Description

Technical Field

[0001] The present invention relates to the basic working field of soil detection technology, and in particular to a device for storing soil samples. Background Art

[0002] The collected soil samples carry rich information on soil properties and environmental characteristics, and play an irreplaceable role in analyzing soil environmental conditions and changing trends in different historical stages. Storing soil samples collected in different historical periods is an indispensable basic resource for soil quality monitoring and scientific research in soil science-related fields, and is also an important guarantee for testing the fairness, scientificity and accuracy of soil survey results. The longer the soil samples are preserved and the more they are, the greater their role. my country began the third national soil census in 2022. This is an important survey of national conditions and national strength, which is of great significance to the level of soil resource protection and utilization. According to relevant documents of the National Third Census Office, this census has been fully scientifically demonstrated, and more than 3 million sample points have been set up across the country, with at least one soil sample collected at each sample point. How to efficiently store and manage these soil samples has become a major technical problem that needs to be solved urgently.

[0003] In the related art, glass bottles are generally used to hold soil samples for long-term storage. Among them, the mobile compact cabinet storage method is relatively common. By placing the glass bottles containing soil samples on the layered shelves of the compact cabinet, multiple rows of glass bottles containing soil samples are placed on each shelf. This storage method occupies a relatively small area, but because the compact cabinet slides on the track, the weight of the entire compact cabinet and the sample is concentrated on the narrow track, which has high requirements for the track, and the track, pulley, etc. are prone to failure during operation; at the same time, the compact cabinet will cause certain vibrations during operation, which may damage the soil samples and even cause the glass bottles to break. In order to avoid accidents caused by the tipping of the compact cabinet and completely damage the samples, in order to prevent the center of gravity of the compact cabinet from being too high, the height of the compact cabinet is low, and the number of shelves is small. When the number of soil samples increases, its advantage of less space is not obvious, and it even occupies more space, making the storage efficiency low; in addition, since the entire weight (sample weight + compact cabinet weight itself) is added to the local position, the local stress is extremely large, the load requirements for the floor are extremely high, special reinforcement is required, and the cost is high. Another way to preserve soil samples for a long time is the fixed shelf storage method, which is to place soil samples on the shelf boards of fixed shelves, with multiple rows of soil samples placed on each shelf board. Although this method can avoid setting up tracks, when storing and retrieving soil samples in a narrow space such as a sample rack, it is necessary to take out the soil samples outside and put them back after taking out the soil samples inside. This not only increases the workload and reduces the storage and retrieval efficiency, but also easily confuses the sample storage location. In order to overcome this shortcoming, the spacing between the upper and lower partitions can be increased by 2 times the height of the sample bottle, and the number of rows of sample bottles can be reduced accordingly, so that the storage capacity is reduced by at least 50%. At the same time, this method occupies a relatively large area. Obviously, the existing fixed shelf storage method is difficult to take into account both capacity efficiency and storage and retrieval efficiency. Summary of the invention

[0004] In view of this, the present invention provides a method and device for storing soil samples.

[0005] Specifically, the present invention is achieved through the following technical solutions: According to a first aspect of the present invention, there is provided a device for storing a soil sample, the device for storing a soil sample comprising: Multiple parallel rows of sample racks, each row of sample racks includes individual racks connected in sequence on the side. Each individual rack is provided with multiple sheet racks in the vertical placement direction and perpendicular to the arrangement direction of the row of sample racks. The sheet rack is formed by connecting two side vertical columns and one middle vertical column through diagonal tension bars. Two back-to-back connected minimum storage units are arranged at a certain height interval between two sheet racks. Each minimum storage unit is used to store a predetermined number of sample bottles filled with soil samples. The minimum storage unit is in an open C shape, with both the top and bottom of the minimum storage unit hollowed out, and the hollowed-out area at the bottom is smaller than that at the top; The minimum storage unit includes a tray for placing multiple soil samples and a C-shaped support arm supporting the tray. The tray stores a soil sample group composed of multiple soil samples. The inner diameter of the C-shaped support arm is smaller than the outer diameter of the tray, and the outer diameter of the C-shaped support arm is slightly larger than the outer diameter of the tray. The outer diameter of the C-shaped support arm has an upright enclosure several centimeters high. The tray enters and exits the C-shaped support arm horizontally from the opening direction of the C-shaped support arm. After the tray is taken out to a position not restricted by the space of the row of sample racks, the target sample is retrieved and stored from the tray; Two minimum storage units form a pair of minimum sample units back to back. The left and right sides of multiple pairs of minimum storage units are fixed to adjacent sheet racks at a certain height interval to form a unit rack. Multiple unit racks are connected in sequence by sharing sheet racks to form an individual rack. Multiple individual racks are connected in sequence by sharing straight vertical columns to form a row of sample racks.

