Abstract
본 고안은 예취기용 칼날을 개량하여 안전하게 구성한 것으로 보다 구체적인 것은, 금속제로 된 예취기날칼(1)의 상면에 합성수지로 성형된 안전판(2)을 씌우고 안전한 상면에 상면칼날을 부착할 수 있게 하여서 칼날이 파손될 때, 파편이 외주로 튀는 것을 방지하고 덩굴이 칼날 상면에 감기는 것을 방지할 수 있게 한 예취기용 안전 칼날이다.The present invention is a safe construction by improving the blade for the mower, and more specifically, to the upper surface of the mowing blade (1) made of metal put a safety plate (2) formed of synthetic resin and to attach the upper blade to the safe upper surface When broken, it is a mowing safety blade that prevents debris from splashing outward and prevents the vines from winding onto the blade top.
Description
본 고안은 예취기용 칼날을 개량하여 파손시 파편이 발생되지 않도록 안전하게 구성한 것으로 보다 구체적인 것은 직4각형상의 금속판으로 제작되어 중심부에 부착구멍이 형성되고 좌우측 칼날판의 측면을 따라 칼날이 형성되는 예취기칼날에 있어서, 예취기칼날의 상면에 합성수지제 안전판을 덧씌워서 되는 것을 특징으로 한다.The present invention is designed to secure the cutting machine blade so that no debris is generated when broken. More specifically, the cutting blade is formed of a rectangular metal plate, the attachment hole is formed in the center and the blade is formed along the side of the left and right blade plate In the above, characterized in that the upper surface of the mowing blade is covered with a synthetic safety plate.
이를 위해 본 고안은 예취기칼날의 상면에 피복되며 피복된 덮개 상면에 덮개 상면에서 직각으로 돌출되게 2∼3개의 상면칼날이 더 장치될 수 있게 상면 칼날 고정부를 형성시킨 합성수지제 안전판을 특징으로 한다.
To this end, the present invention is characterized by a safety plate made of a synthetic resin, which is formed on the upper surface of the cutting blade and formed on the upper surface of the coated cover so that two or three upper blades can be mounted at right angles from the upper surface of the cover. .
통상적으로 예취기칼날은 칼날판이 얇은 금속판으로 제조되어 작업대 하단에 부착하고 회전시켜서 풀을 베도록 되어 있으므로 사용중에 돌이나 큰나무뿌리와 같은 강한 물체에 부디치면 칼날이 파손되어 파편이 발생하고 칼날의 회전이 높기 때문에 파편이 튀어나와 인체에 닿으면 치명적인 사고가 발생하는 문제가 있고, 덩굴이 우거진 곳에 예취용 칼날을 투입하여 예초할 때는 칼날상면으로 풀이 감기게 되고 그 양이 많아지면 칼날 회전을 방해하여 고장의 원인이 되게 하는 불편이 있었기 때문에 이를 방지하기 위한 방법으로 금속제 칼날판의 둘레에 탄성체의 합성수지를 피복시켜서 칼날판체와 결합시키는 방법으로 파편 발생이 방지되게 한(실용신안등록제 20-0282478호) 것이 개발된바 있고, 공개실용신안공보 20-1998-0006131호가 공지되어 있다.
Generally, cutting blades are made of thin metal plates and are attached to the bottom of the workbench and rotated to cut the grass, so if you touch them on a strong object such as a stone or a big tree root during use, the blades are broken and fragments are generated. Because of this high debris protrudes and touches the human body there is a problem that fatal accidents occur, put mowing blades in the vines when mowing the grass is wound on the upper surface of the blade and when the amount is large, the blade rotation is interrupted In order to prevent this, there was an inconvenience to cause a breakdown, and the synthetic resin of the elastic body was coated around the metal blade plate to prevent the occurrence of debris by combining with the blade plate body (Utility Model Registration No. 20-0282478). And JP 20-1998-0006131 is known.
본 고안은 종래의 불편을 해소하기 위하여 개발된 것이다.
The present invention has been developed to solve the conventional inconvenience.
본 고안은 금속제로 된 예취기날칼(1)의 상면에 합성수지로 성형된 안전판(2)을 씌우고 안전한 상면에 상면칼날을 부착할 수 있게 하여서 칼날이 파손될 때, 파편이 외주로 튀는 것을 방지하고 덩굴이 칼날 상면에 감기는 것을 방지할 수 있게 한 것이다.
The present invention is to put the safety plate (2) formed of a synthetic resin on the upper surface of the metal cutting blade (1) made of metal and to attach the upper blade to the safe upper surface to prevent the fragments from splashing outwards when the blade is broken, and the vines It is to prevent the wound on the upper surface of the blade.
이와 같이 된 본 고안은 금속제 예취기칼날(1) 상면에 합성수지제 안전판(2)이 피복되어 예취기 칼날상면에 밀착하고 주변을 감싸기 때문에 예취기칼날이 파손될 경우 파편이 외주로 튀는 것을 예방할 수 있고, 안전판(2)은 예취기칼날과 분해 결합이 되므로 예취기칼날을 뒤집어 사용할 때도 결합시켜서 사용할 수 있으며, 안전판(2) 상면에 상면칼날(3)이 장치되어 예취기칼날위로 지나가는 덩굴을 절단하므로 예취기 칼날위에 덩굴이 감기는 것을 방지할 수 있게 되는바, 안전하면서 성능이 좋은 예취기칼날을 구성할 수 있는 이점이 있고, 상면칼날(3)은 그 삽입부에서 삽탈할 수 있으므로 교환하기 쉽고 그 형상은 하단이 넓고 상단이 좁은 사다리꼴 형상으로 되어서 칼날삽입홈(2c) 형상과 대응하므로 삽입홈에 삽입되면 예취기칼날이 회전하여 원심력이 작용되어도 외부로 튀어나갈 염려가 없게 되는 안전성이 있다.
The present invention is made of a synthetic resin safety plate (2) is coated on the upper surface of the metal mowing machine blade (1) close to the top surface of the mowing machine and wraps around, so that when the mowing machine blade is broken, the debris can be splashed outwards, and the safety plate ( 2) is decomposed and combined with the mowing blade, so it can be used even when the mowing blade is turned upside down, and the upper blade (3) is installed on the safety plate (2) to cut the vines passing through the cutting blade so that the vine is wound on the mowing blade. It is possible to prevent the bar, it has the advantage of constructing a safe and good mowing blade, the upper blade (3) can be removed from the insertion part, so it is easy to replace the shape is wide bottom and top As it becomes narrow trapezoidal shape and corresponds to the blade insertion groove (2c) shape, when it is inserted into the insertion groove, the mowing machine blade rotates and the centrifugal force There are safety concerns which eliminates the out of operation even if the protruding to the outside.
