[0033] In practical applications, the drill pipe of the embodiment of the utility model has the following two usage states:

[0034] State 1, the cutting disc 120 covers the drill tube body 100, the lock buckle 311 and the lock hole 121 are misaligned and locked, at this time, the cutting disc 120 is installed at the end of the drill tube body 100, and can be used for subsequent rotary drilling;

[0035] In state two, the positions of the lock buckle 311 and the lock hole 121 correspond. At this time, the lock buckle 311 can be disengaged from the lock hole 121, so as to disassemble the cutting disc 120 and deal with the mud inside the drill barrel body 100, or by inserting the lock buckle 311 into the lock hole 121 and rotating the locking piece 300, the cutting disc 120 is installed at the end of the drill barrel body 100.

[0036] Among them, in the switching process between the above state 1 and state 2, there are the following operation processes:

[0037] The pressing portion 430 is pressed downward to drive the locking member 300 to rotate along the first direction so that the lock buckle 311 and the lock hole 121 are positioned correspondingly;

[0038] Or the pressing portion 430 is lifted up to drive the locking member 300 to rotate along the second direction, so that the positions of the lock buckle 311 and the lock hole 121 are offset.

[0039] It should be further emphasized that, in the actual construction process, the drill barrel body 100 is connected to the rotary drilling rig through the upper plate assembly 110. When the rotary drilling rig pulls up the entire drill barrel, the end of the rotary drilling rig connection part moves toward the pressing portion 430 to press down the pressing portion 430 to facilitate the removal of the cutting disk 120. On the contrary, in order to assemble the cutting disk 120, the pressing portion 430 needs to be lifted up. Figure 3 A reset mechanism 460 is provided between the first rotating seat 420 and the second rotating seat 440, and the reset mechanism 460 drives the pressing part 430 to be lifted. After the construction personnel cover the cutting disc 120 on the end of the drill pipe body 100 again, the rotary drilling rig moves away from the pressing part 430, so that the first rotating seat 420 and the second rotating seat 440 are close to each other, causing the pressing part 430 to be lifted.

[0040] In summary, the entire driving mechanism for driving the locking member 300 is arranged horizontally on the mounting plate 200. Accordingly, by driving the locking member 300 to rotate through the driving mechanism, the length of the entire drill barrel can be reduced, thereby reducing the volume of the entire drill barrel. The drill barrel can be opened or closed without lifting it too high, thereby improving the convenience of use.

[0041] Preferably, the reset mechanism 460 is a spring, one end of which is fixedly connected to the first rotating seat 420, and the other end of which is fixedly connected to the second rotating seat 440. The elastic force of the spring can be used to lift the pressing portion 430.

[0042] Reference Figure 3 A rotating portion 130 is disposed on the inner side of the lower end of the drill tube body 100 , and the locking member 300 is penetrated through the rotating portion 130 . The locking member 300 can and can only pivot on the rotating portion 130 .

[0043] Specifically, refer to Figure 3In order to avoid the formation of a structural dead point between the first swing rod 431 and the second swing rod 432, a limiting portion 470 is provided on the upper surface of the mounting plate 200, and the limiting portion 470 is located below the first swing rod 431 and the second swing rod 432. When the first swing rod 431 or the second swing rod 432 abuts against the limiting portion 470, the first swing rod 431 and the second swing rod 432 form an angle that bulges outward. This can effectively avoid the first swing rod 431 and the second swing rod 432 from forming a parallel state or a downward bulging state. In addition, in order to further prevent the formation of a dead point structure, a limiting fence 210 is provided on the upper surface of the mounting plate 200, and the pressing portion 430 can be pressed down so that the height of the connection between the first swing rod 431 and the second swing rod 432 is equal to the height of the limiting fence 210, and the first swing rod 431 and the second swing rod 432 form an upward bulging angle. Specifically, the limit fence 210 is arranged along the shape of the ring-shaped mounting plate 200. In actual use, the pressing portion 430 can be pressed down by the rotary drilling rig, so that the height of the connection between the first swing arm 431 and the second swing arm 432 is reduced from a height higher than the limit fence 210 to a height equal to the limit fence 210. In this process, the first swing arm 431 and the second swing arm 432 maintain an upward convex angle, which can prevent them from forming a parallel state or a downward convex angle. The purpose of this is to ensure that during use, the first swing arm 431 and the second swing arm 432 will not form a structural dead point, thereby ensuring the structural stability of the entire drive assembly.

[0044] Preferably, the mounting plate 200 is escalably arranged at the upper end of the drill tube body 100, and the locking member 300 is retractable to match the lifting height of the mounting plate 200 and provide a movement margin. Further, the locking member 300 in the embodiment of the utility model cannot move in the axial direction, and can only rotate around the axis to open or lock the cutting disk 120. For this purpose, the locking member 300 includes a lock core 310 and a sleeve 320. The sleeve 320 is sleeved on the upper end of the lock core 310. A lock buckle 311 is provided at the lower end of the core 310, and the sleeve 320 can and can only slide back and forth along the length direction of the lock core 310. The upper end of the sleeve 320 can pivotally penetrate the mounting plate 200 and is rotatably connected to the mounting plate 200. The upper end of the sleeve 320 is rotatably connected to the third rocker arm 450. Further, a rotating part 130 is provided on the inner side of the lower end of the drill tube body 100, and the locking member 300 is penetrated through the rotating part 130. The locking member 300 can and can only pivot on the rotating part 130.

[0045] Reference Figure 2The end of the drill barrel body 100 and the cutting disc 120 are rotatably connected by a hinge 500. The hinge 500 is fixedly connected to the outer side of the drill barrel body 100 and the edge of the cutting disc 120 respectively. The cutting disc 120 rotates to open the end of the drill barrel body 100 or cover the end of the drill barrel body 100. The cutting disc 120 rotates to open or cover the end of the drill barrel body 100. When the lock buckle 311 passes through the lock hole 121 on the cutting disc 120, so that the cutting disc 120 loses the clamping structure, the cutting disc 120 will swing through the hinge 500 to open the end of the drill barrel body 100, thereby facilitating the subsequent steps and facilitating the discharge of mud residue inside the drill barrel body 100.

[0046] 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, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
