Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as figure 1 , figure 2 , image 3 As shown, the air drilling and drilling dust removal equipment of the present invention includes a dust collector 6 and a dust collector 11. The dust collector 6 is provided with a streamlined tee 1, and the tail of the streamlined tee 1 is connected to the dust collector 11. Inside the dust collector 6 It is equipped with a dynamic sealing device and a static sealing device. The dynamic sealing device includes at least two layers of movable baffles sleeved on the drill pipe 7. The movable baffle is a ring-shaped piece with an aperture larger than the diameter of the drill pipe 7. The two layers of movable baffles Respectively the first movable catch 4 and the second movable catch 5, the first movable catch 4 and the second movable catch 5 are arranged at the afterbody of the drill rod 7 in turn, the first movable catch ...

Abstract

The invention provides pneumatic drill pore-forming and drilling dedusting equipment, which solves the problem that the conventional dust collection device is poor in airtightness effect, and includes a dust remover and a dust collector, wherein a streamline tee joint is arranged on the dust remover; the dust collector is connected with the tail of the streamline tee joint; a dynamic seal device and a static seal device are arranged in the dust remover; the dynamic seal device includes two layers of movable separation blades arranged on a drill rod in a sleeving manner; the movable separation blades are circular ring pieces with the pore diameter larger than the diameter of the drill rod; and the static seal device is arranged at the tail of the dust remover and can absorb dust. The equipment adopts the streamline tee joint to guide dust to enter a slag-dust separator; a slag-dust guiding port adopts a streamline baffle to guide slag and dust to enter the slag-dust separator with air flow, and has better guiding effect; and the sealing manner that the dynamic seal and static seal are combined, so that the sealing effect is better.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a dust removal device suitable for drilling in rock formations. Background technique [0002] With the country's further emphasis on the protection of stone cultural relics, the scope and intensity of cultural relics protection have further increased. Anchoring, as one of the conventional methods for the protection of stone cultural relics, is widely used in rock masses where cultural relics are present. Drilling rigs can be divided into pneumatic drills, electric drills, and hydraulic drills. Pneumatic drills are most widely used in forming holes for anchor cables and anchor rods. A large amount of dust and debris will be generated during the drilling and drilling process of the pneumatic drill. Dust can float for more than 1 kilometer, which will cause great damage to the health of construction workers; it will have a negative impact on the normal opening of scenic spot...
