Description

Technical Field

[0001] This invention relates to the field of aquatic product processing technology, specifically a mechanical device for shelling clams. Background Technology

[0002] In the seafood processing industry, clams are a popular shellfish ingredient, prized for their delicious meat and rich nutritional value. However, the pre-processing of clams, especially the shelling process, has always been a key factor limiting processing efficiency and product quality. Traditional clam shelling methods rely primarily on manual labor, which is not only labor-intensive but also inefficient, failing to meet the growing market demand. Furthermore, manual shelling can easily damage the clam meat, affecting the final product's appearance and taste. Summary of the Invention

[0003] The purpose of this invention is to provide a mechanical device for shelling clams, in order to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a mechanical device for shelling clams, comprising a shell, a drive motor mounted on the shell, a stirring shaft connected to the output end of the drive motor, a first vibrating plate and a second vibrating plate respectively mounted on both sides of the stirring shaft, a screen connected between the first vibrating plate and the second vibrating plate, a partition plate mounted below the screen, discharge ports provided on both sides of the partition plate, a following plate mounted below the partition plate, a filter screen mounted below the following plate, a rotary motor mounted below the filter screen, and a discharge port provided on the outer side of the filter screen.

[0005] The stirring shaft is hollow inside, and several brushes are arranged on the outside of the stirring shaft. The brushes are all connected to the inside of the stirring shaft, and spray nozzles are opened on the brushes away from the stirring shaft.

[0006] A pusher plate is slidably installed inside the stirring shaft. A flexible membrane and a reset spring are connected between the pusher plate and the stirring shaft. The reset spring is located inside the flexible membrane. Several folds are provided on the flexible membrane. A heat-conducting medium is provided inside the flexible membrane. The heat-conducting medium is a material that expands when heated. Several metal plates are provided on the flexible membrane. All metal plates are in contact with the heat-conducting medium. A first electromagnet and a second electromagnet are provided on both the first and second vibrating plates. The metal plates are located within the magnetic fields of the first and second electromagnets.

[0007] The greater the magnetic field strength generated by the first and second electromagnets working together, the greater the current generated by the metal plate cutting the magnetic field lines, the greater the heat generated by the metal plate, the greater the degree of expansion of the heat-conducting medium, and the larger the contact area between the flexible membrane and the air and liquid. This allows for the simultaneous heating of more air and liquid. Therefore, the control system can adjust the heating efficiency of air and liquid by adjusting the magnetic field strength of the first and second electromagnets to meet different application requirements.

[0008] The upper side of the shell is provided with an air filling chamber and a water filling chamber, respectively. The first vibrating plate and the second vibrating plate slide in the air filling chamber and the water filling chamber, respectively. The air filling chamber is connected to the outside air through a pipe, and the water filling chamber is connected to the outside water source through a pipe.

[0009] An air slip ring is installed on one side of the stirring shaft. The air slip ring is mounted on the housing. The inlet of the air slip ring is connected to the air filling chamber and the water filling chamber through pipes. The outlet of the air slip ring is connected to the middle of the stirring shaft through a pipe.

[0010] Both ends of the first and second vibrating plates are provided with reciprocating rods. A fixed plate is provided on the housing directly opposite the reciprocating rod. A cam is provided on the stirring shaft. The cam is located between several brushes and air slip rings. Several protrusions are provided on the outer side of the cam. The reciprocating rod passes through the fixed plate and abuts against the protrusions on the cam. The reciprocating rod slides within the fixed plate. A first spring connects the fixed plate and the reciprocating rod.

[0011] The screen is provided with several pleats, and a telescopic tube is connected between the screen and the partition. The telescopic tube is a flexible tube, and the partition is installed on the housing.

[0012] The rotary motor is mounted on the housing, and a carrying plate and a crushing rod are mounted on the output shaft of the rotary motor. The crushing rod is located above the carrying plate and faces the outlet of the telescopic tube. The filter screen is connected to the following plate and the carrying plate.

[0013] The following plate is located outside the crushing rod. A lifting plate is rotatably mounted on the outside of the following plate via a bearing. A telescopic shaft is connected between the lifting plate and the bottom of the housing. The telescopic shaft is a telescopic structure. A telescopic spring is sleeved on the telescopic shaft. The telescopic spring connects the lifting plate and the bottom of the housing. Both ends of the telescopic spring are electrically connected to the control system.

