[0023] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The connecting mechanism 11 includes a fixed ring 12. In this embodiment, the fixed ring 12 is fixedly connected to the connecting seat 10. A fixed post 13 is provided at the bottom of the fixed ring 12 and is fixedly connected to the fixed ring 12. A connecting block 14 is provided at the bottom of the fixed post 13 and is fixedly connected to the fixed post 13. A rotating ring 15 is provided at the bottom of the fixed ring 12 and is rotatably connected to the fixed ring 12, allowing it to rotate. A connecting rod 16 is provided at the bottom of the rotating ring 15, which facilitates the replacement and maintenance of the drill rod, thereby improving work efficiency. A sliding groove 17 is provided inside the rotating ring 15. A slider 18 is provided at the top of the connecting rod 16 and is fixedly connected to the connecting rod 16. The sliding groove 17 and the slider 18 are adapted to each other, and the slider 18 is slidably connected to the sliding groove 17. A guide groove 19 is provided inside the fixed ring 12. A guide block 20 is provided on the top of the slider 18 and is fixedly connected to the slider 18. The guide block 20 is slidably connected to the guide groove 19, which allows the connecting rod 16 to move, thereby allowing the sliding block 21 to move. This facilitates the installation, replacement, and maintenance of the drill rod, thereby improving work efficiency. A sliding block 21 is provided on one side of the connecting rod 16 and is fixedly connected to the connecting rod 16. A groove is provided inside the connecting block 14, and a sliding groove 22 is provided inside the connecting block 14. The sliding groove 22 is adapted to the sliding block 21, and the sliding block 21 is slidably connected to the sliding groove 22, which allows the sliding block 21 to move. This facilitates the installation, replacement, and maintenance of the drill rod, thereby improving work efficiency.

[0024] Reference Figure 1 and Figures 3 to 8 The drill rod body 1 has a connecting groove 23 inside, which is adapted to the connecting block 14 and the connecting block 14 is inserted into the connecting groove 23. The connecting groove 23 has a positioning groove 24 inside, which is adapted to the sliding block 21 and the sliding block 21 is inserted into the positioning groove 24. This facilitates the installation of the drill rod, and thus facilitates the installation and disassembly of the drill rod body 1, thereby improving work efficiency. The drill rod body 1 has a telescopic rod 25 inside. In this embodiment, the telescopic rod 25 can extend and retract. The outer surface of the telescopic rod 25 is provided with a spring 26, which can also be other elastic elements. The top of the telescopic rod 25 is provided with a positioning plate 27, which is slidably connected to the drill rod body 1 and can move up and down. The top of the positioning plate 27 is provided with a positioning pin 28, which is fixedly connected to the positioning plate 27. The rotating ring 15 has a positioning hole 29 inside, which is adapted to the positioning pin 28 and the positioning pin 28 is inserted into the positioning hole 29, which can fix the rotating ring 15, thereby fixing the connecting rod 16, fixing the sliding block 21, and fixing the drill rod body 1, which can facilitate the installation and disassembly of the drill rod and improve work efficiency.

[0025] The implementation principle of this embodiment is as follows: The three-headed plow-type spiral drill rod and its chip removal enhancement structure are equipped with a connector 9. When using the equipment, the operator connects the drill rod body 1 to the drill bit through the connector 9. Then, the operator inserts the connecting block 14 into the connecting groove 23. Because the connecting block 14 is inserted into the connecting groove 23, it can be inserted into the connecting groove 23. At this time, the rotating ring 15 will press the positioning pin 28, which will cause the positioning pin 28 to move downward, thereby causing the telescopic rod 25 to retract and the spring 26 to deform. Alternatively, the operator can manually press the positioning plate 27 downward. Then, the operator rotates the rotating ring 15, which drives the slide groove 17 to rotate. Because the slider 18 is slidably connected to the slide groove 17, the slide groove 17 forces the slider 18 to move. The movement of the slider 18 drives the guide block 20 to move. Because the guide block 20 is slidably connected to the guide groove 19, the guide block 20 can move into the guide groove 19. The movement of the slider 18 allows the slider 18 to move, which in turn moves the connecting rod 16. The movement of the connecting rod 16 moves the sliding block 21. Since the sliding block 21 is slidably connected to the sliding groove 22, the sliding block 21 can move and insert into the positioning groove 24. The sliding block 21 is inserted into the positioning groove 24, thus fixing the drill rod body 1 and facilitating its connection. At this time, the positioning pin 28 will be on the same vertical line as the positioning hole 29, causing the spring 26 to lose its external force. The spring 26 then pushes the positioning plate 27 upward. The movement of the positioning plate 27 moves the positioning pin 28, which then inserts into the positioning groove 24, facilitating the installation and removal of the drill rod body 1 and improving work efficiency.

[0026] During operation, the generated waste chips enter the interior of the first through groove 4 and the second through groove 5 through the chip inlet 3. Since the size of the second through groove 5 is smaller than that of the first through groove 4, larger waste chips can be discharged through the first through groove 4, while smaller waste chips can be discharged through the second through groove 5. After the waste chips enter the interior of the first through groove 4, the cutting blade 7 can perform secondary cutting on the waste chips, thereby further reducing the size of the waste chips and preventing them from clogging the first through groove 4. This makes the chip discharge effect of the chip discharge groove 2 smoother. Subsequently, all the waste chips can be discharged through the guide groove 6, thereby improving the chip discharge effect of the equipment.

[0027] Compared with the prior art, the present invention has the following advantages: 1. The three-head plow-type spiral drill rod and its chip removal efficiency enhancement structure are provided with a chip removal groove 2. Larger chips can be discharged through the first through groove 4, smaller chips can be discharged through the second through groove 5, and the cutting blade 7 can perform secondary cutting on the chips, thereby preventing chips from clogging the chip removal groove 2 and thus improving work efficiency. 2. The three-headed plow-type spiral drill rod and its chip removal efficiency enhancement structure are provided with a connecting mechanism 11. By rotating the rotating ring 15, the connecting rod 16 can be moved, which in turn can move the sliding block 21, which can then be inserted into the positioning groove 24. This facilitates the installation and disassembly of the drill rod, as well as its replacement and maintenance, thereby improving work efficiency.

[0028] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
