[0002] Drilling is a key technology in mining, oil and gas extraction, geothermal development and other fields. It is mainly used for resource exploration, extraction or geological data collection, and drilling equipment is required during extraction operations.

[0003] The "Drilling Equipment for Oil Mining" disclosed in publication number "CN221568422U" includes a hoisting device and a mining platform on which the hoisting device is fixedly installed. A drill rod is connected to the hoisting device. Control boxes are provided on both sides of the upper surface of the mining platform located on the drill rod. Two symmetrically arranged driven gears are rotatably installed inside the control boxes. A drive gear is rotatably installed on the inner wall of the control boxes at the corresponding position of the driven gears. A drive motor is fixedly installed on the outer wall of the control boxes at the corresponding position of the drive gears.

[0004] Traditional drilling equipment has a limited contact area between its bottom and the ground, resulting in limited stability during drilling operations. This leads to instability and wobbling. Furthermore, drilling equipment lacks self-cooling capabilities for the drill bit, causing it to overheat during prolonged operation. High temperatures reduce the drill bit's hardness and cutting performance, impacting drilling efficiency. To address these issues, we have designed a self-cooling drilling system. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a self-cooling drilling device, which solves the problems of limited contact area between the bottom of the device and the ground during operation, resulting in limited stability of the device during mining and drilling operations, and the lack of self-cooling function for the drill bit during operation, leading to high temperatures in the drill bit during long-term mining operations, which in turn reduces the hardness and cutting performance of the drill bit.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a self-cooling drilling device, comprising a base and a lifting seat mounted on the base;

An exhaust fan connected to the air guide slip ring is fixedly installed on one side of the bottom of the lifting seat. A refrigeration tank is fixedly installed on the other side of the bottom of the lifting seat. The front of the refrigeration tank is fixedly connected to the air guide slip ring. A semiconductor refrigeration unit is fixedly installed inside the refrigeration tank. A filter screen is fixedly installed on the back of the refrigeration tank.

[0009] Preferably, both sides of the top of the base are threaded with adjusting screws, and one end of each adjusting screw is rotatably fitted with a limiting sleeve. Rollers are rotatably fitted at equal intervals on the inner wall of the limiting sleeve.

[0010] Preferably, an adjusting motor is fixedly installed above the slide bar, and a threaded rod that is threadedly connected to the lifting seat is fixedly installed at the output end of the adjusting motor.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Example 1

[0027] Please refer to Figures 1 and 5. This embodiment proposes a self-cooling drilling device, including a base 1 and a lifting seat 2 mounted on the base 1. A slide rod 101 is fixedly installed on the outer side of the top of the base 1, and a support sleeve 103 is movably installed on the outer side of the top of the base 1. A telescopic leg plate 104 is slidably installed on one end of the support sleeve 103, and a support foot plate 105 is fixedly installed on the bottom of one end of the telescopic leg plate 104. A sliding sleeve 201 is fixedly installed on the outer wall of the lifting seat 2 and slidably installed on the slide rod 101. A drilling motor 3 is fixedly installed on the top of the sliding sleeve 201. The output end of the drilling motor 3 passes through the lifting seat 2 and is fixedly installed with a transmission rod 301. A drill bit 302 is fixedly installed on the bottom of the transmission rod 301.

[0028] In use, the base 1 supports the bottom of the equipment during operation. A sliding rod 101 is fixedly installed on the outer side of the top of the lifting seat 2. The sliding sleeve 201 of the outer side of the lifting seat 2 is slidably installed on the outer wall of the sliding rod 101. Thus, the sliding sleeve 201 and the sliding rod 101 can limit the path of the lifting seat 2 when it slides up and down. The drilling motor 3 installed on the top of the lifting seat 2 drives the drill bit 302 to rotate through the transmission rod 301. The rotation of the drill bit 302 can perform mining drilling operations. The support sleeve 103 installed on the top of the base 1 is unfolded, and the telescopic leg plate 104 extends inside the support sleeve 103. The support foot plate 105 supports one end of the telescopic leg plate 104. Thus, the cooperation of the unfolded support sleeve 103, the telescopic leg plate 104, and the support foot plate 105 increases the contact area between the equipment and the ground during operation. By increasing the contact area between the equipment and the ground during operation, the stability of the equipment during mining operations is improved, avoiding the equipment from shaking or tipping over during mining operations, and ensuring the safety of the equipment during mining operations.

[0029] Example 2

[0030] Based on Embodiment 1, as shown in Figures 2, 3, 4, and 6, a duct pipe 306 is fixedly installed inside the transmission rod 301, a cooling chamber 304 is opened inside the drill bit 302, a connecting pipe 305 connected to the duct pipe 306 is fixedly installed on the top of the drill bit 302, a duct slip ring 303 is sleeved on the upper part of the outer wall of the transmission rod 301, an exhaust fan 403 connected to the duct slip ring 303 is fixedly installed on one side of the bottom of the lifting seat 2, a refrigeration tank 4 is fixedly installed on the other side of the bottom of the lifting seat 2, the front of the refrigeration tank 4 is fixedly connected to the duct slip ring 303, a semiconductor cooler 401 is fixedly installed inside the refrigeration tank 4, and a filter plate 402 is fixedly installed on the back of the refrigeration tank 4.

