[0044] Four sets of universal wheels 110 are installed at the bottom of the cart 100, and a U-shaped frame 120 is fixed to the top of the cart 100. An electric push rod 130 is installed on the top of the U-shaped frame 120. A round sleeve 140 is fixed to the end of the movable rod of the electric push rod 130. A first synchronous wheel 2950 is assembled on the upper end of the fixed shaft 220. The surface of the first synchronous wheel 2950 is connected to a meshing first synchronous belt 2960. The inner wall of the first synchronous belt 2960 is away from the first synchronous wheel 2950 and is meshed with a second synchronous wheel 2970. The second synchronous wheel 2970 is meshed with the second synchronous belt 2960. The center of the synchronous wheel 2970 is slidably connected to the long shaft 2980, and the limit strips 2981 are fixed on both sides of the long shaft 2980. A groove that matches the limit strip 2981 is opened in the second synchronous wheel 2970. The bottom end of the long shaft 2980 is fixedly connected to the sampling barrel 2910, and the top end of the long shaft 2980 and the circular sleeve 140 can be rotatably matched through the bearing structure, so that the long shaft 2980 can be driven to descend and rotate at the same time by the electric push rod 130. The surface of the sampling barrel 2910 is fixed with a spiral blade 2911, such as Figure 4 As shown, the spiral blade 2911 on one side of the storage box 380 is spliced ​​with the spiral blade 2911 fixed on the surface of the sampling tube 2910 in sections. The sampling tube 2910 is provided with an empty slot 2912 for collecting soil. Multiple groups of dividing plates 2940 are arranged on both sides of the empty slot 2912. A limiting plate 390 is fixed on the side of the second curved plate 370 away from the first curved plate 360. A card block 3910 is abutted on one side of the limiting plate 390. One end of the card block 3910 slides through one side of the storage box 380, and a square plate 3911 is fixed on the end of the card block 3910. The square plate 3911 is close to the storage box 380. A cylinder 3930 is fixed to one side of the block 3910, and a second spring 3920 is provided at the end of the square plate 3911 away from the cylinder 3930. A shunt tube 3940 is slidably connected to the surface of the cylinder 3930, and an air pipe 3950 is fixed to the end of the shunt tube 3940 away from the cylinder 3930. A contact circular plate 311 is provided directly above the vertical axis 310 and is sleeved on the long axis 2980. A connecting plate 312 fixed to the inner wall of the cart 100 is provided on one side of the contact circular plate 311. An air storage tank 321 is provided between the vertical axis 310 and the movable axis 320, and one end of the air pipe 3950 is connected to the air storage tank 321.

[0045] The staff moves the cart 100 to the location where soil sampling is required, and then starts the servo motor 210 to drive the fixed shaft 220 to rotate, and the fixed shaft 220 drives the first synchronous wheel 2950 to rotate, and the first synchronous wheel 2950 drives the second synchronous wheel 2970 to rotate through the first synchronous belt 2960, and drives the long shaft 2980 to rotate synchronously under the engagement of the limit bar 2981 and the second synchronous wheel 2970, so that the long shaft 2980 drives the sampling cylinder 2910 to rotate, and then Start the electric push rod 130, and drive the sampling tube 2910 to be inserted into the soil through the circular sleeve 140. At this time, the sampling tube 2910 is in a state of rotating and descending. The spiral blade 2911 can make the sampling tube 2910 inserted into the soil more quickly, thereby improving the convenience of the device. When the sampling tube 2910 is inserted into the soil, the soil enters the empty groove 2912 inside the sampling tube 2910, thereby achieving the soil sampling operation, and then the servo motor 210 is reversed to make the solid The fixed shaft 220 drives the ratchet gear 240 to rotate through the first gear 230, so that the ratchet gear 240 drives the reciprocating screw rod 250 to rise and fall. When the reciprocating screw rod 250 descends, it drives the piston rod 260 to squeeze the hydraulic oil inside the piston box 270, so that the hydraulic oil enters the annular groove 291 between the collar 290 and the sampling tube 2910 through the hose 280, and then flows from the annular groove 291 to the connecting pipe 2920, and then enters the four sets of multi-stage telescopic tubes 2930 from the connecting pipe 2920. Under the action of oil pressure, the dividing plates 2940 on both sides are driven to move into the empty groove 2912 until the dividing plates 2940 on both sides are attached to each other, thereby closing the empty groove 2912. At the same time, the soil inside the empty groove 2912 can be cut off to achieve a multi-layer separation effect, ensuring that the soil sample of each layer is representative. The staff can conduct more detailed and accurate analysis of the soil at different layers, thereby improving the accuracy and reliability of the analysis;

