Description

Technical Field

[0001] This invention belongs to the technical field of loach farming equipment, specifically relating to a loach farming cage and its farming method. Background Technology

[0002] Loach belong to the family Cobitidae. They have a cylindrical body and a laterally compressed and thin caudal peduncle. They are bottom-dwelling fish that inhabit the bottom of various shallow, muddy environments such as rivers, lakes, ditches, paddy fields, and ponds. They are nocturnal and highly adaptable. They can live in environments rich in humus. When the water is low in oxygen, they can jump to the surface to swallow air and breathe normally. Loach has a good taste, tender meat, and very high nutritional value, resulting in a large market demand and a good market price in my country. Currently, loach farming in China generally uses net cages for easy harvesting. However, existing loach farming net cages are usually fixed to the bottom of the water body and cannot be easily adjusted according to the water level. During heavy rains, the water level rises rapidly, easily submerging the net cages and causing the loaches to escape. Furthermore, when harvesting loaches from existing farming net cages, the low water level and wide range of loach movement make harvesting difficult. The net cages need to be manually lifted for easy harvesting, resulting in poor harvesting efficiency. When oxygen is scarce in the water, loaches will jump to the surface to breathe, and existing farming net cages lack escape prevention devices, affecting the farming effect. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings in the prior art by providing a loach farming cage and its farming method, thereby solving the problems that the loach farming cage cannot be adjusted according to the water level, that the farming cage is inconvenient to use when catching loaches, and that the farming cage does not have an escape prevention device.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] In a first aspect, a loach farming cage and its farming method are provided, comprising a cage body; the top of the cage body is provided with an opening, and an escape prevention component is fixedly connected to one side of the opening; at least one adjusting rod is provided on each of the two opposite sides of the cage body, and the cage body is movably positioned at the inner ring of a floating bed by the cooperation of the adjusting rod and the limiting component; the floating bed is slidably positioned on multiple positioning rods.

[0006] Furthermore, the cage body includes a support frame; the support frame is covered with a fish-keeping net around its perimeter and bottom, and hooks are fixedly connected to both ends of the top side of the support frame; an escape prevention device is fixedly connected to the support frame on the opposite side of the hooks.

[0007] Furthermore, the escape prevention component includes a winding shell; the winding shell is fixedly connected to the support frame on the opposite side of the hook and buckle; a winding shaft is rotatably connected inside the cavity of the winding shell, and coil springs are provided at both ends of the winding shaft. The inner ring end of the coil spring is fixedly connected to the rotating shaft of the winding shaft, and the outer ring end of the coil spring is fixedly connected to the cavity of the winding shell; an escape prevention net is wound on the winding shaft, and the pull-out end of the escape prevention net is fixedly connected to a pull rod, which engages with the hook and buckle.

[0008] Furthermore, the adjusting rod includes a rod body; the rod body is fixedly connected to both sides of the top of the support frame, and several locking grooves are equally spaced on the rod body; the locking grooves cooperate with the limiting parts to adjust the water outlet height of the net cage body.

[0009] Furthermore, the floating bed includes a pedal; each of the four corners of the pedal is fixedly connected to a sliding ring, and a positioning rod is slidably connected inside each sliding ring; several limiting components are fixedly connected to the upper part of the pedal.

[0010] Furthermore, multiple floats are fixedly connected to the lower surface of the pedal; the multiple floats are distributed in a rectangular array.

[0011] Furthermore, the limiting component includes a sliding seat; the sliding seat is fixed to the pedal, and the interior of the sliding seat is hollow, with its hollow interior fitting into the rod; a protrusion is integrally formed on one side of the sliding seat, and an adjustment groove is formed on the protrusion, with a locking pin movably disposed in the adjustment groove; a rotating shaft is fixedly connected to the bottom of the locking pin, and the rotating shaft is rotatably connected to the adjustment groove; one end of the locking pin is a pointed tip, which engages with a locking groove on the rod; a spring is fixedly connected to the locking pin, and the other end of the spring is fixedly connected to the protrusion, with a foot block fixedly connected to the locking pin below the spring.

