Description

Technical Field

[0001] The present invention relates to the technical field of mussel shelling, in particular to a mussel meat detection shelling device and an operation method thereof. Background Art

[0002] Mussels are a general term for a class of animals in the family Unionidae of the phylum Mollusca, and are called mussel shells and warped ones in some places. They live at the bottom of freshwater lakes, ponds, rivers, etc. In the natural environment, mussels generally live in mud, sand or gravel in rivers, lakes, ponds, small streams, etc. In winter and spring when it is cold, they use their hatchet feet to dig mud, so that part of the mussel body is buried in the sediment, with the anterior ventral margin downward and the posterior dorsal margin upward; only the posterior edge of the shell is exposed for breathing and feeding. When it is hot, most of them are exposed outside the mud. Mussel meat can be eaten, and can also be used as bait for fish and poultry, and feed for poultry and livestock. Mussel meat is quite popular among many seafood lovers in daily life. Mussel meat is rich in high protein and contains nutrients that can improve the body's immunity to a certain extent. It is an important high-protein component of the human body. Since mussel meat is rich in calcium, it can also stimulate the growth of bone matrix and bone cells to a certain extent, and help the precipitation of calcium salts in bone tissue, playing a role in strengthening bones. Mussel meat itself has the functions of nourishing yin and clearing heat, and is suitable for dry mouth, red eyes caused by yin deficiency and internal heat, and hyperthyroidism. In daily life, mussels can also effectively and quickly relieve headache, blushing after drinking, and can relieve alcohol and accelerate the excretion of alcohol. At the same time, it can relieve the damage of alcohol to the gastric mucosa and has a certain protective effect on the liver. During the mussel breeding process, it is usually necessary to regularly detect the quality of mussel meat, and before detection, it is necessary to shell the mussels first.

[0003] After retrieval, a continuous mussel opening device disclosed in a Chinese patent with the publication number CN112931596A includes a conveyor belt mechanism. Legs are arranged on the outer wall of the conveyor belt mechanism, a support frame is arranged at the top of the conveyor belt mechanism, an opening mechanism is arranged at a position close to the right side of the outer wall of the support frame, the outer wall of the opening mechanism is movably connected to the outer wall of the conveyor belt mechanism through the arranged support frame, and a collection box is arranged at a position close to the right side of the bottom end of the conveyor belt mechanism.

[0004] After retrieval, an automatic mussel shelling device disclosed in a Chinese patent with the publication number CN204579703U is composed of a mussel shelling frame, a mussel feeding frame, a mussel feeding conveyor mechanism, a mussel shelling mechanism and a mussel recovery frame. The mussel shelling frame is connected to the mussel feeding frame, the mussel feeding conveyor mechanism is fixed on the mussel feeding frame, the mussel shelling mechanism is fixed on the mussel shelling frame, the mussel recovery frame is fixed on the mussel shelling frame, the mussel feeding conveyor mechanism is responsible for vertically feeding mussels into the mussel shelling mechanism, and the mussel shelling frame can open a small hole in the upper part of the mussel and open the mussel.

[0005] From the above prior art, it can be understood that traditional mussel shell-opening devices are usually large mechanical equipment. Although they can achieve the shell-opening operation of mussels, they are not suitable for use in the meat quality detection of mussel farming. Of course, the current traditional shell-opening method is mainly that the staff holds a knife in one hand and a mussel in the other hand, and then gradually inserts the knife into the closed opening of the mussel and cuts it open. This process is very likely to cause the knife to scratch the hand. Summary of the Invention

[0006] The purpose of the present invention is to provide a shell-opening device for mussel meat detection and its operation method to solve the problems raised in the above background technology.

The end of the guide rod away from the convex plate is fixedly installed with a limit block. Rubber pads are bonded to the opposite surfaces of the assembly plate;

[0011] The trimming mechanism includes a mounting shell, which is fixedly installed on the outer side of the mounting frame. A storage box is inserted into the inner side of the mounting shell.

