Description

Technical Field

[0001] The present invention relates to the technical field of abalone farming, and more particularly to a bottom-mounted automatic feeding device for deep-sea abalone farming. Background Art

[0002] A deep-sea aquaculture cage is a tool for deep-sea aquaculture, mainly composed of a frame system, a net bag, a fixing system and supporting facilities. It uses the interaction of the fixing platform and the characteristics of the box itself to lower the box to a limited depth underwater.

[0003] After retrieval, the patent document with the authorization announcement number CN215774935U discloses a feeding device for deep-sea cage aquaculture. Its spiral blades rotate synchronously clockwise to convey the bait deposited at the bottom of the chamber upward, thereby improving the mixing uniformity of the bait and the mixing efficiency of the bait. After the spiral blades rotate counterclockwise, the bait is discharged outward, improving the discharge efficiency of the bait in the chamber, reducing the blockage of the device, and improving the practicability of the device; it includes a tank body, a discharge pipe, an electromagnetic valve, a feed pipe, a stable support, a rotating shaft, spiral blades, a stirring rod, a first flywheel, a first motor, a first belt, a third flywheel, a second motor, a second belt and a feeding device. The tank body is installed at the top of the cage, a chamber is arranged inside the tank body, a feed inlet and a discharge outlet are arranged inside the chamber, and both the feed inlet and the discharge outlet communicate with the inside of the chamber. The top of the discharge pipe is connected to the bottom of the tank body and communicates with the discharge outlet of the chamber. The electromagnetic valve is connected and arranged at the output end of the discharge pipe.

[0004] Based on the retrieval and the prior art, it can be known that: in the existing abalone farming technology, abalones are generally placed in a closed aquaculture cage, and then fed regularly, generally once every five days. There are two existing feeding methods. The first one is manual. First, the aquaculture cage is lifted, then the aquaculture cage is opened for feeding, and after closing the aquaculture cage, it is put into the deep sea. The second one is to use the feeding device as retrieved above, place the feeding pipe on the top of the aquaculture cage and connect it to the aquaculture cage for feeding. The second feeding method is more convenient, but there is a drawback. The aquaculture cage is in deep water, and the feeding pipe will also be filled with seawater. When the feed enters the feeding pipe, the feeding pipe is relatively long. Even with the push of air pressure, it needs to sink slowly (in order to make the feed sink into the aquaculture cage, the feed generally contains an anti-floating agent). This process is relatively slow. If the aquaculture water area is relatively deep, it may take several hours to sink, so that the abalones cannot eat in time, affecting the aquaculture process.

