Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically to an ecological restoration soil sampling device capable of stratified sampling. Background Technology

[0002] Soil sampling refers to the methods of collecting soil samples, including sampling layout and sampling techniques. Profile soil sampling should be conducted after the profile observation and recording are completed. Before sampling, the profile should be prepared and cleaned, removing the top layer of loose soil, and then samples should be taken layer by layer from top to bottom, starting from the central typical location.

[0003] In existing soil sampling devices, after the sampling device is inserted deep into the soil, it rotates to draw soil into the sampling device for sampling. However, when encountering some hard soil, this method cannot collect soil effectively by simply rotating the device, which requires multiple samplings, reducing efficiency and consuming labor. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an ecological restoration soil sampling device that can perform stratified sampling.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A stratified soil sampling device for ecological restoration, comprising:

[0007] The sampling device body further includes:

[0008] The sampling tube is hollow inside and has a rotating shaft inside.

[0009] A sampling ring is fixedly installed at the bottom of the sampling tube, and an opening is provided on one side of the sampling ring. The cross-sectional shape of the sampling ring is V-shaped.

[0010] The plug is fixedly installed at the bottom of the sampling ring;

[0011] The sampling basin is rotatably mounted on the top of the plug and located inside the sampling tube, and the top of the center of the sampling basin is fixedly connected to the bottom of the rotating shaft.

[0012] A partition, which is fixedly installed inside the sampling basin, divides the interior of the sampling basin into multiple chambers of the same size;

[0013] A scraper is fixedly installed on the surface of the partition plate close to the side wall of the sampling basin, and one side surface of the scraper slides in contact with the inner wall of the sampling ring.

[0014] The external power drives the rotating shaft to rotate, which in turn drives the sampling basin and scraper to rotate. The scraper then scrapes external soil from one side of the sampling ring opening and into the sampling basin.

[0015] Preferably, an inclined feeding plate is fixedly installed on the surface corresponding to the rotation direction of the scraper for conveying soil.

[0016] Preferably, the outermost arc formed between the two partitions is equal to the arc of the opening on one side of the sampling ring.

[0017] Preferably, the scraper is a solid plate, and the surface of the scraper and the inclined feeding plate near the sampling basin is flush with the edge of the sampling basin.

[0018] Preferably, the outer surface of the sampling tube is provided with scale lines to determine the depth of penetration into the soil.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The rotating shaft moves the sampling basin, partition, and scraper. The scraper scrapes soil from the opening of the sampling ring into the sampling basin. The partition separates each soil sample, enabling convenient and efficient multiple sampling of hard soil. This avoids substandard sampling due to hard soil, which would otherwise require multiple samplings and waste labor, thus improving sampling efficiency. Attached Figure Description

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] Example 1

[0029] like Figure 1-4 As shown, an ecological restoration soil sampling device capable of stratified sampling includes:

[0030] Sampling device body 1, the sampling device body 1 also includes:

[0031] The sampling cylinder 2 is hollow inside and has a rotating shaft 5 inside.

[0032] The sampling ring 3 is fixedly installed at the bottom of the sampling tube 2, and has an opening on one side. The cross-sectional shape of the sampling ring 3 is V-shaped.

[0033] Plug 4 is fixedly installed at the bottom of sampling ring 3;

[0034] The sampling basin 6 is rotatably mounted on the top of the plug 4 and located inside the sampling tube 2, and the top of the center of the sampling basin 6 is fixedly connected to the bottom of the rotating shaft 5.

[0035] The partition 7 is fixedly installed inside the sampling basin 6, dividing the interior of the sampling basin 6 into multiple chambers of the same size;

[0036] The scraper 8 is fixedly installed on the surface of the partition 7 close to the side wall of the sampling basin 6, and one side surface of the scraper 8 slides in contact with the inner wall of the sampling ring 3.

[0037] The external power drives the rotating shaft 5 to rotate, which in turn drives the sampling basin 6 and the scraper 8 to rotate. The scraper 8 rotates and scrapes the external soil on one side of the sampling ring 3 opening into the sampling basin 6.

[0038] Specifically, after the entire device is placed in the soil to be sampled, external power rotates the rotating shaft 5. The rotation of the shaft 5, in turn, rotates the sampling basin 6. During the rotation of the sampling basin 6, the spaces created by the partitions 7 and the scraper 8 also rotate. The scraper 8 slides along the inner wall of the sampling ring 3. When one scraper 8 reaches the starting section of the opening side of the sampling ring 3, its end contacts the soil, scraping it off. The scraped soil directly enters the sampling basin. Inside the sampling ring 6, the scraper 8 slides along the opening of the sampling ring 3 and scrapes the soil until the scraper 8 moves to the end of the sampling ring 3 and enters the interior of the sampling ring 3, thus completing one soil sampling. After adjusting the depth, the same principle is used to rotate again to complete multiple samplings. This achieves the effect of conveniently and easily sampling multiple times for hard soil, avoiding the situation where the soil is too hard and the sampling is not up to standard, thus requiring multiple samplings and wasting labor, thereby improving sampling efficiency.

[0039] In this embodiment: an inclined feeding plate 9 is fixedly installed on the surface of the plane corresponding to the rotation direction of the scraper 8, for conveying soil.

[0040] Specifically, when the scraper 8 is scraping the soil, the scraped soil falls directly onto the inclined feeding plate 9 by its own gravity. The soil falling onto the inclined feeding plate 9 is transported directly into the sampling basin 6 by its own gravity, thereby collecting the soil. This achieves the effect of automatically collecting the soil on the scraper 8 and improves the efficiency of soil sampling.

[0041] In this implementation example: the outermost arc formed between the two partitions 7 is equal to the arc of the opening on one side of the sampling ring 3.

[0042] Specifically, when the sampling basin 6 is stationary, the two partitions 7 are located on either side of the opening of the sampling ring 3. When the sampling basin 6 rotates, a scraper 8 located on the rear side of the rotation direction comes into contact with the soil, scraping it off. When the scraper 8 moves from one end of the sampling ring 3 opening to the other end, a single soil sample is completed. Then, it delves deeper into the soil again for a second soil sample, thus achieving the effect of multiple soil samplings. This avoids soil mixing during multiple samplings, which could affect the accuracy of soil sampling and testing.

[0043] In this implementation case: the scraper 8 is a solid plate, and the surface of the scraper 8 and the inclined feeding plate 9 near the sampling basin 6 is flush with the edge of the sampling basin 6.

[0044] Specifically, the solid plate can effectively scrape soil over a large area. The surface of the scraper 8 and the inclined feeding plate 9 near the sampling basin 6 is flush with the edge of the sampling basin 6, which can prevent soil from falling above the edge of the sampling basin 6 when it enters the interior of the sampling basin 6, thus avoiding inconvenience in cleaning. It also avoids soil mixing, ensures the accuracy of soil sampling, enhances the practicality of the device, and facilitates subsequent cleaning.

[0045] In this implementation case: the outer surface of the sampling tube 2 is provided with scale lines 11 to determine the depth of penetration into the soil.

[0046] Specifically, when the user is taking soil samples, as the device gradually enters the soil, the user can observe the scale line 11 to determine the depth of the sampling ring 3 underground. This facilitates the user in sampling soil at different depths, improves the applicability of the device, and ensures the persuasiveness of the soil sampling.

[0047] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
