Description

Technical Field

[0001] The invention relates to the technical field of fishery breeding equipment, in particular to a factory-based fishery classification breeding box. Background Art

[0002] Fishery, also known as aquaculture, is a social industry sector that uses the material transformation function of organisms in water bodies to obtain aquatic products through fishing, breeding and processing. In order to increase production and reduce intermediate steps such as fishing and transportation, some factory-based aquaculture fisheries have gradually developed. Especially in recent years, breeding companies and breeders have increasingly tried factory-based aquaculture. Through a series of treatments such as physical filtration, biological purification, sterilization and disinfection, degassing and oxygenation of aquaculture water bodies, all or part of the aquaculture water can be recycled. The aquaculture process is fully controlled, with significant advantages such as water and land saving, energy saving for temperature control, stable aquaculture environment, fast growth of aquaculture organisms and reduced environmental pollution. It is known as the "most promising aquaculture model in the 21st century" and is an important direction and future development trend for my country's aquaculture transformation, structural adjustment, and low-carbon green development.

[0003] Existing factory farming generally directly places different fishery aquatic products together in the same group of breeding boxes for mixed breeding, or classifies aquatic products and breeds them separately in different breeding boxes. Because some aquatic products have a certain predation relationship, for example, some carnivorous fish will prey on shrimps and small fish, it is difficult to directly breed them together. In addition, different aquatic products require different water depths. Some shallow water fish like to swim in the middle and upper layers of the water layer, while some deep water fish like to swim in deep water areas. If they are directly separated, there will be fewer fish in the shallower waters of the deep water fish breeding box, resulting in a waste of part of the water space. To this end, we propose a factory farming fishery classification breeding box. Summary of the invention

DETAILED DESCRIPTION

[0029] 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.

[0030] Example 1

[0031] See also Figure 4-Figure 9 A factory-based fish farming classification breeding box shown in the figure includes a base 1, a partition mechanism 4, a rotating mechanism 7 and a cleaning mechanism 9. A fixed cylinder 2 is fixedly connected to the base 1, and rotating disks 3 are rotatably connected to both ends of the fixed cylinder 2. An opening 34 is opened on the upper side of the fixed cylinder 2, and a top cover 35 is hinged in the opening 34. An oxygenator 36 for oxygenating the fixed cylinder 2 is fixedly connected to the base 1, and a water changing device 37 for changing water in the fixed cylinder 2 is fixedly connected to the base 1. The partition mechanism 4 includes multiple groups of partition nets 5 installed in the fixed cylinder 2, and the multiple groups of partition nets 5 are arranged parallel to each other. Both sides of the partition nets 5 are provided with fitting rods 6 that fit with the inner wall of the fixed cylinder 2, which are used to separate and adjust the area in the fixed cylinder 2 by adjusting the position of the partition nets 5 and the fitting rods 6.

[0032] The rotating mechanism 7 includes an outer toothed ring 8 coaxially fixedly installed on the side surfaces of the rotating disk 3 on both sides, which is used for synchronously driving the outer toothed ring 8 on both sides to rotate, so that the rotating disk 3 and the dividing net 5 are rotated, and the inclination angle of the dividing net 5 is changed, thereby improving the efficiency of fishery breeding and enriching the breeding areas of different aquatic products. The cleaning mechanism 9 includes a cleaning plate 10 slidably connected to the side of the bonding rod 6, which is used for scraping the stains on the inner wall of the fixed cylinder 2 onto the bonding rod 6 when the separation mechanism 4 drives the bonding rod 6 to move, and synchronously drives the cleaning plate 10 to slide horizontally along the bonding rod 6 to scrape the impurities on the surface of the bonding rod 6.

[0033] The partition mechanism 4 also includes a mounting frame 11 fixedly mounted on both sides of the partition net 5, and guide grooves 12 are provided at both ends of the mounting frame 11. Two groups of connecting rods 13 are fixedly connected between the two groups of mounting frames 11. The two ends of the partition net 5 are fixedly connected to the connecting rods 13. An adjusting member 14 for adjusting the position state of the mounting frame 11 is provided on the rotating disk 3, and a partition 15 for combining and separating with the partition net 5 is provided on the fitting rod 6.

[0034] The partition 15 includes a rotating rod 16 rotatably connected to the two ends of the fitting rod 6, and the two rotating rods 16 are respectively rotatably connected to guide rods 17, the guide rods 17 are slidably connected to the inner wall of the guide groove 12, and a partition plate 18 is fixedly connected to the guide rod 17. The top surface of the partition plate 18 is slidably fitted with the bottom surface of the connecting rod 13, and an arc groove 19 is opened on the rotating disk 3 to slide with the outer wall of the rotating rod 16.

[0035] The adjusting member 14 includes an adjusting block 31 fixedly mounted on the side of the mounting frame 11 . An adjusting slot 32 is provided on the side of the rotating disk 3 . An electric telescopic rod 33 is fixedly connected in the adjusting slot 32 . The telescopic end of the electric telescopic rod 33 is fixedly connected to one side of the adjusting block 31 .

[0036] In this embodiment, the electric telescopic rod 33 drives the adjustment block 31 to slide in the adjustment groove 32, thereby changing the position of the mounting frame 11, and the mounting frame 11 drives the guide rods 17 on both sides to move synchronously, so that the rotating rod 16 drives the fitting rod 6 to fit the inner wall of the fixed tube 2 for movement and adjustment. Since the rotating rod 16 is limited by the arc groove 19, it is ensured that when moving, the side wall of the fitting rod 6 is always in contact with the fixed tube 2, thereby achieving the purpose of scraping and cleaning the inner wall of the fixed tube 2.

