Abstract

PURPOSE: A dust collecting grinder is provided to eliminate dust by forming a dust hole in a handle having a filter and an air vent, to manufacture easily without modifying the structure, and to prevent dust or contaminants from being dispersed during grinding. CONSTITUTION: A dust collecting grinder is composed of a body; a case(20) having a wheel cover(50) in the end of the body; a first bevel gear(12) rotating by a motor, and turning a second bevel gear(13) mounted in a shaft(14) and a grinding disk(40); an outer case(20a) having a dust collecting hole(21) in the front and both sides of the case; a fan(60) formed in the upper part of the shaft and placed over the dust collecting hole to suck dust; and a handle(30) having a filter(70). The dust is filtered with the filter, and air is discharged through an air vent(32) with penetrating the dust collecting hole through the handle. The handle is separated from the outer case with a threaded part(31). The dust is sucked into the dust collecting hole with the fan rotated in the shaft in rotating the grinding disk, and filtered with the filter. The air is discharged through the air vent of the handle.

Description

집진이 용이한 그라인더{A grinder}Dust collecting grinder {A grinder}

본 발명은 집진이 용이한 그라인더에 관한 것으로, 특히 종래 그라인더의 구조를 크게 변형하지 않으면서도 먼지의 흡입과 제거가 용이한 그라인더에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grinder that is easy to collect dust, and more particularly, to a grinder that is easy to suck and remove dust without significantly modifying the structure of a conventional grinder.

종래의 그라인더는 도 1내지 도 3에 도시한 바와 같이 모터에 의해 회전하는 연마디스크에 의해 물체의 표면을 다듬거나 갈아내는 작업을 하는 도구로, 매우 빠른 속도로 회전하면서 물체를 연마하게 되므로 연마작업 중에는 많은 분진이 발생하고, 상기 분진은 빠른 연마디스크의 회전에 비산되어지므로 작업자의 위생 및 환경에 매우 좋지 않은 영향을 미치게 된다.The conventional grinder is a tool for polishing or grinding the surface of an object by means of a polishing disk rotated by a motor as shown in FIGS. During the process, many dusts are generated, and the dusts are scattered to the rotation of the fast polishing disk, which has a very bad effect on the hygiene and the environment of the worker.

특히 조선소 등이 소재하고 있는 해안가는 선박의 도색작업을 위해 선박 표면에 묻어있는 오래된 페인트를 제거하는 작업을 그라인더로 하게 되는데, 이때 발생하는 엄청난 페인트가루에 의해 심각한 민원이 야기되고 있는 실정이다.In particular, the coastal area where shipyards are located is used to remove old paint on the surface of the ship for the painting work of the ship, which is causing serious complaints due to the enormous paint powder.

본 발명은 종래의 케이스 외부에 집진공이 형성되도록 외부케이스를 씌우고, 종래의 축의 상단에 팬을 형성하므로 써 연마디스크에 의해 발생한 분진이 연마디스크의 회전과 함께 축의 상단에서 회전하는 팬(fan)에 의해 그라인더 내부로 공기와 함께 흡입되도록 하되, 상기 분진만 필터에 의해 걸르고 공기는 손잡이를 관통하는 공기배출공을 통해 배출되도록 구성되어진 집진이 용이한 그라인더를 제공하기 위한 것이다.The present invention covers the outer case so that the dust collecting hole is formed on the outside of the conventional case, and the fan is formed on the upper end of the conventional shaft so that the dust generated by the polishing disk rotates at the top of the shaft with the rotation of the polishing disk. It is intended to provide an easy-to-collect dust grinder which is configured to be sucked together with the air into the grinder, but only the dust is filtered by the filter and the air is discharged through the air exhaust hole passing through the handle.

본 발명을 첨부한 도면에 의해 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

본 발명은 몸체(10)와, 상기 몸체(10)의 선단부에 형성된 휠커버(50)를 구비하는 케이스(20)와, 상기 몸체(10)에 내장된 모터(11)에 의해 케이스(20)에 돌설(突設)된 제 1베벨기어(12)를 회전시키고, 상기 제 1베벨기어(12)는 축(14)에 축착(軸着)된 제 2베벨기어(13)을 회전시켜 축(14)과 동시에 연마디스크(40)을 회전시키도록 구성된 공지의 그라인더에 있어서, 상기 케이스(20)의 외부에 전방과 양측면에 집진공(21)이 형성되도록 외부케이스(20a)를 형성하고, 상기 축(14)의 상단에는 팬(60)을 형성하되 상기 팬(60)이 집진공(21)의 상부에 위치하도록 함으로써 먼지를 흡입할 수 있도록 하고, 상기 집진공(21)은 다시 필터(70)를 구비하는 손잡이(30)와 관통되도록 함으로써 흡입된 먼지는 필터(70)에 걸러지고, 공기만 손잡이(30)에 형성된 공기배출구(32)를 통해 배출되도록 한 것이다.The present invention provides a case 20 having a body 10, a case 20 having a wheel cover 50 formed at a tip end of the body 10, and a motor 11 embedded in the body 10. The first bevel gear 12 is rotated, and the first bevel gear 12 is rotated by rotating the second bevel gear 13, which is fixed to the shaft 14, and the shaft 14 is rotated. In the known grinder configured to rotate the polishing disc 40 at the same time, the outer case 20a is formed so that dust collecting holes 21 are formed on the front and both sides of the case 20 outside the shaft 20, and the shaft A fan 60 is formed at an upper end of the 14, and the fan 60 is positioned above the dust collecting hole 21 so that dust can be sucked in. The dust collecting hole 21 is again a filter 70. The dust sucked by passing through the handle 30 having the filter is filtered by the filter 70, so that only air is discharged through the air outlet 32 formed in the handle 30. to be.

