Description

Technical Field

[0001] This invention relates to the field of agricultural product processing technology, and in particular to an integrated machine for processing, sorting and cleaning bok choy. Background Technology

[0002] As a common leafy vegetable, bok choy's processing typically involves multiple stages, including sorting, washing, root cutting, and packaging. Currently, these stages mostly rely on manual labor or scattered mechanical equipment, resulting in low automation, low processing efficiency, and difficulty in standardizing hygiene. For example, in the sorting stage, manually removing yellow leaves is not only labor-intensive and inefficient, but also prone to inconsistent sorting standards due to visual fatigue or subjective judgment, affecting the quality of the finished product. In the washing stage, traditional soaking or simple spraying methods are insufficient to effectively remove impurities such as mud, sand, and insect eggs attached to leaf folds and roots, and washing water is often directly discharged, resulting in water waste. Furthermore, the processes of sorting, root cutting, washing, and packaging are poorly coordinated, requiring multiple material transfers, which not only increases the risk of breakage but also makes it difficult to achieve continuous and integrated processing. Therefore, designing an automated device that integrates sorting, washing, root cutting, and packaging functions, and achieves efficient, clean, and water-saving processing, has become a pressing technical problem to be solved to improve the quality and efficiency of bok choy processing.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 8This embodiment provides an integrated processing, sorting, and cleaning machine for bok choy, including a conveying assembly 1, a cleaning assembly 2, and a packaging assembly 3. The conveying assembly 1 includes a conveying group 11, a sorting group 12, and a root-cutting group 13. The conveying group 11 is used to convey bok choy. The sorting group 12 is located in the conveying direction of the conveying group 11 and is used to detect yellow leaves. The root-cutting group 13 is located in the conveying direction of the conveying group 11 and is adjacent to the sorting group 12. The root-cutting group 13 is used to cut off the roots of the bok choy. The cleaning assembly 2 is located at the output end of the conveying assembly 1 and includes a first cleaning group 21, a second cleaning group 22, a bubble group 23, and a filter group 24. The first cleaning group 21 and the second cleaning group 22 are arranged adjacent to each other, and the bubble group 23 is arranged in parallel with the first cleaning group 21. The first cleaning group 21 is used to clean the bok choy in the first round, the second cleaning group 22 is used to clean the bok choy in the second round, the bubble group 23 is used to clean the bok choy in the first round with bubbles, and the filter group 24 is used to filter and recycle the wastewater after cleaning. The packaging component 3 is set at the output end of the cleaning component 2. The packaging component 3 includes a first sealing group 31, a second sealing group 32 and a storage box 33. The first sealing group 31 and the second sealing group 32 are arranged adjacent to each other, and the storage box 33 is set at the output end of the second sealing group 32.

[0020] In this embodiment, the conveying group 11 in the conveying assembly 1 is responsible for conveying the bok choy forward in an orderly manner. Its specific structure may include a material plate or conveyor belt with guide grooves to ensure that the bok choy moves in a single file with its roots facing down. The sorting group 12 is set on the conveying path and is used to visually inspect the leaves of the bok choy to identify and remove individuals with defects such as yellow leaves. Preferably, this inspection can be performed by capturing images through a camera 121 and automatically judged by a control unit based on preset color and area thresholds. The root cutting group 13 is arranged adjacent to the sorting group 12 and is used to accurately cut the roots of the bok choy after sorting. Its execution component may be a rotating saw blade 132, and the bok choy is fixed by a structure such as a pressure plate 131 before cutting to ensure that the root is cut neatly.

[0021] The cleaning assembly 2 receives the bok choy processed by the conveying assembly 1 and performs a deep cleaning. The first cleaning group 21 performs a first round of spray cleaning on the bok choy, primarily removing surface-attached mud and larger impurities. The bubble group 23 works in parallel with the first cleaning group 21, generating numerous rising bubbles at the bottom of the water body. The impact force generated when these bubbles burst further removes stubborn dirt from leaf folds and rootstocks. Subsequently, the second cleaning group 22 performs a second round of spray cleaning on the bok choy. This cleaning uses an independent water source to ensure the final rinsing water is clean and avoids secondary pollution. The filtration group 24 filters the wastewater generated from the first round of cleaning, recovering relatively clean water resources, achieving water recycling, and reducing water consumption.