[0014] A valve is installed inside the telescopic pipe, and the valve is electrically connected to the control system. One-way valves and flow meters are installed in the pipes connected to the air filling chamber, water filling chamber, and air slip ring, and the one-way valves and flow meters are electrically connected to the control system.

[0015] A cover plate is provided on the housing above the stirring shaft, and the cover plate and the housing are connected by a snap-fit ​​connection.

[0016] Displacement sensors are installed on both the first and second vibration plates, and the displacement sensors are electrically connected to the control system.

[0017] Both the feed port and the discharge port are located on the housing. The drive motor and the rotary motor have built-in encoders and pressure sensors, which are electrically connected to the control system.

[0018] The housing is equipped with a control panel, and the control panel contains a control system.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Automated clam shelling process with high efficiency. A rotary motor drives a carrying plate and a crushing rod to rotate. After washing, the clams are conveyed downwards through a telescopic tube. The crushing rod crushes the clams as they are conveyed downwards, breaking the shells to facilitate shelling. The broken clams fall onto the carrying plate, which simultaneously drives a filter screen and a follower plate to rotate. Due to the high-speed rotation of the carrying plate, a large centrifugal force is generated, causing the clam meat to pass through the filter screen and be discharged from the discharge port. Workers collect and process the discharged meat, achieving automated shelling with high efficiency.

[0021] 2. Clam cleaning process to prevent impurities from contaminating the shell and meat. The first and second vibrating plates continuously move back-to-back and then relative to each other. More and more air and liquid are delivered into the interior of the stirring shaft, causing the air and liquid to mix while the pressure gradually increases. The air and liquid inside the stirring shaft are sprayed onto the clams through the nozzles on the brushes, while the brushes scrub the surface of the clams. When the first and second vibrating plates move back-to-back, they simultaneously stretch the screen, gradually flattening the wrinkles on the screen. The screen drives the clams upward, turning them over so that different parts of the clams can be cleaned. Through brushing and rinsing with air and liquid, the cleaning effect of the clams is improved, preventing impurities from contaminating the shell and meat.

[0022] 3. High-temperature steam-assisted shell removal process improves shell removal efficiency. A metal plate cuts magnetic field lines within the magnetic field of the first and second electromagnets, generating current and heat within the plate. This heat is transferred to a heat-conducting medium, which absorbs the heat and expands. The medium then pushes a pusher plate towards the center of the stirring shaft. This pusher plate pulls a flexible membrane from a wrinkled state to a flattened state. At this point, the heat-conducting medium transfers heat through the flexible membrane to the air and liquid within the stirring shaft, allowing the high-temperature air and liquid to be sprayed onto the surface of the clams. This high-temperature steam treatment aids in shell removal, improving efficiency. Attached Figure Description

[0036] Example: Figures 1-11 As shown, the present invention provides a technical solution for a mechanical device for shelling clams, comprising a housing 11, a drive motor 2 mounted on the housing 11, a stirring shaft 21 connected to the output end of the drive motor 2, a cover plate 114 disposed on the housing 11 above the stirring shaft 21, the cover plate 114 and the housing 11 being connected by a snap-fit ​​connection, a first vibrating plate 22 and a second vibrating plate 23 respectively mounted on both sides of the stirring shaft 21, a screen 24 connected between the first vibrating plate 22 and the second vibrating plate 23, and a partition plate 111 installed below the screen 24. The partition 111 has discharge ports 112 on both sides, a following plate 3 is installed below the partition 111, a filter screen 31 is installed below the following plate 3, a rotary motor 32 is installed below the filter screen 31, and a discharge port 113 is provided on the outside of the filter screen 31. Both the discharge port 112 and the discharge port 113 are located on the housing 11. The drive motor 2 and the rotary motor 32 have built-in encoders and pressure sensors. The encoders and pressure sensors are electrically connected to the control system. The housing 11 has a control panel 1, and the control system is located inside the control panel 1.

