[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Automatic shelling of clams with high efficiency. The rotating motor drives the carrier plate and the crushing rod to rotate. After cleaning, the clams are transported downward through the telescopic tube. The crushing rod will crush the clams transported downward, so that the shells of the clams are broken for easy shelling. The broken clams fall on the carrier plate, and the carrier plate drives the filter screen and the follower plate to rotate at the same time. Due to the high-speed rotation of the carrier plate, a large centrifugal force is generated, and the meat in the clams will pass through the filter screen and be discharged from the discharge port.

[0016] 2. Clean the clams to prevent impurities from contaminating the shell and meat. The first vibration plate and the second vibration plate continue to move back and forth and then move relative to each other. More and more air and liquid are transported to the inside of the stirring shaft, so that the pressure gradually increases while the air and liquid are mixed. The air and liquid in the stirring shaft are sprayed onto the clams from the spray port on the brush, and the brush scrubs the surface of the clams. When the first vibration plate and the second vibration plate move back and forth, the first vibration plate and the second vibration plate simultaneously stretch the screen, so that the wrinkles on the screen are gradually flattened, and the screen drives the clams to move upward, turning the clams over, so as to facilitate cleaning of different positions of the clams, and through the scrubbing of the brush and the flushing of air and liquid, the cleaning effect of the clams is improved to prevent impurities from contaminating the shell and meat.

[0017] 3. High-temperature steam assists shelling to improve shelling efficiency. The metal plate cuts the magnetic flux lines in the magnetic field where the first and second electromagnets are energized, and current is generated in the metal plate and heat is generated. The metal plate transfers the heat to the heat-conducting medium, and the heat-conducting medium expands after absorbing the heat. The heat-conducting medium pushes the push plate to move toward the middle of the stirring shaft, and the push plate pulls the flexible film from a wrinkled state to a flat state. At this time, the heat-conducting medium transfers the heat to the air and liquid in the stirring shaft through the flexible film, so that the high-temperature air and liquid are sprayed on the surface of the clams, and the cleaned clams are steamed at high temperature to help the clams to be shelled and improve the shelling efficiency.

[0023] The stirring shaft 21 is hollow inside. A number of brushes 211 are arranged on the outer side of the stirring shaft 21. The number of brushes 211 are all communicated with the inside of the stirring shaft 21. A spraying port is formed on the brush 211 at one end away from the stirring shaft 21. A push plate 212 is slidably installed in the stirring shaft 21. A flexible film 213 and a return spring are connected between the push plate 212 and the stirring shaft 21. The return spring is located inside the flexible film 213. A number of folds are arranged on the flexible film 213. A heat-conducting medium 214 is arranged inside the flexible film 213. The heat-conducting medium 214 is a material that expands when heated. A number of metal plates are arranged on the flexible film 213. The metal plates are all in contact with the heat-conducting medium 214. The first vibrating plate 22 and the second vibrating plate 23 are both provided with a first electromagnet 215 and a second electromagnet 216. The metal plates are located in the magnetic fields of the first electromagnet 215 and the second electromagnet 216.

[0024] The greater the magnetic field intensity generated by the cooperation of the first electromagnet 215 and the second electromagnet 216, the greater the current generated by the metal plate cutting the magnetic induction line, the greater the heat generated by the metal plate, the greater the degree of expansion of the heat-conducting medium 214, and the greater the contact area between the flexible film 213 and the air and liquid. More air and liquid can be heated simultaneously. Therefore, the control system can adjust the magnetic field intensity of the first electromagnet 215 and the second electromagnet 216, and then realize the adjustment of the heating efficiency of the air and liquid to meet different usage occasions.

[0025] A number of folds are arranged on the screen 24. A telescopic tube 241 is connected between the screen 24 and the partition plate 111. The telescopic tube 241 is a flexible tube. The partition plate 111 is installed on the housing 11. A rotating motor 32 is installed on the housing 11. A carrier plate 33 and a crushing rod 36 are installed on the output shaft of the rotating motor 32. The crushing rod 36 is located above the carrier plate 33. The crushing rod 36 is directly opposite to the outlet of the telescopic tube 241. A filter net 31 connects the follower plate 3 and the carrier plate 33. A valve is installed in the telescopic tube 241. The valve is electrically connected to the control system. One-way valves and flow meters are installed in the pipelines connecting the gas adding chamber, the water adding chamber and the air slide ring 217. The one-way valves and the flow meters are both electrically connected to the control system.

[0026] The follower plate 3 is located outside the crushing rod 36. A lifting plate 34 is rotatably installed on the outside of the follower plate 3 through a bearing. A telescopic shaft is connected between the lifting plate 34 and the bottom of the housing 11. The telescopic shaft is a telescopic structure. A telescopic spring 35 is sleeved on the telescopic shaft. The telescopic spring 35 connects the lifting plate 34 and the bottom of the housing 11. Both ends of the telescopic spring 35 are electrically connected to the control system.

