Description

Technical Field

[0001] The present invention relates to the technical field of fruit and vegetable detection equipment, and particularly to a rapid evaluation device for the odor quality of fruits and vegetables. Background Art

[0002] With the rapid development of agricultural production and the food industry, the rapid detection of the flavor quality of fruits and vegetables has gradually become a key link in the production, processing, and sales of fruits and vegetables. Traditional methods for detecting the flavor quality of fruits and vegetables mainly rely on manual experience or simple physical measurement equipment. These methods are not only inefficient but also have large subjectivity and errors, making it difficult to meet the urgent needs of the modern standardized fruit and vegetable industry for efficient, accurate, and intelligent automated detection.

[0003] Existing fruit and vegetable odor quality detection equipment often has the following deficiencies: low detection efficiency, requiring pre-treatment of crushing / non-crushing extraction of volatile odor substances, and then desorbing them into the gas detection chamber. During this period, due to the long operation time and complex process, the reproducibility and stability of the same sample are poor, and the pre-treatment processes required for different fruit and vegetable samples vary significantly, making it difficult to homogenize and unable to meet the requirements of industrial-scale production; the detection results cannot quantitatively predict the aroma quality of fruit and vegetable samples. Due to the lack of a corresponding transfer and extraction integrated platform, it is difficult to obtain physical and chemical information such as mass and volume; complex operation, the equipment design is usually more cumbersome, requiring frequent manual adjustment of the height, angle, or light source position of the equipment, increasing the operation difficulty and reducing work efficiency; insufficient adaptability, especially when detecting large or irregular fruits and vegetables, it is easy to have problems such as unstable support or inaccurate detection data; in addition, existing equipment generally lacks flexibility and cannot adjust the distance between the detection mechanism and the fruits and vegetables, making it difficult to adapt to fruits and vegetables of different sizes and detection requirements, further limiting the application range of the equipment.

[0004] For example, in the Chinese invention patent with the application number 202311504098.X, a fruit cup and a detection system suitable for fruit and vegetable detection are disclosed. The fruit cup includes: a lining body for carrying the fruit and vegetable to be tested; a base for supporting the lining body; the base has a seat hole arranged around a central axis, and the seat hole axially penetrates the base; the lining body is fixedly connected to the base, and the lining body forms an inner hole that axially penetrates; the lining body includes: a plurality of support parts arranged at different circumferential positions to support the fruit and vegetable to be tested; a plurality of limiting parts arranged at different circumferential positions to apply a force to the fruit and vegetable to be tested after elastic contact with the fruit and vegetable to be tested; the limiting parts correspond to the support parts one by one, and a detection channel is formed between adjacent limiting parts, and the limiting parts are made of flexible materials. However, the above-mentioned rapid evaluation device for the odor quality of fruits and vegetables in the patent also has the following defects; (1)The existing fruit cups are mainly designed for fruits and vegetables with fixed shapes and sizes. Although a certain adaptability is provided through the flexible limiting part and the supporting part, the adaptability to fruits and vegetables with large size changes or irregular shapes is still limited. Especially when detecting large fruits and vegetables, the situation of unstable support is likely to occur.

[0005] (2)The multi-point limiting design of the fruit cup only realizes partial support and fixation of the fruits and vegetables. During the detection process, the ability to adjust the posture of the fruits and vegetables is insufficient, it is difficult to achieve uniform coverage of the surface of the fruits and vegetables with light, and detection dead angles are likely to appear, affecting the comprehensiveness and accuracy of the detection.

[0006] (3)The distance between the detection mechanism of the existing fruit cup and the fruits and vegetables cannot be flexibly adjusted. Especially when facing fruits and vegetables with different sizes and detection requirements, the fixed structure of the device limits the optimization and adjustment of its detection parameters, reducing the versatility and operation efficiency of the device.

