Description

Technical Field

[0001] The present application relates to the technical field of aquatic breeding and feeding, and in particular to a device for aquaculture seedling breeding and feeding. Background Art

[0002] In the field of aquatic breeding, water quality management is one of the key factors to ensure the healthy growth of fry. The water in the breeding box often deteriorates due to the excrement of fry, uneaten feed residues and the growth of microorganisms, resulting in a decline in water quality, a decrease in dissolved oxygen, and the accumulation of harmful substances such as ammonia nitrogen and nitrite. These unfavorable conditions will seriously affect the growth rate and survival rate of fry, and even cause disease and death. Therefore, regular water changes in the breeding box and treatment of feed residues are necessary operations to maintain good water quality and promote the healthy development of fry.

[0003] However, the existing breeding boxes have certain limitations in the water exchange process. For example, when draining water through a suction pipe or a drain outlet of the breeding box, the fry are easily sucked into the suction pipe or discharged from the drain outlet together. Excessive water flow can easily cause damage and death to the fry. In addition, when regularly cleaning feed residues in the water, a small-diameter suction pipe is generally used to extract the feed residues inside the breeding box. This method is easy to extract smaller fry together when cleaning the feed residues, which has certain shortcomings.

[0004] Therefore, the present invention proposes an aquaculture seedling breeding and raising equipment. Summary of the invention

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0040] like Figure 1-Figure 14 As shown, an aquaculture seedling breeding and rearing device proposed in one embodiment of the present application includes:

[0041] A breeding box 1, which is transparent as a whole and has an opening at the top, a partition 2 is installed near the bottom of the breeding box 1, and a drainage groove 3 is penetrated and opened on one side of the breeding box 1 near the partition 2;

[0042] The chip removal mechanism 5, the breeding box 1 has a structure 501 flush with the top of the partition 2, the structure 501 is located on one side of the partition 2 and has openings at both ends, one of the openings of the structure 501 is vertically upward and flush with the partition 2, and the other opening is located outside the breeding box 1 and is blocked by a plug 502, and the plug 502 can be installed on the breeding box 1 by bolts;

[0043] The drainage mechanism 4 includes a drainage cover 401 rotatably installed in the breeding box 1. The drainage cover 401 has an outer arc surface and a plane end. The plane end of the drainage cover 401 is an opening, and the outer arc surface of the drainage cover 401 is a blocking surface, which is used to block the drainage groove 3. A driving component 8 for driving the drainage cover 401 to rotate is installed on the outside of the breeding box 1. Specifically, one side of the structural part 501 is arc-shaped, and the outer arc surface of the drainage cover 401 fits the arc of the structural part 501. The fry on the breeding box 1 is located above the partition 2 and moves. In normal use, the opening of the drainage cover 401 faces the outside of the breeding box 1, and the outer arc surface of the drainage cover 401 blocks the drainage groove 3. At this time, the plug 502 blocks the open end of the structural part 501 to prevent the water in the breeding box 1 from flowing to the outside.

[0044] The protective mechanism 6 includes a baffle 601 rotatably mounted on the breeding box 1, a cavity is formed between the baffle 601 and the breeding box 1, the structural part 501 and the drainage cover 401 are both located in the cavity, a plurality of water grooves 602 are provided on the baffle 601, and a shielding member 603 for shielding the water grooves 602 is installed on the baffle 601. When the water in the breeding box 1 needs to be replaced, the drainage cover 401 can be driven to rotate continuously by the driving component 8. When the opening end of the drainage cover 401 rotates into the breeding box 1, the water in the breeding box 1 will enter the drainage cover 401, and as the drainage cover 401 continues to When the drain cover 401 is rotated, the open end of the drain cover 401 will rotate to the outside of the breeding box 1, so that the water in the drain cover 401 will be discharged under the action of gravity. When the drain cover 401 is draining, the outer arc surface of the drain cover 401 just blocks the drain groove 3. By rotating the drain cover 401 to drain, the water flow can be gently promoted to reduce the impact on the fry, and at the same time it helps to evenly distribute the water flow to avoid excessive local water flow. It should be noted that when the drain cover 401 is rotated to drain, the water groove 602 on the baffle 601 is in an unblocked state, thereby ensuring that there is always water in the cavity between the baffle 601 and the breeding box 1;

