Research shows, diamond head affects the character that maximum factor is rock, especially the hardness of rock and crack degree; Along with the increase of rock fracture degree, the diamond head serviceability of each type all decreases. And, along with the increase of rock hardness, the impact of the performance of diamond head is significantly increased by rock fracture. Because can form a large amount of coarse particles rock dust when creeping into fractured rock, they can not be drained in time, rapidly by drill bit end, a large amount of coarse particles rock dust will be made to repeat at bit face broken, cause carcass and diamond sharply to wear and tear; Greatly reduce penetration rate and rate of penetration, add the energy input in breaking up rock process.
Summary of the invention
The technical problem to be solved in the present invention is, for existing drill bit when creeping into complicated crack, when crushing hard and very hard rock, penetration rate is poor, the defect that rate of penetration is low and energy input is high, a kind of carcass lip face is provided to be the diamond head of wedge shape, improve rate of penetration, increase headway per drill bit, reduce the energy input in drilling process.
The present invention solves the problems of the technologies described above the technical scheme adopted to be:
A kind of carcass lip face is the diamond head of wedge shape, comprise frame of the bit, carcass lip face, the mouth of a river, described carcass lip face comprise some, around being arranged on frame of the bit, the described mouth of a river is arranged between carcass lip face, described carcass lip face by fan-shaped block, carcass wedge face, form hole wall part (external diameter) and form rock core part (internal diameter) and form, whole carcass lip face is wedge shape.
By such scheme, described carcass wedge face, formation hole wall part and the equal relative sector block inclination of the rock core part that formed (i.e. the outer surface inclination of the upper surface inclination of carcass wedge face relative sector block, formation hole wall part relative sector block, the inner surface inclination forming rock core part relative sector block).
By such scheme, the upper surface angle of inclination of described carcass wedge face relative sector block is 15 ~ 40 degree; The outer surface angle of inclination of described formation hole wall part relative sector block is 15 ~ 40 degree; The inner surface angle of inclination of described formation rock core part relative sector block is 15 ~ 40 degree.
The principle of work of the present invention: adopt carcass lip face be the diamond head of wedge shape, fan-shaped block, the carcass wedge face of drill bit, forms hole wall part and forms rock core part and steadily enter cutting line, eliminates the impact of moving load (vibration), fragmentation hole bed rock stone. Meanwhile, washing fluid arrives the fan-shaped block of drill bit, angle of inclination is carcass wedge face, the formation hole wall part of 15 ~ 40 degree and is formed after below rock core part, enters in the rock being broken. Owing to 15 ~ 40 degree, angle of inclination can produce water conservancy kinetic effect, i.e. toughness wedge effect, it is possible to produce effective pre-crushing zone and fracture area, reduces the energy input of breaking up rock process.
Compared with prior art, the invention has the beneficial effects as follows: adopt wedge shape carcass lip face so that when creeping into, produce effective pre-crushing zone and fracture area, eliminate the impact of the travelling load in drilling process, reduce the energy input of breaking up rock process; When being applicable to the crack of complexity, the rock stratum on crushing hard and very hard rock and interbedding of soft and hard rocks stratum is crept into, improve drill speed, increase headway per drill bit, increase the use range of drill bit formation drilling, solve bit life in this kind of stratum is crept into low and creep into the low problem of drilling speed; Applicability is strong, has wide market outlook.
