Description
본 고안은 예초기용 칼날에 관한 것으로, 더욱 상세하게는 회전시 날이 펼쳐져 풀을 벨 수 있도록 하고, 날이 물체에 부딪칠시 접혀져 날의 부러짐을 방지함으로써, 작업자의 안전을 보장할 수 있도록 한 예초기용 칼날에 관한 것이다.The present invention relates to a blade for mowing, and more particularly, to allow the blade to be unfolded to cut the grass when rotating, and to prevent the blade from breaking when the blade hits an object, thereby ensuring the safety of the worker. It is about a mower blade.
일반적으로 예초기는 축전지로 모터를 구동시키고 모터의 회전축에 예초기용 칼날을 결합하거나, 또는 도 1에 도시된 바와 같이 가솔린으로 구동되는 경량 엔진의 동력을 케이블 축으로 예초기 헤드(1)의 회전축(2)에 연결하고 상기 회전축(2)에는 예초기용 칼날(3)이 결합되도록 구성된다.Generally, the lawn mower drives the motor with a battery and couples the blade for the mower to the rotary shaft of the motor, or as the cable shaft is driven by the power of a light-weight engine driven by gasoline as shown in FIG. ) Is connected to the rotary shaft (2) is configured to combine the blade 3 for the mower.
그러나 이와 같은 종래의 예초기는 농촌의 두렁에 성장하는 잡초를 베거나 또는 묘지에 성장하는 잡초를 제거하는 용도로 사용하는 것으로서, 예초(刈草)작업 과정에서 날이 지면의 돌이나 지면 바닥에 부딪혀 부러지면 부러진 날의 파편이 작업자에게 튀어 상해를 입는 등 안전사고가 잦은 문제점이 있었다.However, such a conventional mowing machine is used to cut weeds growing in rural headlands or to remove weeds growing in graveyards. In the mowing process, the blade is broken by a stone hitting the ground or the ground. Safety accidents were frequent, such as debris from broken blades on the ground and injuries to workers.
따라서, 본 고안은 상기와 같은 문제를 해결하기 위해 안출된 것으로, 본 고안의 목적은, 원판부의 저면에 위치해 있다가 회전시 원심력에 의해 날이 펼쳐져 예초작업을 수행하는 한편, 예초작업도중 날이 돌이나 지면에 부딪힐 경우 자연스럽게 접혀져 날의 부러짐을 방지함으로써 부러진 날의 파편이 작업자에게 튀어 상해를 입는 등의 안전사고를 원천적으로 방지할 수 있도록 한 예초기용 칼날을 제공함에 그 목적이 있다.Therefore, the present invention is devised to solve the above problems, the object of the present invention is located on the bottom surface of the disc portion, the blade is unfolded by centrifugal force during rotation to perform the mowing operation, while the blade during the mowing operation The object of the present invention is to provide a lawnmower blade that naturally prevents the blade from being broken by collapsing the stone or the ground to prevent the blade from being broken.
상기와 같은 기술적 과제를 해결하기 위해 본 고안은, 예초기 헤드의 회전축에 결합되는 예초기용 칼날에 있어서, 상기 회전축에 결합되는 체결공이 중앙에 형성된 원판부 저면에 다수개의 날을 방사상으로 설치하되 날의 일단을 원심력에 의해 펼쳐짐이 가능하도록 리벳으로 고정 설치함으로써, 날이 원판부 저면에 위치해 있다가 회전축의 회전시 원판부의 저면으로부터 날이 펼쳐져 풀을 베고, 날이 물체에 부딪칠시 접혀져 날의 파손을 방지함을 기술적 구성상의 특징으로 한다.In order to solve the above technical problem, the present invention, the blade for the lawn mower is coupled to the rotary shaft of the lawnmower head, a plurality of blades radially installed on the bottom of the disc portion formed in the center of the coupling hole coupled to the rotary shaft One end is fixed with rivets so that it can be unfolded by centrifugal force, so that the blade is located on the bottom of the disc, and the blade unfolds from the bottom of the disc during rotation of the rotating shaft to cut the grass, and when the blade hits an object, it is folded and broken. It is characterized by the technical configuration.
또한, 본 고안의 회전축의 저면에 설치되는 날은 3개 이상으로 설치됨을 특징으로 한다.In addition, the blade is installed on the bottom of the rotary shaft of the present invention is characterized in that the three or more installed.
도 2는 본 고안의 일실시예에 따른 사시도이고, 도 3은 본 고안의 일실시예에 따른 단면도이며, 도 4는 본 고안의 일실시예에 따른 저면사시도이고, 도 5는 본 고안의 일실시예에 따른 사용상태도를 각각 도시한 것으로서, 이하 첨부되는 도면을 참조하여 본 고안의 구성을 설명하면 다음과 같다.Figure 2 is a perspective view according to an embodiment of the present invention, Figure 3 is a cross-sectional view according to an embodiment of the present invention, Figure 4 is a bottom perspective view according to an embodiment of the present invention, Figure 5 is one of the present invention Referring to the state diagram of use according to the embodiment, with reference to the accompanying drawings, the configuration of the present invention as follows.
