Description

Technical Field

[0001] The invention relates to the technical field of fish breeding, in particular to a throwing device for freshwater fish breeding. Background Art

[0002] In the field of freshwater fish farming, with the rapid development of aquaculture, especially the rise of large-scale, high-density intensive farming, the traditional method of artificially feeding fish feed can no longer meet the needs of modern farming. Against this background, mechanical feeding fish feed equipment came into being. This type of equipment greatly improves feeding efficiency and feed utilization through automated and precise feeding methods;

[0003] In the prior art, the uniformity and accuracy of feed spreading are directly related to the growth efficiency and health status of fish. Although traditional spreading devices can realize mechanized feeding of feed, they are often difficult to meet the specific needs of fish of different species and habits for feed spreading, especially in floating feeding and sinking feeding. The problem is particularly prominent. Floating feeding floats on the water surface, so uniform spreading is required to avoid local excess or shortage of feed. At the same time, excessive aggregation and fighting of fish caused by concentrated feed need to be reduced. Sinking feeding requires more precise control of the spreading position to ensure that fish can forage at an appropriate depth and avoid waste and pollution caused by feed sedimentation at the bottom of the pond. In addition, natural environment such as wind and rain often affect the distribution of feed and the feeding effect of fish, further increasing the complexity of feed management. If the feed is not eaten by fish for a long time after feeding, it will decompose in the water body, causing water pollution and affecting the health of fish. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 8 , a throwing device for freshwater fish farming, comprising:

[0033] A breeding block 1, a breeding pond 2 is provided on the upper surface of the breeding block 1, a staff walkway 3 is provided on the upper surface of the breeding block 1 around the breeding pond 2, a protective railing 4 is also provided on the upper surface of the breeding block 1, the interior of the protective railing 4 is used for breeding freshwater fish, and a throwing mechanism is also provided on the upper surface of the breeding block 1;

[0034] The throwing mechanism includes: a feeder 8, a feed box 12 for filling fish feed inside the feeder 8 is fixedly connected to one side surface of the feeder 8, a discharge port 20 for discharging the feed is provided on the other side of the feeder 8, a movable door that can be opened and closed is provided on the upper surface of the feed box 12, a shielding plate 11 for shielding the feed box 12 is also provided on one side surface of the feeder 8, a signal control box 14 for controlling the feeder 8 is provided on one side surface of the feeder 8, and multiple ventilation holes 10 are provided on one side surface of the feeder 8, and the ventilation holes 10 are provided on the other side surface of the feeder 8. 0 is provided with an interception net at the center, a storage bin 15 is provided inside the feeder 8, a rotatable material turning shovel 16 is provided above the storage bin 15, a spoon mouth is provided at the end of the material turning shovel 16, a driving motor 9 for driving the material turning shovel 16 to rotate is provided on one side surface of the feeder 8, a material discharge slope 17 is also provided inside the feeder 8, a brake motor 18 is also fixedly installed on the side surface of the feeder 8, and a throwing piece 19 of different lengths is provided on the output shaft surface of the brake motor 18, and the throwing piece 19 is located above the discharge port 20;

