粉塵は排除できない。The dry-type core drill has the advantage that it can be used anywhere and its use range is not restricted because it does not require a water supply facility and does not require water treatment measures. One of the problems with such a method is a countermeasure against dust generated during drilling. JP 5
In the device disclosed in JP-A-8-49207, air in the core bit is sucked by a vacuum suction device to air-cool the diamond chip and to eliminate dust in the hole. However, dust in the core bit can be eliminated. However, dust outside the core bit cannot be eliminated.

In some cases, the dust around the core bit is surrounded by a dust collecting pad, and the dust inside and outside the core bit is removed by suction using a vacuum suction device connected to the dust collecting pad.However, the dust collecting pad surrounding the core bit affects the rotation of the core bit. A gap is provided to prevent dust from leaking, and dust easily leaks from this gap.

An object of the present invention is to provide a dry type dust collecting pad for a core drill which can prevent dust from leaking at the time of drilling and can reduce or eliminate noise due to metal noise generated at the time of drilling.

続されないようになっている。FIG. 2 shows an example in which a core drill of a handy type is used. A dust collecting pad 15 is made of metal, and a fitting insertion hole 16 into which a core bit 14 is loosely fitted is provided at the center of the bottom. A ring-shaped seal 18 made of sponge is mounted in the recess.
The lower part of the inner circumference has a small diameter, and is tightly sealed around the entire circumference of the core bit 14 so that dust in the dust collecting pad does not leak out. In the figure, reference numeral 19 denotes a connection port so that the dust collection bag 20 is not connected.

Thereby, the tip of the core bit is cooled, and the chips are blown out. Then, the dust is sequentially discharged from the dust collecting pad to the dust collecting cloth bag 20 and does not escape upward by the seal 18.