[0006] Optionally, the C-shaped support arm includes: a rear enclosure, a left enclosure, a right enclosure, a rear support arm, a left support arm, and a right support arm. The rear enclosure is located on the opposite side of the C-shaped opening in the vertical direction, the left enclosure is located on the left side of the C-shaped opening in the vertical direction, and the right enclosure is located on the right side of the C-shaped opening in the vertical direction; The rear support arm, the left support arm, and the right support arm are located at the bottom of the minimum storage unit. The rear support arm and the rear enclosure, the left support arm and the left enclosure, and the right support arm and the right enclosure respectively form an L-shaped structure. The rear support arm, the left support arm, and the right support arm form a hollow space smaller than the space for placing the sample bottle.

[0007] Optionally, the tray is made of weather-resistant steel with a thickness of 1.5 mm, and a grid for dividing the placement positions of various sample bottles is arranged inside the tray.

[0008] Optionally, the rear enclosure, the left enclosure, and the right enclosure have the same height, approximately 5 cm.

[0009] Optionally, the rear support arm, the left support arm, and the right support arm have the same width on the horizontal plane, approximately 5 cm; and the thickness is 3 mm.

[0010] Optionally, the rear support arm, left support arm, right support arm, rear enclosure, left enclosure, and right enclosure are made of weather-resistant steel with a thickness of 3 mm.

[0011] Optionally, the rear support arm and rear enclosure, the left support arm and left enclosure, and the right support arm and right enclosure are respectively two sides of the L-shaped component, and the rear support arm, left support arm and right support arm form a hollow space smaller than the maximum projection area of ​​the tray for placing sample bottles, and the rear enclosure, left enclosure and right enclosure form a hollow space larger than the maximum projection area of ​​the tray for placing sample bottles.

