Abstract
The utility model relates to a diamond compact bit, which comprises a bit body and a water hole arranged in the bit body. A plurality of cutting blocks are inlaid onto the bit body, and the included angle alpha between the axis of the bit body and the axis of the water hole is 45 degrees. The water hole of the diamond compact bit is larger in inclination, so that the recoil force of mud is smaller when the bit is operated, a chip removal effect is excellent, repeated cutting can be avoided, and the drilling rate of the bit is increased.
Description
Technical field
The utility model relates to a kind of diamond compact bit.
Background technology
The hydrophthalmia inclination angle of conventional diamond compact bit is all smaller, and scope is between 0～25 °, because the hydrophthalmia inclination angle is more little, the recoil strength of mud is big more during drill bit work, and the chip removal effect is not fine, Repeated Cutting, and the drill bit rate of penetration is very slow.
The utility model content
The utility model provides a kind of diamond compact bit to the above-mentioned deficiency that existing diamond compact bit exists.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of diamond compact bit comprises bit body; With the hydrophthalmia that is arranged in the said bit body; Inlay a plurality of cutting pieces on the said bit body, the angle between the axis of said bit body and the axis of hydrophthalmia is 45 °.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said cutting piece is alloy and/or Buddha's warrior attendant stone.
Further, be connected with disconnectable water nozzle on the said hydrophthalmia.
The beneficial effect of the utility model is: the utility model diamond compact bit hydrophthalmia inclination angle is bigger, and the recoil strength of mud is less when making drill bit work, and the chip removal effect is fine, helps avoiding Repeated Cutting, improves the drill bit rate of penetration.

Description of drawings
Fig. 1 is the structural representation of the utility model diamond compact bit.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1, said diamond compact bit comprises bit body 1 and is arranged at the hydrophthalmia 2 in the said bit body 1 that inlay a plurality of cutting pieces 4 on the said bit body 1, the angle between the axis of the axis of said bit body 1 and hydrophthalmia 2 is 45 °.Said cutting piece 4 is alloy and/or Buddha's warrior attendant stone.Be connected with disconnectable water nozzle 3 on the said hydrophthalmia 2.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
