Abstract
The utility model relates to the technical field of drilling equipment, in particular to a drill bit capable of increasing drilling efficiency. The drill bit resolves the problem that unsuccessful slag discharging in the prior art results in stop drilling or bit damages, the provided technical scheme includes that the drill bit capable of increasing the drilling efficiency comprises a drilling claw portion, a connecting portion and a joint portion, the outer surface of the drilling claw portion is equipped with a drilling claw, and the diameters of the drilling claw portion, the connecting portion and the joint portion are sequentially reduced. The drill bit is characterized in that guide chutes are disposed on the outer surface of the drilling claw portion, and the guide chutes and the drilling claw are separated from each other. Compared with the prior art, the drill bit has the advantages that a plurality of guide chutes form a spiral structure integrally, the guide chutes in high-speed rotation results in a mud pump principle, and rock slag is discharged fully, thereby increasing the discharging strength, effectively preventing stop drilling and bit damages caused by rock slag jamming, increasing the drilling efficiency, and effectively reducing the cost.
Description
Technical field:
The utility model relates to the drilling equipment technical field, is specifically related to a kind of drill bit that can improve drilling efficiency.
Background technology:
In the drilling process, drill bit creeps at a high speed with the rock stratum violent friction cuttings takes place, and can produce a large amount of rock slags, and the rock slag can stop up drill bit because deslagging is not smooth, influences it and creeps into, and cause stopping the brill accident, influences drilling efficiency; More can cause drill bit to damage when serious, cause very big loss.
Summary of the invention:
The utility model provides a kind of drill bit that can improve drilling efficiency, to solve the problem that causes left alone without help brill or damage drill bit because of deslagging is unfavorable that prior art exists.
For solving the problem that prior art exists, the technical scheme that the utility model provides is: a kind of drill bit that can improve drilling efficiency, comprise and bore claw, connecting portion and connector portions, bore claw and be provided with the brill pawl, the diameter of described brill claw, connecting portion and connector portions dwindles successively, it is characterized in that: the external surface that bores claw is provided with the water conservancy diversion skewed slot, described water conservancy diversion skewed slot and the alternate setting of brill pawl.
Above-mentioned water conservancy diversion skewed slot is the arcuation groove.Has better deslagging effect.
Compared with prior art, advantage of the present utility model is as follows: winding is at many water conservancy diversion skewed slots that bore the claw outside, constituted helical structure on the whole, in drilling process, the incline direction of water conservancy diversion skewed slot 4 is identical with the direction of rotation of drill bit, the water conservancy diversion skewed slot of high speed rotation, formed a slush pump principle, discharge the rock slag fully, strengthened the deslagging dynamics, the accident generation that has effectively prevented the left alone without help brill that causes because of the obstruction of rock slag and damaged drill bit has greatly improved drilling efficiency, effectively reduces cost.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Description of reference numerals is as follows:
1-bores claw, 2-connecting portion, 3-connector portions, 4-water conservancy diversion skewed slot.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
Referring to accompanying drawing, a kind of drill bit that can improve drilling efficiency, comprise and bore claw 1, connecting portion 2 and connector portions 3, bore claw 1 and be provided with the brill pawl, the diameter of described brill claw 1, connecting portion 2 and connector portions 3 dwindles successively, the external surface that bores claw 1 is provided with the water conservancy diversion skewed slot 4 of arcuation, described water conservancy diversion skewed slot 4 and the alternate setting of brill pawl.
During use, drill bit runs up, and winding has formed a slush pump at many water conservancy diversion skewed slots 4 that bore claw 1 outside because of rotating at a high speed, therefore can discharge the rock slag fully.
Claims (2)
1, a kind of drill bit that can improve drilling efficiency, comprise and bore claw (1), connecting portion (2) and connector portions (3), bore claw (1) and be provided with the brill pawl, the diameter of described brill claw (1), connecting portion (2) and connector portions (3) dwindles successively, it is characterized in that: the external surface that bores claw (1) is provided with water conservancy diversion skewed slot (4), described water conservancy diversion skewed slot (4) and the alternate setting of brill pawl.