[0046] When the soil is layered, the sampling tube 2910 is pulled out of the soil by the electric push rod 130. After the sample tube 2910 is pulled out, the servo motor 210 is turned off and the sample tube 2910 continues to move upward. When the vertical shaft 310 is in contact with the abutting circular plate 311, the vertical shaft 310 will preferentially squeeze the gas inside the gas storage tank 321, so that the gas enters the multi-component manifold 3940 through the air pipe 3950. Under the action of the air pressure, the cylinder 3930 pushes the square plate 3911 to move, so that the square plate 3911 drives the block 3910 to move to release the fixation of the limit plate 390 and squeeze the second spring 3920. Then, the continuous descent of the vertical shaft 310 will drive the moving shaft 320 to descend, so that the moving shaft 320 0 drives the inclined surface pair 330 to move to one side, and under the action of the connecting shaft 340, the other three sets of inclined surface pairs 330 will move, thereby driving the vertical plate 350 to stretch the first spring 351 and move the first curved plate 360, so that the first curved plate 360 ​​pushes the cut-off soil and the second curved plate 370 to move synchronously toward the storage box 380 until the soil is pushed into the storage box 380. Finally, the staff can extract the storage box 380 from the sampling tube 2910, which effectively avoids the mixing of soils at different depths, thereby affecting the accuracy of soil samples during testing, and at the same time improves the efficiency of soil sampling and reduces errors caused by improper sampling.

[0047] Please refer to Figures 5 to 12 The bottom ends of the first curved plate 360 ​​and the second curved plate 370 are both provided with elastic pads 361 , and the bottom ends of the elastic pads 361 are attached to the partition plate 2940 . The first curved plate 360 ​​and the second curved plate 370 are arranged on both sides of the empty slot 2912 .

[0048] By providing the elastic pad 361 , the first curved plate 360 ​​and the second curved plate 370 can more conveniently push the soil in the empty groove 2912 into the storage box 380 when they move.

[0049] Please refer to Figures 13 to 15 Sliders 3960 are fixed on both sides of the storage box 380, a groove 3961 is opened inside the slider 3960, a third spring 3970 is arranged in the groove 3961, a movable plate 3980 is provided on the top of the third spring 3970 for sliding in the groove 3961, a ball 3990 is rotatably connected to the top of the movable plate 3980, and a slot 3991 that matches the ball 3990 is opened inside the sampling tube 2910.

[0050] By pulling the storage box 380, the storage box 380 slides inside the sampling tube 2910. When the storage box 380 moves, the ball 3990 rolls and squeezes the third spring 3970 through the movable plate 3980 until the ball 3990 disengages from the slot 3991, releasing the limit between the storage box 380 and the sampling tube 2910, and then the soil inside the storage box 380 can be taken out.

