S2, the battery pack (102) supplies power, three servo drive motors are used, the first servo drive motor (603) drives the rotating disk (601) to rotate along the center of the fixed disk (602), completing the circumferential azimuth rotation action, the second servo drive motor (607) drives the coupling (606) to drive the fixed frame (604) and the extension frame (605) to adjust the direction, completing the angle azimuth adjustment action, reaching the drilling position, the high-definition camera (611) observes, the overall power supply state, the third servo drive motor (703) drives the counterweight shaft (701) to drive the spiral conveying rod (702) to rotate in the forward direction, the drill bit (704) is connected to the sampling layer, and gradually penetrates to the designated position; S3, pressing the forward and reverse electric control switch (609), the connecting cable (610) controls the third servo drive motor (703) to drive the counterweight shaft (701) to drive the spiral conveying rod (702) to rotate in the opposite direction, the hydraulic cylinder (804) drives the hydraulic rod (811) to drive the guide tube (801) to extend and push, the sampled material is gradually broken by the drill bit (704), transported to the guide tube (801) through the spiral conveying rod (702), and enters the storage box (3) through the hose; S4. After drilling for a period of time, the first control valve (404) and the second control valve (407) are opened, and the water pump (808) starts to lift. The water passes through the extension water pipe (405), the delivery water pipe (406) and the access pipe (809) in sequence, circulates through the annular water pipe (806), and is distributed to the access box (807) in sequence. The water passes through the ejector through the ejection hole (810) to clean the spiral delivery rod (702).
