Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to a feeding device for ecological fish farming. Background Art

[0002] Ecological fish farming is a farming model based on ecological principles and using system engineering methods to coordinate fish farming with the ecological environment to achieve efficient resource utilization and sustainable development. The principle of ecological fish farming is to simulate the natural ecosystem and build a relatively stable ecological community by rationally matching different types of aquatic organisms, so that materials and energy can be recycled within the system, reducing dependence on and pollution of the external environment.

[0003] In the prior art, during the aquaculture process, it is necessary to feed fish feed into the fish pond regularly, and most of the time, manual feeding is used for feeding, which increases the labor intensity of the breeders and is prone to uneven feeding and difficulty in controlling the feeding amount. Some feed the fish pond through a feeding device, but most of the feeding devices feed at a fixed point, which will cause the fish to concentrate in one place, so that some fish can eat and some fish cannot. In addition, the feeding device is prone to blockage when in use, thereby affecting the feeding efficiency of the feed and bringing inconvenience to the breeders. For this reason, we propose a feeding device for ecological fish farming. Summary of the invention

The indicating rod rotates with the rotating shaft. When the indicating rod points vertically upward, the feeding hole on the rotating cylinder is aligned with the rectangular through hole, and at this time, the feed in the storage bin enters the rotating cylinder, facilitating more convenient operation for the staff.

[0027] 3. By pushing the blocking rod to one side, the blocking rod is disengaged from the clamping groove, and then the lid is opened, facilitating the staff to pour feed into the storage bin. The lid is conveniently limited by the blocking rod and the clamping seat. The counterweights maintain the stability of the floating cylinder when floating.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1

[0037] Please refer to Figures 1-6 , a feeding device for ecological fish farming shown in the figure, including:

[0038] Two buoys 1 and a U-shaped mounting plate 2 fixed between the two buoys 1;

[0039] It further includes:

[0040] Fixing brackets 3, there are two fixing brackets 3 and they are symmetrically fixed on the top surface of the U-shaped mounting plate 2. An installation box 4 is fixed between the two fixing brackets 3. Two support rods 5 are fixed on both sides of the installation box 4.

[0041] L-shaped fixing rods 8, there are two L-shaped fixing rods 8 and they are fixed on one side of the U-shaped mounting plate 2. A walking component is arranged between the two L-shaped fixing rods 8 and is used for the movement of the device. A quantitative feeding component is arranged inside the installation box 4. An anti-blocking component matching the quantitative feeding component is arranged at the bottom of the installation box 4, and the anti-blocking component improves the smoothness of feeding.

[0042] Further as Figure 2 、 Figure 3 and Figure 5 shown, specifically, the quantitative feeding component includes:

[0043] A rotating cylinder 9, the rotating cylinder 9 is rotatably installed inside the installation box 4. A feeding hole 10 matching the rectangular through hole 6 is opened on the surface of the rotating cylinder 9. A driving motor 11 coaxially connected to the rotating cylinder 9 is fixedly installed on the outer surface of the installation box 4. A discharge hole 12 is opened on the bottom surface of the installation box 4 corresponding to the feeding hole 10. A stirring component matching the rotating cylinder 9 is arranged inside the storage box 7;

[0044] A rectangular corrugated pipe 13, the rectangular corrugated pipe 13 is fixed at the bottom of the installation box 4 and is communicated with the discharge hole 12. An L-shaped discharge pipe 14 is fixed at the bottom of the rectangular corrugated pipe 13. A connection hole 15 is opened on the top surface of the U-shaped mounting plate 2, and the L-shaped discharge pipe 14 penetrates through the connection hole 15.

[0045] It should be noted that the driving motor 11 drives the rotating cylinder 9 to rotate inside the installation box 4, so that the feeding hole 10 is aligned with the rectangular through hole 6, and thus the feed in the storage box 7 enters the rotating cylinder 9. When the rotating cylinder 9 is full, the feeding stops, and then the rotating cylinder 9 continues to rotate. When the rotating cylinder 9 rotates to the discharge hole 12, the feed is discharged from the feeding hole 10 and then discharged along the rectangular corrugated pipe 13 and the L-shaped discharge pipe 14.

