Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a fish fry hatching device for aquaculture. Background Technology

[0002] In the natural environment, after the parent fish spawn and are fertilized, the fish eggs hatch on their own in waters with suitable conditions such as water flow and temperature. However, in artificial breeding, people will simulate natural conditions and create a better environment to improve the hatching success rate. For example, the Chinese utility model patent disclosed in announcement number CN221962589U: a fish fry hatching and breeding device. This application includes a breeding box, the inside of which is threaded with a plug, and a sealing groove is opened on the surface of the breeding box. A sealing gasket is slidably connected to the inner wall of the sealing groove, and an isolation plate is fixedly installed on the surface of the sealing gasket.

[0003] This application, like existing common fish fry incubation devices, uses a container with a certain volume to incubate fish eggs. After the fish fry have hatched, it is difficult for operators to quickly and efficiently remove them from the incubation container. They often need to carefully operate with additional tools, which is not only time-consuming but also easy to damage the fragile fish fry, affecting their survival rate and subsequent growth. Moreover, due to the lack of an effective structure to guide the fish fry to gather, the fish fry are relatively scattered in the container, further increasing the difficulty of removing them. Utility Model Content

[0004] The purpose of this invention is to provide a fish fry hatching device for aquaculture, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fish fry hatching device for aquaculture includes an outer casing with a top cover fixedly installed on it. An operating port is provided inside the top cover. A main controller is fixedly installed on the rear side of the outer casing. A circulation pump is fixedly installed on the top cover near the operating port, and the circulation pump is electrically connected to the port of the main controller via a connecting cable. An oxygenation pipe is fixedly installed at the lower end of the top cover near the circulation pump, and one end of the oxygenation pipe is connected to the output end of an oxygenation device inside the main controller via a pipe. A frame is also fixedly installed on the top cover, and a cylinder is fixedly installed on the frame. The cylinder is connected to an air pump inside the main controller via a connecting pipe. An inner casing is fixedly installed inside the outer casing, and a tray is inserted into the inner casing. Multiple first bearing seats are fixedly installed at the bottom of the tray, and the first bearing seats are movably connected to one end of the piston rod of the cylinder via a lifting mechanism.

[0007] As a further preferred embodiment of this utility model, a drain pipe is fixedly installed inside the inner box, and a drain pipe is also fixedly installed inside the outer box. A limit block is also fixedly installed on the upper side of one side of the inner box. The limit block on one side of the inner box can limit one end of the pallet that is raised inside the inner box, thereby providing conditions for changing the angle of the pallet.

[0008] As a further preferred embodiment of this utility model, overflow ports are provided on both the front and rear sides of the inner box. A filter screen is fixedly installed in the overflow port. The opening of the overflow port can control the highest water level in the inner box and facilitate the rapid discharge of water located above the tray in the inner box when the tray is lifted.

[0009] As a further preferred embodiment of this utility model, a water permeable opening is provided at the bottom of the tray, and a filter screen is fixedly installed inside the water permeable opening. The tray can lift the hatched fish fry from the inner box to a position close to the operating opening, thereby making it easier for personnel to take out the fish fry. At the same time, the water permeable opening can facilitate the rapid discharge of water located above the tray in the inner box when the tray is lifted, in conjunction with the overflow port.

[0010] As a further preferred embodiment of this utility model, a rubber pad is fixedly installed on the top of the tray along the contour, and the top of the rubber pad has a sloping structure and abuts against the inside of the inner box. The rubber pad can prevent fish fry from leaking out from the gap between the tray and the inner box when the tray is lifted.

[0011] As a further preferred embodiment of this utility model, the hoisting mechanism further includes two hoisting rods, each with a sliding groove inside. One end of each hoisting rod is rotatably connected to a corresponding first bearing seat. A connecting rod is also provided between the two hoisting rods. Both ends of the connecting rod have connecting grooves, which are rotatably connected to the corresponding hoisting rods. A second bearing seat is rotatably connected to the middle of the connecting rod. A fixed seat is fixedly installed on the second bearing seat. The fixed seat is fixedly installed at one end of the cylinder piston rod. By connecting the tray with the first bearing seat and the cylinder piston rod through the hoisting mechanism, when one end of the tray abuts against the lower end of the limiting block after being lifted, the tray can tilt towards the limiting block, thereby facilitating the fish fry to approach the fry collector's side using gravity.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a cylinder is installed on the top cover, and an inner box is installed inside the outer box. A tray is installed inside the inner box, so that the tray is movably connected to the piston rod of the cylinder through a lifting mechanism. This allows the hatched fish fry to be quickly lifted from the inner box and the angle to be changed in conjunction with the limiting block on the inside of the inner box, so that the fish fry can accumulate on one side of the tray and be easily removed by personnel.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-4 As shown, the present invention provides a fish fry hatching device for aquaculture, comprising an outer casing 1, a top cover 2 fixedly installed on the outer casing 1, an operation port 3 opened inside the top cover 2, a main controller 4 fixedly installed on the rear side of the outer casing 1, a circulation pump 5 fixedly installed on the top cover 2 near the operation port 3, the circulation pump 5 being electrically connected to the port of the main controller 4 via a connecting wire, an oxygenation pipe 6 fixedly installed at the lower end of the top cover 2 near the circulation pump 5, and one end of the oxygenation pipe 6 being connected to the output end of the oxygenation equipment inside the main controller 4 via a pipe, a frame 7 fixedly installed on the top cover 2, a cylinder 8 fixedly installed on the frame 7, the cylinder 8 being connected to the air pump inside the main controller 4 via a connecting pipe, an inner casing 9 fixedly installed inside the outer casing 1, a tray 10 inserted inside the inner casing 9, a plurality of first shaft seats 11 fixedly installed at the bottom inside the tray 10, and the first shaft seats 11 being movably connected to one end of the piston rod of the cylinder 8 via a hoisting mechanism 12.

