Description

Technical Field

[0001] This invention relates to the field of agricultural product processing technology, and in particular to a vegetable processing device and processing method. Background Technology

[0002] In actual fresh food operations and agricultural product distribution scenarios, leafy vegetables, as an indispensable core fresh food category in residents' daily diet and with extremely high consumption frequency, also possess typical characteristics of high perishability, such as high freshness, easy water loss, easy spoilage, and short shelf life. This makes them a key focus and challenge for the operation and management of channels such as supermarkets, farmers' markets, fresh food e-commerce, and central kitchens. Different leafy vegetable varieties exhibit significant differences in morphology, edible parts, preservation requirements, and processing standards, making it difficult to standardize processing procedures and operational norms. Consequently, pre-processing steps such as sorting, trimming, root removal, leaf peeling, and washing after harvesting still largely rely on manual labor.

[0003] This traditional manual operation mode has obvious shortcomings: on the one hand, the overall operation efficiency is low, the manual processing speed is limited and the time consumption is long, and the skill level of personnel varies, making it difficult to form a stable and efficient production output; on the other hand, the standardization level is seriously insufficient, lacking a unified and quantifiable operating standard and quality control system. During peak order periods such as holidays and promotional activities, there is a high risk of a sharp increase in concentrated inventory pressure and a situation where production capacity cannot keep up with demand. At the same time, quality instability problems such as incomplete root removal, incomplete cleaning of old and yellow leaves, mud and sand residue, and substandard cleanliness frequently occur.

[0004] The aforementioned problems not only directly increase the product defect rate and loss rate, and increase operating costs, but also pose potential food safety risks due to hidden dangers such as foreign object residue and incomplete cleaning, affecting consumer experience and brand reputation, and significantly restricting supply chain stability, food safety control, and large-scale and standardized operations.

[0084] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0085] During post-harvest processing of leafy vegetables, their high respiration rate and thin-walled tissue structure make them susceptible to moisture evaporation and mechanical damage during pre-treatment stages such as sorting, trimming, root removal, and washing. Different leafy vegetable varieties exhibit fundamental differences in anatomical structure (e.g., petiole vascular bundle distribution density, leaf epidermal thickness) and physiological requirements (e.g., suitable humidity threshold, critical mechanical strength value), making it difficult to uniformly set processing parameters. Traditional manual processing methods suffer from inconsistent operator skill levels and a lack of quantitative control standards, resulting in significant fluctuations in efficiency and poor quality consistency. Specifically, this manifests as deviations in root removal location, increased leaf damage rates, and unstable washing cleanliness, ultimately leading to higher product defect rates and accumulated food safety risks.

[0086] If the aforementioned problems persist, they will lead to a systemic increase in product loss rates within the supply chain, increasing operational costs. Simultaneously, the continued accumulation of risks from foreign matter residue and microbial contamination could trigger food safety incidents and damage consumer trust. Furthermore, the unpredictability of processing efficiency restricts the system's responsiveness to changes in market demand, hindering the standardization and scaling up of the fresh food distribution industry.

[0087] In response to the above problems, combined with Figures 1 to 33 This embodiment provides a vegetable processing device, including:

[0088] The rack 100 includes a first frame and a second frame; the height of the first frame is greater than the height of the second frame.

[0089] The sorting mechanism 10 is installed on the top of the first frame; the sorting mechanism 10 includes a delivery platform 103, a power module 104 and a push plate 102 that is connected to the power module 104 in a transmission manner; the delivery platform 103 has an input port;

[0090] The conveying mechanism 20 includes a chain 203 fixed to both sides of the first frame according to a first preset path and a basket 30 that moves along the chain 203; the basket 30 is used to load vegetables that are put in from the inlet.

[0091] The root-cutting mechanism includes a guillotine module 41 and a first scissor push module 42 respectively installed on both sides of the first frame; the first scissor push module 42 pushes the vegetables in the basket 30 closer to the guillotine module 41, and the guillotine module 41 cuts off the roots of the vegetables to obtain leaves;

[0092] The primary cleaning mechanism 50 includes a water circulation soil removal module and a drying module 511 located on top of the water circulation soil removal module; the water circulation soil removal module includes a water supply module, a first spray module connected to the water supply module, and a plurality of first brushes 506 moving according to a second preset path; the first spray module and the first brushes 506 perform primary cleaning of the leafy vegetables in the hanging basket 30.

[0093] Separation mechanism 60 is installed on the top of the second frame; separation mechanism 60 includes a primary conveying module 601, a secondary conveying module 602 located below the primary conveying module 601, and a second brush 603 located on the secondary conveying module 602.

[0094] A flipping sorting mechanism 70 is located below the secondary conveying module 602. The flipping sorting mechanism 70 includes a first drive shaft 702 with a drive source, a lifting rod 706 located on the first drive shaft 702, and a bidirectional flipping plate 703. The lifting rod 706 of the first drive shaft 702 rotates in different directions, causing the bidirectional flipping plate 703 to flip in both directions.

[0095] A transfer mechanism 80 is located close to the flipping and sorting mechanism 70; the transfer mechanism 80 includes two conveyor belts 801 assembled in a V-shape; the two conveyor belts 801 are driven by differential gear meshing and are rotated by two universal couplings to transmit torque, so that the blades are changed from horizontal placement to vertical transport.

[0096] A secondary cleaning mechanism 604 is installed above the transfer mechanism 80; the secondary cleaning mechanism 604 is used to perform secondary cleaning of the blades inside the transfer mechanism 80.

[0097] A quantitative packaging mechanism 90 is disposed near the transfer mechanism 80; the quantitative packaging mechanism 90 includes a bag buffer mechanism, a scissor push mechanism, and a weighing platform 923; the bag buffer mechanism is configured to pre-store and transport bags; the scissor push mechanism is configured to grip, open, and move bags; and the weighing platform 923 is configured to measure the weight of the blades inside the bags.

[0098] For ease of understanding, the following explains some key terms in this embodiment:

[0099] Vegetable processing equipment refers to a system of devices used for automated or semi-automated pre-processing of various leafy vegetables, designed to improve processing efficiency, ensure product quality, and reduce labor costs. This equipment typically integrates multiple functional modules to achieve continuous operation from vegetable input to final packaging.

[0100] The frame 100 is the supporting structure of the vegetable processing device, used to support and fix the various functional modules of the device. The frame 100 includes a first frame and a second frame, wherein the height of the first frame is designed to be higher than the height of the second frame to accommodate the space layout requirements of different processing stages.

[0101] The sorting mechanism 10 is a module used to receive vegetables to be processed and to initially sort or guide them to subsequent processing stages. The sorting mechanism 10 typically includes a delivery platform 103 for receiving large quantities of vegetables, a power module 104, and a pusher plate 102. The power module 104 drives the pusher plate 102 to push the vegetables into the delivery platform 103 through an inlet. A platform top plate 101 is provided on top of the delivery platform 103 to protect the power module 104.

[0102] The conveying mechanism 20 is a module responsible for transporting vegetables or leaves within the device. This conveying mechanism 20 typically consists of a chain 203 and a basket 30. The chain 203 moves along a preset path, driving the basket 30 to move between different processing stations. The basket 30 is designed to safely and efficiently load vegetables fed through the inlet.

[0103] The root-cutting mechanism is a module used to remove the roots of vegetables. This mechanism typically includes a guillotine module 41 and a first scissor push module 42. The first scissor push module 42 precisely pushes the vegetables in the basket 30 toward the guillotine module 41, which cuts off the roots of the vegetables through a cutting action, thereby obtaining the edible leaf parts.

[0104] The primary cleaning mechanism 50 is a module used for preliminary cleaning of the leaves to remove dirt and impurities. This mechanism includes a water-circulating soil-removing module and a drying module 511 located on top of the water-circulating soil-removing module. The water-circulating soil-removing module typically includes a water supply module, a first spray module, and multiple first brushes 506, which, through a combination of spraying and brushing, thoroughly clean the leafy vegetables in the hanging basket 30. The drying module 511 is used for preliminary drying of the leaves after cleaning.

