The downward movement of the sealing plate pushes the soil inside the sampling drill tube out, making it easier to collect and test the soil. At the same time, the upward movement of the rotating rod drives the sampling frame to move toward the bottom of the sampling drill tube, and the pushed-out soil is pushed onto the sampling frame through the sealing plate, making it easier to recover and test the soil and improving work efficiency.

[0022] (3) In the present invention, the upward movement of the trapezoidal plate will drive the square frame to move upward, and the upward movement of the square frame will increase the height of the sampling frame to prevent the soil from sliding out from around the sampling frame when the soil is pushed out, resulting in soil shortage and affecting the detection efficiency. The contact between the protrusion and the short plate will generate vibration to prevent the soil from piling up too high. The vibration will enable the soil to be spread flat on the sampling frame, thereby improving the detection efficiency of the soil. BRIEF DESCRIPTION OF THE DRAWINGS

The downward movement of the sealing plate 182 will push out the soil inside the sampling drill barrel 10, so as to facilitate the collection and detection of the soil.

[0037] A connecting seat 184 is fixedly installed on one side of the sliding frame 12 close to the spiral rod 4, a sliding rail 187 is fixedly installed on the surface of the base 1, a sampling frame 186 is slidably installed on the inner wall of the sliding rail 187, a rotating rod 185 is rotatably installed on the surface of the sampling frame 186, and one end of the rotating rod 185 away from the sampling frame 186 is rotatably installed on the surface of the connecting seat 184, and the pushed-out soil is pushed onto the sampling frame 186 through the sealing plate 182, which facilitates the recovery and detection of the soil and improves work efficiency.

[0038] A No. 2 torsion spring is arranged between the rotating rod 185 and the connecting seat 184, and the rotating rod 185 is reset by the No. 2 torsion spring. A No. 4 spring is arranged between the slide rail 187 and the sampling frame 186, and the sampling frame 186 is reset by the No. 4 spring.

[0039] The protective device includes a square frame 191, a trapezoidal plate 192, a connecting frame 193 and a pulley 194. A groove is provided on the top of the sampling frame 186. The square frame 191 is slidably installed on the inner wall of the groove. The trapezoidal plate 192 is fixedly installed on a side of the square frame 191 close to the slide rail 187. The connecting frame 193 is fixedly installed on the top of the slide rail 187. The pulley 194 is rotatably installed on the inner wall of the connecting frame 193.

[0042] When the present embodiment is working, the long rod 181 is driven downward by the downward movement of the sampling drill tube 10, and the downward movement of the long rod 181 will drive the sealing plate 182 to move downward. When the soil enters the sampling drill tube 10, the sealing plate 182 will be pushed to move upward. The upward movement of the sealing plate 182 will drive the long rod 181 to move upward.

When the sampling is completed, the driving device 3 reverses to drive the sampling drill tube 10 to move upward and reset, and the movable frame 5 will also move upward and drive the semicircular plate 7 to move upward. The upward movement of the semicircular plate 7 will drive the sampling drill tube 10, the sealing plate 182, the long rod 181 and the circular plate 183 to move upward. The circular plate 183 moves upward and contacts the support plate, and the reverse force will push the circular plate 183 to move upward. The plate 183, the long rod 181 and the sealing plate 182 move downward, and the sealing plate 182 moves downward to push out the soil inside the sampling drill tube 10, which is convenient for collecting and testing the soil. At the same time, the sliding frame 12 will drive the connecting seat 184 to move downward during the downward movement, and the connecting seat 184 will push the rotating rod 185 and the sampling frame 186 to move away from the spiral rod 4. When the moving frame 5 is reset, the sealing plate 182 pushes the soil out, and the connecting seat 184 will pull the rotating rod 185 to move upward.

[0043] The sampling frame 186 moves toward the bottom of the sampling drill tube 10, driving the square frame 191 to move toward the bottom of the sampling drill tube 10. The square frame 191 moves toward the bottom of the sampling drill tube 10, driving the trapezoidal plate 192 to move toward the bottom of the sampling drill tube 10. The trapezoidal plate 192 moves toward the bottom of the sampling drill tube 10 and contacts the pulley 194. The pulley 194 pushes the trapezoidal plate 192 to move upward. The upward movement of the trapezoidal plate 192 drives the square frame 191 to move upward. The upward movement of the square frame 191 increases the height of the sampling frame 186 to prevent the soil from falling from the sampling frame 186 when the soil is pushed out. The sampling frame 186 slides out on all sides, resulting in a lack of soil, which affects the detection efficiency. At the same time, when the sampling frame 186 moves away from the bottom of the sampling drill tube 10, it will drive the trapezoidal plate 192 to move away from the bottom of the sampling drill tube 10. The trapezoidal plate 192 moves away from the bottom of the sampling drill tube 10 and drives the short plate 197 away from the bottom of the sampling drill tube 10.
