Technical Field

[0001] This utility model relates to the field of soil sample storage technology, and in particular to a soil sample storage device for tobacco-grain intercropping. Background Technology

[0002] Soil carbon sequestration refers to the process of fixing atmospheric carbon dioxide in the soil through various measures to increase soil carbon storage and mitigate climate change.

[0003] my country's tobacco-producing regions, such as Yunnan, have a wide variety and quantity of tobacco-growing soils. Researching and improving the carbon sequestration capacity of these soils is of great significance to these areas. Currently, some regions employ intercropping models for tobacco cultivation, such as intercropping sweet potatoes or other grain crops in tobacco-growing soils. When studying the impact of tobacco-grain intercropping on soil properties, specific containers are needed to store soil samples, such as smooth-mouthed bottles with sun protection. However, when testing soil samples, problems often arise such as sample clumping or excessive impurities in the bottle, leading to long soil sample pretreatment times or insufficient sample retention after testing.

[0030] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] When taking soil samples from a specific container for testing, it is often found that the samples accumulate and clump together in the bottle, or there are too many impurities, resulting in a long soil sample pretreatment time. Alternatively, after testing, it is found that the amount of soil sample retained is insufficient, which affects the verification of subsequent test results.

[0032] Therefore, this application creatively proposes a soil sample storage device for tobacco-grain intercropping. The device includes a box, a first partition structure, a second partition structure, and a filter structure. When storing soil samples, the box is first opened, and then the soil is poured into the box. After passing through the filter structure, impurities are filtered out. The filtered soil is relatively loose and falls to the bottom of the first storage chamber, avoiding soil sample accumulation and clumping, and shortening the pretreatment time before soil sample testing. At the same time, a portion of the soil falls to the bottom of the adjacent storage chamber through the connecting hole to be reserved as a spare sample. After both the soil sample for testing and the spare sample are loaded, the part of the filter structure in the storage chamber is moved to the recovery space, thereby transferring impurities to the recovery space and preventing some impurities from falling into the storage chamber during the transfer device.

[0033] The present invention will be specifically described below through specific embodiments.

[0034] Reference Figures 1 to 3As shown in the figure, this application provides a soil sample storage device for tobacco-grain intercropping. The device includes a box 1, a first partition structure 2, a second partition structure 3, and a filter structure 4. The first partition structure 2 is located inside the box 1 and divides the internal space of the box 1 into a storage space 11 and a recovery space 12. The second partition structure 3 is located inside the storage space 11 and divides the storage space 11 into at least two storage cavities 111, and has a connecting hole 31 connecting adjacent storage cavities 111. The box 1 has a first channel 13 connecting the storage space 11 to the outside, and the first partition structure 2 has a second channel 21 connecting the recovery space 12 and a storage cavity 111. The filter structure 4 can move between the recovery space 12 and the corresponding storage cavity 111 through the first channel 13 and the second channel 21.

[0035] When storing soil samples, first open the box 1, then pour the soil into the box 1. After passing through the filter structure 4, impurities are filtered out. The filtered soil is relatively loose and falls to the bottom of the first storage chamber 111, preventing the soil samples from accumulating and clumping, and shortening the pretreatment time before soil sample testing. At the same time, some soil falls through the connecting hole to the bottom of the adjacent storage chamber 111 as a spare sample. After both the soil sample for testing and the spare sample are loaded, the part of the filter structure 4 in the storage chamber 111 is moved to the recovery space 12, thereby transferring impurities to the recovery space 12 and preventing some impurities from falling into the storage chamber 111 during the transfer device.

[0036] It is understood that the shape of the box 1 can be a regular shape such as a cylinder, frustum, or polygonal prism, or any other irregular shape, as long as it meets the spatial division requirements. In this embodiment, the shape of the box 1 is a cuboid.

[0037] Correspondingly, the shapes of the storage space 11 and the recycling space 12 largely depend on the shape of the box 1 and are influenced to some extent by the first partition structure 2. In this embodiment, for ease of processing and structural expansion, the first partition structure 2 is set as a rectangular plate, so that both the storage space and the recycling space 12 are cuboid in shape. The second partition structure 3 is set as a rectangular plate, so that both the storage cavity 111 are cuboid in shape.

[0038] For example, refer to Figure 1 and Figure 2 As shown, the box 1 includes a base and multiple baffles. By setting different specifications of sliding grooves on the base, the baffles can be combined with the corresponding sliding grooves to form the box 1. The first partition structure 2 and the second partition structure 3 can be combined with their corresponding sliding grooves to form corresponding storage spaces 11 and recycling spaces 12, as well as a corresponding number of storage cavities 111.

[0039] In an alternative example, an inclination angle is provided at the sliding fit between the housing 1 and the filter structure 4. After the filter structure 4 is completely removed from the storage cavity 111, the filter structure 4 is changed from a horizontal state to an inclination state, so that most of the impurities on the filter structure 4 can be poured into the recycling space 12.