[0035] When in use, the staff comes to the side of the feeding box 12 through the feeding ladder 13, opens the movable door on the upper surface of the feeding box 12, and pours the pre-prepared fish feed into the feeding box 12. The baffle plate 11 provides protection during the filling process to prevent the feed from being scattered or contaminated. Then, the staff controls the feeder 8 through the signal control box 14. The signal control box 14 is built with a timer and a controller, and can start the feeder 8 according to the set time or instruction. When the set feeding time is reached or the feeding instruction is received, the signal control box 14 sends a start signal to the feeder 8. After the feeder 8 receives the start signal, the drive motor 9 starts working and drives the turning shovel 16 to rotate in the storage bin 15. The end of the turning shovel 16 is designed with a spoon mouth, which can evenly scoop up the feed in the storage bin 15 and throw it downward. During the scooping process, the turning shovel 16 The rotation helps to mix the feed evenly and prevent the feed from agglomerating or clogging in the storage bin 15. The feed thrown up by the turning shovel 16 slides down the discharge slope 17 to the discharge port 20. When the feed reaches the discharge port 20, the brake motor 18 starts to work. The output shaft of the brake motor 18 is equipped with throwing pieces 19 of different lengths. These throwing pieces 19 generate centrifugal force during the rotation process, throwing the feed from the discharge port 20 and throwing it into the breeding pond 2. The different lengths of the throwing pieces 19 enable the feed to be evenly and widely distributed in the breeding pond 2, thereby improving the utilization rate of the feed and the feeding effect of the fish. In addition, a plurality of ventilation holes 10 are provided on the surface of one side of the feeder 8, and an interception net is installed at the center of the ventilation hole 10. The ventilation hole 10 can improve the heat dissipation and ventilation effect inside the feeder 8, and the interception net is used to prevent external debris or insects from entering the feeder 8.

[0036] The above process is the basic process of fish feed spreading at present.

[0037] However, in the actual feeding process, when the feed is thrown into the water by the feeder 8, the feed at the end of the throwing will enter the water faster and stir up the water surface to attract the fish. The position that enters the water first will first cause the fish to gather and compete. When a large number of fish gather in a limited space, the body contact between them will increase, which may cause the fish to be injured and thus affect the appearance of the fish. In addition, when a fixed amount of feed is thrown according to the amount of fish, the gathered fish will compete for limited feed, which may cause some smaller fish to be unable to compete with larger fish for sufficient feed and their growth is restricted, and large fish are also prone to overeating.

[0038] In addition, during the feeding process, floating feeding or sinking feeding will be selected according to the habits of the fish species to feed fish with different habits. Since floating feed floats on the water surface, it has high visibility and fish can find it more easily and approach it for feeding. If floating feed is not scattered evenly, it may cause excess feed in some areas and insufficient feed in other areas. Sinking feed will sink to the bottom of the water after feeding, and fish need to dive to the bottom of the water to feed. Because fish have a certain range of movement when foraging at the bottom of the water, compared with floating feeding, the amount of sinking feed needs to be gathered towards the center. If it is scattered too much, it may increase the difficulty of fish foraging. The two feeds of different properties have different requirements for the spreading of feed, and the selection method is different. It is difficult to ensure that the feed can be accurately sprinkled to the fish according to the characteristics of the feed when raising fish with different habits by using a single spreading method. Moreover, when the feed is floating on the water surface, if there is strong wind or rainfall on the water surface, the feed will float with the changes in the water body, making it more difficult for the fish to find the location of the feed drifting to a hidden position. Moreover, changes in the water environment will produce stress stimulation on the fish, making them nervous and give up feeding. Feed that is not eaten in time will sink to the bottom of the water and decompose after soaking for a period of time, resulting in inconvenience and waste in cleaning, increasing the breeding cost, and polluting the water environment, thereby affecting the health and living environment of the fish.