이때 외부케이스(20a)는 케이스(20)의 외부를 감싸는 상태로 몸체(10)에 결합되어지는 구조를 갖는다.At this time, the outer case 20a has a structure that is coupled to the body 10 in a state surrounding the outside of the case 20.

또한 상기 손잡이(30)는 필터(70)에 의해 걸러진 먼지를 제거할 수 있도록 나사부(31)에 의해 외부케이스(20a)와 착탈이 가능하도록 형성되어진다.In addition, the handle 30 is formed to be detachable from the outer case (20a) by the screw portion 31 to remove the dust filtered by the filter (70).

본 발명은 후방에만 휠커버(50)가 형성된 종래의 그라인더와 같은 구조에서도 팬(60)에 의해 연마디스크(40)의 주변의 공기를 흡입하므로 집진의 효과가 있으나, 이보다 더 집진 효과를 높이기 위해 종래 후방에만 형성되던 휠커버(50)의 전방에도 연마디스크(40)의 빈곳을 덮을 수 있도록 전방휠커버(51)를 형성하는 것이 바람직하다.The present invention has the effect of dust collection because the suction of the air around the polishing disk 40 by the fan 60 even in the same structure as the conventional grinder in which the wheel cover 50 is formed only at the rear, but in order to increase the dust collection effect than the conventional It is preferable to form the front wheel cover 51 so as to cover the space of the polishing disk 40 in front of the wheel cover 50, which is formed only at the rear side.

또한 디스크(40)에 다수개의 먼지흡입공(41)을 천공하므로 써 디스크(40)와 휠커버(50,51) 사이로만 흡입되던 먼지를 보다 직접적으로 흡입할 수 있도록 하였다.In addition, the plurality of dust suction holes 41 are drilled in the disk 40 so that the dust sucked only between the disk 40 and the wheel covers 50 and 51 can be sucked more directly.

이처럼 본 발명은 연마디스크(40)에 의해 발생한 분진이 연마디스크(40)의 회전과 함께 축(14)의 상단에서 회전하는 팬(60)에 의해 외부케이스(20a)와 케이스(20) 사이의 집진공(21)을 통해 공기와 함께 흡입되어지고, 상기 분진은 필터(70)에 걸러지고 공기만 손잡이(30)를 관통하는 공기배출공(32)을 통해 배출되어지는 것이다.As described above, according to the present invention, the dust generated by the abrasive disc 40 is rotated between the outer case 20a and the case 20 by the fan 60 which rotates at the upper end of the shaft 14 together with the rotation of the abrasive disc 40. The dust is sucked together with the air through the dust collecting hole 21, and the dust is filtered through the filter 70 and the air is discharged through the air discharge hole 32 passing through the handle 30 only.

이처럼 본 발명은 종래의 그라인더의 케이스에 외부케이스를 형성해 집진공을 형성하고, 상기 집진공의 상부에는 연마디스크를 회전시키기는데 사용하던 축을 이용하는 팬을 형성하되 상기 집진공은 필터와 공기배출구를 구비하는 손잡이와 관통되도록 함으로써 집진과 먼지의 제거를 용이하게 한 것이다.As described above, the present invention forms a dust collecting hole by forming an outer case in the case of a conventional grinder, and forms a fan using an axis used to rotate the polishing disk on the dust collecting device, and the dust collecting hole has a filter and an air outlet. By penetrating the handle to facilitate the removal of dust and dust.

또한 종래 그라인더의 구조를 크게 변형하지 않으므로 새로운 동력장치나 집진장치를 구성할 필요가 없어 제작이 용이하며, 연마작업시 발생되는 분진과 오염물질을 흡입하였다가 필터에 의해 걸렀다가 한꺼번에 제거할 수 있도록 함으로써 그라인더 사용시 발생되는 먼지나 기타 오염물질이 비산되는 것을 방지할 수 있는 효과를 갖는 것이다.In addition, since the structure of the conventional grinder is not greatly modified, there is no need to construct a new power unit or dust collector, so it is easy to manufacture, and it is possible to filter out dust and contaminants generated during polishing and filter them out at once. By doing so, the dust and other contaminants generated when using the grinder can be prevented from scattering.

이처럼 본 발명은 환경을 보호할 수 있고, 연마작업자의 분진흡입에 대한 직업병 발생우려를 현저하게 줄일 수 있는 매우 유용한 발명인 것이다.As described above, the present invention is a very useful invention that can protect the environment and can significantly reduce the occupational disease concern for dust inhalation of the polishing worker.