[0007] A rapid evaluation device for the odor quality of fruits and vegetables specially proposed by the present invention specifically solves the above problems. Through the coordinated design of the height control mechanism, the angle control mechanism and the fruit and vegetable placement mechanism, the all-round adjustment of the height and angle of the fruits and vegetables is realized, adapting to fruits and vegetables of different sizes and shapes, and performing multi-angle odor quality detection on the surface of the fruits and vegetables during rotation and rising. Therefore, the present invention can significantly improve the efficiency and accuracy of the detection of the flavor quality of fruits and vegetables, ensure the uniform collection of the surface odor of fruits and vegetables, reduce the detection error, and improve the reliability of the flavor evaluation. Summary of the Invention

[0008] The present invention proposes a rapid evaluation device for the odor quality of fruits and vegetables specially to solve the problems of low detection efficiency, uneven odor distribution, cumbersome operation, etc. in the above-mentioned existing technologies.

[0009] To achieve the above object, the technical idea of the present invention is: (1) A height control mechanism and an angle control mechanism that are linked and coordinated are provided. The overall height of the fruits and vegetables is adjusted through the height control mechanism to meet the detection requirements of fruits and vegetables of different sizes. At the same time, under the action of the height control mechanism, the angle control mechanism rotates the fruits and vegetables, causing the fruits and vegetables to rotate while being lifted, disrupting the calm air flow inside the fruit and vegetable placement machine, enabling the rapid volatilization of the odor of the fruits and vegetables, facilitating the rapid detection by the detection box, and improving the detection efficiency. At the same time, through the cooperation of the angle control mechanism and the height control structure, the uniformity of the odor diffusion of the fruits and vegetables is achieved (rotation makes the odor emission of the fruits and vegetables change from a single direction to a chaotic state, thereby accelerating the speed of atmosphere emission and facilitating the rapid detection of the fragrance by the detection box), ensuring that the surface of the fruits and vegetables is evenly exposed in the detection area, facilitating comprehensive odor detection.

[0010] (2) A fruit and vegetable detection mechanism is provided. The fruit and vegetable detection mechanism includes a telescopic bearing assembly and a protective member. The protective member rotates synchronously with the angle control mechanism, and the protective member stably supports and protects the fruits and vegetables through elastic materials and buffer designs, effectively preventing damage to the fruits and vegetables caused by detection movements, and at the same time providing flexible detection capabilities suitable for fruits and vegetables of various shapes and sizes.

[0011] (3) A light rotation mechanism is provided. Through the light rotation mechanism, omnidirectional light source illumination is provided. The lamp tube rotates around the fruits and vegetables, achieving uniform and multi-angle light coverage, ensuring the accuracy and integrity of the flavor quality detection data, avoiding detection dead corners at the same time, and facilitating the user to observe the detection environment.

[0012] To achieve the above object, the technical solution adopted by the present invention is: A rapid evaluation device for the odor quality of fruits and vegetables dedicated, including a fruit and vegetable placement machine and a detection box provided on the upper part of the fruit and vegetable placement machine. A fruit and vegetable placement mechanism is provided inside the fruit and vegetable placement machine, and a height control mechanism is provided below the fruit and vegetable placement mechanism; an angle control mechanism is provided between the height control mechanism and the fruit and vegetable placement mechanism, and the bottom of the fruit and vegetable placement mechanism is connected to the bottom of the height control mechanism through the angle control mechanism.

[0013] Further, the angle control mechanism includes a support member. The support member is provided at the bottom of the fruit and vegetable placement mechanism, and the support member is movably connected to the bottom of the height control mechanism through a rotating arm.

[0014] Further, the rotating arm includes a connecting member. One end of the connecting member is hinged to the bottom of the height control mechanism, and the other end is connected to the support member through an elastic member.

[0015] Further, the support member includes a base and a hydraulic support rod. The base is sleeved on the bottom of the fruit and vegetable placement mechanism, the side wall of the base is connected to the end of the elastic member, and the hydraulic support rod is provided on the top of the base.

[0016] With the above technical solutions, further, the fruit and vegetable placement mechanism includes a telescopic load-bearing rod that penetrates through the base and is sleeved with a protective member on the rod body. A buffer member is provided at the top of the telescopic load-bearing rod, and the edge of the buffer member is connected to the inner top wall of the protective member; a plurality of hydraulic support rods are arranged around the telescopic load-bearing rod, and the tops of the plurality of hydraulic support rods are all connected to the bottom of the protective member.

