Description

Technical Field

[0001] This invention relates to the field of agricultural equipment technology, and in particular to a dry automatic lychee sorting device. Background Technology

[0002] Lychee, a cultivated fruit tree native to subtropical regions, is rich in nutrients, containing glucose, sucrose, protein, fat, and vitamins A, B, and C, as well as folic acid, arginine, tryptophan, and other nutrients beneficial to human health. Therefore, it is widely loved. Lychee varieties vary, with larger, sweeter fruits commanding higher prices than smaller ones. After harvesting, farmers sort the lychees by size and color, setting different prices for each grade. After picking, lychees are typically collected in boxes before being poured into sorting equipment. While many lychee sorting devices exist on the market, they generally lack automatic unloading mechanisms. This requires manual labor to unload the boxes, which can easily lead to back or hand injuries for operators.

[0003] The technical content disclosed in the Chinese patent document (application number: CN201820368922.1, patent name: A screening and sorting machine suitable for selenium-rich lychees) is as follows: This utility model discloses a screening and sorting machine suitable for selenium-rich lychees, including a device body, a feed inlet, and a tail outlet. The feed inlet is located at the top center of the device body and extends through the device body. The tail outlet is located at the bottom center of the device body and extends through the device body. A primary screening trough is located inside the upper part of the device body and is fixedly connected to the device body. This screening and sorting machine for selenium-rich lychees features adjustable-size, flexible sorting holes in each screening trough. The feed inlet of each screening trough corresponds to the sorting hole of the next screening trough. The multi-stage screening design allows for complete separation of lychees of different sizes, accurately dividing them into multiple batches for more thorough screening. The flexible sorting holes also prevent damage to the lychees during sorting.

[0004] As can be seen from the above implementation plan, the sorting machine is equipped with multiple screening slots to screen lychees, but it is not equipped with an automatic unloading device. Therefore, every time lychees need to be sorted, the operator has to manually lift the whole box of lychees and pour them into the sorting machine. Manually handling lychees is not only labor-intensive and unsafe, but also inefficient. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing technologies by setting up a conveyor line before the lychee size sorting area, with a flipping component above the conveyor line. Operators only need to place the entire box of lychees on the conveyor line, which then transports the lychees to the flipping component. The flipping component flips the box full of lychees in two steps, allowing the lychees to slide out of the box onto the conveyor line. This saves the manual process of unloading lychees, reduces the labor intensity of workers, improves the working efficiency of the sorting device, and also ensures that the lychees are not damaged by impact or compression during the unloading process.

[0050] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0051] like Figures 1 to 17As shown, a dry-type automatic lychee sorting device is used for automatic sorting of lychees. This device is also equipped with an automatic unloading function, which reduces the workload of operators and increases the lychee sorting speed. It includes a conveyor line 1, a tilting component 2 and an empty box recycling component 3 above the conveyor line 1. One end of the empty box recycling component 3 is connected to a recycling conveyor component 4. One end of the conveyor line 1 is connected to a manual sorting area 6, and the other end of the manual sorting area 6 is connected to a size screening area 7. The other end of the size screening area 7 is connected to a large particle color identification area 8. Below the size screening area 7 is a small particle transport area 9, which is connected to a small particle color identification area 10. Operators place turnover boxes 5 filled with lychees on the conveyor line 1. On the conveyor line 1, the conveyor line 1 includes a lifting conveyor line 101, a roller conveyor line 102 and a receiving conveyor line 103 connected in sequence; the lifting conveyor line 101 includes a lifting belt 1011, and limit guard plates 1012 are provided on both sides of the lifting belt 1011; the turnover box 5 filled with lychees is placed on the lifting conveyor line 101 and is conveyed by the lifting conveyor line 101 to the roller conveyor line 102, conveyed from low to high. When the turnover box 5 passes the limit guard plate 1012, the limit guard plate 1012 can adjust the left and right position of the turnover box 5 so that when the turnover box 5 finally reaches the flipping component 2, it can be in the middle, so that the clamping rotating block 2016 can accurately clamp it.