[0105] The separation mechanism 60 is a module used to initially disperse and arrange the cleaned blades. This mechanism typically includes a primary conveying module 601, a secondary conveying module 602, and a second brush 603. The blades are initially dispersed by the primary conveying module 601 and then fall to the secondary conveying module 602, where the second brush 603 further assists in the separation and arrangement of the blades.

[0106] The flipping and sorting mechanism 70 is a module used for flipping and sorting blades. This mechanism typically includes a first drive shaft 702 with a drive source, a lifting rod 706 mounted on the first drive shaft 702, and a bidirectional flipping disc 703. The lifting rod 706 rotates in opposite directions, driving the bidirectional flipping disc 703 to flip in both directions, thereby achieving precise flipping and guidance of the blades.

[0107] The transfer mechanism 80 is a module used to change the direction and attitude of the blades being transported. This mechanism typically includes two conveyor belts 801 assembled in a V-shape, driven by differential gears and rotated by two universal couplings, changing the blades from a horizontally placed state to a vertical transport state for subsequent processing.

[0108] The secondary cleaning mechanism 604 is a module used for deeper cleaning of the blades. This mechanism is usually installed above the transfer mechanism 80 to perform a second spray cleaning on the blades transported within the transfer mechanism 80, ensuring that the cleanliness of the blades reaches a higher standard.

[0109] The quantitative packaging mechanism 90 is a module used for weighing and packaging the processed blades. This mechanism typically includes a bag buffer mechanism, a scissor lift mechanism, and a weighing platform 923. The bag buffer mechanism is responsible for pre-storing and conveying the bags, the scissor lift mechanism is responsible for grabbing, opening, and moving the bags, and the weighing platform 923 performs precise weight measurement of the blades inside the bags to achieve standardized packaging.

[0110] The embodiments of this vegetable processing device are designed to provide an efficient and standardized solution for processing leafy vegetables.

[0111] Specifically, the device includes a frame 100, which serves as the skeleton of the entire system and is composed of a first frame and a second frame. The height of the first frame is designed to be higher than that of the second frame. This height difference provides vertical spatial layout flexibility for different processing stages. For example, the higher frame can be used to support modules requiring gravity assistance or higher operating space, while the lower frame can be used to support subsequent processing or collection modules. For instance, the first frame can support modules requiring higher operating heights, such as sorting, conveying, and cutting, while the second frame can support modules such as separation, flipping, sorting, and packaging.

[0112] The sorting mechanism 10 is installed on top of the first frame, and its main function is to receive vegetables to be processed and orderly send them to subsequent stages. Figures 5 to 7The sorting mechanism 10 may include a delivery platform 103 for centrally receiving large quantities of vegetables. A power module 104 drives a pusher plate 102 via a mechanical connection. When vegetables are placed on the delivery platform 103, the power module 104 can drive the pusher plate 102 to reciprocate, pushing the vegetables one by one or in batches towards the inlet on the delivery platform 103. For example, the power module 104 includes a power source such as a servo motor, a synchronous pulley 1041 connected to the output end of the power source, and a first synchronous belt 1042 tensioned to the synchronous pulley 1041. The pusher plate 102 may be a flat plate structure, which pushes the vegetables from the surface of the delivery platform 103 into the inlet through its movement. The side of the pusher plate 102 extends out of the delivery platform 103 and connects to the first synchronous belt 1042. Further, the power module 104 includes a first guide rail 1043 arranged along the length direction of the first synchronous belt 1042 and a first slide table 1044 sliding along the first guide rail 1043. The first slide 1044 is connected to the push plate 102, guiding the forward direction of the push plate 102. Preferably, a first baffle 105 is fixed near the inlet, and the first baffle 105 cooperates with the push plate 102 to feed vegetables into the conveying mechanism 20.

[0113] Combination Figures 8 to 13 The conveying mechanism 20 is responsible for transferring vegetables from the sorting mechanism 10 to the root-cutting mechanism, and further to the subsequent processing station. The conveying mechanism 20 may include chains 203 fixed to both sides of the first frame, which circulate along a preset first path. A basket 30 moving along the chain 203 is used to load vegetables fed from the inlet. For example, the chain 203 is driven by a drive unit to circulate along a guide rail. The basket 30 may be designed with an open top to facilitate loading and unloading of vegetables, and may be hinged or fixed to the chain 203, moving with the chain 203.

[0114] Combination Figure 14 and Figure 15 The root-cutting mechanism is configured to remove the roots of the delivered vegetables. This mechanism includes a guillotine module 41 and a first scissor push module 42, respectively mounted on both sides of the first frame. The first scissor push module 42 is configured to push the vegetables in the basket 30 towards the guillotine module 41. For example, the first scissor push module 42 can be a 28-stepper motor with an encoder, using a scissor structure to push the vegetables forward from the side of the basket 30. The guillotine module 41 is configured to perform a cutting action after the vegetables are pushed into position, removing the roots to obtain the leaves. For example, the guillotine module 41 can consist of a pair of relatively moving blades, driven by a DC geared motor to achieve rapid opening and closing, completing the precise cutting of the vegetable roots.

[0115] Combination Figures 16 to 21The primary cleaning mechanism 50 is used for preliminary cleaning and soil removal of the leaves after root cutting. This mechanism includes a water circulation soil removal module and a drying module 511 located on top of the water circulation soil removal module. The water circulation soil removal module may include a water supply module for providing cleaning water; a first spray module connected to the water supply module for spraying and rinsing the leaves; and multiple first brushes 506 moving along a second preset path for mechanically scrubbing the leaf surface. For example, the water supply module may be a combination of a water pump and a water tank, and the first spray module may consist of multiple nozzles that spray water evenly. The first brushes 506 may be mounted on a rotating shaft and contact the leaves through rotation or reciprocating motion to remove dirt and impurities adhering to the leaves. The drying module 511 may be a hot air drying device for removing most of the moisture from the leaf surface. In this embodiment, the drying module 511 includes a mounting base 5113, a heating fan 5111 fixed to the mounting base 5113, and a heater 5112 fixed to the mounting base 5113 and electrically connected to the heating fan 5111; the air outlet of the heating fan 5111 faces the basket 30.

[0116] Combination Figures 22 to 26 A separation mechanism 60 is mounted on top of the second frame to disperse and initially classify the blades after primary cleaning. The separation mechanism 60 may include a primary conveyor module 601 for receiving blades from the primary cleaning mechanism 50. Below the primary conveyor module 601, a secondary conveyor module 602 is provided. Furthermore, a second brush 603 is provided on the secondary conveyor module 602. For example, the primary conveyor module 601 may be four coaxial differential speed conveyor belts on which the blades are initially spread out. When the blades fall from the primary conveyor module 601 to the secondary conveyor module 602, the second brush 603 may be configured to rotate in the opposite direction to the secondary conveyor module 602, preventing the stacked blades from advancing. The secondary conveyor module 602 then further separates the stacked blades into individual pieces and guides them into subsequent stages.

[0117] Combination Figure 27 and Figure 28 The flipping and sorting mechanism 70 is located below the secondary conveying module 602, and its function is to adjust the attitude and sort the blades. The flipping and sorting mechanism 70 may include a first drive shaft 702 with a drive source, which may be a motor. A lifting rod 706 is provided on the first drive shaft 702, and the mechanism also includes a bidirectional flipping disc 703. For example, the lifting rod 706 can be fixed to the first drive shaft 702. When the first drive shaft 702 rotates in different directions under the drive source, the lifting rod 706 can drive the bidirectional flipping disc 703 to flip bidirectionally. This flipping action allows the blades to be guided to different paths as needed.

[0118] Combination Figure 29 and Figure 30 The transfer mechanism 80 is positioned near the flipping and sorting mechanism 70 to further adjust the conveying posture of the blades. The transfer mechanism 80 may include two conveyor belts 801 assembled in a V-shape. These two conveyor belts 801 are driven by a differential gear. For example, the two conveyor belts 801 may be arranged at a certain angle to each other, forming a V-groove. When the blades enter this V-groove from the flipping and sorting mechanism 70, the differential movement of the two conveyor belts 801 causes the originally horizontally placed blades to gradually rotate and change to a vertical transport state, thus preparing them for subsequent fine processing or packaging.