[0051] Please refer to Figure 1 、 Figure 2 and Figure 16 The stabilizing component 400 includes a support plate 410 fixed to both sides of the collar 290, a rack 420 is fixed to one end of the support plate 410 away from the collar 290, a second gear 430 meshing with it is provided on one side of the rack 420, a base rod 440 is fixed to the center of the second gear 430, a third synchronous wheel 450 is fixed to one end of the base rod 440, a second synchronous belt 460 meshing with it rotates on the surface of the third synchronous wheel 450, a fourth synchronous wheel 470 meshing with it is provided on the inner wall of the second synchronous belt 460 away from the third synchronous wheel 450, a rotating shaft 480 is fixed to the center of the fourth synchronous wheel 470, a rotating plate 490 is fixed to both ends of the rotating shaft 480, and an arc-shaped plug plate 4910 running through both sides of the cart 100 is provided on one side of the top of the rotating plate 490.

[0052] When the sampling tube 2910 descends, the collar 290 is driven to descend, and the collar 290 drives the rack 420 to descend synchronously through the support plate 410, so that the rack 420 drives the second gear 430 to rotate, and the second gear 430 drives the third synchronous wheel 450 to rotate through the base rod 440, and the third synchronous wheel 450 drives the fourth synchronous wheel 470 to rotate through the second synchronous belt 460, so that the fourth synchronous wheel 470 drives the rotating shaft 480 to rotate, so that the rotating shaft 480 drives the arc plug plate 490 through the rotating plate 490. 10 performs an arc motion with the rotating shaft 480 as the center, so that the arc-shaped insert plates 4910 move from both sides of the cart 100 and insert into the soil. The arc-shaped insert plates 4910 can be easily inserted into the soil, providing additional support for the cart 100, and can firmly fix the cart 100 to maintain the stability of the cart 100, thereby preventing the sampling tube 2910 from being inserted too deeply into the soil, causing the cart 100 to be suspended in the air due to loss of ground support, and then there is a risk of tipping over or moving, thereby ensuring that the sampling work is carried out smoothly.

[0053] When in use, the servo motor 210 is started to rotate the sampling tube 2910, and then the electric push rod 130 is started to drive the sampling tube 2910 to be inserted into the soil. When the sampling tube 2910 descends, the arc-shaped insert plate 4910 moves from both sides of the cart 100 and is inserted into the soil. The arc-shaped insert plate 4910 can be easily inserted into the soil, providing additional support for the cart 100, and can firmly fix the cart 100 to maintain the stability of the cart 100, thereby preventing the sampling tube 2910 from being inserted too deep into the soil and causing the cart 100 to be tilted. It will be suspended in the air due to the loss of ground support, and there is a risk of tipping over or moving. To ensure that the sampling work is carried out smoothly, when the sampling tube 2910 is inserted into the soil, the soil enters the empty groove 2912 inside the sampling tube 2910, thereby achieving the soil sampling operation, and multiple groups of dividing plates 2940 are moved into the empty groove 2912 until the dividing plates 2940 on both sides fit together to achieve the closure of the empty groove 2912. At the same time, the soil inside the empty groove 2912 can be cut off to achieve the effect of multi-layer separation. , ensuring that the soil samples of each layer are representative, the staff can conduct more detailed and accurate analysis of the soil at different layers, thereby improving the accuracy and reliability of the analysis. When the soil stratification is completed, the sampling tube 2910 is pulled out of the soil by the electric push rod 130. When the vertical shaft 310 is in contact with the abutting circular plate 311, the gas inside the gas storage tank 321 is squeezed, so that the square plate 3911 drives the block 3910 to move and release the fixation of the limit plate 390. Then the continuous descent of the vertical shaft 310 will make the first arc The curved plate 360 ​​pushes the cut-off soil and the second curved plate 370 to move synchronously toward the side of the storage box 380 until the soil is pushed into the interior of the storage box 380. Finally, the staff extracts the storage box 380 from the interior of the sampling tube 2910, effectively avoiding the mixing of soils at different depths, thereby affecting the accuracy of soil samples during testing. At the same time, it also improves the efficiency of soil sampling and reduces errors caused by improper sampling. The parts not involved in the device are the same as the existing technology or can be implemented using existing technology.
