The output end of the No. 2 cylinder 39 drives the limiting slide 15 and the movable rod 10 to move downward. When the movable rod 10 moves downward, it drives the spiral sampling shaft 21 and the drill bit 22 to move downward. When the movable rod 10 moves, it drives the outer limiting slider 11 to move. The limiting slider 11 slides within the limiting groove 12 to facilitate the extension of the spiral sampling shaft 21 and the drill bit 22, completes the sediment sampling, and collects and processes the sampled sediment of the spiral sampling shaft 21 through the sampling insert 23.

[0029] Among them, one side of the two No. 1 movable slides 13 is fixedly connected with an adjusting support plate 17, and the adjusting support plate 17 is slidably connected to the supporting bottom box 5. A No. 1 cylinder 18 is symmetrically installed inside the supporting bottom box 5. The output end of the No. 1 cylinder 18 is fixedly connected to the adjusting support plate 17. The output end of the cylinder 18 drives the adjusting support plate 17 and the No. 1 movable slide 13 to move. When the No. 1 movable slide 13 moves, it drives the rotating column 8 and the support frame 19 to adjust the height position. When the rotating column 8 adjusts the height, it synchronously drives the outer transmission gear 9 to move. At this time, the transmission gear 9 is still meshed with the gear column 7, and the sampling depth spacing of the two sampling inserts 23 is adjusted. The sampling inserts 23 in two different positions can be adjusted.

[0030] A handle 37 is fixedly connected to the top of the sleeve 1, and the handle 37 is used to lift the entire device to facilitate sampling.

[0031] Among them, a controller 38 is installed on the top of the handle 37, and the motor 16, the No. 1 cylinder 18 and the No. 2 cylinder 39 are all electrically connected to the controller 38. The motor 16, the No. 1 cylinder 18 and the No. 2 cylinder 39 in the device are centrally controlled by the controller 38, thereby improving the safety and efficiency of the use of the device.

[0032] Specifically, when in use, by rotating the tightening bolt 34 outward, and then pulling the pull block 36 and the pull rod 32 outward, the pull rod 32 drives the second movable slide 35 and the limiting block 29 to move outward, and the limiting block 29 leaves the currently fixed limiting slot 3. When the second movable slide 35 moves, the spring 33 is pressed to adjust the position of the telescopic support plate 2 in the sleeve 1, and the pull block 36 is released. The spring 33 resets and drives the second movable slide 35 and the limiting block 29 to reset, and the limiting block 29 re-enters the new limiting slot 3 on one side of the telescopic support plate 2, and then the tightening bolt 34 is rotated inward. The tightening bolt 34 tightens the No. 2 movable slide 35, thereby fixing the position of the limiting block 29, and the limiting block 29 is fixed to the current position. The front limiting card slot 3 is stably fixed, and the position of the telescopic support plate 2 in the sleeve 1 is stably fixed, so that the position of the fixed bottom block 4 and the supporting bottom box 5 can be adjusted, and the positions of the two sampling inserts 23 can be synchronously adjusted. When the sampling depths of two different sampling inserts 23 are required, power is supplied through an external power supply, and the cylinder 18 is started through the controller 38. The output end of the cylinder 18 drives the adjustment support plate 17 and the No. 1 movable slide 13 to move. When the No. 1 movable slide 13 moves, it drives the rotating column 8 and the support frame 19 to adjust the height position. When the rotating column 8 adjusts the height, it synchronously drives the outer transmission gear 9 to move. At this time, the transmission gear 9 is still meshed with the gear column 7, and the output end of the No. 1 cylinder 18 is started. When the movable rod 10, the spiral sampling shaft 21 and the drill bit 22 are synchronously started, so that the movable rod 10, the spiral sampling shaft 21 and the drill bit 22 are synchronously adjusted with the fixed bottom cylinder 20 and the sampling insert 23. After adjusting the two sampling inserts 23 and the drill bit 22 to different depth positions, the No. 2 cylinder 39 is independently started by the controller 38. The output end of the No. 2 cylinder 39 drives the limiting slide plate 15 and the movable rod 10 to move downward. When the movable rod 10 moves downward, it drives the spiral sampling shaft 21 and the drill bit 22 to move downward. When the movable rod 10 moves, it drives the outer limiting slide block 11 to move. The limiting slide block 11 slides within the limiting slide groove 12. By starting the motor 16, the output end of the motor 16 drives the rotating rod 6 and the gear column 7 to rotate. When the gear column 7 rotates, it drives the two meshing transmission gears 9 to rotate. When the transmission gear 9 rotates, it drives the inner rotating column 8 to rotate and adjust. When the rotating column 8 rotates, it drives the inner limiting slide groove 12 to rotate synchronously. When the limiting slide groove 12 rotates an angle, it drives the inner sliding limiting slider 11 and the inner movable rod 10 to rotate. When the movable rod 10 rotates, it drives the spiral sampling shaft 21 and the drill bit 22 to rotate. The position of the sampling insert 23 is fixed. By moving the device downward as a whole, the sampling insert 23 can be inserted into the mud and sand. The extended drill bit 22 is used to drill holes and the spiral sampling shaft 21 is used to sample. The gap adjusted between the drill bit 22 and the sampling insert 23 enters the mud and sand, and enters the sampling insert 23 to complete the sampling.
