Description

Technical Field

[0001] The invention belongs to the technical field of deep-sea aquaculture of large yellow croaker, and specifically relates to a feed feeding device for deep-sea aquaculture of large yellow croaker. Background Art

[0002] Deep-sea aquaculture refers to marine aquaculture carried out in waters far from the coast, usually in areas with deep water and strong currents. Unlike offshore aquaculture, deep-sea aquaculture avoids pollution sources, has cleaner water quality, and a more natural aquaculture environment. It can effectively reduce the risk of aquaculture diseases and greatly improve the economic benefits of aquaculture. Large yellow croaker is a local marine fish unique to my country and an important species suitable for the development of deep-sea aquaculture.

[0003] Deep-sea yellow croaker farming requires regular feeding. Existing feed feeding machines mostly feed at a certain point in the deep-sea farming cages, resulting in the feed being too concentrated in one place. Deep-sea farming cages are generally large, and there are more yellow croakers inside. When feeding at a fixed point, some yellow croakers will gather at the feeding point, which makes it difficult for subsequent yellow croakers to eat, resulting in uneven individual yellow croakers in the same deep-sea farming cage, which seriously affects the economic benefits of yellow croaker farming.

[0004] To this end, the present invention provides a feed feeding device for deep-sea aquaculture of large yellow croaker. Summary of the invention

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. A feeding device for deep-sea breeding of large yellow croakers according to the present invention, by starting the first servo motor of the bottom plate, the first screw rod on the first servo motor moves vertically with the first base and the second servo motor. At the same time, the second servo motor is started, so that the second screw rod on the second servo motor moves horizontally with the storage box on the second base. Then the pump in the storage box is started to extract the feed and discharge it through the discharge pipe. By using the uniform and slow movement in the horizontal and vertical directions, the feed falling into the breeding net can be effectively dispersed in various positions, effectively avoiding the excessive concentration of the scattered feed in a certain place. Thereby effectively solving the problem that after the fish school is over-concentrated during feeding, the inner fish school over-eats, and the outer fish school is difficult to approach, resulting in the large yellow croaker seedlings in the same breeding net having different feeding amounts and large differences in body size. The slider installed at the same time can assist in supporting the second screw rod and cooperate with the second screw rod to slide in the rectangular groove of the support block. At the same time, the sliding slider can also use the triangular top plate to clean the rectangular groove, reduce impurities in the rectangular groove, and ensure that the slider slides normally in the rectangular groove of the support block.

[0017] 2. The feed feeding device for deep-sea breeding of large yellow croaker of the present invention can effectively guide part of the feed to the surroundings through the installed guide column when the feed flows out through the discharge pipe, while the other part of the feed falls directly through the holes on the guide column. The designed guide column can make part of the feed fall to the bottom while the other part of the feed falls to the surroundings, so as to feed the large yellow croaker seedlings on the periphery, and play the role of more uniform feeding of the feed. At the same time, the installed filter can effectively reduce the impurities entering the discharge pipe while ensuring that the feed can pass.

