Description

예초기의 칼날 보호구{A blade tool of grass cutter}A blade tool of grass cutter

본 발명은 예초기의 칼날 보호구에 관한 것이며, 예초기의 칼날 저부에 결합하여 예초할때 칼날 하부의 칼날 보호구가 지면에 닿게 하여 칼날이 지면의 돌과 부딪히지 않도록 예초작업을 할 수 있도록 하고, 고능률적인 예초작업이 이루어지게 한 것이다.The present invention relates to a blade protector of the mower, combined with the bottom of the mower so that the blade protector of the lower blade to the ground when mowing so that the blade does not collide with the stone on the ground, high efficiency The mowing work was done.

예초기는 축전지로 모터를 구동시키고, 모터의 회전축에 칼날을 결합하거나, 또는 가솔린으로 구동되는 경량 엔진의 동력을 케이블축으로 예초기 헤드의 회전축에 연결하고, 회전축에는 칼날을 구비하여 구성된다.The lawn mower is configured to drive a motor with a storage battery, couple the blade to the rotary shaft of the motor, or connect the power of a light-weight engine driven by gasoline to the rotary shaft of the mower head with a cable shaft, and the rotary shaft is provided with a blade.

이와 같은 예초기는 예초기의 회전되는 칼날을 농촌의 두렁에 성장하는 잡초를 예초하거나 또는 묘지에 성장하는 잡초를 예초하게 된다.Such a lawn mower will mow the weeds that grow in rural heads, or weeds that grow in graveyards.

이와 같은 예초기는 예초기 칼날 저부 중심의 축과 결합된 너트가 지면에 닿지 않도록 들고 작업하여야 하므로 노동력의 소모가 많아 예초에 많은 고통이 따르고, 특히 예초작업 과정에서 노출된 칼날이 지면의 돌이나 지면 바닥에 부딪혀 칼날이 부러지면 파편이 작업자에게 튀어 상해를 입게 되는등 안전사고가 잦은 결점이 있어 왔다.This mowing machine has to work with the nut combined with the shaft of the blade center of the mowing blade so as not to touch the ground, which causes a lot of labor and causes a lot of pain in the mowing, especially the blades exposed during the mowing process. When the blades are broken and the blades are broken, accidents have occurred frequently, such as debris splashing on workers and causing injury.

이를 해소하고자 예초기 헤드에 잡초를 가이드하고 지면에 칼날이 부딪히지 않도록 망을 구비하는등 여러가지 수단이 알려진바 있으나 작업과정에 장애가 되어 그 효과는 기대에 미치지 못하고 있다.In order to solve this problem, there are various known means such as guiding weeds on the mower head and providing a net so that the blades do not strike the ground, but the effect is not as expected due to obstacles in the working process.

또한 도1과 같이 예초기 헤드(a)의 회전축(b)에 칼날(c)과 캡(d)을 끼우고 너트(e)로 결합하여 캡(d)이 지면에 닿더라도 칼날(c)이 지면에 부딪히지 않도록 하게 되나, 동 캡(d)은 지면과 수직으로 닿게 되면 칼날(c)이 지면에 수평이되나 기울어지면 지면에 부딪히게 되는 요인이 되므로 이또한 안전이 보장되지 못하고 있다.In addition, as shown in Figure 1 by inserting the blade (c) and the cap (d) on the rotary shaft (b) of the lawn mower head (a) and combined with a nut (e), even if the cap (d) touches the ground, the blade (c) is grounded However, the cap (d) is in contact with the ground vertically, but the blade (c) is horizontal to the ground, but when tilted is a factor that will hit the ground, this also does not guarantee safety.

이에 본 발명은 종래의 제반결점을 해소하고 속이빈 하광상협의 함체의 벽면에는 장공을 구비한 칼날 보호구를 예초기 헤드의 회전축에 결합되는 칼날 저부에 칼날과 함께 결합하여 예초시에 칼날 보호구가 지면에 닿게 하여 고능률적으로 예초할 수 있도록 하고, 칼날이 지면에 부딪히지 않도록 하는 예초기의 칼날 보호구를 제공함에 목적이 있다.Therefore, the present invention solves the conventional defects, and the blade guard equipped with a long hole on the wall surface of the hollow Hagwangsang Hyeop combined with the blade at the bottom of the blade coupled to the rotary shaft of the lawnmower head blade at the time of mowing It is an object of the present invention to provide a blade protector of the lawn mower, which allows to mow more efficiently and to prevent the blade from hitting the ground.

본 발명은 도2 내지 도4와 같이 금속판재로 하광상협의 속이빈 함체(1)를 형성하고, 동 함체(1)의 상부면(2) 중심에는 축공(3)을, 원주면(4)에는 복수개의 장공(5)을 형성하여서 구성된다.2 to 4, the hollow housing 1 of the lower light cooperating body is formed of a metal plate as shown in FIGS. 2 to 4, the shaft hole 3 is formed at the center of the upper surface 2 of the housing 1, and the circumferential surface 4 is formed. It is formed by forming a plurality of long holes 5.

도면중 미설명부호 10은 예초기 헤드, 11은 회전축, 12는 가이드판, 13은 탄력부싱, 14는 나선부, 15는 너트, 16은 칼날을 표시한 것이다.In the drawings, reference numeral 10 denotes a mower head, 11 a rotating shaft, 12 a guide plate, 13 a resilient bushing, 14 a spiral part, 15 a nut, and 16 a blade.

