Description

Technical Field

[0001] This utility model relates to the field of land assessment auxiliary equipment technology, and in particular to a sample storage box for land economic assessment. Background Technology

[0002] In land economic assessment, the cleanliness of soil sample tube storage directly affects the accuracy of test data, and consequently, the reliability of assessment results. Currently, most commonly used soil sample tube storage devices are open-frame structures or sealed boxes without internal partitions. When retrieving a single sample tube, all tubes inside the box must be completely exposed to the external environment, making them susceptible to contamination from airborne dust and sample residues accidentally touched during operation. Furthermore, retrieving inner sample tubes requires moving outer tubes, which can easily lead to soil debris falling off and cross-contamination, especially for samples requiring trace contaminant testing, directly causing detection errors. In addition, the large opening of the box during retrieval allows external moisture and impurities to enter, further affecting the storage environment of unretrieved sample tubes, making it difficult to meet the requirement of zero-contamination storage of soil samples.

[0003] Therefore, it is necessary to invent a sample storage box for land economic assessment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing storage boxes require all sample tubes inside the box to be completely exposed to the external environment when taking out or putting in a single sample tube, making them susceptible to contamination from dust in the air and sample residues accidentally touched during operation. Therefore, this invention provides a sample storage box for land economic assessment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sample storage box for land economic assessment, comprising a storage box assembly, the storage box assembly comprising a box body with a slot on its surface, a plurality of storage slots being formed around the slot, a cavity communicating with the slot and storage slots being provided inside the box body, a sliding groove being formed between the slot and the storage slots, a retrieval mechanism for non-contact sample retrieval being provided inside the cavity and the slot, a box cover assembly being snapped onto the box body for individually retrieving the sample in cooperation with the retrieval mechanism, and an adjustment component for adjusting the retrieval position of the retrieval mechanism being slidably provided on the box cover assembly.

[0006] As a further description of the above technical solution: the extraction mechanism includes a fixed tube rotatably connected to the cavity via a bearing seat, the outer wall of the fixed tube is provided with a first sliding limiting groove, a sliding tube is slidably sleeved on the outside of the fixed tube through the first sliding limiting groove and a sliding block, the fixed tube and the sliding tube are also connected by a spring, an extraction plate is fixedly connected to the sliding tube, and a cross groove is provided at the top.

[0007] As a further description of the above technical solution: the box cover assembly includes a box cover body with marking lines on its surface, and a rotating disk is rotatably connected to the inner side of the box cover body via a bearing. The rotating disk is provided with an extraction hole and a pointer.

[0008] As a further description of the above technical solution: a sliding hole is also provided in the center of the rotating disk, and a protrusion is fixedly connected to the sliding inner wall.

[0009] As a further description of the above technical solution: the adjustment component includes an adjustment rod with a second sliding groove on its surface. The adjustment rod is slidably connected to the rotating disk through the cooperation of the second sliding limiting groove and the protrusion. A cross-shaped locking block is fixedly connected to the bottom of the adjustment rod, and an adjustment handle is fixedly connected to the top.

[0010] As a further description of the above technical solution: the storage box assembly also includes a sample bottle placed in the storage slot, and a handle with a connection hole on its surface is fixedly connected to the side of the box body.

[0011] As a further description of the above technical solution: the size of the storage slot matches the sample bottle, the size of the extraction hole matches the sample bottle, and the size of the extraction plate matches the sliding groove.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. This utility model, by setting up a storage box assembly, a take-out mechanism, a box cover assembly, and an adjustment assembly, allows for efficient handling during actual use. When taking out or placing a single sample, only the target sample bottle is exposed through the take-out hole, while the other sample bottles remain within the double-enclosed space of the box and the rotating disk. This completely isolates the sample bottles from airborne dust and operational residues. The take-out process is achieved by lifting the sample via a take-out plate, eliminating the need for staff to touch other sample bottles. This avoids the problem of soil debris falling off due to moving outer samples in traditional methods. It is particularly suitable for high-precision testing of samples such as trace heavy metals and pesticide residues, ensuring the accuracy of the test data.

[0013] 2. The extraction mechanism of this utility model is guided by spring buffer and sliding limit groove. The movement of the sliding tube and adjusting rod is smooth and without shaking. When the extraction plate lifts the sample bottle, the force is even, avoiding damage and leakage caused by tilting or collision of the sample bottle. The storage slot is precisely matched with the size of the sample bottle. Combined with the box lid for sealing and fixing, the sample bottle does not shift during transportation, further reducing the probability of sample damage. Attached Figure Description

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-7The present invention provides a technical solution: a sample storage box for land economic assessment, comprising a storage box assembly 1, the storage box assembly 1 comprising a box body 11 with a slot 12 on its surface, a plurality of storage slots 13 around the slot 12, a cavity 14 communicating with the slot 12 and the storage slots 13 inside the box body 11, a sliding groove 15 between the slot 12 and the storage slots 13, the storage box assembly 1 further comprising a sample bottle 16 placed in the storage slot 13, a handle 17 with a connection hole 18 fixedly connected to the side of the box body 11, a retrieval mechanism 2 for non-contact retrieval of the sample being provided inside the cavity 14 and the slot 12, a box cover assembly 3 being snapped onto the box body 11 for individually retrieval of the sample in cooperation with the retrieval mechanism 2, and an adjustment component 4 for adjusting the retrieval position of the retrieval mechanism 2 being slidably provided on the box cover assembly 3.