[0119] A secondary cleaning mechanism 604 is installed above the transfer mechanism 80 to perform a secondary cleaning of the blades after attitude adjustment. The secondary cleaning mechanism 604 can be a spray device, for example, composed of multiple nozzles, to thoroughly rinse the blades transported vertically within the transfer mechanism 80 to remove any remaining fine impurities and further improve the cleanliness of the blades.

[0120] Combination Figures 31 to 33 A quantitative packaging mechanism 90 is positioned near the transfer mechanism 80 for weighing and packaging the final processed blades. The quantitative packaging mechanism 90 may include a bag buffer mechanism for pre-storing and conveying the bags.

[0121] The vegetable processing device in this embodiment achieves automation and continuity of the leafy vegetable processing flow by introducing the coordinated work of multiple functional modules, such as sorting mechanism 10, conveying mechanism 20, root cutting mechanism, primary cleaning mechanism 50, separation mechanism 60, flipping and sorting mechanism 70, transfer mechanism 80, secondary cleaning mechanism 604, and quantitative packaging mechanism 90.

[0122] Specifically, the automated delivery of the sorting mechanism 10 avoids the inefficiency and uncertainty of manual sorting; the basket 30 design of the conveying mechanism 20 ensures stable transmission of vegetables between workstations; the cooperation of the guillotine module 41 and the first scissor push module 42 of the root cutting mechanism achieves precise and efficient root removal, significantly improving the thoroughness and consistency of root removal and reducing leaf damage compared to manual pruning; the dual cleaning mechanism of the primary cleaning mechanism 50 and the secondary cleaning mechanism 604, combined with the physical action of spraying and brushing, ensures high leaf cleanliness, effectively removing dirt and impurities, and solving the problem of insufficient cleanliness in manual cleaning; the combination of the separation mechanism 60, the flipping and sorting mechanism 70, and the transfer mechanism 80 realizes the single-leaf dispersion, posture adjustment, and direction conversion of leaves, providing favorable conditions for subsequent fine processing and packaging, which is an efficiency and precision that is difficult to achieve with traditional manual operation; the automated weighing and packaging of the quantitative packaging mechanism 90 completely solves the problems of low efficiency and inaccurate weight in manual packaging, ensuring product standardization.

[0123] Overall, the device, through the organic integration and automated operation of its various mechanisms, forms a complete and efficient leafy vegetable pretreatment production line. This integrated solution not only significantly improves the efficiency and capacity of leafy vegetable processing and reduces reliance on manual labor, but more importantly, it significantly enhances the standardization and quality stability of product processing, effectively avoiding quality defects and food safety risks associated with traditional manual operations. This provides solid technical support for the large-scale, standardized operation of leafy vegetables.

[0124] This embodiment further proposes that the conveying mechanism 20 also includes a first drive source 201 located on one side of the first frame, a drive sprocket 204 located on the same side of the first drive source 201 and connected to the output end of the first drive source 201, and a plurality of driven sprockets symmetrically located on both sides of the first frame; the drive sprocket 204 and a driven sprocket on the other side are connected by a transmission shaft 202.

[0125] The first drive source 201 is a device that provides power to the conveying mechanism 20. This drive source can take various forms; for example, it can be an electric motor that generates rotational motion through electrical drive. The drive sprocket 204 is a component that directly receives the power output from the first drive source 201 and transmits it to the chain 203. The drive sprocket 204 typically has a tooth profile that matches the pitch of the chain 203, all being 3-point 06B, to ensure smooth and accurate engagement of the chain 203. It is usually fixed to the drive shaft by means of key connection or expansion sleeve connection. The driven sprocket is a component that engages with the chain 203 and is driven to rotate by the chain 203. The main function of the driven sprocket is to support the chain 203, change the direction of movement of the chain 203, and maintain the tension of the chain 203. The driven sprockets can be symmetrically arranged on both sides of the first frame to guide the chain 203 to move along a preset path. The drive shaft 202 is a mechanical component used to transmit torque and rotational motion. The drive shaft 202 can transmit the rotational motion of the drive sprocket 204 to the driven sprocket on the other side, thereby achieving synchronous drive of the chains 203 on both sides. The drive shaft 202 can be in the form of a solid shaft to withstand the transmitted torque.

[0126] In this embodiment, there are seven driven gears on one side of the first frame, namely, a first driven sprocket 205, a second driven sprocket 206, a third driven sprocket 207, a fourth driven sprocket 208, a fifth driven sprocket 209, a sixth driven sprocket 210, and a seventh driven sprocket (not labeled in the figure). Specifically, the first driven sprocket 205 and the sixth driven sprocket 210 are located near the bottom of the frame 100; the second driven sprocket 206 and the fifth driven sprocket 209 are located at the bend of the chain 203 and near the middle of the frame 100; the third driven sprocket 207 and the fourth driven sprocket 208 are located near the top of the frame 100; and the seventh driven sprocket is located near the bottom of the frame 100.

[0127] Specifically, the number of driven gears on each side is determined to be seven, which provides a basis for precise path planning of chain 203 and ensures the structural stability and predictability of the transmission system. These six driven gears are named first driven sprocket 205, second driven sprocket 206, third driven sprocket 207, fourth driven sprocket 208, fifth driven sprocket 209, sixth driven sprocket 210, and seventh driven sprocket, respectively, to facilitate accurate identification and positioning during design, manufacturing, and maintenance. First driven sprocket 205, sixth driven sprocket 210, and seventh driven sprocket are positioned near the bottom of the frame 100. This arrangement is typically used to define the start / end points of the lower return path or load-bearing path of chain 203, providing stable bottom support for the entire transmission cycle. The second driven sprocket 206 and the fifth driven sprocket 209 are located at the bend of the chain 203 and near the center of the frame 100. This is crucial for achieving the inward bend of the chain 203. These driven gears precisely guide the chain 203 to form the required geometry to accommodate the load-bearing requirements of the basket 30 and ensure a smooth transition of fruits and vegetables during transport. The third driven sprocket 207 and the fourth driven sprocket 208 are located near the top of the frame 100. These driven gears typically define the turning points of the upper load-bearing path or return path of the chain 203, ensuring that the chain 203 is effectively guided and supported throughout its entire height range.

[0128] This embodiment further proposes that the central axis of the first driven sprocket 205 and the central axis of the sixth driven sprocket 210 are on the same horizontal line; the central axis of the second driven sprocket 206 and the central axis of the fifth driven sprocket 209 are on the same horizontal line; and the central axis of the third driven sprocket 207 and the central axis of the fourth driven sprocket 208 are on the same horizontal line.

[0129] Specifically, the central axis of the first driven sprocket 205 and the central axis of the sixth driven sprocket 210 are on the same horizontal line. This means that in each set of conveying components 40 of the fruit and vegetable conveying device, the rotation center axes of the first driven sprocket 205 and the sixth driven sprocket 210 located in the bottom area of ​​the frame 100 are precisely arranged on the same horizontal plane. This arrangement ensures that the chain 203 is subjected to uniform force when passing through these two bottom gears, avoiding chain twisting or excessive local tension caused by inconsistent heights.

[0130] Meanwhile, the central axis of the second driven sprocket 206 and the central axis of the fifth driven sprocket 209 are on the same horizontal line. This means that in the conveying mechanism 20, the rotational center axes of the second driven sprocket 206 and the fifth driven sprocket 209, located in the bending section of the chain 203 and near the middle of the frame 100, are precisely arranged on the same horizontal plane. This alignment is crucial for the smooth transition of the chain 203 in the bending area, helping to reduce the impact and friction of the chain at the bend and maintain the smoothness of the transmission.

[0131] Furthermore, the central axis of the third driven sprocket 207 and the central axis of the fourth driven sprocket 208 are on the same horizontal line. This means that in the conveying assembly 40, the rotation center axes of the third driven sprocket 207 and the fourth driven sprocket 208, located in the top region of the frame 100, are precisely arranged on the same horizontal plane. This arrangement ensures the smooth operation of the chain 203 in the top region, especially when the suspended basket 30 rises or falls to its highest point, effectively distributing the load and avoiding localized stress concentration.

