Abstract

The utility model relates to a rotary deslagging and dedusting device for drilling of a pneumatic down-the-hole hammer. The device is provided with a hollow barrel housing which is annularly arranged outside a drill rod and sequentially consists of a lower flange sleeve pipe, a deslagging barrel and an upper barrel from bottom to top, wherein the inner upper part of the barrel housing is coaxially connected with a center pipe, which is annularly arranged outside the drill rod, through a tapered roller bearing, and the lower end of the center pipe is connected with a spherical capsule, of which the inner side wall is combined with the pneumatic down-the-hole hammer drill rod in an embracing and sealing way, through a connecting ring. When the device is used, the drill rod penetrates through the center pipe and the spherical capsule to enter into the bottom of a hole, the drill rod rotates to drive the spherical capsule, the connecting ring and the center pipe to rotate, and drilling slag at the bottom of the hole upwards returns along with high-pressure air, enters into the deslagging barrel after passing through a gap between the drill rod and the hole wall, is guided to a water pool through a deslagging opening and a guide glue pipe with dust, is subjected to dust fall treatment and is discharged. The device provided by the utility model is simple in structure, reliable in sealing and convenient to operate, and the drilling slag and dust can be directionally discharged, so that the cleanness and the tidiness of a work environment can be guaranteed.

Description

A kind of pneumatic down-hole hammer creeps into revolution deslagging dust arrester

Technical field

The utility model belongs to geology brill pick engineering and uses the facility technology field, relates to a kind of pneumatic down-hole hammer and creeps into revolution deslagging dust arrester.

Background technology

As the process of a comparative maturity, at present pneumatic down-hole hammer drilling construction technology just with its construction benefit height, adapt to characteristics such as the stratum ability is strong and obtain a large amount of promoting the use of in this area.Contain slag dust directly is discharged to the workplace from the gap between drilling rod and the hole wall problem but all exist in this technology use at present, cause the aperture severe contamination, cause very big influence environment and operating personnel (driller) are healthy; Although some rig also is provided with dust arrester, dust removing effects is all not ideal enough.

The utility model content

The purpose of this utility model is the problem that prior art exists is solved, thus provide a kind of simple in structure, easy to operate, can make the directed discharging of boring mud dust guarantee that clean, the clean and tidy pneumatic down-hole hammer of operating environment creeps into revolution deslagging dust arrester.

Be used to realize that the technical scheme of foregoing invention purpose is such: this pneumatic down-hole hammer creeps into revolution deslagging dust arrester has a hollow ladle bowl that is located on outside the drilling rod, said ladle bowl is constituted by lower flange sleeve pipe, deslagging bucket and last bucket from bottom to top successively, internal upper part at ladle bowl is coaxially connected with a core barrel that is located on outside the pneumatic down-hole hammer drilling rod by taper roll bearing, the ball-type capsule of an inside wall and drilling rod sealing obvolvent is arranged by the connecting ring tipping in the lower end of core barrel.

In above-mentioned revolution deslagging dust arrester, the deslagging bucket is connected with retaining mechanism by bottom end cover with going up between bucket, has slag-drip opening on the sidewall of deslagging bucket.

The technical solution of the utility model also comprises, the outside framework oil seal of protection bearing all is installed in the upper and lower of core barrel, the top of core barrel be equipped with combine with the drilling rod sealing on rubber cushion.

In the pneumatic down-hole hammer use, drilling rod passes core barrel and ball-type capsule enters at the bottom of the hole, ball-type capsule elasticity extension better performances can be held drilling rod tightly and be sealed, driving ball-type capsule, connecting ring and core barrel during the drilling rod rotation turns round together, has only relative motion up and down between drilling rod and the ball-type capsule, can effectively reduce the wearing and tearing of ball-type capsule like this, prolong the application life of ball-type capsule; Along with pneumatic down-hole hammer work is crept into, hole subdrilling slag enters the deslagging bucket with returning on the pressure-air by drilling rod and hole wall gap, and is directed to the pond by slag-drip opening and guiding sebific duct together together with dust, does depositing dust and handles and discharge.

Compared with prior art, the utlity model has following advantage:

1, this revolution deslagging dust arrester simple in structure, sealing is reliable, easy to operate, it can be discharged into the boring mud orientation from place far away, drilling machine construction place, the deslagging good dedusting effect can prevent the pollution of the environment effectively, can protect health of operators well again;

2, the good springiness of used ball-type capsule in the device, the drilling rod that can adapt between the φ 60-φ 89 uses, and ball-type capsule adopts special rubber materials to make, and anti-wear performance is good;

3, easy to maintenance, the applied range of dismounting of the present utility model, product can satisfy the demand of creeping in φ 350 following holes, also can be used for the boring mud discharging that mud creeps into, and it can guarantee the clean, clean and tidy of operating environment, effectively reduces dust pollution.

Description of drawings

Fig. 1 is the structural representation of a specific embodiment of the utility model.

Fig. 2 is a schematic top plan view of the present utility model.

The title of each label is respectively among the figure: 1-deslagging bucket, 2-ball-type capsule, 3-connecting ring, the 4-bottom end cover, the last bucket of 5-, 6-taper roll bearing, the 7-upper end cover, the last rubber cushion of 8-, 9-core barrel, 10-outside framework oil seal, the 11-slag-drip opening, the 12-retaining mechanism, 13-lower flange sleeve pipe, 14-drilling rod.

The specific embodiment

Below with reference to accompanying drawing the utility model content is described further, but actual fabrication structure of the present utility model is not limited in following embodiment.

Referring to accompanying drawing, the utility model is that a kind of pneumatic down-hole hammer of the directed discharging of boring mud that can make creeps into revolution deslagging dust arrester, it by deslagging bucket 1, ball-type capsule 2, connecting ring 3, bottom end cover 4, go up bucket 5, taper roll bearing 6, upper end cover 7, go up rubber cushion 8, core barrel 9, outside framework oil seal 10, retaining mechanism 12, lower flange sleeve pipe 13 etc. and partly form.Last bucket 5, deslagging bucket 1 and lower flange sleeve pipe 13 connect to form the hollow ladle bowl that is located on outside the pneumatic down-hole hammer drilling rod 14 successively; core barrel 9 respectively is connected with last bucket 5 by a dish taper roll bearing 6 up and down; core barrel 9 lower ends are connected with ball-type capsule 2 by connecting ring 3; core barrel 9 is equipped with the outside framework oil seal 10 of protection bearing up and down, and on the top of core barrel 10 rubber cushion 8 is installed.Ball-type capsule 2 has better elastic ductility, can hold drilling rod 14 tightly and seal, and can drive ball-type capsule 2, connecting ring 3 and core barrel 9 during drilling rod 14 rotations and turn round (having only relative motion up and down between drilling rod 14 and the ball-type capsule 2) together.Deslagging bucket 1 is connected with retaining mechanism 12 by bottom end cover 4 with last barrel 5, has slag-drip opening 11 on the sidewall of deslagging bucket 1.