[0018] Therefore, when moving the box 11, the operator can move the box 11 as a whole through the handle 17, or connect the carrying strap or rope to the handle 17 through the connecting hole 18, so that the box 11 can be carried on the back, which is convenient for moving the box 11 during field operations.

[0019] Specifically, such as Figures 3-5 As shown, in order to realize the individual handling of sample vials 16, this utility model is provided with a take-out mechanism 2. The take-out mechanism 2 includes a fixed tube 21 rotatably connected to the cavity 14 through a bearing seat. A first sliding limiting groove 22 is provided on the outer wall of the fixed tube 21. A sliding tube 23 is slidably sleeved on the outside of the fixed tube 21 through the first sliding limiting groove 22 and the sliding block 24. The fixed tube 21 and the sliding tube 23 are also connected by a spring 25. A take-out plate 26 is fixedly connected to the sliding tube 23, and a cross groove 27 is provided on the top.

[0020] Specifically, such as Figure 6 and Figure 7 As shown, the box cover assembly 3 includes a box cover body 31 with marking lines 32 on its surface. A rotating disk 33 is rotatably connected to the inner side of the box cover body 31 via a bearing. The rotating disk 33 is provided with a take-out hole 34 and a pointer 35. A sliding hole 36 is also provided in the center of the rotating disk 33. A protrusion 37 is fixedly connected to the sliding inner wall. The adjustment assembly 4 includes an adjustment rod 41 with a second sliding groove 15 on its surface. The adjustment rod 41 is slidably connected to the rotating disk 33 through the cooperation of the second sliding limit groove 42 and the protrusion 37. A cross-shaped locking block 43 is fixedly connected to the bottom of the adjustment rod 41, and an adjustment handle 44 is fixedly connected to the top. The size of the storage slot 13 matches the sample bottle 16, the size of the take-out hole 34 matches the sample bottle 16, and the size of the take-out plate 26 matches the sliding groove 15.

[0021] Therefore, in actual use, the sample bottle 16 containing the soil sample is first placed into the storage slot 13 on the surface of the box body 11, and the corresponding mark is affixed to the marking line 32. The size of the storage slot 13 matches the sample bottle 16 to ensure that the sample bottle 16 is stable and upright. Then, the box cover body 31 is closed and locked in place. At this time, the rotating disk 33 on the inside of the box cover covers the surface of the box body 11. The removal hole 34 on the rotating disk 33 is not initially aligned with any storage slot 13. All sample bottles 16 are in a closed and isolated state to avoid external contamination. According to the position of the sample bottle 16 to be removed, referring to the marking line 32 on the surface of the box cover body 31, the adjusting handle 44 is pushed down to move the adjusting rod 41 and the cross block 43 downward. At the same time, the sliding tube 23 is moved downward and the spring 25 is compressed until the removal plate 26 is removed from the sliding tube. The moving groove 15 slides out and moves into the cavity 14. Then, the operator rotates the adjusting handle 44 to drive the adjusting rod 41 and the rotating disk 33 to rotate. During the rotation of the rotating disk 33, the pointer 35 on the edge of the rotating disk 33 points to the mark line 32 synchronously with the rotation. When the pointer 35 is aligned with the mark line 32 corresponding to the target sample bottle 16, the rotation stops. At this time, the extraction hole 34 on the rotating disk 33 is just aligned with the top of the target sample bottle 16. At the same time, the extraction plate 26 also rotates to the bottom of the target sample bottle 16. Then, the operator pulls the adjusting handle 44 upward, and the spring 25 elastically resets and pushes the sliding tube 23 upward. The extraction plate 26 lifts the target sample bottle 16 through the extraction hole 34 of the rotating disk 33 and extends it out of the box. At this time, the staff can directly take away the sample bottle 16 without having to touch other sample bottles 16.

[0022] After the sample is removed, the operator presses the adjusting handle 44 again to make the removal plate 26 fall back to the bottom of the sliding groove 15. Then, the adjusting handle 44 and the adjusting rod 41 are rotated again to drive the sliding tube 23 and the removal plate 26 to rotate, and drive the rotating disk 33 to rotate so that the pointer 35 and the removal hole 34 return to the initial position, that is, the removal hole 34 is misaligned with all the storage grooves 13. The box cover body 31 continues to close the box 11, and the unremoved sample bottles are still in an isolated state, completing the entire removal and placement process.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
