Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and in particular to a device for controlling residual feed and directing feeding in a fish-vegetable symbiosis system. Background Technology

[0002] Aquaponics is a farming method that combines aquaculture and hydroponics to form a circular system. Its basic principle is that fish excrement is decomposed into nutrients that plants can absorb by microorganisms in the water. After the plants absorb the nutrients, they purify the water, and the clean water flows back into the fishpond, achieving the effect of "raising fish without changing the water and growing vegetables without fertilizing".

[0003] In existing technologies, feeding devices typically use either fixed or tray-type methods. Fixed feeding devices can only feed fish in a fixed area. However, in aquaculture ponds, fish tend to congregate in different areas due to factors such as water temperature, dissolved oxygen, and light. Fixed feeding devices can only feed at fixed points, leading to intense competition for food in some areas and insufficient feeding in others, affecting the overall uniformity of growth. Furthermore, uneaten food tends to sink to the bottom of the pond after the fish have eaten their fill. While tray-type feeding can distribute food evenly, the different areas where fish congregate result in insufficient food in densely populated areas and excessive food in sparsely populated areas. This leads to food surplus in areas with fewer fish, also resulting in uneaten food. Uneaten food decomposes under the influence of microorganisms, producing harmful substances such as ammonia nitrogen and nitrite, disrupting the nitrogen cycle balance in the water, increasing the water purification load of the aquaponics system, and potentially causing diseases in both fish and plants.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0017] like Figure 1-7 As shown, a directional feeding device for controlling uneaten feed in an aquaponics system includes a gantry mechanism 1, a moving mechanism 2, a positioning mechanism 3, and a feeding mechanism 4. The gantry mechanism 1 is mounted above the aquaponics pond via the moving mechanism 2, and the moving mechanism 2 can move the gantry mechanism 1 left and right. The feeding mechanism 4 is mounted on the gantry mechanism 1 via the positioning mechanism 3, and the positioning mechanism 3 can move the feeding mechanism 4 in the forward-backward and vertical directions. The gantry mechanism 1 moves left and right above the aquaponics pond via the moving mechanism 2, causing the feeding mechanism 4 to move left and right. Simultaneously, the positioning mechanism 3 can move the feeding mechanism 4 in the forward-backward and vertical directions, enabling the feeding mechanism 4 to move in any direction in three-dimensional space. This allows the feeding mechanism 4 to be moved to any location in the aquaponics pond to feed the fish based on their aggregation patterns.

[0018] The gantry mechanism 1 includes a crossbeam 11 and support legs 12. The crossbeam 11 is horizontally arranged front and back. There are two support legs 12, which are vertically arranged on the front and back sides of the bottom of the crossbeam 11, respectively. The bottom of the support legs 12 is connected to the moving mechanism 2. The crossbeam 11 and the support legs 12 form a gantry structure. The moving mechanism 2 drives the gantry structure to move, thereby driving the feeding mechanism 4 to move and adjusting the position of the feeding mechanism in the left and right directions.

[0019] The moving mechanism 2 includes a ground rail 21, a moving rack 22, a mounting base 23, a moving motor 24, a moving gear 25, and moving rollers 26. Two ground rails 21 are provided, horizontally positioned on either side of the aquaculture pond. The moving racks 22 are horizontally positioned on opposite sides of the two ground rails 21. The top surface of the mounting base 23 is fixedly connected to the bottom surface of the support leg 12. The moving motor 24 is mounted on the mounting base 23, with its output shaft passing downwards through the mounting base 23. The moving gear 25 is fixedly sleeved on the output shaft of the moving motor 24 and meshes with the moving rack 22. The moving rollers 26 are rotatably positioned on the front and rear sides of the bottom surface of the support leg 12 and contact the top surface of the ground rail 21. The rotation of the output shaft of the moving motor 24 drives the moving gear 25 to rotate on the moving rack 22, thereby causing the gantry support leg 12 to move along the ground rail 21 via the moving rollers 26, thus realizing the left and right movement of the gantry mechanism 1.

[0020] The moving mechanism 2 further includes a guide wheel seat 27 and a moving guide wheel 28. The guide wheel seat 27 is vertically disposed on the front and rear sides of the bottom surface of the support leg 12, with its left and right sides extending outwards from the left and right sides of the ground rail 21. The moving guide wheel 28 is rotatably disposed on the left and right sides of the bottom surface of the guide wheel seat 27 and contacts the side of the ground rail 21. The moving guide wheel 28 limits the left and right sides of the support leg 12 of the gantry mechanism 1 to prevent tipping and assists the support leg 12 in moving, ensuring the moving stability of the gantry mechanism 1.

