Description

Technical Field

[0001] This utility model relates to the field of aquaculture feeding technology, specifically an automatic feeding device for aquaculture. Background Technology

[0002] Feeding strategies and feed selection are crucial for ensuring aquaculture efficiency and animal health. While current feeders can deliver feed at set times and in measured quantities, different aquatic animals have varying nutritional needs. For example, filter-feeding silver carp and bighead carp are best fed powdered feed (which expands slowly), while predatory fish like sea bass and rainbow trout prefer soft pellet feed. Therefore, appropriate feeds should be selected based on their biological characteristics and growth stages, and fed according to a scientific formula. Practical experience and field investigations have shown that current artificial aquaculture feeders can only deliver finished feed, not feed pelleted feed, let alone further powder-coating pelleted feed. Therefore, to better meet the feeding needs of different fish species, the aforementioned feeders need slight modifications. Utility Model Content

Throughout the invention, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] It should be understood that ordinal numbers and directional descriptions, such as "first," "second," "third," "upper," "lower," "left," and "right," are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, they should not be construed as limitations on this utility model.

[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. This application provides an automatic feeding device for aquaculture, including a recovery device 40, a mixing device 10, and a casing disposed at the bottom of the mixing device 10. The mixing device 10 is embedded in the casing, and a feed wrapping plate 20, a feed dispensing plate 30, and a discharging mechanism 50 are respectively installed from top to bottom inside the casing. The feed wrapping plate 20 and the feed dispensing plate 30 are vertically opposed and inclined inside the casing. The discharging mechanism 50 is located at the bottom of the feed dispensing plate 30 near the upper part of the inner wall of the casing. The inner wall of the casing is inclined. The recovery device 40 is located at the back of the casing. The mixing device 10 is installed to better scientifically proportion the feed, thereby meeting the nutritional needs of fish at different growth stages. The coating process helps fish better absorb and utilize nutrients in the feed, reducing waste and improving feed utilization and aquaculture efficiency. Simultaneously, the coating plate 20 and the recycling device 40 can coat the feed pellets with powder. The powdered feed pellets are less likely to disperse in the water, reducing feed waste, improving feed utilization, and enhancing the palatability and flavor of the feed, making fish more willing to eat, thus increasing feed intake. It can also be used for different types of fish. For example, predatory fish like sea bass and rainbow trout can be coated with shrimp powder to increase their attraction to predatory fish, while filter-feeding silver carp and bighead carp can use powders rich in protein and fiber such as cornmeal and soybean meal to promote their further growth. The feeding plate 30 and the discharging mechanism 50 can then release the powdered feed into the surface area of ​​the aquaculture water.

[0023] The mixing device 10 consists of a mixing bin 101, an extrusion bin 102, and a discharge pipe 103. The mixing bin 101 is equipped with opposing augers 111, and the extrusion bin 102 is located at the bottom of the mixing bin 101 to receive the material discharged from the mixing bin 101. The extrusion bin 102 is equipped with an extrusion auger 121, and the discharge pipe 103 is located at the tail end of the extrusion bin 102 and is in communication with the extrusion bin 102. The opposing augers 111 in the mixing bin 101 can form cutting conditions with the bin wall of the mixing bin 101 to cut and mix large pieces of raw feed. Then, the feed is sent into the extrusion bin 102 for compaction. Finally, the extrusion auger 121 further feeds and cuts the feed to form pellets.

[0024] The discharge mechanism 50 consists of a feeding plate 501, a brush roller 502, a tipping roller 503, an adjusting rod 504, a feeding belt 505, and a vibrating plate 506. The vibrating plate 506 is installed on the opposite side of the discharge plate 30, and the vibrating plate 506 is kept moving up and down by a vibrating motor located at the bottom of the vibrating plate 506. The feeding plate 501 is connected to the bottom of the discharge plate 30 by the adjusting rod 504. The brush roller 502 and the tipping roller 503 are respectively installed at the front and rear positions inside the feeding plate 501. The feed plate 501 is kept in contact with the vibrating plate 506; the adjusting rod 504 is used to adjust the height of the feed plate 501; the brush roller 502 can evenly coat the powder on the surface of the pellets; the excess powder is shaken off to the bottom of the machine box by the vibrating plate 506; then the tipping roller 503 conveys the pellets coated with powder to the feeding belt 505 for throwing and feeding; although the discharge mechanism 50 in this application is not the best embodiment, as an embodiment, its main purpose is to throw the pellet feed in an orderly manner.

