Description

Technical Field

[0001] The utility model belongs to the technical field of grassland biological sample storage, and particularly relates to a sample classification storage device for grassland biomass measurement. Background Art

[0002] Grassland biomass measurement is an important method for studying aspects such as ecosystem health, productivity, and carbon storage. For the classification and storage of grassland biomass samples, it is necessary to ensure the integrity and accuracy of the samples, so as to guarantee the reliability of subsequent analysis results. Generally, when grassland biological samples are stored, glass boxes are generally used for storage, which can not only reduce the extrusion of the samples, but also store smaller samples or samples that need to prevent chemical reactions.

[0003] After retrieval, in the prior art, Chinese Patent Publication No.: CN220430874U, Authorization Date: February 2, 2024, discloses a biological sample storage container including a housing, which is applied to the technical field of biological sample detection. Among them, it includes a housing, the housing is provided with a placement groove for placing a test tube containing a sample, the bottom wall of the placement groove is provided with a pop-up component for popping out the test tube; the housing is slidably connected with a pressing rod, one end of the pressing rod is connected with a limiting component, the limiting component is adapted to the pop-up component, and the limiting component is used to fix the pop-up component. Insert the test tube containing the biological sample into the placement groove, contact and press the pop-up component until the test tube is placed in the placement groove, and the limiting component fixes the pop-up component. When the test tube needs to be taken out, the limiting component is separated from the pop-up component through the pressing rod, and the pop-up component pops out the test tube, so that it is convenient for the experimenter to take out the test tube from the placement groove.

[0004] However, this device still has the following defects: Although the test tube to be taken out can be taken out and removed by the elastic reset of the pop-up spring, when the pop-up spring pops up the test tube, if the test tube contains a large amount of samples, some samples may be popped out due to the movement of the pop-up spring, and it is easy to impact some blocky soil or blocky samples into small pieces, making it difficult to conduct subsequent research. At the same time, due to the different types of grassland organisms, the required environmental temperature for storage is also different. Just relying on being placed inside the test tube, it is easy for some samples to be unable to conduct subsequent research due to non-compliant temperature. Summary of the Utility Model

[0005] In view of the above problems, the present utility model provides a sample classification storage device for measuring grassland biomass, which includes a first storage box and a second storage box. A connecting hollow block is fixedly connected between the first storage box and the second storage box. Taking-out mechanisms are arranged inside both the first storage box and the second storage box. Sample boxes are arranged above multiple said taking-out mechanisms, and the structures of multiple said taking-out mechanisms are the same;

[0006] The taking-out mechanism includes a connecting block fixedly connected to the inside of the first storage box. A push rod is slidably connected to the inside of the connecting block. A first wedge-shaped block is fixedly connected to the outside of the push rod. A placing block is fixedly connected to the upper side of the connecting block, and a communication groove is opened on the upper side of the connecting block.

[0007] Further, a first spring is fixedly connected to the inside of the connecting block. The lower end of the first spring is fixedly connected to a second wedge-shaped block.

The first spring is sleeved on the outside of the top rod. The sample box is arranged inside the placing block, and the top rod is arranged below the sample box.

[0008] Further, an extrusion plate is fixedly connected to the outside of the push rod. A second spring is fixedly connected to one side of the extrusion plate. The end of the second spring away from the extrusion plate is fixedly connected to the connecting block.

[0009] Further, a cooling box is fixedly connected to one side of the first storage box. An installation groove is opened inside the second storage box. A heating plate is fixedly connected to the inside of the second storage box, and the heating plate is arranged inside the installation groove.

[0010] Further, a connection groove is opened on one side of the first storage box close to the cooling box. A fan is fixedly connected to the inside of the first storage box, and the fan is arranged inside the connection groove.

[0011] Further, polyurethane foam and glass wool are fixedly connected to the inside of the connecting hollow block, and the inside of the connecting hollow block is sealed.

