Description
Technical field
The utility model relates to drilling technique field more particularly to a kind of drilling equipments.
Background technique
In engineering investigation drilling process, when the ability that drilling scouring media carries rock powder is less than the amount that rock powder generates, meeting
Cause the rock powder content at drilling hole bottom more and more, the rock powder of bottom hole is caused to accumulate serious problem；Simultaneously in the height of drilling tool
Under fast rotary squeezing, the rock powder of deposition is easily pressed further by hole wall, causes the mudcake formed on hole wall more and more thicker, hole
Annular gap between wall and drilling tool outer tube is more and more small, causes to creep into and returns unsmooth on flushing liquor, drilling machine overload occurs
Phenomenon, drilling efficiency is low, may cause when situation is serious drilling tool completely by rock powder be wrapped in bottom hole cause paste brill, burying, burning
The accidents such as brill.
Utility model content
The technical issues of the utility model solves: because rock powder expulsion efficiency is bad, the rock powder at drilling hole bottom is caused to be accumulated tight
The problem of weight.
The technical scheme adopted by the utility model to solve the technical problem is as follows: drilling equipment, including drilling tool, drilling rod and company
One end of connector, connector connects drilling tool, and the other end jointed rod of connector, further includes sediment tube, and the sediment tube is arranged
On drilling rod, one end of sediment tube is connect with connector, is formed between the other end and drilling rod of sediment tube and is connect powder mouth, in sediment tube
It is formed between drilling rod and connects powder chamber.
Further, connector is threadedly coupled with sediment tube.
Further, the outer profile diameter of sediment tube is not more than the outer profile diameter of drilling tool.
Further, the axial direction for connecing powder opening's edge drilling rod is inclined to set.
Further, the powder mouth that connects includes top and bottom；Along the inclined direction for connecing powder mouth, the top is located at remote
One end from drilling tool, the bottom are located at close to one end of drilling tool；It is formed after the inside bending in edge at top on sediment tube
Bending stopper.
The beneficial effects of the utility model are: by setting sediment tube one can be collected by sediment tube in boring procedure
Fixed rock powder avoids a large amount of rock powder from being deposited on bottom hole；Being collected simultaneously the rock powder in sediment tube can be with drilling through out；When each drilling
Terminate, mention when drilling through the heart, propose sediment tube together, and remove the rock powder of collection, boring procedure can be effectively prevented from and sent out in bottom hole
Raw rock powder accumulates serious problem；And then it can further avoid pasting the things such as brill, burying, the burning of bits because caused by depositing seriously rock powder
Therefore.
Detailed description of the invention
Fig. 1 is the perspective view of the explosion of drilling equipment described in the utility model；
In the figure, it is marked as drilling tool 1, drilling rod 2, connector 3, sediment tube 4, connect powder mouth 5, connect powder chamber 6, top 51, bottom 52,
Bending stopper 7.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, drilling equipment described in the utility model, including drilling tool 1, drilling rod 2 and connector 3, connector 3
One end connect drilling tool 1, the other end jointed rod 2 of connector 3 further includes sediment tube 4, and the sediment tube 4 is set in drilling rod 2
On, one end of sediment tube 4 is connect with connector 3, is formed between the other end and drilling rod 2 of sediment tube 4 and is connect powder mouth 5, in sediment tube 4
It is formed between drilling rod 2 and connects powder chamber 6.
In boring procedure, rock powder part can with returned on scouring media from hole month be discharged, and part then on return to height
In connecing after 5 or more powder mouth because self weight is sunk and is collected by connecing powder mouth 5 and is connect in powder chamber 6 accordingly for sediment tube 4；In this way
It avoids the part rock powder from being eventually deposited at bottom hole, and then avoids the problem that causing rock powder heavy deposition in bottom hole.
More specifically, connector 3 is preferably provided in the utility model to be threadedly coupled with sediment tube 4；It can facilitate in this way to taking
Tube cell 4 is dismantled with connector 3, so as to the corresponding structure member of installation and replacement.
Certainly, without loss of generality, screw thread company is all made of between connector 3 and drilling tool 1 and between connector 3 and drilling rod 2
It connects, to dismount.
In addition, without loss of generality, can freely be gone up and down with drilling rod 2 in drilling to meet sediment tube 4, corresponding sediment tube
4 outer profile diameter cannot necessarily be greater than the aperture of drilling, and the aperture to drill is usually corresponding with the outer profile of corresponding drilling tool 1
Diameter it is consistent, it is therefore desirable to be arranged sediment tube 4 outer profile diameter be not more than drilling tool 1 outer profile diameter.And usual feelings
Under condition, the outer profile diameter of setting sediment tube 4 is less than the outer profile diameter of drilling tool 1.
In addition, being easy to be cut on the hole wall of drilling in order to avoid connecing the entire edge of powder mouth 5 during taking bar, in turn
The problem of causing kelly.Powder mouth 5 is connect described in being further preferably arranged in the utility model to be inclined to set along the axial direction of drilling rod 2,
It connects 5 place plane of powder mouth and the axis of drilling rod 2 is inclined to set, as shown in Fig. 1.
Be obliquely installed connect powder mouth 5 in the case where, can also further take following specific setting: the powder mouth 5 that connects includes
Top 51 and bottom 52；Along the inclined direction for connecing powder mouth 5, the top 51 is located remotely from one end of drilling tool 1, the bottom 52
In one end close to drilling tool 1；Bending stopper 7 is formed on sediment tube 4 after the inside bending in edge at top 51.In this way, taking
During bar, the top 51 for connecing powder mouth 5 being obliquely installed is stopped due to being provided with bending stopper 7, can be effectively prevented from top
Portion 51 is cut on the hole wall of drilling, while bending stopper 7 can play guiding function during taking bar, can be effectively prevented from out
The problem of existing kelly.
More specifically, bending stopper 7 in drilling process is avoided to grind because keeping appropriate gap between bending stopper 7 and drilling rod 2
Damage drilling rod 2 even causes drilling rod 2 to break the accidents such as bar.