[0025] Please see Figure 1 , 4 As shown, the recycling device 40 mainly includes a recycling box 401 and a lifting auger 402. The lifting auger 402 is installed at an incline inside the recycling box 401. The tail end of the lifting auger 402 is embedded in the inner bottom wall of the casing. There is a movable door between the recycling box 401 and the casing. A wrapping roller 403 is installed inside the recycling box 401 on the inner side of the movable door. One end of the wrapping plate 20 is flush with the opening of the recycling box 401. The wrapping roller 403 is installed on the wrapping plate 20. The wrapping roller 403 consists of a drive shaft 431 and three hoppers 432 evenly arranged on the side of the drive shaft 431.

[0026] As an example, it should be noted that the recycling bin 401 uses the lifting auger 402 to transport the powder that has fallen out of the machine box for reuse. There is a movable door between the recycling bin 401 and the machine box, which is opened and closed by elastic potential energy. When the coating roller 403 in the recycling bin 401 scrapes the powder to the movable door, it is squeezed and sent into the coating plate 20 to fully coat the powder with the particles. The two coating rollers 403 on the coating plate 20 are located on both sides of the bottom of the feed pipe 103. The powder is scraped up by the hopper 432 and mixed and stirred with the particles that fall on the coating plate 20, so that the powder adheres to the surface of the particles.

[0027] Furthermore, the feeding plate 30 is set with a gently sloping slope, and a set of brush rollers 502 is installed between the top of the feeding plate 30 and the wrapping plate 20. The brush rollers 502 are used to feed the wrapping particles accumulated on the feeding plate 30 in sequence. The rotation of the brush rollers 502 slowly drops the wrapping particles to one end of the feeding plate 30, and rolls them from the feeding plate 30 to the vibrating plate 506.

[0028] Please refer to the following: Figure 2As shown, an extrusion mesh 132 is nested at the bottom of the feeding pipe 103. A cutting machine 131 is installed at the bottom of the extrusion mesh 132, and the blade of the cutting machine 131 is aligned with the extrusion mesh 132. The feeding pipe 103 feeds material through the extrusion auger 121, and then the material is extruded through the extrusion mesh 132 with round holes. The cutting machine 131 cuts the raw material below the extrusion mesh 132 into granules, which fall onto the wrapping plate 20 for wrapping.

[0029] Please refer to the following: Figure 3 , 5 As shown, the surface of the feeding belt 505 is concave in an arc shape and extends to the bottom of the feeding plate 501; the tip of the tipping roller 503 has a tipping bucket that can scrape up the material particles in an arc shape. After the above-mentioned coating step is completed, the particles that fall on the vibrating plate 506 will shake off the excess powder through vibration. At the same time, the contact area between the vibrating plate 506 and the bottom of the brush roller 502 and the tipping roller 503 is also set to be concave in an arc shape. The brush roller 502 on the inner side of the feeding plate 501 will scrape the particles in an orderly manner to the tipping roller 503. Then, the tipping roller 503 will lift the feed through the tipping bucket at its end and raise it to the feeding plate 501. When the feeding plate 501 orderly feeds the feed through the inertia of the high-speed rotation of the feeding belt 505, the pellet feed will be scattered through the opening on the bottom side of the machine box.

[0030] It should be noted that each driving device in this application, including the opposed auger 111, the extrusion auger 121, the cutting machine 131, the lifting auger 402, the wrapping roller 403, the brush roller 502, the tipping roller 503, the feeding belt 505, and the vibrating plate 506, is driven by a motor, and a distribution box is installed outside the machine casing. The feed output is adjusted by controlling the driving power of each component after debugging.

[0031] In summary, the automatic feeding device for aquaculture described in this utility model can scientifically formulate feed into soft pellets or powder pellets according to the nutritional requirements of fish at different growth stages. Through this application, automatic, timed, and quantitative feeding is achieved, reducing labor costs and minimizing feed waste.

[0032] The above description is merely an embodiment of this utility model. Common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and they will not affect the implementation effect of this utility model or the practicality of the patent.
