The general idea is as follows:

[0025] In view of the problems existing in the prior art, the present utility model provides a soil component detection sampling device, including a fixed plate 1. The upper surface of the fixed plate 1 is fixedly connected with a support frame 2. Above the fixed plate 1, there is a sampling cylinder 4. Above the sampling cylinder 4, there is a fixed ring 1 8. The right surface of the fixed ring 1 8 is fixedly connected with a clamping block 9. Between the clamping block 9 and the fixed plate 1, there is a screw rod 7 rotatably connected. Inside the sampling cylinder 4, there is a fixed ring 2 17. The lower surface of the fixed ring 2 17 is fixedly connected with a spiral soil drill 15. The upper end of the sampling cylinder 4 is movably sleeved with a bolt 2 12, and the bolt 2 12 is movably sleeved with the fixed ring 2 17. The clamping block 9 is threadedly sleeved with the screw rod 7. The upper surface of the support frame 2 is fixedly installed with a Motor 1 3, and the output shaft of the Motor 1 3 is fixedly connected with the screw rod 7. When sampling is required, place the fixed plate 1 on the sampling ground, and the two pairs of bolts 1 6 arranged on the fixed plate 1 will be inserted into the soil to ensure the stability during the sampling process.

[0026] Two pairs of connecting blocks 5 are fixedly connected to the surface of the fixing plate 1. Bolts 6 are arranged in both pairs of connecting blocks 5. A connecting ring 19 is fixedly connected to the lower surface of the screw soil drill 15. A drill bit 20 is fixedly connected to the lower surface of the connecting ring 19. Two fixing blocks 14 are fixedly connected to the circumferential side of the connecting ring 19. A cutting ring 13 is fixedly connected to the opposite surfaces of the two fixing blocks 14. When the second motor 11 is started, its output shaft will drive the sampling cylinder 4 fixed thereon to rotate together. During the rotation of the sampling cylinder 4, the screw soil drill 15 arranged therein will be driven to rotate together. During the rotation of the screw soil drill 15, the drill bit 20 and the cutting ring 13 will be driven to rotate together. At this time, when the first motor 3 is started, its output shaft will drive the screw rod 7 to rotate together. During the rotation of the screw rod 7, the clamping block 9 sleeved thereon will be driven to move downward. At this time, the sampling cylinder 4 will also move downward accordingly. After the cutting ring 13 and the drill bit 20 break the soil, the screw soil drill 15 will collect it. The sampled soil after complete destruction is more uniform, ensuring the accuracy of the test results. The overall use is convenient, the operation is simple, and the degree of automation is high.

[0027] Two sliders 16 are fixedly connected to the surface of the second fixing ring 17. Two clamping grooves 18 are formed in the inner wall of the sampling cylinder 4. The two clamping grooves 18 are respectively slidably connected to the two sliders 16. A second motor 11 is fixedly installed in the first fixing ring 8. The output shaft of the second motor 11 is fixedly connected to the sampling cylinder 4. After sampling, the bolt 12 is rotated to open the limit between the sampling cylinder 4 and the second fixing ring 17. At this time, the second fixing ring 17 and the screw soil drill 15 fixed thereon can be taken out. At this time, the sampled soil can be collected. The second fixing ring 17 is slidably connected to the inside of the sampling cylinder 4 through the two sliders 16 fixed thereon. During the process of taking out the second fixing ring 17, the two sliders 16 slide in the two clamping grooves 18, and the residual soil inside can be cleaned. The two pairs of bolts 6 can be disassembled, which is convenient for subsequent maintenance and cleaning.

[0028] Working principle:

[0029] When sampling is required, place the fixing plate 1 at the sampling site. The two pairs of bolts I 6 provided on the fixing plate 1 will be inserted into the soil to ensure stability during the sampling process. Start the second motor 11, and its output shaft will drive the sampling cylinder 4 fixed thereon to rotate together. During the rotation of the sampling cylinder 4, the spiral soil drill 15 provided therein will be driven to rotate together. During the rotation of the spiral soil drill 15, the drill bit 20 and the cutting ring 13 will be driven to rotate together. At this time, start the first motor 3, and its output shaft will drive the screw rod 7 to rotate. During the rotation of the screw rod 7, the clamping block 9 sleeved thereon will be driven to move downward. At this time, the sampling cylinder 4 will also move downward accordingly. After the cutting ring 13 and the drill bit 20 break the soil, the spiral soil drill 15 will collect it. The soil sampling after complete destruction is more uniform, ensuring the accuracy of the detection results. The overall use is convenient, the operation is simple, and the automation degree is high. After the sampling is completed, rotate the bolt II 12 to open the limit of the sampling cylinder 4 and the fixing ring II 17. At this time, the fixing ring II 17 and the spiral soil drill 15 fixed thereon can be taken out. At this time, the sampled soil can be collected. The fixing ring II 17 is slidably connected to the sampling cylinder 4 through the two sliders 16 fixed thereon. During the process of taking out the fixing ring II 17, the two sliders 16 slide in the two card slots 18, and the residual soil inside can be cleaned. The two pairs of bolts I 6 can be disassembled, which is convenient for subsequent maintenance and cleaning.
