Description

Technical Field

[0001] The utility model relates to the field of fry breeding, in particular to a breeding device for aquatic fry. Background Art

[0002] Aquaculture is an agricultural activity that cultivates and raises various aquatic organisms through artificial means to meet people's demand for aquatic products. Fry are young fish hatched not long ago. When breeding, a breeding box is needed for raising. During the growth process of fry, a large amount of feeding is required. The traditional feeding position of feed is single, and fry are prone to gather at the feeding point to scramble, resulting in some fry eating more feed and some fry eating less feed, with poor feeding effect. Moreover, fry are also prone to being injured during the scramble. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a breeding device for aquatic fry.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A breeding device for aquatic fry, including a breeding box and a feed bin. A feeding device is installed on the top of the breeding box. The feeding device includes a fixing frame, a moving device and a feeding hopper. The moving device includes a threaded rod, a driving motor and a moving table. The threaded rod is rotatably connected to the fixing frame. One end of the threaded rod is connected to the output end of the driving motor. The threaded rod is threadedly connected to the moving table. Limiting rods are arranged on both sides of the fixing frame. Limiting openings are arranged on both sides of the moving table. The limiting rods pass through the limiting openings. The feeding hopper is installed on the moving table. A feeding port is arranged on the moving table below the feeding hopper. A feeding pipe is arranged at the bottom of the feed bin, and the end of the feeding pipe is located directly above the feeding hopper.

[0005] Further, there are two feeding hoppers, which are respectively arranged on both sides of the moving table.

[0006] Further, a feeding amount control device is arranged on the feeding port. The feeding amount control device includes a fixed baffle and a rotating plate.

[0007] Further, a feeding notch is arranged on one side of the fixed baffle. The rotating plate is rotatably connected to the fixed baffle. An arc-shaped discharging port is arranged on the rotating plate. A dialing groove is arranged on one side of the bottom of the feeding hopper. A dialing rod is arranged on the rotating plate and passes through the dialing groove.

[0008] Further, feeding amount indication marks are arranged on the surface of the feeding hopper above the dialing groove.

[0009] Further, a solenoid valve is arranged at the top of the feeding pipe, and a travel switch is arranged on the fixing frame.

[0010] The beneficial effects of the present utility model are as follows: By providing a moving device, the feeding hopper can be moved during feeding, thus avoiding the situation where the feeding position is single, resulting in fry competing for feed and getting injured. In addition, according to the growth status of the fry and the number of fry in the breeding tank, the feeding amount control device can control the feeding amount for one movement of the feeding hopper to meet the needs of fry breeding.

Detailed Embodiment

[0016] Embodiment: The present utility model will be further described below with reference to the drawings.

[0017] An aquaculture device for aquatic fry, comprising a culture tank 1 and a feed bin 5. A feeding device is installed on the top of the culture tank 1. The feeding device includes a fixed frame 2, a moving device and a feeding hopper 4. The moving device includes a threaded rod 31, a driving motor 6 and a moving platform 3. The threaded rod 3 is rotatably connected to the fixed frame 2. One end of the threaded rod 31 is connected to the output end of the driving motor 6. The threaded rod 31 is threadedly connected to the moving platform 3. Limiting rods 32 are arranged on both sides of the fixed frame 2. Limiting openings are arranged on both sides of the moving platform 3. The limiting rods 32 pass through the limiting openings. The feeding hopper 4 is installed on the moving platform 3. A feeding port is arranged on the moving platform 3 below the feeding hopper 4. A feeding pipe 9 is arranged below the feeding port. A feeding pipe 51 is arranged at the bottom of the feed bin 5. The end of the feeding pipe 51 is arranged directly above the feeding hopper 4. When there is less feed in the feeding hopper 4, the staff can open the valve between the feed bin 5 and the feeding pipe 51, send the feed in the feed bin 5 into the feeding hopper 4 through the feeding pipe 51, and discharge it into the culture tank 1 through the feeding pipe 9 below the feeding hopper 4 during feeding. When feeding is required, the driving motor 6 is started, and the threaded rod 31 rotates to drive the moving platform 3 to move in the opposite direction, so as to drive the feeding hopper 4 on the moving platform 3 to move for feeding, avoiding a single feeding position that leads to fry competing for feed, reducing the probability of fry injury and improving the feeding effect.

[0018] Further, there are two feeding hoppers 4, which are respectively arranged on both sides of the moving platform 3, so that the feed is more evenly distributed, and feeding is carried out at two positions at the same time, further avoiding the fry from scrambling when starting to feed.

[0019] Further, a feeding amount control device is arranged on the feeding port. The feeding amount control device includes a fixed baffle 82 and a rotating piece 81. When feeding, the feeding amount control device can control the amount of feed discharged when the moving platform 3 moves once, so as to control the feeding amount according to the specific situation of the fry in the culture tank 1.

[0020] Further, a feeding notch 821 is arranged on one side of the fixed baffle 82. The rotating piece 81 is rotatably connected to the fixed baffle 82. An arc-shaped discharge port 812 is arranged on the rotating piece 81. A dial groove 41 is arranged on one side of the bottom of the feeding hopper 4. A dial rod 811 is arranged on the rotating piece 81 and passes through the dial groove 41. The feed falls into the feeding pipe 9 from the overlapping part of the discharge port 812 and the feeding notch 821. By rotating the rotating piece 81 with the dial rod 811, the overlapping area of the discharge port 812 and the feeding notch 821 can be controlled, and thus the feeding amount can be controlled.

[0021] Further, a feeding amount indication mark 42 is arranged on the surface of the feeding hopper 4 above the dial groove 41 to assist the user in adjusting the feeding amount according to the specific situation of the fry in the culture tank 1.

[0022] Further, a solenoid valve 91 is provided at the top of the feeding pipe 9, and travel switches 7 are respectively provided on the fixing frames 2 on both sides of the breeding tank 1. When the moving platform 3 moves to contact the travel switch 7, the driving motor 6 and the solenoid valve 91 are closed, and the staff can turn on the driving motor 6 and the solenoid valve 91 through the control panel or the controller.

[0023] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