[0016] A method for opening the shell of mussel meat for detection includes the following manufacturing method steps:

[0017] S1. Before detecting the mussel meat, it is necessary to perform shell opening treatment. Before shell opening, the edge of the mussel is first pre-treated. During the pre-treatment process, the closed mouth of the mussel is pulled forward from the gap between the baffles and attached to the mounting shell, so that the cutting knife at the strip hole can trim the closed mouth of the mussel, and the trimmed scraps enter the storage box in the mounting shell through the strip hole for collection;

[0018] S2. Subsequently, turn on the infrared emitter at the upper bracket of the mounting frame, and then place the mussel on the mounting frame according to the position of the infrared line point, and the closed mouth of the mussel corresponds to the infrared line point;

[0019] S3. Then, operate the crank to rotate the bidirectional screw on the mounting frame, so that the two convex plates threadedly connected to the outside of the bidirectional screw slide closer to each other. Since the guide rod with a limit block on the convex plate is connected to the same assembly plate with a rubber pad and cooperates with the third spring, the assembly plate can elastically clamp both sides of the mussel;

[0020] S4. Finally, press down the operating handles at two places on the mounting frame, so that the operating handles drive the top frame to move through the operating rods. The top frame slides downward on the fixed frame through the round rod. At the same time, the top frame cooperates with the fixed frame to compress the second spring, and the lower end of the round rod drives the shell-opening tool connected by the fixing plate to move downward from top to bottom, and the closed opening of the mussel can be shelled;

[0021] S5. When the shell-opening tool needs to be replaced and disassembled after the mussel is shelled, only need to pull the pull handle, so that the pull handle drives the pull plate to slide in the installation cavity through the pull rod. When the clamping block at the lower end of the pull plate is separated from the clamping groove at the connecting block part of the shell-opening tool, the shell-opening tool can be pushed out from the connecting groove of the tool holder from back to front to be removed;

[0022] S6. When installing a new shell-opening tool, insert the connecting block at the upper end of the shell-opening tool along the connecting groove of the tool holder. During the insertion process, the insertion end of the connecting block squeezes the inclined surface of the clamping block protruding from the connecting groove, so that the pull plate connected to the clamping block slides in the installation cavity and compresses the first spring. Until the clamping end of the clamping block corresponds to the clamping groove of the connecting block, at this time, the first spring elastically resets and pushes the pull plate downward, and the clamping block at the lower end of the pull plate is clamped into the clamping groove to complete the installation of the shell-opening tool.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] First, in the present invention, by pressing down the operating handles with both hands, the operating handles pull the operating rods, so that the top frame connected to the operating rods moves downward. The top frame slides downward on the fixed frame through the round rod. At the same time, the top frame cooperates with the fixed frame to compress the second spring, and the lower end of the round rod drives the shell-opening tool connected by the fixing plate to move downward from top to bottom, and the closed opening of the mussel can be shelled. After the operation is completed, release the operating handle, and the top frame rises under the action of the second spring reset. At this time, it is convenient for the user to remove the shelled mussel from the mounting frame, so that the shelling operation of the mussel can be facilitated, and during the whole operation process, the user does not need to contact the shell-opening tool, and the safety is relatively good;

[0025] Second, in the present invention, the connecting block at the upper end of the shell-opening tool is inserted along the connecting groove of the tool holder. During the insertion process, the insertion end of the connecting block squeezes the inclined surface of the clamping block protruding from the connecting groove, causing the pull plate connected to the clamping block to slide in the installation cavity and compress the first spring. Until when the clamping end of the clamping block corresponds to the clamping groove of the connecting block, at this time, the first spring elastically resets and pushes the pull plate downward, and the clamping block at the lower end of the pull plate is clamped into the clamping groove to complete the installation of the shell-opening tool. By pulling the pull handle, the pull handle drives the pull plate to slide in the installation cavity through the pull rod. When the clamping block at the lower end of the pull plate separates from the clamping groove at the connecting block part of the shell-opening tool, the shell-opening tool can be pushed forward from the connecting groove of the tool holder from back to front to be removed, so that the disassembly, assembly and replacement of the shell-opening tool can be conveniently carried out;

[0026] Third, in the present invention, according to the positioning points of the infrared emitter, the closed mouth of the mussel is placed correspondingly on the mounting rack, and at the same time, the crank is operated to rotate the bidirectional screw on the mounting rack, so that the two convex plates threadedly connected to the outside of the bidirectional screw approach and slide towards each other. Since the guide rod with a limiting block on the convex plate and the assembly plate with the same rubber pad are connected and cooperate with the third spring, the assembly plate can elastically clamp both sides of the mussel, so that the positioning and fixing of the mussel can be conveniently carried out;

