[0002] Potatoes are a common food with rich nutritional value. Blackheart disease is a common internal disease in potato shipments. Blackheart disease is caused by insufficient oxygen supply to the tuber's internal tissues, leading to respiratory failure. When the disease occurs, the center of the tuber becomes gray-black and radiates outwardly, but the appearance remains normal. Current nondestructive testing technologies are based on rapid, visible / near-infrared diffuse transmission spectroscopy. Most techniques collect spectra along either the vertical or horizontal axis of the potato. Different illumination angles can affect the results of blackheart disease spectral testing. Comprehensive analysis of spectra from multiple angles can improve detection accuracy.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] refer to Figure 1-Figure 5 A spectrum acquisition device for multi-angle detection of potato blackheart disease is shown, comprising a detection black box 1, a spectrometer, a computer, and a light source 20. It should be noted that, in this embodiment, the installation method of the spectrometer and the computer can refer to the technical content adopted in a spectrum acquisition device for multi-angle detection of potato blackheart disease disclosed in Chinese Patent Publication No. CN213875422U in the prior art, which will not be described in detail here. A clamping mechanism is provided in the detection black box 1 for fixing potatoes. The light source 20 is provided in the detection black box 1 by an adjustment mechanism for adjusting the position of the light source 20.

[0027] The clamping mechanism includes two rectangular slides 2, which are slidably installed in the detection black box 1 through a sliding assembly. The opposite sides of the two rectangular slides 2 are provided with U-shaped plates 6 through a telescopic assembly. The two U-shaped plates 6 are provided with a flip assembly. The flip assembly includes two rotating shafts 9. A rectangular cavity is opened in the U-shaped plate 6. Two circular holes are opened on the inner wall of the side of the rectangular cavity. The two rotating shafts 9 are rotatably installed in the two circular holes respectively. The two rotating shafts 9 are connected by a linkage unit. Silicone sleeves 12 are fixed on the two rotating shafts 9.

[0028] The adjustment mechanism includes a fixed block 13, which is fixedly installed on the top of the detection black box 1. An arc-shaped plate 14 is provided at the bottom of the fixed block 13. A U-shaped slider 15 is slidably installed on the arc-shaped plate 14 through a limiting component. A moving component is commonly provided between the U-shaped slider 15 and the arc-shaped plate 14. The light source 20 is fixedly installed at the bottom of the U-shaped slider 15.

[0029] With the above structure, when in use, first, the two rectangular slides 2 are driven by the sliding assembly to move toward each other to a suitable position, then the potatoes are placed on the multiple silicone sleeves 12, and the two U-shaped plates 6 are driven by the sliding assembly to continue to move. With the cooperation of the telescopic assembly, potatoes of different sizes are clamped, and then the potatoes are detected by the light source, spectrometer, and computer. When adjustment is required, the multiple rotating shafts 9 and the silicone sleeves 12 can be driven to rotate synchronously by the flip assembly, so that the potatoes are flipped under the action of the telescopic assembly, which facilitates the detection of the direction of the potatoes. When the position of the light source 20 needs to be adjusted, the U-shaped slider 15 can be driven by the moving assembly to slide along the curved plate 14, so that the front and rear ends of the potatoes can be illuminated for detection.

[0030] Example 2

[0031] like Figure 2 As shown, the relative inner walls of the detection black box 1 are provided with sliding grooves, and a transmission cavity is provided in the detection black box 1. Two rotating holes are provided on the side inner walls of the transmission cavity. A bidirectional screw rod 3 is rotatably installed in the two rotating holes. The two bidirectional screw rods 3 are connected by a transmission unit, and the two rectangular slides 2 are threadedly installed on the two bidirectional screw rods 3. With this arrangement, the rectangular slide 2 can be driven to realize the horizontal movement function through the rotation of the two bidirectional screw rods 3.

[0032] Specifically, when it is necessary to drive the two rectangular slides 2 to move synchronously, the two bidirectional screw rods 3 can be rotated, thereby driving the two rectangular slides 2 to move synchronously toward or away from each other under the action of the threads.