[0017] Furthermore, the telescopic load-bearing rod includes an adjustment support rod and an elastic bearing member. The adjustment support rod is located on the base, the elastic bearing member is sleeved on the top of the adjustment support rod, and a spring is provided inside the elastic bearing member. The spring is located between the inner top wall of the elastic bearing member and the top of the adjustment support rod.

[0018] Further, the buffer member includes a first connecting rod, an elastic adjustment element, and a second connecting rod. One end of the first connecting rod is connected to the inner wall of the protective member, and the other end is connected to one end of the second connecting rod through the elastic adjustment element. The other end of the second connecting rod is connected to the elastic bearing member.

[0019] Further, a plurality of second connecting rods are circumferentially and uniformly arranged on the elastic bearing member.

[0020] Furthermore, the height control mechanism includes a bolt adjustment member and a lifting mechanism. The bolt adjustment member is arranged in the sliding groove at the bottom of the fruit and vegetable placement machine, and the bolt adjustment member is threadedly connected to the lifting mechanism.

[0021] Further, the lifting mechanism includes a first lifting frame and a second lifting frame. The centers of the side walls of the first lifting frame and the second lifting frame are hinged. The bolt adjustment member is threadedly connected to the bottom wall of the first lifting frame; The connecting member is hinged to the end of the bottom wall of the first lifting frame or the bottom end of the second lifting frame.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a linked height control mechanism and an angle control mechanism, the detection height and angle of fruits and vegetables can be adjusted quickly and flexibly to adapt to fruits and vegetables of different sizes and shapes. During the lifting process of fruits and vegetables, the change in angle can promote the flow of the surrounding air and cause rotation, which helps to spread the odor. This rotation makes the surface odor of fruits and vegetables more evenly distributed in the detection area, improving the detection effect of the odor sensor and ensuring the accuracy and integrity of the detection data.

[0023] 2. The fruit and vegetable detection mechanism adopts a telescopic load-bearing component and a protective member design, which can adapt to fruits and vegetables of different shapes and sizes and provide buffer protection during the detection movement to prevent fruits and vegetables from being damaged due to pressure or vibration. The overall structure design is compact and the operation is convenient, improving the versatility and safety of the equipment. At the same time, the fruit and vegetable detection mechanism ensures the stable support of fruits and vegetables through buffer and elastic designs, improving the accuracy and reliability of the detection process.

[0024] 3. Through the design of the light rotation mechanism, the present invention provides an all-round light source irradiation to ensure that fruits and vegetables can be evenly irradiated at all angles during the detection process. This optimizes the lighting environment for flavor quality detection, enables users to intuitively observe the detection status, and ensures the smooth progress of the entire detection process. This design greatly improves the operation convenience and detection efficiency of the device, meeting the needs of large-scale detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0028] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0030] Embodiment 1 Combined with Figures 1 to 14 , the present invention discloses a special odor quality rapid evaluation device for fruits and vegetables, including a fruit and vegetable placement machine 1 and a detection box 2 arranged on the upper part of the fruit and vegetable placement machine 1. A fruit and vegetable placement mechanism 5 is arranged inside the fruit and vegetable placement machine 1, and a height control mechanism 3 is arranged below the fruit and vegetable placement mechanism 5; An angle control mechanism 4 is arranged between the height control mechanism 3 and the fruit and vegetable placement mechanism 5, and the bottom of the fruit and vegetable placement mechanism 5 is connected to the bottom of the height control mechanism 3 through the angle control mechanism 4.

[0031] As Figure 1The fruit and vegetable placement machine 1 includes a body 11, a placement plate 12, and wheels 13. A detection box 2 is arranged on the top of the body 11, the placement plate 12 is slidably connected inside the body 11, and four wheels 13 are fixed at the four corners of the bottom of the body 11 through bearings or other connection methods. The wheels 13 provide mobility for the device and facilitate the movement of the device between different locations.

[0032] Specifically, the body 11 is the main structure of the fruit and vegetable placement machine 1, which is in the shape of a rectangular frame. A rectangular window is set on the front side to facilitate the taking of fruits and vegetables. The window position is connected to the fruit and vegetable placement area inside the device to ensure that the user can easily access and place the fruits and vegetables to be tested.

