Description
Technical Field
The utility model relates to a diamond compact anchor rod drill bit.
Background
When the coal mine tunnel is tunneled, the safe, quick, efficient and stable-performance anchor rod drill bit plays a key role, and the quality of the drill bit performance is directly related to the drilling efficiency and the drilling cost.
At present, the traditional diamond composite sheet anchor rod drill bit for drilling supporting meshes is structurally characterized in that a nest slot for welding a diamond composite sheet is processed at the front end of a columnar steel body, the diamond composite sheet is welded in the nest slot, and the diamond composite sheet is used as a cutting tooth of the drill bit.
Generally, there are two types of conventional diamond compact rock bolt bits, one of which is a full diamond compact; the other is to weld a half diamond compact at the socket. When the diamond compact welding nest slot is particularly used, as the longitudinal front angle of the welding nest slot is larger (10 degrees to 15 degrees), affecting drilling speed and discharging powder.
Disclosure of Invention
The utility model overcomes the defects existing in the prior art and provides the diamond compact anchor rod drill bit.
In order to solve the technical problems, the utility model adopts the following technical scheme: a diamond compact rock bolt drill bit, comprising:
a drill bit base;
the drill bit crown part is arranged on the top of the drill bit matrix;
the method is characterized in that: the top of drill bit crown be equipped with two drill bit wings, all be equipped with the nest groove in one side at every drill bit wing top the nest inslot all be fixed with the diamond compact piece, be equipped with at the opposite side at every drill bit wing top with the corresponding back inclined plane of nest groove drill bit wing lateral wall below the diamond compact piece on all be equipped with preceding inclined plane the below of preceding inclined plane all be equipped with the side slope.
In the structure, the included angle between the reclining inclined plane and the horizontal plane is 30-45 degrees.
Compared with the prior art, the utility model has the beneficial effects that: the diamond composite sheet anchor rod drill bit has reasonable structural design, and the continuous front inclined surface and the continuous side inclined surface are arranged on the side wall of the drill bit blade below the nest groove, so that the powder discharging capability of the drill bit during drilling can be remarkably improved, common problems of buring, sticking, burning and the like in the working process are solved, the drilling efficiency is improved, and the production cost is saved.
Drawings
FIG. 1 is a schematic view of a diamond compact rock bolt drill bit according to an embodiment of the present utility model;
fig. 2 is a schematic diagram of a diamond compact rock bolt drill bit according to an embodiment of the present utility model.
In the figure:
1. a drill bit base; 2. a bit crown; 3. a drill bit blade; 4. a socket; 5. a diamond compact; 6. a reclining incline; 7. a front inclined surface; 8. and a side inclined surface.
Detailed Description
The following describes in further detail the embodiments of the present utility model with reference to the drawings and examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.
As shown in fig. 1-2, a diamond compact rock bolt drill bit, comprising:
a bit body 1;
a bit crown 2 arranged on top of the bit body 1;
the method is characterized in that: the top of drill bit crown 2 be equipped with two drill bit wings 3, all be equipped with nest 4 in one side at every drill bit wing 3 top the nest 4 in all be fixed with diamond compact 5, be equipped with at the opposite side at every drill bit wing 3 top with the corresponding back inclined plane 6 of nest 4 drill bit wing 3 lateral wall below diamond compact 5 on all be equipped with preceding inclined plane 7 the below of preceding inclined plane 7 all be equipped with side inclined plane 8.
In the structure, the included angle between the back inclined plane 6 and the horizontal plane is 30-45 degrees, the included angle between the back inclined plane 6 and the horizontal plane can directly influence the tooth entering speed and the cutting tooth strength, and the back inclined plane has good tooth entering speed and cutting tooth strength within the range of 30-45 degrees.
When the diamond composite sheet anchor rod drill bit of the utility model works specifically, a half diamond composite sheet (such as the diamond composite sheet in the structure of the diamond composite sheet anchor rod drill bit) or a whole diamond composite sheet can be arranged in the nest groove. The diamond composite sheet anchor rod drill bit has reasonable structural design, and the continuous front inclined surface and the continuous side inclined surface are arranged on the side wall of the drill bit blade below the nest groove, so that the powder discharging capability of the drill bit during drilling can be remarkably improved, common problems of buring, sticking, burning and the like in the working process are solved, the drilling efficiency is improved, and the production cost is saved.
While the foregoing is directed to the preferred embodiments of the present utility model, it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present utility model (e.g., disposing a full piece diamond compact in a socket), and such modifications and variations should also be considered as being within the scope of the present utility model.