[0021] like Figure 2As shown, a drain pipe 13 is fixedly installed inside the inner box 9, and a drain pipe 13 is also fixedly installed inside the outer box 1. A limit block 23 is also fixedly installed on the upper side of one side of the inner box 9. The limit block 23 on one side of the inner box 9 can limit one end of the tray 10 raised inside the inner box 9, thereby providing conditions for changing the angle of the tray 10. Overflow ports 14 are opened on the front and rear sides of the inner box 9. A filter screen is fixedly installed inside the overflow port 14. The opening of the overflow port 14 can control the highest water level inside the inner box 9, and facilitate the rapid discharge of water located above the tray 10 in the inner box 9 when the tray 10 is raised.

[0022] like Figures 2-4 As shown, a water vent 15 is provided at the bottom of the tray 10, and a filter screen is fixedly installed inside the water vent 15. The tray 10 can lift the hatched fish fry from the inner box 9 to a position near the operation port 3, making it easier for personnel to remove the fish fry. At the same time, the water vent 15 can facilitate the rapid discharge of water in the inner box 9 above the tray 10 when the tray 10 is lifted, in conjunction with the overflow port 14. A rubber pad 16 is fixedly installed on the top of the tray 10 along its contour, and the top of the rubber pad 16 has a sloping structure and abuts against the inside of the inner box 9. The rubber pad 16 can prevent fish fry from leaking out from the gap between the tray 10 and the inner box 9 when the tray 10 is lifted. The lifting mechanism 12 also includes two lifting rods 17, and the lifting rods 17 have grooves inside. 18. One end of the lifting rod 17 is rotatably connected to the corresponding first bearing 11. A connecting rod 19 is also provided between the two lifting rods 17. Both ends of the connecting rod 19 are provided with connecting grooves 20. The connecting grooves 20 are rotatably connected to the corresponding lifting rods 17. The middle of the connecting rod 19 is rotatably connected to the second bearing 21. A fixed seat 22 is fixedly installed on the second bearing 21. The fixed seat 22 is fixedly installed on one end of the piston rod of the cylinder 8. The tray 10 is connected to the piston rod of the cylinder 8 through the lifting mechanism 12 in conjunction with the first bearing 11. When the tray 10 is lifted, one end of it touches the lower end of the limiting block 23, so that the tray 10 can tilt towards the limiting block 23, thereby making it easier for the fish fry to approach the side of the fry collector by gravity.

[0023] It should be noted that this utility model is a fish fry hatching device for aquaculture. First, the fish eggs are placed on the tray 10 in the inner box 9. After the device is started, the main controller 4 controls the circulation pump 5 and the oxygenation equipment to work. The circulation pump 5 oxygenates the water through the oxygenation pipe 6 to ensure that the dissolved oxygen in the water is sufficient to meet the hatching requirements of the fish eggs. At the same time, the circulation pump 5 makes the water circulate and simulates the natural water flow environment to create good conditions for the hatching of fish eggs.

[0024] After the fish eggs hatch into fry, when it is necessary to remove the fry, the main controller 4 controls the air pump to supply air to the cylinder 8. The piston rod of the cylinder 8 extends and drives the tray 10 to rise through the hoisting mechanism 12. One end of the hoisting rod 17 is rotatably connected to the first shaft seat 11 at the bottom of the tray 10. The connecting grooves 20 at both ends of the connecting rod 19 are rotatably connected to the hoisting rod 17, so the tray 10 can be gradually lifted from the inner box 9 and close to the operating port 3. At this time, the overflow port 14 on the front and rear sides of the inner box 9 and the water inlet 15 at the bottom of the tray 10 can quickly drain the water above the tray 10 during the lifting process. When the tray 10 rises to the point where one end touches the limit stop 23, due to the movable connection between the tray 10 and the hoisting mechanism 12, the tray 10 will tilt towards the limit stop 23. Then, the fry will accumulate on the lower side of the tray 10 under the action of gravity. The operator can easily remove the fry through the operating port 3 on the top cover 2.