[0132] The frame 100 has six mounting plates on one side: a first mounting plate 1001, a second mounting plate 1002, a third mounting plate 1003, a fourth mounting plate 1004, a fifth mounting plate 1005, and a sixth mounting plate 1006. The first mounting plate 1001 is used to mount the first driven sprocket 205, the second mounting plate 1002 is used to mount the second driven sprocket 206, the third mounting plate 1003 is used to mount the third driven sprocket 207, the fourth mounting plate 1004 is used to mount the fourth driven sprocket 208, the fifth mounting plate 1005 is used to mount the fifth driven sprocket 209, and the sixth mounting plate 1006 is used to mount the sixth driven sprocket 210.

[0133] It should be noted that the seventh driven sprocket and the driving sprocket 204 are connected by the drive shaft 202, and no mounting plate is required.

[0134] This embodiment further proposes that the hanging basket 30 includes a boom assembly and a base plate assembly; the conveying mechanism 20 also includes a limiting rod fixed to the first frame, which is located above the separation mechanism 60; after the hanging basket 30 touches the limiting rod, the chain 203 continues to move, and the hanging basket 30 flips around the contact point between the boom of the boom assembly and the limiting rod as the axis, pouring the leafy vegetables in the hanging basket 30 into the separation mechanism 60.

[0135] The boom assembly of the suspended basket 30 is the part that is connected to and suspended by the chain 203 of the conveying mechanism 20, and also serves as a fulcrum for flipping during unloading.

[0136] The boom assembly includes a first boom 301 and a second boom 302 symmetrically arranged along the width direction of the suspended basket 30; both the first boom 301 and the second boom 302 are constructed by sequentially hinged or integrally formed an upper inclined arm, a middle vertical arm and a lower connecting arm; the upper inclined arm ends of the first boom 301 and the second boom 302 are hinged together; the lower connecting arm of the first boom 301 and the lower connecting arm of the second boom 302 are respectively connected to the base plate assembly.

[0137] A connecting shaft 303 is provided at the hinge joint of the first boom 301 and the second boom 302; the connecting shaft 303 is rotatably connected to the first boom 301 and the second boom 302; one end of the connecting shaft 303 is provided with a fixing member 304 that is fixedly connected to the chain 203.

[0138] Specifically, the connecting shaft 303 is located at the hinge of the first boom 301 and the second boom 302. Its main function is to serve as the pivot center of the boom assembly and as the interface for the transmission connection between the basket 30 and the chain 203 of the conveying assembly 40. The connecting shaft 303 is typically a cylindrical rod to bear the weight of the basket 30 and its load, and to ensure structural stability during transmission. The connecting shaft 303 is rotatably connected to both the first boom 301 and the second boom 302, meaning that the first boom 301 and the second boom 302 can rotate freely around the connecting shaft 303, thereby allowing the basket 30 to adjust its posture or angle as needed during transport.

[0139] The fixing element 304 is located at one end of the connecting shaft 303. Its function is to fix the connecting shaft 303 to the chain 203, thereby enabling the chain 203 to directly drive the suspended platform 30. The fixing element 304 can take various forms, such as a connecting block that matches a specific link of the chain 203. This fixed connection ensures that the movement of the chain 203 can be transmitted to the connecting shaft 303 precisely and without gaps, thereby driving the entire suspended platform 30 to move along a preset path.

[0140] The base plate assembly includes a first base plate 305 and a second base plate 306 symmetrically arranged along the length of the suspended platform 30; the first base plate 305 and the second base plate 306 are arranged at a V-shaped angle to each other, together forming the load-bearing bottom surface of the suspended platform 30. In this embodiment, the angle formed between the first base plate 305 and the second base plate 306 is 120°.

[0141] The first base plate 305 and the second base plate 306 together form the load-bearing bottom surface of the hanging basket 30, indicating that these two V-shaped angled base plates are all or the main support structure for the hanging basket 30 to support fruits and vegetables. They work together to form a complete load-bearing area, ensuring that the fruits and vegetables are adequately supported and protected during transportation.

[0142] Furthermore, the adjacent edges of the first base plate 305 and the second base plate 306 are connected by a first connector 308. The first connector 308 is a structural component used to securely connect two or more components together. Its function is to ensure that the first base plate 305 and the second base plate 306 can stably maintain a preset V-shaped angle, forming a complete and reliable load-bearing bottom surface.

[0143] This embodiment further proposes that the hanging basket 30 also includes a set of side plates 307 symmetrically arranged along the length of the hanging basket 30; the set of side plates 307 are respectively connected to the first base plate 305 and the second base plate 306 through the second connector 309. Specifically, the side plates 307 are structural components used to form the side walls of the hanging basket 30, and their main function is to work with the base plate assembly to enclose a more complete load-bearing space to prevent fruits and vegetables from slipping or overflowing from the sides during transportation. The side plates 307 are symmetrically arranged along the length of the hanging basket 30 to ensure that the hanging basket 30 is subjected to uniform force when carrying fruits and vegetables, maintaining structural stability and balance. This symmetrical arrangement helps to maintain the stability of the hanging basket 30 during transportation, reducing swaying and thus reducing the risk of fruits and vegetables being damaged by impact. At the same time, the symmetrical arrangement also makes the load-bearing space of the hanging basket 30 reasonably distributed, facilitating the loading and unloading of fruits and vegetables. The second connector 309 is a component used to mechanically connect the side plates 307 to the first base plate 305 and the second base plate 306.

[0144] Among them, the first base plate 305, the second base plate 306 and the side plate 307 are all hollowed out.

[0145] The limiting rod is a structural component fixed to the first frame. Its function is to provide a fixed contact point when the basket 30 moves to a specific position, allowing the basket 30 to rotate around that point. The limiting rod can be a cylindrical or square metal rod, or a guide rail with a specific cross-sectional shape. Its installation position is crucial; it is precisely positioned directly above the separating mechanism 60 to ensure that the leafy vegetables being unloaded from the rotating mechanism fall accurately into the separating mechanism 60.

[0146] This embodiment achieves automatic unloading of leafy vegetables through ingenious mechanical linkage. When the chain 203 of the conveying mechanism 20 drives the basket 30 along a preset path to above the separation mechanism 60, the boom assembly of the basket 30 contacts the limiting rod fixed on the first frame. At this time, the chain 203 of the conveying mechanism 20 does not stop moving, but continues to drive the basket 30 forward. Because the boom assembly of the basket 30 is blocked by the limiting rod, it cannot continue to move in a straight line with the chain 203, but the continuous tension of the chain 203 will cause the basket 30 to generate a turning torque around the contact point between the boom assembly and the limiting rod. Under the action of this torque, the basket 30 will undergo controlled turning, and its bottom plate assembly will tilt accordingly, smoothly dumping the leafy vegetables it carries into the separation mechanism 60 below. This design utilizes the continuous movement of the conveying chain 203 as the power source for turning, eliminating the need for an additional drive device, achieving passive automatic unloading, thereby simplifying the mechanism design and improving the reliability of the system.

[0147] This embodiment further proposes that the gate module 41 includes a gate fixing seat 414, a second drive source 411 installed on the gate fixing seat 414, a drive wheel 412 connected to the output end of the second drive source 411 and provided with an eccentric shaft, a connecting rod 413 connected to the eccentric shaft, and a blade assembly connected to the connecting rod 413; the rotational motion of the drive wheel 412 is converted into the opening and closing motion of the blade assembly.

