Description

Technical Field

[0001] The invention relates to the technical field of salted duck egg cleaning, and in particular to an automatic cleaning device and method for pickling salted duck eggs. Background Art

[0002] The production of salted duck eggs has a long history and first appeared in southern China. Traditional salting techniques usually use natural salting or liquid salting, which rely on the penetration of salt and water. After a certain period of time, the water inside the duck eggs is discharged, and the salt penetrates into the eggshell, making the egg yolk fragrant and the egg white hard, forming a unique salty taste.

[0003] In the process of salted duck egg pickling, the outer surface of the duck egg needs to be cleaned, and a cleaning device is one of the indispensable devices. Most of the cleaning devices for salted duck eggs on the market cannot use a flexible push method, cannot avoid mechanical hard extrusion or collision, and cannot provide good protection for the eggshell; therefore, an automatic cleaning device and method for salted duck egg pickling are proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automatic cleaning device and method for pickling salted duck eggs.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The invention discloses an automatic cleaning device for pickling salted duck eggs, comprising a cleaning unit and a washing unit, wherein one end of the washing unit is connected to the cleaning unit, and the cleaning unit comprises an inspection mechanism and an air intake mechanism installed on an inner end wall of one side of the inspection mechanism, a lifting mechanism is vertically arranged at the bottom of the inspection mechanism, and a connecting mechanism is horizontally interlaced in the middle of the inspection mechanism; the salted duck eggs to be cleaned are placed at the top position of the inner end wall of the inspection mechanism, because the top position of the inspection mechanism is arranged as an inner buckle structure, the salted duck eggs placed there are wrapped and protected by the inspection mechanism and the top of the air intake mechanism, and the staff can directly visually observe the outer surface of the salted duck eggs to check whether there are defects or stains on the outer surface of the salted duck eggs, thereby improving the efficiency and accuracy of the detection, simplifying the detection process before cleaning by optimizing the placement structure, reducing unnecessary operation steps, and improving the overall work efficiency;

[0007] The lifting mechanism comprises a mounting tube and a first assembly plate mounted on the bottom of the mounting tube, a lifting rod is arranged in an annular array on the lower end surface of the first assembly plate, and the other end of the lifting rod is connected to the second assembly plate; a positioning plate is arranged to cover the entire assembly ring from above, and the bottom of the salted duck egg is received through the middle cavity position of the positioning plate, and after the received salted duck egg completes the gas cleaning by the air intake mechanism, the staff will turn the salted duck egg that still needs to be cleaned again, and pass it through the inner cavity of the positioning plate and the assembly ring and then enter the inner cavity of the mounting tube, and connect the lifting rod through an external motor, and the distance between the first assembly plate and the lifting rod can be changed by adjusting the contraction degree of the lifting rod. In the process of the duck eggs falling vertically downward, the buffer mechanism will block the salted duck eggs from falling, and the protruding soft balls will softly stop the end faces of the salted duck eggs inward, playing a buffering and protective role in the falling process of the salted duck eggs, preventing the salted duck eggs from being damaged by impact due to rapid falling, and the limiting wrapping ring can also catch the fallen salted duck eggs. The limiting wrapping ring will slowly expand outward due to the weight of the salted duck eggs themselves, so that the fallen salted duck eggs will slowly pause in the buffer mechanism for a moment and then fall to the top of the conveying mechanism. Through the multi-level structure and automatic adjustment design, the complexity and error of manual operation are reduced, making the cleaning process more efficient and faster, while ensuring the cleaning quality.

[0008] The cleaning unit also includes a buffer mechanism installed on the inner cavity wall of the second assembly disk, the buffer mechanism includes a transverse protrusion and a protruding soft ball installed on one end of the transverse protrusion, ear blocks are arranged on both sides of the outer end wall of the transverse protrusion, and the two ends of the limiting wrapping ring are connected to one end of the adjacent ear blocks to form two groups of transverse protrusions, so that the two groups of transverse protrusions are combined into a whole.