[0039] Therefore, based on the above problems, we first designed a material transport mechanism, which includes: an electric telescopic rod 34, the electric telescopic rod 34 is located at the inner center of the breeding pond 2, a plurality of sliding rollers 36 are arranged on the bottom surface of the electric telescopic rod 34, a sliding wheel groove 44 matching the sliding rollers 36 is opened at the center of the breeding pond 2, and protective plates 35 are fixedly installed on the two side surfaces of the electric telescopic rod 34, and the protective plates 35 are made of a material with good waterproof performance. A central wedge block 7 is arranged at the end of the output shaft on the upper surface of the electric telescopic rod 34, and a solar panel 28 is arranged inside the central wedge block 7. A waterproof and light-transmitting plate 27 for preventing the solar panel 28 from directly contacting water is also arranged on the upper surface of the central wedge block 7. The output shaft surface of the electric telescopic rod 34 is also sleeved with a plurality of Bottom wedge plate 31, multiple bottom wedge plates 31 are directly connected by connecting arc plates 38, a water leakage port 33 is opened at the center of each bottom wedge plate 31, the width of the water leakage port 33 is smaller than the diameter of the feed, a limiting ring 32 is arranged on the outer surface of the outermost bottom wedge plate 31, a connecting column 39 is fixedly installed on the upper surface of the bottom wedge plate 31, a plurality of attraction lamps 37 are arranged on one side surface of the connecting column 39, the attraction lamps 37 are divided into two groups, the attraction lamps 37 located at the bottom are used to emit yellow light that can attract fish, and the attraction lamps located at the top are used to emit white light that can disperse fish, a top wedge plate 29 is fixedly installed on the upper surface of the connecting column 39, the number of the top wedge plates 29 corresponds to that of the bottom wedge plates 31, and an observation transparent plate 30 is arranged at the center of the top wedge plate 29;

[0040] The feed transport mechanism is used to accurately control and distribute feed in the culture pond 2 to reduce conflicts when fish compete for feed and ensure uniform feed intake. Before feeding, the staff will control the small motor at the bottom of the gathering rod 5 or the bulking rod 6 through the signal control box 14 according to the characteristics of the fed feed, thereby driving the gathering rod 5 or the bulking rod 6 to bend to one side. For example, when feeding floating feed, the bulking rod 6 is driven to bend, and the wedge 23 between the medium-sized intercepting ring 26 above the bulking rod 6 is matched with the top wedge plate 29. When the bulking rod 6 is bent, the top wedge plate 29 is matched with the inside of the wedge 23. At this time, the top surface of the top wedge plate 29 is at the same height as the upper surface of the thin intercepting ring 25, and they are wedged into a whole plate. After that, the electric telescopic rod 34 on the bottom surface is driven by the signal of the signal control box 14, driving the top wedge plate 29 and the bottom wedge plate 31 to rise, and stop rising after the top wedge plate 29 contacts the inner top surface of the limiting groove 21. At this time, the bottom wedge plate 31 replaces the top wedge plate 29 and fits into the inside of the wedge opening 23. Because it is restricted by the limiting ring 32, the bottom wedge plate 31 cannot completely enter the inside of the wedge opening 23, that is, the upper surface of the bottom wedge plate 31 is lower than the upper surface of the thin intercepting ring 25 at this time. At this time, the upper surface of the bottom wedge plate 31 is used as a feed trough. When the feeder 8 throws the feed onto the top of the breeding pond 2, the feed is thrown on the upper surface of the bottom wedge plate 31 and the thin intercepting ring 25 as the feed is fed, and enters the bottom wedge plate 31 as it rolls. The feed trough formed on the upper surface is used for storage. Because the throwing pieces 19 have different lengths and the throwing distances are different each time, a small amount of feed that rolls down from the bottom wedge plate 31 and the upper surface of the thin interception ring 25 during the throwing process cannot produce too much splash to attract a large number of fish because of the small amount. It will only attract a small number of fish and gradually guide the fish to gather on the water surface. The fish can be differentiated by rolling down on both sides and guided to two places for gathering, dispersing the number of gatherings and reducing the degree of competition for subsequent feeding. After the feed is thrown, the electric telescopic rod 34 starts to work. As the electric telescopic rod 34 descends, the bottom wedge plate 31 and the top wedge plate 29 slowly descend to guide the feed to the water surface of the breeding pond 2 In the body, after the bottom wedge plate 31 enters the water, the design of the water leakage port 33 allows water to flow through but prevents the loss of feed. At this time, because the position of the thin interception ring 25 is fixed, after the bottom wedge plate 31 enters the water, the feed gradually contacts the water surface and floats on the water surface. As the bottom wedge plate 31 descends, the top wedge plate 29 above it also descends and re-fits with the wedge opening 23. Because the thickness of the bottom wedge plate 31 and the top wedge plate 29 are both less than the inner wall thickness of the wedge opening 23, when the top wedge plate 29 descends and makes the top surface flush with the upper surface of the thin interception ring 25 in the bent state at this time, a feeding trough is formed on the bottom surface of the top wedge plate 29. At the same time, the attraction lamp 37 starts to work, and the yellow lamp below emits light to attract fish to approach. Because the feed has buoyancy,After being restricted by the inner wall of the thin interception ring 25 on both sides and the bottom surface of the top wedge plate 29 at the top, the fish will not flow out from the inside of the feeding trough. At this time, the fish enter the feeding trough to feed. Because the feeding trough is long and narrow, the fish will gradually disperse to various places in the feeding trough to feed, and will not form a large-scale gathering situation to maintain a good feeding order. After the feeding is completed, the yellow light below is turned off and the white light above is turned on to disperse the fish that are still inside the feeding trough. Then, the electric telescopic rod 34 is restarted and lifted upward to make the bottom wedge plate 31 and the top wedge plate 29 rise. The bottom wedge plate 31 filters out water through the leak 33 opened in the center, and after entering the wedge opening 23, the remaining feed in the feeding trough is supported in the feed trough formed again on the upper surface of the bottom wedge plate 31, and leaves the water surface as the electric telescopic rod 34 is lifted. Subsequent staff can clean up the residual feed collected on the upper surface of the bottom wedge plate 31 to prevent the water body from being polluted.