[0033] Specifically, the detection box 2 has the ability to collect and analyze data on fruits and vegetables. The detection box 2 is equipped with at least 16 sensors and supports up to 22 sensor modules. It can detect volatile substances with high precision and has excellent sensitivity (such as the detection limit of ethanol is 15ppb). The sensor works stably at high temperatures (200-500℃) and has automatic detection and diagnosis functions. The detection box 2 is also equipped with an efficient sampling system and adjustable flow control to ensure long-term stable operation. The data acquisition and analysis software supports powerful data processing capabilities, including a variety of analysis methods, such as neural networks, principal component analysis (PCA), support vector machines (SVM), etc., which are suitable for the analysis of gas, liquid and solid samples. In use, the detection box 2 collects the odors of fruits and vegetables to achieve a comprehensive analysis of fruits and vegetables.

[0034] like Figure 4 Two rectangular slide grooves 111 are relatively arranged at the bottom of the fuselage 11, and a height control mechanism 3 is slidably connected to the slide groove 111, wherein the height control mechanism 3 includes a bolt adjustment member 31 and a lifting mechanism 32, the bolt adjustment member 31 is arranged inside the front slide groove 111, and penetrates the front slide groove 111 and is rotatably connected to the bottom of the fuselage 11, and the lifting mechanism 32 is sleeved on the bolt adjustment member 31, and the lifting mechanism 32 realizes the lifting action under the rotation of the bolt adjustment member 31; like Figure 6 The lifting mechanism 32 includes a first lifting frame and a second lifting frame. The first lifting frame includes two first adjustment blocks 321 arranged diagonally, and the two ends of the two first adjustment blocks 321 are movably connected through a hinge rod 3231. The second lifting frame has the same structure as the first lifting frame, and includes two second adjustment blocks 322 arranged diagonally, and the two ends of the two second adjustment blocks 322 are also movably connected through a hinge rod 3231. The first lifting frame and the second lifting frame are hinged at the center of the hinge rod 3231 located on the same side wall through a hinge shaft 3232.

[0035] Specifically, the first adjustment block 321 at the bottom of the first lifting frame is slidably installed in the slide groove 111 at the bottom of the fruit and vegetable placing machine 1, and is threadedly connected with the bolt adjustment rod 31. When the operator rotates the bolt adjustment member 31, the bolt adjustment member 31 is connected with the first adjustment block 321, so that the first adjustment block 321 moves smoothly along the longitudinal direction in the slide groove 111. The movement of the first adjustment block 321 drives the first lifting frame and the second lifting frame to move simultaneously, and the lifting mechanism 32 as a whole rises or falls accordingly.

[0036] Embodiment 2 refer to Figures 1 - 14 Different from the above-mentioned embodiment 1, an angle control mechanism 4 is also provided. The angle control mechanism 4 includes a rotating arm 41 and a support member 42. The support member 42 is arranged at the bottom of the fruit and vegetable placement mechanism 5, and the support member 42 is movably connected to the bottom of the height control mechanism 3 through the rotating arm 41.

[0037] like Figure 7 One end of the two rotating arms 41 rotates and is relatively connected to the diagonal line of the inner wall of the lifting mechanism 32, and the other end is connected to the support member 42. Specifically, a rotation adjustment shaft 3211 is provided at the end of the first adjustment block 321 located at the bottom of the first lifting frame. Similarly, a rotation adjustment shaft 3211 is also provided at the end of the second adjustment block 322 located at the bottom of the second lifting frame. These two rotation adjustment shafts 3211 can be distributed on the diagonal line or symmetrically distributed. The rotation adjustment shaft 3211 is connected to the elastic member 412 through the connecting member 411, and the end of the elastic member 412 is connected to the support member 42, finally forming a stable support and adjustment system. Through this system, the angle control mechanism 4 can maintain precise angle adjustment during the entire lifting process.