[0045] The transport mechanism 7 is installed in the breeding box 1, and is used to transport impurities on the top of the partition 2 to the direction of the structural part 501. When it is necessary to clean the feed residue in the water, the feed residue will slowly sink to the bottom of the water and be located on the top of the partition 2. At this time, the feed residue on the partition 2 can be moved toward the direction of the structural part 501 through the transport mechanism 7. When the transport mechanism 7 is used, the baffle 601 is in an open state, so that the feed residue in the water can pass through the baffle 601 and enter the interior of the structural part 501. When the feed residue enters the cavity formed by the baffle 601 and the breeding box 1, the baffle 601 is rotated so that the baffle 601 is in a closed state, and then the water trough 602 is blocked by the structural part 501, and finally When the plug is removed from the structural part 501, the water in the cavity formed by the baffle 601 and the breeding box 1 will flow from the structural part 501 to the outside. As the water flows, the feed residues in the water will also be discharged. Therefore, when the feed residues are discharged, due to the shielding of the baffle 601, no large water flow fluctuations will be generated in the breeding box 1, which greatly reduces the impact of the water flow on the fry. Compared with the prior art, the baffle 601 cooperates with the rotating cover and the transportation mechanism 7 to reduce the water flow fluctuations in the breeding box 1 when changing water and regularly cleaning the feed residues, prevent the fry from being damaged due to excessive water flow, and effectively prevent the fry from being accidentally pumped out when pumping water and cleaning the feed residues in the breeding box 1.

[0046] like Figure 4 As shown, in some embodiments, the transport mechanism 7 includes two transmission rollers 701 rotatably mounted on the breeding box 1, a transmission wheel 702 is mounted on the outer side of the transmission roller 701, the two transmission wheels 702 are located below the partition 2 and a transmission belt 703 is installed therebetween, the transmission belt 703 is made of rubber, the transmission belt 703 is horizontally arranged and the bottom plane of the upper horizontal end is close to the top of the partition 2, the transmission belt 703 fits tightly to the breeding box 1, and a motor for driving one of the transmission rollers 701 to rotate is installed on the outer side of the breeding box 1. Specifically, the transmission belt 703 is made of rubber and fits tightly to the transmission belt 703, which can effectively prevent water from flowing out of the gap between the breeding box 1 and the transmission belt 703, and has a good sealing effect. In addition, sealing strips are installed on the structure 501 and the transmission belt 703 to improve the sealing effect. The lower plane of the upper section of the transmission belt 703 contacts the top of the partition 2 to support the transmission belt 703. That is to say, the impurities on the breeding box 1 will sink on the transmission belt 703 in the water. When the external motor starts and drives the transmission wheel 702 to rotate, the rotation of the transmission wheel 702 will drive the transmission belt 703 to move. As the transmission belt 703 moves, the impurities on the transmission belt 703 will move toward the direction of the structure 501 until they enter the structure 501. Because the transmission belt 703 is located above the partition 2, the impurities and feed submerged in the breeding box 1 will fall onto the transmission belt 703, thereby improving the cleaning effect.