[0009] Preferably, the inspection mechanism comprises a holding tray and lifting plates installed on both sides of the edge of the upper end surface of the holding tray, a through hole is provided in the middle position of the lifting plate, a carrying tray is arranged on the top of the holding tray, and a guide plate is arranged on one side of the other edge of the upper end surface of the holding tray, the salted duck eggs after inspection are taken out and placed just above the holding tray, the bottom of the salted duck eggs contacts the carrying tray, and the salted duck eggs themselves are limited and protected by the provided lifting plates and guide plates, so as to form a supporting and fixing effect from multiple angles, thereby further improving the stability of placement. Since most salted duck eggs are irregular ellipsoids, the two sets of holding plates provided The interval between the trays can be clamped and limited with one end of the salted duck egg, and at this time, the other end of the salted duck egg will directly touch the side end surface of the guide plate and the air intake mechanism, so that the salted duck egg is kept in the inner cavity of the inspection mechanism to avoid rolling or sliding due to its irregular ellipsoidal shape. The irregular shape of the salted duck egg is fully considered to avoid the salted duck egg being damaged by movement or external force during the handling process, and the protection is enhanced. The design enables the staff to easily remove the salted duck egg and stably place it in the inner cavity of the inspection mechanism without the need for additional fixing devices or complicated operations, thereby improving the convenience of use and work efficiency.

[0010] Preferably, the inspection mechanism further comprises an inner limiting ring arranged around the inner cavity wall of the carrier plate, the middle position of the outer end of the inner limiting ring is arranged as a protruding structure, the air intake mechanism comprises an air box and a transparent cavity arranged transversely on the side end face of the air box, air flow disrupting members are arranged on both sides of the inner cavity wall of the transparent cavity, a vent pipe is inserted into the inner cavity of the transparent cavity at the top position of the air box, the vent pipe is externally connected to a gas conveying device, and gas can be conveyed to the inner cavity of the vent pipe, the gas enters the gap between the transparent cavity and the two groups of air flow disrupting members, and is discharged from the inner cavity of the air box from the other end of the transparent cavity, and the discharged gas is used to spray gas on the outer surface of the salted duck egg in the flat placement stage;

[0011] The injected gas can effectively remove dust, impurities, dirt or excess salt crystals attached to the outer surface of the salted duck eggs. For hard-to-reach concave and convex areas, the gas jet can perform deep cleaning to ensure a cleaner surface. If there is residual moisture or liquid on the outer surface of the salted duck eggs, the high-speed gas flow can accelerate the evaporation of the moisture and make it dry quickly. If there are loose shell membranes or other attachments on the surface of the salted duck eggs, the gas jet can easily peel off these materials without damaging the eggshell. Compared with mechanical cleaning, gas jetting is gentler and will not scratch or crack the eggshell, thereby reducing the risk of damage. The gas used for the jet carries appropriate disinfectants or antibacterial gases to perform preliminary sterilization on the surface of the eggshell, thereby extending the shelf life of the salted duck eggs.

[0012] Preferably, the airflow disruptor includes a first splicing body and a second splicing body alternately arranged in the first splicing body, and an inner hollow cavity is provided at the interval between the first splicing body and the second splicing body. When the gas moves in the inner cavity of the transparent cavity, it contacts the first splicing body, the second splicing body and the inner hollow cavity, because the gaps between the three are small, the airflow contacts the inner cavity wall, which causes airflow turbulence. The airflow turbulence can produce irregular high-pressure airflow impacts, and the attachments on the surface of the salted duck eggs are washed at multiple angles, so that the cleaning effect is more comprehensive. The formation of turbulence enables the gas to be scattered in the inner cavity, covering more surface areas. , thereby improving the uniformity of processing and ensuring that there are no dead corners in cleaning or drying. The turbulence of the airflow changes the flow rate and direction, which helps to break the inertia of the gas layer and make the kinetic energy of the gas act more fully on the target surface, thereby improving the efficiency of gas processing. The energy dissipation caused by the turbulent airflow increases, which will cause a certain pressure loss, thereby slightly increasing the energy consumption required for gas transportation. The nonlinear pressure and velocity fluctuations of the turbulent flow can form a strong instantaneous impact force, which increases the ability to strip surface attachments. The turbulent flow will have a slight effect on the eggshell surface similar to "airflow polishing", making the cleaned eggshell smoother and cleaner, and improving the appearance quality.

[0013] Preferably, the connecting mechanism includes a positioning plate and an assembly ring sleeved on the inner cavity of the positioning plate, liquid inlet boxes are transversely arranged on both sides of the outer end surface of the assembly ring, liquid inlet pipes are arranged on the upper end surface of the liquid inlet box, and a liquid discharge mechanism is transversely arranged on the other side of the outer end surface of the assembly ring.