[0037] Displacement sensors are installed on both the first vibrating plate 22 and the second vibrating plate 23. These sensors are electrically connected to the control system. Reciprocating rods 221 are installed at both ends of the first and second vibrating plates 22 and 23. A fixed plate is installed on the housing 11 directly opposite the reciprocating rods 221. A cam 25 is installed on the stirring shaft 21, located between several brushes 211 and air slip rings 217. Several protrusions are provided on the outer side of the cam 25. The reciprocating rods 221 pass through the fixed plate and abut against the protrusions on the cam 25. The reciprocating rods 221 slide within the fixed plate. The fixed plate and... A first spring is connected between the reciprocating rods 221; an air filling chamber and a water filling chamber are respectively provided on the upper side of the housing 11, and the first vibrating plate 22 and the second vibrating plate 23 slide in the air filling chamber and the water filling chamber respectively. The air filling chamber is connected to the outside air through a pipe, and the water filling chamber is connected to the outside water source through a pipe; an air slip ring 217 is installed on one side of the stirring shaft 21. The air slip ring 217 is installed on the housing 11. The inlet of the air slip ring 217 is connected to the air filling chamber and the water filling chamber through pipes respectively, and the outlet of the air slip ring 217 is connected to the middle of the stirring shaft 21 through a pipe.

[0038] The stirring shaft 21 is hollow inside, and several brushes 211 are arranged on the outside of the stirring shaft 21. The brushes 211 are all connected to the inside of the stirring shaft 21. A spray nozzle is opened on the brush 211 at the end away from the stirring shaft 21. A push plate 212 is slidably installed inside the stirring shaft 21. A flexible membrane 213 and a reset spring are connected between the push plate 212 and the stirring shaft 21. The reset spring is located inside the flexible membrane 213. Several pleats are arranged on the flexible membrane 213. A heat-conducting medium 214 is arranged inside the flexible membrane 213. The heat-conducting medium 214 is a material that expands when heated. Several metal plates are arranged on the flexible membrane 213. The metal plates are all in contact with the heat-conducting medium 214. A first electromagnet 215 and a second electromagnet 216 are arranged on the first vibrating plate 22 and the second vibrating plate 23. The metal plates are located in the magnetic field of the first electromagnet 215 and the second electromagnet 216.

[0039] The greater the magnetic field strength generated by the first electromagnet 215 and the second electromagnet 216, the greater the current generated by the metal plate cutting the magnetic field lines, the greater the heat generated by the metal plate, the greater the expansion of the heat-conducting medium 214, and the larger the contact area between the flexible membrane 213 and the air and liquid. This allows for the simultaneous heating of more air and liquid. Therefore, the control system can adjust the heating efficiency of air and liquid by adjusting the magnetic field strength of the first electromagnet 215 and the second electromagnet 216 to meet different application requirements.

[0040] The screen 24 has several pleats. A telescopic tube 241, which is a flexible tube, connects the screen 24 and the partition 111. The partition 111 is installed on the housing 11. The rotary motor 32 is installed on the housing 11. A carrying plate 33 and a crushing rod 36 are installed on the output shaft of the rotary motor 32. The crushing rod 36 is located above the carrying plate 33 and faces the outlet of the telescopic tube 241. The filter screen 31 connects the following plate 3 and the carrying 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 pipes connecting the air filling chamber, the water filling chamber, and the air slip ring 217. Both the one-way valves and the flow meters are electrically connected to the control system.

[0041] The following plate 3 is located outside the crushing rod 36. A lifting plate 34 is rotatably mounted on the outside of the following plate 3 via 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.

[0042] Working principle: Press the start button on the control panel 1 to start the device. The operator removes the cover plate 114 and puts a certain number of clams on the screen 24. Then close the cover plate 114. The control system drives the stirring shaft 21 to rotate through the drive motor 2. The stirring shaft 21 drives the brush 211 and cam 25 to rotate accordingly.

[0043] When the cam 25 rotates with the stirring shaft 21, the encoder in the drive motor 2 feeds back the rotation data of the cam 25 to the control system. The protrusion on the cam 25 simultaneously 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 rod 221 on the first vibrating plate 22 and the second vibrating plate 23 compress the first spring, that is, the first vibrating plate 22 and the second vibrating plate 23 move away from the cam 25. The first vibrating plate 22 pushes the air in the air filling chamber to be transported to the inlet of the air slip ring 217 through the pipe. The second vibrating plate 23 pushes the liquid in the water filling chamber to be transported to the inlet of the air slip ring 217 through the pipe. Both air and liquid are transported to the interior of the stirring shaft 21 through the inlet and outlet of the air slip ring 217 and the pipe.