[0047] like Figure 4 and Fig.13 As shown, in some embodiments, a groove 704 is provided on the outer surface of the transmission belt 703, and a raised flexible rubber sheet 705 is constructed on one side of the groove 704. The flexible rubber sheet 705 blocks the opening of the groove 704, and a convex rubber strip 706 is constructed at the free end of the flexible rubber sheet 705. Specifically, when the transmission belt 703 continues to move, the flexible rubber sheet 705 will be squeezed into the groove 704 when it contacts the inner wall of the breeding box 1 to completely fill the groove 704, and when the flexible rubber sheet 705 does not contact the inner wall of the breeding box 1, the flexible rubber sheet 705 will be slightly raised due to its own elasticity. At this time, the flexible rubber sheet 705 blocks the open end of the groove 704. When the flexible rubber sheet 705 is resisted by the inner wall of the breeding box 1, the groove 704 is filled. The convex rubber strip 706 is slightly higher than the transmission belt 703, but because the convex rubber strip 706 has a certain elastic deformation, it will not affect the movement of the transmission belt 703. When the flexible rubber sheet 705 is above the moving partition 2, because the flexible rubber sheet 705 has a certain degree of warping, it can better transport the impurities on the transmission belt 703 to the direction of the structural part 501, further improving the speed of transporting impurities inside the breeding box 1.

[0048] like Figure 1 and Fig.12 As shown, in some embodiments, a water inlet pipe 9 is installed on the breeding box 1, one end of the water inlet pipe 9 is located in the breeding box 1, and the other end is located outside for connecting to an external water source. The driving component 8 acts on the water inlet pipe 9. When water flows inside the water inlet pipe 9, the driving component 8 drives the drainage cover 401 to rotate. That is to say, one end of the water inlet pipe 9 can be connected to an external water pipe, and the other end of the water pipe can be connected to a faucet or a water pump. When the water in the water inlet pipe 9 is in a flowing state and flows into the breeding box 1, the driving component 8 can drive the drainage cover 401 to rotate, thereby draining the water in the breeding box 1 without providing additional driving force to the drainage cover 401. The water inlet pipe 9 simultaneously fills the breeding box 1 with clean water. The water in the breeding box 1 is diluted for a period of time to complete the water change. It should be noted here that in the aquatic seedling breeding box 1, the water body is usually not completely replaced when changing water, but a dilution method is adopted. This is mainly because the fry are sensitive to changes in water quality, and large changes in water quality may cause stress and damage. Partial water changes help maintain stable water quality, protect the balance of beneficial microorganisms, and reduce the risk of disease.

[0049] like Figure 3 and Fig.12As shown, in some embodiments, both ends of the drainage cover 401 are configured with convex rods, which are rotatably mounted on the breeding box 1, and the driving assembly 8 includes a small gear 801 rotatably mounted on the breeding box 1, and the small gear 801 is connected to the convex rod. A mounting cavity 802 is configured on the water inlet pipe 9, and two mutually meshing water gears 803 are rotatably mounted in the mounting cavity 802 through the rod body, one of which is located outside and is equipped with a large gear 804, and the large gear 804 is meshed with the small gear 801, and the water gear 803 is attached to the inside of the mounting cavity 802. The water inlet pipe 9 flows through between the two water gears 803. When the water flows into the water inlet pipe 9, as the water flows in the water inlet pipe 9, the water flow will drive the two water gears 803 to rotate, and the rotation of one of the water gears 803 will The large gear 804 is driven to rotate. Since the large gear 804 is meshed with the small gear 801, the small gear 801 will also rotate at this time. As the small gear 801 rotates, the convex rod will be driven to rotate, thereby realizing the rotation of the drainage cover 401. It should be noted that the design of the large gear 804 and the small gear 801 is to prevent the drainage cover 401 from rotating too slowly and causing the water in the breeding box 1 to rise too quickly. Preferably, if it is necessary to further ensure the water quality inside the breeding box 1 and reduce the frequency of water changes, the models of the large gear 804 and the small gear 801 can be replaced, and the diameter of the water inlet pipe 9 can be reduced. The water in the water inlet pipe 9 continuously transports water to the breeding box 1, and the drainage cover 401 also rotates to drain water outward, thereby realizing water circulation in the breeding box 1 and maintaining the water level at an appropriate height.