A plurality of springs 19 are fixed on both sides of the L-shaped discharge pipe 14, and the ends of the springs 19 are fixed to the hole wall of the connection hole 15.

[0048] It should be noted that the floating bottle 18 on the anti-blocking component floats with the fluctuation of the water surface, thereby driving the shaking of the L-shaped discharge pipe 14, so as to prevent the feed from being blocked during the discharging process.

[0049] Furthermore, as Figure 2 and Figure 4 shown, specifically, the walking component includes:

[0050] Limit cylinders 20, there are two limit cylinders 20 which are respectively fixed at the ends of the L-shaped fixing rods 8. A connecting shaft 21 is rotatably connected inside the two limit cylinders 20. Three impellers 22 are evenly fixed on the outer surface of the connecting shaft 21. The middle impeller 22 corresponds to the floating bottle 18. A waterproof motor 23 is fixed on one side of one of the L-shaped fixing rods 8. A first gear 24 is fixed at the output end of the waterproof motor 23. A second gear 25 is fixedly sleeved on the outer surface of the connecting shaft 21. The first gear 24 and the second gear 25 are in meshing transmission.

[0051] It should be noted that the waterproof motor 23 drives the first gear 24 to rotate, thereby driving the second gear 25 to rotate, so that the connecting shaft 21 rotates in the two limit cylinders 20, and then drives the impellers 22 to rotate. The impellers 22 rotating in the water drive the floating cylinder 1 to move on the water surface; in addition, a storage battery is fixedly installed on one side of the installation box 4, and the drive motor 11 and the waterproof motor 23 are electrically connected to the storage battery, so as to supply power to the drive motor 11 and the waterproof motor 23.

[0052] Furthermore, as Figure 1 and Figure 4 shown, specifically, a connecting rod 26 is fixed on the bottom surface of one of the L-shaped fixing rods 8.

Two fixing bolts 29 are threadedly penetrated through one side of the second protective frame 28. The ends of the fixing bolts 29 are threadedly connected to one side of the first protective frame 27. The first protective frame 27 and the second protective frame 28 are located outside the first gear 24 and the second gear 25.

[0053] It should be noted that the first gear 24 and the second gear 25 are held by the first protective frame 27 and the second protective frame 28, avoiding damage to the first gear 24 and the second gear 25 caused by impurities entering the teeth; the first protective frame 27 and the second protective frame 28 are connected by the fixing bolts 29, which is convenient for the installation between the first protective frame 27 and the second protective frame 28. A sealing glue can also be applied to the contact surface between the first protective frame 27 and the second protective frame 28, so as to further improve the sealing performance after the docking of the first protective frame 27 and the second protective frame 28.

[0054] Embodiment 2

[0055] On the basis of the first embodiment, according to Figure 1 and Figure 6 shown, it is worth specifically stating that the stirring assembly includes:

[0056] The stirring rod 30 is rotatably installed on the inner wall of the storage bin 7. A rotating shaft 31 coaxially connected to the rotating cylinder 9 is rotatably connected to the side of the installation box 4 away from the driving motor 11. Transmission wheels 32 are fixed on the end of the stirring rod 30 and the outer surface of the rotating shaft 31, and a belt 33 is rotatably sleeved between the two transmission wheels 32.

[0057] It is worth stating that when the rotating cylinder 9 rotates, it drives the rotating shaft 31 to rotate, thereby driving the stirring rod 30 to rotate in the storage bin 7 through the transmission wheels 32 and the belt 33, so as to stir the feed in the storage bin 7, avoid the feed from sticking in the storage bin 7, and prevent the storage bin 7 from being blocked when discharging.

