Description

Technical Field

[0001] This utility model relates to the technical field of egg liquid extraction equipment, and in particular to a fully automatic egg liquid shell breaking and extraction device. Background Technology

[0002] In the industrial production process of egg products, the non-destructive extraction of egg liquid is one of the core processes to ensure the efficiency of subsequent processing and product quality. The current mainstream egg liquid extraction process generally adopts the technical path of "puncture-negative pressure suction". The specific operation is as follows: after the extraction needle is accurately inserted into the eggshell, it is driven to move along the eggshell axis to a preset position near the bottom of the eggshell. Through negative pressure suction, the egg liquid inside the eggshell is completely extracted.

[0003] Chinese utility model patent application number 202320567225.X discloses an egg liquid extraction device. This patent includes a support base with two positioning rings slidably connected to its top. A limit plate and a support block are fixedly connected to the top of the support base. A touch sensor is fixedly connected to one side of the support block, and linkage rods are slidably connected to both sides of the support block. An active extraction chamber is located above the support base. A connecting rod is fixedly connected between the active extraction chamber and the linkage rods. A driving block is fixedly connected to the inner side of the connecting rod, and a driven judgment rod is slidably connected to the inner side of the driving block. Through the cooperation of the linkage rod and the driven judgment rod, when extracting egg liquid from eggs of different sizes, the puncture needle can always be positioned at the lowest point inside the egg. This avoids the phenomenon where some egg liquid cannot be extracted due to a large distance from the bottom of the shell, thus ensuring the effectiveness of the egg liquid extraction.

[0004] However, this patent also has the following drawbacks: First, the patent directly uses a puncture needle to simultaneously complete the eggshell piercing and egg liquid extraction operations. This integrated operation mode poses a significant risk of eggshell debris contamination, which can not only cause channel blockage and affect the extraction efficiency of egg liquid, but may also mix into the finished egg liquid, contaminating the purity of the egg liquid, and may even affect the quality of the finished egg products due to debris residue; Second, during long-term continuous operation, a small amount of egg liquid will inevitably remain on the inner wall of the puncture needle. The residual egg liquid may breed bacteria and deteriorate, causing cross-contamination of fresh egg liquid and seriously affecting the hygiene and safety of egg products. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide a fully automatic egg liquid shell breaking and extraction device, which adopts a dual-station separate layout for drilling and liquid extraction, solving the problem of broken shells being sucked into the liquid extraction needle. At the same time, a cleaning mechanism is added to ensure the cleanliness of the egg liquid and food hygiene and safety.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: The fully automatic egg liquid breaking and extraction device includes a stand, on which a lifting platform is slidably mounted vertically.

The liquid extraction mechanism includes a vertically arranged liquid extraction needle, the upper end of which is slidably mounted on a lifting platform, and a second buffer is installed between the liquid extraction needle and the lifting platform. A liquid extraction port is provided on the side wall of the lower end of the liquid extraction needle. A cleaning mechanism is also provided below the egg tray.

[0007] The following are further optimizations of the above technical solution by this utility model: A peristaltic pump is fixedly installed on the lifting platform, and the outlet at the top of the suction needle is connected to the inlet port of the peristaltic pump.

[0008] Further optimization: The drive mechanism includes a support platform and a drive motor fixedly installed on the support platform. The egg tray is rotatably installed on the top of the support platform, and the power output shaft of the drive motor is connected to the shaft of the egg tray.

[0009] Further optimization: The egg tray is provided with several egg grooves arranged in a ring at equal intervals, and the positions of the egg cover and the liquid extraction needle correspond to the positions of the egg grooves.

[0010] Further optimization: The cleaning mechanism includes a water tank for holding cleaning fluid, which is used to clean the aspiration needle.

[0011] Further optimization: The water tank is also equipped with a liquid level monitoring element.

[0012] Further optimization: The correcting and breaking mechanism includes a first fixed outer cylinder, a connecting middle cylinder, and a fixed inner rod, which are sequentially nested together from the outside to the inside. The first fixed outer cylinder is fixed on the lifting platform, and its upper end is fixedly assembled with the upper end of the fixed inner rod. The upper end of the connecting middle cylinder is slidably installed vertically inside the first fixed outer cylinder. The lower end of the connecting middle cylinder extends out of the first fixed outer cylinder and is fixedly connected to the correcting egg cover. The lower end of the fixed inner rod extends into the correcting egg cover and is fixedly connected to the breaking cone.

