[0029] The sampling and separation assembly 200 includes a movable plate 230 slidably connected to both sides of the inner wall of the connecting frame 110, a sampling cylinder 280 is rotatably connected inside the movable plate 230, a clamping ring 290 is rotatably connected to the upper end of the curved outer wall of the sampling cylinder 280, an annular groove 291 is provided between the clamping ring 290 and the sampling cylinder 280, an oil pipe 292 connected to the annular groove 291 is provided on both sides of the interior of the sampling cylinder 280, a telescopic tube 293 is provided at one end of the oil pipe 292 away from the annular groove 291, a cutting plate 294 is fixed to the other end of the telescopic tube 293, a piston cylinder 296 is fixed on both sides of the bottom end of the movable plate 230, a piston rod 297 is slidably connected to the inner wall of the piston cylinder 296, and a transverse tube 295 connected to the clamping ring 290 is provided on one side of the piston cylinder 296. A first spring 298 is sleeved on the surface of 97, and a first inclined block 299 is fixed on the side of the piston rod 297 away from the cross tube 295. A second inclined block 2910 fixed to the inner wall of the connecting frame 110 is provided directly below the first inclined block 299. A top plate 120 is installed on the top of the connecting frame 110, and a first motor 210 is fixed to the middle of the bottom end of the top plate 120. A threaded screw 220 is fixed to the output end of the first motor 210, and the threaded screw 220 is rotatably connected to the movable plate 230. A second motor 240 is installed on one side of the top of the movable plate 230, and a driving wheel 250 is fixed to the output end of the second motor 240. A meshing driven wheel 260 is provided on one side of the driving wheel 250, and a circular ring 270 is fixed to the bottom end of the driven wheel 260, and the circular ring 270 is fixed to the sampling tube 280.

[0030] By starting the second motor 240 to drive the driving wheel 250 to rotate, the driving wheel 250 drives the driven wheel 260 to rotate, and the driven wheel 260 drives the sampling cylinder 280 to rotate through the ring 270, and then the first motor 210 is started, so that the first motor 210 drives the movable plate 230 to descend through the screw rod 220, and then the movable plate 230 drives the sampling cylinder 280 and the piston cylinder 296 to descend synchronously, so that the sampling cylinder 280 is inserted into the ground to sample soil. When the movable plate 230 descends to a certain distance, the first inclined block 299 on the side of the piston rod 297 will align with the second inclined block 2910. The first bevel 299 abuts against the first spring 298, thereby causing the piston rod 297 to stretch the first spring 298 to squeeze the oil inside the piston cylinder 296, so that the oil enters the annular groove 291 through the transverse tube 295, and then enters the oil pipe 292 through the annular groove 291. Under the action of pressure, the telescopic tube 293 is extended, thereby pushing the cutting plates 294 on both sides to move closer to the center of the sampling cylinder 280, thereby separating and closing the soil inside the sampling cylinder 280, effectively preventing the soil inside the sampling cylinder 280 from leaking from the bottom due to gravity during the rising process, and ensuring the stability of the soil column shape.

[0031] Please refer to Figure 3 and Figure 4 The top of the piston rod 297 is against the side of the first inclined block 299 and is against a vertical shaft 2920. The vertical shaft 2920 passes through the movable plate 230 and is slidably connected thereto. A round block 2921 is fixed to the curved outer wall of the vertical shaft 2920. A second spring 2923 is provided on the top of the round block 2921. A movable groove 2922 is provided inside the movable plate 230 for the round block 2921 to slide. A round hole 2924 is provided on the top of the first inclined block 299 to cooperate with the vertical shaft 2920.

[0032] When the first inclined block 299 and the second inclined block 2910 abut against each other to drive the piston rod 297 to move, the vertical shaft 2920 will be inserted into the circular hole 2924 on the first inclined block 299 under the action of the second spring 2923, completing the limitation of the piston rod 297 and preventing the cutting plate 294 from moving to both sides during the rising process of the sampling tube 280.

[0033] Please refer to Figure 3 and Figure 5 The horizontal tube 295 passes through one side of the clamping ring 290 and is connected to the annular groove 291.

[0034] By connecting the transverse pipe 295 to the annular groove 291 , the oil in the piston cylinder 296 can flow into the oil passage 292 through the annular groove 291 .

[0035] Please refer to Figure 1 、 Figure 2 and Figure 6The ejection assembly 300 includes a fixed plate 310 installed on the lower ends of both sides of the connecting frame 110, a pulling plate 320 is provided directly above the fixed plate 310, and a plurality of groups of insertion rods 330 passing through the fixed plate 310 are fixed to the bottom end of the pulling plate 320, and a third spring 340 is provided between the pulling plate 320 and the fixed plate 310 and is sleeved on the insertion rod 330. A positioning groove 331 is provided on the top of the base plate 100 to cooperate with the insertion rod 330, and a hinge 350 connected to the base plate 100 is provided at the front end of the connecting frame 110. A push rod 360 is slidably connected to the upper end of the inner wall of the sampling cylinder 280, and the push rod 360 passes through the sampling cylinder 280 and the movable plate 230, and the push rod 360 is slidably connected to the driven wheel 260.

[0036] After the soil sampling is completed, the pull plates 320 on both sides are pulled to disengage the insertion rod 330 from the positioning groove 331, and then contact the fixation between the connecting frame 110 and the base plate 100, and then the connecting frame 110 is changed from a vertical state to a horizontal state through the hinge 350, and then the vertical axis 2920 is pulled to reset the cutting plates 294 on both sides, and finally the push rod 360 is pushed to make the push rod 360 remove the soil inside the sampling tube 280, so that the removed soil is more flat, effectively avoiding the damage to the soil column structure caused by traditional knocking and unloading, so that subsequent personnel can conduct more intuitive inspections.

[0037] When in use, the sampling cylinder 280 is inserted into the ground to sample the soil. When the movable plate 230 drops to a certain distance, the first inclined block 299 abuts against the second inclined block 2910, so that the oil inside the piston cylinder 296 enters the oil pipe 292. Under the action of pressure, the telescopic tube 293 extends, and then the cutting plates 294 on both sides are pushed to the center of the sampling cylinder 280, so as to separate and close the soil inside the sampling cylinder 280, effectively preventing the soil inside the sampling cylinder 280 from leaking from the bottom due to gravity during the rising process, ensuring the stability of the soil column shape. After sampling is completed, the pull plates 320 on both sides are pulled to disengage the insertion rod 330 from the positioning groove 331, and then the connecting frame 110 is changed from a vertical state to a horizontal state through the hinge 350, and then the vertical axis 2920 is pulled to reset the cutting plates 294 on both sides, and finally the push rod 360 is pushed to make the push rod 360 move the soil inside the sampling tube 280 out, thereby making the removed soil more flat, effectively avoiding the damage to the soil column structure caused by traditional knocking and unloading, so that subsequent personnel can conduct more intuitive inspections. The parts not involved in this device are the same as the existing technology or can be implemented using existing technology.
