Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a fruit processing, grading, conveying, and sorting device. Background Technology

[0002] Dried fruit is a food made from fresh fruit through sun-drying or baking. Dehydration concentrates the nutritional essence of the fruit, making it an important supplement to a diversified diet. In the dried fruit processing technology, the conveying and sorting of dried fruit is a key link in the large-scale production of dried fruit. It is necessary not only to remove dried fruit contaminated by insects, but also to screen out the debris in the dried fruit according to size differences.

[0003] For example, Chinese patent CN217043371U discloses a dried fruit sorting machine. This device uses a screen cylinder and a motor to screen the dried fruit that is transported into the screen cylinder by a conveyor belt, so that the residue is removed by the screen. The spiral blades are used to screen and transport the dried fruit at the same time, which can effectively remove the residue and continuously feed and unload the fruit, making it convenient for workers to operate and improving work efficiency.

[0004] Existing dried fruit sorting equipment often uses screens to separate debris from dried fruit. However, when lightweight dried fruit is conveyed and screened through tubular screens, there will be continuous collisions and contact between the dried fruit and the screen, as well as between the dried fruit themselves. Under the impact of these collisions, the dried fruit will break, which will increase the breakage rate during the conveying and sorting process and thus have an adverse effect on the precision of the finished dried fruit product.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This solution, by setting up a pushing component and using gas propulsion, can effectively reduce the damage to dried fruit during the conveying process and also effectively reduce the impact on the dried fruit, thereby effectively reducing the breakage rate during the dried fruit processing. The dried fruit will generate irregular movement under the blowing of gas, which can irradiate and detect different positions on the surface of the dried fruit, which helps to further improve the detection error. Furthermore, by intermittently expelling compressed air, the amount of compressed air lost during the dried fruit screening process can be effectively reduced, which helps to reduce the cost of dried fruit conveying and screening.

[0018] 2. This solution uses a material distribution component to lift the dried fruit upwards through the continuous rotation of the conveyor rollers.

[0019] 3. This solution uses a sorting component. The dried fruit inside the sorting box slides down sequentially under gravity. Dried fruit of different sizes will fall down at different positions in the sorting trough, thus enabling the sorting of dried fruit based on size differences. The dried fruit then falls into the distribution box for separate collection, which helps to further improve the sorting accuracy of dried fruit. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8 The present invention provides a technical solution:

[0033] A fruit processing grading and sorting device includes a conveying pipe 19 and a fixed frame 18 sleeved on the outside of the conveying pipe 19. An air guide pipe 13 is fixedly connected to the outer surface of the left end of the conveying pipe 19. A pushing assembly is provided inside the conveying pipe 19. The pushing assembly includes a sealing sleeve 52 fixedly connected to the inner surface of the conveying pipe 19. A sliding sleeve 50 is slidably connected to the inner surface of the sealing sleeve 52. A push plate 49 is fixedly connected to the right end of the sliding sleeve 50. The side of the sliding sleeve 50 away from the push plate 49 is open. A spring 48 is fixedly connected to the outer surface of the left end of the push plate 49. The end of the spring 48 away from the push plate 49 is fixedly connected to the inner surface of the conveying pipe 19. A vent hole 51 is opened through the outer surface of the sliding sleeve 50. A guide pipe 17 is fixedly connected to the upper side of the outer surface of the conveying pipe 19.

[0034] The number of conveying pipes 19 is several and arranged in a parallel array. A detection lens 30 is fixedly connected to the upper side of the inner surface of the fixing frame 18, and a light source 31 is provided on the lower side of the inner surface of the fixing frame 18. One end of the conveying pipe 19 is closed and the other end is open. An air storage tank 12 is fixedly connected to the lower end of the air guide pipe 13. The conveying pipe 19 is made of transparent material. The air storage tank 12 is connected to the air compressor through a pipe. An inlet 53 is opened through the left side of the upper outer surface of the conveying pipe 19. The inlet 53 is connected to the inside of the guide pipe 17.