[0013] Further optimization: The first buffer component is disposed inside the first fixed outer cylinder and sleeved on the fixed inner rod, and the two ends of the first buffer component are respectively connected to the connecting middle cylinder and the first fixed outer cylinder.

[0014] Further optimization: The liquid extraction mechanism also includes a second fixed outer cylinder and a sliding inner rod sleeved together. The second fixed outer cylinder is fixed on the lifting platform. The upper end of the sliding inner rod is slidably installed inside the second fixed outer cylinder and extends out of the top of the second fixed outer cylinder. The lower end of the sliding inner rod extends out of the bottom of the second fixed outer cylinder. The liquid extraction needle is inserted through the inside of the sliding inner rod, and its two ends extend out of the two ends of the sliding inner rod respectively.

[0015] Further optimization: The second buffer is disposed inside the second fixed outer cylinder and sleeved on the sliding inner rod. The two ends of the second buffer are respectively connected to the inner wall of the second fixed outer cylinder and the sliding inner rod.

[0016] The present invention adopts the above technical solution and has the following beneficial effects: 1. The present invention adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. It adopts a separate layout of drilling and liquid extraction stations. After the egg completes the shell breaking operation at the drilling station, the shell fragments produced by drilling fall into the egg shell. During the process of transferring the egg from the drilling station to the liquid extraction station, the shell fragments have sufficient settling time and can settle to the bottom of the egg shell under their own gravity, thereby reducing the risk of the shell fragments being sucked into the liquid extraction needle from a spatial perspective.

[0017] 2. The extraction port on the extraction needle adopts a side-opening technical solution, abandoning the bottom-opening structure in traditional egg liquid extraction equipment. As the extraction needle descends and extends into the eggshell, the bottom of the extraction needle can exert a flexible pushing effect on the settling shell fragments, pushing the shell fragments away from the extraction needle. This achieves effective isolation between the shell fragments and the extraction port, preventing the shell fragments from being sucked into the extraction needle.

[0018] 3. The cleaning mechanism, which integrates a liquid extraction needle, allows the cleaning fluid to be drawn into the liquid extraction needle and peristaltic pump after each batch of egg liquid extraction is completed. This automatically cleans and disinfects the liquid extraction needle and corresponding pipelines, effectively avoiding the risk of contamination caused by egg liquid residue and ensuring the cleanliness of the egg liquid and food hygiene and safety.

[0019] 4. The egg straightening cover has a vertical allowance, which allows it to automatically straighten and position the eggs in the egg tray during its descent. It can adaptively adjust according to the actual size and swinging posture of the eggs, effectively avoiding the situation where the bottom of the egg straightening cover makes hard contact with the eggs, which would cause the eggshells to be crushed.

[0020] 5. The extraction needle is also equipped with a vertical movement margin, which can adaptively buffer and adjust its downward stroke. Even if there is mechanical positioning deviation or fluctuation in egg size, it can avoid the problem of piercing the bottom of the eggshell due to excessive descent of the extraction needle.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown in the figure, the fully automatic egg liquid breaking and extraction device includes a frame 1, on which a lifting platform 2 is slidably mounted vertically. The lifting platform 2 is driven to slide vertically by a lifting drive component 21.

[0026] In this embodiment, the lifting drive 21 can be a commercially available standardized linear drive device, such as the ZCVL series Z-axis automatic slide provided by MISUMI (China) Precision Machinery Trading Co., Ltd.

[0027] This series of slides adopts a ball screw transmission structure, which has the technical advantages of high positioning accuracy, strong operation stability and wide load adaptability. The vertical displacement of the lifting platform 2 can be precisely controlled by pulse signals, which fully meets the high precision requirements of displacement control in the eggshell piercing, egg liquid extraction and subsequent cleaning processes of this utility model. At the same time, its modular design structure facilitates quick assembly with the stand 1, and the matching drive control system supports seamless docking with the host computer, realizing the integrated control of the automated process.

