The sieve drum assembly 401 is a front-end one-way opening structure and is used for placing shellfish seafood. Sieve hole assemblies 4011 for the falling of shellfish meat are arranged in an annular array inside the sieve drum assembly 401, and a leg assembly 1013 is fixedly connected to the bottom end surface of the connecting plate 1012; By connecting the hood mechanism 3 to the top of the support mechanism 1, two rotating shaft mechanisms 4 are rotatably connected inside the hood mechanism 3 through bearing seats, and the front ends of the rotating shaft mechanisms 4 are connected to the sieve drum assemblies 401, and the sieve drum assemblies 401 are provided with sieve hole assemblies 4011. This structure builds the basic framework of the shelling device and provides the basic structural support for subsequent shelling and separating the shellfish meat from the shell. The sieve drum assembly 401 can accommodate shellfish seafood, and the sieve hole assemblies 4011 facilitate the separation of the shellfish meat by falling.

[0024] Refer to Figure 1 , Figure 5, a through groove is provided at the internal center position of the support mechanism 1, and a flow concentrator 101 is embedded in the through groove. The flow concentrator 101 is a frustum-shaped structure that is thicker at the top and thinner at the bottom. A drain pipe 1011 is fixedly connected to the bottom end surface of the flow concentrator 101. A side plate mechanism 5 is fixedly connected to the front end of the housing mechanism 3. A supply pipe 501 with a nozzle assembly 5011 is fixedly connected inside the side plate mechanism 5. An inlet pipe 5012 is fixedly connected to the front end surface of the supply pipe 501. An inlet flange 5013 is fixedly connected to the front end of the inlet pipe 5012. Connecting holes 5014 are arranged in an annular array inside the inlet flange 5013. The nozzle assembly 5011 is used for spraying water to impact the shellfish; The flow concentrator 101 is embedded in the through groove at the internal center of the support mechanism 1. The flow concentrator 101 is frustum-shaped and has a drain pipe 1011 connected to its bottom. This design can converge the water or other liquids generated during the shelling process into the flow concentrator 101 and discharge them through the drain pipe 1011, effectively solving the drainage problem during the shelling process and preventing liquid accumulation from affecting the operation of the equipment.

[0025] Refer to Figure 4 、 Figure 7 , the drain pipe 1011 is in communication with the flow concentrator 101, and the drain pipe 1011 and the flow concentrator 101 together form a drainage structure. A connecting plate 1012 is fixedly connected to the outside of the support mechanism 1, and there are four connecting plates 1012 in total; The drain pipe 1011 and the flow concentrator 101 are in communication to form a drainage structure, and four connecting plates 1012 are connected to the outside of the support mechanism 1. This structure not only ensures the integrity and effectiveness of the drainage system, but the connecting plates 1012 also provide connection points for installing other components, enhancing the stability of the overall structure of the equipment.

[0026] Refer to Figure 1 、 Figure 8 , every two longitudinally adjacent connecting plates 1012 form a group, and the two groups of connecting plates 1012 are respectively fixedly connected to the left and right side surfaces of the support mechanism 1. Guide roller mechanisms 2 are installed inside both groups of connecting plates 1012; Every two longitudinally adjacent connecting plates 1012 form a group and are respectively fixed on the left and right sides of the support mechanism 1. Guide roller mechanisms 2 are installed inside the two groups of connecting plates 1012. Such a layout provides support for installing the conveyor belt 2011 and facilitates subsequent driving of the conveyor belt 2011 by the guide roller mechanisms 2 for transporting the shellfish meat.

[0027] Refer to Figure 3 、 Figure 5 , a servo motor 201 is installed on the front end surface of the group of connecting plates 1012 on the left side. An output shaft is provided at the rear side of the servo motor 201, and the output shaft is connected to the guide roller mechanism 2 on the left side through a coupling; A servo motor 201 is installed at the front end of a set of connecting plates 1012 on the left side. Its output shaft is connected to the left roller mechanism 2 through a coupling. The servo motor 201 provides power for the roller mechanism 2, thereby driving the conveyor belt 2011 to move, realizing the automatic conveyance of shellfish meat, and improving the efficiency of collecting shellfish meat after shelling.

