Description

Technical Field

[0001] The present invention relates to the technical field of Procambarus clarkii farming, and in particular to a Procambarus clarkii net cage device. Background Art

[0002] Procambarus clarkii, commonly known as crayfish, is an aquatic species with high economic value. It contains high protein, low fat and low calories, and is one of the high-quality aquatic foods. Procambarus clarkii likes dark environments and usually inhabits shallow water areas such as ditches, ponds, lakes, reservoirs, paddy fields, etc., living a benthic life. Therefore, at present, most farmers use net cage devices for artificial breeding of Procambarus clarkii.

[0003] However, the existing net cage devices have a simple structure, mostly composed of woven nets and brackets. Although they can effectively ensure that the Procambarus clarkii in the net cage cannot escape, for long-term breeding, it is impossible to observe the growth of Procambarus clarkii frequently and effectively. Subsequently, it is easy to occur that the Procambarus clarkii die and are not treated in time, resulting in large-scale disease and death, and the breeding benefits cannot be guaranteed.

[0004] To solve the above problems, we propose a Procambarus clarkii net cage device. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the background art, and to propose a Procambarus clarkii net cage device.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A Procambarus clarkii net cage device includes a lower ring plate. Four support rods distributed in a rectangle are fixedly connected to the upper end of the lower ring plate. The upper ends of the four support rods are jointly fixedly connected with an upper ring plate. A metal mesh cover is jointly fixedly connected between the upper ring plate and the lower ring plate. The metal mesh cover is located inside the four support rods. A circular lifting net plate is arranged inside the metal mesh cover. The outer peripheral surface of the lifting net plate is fixedly connected with a metal outer ring plate. The outer peripheral surface of the metal outer ring plate is slidably attached to the inner wall of the metal mesh cover;

[0007] Above the upper ring plate, there is a lifting mechanism. The lifting mechanism includes eight first pulley groups evenly and fixedly connected to the upper end of the upper ring plate. An elevating ring plate is sleeved outside the four support rods. Eight first steel wires evenly distributed in a circumferential manner are fixedly connected to the upper end of the metal outer ring plate. One end of each of the eight first steel wires away from the metal outer ring plate bypasses one of the eight first pulley groups and is fixedly connected to the upper end of the elevating ring plate. The outer end of the lower ring plate is fixedly connected with a pulley box. A second pulley group is arranged in the pulley box. Two spaced fixed plates are fixedly connected to the outer peripheral surface of the upper ring plate at a position above the pulley box. A winding roller is rotatably connected between the two fixed plates. A second steel wire is wound around the winding roller. One end of the second steel wire away from the winding roller penetrates through the pulley box and bypasses the second pulley group in the pulley box. The end of the second steel wire extending out of the pulley box is fixedly connected to the lower end of the elevating ring plate.

[0008] In the above-mentioned Procambarus clarkii net cage device, four magnets distributed in a rectangle are fixedly connected to the inner peripheral wall of the lower ring plate.

[0009] In the above-mentioned Procambarus clarkii net cage device, an annular counterweight block concentric with it is fixedly connected to the lower end of the lifting net plate.

[0010] In the above-mentioned Procambarus clarkii net cage device, the elevating ring plate is made of wood.

[0011] In the above-mentioned Procambarus clarkii net cage device, a rocker coaxial with the winding roller is arranged on one side of the fixed plate. A disc is fixedly sleeved on the rod shaft of the rocker. The disc is spaced from the fixed plate. A bolt penetrates through and is threadedly connected to the disc. One end of the bolt close to the fixed plate is fixedly connected with a rubber block.

[0012] In the above-mentioned Procambarus clarkii net cage device, eight cleaning rings evenly distributed in a circumferential manner are fixedly connected to the inner peripheral wall of the upper ring plate. The eight first steel wires respectively penetrate through the eight cleaning rings.

[0013] In the above-mentioned Procambarus clarkii net cage device, four upper sleeve blocks distributed in a rectangle are fixedly connected to the outer peripheral surface of the upper ring plate. Four lower sleeve blocks corresponding to the positions of the upper sleeve blocks are fixedly connected to the outer peripheral surface of the lower ring plate. A positioning rod is sleeved between the upper and lower corresponding upper sleeve blocks and lower sleeve blocks. The lower ends of the four positioning rods are all conical. The four positioning rods all slide through the elevating ring plate.

[0014] In the above-mentioned Procambarus clarkii net cage device, the four positioning rods are all threadedly connected to the upper sleeve blocks. A rotating block is fixedly sleeved on the upper end of the positioning rod.