[0037] It should be noted that: the partition plate 18 is hard and a through hole can be opened in the middle. The partition net 5 can be hard or soft. The bottom surfaces of the connecting rods 13 on both sides of the partition net 5 are always in contact with the top surfaces of the partition plates 18, thereby ensuring that when the guide rod 17 slides in the guide groove 12, the connecting rod 13 and the partition plate 18 are always sealed, preventing aquatic products such as fish and shrimp from passing through the gap between the partition net 5 and the partition plate 18. When the rotating rod 16 moves in the arc groove 19, it will drive the cleaning mechanism 9 to operate, so that the cleaning plate 10 slides on the surface of the fitting rod 6, thereby removing impurities scraped off the surface of the fitting rod 6, thereby realizing a preliminary self-cleaning function.

[0038] The rotation state of the rotating disk 3 is controlled by the rotating mechanism 7, thereby driving the separation net 5 to rotate and changing the inclination angle of the separation net 5. When the separation net 5 is in a vertical state, it is easier to feed and catch aquatic products in different separated water areas from the opening 34 at the top. When the separation net 5 is in a horizontal state, the water depth required for each type of aquatic product is more obviously different. The upper layer aquatic products can only swim in the upper layer, and the lower layer aquatic products can only swim in deep water. When the separation net 5 is in an inclined state, the swimming depth range of each layer of aquatic products is wider. The aquatic products in the upper water area can swim in the middle and upper water area, the aquatic products in the lower water area can swim in the middle and lower water area, and the aquatic products in the middle water area can switch between different sections of the water area.

[0039] Example 2

[0040] See also Figure 1-Figure 2 Embodiment 2 is described. This embodiment further describes embodiment 1. The cleaning mechanism 9 shown in the figure also includes a driving block 20 fixedly mounted on the cleaning plate 10. A sliding groove 21 is provided on the fitting rod 6. The cleaning plate 10 and the driving block 20 are both slidably connected to the inner wall of the sliding groove 21 in a horizontal direction. A threaded rod 22 is rotatably connected in the sliding groove 21. Both ends of the threaded rod 22 are coaxially fixedly connected to the rotating rods 16 at both ends. The threaded rod 22 passes through the driving block 20 and is threadedly connected to the driving block 20. A rotating member 23 is provided in the arc groove 19 for linking the threaded rod 22 to rotate when the rotating rod 16 moves. Two groups of cleaning plates 10 are provided on the same fitting rod 6, and are symmetrically distributed on both sides of the driving block 20.

[0041] The rotating member 23 includes a first gear 24 coaxially fixedly mounted on the rotating rod 16, an arc-shaped rack 25 meshing with the first gear 24 is fixedly connected in the arc-shaped groove 19, and bellows 38 are fixedly connected on both sides of the driving block 20, and the side of the bellows 38 away from the driving block 20 is fixedly connected to the inner wall of the sliding groove 21.

[0042] When the rotating disk 3 rotates, the fitting rod 6 is driven to scrape off the impurities on the inner wall of the fixed cylinder 2. During this process, the position of the rotating rod 16 in the arc groove 19 remains unchanged, so the cleaning plate 10 will not move at this time. When the electric telescopic rod 33 drives the partition net 5 to move and adjust, the rotating rods 16 at both ends of the fitting rod 6 are driven to slide along the arc groove 19, so that the first gear 24 rotates along the arc rack 25. The first gear 24 drives the rotating rod 16 to rotate the threaded rod 22, so that the driving block 20 and the cleaning plates 10 on both sides can slide along the sliding groove 21, so as to achieve the purpose of self-cleaning of both sides of the fitting rod 6. The threaded rod 22 can be protected by the bellows 38. Similarly, a protective baffle can be set on the side of the arc groove 19 to reduce the situation where impurities enter the arc groove 19. Since the water quality in the fixed cylinder 2 is relatively clean, the impurities are only residual food and excrement, which will not cause jamming and direct damage to the operation of the mechanical structure in the fixed cylinder 2.

[0043] Example 3

[0044] See also Figure 1-Figure 11 Embodiment 3 is described. This embodiment further describes Embodiment 1. The rotating mechanism 7 shown in the figure includes a driving motor 26 fixedly mounted on the base 1. The driving motor 26 is preferably of model Y80M1-2. The output end of the driving motor 26 is coaxially fixedly connected with a driving shaft 27. Two groups of second gears 28 are fixedly connected to the driving shaft 27. The two groups of second gears 28 are respectively meshed with the outer gear rings 8 on both sides. A fixing frame 29 is fixedly connected to the base 1. A rotating shaft 30 rotatably connected to the fixing frame 29 is coaxially fixedly connected to the rotating disk 3.

[0045] In this embodiment, the driving motor 26 drives the driving shaft 27 to rotate, so that the second gears 28 on both sides synchronously drive the outer gear ring 8 to rotate, so that the rotating disk 3 on both sides and the rotating shaft 30 can rotate synchronously around the fixed frame 29. When it is necessary to clean the fixed cylinder 2, the aquatic products in the fixed cylinder 2 are fished out, and a certain amount of water is retained in the fixed cylinder 2. The driving motor 26 is started to drive the rotating disk 3 to rotate, and the electric telescopic rod 33 drives the dividing net 5 to move back and forth, so that the fitting rod 6 can continuously scrape the impurities on the inner wall of the fixed cylinder 2. At the same time, the connecting rod 13 can clean the impurities on the surface of the dividing plate 18, and the cleaning plate 10 can clean the impurities on the surface of the fitting rod 6. The internal water flow continuously passes through the dividing net 5 and the dividing plate 18, which is similar to a drum washing machine. It can effectively remove the residual impurities inside, and then the sewage is discharged from the bottom. The required clean water source can be replaced by the water changing equipment 37 to continue the breeding operation.
