When soil is sampled, firstly, a worker attaches two half-open pipes 11 to form a whole sampling pipe 1, then a drill bit 12 rotates the two half-open thread barrels 14 at the bottom of the sampling pipe 1 through threads, then a connecting pipe 3 rotates to the half-open thread barrels 14 at the top of the sampling pipe 1 through threads, a long rod 34 drives a connecting rod 31 to rotate in the rotating process of the connecting pipe 3 so as to drive a first threaded column 32 to rotate, after the connecting pipe 3 is completely meshed with the two half-open thread barrels 14 at the top of the sampling pipe 1, the first threaded column 32 at the bottom of the connecting rod 31 is completely rotated into a first threaded groove 21 at the top of a driving rod 2, then the worker firstly controls a long rod 34 to shrink, then the two long rods 34 are clamped into circular grooves 37 of a circular plate 36, then the connecting pipe 3 is fixed on a driving device through a coupler, and then sampling work can be carried out;
Specifically, when sampling is performed, the driving device drives the connecting pipe 3 to rotate clockwise from the overlook direction through the coupling, and the long rod 34 fixedly connected to the connecting rod 31 passes through the chute 33, so that the rotating connecting pipe 3 drives the long rod 34 to rotate in the circular groove 37, meanwhile drives the connecting rod 31 to rotate along with the connecting pipe 3, meanwhile, the connecting pipe 3 and the connecting rod 31 drive the sampling pipe 1 and the driving rod 2 to rotate, meanwhile, the sampling pipe 1 drives the drill bit 12 to rotate, and then the driving device is controlled to gradually move downwards, so that the sampling pipe 1 and the drill bit 12 are pushed to gradually extend into the soil layer, and when the drill bit 12 rotates and moves downwards, the sampling pipe 1 is driven to gradually extend into the soil layer, and because the sampling assembly is positioned in the deficient groove 13 in the initial state, in the process of gradually moving downwards in the soil layer, the soil can be prevented from entering the sampling pipe 1 through the deficient groove 13, and after the sampling pipe 1 completely extends into the soil layer, the driving device is controlled to stop moving downwards, and then the sampling pipe 1 is controlled to continue rotating, and sampling can be performed;
More specifically, the electric telescopic rod 35 is controlled to be elongated firstly, when the electric telescopic rod 35 is elongated, the annular plate 36 is driven to move downwards, the annular plate 36 drives the driving rod 2 to gradually move downwards in the sampling tube 1, and in the process of moving downwards the driving rod 2, the first driving block 22 and the second driving block 23 are driven to move downwards, the upper half part of the guide groove 24 on the first driving block is a chute, the lower half part of the guide groove 24 on the second driving block 23 is a straight groove, the upper half part of the guide groove 24 on the second driving block 23 is a chute, and the sliding ball 26 is positioned in the middle part of the guide groove 24 in the initial state;
Therefore, in the process of moving down the first driving block 22, the sliding ball 26 gradually slides into the chute of the guide groove 24 on the first driving block 22, in the process of moving down the second driving block 23, the sliding ball 26 continuously slides in the straight groove of the guide groove 24 on the second driving block 23, so in the process of moving down all the first driving blocks 22, the driven rods 261 on the first driving block 22 are pushed to move towards the inside of the notch 13 by the guide groove 24 on the first driving block 22, so that the scraper 4 is pushed to gradually rotate by taking the rotating shaft as the center of a circle, at the moment, all the scrapers 4 connected with the driven rods 261 gradually rotate out of the notch 13, after the scrapers 4 rotate out of the notch 13, as the sampling tube 1 and the driving rods 2 rotate at the moment, the scrapers 4 are driven to rotate, as the distributed heights of the scrapers 4 are different, soil layers with different depths can be scraped into the sampling tube 1 by the notch 13 in the process of rotating the scrapers 4, and the scrapers 4 fall down on the partition 25 below the first driving block 22 are controlled to restore to the original telescopic state after the electric rods 35 are pulled to the original telescopic state after the scrapers 4 rotate out of the notch 13;