[0148] The gate holder 414 serves as the structural foundation for supporting and securing the internal components of the gate module 41. The second drive source 411 provides power to the gate module 41, enabling its blade assembly to open and close. It can be an AC or DC motor, such as a stepper motor or servo motor, driven by electricity. The drive wheel 412 receives power from the second drive source 411 and transmits the rotational motion to the connecting rod 413 via its eccentric shaft. The drive wheel 412 can be a disc with an eccentric hole, fixed to the output shaft of the second drive source 411 via a key or interference fit. The eccentric shaft, located off-center from the rotation axis of the drive wheel 412, connects to the connecting rod 413, converting the rotational motion into the reciprocating motion of the connecting rod 413. The connecting rod 413 connects the eccentric shaft and the blade assembly, responsible for converting the rotational motion of the drive wheel 412 into the opening and closing motion of the blade assembly. It can be a rigid rod, with both ends connected to the eccentric shaft and the blade assembly via pins or spherical bearings. The blade assembly is the component that directly cuts the roots of vegetables. It can be a pair of scissor-shaped blades, driven by the connecting rod 413 to perform the cutting action. The rotational motion of the drive wheel 412 is converted into the opening and closing motion of the blade assembly, which describes the core working principle of the gate module 41. That is, the rotational power of the drive source is converted into the cutting action of the blade assembly through a mechanical transmission mechanism. Through the crank-connecting rod mechanism composed of the eccentric shaft and the connecting rod 413, when the drive wheel 412 rotates, the eccentric shaft drives the connecting rod 413 to reciprocate or move linearly, thereby driving the blade assembly to achieve the opening and closing cutting action.

[0149] The blade assembly described above includes a set of blade holders 415 connected to the connecting rod 413, a blade clamp 416 mounted on the blade holders 415, and a blade 417 mounted on the blade clamp 416.

[0150] This embodiment further proposes that the first scissor lift module 42 includes a third drive source 421, a lead screw slide 422 connected to the output end of the third drive source 421, a first scissor lift unit 423 connected to the movable part of the lead screw slide 422, and a push plate 424 connected to the side of the first scissor lift unit 423 away from the lead screw slide 422.

[0151] The third drive source 421 is a device that provides power to the first scissor lift module 42. It can be various types of motors, such as stepper motors or servo motors, which precisely control the rotation to achieve fine displacement control of the mechanical components. The lead screw slide 422 is a mechanical component that converts rotary motion into high-precision linear motion, typically consisting of a lead screw, a nut, and a guide rail. Under the action of the drive source, the lead screw rotates, and the nut moves along the lead screw axis, thereby driving the components connected to it to perform smooth and precise linear reciprocating motion. The first scissor lift unit 423 is a mechanical structure that uses a linkage mechanism to achieve a telescopic function, characterized by its ability to achieve a large telescopic stroke within a relatively compact space. It typically consists of multiple cross-connected rods, and the movement of a drive point (such as the moving part of the lead screw slide 422) causes the entire unit to extend or shorten in one direction, thus providing stable thrust and maintaining good parallelism. Besides the scissor lift unit, a multi-stage telescopic rod or a parallelogram linkage mechanism can also be used to achieve a similar telescopic function. The push plate 424 is the component that directly contacts the vegetables and applies a pushing force to them. It is typically designed as a flat surface with a certain area to ensure even force distribution when pushing vegetables and avoid damage to them. The shape and size of the push plate 424 can be optimized according to the cross-sectional shape and size of the basket 30 to achieve the best pushing effect.

[0152] This embodiment further proposes a water supply module including a water tank 510, a liquid pump 512 connected to the water tank 510, and a three-way valve 517 connected to the liquid pump 512; the three-way valve 517 is connected to the first spray module; a filter 515 is provided between the liquid pump 512 and the three-way valve 517.

[0153] The water tank 510 is a container for storing cleaning water; it can be an open-type water storage container. Its capacity can be designed according to the cleaning volume and circulation requirements. The liquid pump 512 is a power unit used to extract cleaning water from the water tank 510 and deliver it to downstream components. It can be a centrifugal pump, diaphragm pump, or plunger pump, etc., with the appropriate model selected based on the required flow rate and head to ensure a stable water supply. The three-way valve 517 is a valve with three ports used to control the distribution or switching of fluid between different paths, directing the water delivered by the liquid pump 512 to the first spray module, or performing bypass or backflow operations when needed. The filter 515 is a device for removing impurities from the liquid. It can be a mesh filter, disc filter, sand filter, or activated carbon filter, etc., selected according to the type of impurities to be filtered and the required precision. The filter 515 is typically installed between the outlet of the liquid pump 512 and the inlet of the three-way valve 517 to protect downstream components from particulate clogging. The first spray module is a device used to evenly spray cleaning water onto the leafy vegetables to be cleaned in the form of a spray or a stream. It usually consists of a spray pipe and multiple nozzles. The type and arrangement of the nozzles can be optimized according to the cleaning needs to ensure cleaning coverage and impact.

[0154] This embodiment integrates a water tank 510, a liquid pump 512, a three-way valve 517, and a filter 515 into a water supply module, constructing a highly efficient and controllable water circulation system. Specifically, the water tank 510 serves as a storage unit for cleaning water, ensuring a continuous water supply during the cleaning process. The liquid pump 512 is responsible for drawing and pressurizing the water in the water tank 510, providing the necessary flow and pressure to the first spray module. Before the water flows into the first spray module, the filter 515 effectively intercepts impurities such as mud and debris that may be present in the cleaning water, thereby significantly improving the quality of the cleaning water, preventing nozzle clogging, and extending the service life of the first spray module. The three-way valve 517 provides flexibility in the water flow path; for example, it can control the water flow to be directly delivered to the first spray module for cleaning, or, under certain circumstances, bypass or recirculate part of the water flow to achieve more precise water quantity and quality management. This structural combination ensures the cleanliness and continuity of the cleaning water, thereby guaranteeing the cleaning effect of the primary cleaning mechanism 50 on leafy vegetables and reducing the maintenance requirements of the equipment.

[0155] Furthermore, the inlet of the liquid pump 512 and the water tank 510 are connected through the first connecting pipe 514, and the outlet of the liquid pump 512 and the three-way valve 517 are connected through the second connecting pipe 516, and a filter 515 is provided on the second connecting pipe 516.

[0156] This embodiment further proposes that the first spray module includes a first spray main pipe 507 arranged parallel to the length direction of the first brush 506 and a plurality of first nozzles 508 disposed on the first spray main pipe 507; the outlet of the first nozzle 508 faces the water tank 510. The end of the first spray main pipe 507 is fixed to the spray fixing frame 509.

[0157] The first main spray pipe 507 is the core pipeline for carrying and distributing the cleaning solution. It receives the cleaning solution from the water supply module and delivers it to the various nozzles. Multiple first nozzles 508 are installed on the first main spray pipe 507; these are the components that spray the cleaning solution directly onto the leafy vegetables from the main pipe. These nozzles can be fan-shaped nozzles, cone-shaped nozzles, or atomizing nozzles.

[0158] This embodiment ensures a high degree of matching between the spray area and the cleaning area of ​​the first brush 506 by arranging the first spray main pipe 507 and the first brush 506 parallel in their length directions. This allows the cleaning liquid to directly act on the surface of the leafy vegetables being cleaned by the brush, thereby enhancing the cleaning effect. This parallel arrangement can be achieved by adjusting the axis of the first spray main pipe 507 to keep it parallel to the axis of the first brush 506 during installation, or by designing an adjustable installation structure, such as a slide rail or a rotatable bracket, for fine-tuning to accommodate first brushes 506 of different sizes or arrangements.

[0159] Furthermore, the outlet of the first nozzle 508 faces the water tank 510. This orientation design allows the sprayed cleaning solution to naturally and efficiently flow back into the water tank 510 after cleaning the leafy vegetables. This facilitates the collection and recycling of the cleaning solution, reducing splashing and loss. This design can be achieved by adjusting the installation angle of the first nozzle 508 or by selecting a nozzle with a specific spray direction.

[0160] This embodiment further proposes that the above-mentioned primary cleaning mechanism 50 also includes a fourth drive source 501 and two sets of parallel eccentric couplings; multiple first brushes 506 are connected to the parallel eccentric couplings; one set of parallel eccentric couplings is connected to the output end of the fourth drive source 501, and the two sets of parallel eccentric couplings are symmetrically arranged on both sides of the first brushes 506.

