Description

Technical Field

[0001] This application relates to the field of aquaculture technology, and in particular to aquaculture feeding devices. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process from seedling to marketable aquatic products under artificial feeding and management. In aquaculture, feed is required to supply the farmed aquatic animals. Feeding is the most important aspect of aquatic animal husbandry; therefore, the amount of feed should be increased as much as possible. The basic requirements for feeding are even distribution, sufficient quantity, and quality. The fish should never be allowed to alternate between being full and hungry; therefore, feeding should be done regularly and in measured quantities.

[0003] Existing aquaculture feeding devices typically employ continuous feeding or manual valve control, failing to achieve periodic intermittent feeding. This often leads to overfeeding or inconsistent feeding rates, resulting in feed waste and failing to match the aquatic animals' feeding habits in batches, thus affecting feed utilization. Furthermore, single-shaft agitation or simple blade rotation is insufficient to break up feed sedimentation and stratification within the tank, especially for mixed feeds of different particle sizes and densities, easily causing particle-to-powder separation and even localized clumping that blocks the feeding inlet, requiring frequent manual cleaning. Therefore, this aquaculture feeding device is proposed to address these issues. Summary of the Invention

[0004] This embodiment addresses the problems of unstable feeding, feed waste, low utilization rate, easy stratification and clumping, and blockage of the feed inlet caused by the use of continuous feeding or manual valve control and a single stirring method in the aquaculture feeding device.

[0005] According to one aspect of this application, an aquaculture feeding device is provided, comprising a mounting plate on which a housing is fixedly mounted, and a fixing plate fixedly mounted on the housing. Two reset components are provided on the fixing plate, each including a baffle, a coil spring, a push plate, and a fixing ring. Two rotating rods are rotatably connected to the fixing plate via bearings. Fixing rings are fixedly mounted at the positions of the two rotating rods on the fixing plate. A coil spring is disposed inside each of the two fixing rings, and both ends of the coil springs are fixedly connected to the fixing rings and the rotating rods, respectively. A connecting plate is fixedly mounted at the bottom end of each rotating rod.

[0006] A baffle is fixedly installed at one end of the connecting plate.

[0007] In this technical solution, a motor is fixedly installed on the box body, and a second rotating shaft and two first rotating shafts are rotatably connected inside the box body through bearings. The output shaft of the motor extends into the box body and is fixedly connected to one end of the second rotating shaft. Multiple stirring blades are provided on the second rotating shaft and the two first rotating shafts.

[0008] In this technical solution, a protective shell is fixedly installed on the inner wall of the box. The second rotating shaft is located inside the protective shell and is fitted with two main pulleys. Both of the first rotating shafts are located inside the protective shell and are fitted with slave pulleys. Both main pulleys are connected to the slave pulleys via belts.

[0009] In this technical solution, a guide platform is provided inside the box, and two guide grooves are opened inside the guide platform.

[0010] In this technical solution, two discharge ports are provided on the bottom wall of the box, and the box is connected to the two discharge ports through a guide groove. Both baffles can be located below the discharge ports.

[0011] In this technical solution, one end of each of the two first rotating shafts extends into the interior of the guide trough and is provided with spiral blades.

[0012] In this technical solution, the second rotating shaft passes through the box body and extends to the outer end of the box body where a push plate is fixedly installed. The push plate can abut against two baffles. In this technical solution, a spreading disc is fixedly installed at the outer end of the second rotating shaft located in the box body.

[0013] In this technical solution, a feed pipe is connected to the box body, and a threaded cap is threadedly connected to the feed pipe.

[0014] In this technical solution, the floating plate is provided with four support legs, and the top ends of the four support legs are fixedly installed to the same mounting plate.

[0015] Through the above embodiments of this application, by setting a reset component and starting the motor, the feed inlet can be opened and closed periodically. By controlling the rotation speed of the second rotating shaft, the feeding frequency can be adjusted. The opening time of the baffle is relatively fixed each time, so that the amount of feed fed each time tends to be stable, avoiding waste caused by excessive feed being fed at one time, and also meeting the needs of aquatic animals to eat in batches, improving feed utilization. When the push plate leaves the baffle position, the coil spring drives the baffle to reset and block the feed inlet, which can prevent feed from continuously flowing out, avoid feed leakage due to accidental factors when feeding is not needed, reduce feed residue in the aquaculture water, reduce the risk of water pollution, and help maintain a good aquaculture water environment.