[0012] Furthermore, the positioning rod includes a slide rod; the bottom end of the slide rod is fixedly connected to a connector, and the slide rod is slidably inserted into the sliding ring.

[0013] Secondly, a method for raising loach in a net cage, characterized by comprising the following steps:

[0014] S1. Insert the positioning rod into the bottom of the target water area and fit the sliding ring onto the sliding rod so that the floating bed slides on the positioning rod;

[0015] S2. Place the cage body inside the floating bed, insert the adjusting rod into the limiting part, and adjust the cage body to the appropriate sinking depth.

[0016] S3. Add loach fry and floating weeds into the water inside the cavity of the net cage body, pull the lever and make it lock onto the hook, that is, lay the escape-proof net on the top of the net cage body.

[0017] S4. When catching loach, the escape prevention device is retracted, and the water height of the net cage body is controlled by the limiting device to catch the loach.

[0018] Further, in step S2, adjusting the cage body to a suitable submersion depth includes:

[0019] Step on the foot block to make the locking pin rotate inside the protrusion via the rotating shaft, while the compression spring contracts and compresses, maintaining a rebound force. At this time, the locking pin disengages from the locking groove, allowing the rod to slide down inside the sliding seat. After the position adjustment is completed, release the foot block, and the locking pin engages in the locking groove, keeping the position of the rod fixed, thus completing the adjustment of the submersion depth of the cage body.

[0020] The loach farming cage and farming method provided by this invention have the following beneficial effects:

[0021] The positioning rod of this invention keeps the floating bed in a fixed position in the water, preventing it from floating around. Combined with the floating bed design, during the rainy season when water levels rise rapidly, the net cage body floats on the floating bed as the water level rises, preventing the net cage body from being submerged and causing loaches to escape, thus reducing aquaculture costs. Furthermore, the adjustment rod and limiting components allow control of the net cage body's rising and falling distance on the floating bed, thereby controlling the submersion depth of the net cage body. This facilitates adjustment during loach harvesting. Raising the net cage body reduces the loaches' activity range in the water, improving harvesting convenience. The escape-preventing design prevents loaches from jumping out of the net cage body when oxygen is scarce in the water, and also prevents fish-eating birds from catching the loaches inside the net cage body, improving aquaculture efficiency.

Detailed Implementation

[0028] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0029] Example 1

[0030] refer to Figure 1 The loach farming cage and its farming method in this embodiment include a cage body 3; the top of the cage body 3 is open, and an escape prevention component 6 is fixedly connected to one side of the opening to prevent the loach from escaping; at least one adjusting rod 4 is provided on each of the two opposing sides of the cage body 3, and the cage body 3 is movably positioned in the inner ring of the floating bed 1 by the cooperation of the adjusting rod 4 and the limiting component 5. The floating bed 1 is slidably positioned on multiple positioning rods 2 so that the cage body 3 floats on the floating bed 1 as the water level rises.

[0031] Specifically, such as Figure 2 As shown, the floating bed 1 in this embodiment includes a float 101, a pedal 102, and a sliding ring 103;

[0032] The pedal 102 is provided with multiple limiting parts 5 and multiple floats 101. The multiple floats 101 are arranged in a rectangular array. Sliding rings 103 are fixedly connected to the four corners of the pedal 102. The sliding rings 103 are slidably connected to the slide rods 201. The design of the floating bed 1 in this embodiment meets the usage requirements, making it convenient for staff to step on it and improving the ease of operation during aquaculture.

[0033] like Figure 2 As shown, in this embodiment, the positioning rod 2 includes a slide rod 201 and a connector 202;

[0034] The bottom end of the slide bar 201 is fixedly connected to the connector 202. The slide bar 201 is slidably inserted into the sliding ring 103. Through the design of the positioning rod 2, it is ensured that the floating bed 1 can float in the designated water area and that the floating bed 1 will not drift randomly in windy and wavy weather.