[0028] In this embodiment, three slotted photoelectric switches 23 are arranged at intervals along the height direction on the vertical guide surface of the support frame 1, and their installation positions correspond one-to-one with the core process positions of the lifting platform 2. That is, the first slotted photoelectric switch 23 corresponds to the initial standby height of the lifting platform 2, the second slotted photoelectric switch 23 corresponds to the minimum height of the shell breaking and liquid extraction operation, and the third slotted photoelectric switch 23 corresponds to the cleaning and maintenance height of the liquid extraction needle 7.

[0029] Preferably, the lifting platform 2 is equipped with a shell-breaking mechanism and a liquid extraction mechanism.

[0030] In this embodiment, a dual-station layout for drilling and liquid extraction is adopted, which physically isolates the eggshell breaking operation from the negative pressure extraction operation of egg liquid in space.

[0031] The specific operating procedure is as follows: First, the egg is transported to the drilling station, where the uprighting and breaking mechanism completes the adaptive uprighting operation of the egg and the breaking operation of the top of the eggshell. During the drilling process, the eggshell fragments generated fall into the egg. After the drilling is completed, the egg is rotated and transported to the liquid extraction station. During this process, the eggshell fragments can obtain sufficient settling time and gradually gather towards the bottom area of ​​the eggshell under their own gravity.

[0032] When the eggs reach the extraction station, the broken shells have already sunk a certain distance and formed a clear spatial layer with the suction area of ​​the extraction needle 7. This significantly reduces the probability of the broken shells being sucked into the extraction needle 7 from a spatial perspective, thus effectively avoiding the problems of blockage of the extraction needle 7 or the extraction channel of the peristaltic pump 10 and contamination of the egg liquid caused by egg shell fragments. This improves the stability of the egg liquid extraction operation and the purity of the finished egg liquid.

[0033] Preferably, an egg tray 3 is provided directly below the lifting platform 2, and the egg tray 3 is driven to rotate by a drive mechanism.

[0034] In this embodiment, the egg tray 3 adopts an integrated circular tray structure, and the material is preferably high-strength aluminum alloy, which can be adapted to long-term high-frequency rotation operation and cleaning and disinfection process, and meets the strict hygiene standards of industrialized egg production.

[0035] Preferably, the egg-setting and hatching mechanism includes an egg-setting cover 4 and a hatching cone 5 disposed inside the egg-setting cover 4.

[0036] In this embodiment, the upright egg cover 4 adopts an integrated barrel-shaped structure with an open bottom.

[0037] Preferably, the perforating cone 5 is fixedly installed on the lifting platform 2, the upright egg cover 4 is slidably installed on the lifting platform 2 along the vertical direction, and a first buffer 6 is installed between the egg cover 4 and the lifting platform 2.

[0038] In this embodiment, the first buffer 6 can be a commercially available standard compression spring. The core technical parameters of this type of compression spring, such as material selection, elastic coefficient, free length and maximum compression, have all been verified through standardized production and can accurately match the performance requirements of this utility model device in terms of buffering energy absorption, reset and rebound during operation.

[0039] Preferably, the liquid extraction mechanism includes a vertically arranged liquid extraction needle 7.

[0040] In this embodiment, the extraction needle 7 adopts an integrated tubular structure with a hollow interior. Its inner diameter is precisely calculated to ensure smooth flow of egg liquid during negative pressure suction.

[0041] Meanwhile, the bottom of the aspiration needle 7 has a smooth, edgeless spherical surface.

[0042] Preferably, the upper end of the aspiration needle 7 is slidably mounted on the lifting platform 2 along the vertical direction, and a second buffer 8 is installed between the needle and the lifting platform 2.

[0043] In this embodiment, the second buffer 8 can be a commercially available standard compression spring. The core technical parameters of this type of compression spring, such as material selection, elastic coefficient, free length and maximum compression, have all been verified through standardized production and can accurately match the performance requirements of this utility model device in terms of buffering energy absorption, reset and rebound during operation.

[0044] Preferably, a suction port 9 is provided on the side wall at the lower end of the suction needle 7.

[0045] In this embodiment, the liquid extraction port 9 adopts a side-opening technical solution, abandoning the traditional bottom-opening structure, and forms a matching with the spherical surface structure at the bottom of the liquid extraction needle 7.

