Description

Technical Field

[0001] This utility model specifically relates to a sample storage device for testing the quality of arable land soil, belonging to the field of soil sample technology. Background Technology

[0002] In agricultural production, soil quality testing is a crucial step in ensuring crop yield and quality. By analyzing soil samples, we can accurately grasp information such as soil fertility, pH, and heavy metal content, thus providing data support for scientific fertilization and soil improvement. As an important part of the soil testing process, the rationality of the design of the sample storage device directly affects the accuracy and reliability of the test results.

[0003] Currently, most soil quality testing equipment for farmland uses a single container for sample storage. A single container makes it difficult to effectively classify soil samples. In actual testing, soil samples often come from different plots, different depths, and even different sampling times. If these samples are mixed in the same container, it is easy to cause sample confusion, which not only increases the difficulty of subsequent testing but may also lead to incorrect test conclusions due to sample errors, thus misleading agricultural production decisions.

[0004] To address the above issues, this application proposes a sample storage device for testing the quality of arable land soil. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a sample storage device for testing the quality of arable land soil. When samples need to be stored, the inner rotating plate rotates to move the empty sample tubes sequentially to below the outlet, and the electric push rod drives the lifting block to push them out for easy access by the operator. After filling, the sample tubes are placed back into the bottom groove along the outlet, and the inner rotating plate then aligns the next set of empty tubes with the outlet, repeating the cycle. This design simplifies the sample storage and retrieval process, significantly improves work efficiency, and the independent classification and storage of sample tubes effectively avoids the risk of sample confusion, thus solving the problems mentioned in the background art.

[0006] A sample storage device for testing arable land soil quality includes: a classification and storage mechanism, comprising a storage cylinder, a rotatable inner rotating plate inside the storage cylinder, multiple sets of tube grooves evenly spaced on the inner rotating plate, and a set of sample tubes in each set of tube grooves; an outlet tube is opened on one side of the upper part of the storage cylinder; an electric push rod is installed on one side of the lower part of the storage cylinder, and a lifting block is installed on the upper end of the electric push rod; and a compaction mechanism, comprising a fixed cylinder installed above the storage cylinder, and a liftable compaction block is provided inside the fixed cylinder, a pressure rod is installed on the upper end of the compaction block, and a return spring is provided on the outside of the pressure rod.

[0007] In a preferred embodiment, a set of bottom rings is installed below each set of pipe grooves, and the lifting block is located below the bottom rings, with a diameter smaller than the inner diameter of the bottom rings.

[0008] In a preferred embodiment, the inner rotating plate is rotatably connected to the inner wall of the storage cylinder, and a rotating rod is installed in the middle of the upper part of the inner rotating plate, with the upper end of the rotating rod penetrating the storage cylinder and connected to the rotating plate.

[0009] In a preferred embodiment, multiple sets of indicators are installed around the rotating plate, and the positions and numbers of the multiple sets of indicators correspond to the positions and numbers of the multiple sets of sample tubes, respectively.

[0010] In a preferred embodiment, a cap is threaded onto the outlet, and a handle is installed on the storage cylinder.

[0011] In a preferred embodiment, a battery is installed at the bottom inside the storage cylinder, and a controller is installed at the top of the storage cylinder. The battery is electrically connected to the electric actuator through the controller.

[0012] In a preferred embodiment, the fixed cylinder is internally connected to the storage cylinder, a pressure plate is installed on the upper end of the pressure rod, the upper end of the reset spring is connected to the pressure plate, and its lower end is connected to the fixed cylinder.

[0013] In a preferred embodiment, a base plate is installed below the storage cylinder, and multiple sets of support legs are installed below the base plate.

[0014] Beneficial effects:

[0015] 1. By designing a classified storage mechanism, when soil samples need to be stored, the inner rotating plate rotates, causing the empty sample tubes to rotate sequentially to below the outlet at the top. Then, the electric actuator drives the lifting block to rise, pushing the sample tubes out along the outlet. This allows operators to easily remove the sample tubes for soil filling. After sample collection, operators simply place the soil-filled sample tubes back into the bottom groove on the inner rotating plate along the outlet. Then, the inner rotating plate rotates again, aligning the next set of empty sample tubes with the outlet. The above process is repeated to complete the storage of the next sample. This design facilitates the classified storage of samples and makes the sample removal or placement process simple and convenient, improving work efficiency. Furthermore, the independent sample tube design can avoid cross-contamination and confusion between samples.