[0050] like Figure 4 and Fig.10As shown, in some embodiments, the thick wall portion of the baffle 601 is hollow, the water channel 602 is opened in the hollow portion of the baffle 601, the shielding member 603 includes a moving bar 6031 slidably installed in the hollow portion of the baffle 601, a plurality of blocking plates 6032 are linearly arrayed on the moving bar 6031, which are used to shield the water channel 602, one end of the moving bar 6031 passes through the baffle 601 and is located outside the baffle 601, a positioning protrusion 604 is vertically slidably installed on the end of the moving bar 6031 located outside the baffle 601, one end of the positioning protrusion 604 is an outer arc surface, two concave holes 605 are opened on the baffle 601 for inserting one end of the outer arc surface of the positioning protrusion 604, and a notch 60 is opened on one side of the positioning protrusion 604 located outside the baffle 601 6. A spring is installed between the positioning protrusion 604 and the baffle 601. The design of the concave hole 605 is to facilitate the staff to move multiple blocking plates 6032 from the outside of the breeding box 1. The staff can use a long rod to insert into the concave hole 605, and then move the long rod to drive the positioning protrusion 604 to move. As the positioning protrusion 604 moves, the moving bar 6031 connected to it will move, thereby driving the movement of multiple blocking plates 6032. Because one end of the positioning protrusion 604 is an outer arc surface, and the outer arc surface is inserted into the insertion end of the concave hole 605, the positioning protrusion 604 will not only not affect the movement of the moving bar 6031, but also can play a certain degree of positioning role, thereby preventing the blocking plate 6032 from accidentally shifting after moving.

[0051] like Figure 4 and Fig.11 As shown, in some embodiments, an n-type plate 10 is vertically slidably installed on the outside of the breeding box 1, and a hinged rod 11 is installed between one end of the n-type plate 10 and the baffle 601. The design of the n-type plate 10 is convenient for the staff to control the rotation of the baffle 601 outside the breeding box 1, which is more convenient to use. It is not easy to get the staff's arms wet when rotating the baffle 601. During specific operation, it is only necessary to vertically move the n-type plate 10. When the n-type plate 10 moves, it will drive the movement of the hinged rod 11. Because one end of the hinged rod 11 is hinged on the baffle 601, when the n-type plate 10 moves, it will indirectly drive the baffle 601 to rotate through the hinged rod 11, thereby realizing the rotation of the baffle 601.

[0052] like Figure 2 and Fig. 9As shown, in some embodiments, a separation plate 12 is further included, and a vertically downwardly facing card plate 13 is symmetrically constructed on the separation plate 12. A card seam 14 is formed between the card plate 13 and the separation plate 12, and the card plate 13 is tightly inserted into the open end of the breeding box 1 through the card seam 14. A plurality of sieve holes 15 are opened on the separation plate 12, and an adjustment part 16 for adjusting the aperture of the sieve holes 15 is installed on the separation plate 12. When aquatic seedlings are raised, in order to solve the space problem, the separation plate 12 is generally installed in the breeding box 1 to separate the fry of different types or sizes. The function of the separation plate 12 The purpose is to prevent the phenomenon of big fish eating small fish, and different types of fish fighting each other. When using the separation plate 12, if you need to clean the feed residue or impurities inside the breeding box 1, you can gently lift the corresponding separation plate 12 when the conveyor belt 703 is conveyed so that the impurities stick to one side of the separation plate 12, so as to continue to convey the impurities in the direction of the structural part 501. It should be noted that the convex rubber strip 706 and the flexible rubber plate 705 do not affect the use of the separation plate 12. The convex rubber strip 706 and the flexible rubber plate 705 are both made of rubber and have good elastic deformation ability. The convex rubber strip 706 can be hollow and made of rubber material to further prevent the convex rubber strip 706 from affecting the separation plate 12, and the inner hole of the screening hole 15 can be adjusted through the adjustment part 16, thereby increasing the use range of the separation plate 12.

