[0002] When testing environmental soil, it is often necessary to collect soil in the test area and then test and analyze the soil. The quality of the environment in the test area can be judged and analyzed based on the stock and survival of microorganisms in the soil. When testing the soil, it is necessary to sample and collect soil, and it is necessary to collect soil at different depths and then compare the data.

[0003] A Chinese patent discloses a sampling device for detecting soil microbial diversity (publication number: CN117946845B). The device is a movable sampling device that can be dragged to a sampling point, and uses a rotatable sampler to automatically collect soil and store the collected soil. The sampling process replaces manual sampling, reduces the labor burden of the sampler, and makes the transportation of the sampling device and the sample more convenient and light.

[0004] However, the above soil collecting device has the problem of being large and inconvenient to carry, and it is not possible to collect soil at different depths when collecting soil, nor is it possible to collect complete soil. Although the existing cylindrical soil collecting devices on the market can take out complete and unbroken soil, they cannot be taken out completely from the cylinder after collecting the soil. When taking out the soil, the soil will be broken and fall off, which will destroy the layers of the soil itself, resulting in the inability to accurately collect the soil at the specified depth.

[0010] Furthermore, the connecting tube includes an upper threaded ring and a lower threaded ring, both of which are threadedly connected to the outer sleeve, and a transparent elastic membrane is fixedly connected between the upper threaded ring and the lower threaded ring, and the transparent elastic membrane is concave inward, that is, the transparent elastic membrane has elastic force inward.

[0011] Furthermore, the upper ends of several of the upper threaded rings are fixedly connected with threaded inner sleeves, and one upper threaded ring is threadedly connected to another lower threaded ring. In this way, several connecting tubes can be threaded together end to end, and the connecting tube closest to the driving column is threadedly connected to the driving column through the threaded inner sleeve.

Then the test tube containing the reagent and soil is inserted into the positioning sleeve. Finally, the coil plate in the vibration sleeve is controlled to be powered on and off continuously, so that the vibration ball can be controlled to jump up and down in the vibration sleeve, and then the vibration ball vibrates, so that the vibration sleeve drives the entire fixed ring to vibrate, and then the soil and reagent in the test tube are mixed, thereby increasing the mixing efficiency and facilitating the subsequent detection using the mixed liquid and test paper.

[0018] 3. When the present invention is used, the driving column is removed when backfilling the soil, and then the drainage rod is used to support the soil in the inner sleeve, and then the entire outer sleeve can be pulled out. In this way, after the entire device is taken out, the soil will be pushed into the soil by the drainage rod for backfilling, thereby reducing damage to the natural environment and increasing the environmental friendliness of the present invention.

Specifically, a plurality of storage grooves are opened on the outer wall of the rotating sleeve 208, and a plurality of magnet plates 210 are inserted in the storage grooves. The direction of the magnetic field can be controlled by switching the current direction of the coil poles 212 back and forth, so as to make the rotating sleeve 208 rotate in the power sleeve 205 by utilizing the principle that like poles repel each other and unlike poles attract each other, thereby driving the soil sampling barrel to be inserted into the soil for sampling;

[0038] See also Figure 8 , 9 , 11, the soil extraction pipe includes an outer sleeve 3 and an inner sleeve 6, the inner sleeve 6 is threadedly connected in the outer sleeve 3, and the outer sleeve 3 is threadedly connected in the rotating sleeve 208.

[0039] The outer sleeve 3 includes a soil-breaking sleeve 300, and a thread is provided on the outer wall of the soil-breaking sleeve 300. The outer sleeve 3 is threadedly connected to the rotating sleeve 208 through the thread on the outer wall of the soil-breaking sleeve 300, and the thread on the outer wall of the soil-breaking sleeve 300 also helps the soil-breaking sleeve 300 to be inserted into the soil.