[0161] The fourth drive source 501 is a device that provides mechanical power, serving to provide continuous power input to the brushing components in the primary cleaning mechanism 50. This drive source can take various forms, such as an electric motor, like an AC or DC motor, converting electrical energy into mechanical energy. The parallel eccentric coupling is a mechanical transmission device characterized by its two connected axes being parallel but not overlapping. Through its internal eccentric structure, it can convert input rotational motion into a composite motion with a specific trajectory, such as reciprocating motion. Multiple first brushes 506 are connected to the parallel eccentric coupling, meaning that the movement of the first brushes 506 is directly driven and controlled by the parallel eccentric coupling. This connection can be achieved by fixing the first brushes 506 to the output end of the coupling or by using a bracket, allowing the first brushes 506 to follow the complex motion trajectory generated by the parallel eccentric coupling for brushing. One set of parallel eccentric couplings is connected to the output end of the fourth drive source 501, indicating that the power of the fourth drive source 501 is transmitted to at least one set of parallel eccentric couplings through a mechanical connection. Two sets of parallel eccentric couplings are symmetrically arranged on both sides of the first brush 506. This means that a set of parallel eccentric couplings is configured at each end or on both sides of the first brush 506, and the arrangement of these two sets of couplings is symmetrical. This symmetrical layout aims to ensure that the first brush 506 is subjected to uniform force during movement, avoiding tilting, shaking, or wear caused by uneven force, thereby ensuring the stability and effectiveness of the brushing motion.

[0162] The aforementioned parallel eccentric coupling includes an input disc 502, a parallel connecting rod assembly 503, a floating disc 504, and an output disc 505. The input disc 502 has three evenly distributed hinge points for connecting the input connecting rods; the output disc 505 has three evenly distributed hinge points for connecting the output connecting rods; the floating disc 504 is located between the input disc 502 and the output disc 505, and has two sets of hinge points, which are respectively hinged to the input connecting rods and the output connecting rods; the parallel connecting rod assembly 503 includes multiple input connecting rods for connecting the input disc 502 and the floating disc 504, and multiple output connecting rods for connecting the floating disc 504 and the output disc 505; the input connecting rods and the output connecting rods maintain a parallelogram motion relationship; the input disc 502 of one set of parallel eccentric couplings is connected to the output end of the fourth drive source 501.

[0163] Specifically, the parallel eccentric coupling aims to convert the rotational motion of the drive source into motion with a specific eccentric trajectory while maintaining the parallelism between the output and input ends. Its core lies in ensuring, through a precise mechanical structure, that the output component does not generate additional rotation or oscillation during the eccentric motion, thus providing a stable and controllable cleaning action for the brush 106 connected to it. The input disc 502, as the power input end of the parallel eccentric coupling, is typically fixed to the output shaft of the fourth drive source 501 via keys, pins, or bolts. Three evenly distributed hinge points on the input disc 502, such as pin holes spaced at 120° intervals, are used for hinged connections with the input links. This evenly distributed design helps balance forces, reduce vibration and impact during transmission, and ensure smooth power transmission. The parallel link assembly 503 is a key component for realizing the parallel eccentric motion, consisting of multiple input links and multiple output links. The input links connect the input disc 502 and the floating disc 504, and the output links connect the floating disc 504 and the output disc 505. These connecting rods are hinged together to form a specific linkage mechanism for motion conversion. A floating disk 504 is located between the input disk 502 and the output disk 505, serving as an intermediate transmission component. It has two sets of hinge points: one for hinged to the input connecting rod and the other for hinged to the output connecting rod. During movement, the floating disk 504 undergoes translation and limited rotation, its function being to smoothly transmit the eccentric motion of the input disk 502 to the output disk 505. The output disk 505 serves as the power output end of the parallel eccentric coupling, with three evenly distributed hinge points for hinged to the output connecting rod. The motion trajectory of the output disk 505 is an eccentric circle concentric with the input disk 502, but it does not rotate itself, always maintaining a parallel posture to the input disk 502. The brush 106 is typically fixed to the output disk 505 to achieve stable eccentric cleaning motion. The input and output connecting rods maintain a parallelogram motion relationship, which is the core of the parallel eccentric coupling's function. This means that the input and output links, through a specific geometric configuration during movement, ensure that the output disk 505 does not deflect at an angle during eccentric motion, thus maintaining a parallel posture with the input disk 502. This is crucial for actuators requiring stable direction (such as the first brush 506), ensuring that the brush 106 cleans with a preset posture and trajectory, avoiding uneven cleaning or reduced efficiency due to posture changes. One set of parallel eccentric couplings connects the input disk 502 to the output end of the fourth drive source 501, clearly defining the power transmission path. The rotational motion of the fourth drive source 501 (e.g., a motor) is first transmitted to the input disk 502 of the parallel eccentric coupling, and then converted into the stable eccentric motion required by the first brush 506 through the internal structure of the coupling.

[0164] This embodiment proposes a vegetable processing device, wherein the primary conveying module 601 includes four differential speed vibrating conveyor belts; the secondary cleaning mechanism 604 includes a second spray main pipe 6041 arranged parallel to the width direction of the secondary conveying module 602 and a plurality of second nozzles 6042 disposed on the second spray main pipe 6041; the second nozzles 6042 face the transfer mechanism 80.

[0165] The four-segment differential speed vibrating conveyor belt refers to a system composed of four independent conveyor belt segments, each capable of independent speed adjustment and / or vibration control. Its main function is to receive blades tilted from the basket 30 and, through speed differences and vibration between segments, effectively disperse stacked or adhered blades, allowing them to enter subsequent processing stages as individual pieces. This is achieved by using sleeves of different radii on the same drive shaft to achieve differential speed across the segments. The second spray main pipe 6041 is the core component of the secondary cleaning mechanism 604 for conveying the cleaning fluid. Its function is to provide a stable and sufficient flow of cleaning fluid to multiple second nozzles 6042. Parallel to the width direction of the secondary conveying module 602, this feature describes the installation position of the second spray main pipe 6041. This parallel arrangement ensures that the cleaning fluid can evenly cover the blades conveyed on the transfer mechanism 80, thereby achieving a comprehensive secondary cleaning effect. Multiple second nozzles 6042 are located on the second main spray pipe 6041. These second nozzles 6042 are the actuating components in the secondary cleaning mechanism 604 that directly spray the blades. By setting multiple second nozzles 6042 on the second main spray pipe 6041, a wide spray area can be formed, ensuring that the cleaning fluid can be sprayed onto the blade surface at appropriate pressure and angle to effectively remove residual dirt and impurities. The type of nozzle can be selected according to cleaning requirements, such as fan-shaped nozzles, conical nozzles, or atomizing nozzles. The second nozzles 6042 face the transfer mechanism 80, which defines the spray direction of the second nozzles 6042. Setting the nozzles facing the transfer mechanism 80 means that secondary cleaning is performed during the transfer of the blades from the secondary transfer module 602 to the transfer mechanism 80. This design utilizes the dynamic process during blade transfer, allowing the cleaning fluid to act more effectively on the blades, while ensuring that secondary cleaning is completed before the blades enter the transfer mechanism 80, preparing them for subsequent drying and packaging.

[0166] It should be noted that the liquid pump 512 of the water supply module directs the water flow to the first spray module and the secondary cleaning mechanism 604 respectively through the three-way valve 517.

[0167] This embodiment proposes that the flipping sorting mechanism 70 also includes a fifth drive source 701 connected to the first drive shaft 702, and a first flipping limit seat 704 and a second flipping limit seat 705 respectively disposed on both sides of the bidirectional flipping plate 703.

[0168] In this embodiment, the power source for the transmission belt 801 of the transfer mechanism 80 is a DC geared motor. Torque is transmitted to the transmission belt 801 at a 120° angle via a universal coupling. Two universal couplings are also used between the transmission belts 801 to change the direction of rotation. These universal couplings not only complete three transmission direction changes and two-stage differential belt drive, but their 120° angle design also ensures smooth movement of the mechanism. The transfer mechanism 80 uses two differential gears 802, one with 19 teeth and the other with 15 teeth. The gears 802 are fixed below the transmission belt 801 via universal couplings. This design allows the bottom ends of the V-belts to be fully engaged without hindering the differential transmission of the transmission belt 801 by the gears 802.