[0014] Preferably, the liquid discharge mechanism includes a guide cross member and a water tank installed at the bottom of the guide cross member, and a water spray pipe is arranged on the lower end surface of the water tank. At this time, the salted duck eggs that fall on the top of the conveying mechanism can be discharged from the bottom of the water spray pipe after clean water is transported to the inner cavity of the liquid inlet pipe, so that the clean water passes through the liquid inlet cross box, the assembly ring, the guide cross member and the inner cavity of the water tank. The three groups of water spray pipes and the object moving groove are arranged in the same direction, and the output power of the three groups of water spray pipes is different. The water spray pipe on the side close to the lifting mechanism has the largest output power, providing strong flushing to remove more stubborn stains; and the power on the side away from the lifting mechanism gradually decreases, providing a softer flushing, avoiding excessive impact on the shell of the salted duck egg, protecting the integrity of the eggshell, and when the clean water is discharged from the water spray pipe, it directly flushes the salted duck eggs placed above the cleaning unit.

[0015] Preferably, the cleaning unit comprises a conveying mechanism and a drying and cleaning mechanism installed just above the conveying mechanism, the conveying mechanism comprises two sets of conveying racks arranged opposite to each other and a water outlet trough opened on the inner end surface of the conveying rack, an object moving trough is arranged above the water outlet trough, and the salted duck eggs falling into the inner cavity of the conveying rack are initially in a vertical state, and the duck eggs initially fall vertically and contact the inner cavity wall of the conveying rack and then fall down, and the movement of the salted duck eggs is naturally guided by gravity and contact force, without the need for additional mechanical structure, thus simplifying the design, and because the object moving trough is arranged in a wave shape, the salted duck eggs will roll to the wave protruding part of the object moving trough, and the objects The wavy design of the object moving groove enables the salted duck eggs to roll to the wavy protruding parts and stabilize at a predetermined position, ensuring that the clean water can concentrate on the key parts of the salted duck eggs and enhance the cleaning effect. Moreover, because the wavy protruding parts of the object moving groove are all located on the right side of the corresponding water spray pipe above, the flexible pushing method of the wavy protruding parts and the clean water drive avoids mechanical hard squeezing or collision, forms a good protection for the eggshell, and reduces the breakage rate. When the water spray pipe sprays clean water downward, it will push the salted duck eggs into the drying and cleaning mechanism without rebounding; the clean water after cleaning will slide along the water outlet groove and be discharged from the inner cavity of the device.

[0016] Preferably, the drying and cleaning mechanism comprises a mounting shell and a built-in top frame mounted on the inner cavity of the mounting shell, a horizontal mounting shaft is arranged transversely interspersed on one side of the built-in top frame, and the transverse mounting shaft passes through the inner cavity of the blocking pad, so that the blocking pad can rotate around the built-in top frame with the transverse mounting shaft as a fulcrum, and mounting parts are arranged on the lower end surface of the built-in top frame, and brushes are arranged on the side end walls of two groups of oppositely arranged mounting parts. When the salted duck egg slides to one side and touches the blocking pad, the blocking pad can rotate with the transverse mounting shaft as a fulcrum, so that the inner cavity of the mounting shell is in an open state. This structure makes the cleaning process more flexible, ensuring that subsequent operations can be carried out smoothly after the salted duck egg is cleaned. The salted duck eggs are cleaned by the conveying mechanism, and the conveying mechanism pushes the salted duck eggs to move, ensuring that they pass through the brush intervals.

[0017] A method for an automatic cleaning device for pickling salted duck eggs, comprising the following steps:

[0018] S1: placing the salted duck eggs to be cleaned at the top of the inner end wall of the inspection mechanism, where the salted duck eggs are wrapped and protected by the inspection mechanism and the top of the air intake mechanism, so that the staff can directly visually observe the outer surface of the salted duck eggs to check whether there are defects or stains on the outer surface of the salted duck eggs;

[0019] S2: Take out the inspected salted duck eggs and place them directly above the serving tray, with the bottom of the salted duck eggs touching the serving tray, and the salted duck eggs themselves are protected by the provided lifting plates and guide plates, thereby forming a supporting and fixing effect from multiple angles;

[0020] S3: inserting a vent pipe into the inner cavity of the permeable cavity at the top position of the air box, the vent pipe is externally connected to a gas delivery device, and can deliver gas to the inner cavity of the vent pipe, the gas enters the interval between the permeable cavity and the two groups of airflow disruptors, and is discharged from the inner cavity of the air box from the other end of the permeable cavity, and the discharged gas is used to spray gas on the outer surface of the salted duck egg in the flat placement stage;

