For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0030] like Figures 1 to 7As shown, this utility model provides an agricultural product safety testing instrument, including a base 1, a drive assembly 2, a rotating disk 3, at least two receiving cups 4, and a testing instrument body 5. The base 1 serves as the supporting structure for the entire testing instrument, supporting other components. The drive assembly 2 is fixedly mounted on the base 1 and provides power. The rotating disk 3 is connected to the drive assembly 2 and can rotate around its central axis under the drive of the drive assembly 2. The testing instrument body 5 is also connected to the drive assembly 2 and can move vertically up and down under the drive of the drive assembly 2. The at least two receiving cups 4 are fixedly mounted on the upper surface of the rotating disk 3, used to hold the sample to be tested, and the receiving cups 4 move to different positions as the rotating disk 3 rotates.

[0031] The working principle of the agricultural product safety testing instrument is as follows: In use, the target detection part of the agricultural product is first removed, crushed, and mixed with an organic solvent to form a test mixture. Then, the test mixture is poured into the receiving cups 4. The driving component 2 is activated, driving the rotating disk 3 to rotate, moving one of the receiving cups 4 directly below the instrument body 5. Simultaneously, the driving component 2 drives the instrument body 5 downwards, extending it into the receiving cup 4 to detect pesticide residues in the test mixture. After detection, the driving component 2 drives the instrument body 5 upwards, removing it from the receiving cup 4. Subsequently, the rotating disk 3 continues to rotate, moving the next receiving cup 4 below the instrument body 5, repeating the above testing process to achieve continuous testing of multiple samples.

[0032] The detector body 5 includes a main body 51 and a detection probe 52. The main body 51 is the main structure of the detector body 5, connected to the drive assembly 2, and is used to carry the detection probe 52 and provide power and signal processing functions. The detection probe 52 is located at the lower end of the main body 51 and can extend into the receiving cup 4 under the drive of the drive assembly 2 to directly contact the mixture to be tested, thereby realizing the detection of pesticide residues.

[0033] The working principle of the detector body 5 is based on spectral analysis technology, specifically as follows: The body 51 has a built-in light source module, signal processor, and data transmission unit. The detection probe 52 includes an optical window, a light receiver, and a light path guiding structure. The optical window is used to contact the mixture to be tested. The light source module emits a light beam of a specific wavelength (e.g., ultraviolet or near-infrared light), which is transmitted to the optical window through the light path guiding structure. After the light beam penetrates or is absorbed by pesticide or veterinary drug residue molecules in the mixture to be tested, part of the light is reflected or scattered and returns to the light receiver. The light receiver converts the received light signal into an electrical signal and transmits it to the signal processor inside the body 51. The signal processor analyzes the spectral characteristics (such as the position and intensity of absorption peaks) and compares them with a pre-stored standard spectral database to identify the type and concentration of pesticides or veterinary drugs in the mixture to be tested, and finally outputs the detection result through the data transmission unit.

[0034] To meet the testing needs of different types of agricultural products, the light source wavelength of the detection probe 52 is adjustable, for example, detecting organophosphorus pesticides in the 200-400 nm range, or pyrethroid pesticides in the 600-1000 nm range. Furthermore, the outer surface of the detection probe 52 is made of corrosion-resistant materials (such as stainless steel or Teflon coating) to prevent corrosion by organic solvents and facilitate cleaning, thereby ensuring the stability and accuracy of multiple tests.

[0035] Compared with existing technologies, this invention, by setting up multiple receiving cups 4 and coordinating with the rotation function of the rotating disk 3, can achieve continuous detection of multiple samples, avoiding the limitation of traditional detection devices that can only detect one sample at a time. The driving component 2 simultaneously controls the movement of the rotating disk 3 and the detector body 5, resulting in a compact structure, simple operation, and significantly improved detection efficiency. It is particularly suitable for the safety detection needs of large-scale agricultural products.

[0036] In this embodiment, the drive assembly 2 of the agricultural product safety testing instrument includes a first rotating shaft 21, a driven bevel gear 22, a driving bevel gear 23, a power source assembly 24, a drive shaft 25, a drive arm 26, a driven arm 27, and a sliding shaft 28. The first rotating shaft 21 is rotatably mounted on the upper surface of the base 1 via bearings, and its axis is arranged vertically. The driven bevel gear 22 is fixedly sleeved on the lower part of the first rotating shaft 21 and rotates coaxially with the first rotating shaft 21. The drive shaft 25 is horizontally arranged, with one end connected to the output end of the power source assembly 24 and the other end fixedly connected to the driving bevel gear 23. The driving bevel gear 23 meshes with the driven bevel gear 22 to form a right-angle transmission structure, so as to convert the horizontal rotation of the drive shaft 25 into the vertical rotation of the first rotating shaft 21. The drive arm 26 is fixedly connected to one end of the drive shaft 25 near the drive bevel gear 23. The end of the drive arm 26 away from the drive shaft 25 is connected to one end of the driven arm 27 by a hinge, and the other end of the driven arm 27 is connected to the sliding shaft 28 by a hinge.

