[0031] Referring to Figure 1 , Figure 3 , Figure 4 , an embodiment provided by the present invention: a pulsed intense light sterilization and fruit and vegetable disinfection device, including a disinfection box 1 for disinfecting and processing the fruits and vegetables inside. A feeding conveyor belt 21 is fixedly connected to the inner wall of the disinfection box 1 for conveying fruits and vegetables. A quantitative feeding assembly for quantitative feeding is arranged outside the feeding conveyor belt 21 to control the feeding of fruits and vegetables in a certain amount. A fixed column 2 is rotatably connected to the inner wall of the disinfection box 1 for fixing the position of the swinging gear 3. A swinging gear 3 is fixedly connected to the outer wall of the fixed column 2. The swinging of the swinging gear 3 drives the driving plate 20 to swing, so as to turn over the fruits and vegetables above, making the fruits and vegetables receive uniform light.

[0032] A fixing plate 4 is fixedly connected to the top of the swinging gear 3 for driving the swinging gear 3 to swing. A control rod 7 is slidably connected to the inner wall of the fixing plate 4. The other end of the control rod 7 is fixedly connected to a rotating disk 6. The rotation of the rotating disk 6 drives the control rod 7 to rotate, thereby driving the fixing plate 4 to swing. A rotating shaft 5 is fixedly connected to the inner wall of the rotating disk 6 for driving the rotating disk 6 to rotate. One end of the rotating shaft 5 is fixedly connected to the driving end of the motor on the inner wall of the disinfection box 1, facilitating the driving of the rotating disk 6. Two swinging columns 24 are slidably connected to the inner wall on one side of the disinfection box 1, facilitating driving the driving plate 20 to swing back and forth. Swing racks 8 are fixedly connected to the outer walls of the two swinging columns 24. The swinging gear 3 and the swing racks 8 are meshed with each other. The swinging of the swinging gear 3 drives the swing racks 8 to swing, thereby driving the driving plate 20 and the roller 25 to swing to turn over the fruits and vegetables to make them receive uniform light.

[0033] Both ends of the two swinging columns 24 are fixedly connected to a driving plate 20. A plurality of driving ends inside the driving plate 20 are fixedly connected to a plurality of rollers 25 for conveying the disinfected fruits and vegetables out. A plurality of pulsed intense light lamps 23 are fixedly connected to the inner wall of the disinfection box 1 for disinfecting the surface of the fruits and vegetables by pulsed intense light. A baffle 17 is fixedly connected to the outer wall of the fixed pile 9. The top of the baffle 17 is slidably connected to the bottom of the quantitative storage box 11 to prevent the fruits and vegetables inside the quantitative storage box 11 from falling. A control panel 19 is arranged on the inner wall of the disinfection box 1 for facilitating the operation of the staff. An output conveyor belt 22 is fixedly connected to the inner wall of the disinfection box 1 for conveying the disinfected fruits and vegetables out;

[0034] Reference Figure 1 , Figure 2 , Figure 3 , the quantitative feeding assembly includes a bracket 16 which is fixedly connected to the outer wall of the feeding conveyor belt 21 for fixing the quantitative feeding assembly. Two electric push rods 10 are slidably connected to the inner wall of the bracket 16. When the fruits and vegetables in the quantitative storage box 11 reach a certain amount, they push the quantitative storage box 11 and move it above the feeding conveyor belt 21. A fixed pile 9 is fixedly connected to the outer wall of the bracket 16. The fixed pile 9 is used to connect the quantitative feeding assembly and also has a driving device inside for driving the electric push rods 10 and the rotating rod 12. The tops of the two electric push rods 10 are fixedly connected to the driving ends of the motors on the inner wall of the fixed pile 9, which is convenient for driving the electric push rods 10 to push out the quantitative storage box 11.

[0035] The other ends of the two electric push rods 10 are both fixedly connected to a quantitative storage box 11 for storing the fruits and vegetables to be illuminated. The bottom of the quantitative storage box 11 is rotatably connected to a bottom plate 14. When the quantitative storage box 11 is pushed out, the baffle 17 no longer supports the bottom plate 14, and the fruits and vegetables in the quantitative storage box 11 fall onto the surface of the feeding conveyor belt 21. A fixed frame 18 is fixedly connected to the outer wall of the fixed pile 9, and a feeding box 15 is fixedly connected to the outer wall of the fixed frame 18 for storing the fruits and vegetables to be disinfected. The bottom of the feeding box 15 is rotatably connected to two flap plates 13. When the fruits and vegetables in the quantitative storage box 11 reach a certain amount, the flap plates 13 turn upward to close. The bottoms of the two flap plates 13 are in contact with the quantitative storage box 11. Rotating rods 12 are fixedly connected to the inner walls of the two flap plates 13, which is convenient for controlling the rotation of the flap plates 13 to make the fruits and vegetables fall into the quantitative storage box 11. The tops of the rotating rods 12 are fixedly connected to the driving ends of the motors on the inner wall of the fixed pile 9.

[0036] Working principle: When it is necessary to disinfect the fruits and vegetables, the fruits and vegetables are put into the feeding box 15. The motor inside the fixed pile 9 is started through the control panel 19. The motor controls the flap plates 13 to open downward through the rotating rods 12, and the fruits and vegetables fall into the quantitative storage box 11. When the fruits and vegetables in the quantitative storage box 11 reach a certain amount, the driving motor controls the flap plates 13 to close upward, and the fruits and vegetables no longer fall. At this time, another driving motor inside the fixed pile 9 drives the push rod to push out the quantitative storage box 11, so that the baffle 17 cannot completely support the bottom plate 14, and the bottom plate 14 opens at an inclined angle. At this time, the fruits and vegetables in the quantitative storage box 11 fall onto the feeding conveyor belt 21 and are sent into the disinfection box 1 by the feeding conveyor belt 21 for light disinfection.

[0037] After the feeding conveyor belt 21 is started, the motor inside the disinfection box 1 drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the rotating disk 6 to rotate, and the rotation of the rotating disk 6 drives the control rod 7 to rotate, causing the fixed rod to drive the oscillating gear 3 to rotate towards the feeding conveyor belt 21. At the same time, the driving plate 20 drives the roller 25 to rotate. After all the fruits and vegetables are conveyed above the roller 25, the roller 25 stops rotating. At this time, the rotating shaft 5 drives the rotating disk 6 and the control rod 7 to rotate 360 degrees, causing the fruits and vegetables on the surface of the roller 25 to be turned over, so that the fruits and vegetables are fully exposed to light to achieve the purpose of sufficient disinfection. When the disinfection is completed, the rotating shaft 5 drives the rotating disk 6 and the control rod 7 to rotate, swinging the oscillating rack 8 in the reverse direction of the discharge conveyor belt 22 to contact it, and conveying the disinfected fruits and vegetables out.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
