Description

Technical Field

[0001] This utility model relates to the technical field of agricultural product testing and sampling, specifically to an agricultural product pesticide residue testing and sampling device. Background Technology

[0002] Agricultural products refer to primary products derived from planting, forestry, animal husbandry, and fisheries, such as plants obtained in agricultural activities, like rice, sorghum, and peanuts. In order for agricultural products to grow better, pesticides need to be sprayed on them in appropriate amounts to effectively prevent and control diseases and pests. However, excessive pesticide residues can harm the human body, so it is necessary to use testing and sampling devices to test and sample agricultural products.

[0003] As disclosed in announcement number CN219245022U, a sampling device for detecting pesticide residues in agricultural products includes a fixing head, a sampling bucket, a cutting blade, and a fixing component. The fixing component includes a fixing ring, a clamping component, a limiting component, and a spring-loaded component. The fixing ring is used to fix large agricultural products, such as melons; the clamping component can slide to adjust its size to clamp small agricultural products of different sizes; the limiting component is used to restrict the clamping component and fix it to a stable clamping state; the spring-loaded component can spring the clamping component back after sampling for easy reuse. By setting an adjustable clamping component, it is convenient to clamp agricultural products of various sizes, increasing the practicality of the device. This solves the problem that the size of the fixing blade in existing devices is fixed, which can only be used to fix agricultural products of the same size, thus reducing the detection range of the device.

[0004] However, existing technologies have problems such as being inconvenient to carry, and when sampling plants, only one sample can be obtained at a time, resulting in limited sample capacity. This makes it inconvenient to compare and test samples, and it is also inconvenient to sample agricultural products in batches. Furthermore, the operation of handling the extracted samples is quite inconvenient. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a sampling device for detecting pesticide residues in agricultural products. Utility Model Content

[0034] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-8 The present invention provides the following technical solution.

[0036] Example 1: To address the problems of inconvenience in carrying existing technologies, and the limited sample capacity (only one sample can be obtained at a time when sampling plants), making comparative testing difficult, this example provides a pesticide residue detection sampling device for agricultural products. The device comprises a lower sampling box 1, an upper sampling box 2, sampling ports 3, and a sorting plate 4. The upper sampling box 2 is attached to the upper end of the lower sampling box 1, and the sorting plate 4 runs through the middle of the upper sampling box 2. The upper end of the sorting plate 4 is attached to the inner wall of the upper part of the upper sampling box 2. The sorting plate 4 is engaged with the middle of the lower sampling box 1, and multiple sampling ports 3 are provided on both the front and rear sides of the sorting plate 4. The sampling ports 3 are fixedly connected to the front and rear ends of the lower sampling box 1 and the upper sampling box 2, respectively. Figure 1 , Figure 2 and Figure 4 As shown, the device is carried by the hand-held connecting plate 5, and the sampling port 3 is provided with multiple sets. Moreover, the classification plate 4 can divide the space inside the lower sampling box 1 and the upper sampling box 2 into multiple independent cavities, which facilitates the classification and storage of multiple samples, thereby enabling the samples to be detected and compared, making the detection results more accurate.

[0037] Example 2: To address the problems existing in the prior art, this example provides the following technical solution: a sampling device for detecting pesticide residues in agricultural products, comprising a connecting plate 5, a movable support 6, a first spring 7, and a cutter 8. The upper end of the upper sampling box 2 is provided with the connecting plate 5, and the movable support 6 is fixedly connected to both the left and right sides of the lower end of the connecting plate 5. The outer surface of the upper end of the movable support 6 is fitted with the first spring 7, and the movable support 6 and the upper sampling box 2 form a sliding structure. The movable support 6 is fixedly connected to the side of the cutter 8, and the movable support 6 drives the cutter 8 to form a lifting structure within the upper sampling box 2. The cutter 8 is respectively fitted against the inner walls at the front and rear ends of the upper sampling box 2. Figure 3 , Figure 5 and Figure 6 As shown, after arriving at the sampling location, remove the plug (not shown in the diagram) that is engaged at the end of the sampling port 3 away from the lower sampling box 1 and the upper sampling box 2. After removing the plug, insert the agricultural product to be sampled directly into the sampling port 3. The agricultural product extends into the lower sampling box 1 and the upper sampling box 2 through the sampling port 3. Then, press down on the connecting plate 5. The connecting plate 5 causes the movable bracket 6 to slide between itself and the upper sampling box 2. The connecting plate 5 compresses the first spring 7, causing the first spring 7 to undergo elastic deformation. The movable bracket 6 then... The moving cutter 8 moves downward to cut and sample the agricultural products inside the lower sampling box 1 and the upper sampling box 2 through the sampling port 3. The cut agricultural product samples fall directly into the cavity inside the lower sampling box 1 for collection. Then, the connecting plate 5 is released directly. At this time, the first spring 7 returns to its elastic deformation and pushes the connecting plate 5 upward. The connecting plate 5, together with the movable bracket 6, drives the cutter 8 to move upward and reset, thus completing the sampling work. After the sampling is completed, the plug is locked at the far end of the sampling port 3 to prevent the sample from falling out of the sampling port 3.

[0038] Example 3: To address the problems of inconvenience in batch sorting and sampling of agricultural products and the inconvenience in handling the extracted samples in existing technologies, this example provides a pesticide residue detection and sampling device for agricultural products. The device includes protrusions 9, fixing grooves 10, and connecting mechanisms 11. Protrusions 9 for positioning are fixedly connected to the left and right sides of the lower end of the upper sampling box 2, and the upper sampling box 2 drives the protrusions 9 to insert into the fixing grooves 10. The fixing grooves 10 are located at the upper end of the lower sampling box 1, and the fixing grooves 10 and protrusions 9 are arranged in a one-to-one correspondence. The connecting mechanisms 11 are symmetrically arranged at the left and right ends of the lower sampling box 1. The sampling box includes a fixed block 12, a hollow cylinder 13, a second spring 14, a movable block 15, and a positioning plate 16. The connecting mechanism 11 drives the upper sampling box 2 to form a disassembly structure above the lower sampling box 1. Hollow cylinders 13 are fixedly connected to both the left and right sides of the upper end of the lower sampling box 1. A second spring 14 is installed inside the hollow cylinder 13, and the movable end of the second spring 14 is fixedly connected to the movable block 15. The movable block 15 and the hollow cylinder 13 form a left-right sliding structure. The movable block 15 is fixedly connected to the lower end of the positioning plate 16. A fixed block 12 for limiting the position is inserted into the upper end of the positioning plate 16. The fixed blocks 12 are respectively fixedly connected to the left and right sides of the lower end of the upper sampling box 2. Figure 2 , Figure 7 and Figure 8 As shown, when it is necessary to take a sample for testing, the positioning plate 16 can be pulled outwards directly. The positioning plate 16 drives the movable block 15 to slide in the hollow cylinder 13. At this time, the movable block 15 squeezes the second spring 14, causing the second spring 14 to undergo elastic deformation. The upper end of the positioning plate 16 is separated from the fixed block 12, thereby releasing the limit between the upper sampling box 2 and the lower sampling box 1. Then, the upper sampling box 2 is pulled upwards, and the upper sampling box 2 drives the protrusion 9 to move out of the fixed groove 10, which facilitates the disassembly of the upper sampling box 2 and the lower sampling box 1. Then, the collected sample can be taken out for testing.