[0037] The rotating disk 3 is fixedly installed on the upper end of the first rotating shaft 21 and rotates synchronously with the first rotating shaft 21. A slide rail 11 is provided on the upper surface of the base 1. The slide rail 11 has an I-shaped cross-section and includes a connecting portion 111 in the middle and guide portions on both sides. A strip-shaped notch 112 is formed in the vertical direction of the connecting portion 111. A slider 12 is slidably installed on the slide rail 11. The bottom of the slider 12 slides in cooperation with the guide portions of the slide rail 11, and the top is fixedly connected to the detector body 5. One end of the sliding shaft 28 is fixed to the slider 12, and the other end passes through the strip-shaped notch 112 and connects to the driven arm 27, thereby allowing the slider 12 to slide back and forth in the vertical direction within the slide rail 11.

[0038] The working principle of the drive assembly 2 is as follows: The power source assembly 24 (e.g., a motor) is activated, driving the drive shaft 25 to rotate around its own axis. The rotation of the drive shaft 25, on the one hand, drives the first rotating shaft 21 to rotate through the meshing of the driving bevel gear 23 and the driven bevel gear 22, thereby causing the rotating disk 3 to rotate synchronously with the first rotating shaft 21, realizing the position switching of the receiving cup 4; on the other hand, the rotation of the drive shaft 25 simultaneously drives the drive arm 26 to perform circular motion around the axis of the drive shaft 25. The drive arm 26, through a hinge, drives the driven arm 27 to move, and the driven arm 27 converts the rotational motion into the vertical reciprocating motion of the sliding shaft 28 within the strip-shaped notch 112. The sliding shaft 28 then drives the slider 12 to slide up and down along the slide rail 11, enabling the detector body 5 to complete the actions of extending into and removing from the receiving cup 4.

[0039] Furthermore, in this embodiment, the number of receiving cups 4 is six, and the six receiving cups 4 are distributed in a ring at equal intervals on the upper surface of the rotating disk 3. The rotation speed of the power source assembly 24 and the length of the drive arm 26 are precisely designed so that the rotating disk 3 rotates 60 degrees each time (i.e., the angle between two adjacent receiving cups 4), precisely moving one receiving cup 4 directly below the detector body 5; at the same time, the linkage of the drive arm 26 and the driven arm 27 causes the detector body 5 to descend precisely into the receiving cup 4, completing the detection action. After the detection is completed, the detector body 5 rises and moves out of the receiving cup 4 with the slider 12, and the rotating disk 3 continues to rotate to the position of the next receiving cup 4, thus repeating the cycle to achieve continuous detection of multiple samples.

[0040] Compared with existing technologies, this embodiment, through the bevel gear transmission and linkage mechanism design of the drive component 2, utilizes a single power source component 24 to simultaneously realize the rotation of the rotating disk 3 and the lifting and lowering movement of the detector body 5. This results in a compact structure and high reliability of mechanical linkage. The circular arrangement of the six containing cups 4 further improves detection efficiency, making it suitable for rapid and safe detection of large quantities of agricultural products.

[0041] The following is a detailed description of the modified implementation of the power source component 24 and housing 6 provided by you. The modified version is more detailed, logically clear, concisely written, and complies with the requirements of patent law for technical solutions. It highlights the structural function and protective role, while maintaining consistency with the previous design of the drive component 2 and the overall testing instrument. The following is the modified content:

[0042] In this embodiment, the power source assembly 24 includes a first motor 241, a worm gear 242, and a worm wheel 243. The first motor 241 is fixedly mounted on the base 1, providing rotational driving force as a power source. Its output end is fixedly connected to one end of the worm gear 242 via a coupling. The worm gear 242 is arranged horizontally and meshes with the worm wheel 243 to form a worm gear transmission mechanism. The worm wheel 243 is fixedly sleeved on the drive shaft 25 and rotates coaxially with the drive shaft 25. The working principle of the power source assembly 24 is as follows: When the first motor 241 is started, the output end of the first motor 241 drives the worm gear 242 to rotate around its axis. The rotation of the worm gear 242 drives the worm wheel 243 to rotate through meshing. The worm wheel 243 then drives the drive shaft 25 to rotate around its own axis, thereby transmitting power to other components of the drive assembly 2, realizing the rotation of the rotating disk 3 and the lifting and lowering movement of the detector body 5.

