Description

Technical Field

[0001] The utility model relates to the field of soil sampling devices, in particular to a sampler for soil pollution control. Background Art

[0002] Strengthen soil environmental protection, promote the remediation of polluted sites and soil in key areas, and increase investment in soil pollution remediation and management. There are many types of pollutants in the soil, and only by taking control measures for different pollution can significant results be achieved; when analyzing soil pollution, a sampler is needed to sample the soil;

[0003] For example, the Chinese utility model (publication number CN219714796U) discloses a soil sampler for soil pollution control, including a sampling tube, a sampling sleeve, a limit frame, a drill bit and other structures. The limit frame of this technical solution can limit the moving direction of the rotating rod to avoid tilting in the direction when drilling and slipping during use, which affects the drilling efficiency.

[0004] However, the above technical solution still has the following technical problems in actual use: the support legs cannot be adjusted relative to the limit frame. When the soil at the sampling location is in an inclined state, the support rod cannot ensure that the limit frame is in a horizontal state, and thus cannot ensure that the sampling sleeve can move vertically downward. It is inconvenient to use and has poor practicality and applicability. Utility Model Content

[0005] The utility model aims to provide a soil pollution control sampler to solve the problems raised in the above background technology.

[0006] In order to achieve the above object, the utility model provides the following technical solutions:

[0008] Preferably, the clamping device comprises a bidirectional threaded rod, the bidirectional threaded rod is rotatably connected to the fixing frame, both ends of the bidirectional threaded rod are respectively threadedly connected with clamping plates, the two clamping plates are symmetrically arranged about the threaded rod, and the clamping plates are in conflict with the fixing frame.

[0013] The beneficial effects of this technical solution compared with the prior art:

[0014] (1) In this technical solution, the position of the support rod can be adjusted through the threaded rod, and then the distance between the bottom of the support rod and the fixing frame can be adjusted. Thus, no matter what the ground state of the ground to be sampled is, the support rod can be stably inserted into the corresponding position to stably support the fixing frame, and at the same time ensure that the fixing frame is in a horizontal state, thereby ensuring the vertical movement of the sampling tube, enabling the device to be applicable to different soil environments, greatly improving the practicability and applicability. Turning the threaded rod can complete the adjustment, which is convenient to use.

Detailed implementation manners

[0023] The present utility model will be further described in detail below with reference to the drawings and implementation manners:

[0024] As Figures 1 to 6 shown, a sampler for soil pollution treatment includes an operating head 1 and a fixing bracket 5. The operating head 1 is connected with a connecting cylinder 2. The connecting cylinder 2 is threadedly connected with a sampling tube 3. The bottom of the sampling tube 3 is threadedly connected with a drill bit 9. The sampling tube 3 is slidably connected with the fixing bracket 5. The sampling tube 3 and the fixing bracket 5 form a 90-degree angle. The fixing bracket 5 is rotatably connected with a threaded rod 15. The threaded rod 15 is threadedly connected with a support rod 7. The bottom of the support rod 7 is connected with a spike 8. The fixing bracket 5 is connected with a positioning rod 6. The support rod 7 is connected with a positioning block 11. The positioning block 11 is slidably connected with the positioning rod 6. The positioning block 11 can only move up and down along the positioning rod 6. The fixing bracket 5 is connected with a clamping device for restricting the movement of the support rod 7. Three groups of support rods 7 can be provided and are evenly arranged in a ring along the midpoint of the fixing bracket 5. The fixing bracket 5 is connected with a spirit level 4.

[0025] The clamping device includes a bidirectional threaded rod 14. The bidirectional threaded rod 14 is rotatably connected with the fixing bracket 5. Both ends of the bidirectional threaded rod 14 are respectively threadedly connected with a clamping plate 13. The bidirectional threaded rod 14 includes a forward threaded section and a reverse threaded section, that is, the two clamping plates 13 are respectively threadedly connected with the forward threaded rod and the reverse threaded rod. As Figure 3 shown, the two clamping plates 13 are symmetrically arranged left and right with respect to the threaded rod 15. The clamping plate 13 abuts against the fixing bracket 5. The fixing bracket 5 plays a role in restricting the rotation of the clamping plate 13. The threaded rod 15 is fixedly connected with an anti-slip sleeve 12.

[0026] The sampling tube 3 includes a first semi-circular tube 31 and a second semi-circular tube 32, that is, the sampling tube 3 is formed by snap-fitting and splicing the first semi-circular tube 31 and the second semi-circular tube 32. The first semi-circular tube 31 is connected with a clamping strip 16, and the second semi-circular tube 32 is provided with a clamping groove 17. The clamping strip 16 is slidably connected with the clamping groove 17. By means of the clamping strip 16 and the clamping groove 17, relative rotation between the first semi-circular tube 31 and the second semi-circular tube 32 is avoided, and the stability of the snap-fitting of the first semi-circular tube 31 and the second semi-circular tube 32 is improved. The first semi-circular tube 31 and the second semi-circular tube 32 are respectively connected with a positioning ring 10. After the drill bit 9 is threadedly connected with the sampling tube 3, it abuts against the positioning ring 10.