[0021] S4: The injected gas can effectively remove dust, impurities, dirt or excess salt crystals attached to the outer surface of the salted duck eggs. If there is residual moisture or liquid on the outer surface of the salted duck eggs, the high-speed gas flow can accelerate the evaporation of moisture and make it dry quickly. If there are loose shell membranes or other attachments on the surface of the salted duck eggs, the gas jet can easily peel off these materials;

[0022] S5: When the gas moves in the permeable cavity and contacts the first splicing body, the second splicing body and the inner hollow cavity, the gaps between the three are small, and the airflow contacts the inner cavity wall, which causes airflow turbulence. The airflow turbulence can produce irregular high-pressure airflow impact, and wash the attachments on the surface of the salted duck egg at multiple angles.

[0023] S6: The positioning plate is set to cover the entire assembly ring from above, and the bottom of the salted duck egg is received through the middle cavity of the positioning plate. After the received salted duck egg completes the gas cleaning by the air intake mechanism, the staff will turn the salted duck egg that still needs to be cleaned again, and pass it through the inner cavity of the positioning plate and the assembly ring and then enter the inner cavity of the installation cylinder. The lifting rod is connected through an external motor, and the spacing between the first assembly plate and the lifting rod can be changed by adjusting the contraction degree of the lifting rod. When the salted duck egg falls vertically downward, the buffer mechanism will block the passing salted duck egg from falling, and the protruding soft ball will softly stop the end faces of both sides of the salted duck egg inward, and the falling salted duck egg will slowly pause in the buffer mechanism for a moment and then fall to the top of the conveying mechanism;

[0024] S7: At this time, the salted duck eggs dropped on the conveying mechanism can be discharged from the bottom of the water spray pipe by conveying clean water to the inner cavity of the liquid inlet pipe, so that the clean water passes through the liquid inlet horizontal box, the assembly ring, the guide cross piece and the inner cavity of the water storage tank. The three groups of water spray pipes and the object moving groove are arranged in the same direction, and the output power of the three groups of water spray pipes is different. The output power of the water spray pipe on the side close to the lifting mechanism is the largest, providing strong flushing to remove more stubborn stains, while the power on the side away from the lifting mechanism gradually decreases, providing a softer flushing to avoid excessive impact on the shell of the salted duck egg;

[0025] S8: The initial state of the salted duck eggs falling into the inner cavity of the conveyor rack is vertical falling. The duck eggs initially fall vertically and contact the inner cavity wall of the conveyor rack and then fall over. The movement of the salted duck eggs is naturally guided by gravity and contact force. Since the object moving groove is set in a wave shape, the salted duck eggs will roll to the wave protruding part of the object moving groove. The wave-shaped design of the object moving groove enables the salted duck eggs to roll to the wave protruding part and stabilize at a predetermined position, ensuring that clean water can concentrate on the key parts of the salted duck eggs and enhance the cleaning effect.

[0026] S9: When the salted duck eggs slide to one side and touch the blocking pad, the blocking pad can rotate with the horizontal installation axis as the fulcrum, so that the inner cavity of the installation shell is in an open state. This structure makes the cleaning process more flexible, ensuring that subsequent operations can be carried out smoothly after the salted duck eggs are cleaned, avoiding jamming or blockage. The cleaned salted duck eggs will go along the gaps between the multiple groups of combined components formed by the arranged installation parts and the brushes, and due to the thrust in the transportation of the conveying mechanism, they will pass through the relatively set brush intervals. When the brushes on both sides touch the outer wall of the salted duck eggs, the brushes touch the outer wall of the salted duck eggs, effectively brushing away impurities and residual water on the surface of the salted duck eggs, ensuring thorough cleaning, and the device is discharged from one side of the installation shell, thereby achieving the purpose of cleaning the salted duck eggs.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The staff can directly observe the outer surface of the salted duck eggs visually to check whether there are any defects or stains on the outer surface of the salted duck eggs, which improves the efficiency and accuracy of the inspection. By optimizing the placement structure, the inspection process before cleaning is simplified, unnecessary operating steps are reduced, and the overall work efficiency is improved.

[0029] 2. Prevent the salted duck eggs from rolling or sliding due to their irregular ellipsoidal shape. The irregular shape of the salted duck eggs is fully considered to prevent the salted duck eggs from being damaged by movement or external force during the handling process, and enhance the protection. The design enables the staff to easily remove the salted duck eggs and place them stably in the inner cavity of the inspection mechanism without the need for additional fixing devices or complicated operations, thereby improving the convenience of use and work efficiency.

