Description

Technical Field

[0001] The utility model relates to the technical field of bullfrog breeding, and particularly relates to a bullfrog breeding barrel which is convenient for discharging feces. Background Technique

[0002] At present, during the process of bullfrog breeding, since bullfrogs are bred in water tanks such as earthen ponds, their excreta and impurities such as molt generated during the growth process are directly dissolved in water, resulting in a large number of germs in the water quality, so that the water needs to be changed frequently. When changing the water source of the current breeding containers, generally, it is necessary to completely drain them before they can be cleaned. However, for breeding tanks such as earthen ponds, it is relatively difficult to completely drain them without affecting the activities of bullfrogs. At the same time, the existing aquaculture sewage management departments are becoming more and more strict with sewage management. For example, in Zhejiang region, basically, strict treatment of sewage discharge is required, which increases the breeding difficulty. For the above reasons, the following problems exist in current bullfrog breeding:

[0003] 1. Generally, the breeding containers are large, with high requirements for the site and high breeding costs. When the breeding device needs to be replaced, the replacement cost is high. When changing the water source in the breeding device, only after completely draining the water can the excreta and other substances at the bottom be cleaned. The replacement time is long and the cost is high. It is not easy to quickly change the water and maintain the safety of the water quality, so it is necessary to regularly disinfect the water quality, with high costs and relatively poor health of the bullfrogs themselves.

[0004] 2. It is difficult to completely discharge the excreta and frog skins. Generally, manual rinsing is required. During the rinsing process, since bullfrogs gather at the bottom of the container, they are prone to collide with each other and get injured, resulting in an increase in the proportion of diseased frogs. Moreover, the existing breeding methods generally require regular disinfection of bullfrogs in addition to treating external injuries, which must use antibiotics. When people eat them, it is easy to cause potential health hazards. Summary of the Invention

[0005] In order to solve certain or some technical problems existing in the prior art, the purpose of this application is to provide a bullfrog breeding barrel which is convenient for discharging feces, which can solve the problems of inability to clean the water tank and troublesome replacement of breeding water, making it not easy to cause damage to bullfrogs when changing the water quality, reducing or avoiding the use of antibiotic drugs, having a stable growth environment, a stable growth cycle, convenient construction of breeding facilities and low costs, and being easy to promote.

[0006] To solve the above-mentioned existing technical problems, the present application adopts the following technical solutions to achieve:

[0007] A bullfrog breeding barrel facilitating feces discharge, comprising a bracket, a barrel body arranged on the bracket, a water outlet arranged at the bottom of the barrel body, and an adjusting support plate arranged inside the barrel body. The adjusting support plate is provided with grid holes, the size of the grid holes can be adjusted by the adjusting support plate, and a sewage receiving cavity is formed between the adjusting support plate and the bottom of the barrel body. Impurities excreted into the water precipitate into the sewage receiving cavity through the grid holes.

[0008] Preferably, the adjusting support plate comprises an upper partition plate and a lower partition plate, a rotating mechanism arranged between the upper partition plate and the lower partition plate, and an adjusting mechanism arranged between the upper partition plate and the lower partition plate. The grid holes comprise first mesh holes arranged on the upper partition plate and second mesh holes arranged on the lower partition plate. The opening size of the first mesh holes can be adjusted by rotating the lower partition plate through the adjusting mechanism.

[0009] Preferably, the rotating mechanism comprises a rotating shaft protruding upward in the middle of the lower partition plate and a rotating hole arranged in the middle of the upper partition plate. The upper partition plate is sleeved on the rotating shaft through the rotating hole.

[0010] Preferably, the adjusting mechanism comprises a limiting convex block arranged on the lower partition plate, a limiting hole arranged on the upper partition plate, and a driving handle arranged on the upper partition plate. The limiting convex block is sleeved in the limiting hole, and the size of the grid holes is driven and adjusted by the driving handle.

[0011] Preferably, a circle of the limiting holes is arranged around the outer ring of the first mesh holes, and the limiting convex block is connected by inserting into one of the limiting holes. The driving handle is an n-shaped structure protruding upward and bending.

[0012] Preferably, both the first mesh holes and the second mesh holes are composed of a plurality of arc-shaped holes distributed in concentric circles.

[0013] Preferably, both the upper partition plate and the lower partition plate are composed of a plurality of fan-shaped grid plates, and adjacent two grid plates are connected by a pin shaft or fixed by a buckle.

