Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see the appendix Figure 1 - Appendix Figure 7 An auxiliary testing device for acidic soil includes a U-shaped frame 1, and further includes a connecting plate 3, a sampling component, a liquid addition component, and a mixing and testing component. The connecting plate 3 is horizontally positioned below the horizontal side of the U-shaped frame 1. Two symmetrically arranged hydraulic telescopic rods 2 are vertically installed on the top of the horizontal side of the U-shaped frame 1. The output ends of the two hydraulic telescopic rods 2 are fixedly installed on the top of the connecting plate 3. The sampling component is located at the bottom of the connecting plate 3 and is used to sample the soil to be tested. The liquid addition component is installed at the bottom of the connecting plate 3 and is used to add liquid to the inside of the sampling component. The mixing and testing component is located on the sampling component and is used to mix the sampled soil before testing. The above-mentioned method enables the sampling column 6 to reach the designated position for sampling, and after sampling, the soil and deionized water are mixed. Then, the detection head 27 detects the mixture of soil and deionized water to achieve accurate soil detection.

[0021] Please see the appendix Figure 4 - Appendix Figure 7In a preferred embodiment, the sampling assembly includes a sampling column 6, which is hollow inside and is vertically arranged below the connecting plate 3. A mounting bracket 11 is fixedly sleeved on the surface of the sampling column 6. The mounting bracket 11 is U-shaped and both ends of the mounting bracket 11 are fixedly installed at the bottom of the connecting plate 3. A conical block 9 is fixedly installed at the bottom of the sampling column 6. A through vertical groove 31 is opened at the center of the top of the conical block 9. An insert rod 10 is slidably arranged inside the vertical groove 31. The top end of the insert rod 10 passes through the bottom of the sampling column 6, and the end of the insert rod 10 is conical. Specifically, the electric telescopic rod 4 drives the rotating column 18 and the insertion rod 10 to move upward. At this time, the end of the vertical groove 31 is open. Then, the hydraulic telescopic rod 2 drives the sampling column 6 and the cone block 9 to move downward, so that the soil can enter the sampling column 6 through the vertical groove 31.

[0022] Please see the appendix Figure 1 - Appendix Figure 7 In a preferred embodiment, the mixing detection assembly includes: a rotating column 18, which is vertically disposed inside the sampling column 6. The end of the rotating column 18 is fixedly installed on the top of the insertion rod 10, and the top of the rotating column 18 passes through the top of the sampling column 6. An electric telescopic rod 4 is vertically installed on the top of the connecting plate 3, and the output end of the electric telescopic rod 4 is rotatably installed on the top of the rotating column 18. A rectangular groove 5 is provided on the top of the horizontal side of the U-shaped frame 1. Multiple evenly distributed stirring blades 28 are horizontally fixed on the end surface of the rotating column 18. A belt 14 is rotatably disposed above the sampling column 6. Both ends of the belt 14 are provided with pulleys 15. One pulley 15 is slidably sleeved on the surface of the rotating column 18 through a spline and is also rotatably installed on the top of the sampling column 6. The other pulley 15 is rotatably installed on the top of the horizontal side of the mounting frame 11. A first bevel gear 16 is fixedly installed on the top of the corresponding pulley 15. The first bevel gear 16 is meshed with the second bevel gear 17 on its side. The first rotating rod 30 is fixedly installed at the center of the side of the second bevel gear 17. The end of the first rotating rod 30 away from the second bevel gear 17 passes through the corresponding vertical side of the mounting frame 11, and the surface of the first rotating rod 30 is rotatably installed inside the vertical side of the mounting frame 11. The end of the first rotating rod 30 is fixedly sleeved with the first gear 29. The first rack 12 is vertically installed on the inner side of the corresponding vertical side of the U-shaped frame 1. When the first gear 29 and the first rack 12 are in contact, the first gear 29 and the first rack 12 mesh with each other. The bottom of the connecting plate 3 is vertically fixedly installed with a spring rod 19. The fixed end and the telescopic end of the spring rod 19 are slidably connected by a spline. The telescopic end of the spring rod 19 passes through the top of the sampling column 6. The sampling column 6 is vertically installed with a detection head 27. The end of the telescopic end of the spring rod 19 is fixedly installed at the top of the detection head 27. Preferably, after sampling, deionized water can be automatically added into the sampling column 6, and the insertion rod 10 and the rotating column 18 can be rotated before and after sampling. This 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, ensuring detection efficiency.

[0023] Please see the appendix Figure 1 - Appendix Figure 7 In a preferred embodiment, the liquid addition assembly includes: a water tank 7, which is fixedly installed at the bottom of the connecting plate 3; a connecting pipe 8 is connected to the bottom of the water tank 7; the end of the connecting pipe 8 away from the water tank 7 is connected to the side of the sampling column 6; a sealing plate 20 is slidably disposed inside the water tank 7; deionized water is contained 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 at the top inside the water tank 7; a bidirectional lead screw 22 is rotatably installed inside the water tank 7; the surface of the bidirectional lead screw 22 is connected to the inside of the two horizontal plates 21 by two opposite threads. Each horizontal plate 21 has movable rods 23 rotatably mounted at both ends of its bottom. 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 to the center of the corresponding end of the double-acting screw 22 via a connecting shaft. A one-way bearing 26 is sleeved on the end of the second rotating rod 24 away from the water tank 7. A second gear 25 is sleeved on the outer ring of the one-way bearing 26. 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 come into contact, the second gear 25 and the second rack 13 mesh. Furthermore, the movement of the two horizontal plates 21 causes the four movable rods 23 to move, and the movement of the four movable rods 23 causes 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 and discharge it into the sampling column 6.

[0024] The working principle of this invention is as follows: First, the U-shaped frame 1 is moved to the designated position. Then, the connecting plate 3 is moved downward by the hydraulic telescopic rod 2. The downward movement of the connecting plate 3 causes the components on it to move downward together. The sampling column 6 moves downward, causing 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 soil from entering the interior of the sampling column 6 before reaching the designated position, thus ensuring the accuracy of soil sample collection. In addition, due to the setting of the first rack 12 and the second rack 13, when the first gear 29 moves downward, it will drive the first rotating rod 30, the first bevel gear 16 and the second bevel gear 17 to rotate. 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, which facilitates the conical block 9 to 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. When the designated sampling location is reached, the electric telescopic rod 4 drives the rotating column 18 and the insertion rod 10 to move upward. At this time, the end of the vertical groove 31 is open. Then, the hydraulic telescopic rod 2 drives the sampling column 6 and the cone block 9 to move downward, so that the soil can enter the sampling column 6 through the vertical groove 31. After the sampling is completed, the electric telescopic rod 4 drives the rotating column 18 and the insertion rod 10 to move downward to seal the vertical groove 31. Next, the hydraulic telescopic rod 2 drives the connecting plate 3 and its connecting parts to move upward. Due to the setting of the first rack 12 and the second rack 13, it can be seen that at this time, 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 will drive the double-sided screw 22 to rotate. The rotation of the double-sided screw 22 will drive the two horizontal plates 21 to move. The movement of the two horizontal plates 21 will drive the four movable rods 23 to move. The movement of the four movable rods 23 will drive 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. Then, by rotating the stirring blade 28, the deionized water and the sampled soil can be mixed. It should be noted that when the connecting plate 3 moves downward, the detection head 27 is always at the top of the sampling tube and will not hinder the mixing of deionized water and soil. 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 come into contact with the mixture of soil and deionized water, which can further detect the acidity of the soil and the detection results are accurate, thereby improving the effectiveness of the equipment.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