[0046] When the extraction needle 7 descends vertically and extends into the eggshell, the spherical surface at its end can exert a flexible pushing effect on the broken shells generated by the drilling, pushing the broken shells outward to the outer area of ​​the extraction port 9, thus achieving physical isolation between the broken shells and the extraction port 9, and preventing the problem of egg liquid contamination and blockage caused by the broken shells being sucked into the extraction needle 7 by negative pressure.

[0047] Preferably, a cleaning mechanism is also provided below the egg tray 3.

[0048] Preferably, a peristaltic pump 10 is fixedly installed on the lifting platform 2, and the liquid outlet at the top of the liquid extraction needle 7 is connected to the liquid inlet port of the peristaltic pump 10.

[0049] In this embodiment, the peristaltic pump 10 can be a commercially available standardized finished product, such as the 104KA quick-install OEM peristaltic pump produced by Chongqing Jieheng Peristaltic Pump Co., Ltd.

[0050] The fluid transport process of this peristaltic pump 10 is achieved only by squeezing the hose with the pump body rollers. The pumped medium has no direct contact with the internal mechanical structure of the pump body, which can fundamentally avoid contact contamination between egg liquid and pump body components, and meet the hygiene and safety requirements for egg product production.

[0051] Moreover, the peristaltic pump 10 specifically includes a pump body base, a motor, a roller assembly, a food-grade combination hose, and a quick-release pump, which are fixedly installed on the lifting platform 2. The liquid inlet end of the combination hose is sealed and connected to the hollow cavity of the liquid extraction needle 7 through a high-temperature resistant and negative-pressure resistant food-grade silicone hose, and its liquid outlet end is also connected to the next station (i.e., the downstream product production equipment) through a silicone hose.

[0052] During operation, the motor drives the roller assembly to rotate, and the periodic squeezing and releasing of the combined hose creates negative pressure suction, driving the egg liquid inside the eggshell to flow smoothly through the extraction needle 7 to the next station. The entire conveying process is pulse-free and leak-free, ensuring the continuity and stability of the egg liquid extraction operation.

[0053] Preferably, the driving mechanism includes a support platform 11 and a drive motor 12 fixedly installed on the support platform 11, the egg tray 3 is rotatably installed on the top of the support platform 11, and the power output shaft of the drive motor 12 is connected to the shaft of the egg tray 3.

[0054] In this embodiment, the bottom of the egg tray 3 is fixedly installed on a turntable. The turntable and the egg tray 3 are coaxially designed to ensure the accuracy of the switching of the eggs in the egg trough 13.

[0055] The power output shaft of the drive motor 12 is precisely connected to the turntable. During operation, the drive motor 12 drives the turntable to rotate at a constant speed, which in turn drives the egg tray 3 to rotate synchronously, thus realizing the orderly transfer of eggs between the drilling station and the liquid extraction station.

[0056] In this embodiment, the turntable serves to elevate the egg tray 3. Combined with the thickness of the turntable itself and the elevating plate, it forms a reasonable vertical spatial layout, effectively avoiding the drive motor 12 below. This prevents the eggs from colliding with the drive motor 12, which could cause the eggs to break or their placement to be seriously misaligned, thus affecting the next process.

[0057] Preferably, the egg tray 3 is provided with a plurality of egg grooves 13 arranged in a ring at equal intervals, and the positions of the egg cover 4 and the liquid extraction needle 7 correspond to the positions of the egg grooves 13.

[0058] In this embodiment, the egg slots 13 are arranged in a uniform circular array on the surface of the egg tray 3 with the center of the egg tray 3 as the center, which can form a full-round wrapping support and limit the eggs from the circumference.

[0059] Preferably, the cleaning mechanism includes a water tank 14 for holding cleaning fluid, and the cleaning fluid in the water tank 14 is used to clean the aspiration needle 7.

[0060] In this embodiment, the water tank 14 adopts an integrated tank structure with an open top. Its length and width are optimized to completely cover the working rotation range of the egg tray 3.

[0061] One end of the water tank 14 extends directly below the egg tray 3, making it easy for the liquid extraction needle 7 to be inserted into the water tank 14 and extract the cleaning liquid. A water supply faucet 22 is provided above the other end of the water tank. The water supply faucet 22 is connected to an external water source or a water tank storing cleaning liquid through a pipe, and can flexibly switch between two modes: clean water rinsing or disinfectant rinsing, according to actual cleaning needs.

