Description

Technical Field

[0001] This invention belongs to the technical field of vegetable cleaning equipment, and in particular relates to an automated device and working method for cleaning multiple types of vegetables. Background Technology

[0002] With the rapid development of industrialized catering, standardized pre-prepared vegetables, and large-scale pre-cooked meals, the pre-processing of fresh vegetables has shifted from scattered manual operations to continuous, automated assembly line production. In actual production, upstream workers first need to perform preliminary pre-processing on leafy vegetables, root vegetables, and fruit vegetables, such as removing old leaves, roots, and stems. Then, the three types of vegetables are mixed and transported to the washing section for cleaning through methods such as spraying and bubble washing.

[0003] For example, the patented circulating water bubble cleaning machine proposed in CN222366997U uses a cleaning tank with a lifting conveyor belt, a top soft brush roller and a circulating water structure. The lifting of the conveyor belt facilitates the cleaning of debris at the bottom of the tank, and the soft brush and bubbles work together to complete the cleaning.

[0004] The above-mentioned patent has the following defects in use:

[0005] First, the lack of an industrial camera-based intelligent recognition and automatic sorting mechanism makes it impossible to automatically identify and separate pre-processed mixed vegetables, requiring manual sorting and feeding, resulting in a low level of automation. Second, the single washing tank means that leafy vegetables, root vegetables, and fruits can only be washed together, without separate tanks for isolated washing, thus failing to solve the problem of cross-contamination. Third, the washing mode is singular and fixed, using only a general washing method of soft brushes and bubbles, which cannot differentiate between gentle washing, strong washing, and general washing based on the characteristics of the three types of vegetables. The damage rate of ingredients and the cleanliness of the washing cannot meet production requirements. Therefore, this invention proposes an automated equipment and working method for multi-vegetable classification and washing. Summary of the Invention

[0006] This invention provides an automated device and method for classifying and cleaning multiple types of vegetables. Through the coordinated operation of an electric telescopic rod, camera gimbal, and recognition camera in the classification mechanism, the recognition angle can be flexibly adjusted to perform real-time, accurate image acquisition and category identification of the pre-processed, mixed-conveyed vegetables. Simultaneously, with the assistance of a servo motor and flexible classification baffles, the vegetables are automatically guided to preset outlets and slid into corresponding dedicated cleaning tanks via inclined guide plates, achieving automatic classification and significantly reducing manual intervention. The device utilizes a feeding and conveying component in conjunction with cleaning tanks for leafy vegetables, fruits, and root vegetables, with each tank equipped with an independent circulating spray machine. The structure provides completely independent and dedicated cleaning spaces for three different types of vegetables, achieving physical isolation cleaning of leafy vegetables, fruits, and root vegetables to avoid cross-contamination. Through the cooperation of the first, second, and third cleaning mechanisms, and based on the physical characteristics of leafy vegetables, fruits, and root vegetables, it matches dedicated cleaning modes for each type: gentle non-contact bubble cleaning, general cleaning with soft brushes, and powerful cleaning with alternating scrubbing with hard brushes. This ensures that leafy vegetables are not damaged, fruits are not scratched, and root vegetables are effectively cleaned, balancing the integrity of the ingredients with the cleanliness of the cleaning process, thus solving the problems in the background technology.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0019] Furthermore, the rotation direction of the first wear-resistant nylon bristle brush roller is opposite to the conveying direction of the root and tuber cleaning and conveying assembly, while the rotation direction of the second wear-resistant nylon bristle brush roller is the same as the conveying direction of the root and tuber cleaning and conveying assembly.

[0020] A method for operating an automated equipment for sorting and cleaning multiple types of vegetables includes the following steps:

[0021] S1: Feeding and Identification: Pre-treated leafy vegetables, melons, fruits, and root vegetables are mixed and placed on the feeding and conveying assembly; during the conveying process, the vegetables pass under the identification and classification mechanism, where the identification camera captures images and identifies the types of vegetables.

[0022] S2: Automatic sorting: The main controller controls the corresponding first servo motor to rotate the flexible sorting baffle based on the recognition result.

[0023] S2a: If the vegetable is identified as a leafy vegetable, the flexible sorting baffle remains in the retracted state, and the vegetable slides into the leafy vegetable washing tank along the end of the feeding conveyor assembly via the first inclined guide plate.

[0024] S2b: If the food is identified as a fruit or root vegetable, the corresponding flexible sorting baffle rotates downward to guide the food from the corresponding side outlet through the second inclined guide plate into the fruit or root vegetable washing tank.