[0016] 2. By designing a compaction mechanism, when the soil-filled sample tube rotates with the inner rotating plate to directly below the fixed cylinder, the pressure plate applies downward pressure, causing the pressure rod to move down synchronously, so that the compaction block enters the sample tube to compact the soil sample, effectively eliminating internal voids in the sample. The compacted sample is more compact during storage or transportation, and the sample is less likely to spill out. During the pressure application process, the return spring is compressed and stores energy. When the pressure application is completed, the return spring releases its elastic potential energy, causing the compaction block to return to its original position. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5As shown, a sample storage device for testing the quality of arable land soil includes: a classification and storage mechanism 1, including a storage cylinder 11, a rotatable inner rotating plate 111 inside the storage cylinder 11, multiple sets of tube grooves evenly spaced on the inner rotating plate 111, and a set of sample tubes 112 in each set of tube grooves, an outlet 12 on one side of the upper part of the storage cylinder 11, an electric push rod 113 installed on one side of the lower part of the storage cylinder 11, and a lifting block 115 installed on the upper end of the electric push rod 113; and a compaction mechanism 2, including a fixed cylinder 21 installed above the storage cylinder 11, and a liftable compaction block 25 inside the fixed cylinder 21, a pressure rod 22 installed on the upper end of the compaction block 25, and a return spring 23 on the outside of the pressure rod 22.

[0025] Please see Figures 2-3 As shown, a set of bottom rings 116 are installed below each set of pipe trenches, and a lifting block 115 is located below the bottom ring 116, with a diameter smaller than the inner diameter of the bottom ring 116.

[0026] Please see Figure 2 and Figure 5 As shown, the inner rotating plate 111 is rotatably connected to the inner wall of the storage cylinder 11. A rotating rod 18 is installed in the middle of the upper part of the inner rotating plate 111. The upper end of the rotating rod 18 passes through the storage cylinder 11 and is connected to the rotating plate 16.

[0027] Please see Figures 1-2 As shown, multiple sets of indicators 17 are installed around the rotating plate 16, and the positions and numbers of the multiple sets of indicators 17 correspond to the positions and numbers of the multiple sets of sample tubes 112.

[0028] Please see Figures 1-2 As shown, a cap 13 is threadedly connected above the outlet 12, and a handle 14 is installed on the storage cylinder 11. After the sample is stored, the cap 13 is connected to the outlet 12 to close the outlet 12, thereby keeping the storage cylinder 11 in a closed state.

[0029] Please see Figures 1-2 As shown, a battery 114 is installed at the bottom inside the storage cylinder 11, and a controller 15 is installed at the top of the storage cylinder 11. The battery 114 is electrically connected to the electric push rod 113 through the controller 15. The controller 15 can control the lifting and lowering movement of the telescopic end of the electric push rod 113.

[0030] Please see Figure 1 , Figure 2 as well as Figure 4 As shown, the fixed cylinder 21 is internally connected to the storage cylinder 11, the pressure plate 24 is installed on the upper end of the pressure rod 22, the upper end of the return spring 23 is connected to the pressure plate 24, and its lower end is connected to the fixed cylinder 21.

[0031] Please see Figures 1-2As shown, a base plate 19 is installed below the storage cylinder 11, and multiple sets of support legs 110 are installed below the base plate 19. The support legs 110 can support the base plate 19 and prevent the base plate 19 from directly contacting the bottom surface, thus preventing moisture from entering the storage cylinder 11.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] When soil samples need to be stored, the rotating plate 16 drives the rotating rod 18 to rotate, which in turn drives the inner rotating plate 111 to rotate, rotating the empty sample tubes 112 sequentially to the area below the outlet 12 above the storage cylinder 11. Then, the controller 15 activates the electric push rod 113, which lifts the lifting block 115 upward, passing through the bottom ring 116 to push the sample tubes 112 out along the outlet 12, making it convenient for the operator to remove the sample tubes 112 for soil filling. After the sample collection is completed, the operator puts the soil-filled sample tubes 112 back into the tube slot on the inner rotating plate 111 along the outlet 12. Then, the inner rotating plate 111 is rotated again to align the next set of empty sample tubes 112 with the outlet 12. The above process is repeated to complete the classification and storage of multiple samples. When the rotating plate 16 rotates, multiple sets of indicator marks 17 corresponding to the position of the sample tubes 112 rotate synchronously, allowing the operator to visually locate the position of the sample tubes 112 through the indicator marks 17.

[0034] When the soil-filled sample tube 112 rotates with the rotating plate 16 to directly below the fixed cylinder 21, the operator presses the pressure plate 24, causing the pressure rod 22 to move downwards, so that the compaction block 25 enters the sample tube 112 to compact the soil sample, thereby eliminating internal voids and ensuring that the sample is compact and stable. During the pressure application process, the return spring 23 is compressed and stores energy. After the pressure application is completed, the spring releases its elastic potential energy, causing the compaction block 25, the pressure rod 22, and the pressure plate 24 to return to their original positions, waiting for the next work cycle. After sampling is completed, the device can be lifted and transferred using the handle 14.