[0016] By working in concert with the second rotating shaft and the two first rotating shafts, the feed at the bottom of the box is transported to the middle when the spiral blades rotate in the forward direction. This breaks up the stratification caused by feed sedimentation and allows feeds of different compositions and particle sizes to form a three-dimensional circulation within the box. Compared with a single stirring method, this method can mix the feed more thoroughly, ensuring that the feed is nutritionally balanced each time it is fed. It also prevents the feed from accumulating and clumping at the feed trough and discharge port, keeping the discharge channel unobstructed, ensuring the continuity of the feeding process, and reducing the frequency of manual cleaning and maintenance.

[0017] By setting up a feeding disc, when the feed falls from the feed inlet onto the feeding disc, the second rotating shaft drives the feeding disc to rotate, and the feed is evenly scattered in all directions by centrifugal force, covering a large area and avoiding feed accumulation in local areas, so that aquatic animals in all locations of the aquaculture water can feed.

[0029] Please refer to Figures 1-4. The aquaculture feeding device includes a mounting plate 12 and a float 25. A box 1 is fixedly mounted on the mounting plate 12, and a fixing plate 22 is fixedly mounted on the box 1. The fixing plate 22 is provided with two reset components. The reset components include a baffle 21, a coil spring 19, a push plate 17, and a fixing ring 14. Two rotating rods 15 are rotatably connected to the fixing plate 22 via bearings. Fixing rings 14 are fixedly mounted on the fixing plate 22 at the positions of the two rotating rods 15. A coil spring 19 is provided inside each of the two fixing rings 14. The two ends of the two coil springs 19 are fixedly connected to the fixing rings 14 and the rotating rods 15, respectively. A connecting plate 20 is fixedly mounted on the bottom end of the rotating rods 15, and a baffle 21 is fixedly mounted on one end of the connecting plate 20.

[0030] In this technical solution, a motor 6 is fixedly installed on the box 1. The inside of the box 1 is rotatably connected to a second rotating shaft 9 and two first rotating shafts 3 via bearings. The output shaft of the motor 6 extends into the inside of the box 1 and is fixedly connected to one end of the second rotating shaft 9. Multiple stirring blades 2 are provided on the second rotating shaft 9 and the two first rotating shafts 3 at equal intervals.

[0031] In this technical solution, a protective shell 11 is fixedly installed on the inner wall of the housing 1. The second rotating shaft 9 is located inside the protective shell 11 and is fitted with two main pulleys 5. The two first rotating shafts 3 are located inside the protective shell 11 and are fitted with driven pulleys 10. The two main pulleys 5 are connected to the driven pulleys 10 through belts 4.

[0032] In this technical solution, a guide platform 23 is provided inside the box 1, and two guide grooves are opened inside the guide platform 23.

[0033] In this technical solution, two discharge ports 18 are provided on the bottom wall of the box body 1. The box body 1 is connected to the two discharge ports 18 through a guide groove. Both baffles 21 can be located below the discharge ports 18.

[0034] In this technical solution, one end of each of the two first rotating shafts 3 extends into the interior of the guide groove and is provided with a spiral blade 16.

[0035] In this technical solution, the second rotating shaft 9 passes through the housing 1 and extends to the outer end of the housing 1 where a push plate 17 is fixedly installed. The push plate 17 can abut against the two baffles 21.

[0036] In this technical solution, the second rotating shaft 9 is fixedly installed with a spreading disc 24 at the outer end of the housing 1.

[0037] In this technical solution, the housing 1 is connected to a feed pipe 8, and the feed pipe 8 is threadedly connected to a threaded cap 7.

[0038] In this technical solution, the floating plate 25 is provided with four support legs 13, and the top ends of the four support legs 13 are fixedly installed to the same mounting plate 12.

[0039] In use, all electrical components described herein are externally connected to a power supply and control switch. Starting the motor 6 causes its output shaft to rotate, driving the second shaft 9. The second shaft 9, through two main pulleys 5, drives the driven pulleys 10, causing the two first shafts 3 to rotate. Both the second shaft 9 and the two first shafts 3 drive multiple stirring blades 2 to stir the feed. This ensures the feed is subjected to multi-directional forces during stirring, resulting in more uniform mixing of feed ingredients of different particle sizes and densities, preventing clumping or stratification. The simultaneous operation of multiple stirring blades 2 increases the contact area with the feed, improving stirring efficiency and shortening the time required for uniform mixing. It also enhances the dispersion ability of viscous or easily agglomerated feed, keeping it loose and preventing blockages during feeding, ensuring a smooth feeding process.

