[0051] Reference Figure 8 and Figure 9 As shown, when the soil sample inside the sampling port 13 is cleaned, the adjusting bolt 62 is rotated and screwed into the 65 and threaded hole 61, and then the end of the adjusting bolt 62 moves horizontally along the inside of the threaded groove 64 and the threaded hole 61, at which time the adjusting bolt 62 is separated from the inside of the threaded groove 64 during the movement, at which time the cup receiving ring 52 loses the locking effect between the two supports 51, and rotating the cup receiving ring 52 adjusts its posture between the two supports 51, and the outside of the cup receiving ring 52 rotates synchronously along the outside of the limiting column 63 during the adjustment, then the adjusting bolt 62 is screwed again with the threaded groove 64 to keep the distance of the adjusted cup receiving ring 52 stable, which can prevent the soil sample inside the sampling port 13 from falling into the inside of the cup receiving ring 52 or the abutting arc bracket 53 during cleaning.

[0052] Working principle:

[0053] In use;

[0054] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when it is necessary to sample and detect saline-alkali soil, first, the spiral soil auger 12 rotates inside the sampling and detecting cylinder 21 and the drill cylinder 1, at this time, the end of the spiral soil auger 12 is in advance in contact with the soil, then the end of the spiral soil auger 12 is used to cut the contacted soil into the soil, followed by the telescopic cylinder 11 telescoping downward to push the spiral soil auger 12 to move downward synchronously, so that the rest of the spiral soil auger 12 moves to the depth of the soil, during the rotation of the spiral soil auger 12, the blade edge cuts into the soil, stripping the soil block (including the saline-alkali soil block, salt crust) from the original position, and pushing it upward along the spiral surface of the blade, and crushing the soil sample of the spiral soil auger 12 through the sampling and detecting assembly 2, and continuing to transport upward along the blade of the spiral soil auger 12, until being discharged from the inside of the sampling port 13, so that the soil completes the continuous process of “cutting-crushing-transporting” during sampling and detection.

[0055] Referring to Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, when the spiral soil auger 12 lifts the extracted soil upward along the inside of the sampling and detecting cylinder 21 to the vicinity of the sampling port 13, the second servo motor 36 drives the directional rod 34 to rotate along the inside of the drill cylinder 1 and the sampling port 13, then drives the two push blades 35 to rotate synchronously, at this time, the two push blades 35 rotate in shear with the soil in contact with them, pushing the soil along the spiral surface of the two push blades 35 to the tearing ring 32, the crushing mill seat 33 and the tearing ring 32, followed by the crushing mill seat 33 and the tearing ring 32 rotating synchronously along the inside of the tearing ring 32 under the rotation of the directional rod 34, for tearing the soil inside, and when it is necessary to sample and detect the soil layer by layer and to clean the soil sample remaining in the sampling port 13 after sampling, the stable sampling assembly 4 removes the residual soil sample inside the sampling port 13 and the horizontal pushing and discharging assembly 3, so that each layer of sample only contains the soil of the current depth, ensuring that the detection data can truly represent the saline-alkali characteristics of the layer, and providing a reliable basis for subsequent soil layering treatment.

[0056] Referring to Figure 8 and Figure 9When the sampling cup is inserted into the cup receiving ring 52, the side of the abutting arc bracket 53 will be in contact with the sampling cup, and the abutting arc bracket 53 will be forced to move into the arc groove 54, and then the concentric groove 55 will move along the contact column 57, and the reset spring 56 will be compressed between the concentric groove 55 and the contact column 57, and in this process, the outside of the sampling cup will slowly move downward along the side of the abutting arc bracket 53 until the cup opening is in contact with the top of the cup receiving ring 52, at which time the cup receiving ring 52 will hold the sampling cup, and then the reset spring 56 will exert a pushing force on the side of the concentric groove 55 to move the abutting arc bracket 53 along the arc groove 54 to the outside of the sampling cup, thereby ensuring that the sampling cup remains stable in the cup receiving ring 52, and through this structure, the sampling cup can stably collect the soil samples discharged from the inside of the sampling port 13, and ensure that the soil samples can truly reflect the actual condition of the soil during detection.
