Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crayfish trapping cages, in particular to a crayfish breeding trapping cage. Background Technique
[0002] Crayfish breeding is an aquaculture activity, generally carried out in breeding ponds. During the fishing season, it is necessary to catch and send them to the market. Trapping cages are commonly used equipment for crayfish fishing. In order to facilitate seeing the fishing situation in the trapping cage, the utility model proposes a crayfish breeding trapping cage. Summary of the Invention
[0003] The purpose of the utility model is to provide a crayfish breeding trapping cage to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution. A crayfish breeding trapping cage includes a cage body. The cage body is hollow inside and has a plurality of trapping openings on the side. A plurality of anti-escape sheets inclined towards the inside of the cage body are arranged on the trapping openings. The bottom of the cage body is connected with a bottom cage. The bottom cage is hollow inside and has an opening at the top, and is communicated with the opening formed at the bottom of the cage body. A sliding plate is slidably arranged in the bottom cage. The top of the sliding plate is connected with a sliding rod. One end of the sliding rod is connected with the sliding plate, and the other end passes through the top of the cage body and is slidably connected with the cage body.
[0005] Preferably, the cage body and the bottom cage are connected by threads.
[0006] Preferably, a column is arranged at the top of the cage body. The sliding rod is located inside the column and is slidably connected with the column. A plurality of slots are formed on the side wall of the column.
[0007] Preferably, a marking part is arranged at the top of the sliding rod. The appearance color of the marking part is different from that of the sliding rod and the column.
[0008] Preferably, a fluorescent powder is coated on the outer surface of the marking part.
[0009] Preferably, the outer shell of the cage body is a net structure.
[0010] Preferably, the sliding rod is hollow inside and has an opening at the top.
[0011] Preferably, the bottom of the bottom cage is conical.
[0012] Compared with the prior art, the beneficial effect of the utility model is that by arranging the sliding plate and the sliding rod, after the crayfish enter the cage body, they squeeze the sliding plate and the sliding rod to sink. Through the sinking position of the sliding rod, it is convenient to see the fishing situation of the crayfish in the trapping cage. Brief Description of the Drawings
[0013] Figure 1 This is an internal sectional view of the present utility model.
[0014] In the figure: 1 cage body, 11 trapping openings, 12 anti-escape pieces, 13 upright columns, 14 slots, 2 bottom cage, 3 slide plate, 31 slide rod, 32 marking part. Specific embodiments
[0015] 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 creative efforts shall fall within the protection scope of the present utility model.
[0016] Referring to Fig. (1), a trapping cage for crayfish farming includes a cage body 1. The cage body 1 is hollow inside and has a plurality of trapping openings 11 on the side. A plurality of anti-escape pieces 12 inclined towards the inside of the cage body 1 are provided on the trapping openings 11. The bottom of the cage body 1 is connected to a bottom cage 2. The bottom cage 2 is hollow inside and has an opening at the top, and is communicated with the opening provided at the bottom of the cage body 1. A slide plate 3 is slidably arranged in the bottom cage 2. A slide rod 31 is connected to the top of the slide plate 3. One end of the slide rod 31 is connected to the slide plate 3, and the other end passes through the top of the cage body 1 and is slidably connected to the cage body 1.
[0017] The cage body 1 and the bottom cage 2 are connected by threads. An upright column 13 is provided at the top of the cage body 1. The slide rod 31 is located inside the upright column 13 and is slidably connected to the upright column 13. A plurality of slots 14 are provided on the side wall of the upright column 13. A marking part 32 is provided at the top of the slide rod 31. The outer surface color of the marking part is different from that of the slide rod and the upright column. A fluorescent powder is coated on the outer surface of the marking part 32. The outer shell of the cage body 1 is a mesh structure. The slide rod 31 is hollow inside and has an opening at the top. The bottom of the bottom cage 2 is conical.
[0018] When the device is in use, the bait is placed in the bottom cage 2, and then the bottom cage 2 is installed at the bottom of the cage body 1. Then the cage body 1 is placed in the water bottom, and the bottom cage is inserted into the soil at the water bottom. The part of the slide rod 31 entering the water body gives an upward pull to the slide plate 3 under the action of buoyancy. Crayfish enter the cage body 1 from the trapping openings 11 under the attraction of the bait. As the number of crayfish in the cage body 1 increases, the crayfish squeeze into the bottom cage and squeeze the slide plate 3 to move downward. The slide rod follows the slide plate 3 to move downward, so that the marking part at the top of the slide rod 31 reaches the slots 14 and is observed. The staff can judge the approximate fishing situation by observing the position of the marking part. The fluorescent powder can help observe the position of the marking part at night; in order to prevent the cage body from tipping or moving, a heavy object can be pressed on the top of the cage body.
[0019] The orientation or positional relationship shown in the drawings is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the present invention.
[0020] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.
[0021] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
