Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, specifically to a surface feeding device for fishery feed. Background Technology

[0002] In the daily process of fish farming, fishermen need to feed the fishponds every day to ensure a food supply for the fish. However, the current method of feeding is usually tossing the feed manually while standing on bamboo rafts. This method is not only physically demanding and inefficient, but also poses a high safety risk, as fishermen may fall into the fishpond due to instability while standing on the bamboo rafts. Automated feeding devices can significantly improve work efficiency, reduce physical exertion, and enhance the safety of fishermen, avoiding potential dangers.

[0003] For example, Chinese Patent Publication No. CN114097695B relates to a feeding device, and more particularly to a quantitative feed feeding device for aquaculture. The technical problem of this invention is to provide a quantitative feed feeding device for aquaculture that has a wide feeding range and automatically floats on the water surface. This invention provides such a quantitative feed feeding device for aquaculture, including a first float and a protective chamber, the protective chamber being installed on top of the first float; a protective frame, the protective frame being installed in the middle of one side of the protective chamber; a paddle, the paddle being installed inside the protective frame; a feeding mechanism, the feeding mechanism being installed on the upper side of one side of the protective chamber; a discharging mechanism, the discharging mechanism being installed on the upper middle side of the protective chamber; and a stirring mechanism, the stirring mechanism being installed on the discharging mechanism. This invention, under the action of the paddle, can rotate a second movable plate, thereby automatically discharging the feed, thus saving human labor and improving work efficiency.

[0004] Although this type of feeding equipment successfully delivers feed, some freshwater and ornamental fish tend to eat the feed that floats on the surface. Uneaten feed not only sinks to the bottom over time, causing waste, but also leads to environmental pollution. Furthermore, most of the uneaten feed can become a breeding ground for bacteria and parasites, especially in warm environments where residual organic matter decomposes rapidly, breeding a large number of microorganisms. This not only affects water quality but also increases the risk of fish diseases and adds to the burden of aquaculture management. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 8The present invention provides a technical solution: a fishery feed water surface delivery device, including a bottom plate 1, characterized in that: a floating plate 4 is fixedly installed at the bottom of the bottom plate 1, a rotatable drive wheel 5 is installed on the outer wall of the floating plate 4, a shell 2 is fixedly installed at the top of the bottom plate 1, and a feed cylinder 9 is fixedly installed at the top of the bottom plate 1 through a first mounting seat 8;

[0035] It also includes a feeding assembly installed on top of the base plate 1, which can feed the feed in the feed cylinder 9 onto the water surface;

[0036] It also includes a recycling component that can recover and process feed residue on the water surface and re-feed it through the feeding component.

[0037] When using this device, first put the fish feed into the feed cylinder 9, then place the entire device on the water surface of the feeding area. Under the buoyancy of the float plate 4, the entire device will float on the water surface. The motor drives the drive wheel 5 to rotate and travel along a predetermined route. During the travel, the feed inside the feed cylinder 9 is put onto the water surface through the feeding component. By controlling the travel speed of the device, it can be ensured that the feed is evenly distributed on the water surface, avoiding local overfeeding or underfeeding. Furthermore, a camera and sensor can be installed on the outer wall of the outer shell 2 for monitoring, so that the fish farmer can understand the feeding situation in real time.

[0038] After the device completes the planned route, it returns to the initial position and travels along the predetermined route again. During the second journey, the recovery component will collect the feed that has not been eaten by the fish and put it back on the water surface through the feeding component during the next feeding, thus completing the recovery and refeeding of the residual feed.

[0039] By combining the feeding and recycling components, feed can be automatically delivered to the water surface, reducing manual labor, saving time and energy costs, and reducing the risks for fishermen operating on the water, thus improving safety. During the delivery process, uneaten feed can be recovered, reducing the accumulation of organic matter in the water, preventing water quality deterioration, protecting the aquatic environment, and providing a better living environment for fish. Furthermore, the recovery and reuse of uneaten feed can reduce feeding costs and improve economic efficiency.

