Described bullet type brill tooth and forward type bore tooth and are carbide drill tooth.
The beneficial effects of the utility model are:
1. bore tooth strengthen the abrasion resistance of work plane when broken rock by arranging forward type at work plane, ensure that work plane bores the permanent tooth ability of tooth to bullet type;
2. ensure when down-the-hold drill bit works by sludge groove, in time rock slag is discharged, reduce and repeat fragmentation, improve speed of punchinging.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the schematic cross-section that in the utility model, forward type bores tooth.
In figure, 1 drilling rod, 2 work planes, 3 inclined-planes, 4 bore tooth, and 41 bullet types bore tooth, and 42 forward types bore tooth, 5 watercourse ports, 6 smooth connection, 61 oblique lines, 62 valley line, 7 sludge grooves, 21 outer walls, 22 bottom surfaces, 23 upper bottom surfaces.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
See Fig. 1--Fig. 3.
The utility model discloses a kind of Novel down-the-hole drill, comprise drilling rod 1, described drilling rod 1 head end is provided with the work plane 2 with drilling rod 1 axis perpendicular, described work plane 2 periphery is provided with the inclined-plane 3 forming inclination angle with work plane 2, described periphery, inclined-plane 3 and drilling rod 1 outer wall are by smooth connection 6 transition, described work plane 2 with inclined-plane 3 are all embedded with some brill teeth 4, the bullet type that brill tooth 4 on described work plane 2 comprises spaced arrangement bores tooth 41 and forward type brill tooth 42, bore between tooth 42 at described forward type and be provided with a watercourse port 5 be communicated with drilling rod 1 internal water channel, abrasion resistance when strengthening work plane 2 at broken rock by arranging forward type brill tooth 42 at work plane 2, ensure that work plane 2 bores the permanent tooth ability of tooth 41 to bullet type, extend the application life of down-the-hold drill bit, spray cooling water by watercourse port 5 to cool the brill tooth 4 during work, improve the life-span of boring tooth 4, as preferably, outside the longitudinal section of described smooth connection 6, cause one section of oblique line 61 and one section of valley line 62 combine, and each transition position is level and smooth chamfering.
As preferably, it is cylindrical structural that described forward type bores tooth 2, and be provided with chamfering between the upper and lower bottom surface of described cylindrical structural and outer wall 21, described cylindrical structural embeds work plane 2 by bottom surface 22; After described cylindrical structural embeds work plane 2, cylindrical structural upper bottom surface 23 higher than or be positioned at same plane with work plane 2, when down-the-hold drill bit operationally, after ore bed is crashed to pieces, before ore touches work plane 2, first to higher than or and work plane 2 be positioned at conplane cylindrical structural upper bottom surface 23 and grind, impact, thus ensure that the bullet type on work plane 2 bores position, tooth 41 place to a great extent, add abrasion resistance, improve permanent tooth performance, extend the application life of drill bit.