[0040] The inner sleeve 6 includes a driving column 601, and the driving column 601 is threadedly connected to the inner wall of the outer sleeve 3. A long strip magnet is embedded in the driving column 601. The lower end of the driving column 601 is connected to a plurality of connecting cylinders 7, and the plurality of connecting cylinders 7 are threadedly connected. The inside of the driving column 601 is symmetrically slidably connected with an abutment block 605 for limiting the driving column 601. The abutment block 605 abuts against the inner wall of the outer sleeve 3 to prevent the coil column 212 from directly driving the driving column 601 to rotate. The inside of the driving column 601 is also slidably connected with a push rod 603, and the push rod 603 The lower end of the driving column 601 is fixedly connected with a top plate 602, and the top plate 602 is located in the connecting tube 7. The upper end of the top rod 603 is fixedly connected with a push block 606, and the push block 606 is located between the two abutment blocks 605. The abutment block 605 can be pushed to abut against the outer sleeve 3 by the push block 606. Specifically, a movable cavity 604 for sliding the push block 606 is opened inside the driving column 601, and a connecting elastic rope 607 is fixedly connected between the two abutment blocks 605. More specifically, a transition channel is opened in the middle of the push block 606, and the connecting elastic rope 607 is located in the transition channel;

[0041] See also Fig.11 The connecting tube 7 includes an upper threaded ring 700 and a lower threaded ring 702, both of which are threadedly connected to the outer sleeve 3, and a transparent elastic film 703 is fixedly connected between the upper threaded ring 700 and the lower threaded ring 702, and the transparent elastic film 703 is concave inwardly, that is, the transparent elastic film 703 has elastic force inwardly;

[0042] The upper ends of several upper threaded rings 700 are fixedly connected with threaded inner sleeves 701, and one upper threaded ring 700 is threadedly connected to another lower threaded ring 702. In this way, several connecting tubes 7 can be threaded together end to end, and the connecting tube 7 closest to the driving column 601 is threadedly connected to the driving column 601 through the threaded inner sleeve 701. The interiors of the upper threaded rings 700 and the lower threaded rings 702 are also embedded with embedded magnet blocks 704.

[0043] Example 3, please refer to Figure 4 and Figure 7 , based on Example 2, the interior of the fixing ring 200 is fixedly connected to the equipment compartment 202, and the interior of the equipment compartment 202 is equipped with a driving chip, a controller and a battery. The driving chip, the controller and the battery are all prior arts and will not be described in detail here;

[0044] A plurality of positioning sleeves 203 are slidably mounted inside the fixing ring 200, and a plurality of extrusion springs are fixedly connected inside the positioning sleeves 203. When the test tube 4 is inserted into the positioning sleeves 203, the test tube 4 can be positioned by the plurality of extrusion springs.

[0045] Several vibration structures 8 are also fixedly and slidably installed inside the fixing ring 200. The vibration structures 8 are connected to the positioning sleeves 203 via connecting springs 204, and the vibration structures 8 are evenly distributed between the fixing rings 200.

[0046] Specifically, a plurality of protrusions are fixedly connected to the outer wall of the positioning sleeve 203, and a plurality of rectangular grooves corresponding to the protrusions are opened on the inner wall of the fixing ring 200, and the protrusions are slidably connected in the rectangular grooves;

[0047] The vibration structure 8 includes a vibration sleeve 800, and coil plates 801 are symmetrically fixedly connected inside the vibration sleeve 800. A vibration ball 802 is movably arranged inside the vibration sleeve 800 between the two coil plates 801, and the vibration ball 802 is made of iron material;

[0048] Please participate Fig.10 The support sleeve 5 is threadedly connected to the upper end of the power sleeve 205, and a connecting window 501 is symmetrically opened on the outside of the support sleeve 5, through which the connecting window 501 is convenient for operating the connecting cylinder 7, and the interior of the support sleeve 5 is also fixedly connected to a limiting sleeve 502, and a docking port 503 is opened in the middle of the limiting sleeve 502, and the docking port 503 presents a state in which the upper and lower openings are large and the middle opening is small. In this way, the outer sleeve 3 and the inner sleeve 6 can be easily entered into the docking port 503, and then the limiting sleeve 502 is used to limit the outer sleeve 3 and the inner sleeve 6.