[0012] The device for storing soil samples in this technical solution forms a sample rack group by arranging multiple sample rack rows in parallel. Each sample rack row includes monomer racks fixedly connected to the side. Each monomer rack is provided with multiple sheet racks in the vertical direction, perpendicular to the arrangement direction of the sample rack row. The sheet rack is formed by connecting two side columns and one middle column with diagonal braces. At regular intervals in height between two sheet racks, two back-to-back connected minimum storage units are provided. Each minimum storage unit is used to store a predetermined number of sample bottles filled with soil samples. The minimum storage unit is in an open C shape, with both the top and bottom of the minimum storage unit being hollowed out, and the hollowed-out area at the bottom is smaller than that at the top. The minimum storage unit includes a tray for placing multiple soil samples and a C-shaped support arm supporting the tray. The tray stores a soil sample group composed of multiple soil samples. The inner diameter of the C-shaped support arm is smaller than the outer diameter of the tray, and the outer diameter of the C-shaped support arm is slightly larger than the outer diameter of the tray. The outer diameter of the C-shaped support arm has an upright enclosure several centimeters high. The tray enters and exits the C-shaped support arm horizontally from the opening direction of the C-shaped support arm. After the tray is taken out to a position not restricted by the space of the sample rack row, the target sample is retrieved or stored from the tray. Two minimum storage units form a minimum sample unit pair back-to-back. Multiple minimum sample unit pairs are fixed in layers to adjacent sheet racks to form a unit rack. Multiple unit racks are sequentially connected by sharing sheet racks to form a monomer rack. Multiple monomer racks are sequentially connected in the side direction to form a sample rack row. In this way, by using the minimum storage unit to store sample bottles, when retrieving and placing sample bottles, it is not necessary to retrieve and place other sample bottles one by one multiple times, thus effectively improving the access efficiency of soil samples. Further, the sample group access method is adopted. First, a minimum storage unit is formed by a tray for placing a soil sample group and a C-shaped support arm supporting the tray, storing a group of samples composed of multiple soil sample collections. The tray enters and exits the C-shaped support arm horizontally from the opening direction of the C-shaped support arm. When the tray is taken out to a position not restricted by the narrow space of the sample rack, the target soil sample is retrieved or stored from the tray. Then, two minimum storage units are back-to-back, that is, the C-shaped opening directions of the two minimum storage units are opposite to form a minimum sample unit pair. Multiple minimum sample storage unit pairs are fixed in layers to adjacent sheet racks to form a unit rack, and then multiple unit racks are sequentially connected by sharing sheet racks to form a monomer sample rack that can operate independently and store thousands of samples. Moreover, by connecting multiple monomer sample racks with connectors (such as bolts), a sample rack row can be formed, which can improve stability and sample storage capacity. Furthermore, to improve the anti-tipping property of the sample rack in the C-shaped opening direction, multiple sample rack rows can be arranged at a certain interval to form a sample rack row group, and the tops of adjacent sample racks are bridged by a rigid material (such as a steel bar).It has at least the following advantages: It avoids the need to access multiple samples one by one to access a single sample, improving the access efficiency; since the tray for storing samples enters and exits the "C"-shaped support arm horizontally, the height of each layer of the sample rack only needs to be slightly higher than the sample bottle, and with the same height of the sample rack, the number of layers of the sample rack is much more, significantly improving the storage capacity; there is no need to lay fixed facilities such as tracks, and there is no rigid connection between the sample rack and the ground, greatly improving the portability of the sample rack, and the individual sample racks can be freely combined, greatly improving the flexibility of the spatial layout of the sample rack; unlike the traditional track-intensive cabinet method, it has a very small ground load-bearing, but the entire ground bears the load, greatly avoiding the risk of ground (floor) damage caused by excessive local ground stress, and at the same time reducing the construction cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0017] In the related art, whether it is the method of using mobile compact filing cabinets or fixed shelves to store soil samples, for fixed shelves, when accessing soil samples, it is necessary to move, remove and replace non-target samples, resulting in low access efficiency and extremely easy to cause confusion in the storage locations of soil samples. In addition, for mobile compact filing cabinets, since the mobile compact filing cabinets are set to slide on the tracks, the tracks are prone to failures during operation, reducing the reliability of the use of mobile compact filing cabinets and also resulting in less improvement in storage efficiency with the occurrence of failures; at the same time, the vibration caused during the operation of the tracks is likely to damage the soil samples, reducing the reliability of soil sample storage; moreover, considering the safety of the center of gravity of the mobile compact filing cabinets, the height of the mobile compact filing cabinets is relatively low, requiring a higher load on the floor, thus resulting in higher costs.

[0018] In this embodiment, a fixed-assembled-tray type soil sample storage device is proposed. First, a tray for placing a group of soil samples and a C-shaped support arm supporting the tray form a minimum sample storage unit, that is, the minimum storage unit. A group of samples composed of multiple sample sets is stored in this unit. Using the tray as the access unit, the tray enters and exits the C-shaped support arm horizontally from the opening direction of the C-shaped support arm. When the tray is taken out and not restricted by the narrow space of the sample rack, the target sample is accessed from the tray. Then, two minimum sample storage units are combined back to back to form a pair of minimum sample storage units. Multiple pairs of minimum sample storage units are fixed layer by layer to adjacent sheet racks to form a unit rack, and multiple unit racks are connected in sequence by sharing sheet racks to form a single unit rack that can operate independently and store thousands of samples; further, in order to improve stability and sample storage capacity, multiple single unit racks are connected by connectors (such as bolts) to form a row of sample racks; furthermore, in order to improve the anti-tipping property of the sample rack in the C-shaped opening direction, multiple rows of sample racks can also be arranged at a certain interval to form a group of sample rack rows, and the tops of adjacent rows of sample racks are bridged by a hard material (such as a steel bar).