[0030] 3. Gas jetting strips these materials without scratching or cracking the eggshell, thus reducing the risk of damage. The jetted gas carries appropriate disinfectants or antibacterial gases to perform preliminary sterilization on the eggshell surface, thereby extending the shelf life of the salted duck eggs.

[0031] 4. When the gas moves in the transparent cavity and contacts the first splicing body, the second splicing body and the inner hollow cavity, the gap between the three is small, and the airflow contacts the inner cavity wall, which will cause airflow turbulence. The turbulent airflow can produce irregular high-pressure airflow impact, and the attachments on the surface of the salted duck eggs are washed at multiple angles, making the cleaning effect more comprehensive. The formation of turbulence enables the gas to be scattered in the inner cavity, covering more surface area, thereby improving the processing uniformity and ensuring that there are no dead corners in cleaning or drying. The turbulence of the airflow changes the flow velocity and direction, which helps to break the inertia of the gas layer, so that the kinetic energy of the gas can act more fully on the target surface, thereby improving the efficiency of gas treatment.

[0032] 5. Due to the increased energy dissipation caused by air turbulence, a certain pressure loss will be caused, which will slightly increase the energy consumption required for gas transportation. The nonlinear pressure and velocity fluctuations of turbulence can form a strong instantaneous impact force, increasing the ability to strip surface attachments. Turbulence will produce a slight effect similar to "air flow polishing" on the eggshell surface, making the cleaned eggshell smoother and cleaner, and improving the appearance quality.

[0033] 6. The protruding soft balls will softly stop the two side end faces of the salted duck eggs inward, which plays a buffering and protective role in the process of the salted duck eggs falling, preventing the salted duck eggs from being impacted and damaged due to rapid falling. The limit wrapping ring can also catch the fallen salted duck eggs. The limit wrapping ring will slowly expand outward due to the weight of the salted duck eggs themselves, so that the fallen salted duck eggs will slowly pause in the buffer mechanism for a moment and then fall to the top of the conveying mechanism. The multi-level structure and automatic adjustment design reduce the complexity and errors of manual operation, making the cleaning process more efficient and faster while ensuring the cleaning quality.

[0034] 7. The three groups of water spray pipes are set in the same direction as the object moving trough, and the output power of the three groups of water spray pipes is different. The water spray pipes close to the lifting mechanism have the largest output power, providing strong flushing to remove stubborn stains; while the power on the side away from the lifting mechanism gradually decreases, providing softer flushing to avoid excessive impact on the shell of the salted duck eggs and protect the integrity of the eggshell. When the clean water is discharged from the water spray pipe, it directly flushes the salted duck eggs placed above the cleaning unit.

[0035] 8. The wavy design of the object moving groove makes the salted duck eggs roll to the wavy protrusions and stabilize at the predetermined position, ensuring that the clean water can concentrate on the key parts of the salted duck eggs and enhance the cleaning effect. Moreover, because the wavy protrusions of the object moving groove are all on the right side of the corresponding water spray pipe above, the wavy protrusions and the flexible pushing method driven by the clean water avoid mechanical hard extrusion or collision, thus forming a good protection for the eggshell and reducing the breakage rate. When the water spray pipe sprays clean water downward, the salted duck eggs will be pushed into the drying and cleaning mechanism without rebounding; the clean water after cleaning will slide along the water outlet trough and be discharged from the inner cavity of the device.

At this time, the other end of the salted duck egg will directly touch the guide plate 116 and the side end surface of the air intake mechanism 12, so that the salted duck egg is kept in the inner cavity of the inspection mechanism 11 to avoid rolling or sliding due to its irregular ellipsoidal shape. The irregular shape of the salted duck egg is fully considered to avoid the salted duck egg being damaged by movement or external force during the processing, thereby enhancing the protection. The design enables the staff to easily remove the salted duck egg and stably place it in the inner cavity of the inspection mechanism 11 without the need for additional fixing devices or complicated operations, thereby improving the convenience of use and work efficiency.

