The walking frame 101 supports the first motor 103 to drive the walking wheel 104 to rotate and drive the whole to move to the sampling position, and the reinforcing ribs 102 are used to increase the stability of the walking frame 101;

[0037] In this embodiment: the lifting device includes two symmetrically arranged fixed frames 201, a screw rod 202 is installed in the middle of the fixed frame 201, a lifting frame 203 is installed on the screw rod 202, a second motor 204 is arranged on the top of the screw rod 202, the fixed frame 201 and the second motor 204 are respectively bolted to the walking frame 101, the second motor 204 drives the screw rod 202 to rotate, pushes the lifting frame 203 to drive the supporting plate 301 to move up and down along the fixed frame 201;

[0038] In this embodiment: the classification device includes a supporting plate 301, the supporting plate 301 is made of Q345 steel, a third motor 302 is installed at one end of the supporting plate 301, a gear 303 is installed at the output end of the third motor 302, an electric push rod 304 is installed at one end of the supporting plate 301 away from the third motor 302, the third motor 302 and the electric push rod 304 are respectively bolted to the supporting plate 301, and a baffle 305 is installed at the telescopic end of the electric push rod 304. The baffle 305 is long and made of 45 steel. The supporting plate 301 supports the third motor 302 to drive the gear 303 to engage the gear ring 402 to rotate, and push the rotating frame 401 to rotate under the support of the supporting plate 301, and further supports the extension and contraction of the electric push rod 304, and controls the baffle 305 to control the movement of the sampling rod 403 by blocking the limit platform 404;

[0039] In this embodiment, the sampling device includes a rotating frame 401, which is disc-shaped and connected to the bearing of the support plate 301. A gear ring 402 is installed at the bottom of the rotating frame 401. 16 sampling rods 403 are evenly distributed in the rotating frame 401 and evenly distributed along the circumference of the rotating frame 401. The sampling rods 403 are made of 204 stainless steel. The sampling rods 403 are slidably connected to the rotating frame 401. A limit table 404 is provided at the top of the sampling rod 403.

After the sampling is completed, the second motor 204 drives the screw rod 202 to rotate in the opposite direction, and the sampling rod 403 is pushed down. The movable lifting frame 203 lifts the supporting plate 301, and the sampling rod 403 is pulled out from the ground through the rotating frame 401 and the limit platform 404, and then the third motor 302 drives the gear 303 to engage the gear ring 402 to rotate, and pushes the rotating frame 401 to rotate under the support of the supporting plate 301, and rotates the next sampling rod 403 to the bottom of the baffle 305, so as to facilitate moving to the second sampling point for sampling. When the sampling of all sampling points is completed, the supporting plate 301 supports the electric push rod 304 to retract, driving the baffle 305 to avoid the limit platform 404 of the sampling rod 403, and then the supporting frame drives the rotating frame 401 to move to a position close to the bottom of the sampling rod 403, and then the sampling rod 403 is taken out for replacement, and the classified sampling can be completed.