[0169] Specifically, the transfer mechanism 80 includes a bearing platform 806, bearing support seats 803 located on both sides of the bearing platform 806, and a second drive shaft 804 and a passive shaft 805 located on both sides of the bearing support seats 803.

[0170] It should be noted that, in combination Figure 24 and Figure 29 The secondary transmission module 603 and the transfer mechanism 80 can share a power source.

[0171] This embodiment proposes a packaging bag buffer mechanism comprising a sixth drive source 901, a first synchronous pulley group, a synchronous belt, and a second synchronous pulley group. The output end of the sixth drive source 901 is connected to the first synchronous pulley group, providing power for the movement of the synchronous belt. The first and second synchronous pulley groups are arranged along a first horizontal direction, forming a closed transmission path. The synchronous belt is tensioned between the first and second synchronous pulley groups to ensure its stability during movement. The loops of the packaging bags are placed on adjacent unit sections of the synchronous belt, and the packaging bags are conveyed one by one to a designated position by the movement of the synchronous belt. The first synchronous pulley group is designed to include a first synchronous pulley 902 and a second synchronous pulley 904 connected to the first synchronous pulley 902 via a first connecting shaft 905. Simultaneously, the output end of the sixth drive source 901 is connected to the first connecting shaft 905. The second synchronous pulley set includes a third synchronous pulley 907 and a fourth synchronous pulley 908 connected to the third synchronous pulley 907 via a second connecting shaft 909. The line connecting the center of the third synchronous pulley 907 and the center of the first synchronous pulley 902 is parallel to the line connecting the center of the fourth synchronous pulley 908 and the center of the second synchronous pulley 904. There are two synchronous belts: a second synchronous belt 903 and a third synchronous belt 906. The second synchronous belt 903 is tensioned between the first synchronous pulley 902 and the third synchronous pulley 907; the third synchronous belt 906 is tensioned between the second synchronous pulley 904 and the fourth synchronous pulley 908. Specifically, the use of two independent synchronous belts for transmission allows for better independence and stability of the transmission system in the lateral direction. Each of the two synchronous belts can bear a portion of the transmission load, thereby reducing the stress on a single synchronous belt and improving the overall reliability of the transmission. The second synchronous belt 903 connects the first synchronous pulley 902 and the third synchronous pulley 907. This means that the second synchronous belt 903 forms an independent transmission loop, driving one side of the packaging bag buffer mechanism 10. This configuration ensures synchronized movement on this side, providing a foundation for stable transport of the packaging bags. The third synchronous belt 906 connects the second synchronous pulley 904 and the fourth synchronous pulley 908. Similar to the second synchronous belt 903, the third synchronous belt 906 also forms an independent transmission loop, driving the other side of the packaging bag buffer mechanism 10. By driving with two synchronous belts separately, it is possible to effectively avoid packaging bag skewing or jamming caused by uneven force on one side.

[0172] The scissor lift mechanism is configured to grab a bag from the bag buffer mechanism, open it, and move it above the weighing platform 923. The mechanism includes a first fixed plate 912 and a second fixed plate 917 arranged vertically and parallel to each other. The first fixed plate 912 and the second fixed plate 917 provide a stable support structure for the scissor lift mechanism.

[0173] The scissor lift mechanism also includes a linear module mounted on the first fixed plate 912. This linear module can be composed of a motor-driven lead screw mechanism, with its movable part configured to move in a linear direction. The linear module includes a seventh drive source 910, a ball screw connected to the output end of the seventh drive source 910, and a set of bearing seats 911 fixed to the first fixed plate 912; the ball screw and the bearing seats 911 form a mating connection.

[0174] The second scissor lift module 916 is located between the first fixed plate 912 and the second fixed plate 917. The second scissor lift module 916 expands the packaging bag through its telescopic movement. One side of the second scissor lift module 916 has a first movable block 913 and a first fixed block 914, and the other side has a second movable block 918 and a second fixed block 919. The first movable block 913 is connected to the movable part of the linear module, and the movement of the linear module drives the extension and retraction of the second scissor lift module 916. The first fixed block 914 is fixed to the first fixed plate 912, providing a fixed fulcrum for the second scissor lift module 916. The second movable block 918 is movably connected to the second fixed plate 917, allowing it to move relative to the second fixed plate 917. The second fixed block 919 is fixedly connected to the second fixed plate 917, serving as another fixed fulcrum for the second scissor lift module 916 on the second fixed plate 917.

[0175] The second scissor lift module 916 includes multiple sets of scissor arms; the end hinge points of the scissor arms near the first fixed plate 912 are respectively connected to the first movable block 913 and the first fixed block 914; the end hinge points of the scissor arms near the second fixed plate 917 are respectively connected to the second movable block 918 and the second fixed block 919; the end hinge points of adjacent scissor arms are connected; wherein the scissor arms include cross-connected rods, and the rods can rotate relative to each other. Specifically, the scissor arms are the basic units constituting the second scissor lift module 916, and are usually formed by two rods cross-connected through a central hinge point. The arrangement of multiple sets of scissor arms means that the second scissor lift module 916 is not composed of a single scissor unit, but is composed of multiple such units combined. This multi-set design can effectively increase the overall length, load-bearing capacity and telescopic stroke of the second scissor lift module 916, and at the same time, through reasonable layout, it can improve its structural stability during telescopic process and reduce swaying and deformation. For example, multiple sets of scissor arms can be connected in series along the telescopic direction to achieve a larger telescopic distance. The end hinge points of the scissor arms near the first fixed plate 912 are respectively connected to the first movable block 913 and the first fixed block 914, which describes the connection method between the second scissor propulsion module 916 and one side of the first fixed plate 912. The end hinge points of the scissor arms are key parts for their connection with external structures, allowing the scissor arms to rotate around these points. The first movable block 913 is generally movable, while the first fixed block 914 is stationary. By connecting the end hinge points of the scissor arms to the movable block and the fixed block respectively, it can be ensured that one side of the second scissor propulsion module 916 can be effectively driven and maintain its relative positional relationship with the first fixed plate 912 during extension and retraction, thereby realizing the deployment or retraction of the scissor mechanism. Similarly, the end hinge points of the scissor arms near the second fixed plate 917 are respectively connected to the second movable block 918 and the second fixed block 919. This connection method ensures that the other side of the second scissor propulsion module 916 can also maintain a stable connection with the second fixed plate 917 during the extension and retraction process, and allows the necessary relative movement to complete the overall extension and retraction of the scissor mechanism. The connection of the end hinge points of adjacent scissor arms refers to the connection method between the various scissor arm units constituting the second scissor propulsion module 916. Typically, the end of one scissor arm unit is connected to the starting end of the next scissor arm unit through a hinge point. This connection method allows multiple scissor arm units to be connected in series to form a continuously extendable integral structure. Through this connection, when one scissor arm unit is driven to extend or retract, its movement can be transmitted to the adjacent scissor arm units, thereby achieving synchronous extension and retraction of the entire module. The scissor arms include cross-connected rods, which can rotate relative to each other; this is the core principle of the scissor mechanism. Each scissor arm unit consists of two links that cross and hinge at their midpoint, allowing them to rotate relative to each other about that hinge point. Additionally, the ends of the links typically also have hinge points for connecting to other links or external structures.When an external driving force is applied to the scissor mechanism, the scissor mechanism can extend or shorten in the length direction through the relative rotation of these links, thereby completing the telescopic function of the second scissor propulsion module 916.

[0176] Furthermore, the scissor lift mechanism also includes a second guide rail 915 fixed to the first fixed plate 912 along the length of the first fixed plate 912; the first movable block 913 slides along the second guide rail 915.

[0177] The scissor lift mechanism also includes a third guide rail 922 fixed to the second fixed plate 917 along the length of the second fixed plate 917; the second movable block 918 slides along the third guide rail 922.

[0178] The scissor pusher mechanism also includes at least one suction cup 921, which is mounted on the second fixed plate 917 and located near the bottom of the second fixed plate 917, and its function is to adsorb the bottom of the packaging bag.

