Description

Technical Field

[0002] Currently, non-destructive near-infrared spectroscopy is widely used to assess the internal quality of fruit during the quality assessment and sorting of agricultural products. Compared to traditional analytical techniques, near-infrared spectroscopy offers numerous advantages. It can measure multiple performance indicators of a sample simply by collecting and measuring its near-infrared spectrum within minutes. Halogen lamps are commonly used as near-infrared light sources in practical applications due to their low cost and continuous, stable spectral output.

[0003] Currently, fruit and vegetable testing uses a halogen lamp to illuminate the test object and collect the near-infrared spectrum after absorption. A spectrometer then quantitatively analyzes this spectrum to identify the wavelength characteristics of the agricultural product. Furthermore, in modern industrial-scale processing, fruit and vegetable processing plants have diverse processing types and requirements. During this testing process, agricultural products of varying sizes, shapes, and characteristics are encountered. The intensity and location of the light source vary depending on the type of product.

[0004] The inventors have found that most existing near-infrared irradiation devices are fixed, and their irradiation angle cannot be adjusted or only the distance between the light source and the signal receiving end can be adjusted forward and backward, which limits their flexibility and efficiency in practical applications.

The second arc-shaped holes 121 have an adjustable angle of 30-60°, preferably 40-45°. The adjustable angle can be understood as follows: the second center of the circle is drawn along the two end points of the second arc, and the adjustable angle is the angle between these two rays.

[0055] Of course, in other embodiments, the second adjustment plate 120 has one, three, four or five second arc-shaped holes 121 ; when there are multiple second arc-shaped holes 121 , the multiple second arc-shaped holes 121 are arranged at equal angles around the second center.

[0056] Optionally, refer to Figure 5 The second adjusting plate 120 is provided with a second limiting hole 122 having the same curvature as the second arc-shaped hole 121, and the second limiting hole 122 is set on the upper side of the second arc-shaped hole 121 and the lower side of the second arc-shaped hole 121; it can be understood that the second arc-shaped hole 121 and the second limiting holes 122 set above and below it are concentric arc holes with the second circle center as the center.

[0060] Please refer to Figure 1-Figure 5In this embodiment, the lamp group adjustment structure 010 includes a lamp group module 200 .

[0061] In this embodiment, please refer to Figure 1-Figure 5 The lamp group adjustment structure 010 is provided with two lamp group modules 200 , and the two ends of the two lamp group modules 200 are slidingly connected to the first arc hole 111 and the second arc hole 121 respectively.

[0062] In this embodiment, the lamp module 200 includes a fixing plate 210 and six light source bodies 220 disposed on the fixing plate 210. The six light source bodies 220 are arranged along the focus of the light source body 220. Of course, in other embodiments, the number of light source bodies 220 may be one, two, or three.

[0063] Please refer to Figure 2 and Figure 3 The power line of the light source body 220 is connected to the power supply in an orderly manner with the external terminal through the first wire hole 114, the second wire hole 124 and the wiring hole 141, avoiding the messy jumper wires; and the specifications of the terminal are common market specifications.

[0064] It is understood that this arrangement allows the six light source bodies 220 to be focused in advance. Later, when in use, only the focus of the two light module groups 200 needs to be adjusted to achieve focus. The modular design of the light module groups 200 thus configured facilitates the replacement and maintenance of individual modules, reducing long-term operating costs. Furthermore, the illumination angles and rapid focus of the two light module groups 200 can be flexibly adjusted according to different testing requirements, improving the accuracy and applicability of testing.

[0065] In this embodiment, the light source body 220 may be a halogen lamp or the like, and the light source body 220 emits light 221 .

It will be understood that the curved fixing plate 210 is more conducive to focusing the light 221 emitted by the multiple light source bodies 220.

[0067] Optionally, the lamp group module 200 also includes at least one fan 230, which is arranged on the fixing plate 210 and corresponds to at least one light source body 220; at the same time, the fan 230 is installed above the near light source body 220, and the wind direction is upward to avoid the lamp group module 200 below, thereby dissipating the heat of the light source and realizing rapid cooling of the light source body 220.

