Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3 As shown, this utility model provides an embodiment of an automatic grading and cutting device for fruit and vegetable freezing processing, including an outer shell 1. The outer shell 1 serves as the main frame of the entire device, with a robust structure that provides a stable mounting foundation for the various internal components. A limiting conveying assembly is fixedly connected to the top left side of the outer shell 1. The conveying assembly includes a feed hopper 2 and two baffles 3. The feed hopper 2 serves as the inlet for fruits and vegetables entering the device, and its position is rationally designed to conveniently receive fruits and vegetables before freezing processing. The bottom of the feed hopper 2 is fixedly connected to the top of the outer shell 1, ensuring a secure and reliable installation. The baffles 3 are externally fixedly connected to the inside of the outer shell 1, providing initial guidance and shielding for the fruits and vegetables entering the device.
[0034] Multiple limiting blocks 4 are fixedly connected inside the outer shell 1, which limit the range of motion of the rotating block 5. The rotating block 5 is rotatably connected inside the limiting block 4, and the rotating block 5 can rotate flexibly inside the limiting block 4. A grading rod 6 is fixedly connected to the right side of the rotating block 5, which is used to grade fruits and vegetables before freezing.
[0035] Reference Figure 1 and Figure 2 , Figure 4 As shown, a cylinder 7 is fixedly connected to the front side of the outer shell 1. The cylinder 7 serves as the power source for the swinging of the grading rod 6, and its performance is stable and reliable. A connecting rod 8 is fixedly connected to the drive end of the cylinder 7, which transmits the power of the cylinder 7 to the grading rod 6. The external part of the connecting rod 8 is slidably connected to the inside of the slide groove 9, which provides guidance for the movement of the connecting rod 8. The external part of the connecting rod 8 is fixedly connected to the inside of multiple grading rods 6, ensuring that the connecting rod 8 can drive the grading rods 6 to move together. A slide groove 9 is provided on the rear side of the outer shell 1. The position and size of the slide groove 9 are reasonably designed to meet the movement requirements of the connecting rod 8. Two placement slots 10 are provided on the front side of the outer shell 1, which provide space for the installation of the collection plate 11. The collection plate 11 is rotatably connected inside the placement slot 10. The collection plate 11 is used to collect the graded fruits and vegetables. The bottom of the collection plate 11 contacts the top of the fixing block 12, which provides support for the collection plate 11.
[0036] Reference Figure 5As shown, multiple fixing blocks 12 are fixedly connected inside the outer shell 1. The fixing blocks 12 are reasonably distributed to ensure the stability of the collecting plate 11. A spring-loaded assembly for pushing is fixedly connected to the top of each fixing block 12. Each spring-loaded assembly includes a slide rod 13, which guides the movement of the spring 14. The bottom of the slide rod 13 is fixedly connected to the top of the fixing block 12, ensuring that the slide rod 13 is securely and reliably installed. A spring 14 is sleeved on the outside of the slide rod 13, providing elastic support for the collecting plate 11. One side of the spring 14 is fixedly connected to the bottom of the collecting plate 11, and the other side of the spring 14 is fixedly connected to the top of the fixing block 12, ensuring that the spring 14 can function properly.
[0037] Reference Figures 6 to 7 As shown, two connecting shells 15 are fixedly connected to the front of the outer shell 1, providing installation space for the conveyor belts 16 and other components. Two conveyor belts 16 are installed inside the connecting shells 15, which transport the graded fruits and vegetables to the cutting position. A mounting block 17 is fixedly connected to the top of the connecting shell 15, providing support for the installation of the limiting shaft 18 and the cutting plate 19. The limiting shaft 18 is rotatably connected inside the mounting block 17, ensuring the stable rotation of the cutting plate 19. The cutting plate 19 is fixedly connected to the outside of the limiting shaft 18, and is used to cut the fruits and vegetables.
[0038] A motor 20 is fixedly connected to the top of the connecting shell 15. The motor 20 serves as the power source for the rotation of the cutting plate 19, and its power is moderate enough to meet the cutting requirements. Gear 23 is externally rotatably connected to the inside of the connecting shell 15, ensuring its normal operation. The left and right sides of the cutting plate 19 are rotatably connected to the adjacent sides of the two conveyor belts 16, enabling the cutting plate 19 to work in coordination with the conveyor belts 16. A rotating rod 21 is fixedly connected to the motor 20, transmitting the power of the motor 20 to gear 22. Gear 22 is externally fixedly connected to the rotating rod 21, and gear 22 and gear 23 are meshed together, achieving the rotation of the cutting plate 19 through gear transmission.
[0039] Working principle: Before freezing fruits and vegetables, they need to be graded. This is done by feeding them through the hopper 2, and then the baffle 3 inside the outer shell 1 blocks the fruits and vegetables before freezing. This causes the fruit and vegetable hopper to fall to the left side of multiple grading rods 6. Then, the cylinder 7 is started, which generates power to drive the connecting rod 8, causing the multiple grading rods 6 to swing back and forth. This causes the grading rods 6 to swing back and forth inside the limiting block 4 in conjunction with the rotating block 5. This allows the fruits and vegetables before freezing to slide from left to right on the top of the multiple grading rods 6. The gap between the grading rods 6 increases as they move to the right, thus enabling the grading of the fruits and vegetables before freezing.
[0040] The graded fruits and vegetables then fall onto the top of the collecting plate 11. The collecting plate 11 is supported by the fixing block 12, while the sliding rod 13 and spring 14 provide elastic support and assistance to the collecting plate 11.
[0041] After grading, the fruits and vegetables enter the cutting stage. Two conveyor belts 16 are installed inside the connecting shell 15, forming a V-shape. The conveyor belts 16 transport the fruits and vegetables to the cutting position. A limit shaft 18 and a cutting plate 19 are installed on the mounting block 17. Then, the motor 20 is started, causing the motor 20 to drive the gear 22 to rotate through the rotating rod 21. The gear 22 meshes with the gear 23, thereby driving the cutting plate 19 to rotate between the two conveyor belts 16, and then quickly cutting the fruits and vegetables.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