[0052] The flipping component 2 flips the turnover box 5 in two steps, causing the lychees to spill out and slide onto the receiving conveyor line 3. The empty turnover box 5 is held by the empty box recycling component 3 and finally recycled by the recycling conveyor component 4. The lychees, after passing through the receiving conveyor line 103, are sent to the manual sorting area 6. The manual sorting area 6 includes a manual sorting conveyor belt 601, with manual sorting area guardrails 602 on both sides. Operators stand on both sides of the manual sorting area 6 to sort the lychees. While the lychees are being transported forward, the sorting staff remove any remaining branches, leaves, and damaged lychees from the pile. After passing through the manual sorting area 6, the lychees are sent to the size sorting area 7. After passing through the size sorting area 7, the larger lychees are sent to the large lychee color identification area 8, while the smaller lychees are sent to the small lychee color identification area 10. The large lychee color identification area 8 and the small lychee color identification area 10 will select the lychees based on their ripeness according to their color. Therefore, after passing through the automatic lychee sorting device, the lychees are sorted into different grades to facilitate the sale of the lychees by the vendors.

[0053] The flipping assembly 2 includes a first flipping mechanism 201 and a second flipping mechanism 202, which are hinged to the first flipping mechanism 201. The first flipping mechanism 201 clamps and causes the turnover box 5 to flip 90 degrees, and the second flipping mechanism 202 clamps and causes the turnover box 5 to continue to flip 90 degrees. After passing through the first flipping mechanism 201 and the second flipping mechanism 202, the turnover box 5 achieves a 180-degree flip. The first flipping mechanism 201 has clamping rotating blocks 2016 on both sides inside, which can move up, down, left, and right relative to the first flipping mechanism 201. The clamping rotating blocks 2016 on both sides of the first flipping mechanism 201 can move towards the center or separate to the sides. The empty box recycling assembly 3 is provided with a recycling rack 301, which includes a recycling ramp 3011. The second flipping mechanism 202 includes a flipping plate 2022, which can rotate to be directly above the recycling ramp 3011. Side clamping blocks 2024 are provided on both sides of the 022. The side clamping blocks 2024 on both sides of the flipping plate 2022 can move closer to the middle or separate to the sides. The flipping component 2 flips the turnover box 5 filled with lychees in two steps. First, the clamping rotating block 2024 clamps the turnover box 5 at both ends. Then, the clamping rotating block 2024 moves upward and towards the empty box recycling component 3. The clamping rotating block 2024 can rotate itself, so the turnover box 5 gradually flips 90 degrees due to gravity. At this time, the contents of the turnover box 5 are... The lychees will also be poured onto the conveyor line. Because the turnover box 5 is gradually tilted, the lychees gradually slide out of the turnover box 5. Finally, the turnover box 5 is pulled up, and the lychees are conveyed forward through the material passage formed between the recycling ramp 3011 and the receiving belt 1031. At this time, the turnover box has only rotated 90 degrees, and a small number of lychees are still left in the turnover box 5. Then, the second tilting mechanism 202 clamps the turnover box 5, and the tilting plate 2022 rotates to above the recycling ramp 3011. At this time, the turnover box has achieved a 180-degree rotation. All the branches are poured out, and the last lychee to fall slides from the recycling ramp 3011 onto the conveyor line 1. Since the turnover box 5 tilts to pour out the lychees instead of throwing them out in a feeding manner, the lychees will not be impacted by being thrown down during the entire flipping and unloading process, thus preventing damage to the lychees. The conveyor line 1 continuously transports the falling lychees away, so there is no accumulation of lychees, preventing them from being damaged by compression. Therefore, this automatic flipping and unloading device can effectively unload materials while ensuring the integrity of the lychees.

[0054] The roller conveyor line 102 is equipped with several first rollers 1021. The turnover boxes 5 must be fed into the flipping component 2 one by one. Therefore, when there are many turnover boxes 5 on the lifting conveyor line 101, the turnover boxes 5 can queue up on the roller conveyor line 102.