[0053] like Figure 2 , Figure 8 and Fig. 9 As shown, in some embodiments, the separation plate 12 is hollow inside and has an opening at the top, the adjustment portion 16 includes an elastic rubber ring 17, the two ends of the elastic rubber ring 17 are respectively connected to the edges of the two coaxial screening holes 15 that are away from each other, and a plurality of connecting arc plates 18 are slidably installed in a circular array around the axis of the elastic rubber ring 17 in the separation plate 12, and the inner arc surface of the connecting arc plate 18 is connected to the elastic rubber ring 17, and an adjustment component 19 for driving the movement of the plurality of connecting arc plates 18 is installed on the separation plate 12, that is, the corresponding connecting arc plates 18 distributed in the circular array are moved away from each other by the adjustment component 19, thereby pulling the elastic rubber ring 17 to change The pore size inside the elastic rubber ring 17 is adjusted, and the pore size of the screening hole 15 is indirectly changed. Specifically, the inner cross-section of the elastic rubber ring 17 is arc-shaped. Under normal conditions, the middle part of the inner side of the elastic rubber ring 17 is in a fitted state. When the multiple connecting arc plates 18 are driven to move by the adjustment component 19, the elastic rubber ring 17 will be pulled. The elastic rubber ring 17 will change the internal pore size due to elastic deformation. The pore size of the screening hole 15 is indirectly changed by the elastic rubber ring 17. Because the elastic rubber ring 17 has a smooth transition inside, the fry are not easily stuck in the elastic rubber ring 17 when swimming in the breeding box 1, which further improves the survival rate of the fry in the breeding box 1.

[0054] like Figure 8 and Fig. 9 As shown, in some embodiments, the adjustment assembly 19 includes a plurality of annular plates 1901 rotatably mounted inside the separation plate 12, the plurality of annular plates 1901 are coaxial with the plurality of sieve holes 15, and a plurality of arc-shaped toggle plates 1902 are configured on the outer side of the annular plate 1901, one end of the arc-shaped toggle plate 1902 is an inclined surface, and a convex plate 1903 is configured on the outer arc surface of the connecting arc plate 18, and a wedge block 1904 is configured on one side of the convex plate 1903, and the inclined surfaces of the plurality of arc-shaped toggle plates 1902 are used to contact the inclined surfaces of the wedge blocks 1904. , a connecting plate 1905 is inserted into the open end of the separation plate 12 for vertical sliding, and a plurality of racks 1906 are vertically installed on the connecting plate 1905. A transmission gear 1907 meshing with the racks 1906 is installed on the outer side of the annular plate 1901. A protrusion 1908 is constructed on the connecting plate 1905, and an adjusting screw 1909 is vertically rotatably installed on the separation plate 12. The protrusion 1908 is threadedly sleeved on the adjusting screw 1909. It should be noted that the water level in the breeding box 1 cannot be higher than the top surface of the separation plate 12. When the elasticity needs to be adjusted When the inner diameter of the rubber ring 17 is adjusted, it is only necessary to rotate the adjusting screw 1909. When the adjusting screw 1909 rotates, the protrusion 1908 is driven to move. When the protrusion 1908 moves, the connecting plate 1905 is driven to move. As the connecting plate 1905 moves, the multiple racks 1906 are moved. The multiple racks 1906 are respectively engaged with the transmission gears 1907 in the same direction. Therefore, the multiple transmission gears 1907 rotate at the same time. Because the transmission gears 1907 are rotatably mounted on the annular plate 1901, The annular plate 1901 will also rotate, and the rotation of the annular plate 1901 will drive the multiple arc-shaped toggle plates 1902 to move. At this time, the inclined surface of the arc-shaped toggle plate 1902 will contact the inclined surface of the wedge block 1904. As the arc-shaped toggle plate 1902 continues to move, the inclined surface of the arc-shaped toggle plate 1902 will force the wedge block 1904 to move, thereby realizing that the multiple annular plates 1901 move away from each other, thereby being able to change the apertures of the multiple elastic rubber rings 17 on the separation plate 12 at the same time, and being more convenient to adjust.