[0014] Preferably, a circle of inwardly protruding towing rings is arranged on the inner side of the barrel body, and the bottom of the adjusting support plate is supported and positioned by the towing rings.

[0015] Preferably, the water outlet is located in the middle of the barrel body, a supporting platform protruding upward is arranged inside the water outlet, the adjusting support plate is arranged on the supporting platform, and a circle of metal mesh is arranged around the side surface of the supporting platform.

[0016] Preferably, a circle of flushing mechanisms is arranged around the bottom of the barrel body, and attachments adhered to the bottom of the barrel body are subjected to high-pressure flushing through the flushing mechanisms.

[0017] Preferably, the flushing mechanism includes a shunt pipe arranged in a circle at the bottom of the barrel body, several high-pressure nozzles arranged on the shunt pipe, and at least three water inlet pipes arranged at the bottom of the barrel body and communicated with the shunt pipe. The shunt pipe is supported and fixed at the bottom of the barrel body through the water inlet pipes, and manual switch valves are arranged on each of the water inlet pipes outside the barrel body.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. The breeding barrel takes the barrel body suspended and fixed by the bracket as the main body, with lower requirements for the flatness of the installation ground of the barrel body. It can be arbitrarily adjusted according to the actual number of breeding barrels that can be built, with high flexibility. The cost of the whole set of breeding equipment is low and it is easy to promote. For small enterprises or individual businesses, it can effectively increase income in the existing environment and also provide more conditions for employment.

[0020] 2. When replacing the water in the breeding barrel, the discharge of the internal water source is more convenient, and the problem that the sewage in the barrel body cannot be quickly discharged can be avoided. Especially when an adjusting tray with grid holes is installed in the barrel body, the size of the grid holes can be adjusted through the adjusting tray. A sewage receiving cavity is formed between the adjusting tray and the bottom of the barrel body. During the breeding process, excess feed and impurities excreted into the water can precipitate into the sewage receiving cavity through the grid holes. When replacing the water quality in the barrel body, both the rapid replacement of all the water quality and the partial rapid replacement of the water quality in the bottom sewage receiving cavity can be realized, so that the hygiene of the water quality can be maintained more conveniently and the water quality can be replaced more frequently. The sewage containing impurities such as feed and feces discharged during the breeding process can also be directly discharged into the breeding lake for automatic digestion and purification by aquatic organisms, solving the problem of difficult sewage treatment.

[0021] 3. Compared with other current styles and modes, after breeding with the system, generally, only by discharging the water quality in the sewage receiving cavity and replenishing water, the breeding process can avoid the breeding of bacteria in the water, thus preventing the bullfrogs from getting sick during the breeding process, and also eliminating the use of antibiotics, making the bullfrog meat healthier. Moreover, when replacing the water quality, the bullfrogs can be supported by the adjusting tray, so that the bottom of the barrel will not cause damage to the bullfrogs during cleaning, making them less likely to get sick. For occasional injuries caused by fighting for food, only spraying and disinfecting with compound iodine is required, so as to achieve the purpose of disease-free breeding of bullfrogs during the breeding process.

It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and do not limit the number of objects.

[0028] As Figure 1 shown, a bullfrog breeding barrel facilitating feces discharge includes a support 1, a barrel body 8 provided on the support 1, a water outlet 18 provided at the bottom of the barrel body 8, and an adjusting support plate 11 provided in the barrel body 8. Grid holes 12 are provided on the adjusting support plate 11, and the size of the grid holes 12 can be adjusted by the adjusting support plate 11. The adjusting support plate 11 and the bottom of the barrel body 8 form a sewage receiving cavity 3, and impurities excreted into the water precipitate into the sewage receiving cavity 3 through the grid holes 12.