[0014] The beneficial effects of the utility model are:

[0015] 1. In the device, the first wedge block is driven to move by the push rod, so that the second wedge block moves upward, and the second wedge block is connected with the push rod, so that the push rod can push the sample box out from the inner side of the placement block, so as to facilitate the removal of the sample box. At the same time, because the upward movement of the sample box is relatively stable, the grassland biological samples inside the sample box are not easy to spill out, and the block samples are also not easy to become small pieces due to impact, so that the samples inside the sample box can be kept relatively complete.

[0016] 2. The cooling box in this device can cool the interior of the first storage box by placing dry ice inside and operating the fan, while the heating plate can maintain or heat the temperature inside the second storage box through operation, so that different types of grassland biological samples can be placed at a more suitable temperature, thereby increasing the storage time of the samples.

Detailed implementation manner

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The embodiment of the present utility model provides a sample classification storage device for measuring grassland biomass, including a first storage box 1 and a second storage box 2. Exemplarily, as Figures 1 - 5 shown.

[0027] A connecting hollow block 3 is fixedly connected between the first storage box 1 and the second storage box 2. Taking-out mechanisms 4 are arranged on the inner sides of the first storage box 1 and the second storage box 2, and sample boxes 5 are arranged above multiple taking-out mechanisms 4. The structures of the multiple taking-out mechanisms 4 are the same.

[0028] The taking-out mechanism 4 includes a connecting block 41 fixedly connected to the inner side of the first storage box 1. A push rod 43 is slidably connected to the inner side of the connecting block 41. A first wedge block 44 is fixedly connected to the outer side of the push rod 43. A placing block 42 is fixedly connected to the upper side of the connecting block 41. A communication groove 48 is opened on the upper side of the connecting block 41.

[0029] A first spring 45 is fixedly connected to the inner side of the connecting block 41. The lower end of the first spring 45 is fixedly connected to a second wedge block 47. The second wedge block 47 is arranged above the first wedge block 44. A thrust rod 46 is fixedly connected to the upper side of the second wedge block 47, and the thrust rod 46 is arranged inside the communication groove 48. The first spring 45 is sleeved on the outer side of the thrust rod 46. The sample box 5 is arranged inside the placing block 42, and the thrust rod 46 is arranged below the sample box 5.

[0030] Specifically, the sample box 5 is used to store samples. The connecting block 41 can cooperate with the placing block 42 to place the sample box 5. The connecting block 41 can connect the first wedge block 44 through the push rod 43, and install the second wedge block 47 through the first spring 45. The communication groove 48 is used to communicate the interiors of the placing block 42 and the connecting block 41;

[0031] In addition, when the push rod 43 moves, it can push the second wedge block 47 through the first wedge block 44, causing the second wedge block 47 to drive the ejector rod 46 to move upward. When the ejector rod 46 moves upward, it can lift the sample box 5, facilitating the staff to take out the sample box 5. Since the structures of multiple taking-out mechanisms 4 are the same, the specific working process will not be elaborated here.

[0032] A pressing plate 121 is fixedly connected to the outer side of the push rod 43. A second spring 122 is fixedly connected to one side of the pressing plate 121. The end of the second spring 122 away from the pressing plate 121 is fixedly connected to the connecting block 41, as Figures 1 - 5 shown.

[0033] A cooling box 71 is fixedly connected to one side of the first storage box 1. An installation groove 72 is formed in the inner side of the second storage box 2. A heating plate 73 is fixedly connected to the inner side of the second storage box 2, and the heating plate 73 is arranged inside the installation groove 72.

[0034] A connection groove 91 is formed in the side of the first storage box 1 close to the cooling box 71. A fan 92 is fixedly connected to the inner side of the first storage box 1, and the fan 92 is arranged inside the connection groove 91.