[0027] Splice the sampling tube 3 by inserting the clamping strip 16 into the clamping groove 17 to complete the preliminary splicing of the first semi-circular tube 31 and the second semi-circular tube 32, align the tops of the first semi-circular tube 31 and the second semi-circular tube 32, and at the same time align their bottoms. Then screw on the drill bit 9. At this time, the first semi-circular tube 31 and the second semi-circular tube 32 cannot be easily separated. Then pass the tops of the first semi-circular tube 31 and the second semi-circular tube 32 through the fixing frame 5 and threadedly connect them with the connecting cylinder 2, further preventing the first semi-circular tube 31 and the second semi-circular tube 32 from being easily separated; complete the installation of the sampling tube 3.

[0028] The specific implementation process is as follows:

[0029] During use, assemble the sampling tube 3 according to the above method, and then place the fixing frame 5 at the sampling position. Rotate the corresponding threaded rod 15 according to the sampling position to adjust the distance between the support rod 7 and the fixing frame 5; the following takes Figure 1Taking the adjustment of the left support rod 7 as an example: When it is necessary to adjust the position of the support rod 7, first turn the bidirectional threaded rod 14. The fixing frame 5 plays a role in restricting the rotation of the clamping plate 13. Therefore, as the bidirectional threaded rod 14 rotates, the two clamping blocks move inward or outward along the bidirectional threaded rod 14 at the same time. At this time, the clamping plate 13 can move along the bidirectional threaded rod 14 towards both ends of the bidirectional threaded rod 14, so that the clamping plate 13 no longer clamps the threaded rod 15. Then turn the threaded rod 15. The positioning rod 6 plays a role in restricting the rotation of the positioning block 11. Therefore, as the threaded rod 15 rotates, the support rod 7 moves up or down along the threaded rod 15, and at the same time the positioning block 11 moves up and down along the positioning rod 6, thus completing the adjustment of the position of the support rod 7; after the adjustment is completed, turn the bidirectional threaded rod 14 again so that the two clamping plates 13 clamp the threaded rod 15 (anti-slip sleeve 12). At this time, the threaded rod 15 cannot be easily rotated. After the corresponding support rod 7 is adjusted, part of it can be inserted into the soil to play a role in supporting and fixing the fixing frame 5. Use the level 4 to judge whether the fixing frame 5 is in a horizontal state. After adjusting the fixing frame 5 to a horizontal state, the movement of the sampling tube 3 is a vertical movement. At this time, control the operating head 1 to make the sampling tube 3 rotate and move vertically downward. As the sampling tube 3 moves downward, the soil sample enters the inside of the sampling tube 3. After reaching the appropriate position, the sampling tube 3 can be pulled out. The soil sample adheres to the inside of the sampling tube 3. At this time, the sampling tube 3 can be removed from the connecting cylinder 2, and then slide out of the fixing frame 5. Turn the drill bit 9, and then the first semi-circular tube 31 and the second semi-circular tube 32 can be separated, and then the soil sample can be exposed to the field of view, and the staff can quickly collect the soil sample at the corresponding position.

[0030] In this technical solution, the position of the support rod 7 can be adjusted through the threaded rod 15, and then the distance between the bottom of the support rod 7 and the fixing frame 5 can be adjusted. Thus, no matter what the ground state of the ground to be sampled is, the support rod 7 can be stably inserted into the corresponding position to stably support the fixing frame 5, and at the same time ensure that the fixing frame 5 is in a horizontal state, thereby ensuring the vertical movement of the sampling tube 3, enabling the device to be applicable to different soil environments, greatly improving the practicability and applicability. Turning the threaded rod 15 can complete the adjustment, which is convenient to use; the clamping plate 13 can clamp the threaded rod 15 to prevent the threaded rod 15 from rotating easily, so that the support rod 7 cannot easily change its position relative to the fixing frame 5, thereby improving the support stability of the support rod 7. By turning a bidirectional threaded rod 14, the movement and clamping of the two clamping plates 13 can be completed, with high clamping accuracy and convenient use; the sampling tube 3 is composed of a first semi-circular tube 31 and a second semi-circular tube 32, and it can be opened later to facilitate the quick extraction of soil samples at the corresponding positions; the spirit level 4 can quickly determine whether the fixing frame 5 is in a horizontal state, and then determine whether the sampling tube 3 moves vertically, which is convenient for quick adjustment; the anti-slip sleeve 12 is used to improve the clamping effect of the clamping plate 13 on the threaded rod 15; the positioning ring 10 is used to improve the connection stability between the drill bit 9 and the sampling tube 3.

Specific technical solutions and / or common knowledge such as characteristics that are well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