[0062] After the extraction of egg liquid from each batch of eggs is completed, the water supply faucet 22 is turned on and sprays water or cleaning solution to fill the water tank 14 with cleaning solution. The lifting platform 2 drives the extraction needle 7 and other components down into the water tank 14, so that the lower end of the extraction needle 7 is inserted into the water tank 14. The part of the extraction needle 7 inserted into the eggshell is cleaned. At the same time, the extraction needle 7 uses negative pressure to draw the cleaning solution into the hollow channel inside the extraction needle 7 to rinse the extraction channel used for egg liquid extraction, thereby ensuring the hygiene and safety of this utility model.

[0063] Preferably, a liquid level monitoring element 15 is also provided in the water tank 14.

[0064] In this embodiment, the liquid level monitoring element 15 can be a commercially available standard liquid level sensor, such as the XM / XT-300 series continuous liquid level sensor manufactured by Gems Sensors and Controls.

[0065] This series of sensors adopts the capacitive measurement principle, and its probe is made of corrosion-resistant food-grade material, which can be directly immersed in the cleaning solution inside the water tank 14, effectively ensuring the stability and accuracy of long-term monitoring.

[0066] The egg-setting and hatching mechanism includes a first fixed outer cylinder 16, a connecting middle cylinder 17, and a fixed inner rod 18, which are sequentially nested together from the outside to the inside. The first fixed outer cylinder 16 is fixed on the lifting platform 2, and its upper end is fixedly assembled with the upper end of the fixed inner rod 18. The upper end of the connecting middle cylinder 17 is slidably installed vertically inside the first fixed outer cylinder 16. The lower end of the connecting middle cylinder 17 extends out of the first fixed outer cylinder 16 and is fixedly connected to the egg-setting cover 4. The lower end of the fixed inner rod 18 extends into the egg-setting cover 4 and is fixedly connected to the hatching cone 5.

[0067] The first buffer 6 is disposed inside the first fixed outer cylinder 16 and sleeved on the fixed inner rod 18. The two ends of the first buffer 6 are respectively connected to the connecting middle cylinder 17 and the first fixed outer cylinder 16.

[0068] In this embodiment, the connection structure between the upright egg cover 4 and the lifting platform 2 is provided with a vertical movement margin.

[0069] For larger eggs, the egg straightening cover 4 can retract upwards to cushion the contact pressure of its bottom on the egg; for smaller eggs or eggs that are placed at a slight tilt, the egg straightening cover 4 can naturally descend to a position that fits against the egg.

[0070] This design effectively avoids rigid collisions and hard contact between the bottom of the egg cover 4 and the eggshell, greatly reducing the risk of the eggshell breaking due to excessive local pressure. It ensures that the egg maintains a stable posture during subsequent drilling and liquid extraction operations, providing a reliable guarantee for the smooth progress of the entire egg liquid extraction process.

[0071] Preferably, the liquid extraction mechanism further includes a second fixed outer cylinder 19 and a sliding inner rod 20 sleeved together. The second fixed outer cylinder 19 is fixed on the lifting platform 2. The upper end of the sliding inner rod 20 is slidably installed inside the second fixed outer cylinder 19 and extends out of the top of the second fixed outer cylinder 19. The lower end of the sliding inner rod 20 extends out of the bottom of the second fixed outer cylinder 19. The liquid extraction needle 7 is inserted through the sliding inner rod 20 and its two ends extend out of the two ends of the sliding inner rod 20, respectively.

[0072] Preferably, the second buffer member 8 is disposed inside the second fixed outer cylinder 19 and sleeved on the sliding inner rod 20, and the two ends of the second buffer member 8 are respectively connected to the inner wall of the second fixed outer cylinder 19 and the sliding inner rod 20.

[0073] In this embodiment, a vertical movement margin is reserved between the aspiration needle 7 and the lifting platform 2.

[0074] When mechanical positioning accuracy deviation occurs during operation, or when the size of individual eggs fluctuates, the liquid extraction needle 7 can achieve buffering through its own slight retraction after contacting the bottom of the eggshell, avoiding the situation where the bottom of the eggshell is directly punctured due to excessive downward stroke, thereby eliminating problems such as egg liquid leakage and shell contamination caused by "over-puncture".

