Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and more specifically to a net cage for hatching aquatic animal seedlings. Background Art

[0002] Aquaculture is the production of aquatic plants and animals in suitable waters. It is an important component of the fishery industry. Cage aquaculture, in which fish fry are raised in cages of specific sizes, accumulates at the bottom of the cages. This accumulation of fish excrement contaminates the water around the cages, requiring regular, labor-intensive, and time-consuming manual cleaning. In light of this, we propose a cage for hatching aquatic animal fry. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a hatching cage for aquatic animal fry to solve the current technical problem of time-consuming and labor-intensive excrement cleaning.

[0004] In order to solve the above technical problems, the present utility model provides the following technical solutions: a cage for hatching aquatic animal seedlings, comprising a cage frame, a plurality of outer protective nets installed on the outside of the cage frame, a plurality of bottom plates provided at the bottom of the cage frame, discharge openings provided between adjacent bottom plates, a discharge structure provided inside the discharge opening, a fish blocking structure provided above the plurality of discharge structures in the lower half of the cage frame, and a driving structure provided below the discharge structure.

[0005] Preferably, the discharge structure includes a straight plate and a plurality of inclined plates connected to the straight plate, the straight plate is located at the center of the discharge port, the inclined plate is arranged to be inclined outward, and the plurality of inclined plates are symmetrically and equidistantly distributed on both sides of the straight plate, and the periphery between the straight plate and the two inclined plates in the same plane is adapted to the discharge port.

[0006] Preferably, the fish blocking structure includes a first filter plate and a second filter plate, the filter mesh holes of the first filter plate and the second filter plate are staggered, the first filter plate is fixed to the inner side of the cage frame, and the second filter plate is connected to a connecting rod, which passes through the first filter plate and is connected to a straight plate in a relative position.

[0007] Preferably, the driving structure includes a special-shaped plate and a connecting rod, the bottom of the special-shaped plate is connected to a plurality of straight plates, a protruding block is provided on one side of the special-shaped plate, the protruding block is installed with a connecting rod, and the top end of the connecting rod is connected to a cylinder.

[0008] Preferably, a frame plate is installed on the outside of the cylinder, and the frame plate is fixed to the cage frame.

[0009] Preferably, ramp plates are provided on both sides of the discharge structure, and the ramp plates are arranged in an inclined manner and connected to the bottom plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model uses the inclined plate slope structure and the connection between the special-shaped plate, connecting rod and cylinder. When the cylinder is activated, it can drive the straight plate to rise and fall. Combined with the design of the inclined plate, the excrement will slide toward the inclined plate. When the inclined plate drops below the discharge port, the slope design allows the excrement on the inclined plate to fall to the bottom of the lake or river. The excrement is discharged manually by mechanical automatic means, solving the problem of time-consuming and labor-intensive excrement cleaning.

[0012] 2. The utility model also plays a role in blocking the fry by staggered cooperation of the filter screens of the first filter plate and the second filter plate. At the same time, in the cleaning process, the first rising action drives the connecting rod to move, so that the second filter plate rises and drives the fry away. The continuous movement continuously drives the fry away. The excrement at the filter plate position can fall to the bottom through the separate movement of the two filter plates. At the same time, the design of the outer fitting between the discharge port and the straight plate and the inclined plate makes it possible to drive away the fry during the process of discharging the excrement due to the continuous movement of the inclined plate. Combined with the fact that the discharge port is always closed, it further plays a role in preventing the fry from escaping. It automatically cleans the excrement while driving away the fry, and prevents the fry from escaping, further solving the problem that the fry are easy to escape when cleaning the excrement.

[0021] like Figures 1 to 4 As shown, the utility model relates to a hatching cage for aquatic animal seedlings, comprising a cage frame 1, a plurality of outer protective nets 2 are installed on the outside of the cage frame 1, a plurality of bottom plates 3 are arranged at the bottom of the cage frame 1, the sides of the bottom plates 3 are fixed to the cage frame 1, a plurality of bottom plates 3 are adjacently provided with discharge ports 4, a discharge structure 5 is provided inside the discharge port 4, the discharge structure 5 comprises a straight plate 501, the straight plate 501 is located at the center of the discharge port 4, the straight plate 501 and the discharge port 4 have the same length on both long axis sides, a plurality of inclined plates 502 are installed on the two long axis sides of the straight plate 501, the plurality of inclined plates 502 are arranged to be inclined outward, and the plurality of inclined plates 502 on both sides of the straight plate 501 are symmetrically distributed, and the plurality of inclined plates 502 on the same side are fixed to the straight plate 501 at equal distances, and ramp plates 8 are arranged on both sides of the discharge structure 5, the ramp plates 8 are inclined and connected to the bottom plate 3, and the inclined design of the ramp plates 8 can make excrement fall to the discharge port 4 position;

