Description

Technical Field

[0001] The utility model relates to the technical field of environmental improvement, and particularly relates to a sampling mechanism for soil and water environmental improvement. Background Technique

[0002] Soil sample collection refers to the process of taking a representative part of the soil from the wild, fields, cultivation or cultivation units. The collected soil samples are properly processed to prepare analytical samples, and finally analyzed and measured to analyze the soil components, so that people can better understand. Soil environmental monitoring provides reliable basic data for soil environmental management and scientific basis for the effect evaluation of treatment measures, so that the monitoring data can accurately reflect the current situation of soil environmental quality and predict the development trend of soil environmental pollution.

[0003] At present, the structure of the existing soil sampling device is relatively simple, and its shape is similar to that of a Luoyang shovel. When in use, hold the shovel handle and align the sampling shovel with the ground to take samples. However, the soil is sticky. When the shoveled soil needs to be collected, the soil will adhere to the shovel body, making it inconvenient to scrape off the soil. At the same time, the soil adhering to the shovel body will contaminate the next sampling sample. For this reason, we have proposed a sampling mechanism for soil and water environmental improvement. Content of the Utility Model

[0004] Aiming at the deficiencies that the existing sampling process is time-consuming and laborious, and at the same time, it is necessary to take out the sampled soil from the sampler and place it into the storage device for storage, which is not only cumbersome to operate but also extremely easy to cause soil damage during the process of taking out the soil, the utility model provides a sampling mechanism for soil and water environmental improvement, which has the advantages of being able to quickly perform sampling operations and effectively ensuring the integrity of the sampled soil, and solves the problems raised in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0006] A sampling mechanism for soil and water environmental improvement, including a support frame and a plurality of sampling tubes. The bottom of the support frame is connected with a fixed sleeve, and spiral card slots are symmetrically arranged along the circumference at the bottom of the fixed sleeve. The spiral card slots are upwardly extending arc-shaped grooves, and the ends of the spiral card slots extend horizontally;

[0007] The sampling tubes are coaxially connected in the fixed sleeve, and limiting blocks are symmetrically connected to the outer wall of the upper end of the sampling tubes, and the limiting blocks are correspondingly connected in the spiral card slots;

[0008] It also includes a placement box. One side of the placement box is hinged with a top cover. A support pad is fixedly connected inside the placement box, and a placement cavity for placing the support frame and the sampling tubes is provided on the support pad.

[0009] Optionally, the support frame includes a connecting sleeve. The fixed sleeve is fixedly connected to the bottom of the connecting sleeve. A vertical rod is coaxially arranged at the top of the connecting sleeve. The connecting sleeve and the vertical rod are locked by an adjusting bolt. A number of threaded holes cooperating with the adjusting bolt are provided on the outer wall of the vertical rod from top to bottom. Handles are symmetrically connected to the top of the vertical rod.

[0010] Optionally, a number of support rods are fixedly connected to the bottom of the connecting sleeve along the circumferential direction. The fixed sleeve is connected to the connecting sleeve through the support rods. A pedal is perpendicularly connected to the outer wall of one end of the connecting sleeve close to the fixed sleeve.

[0011] Optionally, an anti-slip block is fixedly connected to the top of the pedal, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0012] Optionally, a convex block is fixedly connected to the inner wall of the lower end of the sampling tube along the circumferential direction. The cross-section of the convex block is in an inverted triangular shape.

[0013] Optionally, both ends of the sampling tube are sealed by a sealing cover. The sealing cover covers the two ends of the sampling tube and does not touch the limiting block.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a sampling mechanism for soil and water environment improvement, including a support frame and a plurality of sampling tubes 11. The bottom of the support frame is connected with a fixed sleeve 7. As Figure 1 , 2 shown, the support frame includes a connecting sleeve 5. The fixed sleeve 7 is fixedly connected to the bottom of the connecting sleeve 5. A vertical rod 2 is coaxially arranged at the top of the connecting sleeve 5. The connecting sleeve 5 and the vertical rod 2 are locked by an adjusting bolt 4. And a plurality of threaded holes 3 cooperating with the adjusting bolt 4 are formed in the outer wall of the vertical rod 2 from top to bottom; during actual sampling operations, the operator adjusts the telescopic length of the connecting sleeve 5 and the vertical rod 2 according to the actual use height. After adjusting to a suitable length, the two are locked by the adjusting bolt 4. It not only has a simple structure and is convenient to use, but also effectively improves the practicability of the device.