[0055] The receiving conveyor line 103 includes a receiving belt 1031, with receiving guard plates 1032 on both sides of the receiving belt 1031. A guard plate inlet ramp 10321 is located at the end of the receiving guard plate 1032 closest to the roller conveyor line 102. The flipping assembly 2 and the empty box recycling assembly 3 are located directly above the receiving conveyor line 103. A material passage is formed between the recycling ramp 3011 and the receiving belt 1031. Therefore, after the turnover box 5 is flipped, the lychees will fall onto the receiving belt 1031.

[0056] The first flipping mechanism 201 has flipping mounting side plates 2011 on both sides, and a first module 2012 is provided on the flipping mounting side plates 2011. The first slide rails 2013 are provided on both sides of the first module 2012. The first module 2012 and the first slide rails 2013 are slidably connected to the second module 2014. The second module 2014 is slidably connected to the first clamping cylinder 2015. The clamping rotating block 2016 is connected to the output end of the first clamping cylinder 2015. The clamping rotating block 2016 is provided with not less than one deformable particle 20161, which is made of compressible and deformable rubber material. The clamping rotating block 2016 clamps the turnover box 5 from both sides. The deformable particles 20161 are squeezed and deformed, increasing the clamping force of the clamping rotating block 2016 on the turnover box, so that the turnover box 5 will not fall off and hit the lychees on the receiving belt 1031. Under the action of the first module 2012 and the second module 2014, the clamping rotating block 2016 gradually moves towards the second flipping mechanism 202 and rises. Since the clamping rotating block 2016 can rotate, the turnover box 5 is subjected to gravity. The end of the turnover box 5 that is not clamped is at the bottom, while the clamped end gradually rises until finally the entire turnover box 5 is no longer in contact with the receiving belt 1031, and the lychees that are poured out can pass through the gap between the turnover box 5 and the receiving belt 1031.

[0057] The flip plate 2022 is connected to flip bearings 2021 at both ends, and second clamping cylinders 2023 are connected to both sides of the flip plate 2022. Side clamping blocks 2024 are connected to the output ends of the second clamping cylinders 2023, and the side clamping blocks 2024 are provided with clamping strips 20241. A starting flip connecting block 2029 is provided on the side of the flip plate 2022 away from the second clamping cylinders 2023. The starting flip connecting block 2029 is connected to a starting flip bearing 20291, and the starting flip bearing 20291 is connected to a flip connecting rod 2028. The flip connecting rod 2028 is connected to flip connecting fisheye connectors 2027 at both ends. The flip connecting fisheye connectors 2027 are connected to the output ends of the flip cylinder 2026. The tail end of the flip cylinder 2026 is rotatably connected to the flip cylinder seat 2025. The flip cylinder seat 2025 is connected to the flip mounting side plate 2011. Therefore, when the tilting cylinder 2026 retracts, the tilting plate 2022 and the receiving belt 1031 are in a perpendicular position. At this time, the turnover box 5 is pulled up by the clamping rotating block 2016 and positioned between the side clamping blocks 2024 on both sides. Under the drive of the second clamping cylinder 2023, the side clamping blocks 2024 clamp the turnover box 5. Under the drive of the first clamping cylinder 2015, the clamping rotating block 2016 retracts and moves back to the first tilting mechanism 201. At one end of the roller conveyor 102, the second box of lychees is clamped and flipped. Then, the flipping plate 2022 is flipped upward under the drive of the flipping cylinder 2026 until it is parallel to the receiving belt 1031. The side clamping block 2024 is provided with clamping strips 20241. The turnover box 5 has recessed positions on both sides. Therefore, the clamping strips 20241 can clamp the strip pillars on the frame of the turnover box 5, so that the turnover box 5 is not only clamped but also locked, making it difficult for the turnover box 5 to fall off.

[0058] A recycling rotating roller 3013 is provided at the end of the recycling rack 301 away from the recycling ramp 3011, and recycling ramp guard plates 3012 are provided on both sides of the recycling ramp 3011. A recycling movable clamp mounting tube 302 is provided above the recycling rack 301. A third module 303 and a second slide rail 304 are provided on the recycling movable clamp mounting tube 302. The third module 303 and the second slide rail 304 are movably connected to the recycling lifting cylinder 305. The recycling lifting cylinder 305 is connected to the recycling clamping cylinder 306. The recycling clamping cylinder 306 is connected to the recycling clamping plate 307. The two recycling clamps 307 on both sides of the recycling rack 301 clamp the turnover box 5 that has been flipped 180 degrees. The side clamp 2024 releases and no longer clamps the turnover box 5. The recycling clamps 307 clamp the turnover box 5 and pull it onto the recycling turning roller 3013 and put it down. The flipping plate 2022 flips downward under the drive of the flipping cylinder 2026 to restore the state perpendicular to the receiving conveyor line 103, and continues to clamp the next turnover box 5.