[0022] Packaging component 3 is located at the end of the washing process and is responsible for quantitatively packaging the cleaned bok choy. The first sealing group 31 performs horizontal heat sealing on the plastic film carrying the bok choy, forming a continuous packaging bag. The second sealing group 32 then performs vertical heat sealing and cutting on the continuous bag, thereby separating the bok choy into individual packaging units. Finally, the packaged products fall into the collection box 33 for collection.

[0023] When this device is in operation, the bok choy goes through a series of processes: conveying, automatic sorting of yellow leaves, mechanical root cutting, combined cleaning with bubble and two-stage spraying, and automatic heat sealing and packaging. The entire process does not require manual transfer of materials between processes, realizing assembly line operation.

[0024] This embodiment integrates sorting, root cutting, multi-mode cleaning, and packaging functions into a single device, constructing a complete automated processing line. This significantly improves the processing efficiency and hygiene standards of bok choy while reducing labor costs and intensity. Automated sorting of yellow leaves and precise root cutting ensure consistency in product appearance and specifications. Combined with bubble cleaning and secondary cleaning using an independent water source, impurities such as mud and insect eggs are effectively removed, improving cleanliness. Simultaneously, the wastewater filtration and recycling mechanism embodies a water-saving and environmentally friendly design concept. Finally, automated heat-sealing packaging not only facilitates storage and transportation but also extends the product's shelf life. The overall solution addresses the problems of poor process coordination, low efficiency, difficulty in ensuring hygiene, and water waste inherent in traditional decentralized processing methods.

[0025] In some embodiments, the cleaning assembly 2 further includes a cleaning chamber 25, a first conveyor belt 26, a conveyor wheel 27, a blower 28, and a filter plate 29. The cleaning chamber 25 contains a first cleaning group 21, a second cleaning group 22, and a bubble group 23. The bottom of the cleaning chamber 25 is inclined at a certain angle. The first conveyor belt 26 is disposed on one side of the cleaning chamber 25 and below the second cleaning group 22. Part of the first conveyor belt 26 is placed inside the cleaning chamber 25, and part of the first conveyor belt 26 protrudes out of the cleaning chamber 25 and extends outwards, with one end of the first conveyor belt 26 positioned above the packaging assembly 3. The conveyor wheel 27 is disposed inside the cleaning chamber 25. 27 is located at the connection between the first conveyor belt 26 and the washing box 25. The conveyor wheel 27 is provided with multiple first partitions 271. The first partitions 271 are used to transport the small green vegetables to the first conveyor belt 26 during the rotation of the conveyor wheel 27. The first partitions 271 actively cut into the water when rotating, pick up the small green vegetables from the washing liquid and move them. Its function is more focused on active transfer than static support. The blower 28 is located above the side of the first conveyor belt 26 that protrudes outward. The blower 28 is used to dry the small green vegetables. The filter mud plate 29 overlaps one side of the washing box 25 and is located at the end of the washing box 25 away from the first conveyor belt 26. The bottom of the filter mud plate 29 is provided with filter mud holes 291.

[0026] In this embodiment, the washing box 25 serves as a container for the washing function module, and its bottom is inclined at a certain angle. Specifically, this inclination angle can be designed to gradually decrease from the side closer to the first conveyor belt 26 to the side farther away from the first conveyor belt 26, so that heavy impurities such as mud and sand generated during the washing process can be deposited at lower levels under the action of gravity, facilitating subsequent centralized processing. The first conveyor belt 26 is used to scoop the washed bok choy from the washing box 25 and transport it to the packaging component 3. Part of its section is submerged in the water of the washing box 25, while another part extends upwards out of the box. Preferably, the surface of the first conveyor belt 26 is provided with multiple first partitions 261, which are spaced apart. Each pair of adjacent first partitions 261 can accommodate a single bok choy. These first partitions 261 can support and prevent the bok choy from sliding down during the inclined conveying process, forming an independent conveying unit. The surface of the first conveyor belt 26 can also be further provided with an anti-slip structure to prevent the bok choy from slipping during the conveying process.

[0027] A conveyor wheel 27 is positioned at the junction of the cleaning chamber 25 and the first conveyor belt 26. Multiple first partitions 271 distributed circumferentially on its surface, when rotating, can scoop up small green vegetables floating or submerged in the water one by one and transfer them onto the first conveyor belt 26, achieving a smooth transition from the cleaning medium to the conveyor belt. A blower 28 is installed above the extended section of the first conveyor belt 26 to blow airflow onto the small green vegetables on the conveyor belt, removing most of the moisture adhering to the leaf surface. A filter mud plate 29 overlaps the low-lying end of the inclined bottom of the cleaning chamber 25. Its bottom filter mud holes 291 allow water to flow through but intercept and collect deposited mud and sand, facilitating regular cleaning and maintaining the cleanliness of the water inside the chamber.