[0035] By adopting the above technical solution, when the conveying and sorting device sorts and conveys dried fruits such as jujubes, the dried fruits are sequentially placed into the conveying pipe 19. Compressed air inside the air storage tank 12 is injected into the conveying pipe 19 through the air guide pipe 13. The air flow inside the conveying pipe 19 can push the dried fruits to move in the middle part of the conveying pipe 19. Compressed air generated by the air compressor is injected into the air storage tank 12 through the pipeline, thereby replenishing the compressed air inside the air storage tank 12. In order to reduce the additional loss of compressed air, a pushing component is set up. The conveying pipe 19 is elastically supported by the push plate 49 by the spring 48. Under the elastic force of the spring 48, the push plate 49 will stick to the right end of the air guide pipe 13. The dried fruits are guided by the guide pipe 17. Under the influence of the air pressure, the dried fruit falls into the conveying pipe 19 through the inlet 53 and is located to the right of the push plate 49. When compressed air is injected from the air tank 12 into the air guide pipe 13, the gas pressure inside the air guide pipe 13 gradually increases. At this time, the compressed air will remain inside the air guide pipe 13 and will not be discharged into the conveying pipe 19, thereby reducing the gas resistance during the feeding process and helping to improve the feeding accuracy. At this time, the push plate 49 will drive the sliding sleeve 50 to move synchronously under the action of gas pressure. During the movement of the push plate 49, the air guide pipe 13 is slidably supported by the sliding sleeve 50 through the sealing sleeve 52. The push plate 49 pushes the dried fruit a certain distance inside the conveying pipe 19, making the dried fruit away from the area of ​​the inlet 53. When the air permeability of the surface of the sliding sleeve 50 is reduced, the dried fruit will be able to move further away from the area of ​​the inlet 53. After the hole 51 disengages from the sealing sleeve 52, the gas inside the air duct 13 is discharged into the conveying pipe 19 through the vent 51. The compressed air flowing inside the conveying pipe 19 propels the dried fruit, allowing it to move smoothly within the pipe. Using gas propulsion effectively reduces damage to the dried fruit during transport and minimizes impacts, thus reducing breakage during processing. The mounting bracket 18 is used to fix the detection lens 30 and the light source 31. When the dried fruit moves to the inside of the mounting bracket 18, the light source 31 illuminates the fruit in conjunction with the detection lens 30. The conveying pipe 19 is made of transparent material. The system is designed to ensure stable light penetration. The control system then analyzes and judges the shape of the dried fruit, enabling accurate detection of defective products. By setting up a pushing component, the resistance to fruit feeding is reduced, which not only improves the feeding and detection accuracy of the dried fruit, but also pushes the dried fruit with the push plate 49. This reduces the risk of compressed gas blowing the dried fruit onto the upper side of the conveying pipe 19. At the same time, the dried fruit will move irregularly under the blowing of gas, which allows for irradiation and detection of different positions on the surface of the dried fruit, which helps to further improve the detection error. Furthermore, by intermittently expelling the compressed air, the amount of compressed air lost during the fruit screening process can be effectively reduced, which helps to reduce the cost of fruit conveying and screening.

[0036] Specifically, such as Figure 2, Figure 5 and Figure 7 As shown, a receiving hopper 15 is fixedly connected to the outer surface of the left end of the guide pipe 17. A material distribution component is provided inside the receiving hopper 15. The material distribution component includes a guide plate 16 fixedly connected to the outer surface of the upper end of the receiving hopper 15. The number of guide plates 16 is several sets and they are staggered with the conveying pipe 19. An installation plate 14 is fixedly connected to the outer surface of the lower end of the receiving hopper 15.

[0037] A slot 32 is provided through the upper outer surface of the receiving hopper 15. A drive rod 34 is rotatably connected to the outer surface of the mounting plate 14. A conveying wheel 33 is fixedly connected to the outer surface of the drive rod 34. The conveying wheel 33 passes through the slot 32 to the upper side of the receiving hopper 15. The outer surface of the conveying wheel 33 is wavy. There are several sets of slots 32, which are staggered with the guide plate 16.

[0038] A second drive rod 35 is rotatably connected to the outer surface of the air guide pipe 13. An impeller 47 is fixedly connected to the outer surface of the second drive rod 35. The impeller 47 is located inside the air guide pipe 13. A second synchronous pulley 38 is fixedly connected to the outer surface of the second drive rod 35. A first synchronous pulley 36 is fixedly connected to the outer surface of the first drive rod 34. A synchronous belt 37 meshes with the outer surfaces of the first synchronous pulley 36 and the second synchronous pulley 38 for transmission.