[0040] Furthermore, the feeding assembly includes a feeding body 20 fixedly installed on the top of the base plate 1. The feeding body 20 has an internal launching channel 23 and an inlet 19 connected to the launching channel 23 on the top of the feeding body 20. The outer wall of the material cylinder 9 has a discharge port 14, and the discharge port 14 and the inlet 19 are connected by a moving pipe 15.

[0041] The feeding assembly also includes an air blowing assembly that can blow the feed that falls into the launch channel 23 to the water surface.

[0042] See Figure 5 as well as Figure 6 When it is necessary to feed the fish in the water, the feed in the feed cylinder 9 will fall into the launch channel 23 through the feed outlet 14, the moving pipe 15 and the feed inlet 19 in sequence. Then, the feed that has fallen into the launch channel 23 will be blown to the water surface by the air blowing component, so as to achieve the purpose of putting the feed in the feed cylinder 9 onto the water surface. Through automated feeding, the breeding efficiency can be improved, allowing the breeder to have more time to carry out other management work.

[0043] It is worth mentioning that the feeding direction is preferably the opposite of the driving direction, so that the feed will be more evenly distributed on the water surface. This is because the feed will be dispersed with the water flow and the movement of the device after it is thrown out, and direct contact with the feeding area is avoided, reducing direct interference to the fish.

[0044] Furthermore, the air blowing assembly includes two fourth mounting seats 37 fixedly installed on the top of the base plate 1. The two fourth mounting seats 37 are respectively installed on the front and rear sides of the material cylinder 9. Rotating rods 10 are rotatably installed on the opposite surfaces of the two fourth mounting seats 37. The two rotating rods 10 penetrate the outer wall of the material cylinder 9 and are rotatably connected to the penetration point. The axis of the rotating rod 10 is eccentrically set with the axis of the material cylinder 9. A piston body 11 is fixedly installed between the two rotating rods 10. A piston plate 12 is slidably installed on the inner wall of the piston body 11. Drive plates 13 are fixedly installed on both outer walls of the piston plate 12. The two drive plates 13 penetrate the outer wall of the piston body 11 and can contact and abut against the inner wall of the material cylinder 9.

[0045] The blowing assembly also includes an air hole with a one-way valve installed on the outer wall of the piston body 11. Both rotating rods 10 have an air passage 21 with a one-way valve installed inside. Both air passages 21 are connected to the inside of the piston body 11. Both rotating rods 10 have a connecting pipe 22 rotatably installed at opposite ends. The connecting pipe 22 connects the air passage 21 to the firing channel 23.

[0046] See Figure 4 as well as Figure 5A motor is fixedly installed on the outer wall of the first mounting base 8. The drive shaft of the motor is connected to a sprocket. A sprocket is fixedly installed on the outer wall of one of the rotating rods 10. The two sprockets are connected by a chain. When the device is working, the drive motor, through the cooperation of the sprocket and the chain, will drive one rotating rod 10 to rotate along the axis, thereby driving the piston body 11 and the other rotating rod 10 to rotate. During the rotation of the piston body 11, the two drive plates 13 will alternately contact the inner wall of the feed cylinder 9, so that the piston plate 12 will reciprocate within the piston body 11. During this process, air in the feed cylinder 9 can be drawn into the piston body 11 and transported through the ventilation channel 21 to the connecting pipe 22, and then transported through the connecting pipe 22 to the launching channel 23, thereby blowing the feed that falls into the launching channel 23 onto the water surface to complete the feed delivery.

[0047] During the above process, the airflow, through the cooperation of piston body 11, piston plate 12 and drive plate 13, delivers the feed that falls into the delivery channel 23. The airflow delivery is gentler, which can reduce the disturbance to the fish and avoid frightening the fish. It can also help to spread the feed evenly, ensuring that each fish has a chance to get food and reducing competition and unfairness. In addition, as the drive plate 13 rotates with piston body 11, it will stir the feed inside the feed cylinder 9, reduce the sticking of feed in the humid environment, ensure smooth delivery, and make the additives and nutrients in the feed evenly distributed.