[0028] This embodiment constructs a highly efficient cleaning and material transfer system by setting up a cleaning tank 25 with an inclined bottom, in conjunction with conveyor wheels 27 and a first conveyor belt 26. After being cleaned by bubbles and sprays inside the tank, the bok choy is orderly picked up by the first partition 271 on the conveyor wheel 27 and transferred to the first conveyor belt 26. After being initially dried by the blower 28, it is sent to the packaging process. The inclined bottom of the tank guides the sediment to be deposited and filtered at the filter plate 29, effectively reducing the impurity content in the cleaning water and extending the usable cycle of the cleaning water. This structural design allows for close integration of the cleaning, draining, and conveying processes, which not only improves processing efficiency and ensures the cleanliness of the bok choy, but also reduces the frequency of manual cleaning and equipment maintenance costs through automatic sediment deposition and filtration, providing a reliable hardware foundation for continuous and automated bok choy processing.

[0029] In some embodiments, the first cleaning group 21 includes a first water storage tank 211, a first water pump 212, a first spray pipe 213, and a plurality of first nozzles 214. The first water pump 212 has a first pump inlet end, which is placed inside the first water storage tank 211. The first water pump 212 also has a first pump outlet end, which is placed inside the cleaning tank 25. The first spray pipe 213 is connected to the first pump outlet end and is distributed above the cleaning tank 25 in a first preset manner. The plurality of first nozzles 214 are disposed below the first spray pipe 213.

[0030] In this embodiment, the first water storage tank 211 is used to store cleaning water and can be connected to the filter group 24 to receive water after circulating filtration, realizing water resource reuse. The first water pump 212 is responsible for providing the power required for spraying. Its first pump inlet extends into the bottom of the first water storage tank 211 to draw water, and its first pump outlet delivers the pressurized water flow to the cleaning tank 25. The first spray pipe 213 is used to distribute the water flow above the cleaning area. It is distributed in a first preset manner, for example, multiple branch pipes can be arranged parallel to each other in the width direction of the cleaning tank 25 to ensure uniform spray coverage. Multiple first nozzles 214 are installed below the first spray pipe 213 to atomize the water flow or spray water jets at a specific angle onto the small green vegetables below for rinsing and cleaning. Preferably, the first nozzles 214 can be fan-shaped nozzles to expand the coverage area of ​​a single nozzle and improve cleaning efficiency.

[0031] In this embodiment, water is drawn from the first water storage tank 211 by the first water pump 212 and sprayed through the first spray pipe 213 and the first nozzle 214 to form a jet of water, which performs a first round of thorough rinsing on the bok choy located in the cleaning tank 25. This achieves directional and pressurized supply of cleaning water, ensuring cleaning intensity and uniform coverage. This embodiment provides a stable and efficient first cleaning process for bok choy processing, effectively removing most of the mud, sand, and loose impurities adhering to the surface of the bok choy. At the same time, by modularly integrating water storage, pumping, pipeline distribution, and spraying, the cleaning unit has a clear structure and is easy to maintain. It also lays a reliable foundation for coordinated work with subsequent bubble cleaning, secondary cleaning, and water circulation filtration systems, jointly ensuring the continuity and quality of the overall cleaning process.

[0032] In some embodiments, the filter assembly 24 includes a third water pump 241, a first water suction pipe 242, a first filter layer 243, a second filter layer 244, a third filter layer 245, and a second water suction pipe 246. The third water pump 241 is disposed inside the cleaning tank 25 and is located near the bottom of the cleaning tank 25. The first water suction pipe 242 is connected to the output end of the third water pump 241. The first filter layer 243 is connected to the other end of the first water suction pipe 242. The first filter layer 243 is filled with first filter media and has a plurality of first filter holes below it. The second filter layer 244 is disposed below the first filter layer 243. The second filter layer 244 is filled with second filter media and has a plurality of second filter holes below it. The third filter layer 245 is disposed below the second filter layer 244 and is filled with third filter media. The second water suction pipe 246 is connected to the third filter layer 245, and the other end of the second water suction pipe 246 is connected to the first water storage tank 211.