[0020] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0021] The present invention provides a bottom - sitting automatic feeding device for deep - sea abalone farming by improvement. The technical solution of the present invention is as follows: As Figures 1 to 10 shown, the embodiment of the present invention provides a bottom - sitting automatic feeding device for deep - sea abalone farming, including a support 3, a vertical pipe 4, a transition pipe 9, a feeding pipe 5, a circular steel wire 6 and a plurality of soft spheres 7. One end of the vertical pipe 4 is fixedly arranged inside the support 3; One end of the feeding pipe 5 is sleeved and fixed on the other end of the vertical pipe 4, and the other end of the feeding pipe 5 is inserted and fixed on the top of an existing aquaculture net cage. The bottom of the vertical pipe 4 can be made into a trumpet shape to facilitate the sliding of the soft sphere 7; The whole of the transition pipe 9 is embedded in the top of an existing aquaculture net cage, and the diameter of the pipe orifice at one end of the transition pipe 9 located inside the aquaculture net cage gradually expands downward. A part of the circular steel wire 6 is located inside the transition pipe 9. The setting of the transition pipe 9 plays a guiding role to facilitate the removal of the soft sphere 7 from the top of the aquaculture net cage; Both the transition pipe 9 and the vertical pipe 4 are made of corrosion - resistant steel; A plurality of soft spheres 7 are provided with through holes 12 whose central axes pass through the centers of the soft spheres 7, and a plurality of soft spheres 7 are all sleeved on the circular steel wire 6 through the through holes 12. A fixing structure for fixing the two is arranged between the soft spheres 7 and the circular steel wire 6, and each soft sphere 7 is equidistantly distributed on the circular steel wire 6. The diameter of the soft sphere 7 is adapted to the inner diameter of the feeding pipe 5. Here, it is supplemented that the diameter of the soft sphere 7 being adapted to the inner diameter of the feeding pipe 5 is just a design. It can be designed that the diameter of the soft sphere 7 is slightly larger than the inner diameter of the feeding pipe 5. Although it will increase the moving friction, the sealing performance between the soft sphere 7 and the feeding pipe 5 is improved; similarly, it can also be designed that the diameter of the soft sphere 7 is slightly smaller than the inner diameter of the feeding pipe 5, reducing the friction loss, but the movement of the soft body is more convenient; The movable through-transition pipe 9 and the feeding pipe 5 of the loop-shaped steel rope 6 penetrate through; A transmission mechanism for moving the loop-shaped spring is arranged inside the support 3; From the above connection relationship, it can be seen that in the present invention: a part of the loop-shaped steel rope 6 is arranged inside the feeding pipe 5, and a plurality of soft spheres 7 are arranged at equal intervals on the outer side of the loop-shaped steel rope 6. The sphere diameter of the soft spheres 7 is adapted to the inner diameter of the feeding pipe 5. The present invention also has a transmission mechanism that can move the loop-shaped steel rope 6, so that each soft sphere 7 can pass through the feeding pipe 5. At this time, the feed can be placed between two adjacent soft spheres 7. During the movement of the soft spheres 7 in the feeding pipe 5, the feed is put into the aquaculture net cage, so that the feed does not need to sink independently, thereby improving the feeding speed and ensuring that abalones can eat in time.

[0022] Specifically, as shown in the attached Figure 1 figures, it also includes a conveyor 1 and a water pump 2. The conveyor 1 is a screw feeder, which is a common solid feed conveying machine in the prior art. The feeding end of the conveyor 1 is fixed and communicated with the outer side of the vertical pipe 4. The water suction end of the water pump 2 is fixed with a water suction hose 8 communicated therewith. One end of the water suction hose 8 is fixedly communicated with the bottom of one side of the aquaculture net cage; the water pump 2 sucks away the metabolites in the aquaculture net cage. After the water pump 2 works for a period of time, the water pump 2 is turned off. It should be noted here that the water pump 2 cannot pump water with high power to prevent sucking away the abalones.

[0023] The feeding pipe 5 and the water suction hose 8 are both made of neoprene, which is one of the commonly used materials for deep-sea hoses. Neoprene has the advantages of high wear resistance and corrosion resistance. The inside of the feeding pipe 5 and the water suction hose 8 are both framed by a stainless steel wire braided net, and the stainless steel wire can improve the tear resistance of the feeding pipe 5 and the water suction hose 8.

[0024] Specifically, as shown in the attached Figure 4 and the attached Figure 5As shown, the material of the soft sphere 7 is selected as nitrile rubber, which has the advantages of high wear resistance, corrosion resistance, etc., and nitrile rubber is relatively smooth, so that the soft sphere 7 can easily slide into the feeding pipe 5. Two countersunk holes 13 are opened on the outer side of the soft sphere 7. The central axis of the countersunk hole 13 passes through the central axis of the through hole 12, and the central axis of the countersunk hole 13 is perpendicular to the central axis of the through hole 12. The fixing structure includes a pressing plate 14, two hexagon bolts and two hexagon socket head cap nuts. Since the steel wire rope is made of twisted steel wires, a certain knot of the steel wire rope is loosened, and the pressing plate 14 is fixed to the loosened part by welding. Then the pressing plate 14 is placed in the through hole 12 of the soft sphere 7. Two positioning holes 15 are opened on the plate surface of the pressing plate 14. The two hexagon bolts respectively pass through the two countersunk holes 13 and the two positioning holes 15, and then the two hexagon socket head cap nuts are respectively screwed onto the two hexagon bolts. Here, it should be supplemented that the above only introduces one fixing method of the fixing structure, and the specific structure of the fixing structure is not limited.