[0025] S3: Differentiated Cleaning

[0026] S3a: Vegetables entering the leafy vegetable washing tank are carried and conveyed by the leafy vegetable washing and conveying component; the first washing mechanism is activated, the fan supplies air through the air pipe, and the air bubbles generated by the aeration head gently tumble and wash the vegetables; at the same time, the circulating spray mechanism of the tank works, and the filtered water is sprayed and rinsed on the vegetables through the first spray head.

[0027] S3b: Vegetables entering the fruit and vegetable washing tank are carried and conveyed by the fruit and vegetable washing and conveying component; the second washing mechanism is started, and the second servo motor drives a pair of soft nylon brush rollers to rotate, gently brushing the surface of the vegetables; at the same time, the circulating spray mechanism of the tank works, spraying filtered water onto the vegetables through the second nozzle.

[0028] S3c: Vegetables entering the root and stem cleaning tank are carried and conveyed by the root and stem cleaning conveying component; the third cleaning mechanism is activated, and the third servo motor drives the first wear-resistant nylon hard bristle brush roller to rotate in the opposite direction, and drives the second wear-resistant nylon hard bristle brush roller to rotate in the forward direction through gears, so as to perform strong friction and scrubbing on the vegetables; at the same time, the circulating spray mechanism of the tank works, and the filtered water is sprayed and rinsed on the vegetables under high pressure through the third nozzle;

[0029] S4: Water circulation: Wastewater generated during the cleaning process in each cleaning tank is pumped into the corresponding filter box through its own pumping pipe. After being filtered and purified by the removable filter screen and the removable activated carbon filter layer, it is pumped back by the circulation pump body to form an independent internal circulation.

[0030] S5: Discharge: The cleaned vegetables are conveyed out of their respective cleaning tanks by the leafy vegetable cleaning conveyor, melon and fruit cleaning conveyor, and root vegetable cleaning conveyor, completing the sorting and cleaning operation.

[0031] The present invention has the following advantages over the prior art:

[0032] (1) Intelligent recognition and automatic classification: This technical solution uses the cooperation of electric telescopic rod, camera gimbal and recognition camera in the recognition and classification mechanism to flexibly adjust the recognition angle and perform real-time and accurate image acquisition and classification of the pre-processed mixed conveyed dishes. At the same time, with the help of servo motor and flexible classification baffle, the dishes are automatically guided to the preset outlet and slid into the corresponding special cleaning tank through the inclined guide plate to achieve automatic classification and greatly reduce the degree of manual intervention.

[0033] (2) Separate tanks to prevent contamination: This technical solution uses the feeding and conveying components to cooperate with the leafy vegetable washing tank, the melon and fruit washing tank and the root and stem washing tank. At the same time, each washing tank is equipped with an independent circulating spraying mechanism, which sets up a completely independent exclusive washing space for the three different types of vegetables. This achieves physical isolation washing of leafy vegetables, melons and fruits and root and stem vegetables, avoiding cross-infection problems.

[0034] (3) Differentiated cleaning, protecting vegetables and cleaning: This technical solution, through the cooperation of the first cleaning mechanism, the second cleaning mechanism and the third cleaning mechanism, matches the physical characteristics of leafy vegetables, melons and fruits and root vegetables with exclusive cleaning modes respectively, including non-contact bubble gentle cleaning, soft brush gentle brush general cleaning, and hard brush alternating scrubbing strong cleaning. This ensures that leafy vegetables are not damaged, melons and fruits are not scratched, and root vegetables are efficiently removed from mud and sand, taking into account both the integrity rate of ingredients and the cleanliness of cleaning.

[0035] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0053] 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.

[0054] In the description of this invention, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention. Specific Implementation Example 1:

[0056] Please see Figures 1-14 As shown, the present invention provides an automated device and method for classifying and cleaning multiple types of vegetables, comprising:

[0057] The feeding and conveying assembly 1, leafy vegetable washing tank 3, melon and fruit washing tank 4, root and stem vegetable washing tank 5, leafy vegetable washing and conveying assembly 6, melon and fruit washing and conveying assembly 7, and root and stem vegetable washing and conveying assembly 8 are provided. Leafy vegetable washing tank 3, melon and fruit washing tank 4, and root and stem vegetable washing tank 5 are all located outside the feeding and conveying assembly 1, while leafy vegetable washing and conveying assembly 6, melon and fruit washing and conveying assembly 7, and root and stem vegetable washing and conveying assembly 8 are respectively installed inside leafy vegetable washing tank 3, melon and fruit washing tank 4, and root and stem vegetable washing tank 5.

