A second threaded hole 14 is opened at the upper end of the sampling cylinder 5. Scale lines 6 are opened on the outer wall of the sampling cylinder 5.
[0023] Please refer to Figure 1 、 Figure 3 , rotating handles 7 are installed on both sides of the top end of the sampling cylinder 5. The sampling cylinder 5 can be rotated through the rotating handles 7 to rotate and penetrate into the soil. The sampling cylinder 5 is threadedly connected to the positioning bracket 1 through the first threaded hole 4. The depth of excavation of the sampling cylinder 5 can be known in cooperation with the scale lines 6. The blocking block 11 is inserted and engaged with the sampling hole 8. The plug 10 drives the blocking block 11 to block the sampling hole 8 at the bottom end of the sampling cylinder 5 to prevent surface soil from entering the interior of the sampling cylinder 5. The screw 13 is threadedly connected to the sampling cylinder 5 through the second threaded hole 14. By rotating the screw 13, the screw 13 rotates to drive the plug 10 to rise, so that the blocking block 11 is disengaged from the blocking of the sampling hole 8. A limiting strip 9 is installed on the inner wall of the sampling cylinder 5. A sliding groove 12 is opened on the outer wall of the plug 10. The sliding groove 12 is slidably clamped with the limiting strip 9 to limit the plug 10 and avoid the problem that the blocking block 11 cannot be aligned with the sampling hole 8 due to the rotation of the plug 10.
[0024] The sampling device within this utility model includes a positioning bracket 1 and a sampling cylinder 5. A positioning rod 3 is installed at the bottom side of the positioning bracket 1 for plugging and positioning with the ground, and a lifting handle 2 is installed on the upper side of the positioning bracket 1 for lifting the positioning bracket 1 after sampling is completed later.