[0022] In order to drive the straight plate 501 to move, a driving structure 7 is provided under the discharge structure 5. The driving structure 7 includes a special-shaped plate 701 and a connecting rod 702. The special-shaped plate 701 is an E-shaped structure. The bottom of the special-shaped plate 701 is connected to multiple straight plates 501. A protruding block is provided on one side of the special-shaped plate 701. The protruding block is installed with a connecting rod 702. The connecting rod 702 serves to extend the driving end of the cylinder 703 to avoid the problem of damage caused by direct contact between the cylinder 703 and the water. The top of the connecting rod 702 is connected to the cylinder 703, and a frame plate 704 is installed on the outside of the cylinder 703. The frame plate 704 is fixed to the cage frame 1. When the cylinder 703 acts, it can drive the connecting rod 702 to rise and fall, so that the special-shaped plate 701 drives the straight plate 501 to move, and the inclined plate 502 moves gradually to discharge the excrement. This process needs to be a slow moving process.

[0023] In the embodiment of the present invention, in order to drive away and prevent the fry from escaping when cleaning the excrement, a fish blocking structure 6 is provided above the multiple discharge structures 5 in the lower half of the cage frame 1. The fish blocking structure 6 includes a first filter plate 601 and a second filter plate 602. The first filter plate 601 and the second filter plate 602 are both structures of a mesh frame plus an internal fixed metal filter screen. The metal filter screens of the first filter plate 601 and the second filter plate 602 need to be in a state of mutual adhesion. The filter screen holes of the first filter plate 601 and the second filter plate 602 are The staggered holes are staggered to increase the mesh size of the filter, which can block the fry. The first filter plate 601 is fixed to the inner side of the cage frame 1. The second filter plate 602 is connected with a connecting rod 603. The connecting rod 603 passes through the first filter plate 601 and is connected to the straight plate 501 at the opposite position. When the straight plate 501 moves, the connecting rod 603 can be driven to move, so that the first filter plate 601 can be separated from the second filter plate 602. The second filter plate 602 slowly rises to drive the fry away from the bottom position.

[0024] Furthermore, the periphery between the straight plate 501 and the two inclined plates 502 in the same plane is adapted to the discharge port 4, which means that the periphery between the straight plate 501 and the two inclined plates 502 in the same plane is in contact with the inner wall of the discharge port 4. In the process of discharging excrement, the inclined plates 502 continue to rise and fall, which will further drive away the fry. Combined with the adaptation of the side contact, the discharge port 4 is always closed, which further prevents the fry from escaping.

[0025] Working principle: This embodiment provides a hatching cage for aquatic animal seedlings. When the excrement in the cage needs to be cleaned, the cylinder 703 is controlled by the external control structure to operate, driving the connecting rod 702 to move slowly, so that the special-shaped plate 701 drives the straight plate 501 to rise, and the straight plate 501 drives the connecting rod 603 to rise, so that the second filter plate 602 slowly rises. During the rising process, the fry are driven away, and at the same time, the first filter plate 601 and the second filter plate 602 are separated and moved, so that the excrement between the two filter plates can fall to the bottom (referring to larger particles of excrement), and through natural The falling body, combined with the inclination of the ramp 8, will concentrate the excrement at the position of the discharge port 4. After rising to the limit, it will then fall. During the falling process, the excrement will gradually fall onto the upper surfaces of the multiple ramps 502. Through slow descent, when the ramp 502 falls below the discharge port 4, the slope design makes the excrement on the ramp 502 fall to the bottom of the lake or river. At the same time, in the process of discharging excrement, the continuous lifting and moving of the ramp 502 will further drive away the fry. Combined with the adaptation of the side fitting, the discharge port 4 is always closed, which further prevents the fry from escaping.
