Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of geological drilling, in particular to an anti-blocking alloy drill bit. Background Art
[0002] Drill bits are essential tools in drilling projects. They are manufactured using different materials and technologies, tailored to the geological conditions and drilling requirements, to adapt to various complex drilling environments. Types of drill bits include roller cone bits, diamond bits, carbide bits, and PDC bits. During drilling, due to the unique physical properties of the formation or repeated rotation of the drill bit in the same spot, rock debris and debris can accumulate around the drill bit, causing it to become clogged and difficult to operate. Furthermore, excessive wear of existing drill bits requires complete replacement, which is costly. Utility Model Content
[0003] In order to overcome the above-mentioned shortcomings of the existing problems, the utility model provides an anti-blocking alloy drill bit.
[0004] The technical solution adopted by the utility model to solve its technical problems is: an anti-blocking alloy drill bit, including a drill bit body, a circle of evenly distributed matrix provided at the bottom of the drill bit body, a slag protrusion provided on one side of the bottom of the matrix, and a water trough provided between the lower section of the drill bit body and the matrix. When drilling, the slag crushed by the matrix will be driven by the matrix and collide with the slag protrusion, accelerating the wear of the slag, making it easier for the slag to be subsequently driven by drilling fluid and discharged through the water trough, thereby improving efficiency and effectively preventing the drill bit from being blocked by slag.
[0005] Preferably, the water trough is arc-shaped, and the bending direction of the water trough is consistent with the rotation direction of the drill bit. When the debris is driven and discharged by the drilling fluid, the debris is prevented from directly colliding with the side wall of the water trough, thereby reducing damage and increasing the service life of the drill bit.
[0006] Preferably, a circle of L-shaped fixing blocks are evenly distributed inside the bottom of the drill body, and an inverted L-shaped connecting block used in conjunction with the L-shaped fixing block is fixedly connected to the top of the carcass. The upper part of the L-shaped fixing block is provided with a first bolt for fixing the L-shaped fixing block and the inverted L-shaped connecting block. When the carcass is worn and needs to be replaced, only the carcass needs to be replaced, thereby reducing costs.
[0007] Preferably, a first baffle is provided on one side of the L-shaped fixing block close to the center of the drill body. The first baffle allows the installer to facilitate installation without having to deliberately align the L-shaped fixing block and the inverted L-shaped connecting block.
[0008] Preferably, a second baffle is provided above the side of the inverted L-shaped connecting block away from the center of the drill body, and a second bolt for strengthening the inverted L-shaped connecting block is provided in the upper right corner, and the fixation of the carcass is strengthened by the first bolt and the second bolt.
[0009] The beneficial effect of the present invention is that when the alloy drill bit is working, the crushing efficiency of the crushed slag is effectively improved by the crushing block, the subsequent discharge efficiency is improved, and the crushed slag is prevented from piling up on the drill bit accessories and blocking the drill bit. In addition, the water trough is arc-shaped, and the bending direction of the water trough is consistent with the rotation direction of the drill bit. When the crushed slag is driven and discharged by the drilling fluid, the crushed slag is prevented from directly colliding with the side wall of the water trough, thereby reducing damage and increasing the service life of the drill bit. The carcass is connected to the drill bit body by an L-shaped fixing block and an inverted L-shaped connecting block. When the carcass is worn and needs to be replaced, only the carcass needs to be replaced, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.
[0017] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0018] like Figure 1-4The anti-blocking alloy drill bit shown includes a drill body 1, a circle of evenly distributed matrix 2 is provided at the bottom of the drill body 1, and a slag protrusion 3 is provided on one side of the bottom of the matrix 2. A water trough 4 is provided between the lower part of the drill body 1 and the matrix 2. During drilling, the slag crushed by the matrix 2 will be driven by the matrix 2 and collide with the slag protrusion 3, accelerating the wear of the slag, making it easier for the slag to be subsequently driven by the drilling fluid and discharged through the water trough 4, thereby improving efficiency and effectively preventing the drill bit from being blocked by slag.
[0019] The water trough 4 is arc-shaped, and the bending direction of the water trough 4 is consistent with the rotation direction of the drill bit. When the debris is driven and discharged by the drilling fluid, the debris is reduced from directly colliding with the side wall of the water trough 4, reducing damage and increasing the service life of the drill bit.
[0020] A circle of L-shaped fixing blocks 5 are evenly distributed inside the bottom of the drill body 1, and an inverted L-shaped connecting block 6 used in conjunction with the L-shaped fixing block 5 is fixedly connected to one side of the top of the carcass 2. The upper section of the L-shaped fixing block 5 is provided with a first bolt 9 for fixing the L-shaped fixing block 5 and the inverted L-shaped connecting block 6. When the carcass 2 is worn and needs to be replaced, only the carcass 2 needs to be replaced, thereby reducing costs.
[0021] A first stopper 7 is provided on one side of the L-shaped fixing block 5 close to the center of the drill body 1. The first stopper 7 allows the installer to easily install without having to deliberately align the L-shaped fixing block 5 and the inverted L-shaped connecting block 6.
[0022] A second baffle 8 is provided above the side of the inverted L-shaped connecting block 6 away from the center of the drill body 1, and a second bolt 10 is provided in the upper right corner for strengthening the inverted L-shaped connecting block 6. The first bolt 9 and the second bolt 10 strengthen the fixation of the carcass 2.
[0023] This design is ingenious. When the alloy drill bit is working, the slag protrusions effectively improve the crushing efficiency of the slag, improve the subsequent discharge efficiency, and prevent the slag from accumulating on the drill bit accessories and blocking the drill bit. In addition, the water trough is arc-shaped, and the bending direction of the water trough is consistent with the rotation direction of the drill bit. When the slag is driven and discharged by the drilling fluid, the slag is prevented from directly colliding with the side wall of the water trough, reducing damage and increasing the service life of the drill bit. The carcass is connected to the drill bit body by an L-shaped fixing block and an inverted L-shaped connecting block. When the carcass is worn and needs to be replaced, only the carcass needs to be replaced, reducing costs.
[0024] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
