Oriented dust-exhaust dust-fall cover of high pneumatic DTH (Down-The-Hole) drill

Abstract

The invention discloses an oriented dust-exhaust dust-fall cover of a high pneumatic DTH (Down-The-Hole) drill. The directional dust-exhaust dust-fall cover comprises a dust fall cover, a filter screen and a dust exhaust oriented plate; the dust-fall cover comprises left and right parts which are completely symmetric to each other, the upper part of the dust-fall cover is provided with an airtight piece, and a gridding hollow part is arranged all around the lower part of the dust-fall cover; the filer screen is arranged in the dust-fall cover, and the outer surface of the gridding hollow part covers the movable dust exhaust oriented plate; one sides of the left and right parts of the dust-fall cover are provided with a rotating shaft, the left and right parts are connected through the rotating shaft, and the other sides of the left and right parts of the dust-fall cover are provided with clamping bolts. According to the oriented dust-exhaust dust-fall cover provided by the invention, the effective control of the dust of the high pneumatic DTH drill can be realized, the strong anti-interference to wind can be realized, the dust diffusion can be realized, a worker can be prevented from sucking excessive dust, and the construction environment can be improved; the device is simple to operate, low in price and environmental-friendly in material, and is likely to be maintained, thereby being applicable to various drilling and construction environments, especially applicable to the operation of a windy wild drilling machine.

Description

Technical field [0001] The invention belongs to the field of blasting engineering, and specifically relates to a dust collector for a drilling rig, in particular to a directional dust discharge and dust reduction cover for a high-wind pressure DTH drilling rig. Background technique [0002] High-pressure down-the-hole drilling rigs will generate a lot of dust when they are working. These dust affect air quality and easily cause damage to the respiratory system of workers. Therefore, a dust reduction device is needed to settle the dust generated by the drilling. The existing dust collectors are expensive, bulky, and troublesome to maintain. Such sophisticated equipment is often not needed in the field environment. The harsh working environment in the field puts the staff in heavy dust and the distance between different types of workers is relatively long. This requires a simple dust-reducing and dust-removing device with low cost and convenient loading. Summary of the invention ...

Problems solved by technology

[0002] High wind pressure down-the-hole drilling rigs will generate a lot of dust during work. These dusts will affect the air quality and easily cause damage to the respiratory system of the staff. Therefore, a dust suppression and dust removal device is needed to settle the dust generated by drilling.

However, the existing dust collectors are expensive, bulky, and troublesome to maintain. Such sophisticated equipment is often not needed in the field environment, and the harsh working environment in the field makes the staff in serious floating dust, and the distance between different types of personnel is relatively long. This just needs a kind of low-cost, easy-to-load simple dust-reducing and dust-exhausting device