[0038] like Figure 8 A hydraulic support rod 422 is arranged on the periphery of the base 421, the base 421 is sleeved on the bottom of the fruit and vegetable placement mechanism 5, the side wall of the base 421 is connected to the end of the elastic member 412, and the hydraulic support rod 422 is arranged on the top of the base 421. The hydraulic support rod 422 is used to provide additional support force to enhance the stability of the equipment. The length of the hydraulic support rod 422 can be adjusted to ensure that the equipment remains stable during the lifting process.

[0039] Specifically, when the operator rotates the bolt adjuster 31, the first adjusting block 321 provided at the bottom of the first lifting frame and the second adjusting block 322 provided at the bottom of the second lifting frame move relatively inward along the sliding groove 111 simultaneously, and at the same time drive the rotating arm 41 in the angle control mechanism 4 to rotate. Due to the connection between the rotating arm 41 and the lifting mechanism 32, the lifting of the lifting mechanism 32 and the angle adjustment of the angle control mechanism 4 are carried out synchronously, so as to ensure that the equipment can be adjusted to the required angle while the height changes. The elastic member 412 ensures the smoothness during the angle adjustment process by providing an elastic force, and avoids the generation of excessive force, protecting other components of the equipment from damage.

[0040] It is worth noting that when the fruits and vegetables rise while twisting, it can effectively mobilize the flow of the surrounding air, which helps the flow and diffusion of the smell. This enables the smell released from the surface of the fruits and vegetables to quickly spread into the air, increasing the capture and detection range of the smell sensor for the smell. In addition, as the fruits and vegetables rotate, the smell is evenly distributed on the surface of the fruits and vegetables, which not only ensures the rapid diffusion of the smell, but also enables the smell sensor to collect the smell information released by the fruits and vegetables more comprehensively and accurately at different angles.

[0041] Embodiment III Reference Figures 1 - 14 , different from the above Embodiment I, there is also provided a fruit and vegetable placement mechanism 5. The fruit and vegetable placement mechanism 5 includes a telescopic load-bearing rod 51, a protection member 52 and a buffer member 53. The telescopic load-bearing rod 51 is connected to the bottom of the fuselage 11. The support member 42 and the lower part of the telescopic load-bearing rod 51 are fixedly connected by means of high-strength industrial glue or the like. A protection member 52 is sleeved on the telescopic load-bearing rod 51, and the end of the telescopic load-bearing rod 51 is connected to the inner wall of the protection member 52 through the buffer member 53.

[0042] Such as Figure 9 , the telescopic load-bearing rod 51 is distributed through the base 421, and a protection member 52 is sleeved on the rod body, and a buffer member 53 is provided at the top of the telescopic load-bearing rod 51, and the edge of the buffer member 53 is connected to the inner top wall of the protection member 52; A plurality of hydraulic support rods 422 are arranged around the telescopic load-bearing rod 51, and the tops of the plurality of hydraulic support rods 422 are all connected to the bottom of the protection member 52. By adjusting its length, stable support is provided to ensure that the fruits and vegetables will not move or tilt during the detection process. The design of the telescopic load-bearing rod 51 allows it to be adjusted within different height ranges to adapt to the placement requirements of fruits and vegetables of different sizes and shapes.

[0043] The telescopic load-bearing rod 51 includes an adjustable support rod 511 and an elastic bearing member 512. The adjustable support rod 511 is located on the base 421, and the elastic bearing member 512 is sleeved on the top of the adjustable support rod 511. A spring 513 is provided inside the elastic bearing member 512, and the spring 513 is located between the inner top wall of the elastic bearing member 512 and the top of the adjustable support rod 511.

[0044] Specifically, the adjustable support rod 511 is fixedly connected to the bottom of the fuselage 11, and a support member 42 is rotatably sleeved on the outer side of its lower part. Under the action of the lifting mechanism 32, the support member 42 will rotate with the movement of the lifting mechanism 32, and the telescopic load-bearing rod 51 will adjust its length according to the height of the lifting mechanism 32 rising, so as to realize the height adjustment of the fruit and vegetable placement.

[0045] Specifically, the elastic bearing member 512 is sleeved on the end of the adjustable support rod and is used to directly bear the fruits and vegetables to be detected. The elastic bearing member 512 can be installed on the adjustable support rod by sliding or other appropriate means to ensure that the fruits and vegetables can be stably placed.

