[0031] See also Figure 1-5 The utility model provides a technical solution: an adjustable drill rod for geological prospecting, comprising a mounting seat 1, a first connecting rod 2 is integrally formed at the bottom end of the mounting seat 1, an outer thread is provided on the outer surface of the first connecting rod 2, a second connecting rod 3 is slidably sleeved at the bottom end of the first connecting rod 2, a drill connecting rod 4 is threadedly connected to the inner bottom end of the second connecting rod 3, a locking device is provided at the bottom end of the second connecting rod 3, and the locking device is used to prevent the drill connecting rod 4 from being screwed out of the second connecting rod 3;

[0032] Among them, the locking device includes a connecting ring 5, which is fixedly welded to the bottom end of the second connecting rod 3. The outer diameter of the connecting ring 5 is the same as the outer diameter of the second connecting rod 3, and the inner diameter of the connecting ring 5 is larger than the inner diameter of the second connecting rod 3. Circular grooves 6 are provided on the front and rear sides of the outer surface of the drill connecting rod 4, and reset springs 7 are fixedly installed at the inner bottom ends of the two circular grooves 6. The ends of the two reset springs 7 away from the circular grooves 6 are fixedly welded with clamping rods 8. The ends of the two clamping rods 8 away from the reset springs 7 extend out of the corresponding circular grooves 6, and the ends of the two clamping rods 8 away from the reset springs 7 are both inclined.

[0033] Furthermore, the inner wall of the connection ring 5 is provided with a clamping hole 9 at the position corresponding to the two clamping rods 8, and the two clamping rods 8 are clamped and installed inside the corresponding clamping holes 9;

[0034] Among them, a moving ball rod 18 is slidably installed inside the two clamping holes 9, and the ends of the two moving ball rods 18 that are far away from each other extend out of the outer surface of the connecting ring 5. Springs 19 are fixedly installed on the two moving ball rods 18, and the ends of the two springs 19 that are away from the moving ball rods 18 are fixedly installed on the outer surface of the connecting ring 5.

[0035] Furthermore, a drill bit 10 is fixedly mounted on the bottom end of the drill connecting rod 4 , and a locking washer 11 is fixedly sleeved on the bottom end of the outer surface of the drill connecting rod 4 .

[0036] Furthermore, limiting holes 12 are provided on both the front and rear sides of the outer surface of the second connecting rod 3 , and limiting bolts 13 are slidably installed inside the two limiting holes 12 . The opposite ends of the two limiting bolts 13 are fixedly welded to the front and rear sides of the bottom end of the first connecting rod 2 .

[0037] Furthermore, a rotating groove 14 is provided at the top of the second connecting rod 3, a rotating ring 15 is rotatably installed inside the rotating groove 14, an adjusting tube 16 is integrally formed at the top of the rotating ring 15, an internal thread is provided on the inner wall of the adjusting tube 16, and the adjusting tube 16 is threadedly connected to the first connecting rod 2.

[0038] Furthermore, the outer surface of the adjusting tube 16 is evenly fixed with an anti-slip strip 17. When using the device, the adjusting tube 16 is rotated counterclockwise to drive the first connecting rod 2 to move upward inside the second connecting rod 3, thereby lengthening the length of the drill rod, and two limiting bolts 13 are provided at the bottom end of the first connecting rod 2 to limit the two limiting bolts 13 inside the corresponding limiting holes 12, thereby preventing the first connecting rod 2 from moving out of the second connecting rod 3. The adjusting tube 16 is rotated clockwise to drive the first connecting rod 2 to move downward inside the second connecting rod 3, thereby shortening the length of the drill rod, making it easier to adjust the length of the drill rod. When the drill bit 10 needs to be replaced, the two moving ball rods 18 are pressed to make the two moving ball rods 18 move close to each other, thereby making the two moving ball rods 18 move closer to each other. The ball rod 18 pushes the two clamping rods 8 out of the corresponding clamping holes 9, and then the drill connecting rod 4 is screwed out from the second connecting rod 3 to complete the disassembly, and the new drill bit 10 is threadedly connected to the second connecting rod 3 through the drill connecting rod 4. Since the two clamping rods 8 are arranged at an inclined surface at one end away from the reset spring 7, when the drill connecting rod 4 is screwed into the second connecting rod 3, the second connecting rod 3 pushes the two clamping rods 8 to the corresponding circular groove 6. When the drill connecting rod 4 is completely screwed into the second connecting rod 3, the two clamping rods 8 are just moved to the position of the two clamping holes 9. The two reset springs 7 are extended to drive the two clamping rods 8 to enter the corresponding clamping holes 9, and then the installation is completed. The operation is simple, the drill bit 10 is easy to replace, and the practicality of the device is improved.

[0039] Working principle: When using this device, by rotating the adjusting tube 16 counterclockwise, the first connecting rod 2 is driven to move upward inside the second connecting rod 3, thereby lengthening the length of the drill rod, and by setting two limit bolts 13 at the bottom end of the first connecting rod 2, the two limit bolts 13 are limited inside the corresponding limit holes 12, thereby preventing the first connecting rod 2 from moving out of the second connecting rod 3. Rotating the adjusting tube 16 clockwise can drive the first connecting rod 2 to move downward inside the second connecting rod 3, thereby shortening the length of the drill rod, making it easy to adjust the length of the drill rod.

[0040] When the drill bit 10 needs to be replaced, the two moving ball rods 18 are pressed so that the two moving ball rods 18 move closer to each other, thereby causing the two moving ball rods 18 to push the two clamping rods 8 out of the corresponding clamping holes 9, and then the drill bit connecting rod 4 is screwed out from the inside of the second connecting rod 3 to complete the disassembly.

[0041] The new drill bit 10 is threadedly connected to the second connecting rod 3 through the drill bit connecting rod 4. Since the ends of the two clamping rods 8 away from the reset spring 7 are arranged with an inclined surface, when the drill bit connecting rod 4 is screwed into the interior of the second connecting rod 3, the second connecting rod 3 pushes the two clamping rods 8 to the interior of the corresponding circular groove 6. When the drill bit connecting rod 4 is completely screwed into the interior of the second connecting rod 3, the two clamping rods 8 are just moved to the position of the two clamping holes 9. The two reset springs 7 are extended to drive the two clamping rods 8 to enter the interior of the corresponding clamping holes 9, thereby completing the installation. The operation is simple, it is convenient to replace the drill bit 10, and the practicality of the device is improved.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
