The down-the-hole drill with a positioning function for mining and excavation, by rotating the first threaded rod, the first threaded rod moves downward after the internal thread of the collar rotates, and at the same time drives the rotating block to rotate inside the positioning ring, and the positioning ring moves downward to fit the ground under the linkage action of the first threaded rod, thereby positioning the drilling position of the drill barrel, which plays a role in making the device have a positioning function.

[0004] The down-the-hole drill can drive the positioning ring downward to fit the ground by rotating the first threaded rod to determine the position of the drill hole. However, in actual use, since the positioning ring is not fixed, when the first threaded rod is rotated, the positioning ring will deflect horizontally, causing the positioning ring to be non-concentric with the drill barrel, and the position of the drill hole cannot be determined by the positioning ring.

[0005] Therefore, in order to solve the above problems, a down-the-hole drill with a positioning function for mining and excavation is proposed. Utility Model Content