[0040] In another alternative example, a scraper 5 is provided within the recycling space 12, positioned above the filter structure 4, so that as the filter structure 4 moves relative to the scraper 5, the scraper 5 can scrape off impurities from the filter structure 4. By using the scraper 5, impurities on the filter structure 4 can be efficiently removed simply by moving the filter structure 4 horizontally, while also reducing operational complexity.

[0041] Furthermore, the scraper 5 is detachably equipped with a scraping structure 51 on the side facing the filter structure 4. By replacing the scraping structure 51 with different specifications and shapes, it is possible to better adapt to the corresponding soil sample, thereby fully scraping away impurities on the filter structure 4. For example, the scraping structure 51 can be a brush.

[0042] In addition, the scraping structure 51 can also be protrusions of different sizes and shapes that are densely distributed on the scraper 5, so as to achieve full scraping of impurities.

[0043] In some examples, refer to Figure 2 and Figure 3 As shown, the filter structure 4 includes a filter plate 41 and an extension plate 42 connected to each other. The extension plate 42 is adapted to pass through the first channel 13, and the filter plate 41 is gapped through the second channel 21. The projection of the scraper 5 along the moving direction of the filter structure 4 at least partially falls on the cross-section of the second channel 21. Through the gap fit between the second channel 21 and the filter plate 41, impurities on the filter structure 4 are prevented from being scraped off by the side wall of the second channel 21 and falling onto the bottom surface of the storage cavity 111; while the projection of the scraper 5 and the second channel 21 at least partially overlaps, ensuring that the scraper 5 can effectively scrape off impurities on the filter structure 4.

[0044] Here, "fitting" refers to the two structures fitting together in shape and size, which in this embodiment can prevent small impurities or soil from leaking out of the box 1; "gap fit" refers to the existence of a certain gap between the two structures in cross-section, which in this embodiment can ensure that the inner wall of the second channel 21 will not scrape the impurities on the filter structure 4, and prevent soil from falling into the recycling space 12.

[0045] Furthermore, in some examples, a sealing ring is provided at the end of the extension plate 42 away from the filter plate 41, and the sealing ring is pressed against the inner peripheral wall of the first channel 13. The sealing ring ensures the airtightness of the interface between the filter structure 4 and the housing 1. In this embodiment, an operating rod is connected to the end of the extension plate 42 away from the filter plate 41 to facilitate external operation of the filter structure 4.

[0046] In some examples, refer to Figure 1 and Figure 2 As shown, the surface of the box 1 has a material hole 14 communicating with the storage space 11. The material hole 14 is coaxially arranged with the connecting hole 31. The side wall of the box 1 has at least one air hole 15 communicating with the storage cavity 111. The air hole 15 is used to connect to an air supply device. It can be understood that, in order to facilitate the filling of soil, the material hole 14 is located at the top of the box 1. At the same time, the axis of the material hole 14 can be aligned with the vertical axis of the storage cavity 111 so as to evenly distribute the soil on the bottom surface of the storage cavity 111. Gas can also be introduced into the storage cavity 111 through the air hole 15 to blow away the soil, making the soil more evenly distributed on the bottom surface of the storage cavity 111. At the same time, soil can be preferentially placed in the first layer of the storage cavity 111.

[0047] For example, there are at least two vents 15 and they are evenly distributed around the perimeter of the box 1, thereby spreading the soil relatively evenly around the perimeter of the storage cavity 111.

[0048] Furthermore, in some examples, the filter structure 4 is provided with a through hole 43, and the axes of the through hole 43 and the connecting hole 31 are collinear on the orthographic projection plane along the moving direction of the filter structure 4. With the above arrangement, the placement of the prepared soil sample can be accelerated by adjusting the through hole 43, the connecting hole 31 and the material hole 14, and the soil can also be filtered by partially using the filter structure 4.

[0049] In some examples, the device also includes a feed tube 6, which can be inserted into the feed hole and / or connecting hole 31. A locking structure 7 is provided on the side of the housing 1 with the feed hole, and the locking structure 7 engages with the feed tube 6. The feed tube 6 improves the ease of pouring soil and allows for directional pouring of soil by inserting it into the connecting hole 31, thus accelerating the storage of ready-to-use soil samples. The locking structure 7 allows staff to adjust the insertion depth of the feed tube 6 into the housing 1.

[0050] In this embodiment, the locking structure 7 includes a ring 71 and an abutment rod 72 threadedly connected to the ring 71. After the material tube 6 passes through the ring 71, the material tube 6 is fixed or released by screwing the abutment rod 72.

[0051] In some examples, to facilitate user observation of soil placement, at least one side of the container 1 can be made of transparent acrylic sheet. The other parts of the container can be made of materials such as plastic or stainless steel.
