[0018] This disclosure provides a soil sampling device for testing, comprising a first L-shaped plate, a first linear slide, a second L-shaped plate, a third L-shaped plate, a sampling cylinder, a piston, a round rod, a sampling tube, and a driving component. The first L-shaped plate can be connected to a trolley or carriage, allowing the entire device to move under the drive of the trolley or carriage. The first L-shaped plate includes a through hole in its horizontal wall for the sampling cylinder to pass through. The first linear slide is vertically mounted on the vertical wall of the first L-shaped plate, providing driving force for vertical movement. The second L-shaped plate is mounted on the moving end of the first linear slide and moves up and down under the drive of the first linear slide. The third L-shaped plate is mounted on the moving end of the second linear slide and moves up and down under the drive of the second linear slide. The sampling cylinder is rotatably inserted through the horizontal wall of the second L-shaped plate and can rotate relative to the horizontal wall of the second L-shaped plate.

Then, controlling the second linear slide moves the third L-shaped plate up and down, which in turn moves the cylindrical rod up and down. At this point, the piston pushes the sampling tube out of the sampling tube, eliminating the need for manual removal, saving time and effort, and facilitating soil sampling.

[0036] Combination Figures 1 to 4 As shown, this embodiment of the present disclosure provides a soil sampling device for testing, including a first L-shaped plate 1, a first linear slide 2, a second L-shaped plate 3, a second linear slide 4, a third L-shaped plate 5, a sampling cylinder 6, a piston 7, a round rod 8, a sampling tube 9, and a driving component. The first L-shaped plate 1 can be connected to a trolley or carriage, so that the entire device moves under the drive of the trolley or carriage. The first L-shaped plate 1 includes a through hole in its horizontal wall, through which the sampling cylinder 6 passes. The first linear slide 2 is vertically mounted on the vertical wall of the first L-shaped plate 1 to provide driving force for vertical movement. The second L-shaped plate 3 is mounted on the moving end of the first linear slide 2 and moves up and down under the drive of the first linear slide 2. The second linear slide 4 is vertically mounted on the vertical wall of the second L-shaped plate 3 to provide driving force for vertical movement. The third L-shaped plate 5 is mounted on the moving end of the second linear slide 4 and moves up and down under the drive of the second linear slide 4. The sampling cylinder 6 is rotatably inserted through the horizontal wall of the second L-shaped plate 3 and can rotate relative to the horizontal wall of the second L-shaped plate 3. The sampling cylinder 6 and the through hole are distributed along the same center line, and the outer diameter of the sampling cylinder 6 is smaller than the diameter of the through hole so that the sampling cylinder 6 can pass through the through hole. The piston 7 is installed inside the sampling cylinder 6 and can slide inside the sampling cylinder 6. The round rod 8 is slidably inserted through the center of the top wall of the sampling cylinder 6 and can slide relative to the top wall of the sampling cylinder. The top end of the round rod 8 is rotatably installed on the third L-shaped plate 5 and can rotate relative to the third L-shaped plate 5. The bottom end of the round rod 8 is connected to the piston 7 and is used to drive the piston 7 to move. The sampling tube 9 is inserted inside the sampling cylinder 6 and abuts against the piston 7 for collecting soil. The driving component is installed between the sampling cylinder 6 and the second L-shaped plate 3 to provide driving force and drive the sampling cylinder 6 to rotate relative to the second L-shaped plate 3. The moving range of the first linear slide 2 is approximately equal to the length of the sampling tube 6, and the moving range of the second linear slide 4 is approximately twice the moving range of the first linear slide 2.
[0037] This embodiment of the invention provides a soil sampling device for testing. Activating the drive mechanism causes the sampling tube 6 to rotate relative to the second L-shaped plate 3. Then, controlling the first linear slide 2 causes the first L-shaped plate 1 to move up and down, ultimately driving the sampling tube 6 to move up and down. When the sampling tube 6 is inserted into the ground, soil is collected inside the sampling tube 9. Once the sampling tube 6 is above the ground, the drive mechanism is deactivated, keeping the sampling tube 6 stationary. Then, controlling the second linear slide 4 causes the third L-shaped plate 5 to move up and down, which in turn drives the round rod 8 to move up and down. At this point, the piston 7 pushes the sampling tube 9 out of the sampling tube 6, eliminating the need for manual removal, saving time and effort, and facilitating soil sampling.
[0038] Optionally, combined Figures 1 to 4 As shown, the driving component includes a support rod 10, a motor mounting plate 11, and a drive motor 12. The support rod 10 is vertically mounted on the horizontal wall of the second L-shaped plate 3 to support the motor mounting plate 11. The motor mounting plate 11 is mounted on the top of the support rod 10 to support the drive motor 12. The drive motor 12 is mounted on the motor mounting plate 11, and the axis of the rotating end of the drive motor 12 is parallel to the axis of the sampling cylinder 6 to provide driving force. Driven by the drive motor 12, the sampling cylinder 6 rotates relative to the second L-shaped plate 3.
[0039] In this embodiment, a drive motor 12 is used as a power source to drive the sampling cylinder 6 to rotate relative to the second L-shaped plate 3, which has the advantages of easy control and convenient start-up and reversal.
[0040] Optionally, combined Figure 1 and Figure 4 As shown, the driving component also includes a driving pulley, a driven pulley, and a belt 13. The driving pulley is mounted on the rotating end of the drive motor 12 and rotates under the drive of the motor. The driven pulley is mounted on the outer wall of the sampling tube 6 and is used to drive the sampling tube 6 to rotate. The belt 13 is fitted between the driving pulley and the driven pulley to transmit driving force. The diameter of the driving pulley is smaller than the diameter of the driven pulley.
[0041] In this embodiment, controlling the drive motor 12 to operate drives the active pulley to rotate. The belt 13 then drives the driven pulley to rotate, thereby causing the sampling cylinder 6 to rotate relative to the second L-shaped plate 3. Furthermore, the design of having a smaller diameter for the active pulley than the driven pulley reduces the rotational speed.
[0042] Optionally, combined Figure 1 and Figure 2As shown, it also includes a bearing housing 14 and an angular contact ball bearing 15. The bearing housing 14 is mounted on the horizontal wall of the second L-shaped plate 3 and is sleeved on the sampling cylinder 6.

