[0038] Preferably, after sampling, deionized water can be automatically added to the interior of the sampling column 6, and the insertion rod 10 and the rotating column 18 can be rotated before and after sampling, which not only facilitates the drilling of the sampling column 6 before sampling, but also allows the soil and deionized water to be mixed after sampling, thereby ensuring detection efficiency.

[0039] Please see attached Figure 1 -Attached Figure 7 In a preferred embodiment, the liquid adding assembly includes: a water tank 7, the water tank 7 is fixedly installed at the bottom of the connecting plate 3, a connecting pipe 8 is installed at the bottom of the water tank 7, and the end of the connecting pipe 8 away from the water tank 7 is installed at the side of the sampling column 6, a sealing plate 20 is slidably arranged inside the water tank 7, deionized water is arranged inside the water tank 7, a water injection pipe is installed on the side of the water tank 7, two symmetrically arranged horizontal plates 21 are slidably installed on the top of the water tank 7, a bidirectional screw 22 is rotatably installed inside the water tank 7, and the surface of the bidirectional screw 22 is connected to the inside of the two horizontal plates 21 respectively through two opposite threads, each Both ends of the bottom of each horizontal plate 21 are rotatably mounted with movable rods 23, and the ends of the four movable rods 23 are rotatably mounted on the top of the sealing plate 20. A second rotating rod 24 is rotatably mounted on the outside of the water tank 7. The end of the second rotating rod 24 is fixedly mounted on the center of the corresponding end of the bidirectional lead screw 22 through a connecting shaft. The end of the second rotating rod 24 away from the water tank 7 is sleeved with a one-way bearing 26, and the outer ring of the one-way bearing 26 is sleeved with a second gear 25. A second rack 13 is vertically mounted on the side of the U-shaped frame 1 corresponding to the vertical side. When the second gear 25 and the second rack 13 are in contact, the second gear 25 and the second rack 13 are meshed;

[0040] Furthermore, the movement of the two horizontal plates 21 drives the four movable rods 23 to move, and the movement of the four movable rods 23 drives the sealing plate 20 to move downward. The downward movement of the sealing plate 20 will squeeze the deionized water inside the water tank 7 from the connecting pipe 8 to the inside of the sampling column 6.

[0041] The working principle of the present invention is as follows: first, the U-shaped frame 1 is moved into the designated position, and then the connecting plate 3 is driven to move downward by the hydraulic telescopic rod 2. The connecting plate 3 moves downward and drives the components thereon to move downward together. The sampling column 6 moves downward and drives the conical block 9 and the insertion rod 10 to move downward together. At this time, the setting of the insertion rod 10 can prevent the soil from entering the sampling column 6 when the designated position is not reached, thereby ensuring the accuracy of soil sample sampling. In addition, due to the setting of the first rack 12 and the second rack 13, the first gear 29 will drive the first rotating rod 30, the first bevel gear 16 and the second bevel gear 17 to rotate when it moves downward. The rotation of the first bevel gear 16 drives the belt 14 and the pulley 15 to rotate. The rotation of the pulley 15 drives the rotating column 18 to rotate. The rotation of the rotating column 18 drives the stirring blade 28 and the insertion rod 10 to rotate, so that the conical block 9 can drill into the soil. Due to the setting of the one-way bearing 26, the second gear 25 will not drive the second rotating rod 24 to rotate through the one-way bearing 26 when it rotates.

[0042] When the designated sampling position is reached, the electric telescopic rod 4 drives the rotating column 18 and the insertion rod 10 to move upwards. At this time, the end of the vertical slot 31 is open, and then the hydraulic telescopic rod 2 drives the sampling column 6 and the conical block 9 to move downwards, so that the soil can enter the sampling column 6 through the vertical slot 31. After the sampling is completed, the electric telescopic rod 4 drives the rotating column 18 and the insertion rod 10 to move downwards to block the vertical slot 31.

[0043] Then, the hydraulic telescopic rod 2 drives the connecting plate 3 and its connecting parts to move upward. Due to the arrangement of the first rack 12 and the second rack 13, it can be seen from the above that the rotation of the first gear 29 will drive the stirring blade 28 to rotate, and the rotation of the second gear 25 will drive the second rotating rod 24 to rotate through the one-way bearing 26. The rotation of the second rotating rod 24 drives the two-way screw 22 to rotate. The rotation of the two-way screw 22 drives the two cross plates 21 to move. The movement of the two cross plates 21 drives the four movable rods 23 to move. The movement of the four movable rods 23 drives the sealing plate 20 to move downward. The downward movement of the sealing plate 20 will squeeze the deionized water inside the water tank 7 from the connecting pipe 8 to the inside of the sampling column 6, and then the deionized water and the sampled soil can be mixed by rotating the stirring blade 28. It should be noted that when the connecting plate 3 moves downward, the detection head 27 is always at the inner top of the sampling tube, which will not hinder the mixing of the deionized water and the soil.

[0044] When the connecting plate 3 moves upward until the first gear 29 and the second gear 25 are no longer in contact with the first rack 12 and the second rack 13, the detection head 27 will be in contact with the mixture of soil and deionized water, and the acidity of the soil can be further detected, and the detection result is accurate, thereby improving the use effect of the equipment.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