이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

통상과 같은 예초기 헤드(10)의 회전축(11)에 칼날(16)과 본 발명의 함체(1)의 상부면(2)에 구비된 축공(3)을 끼우고, 함체(1)의 장공(5)으로 탄력부싱(13)을 회전축(11)에 끼우고 회전축(11)의 나선부(14)에 너트(15)로 체결하게 되면 도5와 같이 예초기의 칼날(16) 저부에는 함체(1)가 구비된다.Insert the blade 16 and the shaft hole (3) provided on the upper surface (2) of the housing (1) of the present invention to the rotary shaft (11) of the lawn mower head 10 as usual, the long hole of the housing ( 5) When the elastic bushing 13 is inserted into the rotating shaft 11 and fastened with the nut 15 to the spiral portion 14 of the rotating shaft 11 as shown in FIG. ) Is provided.

이와 같이 예초기의 칼날(16) 저부에 함체(1)가 결합되어 칼날(16)과 함체(1)는 함께 회전되며 예초기의 칼날(16) 하부에 위치하는 함체(1)를 지면에 닿게 하고, 예초기의 칼날(16)을 수평 또는 경사지게 하여 예초지점을 설정하여 작업하게 되면 작업자는 예초기에 함체(1)가 지면에 닿은 상태에서 예초작업이 이루어지게 되므로 노동력의 소모를 줄일수 있고, 작업을 고능률적으로 수행할 수 있게 된다.As described above, the housing 1 is coupled to the bottom of the blade 16 of the lawn mower so that the blade 16 and the enclosure 1 are rotated together to bring the enclosure 1 positioned below the blade 16 of the lawn mower to the ground, When the blade 16 of the lawn mower is set horizontally or inclined to work by setting the mowing point, the worker can mow the labor force because the mowing operation is carried out while the enclosure 1 is in contact with the ground during mowing, thus reducing the consumption of labor. It can be performed efficiently.

또 본 발명은 예초기의 칼날(16)을 지면에 근접되도록 경사지게 하여 예초작업을 할 수 있게 되고, 또 칼날을 수평으로 하여 예초작업을 하게 되므로 지면과 멀어진 지점에서 예초작업이 이루어지게 된다.In addition, the present invention is capable of mowing by inclining the blade 16 of the mower close to the ground, and the mowing operation is carried out at a point far from the ground because the mowing operation is also horizontal to the blade.

또 본 발명은 예초기 헤드(10)에 결합된 칼날(16)을 교체하거나 분리할때에는 함체(1)의 장공(5)으로 스패너등의 공구를 끼워 회전축(11)의 나선부(14)에 체결된 너트(15)를 풀면 분해되므로 칼날(16)등의 교체를 용이하게 할 수 있게 된다.In the present invention, when replacing or detaching the blade 16 coupled to the lawnmower head 10 is fastened to the spiral portion 14 of the rotary shaft 11 by inserting a tool such as a spanner with the long hole (5) of the housing (1) When the nut 15 is loosened, it is disassembled, so that the blade 16 can be easily replaced.

또 본 발명에서 함체(1)는 칼날(16)이 구비되는 상부는 폭이 좁고, 지면에 닿는 하부는 폭이 넓게 구성되므로 안정성이 있고, 예초작업에 장애 발생이 없어 사용이 편리하게 된다.In addition, in the present invention, the housing 1 has a narrow width at the upper end of which the blade 16 is provided, and the lower part contacting the ground has a wide width, so that the housing 1 is stable and there is no obstacle in the mowing operation, thereby making it convenient to use.

또 본 발명의 함체(1)의 원주면(4)에 복수개의 장공(5)은 칼날(16)과 함께 회전되면서 원심력이 형성되므로 장공(5)으로는 예취과정에서 전달된 잡초등의 유입은 발생되지 않게 된다.In addition, since the plurality of long holes 5 are formed on the circumferential surface 4 of the enclosure 1 of the present invention while the centrifugal force is formed while the blades 16 rotate together with the blades 16, the inflow of the weeds transmitted in the mowing process to the long holes 5 is It will not occur.

이와 같은 본 발명은 하광상협이고 속이빈 함체의 원주면에서 장공을 구비하여 예초기의 칼날 저부에 결합할 수 있도록 구성하여 이를 예초기 칼날 저부에 결합하여 사용하게 되면 예초기를 지면에 닿게하고 작업자가 예초기를 이동시키면서작업할수 있게 되므로 안전하고 예초작업이 고능률적이며 예초작업시 지면의 돌과 칼날이 부딪히는 현상을 줄일수 있게 되므로 안전하게 되는 것이다.The present invention is provided with a long hole in the circumferential surface of the Hagwangsanghyup and hollow housing to be coupled to the bottom of the blade of the lawn mower when used in combination with the blade of the lawn mower to bring the mowing machine to the ground and the worker mowing Since it is possible to work while moving, it is safe and mowing is highly efficient, and it is safe because it can reduce the collision of stones and blades on the ground during mowing.

따라서 이상과 같은 본 발명의 예초기의 칼날 보호구는 구조가 간단하여 제조가 용이하고, 예초작업시 칼날 보호구가 지면에 닿은 상태에서 예초작업을 할 수 있게 되므로 노동력의 소모를 줄이고 안전한 작업을 수행할 수 있게 되고 고능률적인 예초작업을 할 수 있게 되는 특징이 있다.Therefore, the blade protector of the lawn mower of the present invention as described above is easy to manufacture due to its simple structure, and the blade protector can be mowed while the blade protector is in contact with the ground during mowing, thus reducing the consumption of labor and performing safe work. It is characterized by being able to do high efficient mowing work.
