Abstract

The utility model discloses a rock drill bit, which relates to the technical field of rock drill equipment and solves the technical problem that the effect of discharging broken stones and silt through water outlets on the existing drill bit is not good; the utility model has the advantage of more reasonable water outlet design and better gravel discharge effect.

Description

Drill bit of rock drill

Technical Field

The utility model belongs to the technical field of rock drill equipment, and particularly relates to the technical field of rock drill bits.

Background

In the fields of geological exploration, mining, tunnel excavation, rock drilling engineering and the like, rock drilling is required to be carried out by utilizing a rock drilling machine, and the structural performance of a drill bit matched with the rock drilling machine is closely related to the working efficiency and the labor intensity.

At present, when rock drilling is carried out, small broken stones in a drill hole can fall between a drill bit and a hole wall, the broken stones and silt are discharged through water outlet holes in the drill bit to reduce the resistance of the drill bit, and the effect of discharging the broken stones and the silt through the water outlet holes in the existing drill bit is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, and provides a rock drill bit.

The technical scheme adopted by the utility model is as follows:

the utility model provides a rock drill bit, includes integrated into one piece's bottom and head, the bottom upper surface is connected with the head, the bottom is cylindric, and the head is cross and falls into four faces with the bottom upper surface, will every the face is established to the standard face, is equipped with a plurality of first archs on the head, and is adjacent all be equipped with first apopore between the first arch.

Preferably, the standard surfaces are provided with first grooves, and the bottoms of the first grooves are provided with second water outlet holes.

Preferably, the outer wall of the bottom is provided with four second grooves, and the second grooves are respectively connected with one first groove.

Preferably, the bottoms of the second grooves are provided with third water outlet holes.

Preferably, a plurality of second bulges are arranged on two sides of the second groove and are arranged at intervals along the length direction of the second groove.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

according to the utility model, the drill bit is provided with a plurality of water outlets, compared with the prior art, the gravel discharging effect is better due to the fact that the water outlets are more reasonable in design, particularly, first water outlets are formed between adjacent first bulges on the head, a second water outlet is formed in the bottom of the first groove, a third water outlet is formed in the bottom of the second groove, gravel silt is flushed into the first groove through the first water outlets, the gravel silt is flushed onto the second groove through the second water outlet, and finally the gravel silt is discharged out of the drill bit through the third water outlet.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the case of the example 1, the following examples are given,

referring to fig. 1-2, a rock drill bit, includes integrated into one piece's bottom 1 and head 6, 1 upper surface in bottom is connected with head 6, and bottom 1 is cylindric, and head 6 is cross and falls into four faces with 1 upper surface in bottom, will every the face is established to the standard surface, is equipped with a plurality of first archs 7 on the head 6, and is adjacent all be equipped with first apopore 8 between the first arch 7.

All be equipped with first recess 4 on the standard face, 4 tank bottoms of first recess are equipped with second apopore 5. The bottom of the first groove 4 is arc-shaped.

The outer wall of the bottom 1 is provided with four second grooves 3, and the second grooves 3 are respectively connected with one first groove 4. Each first groove 4 corresponds to one second groove 3, and one end of each first groove 4 extends into the second groove 3 and is communicated with the second groove. The first groove 4 and the second groove 3 are communicated to facilitate the discharge of gravels and silt out of the drill bit. The groove bottom of the second groove 3 is arc-shaped.

And third water outlet holes 9 are formed in the bottoms of the second grooves 3. And the third water outlet hole 9 is used for flushing away broken stones and silt on the second groove 3.

And a plurality of second bulges 2 are arranged on two sides of the second groove 3, and the second bulges 2 are arranged at intervals along the length direction of the second groove 3. Protruding 2 of second and the distance of 1 outer wall in bottom establish to protruding height, and height difference is designed to the protruding height of two adjacent protruding 2 of second, means, and is adjacent protruding height is certain height difference of different existence, just height difference is not more than 3mm, consequently, here its main function of protruding 2 of second is for avoiding the drill bit card to pull out in the drilling, and the height difference of design makes protruding 2 of second pull out from the drilling more easily, has prolonged the life of drill bit.

In the utility model, a plurality of water outlets are designed on the drill bit, compared with the prior art, the gravel discharging effect is better due to the fact that the water outlets are more reasonable in design, particularly, first water outlets 8 are formed between adjacent first bulges 7 on the head 6, second water outlets 5 are formed in the bottoms of the first grooves 4, third water outlets 9 are formed in the bottoms of the second grooves 3, gravel silt is flushed into the first grooves 4 through the first water outlets 8, the gravel silt is flushed onto the second grooves 3 through the second water outlets 5, and finally the gravel silt is discharged out of the drill bit through the third water outlets 9.

In addition, it should be noted that a connection hole connected with the drill rod is formed in the bottom of the drill bit, and the coolant enters the connection hole along a water path inside the drill rod in the prior art, and the present invention is not described in further detail.