[0028] Refer to Figure 1 、 Figure 2 On the outer sides of the two roller mechanisms 2, a conveyor belt 2011 is also installed. The conveyor belt 2011 is used to convey shellfish meat, and through slots are linearly arranged inside the conveyor belt 2011. This through slot is a drainage groove 2012; By installing the conveyor belt 2011 on the outer sides of the two roller mechanisms 2, the conveyor belt 2011 is provided with a drainage groove 2012. The conveyor belt 2011 is used to convey shellfish meat, and the drainage groove 2012 can drain the residual moisture on the surface of the shellfish meat, avoiding the influence of moisture on the collection and storage of shellfish meat, and ensuring the quality of shellfish meat.

[0029] Refer to Figure 5 、 Figure 6 Inside the cover body mechanism 3, a through slot is opened. A closed window 301 is embedded inside this through slot. There are two closed windows 301 in total, and the two closed windows 301 are fixedly connected oppositely at the left and right side surfaces of the cover body mechanism 3, and two lighting lamps 3011 are fixedly connected linearly inside the cover body mechanism 3; By embedding two opposite closed windows 301 in the through slot inside the cover body mechanism 3, and fixedly connecting two lighting lamps 3011 inside. The closed window 301 can prevent the shell or other sundries of shellfish from splashing out to a certain extent during the shelling process, ensuring the safety of operators; the lighting lamps 3011 provide lighting for the shelling operation, facilitating the observation of the internal working conditions of the equipment.

[0030] Refer to Figure 2 、 Figure 8 On the rear side surface of the cover body mechanism 3, a driving motor 3013 is fixedly connected. An output shaft is provided at the front end of the driving motor 3013, and this output shaft is connected to the rotating shaft mechanism 4; By connecting the driving motor 3013 to the rear side surface of the cover body mechanism 3, its output shaft is connected to the rotating shaft mechanism 4. The driving motor 3013 provides power for the rotating shaft mechanism 4, enabling the sieve tube assembly 401 to rotate, realizing the shelling operation of shellfish seafood, and being one of the core power sources of the shelling device.

[0031] Refer to Figure 1 、 Figure 2 On the outer side of the rotating shaft mechanism 4, a transmission gear 3014 is also fixedly connected. The two transmission gears 3014 are meshed and transmitted together, and jointly form a transmission structure; The transmission structure is composed of the transmission gears 3014 on the outer sides of the two rotating shaft mechanisms 4 meshing with each other. This transmission structure can ensure the synchronous rotation of the two rotating shaft mechanisms 4, making the rotation speeds and directions of the two sieve drum assemblies 401 consistent, and improving the shelling efficiency and stability.

[0032] Refer to Figure 3 , Figure 6 , the cover mechanism 3 and the support mechanism 1 together form a shielding and protection structure for the sieve drum assembly 401 and are located outside the sieve drum assembly 401; The cover mechanism 3 and the support mechanism 1 form a shielding and protection structure for the sieve drum assembly 401, and the bottom of the connecting plate 1012 is connected to the leg assembly 1013. The shielding and protection structure can protect the sieve drum assembly 401 and the shellfish inside, reduce the interference of external factors, and the leg assembly 1013 supports the entire device to ensure the stable placement of the device.