[0019] See Figure 1, embodiments of the present invention provide a device for storing soil samples. The device includes: a plurality of sample rack rows 11 arranged in parallel, each sample rack row 11 includes monomer racks 12 sequentially connected on the side, each monomer rack 12 is provided with a plurality of upright and parallel sheet racks 13 in the vertical placement direction. The sheet rack is formed by connecting 2 side columns and 1 middle column through diagonal braces. Between every two sheet racks 13, there are a plurality of minimum sample storage unit pairs composed of two minimum sample storage units 14 (minimum storage units) with a certain interval in the vertical direction (height) and overlapping in the horizontal position (projection). Each minimum sample storage unit 14 is used to store a predetermined number of sample bottles filled with soil samples. The minimum sample storage unit 14 is in an open C shape, with both the top and bottom of the minimum sample storage unit 14 hollowed out, and the hollowed-out area at the bottom is smaller than that at the top; The minimum sample storage unit 14 includes a tray for placing a plurality of soil samples and a C-shaped support arm supporting the tray. The tray stores a soil sample group composed of a plurality of soil samples. The inner diameter of the C-shaped support arm is smaller than the outer diameter of the tray, and the outer diameter of the C-shaped support arm is slightly larger than the outer diameter of the tray. The outer diameter of the C-shaped support arm has an upright enclosure with a preset height (for example, 1 - 10 cm). The tray enters and exits the C-shaped support arm horizontally from the opening direction of the C-shaped support arm. After the tray is taken out to a position not restricted by the space of the sample rack row, the target soil sample is retrieved and stored from the tray; Two minimum sample storage units 14 form a minimum sample unit pair back to back. A plurality of minimum storage unit pairs are fixed layer by layer to adjacent sheet racks to form a unit rack. A plurality of unit racks are sequentially connected in the side direction through the way of sharing sheet racks to form a monomer rack 12, and a plurality of monomer racks 12 are sequentially connected in the side direction to form a sample rack row 11.

[0020] In this embodiment, each minimum sample storage unit is independent of each other, and each independent minimum sample storage unit stores a certain number of sample bottles.

[0021] In this embodiment, the sheet rack for fixing and supporting the minimum sample storage unit is assembled by two L-shaped side columns, one L-shaped middle column, through the left and right support arms, left and right enclosures of the minimum sample storage unit, and diagonal braces.

[0022] In this embodiment, the middle columns of two sheet racks are connected together by the rear support arm, rear enclosure of the minimum sample storage unit, and diagonal braces.

[0023] In this embodiment, as an optional embodiment, the tray member of the minimum sample storage unit is a tray made of weathering steel with a thickness of 1.5 mm, and a grid for dividing the placement positions of various sample bottles is arranged inside the tray.

[0024] In this embodiment, for the collected soil samples, the mass is generally between 500 and 800 g. As an alternative embodiment, a sample bottle with a capacity of 750 ml is selected. The grid array formed by the minimum sample storage units is 4×5, that is, the number of sample bottles stored in each minimum sample storage unit is 4×5 = 20 sample bottles. That is, in the direction parallel to the arrangement direction of the sample rack rows, 4 sample bottles are placed in sequence without isolation between the 4 placed sample bottles, which is convenient for taking out or putting back the sample bottles. In the direction perpendicular to the arrangement direction of the sample rack rows, 5 sample bottles are placed in sequence, and there is an isolation belt between each sample bottle.

[0025] In this embodiment, as an alternative embodiment, the internal dimensions of the minimum sample storage unit are: 465 mm x 365 mm x 55 mm, where 465 mm is the length in the direction perpendicular to the arrangement direction of the sample rack rows, 365 mm is the length in the direction parallel to the arrangement direction of the sample rack rows, and 55 mm is the height.

[0026] In this embodiment, when using the minimum sample storage unit to store sample bottles, when taking out or putting back the sample bottles, only the array of the sample bottle to be taken out or put back in the minimum sample storage unit needs to be determined. For this array, only the sample bottles need to be taken out or put back in the direction parallel to the arrangement direction of the sample rack rows, without taking out or putting back the sample bottles in other arrays in the minimum sample storage unit, and even less need to take out or put back all the sample bottles on the sheet rack corresponding to the layer of the sample bottle to be taken out or put back. This can avoid the defects caused by directly placing the sample bottles on the shelf, such as: if the height of the layer of the sample rack where the sample bottle is placed is less than twice the height of the sample bottle, when taking the sample bottle inside, all the sample bottles outside need to be taken out and put back once, which not only increases the workload but also easily causes the sample bottles to be misplaced and damaged; if the height between the shelves is greater than twice the height of the sample bottle, when taking the sample bottle inside, although it is not necessary to take out and put back all the sample bottles outside once, it significantly increases the storage space and greatly reduces the space efficiency of storing soil samples.

[0027] In this embodiment, as an alternative embodiment, the minimum sample storage unit is a U-shaped storage groove, and two back-to-back U-shaped storage grooves are respectively located on the single racks fixedly connected back to back.

