Description

Technical Field

[0001] This utility model relates to the field of agricultural product sampling technology, and in particular to a sampling structure for pesticide residues in agricultural products. Background Technology

[0002] Agricultural products refer to primary products derived from agriculture, namely plants, animals, microorganisms and their products obtained from agricultural production activities. Their scope covers all kinds of products from fields, pastures, and waters to those before primary processing. They are an important source of human food and industrial raw materials, as well as a core component of the agricultural economy. In the quality and safety testing of agricultural products, pesticide residue testing is one of the key links, and the accuracy and representativeness of sampling directly affect the reliability of the test results.

[0003] During the use of existing sampling equipment, it was found that the sampling paper needs to be inserted into the sampling equipment, which is a cumbersome process with unstable connections. When the sample is removed, it may leave sample residue on the surface of the equipment. The existing patent (publication number: CN222353545U) relates to the field of pesticide residue sampling structure installation technology, and discloses a surface pesticide residue sampling structure for agricultural product testing. It includes a first outer shell, a control button installed on the top right side of the first outer shell, thirteen equally spaced placement slots on the top front of the first outer shell, a carrying plate installed on the left side of the first outer shell, a display panel embedded in the bottom front of the first outer shell, and a cover plate installed on the top side of the first outer shell. The cover plate is linked to an automatic pressing mechanism via a transmission rod at its bottom. The automatic pressing mechanism includes a clamping plate embedded in the front of the placement slots. A guide plate is horizontally installed inside the first outer shell. This surface pesticide residue sampling structure for agricultural product testing allows for easy operation through the automatic pressing mechanism, and the sampling paper fixing method linked to the cover plate simplifies the sampling steps, making the installation and removal of the sampling paper more convenient and faster.

[0004] To address the aforementioned issues, existing patents offer solutions. However, existing sampling structures are insufficient to penetrate deep into agricultural products, only obtaining surface or shallow samples. This results in unrepresentative sampling that fails to reflect the overall pesticide residue situation of agricultural products. Furthermore, the sampling process involves multiple steps of sampling, transfer, and collection, which can introduce external impurities into the samples due to contact with the outside air, the operator's hands, or the surface of tools, affecting the accuracy of the test results.

[0005] Therefore, a sampling structure for pesticide residues in agricultural products is proposed. Utility Model Content

[0018] 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.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A pesticide residue sampling structure for agricultural products includes a base 1, and a support frame 2, a sampling mechanism 3 and a fixing mechanism 4 are provided on the top of the base 1. The sampling mechanism 3 includes an electric lifting rod 31, which is fixedly connected to the top of the support frame 2. The output rod of the electric lifting rod 31 passes through the support frame 2 and is fixedly connected to a fixed frame 32. A micro motor 33 is fixedly connected to the bottom of the inner side of the fixed frame 32. A sampling cylinder 34 is fixedly connected to the bottom of the fixed frame 32. The output shaft of the micro motor 33 passes through the sampling cylinder 34 and is fixedly connected to a spiral blade 35. The surface of the output shaft of the micro motor 33 is rotatably connected to the inner wall of the fixed frame 32 and the sampling cylinder 34 through bearings. A discharge pipe 36 is connected to the top right side of the sampling cylinder 34. A collection bottle 37 is connected to the surface of the discharge pipe 36 through threads. The collection bottle 37 is made of transparent material.

[0020] In this embodiment: by setting up a base 1, a support frame 2, a sampling mechanism 3, and a fixing mechanism 4, the base 1 provides a supporting foundation for the entire device during use. The support frame 2 supports and fixes the sampling mechanism 3. The sampling mechanism 3 allows for convenient sampling deep into the interior of agricultural products, thereby improving the representativeness of the sampling and reflecting the overall pesticide residue status of the agricultural products. Furthermore, the sample is collected directly without contact with external impurities during the sampling process, thus improving the accuracy of subsequent test results. The fixing mechanism 4 can quickly and stably fix the sampled agricultural product, preventing displacement or shaking during the sampling process, thus bringing convenience to the sampling work.

[0021] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the fixing mechanism 4 includes a placement platform 41, the bottom of which is fixedly connected to the top of the base 1. Fixing blocks 42 are fixedly connected to all four sides of the top of the placement platform 41, and pneumatic telescopic rods 43 are fixedly connected to the four fixing blocks 42 on the side away from the center of the top of the placement platform 41.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the output rod of the pneumatic telescopic rod 43 passes through the fixed block 42 and is fixedly connected to the clamping plate 44. The bottom of the clamping plate 44 is slidably connected to the top of the placement platform 41. A rubber pad 45 is fixedly connected to the side of the clamping plate 44 away from the pneumatic telescopic rod 43.