[0027] Working principle: Press the start button on the control panel 1 to start the device. The staff removes the cover plate 114, places a certain number of clams on the screen 24, then closes the cover plate 114. The control system drives the stirring shaft 21 to rotate through the driving motor 2, and the stirring shaft 21 drives the brush 211 and the cam 25 to rotate accordingly; When the cam 25 rotates following the stirring shaft 21, the encoder in the driving motor 2 feeds back the rotation data of the cam 25 to the control system. Meanwhile, the protrusion on the cam 25 pushes the first vibrating plate 22 and the second vibrating plate 23 to move away from each other through the reciprocating rod 221. The reciprocating rods 221 on the first vibrating plate 22 and the second vibrating plate 23 both compress the first spring, that is, the first vibrating plate 22 and the second vibrating plate 23 both move to the side away from the cam 25. The first vibrating plate 22 pushes the air in the air adding chamber to be transported into the inlet of the air slip ring 217 through the pipeline, and the second vibrating plate 23 pushes the liquid in the water adding chamber to be transported into the inlet of the air slip ring 217 through the pipeline. Both the air and the liquid are transported into the interior of the stirring shaft 21 through the inlet and outlet of the air slip ring 217 and the pipeline; When the cam 25 continues to rotate and the protrusion on the cam 25 moves away from the first vibrating plate 22 and the second vibrating plate 23, the first springs on the first vibrating plate 22 and the second vibrating plate 23 are released. The first springs on both sides push the first vibrating plate 22 and the second vibrating plate 23 to move relatively, that is, the first vibrating plate 22 and the second vibrating plate 23 move to the side close to the cam 25. At this time, the first vibrating plate 22 extracts the external air and transports it into the air adding chamber through the pipeline, and the second vibrating plate 23 extracts the liquid from the external water source and transports it into the water adding chamber through the pipeline.

[0028] As the cam 25 continues to rotate, the first vibrating plate 22 and the second vibrating plate 23 continue to move away from each other and then move relatively. More and more air and liquid are transported into the interior of the stirring shaft 21, making the air and liquid mix while the pressure gradually increases. The air and liquid in the stirring shaft 21 are sprayed on the clams from the spraying ports on the brush 211, and the brush 211 scrubs the surface of the clams; When the first vibrating plate 22 and the second vibrating plate 23 move away from each other, the first vibrating plate 22 and the second vibrating plate 23 simultaneously stretch the screen 24, gradually flattening the folds on the screen 24. The screen 24 drives the clams to move upward, turning the clams over, so as to facilitate the cleaning of different positions of the clams. Through the scrubbing of the brush 211 and the flushing of the air and liquid, the cleaning effect of the clams is improved. The impurities generated after the clams are cleaned pass through the screen 24 and are discharged from the device through the discharge port 112.

[0029] After the clam is cleaned for the set time, the control system energizes the first electromagnet 215 and the second electromagnet 216, so that a magnetic field is generated after the first electromagnet 215 and the second electromagnet 216 are energized. The drive motor 2 synchronously drives the flexible film 213 and the metal plate to rotate through the stirring shaft 21. The metal plate cuts the magnetic induction lines in the magnetic field where the first electromagnet 215 and the second electromagnet 216 are energized, and an electric current is generated and heat is generated in the metal plate. The metal plate conducts the heat to the heat-conducting medium 214. After the heat-conducting medium 214 absorbs the heat, it expands. The heat-conducting medium 214 pushes the push plate 212 to move towards the middle of the stirring shaft 21. The push plate 212 pulls the flexible film 213 from the wrinkled state to the flattened state. At this time, the heat-conducting medium 214 conducts the heat to the air and liquid in the stirring shaft 21 through the flexible film 213, so that the high-temperature air and liquid are sprayed on the surface of the clam, and the cleaned clam is subjected to high-temperature steam to help the clam shelling process; When the clam is subjected to high-temperature steam for the set time, the control system opens the valve in the telescopic pipe 241 and controls the rotation motor 32 to work. The rotation motor 32 drives the carrier plate 33 and the crushing rod 36 to rotate. The cleaned clam is conveyed downward through the telescopic pipe 241, and the crushing rod 36 crushes the clam conveyed downward, causing the shell of the clam to break, so as to facilitate the shelling process. The broken clam falls on the carrier plate 33. The carrier plate 33 drives the filter screen 31 and the follower plate 3 to rotate at the same time. Due to the large centrifugal force generated by the high-speed rotation of the carrier plate 33, the meat in the clam will pass through the filter screen 31 and be discharged from the device through the discharge port 113, while the shell of the clam cannot pass through the filter screen 31; When the rotation motor 32 works for the set time, the clam shelling process is completed. At this time, the shells of the clam are deposited in the filter screen 31. At this time, the filter screen 31 needs to be cleaned for the next use. The control system energizes both ends of the telescopic spring 35. After the telescopic spring 35 is energized, a magnetic field that attracts each other is generated for each turn. This magnetic field causes the overall length of the telescopic spring 35 to shorten. The telescopic spring 35 pulls the lifting plate 34 to move downward. As the lifting plate 34 moves downward, the filter screen 31 gradually falls downward, turning the filter screen 31 over; Then, the staff removes the cover plate 114 and pours in an appropriate amount of water. The water passes through the sieve 24 and enters from the telescopic pipe 241. The water flushes the filter screen 31 downward from the telescopic pipe 241, washing down the shells and impurities of the clam in the filter screen 31. The impurities and the shells of the clam are both discharged from the device through the discharge port 113, realizing the cleaning process of the filter screen 31.
