[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0040] Please refer to Figures 1-6 , the present utility model provides a technical solution: a harvesting and capturing tool for mixed culture of mussels and blue clams, including a capture frame 1, a first limit rod 2, a metal fishing net 3, a drainage net 4, a first slide rail 5, a displacement rod 6, an interception rod 7, a second limit rod 8, a positioning frame 9, a second slide rail 10, a limit groove 11, a pushing frame 12, a connecting plate 13, a double-layer rotating rod sleeve 14, and a handheld screw rod 15;
[0041] Among them, the capture frame 1 is set as a rectangular frame structure. On both sides of the bottom end of the capture frame 1, the first limit rods 2 are arranged at equal intervals, and the bottom ends of the first limit rods 2 are connected to the positioning frame 9 and the metal fishing net 3. The metal fishing net 3 and the first limit rods 2 cooperate with the capture frame 1 to form a harvesting net for capturing shellfish, which is used to harvest mussels and blue clams in the aquaculture area;

[0044] Combined with the attached drawings of the specification Figures 1-6 As shown, when in use, the metal fishing net 3 is a mesh structure made of metal. The slide rail 1 on one side of the metal fishing net 3 is drilled and polished by a drilling device. The limit groove 11 inside the capture frame 1 and the slide rail 2 inside the positioning frame 9 are both processed and prepared by a drilling device. Then, the metal fishing net 3 is installed with the positioning frame 9. When in use, the water drainage net 4 passes through the internal holes to form a U-shaped structure, as Figures 1-2 shown, and remains stable between the capture frame 1 and the positioning frame 9. As the handheld screw rod 15 is installed on one side of the capture frame 1, as Figures 1-2 shown, it is convenient to take the whole, and it is convenient to salvage mussels and blue clams in the breeding pond. The internal holes of the water drainage net 4 are convenient for filtering out the liquid during the capture process. The double-layer rotating rod sleeve 14 threadedly connected to the surface of the handheld screw rod 15, as Figures 1-4 shown, wherein the double-layer rotating rod sleeve 14 is a double-layer pipe sleeve structure, and a stable bearing structure is formed by the rotation of the balls between the double-layer pipe sleeves, as Figure 1 shown;
[0045] The mixed capture assembly includes:
[0046] The slide rail 1, which is installed in a rectangular array in the metal net rod of the metal fishing net 3 perpendicular to the water drainage net 4;
[0047] The displacement rod 6, which is slidably connected to the slide rail 1 inside the metal fishing net 3, and the displacement rod 6 abuts against one side of the metal fishing net 3;
[0048] The intercepting rod 7, which is connected to both ends of the displacement rod 6, and the intercepting rod 7 is made of metal. The intercepting rod 7 and the displacement rod 6 form a U-shaped metal structure;
[0049] The second limiting rod 8, which is arranged parallel to the intercepting rod 7, and the second limiting rod 8 is equidistantly arranged on both sides of the positioning frame 9. The top end of the second limiting rod 8 is vertically installed with the bottom end of the capture frame 1, and the second limiting rod 8 and the first limiting rod 2 are installed between the capture frame 1 and the positioning frame 9;
[0050] The slide rail 2, which is arranged on both sides of the positioning frame 9, and the inside of the slide rail 2 is slidably connected to the intercepting rod 7 and the displacement rod 6. The slide rail 2 is set as an L-shaped chute structure, and the openings on both sides of the slide rail 2 are respectively aligned with the slide rail 1 and the limit groove 11;
[0051] The limiting grooves 11 are equidistantly arranged on both sides inside the capture frame 1, and the top ends of the intercepting rods 7 are slidably connected inside the limiting grooves 11;
[0052] The pushing frame 12 has its two ends respectively connected to the intercepting rods 7 passing through the limiting grooves 11, and the pushing frame 12 is arranged as a U-shaped rod structure;
[0053] The connecting plate 13 is arranged on one side of the pushing frame 12, and the connecting plate 13 is located above the hand-held screw rod 15. The bottom end of the connecting plate 13 is connected to the outer sleeve of the double-layer rotating rod sleeve 14;
[0054] Combined with the attached drawings of the specification Figures 1-6 As shown, when in use, the displacement rod 6 is passed through the first slide rail 5 inside the metal fishing net 3, and the intercepting rods 7 at both ends of the displacement rod 6 are passed through the second slide rail 10 inside the positioning frame 9. As Figures 1-3 shown, when in use, by rotating the inner sleeve structure of the double-layer rotating rod sleeve 14, the outer sleeve of the double-layer rotating rod sleeve 14 pushes the connecting plate 13 to drive the pushing frame 12 to displace, so that the pushing frame 12 pushes the intercepting rod 7 to slide inside the limiting groove 11, so that the displacement rod 6 and the intercepting rod 7 further separate the distance between the metal fishing net 3 and the second limiting rod 8. When in use, a small-mesh net is used to catch mussels and blue clams. As Figure 2 shown, after the fishing is completed, rotate the double-layer rotating rod sleeve 14 to retract the positions of the displacement rod 6 and the intercepting rod 7, and further enlarge the internal mesh. Since the volumes of mussels and blue clams are quite different, by shaking the whole on the harvesting concentration frame, the blue clams fall into the harvesting concentration frame through the large gaps between the second limiting rods 8, realizing the classification harvesting operation and reducing the later operation.
[0055] Working principle: When using this harvesting and capturing tool for mussel and blue clam polyculture, by rotating the inner tube of the double-layer rotating rod sleeve 14 and pushing it along the thread direction of the hand-held screw rod 15, the connecting plate 13 and the pushing frame 12 on the outer appearance of the double-layer rotating rod sleeve 14 are driven, so that the pushing frame 12 drives several installed intercepting rods 7 to displace and slide along the limiting grooves 11, so that the displacement rod 6 and the intercepting rod 7 further fill the gap between the metal fishing net 3 and the second limiting rod 8. By directly digging and fishing the mussels and blue clams that need to be harvested in the aquaculture area with the hand-held screw rod 15, after the fishing is completed, rotate the inner tube of the double-layer rotating rod sleeve 14 in the reverse direction, so that the pushing frame 12 drives the intercepting rod 7 and the displacement rod 6 to reset, so that the internal mesh area of the metal fishing net 3 increases. Above the blue clam harvesting concentration frame, by shaking the whole, the smaller blue clams fall through the enlarged mesh, and then the mussels inside the metal fishing net 3 are sent into the harvesting concentration frame, realizing the rapid harvesting and capturing of the polycultured mussels and blue clams, and increasing the overall practicability.