[0015] In the above-mentioned Procambarus clarkii cage device, a shrimp taking channel is connected on the outer peripheral surface of the metal mesh cover and above the lifting ring plate, and a box cover is provided on the outer end cover of the shrimp taking channel.

[0016] Compared with the existing technology, the advantages of this crayfish cage device are:

[0017] By arranging the lifting mechanism, when it is necessary to inspect the Procambarus clarkii cultured in the device, it is only necessary to use the rocker to shake the winding roller to wind the second steel wire rope. The second steel wire rope can pull the lifting ring plate downward under the guidance of the second pulley block in the pulley box. When the lifting ring plate moves downward, the first steel wire rope and the first pulley block can be used to pull the lifting mesh plate upward, so that the lifting mesh plate can be stably moved upward along the metal mesh cover, thereby moving the Procambarus clarkii located on the lifting mesh plate to the water surface for observation.

[0018] By setting up the disc, bolts and rubber blocks, after the lifting mesh plate is lifted to the required height through the winding roller and the rocker, you only need to rotate the bolt to press the rubber block against the fixed plate, and then you can use the friction force to lock the rocker, so that the rocker cannot rotate, thereby locking the position height of the lifting mesh plate.

[0019] By setting up a shrimp retrieval channel, when it is necessary to collect the farmed crawfish, the lifting device is used to lift some crawfish to the water surface, and the position of the crawfish is now located at the position of the shrimp retrieval channel. The staff only needs to open the box cover of the shrimp retrieval channel, put on the collection bag, or connect the collection box, and then the crawfish can be effectively driven out of the cage device through the shrimp retrieval channel, which greatly facilitates the harvesting work of the farmers.

[0020] In summary, the present invention can easily inspect the Procambarus clarkii at any time when the Procambarus clarkii is cultured in a cage device, and can also conveniently harvest the Procambarus clarkii when it matures. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0027] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0028] Refer to Figures 1-5 , a Procambarus clarkii net cage device, including a lower ring plate 1. Four support rods 2 distributed in a rectangle are fixedly connected to the upper end of the lower ring plate 1. The upper ends of the four support rods 2 are jointly fixedly connected with an upper ring plate 3. The upper ring plate 3, the lower ring plate 1 and the support rods 2 jointly form the basic framework of the net cage device. A metal mesh cover 4 is fixedly connected between the upper ring plate 3 and the lower ring plate 1. The metal mesh cover 4 is located inside the four support rods 2. The metal mesh cover 4 plays a role in preventing the Procambarus clarkii in the net cage device from escaping. And the metal mesh cover 4 is made of stainless steel material, which is not easy to corrode and damage and has a very high service life. A circular lifting mesh plate 5 is arranged inside the metal mesh cover 4. The lifting mesh plate 5 is also made of stainless steel material. The outer peripheral surface of the lifting mesh plate 5 is fixedly connected with a metal outer ring plate 6. The outer peripheral surface of the metal outer ring plate 6 is slidably attached to the inner wall of the metal mesh cover 4. The fitting of the metal outer ring plate 6 and the metal mesh cover 4 plays a limiting role, enabling it to effectively lift vertically inside the metal mesh cover 4.

[0029] Four magnets 7 distributed in a rectangle are fixedly connected to the inner peripheral wall of the lower ring plate 1. It should be noted that the metal outer ring plate 6 has ferromagnetism and can be adsorbed by the magnets 7. Then, when the lifting mesh plate 5 is at the lowest end of the metal mesh cover 4, the metal outer ring plate 6 can be firmly adsorbed by the four magnets 7, so that it will not move due to the action of water flow. A ring-shaped counterweight 11 concentric with it is fixedly connected to the lower end of the lifting mesh plate 5, playing a role in increasing the weight.

[0030] Above the upper ring plate 3, there is a lifting mechanism. The lifting mechanism includes eight first pulley groups 8 evenly and fixedly connected to the upper end of the upper ring plate 3. Each pulley group consists of two pulleys, which is prior art and will not be described here. A lifting ring plate 9 is sleeved outside the four support rods 2. The upper end of the metal outer ring plate 6 is fixedly connected with eight first steel wires 10 evenly distributed in a circumferential manner. One end of each of the eight first steel wires 10 far from the metal outer ring plate 6 bypasses the eight first pulley groups 8 respectively and is fixedly connected to the upper end of the lifting ring plate 9. The lifting ring plate 9 is made of wood. Under the action of the wood material, when the lifting ring plate 9 is in water, it always has an upward moving tendency under the action of water buoyancy. Then, under the connection action of the first pulley groups 8 and the first steel wires 10, the lifting net plate 5 can always be kept at the bottom of the metal net cover 4. Then, Procambarus clarkii can be cultured in the metal net cover 4.

