Description

Technical Field

[0001] The utility model relates to the technical field of fishing cages, in particular to a sea crab fishing cage. Background Art

[0002] A saltwater crab trap is a device used to catch crabs or crab-like animals in seawater, usually used in fisheries and fishing activities. Usually some baits that attract crabs, such as fish meat, fish heads or other foods, are placed in the trap to attract crabs to enter the trap for capture.

[0003] Announcement No. CN207803232U discloses a crab catching device with automatic sorting function, including a crab cage and a bait cage arranged in the crab cage, the crab cage includes an external frame and an outer net covered on the external frame, a plurality of external trapping ports are arranged on the outer net, the external trapping ports are connected with the interior of the crab cage, and are used to lure large crabs and small crabs into the crab cage, the bait cage includes an internal frame and an inner net covered on the internal frame, a plurality of internal trapping ports are arranged on the inner net, the internal trapping ports are connected with the interior of the bait cage, and are used to lure small crabs into the bait cage, and the aperture of the external trapping ports is larger than the aperture of the internal trapping ports. Although the utility model can realize the capture of crabs of different sizes in different cages and achieve the purpose of individual preliminary classification of crabs, traditional sea crab fishing cages are generally in the form of meshes. When taking crabs, the crabs may be hung on the net, resulting in broken crab legs and affecting sales. When using the sea crab fishing cage, the bait is generally poured directly into the sea crab fishing cage. This may cause the bait to float into the sea through the gaps in the net, thereby affecting the crab catching efficiency of the sea crab fishing cage, so improvement is needed.

The design of the connecting rope B12, the bait storage box 13 and the odor dispersion holes 14 is to allow the bait to be stored in the middle position of the metal cage 2, avoiding the phenomenon of the bait moving out of the gap of the metal cage 2, so that the crab luring effect of the seawater crab fishing cage is better. Through the arrangement of the metal cage 2, the upper cover plate 1, the sealing mesh plate 8 and the lower cover plate 3, when taking crabs from the seawater crab fishing cage, the phenomenon of the crab legs being hung up by the net is prevented, making the seawater crab fishing cage more practical.

[0025] Embodiment 2

[0026] See also Figure 1-2 A fixing mechanism is provided at the top of the upper cover plate 1, and the fixing mechanism includes a fixing block 9, which is fixedly installed on the top of the upper cover plate 1, and a connecting rope A10 is fixedly installed on the top of the fixing block 9, and a fixing ring 11 is fixedly installed on the top of the connecting rope A10. The fixing blocks 9 are arranged in a circle at the top edge of the upper cover plate 1. The design of the connecting rope A10, the fixing block 9 and the fixing ring 11 is to enable the rope connected to the seawater crab fishing cage to be tied to the center of the seawater crab fishing cage, so that the seawater crab fishing cage can be taken more smoothly and labor-saving, and the fixing ring 11 makes the installation and fixation of the seawater crab fishing cage more convenient and quick.

[0027] Working principle: When using the sea crab fishing cage, first hold the straight rod 6 and rotate it around the mounting ring 7, thereby driving the mounting ring 7 to rotate, so that the mounting ring 7 rotates on the external thread ring block 15, until it rotates away from the external thread ring block 15, and then the sealing mesh plate 8 can be driven to be removed, then the bait storage box 13 is taken out from the inside of the metal cage 2, and the bait is placed in the bait storage box 13, and the bait storage box 13 is placed in the metal cage 2, and under the tension of multiple connecting ropes B12, the bait storage box 13 is suspended in the metal cage 2, then the sealing mesh plate 8 is picked up and placed on the external thread ring The top of the shaped block 15 is screwed, and the mounting ring 7 is screwed into the external threaded ring block, so that the sealing mesh plate 8 is limited and fixed. At this time, the rope is picked up and fixed on the fixing ring 11, and the other end of the rope is fixed on the shore. The seawater crab catching cage can be thrown into the sea, and the odor dissipation hole 14 will emit the smell of the bait, thereby inducing the crab to enter the metal cage 2 from the crab inlet 4. Under the setting of the anti-runaway crab cage 5, the phenomenon of crabs running out of the crab inlet 4 is prevented at the same time. When taking crabs, only the sealing mesh plate 8 needs to be twisted to open, and the crabs can be taken from the top of the upper cover plate 1, making it more convenient to take crabs.