[0053] Embodiment 4, the inspection mechanism 11 also includes an inner limit ring 115 arranged around the inner cavity wall of the carrier plate 114, and the middle position of the outer end of the inner limit ring 115 is set as a protruding structure; the air intake mechanism 12 includes an air box 121 and a transparent cavity 122 arranged transversely on the side end surface of the air box 121, and air flow disruptors 123 are arranged on both sides of the inner cavity wall of the transparent cavity 122. A vent pipe is inserted into the inner cavity of the transparent cavity 122 at the top position of the air box 121. The vent pipe is externally connected to a gas delivery device, which can deliver gas to the inner cavity of the vent pipe. The gas enters the gap between the transparent cavity 122 and the two groups of air flow disruptors 123, and is discharged from the inner cavity of the air box 121 from the other end of the transparent cavity 122. The discharged gas is used to spray gas on the outer surface of the salted duck egg in the flat placement stage;

[0054] Example 5: The injected gas can effectively remove dust, impurities, dirt or excess salt crystals attached to the outer surface of the salted duck eggs. For the hard-to-reach concave-convex areas, the gas injection can perform deep cleaning to ensure that the surface is cleaner. If there is residual moisture or liquid on the outer surface of the salted duck eggs, the high-speed gas flow can accelerate the evaporation of the moisture and make it dry quickly. If there are loose shell membranes or other attachments on the surface of the salted duck eggs, the gas injection can easily peel off these materials without damaging the eggshell. Compared with mechanical cleaning, gas injection is gentler and will not scratch or crack the eggshell, thereby reducing the risk of damage. The injected gas carries appropriate disinfectants or antibacterial gases to perform preliminary sterilization on the eggshell surface, thereby extending the shelf life of the salted duck eggs.

[0055] Embodiment 6, the air flow disruptor 123 includes a first splicing body 1231 and a second splicing body 1232 alternately arranged in the first splicing body 1231, and an inner hollow cavity 1233 is provided at the interval between the first splicing body 1231 and the second splicing body 1232. When the gas moves in the inner cavity of the transparent cavity 122, it contacts the first splicing body 1231, the second splicing body 1232 and the inner hollow cavity 1233, because the gaps between the three are small, when the air flow contacts the inner cavity wall, it will cause air flow turbulence. The air flow turbulence can produce irregular high-pressure air flow impact, and the attachments on the surface of the salted duck eggs are washed at multiple angles, so that the cleaning effect is more comprehensive, and the formation of turbulence enables the gas to It is in a scattered state in the inner cavity, covering more surface area, thereby improving the processing uniformity and ensuring that there are no dead corners in cleaning or drying. The turbulence of the airflow changes the flow velocity and direction, which helps to break the inertia of the gas layer and make the kinetic energy of the gas act more fully on the target surface, improving the efficiency of gas treatment. The energy dissipation is aggravated due to the turbulent airflow, which will cause a certain pressure loss, thereby slightly increasing the energy consumption required for gas transportation. The nonlinear pressure and velocity fluctuations of the turbulent flow can form a strong instantaneous impact force, increasing the ability to strip surface attachments. The turbulent flow will have a slight effect on the eggshell surface similar to "airflow polishing", making the cleaned eggshell smoother and cleaner, improving the appearance quality.

[0056] In embodiment 7, the connecting mechanism 15 includes a positioning plate 151 and an assembly ring 152 which is sleeved on the inner cavity of the positioning plate 151, and liquid inlet boxes 153 are arranged horizontally on both sides of the outer end surface of the assembly ring 152, and liquid inlet pipes 154 are arranged on the upper end surface of the liquid inlet box 153, and a liquid discharge mechanism 155 is arranged horizontally on the other side of the outer end surface of the assembly ring 152.

[0057] Embodiment 8, the liquid discharge mechanism 155 comprises a guide cross member 1551 and a water storage tank 1552 installed at the bottom of the guide cross member 1551, and a water spray pipe 1553 is arranged on the lower end surface of the water storage tank 1552. At this time, the salted duck eggs dropped on the conveying mechanism 21 can be discharged from the bottom of the water spray pipe 1553 by conveying clean water to the inner cavity of the liquid inlet pipe 154, so that the clean water passes through the liquid inlet cross box 153, the assembly ring 152, the guide cross member 1551 and the inner cavity of the water storage tank 1552. The three groups of water spray pipes 15 53 is set in the same direction as the object moving groove 213, and the output powers of the three groups of water spray pipes 1553 are different. The water spray pipes 1553 on the side close to the lifting mechanism 13 have the largest output power, providing strong flushing to remove more stubborn stains; while the power on the side away from the lifting mechanism 13 gradually decreases, providing softer flushing to avoid excessive impact on the salted duck egg shell and protect the integrity of the eggshell. When the clean water is discharged from the water spray pipes 1553, it directly flushes the salted duck eggs placed above the cleaning unit 2.