[0048] It is worth mentioning that when the drive plate 13 passes through the opening of the feed inlet 14 each time, it can not only prevent the feed from accumulating at the opening of the feed inlet 14 and causing blockage, but also, through the stirring and passing action, the feed can fall more evenly into the launching channel 23, so as to ensure that the amount of feed is consistent each time.

[0049] Furthermore, the recycling assembly includes a collection chamber 6 fixedly installed at the bottom of the base plate 1, a filter plate 7 installed at the inlet of the collection chamber 6, a recycling channel 24 connected to the inside of the collection chamber 6 fixedly installed on the outer wall of the collection chamber 6, and several water outlets 25 opened on the outer wall of the collection chamber 6 away from the filter plate 7.

[0050] The recycling assembly also includes a dehydration assembly that dries the feed recycled within the recycling channel 24.

[0051] Combination Figure 1 , Figure 7 as well as Figure 8When this device is working, half of the collection chamber 6 will be submerged in water. When it travels along the predetermined route for the second time, the filter plate 7 will filter out garbage or foreign objects in the water and collect water and residual feed into the collection chamber 6. As the device moves forward, water will flow out from the outlet 25 and cause the residual feed to flow into the recycling channel 24. The feed in the recycling channel 24 will be dehydrated and dried by the dehydration component to facilitate subsequent secondary feeding. After drying, the feed will not clump and will be easier to distribute evenly, thus improving the feeding rate of fish.

[0052] It is worth mentioning that the inner walls on both sides of the collection chamber 6 gradually move towards the middle to facilitate the stable entry of residual feed into the recycling channel 24.

[0053] Furthermore, the dehydration assembly includes a drying barrel 30 fixedly mounted on the top of the base plate 1 via a third mounting base 29. Rotating blades 31 are installed on the inner wall of the drying barrel 30. A diversion pipe 32 connected to the connecting pipe 22 is fixedly connected to the outer wall of the drying barrel 30, and the diversion pipe 32 is connected to the interior of the drying barrel 30. A reuse pipe 33 connected to the feed inlet 19 is fixedly installed on the outer wall of the drying barrel 30, and the air outlet of the diversion pipe 32 corresponds to the inlet of the reuse pipe 33.

[0054] The dehydration assembly also includes a return pipe 26 integrally formed with the recovery channel 24, and the return pipe 26 is connected to the inside of the drying barrel 30. A rotating conveying auger 27 is installed on the inner wall of the return pipe 26, and several water outlet holes 28 are opened on the inner wall of the return pipe 26, and the water outlet holes 28 are located above the water surface.

[0055] See Figure 5 as well as Figure 7 When traveling along the predetermined route for the second time, the water will carry the remaining feed from the recycling channel 24 into the return pipe 26, and the conveyor auger 27 will be driven by the motor to rotate, thereby conveying the feed that has entered the return pipe 26 into the drying barrel 30. During this process, the remaining water will flow out from the return pipe 26 through the water outlet 28.

[0056] There is a certain gap between one end of the drying barrel 30 and the rotating blade 31, and the connection between the inner wall of the drying barrel 30 and the return pipe 26 is sloped. This allows the feed entering the drying barrel 30 through the return pipe 26 to slide down below the rotating blade 31. As the rotating blade 31 rotates, it drives the feed inside the drying barrel 30 to move within the barrel. During this process, some of the air entering the feed inlet 19 enters the drying barrel 30 through the diversion pipe 32, drying the feed inside. Once the feed is completely dry, it is lifted by the rotation of the rotating blade 31 and blown into the reuse pipe 33 by the air blown out through the diversion pipe 32. From there, it falls back through the feed inlet 19 into the launch channel 23 and is blown back to the water surface. Through the combination of the above structures, the purpose of secondary recycling of residual feed is achieved, reducing the accumulation of organic matter in the water, preventing water quality deterioration, reducing feeding costs, and improving economic efficiency.

[0057] It is worth mentioning that the blades of the conveyor auger 27 have several holes. During the process of conveying feed by the conveyor auger 27, some of the residual moisture will flow out from the water outlet 28, and some will flow back to the bottom of the return pipe 26 through the holes on the blades, preventing the conveyor auger 27 from conveying the residual moisture into the drying barrel 30.

