A threaded hole for the screw rod 302 to rotate is provided on the movable plate 304. Since the movable plate 304 is slidably connected to the support frame 301, the screw rod 302 can drive the movable plate 304 to move up and down on the support frame 301.

[0026] See also Figure 1-4The top of the movable plate 304 of the height adjustment component 3 is fixedly provided with a motor 4, and the bottom of the movable plate 304 is rotatably provided with a drilling sampling component, and the motor 4 drives the drilling sampling component to rotate, and the rotating member 5 is rotatably provided at the bottom of the movable plate 304, and the motor 4 drives the rotating member 5 to rotate.

[0027] See also Figure 1-4 , a brake assembly 8 is provided at both the rotating member 5 and the collecting cylinder 6.

[0028] The working principle of this utility model:

[0029] When it is necessary to collect soil, first push the moving clamping rod 801 on the rotating part 5 to deform the spring 802. At this time, the collecting cylinder 6 can be rotatably connected to the rotating part 5. After the rotation connection is completed, the moving clamping rod 801 can be loosened. The elastic force of the spring 802 can pull the moving clamping rod 801 so that the moving clamping rod 801 is engaged with the card slot on the collecting cylinder 6. Then, the drilling cone 7 is installed in the above-mentioned usual manner. Then, the equipment can be moved to a suitable position through the universal wheel 2. Then, the locking structure can be activated to brake the position of the equipment. Then, the motor 1 4 can be started to rotate the drilling sampling assembly. At the same time, the motor 2 303 can be started to drive the screw 302 to rotate, so that the moving plate 304 slides on the support frame 301, so that the drilling cone 7 can drill into the soil. During the rotation of the drilling sampling assembly, the soil will be collected into the collecting cylinder 6 from the rotating inlet 601.

[0030] If the collected soil needs to be taken out, the movable clamping rod 801 is pushed. When the movable clamping rod 801 leaves the clamping slot, the collecting barrel 6 can be rotated to remove the collecting barrel 6 from the rotating member 5, so that the soil can be taken out from the collecting barrel outlet.
