Description

Drilling hole dust falling device

Technical Field

The utility model belongs to the technical field of it is dustproof, specific theory relates to a drilling drill way dust device.

Background

Roadways tunneled under a mine are all tunneled in a soft rock stratum, and soft rock supporting becomes an important problem which puzzles construction. The soft rock has the characteristic of roadway deformation caused by easy expansion when meeting water, dry blasting is needed when a blast hole and an anchor rod (cable) hole are drilled, but the problems of high field dust concentration, low visibility, poor working environment, easy occupational hazard and the like exist in the dry blasting.

Therefore, it is necessary to provide a device which can ensure dry beating and reduce dust.

Disclosure of Invention

In order to overcome the problem that exists among the background art, the utility model provides a drilling drill way dust device can guarantee to beat futilely, and the dust spreads the working space when can effectively prevent to punch again.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

the drilling hole dust settling device comprises a dust collecting barrel, a dust collecting pipe and a drill rod; the drill rod is inserted into the dust collecting cylinder; the tail end of the dust collection cylinder is provided with a seal, and a drill rod channel for a drill rod to pass through is formed in the seal; the dust collection pipe is connected to the side edge of the dust collection barrel.

Preferably, the dust suction pipe is also provided with a water spray pipe and a high-pressure air pipe; the water spraying pipe and the high-pressure air pipe are respectively provided with a valve, and the outlet is respectively communicated with the dust collection pipe.

Preferably, the dust suction pipe is obliquely connected with the dust collection cylinder; and the outlets of the water spray pipe and the high-pressure air pipe are provided with nozzles facing the outlet direction of the dust suction pipe.

Preferably, the device further comprises a fixing plate; the center of the fixed plate is provided with a dust collecting cylinder connecting hole, and the periphery of the fixed plate is provided with a fixed hole; the head end of the dust collection barrel is connected with the fixing plate through the dust collection barrel connecting hole.

Preferably, a dust collecting device is connected to the tail end of the dust collecting pipe.

Preferably, the seal is made of rubber.

The utility model has the advantages that:

the high-pressure air pipe is arranged in the dust collection pipe, when the high-pressure air pipe sprays air, negative pressure is generated at the rear, dust generated during punching enters the dust collection pipe and is discharged from the dust collection pipe along with high-pressure air; through setting up the spray pipe, moisten the dust, discharge with dust granule or mud form, greatly reduced the dust volume of operation scene when punching.

Through the side with dust absorption union coupling at a dust collecting cylinder, can guarantee that the dust is discharged from the dust absorption pipe, does not influence the normal work of drilling rod again, realizes the dust fall when punching.

Through the field practice, the utility model discloses a dust absorption rate can reach more than 95%, greatly reduced the dust damage, improved mine visibility, created comfortable operational environment for the staff for the construction progress has improved tunnel visibility, ensures safe construction.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-3, the dust settling device for the drilling hole comprises a dust collecting barrel 1, a dust collecting pipe 2, a drill rod 3, a fixing plate 9 and a dust collecting device.

The dust collection tube 2 is obliquely connected with the dust collection tube 1 and is connected to the bottom of the dust collection tube 1, a spray tube 6 and a high-pressure air tube 7 are further arranged on the dust collection tube 2, and nozzles facing the outlet direction of the dust collection tube 2 are respectively arranged at outlets of the spray tube 6 and the high-pressure air tube 7. The dust collecting device is connected with the tail end of the dust collecting pipe 2 through a hose and is used for receiving the discharged dust.

When high-pressure air is sprayed out from the outlet of the high-pressure air pipe 7, negative pressure is generated behind the nozzle, dust generated in punching enters the dust suction pipe, and is discharged from the dust suction pipe 2 to the dust collection device along with the high-pressure air. The water mist sprayed out of the water spraying pipe 6 wets dust and is discharged in the form of dust particles or slurry, so that the dust amount of an operation site during drilling is greatly reduced, the dust falling rate can reach more than 95% through actual use, and the visibility during drilling of a mine is greatly improved.

The center of the fixed plate 9 is provided with a dust collecting cylinder connecting hole 10, and the periphery is provided with a fixed hole 11; the outer wall of the head end of the dust collection barrel 1 is connected with a fixing plate 9 through a dust collection barrel connecting hole 10, and the fixing plate 9 is fixed on a rock wall 12 by penetrating a fixing hole 11 through a bolt. The fixing plate 9 has both played the function of fixing the utility model on the rock wall 12, and the dust is leaked from the gap between the rock wall 12 and the dust collecting barrel 1.

The tail end of the dust collection cylinder 1 is provided with a flange plate used for being connected with a seal 4, the seal 4 is made of rubber, a drill rod channel 5 allowing a drill rod to freely pass through is arranged in the middle of the seal 4, bolt holes matched with the flange plate are formed in the periphery of the seal 4, and the drill rod 3 is inserted into the dust collection cylinder 1 to perform drilling operation. The seal 4 is made of rubber, so that hard collision between the drill rod 3 and the seal 4 during drilling can be avoided.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
