[0002] With the rapid development of social economy and high-intensity human activities, soil environmental safety issues have attracted widespread attention from the society. "Carrying out soil pollution investigations and understanding the status of soil environmental quality" has become the top priority. Before detecting soil pollution, it is necessary to use a sampling device to conduct on-site soil sampling. The effectiveness of soil sampling will directly affect the accuracy of the detection and analysis results.

[0003] However, after the current direct-push drilling rig removes the drill rod and sampling tube from the soil, it is necessary to perform a pipe-shaving operation on the PVC sampling tube, that is, to cut off a part of the PVC sampling tube to expose the columnar sample, and to cut the longer sample, which is a more cumbersome operation and has shortcomings in use.

[0016] The crawler body adopts the existing well-known crawler vehicle. The control console controls the vertical movement of the horizontal plate 3 and the operation of the rotating motor. The drill bit is installed at the bottom of the drill rod 4. The crawler body 1 drives the long plate 2, the horizontal plate 3, etc. to move. After moving to the site, the crawler body 1 stops moving, and the horizontal plate 3 moves on one side of the long plate 2. The height of the horizontal plate 3 is adjusted and the drill rod 4 is connected through the connector. At this time, the sampling assembly has been installed in the drill rod 4. The control console controls the operation of the rotating motor, and the horizontal plate 4 moves downward, so that the drill rod 4 rotates into the soil. The sampling assembly enters the soil and samples in the soil are sampled. After the sampling is completed, the horizontal plate 3 drives the drill rod 4 to move upward, and the drill rod 4 is taken out of the soil. The connector and the drill rod 4 are disassembled, and then the sampling assembly is taken out of the drill rod 4, and the sample is stored in the sampling assembly.

[0017] Specifically, the long board 2 described in this embodiment has a cavity, and two through grooves are provided on one side of the cavity. The two through grooves are respectively located at the front and rear ends of the long board 2. Two screws 5 are movably installed in the cavity, and two connecting blocks 6 are slidably installed in the cavity. Screw holes are provided on the top surfaces of the connecting blocks, and the screws 5 pass through the screw holes. One end of the connecting block passes through the through groove and is fixedly connected to one side of the horizontal plate 3.

The control console controls the two motors to rotate synchronously, and the two screw rods 5 rotate synchronously, controlling the connecting block 6 to move up and down in the cavity, driving the horizontal plate 3 to move horizontally. During the drilling process, the horizontal plate 3 drives the drill rod to move downward. When removing it, the horizontal plate 3 moves upward to lift the drill rod 4 out of the soil. The usage state is selected according to the use.

[0019] Furthermore, the sampling assembly described in this embodiment includes a first circular ring 7, two half-sleeves 8, multiple placement tubes 9 that are transparent at both ends, and a locking piece.

The external thread of the first circular ring 7 can cooperate with the internal thread of the drill rod 4. A handle 10 is movably installed on the first circular ring 7. The placement tube 9 can be placed in the sleeve formed by the two half-sleeves 8. The locking piece can lock and connect the two half-sleeves 8 after splicing. The first circular ring 7 is connected to the locking piece.

[0020] The two half sleeves 8 can be assembled into a complete sleeve and are located in a drill rod. The placement tube 9 is placed in one half sleeve 8. According to the distance, multiple placement tubes 9 are spaced apart. After the placement is completed, the other half sleeve 8 is assembled with the half sleeve 8. After the assembly is completed, the two half sleeves 8 are locked together by a locking piece. Then the assembled sleeve and the first ring 7 are placed in the drill rod 4. The first ring 7 is rotated by the handle 10, and the first ring 7 is driven to rotate. The first ring 7 drives the assembled sleeve into the drill rod. After the first ring 7 is completely entered into the drill rod, the handle 10 is turned over so that the handle contacts the top surface of the first ring, that is, the handle is no longer in a mutually perpendicular state with the first ring. Then, the drill rod is connected to the output shaft of the rotating motor through the connector to complete the installation of the sampling assembly and the drill rod. Then, the drill rod drives the sampling assembly The component is drilled into the soil. The first way of use is: after drilling is completed, the drill rod is taken out of the soil, and then the drill rod is removed from the connector, the soil on the top of the drill rod 4 is cleaned to expose the handle 10 and the first ring, and then the handle 10 is rotated to drive the first ring to rotate, and the first ring is taken out of the drill rod, and the half sleeve is simultaneously moved out of the drill rod. After the sleeve is taken out, the locking component can be removed from the sleeve, the placement tube is taken out, and then the sample in the placement tube is tested; the second way of use is: after taking out the half sleeve, the entire sleeve can be preserved, that is, the internal sample is not taken out; the third way of use is: after taking the sleeve out of the drill rod, open the half sleeve, and according to the drilling depth, choose to take the placement tubes at different positions during testing, and the samples in the remaining placement tubes can be preserved; during use, different methods of use can be selected as needed.

[0021] Furthermore, the locking member described in this embodiment includes two second rings 11, the inner wall of the second ring 11 is provided with an internal thread, and the outer surfaces of the upper and lower ends of the half sleeve 8 are provided with external threads.

[0036] Step 2: Synchronously control the screw 5 motor to drive the horizontal plate 3 to move downward slowly, and the drill rod 4 drills vertically into the soil.

[0037] Step 3: Soil samples are sequentially placed into the placement cylinders 9 at different depths as the drilling progresses.

[0038] Step 4: After reaching the target depth, the control console reverses the screw 5 motor, and the horizontal plate 3 drives the drill rod 4 to rise, completing the sampling.
