[0002] Aquaculture is the cultivation of aquatic economic animals and plants using available waters, utilizing aquaculture techniques and facilities according to the ecological habits of the species and their environmental requirements. It is a branch of agricultural production and is categorized into marine aquaculture and freshwater aquaculture based on the nature of the waters. Aquaculture is further categorized by the species being cultivated and planted, including fish, shrimp, crabs, shellfish, algae, water chestnuts, lotus, and lotus roots.

[0003] Currently, most aquaculture is carried out on a large scale, and large-scale aquaculture requires a large amount of feed. Traditionally, feeding is done manually, but this method is time-consuming and tiring for the operator. To address this, those skilled in the art have employed feeding devices. However, existing aquaculture feeding devices are fixed in position, forcing the aquacultured animals to concentrate in one place to forage. This concentrated foraging can lead to increased competition among the aquacultured animals, and some of the aquacultured animals may fight over food, resulting in injury or even death. Therefore, an aquaculture feeding device is proposed. Utility Model Content

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] Reference Figures 1 to 3The embodiment of the utility model provides an aquaculture feeding device, comprising a support frame 10, a silo 20, a sprayer 30, a fan 40 and a swing assembly 50. The support frame 10 comprises support legs and horizontal support rods and vertical support rods arranged on the support legs, and a plurality of horizontal support rods form a horizontal mounting platform. The silo 20 is arranged above the horizontal mounting platform, the silo 20 is funnel-shaped, and the discharge port of the silo 20 faces downward. The feed is placed in the silo 20, the discharge port of the silo 20 is opened, and the feed flows out of the discharge port of the silo 20 under the action of gravity. The fan 40 and the sprayer 30 are both arranged on the horizontal mounting platform, the fan 40 is fixedly connected to the horizontal mounting platform, and the sprayer 30 is rotatably connected to the horizontal mounting platform. The sprayer 30 is a hollow sprayer 30, and one end of the sprayer 30 is an air inlet and the other end is a spray port. The cross-section of the feeder 30 of the embodiment of the present invention is rectangular, and the end of the feeder 30 close to the fan 40 is an air inlet. The air outlet of the fan 40 is connected to the air inlet of the feeder 30, so that the wind generated by the fan 40 flows into the air inlet of the feeder 30 and flows out from the feed outlet of the feeder 30. A feed inlet is provided on the upper surface of the feeder 30, and the feed inlet is connected to the feed outlet of the silo 20 through the feed rail 61. The feed flowing out of the silo 20 flows into the feeder 30 through the feed rail 61 and the feed inlet of the feeder 30, and the feed flowing into the feeder 30 is carried by the wind passing through the feeder 30 and blown out of the feeder 30. It should be noted that the feed in the embodiment of the present invention is a pellet or granular feed of relatively light weight. When the feed falls into the area where the wind generated by the fan 40 flows through, it can be blown into the water area of ​​aquaculture by the wind. The swing assembly 50 includes a spring 51 and an eccentric weight 52, which are respectively arranged on either side of the spray bin 20. Specifically, one end of the spring 51 is fixedly connected to a vertical support rod, and the other end is fixedly connected to the side wall of the sprayer 30. The eccentric weight 52 is arranged on the side of the bin 20 away from the spring 51. Optionally, the spring 51 and the eccentric weight 52 are on the same horizontal plane. A first drive motor 53 is mounted on a horizontal support rod, and the eccentric weight 52 is mounted on the output shaft of the first drive motor 53. It should be noted that the spring 51 is in a compressed state, so that the side of the sprayer 30 away from the spring 51 is always in contact with the eccentric weight 52.

[0030] When feeding, the feed is placed in the hopper 20. When the discharge port of the hopper 20 is opened, the feed enters the feeder 30 through the feed rail 61 and the feed port of the feeder 30. The air generated by the fan 40 flows into the feeder 30 from the air inlet of the feeder 30 and then flows out from the discharge port of the feeder 30, blowing the feed out of the feeder 30 to achieve the feeding. During this process, the first drive motor drives the eccentric block 52 to rotate, and the eccentric block 52 periodically squeezes the feeder 30 to move in the direction of the spring 51, thereby achieving the periodic swing of the feeder 30 and the periodic change in the direction of the feeder 30 spraying. This increases the feeding area, thereby avoiding the situation where the feeder 30 is fixed in the feeding position, causing the farmed animals to fight due to concentrated foraging and causing injury or death to the farmed animals.