[0018] 3. The feed feeding device for deep-sea breeding of large yellow croaker described in the present invention uses the output end of the electric push rod to slide the adjustment plate in the direction away from the discharge pipe, so that there is a gap between the adjustment plate and the inner wall of the discharge pipe, so that the feed can flow out through the discharge pipe. In this way, the flow rate of the discharge pipe can be adjusted in real time. At the same time, the end cover rotates and resets under the action of the torsion spring, thereby closing the side of the discharge pipe to prevent the feed from leaking from the side. When the electric push rod moves, it carries the sleeve plate, the fixed plate, the stirring plate, the guide plate and the cone rod and moves with it, and uses the stirring plate, the guide plate and the cone rod to stir the feed stored for a long time in the storage box. At the same time, the slide plate is installed in the slide to assist in supporting the fixed plate, so that the fixed plate can better drive the stirring plate, the guide plate and the cone rod to move. And when the fixed plate moves, it will move with the connecting plate through the slide plate, and the guide plate and the cone rod on the connecting plate will assist in stirring the feed in other places in the storage box for mixing. This effectively drives the feed in other places in the storage box to be fully mixed, avoiding the situation where only the feed near the stirring plate is mixed, resulting in poor mixing effect. By installing a multi-stage telescopic plate, the leakage of feed in the storage box can be effectively reduced, and while reducing feed leakage, it can also assist the movement of the sleeve plate. When the discharge pipe completes the work of discharging feed, the pump in the storage box discharges feed at the same time. At this time, the electric push rod is used to slide the adjustment plate and the multi-section telescopic plate away from the discharge pipe, so that the gas in the multi-stage telescopic plate is blown to the part of the adjustment plate in the discharge pipe through the air guide pipe, thereby blowing off the residual feed on the adjustment plate and reducing the feed remaining on the adjustment plate.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 9As shown, a feeding device for deep-sea aquaculture of large yellow croaker according to an embodiment of the present invention comprises a cage frame 1, a farming net 2 is fixedly installed at the bottom of the cage frame 1; and a spreading mechanism 10 is arranged at the top of the cage frame 1. The spreading mechanism 10 comprises two bottom plates 11 fixedly installed at the top of the cage frame 1, a first servo motor 12 is attached to the bottom plate 11 by screws, a first screw rod 13 is fixedly installed at the output end of the first servo motor 12, a first base 14 is movably connected to the first screw rod 13, a second servo motor 15 is attached to the first base 14 by screws, a second screw rod 16 is fixedly installed at the output end of the second servo motor 15, a second base 17 is movably connected to the surface of the second screw rod 16, a storage box 18 for loading feed is fixedly installed at the top of the second base 17, and a discharge pipe 19 connected to the inside of the storage box 18 is fixedly installed at the bottom of the storage box 18.

[0040] Specifically, a support mechanism 20 is provided on the top of the cage frame 1, and the support mechanism 20 includes a support block 21 fixedly mounted on the top of the cage frame 1, a slider 22 is slidably connected in a rectangular groove on the top of the support block 21, and one end of the second screw rod 16 away from the second servo motor 15 is connected to the slider 22. Top plates 23 are fixedly mounted on both sides of the slider 22, and the cross section of the top plate 23 is triangular.

[0041] During operation, the required feed is loaded into the storage box 18 in advance. When the large yellow croaker seedlings in the culture net 2 need to be fed, the first servo motor 12 on the bottom plate 11 is started, so that the first screw rod 13 on the first servo motor 12 moves vertically with the first base 14 and the second servo motor 15. At the same time, the second servo motor 15 is started, so that the second screw rod 16 on the second servo motor 15 moves horizontally with the storage box 18 on the second base 17. It should be noted that the above movements are all uniform and slow movements. At this time, the pump in the storage box 18 is started to extract the feed and discharge it through the discharge pipe 19. By using the uniform and slow movement in the horizontal and vertical directions, the feed falling into the culture net 2 can be effectively dispersed in various positions, effectively avoiding the excessive concentration of the scattered feed in a certain place. Thereby effectively solving the problem that after the fish school is over-concentrated during feeding, the inner fish school over-eats, and the outer fish school is difficult to approach, resulting in the large yellow croaker seedlings in the same culture net 2. The situation of different food intake and large size differences occurs.

[0042] The slider 22 installed at the same time can assist in supporting the second screw rod 16 and cooperate with the second screw rod 16 to slide in the rectangular groove of the support block 21. At the same time, the sliding slider 22 can also use the triangular top plate 23 to clean the rectangular groove and reduce impurities in the rectangular groove, thereby ensuring that the slider 22 slides normally in the rectangular groove of the support block 21.

[0043] A guide mechanism 30 is provided in the discharge pipe 19 , and the guide mechanism 30 includes a filter screen 31 fixedly installed in the discharge pipe 19 , a trumpet-shaped guide column 32 is fixedly installed at the bottom of the filter screen 31 , and a hole penetrating the guide column 32 is provided at the top.

[0044] During operation, when the feed flows out through the discharge pipe 19, the installed guide column 32 can effectively guide part of the feed to the surroundings, while the other part of the feed falls directly through the holes on the guide column 32. The designed guide column 32 can make part of the feed fall to the bottom while the other part of the feed falls to the surroundings, so as to feed the large yellow croaker seedlings on the periphery, and play a role in more uniform feeding of the feed. At the same time, the installed filter 31 can effectively reduce the impurities entering the discharge pipe 19 while ensuring that the feed can pass.

