Abstract

The utility model discloses a conical nozzle drill bit, which comprises a drill bit body, wherein the upper end of the drill bit body is provided with a plurality of drill bit teeth, and a gap is formed between the drill bit teeth, the gap is in a conical structure, and the drill bit teeth are provided with through holes; the utility model has the advantages of reasonable design, convenient to use can reduce the too fast phenomenon of the inboard loss of drill bit to improve the life of drill bit, simultaneously the utility model discloses the lower efficiency of digging of drill bit has also been improved.

Description

Conical nozzle drill bit

Technical Field

The utility model belongs to the technical field of the exploration equipment and specifically relates to a toper mouth of a river drill bit is related to.

Background

In the process of geological exploration, a drill bit is often required to be used for downward excavation exploration, the upper end of the traditional drill bit is only singly provided with drill bit teeth, so that in the downward excavation exploration process, the abrasion loss of the drill bit teeth is large, the long-term use of the drill bit is not facilitated, and the abrasion loss of the inner side of the drill bit teeth of the traditional drill bit is larger than that of the outer side when the traditional drill bit is used, so that the inner side of the drill bit teeth of the drill bit is abraded too fast, and the long-term use of the drill bit is not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the above-mentioned problem that proposes, provide a toper mouth of a river drill bit for this reason, including the drill bit body, the upper end of drill bit body is provided with between a plurality of drill bit tooth and the a plurality of drill bit tooth and is provided with the interval and forms the mouth of a river, the mouth of a river sets up the toper structure, be provided with the through-hole on the drill bit tooth, be provided with the bell groove on the terminal surface of drill bit tooth.

Preferably, the through hole has a circular structure.

The utility model has the advantages that: the utility model has the advantages of reasonable design, convenient to use can reduce the too fast phenomenon of the inboard loss of drill bit to improve the life of drill bit, simultaneously the utility model discloses the lower efficiency of digging of drill bit has also been improved.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic view of the overall structure of the present invention;

in the figure: 1. a drill bit body; 2. bit teeth; 3. a water gap; 4. a tapered groove; 5. and a through hole.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The conical nozzle drill bit shown in fig. 1 comprises a drill bit body 1, wherein a plurality of drill bit teeth 2 are arranged at the upper end of the drill bit body 1, gaps are formed among the drill bit teeth 2 to form a nozzle 3, the nozzle 3 is in a conical structure, through holes 5 are formed in the drill bit teeth 2, and conical grooves 4 are formed in the end faces of the drill bit teeth 2.

The through hole 5 is of a circular structure.

In the using process, the water gap 3 is arranged, so that when the drill bit body 1 operates, the drill bit body 1 can be conveniently filled with water, and a certain lubricating effect is achieved; the water gap 3 is arranged in a conical structure, so that the area of the inner side of the drill bit teeth 2 can be increased, the inner side and the outer side of the drill bit teeth are ensured to be basically synchronous in loss, and the service life of a drill bit is prolonged; the arrangement of the conical groove 4 can increase the contact surface between the front end of the drill bit body 1 and the geological to be explored, so that the downward digging efficiency of the drill bit body 1 is improved; the through hole 5 is arranged, so that water entering from the water gap can flow inside and outside the through hole 5, and the drill bit body 1 can be lubricated better.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
