Description

Technical Field

[0001] The utility model relates to the technical field of fry screening, and more specifically, the utility model relates to a fry screening device. Background Art

[0002] Aquatic fry also include aquatic fish fry, and fish fry are also called "fish flowers" fish species. Juvenile fish hatched not long ago are generally 6-9 millimeters in body length. There are artificially propagated fry and natural fry from rivers; for juvenile fish hatched not long ago, they will move together with adult fish, resulting in mixed fishing during salvage. After salvage, staff need to screen them again. This screening method is inefficient, consumes a large amount of physical strength for staff, requires frequent monitoring and distinguishing of the size of fry, and is not convenient to operate. Therefore, a fry screening device is proposed for screening aquatic fry.

[0003] After retrieval, for example, a Chinese patent application with the publication number CN219395946U discloses an aquatic fry screening device, which is provided with a box body, a screening net and a discharge port. Water is filled into the box body, and then the fry to be screened are poured into the interior of the screening net. The fry are screened through the guidance of fish feed and discharged through the discharge port; it is provided with a screening net and a sieve net, and different sieves and screening nets can be replaced according to the size of different fry to realize the screening operation of fry with different requirements and reduce the limitation problem; it is provided with a protective cover, a support rod and a limiting convex block. By inserting the limiting convex block into the interior of the support rod, the insertion is realized through the limiting convex block, which is convenient for fixing the protective cover. Through the fixed position of the protective cover, the swimming of fry is guided.

[0004] However, when the above solution is used, the screening effect is achieved by guiding the fry to drill out of the screening net, and the efficiency is slow, making it difficult to be applied to large-scale aquaculture fry sites. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following describes the implementation manners of the present utility model by specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0029] As Figure 1 , 2 As shown in FIGS. 2 and 3, the present utility model provides a fry screening device, which includes a screening box 1 filled with water. A screening net 4 is movably arranged inside the screening box 1. Two connecting frames 7 are movably arranged at the upper end of the screening box 1 respectively. One side of the screening box 1 is communicated with a discharge port 5, and a switching valve 6 is fixedly arranged on the outer surface of the discharge port 5.

[0030] In order to improve the screening efficiency, shaking screening devices 2 capable of driving the screening net 4 to shake are arranged on both sides of the screening box 1 for driving the screening net 4 to shake to screen fry;

[0031] As Figure 3 shown, the shaking screening device 2 includes a waterproof box 21. The waterproof box 21 is fixedly arranged on one side of the inner wall of the screening box 1. A rotating rod 23 penetrates through the inside of the waterproof box 21. Both ends of the rotating rod 23 penetrate through both sides of the screening box 1 respectively. Sliding grooves 22 are respectively opened on both sides of the screening box 1. Rotating disks 27 are respectively fixedly arranged at both ends of the rotating rod 23. A transmission gear 24 is fixedly arranged on the outer surface of the rotating rod 23. The transmission gear 24 is located inside the waterproof box 21. A rotating motor 25 is fixedly arranged on one side of the screening box 1 through a flange. The output end of the rotating motor 25 penetrates through one side of the screening box 1. A rotating gear 26 is fixedly arranged at the output end of the rotating motor 25. The rotating gear 26 is meshed and connected with the transmission gear 24. One side of the rotating disk 27 is movably provided with a transmission rod 28 through a hinge seat. The upper end of the transmission rod 28 is movably connected with one side of the connecting frame 7 through a hinge seat. A slider 29 is fixedly arranged on one side of the connecting frame 7. The slider 29 is located inside the sliding groove 22. By driving the rotating gear 26 to rotate through the rotating motor 25, the transmission gear 24 and the rotating rod 23 can be driven to rotate, so that the two rotating disks 27 are forced to rotate. When the rotating disk 27 rotates, the transmission rod 28 is driven to swing. Since the transmission rod 28 is movably connected with the connecting frame 7 through a hinge seat, and since rollers are arranged on both sides of the slider 29, the two sliders 29 can be driven to slide in the sliding grooves 22, and the connecting frame 7 can be driven to move up and down. The overall effect of shaking the screening net 4 can be achieved, enabling smaller fry to follow the water flow through the screening net 4, realizing the screening effect and improving the screening efficiency.

[0032] Furthermore, in order to facilitate the installation and removal of the screening mesh 4, two screening mesh installation devices 3 capable of installing the screening mesh 4 are respectively provided between the two connecting frames 7 for installing the screening mesh 4 between the two connecting frames 7.

[0033] As Figure 4 shown, the screening mesh installation device 3 includes a support plate 32 which is fixedly arranged at the lower end of the connecting frame 7. An insertion block 33 is fixedly provided at the upper end of the support plate 32. A rotating block 34 is hinged on the outer surface of the insertion block 33. Slots 35 are respectively formed on both sides of the screening mesh 4. Two handles 31 are provided at the upper end of the screening mesh 4. The slots 35 are adapted to the rotating blocks 34. By dragging the screening mesh 4 with the support plate 32 and inserting the rotating blocks 34 and the insertion blocks 33 into the slots 35, and rotating the rotating blocks 34, the screening mesh 4 can be limited, so that the screening mesh 4 is clamped between the support plate 32 and the rotating blocks 34. Therefore, the effect of conveniently installing the screening mesh 4 can be achieved. When the shaking screening device 2 works, it can drive the screening mesh 4 to shake and screen. After the screening is completed, by rotating the rotating blocks 34 and pulling the handles 31, the screening mesh 4 can be conveniently removed.

[0034] The working principle is as follows: When the present utility model is in use, the screening mesh 4 is installed on the support plate 32 through the screening mesh installation device 3. Water is pumped into the present utility model by a water pump, and then the seedlings are poured onto the screening mesh 4. The rotating motor 25 is started to drive the screening mesh 4 to shake up and down by the shaking screening device 2, so that the water in the present utility model circulates through the gaps of the screening mesh 4, and the smaller seedlings are taken out of the screening mesh 4, thereby achieving the screening effect of the seedlings, improving the screening efficiency, and being able to conveniently disassemble and assemble the screening mesh 4, improving the convenience of the present utility model.

[0035] In addition, it is worth noting that the control processes of electronic devices such as the rotating motor 25 in the present utility model are all realized by a controller. The control circuit and structure of this controller are all mature prior arts, so they will not be further described in the present utility model.

[0036] Although the present utility model has been described in detail above with general descriptions and specific embodiments, on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
