Description

Technical Field

[0001] The utility model relates to the technical field of sampling, in particular to a sampling device for detecting pesticide residues in agricultural products. Background Art

[0002] In order to increase the output of agricultural products, pesticides are generally sprayed on agricultural products. However, pesticides not only kill pests, but are also toxic to humans. If too much pesticide is sprayed on agricultural products, too much pesticide will remain on the surface and inside the agricultural products. If people accidentally ingest the agricultural products, it will cause certain damage to the human body. In order to study the impact of pesticide spraying amount on pesticide residues on agricultural products, it is necessary to test the pesticide residues on agricultural products. Before testing, sampling needs to be carried out.

[0003] At present, the sampling process of agricultural products is divided into two steps. The first step is to pick the agricultural products from the vines at the production site, and the second step is for the experimenters to bring the picked agricultural products back to the laboratory for cutting and grouping, and then test the cut agricultural products. At present, in the process of sampling and testing agricultural products, in addition to sampling the surface of the agricultural products, it is also necessary to sample the inside of the agricultural products to detect whether there are any pesticide residues inside the agricultural products. Moreover, the inside of the agricultural products can be tested and compared with the skin of the agricultural products. However, when inspecting the inside of the agricultural products, the traditional sampling method is mostly for the experimenters to manually cut the agricultural products to obtain the internal samples. However, the traditional cutting method is mostly for the experimenters to hold the agricultural products with one hand and use a knife with the other hand to cut them multiple times to obtain the innermost samples of the agricultural products. This process takes a long time to cut and the samples are easily contaminated during the cutting process. Summary of the invention

Four through grooves 11 are provided on the circumferential surface of the main chamber 1, an external thread 12 is provided on the outer circumferential surface of the main chamber 1, a swivel 2 is rotatably installed on the outer circumferential surface of the main chamber 1, a limiting ring groove 21 is provided on the upper end circumferential surface of the swivel 2, a connecting ring 22 is rotatably installed inside the limiting ring groove 21, four first grooves 221 are evenly provided on the circumferential surface of the connecting ring 22, a connecting shaft 3 is fixedly installed inside the first groove 221, a first connecting plate 31 is rotatably installed on the circumferential surface of the connecting shaft 3, and a rotating shaft 32 is rotatably installed on the upper end of the first connecting plate 31. The two ends of the rotating shaft 32 are rotatably installed with limit blocks 4, and the two ends of the limit blocks 4 are provided with second grooves 41. The rotating shaft 32 is rotatably installed inside the second groove 41. The upper end of the inner part of the through groove 11 is rotatably installed with a passive shaft 52, and a second connecting plate 51 is rotatably installed on the circumferential surface of the passive shaft 52. The lower end of the second connecting plate 51 is rotatably installed with a circular shaft 5, and the circular shaft 5 is rotatably installed inside the second groove 41.