[0023] To facilitate the user to press the fixed sleeve 7 into the sampled soil, handles 1 are symmetrically connected to the top of the vertical rod 2, which is convenient for the operator to press the fixed sleeve 7. At the same time, an anti-slip sleeve 14 is fixedly connected to the outer wall of the handle 1, which increases the friction on the surface of the handle 1 and ensures a stable grip between the operator's hand and the handle 1. A plurality of support rods 12 are fixedly connected to the bottom of the connecting sleeve 5 along the circumferential direction, and the fixed sleeve 7 is connected to the connecting sleeve 5 through the support rods 12. To improve the stability of the installation of the fixed sleeve 7, the fixed sleeve 7, the connecting sleeve 5 and the support rods 12 are connected by welding, which can further improve the overall strength of the device and is beneficial to extending the service life of the device. The fixed sleeve 7 and the connecting sleeve 5 are coaxially arranged, and the diameter of the fixed sleeve 7 is larger than that of the connecting sleeve 5. To further facilitate the user to press the fixed sleeve 7 and the sampling tube 11 to sample the soil, a pedal 6 is vertically connected to the outer wall of the connecting sleeve 5 near one end of the fixed sleeve 7. During sampling, the operator's foot can simultaneously press the pedal 6 downward, which can ensure that the sampling tube 11 quickly enters the soil, improving the rapid use of the device. And an anti-slip block 13 is fixedly connected to the top of the pedal 6, effectively increasing the friction on the top of the pedal 6.

[0024] In summary, when using the sampling mechanism for soil and water environment remediation, the sampling tube 11 is placed at the bottom of the fixed sleeve 7. Since spiral card slots 8 are symmetrically arranged along the circumferential direction at the bottom of the fixed sleeve 7;

[0025] As Figure 1 shown, the spiral card slots 8 are in a spiral rising structure from the bottom of the fixed sleeve 7 to the other end, and the top of the spiral card slots 8 is horizontal, that is, the end of the spiral card slots 8 is perpendicular to the axis of the fixed sleeve 7. When the sampling tube 11 is coaxially connected in the fixed sleeve 7, limiting blocks 9 are symmetrically connected to the outer wall of the upper end of the sampling tube 11. There is a certain distance between the limiting blocks 9 and the end of the sampling tube 11. At this time, the limiting blocks 9 correspondingly stay in the ends of the spiral card slots 8 and rotate the sampling tube 11, which can drive the limiting blocks 9 to move to the horizontal end of the spiral card slots 8, thus realizing the stable installation of the sampling tube 11. At the same time, with the limiting cooperation between the limiting blocks 9 and the spiral card slots 8, it is convenient for the operator to take out the sampling tube 11 from the soil. To prevent the sampled soil from falling out of the sampling tube 11 and to allow the sampling tube 11 to be quickly installed and disassembled.

[0026] The sampling tube 11 can be a plastic tube or a metal tube. The metal tube is preferably an aluminum alloy tube. During the actual sampling process, after the sampling tube is inserted into the ground surface, if the soil is relatively soft, the soil inside it will fall off when the sampling tube is lifted upward. To prevent the soil from falling off during the upward lifting process, as Figure 1As shown in the figure, a convex block 10 is fixedly connected circumferentially along the inner wall of the lower end of the sampling tube 11. The cross-section of the convex block 10 is in an inverted triangular shape. When the sampling tube 11 is inserted into the soil, the inclined surface of the convex block 10 is in the same direction as the direction of entering the soil, which can enable the sampling tube 11 to be quickly inserted into the ground, ensuring that the soil stably enters the sampling tube 11. When the sampling tube 11 is lifted, the convex block 10 will form a structure similar to barbs, which can prevent the soil from falling out of the sampling tube 11. After the sampling is completed, sealing caps 15 are installed at both ends of the sampling tube 11. Through the sealing of the sealing caps 15, the sealing caps 15 cover both ends of the sampling tube 11 without touching the limiting block 9. The sealing caps 15 can be threadedly connected, buckled, or directly clamped with the sampling tube 11, and the sampled soil can be directly collected. If the soil in the sampling tube 11 needs to be taken out, open the sealing cap 15 and push it out from the end far from the convex block 10 with an instrument.

[0027] At the same time, as Figure 5 shown, the present utility model further includes a placement box 16. A top cover 19 is hinged on one side of the placement box 16. A support pad 18 is fixedly connected inside the placement box 16, such as a sponge pad or a foam pad, etc. In order to protect the support frame and the sampling tube 11, the support pad 18 is preferably a sponge block, and a placement cavity 17 for placing the support frame and the sampling tube 11 is provided on the support pad 18. The sampled sampling tube 11 can be correspondingly placed in the placement cavity 17 for collection. Compared with the traditional sampling device, it can avoid taking out the soil sample for separate collection, thereby ensuring the integrity of the sample.
