Technical Field
[0001] This utility model relates to the field of agricultural product testing technology, and in particular to a pesticide residue detection device for organic agricultural products. Background Technology
[0002] Today, people are paying increasing attention to health and food safety, and the market demand for organic agricultural products is also rising. Organic agricultural products are produced in strict accordance with strict organic agricultural standards, prohibiting or restricting the use of chemically synthesized pesticides and fertilizers, striving for naturalness, safety and environmental protection. However, given the complexity of the agricultural production environment and the illegal activities of some businesses, organic agricultural products still face the potential risk of pesticide residue pollution. Therefore, it is necessary to test the surface residues of fruits and vegetables after harvesting. However, the traditional method of sampling and testing in test tubes not only requires many tools, which increases the trouble for the testing personnel, but also reduces the testing efficiency. Moreover, it is extremely inconvenient to carry a large number of tools when going out for testing. In addition, most common pesticide residue testing devices are bulky and heavy, with poor portability, making it difficult to achieve rapid and convenient testing in diverse scenarios, which is not conducive to the effective control of agricultural product quality at all stages. Utility Model Content
[0003] The main objective of this invention is to provide a pesticide residue detection device for organic agricultural products, which can effectively solve the problems in the background technology.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0027] Please see Figure 1-4 This utility model provides a technical solution:
[0028] A pesticide residue detection device for organic agricultural products includes a base frame 1. Baffles 2 are fixedly connected to the upper left and upper right parts of the base frame 1. Each baffle 2 has a left-right through-hand grip opening 3 at the upper left end. A crushing module structure 4 is fixedly connected to the lower inner wall of the base frame 1. A base platform 5 is fixedly connected to the lower inner wall of the base frame 1. A placement groove 6 is opened in the middle of the upper end of the base platform 5. A detector dish structure 7 is movably placed in the middle of the upper end of the base platform 5. The lower part of the detector dish structure 7 is located in the placement groove 6. A display screen 8 is fixedly connected to the front of the upper end of the base platform 5. An operation keyboard 9 is provided in the front of the upper end of the display screen 8.
[0029] In this embodiment, the crushing module structure 4 includes a load-bearing frame 41. The lower left and lower right portions of the load-bearing frame 41 are fixedly connected to the lower left and lower right portions of the inner lower wall of the crushing module structure 4, respectively. An internal threaded slot 42 is opened in the middle of the upper end of the load-bearing frame 41. The load-bearing frame 41 is threadedly connected to an agricultural product crushing box 43 through the internal threaded slot 42. The lower part of the agricultural product crushing box 43 is located in the internal threaded slot 42. An outer frame 44 is fixedly connected to the upper part of the outer surface of the agricultural product crushing box 43. The right end of the outer frame 44 extends to the top of the agricultural product crushing box 43. A crushing component 45 is fixedly connected to the middle of the upper end of the outer frame 44. The lower part of the crushing component 45 is located inside the agricultural product crushing box 43. A filter nozzle is fixedly connected to the upper right end of the agricultural product crushing box 43. 46. Several fine filter holes 47 are opened at the right end of the filter frame nozzle 46. The crushing component 45 includes a servo motor 451. The servo motor 451 is fixedly connected to the upper end of the outer frame 44. The output end of the servo motor 451 passes through the middle of the upper end of the outer frame 44 and is fixedly connected to a fixing rod 452. The lower end of the fixing rod 452 is movably connected to the agricultural product crushing box 43 through a bearing. A circular block 453 is inserted and fixedly connected to the lower part of the outer surface of the fixing rod 452. Three crushing blades 454 are fixedly connected to the outer surface of the circular block 453. The three crushing blades 454 are arranged in a ring array. The three crushing blades 454 are located in the lower part of the agricultural product crushing box 43. The three crushing blades 454 do not contact the inner wall of the agricultural product crushing box 43.