[0031] In use, when the drill bit 302 is fixedly installed at the bottom of the transmission rod 301, the two sets of connecting pipes 305 at the top of the drill bit 302 are connected to the two sets of air guide pipes 306 inside the transmission rod 301. The bottoms of the two sets of connecting pipes 305 are respectively connected to the cooling chamber 304 inside the drill bit 302, and the two sets of connecting pipes 305 respectively provide air intake and exhaust to the cooling chamber 304, thereby dissipating the high temperature inside the cooling chamber 304. The air guide pipes 306 can be connected to the rotating end of the connecting pipes 305 and the air guide slip ring 303. The fixed end of the air guide slip ring 303 is fixedly connected to the exhaust fan 403. The exhaust fan 403 can extract and exhaust the hot air inside the cooling chamber 304 through the air guide slip ring 303, the air guide pipes 306, and the connecting pipes 305. When the hot air inside the cooling chamber 304 is extracted, the outside air will pass through the refrigeration tank 4, the air guide slip ring 303, the other set of air guide pipes 306, and the other set of connecting pipes 306. Pipe 305 re-enters its interior, thereby enabling air circulation within the cooling chamber 304 and achieving autonomous heat dissipation for the drill bit 302 during operation. The air guide slip ring 303 can draw in and draw out air from the two sets of air guide pipes 306 when the transmission rod 301 and the drill bit 302 rotate, avoiding the situation where air pipes become entangled during operation. Furthermore, when external air passes through the refrigeration tank 4, its internal semiconductor cooler 401 can cool it down. The cooled gas enters the cooling chamber 304, improving the efficiency and quality of heat dissipation and cooling, preventing the drill bit 302 from experiencing a decrease in hardness and cutting ability due to high temperatures during long-term operation, and ensuring the stability of the drill bit 302 during operation. The filter plate 402 can filter the air entering the refrigeration tank 4, preventing dust and foreign objects in the air from entering the refrigeration tank 4 and causing pollution and blockage.

[0032] As shown in Figure 7, both sides of the top of the base 1 are threaded with adjusting screws 501. One end of each adjusting screw 501 is rotatably mounted with a limiting sleeve 5. Rollers 502 are rotatably mounted at equal intervals on the inner wall of the limiting sleeve 5.

[0033] In use, the two sets of adjusting screws 501 can be rotated to adjust the inward and outward expansion of the two sets of limiting sleeves 5. When the drill bit 302 is working, the inward adjustment of the two sets of limiting sleeves 5 causes the rollers 502 installed inside the limiting sleeves 5 to roll into contact with the outer wall of the transmission rod 301, thereby limiting the rotation of the transmission rod 301, improving the stability of the transmission rod 301 during rotation, and improving the quality of drilling and mining by the drill bit 302.

[0034] As shown in Figure 5, an adjusting motor 6 is fixedly installed above the slide bar 101, and a threaded rod 601 that is threadedly connected to the lifting seat 2 is fixedly installed at the output end of the adjusting motor 6.

[0035] When in use, the adjusting motor 6 can drive the threaded rod 601 to rotate. When the threaded rod 601 rotates, it can drive the lifting seat 2 to move up and down. This allows the drill bit 302 and the transmission rod 301 to descend during equipment operation, thus avoiding the need to adjust and control the drilling speed according to the terrain being mined.

[0036] As shown in Figures 1 and 5, storage slots 106 are provided on the outer side of the top of the base 1, and the storage slots 106 are used in conjunction with the support feet 105.

[0037] When in use, the storage slot 106 can be used for storage and positioning when the telescopic leg plate 104 and the support foot plate 105 are folded and retracted, and it increases the stability of the telescopic leg plate 104 and the support foot plate 105 during storage.

[0038] As shown in Figures 1 and 5, a limit rod 107 is threadedly installed at one end of the top of the support sleeve 103, and the bottom of the limit rod 107 abuts against the top of the telescopic leg plate 104.

[0039] In use, the limiting rod 107 can be lowered by rotating clockwise. When the limiting rod 107 is lowered, its bottom contacts the top of the telescopic leg plate 104, thereby limiting the extension and retraction of the telescopic leg plate 104 and ensuring the stability of the telescopic leg plate 104 during extension and retraction operations.

[0040] As shown in Figures 1, 2 and 5, a tapered rod 102 is fixedly installed on the outer side of the bottom of the base 1.

[0041] When in use, the cone rod 102 can be inserted into the ground when the base 1 is placed, so that the base 1 is placed on the ground for limiting, avoiding displacement of the equipment due to vibration during operation, and ensuring the stability of the equipment during mining operations.

[0042] Working principle: The drilling motor 3 drives the drill bit 302 to rotate through the transmission rod 301, which can perform mining drilling operations. The expansion of the support sleeve 103 and the extension of the telescopic leg plate 104, plus the support of the support foot plate 105, increase the contact area between the equipment and the ground during mining operations, thereby improving the stability of the equipment during mining operations. The exhaust fan 403 extracts and discharges the hot air inside the cooling chamber 304 of the drill bit 302 through the air guide slip ring 303, the air guide pipe 306, and the connecting pipe 305. The external air re-enters the cooling chamber 304 inside the drill bit 302 through the refrigeration tank 4, the air guide slip ring 303, another set of air guide pipes 306, and another set of connecting pipes 305. Thus, the drill bit 302 is cooled down by air circulation. The semiconductor cooler 401 can also cool the incoming air, thereby improving the efficiency and quality of cooling the drill bit 302.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
