Description

Technical Field

[0001] The invention relates to the technical field of Procambarus clarkii breeding, 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 is high in protein, low in fat and calories, and is one of the high-quality aquatic delicacies. Procambarus clarkii likes dark environments and usually lives in shallow waters such as ditches, ponds, lakes, reservoirs, and rice fields, leading a benthic life. Therefore, most farmers currently use cage devices to artificially cultivate Procambarus clarkii.

[0003] However, the existing cage device has a simple structure, and most of them are composed of woven nets and brackets. Although it can effectively ensure that the crayfish in the cage cannot escape, it is impossible to frequently and effectively observe the growth of the crayfish for a long time. As a result, the death of the crayfish is likely to occur and if it is not handled in time, it will lead to large-scale mortality, and the breeding benefits cannot be guaranteed.

[0004] In order to solve the above problems, we proposed a crayfish cage device. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the background technology and to propose a crayfish cage device.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a crayfish cage device, comprising a lower ring plate, the upper end of which is fixedly connected to four support rods distributed in a rectangular shape, the upper ends of the four support rods are commonly fixedly connected to an upper ring plate, a metal mesh cover is commonly fixedly connected between the upper ring plate and the lower ring plate, the metal mesh cover is located on the inner side of the four support rods, a circular lifting mesh plate is arranged inside the metal mesh cover, the outer peripheral surface of the lifting mesh plate is fixedly connected to a metal outer ring plate, and the outer peripheral surface of the metal outer ring plate is slidably fitted with the inner wall of the metal mesh cover;

[0007] The top of the upper ring plate is provided with a lifting mechanism, and the lifting mechanism includes eight first pulley blocks evenly fixedly connected to the upper end of the upper ring plate, and the outer sides of the four support rods are jointly sleeved with a lifting ring plate, and eight first steel wire ropes are fixedly connected to the upper end of the metal outer ring plate, and one end of the eight first steel wire ropes away from the metal outer ring plate respectively passes through the eight first pulley blocks and is fixedly connected to the upper end of the lifting ring plate, and the outer end of the lower ring plate is fixedly connected to the pulley box, and a second pulley block is provided in the pulley box. The outer peripheral surface of the upper ring plate and the position above the pulley box are fixedly connected with two intervally arranged fixed plates, and a winding roller is rotatably connected between the two fixed plates. The second steel wire rope is wound on the winding roller, and one end of the second wire rope away from the winding roller passes through the pulley box and passes through the second pulley block in the pulley box, and one end of the second steel wire rope extending out of the pulley box is fixedly connected to the lower end of the lifting ring plate.

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

[0009] In the above-mentioned Procambarus clarkii cage device, the lower end of the lifting mesh plate is fixedly connected to a ring-shaped counterweight block arranged concentrically therewith.

[0010] In the above-mentioned Procambarus clarkii cage device, the lifting ring plate is made of wooden material.

[0011] In the above-mentioned crayfish cage device, a rocker is provided on one side of the fixed plate and is coaxially fixedly connected to the winding roller. A disc is fixedly sleeved on the rod shaft of the rocker. The disc is spaced apart from the fixed plate. A bolt passes through and is threadedly connected to the disc. A rubber block is fixedly connected to one end of the bolt close to the fixed plate.

[0012] In the above-mentioned Procambarus clarkii cage device, eight cleaning rings evenly distributed circumferentially are fixedly connected to the inner peripheral wall of the upper ring plate, and the eight first steel wire ropes are respectively arranged through the eight cleaning rings.

[0013] In the above-mentioned crayfish cage device, four upper blocks distributed in a rectangular shape are fixedly connected to the outer peripheral surface of the upper ring plate, and four lower blocks corresponding to the positions of the upper blocks are fixedly connected to the outer peripheral surface of the lower ring plate. Positioning rods are commonly sleeved between the upper and lower corresponding blocks, and the lower ends of the four positioning rods are all conical. The four positioning rods are all slidably penetrated through the lifting ring plate.

[0014] In the above-mentioned Procambarus clarkii cage device, the four positioning rods are all threadedly connected to the upper sleeve block, and the upper ends of the positioning rods are fixedly sleeved with a rotating block.

[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 DESCRIPTION

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

[0028] Reference Figure 1-Figure 5 A crayfish cage device includes a lower ring plate 1, and four rectangularly distributed support rods 2 are fixedly connected to the upper end of the lower ring plate 1. The upper ends of the four support rods 2 are commonly fixedly connected to an upper ring plate 3. The upper ring plate 3, the lower ring plate 1 and the support rods 2 together form the basic structure of the cage device. A metal mesh cover 4 is commonly fixedly connected between the upper ring plate 3 and the lower ring plate 1. The metal mesh cover 4 is located on the inner side of the four support rods 2. The metal mesh cover 4 plays a role in preventing the crayfish in the cage device from escaping. The metal mesh cover 4 is made of stainless steel material, which is not easy to be corroded and damaged, and has a very long service life. A circular lifting mesh plate 5 is arranged inside the metal mesh cover 4, and the lifting mesh plate 5 is also made of stainless steel material. A metal outer ring plate 6 is fixedly connected to the outer peripheral surface of the lifting mesh plate 5. The outer peripheral surface of the metal outer ring plate 6 is slidably fitted with the inner wall of the metal mesh cover 4. The metal outer ring plate 6 fits with the metal mesh cover 4 to play a limiting role, so that it can be effectively lifted and lowered vertically in the metal mesh cover 4.

