Description

Technical Field

[0001] This utility model relates to the field of ground cage technology, and in particular to a ground cage. Background Technology

[0002] Fish traps are common tools for aquaculture and fishing. They are usually made of nylon netting or galvanized iron wire, with a metal / plastic frame to form a mesh trap. They have an entrance with barbed edges and a closed collection chamber. The barbed edges prevent fish, shrimp, and crabs from escaping. They are suitable for freshwater ponds, rivers, lakes, and other similar environments. When in use, they sink to the bottom and are guided into the water by the migratory or foraging habits of aquatic organisms. They can be used to catch small aquatic animals or to screen fry in aquaculture.

[0003] Currently, there are two types of fish traps on the market: one is a foldable long strip fish trap structure, and the other is an unfoldable foldable fish trap structure. The foldable long strip fish trap structure has a long strip of netting as its core, and the main body is made of high-tenacity nylon netting. The inside has multiple sets of entrances with barbed tassels spaced along the length, and the end is connected to a closed collection compartment. The sides of the netting are embedded with bendable segmented support members, which are mostly galvanized iron wire or plastic rods. The support members can be folded or rolled up along the length of the netting. When folded, the volume is greatly reduced, making it easy to carry. When unfolded, it relies on the support members to maintain its long strip shape. The unfoldable foldable fish trap structure uses a thinner and denser nylon material for the main netting. The support frame is detachable or hinged and uses metal or plastic rods with horizontal and vertical bars. The vertical bars are combined with the horizontal bars by buckles or elastic ropes. When unfolded, it can be assembled into rectangular, polygonal, or other shapes as needed. Some models have adjustable compartments. When folding, first disassemble or fold the support frame, and then roll the netting into a compact ball. The edges of the netting often have storage ropes for easy fixation.

[0004] However, for the two types of traps currently in use, the entrance to the trap and the space where the aquatic creatures are located after entering the trap are always in the same space. When there are already aquatic creatures in the space where the aquatic creatures are located in the trap, when aquatic creatures enter later, they may struggle because they cannot leave the trap or fight because there is not enough space. This will cause some of the aquatic creatures in the trap to die, ultimately making it impossible for the user to ensure a harvest when retrieving the trap.

[0005] Therefore, a ground cage is proposed to solve or alleviate the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a ground cage.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A cage includes an upper cage frame and a lower cage frame that are fixedly connected and have interconnected internal spaces. The upper and lower cage frames are provided with cage nets on their outer sides, and the upper cage frame has an opening on its side away from the lower cage frame. The upper cage frame located at the opening is connected to a cage door frame with an inner ring of cage nets to block the opening. The internal space of the upper cage frame is larger than the internal space of the lower cage frame. The cage net located on the outer side of the lower cage frame extends inward to form several horn-shaped inlets that communicate with the internal space of the lower cage frame.

[0008] Preferably, the lower cage frame has a columnar structure, and several of the horn inlets located on the outer side of the lower cage frame are evenly spaced.

[0009] Preferably, the lower cage frame has a cylindrical structure.

[0010] Preferably, the lower cage frame is a regular polygonal column structure with an even number of sides. The number of the horn inlets located on the outer side of the lower cage frame is half the number of sides of the lower cage frame, and the horn inlets located on the outer side of the lower cage frame are spaced apart on the outer surface of the lower cage frame.

[0011] Preferably, the upper cage frame includes a plurality of vertical rods and horizontal rods, the lower ends of the plurality of vertical rods are fixedly connected to the top of the lower cage frame, and the number of vertical rods is at least three, and the horizontal rods are fixedly connected to the upper ends of the vertical rods.

[0012] Preferably, the inner ring of the crossbar forms an opening.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] A cage includes an upper cage frame 2 and a lower cage frame 1 that are fixedly connected and have interconnected internal spaces. The upper cage frame 2 and the lower cage frame 1 are provided with cage nets on their outer sides. The upper cage frame 2 has an opening on its side away from the lower cage frame 1. The upper cage frame 2 located at the opening is connected to a cage door frame 3 with an inner ring of cage nets to block the opening. The internal space of the upper cage frame 2 is larger than the internal space of the lower cage frame 1. The cage nets located on the outer side of the lower cage frame 1 extend inward to form several horn-shaped inlets that communicate with the internal space of the lower cage frame 1. The lower cage frame 1 has a columnar structure. Several horn-shaped inlets located on the outer side of the lower cage frame 1 are evenly spaced. The cross-section of the upper cage frame 2 gradually decreases from bottom to top. The upper cage frame 2 includes several vertical rods 201 and horizontal rods 202. The lower ends of the several vertical rods 201 are fixedly connected to the top of the lower cage frame 1, and the number of vertical rods 201 is at least three. The horizontal rods 202 are fixedly connected to the upper ends of the vertical rods 201.

[0028] In practical application, the opening of the upper cage frame 2 is closed by the cage door frame 3, and the two are detachably connected. Then, the user puts the entire cage into the water. Since the cross-sectional area of ​​the upper cage frame 2 in the cage gradually decreases from bottom to top, when the cage is submerged in the water, the upper part of the cage will not occupy a large area, and it can be relatively concealed in the water, avoiding occupying a large water surface area and avoiding being too conspicuous.

[0029] When aquatic organisms swim, they can enter the space of the lower cage 1 through the funnel-shaped inlet of the upper cage net. Due to the design of the funnel-shaped inlet, the initial swimming channel is large when aquatic organisms enter the lower cage 1, and the swimming channel gradually narrows thereafter. When aquatic organisms try to leave the lower cage 1, they have difficulty leaving through the small port of the funnel-shaped inlet. In order to avoid a large accumulation of aquatic organisms in the internal space of the lower cage 1, the upper cage 2, which is connected to the lower cage 1, works together to provide aquatic organisms with sufficient space to swim. In addition, when aquatic organisms fight with each other inside, there is also enough space for them to hide, thereby ensuring that aquatic organisms will not struggle, fight and die due to being confined in a crowded environment, thus ensuring the quality of the final aquatic product harvest.

[0030] When a user needs to harvest the aquatic products from the trap, they can open the trap door 3, which opens the opening on the upper trap 2, allowing the user to directly reach inside and retrieve the aquatic products. Alternatively, if the user does not wish to retrieve them manually, they can pour the aquatic products out. This method differs from the conventional trap openings, which are cylindrical nets that are manually knotted to close. When pouring out the aquatic products, some will hang on the net at the opening and still need to be manually removed. However, due to this design, it is difficult for the user to reach inside and retrieve the aquatic products. Forcibly removing them would damage both the aquatic products and the net. This improved trap, with its opening serving as the trap opening, avoids this problem to some extent.