[0043] In this embodiment, the bearing housing 14 is used to support and mount the angular contact ball bearing 15, and to limit the angular contact ball bearing 15. The angular contact ball bearing 15, which is mounted opposite to the sampling cylinder 6, is used to bear the axial and radial forces, reduce the frictional force on the sampling cylinder 6, and improve the rotational accuracy of the sampling cylinder 6.
[0044] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a sealing cover 16. The sealing covers 16 are respectively installed at both ends of the bearing housing 14, and the sealing covers 16 at both ends abut against the two angular contact ball bearings 15 respectively.
[0045] In this embodiment, the sealing cap 16 serves to provide sealing protection and axially fixes the two angular contact ball bearings 15 to prevent the two angular contact ball bearings 15 from axially moving inside the bearing housing 14.
[0046] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a first retaining ring 17. The first retaining ring 17 is fitted onto the outer wall of the sampling cylinder 6, and the first retaining ring 17 abuts against one of the two angular contact ball bearings 15. The sampling cylinder 6 includes a shoulder located on its outer wall, and the shoulder abuts against the other of the two angular contact ball bearings 15.
[0047] In this embodiment, the sampling cylinder 6 is axially fixed by the shoulder of its outer wall and the first fixing ring 17 to prevent the sampling cylinder 6 from moving axially relative to the two angular contact ball bearings 15.
[0048] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a deep groove ball bearing 18. The deep groove ball bearing 18 is installed between the third L-shaped plate 5 and the round rod 8. The outer ring of the deep groove ball bearing 18 abuts against the third L-shaped plate 5, and the inner ring of the deep groove ball bearing 18 abuts against the round rod 8.
[0049] In this embodiment, the deep groove ball bearing 18 is used to enable the round rod 8 and the third L-shaped plate 5 to rotate relative to each other, thereby enabling the piston 7 to rotate with the sampling cylinder 6, so as to reduce wear and damage between the piston 7 and the sampling cylinder 6.
[0050] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a flexible retaining ring 19. The flexible retaining ring 19 is fitted onto the third L-shaped plate 5 and abuts against the outer ring of the deep groove ball bearing 18.
[0051] In this embodiment of the disclosure, the elastic retaining ring 19 is used to axially fix the deep groove ball bearing 18 to determine the relative position of the deep groove ball bearing 18 and the third L-shaped plate 5.
[0052] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a second retaining ring 20. The second retaining ring 20 is fitted onto the round rod 8 and abuts against the inner ring of the deep groove ball bearing 18.
[0053] In this embodiment of the disclosure, the second fixing ring 20 is used to axially fix the round rod 8 to determine the relative position of the round rod 8 and the deep groove ball bearing 18.