[0033] In this embodiment, the filter group 24 achieves multi-stage purification and recycling of cleaning wastewater. A third water pump 241, serving as a power source, is located at the bottom of the cleaning tank 25 and is used to extract the first round of cleaning wastewater containing mud and impurities. A first pumping pipe 242 transports the wastewater to the first filter layer 243, where the first filter media (such as coarse sand or pebbles) primarily intercepts larger suspended particles in the wastewater. After preliminary filtration by the first filter layer 243, the wastewater flows into the second filter layer 244 through the first filter holes below it. The second filter media (such as activated carbon or quartz sand) installed in the second filter layer 244 adsorbs finer impurities and removes some odors. Subsequently, the wastewater enters the third filter layer 245 through the second filter holes, where the third filter media (such as fine filter cotton or filter cloth) performs final fine filtration to remove fine particles. The purified water flows back to the first water storage tank 211 via the second pumping pipe 246 for reuse by the first cleaning group 21. Preferably, each filter layer has a detachable modular structure, which facilitates regular cleaning or replacement of the filter media to maintain filtration efficiency.

[0034] This embodiment employs a three-stage filtration system to perform progressively finer filtration of the cleaning wastewater. A third pump 241 pumps the wastewater from the bottom of the cleaning tank 25, allowing it to flow sequentially through the first filter layer 243, the second filter layer 244, and the third filter layer 245, each containing different filter media. Impurities are progressively removed, resulting in relatively clean water that is then returned to the first water storage tank 211. This embodiment constructs a highly efficient and sustainable water circulation system, significantly reducing the consumption of fresh water and aligning with water-saving and environmentally friendly production principles. The multi-stage filtration design ensures the cleanliness of the recycled water, meeting the water requirements for the first round of cleaning and preventing secondary pollution or reduced cleaning effectiveness due to water quality issues. Furthermore, the filtration system has a clear structure, is easy to maintain, ensures the long-term stable operation of the cleaning component 2, and reduces overall operating costs.

[0035] In some embodiments, the second cleaning group 22 includes a second water storage tank 221, a second water pump 222, a second spray pipe 223, and a plurality of second nozzles 224. The second water pump 222 has a second pump inlet end, which is placed inside the second water storage tank 221. The second water pump 222 also has a second pump outlet end, which is placed inside the cleaning tank 25. The second spray pipe 223 is connected to the second pump outlet end and is distributed above the cleaning tank 25 in a second preset manner. The second spray pipe 223 is disposed above the first conveyor belt 26, and the inclination angle of the second spray pipe 223 is the same as the inclination angle of the first conveyor belt 26. The plurality of second nozzles 224 are disposed below the second spray pipe 223.

[0036] In this embodiment, the second washing group 22 is responsible for the final round of cleaning spraying on the bok choy. The second water storage tank 221 stores clean washing water, with an independent water source, such as direct access to tap water or a separate purified water tank, to ensure physical isolation from the first round of washing water and avoid cross-contamination. The second water pump 222 pumps clean water from the second water storage tank 221 and delivers it through the second spray pipe 223. The second spray pipe 223 is positioned above the first conveyor belt 26, and its second preset distribution is designed to cover the effective width of the conveyor belt. It is important to note that the inclination angle of the second spray pipe 223 is consistent with the inclination angle of the first conveyor belt 26, so that the direction of the water flow from the second nozzles 224 can better match the conveying trajectory and posture of the bok choy on the conveyor belt, achieving more precise and efficient rinsing. Multiple second nozzles 224 spray downwards, performing a final rinse on the bok choy moving on the first conveyor belt 26.

[0037] In this embodiment, the second cleaning group 22 utilizes an independent clean water source to perform top-down directional spray rinsing on the bok choy as it is scooped up by the first conveyor belt 26 and transported out of the cleaning box 25. Because the second spray pipe 223 is tilted at the same angle as the first conveyor belt 26, the water flow continuously and directly washes the surface of the bok choy, effectively removing any residual impurities or suspended matter that may have been carried after the first round of cleaning and bubble cleaning. This embodiment provides a crucial final cleaning guarantee, ensuring the final cleanliness of the bok choy when it leaves the cleaning area and avoiding the risk of secondary contamination caused by sharing the cleaning water. This independent water source and trajectory-matched spray design not only ensures the cleaning effect but also optimizes water usage efficiency, providing reliable technical support for achieving high-quality, hygienic automated processing of bok choy.

[0038] In some embodiments, the bubble assembly 23 includes an air pump 231, a main air supply pipe 232, a plurality of air supply branch pipes 233, and a plurality of air supply nozzles 234. The main air supply pipe 232 is connected to the output end of the air pump 231. The plurality of air supply branch pipes 233 are disposed inside the cleaning chamber 25 and are located near the bottom of the cleaning chamber 25. Each air supply branch pipe 233 is individually connected to the main air supply pipe 232, and the plurality of air supply branch pipes 233 are arranged at intervals. The plurality of air supply nozzles 234 are disposed on the air supply branch pipes 233 and are used to spray out bubbles.