[0027] Fourth, in the present invention, the closed mouth of the mussel is pulled forward from back to front through the gap between the baffles and attached to the mounting shell, so that the cutting tool at the strip hole can trim the closed mouth of the mussel, and the trimmed scraps enter the storage box in the mounting shell through the strip hole for collection. The gap of the trimmed closed mouth of the mussel is also larger, which is more convenient for subsequent shell-opening operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The operating mechanism 11 includes a round rod 115 which is symmetrically and slidably connected to the inner side of the fixed frame 6. A same fixing plate 111 is fixedly installed at the lower end of the round rod 115, and a same top frame 112 is fixedly installed at the upper end of the round rod 115. A second spring 116 is fixedly installed between the top frame 112 and the fixed frame 6. One end of the round rod 115 movably penetrates through the middle of the second spring 116. A handle 117 is fixedly installed at the upper end of the top frame 112. Operating rods 113 are symmetrically and fixedly installed at the lower end of the top frame 112. The lower ends of the operating rods 113 slidably penetrate through the wall of the mounting frame 2 and are fixedly installed with operating handles 114. The knife holder 10 is fixedly installed at the lower end of the fixing plate 111. When the mussel is fixed by the clamping mechanism 3 on the mounting frame 2, hold the operating handles 114 with both hands and press down, so that the operating handles 114 pull the operating rods 113, causing the top frame 112 connected to the operating rods 113 to move downward. And the top frame 112 slides downward on the fixed frame 6 through the round rod 115. At the same time, the top frame 112 cooperates with the fixed frame 6 to compress the second spring 116, and the shell-opening cutter 8 connected to the fixing plate 111 through the round rod 115 moves downward from top to bottom, so that the shell-opening operation can be carried out on the closed opening of the mussel.

A pull rod 905 is fixedly installed at the upper end of the pull plate 902. A first spring 904 is sleeved on the end of the pull rod 905 close to the pull plate 902. The end of the pull rod 905 far from the pull plate 902 slidably penetrates through the cavity wall of the installation cavity 901 and is fixedly installed with a pull handle 906. When replacing and disassembling the split shell cutter 8, only need to pull the pull handle 906, so that the pull handle 906 drives the pull plate 902 to slide in the installation cavity 901 through the pull rod 905. When the clamping block 903 at the lower end of the pull plate 902 is separated from the clamping groove 802 at the connecting block 801 part of the split shell cutter 8, the split shell cutter 8 can be taken off by pushing it forward from the connecting groove 16 of the tool holder 10 from back to front. When installing the split shell cutter 8, insert the connecting block 801 at the upper end of the split shell cutter 8 along the connecting groove 16 of the tool holder 10. During the insertion process, the insertion end of the connecting block 801 squeezes the inclined surface of the clamping block 903 protruding from the connecting groove 16, so that the pull plate 902 connected to the clamping block 903 slides in the installation cavity 901 and compresses the first spring 904. Until when the clamping end of the clamping block 903 corresponds to the clamping groove 802 of the connecting block 801, at this time, the first spring 904 elastically resets and pushes the pull plate 902 downward, and makes the clamping block 903 at the lower end of the pull plate 902 snap into the clamping groove 802 to complete the installation of the split shell cutter 8, thus facilitating the disassembly, replacement and use of the split shell cutter 8;

[0047] A shell-opening operation method for mussel meat detection includes the following manufacturing method steps:

[0048] S1. Before detecting the mussel meat, it needs to be shelled. Before shelling, the edge of the mussel is first pretreated. During the pretreatment process, the closed mouth of the mussel is pulled forward from the gap between the baffles 502 and attached to the installation shell 501, so that the cutting knife 503 at the strip hole 504 can trim the closed mouth of the mussel, and the trimmed scraps enter the storage box 505 in the installation shell 501 through the strip hole 504 for collection;

[0049] S2. Subsequently, turn on the infrared emitter 401 at the upper bracket 4 of the mounting bracket 2, and then place the mussel on the mounting bracket 2 according to the position of the infrared line points, with the closed mouth of the mussel corresponding to the infrared line points;

[0050] S3. Then, operate the crank 301 to rotate the bidirectional screw 309 on the mounting bracket 2, so that the two convex plates 302 threadedly connected to the outside of the bidirectional screw 309 slide closer to each other. Since the guide rod 305 with the limit block 307 on the convex plate 302 is connected to the assembly plate 303 with the same rubber pad 304 and cooperates with the third spring 306, the assembly plate 303 can elastically clamp both sides of the mussel;

[0051] S4. Finally, press down the operating handles 114 at two places on the mounting bracket 2, so that the operating handles 114 drive the top frame 112 to move through the operating rod 113. The top frame 112 slides downward on the fixed frame 6 through the round rod 115. At the same time, the top frame 112 cooperates with the fixed frame 6 to compress the second spring 116. The lower end of the round rod 115 drives the shell-opening cutter 8 connected by the fixing plate 111 to move downward from top to bottom, and the closed mouth of the mussel can be opened;

[0052] S5. When it is necessary to replace and disassemble the shell-opening cutter 8 after the mussel is opened, only need to pull the pull handle 906, so that the pull handle 906 drives the pull plate 902 to slide in the installation cavity 901 through the pull rod 905.