Further, the driving device is controlled to move down continuously, so that the sampling tube 1 and the drill bit 12 are driven to move down continuously, when the depth of the downward movement of the sampling tube 1 is the same as the height of the sampling tube 1 again, the driving device is controlled not to move down, then the electric telescopic rod 35 is controlled to shrink, so that the annular plate 36 is driven to move up, the long rod 34 drives the driving rod 2 to move up in the sampling tube 1, the first driving block 22 and the second driving block 23 are driven to move up in the process of the upward movement of the driving rod 2, the sliding ball 26 is driven to slide in a straight groove on the first driving block 22 continuously in the process of the upward movement of the first driving block 22, and the sliding ball 26 is gradually slid into a chute of a guide groove 24 on the second driving block 23, so that the driven rod 261 connected with the second driving block 23 is driven to move, the scraper 4 connected with the second driving block 23 is rotated out of the cut-out groove 13, and then the sampling tube 1 is driven to rotate out of the scraper 4 and fall into a partition plate 25 in the deep position of the sampling tube 1;
Furthermore, after the sampling is completed, the whole sampling tube 1 is pulled out of the soil layer, then the connecting tube 3 and the drill bit 12 are detached from the sampling tube 1, and then the two half-open tubes 11 are separated, so that the sample soil can be collected;
In summary, by arranging the first driving block 22 and the second driving block 23, in the process of moving down the first driving block 22, the scraper 4 connected with the first driving block 22 can be rotated out of the notch 13 and samples soil, in the process of moving up the second driving block 23, the scraper 4 connected with the second driving block 23 can be rotated out of the notch 13 and samples soil, because the scrapers 4 are distributed at different heights, when the scraper 4 connected with the first driving block 22 is rotated out of the notch 13, the soil with different depths can be sampled, when the scraper 4 connected with the second driving block 23 is rotated out of the notch 13, the soil with deeper depth can be sampled, in the process, the sampling tube 1 does not need to be repeatedly taken out of the soil layer, and then the sampling tube 1 is continuously sampled in the soil layer, so that the soil above the soil layer can be prevented from entering the sampling tube 1 in the process of reinserting the soil layer, the soil layer with different depths can be mixed, the soil with different depths can be prevented from affecting the mixing of the soil, and the soil with different depths can be sampled 1 simultaneously.
Embodiment two:
unlike the first embodiment, the top and the bottom of the scraper 4 are fixedly connected with a baffle 41, and the baffle 41 is positioned in the notch 13 in the initial state; a vertical plate 42 is fixedly connected to the opposite sides of the baffle 41 positioned on the upper side and the lower side of the scraper 4, and one side, close to the rotating shaft, of the vertical plate 42 extends to the middle position of the baffle 41; the driven rod 261 rotates on the vertical plate 42; the tail part of the scraper 4 is fixedly connected with a rubber layer 43 on the surface of the notch 13, and the rubber layer 43 is attached to the scraper 4; the maximum diameter of the scraper 4 is smaller than that of the sampling tube 1, so that the scraper 4 is positioned in the notch 13;
Because the upper side and the lower side of the scraper 4 are fixedly connected with the baffle plates 41, and the opposite sides of the two baffle plates 41 are fixedly connected with the vertical plates 42, when the scraper 4 rotates along with the sampling tube 1, the soil scraped by the scraper 4 can enter a space surrounded by the scraper 4, the two baffle plates 41 and the vertical plates 42, and then the soil can enter the sampling tube 1, in the process, the soil can be prevented from falling along the scraper 4 when the scraper 4 scrapes the soil, and the soil cannot enter the sampling tube 1;
Because the rubber layer 43 has been linked firmly to scraper 4 afterbody position, and rubber layer 43 can seal scraper 4 afterbody, prevents that soil from getting into sampling tube 1 through the clearance between scraper 4 and the lack groove 13, because the maximum diameter of scraper 4 is less than the maximum diameter of sampling tube 1, consequently sampling tube 1 moves down the in-process of soil layer, can prevent scraper 4 and soil layer contact.