[0058] Embodiment 9, the cleaning unit 2 includes a conveying mechanism 21 and a drying and cleaning mechanism 22 installed just above the conveying mechanism 21, the conveying mechanism 21 includes two sets of conveying racks 211 arranged opposite to each other and a water outlet trough 212 opened on the inner end surface of the conveying rack 211, an object moving trough 213 is arranged above the water outlet trough 212, and the salted duck eggs falling into the inner cavity of the conveying rack 211 are initially in a vertical state, and the duck eggs initially fall vertically and contact the inner cavity wall of the conveying rack 211 and then fall down, and the movement of the salted duck eggs is naturally guided by gravity and contact force, without the need for an additional mechanical structure, thereby simplifying the design, and because the object moving trough 213 is arranged in a wave shape, the salted duck eggs will roll to the wave shape of the object moving trough 213 The wavy design of the object moving groove 213 makes the salted duck eggs roll to the wavy protruding part and stabilize at a predetermined position, ensuring that the clean water can concentrate on the key parts of the salted duck eggs and enhance the cleaning effect. Moreover, because the wavy protruding parts of the object moving groove 213 are all on the right side of the corresponding water spray pipe 1553 above, the wavy protruding parts and the flexible pushing mode driven by the clean water avoid mechanical hard squeezing or collision, thus forming a good protection for the eggshell and reducing the breakage rate. When the water spray pipe 1553 sprays clean water downward, the salted duck eggs will be pushed into the drying and cleaning mechanism 22 without rebounding; the clean water after cleaning will slide along the water outlet groove 212 and be discharged from the inner cavity of the device.

[0059] Embodiment 11, the drying and cleaning mechanism 22 includes a mounting shell 226 and a built-in top frame 221 mounted on the inner cavity of the mounting shell 226, a horizontal mounting shaft 222 is arranged transversely on one side of the built-in top frame 221, and the transverse mounting shaft 222 passes through the inner cavity of the blocking pad 223, so that the blocking pad 223 can rotate around the built-in top frame 221 with the transverse mounting shaft 222 as a fulcrum, and the lower end surface of the built-in top frame 221 is arranged with mounting parts 224, and the side end walls of the two groups of relatively arranged mounting parts 224 are both provided with brushes 225. When the salted duck egg slides to one side and touches the blocking pad 223, the blocking pad 223 can rotate with the transverse mounting shaft 222 as a fulcrum, so that the inner cavity of the mounting shell 226 is in an open state. This structure makes the cleaning process more flexible and ensures that the salted duck egg is cleaned in a clean state. After washing is completed, subsequent operations can be carried out smoothly to avoid jamming or blocking. The cleaned salted duck eggs will be along the gaps between the multiple groups of combined components formed by the arranged mounting parts 224 and the brushes 225, and due to the thrust in the transportation of the conveying mechanism 21, they will pass through the intervals between the relatively arranged brushes 225. When the brushes 225 on both sides touch the outer wall of the salted duck eggs, the brushes 225 touch the outer wall of the salted duck eggs to effectively brush away impurities and residual clean water on the surface of the salted duck eggs, ensuring thorough cleaning. The device is discharged from one side of the mounting shell 226, thereby achieving the effect of cleaning the salted duck eggs, and the transportation mechanism of the conveying mechanism 21 pushes the salted duck eggs to move, ensuring that they pass smoothly through the intervals between the brushes 225, while promoting the smooth operation of the equipment, achieving the continuity of the cleaning process, without the need for pauses, and greatly improving production efficiency.

[0060] A method for an automatic cleaning device for pickling salted duck eggs, comprising the following steps:

[0061] S1: placing the salted duck eggs to be cleaned at the top of the inner end wall of the inspection mechanism 11, where the salted duck eggs are wrapped and protected by the inspection mechanism 11 and the top of the air intake mechanism 12, so that the staff can directly visually observe the outer surface of the salted duck eggs to check whether there are defects or stains on the outer surface of the salted duck eggs;

[0062] S2: Take out the inspected salted duck eggs and place them directly above the serving tray 111, with the bottom of the salted duck eggs contacting the carrying tray 114, and the salted duck eggs themselves are limited and protected by the provided lifting plates 112 and guide plates 116, so as to form a supporting and fixing effect from multiple angles;