[0058] Furthermore, the rotating blades 31 are driven to rotate by a motor installed on the outer wall of the drying barrel 30, and a heat exchanger is installed between the diversion pipe 32 and the motor.

[0059] See Figure 5 The rotating blades 31 are driven to rotate by a motor installed on the outer wall of the drying barrel 30. The motor transfers heat when it is working. By installing a heat exchanger between the motor and the diversion pipe 32, the heat generated by the motor is conducted to the gas in the pipe, which can further dry the feed inside the drying barrel 30.

[0060] Furthermore, the moving tube 15 is slidably installed between the inner wall of the discharge port 14 and the inner wall of the inlet port 19. A rack 16 is fixedly installed on the outer wall of the moving tube 15. A second mounting seat 17 is fixedly installed on the top of the base plate 1. A rotatable gear 18 is installed on the outer wall of the second mounting seat 17, and the gear 18 meshes with the rack 16. A rotating plate 34 is rotatably installed on the inner wall of the inlet port 19, and a torsion spring is installed between the rotating plate 34 and the outer wall of the inlet port 19. When the moving tube 15 is disengaged from the rotating plate 34, the rotating plate 34 will close the inlet port 19. When the moving tube 15 moves down and rotates against the rotating plate 34, the rotating plate 34 will close the reuse pipe 33.

[0061] See Figure 6During the first run of the equipment, the gear 18 rotates clockwise, causing the rack 16 to move downwards. The moving tube 15 pushes against the rotating plate 34 until the rotating plate 34 is in contact with the inner wall of the feed inlet 19. The rotating plate 34 then closes the reuse pipe 33, connecting the discharge port 14 to the feed inlet 19 to complete the feed delivery. During the second run, the gear 18 rotates counterclockwise, causing the rack 16 to move upwards until the moving tube 15 is completely disengaged from the rotating plate 34. The rotating plate 34 then closes the feed inlet 19 and opens the reuse pipe 33. The second-collected feed, after drying, enters the launching channel 23 through the reuse pipe 33 and is then released onto the water surface. During the second run, only the recovered feed is delivered to prevent overfeeding, which can lead to indigestion and reduce the risk of disease. Furthermore, the initial feed delivery is usually of higher quality; separating it from the recovered and dried feed allows for better monitoring and management of feed quality, ensuring the fish receive balanced nutrition.

[0062] Furthermore, the top of the material cylinder 9 is provided with a feed inlet, and the feed inlet is equipped with a removable sealing cap 3. The outer wall of the material cylinder 9 is provided with several air inlets 35, and each air inlet 35 is equipped with moisture-absorbing cotton.

[0063] See Figure 3 as well as Figure 1 When the feed is about to be fed, the feed is put into the feed cylinder 9 through the feed inlet, and then the sealing cap 3 is installed on the feed inlet to prevent moisture from entering the feed cylinder 9 through the feed inlet. The feed cylinder 9 can draw air from the outside of the outer shell 2 through the air inlet 35, and the moisture-absorbing cotton inside the air inlet 35 can absorb the water vapor in the air to keep the feed inside the feed cylinder 9 dry and prevent it from getting damp and clumping.

[0064] Furthermore, a discharge port 36 is fixedly installed on the outer wall of the feeding body 20, and the opening of the discharge port 36 faces upward.

[0065] See Figure 5 The outlet 36 opens upwards. When the air in the connecting pipe 22 blows the feed in the launching channel 23 to the outside of the equipment, it will be lifted upwards by the outlet 36, which can increase the coverage of the feed, allowing more fish to obtain the feed at the same time. The feeding process is also smoother, reducing water surface ripples and stress response of the fish.

[0066] Furthermore, there are two filter plates 7, which can be opened and closed.

[0067] See Figure 1 When foreign objects and debris in the water block the filter holes on the filter plate 7, the filter plate 7 can be opened and the filter plate 7 and the inside of the collection chamber 6 can be cleaned.

[0068] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