[0049] The working principle of the present invention is: when in use, the power structure 2, the soil taking pipe, the support sleeve 5 and the test tube 4 are taken out from the box body 1, and then the support sleeve 5 is first connected with the power sleeve 205, and then the soil taking pipe passes through the support sleeve 5 and is connected with the rotating sleeve 208 in the power sleeve 205, and then the limit slider 207 is connected with the limit groove on the outer wall of the outer sleeve 3. When the whole device is assembled, the power is turned on to rotate the rotating sleeve 208. When the rotating sleeve 208 rotates, it will drive the outer sleeve 3 to insert into the soil. When the outer sleeve 3 is inserted into the soil, the soil will flow into the inner sleeve 6, so that the soil is collected by the inner sleeve 6;

[0050] When the soil flows into the inner sleeve 6, it will enter the connecting sleeve 7. When the limiting slider 207 slides to the inner top of the limiting groove on the outer wall of the outer sleeve 3, the rotating sleeve 208 stops rotating when the power is turned off. At this time, the soil in the connecting sleeve 7 is in a state of pressing against the top plate 602, and the driving column 601 is in the inner area of ​​the rotating sleeve 208. (The limited length of the limiting groove means that the depth to which the outer sleeve 3 can be inserted into the soil is fixed. The fixed depth to which the outer sleeve 3 is inserted into the soil means that the soil contained in the inner sleeve 6 is limited. When the limit is exceeded, the top plate 602 will be squeezed. That is to say, when the limiting slider 207 moves to the inner top of the limiting groove, the soil in the inner sleeve 6 reaches the limited value). When the top plate 602 is squeezed, the pushing block 606 will move upward. When the pushing block 606 moves upward, it will be separated from the two abutting blocks 605. At this time, the two abutting blocks 605 will be retracted under the action of the connecting elastic rope 607, thereby separating from the abutment with the outer sleeve 3.

[0051] At this time, the magnet plate 210 is pulled out, and then the power is turned on. At this time, the driving column 601 will start to rotate under the action of the coil columns 212 and the long strip magnets. Since the driving column 601 is threadedly connected to the outer sleeve 3, the entire inner sleeve 6 will rotate. At this time, the outer sleeve 3 is limited by hand to prevent it from rotating. At this time, the inner sleeve 6 will move to the outside of the outer sleeve 3, and along with the movement, the connecting tube 7 will move to the inner area of ​​the rotating sleeve 208. An embedded magnet block 704 is provided in the connecting tube 7. At this time, the connecting tube 7 will also rotate (at this time, although the size of the embedded magnet block 704 is smaller than the long strip magnet in the driving column 601, it cannot reach the torque generated when the driving column 601 rotates, but at this time, only the upper threaded ring 700 and the lower threaded ring 702 of the connecting tubes 7 are threadedly connected to the outer sleeve 3, that is, the threaded area is small, so the inner sleeve 6 can also be driven to rotate under the action of the coil column 212 and the embedded magnet block 704), so that the inner sleeve 6 continues to move upward, thereby facilitating the collection of the collected soil;

[0052] When the inner sleeve 6 moves upward, the soil will be locked by the transparent elastic film 703 to prevent the soil from falling (the soil will stretch the transparent elastic film 703 when entering the inner sleeve 6, so the transparent elastic film 703 will give the soil an extrusion force). When the inner sleeve 6 moves to a suitable position, the soil of the corresponding depth can be selected. When collecting the soil, it is only necessary to rotate the corresponding connecting tube 7 to separate it from the other connecting tubes 7. After taking out the soil of the corresponding depth, the other connecting tubes 7 can be connected to facilitate the subsequent backfilling of the soil.

[0053] When the soil is collected, it can be poured into the test tube 4 and then the corresponding reagent is added into the test tube 4. Then the test tube 4 containing the reagent and soil is inserted into the positioning sleeve 203. Finally, the coil plate 801 in the vibration sleeve 800 is controlled to be powered on and off continuously, so as to control the vibration ball 802 to jump up and down in the vibration sleeve 800, thereby making the vibration ball 802 vibrate, so that the vibration sleeve 800 drives the entire fixed ring 200 to vibrate, and then the soil and reagent in the test tube 4 are mixed, thereby increasing the mixing efficiency, which is convenient for subsequent detection using the mixed solution and test paper;

[0054] When backfilling the soil, remove the driving column 601, then use the drainage rod 10 to support the soil in the inner sleeve 6, and then pull out the entire outer sleeve 3. When the outer sleeve 3 is difficult to pull out, the magnet plate 210 can be reinstalled, and then the rotating sleeve 208 can be used to drive the outer sleeve 3 to reverse. In this way, after the entire device is taken out, the soil will be pushed into the soil by the drainage rod 10 for backfilling, thereby reducing damage to the natural environment and increasing the environmental protection of the present invention.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