[0058] The identification and classification mechanism 9 is used for identifying the types of vegetables. The identification and classification mechanism 9 includes an electric telescopic rod 901, a camera gimbal 902 and an identification camera 903. A U-shaped plate 2 is fixedly connected to the outer wall of the feeding and conveying assembly 1. The electric telescopic rod 901 is installed on the inner top of the U-shaped plate 2. The identification camera 903 is installed on the camera gimbal 902. The output end of the electric telescopic rod 901 is connected to the top of the camera gimbal 902.

[0059] Three circulating spraying mechanisms 10 are respectively installed on the leafy vegetable washing tank 3, the melon and fruit washing tank 4, and the root and stem vegetable washing tank 5. The three circulating spraying mechanisms 10 are used for filtering, circulating and spraying the water inside the leafy vegetable washing tank 3, the melon and fruit washing tank 4, and the root and stem vegetable washing tank 5. Each of the three circulating spraying mechanisms 10 includes a circulating pump body 1001, a filter box 1002 and a water pumping pipe 1004. The three water pumping pipes 1004 are respectively fixedly connected to the side walls of the leafy vegetable washing tank 3, the melon and fruit washing tank 4, and the root and stem vegetable washing tank 5, and the other end of the water pumping pipe 1004 is connected to the side wall of the filter box 1002. A suction pipe 1007 is fixedly connected between the suction end of the circulating pump body 1001 and the side wall of the filter box 1002.

[0060] The three cleaning mechanisms are: a first cleaning mechanism 12, a second cleaning mechanism 14, and a third cleaning mechanism 16. The first cleaning mechanism 12 includes a fan 1201, an air duct 1202, and multiple aeration heads 1203, and is used for cleaning leafy vegetables. The second cleaning mechanism 14 includes a pair of soft nylon brush rollers 1401, and is used for cleaning melons and fruits. The third cleaning mechanism 16 includes three first wear-resistant nylon hard brush rollers 1601 and two second wear-resistant nylon hard brush rollers 1602, which are arranged alternately along the conveying direction of the root and stem vegetable cleaning and conveying assembly 8. The third cleaning mechanism 16 is used for cleaning root and stem vegetables.

[0061] In the specific implementation process, the feeding and conveying component 1 realizes the continuous feeding of the pre-treated mixed vegetables. Simultaneously, three physically independent washing tanks 3 for leafy vegetables, 4 for melons and fruits, and 5 for root vegetables are set up, each corresponding to a dedicated washing space for the three types of vegetables. The leafy vegetable washing and conveying component 6, the melon and fruit washing and conveying component 7, and the root vegetable washing and conveying component 8 are responsible for receiving the diverted vegetables and completing the conveying and washing operations in the tanks, realizing a completely isolated layout of "one type, one tank, one conveyor".

[0062] It is worth noting that in this embodiment, the feeding and conveying component 1 is a food-grade flat belt conveyor, which adopts a non-perforated, sealed food-grade PU flat belt. The core consists of a drive motor, a drive roller, a driven roller, a food-grade PU flat belt, and a 304 stainless steel frame. The drive motor drives the drive roller to rotate, thereby driving the flat belt to run at a uniform speed, realizing the stable conveying of the pre-treated mixed vegetables without material falling or water leakage. The leafy vegetable washing and conveying component 6, the melon and fruit washing and conveying component 7, and the root and stem vegetable washing and conveying component 8 are all food-grade mesh belt conveyors, which adopt perforated food-grade PP / PU conveyor mesh belts. The core consists of a drive motor, a drive roller, a driven roller, a perforated mesh belt, and a 304 stainless steel frame. The perforations in the mesh belt allow for drainage, air bubble penetration, and spray penetration during the washing process. The structure and working principle of the above conveying components are all common knowledge and mature technologies known in the existing technology of food processing machinery, and will not be described in detail here.

[0063] The recognition camera 903 (Hikvision MV-CA013-20GC 1.3-megapixel industrial camera) acquires real-time images of the dishes on the feeding conveyor assembly 1 to identify the type of dish. The electric telescopic rod 901 (Linac LA25 series food-grade servo electric push rod, rated thrust 500N, telescopic speed 15mm / s, protection level IP66, telescopic tube 304 stainless steel, food-grade lubrication) can drive the camera gimbal 902 (Padway PT-GD201-SS304 stainless steel waterproof two-dimensional electric gimbal) to extend and retract vertically, adjusting the shooting height of the recognition camera 903. The camera gimbal 902 can drive the recognition camera 903 to adjust the shooting angle to adapt to dishes with different stacking heights and sizes, ensuring recognition accuracy. The recognition results are synchronously transmitted to the main controller of the equipment to provide signal basis for subsequent diversion actions.