[0046] It should be noted that the spring 513 is arranged inside the elastic bearing member 512 and is used to provide elastic support and buffering. The main function of the spring 513 is to relieve the vibration or impact that may occur during the detection of fruits and vegetables, and ensure that the fruits and vegetables will not be subjected to excessive pressure or damage during the lifting process. By adjusting its elasticity, the spring 513 can control the resistance of the elastic bearing member 512 when moving up and down, ensuring that the fruits and vegetables always remain in a stable state.

[0047] Specifically, when the lifting mechanism 32 rises, the adjustable support rod 511 drives the elastic bearing member 512 to move together, and through the buffering of the spring 513, it ensures that the fruits and vegetables move smoothly, avoiding damage to the fruits and vegetables caused by vibration or sudden stop. The spring 513 provides an elastic restoring force, enabling the elastic bearing member 512 to maintain stability during the lifting process and ensuring that the fruits and vegetables are always properly supported.

[0048] Specifically, the protection member 52 is installed on the upper part of the telescopic load-bearing rod 51, and its main function is to provide support for the edges of large fruits and vegetables. The middle part of the protection member 52 is clamped on the placement plate 12 of the fruit and vegetable placement machine 1. Through the connection with the telescopic load-bearing rod 51, the protection member 52 is allowed to move with the telescopic load-bearing rod 51 when the lifting mechanism 32 rises, so as to always maintain stable support for the fruits and vegetables and ensure that the fruits and vegetables can be stably fixed in the placement area.

[0049] Specifically, the buffer member 53 is located at the end of the telescopic load-bearing rod 51 and is connected to the inner wall of the protection member 52 through the telescopic load-bearing rod 51. The main function of the buffer member 53 is to slow down the impact between the fruits and vegetables and the protection member 52, preventing the fruits and vegetables from being affected by vibration or external force. The buffer member 53 effectively absorbs the impact force during the lifting process, enabling the fruits and vegetables to smoothly enter the detection area and ensuring the accuracy of the detection data.

[0050] Specifically, three buffer members 53 are evenly arranged along the circumferential direction of the elastic load-bearing member 512 to ensure uniform distribution of the force in different directions. Both ends of the buffer member 53 are respectively hinged to the inner wall of the protection member 52 and the side of the elastic load-bearing member 512. The hinged structure allows the buffer member 53 to move flexibly during use and can change its position as the protection member 52 rotates.

[0051] Specifically, when the protection member 52 rotates, the buffer member 53 also rotates around the elastic load-bearing member 512 together with the protection member 52. Since the elastic load-bearing member 512 is made of a plastic material such as rubber, when the fruits and vegetables are placed on the elastic load-bearing member 512, a slight downward deformation will occur, causing the spring of the buffer member 53 to be slightly compressed, making the movement of the buffer member 53 smooth and adjustable, and ensuring that there will be no excessive friction or unnecessary vibration during the operation.

[0052] As Figure 10 , the buffer member 53 includes a first connecting rod 531, an elastic adjusting element 532, and a second connecting rod 533. The first connecting rod 531 is connected to the hinged connecting rod provided on the inner wall of the protection member 52. The first connecting rod 531 is connected to the second connecting rod 533 through the elastic adjusting element 532. The second connecting rod 533 is rotatably connected to the elastic load-bearing member 512.

[0053] As Figure 12 , the second connecting rod 533 includes a linkage joint 5331, a rotating connecting rod 5332, and a sliding limiting member 5333. The linkage joint 5331 is connected to the end of the elastic adjusting element 532. The rotating connecting rod 5332 is rotatably connected to the linkage joint 5331. The sliding limiting member 5333 is provided at the end of the second connecting rod 533, and its function is to limit the sliding range of the second connecting rod 533, prevent excessive displacement during the lifting process, ensure the stability of the device during height adjustment, and avoid damage to the fruits and vegetables caused by excessive displacement.