[0043] Furthermore, the transmission design of the worm gear 243 and the worm 242 has a self-locking characteristic. That is, when the first motor 241 stops operating, the worm 242 can restrict the reverse rotation of the worm gear 243, thereby preventing the drive shaft 25 from rotating unexpectedly in a non-working state and ensuring the stability of the position during the detection process. In addition, the first motor 241 can be a stepper motor or a servo motor to achieve synchronization of the movement of the rotating disk 3 and the detector body 5 by precisely controlling the speed and angle.

[0044] In this embodiment, the agricultural product safety testing instrument further includes a housing 6. The housing 6 is fixedly installed on the upper surface of the base 1 and has a cover-like structure, fitting over the drive assembly 2, and enclosing the first rotating shaft 21, driven bevel gear 22, driving bevel gear 23, power source assembly 24, and drive shaft 25 within it. The housing 6 is made of metal or high-strength plastic and has dustproof, moisture-proof, and impact-resistant properties, protecting the internal components of the drive assembly 2 from external environmental influences, while reducing noise during operation and ensuring the stability and safety of the equipment in complex environments.

[0045] The agricultural product safety testing instrument also includes a support frame 7, which comprises a support column 71, a first support arm 72, and a second support arm 73. The bottom end of the support column 71 is fixedly connected to the upper surface of the base 1 and extends vertically to provide height support. The first support arm 72 is connected to the upper end of the support column 71, allowing the first support arm 72 to rotate horizontally around the axis of the support column 71. The second support arm 73 is rotatably connected to the first support arm 72 via a connector 74 (described later), with its rotation axis set horizontally. A bolt 75 is also threaded onto the upper part of the support column 71. The nut of the bolt 75 can be tightened to make close contact with the upper surface of the first support arm 72, using the friction between the nut and the first support arm 72 to fix the position of the first support arm 72 relative to the support column 71, thereby restricting its free rotation.

[0046] The support frame 7 also includes a connector 74, which has an I-shaped cross-section. One end of the connector 74 is fixedly connected to the end of the first support arm 72, and the other end is rotatably connected to the second support arm 73 via a pivot. The connector 74 has multiple mounting slots 741 distributed along its length. A spring 742 is fixedly installed in each mounting slot 741, and a steel ball 743 is connected to the free end of the spring 742. The lower surface of the second support arm 73 has multiple grooves 731 that match the positions of the steel balls 743. Under normal conditions, the elastic force of the spring 742 causes a portion of the steel ball 743 to protrude from the mounting slot 741 and embed into the groove 731, thereby positioning and limiting the rotation of the second support arm 73 relative to the first support arm 72. By applying external force to move the second support arm 73, the steel ball 743 can be pressed back into the mounting slot 741, allowing the second support arm 73 to switch to different angular positions and reposition itself through the groove 731.

[0047] In this embodiment, the agricultural product safety testing instrument further includes a homogenizing mechanism 8, which is mounted on the second support arm 73 and is used to prepare the mixture to be tested. The homogenizing mechanism 8 includes a homogenizing cup body 81, a cover body 82, a second motor 83, a second rotating shaft 84, a blade 85, an electrically controlled valve 86, and a discharge pipe 87. The homogenizing cup body 81 is a container with an open top, and its top is detachably fixed to the cover body 82 via a threaded connection, facilitating disassembly and cleaning. The second motor 83 is fixedly installed inside the cover body 82, and its output end is connected to the upper end of the second rotating shaft 84 via a coupling. The second rotating shaft 84 extends vertically, and its lower end is fixedly connected to the blade 85, which is located inside the homogenizing cup body 81. The electrically controlled valve 86 is installed at the bottom of the homogenizing cup body 81 and is used to control material discharge. The discharge pipe 87 communicates with the outlet of the electrically controlled valve 86, and its outlet faces downwards.

[0048] The working principle of the homogenizing mechanism 8 is as follows: The part of the agricultural product to be tested is placed in the homogenizing cup 81, and an appropriate amount of organic solvent is added. Then, the cover 82 is tightened. The second motor 83 is started, which drives the second rotating shaft 84 to rotate. The second rotating shaft 84 drives the blade 85 to rotate at high speed. The rotation of the blade 85 breaks the part of the agricultural product to be tested into fine particles on the one hand, and stirs the organic solvent in the homogenizing cup 81 on the other hand, so that the broken agricultural product and the organic solvent are fully mixed to form a uniform test mixture. After completion, the position of the homogenizing cup 81 is adjusted by moving the second support arm 73 so that the outlet of the discharge pipe 87 is aligned with the mouth of the container cup 4. Then, the electronically controlled valve 86 is opened to discharge the test mixture into the container cup 4 through the discharge pipe 87 for subsequent safe testing by the detector body 5.

[0049] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
