When the specified depth is reached, the pull rope 15 is pulled, and the pull rope 15 will pull the baffle 14 to slide along the inclined surface of the sampling head 13, so as to open the bottom of the sampling head 13, and then continue to hammer it down, and then the soil at the required sampling depth will enter the sampling tube 16, so as to complete the soil sampling, so that the soil at different depths can be accurately sampled, so as to reduce the pollution caused by the soil sample, and facilitate the staff to use and study.

When the pull rope 15 is pulled, the pull rope 15 will pull the counterweight block 21 to move. At this time, the pull rope 15 at the bottom of the counterweight block 21 has a certain length, and the baffle 14 does not move. The counterweight block 21 will squeeze the top of the clamping rod 22, so that the clamping rod 22 moves, and the bottom end of the clamping rod 22 is separated from the clamping slot 24. Then continue to lift the pull rope 15, and the pull rope 15 will drive the baffle 14 to move upward, so as to open the bottom of the sampling head 13 for sampling. At the same time, the counterweight block 21 is used to increase the weight at the bottom of the pull rope 15, so that it falls naturally.
[0025] Further, such as Figure 1-2As shown, the sampling rod 11 is slidably connected to a limit seat 31; a bolt 32 is threadedly connected to the side of the limit seat 31; a scale is provided on the surface of the sampling rod 11; when in use, the limit seat 31 can be set to limit the insertion depth of the sampling rod 11, thereby controlling the sampling depth. After adjusting the limit seat 31, the bolt 32 can be tightened so that the end of the bolt 32 fits with the surface of the sampling rod 11, so as to fix the limit seat 31, and the scale is used to assist in adjusting the limit seat 31.
[0026] Further, such as Figure 1-2 As shown, a support ring 41 is fixedly connected to the top of the sampling rod 11; a spring is fixedly connected to the bottom of the support ring 41; a bottom ring 42 is fixedly connected to the bottom end of the spring; a vertical rod 43 is fixedly connected to the top side of the bottom ring 42; the vertical rod 43 passes through the support ring 41 and is slidably connected thereto; the surface of the vertical rod 43 is fixedly connected to the bottom end of the pull rope 15; the bottom ring 42 is slidably connected to the sampling rod 11; when in use, the staff can pull the bottom ring 42 to drive the vertical rod 43 to pull multiple pull ropes 15 to move, thereby controlling the bottom baffle 14 to open, the spring is used to support and push the bottom ring 42 to automatically reset, and the vertical rod 43 is used to guide the pull ring.
[0027] Further, such as Figure 1 and 3 As shown, a cover door 51 is hinged at the bottom of the sampling rod 11; a torsion spring is installed at the hinge of the cover door 51; a pressing rod 52 is hinged on the inner wall of the sampling rod 11; the bottom end of the pressing rod 52 is in contact with the inner wall of the cover door 51; the top of the pressing rod 52 passes through the wall of the sampling rod 11 and is slidably connected thereto; when in use, the sampling tube 16 can be conveniently taken in and out by providing the cover door 51, and the sampling rod 11 can be closed. In order to facilitate the insertion of the sampling rod 11 into the soil, the cover door 51 cannot protrude, and the staff can push the pressing rod 52 to slide into the inside of the sampling rod 11 by pressing, so as to push the cover door 51 open for easy use.
[0028] Further, such as Figure 3 and 4 As shown, a push rod 61 is slidably connected to the top center position of the sampling tube 16; a push piece 62 is fixedly connected to the bottom end of the push rod 61; the push piece 62 is slidably connected to the inner wall of the sampling tube 16; when in use, the staff can screw the sampling tube 16 into the mounting hole by rotating the push rod 61, and the smaller push rod 61 can be easily rotated. At the same time, when performing detection, the soil in the sampling tube 16 can be pushed out by pushing the push rod 61 to drive the push piece 62, which is convenient for detection.
[0029] Further, such as Figure 1As shown, the side of the sampling rod 11 is connected with a pedal 7 through a thread. When in use, when the sampling depth is low, the staff can screw on the pedal 7 through the thread, and then step on the sampling rod 11 into the soil by foot, which is convenient for shallow sampling.
[0030] Working principle: when in use, multiple baffles 14 will close together at the bottom of the sampling head 13 to form a cone, so as to close the bottom of the sampling head 13. Then the staff will insert the bottom of the sampling head 13 into the soil, and then continuously pull the counterweight rod 12 and loosen it to hammer it, so as to drive the sampling rod 11 into the soil. When it reaches the specified depth, pull the pull rope 15, and the pull rope 15 will pull the baffle 14 to slide along the inclined surface of the sampling head 13, so as to open the bottom of the sampling head 13, and then continue to hammer it down, and then the soil at the required sampling depth will enter the sampling tube 16, so as to complete the sampling of the soil, so as to accurately sample the soil at different depths. This can reduce the pollution caused by soil samples and is convenient for staff to use and study. When not in use, the counterweight 21 is located below the top of the clamping rod 22, and multiple baffles 14 form a conical closed bottom of the sampling head 13. The bottom of the clamping rod 22 is inserted into the clamping groove 24 to fix the baffle 14, so that when inserted into the soil, the baffle 14 is not easy to slide obliquely upward to cause the bottom of the sampling head 13 to be opened. When the pull rope 15 is pulled, the pull rope 15 will pull the counterweight 21 to move. At this time, the pull rope 15 at the bottom of the counterweight 21 has a certain length, and the baffle 14 does not move. The counterweight 21 will squeeze the top of the clamping rod 22, causing the clamping rod 22 to move, and the bottom end of the clamping rod 22 is separated from the clamping groove 24. Then continue to lift the pull rope 15, the pull rope 15 will drive the baffle 14 to move up, so as to open the bottom of the sampling head 13 for sampling, and at the same time the counterweight block 21 is used to increase the weight of the bottom of the pull rope 15 to make it fall naturally. By setting the limit seat 31, the penetration depth of the sampling rod 11 can be limited, so as to control the sampling depth. After adjusting the limit seat 31, the bolt 32 can be tightened so that the end of the bolt 32 fits with the surface of the sampling rod 11 to fix the limit seat 31. The scale is used to assist in adjusting the limit seat 31. When in use, the staff can pull the bottom ring 42 to drive the vertical rod 43 to pull multiple pull ropes 15 to move, so as to control the bottom baffle 14 to open. The spring is used to support and push the bottom ring 42 to automatically reset, and the vertical rod 43 is used to guide the pull ring. The cover door 51 is set to facilitate the placement and removal of the sampling tube 16 and close the sampling rod 11. In order to facilitate the insertion of the sampling rod 11 into the soil, the cover door 51 cannot protrude. The staff can push the pressing rod 52 to slide into the inside of the sampling rod 11 to push the cover door 51 open for easy use. The staff can screw the sampling tube 16 into the mounting hole by rotating the push rod 61. The smaller push rod 61 can be easily rotated. At the same time, when testing, the soil in the sampling tube 16 can be pushed out by pushing the push rod 61 to drive the push sheet 62, which is convenient for testing.