[0041] At the same time, based on the above problems, we have also designed a material distribution mechanism, which is composed of a guiding component and a shaking component. The guiding component includes: a material gathering rod 5 and a material dispersing rod 6. The material gathering rod 5 and the material dispersing rod 6 are respectively located on the upper surfaces of both sides of the guardrail 4. One side surface of the material gathering rod 5 and the material dispersing rod 6 are provided with a limiting groove 21 for limiting the lifting height of the top wedge plate 29. A plurality of thin interception rings 25 matched with the top wedge plate 29 and the bottom wedge plate 31 are fixedly installed on the upper surface of the material gathering rod 5. A thick interception ring 24 is arranged at the center of the thin interception ring 25. A plurality of wedge openings 23 are provided between the thick interception ring 24 and the thin interception ring 25. The wedge openings 23 are matched with the top wedge plate 29 and the bottom wedge plate 31. A plurality of medium-sized interception rings 26 are fixedly installed on the upper surface of the material dispersing rod 6. A wedge opening 23 identical to that on the top of the material gathering rod 5 is also provided between the plurality of medium-sized interception rings 26.

[0042] The gathering rod 5 and the scattering rod 6 are used to divide the feed according to the feeding characteristics of floating feeding and sinking feeding respectively. When the floating feed with high uniformity needs to be scattered during feeding, the scattering rod 6 is driven to bend, and the wedge 23 between the medium-sized interception ring 26 above the scattering rod 6 is matched with the top wedge plate 29, so as to realize the formation of the feed trough. Because higher uniformity is required, the thickness of the medium-sized interception ring 26 is the same, and the depth of the formed feed trough is also the same. When the sinking feed that needs to be scattered needs to be more gathered, the gathering rod 5 is driven to bend, and the wedge 23 between the thick interception ring 24 and the thin interception ring 25 above the gathering rod 5 is matched with the top wedge plate 29, because the thick interception The thickness of the ring 24 is thicker than that of the medium-sized interception ring 26, while the thickness of the thin interception ring 25 is thinner than that of the medium-sized interception ring 26. Therefore, when the feed is gathered, the feed trough at the center will gather more feed, while the feed trough at the edge will reduce the storage amount of the feed. After the sinking feed enters the water, because it has a stronger sinking characteristic than the floating feed, the sinking feed gradually adheres to the upper surface of the bottom wedge plate 31 as it sinks, so that the fish fed with the sinking feed can feed at a position with a more suitable depth, avoiding the situation where the fish have difficulty in feeding because the feed is not eaten in time and sinks to the bottom. After the feeding is completed, the remaining sinking feed leaves the water surface again as the bottom wedge plate 31 rises, and is subsequently cleaned up by the staff.

