This invention discloses a sampling drill bit for a tracked vehicle used in sand and gravel mining, comprising a drill rod, a drill rod sleeve, and a sampling rod inside the drill rod sleeve. The sampling rod is rotatably connected to the drill rod sleeve via a sampling bearing. The upper end of the sampling rod is driven by the output shaft of a sampling motor. The bottom of the sampling rod is provided with a spiral feeding blade for sand and gravel sampling and conveying. A sand discharge port is opened in the middle of the drill rod sleeve, located above the spiral feeding blade. This invention is applicable to the field of mining sampling. By providing a drill rod sleeve and a vibrator on the outside of the drill rod, the drill rod is assisted in its insertion by the vibrator and the needle tip structure of the drill rod sleeve. At the same time, the internal motor drives the spiral feeding blade to drill deeper. Waste samples are discharged through the sand discharge port, and the sample at the target depth is retained in the front end of the drill rod sleeve, enabling sampling at a specific depth. Subsequently, the drill rod is controlled to penetrate deeper into the sampling container and continue to rotate to complete the sample placement. A quick-installation structure for the drill rod is also provided, enabling rapid disassembly and assembly, facilitating replacement and maintenance, and making it more flexible and convenient.