[0075] The specific procedure for breaking eggs and extracting egg liquid using this invention is as follows: The first step is for the operator to place the eggs to be processed one by one into the egg slots 13 on the egg tray 3 to achieve initial positioning of the eggs; The second step is that the lifting drive component 21 drives the lifting platform 2 to descend at a constant speed. During the descent, the egg straightening cover 4 contacts the egg before the cracking cone 5, and its bottom opening precisely covers the top of the egg. Through its inner wall, it performs an all-round automatic straightening operation on the egg to correct any tilting posture that the egg may have. Third, as the lifting platform 2 continues to descend, the egg generates an upward reaction force on the bottom of the egg straightening cover 4, and with the help of the movable margin of the egg straightening cover 4, the egg straightening cover 4 moves slightly upward to achieve flexible avoidance. In the fourth step, the lifting platform 2 continues to descend to the lowest point of the preset hole-breaking operation, and straightens the hole-breaking cone 5 inside the egg cover 4 to accurately act on the center position of the top of the egg. The pointed end at the bottom squeezes the center position of the top of the eggshell to achieve a fixed-point hole in the top of the egg, and breaks the size of the hole in the top of the eggshell to the size that the liquid extraction needle 7 can pass through. At the same time, the small shell fragments generated by the hole fall directly into the egg under the action of gravity. Fifth step: After the hole-breaking process is completed, the lifting drive 21 drives the lifting platform 2 to move upward and return to its original position, straightening the egg cover 4, the hole-breaking cone 5 and the liquid extraction needle 7 and simultaneously raising them back to their initial height. Then the drive motor 12 starts, driving the egg tray 3 to rotate precisely around the axis by one hole, so that the eggs that have been broken are transferred to the area directly below the liquid extraction needle 7, and at the same time, the next egg to be processed is sent to the area directly below the straightening egg cover 4. Step 6: The lifting drive component 21 drives the lifting platform 2 to descend at a constant speed. At this time, the device enters the dual-station synchronous operation state: the egg straightening cover 4 on one side straightens the newly positioned egg and the breaking cone 5 performs the breaking operation; the liquid extraction needle 7 on the other side descends and smoothly inserts into the eggshell to the preset depth through the opening at the top of the already broken egg. Step 7: After the liquid extraction needle 7 is inserted into place, the peristaltic pump 10 starts and forms a stable negative pressure in the hollow channel inside the liquid extraction needle 7. Under the suction of the negative pressure, the egg liquid enters the channel through the liquid extraction port 9 opened on the side of the liquid extraction needle 7, and is then transported to the next station through the hose. Step 8: After the egg liquid extraction of the current egg is completed and the new egg breaking operation is completed, the peristaltic pump 10 stops and repeats steps 4 to 7 to achieve continuous egg breaking and egg liquid extraction of multiple eggs until the operation of a batch of eggs is completed. Step 9: After a batch of operations is completed, the lifting drive 21 drives the lifting platform 2 to descend to the lowest position, and the liquid extraction needle 7 passes through the corresponding egg tank 13 and is inserted into the water tank 14. Then the water supply faucet 22 is turned on, and cleaning fluid is injected into the water tank 14 through the external water pipe or cleaning fluid tank to prepare for cleaning the egg liquid extraction channel. Step 10: When the liquid level monitoring element 15 detects that the cleaning liquid level in the water tank 14 has reached the preset maximum level, it immediately sends a signal, the water supply faucet 22 stops supplying water, and then the peristaltic pump 10 starts again, drawing the cleaning liquid in the water tank 14 through the liquid extraction needle 7, the combined hose and other entire egg liquid conveying channels to thoroughly rinse the residual egg liquid inside. In the eleventh step, when the liquid level monitoring element 15 detects that the liquid level of the cleaning fluid in the water tank 14 has reached the preset minimum position, the peristaltic pump 10 is triggered to stop, the lifting drive component 21 drives the lifting platform 2 to move upward and return to its original position, the liquid extraction needle 7 is disengaged from the water tank 14, and the entire device is restored to the initial standby state, so that the next batch of eggs can be started at any time for shell breaking and egg liquid extraction.

[0076] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
