[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

At this time, the linkage hook 12 is hooked on one side of the impact block 6 and drives the impact block 6 to slide along the slide rail 7, while the spring 9 is compressed. As the hydraulic rod 5 drives the linkage hook 12 to continue to move, when the inclined structure at one end of the linkage hook 12 contacts one end of the trigger rod 10, the trigger rod 10 causes the linkage hook 12 to flip. At this time, the linkage hook 12 is separated from the locking part of the impact block 6, and then the compressed spring 9 is released, and pushes the impact block 6 to slide in the slide groove of the slide rail 7, thereby causing the impact block 6 to hit one end of the drill bit 3. At this time, the drill bit 3 can break the hard materials in the ground, so that the pile head structure has an active breaking structure and function, and the functionality and practicality are effectively improved.

[0019] Furthermore, a reset spring 8 is externally sleeved on one end of the drill bit 3, and one end of the reset spring 8 rests on the inner end surface of the pile body 1. The upper end of the pile body 1 is integrally connected with a connecting seat 2, wherein the reset spring 8 can be used to provide the drill bit 3 with a reset structure to ensure that the drill bit 3 can perform repeated breaking operations.

[0020] Working principle: When in use, the pile body 1 is first installed on one end of the drill rod through the connecting seat 2, and the drilling operation can be carried out at this time. When encountering hard materials buried in the ground during the drilling process, the hydraulic rod 5 is started, and the contraction of the hydraulic rod 5 drives the connecting bracket 11 and the linkage hook 12 to move along the axial direction of the hydraulic rod 5. At this time, the linkage hook 12 is hooked on one side of the impact block 6, and drives the impact block 6 to slide along the slide rail 7, and at the same time, the spring 9 is compressed. As the hydraulic rod 5 drives the linkage hook 12 to continue to move, when the inclined structure at one end of the linkage hook 12 contacts one end of the trigger rod 10, the trigger rod 10 causes the linkage hook 12 to flip. At this time, the linkage hook 12 is separated from the locking part of the impact block 6, and then the compressed spring 9 is released, and pushes the impact block 6 to slide in the slide groove of the slide rail 7, so that the impact block 6 hits one end of the drill bit 3. At this time, the drill bit 3 can break the hard materials in the ground. When the impact block 6 is separated from the drill bit 3 again, the drill bit 3 is reset by the reset spring 8.