[0033] During operation, first, place the shellfish dehulling device on the selected working site. The leg assembly 1013 plays a supporting role to ensure that the entire device is in a stable state, prevent shaking or tipping during operation, which may affect the normal operation and operation safety of the device. Check the connection parts of the device, such as the connection between the support mechanism 1 and the cover mechanism 3, the connection between the rotating shaft mechanism 4 and the sieve drum assembly 401, the connection between the guide roller mechanism 2 and the connecting plate 1012, etc., to ensure that all parts are firmly connected without looseness. After confirming that all parts of the device are normal, turn on the power supply to provide power for each power component of the device, such as the drive motor 3013 and the servo motor 201, to make it in a standby state; The operator puts the shellfish to be dehulled into the inside of the sieve drum assembly 401 one by one through the one-way opening at the front end of the sieve drum assembly 401. Since the sieve drum assembly 401 is fixed on the front end face of the rotating shaft mechanism 4 and is provided with a sieve hole assembly 4011 in an annular array inside, the put shellfish will perform shelling and shellfish meat separation operations in the sieve drum assembly 401 in the subsequent operations; Start the drive motor 3013. The front output shaft of the drive motor 3013 starts to rotate. This output shaft is directly connected to one of the rotating shaft mechanisms 4, driving this rotating shaft mechanism 4 to rotate together. Because the transmission gears 3014 are respectively fixedly connected to the outer sides of the two rotating shaft mechanisms 4 and these two transmission gears 3014 mesh with each other, when one rotating shaft mechanism 4 rotates, the meshing transmission gear 3014 will drive the other transmission gear 3014 to rotate, and then make the other rotating shaft mechanism 4 also rotate synchronously. Such a transmission structure ensures that the two rotating shaft mechanisms 4 rotate at the same speed and in the same direction of rotation, so that the two sieve drum assemblies 401 fixed to their fronts can also rotate synchronously and stably; As the sieve cylinder assembly 401 rotates at high speed, the shellfish placed therein are subjected to a strong centrifugal force. Driven by the centrifugal force, the shellfish continuously impact the inner wall of the sieve cylinder assembly 401. Since the shell of the shellfish is relatively brittle, it gradually breaks under continuous impact. The broken shellfish meat, due to its small volume and soft texture, will be thrown out of the sieve cylinder assembly 401 through the sieve hole assembly 4011 arranged in a circular array inside the sieve cylinder assembly 401 under the continuous action of the centrifugal force, realizing the preliminary separation of the shellfish meat from the shell. In this process, the shielding and protection structure jointly formed by the cover body mechanism 3 and the support mechanism 1 plays an important role. It effectively blocks the shell fragments and shellfish meat from splashing outwards, protecting the safety of the operator and avoiding the pollution of the working environment caused by material splashing; The shellfish meat thrown out from the sieve hole assembly 4011 directly falls on the conveyor belt 2011 below. At this time, the servo motor 201 is started, and the output shaft at the rear of the servo motor 201 starts to rotate. This output shaft is connected to the guide roller mechanism 2 on the left through a coupling, thereby driving the guide roller mechanism 2 on the left to rotate. Because the conveyor belt 2011 is installed on the outside of the two guide roller mechanisms 2, when the guide roller mechanism 2 on the left rotates, it will drive the conveyor belt 2011 to operate through friction. During the operation of the conveyor belt 2011, the shellfish meat falling on it is conveyed to the designated collection position, realizing the automatic collection of the shellfish meat. At the same time, through grooves are arranged in a straight array inside the conveyor belt 2011 as drainage grooves 2012. During the conveying process of the shellfish meat, the water remaining on the surface of the shellfish meat will be discharged through these drainage grooves 2012, avoiding the accumulation of water on the conveyor belt 2011, and further preventing the water from having an adverse impact on the quality of the shellfish meat, such as causing the shellfish meat to deteriorate or affecting its taste, etc.; During the whole process of shelling and shellfish meat collection, a certain amount of water will be generated inside the equipment. This water may come from the water carried by the shellfish itself, the liquid generated during the shelling process, etc. This water will gradually fall into the through groove opened at the central position inside the support mechanism 1, and the water collecting cover 101 embedded inside the through groove will receive this water. The water collecting cover 101 has a special upper thick and lower thin frustum structure. This structural design is beneficial to guiding the converged water to its bottom end. The drain pipe 1011 fixedly connected to the bottom end surface of the water collecting cover 101 is communicated with the water collecting cover 101. Under the action of gravity, the water flows into the drain pipe 1011 along the water collecting cover 101 and is finally discharged from the equipment through the drain pipe 1011, maintaining a dry environment inside the equipment and avoiding the influence of water accumulation on the normal operation of the equipment or causing the equipment components to rust and damage; During the operation of the device, the operator can turn on the lighting lamp 3011 inside the cover mechanism 3 according to the actual working environment and requirements. The lighting lamps 3011 are fixedly connected in a linear array inside the cover mechanism 3, and the light they emit can illuminate the working area inside the device, providing sufficient lighting for the shelling operation. At the same time, the closed windows 301 fixedly connected to both sides of the cover mechanism 3 can not only prevent material splashing to a certain extent but also provide a window for the operator to observe the inside of the device. The operator can observe the shelling situation of shellfish seafood in the sieve cylinder assembly 401 through the closed window 301 at any time, such as whether the shelling is thorough and whether the separation of the shellfish meat is normal, as well as the conveying situation of the shellfish meat on the conveyor belt 2011. Once it is found that the device is operating abnormally, the operator can promptly take corresponding measures for adjustment or treatment to ensure the stable operation of the device and the smooth progress of the shelling work.

[0034] In summary, by setting the sieve cylinder assembly 401, the device can quickly centrifuge and separate the shellfish shells and the shellfish meat.