[0035] In this embodiment, the floating bed 1 and the positioning rod 2 work together to allow the floating bed 1 to rise with the water level in the designated water area when the water level rises rapidly during the rainy season. This prevents the net cage body 3 from being submerged due to the rapid rise in water level, thus avoiding the escape of the loaches inside.

[0036] In actual operation, the floating bed 1 is slidably connected to the positioning rod 2. The design of the floating bed 1 allows the net cage body 3 to be installed on top, ensuring that the port of the net cage body 3 has a certain height above the water, ensuring that the loach will not easily escape from the net cage body 3, thus meeting the usage requirements. When catching or feeding the loach, the staff can step on the pedal 102 for a series of operations. Through the design of the positioning rod 2, the floating bed 1 can float within a fixed water area, avoiding the floating bed 1 from floating randomly on the water surface in windy and wavey weather, thus improving the planning effect of the aquaculture area. When the water level rises rapidly during the rainy season, the floating bed 1 will slide on the sliding rod 201 through the sliding ring 103, ensuring that the net cage body 3 will not be submerged and that the position of the floating bed 1 in the water area will not change. The positioning rod 2 is inserted into the bottom silt of the target water area through the plug 202, ensuring that the sliding rod 201 can be used as a support for the sliding ring 103.

[0037] like Figure 3 As shown, in this embodiment, the cage body 3 includes a support frame 301, a fishing net 302, and a hook and fastener 303;

[0038] Fish storage nets 302 are laid around the perimeter and bottom of the support frame 301. Hooks 303 are fixedly connected to both ends of the top side of the support frame 301. Through the design of the support frame 301, the fish storage nets 302 can be laid flat and spread out to ensure the internal space of the net cage body 3 and meet the usage requirements.

[0039] like Figure 3 As shown, in this embodiment, the adjusting rod 4 includes a rod body 401 and a locking groove 402;

[0040] The rod 401 is fixedly connected to both sides of the top of the support frame 301. The rod 401 has equally spaced locking grooves 402. By adjusting the rod 4 and cooperating with the limiting piece 5, the water outlet height of the net cage body 3 can be controlled to ensure the effect of use.

[0041] like Figure 4As shown, in this embodiment, the limiting member 5 includes a sliding seat 501, a protrusion 502, an adjusting groove 503, a locking pin 504, a rotating shaft 505, a spring 506, and a foot block 507.

[0042] The sliding seat 501 is fixedly connected to the pedal 102. The sliding seat 501 is integrally formed with a protrusion 502. The protrusion 502 has an adjustment groove 503. A locking pin 504 is fitted in the adjustment groove 503. The locking pin 504 is fitted and connected to the locking groove 402. A rotating shaft 505 is fixedly connected to the bottom of the locking pin 504. The rotating shaft 505 is rotatably connected in the adjustment groove 503. A spring 506 is fixedly connected to the locking pin 504. The other end of the spring 506 is fixedly connected to the protrusion 502. A foot block 507 is fixedly connected to the locking pin 504 below the spring 506. The design of the limiting part 5 meets the usage requirements and ensures that the adjustment state of the adjusting rod 4 can be controlled to meet the adjustment of the water outlet height of the net cage body 3.

[0043] This embodiment, through the cooperative design of the adjusting rod 4 and the limiting member 5, allows for the adjustment of the adjusting rod 4 on the limiting member 5 when catching loaches inside the net cage body 3. This reduces the submerged area of ​​the net cage body 3, thereby reducing the range of movement of the loaches inside the net cage body 3. Compared with the traditional method of catching loaches by pulling the fish storage net 302 with one hand and holding the landing net with the other hand, the cooperative design of this device improves the convenience of catching loaches.

[0044] Specifically, when it is necessary to catch loaches inside the net cage body 3, by pulling the support frame 301 upward, the adjusting rod 4 will slide within the limiting part 5. Through the cooperation of the locking pin 504 and the locking groove 402, the rod 401 can only slide upward within the sliding seat 501 and cannot slide downward. By adjusting the submersion depth of the net cage body 3, the range of movement of loaches inside the net cage body 3 can be reduced, thus facilitating catching.

