Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a soil pollution investigation and detection device includes a processing table 1. An electric actuator 11 is fixedly connected to the bottom of the processing table 1. A support base 12 is fixedly connected to the bottom of the electric actuator 11. A cylinder 13 is fixedly connected to the top of the processing table 1. A base plate 14 is fixedly connected to the output end of the cylinder 13. A motor 15 is fixedly connected to the top of the base plate 14. A support sleeve 16 is fixedly connected to the output end of the motor 15. A sampling tube 17 is provided on the support sleeve 16. A drill bit 18 is fixedly connected to the bottom of the support sleeve 16. A sampling port 19 is opened inside the drill bit 18. The sampling port 19 is connected to the sampling tube 17. A detection device body 101 is fixedly connected to the top of the processing table 1. The processing table 1 is placed around the soil to be sampled, and then the support bases 12 at the four corners are fixed at the sampling positions. At this time, the overall height of the processing table 1 can be adjusted by starting the electric actuator 11. Then, the motor 15 can be started. After starting the motor 15, the motor 15 will drive the support sleeve 16 to start rotating. The drill bit 18 rotates along with the soil sample. After aligning the drill bit 18 with the soil to be sampled, the cylinder 13 is activated. The cylinder 13 then drives the drill bit 18 to move downwards. The drill bit 18 moves downwards while rotating. After the drill bit 18 contacts the soil, it continues to penetrate deeper. When it encounters branches or gravel, the drill bit 18 will drill through them. After penetrating into the soil, the sampling port 19 will collect a sample of the soil to be collected. Finally, the sample is transferred through the sampling port 19 to the sampling tube 17. The sampling tube 17 can be removed from the support sleeve 16 and then placed on the detection device body 101 for testing. By adding the drill bit 18, the branches and gravel attached to the surface of the soil can be removed during soil collection. At the same time, the addition of the cylinder 13 and the motor 15 allows the drill bit 18 to rotate and move simultaneously. The cylinder 13 allows the drill bit 18 to sample soil at different depths, further improving the soil testing speed.
[0026] like Figures 1 to 4 As shown, a support ring 21 is fixedly connected to the outer wall of the drill bit 18; a spring telescopic rod 22 is fixedly connected to the bottom of the support ring 21; multiple blades 2 are fixedly connected to the bottom of the spring telescopic rod 22; when it is necessary to remove and test the entire soil, the spring telescopic rod 22 can be slid, and then the spring telescopic rod 22 will drive the blades 2 to move up and down. After the blades 2 are moved to the bottom of the drill bit 18, the motor 15 is started, and the motor 15 will drive the blades 2 to start rotating. When the blades 2 come into contact with the soil, they will cut and remove the soil as a whole; by adding blades 2, the soil can be completely removed, and the soil profile can be inspected as a whole, increasing the integrity of the soil inspection by the inspection device body 101 and widening the working range of the inspection device body 101.
[0027] like Figures 1 to 4As shown, a support frame 31 is fixedly connected to the side wall of the support base 12; a sliding groove 33 is provided inside the support frame 31; a cleaning scraper 3 is slidably connected inside the sliding groove 33; a sliding handle 32 is fixedly connected to the end of the cleaning scraper 3; before sampling the soil, the sliding handle 32 can be slid first, and then the sliding handle 32 will drive the cleaning scraper 3 to slide inside the sliding groove 33. At this time, the debris and impurities remaining in the area slid by the cleaning scraper 3 will be removed by the cleaning scraper 3; by adding the cleaning scraper 3, the soil can be cleaned before sampling, reducing the garbage and impurities attached to the soil surface, which facilitates the subsequent sampling of the soil by the drill bit 18.