[0033] like Figure 3 As shown, the transmission unit includes two first sprockets 4, which are respectively fixedly sleeved on two bidirectional screw rods 3, and the two first sprockets 4 are commonly meshed with a first chain. A drive motor 5 is fixedly installed on the side of the detection black box 1, and the output shaft of the drive motor 5 is connected to the end of one of the bidirectional screw rods 3. This arrangement can drive the two bidirectional screw rods 3 to rotate synchronously through the meshing action of the two first sprockets 4 and the first chain.

[0034] Specifically, the driving motor 5 is started to drive one of the bidirectional screw rods 3 to rotate, and then the other bidirectional screw rod 3 is driven to rotate synchronously under the meshing action of the two first sprockets 4 and the first chain, to prevent the rectangular slide 2 from getting stuck during horizontal movement.

[0035] Example 3

[0036] like Figure 3As shown, the telescopic assembly includes a damping telescopic rod 7, one end of the damping telescopic rod 7 is fixedly mounted on the side of the rectangular slide 2, and the other end of the damping telescopic rod 7 is fixedly mounted on the side of the U-shaped plate 6. The outer wall of the peripheral side of the damping telescopic rod 7 is provided with a compression spring 8, one end of the compression spring 8 is fixedly mounted on the inner wall of the end of the damping telescopic rod 7, and the other end of the compression spring 8 is fixedly mounted on the side of the U-shaped plate 6. In this way, the damping telescopic rod 7 can be set up to clamp potatoes of different sizes through its telescopic function, and when the potatoes are turned over, the potatoes can always be better limited by its telescopic effect to prevent them from falling.

[0037] Specifically, when clamping potatoes, potatoes of different sizes can be clamped through the telescopic function of the damping telescopic rod 7, and when the potatoes are turned over, the elastic effect of the damping telescopic rod 7 and the compression spring 8 can always provide a good clamping function for the potatoes to prevent them from falling.

[0038] like Figure 3 As shown, the linkage unit includes two second sprockets 10, which are respectively fixedly sleeved on the two rotating shafts 9, and the second chains are installed on the two second sprockets 10 in common meshing manner. A flip motor 11 is fixedly installed on the side of the U-shaped plate 6, and the output shaft of the flip motor 11 is connected to the end of one of the rotating shafts 9. With this arrangement, the two rotating shafts 9 can be driven to rotate synchronously through the arrangement of the two second sprockets 10 and the second chain.

[0039] Specifically, when the flipping motor 11 drives one of the rotating shafts 9 to rotate, the meshing action of the two second sprockets 10 and the second sprocket drives the other rotating shaft 9 to rotate synchronously, thereby driving the potatoes to flip through the rotation of the two silicone sleeves 12.

[0040] Example 4

[0041] like Figure 5 As shown, the limiting assembly includes two arc-shaped limiting bars 16, and arc-shaped grooves are provided on both sides of the arc-shaped plate 14. The two arc-shaped limiting bars 16 are slidably installed in the two arc-shaped grooves respectively, and the side portions of the two arc-shaped limiting bars 16 that are away from each other are fixedly connected to the relative inner walls of the U-shaped slider 15 respectively. In this way, the U-shaped slider 15 can be limited by the setting of the arc-shaped limiting bars 16 to prevent the U-shaped slider 15 from falling off.

[0042] Specifically, when the U-shaped slider 15 needs to be moved, the arc-shaped limiting strip 16 slides in the arc-shaped groove to limit the U-shaped slider 15 and prevent the U-shaped slider 15 from deviating in direction when moving.

[0043] like Figure 5As shown, the moving component includes a rack 17, which is fixedly arranged on the inner wall of the circumference of the arc plate 14, and a mounting shaft is installed on the relative inner wall of the U-shaped slider 15 for common rotation. A gear 18 is fixedly sleeved on the mounting shaft, and the gear 18 is meshed with the rack 17. An adjusting motor 19 is fixedly installed on the side of the U-shaped slider 15, and the output shaft of the adjusting motor 19 is fixedly connected to the end of the mounting shaft. In this way, the U-shaped slider 15 can be driven to realize the moving function through the meshing action of the gear 18 and the rack 17.

[0044] Specifically, when the U-shaped slider 15 needs to be moved, the adjusting motor 19 is started to drive the rotating shaft and the gear 18 to rotate, and then through the meshing action of the motor and the rack 17, the U-shaped slider 15 is driven to achieve the movement function.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
