Description

A drill rod for drilling dust collector

technical field

The utility model relates to the technical field of drill pipe equipment, in particular to a drill pipe for a drilling dust collector.

Background technique

During the drilling process of decoration and decoration, a lot of dust will be generated, which will not only affect the environment, but also cause harm to the body if workers inhale too much dust for a long time. In order to solve the above problems, it is necessary to design a dust collector that cooperates with the drilling rig to collect the dust generated by the drilling in a centralized manner to avoid causing dust. However, the existing drill pipe cannot be used with the dust collector, and when in use , the connection between the drill pipe and the dust collector can not be well dustproof.

Utility model content

The purpose of the utility model is to provide a drill rod for a drilling dust collector, so as to solve the technical problem that the drill rod cannot be well matched with the dust collector in the prior art.

The utility model provides a drill rod for a drilling dust collector, which comprises a connecting part, an extension part and a drill head. The drill head and the connecting part are arranged at both ends of the extension part and three are integrally formed; For the slot connected to the drilling rig, the maximum outer diameter of the drill head is equal to or smaller than the diameter of the extension part, the front end of the connection part is truncated, and the diameter of the extension part is equal to or smaller than the minimum diameter of the front end of the connection part, The extension part is provided with a dustproof sheet.

Further, the drill head includes an impact head and an impact rod, and the outer diameter of the impact head is larger than the outer diameter of the impact rod.

Compared with the prior art, the beneficial effects of the present utility model are:

First, the utility model adds an extension part in the middle of the drill pipe, and the extension part is used to make the drill pipe penetrate through the dust collector, so that the dust collector can cooperate well. The diameter of the extension is increased, and since the drill rod is overall longer, the overall hardness of the extension can be increased by increasing the thickness of the extension.

Second, the dust-proof sheet arranged in the middle of the drill pipe and the front end of the connecting part in the shape of a truncated cone can play a certain dust-proof role at the connection between the drill pipe and the dust collector.

Thirdly, in the second embodiment, the outer diameter of the impact head is larger than the outer diameter of the impact rod, so that the drill head will not be clamped by the wall when drilling, so that the drill head can be easily pulled out of the punched hole.

Embodiment 1, as shown in FIG. 1 to FIG. 3 below, the embodiment of the present utility model provides a drill rod for a drilling dust collector, including a connecting part 1, an extension part 2 and a drill part 3, the drill part 3 and The connecting portion 1 is provided at both ends of the extension portion 2 and three are integrally formed. The connecting portion 1 is provided with a slot 4 for connecting with a drilling machine. The maximum outer diameter of the drilling portion 3 is equal to or smaller than the diameter of the extension portion 2. ; This arrangement increases the diameter of the extension part 2 relative to the ordinary drill pipe. Since the drill pipe is overall longer, the overall hardness of the extension part 2 can be increased by increasing the thickness of the extension part 2. The front end of the connecting part 1 In the shape of a circular cone, the diameter of the extension part 2 is equal to or smaller than the minimum diameter of the front end of the connection part 1, and the extension part 2 is provided with a dustproof sheet 5; wherein, the dustproof sheet 5 and the drill pipe can be welded by welding , screw connection and gluing, etc., use welding and gluing to fix firmly, but it is difficult to disassemble and replace, using screw connection, easy to replace, so that the utility model can be replaced when the utility model is applied to dust collectors of different sizes. Dust flakes 5, to ensure dustproof effect.

Specifically, the drill head 3 includes an impact head 31 and an impact rod 32, and the outer diameter of the impact head 31 is larger than the outer diameter of the impact rod 32; such an arrangement makes the drill head 3 not be affected by the wall when drilling. Clamping facilitates the extraction of the drill head 3 from the drilled hole, and this arrangement facilitates processing and purchase of suitable drill rods.