[0064] The circulating pump 1001 provides power and pumps the wastewater in the corresponding cleaning tank into the filter box 1002 through the water pumping pipe 1004 to complete the purification. The purified water returns to the circulating pump 1001 through the suction pipe 1007 and is finally delivered to the spray end, realizing independent water circulation, filtration and spraying operations for each cleaning tank. The water only circulates within the corresponding tank and the spraying mechanism, and there is no cross-tank flow.

[0065] It is worth noting that, in this embodiment, due to the different water circulation, filtration, and spraying requirements of the leafy vegetable washing tank 3, the melon and fruit washing tank 4, and the root and stem vegetable washing tank 5, the circulating pumps 1001 used are also different:

[0066] Leafy vegetable washing tank 3 is equipped with a circulating pump body 1001: food-grade 304 stainless steel light centrifugal pump, model CHL2-20 from Nanfang Pump Industry, suitable for low-pressure spraying conditions.

[0067] Fruit and vegetable washing tank 4 is equipped with a circulating pump body 1001: food-grade 304 stainless steel light centrifugal pump, model CHL4-30 of Nanfang Pump Industry, suitable for medium-pressure spraying conditions.

[0068] Root and tuber cleaning tank 5 is equipped with a circulating pump body 1001: food-grade 304 stainless steel light centrifugal pump, model CHL8-40 of Nanfang Pump Industry, suitable for high-pressure spraying conditions.

[0069] The selection, installation, and use of the pumps mentioned above are all conventional designs and mature technologies known in the existing technology of fluid transport and cleaning machinery, and will not be described in detail here.

[0070] Leafy vegetables (such as spinach) are cleaned using the first cleaning mechanism 12. The blower 1201 (Full Wind RB-400A, maximum wind pressure 8kPa, air volume 85m³ / h, protection level IP54, oil-free operation, aluminum alloy shell) generates compressed air, which is distributed to each aeration head 1203 (FT-260 food-grade silicone membrane disc microporous aeration head, bubble diameter: 1~3mm (fine and uniform, gently rolling the leafy vegetables without damage), with a built-in check structure to prevent backflow and clogging when the machine stops) in the water. A large number of fine bubbles are generated in the water, and the micro-impact of the rising and breaking of the bubbles achieves non-contact gentle cleaning.

[0071] For fruits and vegetables (such as tomatoes), a second cleaning mechanism 14 is used. A pair of soft nylon brush rollers 1401 rotate at low speed to gently brush the surface of the fruits and vegetables to remove dirt without hard friction damage.

[0072] For root vegetables (such as potatoes), a third cleaning mechanism 16 is used, which uses a hard brush roller with 3 reverse rollers and 2 unidirectional rollers arranged in an alternating pattern to create a continuous scrubbing effect and powerfully remove the clumps of mud and roots from the surface of the root vegetables.

[0073] The identification and classification mechanism 9 also includes a pair of side outlets 904, both of which are carved into the side wall of the feeding and conveying assembly 1. A pair of L-shaped plates 906 are fixedly connected to the top of the feeding and conveying assembly 1. A flexible classification baffle 905 is rotatably connected between the inner top of the L-shaped plate 906 and the inner bottom of the side outlet 904 through a bearing. A first servo motor 907 is fixedly connected to the top of the L-shaped plate 906. The output end of the first servo motor 907 is fixedly connected to the rotating shaft on the top of the flexible classification baffle 905. A first inclined guide plate 908 is provided at the end of the feeding and conveying assembly 1. The first inclined guide plate 908 is fixedly connected to the leafy vegetable washing tank 3. A second inclined guide plate 909 is fixedly connected between the pair of side outlets 904 and the melon and fruit washing tank 4 and the root and stem washing tank 5. The inclined top of the second inclined guide plate 909 is flush with the inner bottom of the side outlet 904.

