Embodiment 1

[0046] Such as figure 1 As shown, the coal seam drilling dust removal device provided in this embodiment includes: a drill pipe assembly 1 and an injection assembly 2, specifically:

[0047] The drill pipe assembly 1 is provided with a water spray hole 21 , the spray assembly 2 communicates with the drill pipe assembly 1 , and the spray assembly 2 is used for passing water and wind into the drill pipe assembly 1 .

[0048] Wherein, the water spray hole 21 can be one or more than two. Preferably, there are multiple water spray holes 21. This setting can make the spraying range larger and the dust removal effect better.

[0049] Further, the drill pipe assembly 1 may be provided with a water braided shaft 12 , and the injection assembly 2 may communicate with the drill pipe assembly 1 through the water braided shaft 12 .

[0050] The coal seam drilling dedusting device includes a drill pipe assembly 1 and a spray assembly 2. The drill pipe assembly 1 is provided with a water spra...

Embodiment 2

[0088] Such as figure 1 As shown, on the basis of the above embodiments, further, this embodiment provides a drilling rig, including a power mechanism and the coal seam drilling dust removal device in Embodiment 1, specifically:

[0089] The power mechanism is connected with the drill rod assembly 1 for driving the drill rod assembly 1 to rotate.

[0090] Wherein, the power mechanism may include a gyrator 13, a feeding device 14, a holder 15, and the like.

[0091] Further, the gyrator 13 can drive the drill pipe assembly 1 to rotate and guide the direction of the drill pipe assembly 1, and provide torque and rotation speed to realize angle change. The feeding device 14 can realize the feeding and pulling out of the drill pipe assembly 1 . The clamper 15 can complete the clamping of the drill pipe assembly 1 .

[0092] Further, the drilling rig may also include an air compressor. The air compressor communicates with the air connection pipe 4 and is used to provide pressure...

Abstract

The invention provides a coal seam drilling dedusting device and a drilling machine and relates to the technical field of coal seam drilling construction. The coal seam drilling dedusting device comprises a drill rod assembly and a spray assembly; a water spraying hole is formed in the drill rod assembly; and the spray assembly communicates with the drill rod assembly and is used for injecting water and air into the drill rod assembly, so that the technical problem that in the prior art, in the coal seam drilling construction process, the atomization space of a dedusting device cannot be omnidirectional, and thus the effect is poor is solved. The spray assembly injects the water and the air into the drill rod assembly, the water is sprayed out to be mist through the water spraying hole under the air pressure effect, and thus the dedusting effect is achieved. The water spraying hole is formed in the drill rod assembly, the atomization space can cover the whole interior of a drilled hole, therefore, the dedusting effect is better, the operation environment of a construction place is effectively improved, the probability of combustion explosion of coal dust is decreased, hole collapse accidents are effectively controlled, and the drilling success rate is increased; and meanwhile, the coal seam drilling dedusting device is small in size and weight and easy and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of coal seam drilling construction, in particular to a coal seam drilling dust removal device and a drilling rig. Background technique [0002] In the process of coal mine production, there are many hidden dangers of unsafe accidents. One of the practical difficulties faced in the underground coal mining operation at present is the problem of drilling into soft coal seams. During the construction process, there have been chain reactions such as borehole collapse, coal dust flying, and fire or explosion caused by gas exceeding the limit. [0003] In the current technology, dust collectors are generally used for drilling dust removal devices. The dust collector consists of three parts: the hole sealer, the connecting pipe, and the dust collector. The hole sealing device is mainly composed of a reaming drill bit, a reaming pipe, a tee, a sealing sleeve, and a chuck. The connecting pipe adopts the appropriat...