[0023] Specifically, such as Figure 4 As shown, the fixed block 42 has a through hole 5 on the side away from the clamping plate 44, which is used to cooperate with the pneumatic telescopic rod 43. The output rod surface of the pneumatic telescopic rod 43 is slidably connected to the inner wall of the through hole 5.

[0024] In this embodiment: by setting up a placement platform 41, a fixing block 42, a pneumatic telescopic rod 43, a clamping plate 44, a rubber pad 45, and a through hole 5, in use, the agricultural product is placed on the placement platform 41, and then the four pneumatic telescopic rods 43 are activated respectively, so that the output of the four pneumatic telescopic rods 43 extends and drives the four clamping plates 44 to move closer to the agricultural product until the rubber pads 45 on the four clamping plates 44 are in close contact with the agricultural product, thus completing the fixation of the agricultural product and preventing the agricultural product from shifting or shaking during the sampling process, thereby bringing convenience to the sampling work. The setting of the rubber pad 45 can not only increase the fixing friction, but also prevent the clamping plate 44 from pinching the agricultural product. The setting of the through hole 5 allows the output rod of the pneumatic telescopic rod 43 to pass through the fixing block 42 for telescopic output.

[0025] Specifically, such as Figure 5 As shown, the top of the support frame 2 is provided with a through hole 6 for use with the electric lifting rod 31, and the output rod surface of the electric lifting rod 31 is slidably connected to the inner wall of the through hole 6.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, two limit rods 7 are fixedly connected to the top of the fixed frame 32. The top of the two limit rods 7 extends through to the top of the support frame 2. The top of the support frame 2 has sliding holes 8 on both sides that cooperate with the two limit rods 7 respectively. The surface of the limit rod 7 is slidably connected to the inner wall of the sliding hole 8.

[0027] In this embodiment: by setting the through hole 6, the output rod of the electric lifting rod 31 can pass through the support frame 2 for telescopic output; by setting the limiting rod 7, the fixed frame 32 can be guided and limited to avoid shaking; by setting the sliding hole 8, the limiting rod 7 can pass through the support frame 2 for up and down sliding.

[0028] Specifically, such as Figure 1 , Figure 2As shown, the two sides of the bottom of the support frame 2 are fixedly connected to the two sides of the top of the base 1. The right side of the support frame 2 is fixedly connected to a controller 9 that works with the sampling mechanism 3 and the fixing mechanism 4. The controller 9 is electrically connected to the sampling mechanism 3 and the fixing mechanism 4.

[0029] Specifically, such as Figure 1 , Figure 2 As shown, an anti-slip pad 10 is fixedly connected to the bottom of the base 1. The anti-slip pad 10 is made of silicone material.

[0030] In this embodiment: by setting the controller 9, the sampling mechanism 3 and the fixing mechanism 4 can be easily operated. By setting the anti-slip pad 10, the friction can be increased, thereby improving the stability of the base 1.

[0031] Working principle: In use, the agricultural product is first placed on the placement platform 41. Then, the controller 9 activates the four pneumatic telescopic rods 43, causing the outputs of the four pneumatic telescopic rods 43 to extend and drive the four clamping plates 44 towards the agricultural product until the rubber pads 45 on the four clamping plates 44 are tightly attached to the agricultural product, thus fixing the agricultural product and preventing displacement or shaking during sampling, thereby facilitating the sampling work. Before sampling, the transparent collection bottle 37 is threadedly connected to the discharge pipe 36 on the right side of the sampling cylinder 34 to ensure a seal. During sampling, the controller 9 sets the descent stroke of the electric lifting rod 31 and the speed of the micro motor 33, causing the output rod of the electric lifting rod 31 to move downward along the through hole 6 of the support frame 2, driving the fixing frame 32 and the bottom... The sampling cylinder 34 descends synchronously, and the limiting rod 7 at the top of the fixed frame 32 slides synchronously along the sliding hole 8 of the support frame 2, ensuring that the sampling cylinder 34 vertically cuts into the agricultural product. At the same time, the micro motor 33 starts, and its output shaft drives the spiral blade 35 inside the sampling cylinder 34 to rotate at high speed. The spiral blade 35 cuts the agricultural product tissue, and the cut sample is conveyed upward along the spiral pattern of the spiral blade 35. Then, it is directly collected into the collection bottle 37 through the discharge pipe 36. The operator can observe the sample volume through the transparent collection bottle 37. After sampling is completed, the controller 9 controls the electric lifting rod 31 to drive the sampling cylinder 34 to rise and reset, the micro motor 33 is turned off, and the collection bottle 37 is unscrewed to obtain the sample. Throughout the process, the sample is isolated from the outside world from cutting and sampling to collection, avoiding contamination and thus improving the accuracy of subsequent test results.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
