
In addition, as shown in FIGS. 7 to 9 as another embodiment, the diameters of the intermediate points are shorter as both sides of the protruding and cutting parts 110 of both blades 100 are increased in order to increase the intermittent force of the workpiece. Both sides of the cutting surface 110 may be formed in a concave shape by increasing the diameter.
In addition, as shown in Figures 10 to 11 as another structure for increasing the intermittent force cutting surface of one or both of the blade protruding cutting portion 100 of the upper and lower blades by forming a wave-like wave shape (p) You can also configure it so that it can be cut and slipped in a curve while intermittent.
In addition, as another embodiment of the blade as shown in Figs. 12 to 13 while the structure as described above while the left side with respect to the center of the blades on both sides in order to minimize the resistance generated in contact with the objects when moving the blade for cutting Protruding cutting portion 100 is configured in the blade edge to make the blade thinner than the left end portion (t), and the protrusion cutting portion 100 configured on the right side relative to the center of the blade edge is set thinner than the right edge By configuring the part (t) it is possible to minimize the friction force during the movement of the blade.
In the above configurations, depending on the user, it is possible to selectively combine the shapes of the protruding and cutting parts 100 of the above-mentioned blades 10 and 10 'to be used in combination with various shapes.