[0039] In this embodiment, the bubble array 23 is used to generate a large number of rising bubbles in the water of the cleaning tank 25 to assist in cleaning. An air pump 231 serves as the air source, supplying air to multiple air branch pipes 233 through the main air pipe 232. The air branch pipes 233 are laid parallel and spaced apart at the bottom of the cleaning tank 25 to increase the bubble coverage area. Each air branch pipe 233 is provided with multiple air nozzles 234 for dispersing air into fine bubbles and releasing them into the water. Preferably, the air nozzles 234 can be designed with a microporous structure to generate a denser and more uniform bubble flow.

[0040] It should be noted that the "parallel arrangement" of the bubble group 23 and the first cleaning group 21 refers to their juxtaposition in terms of spatial layout and functional synergy within the cleaning chamber 25. Specifically, the ventilation branch pipe 233 of the bubble group 23 is laid at the bottom of the cleaning chamber 25, while the first spray pipe 213 and the first nozzle 214 of the first cleaning group 21 are located above the cleaning chamber 25. They are vertically offset but partially overlap in horizontal projection, working together to clean the same area. During the actual cleaning process, while the first cleaning group 21 sprays and rinses, the bubble group 23 generates rising bubbles to assist in agitating the water flow and removing dirt. The two work simultaneously and complement each other, jointly constituting the first round of deep cleaning for the bok choy.

[0041] In this embodiment, air generated by the air pump 231 is transported through pipelines and released from the vent 234 at the bottom of the cleaning chamber 25, forming a continuously rising stream of bubbles. These bubbles burst as they rise, and the resulting physical impact effectively disturbs the water flow, removing stubborn dirt and sand adhering to the folds of the bok choy leaves and the stems. This bubble cleaning method, as a supplement to spray cleaning, significantly improves the cleaning effect, especially in removing stains from hidden areas that are difficult to reach with mechanical rinsing, thereby improving the overall cleanliness of the bok choy.

[0042] In some embodiments, the conveying assembly 11 includes a conveying plate 111, a guide plate 112, a lever 113, a first drive unit 114, a second conveyor belt 115, a side baffle 117, a bottom baffle 118, and a conveying hopper 119. The conveying plate 111 includes at least one row of conveying troughs for placing bok choy. The guide plate 112 includes at least one guide trough, which is connected to one end of the conveying trough. The lever 113 is disposed at the connection between the conveying plate 111 and the guide plate 112, and part of the lever 113 is embedded in the channel formed by the connection between the guide trough and the conveying trough to actuate a single bok choy. The first drive unit 114 is driven by the lever 113 to drive the lever 113 to actuate the bok choy. The second conveyor belt... The second conveyor belt 115 is vertically arranged, and multiple second partitions 116 are equidistantly arranged on the outer side of the second conveyor belt 115. The spacing between two adjacent second partitions 116 is adapted to the size of the guide trough. The side baffle 117 is arranged on the side of the second conveyor belt 115 and on the side where the guide trough is located. The side baffle 117 is made of transparent material. The bottom baffle 118 is arranged at the bottom of the second conveyor belt 115 and on the side where the guide trough is located. The bottom baffle 118 has an opening groove in the middle for the roots of the bok choy to protrude to the outside. The conveying hopper 119 is arranged at one end of the second conveyor belt 115 and at the end of the second conveyor belt 115 away from the guide plate 112. The conveying hopper 119 is positioned above the washing assembly 2.

[0043] In this embodiment, the conveying group 11 realizes the orderly and individual conveying of bok choy from feeding to before it enters the washing component 2. The conveying trough on the conveying plate 111 is used to initially sort and orient the rows of bok choy, and its trough structure ensures that the roots of the bok choy are facing downwards. The guide trough on the guide plate 112 is connected to the conveying trough, playing a transitional and further guiding role. The lever 113 swings periodically under the drive of the first drive unit 114, and part of its rod is embedded in the channel formed by the connection of the conveying trough and the guide trough, thereby pulling the bok choy from the conveying trough into the guide trough one by one at intervals, realizing the conversion from continuous discharge to intermittent single-plant feeding. The second conveyor belt 115 is set vertically, and multiple second partitions 116 fixed at equal intervals on its outer side correspond to the outlet of the guide trough, and each second partition 116 forms an independent space to accommodate a single bok choy. Side baffles 117, made of transparent material (such as acrylic), are located on the side of the second conveyor belt 115 near the guide plate 112. This prevents the bok choy from falling sideways without obstructing the visual inspection of the subsequent sorting group 12. Bottom baffles 118 are also located on this side, with an opening in the middle allowing excessively long roots of the bok choy to extend downwards, providing support for the main body while reserving operating space for the subsequent root-cutting process. The conveying hopper 119 receives the bok choy from the top of the second conveyor belt 115 and guides it to the washing assembly 2 below.