[0039] By adopting the above technical solution, when compressed air flows inside the air guide pipe 13, it blows the impeller 47. At this time, the impeller 47 drives the drive rod 35 to rotate. The air guide pipe 13 and the drive rod 35 are sealed by a sealing ring to reduce the risk of compressed air leakage. During the rotation of the drive rod 35, it drives the synchronous pulley 38 to rotate synchronously. The synchronous pulleys 36 and 38 are connected by the synchronous belt 37 to maintain synchronous rotation. During the rotation of the synchronous pulley 36, it drives the drive rod 34 to rotate. The receiving hopper 15 supports the drive rod 34 through the mounting plate 14, and the drive rod 34 drives the material conveying. As the conveyor wheel 33 rotates, the dried fruit to be sorted is first placed on the upper side of the receiving hopper 15. The guide plate 16 on the upper side of the receiving hopper 15 separates the dried fruit on the upper side of the guide plate 16, allowing the dried fruit to enter between the two sets of guide plates 16. The conveyor wheel 33 is located inside the slot 32. During the rotation of the conveyor wheel 33, its outer surface lifts the dried fruit upward. As the conveyor wheel 33 continues to rotate, it will transport the dried fruit one by one into the traction plate, thereby achieving orderly placement of the dried fruit. This reduces the risk of dried fruit blocking each other during the fruit detection process, effectively improving the sorting and conveying accuracy of the dried fruit and helping to reduce subsequent detection errors.

[0040] Specifically, such as Figure 4 and Figure 6As shown, a detection component is provided inside the fixing frame 18. The detection component includes a sealing groove 39 that runs through the lower side of the outer surface of the conveying pipe 19. A storage groove 41 is embedded in the lower side of the outer surface of the conveying pipe 19. A folding plate 42 is fixedly connected to the inner surface of the storage groove 41. A sealing plate 40 is fixedly connected to the upper outer surface of the folding plate 42. The sealing plate 40 is located inside the sealing groove 39. The folding plate 42 is made of elastic material.

[0041] An installation groove 43 is embedded on the lower side of the inner surface of the fixed frame 18. An extrusion block 44 is slidably connected to the inner surface of the installation groove 43. A baffle 46 is fixedly connected to the inner surface of the installation groove 43. A cylinder 45 is fixedly connected to the outer surface of the baffle 46. The telescopic rod of the cylinder 45 is fixedly connected to the outer surface of the extrusion block 44. The upper side of the extrusion block 44 is hinged to the lower outer surface of the sealing plate 40. A discharge pipe 25 is fixedly connected to the lower outer surface of the fixed frame 18. The discharge pipe 25 is connected to the interior of the fixed frame 18.

[0042] By adopting the above technical solution, the fixing frame 18 is used to slide and support the extrusion block 44 through the mounting groove 43. The fixing frame 18 is fixedly installed on the cylinder 45 through the baffle 46. When the detection lens 30 detects defective dried fruit, the sorting device control system will control the cylinder 45 to retract. At this time, the cylinder 45 will drive the extrusion block 44 to slide towards the baffle 46 side inside the mounting groove 43. During the movement, the extrusion block 44 will pull the sealing plate 40. The conveying pipe 19 is used to fix the folding plate 42 through the receiving groove 41. Under the action of tension, the sealing plate 40 will flip around the folding plate 42 as the fulcrum, thereby sealing the plate. When the sealing groove 39 on the surface of the conveying pipe 19 is disengaged from the plate 40, the defective dried fruit inside the conveying pipe 19 will fall downward through the sealing groove 39 and fall into the discharge pipe 25 under the guidance of the sealing plate 40. At this time, some gas will be discharged downward through the sealing groove 39. The gas push can accelerate the falling of the dried fruit. Then the cylinder 45 moves in the opposite direction and pushes the extrusion block 44 to move in the opposite direction, so that the sealing plate 40 enters the sealing groove 39 to seal the sealing groove 39. This enables the rapid sorting and removal of defective dried fruit, which helps to achieve rapid screening of dried fruit and reduces the residual rate of defective products in dried fruit.