[0028] like Figures 2 to 3 As shown, a water tank 41 is fixedly connected to the top of the processing table 1; a water nozzle 4 is fixedly connected to the side wall of the water tank 41; the water nozzle 4 passes through the processing table 1; after the drill bit 18 completes soil sampling, water can be injected into the water tank 41, and then the water will flow out through the water nozzle 4 to spray and clean the drill bit 18; by adding the water nozzle 4, the drill bit 18 can be cleaned after the work is completed, which facilitates the continued work. The water nozzle 4 can remove the soil attached to the surface of the drill bit 18, reducing the possibility of inaccurate test results due to soil cross-contamination during subsequent testing.
[0029] like Figures 1 to 3 As shown, the top of the cleaning scraper 3 is provided with a placement groove 51; a dust collection box 5 is inserted into the placement groove 51; the dust collection box 5 and the placement groove 51 are correspondingly arranged; when the cleaning scraper 3 removes soil impurities and garbage, if there is a lot of garbage, the garbage will slide down the cleaning scraper 3 to the top of the cleaning scraper 3. At this time, the dust collection box 5 can be inserted into the placement groove 51, and the garbage that slides down to the top of the cleaning scraper 3 will be collected by the dust collection box 5; by adding the dust collection box 5, the garbage that slides down to the top of the cleaning scraper 3 when the cleaning scraper 3 is processing garbage can be collected, reducing the situation where there is too much garbage, causing the garbage to slide down the cleaning scraper 3 to the rear of the cleaning scraper 3.
[0030] like Figure 5 As shown, an anti-slip pad 6 is fixedly attached to the bottom of the support base 12; the anti-slip pad 6 and the support base 12 are correspondingly arranged; when the support base 12 supports the ground next to the soil sampling, the anti-slip pad 6 will preferentially contact the ground, and the anti-slip pad 6 can increase the contact area with the ground; by adding the anti-slip pad 6, the direct contact between the support base 12 and the soil can be reduced when the support base 12 is supported around the soil, and the anti-slip pad 6 can play an anti-slip role, reducing the shaking and displacement of the entire processing table 1 during operation.
[0031] Working principle: Place the processing table 1 around the soil to be sampled, and then fix the four corner support bases 12 at the sampling positions. At this time, the overall height of the processing table 1 can be adjusted by activating the electric actuator 11. Then, the motor 15 can be started. After starting the motor 15, the support sleeve 16 will start to rotate, and the drill bit 18 will also rotate. After aligning the drill bit 18 with the soil to be sampled, activate the cylinder 13. The cylinder 13 will then drive the drill bit 18 to begin downward movement. At this time, the drill bit 18 will rotate and move simultaneously. The drill bit 18 begins its downward movement, continuing to penetrate deeper after contacting the soil. When it encounters branches or gravel, the drill bit 18 will drill through them. Once inside the soil, the sampling port 19 will collect a sample, which is then transferred to the sampling tube 17. The sampling tube 17 can then be removed from the support sleeve 16 and placed on the detection device body 101 for testing. When it is necessary to extract and test the entire soil sample, the spring telescopic rod 22 can be slid. This will cause the blade 2 to move up and down. After the blade 2 is moved to the bottom of the drill bit 18, the motor 15 is started. The motor 15 will drive the blade 2 to rotate. When the blade 2 contacts the soil, it will cut and remove the soil as a whole. Before sampling the soil, the sliding handle 32 can be slid. The sliding handle 32 will then drive the cleaning scraper 3 to slide inside the groove 33. At this time, the residual debris and impurities in the area slid by the cleaning scraper 3 will be removed by the cleaning scraper 3. After the drill bit 18 has completed sampling the soil, it can then... Previously, water was filled into the water tank 41, and then the water flowed out through the water nozzle 4 to spray and clean the drill bit 18. When the cleaning scraper 3 removed soil impurities and debris, if there was a lot of debris, it would slide down the cleaning scraper 3 to the top of the cleaning scraper 3. At this time, the chip collection box 5 could be inserted into the placement groove 51, and the debris that slid down to the top of the cleaning scraper 3 would be collected by the chip collection box 5. When the support base 12 supported the ground next to the soil sampling, the anti-slip mat 6 would make priority contact with the ground, which could increase the contact area with the ground.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