[0028] By adopting the above technical solution, the sampling devices on the market can only take the agricultural products 6 from the branches or vines, and for the next step of cutting and sampling, the experimenters need to cut manually so that the experimenters can get the desired samples; and the current sampling of agricultural products 6 requires the epidermis and a part of the inside of the agricultural products 6 to detect whether the agricultural products 6 have absorbed pesticides through the roots and stems, resulting in residual pesticides inside the agricultural products 6; and when sampling the inside of the agricultural products 6, the experimenters need to use the cutting device to cut the agricultural products 6 multiple times so as to get the innermost part of the agricultural products 6, and the process is During the process, the agricultural product 6 needs to be turned over many times, which is not convenient for subsequent inspection; when in use, the rotating ring 2 is rotated, and the rotating ring 2 moves upward. During the upward movement of the rotating ring 2, it can move synchronously with the connecting ring 22. At this time, the connecting ring 22 will push the first connecting plate 31 to rotate clockwise, and the first connecting plate 31 will drive the lower end of the limit block 4 to move outward during the rotation process, and the limit block 4 will drive the second connecting plate 51 to rotate counterclockwise during the outward movement. At this time, the limit block 4 slides out from the inside of the through groove 11; then, the experimenter puts the agricultural product 6 into the inside of the main chamber 1, and one end of the agricultural product 6 is aligned with the storage ring The upper end surfaces of the agricultural products 6 are fitted together, and then, in order to prevent the agricultural products 6 from shaking during the subsequent cutting process, the rotating ring 2 is rotated in the opposite direction. At this time, the rotating ring 2 will move downward. At this time, the rotating ring 2 will rotate counterclockwise with the first connecting plate 31, and the first connecting plate 31 will slide out of the through-groove 11 with the limiting block 4 until the limiting block 4 and the outer side of the agricultural products 6 are fitted together, and the rotating ring 2 stops moving. At this time, under the action of the limiting block 4, the agricultural products 6 are in the center position of the storage ring 13; then the experimenter allows the cutting column 7 to move upward. At this time, the top of the cutting column 7 will pass through the through hole 131 and connect with the lower end of the agricultural products 6 The cutting tool on the top of the cutting column 7 will cut the center of the agricultural product 6, so that the center of the agricultural product 6 enters the interior of the cutting column 7, and the sampling operation is completed. After the sampling operation is completed, the agricultural product 6 that has been sampled can be separated from the limiting block 4 according to the above steps, and then the agricultural product 6 can be taken out. With the cooperation of the above structure, the sampling of the agricultural product 6 can be completed at one time, and the innermost sample of the agricultural product 6 can be obtained without damaging the skin of the agricultural product 6. Moreover, with the cooperation of the above structure, the sample can be obtained quickly, which saves the cutting time of the experimenter and avoids the damage of the sample.

[0029] Specifically, Figures 1 to 4As shown, it includes a main body chamber 1 and a cutting column 7, and the cutting column 7 is slidably installed inside the main body chamber 1, characterized in that: a storage ring 13 is fixedly installed at the lower end of the main body chamber 1, and agricultural products 6 are placed on the storage ring 13. A plurality of limit slides 14 are fixedly installed on the circumferential surface of the lower end of the main body chamber 1, and a plurality of convex slide grooves 71 are opened on the circumferential surface of the cutting column 7, and the limit slide 14 is slidably installed inside the convex slide grooves 71. A connector 72 is fixedly installed at the lower end of the cutting column 7, and a container 8 is rotatably installed inside the connector 72.

[0030] By adopting the above technical solution, when sampling agricultural products 6 on the market, in order to ensure the freshness of the samples, the experimenters will directly go to the experimental site to take samples. Since it is outdoors, the samples may be contaminated, which may easily affect the data in the subsequent detection. When in use, the container 8 is rotated and connected with the connector 72, so that the cutting column 7 and the container 8 are in a through state, and then the cutting column 7 moves upward to cut the agricultural products 6. At this time, the cut part of the agricultural products 6 will enter the interior of the cutting column 7. Since the cutting column 7 and the container 8 are in a through state, the cut sample will directly enter the interior of the container 8, and then the cutting column 7 is separated from the agricultural products 6. At this time, the container 8 is rotated, and the container 8 will be separated from the connector 72, and then the top opening of the container 8 can be sealed with a threaded cap. With the cooperation of the above structure, the sample can enter the interior of the storage container 8 at the first time, avoiding the sample from being exposed to the air for a long time, avoiding the contamination of the sample by dust in the experimental field, and ensuring that the sample will not be damaged in subsequent experiments.

[0031] Working principle: First, rotate the swivel 2, the swivel 2 moves upward, the swivel 2 allows the first connecting plate 31 to rotate clockwise, and then the first connecting plate 31 slides out of the interior of the through groove 11 with the limit block 4, and the limit block 4 rotates counterclockwise with the second connecting plate 51.

[0032] Next, the agricultural products 6 are placed into the main chamber 1 and are fitted with the upper end surface of the storage ring 13 .

[0033] After completion, the above steps are reversed to allow the inner side of the limiting block 4 to slide out of the through groove 11 to fix the agricultural product 6 .

[0034] Then the cutting column 7 moves upward to sample the agricultural product 6. After the cutting column 7 completes the cutting, the sample will enter the interior of the container 8. The container 8 is rotated to separate the container 8 from the connector 72 and the container 8. Then the experimenter can seal the top of the container 8.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