[0063] S3: inserting a vent pipe into the inner cavity of the transparent cavity 122 at the top position of the air box 121, the vent pipe is externally connected to a gas delivery device, and can deliver gas to the inner cavity of the vent pipe, the gas enters the interval between the transparent cavity 122 and the two groups of airflow disruptors 123, and is discharged from the inner cavity of the air box 121 from the other end of the transparent cavity 122, and the discharged gas is sprayed on the outer surface of the salted duck egg in the flat placement stage;

[0064] S4: The injected gas can effectively remove dust, impurities, dirt or excess salt crystals attached to the outer surface of the salted duck eggs. If there is residual moisture or liquid on the outer surface of the salted duck eggs, the high-speed gas flow can accelerate the evaporation of moisture and make it dry quickly. If there are loose shell membranes or other attachments on the surface of the salted duck eggs, the gas jet can easily peel off these materials;

[0065] S5: When the gas moves in the inner cavity of the permeable cavity 122 and contacts the first splicing body 1231, the second splicing body 1232 and the inner hollow cavity 1233, the gaps between the three are small, and the airflow contacts the inner cavity wall, which causes the airflow to be turbulent. The turbulent airflow can produce irregular high-pressure airflow impact, and the attached substances on the surface of the salted duck egg are washed at multiple angles.

[0066] S6: The positioning plate 151 is provided to cover the entire assembly ring 152 from above, and the bottom of the salted duck egg is received through the middle cavity position of the positioning plate 151. After the received salted duck egg completes the gas cleaning by the air intake mechanism 12, the staff will turn the salted duck egg that still needs to be cleaned again by 180 degrees, and pass it through the inner cavity of the positioning plate 151 and the assembly ring 152 and then enter the inner cavity of the installation cylinder 131, and connect the lifting rod 133 through an external motor. The spacing between the first assembly plate 132 and the lifting rod 133 can be changed by adjusting the contraction degree of the lifting rod 133. When the salted duck egg falls vertically downward, the buffer mechanism 14 provided will block the passing salted duck egg from falling, and the protruding soft ball 142 provided will softly stop the end faces of both sides of the salted duck egg inward, and the falling salted duck egg will slowly pause in the buffer mechanism 14 for a moment and then fall to the top of the conveying mechanism 21;

[0067] S7: At this time, the salted duck eggs dropped on the conveying mechanism 21 can be discharged from the bottom of the water spray pipe 1553 by conveying clean water to the inner cavity of the liquid inlet pipe 154, so that the clean water passes through the inner cavity of the liquid inlet horizontal box 153, the assembly ring 152, the guide cross member 1551 and the water storage tank 1552. The three groups of water spray pipes 1553 and the object moving groove 213 are arranged in the same direction, and the output power of the three groups of water spray pipes 1553 is different from each other. The water spray pipe 1553 on the side close to the lifting mechanism 13 has the largest output power, providing strong flushing to remove more stubborn stains, while the power on the side away from the lifting mechanism 13 gradually decreases, providing a softer flushing to avoid excessive impact on the shell of the salted duck egg;

[0068] S8: The initial state of the salted duck eggs falling into the inner cavity of the conveying rack 211 is vertical falling. The duck eggs initially fall vertically and contact the inner cavity wall of the conveying rack 211 and then fall down. The movement of the salted duck eggs is naturally guided by gravity and contact force. Since the object moving groove 213 is arranged in a wave shape, the salted duck eggs will roll to the wave protruding part of the object moving groove 213. The wave-shaped design of the object moving groove 213 makes the salted duck eggs roll to the wave protruding part and stabilize at a predetermined position, ensuring that the clean water can be concentrated on the key parts of the salted duck eggs to enhance the cleaning effect.

[0069] S9: When the salted duck eggs slide to one side and touch the blocking pad 223, the blocking pad 223 can rotate with the horizontal mounting shaft 222 as a fulcrum, so that the inner cavity of the mounting shell 226 is in an open state. This structure makes the cleaning process more flexible, ensuring that subsequent operations can be carried out smoothly after the salted duck eggs are cleaned, and avoiding jamming or blockage. The cleaned salted duck eggs will be along the gaps between the multiple groups of combined components formed by the arranged mounting parts 224 and the brushes 225, and due to the thrust in the transportation of the conveying mechanism 21, they will pass through the intervals between the relatively arranged brushes 225. When the brushes 225 on both sides touch the outer wall of the salted duck eggs, the brushes 225 touch the outer wall of the salted duck eggs, effectively brushing away impurities and residual clean water on the surface of the salted duck eggs, ensuring thorough cleaning, and the device is discharged from one side of the mounting shell 226, thereby achieving the purpose of cleaning the salted duck eggs.