[0044] As the cam 25 continues to rotate, when 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 relative to each other, that is, the first vibrating plate 22 and the second vibrating plate 23 move towards the side closer to the cam 25. At this time, the first vibrating plate 22 draws in external air and delivers it to the air filling chamber through the pipe, and the second vibrating plate 23 draws in liquid from the external water source and delivers it to the water filling chamber through the pipe.

[0045] As the cam 25 continues to rotate, the first vibrating plate 22 and the second vibrating plate 23 continue to move back to back and then relative to each other. More and more air and liquid are delivered into the interior of the stirring shaft 21, so that the air and liquid are mixed and the pressure gradually increases. The air and liquid in the stirring shaft 21 are sprayed onto the clam from the spray nozzle on the brush 211, and the brush 211 brushes the surface of the clam.

[0046] When the first vibrating plate 22 and the second vibrating plate 23 move in opposite directions, the first vibrating plate 22 and the second vibrating plate 23 simultaneously stretch the screen 24, causing the wrinkles on the screen 24 to gradually flatten. The screen 24 drives the clams to move upward, turning the clams over so that different parts of the clams can be cleaned. The cleaning effect of the clams is improved by brushing with the brush 211 and rinsing with air and liquid. The impurities generated after the clams are cleaned pass through the screen 24 and are discharged from the device through the discharge port 112.

[0047] After the clams have been cleaned for the set time, the control system energizes the first electromagnet 215 and the second electromagnet 216, which generate a magnetic field. The drive motor 2 synchronously drives the flexible membrane 213 and the metal plate to rotate via the stirring shaft 21. The metal plate cuts magnetic lines of force within the magnetic field generated by the energized electromagnets 215 and 216, generating current and heat within the metal plate. The metal plate conducts the heat to the heat-conducting medium 214, which expands after absorbing the heat. The heat-conducting medium 214 pushes the push plate 212 toward the center of the stirring shaft 21. The push plate 212 pulls the flexible membrane 213 from a wrinkled state to a flat state. At this time, the heat-conducting medium 214 conducts heat through the flexible membrane 213 to the air and liquid in the stirring shaft 21, so that the high-temperature air and liquid are sprayed onto the surface of the clams, subjecting the cleaned clams to high-temperature steaming to help with the shell removal process.

[0048] When the clams are steamed at high temperature for a set time, the control system opens the valve in the telescopic tube 241 and controls the rotary motor 32 to work. The rotary motor 32 drives the carrying plate 33 and the crushing rod 36 to rotate. After cleaning, the clams are conveyed downward through the telescopic tube 241. The crushing rod 36 crushes the clams conveyed downward, causing the clam shells to break, so that they can be shelled. The broken clams fall onto the carrying plate 33. The carrying plate 33 simultaneously drives the filter screen 31 and the following plate 3 to rotate. Due to the high-speed rotation of the carrying plate 33, a large centrifugal force is generated. The meat inside the clam will pass through the filter screen 31 and be discharged from the device through the discharge port 113, while the clam shells cannot pass through the filter screen 31.

[0049] After the rotary motor 32 has been running for a set time, the clams have finished shelling. At this time, the clam shells are deposited in the filter screen 31. 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, each turn of the telescopic spring 35 generates a magnetic field that attracts each other. This magnetic field causes the telescopic spring 35 to shorten as a whole. The telescopic spring 35 pulls the lifting plate 34 downward. As the lifting plate 34 moves downward, the filter screen 31 gradually falls down, causing the filter screen 31 to flip over. Afterward, the operator removes the cover plate 114, pours in an appropriate amount of water, and the water enters through the telescopic pipe 241 after passing through the screen 24. The water flows down from the telescopic pipe 241 to rinse the filter screen 31, washing away the clam shells and impurities inside the filter screen 31. The impurities and clam shells are discharged from the device through the discharge port 113, thus achieving the cleaning treatment of the filter screen 31.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