[0074] Based on the recognition result from the recognition camera 903, the main controller drives the corresponding first servo motor 907 (Huichuan ISMH1-10B30CB-U231Z, rated speed 3000r / min, rated torque 0.32). The rotation of the (IP65 protection rating, 17-bit magnetic encoder) drives the flexible sorting baffle 905 (food-grade silicone wrapped with 304 stainless steel base) to rotate and open, allowing the corresponding vegetables to be discharged from the side outlet 904. They then slide into the corresponding fruit and vegetable washing tank 4 and root vegetable washing tank 5 through the second inclined guide plate 909 (in this embodiment, the first inclined guide plate 908 (inclination angle 15°~25°) and the second inclined guide plate 909 (inclination angle 25°~35°) are both made of 304 food-grade stainless steel with mirror polished surfaces). Leafy vegetables slide straight into the leafy vegetable washing tank 3 through the first inclined guide plate 908 at the end of the feeding conveyor component 1, achieving precise diversion of the three types of vegetables. Specific Implementation Example 2:

[0076] Please see Figure 1 and Figures 4-6 As shown, in a preferred embodiment, each of the three circulating spray mechanisms 10 further includes a removable filter screen 1005 and a removable activated carbon filter layer 1006. Both the removable filter screen 1005 and the removable activated carbon filter layer 1006 are disposed inside the filter box 1002. The drain ends of the three circulating pump bodies 1001 are all fixedly connected to water-guiding sealing pipes 1008, and the other end of the water-guiding sealing pipes 1008 is closed. The three water-guiding sealing pipes 1008 are respectively fixedly connected to the leafy vegetable washing... Multiple water outlet pipes 1009 are fixedly connected to the top of the trough 3, the fruit and vegetable washing trough 4, and the root and stem washing trough 5, and to the outer wall of the water guiding sealing pipe 1008. Multiple first nozzles 11 are fixedly connected to the bottom of the multiple water outlet pipes 1009 on the leafy vegetable washing trough 3. Multiple second nozzles 13 are fixedly connected to the bottom of the multiple water outlet pipes 1009 on the fruit and vegetable washing trough 4. Multiple third nozzles 15 are fixedly connected to the bottom of the multiple water outlet pipes 1009 on the root and stem washing trough 5.

[0077] In the specific implementation process, after the wastewater enters the filter box 1002, it first passes through the detachable filter screen 1005 (304 stainless steel perforated filter screen, 100 mesh) to filter out large particles of impurities such as vegetable leaves and mud. Then, it passes through the detachable activated carbon filter layer 1006 (food-grade coconut shell activated carbon filter media, food-grade PP filter shell) to adsorb pesticide residues, odors, and fine suspended solids, completing the secondary purification. The purified water is pumped into the water guide sealing pipe 1008 through the circulation pump body 1001, and then distributed to the appropriate outlet pipes 1009. The spray nozzles achieve differentiated spraying through the first nozzle 11 (food-grade 304 stainless steel wide-angle atomizing fan-shaped nozzle, orifice diameter φ2.0~2.5mm, spray angle 90°~120°), the second nozzle 13 (food-grade 304 stainless steel standard fan-shaped nozzle, orifice diameter φ1.5~2.0mm, spray angle 60°~90°), and the third nozzle 15 (food-grade 304 stainless steel solid cone-shaped direct spray nozzle, orifice diameter φ1.0~1.5mm, spray angle 30°~60°).

[0078] It is worth noting that in this embodiment, the detachable filter screen 1005 and the detachable activated carbon filter layer 1006 are assembled using a snap-on quick-release structure. The two are stably and detachably joined by elastic snaps, allowing for quick and easy assembly, positioning, and replacement by hand without any auxiliary tools. This facilitates daily cleaning, maintenance, and periodic replacement. The aforementioned detachable connection methods are all conventional quick-release designs and mature technologies known in the prior art, and are common assembly methods familiar to those skilled in the art. Therefore, they will not be described in further detail in this application.

[0079] All three filter boxes 1002 have open tops, and the tops of the filter boxes 1002 are connected to a sealing cover 1003 by screws.

[0080] The sealing cover 1003 enables the filter box 1002 to be sealed and quick-released, facilitating filter element replacement. In this embodiment, a food-grade silicone rubber sealing ring is provided between the mating surfaces of the filter box 1002 and the sealing cover 1003, providing waterproof sealing. This is a conventional design and mature technology in existing sealing technologies, and will not be described in detail or illustrated here.

[0081] The blower 1201 is installed on the side wall of the leafy vegetable washing tank 3, the air guide pipe 1202 is installed on the inner bottom of the leafy vegetable washing tank 3, and multiple aeration heads 1203 are installed on the top of the air guide pipe 1202 and multiple aeration heads 1203 are located at the bottom of the leafy vegetable washing and conveying assembly 6.

