2. Description of the Related Art Conventionally, in a drilling machine for drilling wood holes, chips generated during drilling are suctioned by a dust collector. For this reason, the worktable is cleaned with an air gun or the like every time a cutting operation is performed. or,
When collecting chips only by the suction force of the dust collector, if the center of the suction port is not coaxial with the rotation axis of the drill due to the structure of the drilling machine, it will scatter radially from the drill rotation center. The suction force does not work evenly on the swarf that is produced, that is, the swarf scattered on the opposite side of the suction port requires a larger suction force than the swarf scattered near the suction port. For this reason, when viewed from the suction port side, it is not possible to suck the swarf scattered on the opposite side across the rotation axis of the drill. In order to suck this, it is necessary to increase the suction capacity of the dust collector.

As a dustproof device for a drilling machine, for example, as described in Japanese Utility Model Application Laid-Open No. 5-12059, a drill blade is attached to a body to be pierced and a drill blade is used. There has been proposed a structure in which a hole is drilled in a body to be drilled through a through hole provided in the hole.

[0004]

However, when the suction capacity of the dust collector is increased, there is a problem that the dust collector becomes large, power consumption increases, noise increases, and economic drilling work cannot be performed. In addition, if the suction port of the dust collector is installed on the side of the worktable, there is a problem in that the worktable on the opposite side of the suction port is difficult to collect swarf due to the arrangement.

The present invention has been made in view of the above problems, and has as its object to solve these problems, to efficiently collect chips, and to reduce the cost. It is an object of the present invention to provide a typical drilling machine dust collector.

According to a first aspect of the present invention, there is provided a dust collecting apparatus for a drilling machine, comprising: a drilling machine main body having a drill and an electric control unit; a work table on which a body to be pierced is placed; A dust collector having a suction port that opens at a position, and a drilling machine provided with an injection device provided at a position facing the suction port and capable of freely adjusting the injection angle, wherein compressed air is supplied from an injection nozzle of the injection device. The swarf on the work table is ejected and pushed into the suction port.

According to a second aspect of the present invention, in the dust collecting apparatus for a drilling machine, the injection of compressed air by the injection device can be operated in conjunction with a drill operation signal of an electric control unit of the drilling machine main body. is there.

[0008]

In the dust collecting apparatus for a drilling machine according to the first aspect, the compressed air is injected from the injection nozzle of the injection device to push the chips into the suction port. Chips can be efficiently pushed into the suction port. Further, since the suction force of the dust collector can be set low, the size of the dust collector can be reduced, and power consumption can be suppressed.

In the dust collecting apparatus for a drilling machine according to the second aspect, the injection of compressed air by the injection device can be operated in conjunction with the operation signal of the cutting drill of the electric control section of the drilling machine main body. Compressed air can be jetted only at the time of drilling work, and chips can be economically collected. Further, since cleaning is not required for each drilling operation, the time required for the drilling operation can be reduced.