[0043] Specifically, such as Figure 1 and Figure 3 As shown, a support leg 11 is fixedly connected between the outer surface of the gas storage tank 12 and the discharge pipe 25. A bracket 28 is fixedly connected to the outer surface of the discharge pipe 25 away from the support leg 11. A sorting box 20 is fixedly connected to the outer surface of the bracket 28. A bracket 29 is fixedly connected to the upper outer surface of the support leg 11. The upper outer surface of the bracket 29 is fixedly connected to the conveying pipe 19.

[0044] The sorting box 20 is provided with a sorting component inside. The sorting component includes a partition 21 that is fixedly connected to the upper outer surface of the sorting box 20. The partition 21 is in several groups and is distributed in a parallel array. The sorting box 20 is set at an angle. A sorting groove 26 is opened through the upper outer surface of the sorting box 20. The outer surface of the sorting groove 26 has a trapezoidal structure.

[0045] A baffle 27 is fixedly connected to the inner surface of the sorting trough 26. The baffle 27 consists of several groups and is arranged in a parallel array. A material distribution box 22 is fixedly connected to the lower outer surface of the sorting box 20. Support legs 23 and 34 are fixedly connected to the lower outer surface of the sorting box 20. The height of support leg 23 is higher than that of support leg 324.

[0046] By adopting the above technical solution, the first support leg 11 supports the gas storage tank 12 and the discharge pipe 25 through the bracket, the second support leg 23 and the third support leg 24 are used to fix and support the sorting box 20, so that the sorting box 20 is kept in an inclined position. The discharge pipe 25 can further improve the structural strength of the sorting box 20 through the first bracket 28, and the second bracket 29 can support the conveying pipe 19, so that the position of the conveying pipe 19 is kept stable. The dried fruit inside the conveying pipe 19 will fall to the surface of the sorting box 20 under the push of the gas. The partition 21 can divide the internal space of the sorting box 20, so that the dried fruit can slide down in sequence under the action of gravity. When the dried fruit moves to the sorting trough 26 area, since the sorting trough 26 has a trapezoidal structure, dried fruit of different sizes will fall down at different positions in the sorting trough 26, so that the dried fruit can be screened according to the size difference of the dried fruit. After the dried fruit falls into the sorting box 22 for separate collection, it helps to further improve the sorting accuracy of the dried fruit.

[0047] Working Principle: When the dried fruit conveying and sorting device is working, the dried fruit to be sorted is first placed on the upper side of the receiving hopper 15. The dried fruit will enter between the two sets of guide plates 16. During the rotation of the conveying wheel 33, its outer surface will lift the dried fruit upwards. As the conveying wheel 33 continues to rotate, it will convey the dried fruit one by one into the traction plate. Under the guidance of the traction plate, the dried fruit will enter the conveying pipe 19 in sequence. When compressed air is injected from the air tank 12 into the air guide pipe 13, the push plate 49 will drive the sliding sleeve 50 to move synchronously under the gas pressure. The push plate 49 will push the dried fruit a certain distance inside the conveying pipe 19, so that the dried fruit is away from the inlet 53 area. The gas inside the air guide pipe 13 will be discharged into the conveying pipe 19 through the vent 51. The compressed air flowing inside the conveying pipe 19 will push the dried fruit, so that the dried fruit can be conveyed through the conveying pipe 19. 9. The internal movement is smooth. When the dried fruit moves to the inside of the fixed frame 18, the light source 31 will irradiate the dried fruit and cooperate with the detection lens 30 to irradiate the dried fruit. The conveying pipe 19 is made of transparent material to ensure stable light transmission. Then, the control system analyzes and judges the shape of the dried fruit. When the detection lens 30 detects defective dried fruit, the cylinder 45 will drive the squeezing block 44 to slide towards the baffle 46 inside the mounting groove 43. During the movement, the squeezing block 44 will pull the sealing plate 40. The defective dried fruit inside the conveying pipe 19 will fall down through the sealing groove 39, which can realize the rapid sorting and removal of defective dried fruit. The dried fruit inside the sorting box 20 slides down in sequence under the action of gravity. Dried fruit of different sizes will fall down at different positions in the sorting groove 26, so as to screen the dried fruit according to the size difference.