[0029] During the breeding process of bullfrogs, the breeding barrels are generally placed in a greenhouse. Water is injected into the breeding barrels through a water supply mechanism. The barrel body 8 of the breeding barrel is generally about 6 meters in diameter and 1.5 meters in depth. It drains water in the middle of the bottom, with an area of about 28 ㎡ and a maximum water capacity of 42m 3 , taking the barrel body 8 suspended and fixed by the bracket 1 as the main body. The barrel body 8 is sealed with a canvas waterproof cloth inside. The requirement for the flatness of the installation ground of the barrel body 8 is lower, and the application range is wider. Moreover, the requirement for the sealing of the barrel body 8 is low, and the overall manufacturing cost is low. It is more convenient to increase or reduce the breeding barrels. When replacing the water in the breeding barrel, the discharge of the internal water source is more convenient, and the problem that the sewage in the barrel body 8 cannot be quickly discharged can be avoided. Especially, an adjusting tray 11 with grid holes 12 is installed inside the barrel body 8. The size of the grid holes 12 can be adjusted through the adjusting tray 11. A sewage receiving cavity 3 is formed between the adjusting tray 11 and the bottom of the barrel body 8. During the breeding process, the excess feed and impurities excreted into the water can precipitate into the sewage receiving cavity 3 through the grid holes 12. When replacing the water quality in the barrel body 8, both the rapid replacement of all the water quality and the partial rapid replacement of the water quality in the bottom sewage receiving cavity 3 can be realized, so that the hygiene of the water quality can be maintained more conveniently and the water quality can be replaced more frequently. Compared with other structures, generally, only by discharging the water quality in the sewage receiving cavity 3 and replenishing water, the breeding of bacteria in the water can be avoided, so as to avoid the occurrence of diseases in bullfrogs during the breeding process, and the use of antibiotics is also eliminated, making the meat of bullfrogs healthier. Moreover, when replacing the water quality, the bullfrogs can be supported by the adjusting tray 11, so that the barrel bottom will not cause damage to the bullfrogs during cleaning, making them less likely to get sick. For the occasional injuries caused by scrambling for food, only spraying and disinfecting with compound iodine is needed, so as to achieve the purpose of disease-free breeding of bullfrogs during the breeding process.

[0030] This breeding barrel is generally used in combination with a fish pond for breeding. During the breeding process, the sewage containing impurities such as feed and feces can be directly discharged into the breeding lake for automatic digestion and purification by aquatic organisms, solving the problem of difficult sewage treatment. The breeding environment can be arbitrarily adjusted according to the actual number of breeding barrels that can be built, with high flexibility. The cost of the whole set of breeding equipment is low and it is easy to promote. For small enterprises or individual businesses, it can effectively increase income in the existing environment and also provide more conditions for employment.

[0031] Further improved, the adjustment support plate 11 includes an upper partition 5 and a lower partition 4, a rotating mechanism 7 arranged between the upper partition 5 and the lower partition 4, and an adjustment mechanism 6 arranged between the upper partition 5 and the lower partition 4, and the grid hole 12 includes a first mesh hole 21 arranged on the upper partition 5 and a second mesh hole 23 arranged on the lower partition 4, and the opening size of the first mesh hole 21 can be adjusted by rotating the lower partition 4 by the adjustment mechanism 6.

[0032] The adjustment support plate 11 is composed of an upper partition plate 5 and a lower partition plate 4 that can rotate with each other. The overall structure is simpler. When adjusting the size of the grid hole 12, it is only necessary to rotate the upper partition plate 5 or the lower partition plate 4 through the adjustment mechanism 6 to adjust the size of the passable space between the first mesh hole 21 and the second mesh hole 23, thereby solving the problem of the troublesome adjustment of the grid hole 12. For example, when the first mesh hole 21 and the second mesh hole 23 overlap, the grid hole 12 is in the maximum state; when the first mesh hole 21 and the second mesh hole 23 are misaligned, the mesh of the overlapping part is the mesh hole 12 that can actually pass through; when the first mesh hole 21 and the second mesh hole 23 are completely misaligned, the first mesh hole 21 and the second mesh hole 23 are blocked by the lower partition plate 4 and the upper partition plate 5 respectively. Among them, when the size of the bullfrog reaches different levels, the size of the grid hole 12 can be adjusted by the adjustment mechanism 6 to adapt to different growth needs. When breeding bullfrog seedlings, the first mesh 21 and the second mesh 23 are misaligned to prevent the seedlings from entering the sewage chamber 3 from the grid hole 12 upstream, and when the bullfrog grows up, the grid hole 12 can be enlarged to make feces, physical objects, molting and other materials fall into the sewage chamber 3 as much as possible. By switching the size of the grid hole 12, impurities can be prevented from accumulating on the adjustment support plate 11. When it is necessary to partially change the water, the first mesh 21 and the second mesh 23 can be blocked from each other to form a relatively closed cavity in the sewage chamber 3. When draining, the water in the sewage chamber 3 can be completely discharged first, and the substances that are easy to breed bacteria are prevented from being retained in the barrel 8 for a long time to cause water pollution. When changing, it is more targeted, and the discharge of impurities can be achieved without completely changing the water quality. When changing the water quality, it will not cause damage to the bullfrog, and it can achieve non-injury water change, reduce or avoid the frequency of use of antibiotics, and make the bullfrog meat healthier.

