After the soil collection is completed, the first cylinder 140 drives the sampling tube 150 to be lifted. After the sampling tube 150 is lifted, the staff turns on the second cylinder 211, and the second cylinder 211 drives the push plate 212 to descend. The push plate 212 will descend to push the soil inside the sampling tube 150 out. After being pushed out, the staff collects the soil through the solidification test box 160 for solidification test. Subsequently, the staff turns on the motor 243, and the motor 243 drives the driving gear 244 and the transmission gear ring 242 to rotate. The motor 243 will drive the multiple magnetic strips 250 to rotate, and the multiple magnetic strips 250 will drive the multiple magnetic blocks 230 to rotate. , multiple magnetic blocks 230 drive the mounting seat 221 and the fixing rod 215 to rotate, and the fixing rod 215 will drive the two second rotating rings 214 to rotate between the two first rotating rings 213. At this time, the L-shaped tube 222 rotates at one end of the first spring tube 225, and the installation brush 226 contacts the inside of the sampling tube 150 to rotate, and the water pump 262 is turned on. The water pump 262 supplies water to the first spring tube 225 through the three-way pipe 263, so that the water source enters the annular tube 223 through the L-shaped tube 222, so that the multiple first nozzles 224 rotate to spray water, and then the second cylinder 211 is turned on to drive the first nozzle 224 and the installation brush 226 to perform reciprocating lifting operations, so that the first nozzle 2 24 cooperates with the installed brush 226 to rotate and clean the inside of the sampling tube 150 to improve the cleanliness of the inside of the curing test box 160. At the same time, the three-way pipe 263 supplies water to the external ring tube 247 through the second spring tube 249, and the subsequent water is sprayed to the outer surface of the sampling tube 150 through the second nozzle 248, so that the rotating brush bar 245 cooperates with the second nozzle 248 to clean the outside of the sampling tube 150. After the sampling test is completed, the second connecting rod 500 is pulled outward to allow the ratchet rod 391 to withdraw from the ratchet groove 393, so that the movable bar 330 can be reset, and the reverse rotation of the transmission roller 310 can drive the grounding nail 320 to withdraw from the ground, thereby facilitating subsequent testing.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