[0045] An adjustment mechanism 40 is provided on one side of the storage box 18 close to the discharge pipe 19. The adjustment mechanism 40 includes an electric push rod 41 fixedly installed on the storage box 18. An adjustment plate 42 is fixedly installed on the output end of the electric push rod 41. The adjustment plate 42 is sealingly and slidingly connected to the discharge pipe 19. One side of the discharge pipe 19 is rotatably connected to a cover plate 43 through a torsion spring.

[0046] Specifically, the electric push rod 41 is provided with a stirring assembly 44, which includes a through slot 441 provided at the bottom of the storage box 18, a sleeve plate 442 is fixedly installed on the output end of the electric push rod 41, a fixing plate 443 is fixedly installed on the top of the sleeve plate 442, the fixing plate 443 is in the storage box 18, a stirring plate 444 is fixedly installed on the top of the fixing plate 443, a stirring plate 444 is provided with a plurality of through holes 445 penetrating the stirring plate 444 on one side, and a protective assembly 47 is provided in the through slot 441. A plurality of auxiliary assemblies 45 are provided on the surface of the stirring plate 444, and the auxiliary assemblies 45 include a plurality of guide plates 451 fixedly installed on both sides of the stirring plate 444, the two sides of the guide plate 451 are arc-shaped, and a plurality of cone rods 452 are fixedly installed on the arc-shaped surface of the guide plate 451. A connecting component 46 is provided in the storage box 18, and the connecting component 46 includes two slide grooves 461 symmetrically opened in the storage box 18, a slide plate 462 is fixedly installed in the slide groove 461, both sides of the fixed plate 443 are fixedly connected to the slide plate 462, a plurality of connecting plates 463 are fixedly installed between the two slide plates 462, and a plurality of stirring plates 444, guide plates 451 and cone rods 452 are fixedly installed on the top of the connecting plate 463.

[0047] Specifically, the protection assembly 47 includes two multi-stage telescopic plates 471 fixedly installed in the through slot 441. The multi-stage telescopic plate 471 is composed of a plurality of hollow plates slidably connected. One end of the multi-stage telescopic plate 471 is fixedly connected to the through slot 441 of the storage box 18, and one end of the multi-stage telescopic plate 471 is fixedly connected to the sleeve plate 442. The plurality of hollow plates in the multi-stage telescopic plate 471 are sealed and slidably connected. An air guide 472 connected to the interior is fixedly installed at one end of the multi-stage telescopic plate 471, and one end of the air guide 472 away from the multi-stage telescopic plate 471 is in the discharge pipe 19.

[0048] During operation, the amount of feed discharged from the discharge pipe 19 is changed according to the amount of feed that needs to be put in at different times of the large yellow croaker, and the electric push rod 41 at the bottom of the storage box 18 is started. The output end of the electric push rod 41 is used to slide the adjustment plate 42 in the direction away from the discharge pipe 19, so that there is a gap between the adjustment plate 42 and the inner wall of the discharge pipe 19, so that the feed can flow out through the discharge pipe 19. The gap between the adjustment plate 42 and the inner wall of the discharge pipe 19 is controlled according to actual needs. At the same time, after one end of the adjustment plate 42 enters the discharge pipe 19, the end cover is no longer lifted by the adjustment plate 42, and it will rotate and reset under the action of the torsion spring, thereby closing the side of the discharge pipe 19 to prevent the feed from leaking from the side.

[0049] When the feed is placed in the storage box 18 for a long time, the grease and powdery components in the feed will separate or settle to the bottom, which will cause the nutritional components of the feed to be uneven each time it is fed. Therefore, by installing the sleeve plate 442, the fixed plate 443, the stirring plate 444, the guide plate 451 and the cone rod 452 on the output end of the electric push rod 41 and following the movement, the stirring plate 444, the guide plate 451 and the cone rod 452 are used to stir the feed stored in the storage box 18 for a long time. At the same time, the several through holes 445 opened on the stirring plate 444 can effectively allow the feed to circulate, reducing the difficulty of the feed to flow and mix when stirred due to the increase of parts. At the same time, the slide plate 462 is installed in the chute 461 to assist in supporting the fixed plate 443, so that the fixed plate 443 can better drive the stirring plate 444, the guide plate 451 and the cone rod 452 to move. When the fixed plate 443 moves, it will move with the connecting plate 463 through the slide plate 462, and the guide plate 451 and the cone rod 452 on the connecting plate 463 will help stir the feed in other places in the storage box 18 for mixing. This effectively drives the feed in other places in the storage box 18 to be fully mixed, avoiding the situation where only the feed near the stirring plate 444 is mixed, resulting in poor mixing effect.

