Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a drilling drill bit. Background Art

[0002] A karst drilling drill bit is a drill bit specially used for drilling operations in karst geology.

[0003] When drilling, the drill rod of the existing karst drilling drill bit needs to be fed downward gradually so that the drill bit can smoothly perform the drilling operation. The drilling depth of the drill bit can be controlled by controlling the feed speed of the drill rod. The deeper the drill bit drills, the more cement mixture will be drilled out, and the cement mixture will stick to the connection between the drilling rig and the drill bit, so that the connection will be slippery. As a result, when disassembling the drill bit, the cement mixture needs to be cleaned first, and then the drill bit is disassembled, which affects the work efficiency. Utility Model Content

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, and provides a drilling drill bit, including a drill bit body 100, and also including

[0028] A blocking cover 101 is slidably disposed outside the drill body 100, and the blocking cover 101 is used to block the cement mixture;

[0029] The swing assembly 200 is disposed on the drill body 100 and connected to the blocking cover 101 and the drill body 100 so as to use the swing assembly 200 to guide the position of the cement mixture generated by the drill body 100 when the drill body 100 is working.

[0030] Furthermore, the swinging assembly 200 includes a sliding ring 201 slidably disposed on the drill bit body 100 . When the sliding ring 201 slides up and down along the drill bit body 100 , the cement mixture attached to the drill bit body 100 can be wiped off.

[0031] Furthermore, a circular groove 202 is provided on the sliding ring 201, and an annular body 203 is provided on the blocking cover 101. The annular body 203 is rotatably arranged on the circular groove 202. When the drill body 100 rotates, the sliding ring 201 rotates synchronously, and the circular groove 202 on the sliding ring 201 rotates along the annular body 203, so that the sliding ring 201 and the blocking cover 101 rotate relative to each other.

[0032] Usage process: When the drill bit body 100 is working to produce cement mixture, the cement mixture is blocked by the blocking cover 101, and when the sliding ring 201 slides up and down, the cement mixture attached to the drill bit body 100 is wiped off.

[0033] Example 2, reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, is different from the previous embodiment in that a blowing member 300 for blowing cement mixture is provided on the drill body 100 .

[0034] The blowing member 300 includes a plurality of curved panels 301 arranged on the sliding ring 201, one end of the curved panel 301 is wedge-shaped, when the sliding ring 201 rotates synchronously with the drill body 100, the curved panel 301 rotates synchronously, and the curved panel 301 generates wind blowing in all directions when rotating, and guides the cement mixture through the wind force, thereby preventing the cement mixture from spilling to the connection between the drill body 100 and the driving device, and a plurality of guide holes 302 are arranged on the blocking cover 101, and the displacement direction of the cement mixture is guided through the guide holes 302.

[0035] Furthermore, the material of the curved plate 301 is rubber. When the cement mixture enters the curved plate 301 , the rubber material can make the curved plate 301 elastic, thereby reducing the wear of the cement mixture on the curved plate 301 .

[0036] Usage process: When the curved plate 301 rotates, it will generate wind blowing in all directions, and the cement mixture is guided by the wind force to prevent the cement mixture from spilling onto the connection between the drill body 100 and the driving device, so that the user can disassemble the drill body 100 conveniently.

[0037] Example 3, reference Figure 1 to Figure 5 , which is the third embodiment of the utility model, is different from the previous embodiment in that a guide member 400 for guiding the sliding ring 201 is provided on the drill body 100 .

[0038] The guide member 400 includes a branch groove 400a arranged on the drill body 100, and a limit block 400b is arranged on the sliding ring 201. The limit block 400b is slidably arranged on the branch groove 400a. When the limit block 400b slides in the branch groove 400a, the sliding ring 201 on the limit block 400b slides.

[0039] Furthermore, an elastic block 401 is provided on the drill body 100, and the elastic block 401 cooperates with the limit block 400b. The limit block 400b is limited by the elastic block 401, so that both the limit block 400b and the sliding ring 201 are limited.

[0040] Furthermore, a scale 402 is provided on the branch groove 400a. When the limit block 400b slides along the branch groove 400a, the distance between the blocking cover 101 and the end of the drill body 100 can be clearly observed through the scale 402. When the user needs to drill to a certain depth, by observing the scale 402 and then limiting the limit block 400b by the elastic block 401, when the target object drilled by the drill body 100 touches the blocking cover 101, the drilling depth can be obtained.

[0041] Usage process: By adjusting the position of the limit block 400b in the branch groove 400a, the drilling depth of the drill body 100 can be quickly obtained in conjunction with the scale 402. The wind force generated when the curved plate 301 rotates synchronously with the drill body 100 guides the cement mixture to prevent the cement mixture from spilling onto the connection between the drill body 100 and the drive device.