[0043] The shaking assembly includes: two rotating seats 22, the two rotating seats 22 are respectively fixedly mounted on the upper surfaces of both sides of the guardrail 4, the bottom surface of the rotating seat 22 is provided with a rolling wheel, the upper surface of the rotating seat 22 is provided with a rotating shaft rod, the interior of the rotating seat 22 is provided with a small motor for driving the rotating shaft rod, and the two sides of the rotating seat 22 are also provided with a telescopic motor 40 and a fixed block 42, the telescopic motor 40 and the fixed block 42 are both fixedly mounted on the upper surface of the guardrail 4, a connecting rod 41 is provided on the output end of the telescopic motor 40, the connecting rod 41 is connected to one side surface of the rotating seat 22, a one side surface of the fixed block 42 is provided with a reset spring 43, and the other end of the reset spring 43 is fixedly connected to one side surface of the rotating seat 22;

[0044] In the process of the feed being gathered through the guiding mechanism, the telescopic motor 40 pushes the rotating seat 22 to perform reciprocating motion through the connecting rod 41 to increase the diffusion range of the feed, and the reset spring 43 provides return power to ensure that the rotating seat 22 can move back and forth stably. The two rotating seats 22 are driven by the telescopic motor 40 to drive the guide assembly to shake slightly through the rotating shaft. This shaking helps to evenly distribute the feed and prevent the feed from piling up in a single position. A plurality of sliding rollers 36 are provided on the bottom surface of the electric telescopic rod 34, and a sliding wheel groove 44 that cooperates with the sliding roller 36 is opened at the center of the breeding pond 2. When the telescopic motor 40 drives the rotating seat 22 to perform reciprocating motion, the material transport mechanism can perform synchronous small-scale activities accordingly to ensure the efficiency of the feed shaking.

[0045] The working principle of the present invention is:

[0046] When in use, the staff comes to the side of the feeding box 12 through the feeding ladder 13, opens the movable door on the upper surface of the feeding box 12, and pours the pre-prepared fish feed into the feeding box 12. Then, the staff controls the feeding machine 8 through the signal control box 14. The signal control box 14 has a built-in timer and controller, which can start the feeding machine 8 according to the set time or instruction. When the set feeding time is reached or the feeding instruction is received, the signal control box 14 sends a start signal to the feeding machine 8. After the feeding machine 8 receives the start signal, the drive motor 9 starts to work, driving the turning shovel 1 6 rotates in the storage bin 15, scoops up the feed in the storage bin 15 and throws it downward, and the feed thrown up by the turning shovel 16 slides along the material discharge slope 17 to the discharge port 20. When the feed reaches the discharge port 20, the brake motor 18 starts to work. The output shaft of the brake motor 18 is equipped with throwing pieces 19 of different lengths. These throwing pieces 19 generate centrifugal force during the rotation process, and throw the feed from the discharge port 20 and throw it into the breeding pond 2. The different lengths of the throwing pieces 19 enable the feed to be evenly and widely distributed in the breeding pond 2, thereby improving the utilization rate of the feed and the feeding effect of the fish;

[0047] Before feeding, the staff needs to generate a signal through the signal control box 14 to control the small motor at the bottom of the gathering rod 5 or the bulking rod 6 according to the characteristics of the feeding feed, so as to drive the gathering rod 5 or the bulking rod 6 to bend to one side. For example, when feeding floating feed, the bulking rod 6 is driven to bend, and the wedge 23 between the medium-sized interception ring 26 above the bulking rod 6 is matched with the top wedge plate 29. When the bulking rod 6 is bent, the top wedge plate 29 is matched with the inside of the wedge 23. When feeding sinking feed that needs to be scattered and needs to be more gathered, the gathering rod 5 is driven to bend, and the wedge 23 between the thick interception ring 24 and the thin interception ring 25 above the gathering rod 5 is matched with the top wedge plate 29.