[0179] A hook 920, which is mounted toward the bag buffer mechanism, is installed on the second fixed plate 917. The hook 920 is configured to engage with the bag's lugs when the second scissor push module 916 extends or retracts, thereby gripping and opening the bag.

[0180] A weighing platform 923 is disposed between the packaging bag buffer mechanism and the scissor lift mechanism. The weighing platform 923 is configured to weigh the fruits and vegetables inside the packaging bag as the packaging bag is moved above it by the scissor lift mechanism. The weighing platform 923 includes a base and at least one weighing sensor mounted below the base panel.

[0181] Specifically, the base is the main structural support component of the weighing platform 923. Its function is to provide a stable bearing surface to support the packaging bag to be weighed and the fruits and vegetables inside, and to provide a mounting base for the load cell. A load cell is a device that converts force or weight into a measurable electrical signal. Its working principle is generally based on the strain effect; that is, when subjected to pressure, the internal strain gauge deforms, causing a change in resistance, which in turn generates an electrical signal proportional to the applied force. In this embodiment, the load cell is mounted below the base panel. This mounting method allows the load cell to be effectively shielded and protected by the base structure, avoiding direct exposure to the external environment, thereby reducing the risk of damage caused by factors such as fruit and vegetable spillage, dust, moisture, or mechanical impact. Simultaneously, mounting the load cell below the base panel ensures stable support of the entire weighing area and accurate sensing of the vertical load acting on it. The configuration of at least one load cell allows for flexible selection based on the weighing range, accuracy requirements, and platform size. For example, for a larger or higher-precision weighing platform 923, multiple load cells can be configured to improve overall stability and accuracy.

[0182] Combination Figures 34 to 37 The following example will provide a more detailed explanation of the above technical solution:

[0183] Imagine a leafy vegetable processing plant that needs to automate the processing of large quantities of freshly harvested spinach to meet market demand for pre-cleaned vegetables. This spinach typically contains soil, the roots need to be removed, and it requires washing and quantitative packaging before transportation and sale.

[0184] First, workers pour entire baskets of spinach into the dispensing platform 103 of the sorting mechanism 10 of the device. The power module 104 on the dispensing platform 103 drives the pusher plate 102 to push the stacked spinach into the inlet one by one or in small batches. For example, the pusher plate 102 can reciprocate at a preset frequency and stroke to ensure that the spinach can enter the conveying mechanism 20 in an orderly manner.

[0185] Subsequently, the conveying mechanism 20 begins operation. Its chain 203 moves cyclically along a first preset path, driving multiple baskets 30 to pass through the inlet sequentially. When a basket 30 passes through the inlet, spinach is loaded into it. As the chain 203 moves, the basket 30 conveys the spinach to the root-cutting mechanism.

[0186] At the root-cutting mechanism, when the basket 30 containing spinach reaches the preset position, the first scissor push module 42 pushes the spinach in the basket 30 forward, precisely aligning its roots with the cutting position of the gate module 41. The gate module 41 then quickly closes, cutting off the spinach roots to obtain individual spinach leaves. The cut roots can fall into the waste collection bin below.

[0187] After root cutting is completed, the conveying mechanism 20 continues to transport the basket 30 containing the blades to the primary cleaning mechanism 50. In the water circulation soil removal module of the primary cleaning mechanism 50, the water supply module provides clean water, and the first spray module sprays the blades in the basket 30 thoroughly. At the same time, multiple first brushes 506 contact the blade surface according to a second preset path (e.g., rotating and reciprocating) to remove the dirt and impurities attached to the blades. The cleaned blades are then transported to the drying module 511 for preliminary dehydration treatment, such as by blowing hot air to remove most of the moisture from the blade surface.

[0188] Next, the basket 30 continues its movement, reaching above the separation mechanism 60. At this point, the basket 30 is designed to flip, dumping the preliminarily washed and dried spinach leaves onto the primary conveyor module 601 of the separation mechanism 60. The primary conveyor module 601 can be a vibrating conveyor belt, which initially disperses the stacked leaves through vibration. The leaves fall from the primary conveyor module 601 to the secondary conveyor module 602 below. On the secondary conveyor module 602, a second brush 603 is configured to rotate in the opposite direction to the conveying direction of the secondary conveyor module 602. The second brush 603 prevents the stacked leaves from moving forward, and the secondary conveyor module 602 further separates the leaves into individual pieces and guides them orderly to the flipping and sorting mechanism 70.

[0189] After receiving a single blade, the flipping and sorting mechanism 70 rotates its first drive shaft 702 under the drive of the drive source, causing the lifting rod 706 and the bidirectional flipping plate 703 to flip bidirectionally. For example, if the blade needs to be adjusted in direction to adapt to subsequent vertical transportation, the bidirectional flipping plate 703 can flip it 90 degrees and send it into the transfer mechanism 80.

[0190] The transfer mechanism 80 includes two conveyor belts 801 assembled in a V-shape. When the blade enters the V-groove, the two conveyor belts 801 are driven by differential gears, causing the originally horizontally placed blade to gradually rotate during the transfer process, eventually changing to a vertical transport state. Simultaneously with the vertical transport of the blade, a secondary cleaning mechanism 604 installed above the transfer mechanism 80 performs a secondary spray cleaning on the blade, ensuring a higher level of cleanliness.

[0191] Finally, after being washed and dried twice, the individual leaves fall one by one into the quantitative packaging mechanism 90. The packaging bag buffer mechanism prepares the packaging bags in advance, and the scissor pusher mechanism grabs, opens, and moves the packaging bags below the leaf drop port. After the leaves fall into the packaging bags, the weighing platform 923 accurately weighs the leaves inside the packaging bags to ensure that the weight of each bag of spinach meets the preset standard. Then, the bags are sealed and packaged, completing the entire processing flow.

[0192] Through the above example, this vegetable processing device achieves fully automated and continuous processing from vegetable input to final packaging, effectively solving the problems of low efficiency, insufficient standardization, and unstable quality associated with traditional manual processing. The close cooperation between the various components forms a highly efficient and collaborative whole, ensuring the quality and efficiency of leafy vegetable processing.

[0193] Based on the above examples, the technical concept of this vegetable processing device demonstrates a significant technological contribution. In existing technologies, the pre-processing of leafy vegetables generally relies on manual labor, resulting in low operational efficiency, insufficient standardization, and difficulty in consistently controlling product quality. For example, manual root removal may result in incomplete root removal or damage to leaves, and manual washing is also difficult to ensure uniform and thorough cleaning.

[0194] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.

10. A processing method, characterized in that, The process, implemented using the vegetable processing apparatus as described in any one of claims 1-9, includes the following steps: S1. Pour the multiple varieties of vegetables to be processed into the sorting mechanism (10) at once. The sorting mechanism (10) can push multiple vegetables into the basket (30) one by one. S2. The chain (203) of the conveying mechanism (20) rotates, driving the basket (30) into the root cutting mechanism; when the basket (30) reaches the set position, the first scissor push module (42) pushes the vegetable close to the guillotine module (41), and the guillotine module (41) completes the root removal to obtain the leaves; S3. After the root cutting is completed, the chain (203) rotates to send the blade to the primary cleaning mechanism (50). The primary cleaning mechanism (50) performs preliminary cleaning and soil removal on the blade in the basket (30). The basket (30) moves to the drying module (511), and the drying module (511) dries the blade. S4. The chain (203) continues to rotate, the basket (30) flips over, and the leaves are tilted to the first-level conveyor module (601). The first-level conveyor module (601) disperses the stacked leafy vegetables into single leafy vegetables and drops them to the second-level conveyor module (602). The second brush (603) and the second-level conveyor module (602) move in opposite directions to prevent the stacked leaves from moving forward. The second-level conveyor module (602) sends the leaves into the flipping and sorting mechanism (70) in the form of single leaves. S5. The flipping and sorting mechanism (70) flips the single blade backward and enters the transfer mechanism (80); the transfer mechanism (80) turns the single blade 90°, and at the same time the secondary cleaning mechanism (604) cleans the single blade a second time. S6. After the individual leaves are dried, the leaves fall one by one into the quantitative packaging mechanism (90) for packaging and weighing.