[0033] Further improvement is as follows: Figure 2 As shown, the rotating mechanism 7 includes a rotating shaft 25 protruding upwardly and arranged in the middle of the lower partition 4, and a rotating hole 20 arranged in the middle of the upper partition 5, and the upper partition 5 is sleeved on the rotating shaft 25 through the rotating hole 20.

[0034] The lower partition plate 4 and the upper partition plate 5 are connected by a rotating shaft 25. The overall structure is simple, the assembly is convenient, the production cost is low, and the replacement of the upper partition plate 5 is more convenient. By simply replacing the upper partition plate 5, the size of the first mesh hole 21 can be switched. When the upper partition plate 5 is not replaced, the actual aperture size of the water flow that can pass through the first mesh hole 21 can also be adjusted by the relative rotation of the upper partition plate 5 and the lower partition plate 4, effectively solving the problem of the complex structure of the existing device.

[0035] Furthermore, the adjustment mechanism 6 includes a limit convex block 24 provided on the lower partition plate 4, a limit hole 22 provided on the upper partition plate 5, and a driving handle 9 provided on the upper partition plate 5. The limit convex block 24 is sleeved in the limit hole 22, and the size of the grid hole 12 is driven and adjusted by the driving handle 9.

[0036] After the lower partition plate 4 and the upper partition plate 5 are assembled, the limit convex block 24 is inserted into the limit hole 22. When adjusting the size of the grid hole 12 on the upper partition plate 5 and the lower partition plate 4 through the adjustment mechanism 6, by driving the handle 9 to drive the upper partition plate 5 to rotate, the size adjustment of the grid hole 12 can be realized. Among them, when the limit convex block 24 is respectively located at the two extremes of the limit hole 22, the grid hole 12 is just in the maximum state and the closed state, so that the adjustment and control of the grid hole 12 are simpler, effectively solving the problem of troublesome adjustment of the size of the grid hole 12, and having low production cost and convenient assembly.

[0037] Among them, a circle of the limit holes 22 is provided around the outer ring of the first mesh hole 21. The limit convex block 24 is connected by inserting into one of the limit holes 22, and the driving handle 9 is an n-shaped structure with an upwardly bent protrusion.

[0038] A circle of limit holes 22 is formed around the outer ring of the first mesh hole 21. When assembling the upper partition plate 5 and the lower partition plate 4, the installation between the two can be more convenient, and the phenomenon of jamming at the middle rotating shaft caused by the misalignment of the limit convex block 24 and the limit hole 22 can be avoided. At the same time, the driving handle 9 is an n-shaped structure with an upwardly bent protrusion, which is more convenient to operate when rotating the upper partition plate 5, can avoid the problem of driving fracture, and the upper partition plate 5 can also be shaken through the driving handle 9 to make the impurities on the upper partition plate 5 fall downward. When there are multiple driving handles 9, it is also convenient to disassemble and assemble the upper partition plate 5, so that when assembling the lower partition plate 4, it is not necessary to install and remove it at the same time as the upper partition plate 5, which is more convenient and labor-saving in operation.

[0039] Furthermore, it is further improved that the first mesh hole 21 and the second mesh hole 23 are both composed of a plurality of arc-shaped holes distributed in concentric circles.

[0040] Both the first mesh hole 21 and the second mesh hole 23 have a number of arc-shaped holes distributed in concentric circles, and when it is necessary to adjust the size of the grid hole 12, the adjustable range is larger.

[0041] Further improved, both the upper partition plate 5 and the lower partition plate 4 are composed of a number of fan-shaped grid plates, and adjacent two grid plates are connected by a pin shaft or fixed by a buckle.

[0042] When the adjusting support plate 11 has a larger diameter, production and transportation are more convenient, avoiding the problem of high production cost and transportation cost due to too large overall area. Moreover, adjacent two grid plates are connected by a pin shaft or fixed by a buckle, which is also more convenient during assembly.

[0043] Further improved, an inwardly protruding drag ring 13 is provided in a ring shape on the inner side of the barrel body 8, and the bottom of the adjusting support plate 11 is supported and positioned by the drag ring 13.

