Description

Technical Field

[0001] The utility model relates to the technical field of sample storage, in particular to a soil sample storage device for soil detection. Background Art

[0002] In order to effectively reduce the interference of light on soil samples and maintain their original state, soil samples are generally stored in brown or tea-colored glass bottles. At the same time, in order to facilitate carrying and transportation, existing soil sample storage devices are usually equipped with a box that can accommodate multiple containers.

[0003] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:

[0004] In the actual operation of soil sampling, it is inevitable that some gravel will be mixed in and stored together in the container. Although most existing soil sample storage devices are equipped with elastic structures to mitigate external impact to protect the container from damage, during transportation or transfer, soil samples containing gravel may still generate a large impact force due to shaking. This impact force is very likely to cause damage to the container, especially when the gravel collides violently with the container wall, the risk of damage is even higher.

[0005] Therefore, the above technical problems need to be solved. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the present invention proposes a soil sample storage device for soil testing, which solves the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the basic technical solutions proposed by the present invention are as follows:

[0008] A soil sample storage device for soil testing comprises a box body, a box cover and two sampling bottles. The box cover is hingedly mounted on the top of the box body and locked closed by a snap-fit ​​structure to form a receiving cavity for the two sampling bottles. The device is characterized in that a rubber liner for inserting the two sampling bottles is embedded in the box body, and the top of the box body is covered with a functional component for pressing and positioning the two sampling bottles and filtering the soil samples.

[0009] The functional component includes a layer plate, and two lower hoppers extending vertically downward and having a conical structure are provided at the bottom of the layer plate. The two lower hoppers are respectively adapted to the positions of two sampling bottles, and both lower hoppers are embedded with filter nets distributed along the horizontal plane.

[0010] Preferably, the box also includes several ice boxes that can be placed inside the box, and the sides of the rubber liner are each provided with grooves for accommodating the ice boxes. The primary purpose of cryopreserving soil samples is to slow down the activity of microorganisms in the soil, reducing the decomposition of organic matter and the conversion of inorganic matter, thereby maintaining the original state of the soil samples. This is particularly important for soil samples that require long-term storage. The grooves provided on the sides of the rubber liner, in conjunction with the inner wall of the box, form a storage cavity for the ice boxes, enhancing flexibility. For soil samples that require cryopreservation, operators can place ice boxes in the grooves to create a low-temperature environment within the box.

[0011] Preferably, the filter includes a barrier that fits snugly against the inner surface of the lower hopper, with a screen fixedly attached to the bottom of the barrier. The filter is used to remove large soil clumps and gravel during soil sampling. The lower hopper has a conical structure, and during subsequent removal of the filter, the commonly used layered filter structure is prone to dropping the removed material. Preferably, the barrier can be combined with the screen to form a box structure for containing the removed material, facilitating subsequent handling of the removed material.

[0012] Preferably, it also includes four positioning accessories respectively provided at the four corners of the top of the box body, the positioning accessories include a fixing seat and a rod rotatably mounted on the top of the fixing seat, a pressure block is provided at the bottom of the rod away from the fixing seat, and the four corners of the layer plate are provided with limiting holes for the pressure blocks to be adapted and mounted. Among them, after the layer plate is placed on the top of the box body and the box cover is closed on the box body, the position can be limited by the downward pressure of the box cover. As a preference, by providing four positioning accessories and cooperating with the four limiting holes provided on the layer plate, the firmness and stability of the layer plate after positioning can be further ensured, and at the same time, the downward pressure positioning effect of the two lower hoppers on the two sampling bottles can be further ensured.

[0013] The beneficial effects of the utility model are:

[0014] The technical solution of the present invention is to embed a rubber liner for inserting two sampling bottles in the box body, and cooperate with the functional components covering the top of the box body. Under the action of two lower hoppers extending vertically downward, the two sampling bottles can form effective external positioning support. In addition, in the sampling link, the soil can be pre-screened by using the lower hopper and the filter screen to screen out sand and gravel, eliminating the risk of damage to the sampling bottle due to sample shaking.
