It is mainly used for on-site detection and rapid analysis of soil pollution. By separating and determining hazardous substances in the soil, it helps users quickly understand the soil pollution status. Traditional separation and determination equipment are operated separately, which is inefficient and sample transfer can easily cause cross-contamination. To address this, a soil hazardous substance separation and determination device is proposed.

[0004] The above technical solution uses a rotating threaded transmission rod to transport soil into a soil separation analyzer for analysis. However, the threaded transmission rod is not equipped with a closed trough, which makes the collected soil easy to scatter from the side, reducing the amount of soil collected at one time and lowering the efficiency of soil testing.

[0018] This utility model provides a soil harmful substance separation and determination device, which has the following beneficial effects:

[0019] (1) This utility model uses a rotating sampling tube inserted into the soil to collect a large amount of soil at one time. When the sampling tube separates the soil, the sampling turning structure can turn the sampling tube to the side of the soil separation tester, so that the soil collected in the sampling tube falls onto the soil separation tester.

A sampling steering structure 2 is rotatably installed on the upper end of the base 1, and a placement frame 4 is provided on the rear end face of the base 1. A soil separation and testing instrument 5 is placed in the placement frame 4.

[0028] like Figure 2 As shown, the sampling steering structure 2 includes a motor 22, which is mounted on one side of the end face of the base 1. The output end of the motor 22 passes through the base 1 and is equipped with a drive gear 21, which is located in an internal groove of the base 1. A driven gear 23 is meshed with one side of the drive gear 21. The driven gear 23 is located in the middle of the base 1, and its output end passes through the base 1 and is equipped with a support frame 24. A moving block 241 is slidably connected to the inner wall of the support frame 24. A cylinder 242 is mounted on the top of the support frame 24, and the output end of the cylinder 242 is connected to the moving block 241. Block 241 is connected, and the outer surface of the movable block 241 is connected to the support plate 31. Both sides of the outer surface of the upright frame 24 are equipped with pushers 243. By rotating the sampling tube 33 that is inserted into the soil, a larger amount of soil can be collected at one time. When the sampling tube 33 separates the soil, the sampling turning structure 2 can turn the sampling tube 33 to the side of the soil separation and testing instrument 5, so that the soil collected in the sampling tube 33 falls onto the soil separation and testing instrument 5. The soil separation and testing instrument 5 measures the harmful substances in the soil, thereby reducing cross-contamination caused by soil transfer.

[0029] like Figure 3 and Figure 4As shown, a soil sampling and testing device 3 is installed at the front end of the sampling steering structure 2. A motor 32 is installed on the upper end of the support plate 31. The output end of the motor 32 passes through the support plate 31 and is connected to the sampling cylinder 33. The soil sampling and testing device 3 includes a support plate 31. A sampling cylinder 33 is rotatably connected to the lower part of the support plate 31. Grooves 331 are opened on the outer surfaces of both sides of the sampling cylinder 33. A pressure plate 332 is slidably connected to the inner wall of the sampling cylinder 33. Connecting blocks 333 are fixedly connected to both sides of the pressure plate 332. The connecting blocks 333 pass through the grooves 331. The connecting blocks 333 at both ends are connected to the pressure plate 332. An arc-shaped connecting plate 334 is fixedly connected to the outer side, and a positioning plate 335 is fixedly connected to the middle of the arc-shaped connecting plate 334. A positioning hole 3351 is opened on the upper inner side of the positioning plate 335. A fixing block 336 is fixedly connected to the upper surface of the sampling cylinder 33. The fixing block 336 is located above the positioning plate 335. Limiting top plates 3361 are fixedly connected to both sides of the upper end of the fixing block 336 for limiting the positioning plate 335. A through hole 3362 is opened at one end of the fixing block 336, and a second positioning hole 3363 is opened on the inner side of the other end of the fixing block 336. A positioning hole 3363 is provided inside the second positioning hole 3363. Magnet 1 3364, fixing block 336 is located on the outer surface of the through hole 3362 and a ring frame 3367 is fixedly connected. A positioning rod 3365 is engaged inside the ring frame 3367. Magnet 2 3366 is located at one end of the inner side of the positioning rod 3365. One end of the positioning rod 3365 is tapered. The tapered positioning rod 3365 can engage with the positioning rod 3365 when the two magnets separate, preventing the positioning rod 3365 from slipping out and falling. The positioning rod 3365 passes through positioning hole 1 3351 and engages with positioning hole 2 3363, so that magnet 2 3366 and magnet 1 3364 are connected. 4. Magnetic attraction: The magnetic attraction between magnet 3366 and magnet 3364 prevents the inserted positioning rod 3365 from falling off, improving the stable positioning effect of the pressure plate 332. By setting the pressure plate 332 inside the sampling cylinder 33, the soil inside the sampling cylinder 33 is squeezed out by pressing, which facilitates material discharge and reduces the problem of soil sticking to the cylinder wall, reducing the cleaning burden of the sampling structure. The pressure plate 332 is connected to the fixing block 336 through the positioning plate 335 and the positioning rod 3365, which can position the pressure plate 332 and prevent it from sliding and sinking.

[0030] The principle of the soil separation analyzer 5 is mainly based on mechanical sieving and physical separation technology. Its core is to separate and analyze soil samples according to aggregates of different particle sizes. This technology enables detailed analysis of soil aggregate structure and helps researchers understand the health status of the soil and the effectiveness of improvement measures.

[0031] This utility model provides a soil hazardous substance separation and determination device. The specific working principle is as follows: The device is moved to the soil to be tested, and the surrounding fixed cones 12 are rotated to penetrate the soil for fixation. During soil separation, the user can activate the cylinder 242 and motor 32 via a control switch, causing the rotating sampling 33 to penetrate the soil for collection. After collection, the user activates the motor 22 via a control switch, driving the drive gear 21 to rotate. Through meshing, the driven gear 23 rotates, causing the stand 24 to rotate, positioning the sampling 33 above the placement frame 4. The user then uses this device to determine the soil hazardous substances. The soil separation and testing instrument 5 for harmful substances is placed in the placement frame 4. Then, the positioning rod 3365 is pulled out, separating magnet 3366 from magnet 3364. The positioning rod 3365 is then engaged by the ring frame 3367. The handles at both ends of the arc-shaped connecting plate 334 can be gripped and pressed down, squeezing out the collected soil, which falls onto the soil separation and testing instrument 5. Plant residues, stones, and other debris are removed. The soil is then sieved, separated, weighed, and images of the soil aggregate distribution on the sieve are captured by a high-definition camera. Image processing algorithms are used to further analyze the microstructural characteristics of the aggregates, such as shape and porosity, to identify harmful substances in the soil.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
