The core drill bit is used as equipment for directly contacting coal and rock to work, and the reasonable design of the drill bit has important significance for rapid and efficient development of engineering. Most of coring bits used at present are simple direct cutting bits, although the use is convenient, the service life of the cutting bit is easy to be reduced and even the cutting bit is damaged due to the frictional heat generated between the cutting bit and a coal rock body in the coring process, and the adopted cooling methods have good effects, but the rotary bit is easy to throw out cooling water to cause a great deal of waste. Meanwhile, if the drill clamping condition occurs in the coring process, the quality of the column to be cored can be influenced, even the breakage of the column is caused, and the working efficiency is also influenced. Improvements in the overall design of the drill bit are needed to address the above-described issues.
Disclosure of Invention
The utility model provides a cooling type core drill with a sleeve, which aims at solving the problems that a core column in the existing core drill is not easy to take out and broken to cause drill sticking, a great amount of heat is generated when the drill is used to cause the damage of the drill to reduce the service life, cooling water is directly sprayed to cause waste and the like.
In order to solve the problems in the background technology, the utility model provides the following technical scheme: a cooling type core drill bit with a sleeve comprises a sleeve, a core taking pipe, a cutting bit and a clamping head; the sleeve is independent of the whole core taking pipe, the inner layers of the upper part and the lower part of the sleeve are provided with thickening layers, and threads are arranged in the thickening layers; the top end of the upper part of the core taking pipe is welded with a clamping head, symmetrical grooves are formed in two sides of the clamping head, a cylindrical water supply channel is formed in the clamping head, and a cutting tool bit is arranged at the bottom end of the lower part of the core taking pipe; and the core taking pipe is provided with a core taking hole.
Preferably, the inner layers of the upper and lower parts of the sleeve are provided with thickening layers, 8 perforations are punched in the thickening layers along the direction parallel to the sleeve, threads are arranged in the thickening layers, and the upper and lower parts of the sleeve are connected with the coring pipe through threads.
Preferably, the outer diameter of the cutting bit is slightly larger than the outer diameter of the coring pipe, and when the sleeve is arranged outside the coring pipe, the outer diameter of the sleeve is exactly the same as the outer diameter of the cutting bit.
Preferably, the coring pipe is provided with 1 pair of symmetrical coring holes for operating the core column clamped in the coring pipe.
Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, 1 pair of symmetrical coring holes are formed in the outer side of the coring pipe, so that when the core column is clamped in the coring pipe and is difficult to take out, the core column can be rapidly and completely taken out through operation at the coring holes; meanwhile, the sleeve is additionally arranged outside the coring pipe, so that the sleeve can prevent cooling water from being sprayed around when the drill bit is used, cooling water can be accumulated between the sleeve and the coring pipe, and when the drill bit is actually drilled for coring, the cooling water accumulated between the sleeve and the coring pipe can continuously flow to the cutting bit through the perforation parallel to the sleeve direction at the thickening layer of the sleeve to cool the cutting bit, and the waste of the cooling water is reduced while the cutting bit is protected.

FIG. 2 is a cross-sectional view and a partial enlarged view of the entire present utility model;
in the figure: 1. a sleeve; 2. taking a core tube; 3. a cutter head; 4. a clamping head; 5. coring holes; 6. a water supply channel; 7. perforating; 8. thickening layers; 9. a groove.
Detailed Description
The utility model is further described below with reference to the drawings and the detailed description.
As shown in fig. 1-2, the following technical scheme is adopted in the specific embodiment of the utility model: a cooling type core drill bit with a sleeve comprises a sleeve 1, a core taking pipe 2, a cutting bit 3 and a clamping head 4; the outer layer of the upper and lower parts of the core taking pipe 2 is provided with threads, the top of the upper end of the core taking pipe 2 is welded with a clamping head 4, two sides of the clamping head 4 are provided with symmetrical grooves 9, an external core taking drilling machine is connected with a core taking drill bit through being clamped in the grooves 9, a cylindrical water supply channel 6 is arranged in the clamping head 4, cooling water is provided for cooling when the drill bit works, the bottom of the lower end of the core taking pipe 2 is provided with a cutting bit 3, the outer diameter of the cutting bit 3 is slightly larger than the outer diameter of the core taking pipe 2, and when the sleeve 1 is arranged outside the core taking pipe 2, the outer diameter of the sleeve 1 is exactly the same as the outer diameter of the cutting bit 3; the sleeve 1 is independent of the whole core taking pipe 2, the inner layers of the upper part and the lower part of the sleeve 1 are provided with threaded thickening layers 8, eight through holes 7 are drilled at the thickening layers 8 along the direction parallel to the sleeve 1, and the threaded sleeve 1 is connected to the outside of the core taking pipe 2 through threaded installation; the coring pipe 2 is provided with a pair of symmetrical coring holes 5 for operating the core column clamped in the coring pipe 2.
The working principle and the using method of the utility model are as follows:
the sleeve 1 is threaded on the outside of the coring pipe 2 prior to operation and the coring bit is maneuvered through the connection of the flutes 9 at the gripping head 4.
When the drill bit is used for coring, cooling water is supplied through the water supply channel 6 to cool the cutting bit 3, and the cooling water flows out through the coring channel on the coring pipe 2 in the water supply process, the flowing cooling water can be accumulated in a gap between the sleeve 1 and the coring pipe 2 due to the existence of the sleeve 1, and at the moment, the through holes 7 parallel to the sleeve 1 direction at the thickening layer 8 can guide the cooling water in the gap into the cutting bit 3 to cool the cutting bit. Because the cooling water and the cutting bit 3 are in direct contact for cooling, the cutting bit 3 can be effectively protected, the service life is prolonged, and meanwhile, the waste of the cooling water is reduced.
If the stem is clamped in the coring pipe 2 after coring, the core column in the coring pipe 2 can be operated and treated through the coring hole 5, so that the quick taking out of the core column is ensured, and the working efficiency is greatly improved.