[0028] In this embodiment, by setting the minimized storage unit as a "U-shaped storage groove", two U-shaped storage grooves are combined back to back to form a pair of U-shaped storage grooves. Multiple pairs of U-shaped storage grooves are connected in sequence to form a U-shaped storage groove layer of the sheet rack. Multiple U-shaped storage groove layers are stacked in the vertical space and extended in the horizontal direction to form a sample rack row for storing soil samples composed of single racks fixedly connected back to back. Multiple sample rack rows are reasonably arranged to form the device for storing soil samples in this embodiment.

[0029] In this embodiment, as an alternative embodiment, the minimum sample storage unit (U-shaped storage slot) includes: a rear enclosure, a left enclosure, a right enclosure, a rear support arm, a left support arm, and a right support arm, where The rear enclosure, the left enclosure, and the right enclosure form a hollow space of the minimum sample storage unit for placing sample bottles; In the vertical direction, the rear enclosure is located on the opposite side of the opening, the left enclosure is located on the left side of the opening in the vertical direction, and the right enclosure is located on the right side of the opening in the vertical direction; The rear support arm, the left support arm, and the right support arm are located at the bottom of the minimum sample storage unit. The rear support arm and the rear enclosure, the left support arm and the left enclosure, and the right support arm and the right enclosure respectively form an L-shaped structure. The rear support arm, the left support arm, and the right support arm form a hollow space smaller than the hollow space for placing sample bottles.

[0030] In this embodiment, as an alternative embodiment, three sides of the four sides of the "U-shaped storage slot" are provided with vertical enclosures and horizontal support arms, one side perpendicular to the top is open, and both the top and the bottom are hollowed out. Among them, the hollowed-out area of the bottom is smaller than that of the top, so as to form support arms at the bottom to support the sample bottles.

[0031] In this embodiment, the enclosure opposite to the opening surface is the rear enclosure, the support arm opposite to the opening surface is the rear support arm, the enclosure on the left side of the opening surface is the left enclosure, the support arm on the left side of the opening surface is the left support arm, the enclosure on the right side of the opening surface is the right enclosure, and the support arm on the right side of the opening surface is the right support arm. The enclosures and the support arms are an integral whole that are tightly connected together.

[0032] In this embodiment, as an alternative embodiment, the device further includes: Buffer strips (not shown in the figure), which are arranged inside the minimum sample storage unit, and multiple buffer strips are respectively pasted on the rear enclosure, the left enclosure, the right enclosure, the rear support arm, the left support arm, and the right support arm.

[0033] In this embodiment, the inner size of the minimum sample storage unit pasted with buffer strips has a preset redundant space after placing the sample bottles, that is, the depth formed by the three enclosures along the opening direction is about 5 mm larger than the depth of the corresponding array-placed sample bottles along the opening direction, and the inner distance between the left and right enclosures is about 5 mm larger than the depth of the corresponding array-placed sample bottles along the left and right directions.

[0034] In this embodiment, the rear enclosure, the left enclosure, and the right enclosure have the same height. As an alternative embodiment, the height of the rear enclosure is 5 cm.

[0035] In this embodiment, the width of the rear support arm in the direction perpendicular to the parallel arrangement direction is the same as the widths of the left support arm and the right support arm in the parallel arrangement direction. As an alternative embodiment, the width of the rear support arm is 5 cm and the thickness is 3 mm.

[0036] The rear support arm and the rear enclosure, the left support arm and the left enclosure, and the right support arm and the right enclosure respectively form an L-shaped structure, and the rear support arm, the left support arm, and the right support arm form a hollow space smaller than the hollow space for placing the sample bottle.

[0037] In this embodiment, during the actual manufacturing process, as an alternative embodiment, three 50 mm * 50 mm "L" steels with a thickness of 3 mm are assembled together to form a "U-shaped storage groove".

[0038] In this embodiment, when manufacturing the assembled intensive sample rack, that is, the device for storing soil samples, in this embodiment, several short "L" steel bars and diagonal bracing steel sheets are used to connect 3 long "L" steel bars into a "sheet rack"; several short "L" steel bars and diagonal bracing steel sheets are used to connect the middle "L" steel columns of 2 "sheet racks" to form a double-sheet rack structure with multiple layers of "U-shaped storage groove pairs"; according to the connection method for forming the double-sheet rack structure, "single racks" are sequentially added to form a multi-sheet rack structure with multiple layers of "U-shaped storage groove pairs", and each layer has n - 1 "U-shaped storage groove pairs", where n is the number of single-sheet racks. As an alternative embodiment, taking 5 single-sheet rack structures as an example, each layer has 4 "U-shaped storage groove pairs" and 4 "U-shaped storage grooves" to form a single unit rack; multiple single-unit sample racks are assembled together through connecting bolts to form a sample rack row; the sample rack rows are arranged in parallel to form the device for storing soil samples.