[0054] Embodiment Four Reference Figures 1 - 14 , different from the above Embodiment One, a lighting rotation mechanism 6 is further provided. The lighting rotation mechanism 6 is arranged on the upper part of the fuselage 11 and includes a trigger wheel 61, a driving rod 62, and a lamp tube 63. Two driving rods 62 are connected to the trigger wheel 61 in opposite directions, and the end of the driving rod 62 is engaged with the end of the lamp tube 63.

[0055] As Figure 14 , the trigger wheel 61 is one of the core components of the lighting rotation mechanism 6, which is set at the top of the mechanism and located in the middle position of the lamp tube 63. The trigger wheel 61 is usually circular and has a gear structure, which can mesh with the gear part of the driving rod 62. The trigger wheel 61 drives the driving rod 62 through rotation, so as to realize the rotation of the lamp tube 63.

[0056] Specifically, the driving rods 62 are located on both sides of the trigger wheel 61 and are symmetrically arranged. One end of each driving rod 62 is connected to the trigger wheel 61, and the other end is meshed with the lamp tube 63. The driving rod 62 is in an elongated shape, usually rectangular or cylindrical, and has a gear structure matching the gear of the trigger wheel 61. By driving the rotation of the trigger wheel 61, the driving rod 62 moves in the horizontal direction and drives the lamp tube 63 to rotate.

[0057] Specifically, the lamp tube 63 is located at the end of the driving rod 62 and is connected by meshing. The lamp tube 63 is usually in a long strip shape or cylindrical shape, and is connected to the driving rod 62 through a corresponding meshing structure (such as a gear or a cam). The lamp tube 63 generates light through rotation for irradiating the fruit and vegetable detection area. Driven by the driving rod 62, the lamp tube 63 rotates around its central axis to achieve uniform light coverage.

[0058] Specifically, the lamp tube 63 includes a lamp holder 631, a driving wheel 632 and a lamp body 633. The lamp holder 631 is rotatably connected to the fuselage 11 to provide support and rotation functions; the driving wheel 632 is fixed at the end of the lamp holder 631, and realizes the rotation drive of the lamp tube 63 by meshing with the driving rod 62; the lamp body 633 is installed between the lamp holders 631 and is connected to the lamp holder 631 through a fixing structure. The driving rod 62 drives the driving wheel 632 to rotate, so that the lamp body 633 rotates smoothly around the central axis to complete the uniform illumination of the fruit and vegetable detection area.

[0059] Embodiment Five Different from the above embodiments, a special fruit and vegetable odor quality rapid evaluation device detects fruits and vegetables, including the following steps: After the device is started, the lighting rotation mechanism 6 starts to work. The trigger wheel 61 drives the driving rod 62, thereby driving the lamp tube 63 to rotate around the fruit and vegetable to achieve uniform illumination. The light source covers all angles of the fruit and vegetable, which helps the detector to observe the detection environment.

[0060] The operator places the fruit and vegetable to be detected on the elastic bearing member 512 of the fruit and vegetable placement machine 1 to ensure that the fruit and vegetable is firmly in the detection position. For larger fruits and vegetables, their edges will overlap on the edges of the protection member 52 to form additional support.

[0061] The operator adjusts the adjusting bolt 31 to make the lifting mechanism 32 drive the fruit and vegetable placement machine 1 to adjust to a suitable detection height. At the same time, the lifting mechanism 32 drives the angle control mechanism 4 to rotate, so that the fruits and vegetables rotate while being lifted.

[0062] During the detection process, the fruits and vegetables are mainly supported by the elastic bearing member 512. For larger fruits and vegetables, their edges will overlap the edges of the protection member 52 and rotate together with the protection member 52 to avoid shaking or damage to the fruits and vegetables caused by the detection movement.

[0063] The device moves synchronously with the rotating light source and the fruits and vegetables to scan the fruits and vegetables from multiple angles and collect relevant data on their flavor and quality. During the process, the buffer member 53 and the spring 513 absorb the vibrations during the movement, ensuring the stability of the fruits and vegetables and improving the accuracy of the detection.

[0064] After the detection is completed, the fruits and vegetables return to the initial position stably. The operator safely takes out the fruits and vegetables, and the device resumes the standby state to prepare for the next round of detection.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention; therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
