Description

Technical Field

[0001] This utility model relates to the technical field of soil testing devices, specifically a novel soil sample filtration device. Background Technology

[0002] Soil monitoring is basically the same as water and air quality monitoring. Various physicochemical properties of soil are measured by using appropriate methods, such as iron, manganese, total potassium, organic matter, total nitrogen, available phosphorus, available boron, fluoride, chloride, mineral oil, and total salt content. Among them, available boron in soil refers to boron elements that can be absorbed and utilized by plants. It has a great influence on plant growth and development and fruit formation. Therefore, measuring the available boron content in soil can guide agricultural production and improve crop yield and quality.

[0003] In the process of detecting available boron in soil, a filtration device is required to filter the sample. Because the inlet of the filtration device is small, one person needs to hold the funnel while another pours the sample for filtration. However, filtration requires two or more people, resulting in high labor costs. Furthermore, the funnel is prone to instability when held, causing it to tip over, which reduces the efficiency of soil filtration and detection. Therefore, we propose a novel soil sample filtration device. Utility Model Content

[0011] Preferably, two fixing screws are provided and installed at the two corners of the placement plate. The end of the placement plate near the two fixing screws is provided with a threaded hole. One end of each fixing screw is inserted into the adjacent threaded hole and threadedly connected to the inner wall of the threaded hole.

[0012] Preferably, one end of each of the two threaded holes is connected to a limiting groove, and one end of each limiting groove near the adjacent fixing block is connected to a shrinkage groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention facilitates the filtration of samples into reagent bottles by placing the filter funnel inside the funnel socket, eliminating the need for two or more people and reducing labor costs. The anti-slip washer at the top of the funnel socket prevents the filter funnel from sliding within the socket, thus improving its stability. A threaded connection between the fixing screw and the inner wall of the threaded hole allows the moving of the limiting sleeve by rotating the fixing screw. A limiting spring between the fixing block and the limiting sleeve facilitates the insertion of the fixing block into the corresponding fixing groove, strengthening the fixation of the support column and improving the stability of the support plate. This solves the problem of instability and tipping of the funnel when manually held, and improves the efficiency of soil filtration and testing. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a novel soil sample filtration device, comprising: a support plate 1, a placement tray 7 connected to the bottom of the support plate 1, insertion slots 9 at the four corners of the top of the placement tray 7, four support columns 2 installed on the bottom of the support plate 1 near the insertion slots 9, and a reagent bottle 6 placed on the top of the placement tray 7; the tops of the four support columns 2 are fixedly installed on the bottom edge of the support plate 1, and the bottoms of the four support columns 2 are slidably inserted into adjacent insertion slots 9, facilitating the positioning of the support columns 2 and mounting the support plate 1 on top of the placement tray 7. Placement slots 8 are evenly distributed on the top of the placement tray 7 near the reagent bottle 6, facilitating both the positioning of the reagent bottle 6 and ensuring one-to-one correspondence with the position of the funnel insertion hole 3.

[0025] The surface of the support plate 1 is provided with funnel insertion holes 3. Anti-slip washers 5 are installed at the top edge of the funnel insertion holes 3. A filter funnel 4 is set inside the funnel insertion hole 3. A filter plate 10 is installed inside the filter funnel 4. The bottom end of the filter funnel 4 passes through the funnel insertion hole 3 and is inserted into the reagent bottle 6. Several funnel insertion holes 3 are evenly arranged and opened at the top of the support plate 1. Each funnel insertion hole 3 corresponds one-to-one with the adjacent placement slots 8 above and below. Anti-slip washers 5 are fixedly installed at the top opening of each funnel insertion hole 3. The size of the support plate can be customized according to the laboratory's testing needs. One size can set the number of funnel insertion holes 3 to 40, so that 40 samples can be filtered at the same time.

[0026] A fixing screw 12 is threadedly installed at one end of the placement plate 7 near the insertion slot 9. One end of the fixing screw 12 is rotatably connected to a limit sleeve 17. A limit spring 16 is installed at one end of the limit sleeve 17. A fixing block 13 is connected to one end of the limit spring 16. A fixing groove 14 is formed on the surface of the support column 2 near the fixing block 13. Two fixing screws 12 are provided and installed at the two corners of the placement plate 7. A threaded hole 11 is formed at one end of the placement plate 7 near the two fixing screws 12. One end of each fixing screw 12 is inserted into the adjacent threaded hole 11 and threadedly connected to the inner wall of the threaded hole 11. Rotating the fixing screw 12 can adjust the length of the fixing screw 12 inserted into the limit groove 18. One end of each of the two threaded holes 11 is connected to a limiting groove 18. The ends of each limiting groove 18 near the adjacent fixing block 13 are connected to a contraction groove 15. The inner walls of both limiting grooves 18 are slidably connected to the side walls of adjacent limiting sleeves 17. The longitudinal sections of both limiting sleeves 17 are rectangular, facilitating the limiting of the limiting sleeves 17 and preventing them from rotating within the limiting grooves 18. Rotating plates 19 are fixedly installed on the ends of both fixing screws 12 near the limiting sleeves 17. Both rotating plates 19 are inserted into the interior of adjacent limiting sleeves 17 and rotatably connected to the inner walls of the limiting sleeves 17. The ends of both limiting sleeves 17 away from the fixing screws 12 are fixedly connected to one end of an adjacent limiting spring 16, facilitating the movement of the limiting sleeves 17 by rotating the fixing screws 12. One end of each of the two shrink grooves 15 is connected to the adjacent insertion groove 9. Both of the two fixing blocks 13 are slidably installed in the adjacent shrink grooves 15. One end of each of the two fixing blocks 13 is fixedly connected to one end of the adjacent limiting spring 16. The other end of each of the two fixing blocks 13 extends out of the adjacent shrink groove 15 and is inserted into the corresponding fixing groove 14.

[0027] When this device is in operation, the filter funnel 4 is placed inside the funnel insertion hole 3, facilitating the filtration of samples into the reagent bottle 6. This eliminates the need for two or more people, reducing labor costs. The anti-slip washer 5 at the top of the funnel insertion hole 3 prevents the filter funnel 4 from sliding within the hole, thus improving its stability. The fixed screw 12 is threaded into the inner wall of the threaded hole 11; rotating the fixed screw 12 moves the limiting sleeve 17. The limiting spring 16 between the fixed block 13 and the limiting sleeve 17 provides elastic support. The fixed block 13 moves within the shrinkage groove 15. When the limiting sleeve 17 moves away from the shrinkage groove 15, the fixed block 13 moves away from the fixing groove 14, which facilitates the removal of the support column 2 from the insertion groove 9, thus separating the support plate 1 and the placement plate 7. When the limiting sleeve 17 moves closer to the shrinkage groove 15, the fixed block 13 is inserted into the corresponding fixing groove 14, which strengthens the fixing effect of the support column 2 and improves the stability of the support plate 1. This solves the problem of instability and tipping of the funnel when it is held by hand, and helps to improve the efficiency of soil filtration and testing.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