[0040] The second rotating shaft 9 and the two first rotating shafts 3 work together, cooperating with the spiral blades 16 to move the housing in the forward direction.

[0041] 1. The feed at the bottom is conveyed to the middle, breaking up the stratification caused by feed sedimentation. This allows feeds of different compositions and particle sizes to form a three-dimensional circulation within the box 1. Compared to a single stirring method, this can mix the feed more thoroughly, ensuring nutritional balance in each feeding. It also prevents feed from accumulating and clumping at the feed trough and discharge port 18, keeping the feeding channel unobstructed, ensuring the continuity of the feeding process, and reducing the frequency of manual cleaning and maintenance.

[0042] Simultaneously, the second rotating shaft 9 drives the push plate 17 and the feeding disc 24 to rotate, causing the push plate 7 to push one of the baffles 21 to move to one side. At this time, the feeding port 18 is unobstructed, and feed is fed through the feeding port 18. When the push plate 17 rotates to another direction, with the cooperation of the coil spring 19, the rotating rod 15 drives the baffle 21 to reset through the connecting plate 20, and re-obstructs the feeding port 18. The feeding port 18 can be opened and closed periodically. By controlling the rotation speed of the second rotating shaft 9, the feeding frequency can be adjusted. The opening time of the baffle 21 is relatively fixed each time, so that the amount of feed fed each time tends to be stable, avoiding waste caused by excessive feed being fed at one time, and also meeting the needs of aquatic animals to eat in batches, thus improving feed utilization. When the push plate 17 leaves the position of the baffle 21, the coil spring 19 drives the baffle 21 to move. Resetting the feed outlet 18 can prevent feed from continuously flowing out, avoid feed leakage due to accidental factors when feeding is not needed, reduce feed residue in the aquaculture water, reduce the risk of water pollution, and help maintain a good aquaculture water environment.

[0043] When the feed falls from the feed inlet 18 to the feed spreading plate 24, the second rotating shaft 9 drives the feed spreading plate 24 to rotate, and the feed is evenly scattered in all directions by centrifugal force, covering a large area and avoiding the accumulation of feed in local areas, so as to ensure that aquatic animals in all locations in the aquaculture water can feed.

[0044] The advantages of this application are:

[0045] 1. By setting a reset component and starting the motor 6, the feed inlet 18 can be opened and closed periodically. The feeding frequency can be adjusted by controlling the rotation speed of the second rotating shaft 9. The baffle 21 opens for a relatively fixed time each time, so that the amount of feed fed each time tends to be stable, avoiding waste caused by excessive feed being fed at one time. It can also meet the needs of aquatic animals to eat in batches and improve feed utilization. When the push plate leaves the position of the baffle 21, the coil spring 19 drives the baffle 21 to reset and block the feed inlet 18, which can prevent feed from continuously flowing out. This avoids feed leakage due to accidental factors when feeding is not needed, reduces feed residue in the aquaculture water, reduces the risk of water pollution, and helps maintain a good aquaculture water environment.

[0046] 2. Through the coordinated operation of the second rotating shaft 9 and the two first rotating shafts 3, and in conjunction with the forward rotation of the spiral blades 16, the feed at the bottom of the box 1 is transported to the middle, breaking the stratification caused by feed sedimentation. This allows feeds of different compositions and particle sizes to form a three-dimensional circulation within the box 1. Compared with a single stirring method, this method can mix the feed more thoroughly, ensuring nutritional balance in each feeding. It also prevents feed from accumulating and clumping at the feed guide trough and discharge port 18, keeping the feeding channel unobstructed, ensuring the continuity of the feeding process, and reducing the frequency of manual cleaning and maintenance.

[0047] 3. By setting up a feeding tray 24, when the feed falls from the feed inlet 18 to the feeding tray 14, the second rotating shaft 9 drives the feeding tray 14 to rotate. The feed is evenly scattered in all directions by centrifugal force, covering a large area and avoiding feed accumulation in local areas, ensuring that aquatic animals in all locations in the aquaculture water can feed.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
