Description
Technical field
This utility model relates to engineering driller, digs particularly to a kind of rotation for big erratic boulder earth-boring pouring pile hole
Drill bit of drilling machine.
Background technology
Erratic boulder typically refers to the underground particle diameter ratchel more than 200mm, generally composes and exists in sand-pebble layer.Erratic boulder stratum
Hole between granule is big, do not have cohesive strength, arrange irregular, not of uniform size；And the big particle diameter erratic boulder containing high intensity is difficult
With broken, permeability is big, is often accompanied by the subsoil water enriched, brings great difficulty to bored pile construction.
In bored pile construction, rotary drilling rig have speed of fulfiling hole fast, without extrusion effect, little without earthquake, noise and
Without advantages such as mud circulations, it is widely applied.To general cohesive soil, banket, the ground such as muck soil, sand and land pebble
Layer, rotary drilling rig passes through conveniently, and pore-forming is effective.
Rotation is dug bit drill and opened body drill bit is all the drill bit being most widely used in rotary drilling rig construction, it is adaptable to sand ovum
Stone stratum.Employing opens body drill bit when creeping into, and boring mud easily causes a large amount of boring mud during carrying slag after filling drilling bucket and drops, merit of holing
Imitate the very end.
Existing rotation dig bit drill due in big erratic boulder stratum erratic boulder arrange random, not of uniform size, cause section
Uneven, bucket tooth discontinuity when pore-forming creeps into, vibrations are big, and counteracting force the most easily occurs that broken teeth, perpendicularity should not be controlled
System, big drift cobble fish for the situations such as difficulty.
Therefore, it is irrigated pile driving construction on rich water erratic boulder stratum, also there is no ideal erratic boulder treating method.In order to subtract
Bucket tooth discontinuity when few traditional rotary drilling rig pore-forming creeps into, counteracting force the most easily occurs that broken teeth, perpendicularity should not be controlled
System, big drift cobble fish for the situations such as difficulty, are badly in need of redesigning drilling bit of rotary-digging drilling rig, thus solve this technical barrier.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of for big erratic boulder earth-boring pouring pile hole
Drilling bit of rotary-digging drilling rig, to be effectively improved hole quality and the pore-forming efficiency of big erratic boulder earth-boring bored concrete pile.
The technical scheme that the above-mentioned technical problem of this utility model solution is taked is as follows:
Drilling bit of rotary-digging drilling rig for big erratic boulder earth-boring pouring pile hole of the present utility model, including cylinder and setting
At the bottom of bucket bottom it, it is characterized in that: include having at the bottom of the upper strata bucket in double fanning strip face at the bottom of described bucket, lower floor struggles against at the end, struggles against in upper strata
Back welding is connected on the lower end of cylinder, and lower floor's bucket centre at the bottom of the end, upper strata bucket is rotatably connected, and arranges on the lower floor bucket end
There is the center riser downwardly extended；The inner side of two scallops being located along the same line at the bottom of the bucket of described upper strata is fixedly installed downwards
The baffle plate extended, (fixing the setting in a row in the inner side of two scallops being located along the same line downwardly extends pick at the lower floor bucket end；
At the bottom of the bucket of described upper strata, the arc length of opening is not less than 40cm at lower floor the bucket end.
The beneficial effects of the utility model are, for big erratic boulder stratum, and the situation that especially erratic boulder particle diameter ＞ 30cm is more,
Optimize bucket bottom structure and opening size, can quickly drill through the erratic boulder of ＞ 30cm when churning driven enters, successfully solve drill bit
Pick abrasion is big, construction cost high, rate of penetration slow-motion and cause the situation of collapse hole.

Component name shown in figure and corresponding labelling: at the bottom of cylinder 10, upper strata bucket 11, lower floor the bucket end 12, center riser
13, pick 14, baffle plate 15, arc length K.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, this utility model is further described.
With reference to Fig. 1, Fig. 2 and Fig. 3, the rotary drilling rig for big erratic boulder earth-boring pouring pile hole of the present utility model
Upward view, including cylinder 10 be arranged at the bottom of the bucket bottom it.Include having at the bottom of the upper strata bucket in double fanning strip face 11 at the bottom of described bucket,
The lower floor bucket end 12, at the bottom of the bucket of upper strata, 11 are welded on the lower end of cylinder 10, and at the bottom of lower floor the bucket end 12, upper strata bucket, the centre of 11 can be revolved
Turn and connect, and be provided with, on the lower floor bucket end 12, the center riser 13 downwardly extended.At the bottom of the bucket of described upper strata, 11 are positioned at same straight line
On the inner side of two scallops be fixedly installed the baffle plate 15 downwardly extended, two fans that lower floor is located along the same line at the bucket end 12
Fixing the setting in a row in the inner side on shape limit downwardly extends pick 14.Arc length K of opening at the bottom of the bucket of described upper strata 11, at lower floor the bucket end 12
Not less than 40cm.
When churning driven enters downwards, cylinder 10 rotates forward, and under center riser 13 acts on, the lower floor bucket end 12 is relative to upper strata
The bucket end 11, rotates to an angle, by arrange baffle plate 15 limit at the bottom of the bucket of upper strata 11, the size of two openings at the lower floor bucket end 12, with
Shi Liyong pick 14, will float cobble and soil loads in drill bit cylinder 10.When cylinder 10 reversely rotates, act at center riser 13
Under, lower floor reversely rotates certain angle relative at the bottom of the bucket of upper strata 11 in the bucket end 12, is closed by opening, by rig lifting device with flexible
Cylinder 10 is proposed to unload outside hole soil by formula drilling rod.
This utility model, for big erratic boulder stratum, the situation that especially erratic boulder particle diameter ＞ 30cm is more, optimizes bucket bear building-up
Structure and opening size, can quickly drill through the erratic boulder of ＞ 30cm when churning driven enters, and successfully solves drill bit pick and weares and teares greatly, executes
Work cost is high, rate of penetration slow-motion and cause the situation of collapse hole.
The above principle more of the present utility model that simply explain through diagrams, is not intended to be confined to this utility model
Shown in and described concrete structure and the scope of application in, therefore every corresponding amendment being likely utilized and equivalent, all
Belong to the apllied the scope of the claims of this utility model.
