In stating, it is to be understood that if the orientation or positional relationship for having the instructions such as term " on ", "lower", "left", "right" is based on attached drawing
Shown in orientation or positional relationship, be merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion institute
The device or element of finger must have a particular orientation, be constructed and operated in a specific orientation, therefore position pass is described in attached drawing
The term of system only for illustration, should not be understood as the limitation to this patent, for those of ordinary skill in the art and
Speech, can understand the concrete meaning of above-mentioned term as the case may be.
The realization of the utility model is described in detail below in conjunction with specific embodiment.
Shown in referring to Fig.1, preferred embodiment is provided for the utility model.
The high-efficient drilling pipe of rock cutting, comprising:
Drilling bucket 1, drilling bucket 1 have the holding tank of downwardly facing opening, and holding tank is for accommodating the rock dug out in drilling process；
Multiple brill teeth 2, multiple lower part detachable connections for boring tooth 2 and drilling bucket 1 bore and are connected with alloy head 3 on tooth 2.
The high-efficient drilling pipe of the rock cutting of above-mentioned offer, by the way that drilling bucket 1 is arranged, drilling bucket 1 has the receiving of downwardly facing opening
Slot, holding tank is for accommodating the rock dug out in drilling process；Multiple brill teeth 2, multiple brill teeth 2 and the lower part of drilling bucket 1 are detachable
Formula connection bores and is connected with alloy head 3 on tooth 2；In this way, when using drilling pipe rotary digging drilling soil layer or unconsolidated formation, it is only necessary in drilling bucket 1
The less brill tooth 2 of upper installation number, and the hardness requirement for boring 2 type of tooth does not need too high, has saved economic cost, when needing to revolve
When digging solid rock layer, installation number is more on drilling bucket 1 and the higher brill tooth 2 of hardness, and when construction, operator can be with
According to the specific strength conditions on rotary digging stratum and rock stratum, selects the suitable tooth 2 that bores to count amount and type, provided greatly to operator
Convenience, and after boring the work a period of time of tooth 2 and wear, directly replacement avoids and replaces entire drilling pipe, saving
Resource reduces costs, while rotary digging speed is fast, and rotary digging is high-efficient.
Specifically, tooth 2 and drilling bucket 1 are bored by the first connection structure detachable connection, the first connection structure includes from brill
Bucket 1 be downwardly extending connecting plate 4, be formed in connecting plate 4 the first threaded hole with the first internal screw thread, be formed in brill tooth
The second threaded hole with the second internal screw thread on 2 for the screw rod across the first threaded hole and the second threaded hole and is used for
The nut of standing screw.
As such, it is desirable to tooth 2 will be bored when being mounted on drilling bucket 1, it only need to be by first the second threaded hole of threaded hole face, by screw rod
Screw rod is fixed also cross the first threaded hole and the second threaded hole, then with nut, bores tooth 2 and drilling bucket 1 in this way, just realizing
It is fixed, easy to operate, fix stably；When needs, which will bore tooth 2, to be disassembled from drilling bucket 1, it is only necessary to by nut from screw rod
It backs out, screw rod is taken out from the first threaded hole and the second threaded hole.This detachable connection structure is only that this is practical
A kind of novel preferred connection structure, but it is not limited only to the connection structure.
Furthermore the connection type for boring tooth 2 and alloy head 3 is detachable connection；In this way, operator can be according to actually making
With environment and use demand, selects suitable alloy head 3 to be mounted on and bore on tooth 2, bring great advantage to the user, alternatively,
When long-time uses alloy head 3,3 serious wear of alloy head is unable to meet production demand, and user only need to be by old alloy head 3
It removes, new alloy head 3 is installed.
Specifically, tooth 2 and alloy head 3 are bored by the second connection structure detachable connection, the second connection structure includes shape
At in the third threaded hole with third internal screw thread bored on tooth 2 and be formed on alloy head 3 can be with third screw-internal thread fit
External screw thread, alloy head 3 and bore tooth 2 and be cooperatively connected by third internal screw thread and external screw thread；In this way, when needing to pacify alloy head 3
It mounted in when boring on tooth 2, screws in alloy head 3 to third threaded hole, keeps the external screw thread of alloy head 3 and third screw-internal thread fit solid
It is fixed；When needing to remove alloy head 3 from brill tooth 2, alloy head 3 is screwed down from brill tooth 2, it is simple to operate.
Second connection structure is only a kind of preferably specific detachable connection structure provided by the utility model；But the utility model is not
It is only limitted to the structure.
Preferably, it bores on tooth 2 and is disposed with multiple third threaded holes, for being threadedly engaged multiple alloy heads 3；In this way, operation
Person can select to install appropriate number of alloy head 3, provide the user greatly according to the strength conditions on practical rotary digging stratum
It is convenient.
Furthermore the inner wall of holding tank is provided with the 4th internal screw thread 6 for blocking rock；In this way, being crept into drilling pipe rotary digging
During, drilling bucket 1 constantly rotates, and the internal screw thread of the inner wall of the holding tank of drilling bucket 1 will block in holding tank during rotation
Rock block when hanging out the rock block in the holding tank of drilling bucket 1 to outside hole, rock can be effectively prevented in this way, lifting drilling rod
Block is fallen, and improves rotary digging efficiency.
Preferably, the section of the 4th internal screw thread 6 is trapezoidal, and the section of the 4th internal screw thread 6 is trapezoidal can to prevent internal screw thread
The age of a draught animal wear damage occurs because meticulous, improve the working life of internal screw thread.
In the present embodiment, drilling bucket 1 is in a circular table shape.
Preferably, the diameter of the upper section of drilling bucket 1 is smaller than lower section；In this way, the outer wall of drilling bucket 1 and the contact surface of hole wall
Product is smaller, and collapse hole caused by due to drilling bucket 1 rubs can be effectively prevented.
In the present embodiment, the bindiny mechanism 5 for jointed rod is provided at the top of drilling bucket 1；By bindiny mechanism 5, realize
Drilling pipe is fixedly connected with drilling rod, easy to connect and secured.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
