A sliding groove 1711 is provided on the surface of the receiving plate 1710, and a stopper 1712 is slidably installed inside the sliding groove 1711. When the pressing plate 11 moves downward, it drives the movable plate 171 to move downward, and the movable plate 171 moves downward to contact the sampling steel pipe 101 to move downward. The pressing plate 11 moves upward and drives the sampling steel pipe 101 to move upward through the clamping device and pulls it out of the soil, so there is no need to prepare a subsequent pipe pulling device, thereby improving the efficiency of soil sampling and reducing the subsequent maintenance cost.

[0026] The upper side of the lifting rod 173 close to the sliding plate 176 is set as bevel surface 1, and the lower side of the stop block 1712 is set as bevel surface 2. A spring 1713 is set between the stop block 1712 and the inner wall of the slide groove 1711. The movable plate 171 moves upward to contact and squeeze the stop block 1712 to move. After the stop block 1712 moves and squeezes the spring 1713, it resets and realizes the limitation of the movable plate 171, thereby fixing the clamping force of the sampling steel tube 101.

The rotating rod 178 is connected to the receiving plate 1710 by a threaded connection. The receiving plate 1710 moves to drive the stopper 1712 to move. The stopper 1712 moves out of contact with the movable plate 171 and releases the limit, thereby loosening the clamping plate 175, which is convenient for the subsequent replacement and disassembly of the sampling steel pipe 101.

[0028] The stabilizing device includes a receiving shaft 181, a guide groove 182 is provided on the surface of the adjusting plate 2, the receiving shaft 181 is clamped in the inside of the guide groove 182, a stabilizing hook 183 is rotatably installed on the circumferential surface of the receiving shaft 181, a stabilizing groove 184 is provided above the supporting plate 1, a stabilizing rod 185 is fixedly installed on the inner wall of the stabilizing groove 184, and a stabilizing block 186 is fixedly installed on the bottom of the inner wall of the stabilizing groove 184. The stabilizing hook 183 and the stabilizing rod 185 can effectively maintain the stability of the adjusting plate 2 during operation, and prevent the adjusting plate 2 from tipping toward the side away from the stabilizing hook 183 due to incorrect operation or accident, and the stabilizing block 186 at the bottom of the inner wall of the stabilizing groove 184 can prevent the adjusting plate 2 from tipping toward the side close to the stabilizing hook 183, thereby further improving the safety of the equipment during operation.

[0029] There are a plurality of stabilizing rods 185 and stabilizing blocks 186, which are evenly distributed inside the stabilizing groove 184. The movement of the adjusting plate 2 drives the stabilizing hook 183 to move. When it moves to a new sampling point, the stabilizing hook 183 is rotated to contact and limit the stabilizing rod 185, thereby changing the position of the adjusting plate 2, facilitating multiple sampling at different positions of the same plot of land, and reducing the error of subsequent soil detection.

[0030] When this embodiment is working: when the sampling steel tube 101 is placed, the clamping plate 175 contacts its surface, and then in the sampling process, when the pressing plate 11 moves downward, it drives the movable plate 171 to move downward, and the movable plate 171 moves downward to contact the sampling steel tube 101 and moves downward, and the sampling steel tube 101 moves downward to contact the ground and squeezes the movable plate 171 to move upward under its action, and the movable plate 171 moves upward to drive one end of the connecting rod 177 to move upward, and one end of the connecting rod 177 moves upward and drives the sliding plate 176 to move in the direction close to the placement tube 16 through the other end, and the sliding plate 176 moves to contact and squeeze the lifting rod 173 to move downward, and the lifting rod 173 moves downward to drive one end of the connecting rod 174 to move downward, and one end of the connecting rod 174 moves downward and drives the clamping plate 175 to move in the direction close to the sampling steel tube 101 through the other end, and the clamping plate 175 contacts the sampling steel tube 101 and clamps it. During this process, the movable plate 171 moves upward to contact and squeeze the stopper 1712 to move. The stopper 1712 moves and squeezes the spring 1713, then resets and limits the movable plate 171, thereby fixing the clamping force of the sampling steel pipe 101. When the sampling is completed, the pressure plate 11 moves upward and drives the sampling steel pipe 101 to move upward through the clamping device and pull it out of the soil, thereby eliminating the need to prepare subsequent pipe pulling devices, thereby improving the efficiency of soil sampling and reducing subsequent maintenance costs. At the same time, when the clamping device needs to be loosened, by rotating the rotating rod 178, the rotating rod 178 rotates through the spiral groove to drive the receiving plate 1710 to move away from the movable plate 171, and the receiving plate 1710 moves to drive the stopper 1712 to move. The stopper 1712 moves out of contact with the movable plate 171 and releases the limit, thereby loosening the clamping plate 175, facilitating the subsequent replacement and disassembly of the sampling steel pipe 101.

[0031] When the soil sampling position needs to be changed, the adjustment plate 2 is moved, and the movement of the adjustment plate 2 drives the stabilizing hook 183 to move. When it moves to a new sampling point, the stabilizing hook 183 is rotated and contacts and limits the stabilizing rod 185 to achieve the change of the position of the adjustment plate 2, which is convenient for multiple sampling at different positions of the same plot of land and reduces the error of subsequent soil detection. At the same time, the stabilizing hook 183 and the stabilizing rod 185 can effectively maintain the stability of the adjustment plate 2 during operation to prevent the adjustment plate 2 from tipping over to the side away from the stabilizing hook 183 due to incorrect operation or accident. At the same time, the stabilizing block 186 at the bottom of the inner wall of the stabilizing groove 184 can prevent the adjustment plate 2 from tipping over to the side close to the stabilizing hook 183, further improving the safety of the equipment process and reducing the safety risks caused by accidents or incorrect operations.
