Abstract
The utility mode relates to a novel percussion drill which comprises a drill body and a drill pipe, wherein the drill main body is provided with a plurality of drill teeth. At least two air holes are placed on the front lateral side of the drill main body. A certain angle is provided between the air holes and the axial direction of the drill. The air holes are communicated with a hollow part of the drill pipe. Because the air holes are placed on the front lateral side of the drill body, wherein the air holes are communicated with the hollow part of the drill pipe, during work process of the drill, airstreams flow into the air holes of the drill through the hollow part of the drill pipe, and rock slag produced during hole drilling process can be discharged timely, and thereby hole drilling efficiency of the drill is improved.
Description
Technical field
The utility model relates to a kind of drill bit, particularly relates to a kind of for the drill hammer than incompetent bed.
Background technology
Along with the day by day lifting of science and technology, the refinement of boring bar tool, and the lifting of production efficiency for the demand of respond to the market, have occurred for the percussion bit than incompetent bed.This drill bit is connected with impactor when work, and impactor will drive the drill bit impact rock again when driving bit.For this high-abrasive material of rock, the penetration rate that has improved greatly rig is combined in the impact of drill bit with rotating photo, the speed of response of rock slag has also improved greatly simultaneously, so that the rock slag can not be discharged timely, this has brought great inconvenience just for the boring work of rig.
The utility model content
The technical problems to be solved in the utility model provide a kind of simple in structure, cost is low and can in time clear up the drill bit of rock slag.
In order to solve the problems of the technologies described above, the utility model drill hammer, comprise drill body and drilling rod, be provided with a plurality of brill teeth on the wherein said drill body, side, the place ahead at described drill body offers at least 2 air vents, described air vent and drill bit shaft are in a certain angle, and described air vent communicates with the hollow parts of drilling rod.
The utility model drill hammer, the quantity of the air vent that the side, the place ahead of wherein said drill body is offered is 2.
The utility model drill hammer, wherein said air vent and drill bit shaft are to being 45 ° of angles.
The utility model drill hammer, the front portion of wherein said drill body offer 5 grooves, two groove settings that wherein coincide with described air vent wider and run through the drill body front portion.
Compared with prior art, the utility model drill hammer, offer the air vent that communicates with the drilling rod hollow parts by the side, the place ahead at drill body, in the rig course of work, air-flow flows into the drill bit air vent from the drilling rod hollow parts, the rock slag that produces in the boring procedure is in time discharged, thereby improved the drilling efficiency of rig.
Below in conjunction with accompanying drawing drill hammer of the present utility model is described further.
Description of drawings
Fig. 1 is the first shaft side figure of the utility model drill hammer;
Fig. 2 is the second shaft side figure of the utility model drill hammer;
Fig. 3 is the front view of the utility model drill hammer.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, the utility model drill hammer, comprise drill body 1 and drilling rod 2, wherein be provided with a plurality of brill teeth 11 on the drill body 1, side, the place ahead at drill body 1 offers at least 2 air vents 12, air vent 12 and drill bit shaft are in a certain angle, and air vent 12 communicates with the hollow parts 21 of drilling rod 2.
As preferred version of the present utility model, the quantity of the air vent 12 that the side, the place ahead of drill body offers is 2.
As preferred version of the present utility model, air vent 12 and drill bit shaft are to being 45 ° of angles.
As preferred version of the present utility model, the front portion of drill body 1 offers 5 grooves 13, and it is wider and run through drill body 1 front portion that two grooves 13 that wherein coincide with air vent 12 arrange.
In the rig course of work, air-flow flows into the air vent 12 of drill bit from the hollow parts 21 of drilling rod 2, thereby the rock slag that produces in the boring procedure is blown out from the hole, avoided air vent 12 when drill bit is worked, to be stopped up by the soft rock slag and be designed with to the air vent 12 of angle at 45 ° with drill bit shaft.And offer 5 grooves 13 in the front portion of drill body 1, it is wider and run through drill body front portion 1 that two grooves 13 that wherein coincide with air vent 12 arrange, this embodiment has guaranteed that the rock slag can be smoothly under the airflow function of air vent 12 discharges from boring, thereby has improved the operating efficiency of rig.
Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