[0044] This embodiment utilizes the synergistic action of the conveyor trough, lever 113, second conveyor belt 115, and its partitions to organize scattered or rowed bok choy into neat, upright individual plants with exposed roots, conveyed continuously at a constant pace. Lever 113 enables precise separation of individual plants, the second conveyor belt 115 and its partitions ensure individual separation and posture stability during transport, the transparent side baffles 117 facilitate visual inspection, and the opening slots in the bottom baffle 118 prepare for root processing. This embodiment provides a stable and reliable material flow for subsequent automated sorting and root cutting processes, serving as a crucial front-end step for efficient and automated bok choy processing. It effectively avoids material congestion and posture disorder, ensuring smooth operation of the entire production line and consistent processing quality.

[0045] In some embodiments, the root-cutting assembly 13 includes a pressure plate 131, a saw blade 132, and a second drive unit 133. The pressure plate 131 is positioned at a first preset height, which is configured to be the height of the rootstock of the bok choy near its root when it is placed in the second conveyor belt 115. Part of the pressure plate 131 is embedded between the side baffle 117 and the bottom baffle 118 and is placed in the second conveyor belt 115 to compact the bok choy. The saw blade 132 is positioned below the bottom baffle 118 and below the opening slot, and is used to cut off the root of the bok choy. The second drive unit 133 is connected to the saw blade 132 in a transmission manner.

[0046] In this embodiment, the root-cutting assembly 13 is used for automated cutting of the roots of bok choy. A pressure plate 131 is positioned at a specific height, corresponding to the approximate position of the rootstock (i.e., the connection between the root and the main body) of the bok choy when it is conveyed between the partitions of the second conveyor belt 115. Part of the pressure plate 131 extends into the space between the side baffle 117 and the bottom baffle 118. When the bok choy moves to this station with the second conveyor belt 115, the pressure plate 131 presses down on the rootstock from the side, temporarily fixing it and preventing the plant from shaking during cutting. The saw blade 132 is located directly below the opening slot of the bottom baffle 118, with its plane of rotation perpendicular to the conveying direction. A second drive unit 133 (such as a motor) drives the saw blade 132 to rotate at high speed. When the bok choy root, fixed by the pressure plate 131, hangs down from the opening slot and passes over the saw blade 132, the rotating saw blade 132 cuts off the root. Preferably, the surface of the pressure plate 131 may be covered with an elastic material (such as foam) to avoid damaging the vegetable leaves while compacting.

[0047] In this embodiment, when the bok choy is conveyed to the root-cutting station by the second conveyor belt 115, its roots hang down through the opening slot of the bottom baffle 118. The pressure plate 131 first compacts the rootstock to stabilize the plant, and then the high-speed rotating saw blade 132 neatly cuts off the hanging roots, realizing the automation and precision of the root-cutting process. The fixed pressure plate 131 ensures that the bok choy does not shift during cutting, ensuring a flat cut; the saw blade 132 cuts from below, so that the cutting action matches the natural hanging state of the cut part (root), making the operation efficient and safe. This root-cutting group 13 works closely with the aforementioned conveyor group 11 to quickly complete the root-cutting operation during continuous conveying, significantly improving processing efficiency and product consistency, and providing uniform raw materials for subsequent cleaning and packaging.

[0048] In some embodiments, the sorting group 12 includes a camera 121, a control unit, a movable baffle 122, a third drive unit 123, and a defect collection box 124. The acquisition end of the camera 121 is set facing the side baffle 117 to collect leaf information of the bok choy. The control unit is electrically connected to the camera 121 and is used to determine whether the bok choy has defects based on the leaf information. The movable baffle 122 is set in the extension direction of the bottom baffle 118, and the bottom baffle 118 is not connected to the movable baffle 122. The third drive unit 123 is driven to the movable baffle 122 and is also electrically connected to the control unit. The third drive unit 123 is used to drive the movable baffle 122 to move away from the extension direction of the bottom baffle 118 so that the bok choy with defects falls down. The defect collection box 124 is set below the second conveyor belt 115 and in the area where the movable baffle 122 is located. The defect collection box 124 is used to collect the fallen bok choy with defects.