도 2 내지 4에 도시된 바와 같이 본 고안의 예초기용 칼날(3)은 예초기 헤드(1)의 회전축(2)에 설치되는 것으로서, 원판부(30)와 상기 원판부의 저면에 방사상(放射狀)으로 설치되는 다수개의 날(31)로 구성된다.As shown in FIGS. 2 to 4, the blade 3 for the lawn mower of the present invention is installed on the rotating shaft 2 of the lawn mower head 1, and the disc 30 and the bottom surface of the disc are radially radiated. It consists of a plurality of blades 31 are installed.
상기 원판부(30)는 원형의 판 형태로 중앙에는 상기 회전축(2)에 결합할 수 있도록 체결공(32)이 형성된다.The disc portion 30 is in the form of a circular plate fastening hole 32 is formed in the center to be coupled to the rotating shaft (2).
상기 원판부(30)는 예초기 헤드(1)의 회전축(2)에 끼워져 너트 등의 체결수단에 의해 체결된다.The disc portion 30 is fitted to the rotary shaft 2 of the lawnmower head 1 is fastened by a fastening means such as a nut.
상기 날(31)은 원판부(30)의 저면에 설치되는 것으로서, 수개가 방사상으로 설치되며 일단은 원심력에 의해 펼쳐짐이 가능하도록 리벳(33)에 의해 원판부(30)에 고정된다.The blade 31 is installed on the bottom surface of the disc portion 30, a number of radially installed and one end is fixed to the disc portion 30 by a rivet 33 to be unfolded by centrifugal force.
따라서, 날(31)은 원판부(30)의 저면에 접혀진 상태 즉, 원판부(30)의 원주 내에 위치해 있다가 회전축(2)이 회전되면 원심력에 의해 원판부(30)의 원주 밖으로 펼쳐져 예초작업을 수행한다.Therefore, the blade 31 is located in the folded state of the bottom of the disk portion 30, that is, located in the circumference of the disk portion 30, and when the rotating shaft 2 is rotated, it is spread out of the circumference of the disk portion 30 by centrifugal force to mow. Do the work.
이때, 상기 원판부(30) 저면에 설치되는 날(31)의 수는 3개 이상이 좋으며 예초작업시 가장 적합한 것은 3날 또는 4날로 구성하는 것이다.At this time, the number of the blades 31 installed on the bottom surface of the disc part 30 is good three or more, the most suitable for mowing work is to comprise three or four blades.
이상에서 상세히 살펴본 바와 같이, 본 고안의 예초기용 칼날(3)은 원판부(30) 저면에 설치된 날(31)이 원판부(30)의 외주연으로부터 출몰(出沒)식으로 펼쳐지거나 접혀지기 때문에 예초작업시 날(31)의 부러짐을 방지하여 작업자의 안전을 보장할 수 있도록 한 것으로서, 이하 첨부되는 도면을 참조하여 본 고안의 작용을 설명하면 다음과 같다.As described in detail above, the blade 3 for the lawn mower of the present invention is because the blade 31 installed on the bottom of the disc portion 30 is unfolded or folded from the outer periphery of the disc portion 30. In order to ensure the safety of the operator by preventing the broken blade 31 during the mowing operation, the operation of the present invention with reference to the accompanying drawings as follows.
도 5에 도시된 바와 같이, 예초기 헤드(1)의 회전축(2)이 회전되면 원판부(30)도 동시에 회전되면서 원판부(30)에 가려져 있던 날(31)이 물체가 원운동을 할 때 바깥쪽으로 쏠리는 힘 즉, 원심력(遠心力)에 의해 동시에 펼쳐지면서 예초작업을 수행한다.As shown in FIG. 5, when the rotary shaft 2 of the mower head 1 is rotated, the disc part 30 is also rotated at the same time while the blade 31 is covered by the disc part 30 in the circular motion. Mowing is carried out while being unfolded at the same time by the force that is pushed outward, that is, the centrifugal force.
이와 같이 날(31)이 펼쳐질 수 있은 것은 리벳(33)을 중심으로 날(31)의 회전이 자유롭기 때문이다.The blade 31 can be unfolded in this way because the rotation of the blade 31 around the rivet 33 is free.
한편, 예초작업도중 펼쳐진 날(31)이 지면의 돌이나 바닥에 부딪히면 날(31)이 리벳(33)을 중심으로 회전되면서 접혀지므로 날(31)의 파손을 방지할 수 있다.On the other hand, if the blade 31 unfolded during the mowing operation hit the stone or the ground of the ground, the blade 31 is folded while being rotated around the rivet 33 can prevent the damage of the blade 31.
따라서, 종래의 날(31)이 돌이나 지면에 부딪히면서 부러진 날(31)의 파편이 작업자에게 튀어 상해를 입는 것을 원천적으로 방지할 수 있다.Therefore, it is possible to prevent the fragments of the broken blade 31 from splashing on the worker while injuring the conventional blade 31 hit the stone or the ground.
이상에서 상세히 살펴본 바와 같이 본 고안의 예초기용 칼날은 원판부 저면의 날이 원심력에 의해 펼쳐져 예초작업을 수행하고, 날이 돌이나 지면에 닿을 경우 자연스럽게 접혀져 날의 파손을 방지하므로 예초작업을 수행하는 작업자의 안전을 보장할 수 있는 효과가 있다.As described in detail above, the blade for the lawn mower of the present invention is carried out by the centrifugal force of the blade of the bottom of the disc to perform mowing operation, and when the blade touches the stone or the ground, the blade is naturally folded to prevent the blade from breaking. There is an effect that can guarantee the safety of the worker.