[0031] Furthermore, the sprayer 30 is rotatably connected to the horizontal mounting platform. Specifically, a rotating shaft 54 ​​is provided on the lower surface of the sprayer 30 near the end of the blower 40, and the rotating shaft 54 ​​is fixedly connected to the sprayer 30. A limiting ring 55 is provided at the end of the rotating shaft 54 ​​away from the sprayer 30, and the support frame 10 is provided with a limiting groove corresponding to the limiting ring 55. The diameter of the bottom section of the limiting groove is larger than the diameter of the notch section, and the diameter of the bottom section is slightly larger than the diameter of the limiting ring 55. The diameter of the notch section is slightly larger than the diameter of the rotating shaft 54, and the limiting ring 55 is sleeved in the bottom section of the limiting groove. The rotating shaft 54 ​​of the embodiment of the present utility model is vertically arranged, that is, when the sprayer 30 swings periodically, its spray port swings on the horizontal plane.

[0032] To increase the distance between the feed's landing point in the aquaculture waters and the feeding device, the feeding device is tilted upward. A horizontal plate 31 is provided on the lower surface of the feed sprayer 30. The lower surface of the plate 31 mates with the upper surface of a horizontal support rod of a support frame 10. The coupling of the rotating shaft 54 ​​and the plate 31 stabilizes the tilted feed sprayer 30 on the support frame 10. A vertical support rod is provided at one end of the horizontal support rod mates with the plate 31, to which one end of a spring 51 is secured.

[0033] Furthermore, an air inlet 32 ​​is provided at one end of the sprayer 30, near the fan 40. This air inlet 32 ​​is connected to the air outlet of the fan 40 via a hose (not shown). This technical solution ensures that when the sprayer 30 swings, driving the air inlet 32 ​​to swing, the hose still ensures that air from the fan 40 flows into the sprayer 30. Optionally, the fan 40 is a blower 40.

[0034] Furthermore, the feed rail 61 is rotatably connected to the support frame 10. A connecting rod 62 is rotatably connected to one end of the lower surface of the feed rail 61. The other end of the connecting rod 62 is mounted on the output shaft of a second drive motor 63, and the connecting rod 62 is fixedly connected to the output shaft of the second drive motor 63. When the second drive motor 63 drives the connecting rod 62 to rotate, the connecting rod 62 drives the feed rail 61 to rotate. When the feed rail 61 rotates to a first angle (at which point the feed rail 61 is horizontal), the feed rail 61 blocks the discharge port of the silo 20. A feed barrel 33 is provided on the upper surface of the injector 30, one end of which is connected to the feed port of the injector 30. When the feed rail 61 rotates to the second angle (at which point the feed rail 61 is tilted), it separates from the outlet of the silo 20, opening the outlet of the silo 20. Simultaneously, the lower end of the feed rail 61 aligns with the feed barrel 33, allowing feed to flow through the feed rail 61 into the injector 30. It should be noted that during the swinging of the injector 30, the end of the feed rail 61 closest to the feed barrel 33 remains above the opening of the feed barrel 33. The feed rail 61 is rotatable between the first and second angles.

[0035] Furthermore, a discharge barrel 34 is provided on the lower surface of the feed injector 30. Some of the feed flowing into the feed injector 30 may not be blown out, and this part of the feed flows out of the feed injector 30 through the discharge barrel 34 to avoid accumulation in the feed injector 30 and flow into the fan 40.

[0036] Furthermore, the aquaculture feeding device includes a protective housing 70, within which the feed silo 20, the feed sprayer 30, the fan 40, and the swing assembly 50 are all disposed. The upper end of the protective housing 70 is open, and the feed silo 20 is fixed to the protective housing 70, with the upper surface of the protective housing 70 and the upper surface of the feed silo 20 being coplanar. The side of the protective housing 70 has an opening for the feed sprayer 30 to spray feed.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