[0049] In this embodiment, the sorting group 12 uses machine vision to automatically detect and remove defects such as yellow leaves from bok choy. A camera 121 is positioned facing the transparent side baffle 117 to obtain clear images of the bok choy leaves on the second conveyor belt 115. The control unit receives the image information and analyzes the presence of defects such as yellowing on the leaves using image processing algorithms (e.g., threshold judgment based on color and area). A movable baffle 122 is positioned at the end of the bottom baffle 118, but is separate and independent from it. When the control unit determines that the bok choy at the current station has defects, it sends a command to the third drive unit 123 (e.g., a stepper motor). The third drive unit 123 drives the movable baffle 122 to open rapidly to one side (away from the direction of the bottom baffle 118), causing the bok choy to lose its bottom support and fall from between the second partitions 116 of the second conveyor belt 115. A defect collection box 124 is located below this area to receive and collect the rejected defective bok choy. Preferably, the judgment logic of the control unit can be set to trigger rejection when either the area threshold or the number of color blocks is met, and the threshold can be adjusted to adapt to different quality requirements.

[0050] In this embodiment, when the bok choy moves to the inspection station along the second conveyor belt 115, the camera 121 captures images through the side baffle 117, and the control unit analyzes and judges them in real time. If it is identified as a defective product, the movable baffle 122 is opened instantly, causing the defective bok choy to fall into the defect collection box 124 below; if there are no defects, the movable baffle 122 remains closed, and the bok choy continues to be conveyed to the next process. This embodiment realizes the automation and intelligence of yellow leaf sorting, replacing the traditional inefficient manual selection. The vision-based detection method is objective and accurate, and the configurable threshold improves the sorting flexibility. The sorting action is fast and accurate, and synchronized with the conveying rhythm, effectively improving the overall quality of raw materials and the value of subsequent processing without affecting the continuous conveying of qualified products.

[0051] In some embodiments, the packaging assembly 3 further includes a frame 34, a support plate 35, and a plastic roller 36. A first sealing assembly 31 and a second sealing assembly 32 are disposed on the frame 34 along the conveying direction of the bok choy. The support plate 35 is disposed on the frame 34, and its input end is provided with a first extension plate 351 and a second extension plate 352 disposed opposite to each other. The output end of the washing assembly 2 is located above the input end of the support plate 35. The plastic roller 36 is covered with multiple layers of plastic and is disposed on the frame 34, below the input end of the support plate 35. The plastic extends upwards and is laid flat on the first extension plate 351 and the second extension plate. 352; The first molding assembly 31 is disposed above the support plate 35. The first molding assembly 31 includes a fourth drive unit 311, a first guide main roller, a first guide slave roller, a second guide main roller, a second guide slave roller, and a first heater 312. The first guide main roller is drivenly connected to the fourth drive unit 311; the first guide slave roller is drivenly connected to the first guide main roller, and there is a first preset gap between the first guide slave roller and the first guide main roller. The first preset gap is configured to correspond to the adhesive gap of the plastic; the second guide main roller is drivenly connected to the first guide main roller, and the second guide main roller is drivenly connected to the first guide main roller. The rollers are spaced apart along the conveying direction of the bok choy; the second guide roller is positioned opposite the second guide main roller, and is drively connected to the first guide roller, with a second preset gap between them, configured to correspond to the adhesive seam of the plastic; a first heater 312 is located in the middle of the first and second guide rollers, and has a first heat-sealing groove inside, corresponding to the adhesive seam of the plastic, and is used to heat-seal the plastic along a first direction a; a second sealing assembly 32 is located at the output end of the support plate 35. The storage box 33 is located on the side of the second sealing assembly 32 away from the support plate 35. The second sealing assembly 32 includes a fifth drive unit 321, a sixth drive unit 322, a second heater 323, and a third heater 324. The sixth drive unit 322 and the fifth drive unit 321 are arranged at intervals along the vertical direction. The second heater 323 has a first heat-sealing serration and is drivenly connected to the fifth drive unit 321. The third heater 324 has a second heat-sealing serration and is drivenly connected to the sixth drive unit 322. When the first heat-sealing serration and the second heat-sealing serration are engaged, the plastic can be heat-sealed along the second direction b.