[0059] One end of the recycling rotating drum 3013 is connected to the recycling conveying assembly 4. After an empty turnover box 5 is placed on the recycling rotating drum 3013, the recycling rotating drum 3013 rotates under the drive of an external motor, conveying it towards the recycling conveying assembly 4. The recycling conveying assembly 4 includes a turning roller conveyor line 401 and a descending recycling conveyor line 402. Several recycling drums 4011 are provided on the turning roller conveyor line 401, and turning guard plates 4012 are provided on both sides of the recycling drums 4011. The descending recycling conveyor line 402 includes a descending recycling belt 4021, and descending guard plates 4022 are provided on both sides of the descending recycling belt 4021. The turnover box 5 is finally recycled by the recycling conveying assembly 4 for the next use. This unloading device is also equipped with turnover box 5 recycling. When loading and unloading, the turnover box 5 does not need to wait for the turnover boxes 5 in front and behind to leave before it can be operated, which conforms to the design concept of assembly line operation and improves work efficiency.

[0060] The large and small screening area 7 includes several screening shafts 701, and screening area guards 702 are provided on both sides of the screening shafts 701 to prevent lychees from falling from both sides of the large and small screening area 7. The small particle transport area 9 includes several small particle transport shafts 901, and small particle transport guards 902 are provided on both sides of the small particle transport shafts 901. The gap between two adjacent screening shafts 701 is larger than the gap between two adjacent small particle transport shafts 901. Therefore, when lychees pass through the large and small screening area 7, small lychees fall from the gap between two adjacent screening shafts 701 onto the small particle transport shafts 901, while large lychees pass through the large and small screening area 7 and are finally sent to the large particle color identification area 8. Small lychees are transported to the small particle color identification area 10 after passing through the small particle transport area 9.

[0061] The small particle transport guard plate 902 includes a receiving funnel 9021 and a small particle arc guard plate 9022. The receiving funnel 9021 is located directly below the size screening area 7. The receiving funnel 9021 includes a receiving straight edge 902A and a receiving inclined edge 902B. During the process of lychees falling from the gap between two adjacent screening shafts 701 onto the small particle transport shaft 901, the lychees on the side are not clamped by the receiving inclined edge 902B and the size screening area 7 due to the transition of the receiving straight edge 902A, thus preventing the lychees from getting stuck during the sorting process.

[0062] The large particle color discrimination area 8 includes at least one main channel 801 and at least one secondary channel 802, with the main channel 801 and secondary channel 802 arranged adjacent to each other. A visual recognition camera 803 is arranged above the main channel 801, and visual recognition auxiliary lights 804 are arranged around the visual recognition camera 803 to provide light for the visual recognition camera 803, enabling the visual recognition camera 803 to better identify lychees of different colors. A rotary cylinder 8 is arranged on the side of the visual recognition camera 803 away from the large and small sorting areas 7. 05. Rotary cylinder 805 is connected to screening and sorting channel 806. When lychees pass under visual recognition camera 803, visual recognition camera 803 quickly identifies the lychees. When lychees with poor color pass through screening and sorting channel 806, rotary cylinder 805 rotates, causing the outlet of screening and sorting channel 806 to swing to one side of the secondary channel, so that lychees with poor color are sorted into the secondary channel, thus finally completing the sorting of lychees. The structure of small particle color identification area 10 is the same as that of large particle color identification area 8, and will not be described in detail here.

[0063] This automatic lychee sorting device first sorts lychees by size, then further sorts large and small lychees by color. The large particle color sorting area and the small particle color sorting area can classify lychees of different ripeness and transport them separately.