[0082] Aeration heads 1203 are located at the bottom of the conveyor assembly. Air bubbles pass through the mesh belt from bottom to top, causing the food to suspend and tumble, achieving thorough cleaning without dead angles. Specific Implementation Example 3:

[0084] Please see Figure 1 and Figures 7-9 As shown, in a preferred embodiment, the second cleaning mechanism 14 further includes a pair of pulleys 1402, a transmission belt 1403 connecting the pair of pulleys 1402, and both pulleys 1402 are fixedly connected to the outer wall of the roller shaft of the soft nylon brush roller 1401. Both soft nylon brush rollers 1401 are located on the inner wall of the fruit and vegetable cleaning tank 4, and the roller shafts of both soft nylon brush rollers 1401 are rotatably connected to the side walls of the fruit and vegetable cleaning tank 4 and the fruit and vegetable cleaning conveying assembly 7 respectively through bearings. A first detachable protective frame 1405 is installed on the side of the fruit and vegetable cleaning tank 4 near the pulleys 1402, and both the pulleys 1402 and the transmission belt 1403 are located inside the first detachable protective frame 1405. A second servo motor 1404 is fixedly connected to the inner wall of the first detachable protective frame 1405, and the output end of the second servo motor 1404 is fixedly connected to the roller shaft of one of the soft nylon brush rollers 1401.

[0085] In the specific implementation process, the soft nylon brush roller 1401 (the brush bristles are food-grade PA610 nylon monofilaments with a diameter of 0.25mm, and the roller body is made of 304 stainless steel) and the second servo motor 1404 (Huichuan ISMH1-20B30CB-U231Z, rated speed 3000r / min, rated torque 0.64) are used. The system (with an IP65 protection rating) drives one of the fine, soft nylon brush rollers 1401 to rotate. This rotation is achieved via a pulley 1402 (in this embodiment, pulley 1402 is made of food-grade reinforced nylon 66 and is a circular-tooth synchronous pulley, possessing waterproof, rust-proof, non-contaminating, lightweight, and wear-resistant properties; the transmission belt 1403 is a food-grade polyurethane synchronous belt with a glass fiber reinforced core, possessing waterproof, oil-resistant, food-grade, washable, and non-stretching deformation characteristics; when used together, the synchronous transmission accuracy coefficient is ≥99.5%). The tensile deformation coefficient is ≤0.1%, the anti-slip coefficient is ≥0.8, the waterproof rating reaches IPX7, and the speed synchronization coefficient is ≤±0.2%, which can ensure that the two soft nylon brush rollers 1401 achieve synchronous and stable transmission in the same direction without slippage or loss of rotation. The synchronous transmission of the transmission belt 1403 drives the other soft nylon brush roller 1401 to rotate synchronously in the same direction, so as to achieve uniform and light brushing of the fruit skin on the conveyor belt. The first detachable protective frame 1405 completely isolates the transmission components from the cleaning area, is waterproof and dustproof, and is easy to disassemble and maintain.

[0086] It is worth noting that in this embodiment, both the first detachable protective frame 1405 and the second detachable protective frame 1605 adopt a detachable connection method using hand-tightened quick-release bolts and positioning clips. This, combined with the pre-set insertion grooves on the side wall of the tank, enables quick assembly and disassembly without the need for special tools. The disassembly and assembly operations are simple, facilitating the inspection, cleaning, and maintenance of the internal transmission mechanism. The aforementioned detachable connection methods are all conventional designs and mature technologies known in the prior art, and will not be described in detail or illustrated here. Specific Implementation Example 4:

[0088] Please see Figure 1 and Figures 10-14 As shown, in a preferred embodiment, the third cleaning mechanism 16 further includes three third servo motors 1604. The output ends of the three third servo motors 1604 are respectively fixedly connected to the roller shafts of three first wear-resistant nylon hard bristle brush rollers 1601. The three first wear-resistant nylon hard bristle brush rollers 1601 and the two second wear-resistant nylon hard bristle brush rollers 1602 are all located inside the root and stem cleaning tank 5, and the three first wear-resistant nylon hard bristle brush rollers 1601 and the two second wear-resistant nylon hard bristle brush rollers 1602 are respectively connected to the root and stem cleaning tank via bearings. The side walls of the trough 5 and the root and tuber cleaning and conveying assembly 8 are rotatably connected. A pair of second detachable protective frames 1605 are installed on both sides of the root and tuber cleaning trough 5, and three third servo motors 1604 are respectively fixedly connected to the inner walls of the pair of second detachable protective frames 1605. A pair of meshing gears 1603 are provided inside the pair of second detachable protective frames 1605, and the pair of meshing gears 1603 are respectively fixedly connected to the outer walls of the adjacent first wear-resistant nylon hard bristle brush roller 1601 and second wear-resistant nylon hard bristle brush roller 1602 roller shafts.