[0052] In this embodiment, the packaging component 3 automatically wraps, seals, and cuts the bok choy. The frame 34 serves as a support structure, and the support plate 35 carries the delivered bok choy. The first extension plate 351 and the second extension plate 352 on both sides of the input end guide and flatten the packaging plastic film extending from the plastic roller 36. After being output from the washing component 2, the bok choy falls onto the center of the plastic film laid flat on the support plate 35 and is conveyed along the first direction a with the film.

[0053] The first sealing assembly 31 is used to heat-seal both edges of the plastic film along the first direction a to form a tubular bag for wrapping the bok choy. The first sealing assembly 31 has two pairs of guide rollers spaced apart along the first direction a: a first main guide roller and a first secondary guide roller form one pair, and a second main guide roller and a second secondary guide roller form the other pair. Each pair of main and secondary guide rollers has a preset gap (a first preset gap and a second preset gap, respectively).

[0054] The principle of plastic film feeding and sealing can be understood as follows: the flat plastic film and the small green vegetables it carries are conveyed together along the first direction a; the two sides of the plastic film extending along the first direction a are respectively guided and clamped into the first preset gap between the first pair of rollers and the second preset gap between the second pair of rollers; the width of the first preset gap and the second preset gap are precisely set so that the edge area of ​​the plastic film can be tightly clamped and guided in a double-layer overlapping form, preparing for subsequent heat sealing; the fourth drive unit 311 drives the first guide main roller to rotate, and drives the second guide main roller to rotate synchronously through the transmission mechanism, thereby pulling the clamped edge of the plastic film to move forward smoothly along the first direction a.

[0055] The first heater 312 is fixedly disposed within the space between the two pairs of guide rollers. The first heater 312 has a first heat-sealing groove extending along the first direction a. When the two edges of the plastic film, held and pulled forward by the two pairs of rollers, pass through the first heater 312, the first heat-sealing groove continuously heats the two clamped double-layer edge areas, causing the upper and lower layers of the plastic film to fuse and bond together, thus completing the transverse sealing along the first direction a during travel. Through this process, the flat plastic film is transformed into a continuous tubular package with sealed sides, enclosing the small green vegetables. Subsequently, the tubular package with the transverse sealing completed is continued to be conveyed along the first direction a, entering the station of the second sealing group 32.

[0056] In this embodiment, the bok choy falls onto a plastic film laid flat on the support plate 35 and moves forward with the film. The first sealing group 31 first uses heaters to continuously heat-seal both edges of the film laterally, wrapping the bok choy inside the sealed tubular film. Subsequently, the two serrated heaters of the second sealing group 32 periodically engage to perform longitudinal heat-seal on the film between adjacent bok choy and simultaneously cut it, achieving quantitative packaging. This embodiment realizes a fully automated packaging process from film conveying, wrapping, lateral sealing to longitudinal cutting. The packaging process is continuous and efficient, and the heat seal is firm and reliable, effectively isolating external contamination and extending the shelf life of the bok choy. Automated quantitative packaging facilitates storage, transportation, and sales, improves the commercialization of the product, and completes the final automated processing step from raw bok choy to retail packaged finished product.

[0057] By adopting the above technical solutions, this invention differs from existing technologies and has the following beneficial effects: By integrating conveying, sorting, root cutting, multi-mode cleaning, and packaging functions into one device, a complete automated processing line is constructed. This device uses the conveyor group 11 to arrange the bok choy into single, upright plants, and the sorting group 12 automatically identifies and removes defective products such as yellow leaves based on machine vision. Then, the root cutting group 13 precisely cuts off the roots, achieving automated pre-processing of the raw materials. The cleaning process uses a combination of spraying by the first cleaning group 21, auxiliary spraying by the bubble group 23, and independent rinsing by the second cleaning group 22, along with a cleaning tank 25 with an inclined bottom and a multi-stage filtration wastewater recovery system. This efficiently removes impurities such as mud, sand, and insect eggs while significantly saving water resources. In the packaging process, the first sealing group 31 heat-seals the plastic film along both sides of the first direction a to form a tubular package, and then the second sealing group 32 seals and cuts it along the second direction b to form individual packages. The above-mentioned technical solution realizes continuous and automated operation from feeding small green vegetables to packaging finished products, effectively solving the problems of poor process connection, low efficiency, difficulty in unifying hygiene standards and water waste in traditional decentralized processing, greatly improving processing efficiency, product cleanliness and consistency, and reducing labor costs and labor intensity.
