Description

Technical Field

[0001] This utility model relates to the field of wheat detection technology, specifically a portable sampling and storage device. Background Technology

[0002] In the safety monitoring of grain crops such as wheat, the detection of mycotoxins is a crucial step. The first step in the detection is to collect samples in the field or warehouse. Currently, sampling personnel usually need to carry multiple tools, such as probes, shovels, sample bags, labels, and notebooks, which is a cumbersome operation.

[0003] CN218725404U discloses a wheat sampler, "comprising a first handle and a second handle with rotatable ends; the first handle has a first semi-circular arc-shaped sampling shell at its end, and also includes a second semi-circular arc-shaped sampling shell, the first semi-circular arc-shaped sampling shell being hollow inside with its opening facing inward, and a collection bag on its back." The user clamps the first and second semi-circular arc-shaped sampling shells on the device to the joint of the wheat stalk, grips the first and second handles firmly to remove the stalk joint, and then shakes the device a few times, causing the stalk joint to enter the collection bag. However, in the detection of mycotoxins, different wheat samples need to be tested in batches to obtain accurate values. This device uses only one collector, storing all the wheat in one collector, leading to cross-contamination between samples and preventing the acquisition of more accurate values.

[0004] Based on this, a portable sampling and storage device is now provided that can eliminate the drawbacks of existing devices. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In one embodiment, such as Figures 1-4 As shown, a portable sampling and storage device includes a collection box 1, a placement chamber 8 is provided at the upper end of the collection box 1, and a plurality of stabilizing frames 10 are arranged in an array in the placement chamber 8, with a plurality of placement slots 11 correspondingly opened on the surface of each stabilizing frame 10. Each longitudinally corresponding placement slot 11 has a slidable acquisition component inside it; The acquisition component includes an acquisition tube 6, with a limiting block 12 fixedly connected to the upper end of the acquisition tube 6. A sliding groove 13 is provided on the inner side of the limiting block 12. A pair of clamping plates 14 are symmetrically slidably arranged on the inner side of the sliding groove 13. Several springs 15 are arranged on the adjacent side of the clamping plate 14 and the sliding groove 13. The other end of the spring 15 is fixedly connected to the inner side of the sliding groove 13. A pull ring 16 is slidably arranged on both sides of the limiting block 12. One end of each pull ring 16 passes through the limiting block 12 and is fixedly connected to one end of the adjacent clamping plate 14. In this embodiment, when it is necessary to pick up or put down the collection tube 6, the operator pulls the two pull rings 16 outwards at the same time. The pull rings 16 drive the clamping plate 14 to slide in the slide groove 13 and compress the spring 15, so that the space between the two clamping plates 14 increases. At this time, the wheat ears can be put into the collection tube 6. After releasing the pull rings 16, the rebound force of the spring 15 pushes the clamping plate 14 to move inwards, automatically clamping the wheat ears. Then, pulling the wheat ears can scrape the wheat into the collection tube 6.

[0022] In one embodiment, such as Figure 3 As shown, a freezing chamber 18 is provided at the bottom of the collection box 1. Several ventilation holes 9 are arrayed at the upper end of the freezing chamber 18. Ice packs for low-temperature preservation are placed inside the freezing chamber 18. The cold air released by the ice packs is evenly diffused into the placement chamber 8 above through the ventilation holes 9, providing a continuous and stable low-temperature environment for the sample in the collection tube 6, effectively inhibiting the activity of microorganisms in the sample, maintaining the freshness of the sample and the accuracy of the detection. The ventilation holes 9 ensure that the cold air is evenly distributed.

[0023] In one embodiment, such as Figure 3 As shown, a sealing cover 7 is hinged to one side of the lower end of the collection box 1, and a top cover 5 is hinged to the upper end of the collection box 1. The sealing cover 7 is used to seal the freezer compartment 18, which facilitates the removal, placement and replacement of ice packs; the top cover 5 is used to seal the placement compartment 8 to prevent cold air leakage and external pollutants from entering. This double-cover design realizes independent sealing and management of different functional compartments, which improves the practicality and heat preservation effect of the device.

[0024] In one embodiment, such as Figure 3 As shown, the inner side of the collection box 1 is provided with an insulation layer, which is made of rigid polyurethane foam filled inside the collection box 1. The rigid polyurethane foam has an extremely low thermal conductivity, which can effectively block the heat exchange between the inside and outside of the box. In conjunction with the freezing chamber 18, it significantly prolongs the low temperature maintenance time, reduces the frequency of ice pack consumption, and ensures that the sample is always in a suitable low temperature environment during long-term field sampling.

[0025] In one embodiment, such as Figure 1 As shown, a fixing component is provided on one side of the collection box 1. The fixing component allows the entire sampling and storage device to be firmly fixed to the sampling personnel or other carriers, which facilitates movement and operation in complex environments, frees up the operator's hands, and improves the flexibility and efficiency of sampling work.

[0026] In one embodiment, such as Figure 1 As shown, the fixing component includes a fixing ring 3, and several fixing rings 3 are provided and fixedly connected to one side of the collection box 1. A waist belt 2 is provided through the fixing ring 3. The multiple fixing rings 3 are evenly distributed on one side of the collection box 1. The waist belt 2 passes through all the fixing rings 3, which firmly binds the collection box 1 to the waist of the sampling personnel, so that the device can be carried by the person, which makes it convenient for the sampling personnel to move freely in the field or warehouse and carry out continuous sampling operations.

[0027] In one embodiment, such as Figure 1As shown, both ends of the waist belt 2 are provided with Velcro 4. Velcro 4 provides a quick, convenient and infinitely adjustable connection method. Sampling personnel can easily adjust the tightness of the waist belt 2 according to their own waist size to ensure comfortable and secure wearing, while greatly improving the speed of putting on and taking off, and adapting to the needs of users with different body types.

[0028] In one embodiment, such as Figure 1 As shown, the waist belt 2 is made of elastic fiber material. The elastic fiber material gives the waist belt 2 good elasticity, which can adapt to the natural changes in waist circumference when the human body bends over, walks and other movements, providing continuous and unrestricted fit and fixation, significantly improving the comfort of wearing for a long time.

[0029] The above embodiment discloses a portable sampling and storage device. During sampling, the operator pulls the pull ring 16 outward to open the clamp 14, allowing wheat ears to be placed into the collection tube 6. After releasing the pull ring 16, the spring 15's rebound force pushes the clamp 14 inward, automatically clamping the wheat ears. Pulling the wheat ears then scrapes them into the collection tube 6. After sampling, the collection tube 6 containing the sample is placed back into the placement slot 11 of the stabilizer 10. Ice packs in the freezing compartment 18 at the bottom of the collection box 1 release cold air upward through the vents 9, providing a low-temperature environment for the placement compartment 8. The insulation layer made of rigid polyurethane foam effectively maintains the low temperature inside the box. The operator can secure the collection box 1 to their waist using the waist belt 2 and fixing ring 3, adjusting the tightness using Velcro 4. The elastic fiber waist belt 2 ensures comfortable wear. The top cover 5 and sealing cover 7 independently seal the placement compartment 8 and freezing compartment 18, respectively, ensuring a stable and pure sample storage environment.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