[0035] Specifically, the second spring 122 can drive the pressing plate 121 and the push rod 43 to reset through its own elasticity after the push rod 43 is pushed, making the reset of the push rod 43 and the first wedge block 44 more convenient;

[0036] In addition, the inside of the cooling box 71 can be used to store dry ice, so as to cool the samples stored inside the first storage box 1 through the low temperature of the dry ice, thereby playing a role in extending the storage time of the samples inside the first storage box 1. The heating plate 73 can heat the inside of the second storage box 2 through its own operation, so that the temperature inside the second storage box 2 can be maintained at a suitable temperature, thereby extending the storage time of the samples inside the second storage box 2, enabling different types of grassland biological samples to be classified and stored for a long time;

[0037] In addition, the fan 92 can, through its own operation, blow the cold air released by the cooling box 71 into the interior of the first storage box 1 more smoothly, enabling more cold air to enter the interior of the first storage box 1 and making the temperature inside the first storage box 1 lower.

[0038] The inner side of the connecting hollow block 3 is fixedly connected with a polyurethane foam 81 and a glass wool 82, and the interior of the connecting hollow block 3 is hermetically arranged, as Figures 1 - 5 shown.

[0039] One side of each of the first storage box 1 and the second storage box 2 is movably hinged with a hinge door 10 through a hinge. A hollow groove 111 is formed on one side of each of the two hinge doors 10, and a temperature detector 112 is arranged on the inner side of each of the two hinge doors 10, and the temperature detector 112 is arranged inside the hollow groove 111.

[0040] The inner side of the placing block 42 is fixedly connected with a rubber pad 61. The rubber pad 61 is arranged on the outer side of the sample box 5, and one side of the cooling box 71 away from the first storage box 1 is fixedly connected with a sponge pad 62.

[0041] Specifically, the polyurethane foam 81 and the glass wool 82 can play a heat insulation effect, so that the temperatures inside the first storage box 1 and the second storage box 2 are not easily affected by each other. The interior of the connecting hollow block 3 is hermetically arranged, enabling the connecting hollow block 3 to have a better heat insulation function;

[0042] In addition, the two hinge doors 10 can play a role in closing the first storage box 1 and the second storage box 2. At the same time, the two temperature detectors 112 can detect the temperatures inside the first storage box 1 and the second storage box 2, facilitating the staff to observe and record the temperatures inside the first storage box 1 and the second storage box 2 in real time;

[0043] In addition, the rubber pad 61 can play a role in protecting and positioning the sample box 5. Due to the placement of dry ice for cooling inside the cooling box 71, the surface temperature of the cooling box 71 will be relatively low, while the sponge pad 62 can play a role in shielding the cooling box 71, reducing the possibility of the cooling box 71 causing frostbite to the hands of the staff.

[0044] A sample classification and storage device for measuring grassland biomass proposed by an embodiment of the present utility model has the following working principle: When this device is in use, grassland biological samples can be placed inside the sample box 5, and the sample box 5 can be placed on the upper side and inside the placement block 42 of the connection block 41. Then, the sample box 5 can be classified and stored according to the types of samples inside the sample box 5. Samples that need to be stored at low temperature are placed inside the first storage box 1, while samples that need to be stored at normal temperature or high temperature are placed inside the second storage box 2. Then, the inside of the first storage box 1 is cooled by the dry ice placed inside the cooling box 71, and the temperature inside the second storage box 2 is controlled or heated by the operation of the heating plate 73.

[0045] When it is necessary to take out the sample box 5, the staff can open the hinge door 10 and push the push rod 43. When the push rod 43 moves, it will drive the first wedge block 44 to move together. The movement of the first wedge block 44 will push and squeeze the second wedge block 47, causing the second wedge block 47 to move upward and smoothly eject the sample box 5 through the ejector rod 46. Then, the staff can smoothly take out the sample box 5. After that, the push rod 43 and the first wedge block 44 will be reset by the elasticity of the second spring 122, and the second wedge block 47 will be reset by the elasticity of the first spring 45.

[0046] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