[0068] In this embodiment, please refer to Figure 1-Figure 5The lamp module 200 further includes a rotating shaft 240. The upper arc surface of the fixing plate 210 of the lamp module 200 is fixed with two stop blocks 211 to the rotating shaft 240. One end of the rotating shaft 240 is slidably connected to the first arc hole 111, and the other end is slidably connected to the second arc hole 121.

[0069] Optionally, a first pressure block 241 and a first bottom block 242 are connected to one end of the rotating shaft 240. The first bottom block 242 is in contact with the inner wall of the first adjustment plate 110, and the first pressure block 241 is in contact with the outer wall of the first adjustment plate 110. The length of the rotating shaft 240 protrudes beyond the first adjustment plate 110 and the second adjustment plate 120. The upper and lower ends of the rotating shaft 240 are flattened, which not only facilitates the adjustment of the illumination angle of the lamp module 200 but also provides a better connection with the stop block 211, the adjustment plate, and the rotating shaft 240.

[0070] In this embodiment, please refer to Figure 1-Figure 5 The lamp module 200 further includes a central shaft 250 . The lower portion of the arc-shaped surface of the fixing plate 210 of the lamp module 200 is fixed with two locking blocks 211 to the central shaft 250 . One end of the central shaft 250 is connected to the first locking hole 113 , and the other end is connected to the second locking hole 123 .

[0071] Optionally, a first locking block 251 and a second locking block 252 are respectively fixed at both ends of the center shaft 250; wherein, the first locking block 251 is fixed to the first adjustment plate 110 by screws, and one end of the center shaft 250 passes through the first locking block 251 and the first locking hole 113 in sequence, and a first locking member (not shown in the figure) axially passes through the first locking block 251 to tighten and lock the center shaft 250; wherein, the second locking block 252 is fixed to the second adjustment plate 120 by screws, and the other end of the center shaft 250 passes through the second locking block 252 and the second locking hole 123 in sequence, and the second locking member axially passes through the second locking block 252 to tighten and lock the center shaft 250.

[0072] The working principle of the lamp group adjustment structure 010 proposed in this utility model is:

[0073] Before use, the power line of the light source body 220 is connected to the external connection terminal in an orderly manner through the first wire hole 114, the second wire hole 124 and the wiring hole 141 to the power supply, avoiding jumper wires and messy wires.

[0074] During use, the light source body 220 is powered on and begins to emit light. The locking screws of the first pressing block 241 and the first bottom block 242, as well as the first and second locking members on the locking block, are loosened. The angle of the light source module's overall light 221 is adjusted based on the volume of the agricultural product by pulling the protruding length of the rotating shaft 240 along the first and second arc-shaped holes 111 and 121. Simultaneously, the two sets of light modules 200 are adjusted to better focus their light 221. After adjusting and focusing the two sets of light modules 200, the locking screws of the first pressing block 241 and the first bottom block 242, as well as the locking screws on the locking block, are tightened.

[0075] In summary, the lamp group adjustment structure 010 proposed in the present invention, by setting a mounting bracket 100, sets at least one first arc hole 111 on the first adjustment plate 110, and sets at least one second arc hole 121 on the second adjustment plate 120, and the two ends of the lamp group module 200 are slidingly connected with the first arc hole 111 and the second arc hole 121 respectively, so that when the product is irradiated, the lamp group module 200 can slide along the first arc hole 111 and the second arc hole 121 to make the irradiation angle of the lamp group module 200 adjustable; the lamp group adjustment structure 010 set in this way can flexibly adjust the irradiation angle and quick focus of the lamp group module 200 according to different detection requirements, thereby improving the accuracy and applicability of the detection.

[0076] Furthermore, by modularizing the lamp group module 200, such a lamp group design facilitates the replacement and maintenance of a single module, thereby reducing long-term operating costs.

[0077] Furthermore, the lamp module 200 is provided with a fan 230, and the mounting bracket 100 is designed as an overall open frame. The combination of the two greatly enhances the heat dissipation effect and maintains the long-term stability of the device.