[0039] In this embodiment, as an alternative embodiment, the device further includes: A controller (not shown in the figure), which is used to construct the correspondence between the sample rack row, the placement position of the sample rack row, and the sample collection area. When storing the sample bottles containing soil samples, according to the collection area of the soil samples, it determines the sample rack row for storing the sample bottles and the smallest storage unit of this sample rack row. In the direction perpendicular to the arrangement direction of the sample rack rows, two nameplates including the collection area identifier, the sample rack row identifier, the smallest storage unit identifier, the sample bottle identifier, and the collection time identifier for storing this sample bottle are generated in the direction from near to far from the sample rack row. On the upper side of the smallest storage unit with an opening, there is also a nameplate slot. One nameplate is attached to the sample bottle, and after storing the sample bottle, the other nameplate is placed in the nameplate slot.

[0040] In this embodiment, by placing the nameplate in the nameplate slot, when the sample bottle is taken out for processing and no longer needs to be stored, it is convenient to update the nameplate placed in the nameplate slot.

[0041] In this embodiment, when it is necessary to take out the sample bottle, as another alternative embodiment, the controller is further configured to: receive the query information of the sample bottle to be taken out input by the user, where the query information includes one or any combination of the collection area identifier, the sample rack identifier, the minimum storage unit identifier, the sample bottle identifier, and the collection time identifier, and determine the sample rack placement position of the sample bottle to be taken out according to the query information, so as to take out the sample bottle from the determined sample rack placement position.

[0042] The device for storing soil samples in this embodiment uses the minimum storage unit to store the sample bottles. When taking in and out the sample bottles, it is only necessary to determine the array of the sample bottles to be taken in and out in the minimum storage unit. For this array, it is only necessary to take in and out the sample bottles in the direction parallel to the arrangement direction of the sample rack row, without taking in and out the sample bottles in other arrays in the minimum storage unit, and even less necessary to take in and out all the sample bottles on the shelf board corresponding to the layer of the sample bottle to be taken in and out, thereby effectively improving the access efficiency of the soil samples. Further, a tray for placing a group of soil samples and a U-shaped support arm supporting the tray form a minimum storage unit, storing a group of samples composed of multiple soil sample sets. The tray enters and exits the U-shaped support arm horizontally from the opening direction of the U-shaped support arm. When the tray is taken out and not restricted by the narrow space of the sample rack, the target soil sample is taken in and out from the tray; then, two minimum storage units are combined back to back to form a minimum storage unit pair, and multiple minimum sample storage unit pairs are fixed to the same vertical column layer by layer to form a unit rack, and then multiple unit racks are connected in sequence by sharing the vertical column to form a single sample rack that can operate independently and store thousands of samples; moreover, in order to improve the stability and the sample storage capacity, multiple single sample racks are connected by connectors to form a sample rack row; furthermore, in order to improve the anti-tipping property of the sample rack in the U-shaped opening direction, multiple sample rack rows can be arranged at a certain interval to form a sample rack row group, and the tops of adjacent sample racks are bridged by a hard material. It has at least the following advantages: avoiding the need to access multiple samples in order to access a certain sample, improving the access efficiency; at the same time, because the tray for storing the samples enters and exits the U-shaped support arm horizontally, the height of the sample rack only needs to be slightly higher than the sample bottle. Under the same sample rack height, the number of layers of the sample rack is much more, significantly improving the storage capacity; further, there is no need to lay fixed facilities such as tracks, and there is no rigid connection between the sample rack and the ground, greatly improving the portability of the sample rack, and the single sample racks can be freely combined, greatly improving the flexibility of the sample rack layout; compared with the traditional track-intensive cabinet method with only a small ground load, in this embodiment, the entire ground bears the load, greatly avoiding the risk of damage to the ground (floor slab) caused by excessive local stress on the ground, and at the same time reducing the construction cost, so as to achieve high-capacity storage of soil samples and improve the efficiency of accessing samples.