[0058] Furthermore, as Figure 6 shown, it is worth specifically stating that an indicating rod 34 is fixed at the end of the rotating shaft 31. The indicating rod 34 rotates with the rotating shaft 31. When the indicating rod 34 points vertically upward, the feed inlet hole 10 on the rotating cylinder 9 is aligned with the rectangular through hole 6. At this time, the feed in the storage bin 7 enters the rotating cylinder 9, which is convenient for the staff to operate more conveniently; An observation window 35 is fixed on one side of the storage bin 7, and it is convenient to check the amount of feed in the storage bin 7 through the observation window 35, so that the staff can add it in time.

[0059] Furthermore, as Figure 2 and Figure 6 shown, it is worth specifically stating that one side of the top surface of the storage bin 7 is hinged with a box cover 36. One side of the box cover 36 is rotatably connected with a blocking rod 37. A card seat 38 is fixed on the outer surface of the storage bin 7, and a card slot 39 is opened on the side of the card seat 38 corresponding to the blocking rod 37.

[0060] It is worth stating that by pushing the blocking rod 37 to one side, the blocking rod 37 is disengaged from the card slot 39, and then the box cover 36 is opened, so as to facilitate the staff to pour the feed into the storage bin 7. The box cover 36 is conveniently limited by the blocking rod 37 and the card seat 38.

[0061] Furthermore, as Figure 1 and Figure 2 shown, it is worth specifically stating that connecting plates 40 are fixed on both sides of the U-shaped mounting plate 2. A counterweight 41 is fixed at the bottom of the connecting plate 40 to maintain the stability of the floating cylinder 1 when floating; A U-shaped pull rod 42 is fixed on the other side of the U-shaped mounting plate 2. A connecting rope 43 is fixed in the middle of the outer surface of the U-shaped pull rod 42. The floating cylinder 1 is pulled by the connecting rope 43 and the U-shaped pull rod 42 to prevent the device from being blown away in strong winds, and it is also convenient to pull the device back after the feeding is completed.

[0062] This embodiment also has the following working process: The feeding device is lifted in the water by two buoyancy cylinders 1, so that the feeding device can move on the water surface. The staff pours the feed into the storage bin 7, and then starts the waterproof motor 23, so that the waterproof motor 23 drives the first gear 24 to rotate, thereby driving the second gear 25 to rotate, so that the connecting shaft 21 rotates in the two limit cylinders 20, and then drives the impeller 22 to rotate. The impeller 22 rotating in the water drives the buoyancy cylinder 1 to move on the water surface. During the movement, by starting the driving motor 11, the driving motor 11 drives the rotating cylinder 9 to rotate in the mounting box 4, so that the feed inlet 10 is aligned with the rectangular through hole 6, and thus the feed in the storage bin 7 enters the rotating cylinder 9. When the rotating cylinder 9 is full, the feeding automatically stops, and then the rotating cylinder 9 continues to rotate. When the rotating cylinder 9 rotates to the discharge hole 12, the feed is discharged from the feed inlet 10 and discharged along the rectangular corrugated pipe 13 and the L-shaped discharge pipe 14, so as to carry out feeding while moving. During the movement, the floating bottle 18 fluctuates due to the water surface undulation, so that the L-shaped discharge pipe 14 below the rectangular corrugated pipe 13 is driven by the extension rod 16 to shake under the action of the spring 19, thereby keeping the feed discharging smooth and avoiding blockage. And the impeller 22 in the middle will drive the water surface around the impeller 22 to fluctuate when driven, thereby further improving the undulation effect of the floating bottle 18, and further improving the anti-blocking effect. At the same time, the feeding device can move to the feeding position for fixed-point feeding, improving the feeding convenience; when the rotating cylinder 9 rotates, it drives the rotating shaft 31 to rotate, and thus drives the stirring rod 30 to rotate in the storage bin 7 through the transmission wheel 32 and the belt 33, so as to stir the feed in the storage bin 7 and avoid the feed from sticking in the storage bin 7, thereby preventing blockage when the storage bin 7 discharges materials.

[0063] The driving motor 11 and the waterproof motor 23 can be purchased on the market and are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