[0031] The outer end of the lower ring plate 1 is fixedly connected with a pulley box 12. A second pulley group is arranged in the pulley box 12. On the outer peripheral surface of the upper ring plate 3 and at a position above the pulley box 12, two spaced fixed plates 13 are fixedly connected. A winding roller 14 is rotatably connected between the two fixed plates 13. A second steel wire 16 is wound around the winding roller 14. One end of the second steel wire 16 far from the winding roller 14 penetrates through the pulley box 12 and bypasses the second pulley group in the pulley box 12. The end of the second steel wire 16 extending out of the pulley box 12 is fixedly connected to the lower end of the lifting ring plate 9. A rocker 15 coaxially and fixedly connected with the winding roller 14 is arranged on one side of the fixed plate 13. The winding roller 14 can be shaken through the rocker 15 to wind the second steel wire 16.

[0032] Specifically, when it is necessary to check the Procambarus clarkii cultured in the device, only need to shake the winding roller 14 through the rocker 15 to wind the second steel wire 16. Under the guiding action of the second pulley group in the pulley box 12, the second steel wire 16 can pull the lifting ring plate 9 downward. When the lifting ring plate 9 moves downward, the first steel wire 10 and the first pulley group 8 can be used to pull the lifting net plate 5 upward, so that the lifting net plate 5 moves upward stably along the metal net cover 4, and the Procambarus clarkii on the lifting net plate 5 can be moved to the water surface for observation.

[0033] A disc 17 is fixedly sleeved on the shaft of the rocker 15. The disc 17 is spaced from the fixed plate 13. A bolt 18 penetrates through and is threadedly connected to the disc 17. One end of the bolt 18 close to the fixed plate 13 is fixedly connected with a rubber block. Through the arrangement of the disc 17 and the bolt 18, after the lifting net plate 5 is lifted to the required height through the winding roller 14 and the rocker 15, only need to rotate the bolt 18 to press the rubber block against the fixed plate 13, and the rocker 15 can be locked by the action of friction, so that the rocker cannot rotate, and thus the position height of the lifting net plate 5 is locked.

[0034] Eight cleaning rings 19 are fixedly connected to the inner peripheral wall of the upper ring plate 3 and are evenly distributed in a circumferential manner. Eight first steel wire ropes 10 respectively pass through the eight cleaning rings 19. While the cleaning rings 19 limit the first steel wire ropes 10, they can clean the sundries on the surface of the first steel wire ropes 10, effectively preventing the influence of waterweeds on the first pulley set 8.

[0035] Four upper sleeve blocks 20 distributed in a rectangle are fixedly connected to the outer peripheral surface of the upper ring plate 3. Four lower sleeve blocks 21 corresponding to the positions of the upper sleeve blocks 20 are fixedly connected to the outer peripheral surface of the lower ring plate 1. A positioning rod 22 is jointly sleeved between the upper sleeve block 20 and the lower sleeve block 21 corresponding up and down. The lower ends of the four positioning rods 22 are all conical. The four positioning rods 22 all slide through the lifting ring plate 9. The four positioning rods 22 play a role in limiting the lifting ring plate 9, enabling it to stably lift and lower vertically without tilting.

[0036] The four positioning rods 22 are all threadedly connected to the upper sleeve blocks 20. A rotating block 23 is fixedly sleeved on the upper end of the positioning rod 22. By rotating the corresponding positioning rod 22 through the rotating block 23, the positioning rod 22 can be vertically moved, which is convenient for inserting the lower end of the corresponding positioning rod 22 into the water bottom when installing this net cage device, further ensuring the stability of the net cage device.

[0037] A shrimp-taking channel 24 is communicated on the outer peripheral surface of the metal mesh cover 4 and above the lifting ring plate 9. The outer end of the shrimp-taking channel 24 is covered with a box cover. The setting of the shrimp-taking channel 24 is convenient for collecting the Procambarus clarkii after the breeding is completed. When using the lifting device to lift the Procambarus clarkii to the water surface, the position of the Procambarus clarkii is just at the position of the shrimp-taking channel 24 at this time. The staff only needs to open the box cover of the shrimp-taking channel 24, set a collection bag, or connect a collection box, and then can effectively drive the Procambarus clarkii out of the net cage device from the shrimp-taking channel 24, greatly facilitating the harvesting work of the farmers.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
