Description

TECHNICAL FIELD

[0001] The utility model relates to center drill technology field for gas pipeline drilling, specifically related to a center drill that can clean iron fillings. BACKGROUND

[0002] When the gas pipeline of the residential house is laid, the hole needs to be drilled on site for the installation of each branch, and the current method is to use a hole opener to drill a hole and then use a sweeper to clean the iron fillings in the pipeline. This method is prone to residual iron fillings after cleaning, which affects the subsequent plugging effect and the normal use of the clamping plate valve. Moreover, the drill bit used is usually integrally formed, which increases the maintenance cost in the later period. When the drill bit is damaged, it needs to be replaced as a whole, increasing the construction cost. SUMMARY

[0003] The utility model aims at providing a center drill that can clean iron fillings. The center drill can clean iron fillings simultaneously during drilling operation, reducing the cleaning work of iron fillings after operation, having good cleaning effect, being simple and convenient to operate, having high operation efficiency, and being highly practical.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] A center drill that can clean iron fillings comprises a drill rod main body, a clamping part fixedly arranged at one end of the drill rod main body, and a chip guide part fixedly arranged at the other end of the drill rod main body. A shovel drill blade is detachably arranged on the chip guide part. A plurality of magnet blocks are arranged on the circumference of the drill rod main body.

[0006] Preferably, a plurality of mounting surfaces are arranged on the circumference of the drill rod main body, and the magnet blocks are mounted on the mounting surfaces.

[0007] Preferably, the mounting surfaces are provided with three, four, or five mounting surfaces.

[0008] Preferably, two chip guide parts are arranged in a staggered manner, and the shovel drill blade is arranged between the two chip guide parts.

[0009] Preferably, the shovel drill blade and the chip guide part are fixedly connected by a pin or a bolt.

[0010] Preferably, a chip guide inclined surface is arranged on one side of the chip guide part, and the iron fillings generated during the operation of the shovel drill blade are discharged outward through the chip guide inclined surface.

[0011] Preferably, the chip guide part is protruded outward from the magnet blocks.

[0012] Preferably, a limiting column pin is arranged at the end of the drill rod main body, and a slot is arranged on the shovel drill blade. When the shovel drill blade is mounted on the drill rod main body, one end of the limiting column pin is located in the slot.

[0013] Preferably, the magnet block is made of a strong magnetic material.

[0014] The magnet block arranged in the circumferential direction of the drill rod body can attract iron filings during drilling operation, avoids the iron filings from entering the pipeline, avoids subsequent secondary cleaning of the pipeline, improves drilling operation efficiency, ensures the cleanliness of the pipeline, and has good cleaning effect. The chip guide part and the chip guide inclined surface can timely discharge the iron filings outward, facilitating drilling operation. The limiting pin can limit the position of the shovel drill blade, improve the convenience of installing the shovel drill blade, install the shovel drill blade between the two chip guide parts, and fix the shovel drill blade through the fastener, so that the shovel drill blade can be stably fixed and replaced, the operation is simple, and the subsequent maintenance cost is reduced. The drill rod body and the shovel drill blade are connected in a splicing manner, and the shovel drill blade can be replaced alone when the shovel drill blade is damaged, thereby reducing the cost.