[0030] Through the above scheme: the servo motor 451 is started to work, and the servo motor 451 drives the fixed rod 452 to rotate, so that the circular block 453 and the three crushing blades 454 arranged in a ring array rotate at high speed in the agricultural product crushing box 43. This can cut and crush the agricultural products placed in the box. The crushed material moves to the right under the action of gravity to the filter frame nozzle 46. The fine filter holes 47 of the filter frame nozzle 46 can filter out larger particles of impurities, resulting in relatively fine and uniform material. The load-bearing frame 41 and its internal threaded slots 42 provide stable support for the agricultural product crushing box 43 and a convenient installation method, which is convenient for disassembly and cleaning. The outer frame 44 provides a stable installation base for the crushing component 45, ensuring that the crushing process proceeds smoothly. Thus, the crushing module structure 4 can efficiently pre-process agricultural products into a state suitable for subsequent testing, ensuring the accuracy and reliability of pesticide residue detection.
[0031] In this embodiment, the detector dish structure 7 includes a detector dish box 71. An electrochemical sensor 72 and an optical sensor 73 are fixedly connected to the left and right sides of the inner wall of the detector dish box 71, respectively. The electrochemical sensor 72 and the optical sensor 73 are located together in the lower part of the inner wall of the detector dish box 71. An upper cover 74 is movably inserted into the upper end of the detector dish box 71. The detector dish box 71 corresponds to the position of the placement groove 6 and the size matches. The lower part of the detector dish box 71 is movably placed in the placement groove 6.
[0032] The above scheme involves pouring the filtered agricultural product liquid sample into the detector dish 71 during testing, followed by inserting the top cover 74. This prevents external impurities from interfering with the testing environment. The electrochemical sensor 72 and optical sensor 73, fixed to the lower part of the inner wall of the detector dish 71, play a crucial role. The electrochemical sensor 72 detects pesticide residues by generating an electrical signal through a reaction with the pesticide residue components in the sample, based on electrochemical principles. The optical sensor 73 detects residues by utilizing changes in optical properties. The two sensors work together to detect pesticide residues from different angles, improving accuracy. The detector dish 71 corresponds to and matches the size of the placement slot 6, ensuring stability during testing and guaranteeing full and stable contact between the sensor and the sample, which is beneficial for accurate detection of pesticide residues.
[0033] It should be noted that this utility model is a pesticide residue detection device for organic agricultural products. During use, the operator first lifts the entire device by holding the handle opening 3 on the baffle 2 for easy transport to the testing site. Upon arrival, the organic agricultural product to be tested is placed in the agricultural product crushing box 43. The servo motor 451 in the crushing assembly 45 is then activated. The output of the servo motor 451 drives the fixed rod 452 to rotate. The fixed rod 452 rotates flexibly within the agricultural product crushing box 43 with the aid of bearings, causing the three crushing blades 454, which are arranged in a ring array on the circular block 453, to rotate at high speed, crushing the agricultural product. The crushed material moves to the right under gravity to the filter nozzle 46, where it is filtered through the fine filter holes 47 to remove larger particles and obtain a relatively fine and uniform original liquid. Then, the filtered liquid... The stock solution is carefully poured into the detector dish 71, and the top cover 74 is inserted to prevent external impurities from interfering with the detection. At this time, the electrochemical sensor 72 and the optical sensor 73 located on the lower inner wall of the detector dish 71 start to work. The electrochemical sensor 72 is based on the principle of electrochemistry. When the pesticide residue in the stock solution reacts chemically with the electrode of the sensor, it will generate a change in electrical signal. This signal is transmitted to the signal processing system in the device. The optical sensor 73 uses the changes in the optical properties of pesticide residues, such as absorption, scattering or fluorescence emission of specific light, to detect the pesticide residues, generate corresponding changes in optical signal and transmit them. After these signals are processed, the relevant detection results of pesticide residues are finally displayed on the display screen 8. The operator can also control the detection process and query data through the keypad 9, thereby realizing portable and rapid detection of pesticide residues in organic agricultural products.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