[0089] In the specific implementation process, the third servo motor 1604 (Huichuan ISMH1-40B30CB-U231Z, rated speed 3000r / min, rated torque 1.27) was used. The first wear-resistant nylon bristle brush roller 1601 is driven to rotate by a gear 1603 (304 food-grade stainless steel, module 1.5, number of teeth 20, precision grade 8 (GB / T10095), meshing clearance 0.10~0.20mm, mirror polished surface, Ra≤0.8μm), which in turn drives the adjacent second wear-resistant nylon bristle brush roller 1602 to rotate synchronously in the opposite direction. The first wear-resistant nylon bristle brush roller 1601 (the brush rollers 1601 and 1602...) The first roller (made of food-grade PA66 nylon monofilament with a diameter of 0.4mm and a roller body of 304 stainless steel) rotates in the opposite direction to the conveying direction, creating a rubbing and scrubbing effect and extending the washing time of the food. The second roller (made of wear-resistant nylon hard bristles, 1602) rotates in the same direction as the conveying direction, creating a forward pushing force to prevent food from getting stuck. The three reverse rollers and two co-directional rollers are arranged in an alternating pattern to form a continuous "rubbing-pushing" cycle, achieving 360° powerful cleaning of root vegetables without dead angles. The second detachable protective frame (1605) isolates the third servo motor (1604) and transmission gear (1603) from the cleaning area, making it waterproof, dustproof, and easy to maintain.

[0090] It is worth noting that in this embodiment, all bearings in the rotating parts of this solution are food-grade double-sided sealed deep groove ball bearings, which meet the hygiene and safety requirements of food processing machinery. The specific models are as follows:

[0091] The rotating shaft of the flexible sorting baffle 905 is equipped with a 6203-2RS food-grade deep groove ball bearing.

[0092] The roller shaft bearings for the soft nylon brush roller 1401 and the hard brush roller 1601 / 1602 are: 6205-2RS food-grade deep groove ball bearings.

[0093] Conveyor component roller bearings: 6204-2RS food-grade deep groove ball bearings;

[0094] The bearings mentioned above all use NSF H1 grade food-grade grease. Their selection, installation, and lubrication are all common knowledge and mature technologies known in the existing technology of rotary transmission in food machinery, and will not be described in detail here.

[0095] The first wear-resistant nylon bristle brush roller 1601 rotates in the opposite direction to the conveying direction of the root and tuber cleaning and conveying assembly 8, while the second wear-resistant nylon bristle brush roller 1602 rotates in the same direction as the conveying direction of the root and tuber cleaning and conveying assembly 8.

[0096] The first wear-resistant nylon bristle brush roller (1601) rotates in the opposite direction to the root and stem cleaning conveying assembly (8), which can create a rubbing and scrubbing effect on root and stem vegetables, prolong the brushing contact time, and enhance the removal effect of mud, sand and roots; the second wear-resistant nylon bristle brush roller (1602) rotates in the same direction as the conveying direction, which can create a smooth forward pushing force on the vegetables, avoiding food jamming and spinning in place; the two work together to achieve "powerful scrubbing + smooth pushing" simultaneously, allowing root and stem vegetables to be tumbled and cleaned 360° without dead angles, effectively improving the cleaning cleanliness and the stability of continuous operation of the equipment.

[0097] A method for operating an automated equipment for sorting and cleaning multiple types of vegetables includes the following steps:

[0098] S1: Feeding and Identification: The pre-treated leafy vegetables, melons and fruits, and root vegetables are mixed and placed on the feeding and conveying assembly 1; during the conveying process, the vegetables pass under the identification and classification mechanism 9, where the identification camera 903 performs image acquisition and category identification.

[0102] S3: Differentiated Cleaning

[0103] S3a: Vegetables entering the leafy vegetable washing tank 3 are carried and conveyed by the leafy vegetable washing and conveying assembly 6; the first washing mechanism 12 is started, the fan 1201 supplies air to the air pipe 1202, and the air bubbles generated by the aeration head 1203 gently tumble and wash the vegetables; at the same time, the circulating spraying mechanism 10 of the tank works, and the filtered water is sprayed and rinsed on the vegetables through the first spray head 11.