[0050] The installation of the multi-stage telescopic plate 471 can effectively reduce the leakage of feed in the storage box 18, and can assist the movement of the sleeve plate 442 while reducing the leakage of feed. When the discharge pipe 19 completes the work of discharging feed, the pump in the storage box 18 discharges feed at the same time. At this time, the electric push rod 41 is used to slide the adjustment plate 42 and the multi-section telescopic plate away from the discharge pipe 19 (it should be noted that the adjustment plate 42 will not completely separate from the discharge pipe 19), so that the gas in the multi-stage telescopic plate 471 is blown to the part of the adjustment plate 42 in the discharge pipe 19 through the air guide pipe 472, thereby blowing off the residual feed on the adjustment plate 42 and reducing the residual feed on the adjustment plate 42.

[0051] Working principle: By pre-loading the required feed into the storage box 18, when it is necessary to feed the yellow croaker seedlings in the breeding net 2, the first servo motor 12 on the bottom plate 11 is started, so that the first screw rod 13 on the first servo motor 12 moves vertically with the first base 14 and the second servo motor 15. At the same time, the second servo motor 15 is started, so that the second screw rod 16 on the second servo motor 15 moves horizontally with the storage box 18 on the second base 17. At this time, the pump in the storage box 18 is started to extract the feed and discharge it through the discharge pipe 19. The slider 22 installed at the same time can assist in supporting the second screw rod 16 and cooperate with the second screw rod 16 to slide in the rectangular groove of the support block 21. At the same time, the sliding slider 22 can also use the triangular top plate 23 to clean the rectangular groove. When the feed flows out through the discharge pipe 19, the installed guide column 32 can effectively guide part of the feed to the surroundings, while the other part of the feed falls directly through the holes on the guide column 32.

[0052] The output end of the electric push rod 41 is used to slide the adjustment plate 42 in the direction away from the discharge pipe 19, so that there is a gap between the adjustment plate 42 and the inner wall of the discharge pipe 19, so that the feed can flow out through the discharge pipe 19. The gap between the adjustment plate 42 and the inner wall of the discharge pipe 19 is controlled according to actual needs. At the same time, after one end of the adjustment plate 42 enters the discharge pipe 19, the end cover is no longer lifted by the adjustment plate 42, and it will rotate and reset under the action of the torsion spring, thereby closing the side of the discharge pipe 19. By installing the sleeve plate 442, the fixing plate 443, the stirring plate 444, the guide plate 451 and the cone rod 452 on the output end of the electric push rod 41 and following the movement, the stirring plate 444, the guide plate 451 and the cone rod 452 are used to stir the feed stored in the storage box 18 for a long time, and the plurality of through holes 445 opened on the stirring plate 444 can effectively allow the feed to circulate, reducing the difficulty of the feed to flow and mix when stirred due to the added parts. Meanwhile, the slide plate 462 is installed in the chute 461 to assist in supporting the fixed plate 443, so that the fixed plate 443 can better drive the stirring plate 444, the guide plate 451 and the cone rod 452 to move. When the fixed plate 443 moves, it will move with the connecting plate 463 through the slide plate 462, and the guide plate 451 and the cone rod 452 on the connecting plate 463 will assist in stirring the feed in other places in the storage box 18 for mixing. By installing the multi-stage telescopic plate 471, the leakage of the feed in the storage box 18 can be effectively reduced, and the sleeve plate 442 can be assisted in moving while reducing the leakage of the feed. When the discharge pipe 19 completes the task of discharging the feed, the pump in the storage box 18 also discharges the feed. At this time, the electric push rod 41 is used to slide the adjustment plate 42 and the multi-section telescopic plate away from the discharge pipe 19, so that the gas in the multi-stage telescopic plate 471 is blown toward the part of the adjustment plate 42 in the discharge pipe 19 through the air guide pipe 472, thereby blowing off the residual feed on the adjustment plate 42 and reducing the amount of feed remaining on the adjustment plate 42.