[0048] After selecting the feeding buoy and driving the bulk material rod 6 to bend, the top surface of the top wedge plate 29 is at the same height as the upper surface of the thin interception ring 25 at this time, and they are wedged into a whole plate. Subsequently, the electric telescopic rod 34 on the bottom surface is driven by the signal of the signal control box 14, driving the top wedge plate 29 and the bottom wedge plate 31 to rise, and the rising stops after the top wedge plate 29 contacts the inner top surface of the limiting groove 21. At this time, the bottom wedge plate 31 replaces the top wedge plate 29 and fits into the inside of the wedge opening 23. Because it is restricted by the limiting ring 32, the bottom wedge plate 31 cannot completely enter the inside of the wedge opening 23, that is, the upper surface of the bottom wedge plate 31 is lower than the upper surface of the thin interception ring 25 at this time. At this time, the upper surface of the bottom wedge plate 31 is used as a feed trough. When the feeder 8 throws the feed onto the top of the breeding pond 2, the feed is thrown on the upper surface of the bottom wedge plate 31 and the thin interception ring 25 as the feed is fed, and it rolls into the feed trough formed by the upper surface of the bottom wedge plate 31 for storage;

[0049] In the process of the feed being gathered through the guide mechanism, the telescopic motor 40 pushes the rotating seat 22 to reciprocate through the connecting rod 41 to increase the diffusion range of the feed, and the reset spring 43 provides return power to ensure that the rotating seat 22 can move back and forth stably. The two rotating seats 22 are driven by the telescopic motor 40 to drive the guide assembly to shake slightly through the rotating shaft. This shaking helps to evenly distribute the feed and prevent the feed from piling up in a single position. The bottom surface of the electric telescopic rod 34 is provided with a plurality of sliding rollers 36. The center of the breeding pond 2 is provided with a sliding wheel groove 44 that matches the sliding roller 36. When the telescopic motor 40 drives the rotating seat 22 to reciprocate, the material transport mechanism can perform synchronous small-range activities to ensure the efficiency of the feed shaking.

[0050] After the feed is thrown, the electric telescopic rod 34 starts to work. As the electric telescopic rod 34 descends, the bottom wedge plate 31 and the top wedge plate 29 slowly descend to guide the feed into the water body of the breeding pond 2. After the bottom wedge plate 31 enters the water, the design of the leak 33 allows water to flow through but prevents the feed from being lost. At this time, because the position of the thin interception ring 25 is fixed, after the bottom wedge plate 31 enters the water, the feed gradually contacts the water surface and floats on the water surface. As the bottom wedge plate 31 descends, the top wedge plate 29 above descends and re-fits with the wedge opening 23, forming a feeding trough on the bottom surface of the top wedge plate 29. At the same time, the attraction lamp 37 starts to work, and the yellow lamp below emits light to attract fish to approach. Because the feed has buoyancy, it is attracted by the inner wall of the thin interception ring 25 on both sides. After the fish enter the feeding trough to feed, the yellow light at the bottom turns off and the white light at the top turns on to drive away the fish that are still in the feeding trough. Subsequently, the electric telescopic rod 34 is restarted and lifted upward to raise the bottom wedge plate 31 and the top wedge plate 29. The bottom wedge plate 31 filters out water through the leaking hole 33 opened at the center, and after entering the wedge opening 23, the remaining feed in the feeding trough is held in the feed trough formed again on the upper surface of the bottom wedge plate 31, and leaves the water surface as the electric telescopic rod 34 is lifted. Subsequent staff can clean the residual feed collected on the upper surface of the bottom wedge plate 31 to prevent the water body from being polluted.
