[0016] The working principle and use process of the present invention: In order to facilitate the description and understanding of this working process: it is divided into positioning state and sampling state, and the positioning state and sampling state are described as follows: In the positioning state: the staff drives the first motor to make the main turntable 31 rotate clockwise. Since the bottom surface of the main turntable 31 is fixedly connected to the spline sleeve 319, and the spline sleeve 319 is spline-connected to the spline shaft 318, and the center of the gear column 315 is threadedly connected to the threaded column 316, the bottom end of the threaded column 316 is fixedly connected to the positioning column 8, and the top end of the threaded column 316 is fixedly connected to the spline shaft 318. In addition, since the inner wall of the supply and shift gear ring 311 is rotatably connected to the gear ring 312, the bottom end of the supply and shift gear ring 311 is fixedly connected to the positioning piece 314, and one end of the positioning piece 314 rotates The gear column 315 is connected, the gear column 315 is meshed with the gear ring 312, and the gear column 315 is meshed with the rack 310, so that the multiple racks 310 are synchronously retracted and moved toward the drilling member 2 along the limit groove 313, and the threaded column 316 carries the positioning column 8 to rotate and move downward until the positioning column 8 is screwed into the soil. At this time, the driving of the first motor is stopped, and the motor 7 and the second motor are driven to make the threaded rod 6 rotate clockwise to control the moving platform 4 to move vertically downward, and cooperate with the rotation of the drilling shaft to make the drilling shaft rotate and drill into the soil; In the sampling state: the motor 7 and the second motor are driven to rotate the threaded rod 6 counterclockwise to control the movable platform 4 to move vertically upward, so that the drilling shaft carrying the soil gradually leaves the ground. At this time, the motor 7 and the second motor are stopped, and the first motor is driven to rotate the main turntable 31 counterclockwise. Due to the transmission connection belt 33 between the main turntable 31 and the auxiliary turntable 32, the bottom end of the auxiliary turntable 32 is rotatably connected to the material storage box 35, the bottom end of the auxiliary turntable 32 is fixedly connected to the cleaning ring 34, and the bottom end of the material storage box 35 is fixed. The guide plate 36 is connected and reversed through the above-mentioned working process, so that the soil carried on the drilling shaft is squeezed by the rotation of the cleaning ring 34 and falls onto the guide plate 36 and moves into the storage box 37. Since the top surface of the supply and shift gear ring 311 is fixedly connected to the storage box 37, the storage box 37 is slidably connected to the scraper plate 38, so that multiple racks 310 are synchronously expanded and moved along the limit groove 313 in the direction away from the drilling component 2, and the scraper plate 38 collects the soil stored in the storage box 37 in sections.