[0106] S4: Water circulation: Wastewater generated during the cleaning process in each cleaning tank is pumped into the corresponding filter box 1002 through its own pumping pipe 1004. After being filtered and purified by the detachable filter screen 1005 and the detachable activated carbon filter layer 1006, it is pumped back by the circulation pump body 1001 to form an independent internal circulation.

[0107] S5: Discharge: The cleaned vegetables are conveyed out of their respective cleaning tanks by the leafy vegetable cleaning conveyor component 6, the melon and fruit cleaning conveyor component 7, and the root and stem vegetable cleaning conveyor component 8, completing the sorting and cleaning operation.

[0108] The circuits, electronic components, and chip modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve improvements to the software and methods.

The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0110] It is worth noting that in this embodiment, the main controller uses a Siemens S7-1200 PLC, which is a general-purpose main controller for automated food processing equipment. In this solution, all electric devices (electric telescopic pole 901, camera gimbal 902, recognition camera 903, first servo motor 907, circulating pump 1001, fan 1201, second servo motor 1404, third servo motor 1604, and drive motors for each conveying component) are electrically connected to the main controller. The collaborative control logic is as follows: the recognition camera 903 transmits the collected food images to the main controller; the main controller identifies the type of food using its built-in algorithm and then outputs a control signal to the corresponding first servo motor 907. 07.

This algorithm uses a convolutional neural network (CNN) as its core framework and has been optimized for lightweight and real-time performance in industrial assembly line scenarios. Its core working logic is as follows: The recognition camera 903 collects images of vegetables on the conveyor belt in real time. The algorithm first performs preprocessing operations such as denoising and normalization on the images, and then extracts image features of leafy vegetables, root vegetables, and fruits through convolutional layers to complete target detection and category classification. The algorithm simultaneously outputs the location information and classification results of the vegetables, and provides a trigger signal for the main controller to drive the flexible classification baffle 905 to perform diversion actions. The algorithm adapts to the lighting environment and vegetable stacking form in the clean vegetable processing workshop through pre-training and scenario-based transfer learning, and can achieve high accuracy recognition under high-speed conveying conditions. This deep learning-based industrial vision vegetable recognition and classification algorithm is a known conventional design and mature technology in the existing technology of food processing and industrial sorting. Its algorithm principle, model training method, and industrial scenario deployment application have all been commercially deployed on a large scale.

S3: Differentiated Cleaning S3a: Vegetables entering the leafy vegetable washing tank (3) are carried and transported by the leafy vegetable washing and conveying assembly (6); the first washing mechanism (12) is started, the fan (1201) supplies air to the air pipe (1202), and the air bubbles generated by the aeration head (1203) gently tumble and wash the vegetables; at the same time, the circulating spraying mechanism (10) of the tank works, and the filtered water is sprayed and rinsed on the vegetables through the first spray head (11); S3b: The vegetables entering the fruit and vegetable washing tank (4) are carried and conveyed by the fruit and vegetable washing and conveying assembly (7); the second washing mechanism (14) is started, and the second servo motor (1404) drives a pair of soft nylon brush rollers (1401) to rotate and gently brush the surface of the vegetables; at the same time, the circulating spraying mechanism (10) of the tank works, and the filtered water is sprayed and rinsed on the vegetables through the second nozzle (13); S3c: The vegetables entering the root and stem cleaning tank (5) are carried and transported by the root and stem cleaning conveying assembly (8); the third cleaning mechanism (16) is started, the third servo motor (1604) drives the first wear-resistant nylon hard bristle brush roller (1601) to rotate in the opposite direction, and drives the second wear-resistant nylon hard bristle brush roller (1602) to rotate in the forward direction through the gear (1603), so as to perform strong friction and scrubbing on the vegetables; at the same time, the circulating spray mechanism (10) of the tank works, and the filtered water is sprayed and rinsed on the vegetables with high pressure through the third nozzle (15); S4: Water circulation: Wastewater generated during the cleaning process in each cleaning tank is pumped into the corresponding filter box (1002) through its own water pumping pipe (1004). After being filtered and purified by the removable filter screen (1005) and the removable activated carbon filter layer (1006), it is pumped back by the circulation pump body (1001) to form an independent internal circulation. S5: Discharge: The cleaned vegetables are conveyed out of their respective cleaning tanks by the leafy vegetable cleaning conveyor (6), melon and fruit cleaning conveyor (7), and root vegetable cleaning conveyor (8), completing the sorting and cleaning operation.