[0029] Four magnets 7 distributed in a rectangular shape are fixedly connected to the inner 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 located at the bottom 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 the water flow. The lower end of the lifting mesh plate 5 is fixedly connected to a concentric annular counterweight block 11, which plays a role in increasing weight.

[0030] A lifting mechanism is provided above the upper ring plate 3, and the lifting mechanism includes eight first pulley blocks 8 evenly fixedly connected to the upper end of the upper ring plate 3. The pulley block is composed of two pulleys, which is a prior art and will not be described here. A lifting ring plate 9 is commonly sleeved on the outer side of the four support rods 2, and eight first steel wire ropes 10 evenly distributed in a circumferential manner are fixedly connected to the upper end of the metal outer ring plate 6. The ends of the eight first steel wire ropes 10 away from the metal outer ring plate 6 respectively pass around the eight first pulley blocks 8 and are fixedly connected to the upper end of the lifting ring plate 9. The lifting ring plate 9 is made of wood material. Under the action of the wood material, the lifting ring plate 9 can always have an upward movement tendency under the action of water buoyancy when it is in the water. Then, under the connection of the first pulley block 8 and the first steel wire rope 10, the lifting mesh plate 5 can always remain at the bottom of the metal mesh cover 4, and then the crayfish can be cultured in the metal mesh cover 4.

[0031] The outer end of the lower ring plate 1 is fixedly connected to a pulley box 12, and a second pulley block is arranged in the pulley box 12. Two intervally arranged fixed plates 13 are fixedly connected to the outer peripheral surface of the upper ring plate 3 and at a position above the pulley box 12. A winding roller 14 is connected and rotated together between the two fixed plates 13. A second steel wire rope 16 is wound around the winding roller 14. One end of the second steel wire rope 16 away from the winding roller 14 passes through the pulley box 12 and bypasses the second pulley block in the pulley box 12. One end of the second steel wire rope 16 extends out of the pulley box 12 and is fixedly connected to the lower end of the lifting ring plate 9. A rocker 15 coaxially fixedly connected to the winding roller 14 is provided on one side of the fixed plate 13. The winding roller 14 can be shaken by the rocker 15 to carry out the winding of the second steel wire rope 16.

[0032] Specifically, when it is necessary to inspect the Procambarus clarkii cultured in the device, it is only necessary to rock the winding roller 14 through the rocker 15 to face the second steel wire rope 16 for winding. Under the guidance of the second pulley block in the pulley box 12, the second steel wire rope 16 can pull the lifting ring plate 9 downward. When the lifting ring plate 9 moves downward, the first steel wire rope 10 and the first pulley block 8 can be used to pull the lifting mesh plate 5 upward, so that the lifting mesh plate 5 can be stably moved upward along the metal mesh cover 4, so that the Procambarus clarkii located on the lifting mesh plate 5 is moved to the water surface for observation.

[0033] A disc 17 is fixedly sleeved on the rod shaft of the rocker 15, and the disc 17 is spaced apart from the fixed plate 13. A bolt 18 passes through the disc 17 and is threadedly connected. A rubber block is fixedly connected to one end of the bolt 18 close to the fixed plate 13. Through the arrangement of the disc 17 and the bolt 18, after the lifting mesh plate 5 is lifted to the required height by the winding roller 14 and the rocker 15, it is only necessary to rotate the bolt 18 to press the rubber block against the fixed plate 13, so that the rocker 15 can be locked by the friction force, so that the rocker cannot rotate, thereby locking the position height of the lifting mesh plate 5.

[0034] Eight cleaning rings 19 evenly distributed on the inner wall of the upper ring plate 3 are fixedly connected, and the eight first steel wire ropes 10 respectively pass through the eight cleaning rings 19. The cleaning rings 19 can not only limit the position of the first steel wire ropes 10, but also clean the debris on the surface of the first steel wire ropes 10, thereby effectively preventing the influence of aquatic plants on the first pulley group 8.

[0035] Four upper blocks 20 distributed in a rectangular shape are fixedly connected to the outer circumference of the upper ring plate 3, and four lower blocks 21 corresponding to the positions of the upper blocks 20 are fixedly connected to the outer circumference of the lower ring plate 1. Positioning rods 22 are commonly sleeved between the upper and lower blocks 20 and 21 corresponding to each other. The lower ends of the four positioning rods 22 are all conical. The four positioning rods 22 are all slidably penetrated through the lifting ring plate 9. The four positioning rods 22 serve to limit the lifting ring plate 9, so that it can be lifted and lowered stably without tilting.

[0036] The four positioning rods 22 are all threadedly connected to the upper sleeve block 20. The upper end of the positioning rod 22 is fixedly sleeved with a rotating block 23. The corresponding positioning rod 22 can be rotated by the rotating block 23, so that the positioning rod 22 can move vertically. This makes it convenient to insert the lower end of the corresponding positioning rod 22 into the bottom of the water when installing the cage device, thereby further ensuring the stability of the cage device.

[0037] A shrimp taking channel 24 is connected to the outer circumferential surface of the metal mesh cover 4 and above the lifting ring plate 9. The outer end cover of the shrimp taking channel 24 is provided with a box cover. The setting of the shrimp taking channel 24 is convenient for collecting the cultivated crawfish. When it is necessary to use a lifting device to lift some crawfish to the water surface, and at this time, the position of the crawfish is located at the position of the shrimp taking channel 24. The staff only needs to open the box cover of the shrimp taking channel 24, put on a collecting bag, or connect the collecting box, and the crawfish can be effectively driven out of the cage device from the shrimp taking channel 24, which greatly facilitates the harvesting work of the farmers.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
