Abstract
The utility model relates to a parallel pneumatic drill bit, which comprises a pair of drilling trousers and two alloy sheets fixed on the drilling trousers; the two alloy sheets are parallel and symmetrically distributed on two sides of the center of the diamond trousers. The utility model provides a parallel air drill bit, adopt two parallel alloy pieces symmetric distribution on the drill bit, when the drill bit is reciprocal to strike the rock, under the rotation of drill bit, owing to adopt two alloy pieces, two alloy pieces are all out of the center of rotation, the alloy piece does not repeatedly strike the nick that the preceding impact produced sunken, only transversely strike the nick bulge that the preceding impact produced to form the splitting destruction to the nick bulge; the existing low-efficiency impact damage is changed, and the drilling speed of the drill bit is greatly improved.
Description
Technical Field
The utility model relates to a pneumatic drill bit field especially relates to a parallel pneumatic drill bit.
Background
The existing pneumatic drill bit is mostly a linear drill bit and a cross drill bit, and alloy sheets embedded on the surface of the existing pneumatic drill bit are arranged in a linear or cross shape. After the alloy sheet of the drill bit impacts the rock, the impacted rock is crushed, nicks are formed on the surface of the rock, and the drill bit forms centrosymmetric nicks on the surface of the rock along with the rotation and drilling of the drill bit, as shown in fig. 5, the nicks are radial and centrosymmetric nicks which are consistent with the alloy sheet of the drill bit and take the drill bit as the center, and are similar to a Chinese character 'mi', the nicks can be divided into nick bulges and nick depressions, and when the drill bit impacts the rock in a reciprocating mode, the alloy sheet of the drill bit can repeatedly impact the previously formed nicks, so that the drilling is realized. When the alloy sheet impacts the indented convex part, the main actions of the alloy sheet are friction damage to the convex part and impact damage to the concave part, and both damage forms are not favorable for drilling and have low efficiency.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a parallel air drill bit adopts two parallel alloy pieces, changes current low efficiency and strikes and destroy, improves the drilling speed of drill bit by a wide margin.
The utility model provides a technical scheme that its technical problem adopted is: a parallel pneumatic drill bit comprises a drill pants and two alloy sheets fixed on the drill pants; the two alloy sheets are parallel and symmetrically distributed on two sides of the center of the diamond trousers.
Further, the drilling trousers are provided with mounting grooves; two alloy sheets are welded in the mounting groove; an embedded welding seam is arranged between the two alloy sheets.
Furthermore, the two sides of the drilling trousers in the mounting groove are respectively provided with a slag discharge groove.
Further, a cavity is arranged inside the drilling trousers; the two sides of the mounting groove of the drilling trousers are respectively provided with a water through hole; the limber hole is communicated with the cavity.
The utility model has the advantages that: the utility model provides a parallel air drill bit, adopt two parallel alloy pieces symmetric distribution on the drill bit, when the drill bit is reciprocal to strike the rock, under the rotation of drill bit, owing to adopt two alloy pieces, two alloy pieces are all out of the center of rotation, the alloy piece does not repeatedly strike the nick that the preceding impact produced sunken, only transversely strike the nick bulge that the preceding impact produced to form the splitting destruction to the nick bulge; the existing low-efficiency impact damage is changed, and the drilling speed of the drill bit is greatly improved.

Detailed Description
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and embodiments, which are only used for explaining the present invention and are not limited to the protection scope of the present invention.
Examples
As shown in fig. 1 to 3, the present embodiment provides a parallel pneumatic drill bit, which comprises a pair of drilling trousers 1 and two alloy sheets 2 fixed on the drilling trousers 1; the two alloy sheets 2 are parallel and symmetrically distributed on two sides of the center of the diamond trousers.
In the parallel pneumatic drill bit of the embodiment, the drill pants 1 are provided with mounting grooves 6; two alloy sheets 2 are welded in the mounting groove 6; an embedded welding seam 5 is arranged between the two alloy sheets 2.
In the parallel pneumatic drill bit of this embodiment, the drilling trousers 1 are provided with the deslagging slots 3 on the two sides of the mounting slot 6 respectively.
In the parallel pneumatic drill bit of the embodiment, a cavity 7 is arranged inside the drill pants 1; the two sides of the mounting groove 6 of the drilling trousers 1 are respectively provided with a water through hole 4; the water through hole 4 is communicated with the cavity 7.
The parallel air drill bit of the embodiment adopts two parallel alloy sheets which are symmetrically distributed on the drill bit, when the drill bit impacts rocks in a reciprocating manner, notches formed on the rocks are shown in figure 4 under the rotation of the drill bit, and compared with the notches formed on the rocks by the air drill bit in the prior art shown in figure 5, because the two alloy sheets are adopted, neither alloy sheet is positioned on the rotation center, the alloy sheet does not impact notch depressions generated by front impact repeatedly, and only transverse impact is carried out on the notch convex parts generated by the front impact, so that the splitting damage to the notch convex parts is formed; the existing low-efficiency impact damage is changed, and the drilling speed of the drill bit is greatly improved.
The above-mentioned embodiments should not limit the present invention in any way, and all the technical solutions obtained by adopting equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