[0045] When it is necessary to adjust the sinking of the cage body 3, stepping on the foot block 507 causes the locking pin 504 to rotate within the protrusion 502 via the rotating shaft 505, which in turn compresses the spring 506 and maintains a rebound force. At this time, the locking pin 504 disengages from the locking groove 402, allowing the rod 401 to slide down within the sliding seat 501. After the position adjustment is completed, releasing the foot block 507 allows the locking pin 504 to engage with the locking groove 402, thus fixing the position of the rod 401 and achieving the adjustment effect, thereby realizing the adjustment and control of the water outlet height of the cage body 3.

[0046] like Figure 5 As shown, in this embodiment, the escape prevention component 6 includes a winding shell 601, a winding shaft 602, a coil spring 603, an escape prevention net 604, and a pull rod 605;

[0047] The winding shell 601 is fixedly connected to the support frame 301 on the opposite side of the hook 303. The winding shaft 602 is rotatably connected inside the cavity of the winding shell 601. Both ends of the winding shaft 602 are provided with coil springs 603. The inner ring end of the coil spring 603 is fixedly connected to the rotating shaft of the winding shaft 602, and the outer ring end of the coil spring 603 is fixedly connected to the cavity of the winding shell 601. An escape-proof net 604 is wound on the winding shaft 602. The pull-out end of the escape-proof net 604 is fixedly connected to the pull rod 605. The pull rod 605 is engaged with the hook 303. Through the design of the escape-proof part 6, it can be ensured that the loach will not easily escape from the net cage body 3. It can also prevent fish-eating birds from preying on the loach inside the net cage body 3, thereby improving the aquaculture effect.

[0048] This embodiment, through the design of the escape-proof component 6, can prevent loaches from jumping out of the net cage body 3 when oxygen is insufficient in the water and they jump out of the water to breathe. At the same time, the design of the escape-proof component 6 can also prevent loaches inside the net cage body 3 from being caught by fish-eating birds, thereby improving the aquaculture effect.

[0049] In daily loach farming, the pull rod 605 is pulled and hooked onto the hook 303, allowing the escape-proof net 604 to be laid above the net cage body 3. Pulling the pull rod 605 causes the coil spring 603 to coil and maintain its rebound force. After the escape-proof net 604 is laid, it can prevent loaches from escaping the net cage body 3 when jumping, and it can also prevent fish-eating birds from catching and eating the loaches inside the net cage body 3, thus improving the farming effect. When it is necessary to feed or catch loaches, the pull rod 605 is removed from the hook 303, and the coil spring 603 will rebound, driving the winding shaft 602 to rotate and thus the escape-proof net 604 is wound up by the winding shaft 602 in the cavity of the winding shell 601, improving the ease of winding up the escape-proof net 604. The design of this device meets the usage requirements and improves the use effect of the loach farming net cage.

[0050] Example 2

[0051] refer to Figures 1-5 This embodiment of a loach farming cage and its farming method includes the following steps:

[0052] Step S1: First, insert the positioning rod 2 into the bottom of the target water area, and then fit the sliding ring 103 onto the sliding rod 201 so that the float 1 and the positioning rod 2 are connected.

[0053] Step S2: Next, place the net cage body 3 inside the floating bed 1, so that the adjusting rod 4 is inserted into the limiting member 5, and adjust the net cage body 3 to a suitable sinking depth.

[0054] Step S3: Next, add the loach fry and floating weeds into the water inside the cavity of the net cage body 3. At this time, pull the lever 605 and make it lock onto the hook 303. At this time, the escape-proof net 604 is laid on the top of the net cage body 3.

[0055] Step S4: Finally, during loach harvesting, the escape prevention component 6 is retracted, and the water outlet height of the net cage body 3 is controlled by the limiting component 5 to achieve loach harvesting.

[0056] Although specific embodiments of the invention have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent.