[0044] When disassembling and assembling the adjusting support plate 11, it is simpler and more convenient. Just put the adjusting support plate 11 into the barrel body 8 and place its edge bottom on the drag ring 13 to support and fix it. When the adjusting support plate 11 needs to be repaired, it is also simpler and more convenient, effectively avoiding the problem of troublesome disassembly and repair after the adjusting support plate 11 is installed.

[0045] Even further improved, the water outlet 18 is located in the middle of the barrel body 8, and an upwardly protruding support platform 10 is provided inside the water outlet 18. The adjusting support plate 11 is arranged on the support platform 10, and a metal mesh 19 is provided in a ring shape on the side of the support platform 10.

[0046] The support platform 10 is welded by metal rods, and a metal mesh 19 is wrapped around its periphery. Through the metal mesh 19, large-particle objects can be filtered, the water outlet 18 can be protected to a certain extent, the problem that bullfrogs are discharged from the water outlet 18 when the barrel body 8 is used for breeding after removing the adjusting support plate 11 can be avoided, and at the same time, the middle area of the adjusting support plate 11 can be supported to avoid the problem that the adjusting support plate 11 is deformed due to insufficient support.

[0047] Further improved, a flushing mechanism 2 is provided in a ring shape at the bottom of the barrel body 8, and the attachments adhered to the bottom of the barrel body 8 are subjected to high-pressure flushing by the flushing mechanism 2.

[0048] During the breeding process of bullfrogs, when the bottom of the bucket needs to be rinsed, if the bullfrogs are at the bottom of the bucket, they are easily damaged during rinsing, which increases the number of diseased bullfrogs. After the bullfrogs are supported by adjusting the support plate 11, it is troublesome to clean the bottom of the bucket body 8, and if it is not cleaned thoroughly, the water quality will quickly deteriorate. Therefore, a rinsing mechanism 2 is provided in a circle around the bottom of the body. The attachments adhered to the bottom of the bucket body 8 can be subjected to high-pressure rinsing through the rinsing mechanism 2. This solves the problems of large manual rinsing workload and poor safety, eliminates the problem that bullfrogs are easily damaged due to mutual collision, and makes the meat quality of bullfrogs healthier.

[0049] Further improvement is that the rinsing mechanism 2 includes a shunt pipe 17 arranged in a circle around the bottom of the bucket body 8, a number of high-pressure nozzles 16 arranged on the shunt pipe 17, and at least three water inlet pipes 15 arranged at the bottom of the bucket body 8 and communicated with the shunt pipe 17. The shunt pipe 17 is supported and fixed on the bottom of the bucket body 8 through the water inlet pipes 15, and a manual switch valve 14 is arranged on each of the water inlet pipes 15 outside the bucket body 8.

[0050] When assembling the rinsing mechanism 2, a circular shunt pipe 17 is supported and fixed by a plurality of water inlet pipes 15, which not only reduces the fixing bracket 1, but also increases the number and position orientation of the water inlet pipes 15, enabling the rinsing water pipe to be arbitrarily connected to the outside of any one of the water inlet pipes 15 for water supply, avoiding the problem that the water inlet pipes 15 are inconvenient to connect due to installation position reasons. When rinsing the feces and other garbage adhered to the bottom of the bucket body 8 through the rinsing mechanism 2, only need to connect the rinsing water pipe to one of the water inlet pipes 15, and the water can flow into the shunt pipe 17 through the water inlet pipe 15 and then be ejected outward through the various high-pressure nozzles 16 on the shunt pipe 17. At the same time, when the water pressure needs to be increased, the water supply pressure can also be increased by simultaneously connecting multiple water inlet pipes 15, avoiding the problem that the rinsing pressure is insufficient due to insufficient water pressure. A manual switch valve 14 is provided on the outside of each water inlet pipe 15, and at least 3 water inlet pipes 15 are evenly distributed, which can make its installation more stable and have better concealment, so that no convex structure appears on the outside of the entire bucket body 8. The high-pressure nozzles 16 are installed on the inner side of the shunt pipe 17 and are inclined downward, which can rinse more effectively, and the ejected water can quickly flow to the water outlet 18 for discharge, avoiding the retention of sewage.

[0051] The above embodiments are only the preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantive changes and substitutions made by those skilled in the art based on the present application belong to the scope of protection required by the present application.