[0021] The positioning mechanism 3 includes a front and rear positioning component 31 and an upper and lower positioning component 32. The front and rear positioning component 31 includes a positioning rack 311, a side plate 312, a base plate 313, a positioning motor 314, and a positioning gear 315. The positioning rack 311 is located at the bottom of the crossbeam 11. The side plate 312 is vertically arranged on the left and right sides of the crossbeam 11. The base plate 313 is horizontally fixed at the bottom of the two side plates 312, and its front and rear sides extend forward and backward. The positioning motor 314 is horizontally located on the right side of the top surface of the base plate 313, and its output shaft faces to the left. The positioning gear 315 is fixedly sleeved on the output shaft of the positioning motor 314 and meshes with the positioning rack 311. The upper and lower positioning component 32 is located on the left side of the top surface of the base plate 313. The output shaft of the positioning motor 314 rotates, driving the positioning gear 315 to rotate on the positioning rack 311, causing the side plate 312 and the bottom plate 313 to move back and forth on the crossbeam 11, thereby driving the feeding mechanism 4 to move back and forth on the crossbeam 11 and adjusting the position of the feeding mechanism in the front and back directions.

[0022] The front and rear positioning assembly 31 further includes an upper support roller 316, a lower support roller 317, and a guide roller 318. The upper support roller 316 is rotatably mounted on the upper part of each of the two side plates 312 on opposite sides, with two rollers positioned front and rear, and contacts the top surface of the crossbeam 11. The lower support roller 317 is rotatably mounted on the lower part of each of the two side plates 312 on opposite sides, with two rollers positioned front and rear, and contacts the bottom surface of the crossbeam 11. The guide rollers 318 are respectively located on opposite sides of the two side plates 312, and the guide rollers 318 on each side plate 312 are arranged in a rectangular distribution, with the side of the guide roller 318 closest to the crossbeam 11 contacting the side of the crossbeam 11. The upper support roller 316 and lower support roller 317 limit the upper and lower parts of the positioning mechanism 3 to prevent it from falling, and simultaneously assist the positioning mechanism 3 in moving back and forth, ensuring the stability of the positioning mechanism 3.

[0023] The aforementioned upper and lower positioning assembly 32 includes a positioning cylinder 321; the positioning cylinder 321 is vertically disposed on the left side of the top surface of the base plate 313, and its piston rod passes downward through the base plate 313. The piston rod of the positioning cylinder 321 extends and retracts, driving the feeding mechanism to move in the vertical direction, thereby adjusting the position of the feeding mechanism in the vertical direction; during feeding, the positioning cylinder 321 drives the feeding mechanism to descend, lowering the feeding height to prevent the bait from falling from a high height and breaking, thus preventing the fish from fully consuming the bait and resulting in bait residue.

[0024] The feeding mechanism 4 includes a connecting plate 41, a bait box 42, a feeding assembly 43, and a discharging assembly 44. The connecting plate 41 is horizontally fixed to the bottom surface of the piston rod of the positioning cylinder 321. The bait box 42 is fixedly mounted on the bottom surface of the connecting plate 41. The bait is placed into the bait box 42 through the feeding assembly 43 and stored therein. During feeding, the bait is discharged through the discharging assembly 44.

[0025] The feeding assembly 43 includes a feeding hopper 431 and a feeding pipe 432; the lower end of the feeding pipe 432 is connected to the inside of the bait box 42; the bottom of the feeding hopper 431 is connected to the upper end of the feeding pipe 432. The feeding hopper 431 and the feeding pipe 432 facilitate the feeding of bait into the bait box 42.

[0026] The discharge assembly 44 includes a discharge motor 441, a sleeve 442, a rotating shaft 445, and a spiral blade 446. The sleeve 442 is horizontally arranged front to back and hollow inside. It has an inlet 443 on the front side of the top surface and an outlet 444 on the rear side of the bottom surface. The discharge motor 441 is located at the rear end of the sleeve 442, and its output shaft enters the sleeve 442 and can rotate inside the sleeve 442. The rotating shaft 445 is horizontally arranged front to back inside the sleeve 442. One end of the shaft is fixedly connected to the output shaft of the discharge motor 441, and the other end is rotatably connected to the rear side wall of the sleeve 442 through a bearing. The spiral blade 446 is mounted on the rotating shaft 445. When feeding is required, the output shaft of the discharge motor 441 rotates, driving the rotating shaft 445 and the spiral blade 446 to rotate, forming a spiral feeding structure, thereby sending the bait in the bait box 42 out through the spiral blade 446 and falling from the discharge port 444 to feed the fish.

[0027] The mobile motor 24, positioning motor 314, positioning cylinder 321 and discharge motor 441 are controlled by a PLC control system. After determining the area where fish gather, the system can automatically feed the fish in that area.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