[0025] Specifically, in combination with the attached Figure 4 As shown, a plurality of annular grooves 11 coaxial with the through hole 12 are opened on the spherical surface of the soft sphere 7; if the ball diameter of the soft sphere 7 is slightly larger than the inner diameter of the feeding pipe 5, the annular grooves 11 reduce the sliding resistance of the soft sphere 7, and at the same time, the annular grooves 11 can clean the inner wall of the feeding pipe 5.

[0026] Specifically, in combination with the attached Figures 6 - 10 As shown, the transmission mechanism includes a rotating wheel 19, a rotating shaft 18 and two side plates 17. The two side plates 17 are both fixed to the bracket 3 and are exactly aligned with each other. Rotating holes are opened on the opposite sides of the two side plates 17. The two ends of the rotating shaft 18 are respectively rotatably installed in the two rotating holes. The rotating shaft 18 is coaxially fixed with the rotating wheel 19. A servo reduction motor 16 is fixed on the outer side of one of the side plates 17. The output shaft of the servo reduction motor 16 is coaxially fixed with the rotating shaft 18. An annular groove coaxial with it is opened at the middle position of the wheel surface of the rotating wheel 19. A plurality of equally spaced and annularly distributed embedding grooves 24 are also opened on the wheel surface of the rotating wheel 19. The embedding groove 24 is composed of a straight hole groove and a hemispherical groove. The inner ball diameter of the hemispherical groove is the same as the outer diameter of the soft sphere 7. Some of the soft spheres 7 on the circular steel wire rope 6 are movably embedded in the embedding grooves 24, and the circular steel wire rope between two adjacent soft spheres 7 is located in the wire groove 23. The outer side edge of the wire groove 23 and the hole edge of the straight groove hole are both rounded. The setting of the rounded corners is to facilitate the sliding of the soft sphere 7 and the wire groove 23, and at the same time reduce sharp wear; the rounded corner at the hole edge of the straight groove hole is made as large as possible to facilitate the embedding of the soft sphere 7. A limiting structure 10 for preventing the soft sphere 7 from coming out of the embedding groove 24 is arranged between the two side plates 17; start the servo reduction motor 16, and the servo reduction motor 16 rotates through the rotating shaft 18 to attach Figure 2 And attach Figure 9For example, the rotating wheel 19 rotates clockwise, and the rotating wheel 19 on the rotating shaft 18 drives the soft ball 7 to be pushed through the embedded groove 24, so that the ring steel rope is transmitted clockwise, and the vertical pipe 4 and the soft ball 7 in the feeding pipe 5 move from top to bottom, and the soft ball 7 transfers the feed in the vertical pipe 4 to the feeding pipe 5.

[0027] Specifically, in combination with Figures 7 - 9 As shown, the limiting structure 10 includes a large concave plate 20 and a small concave plate 21, the large concave plate 20 and the small concave plate 21 are both arranged between the two side plates 17 and fixed to the two side plates 17, the concave bottom of the large concave plate 20 is downward and the concave bottom is arc-shaped, the rotating wheel 19 is located in the concave bottom of the large concave plate 20 and the two are coaxially arranged, the concave bottom of the small concave plate 21 is upward and located in the middle below the rotating wheel 19, and the two corners of the bottom of the small concave plate 21 are both chamfered; when the soft ball 7 enters between the large concave plate 20 and the small concave plate 21, the soft ball 7 cannot swing, so that the soft ball 7 cannot escape from the embedded groove 24; at the same time, the closer the soft ball 7 is to the rotating wheel 19, the more the steel rope enters the wire groove 23, and the more difficult it is for the soft ball 7 to shake. Since the edge of the straight slot hole is chamfered, the soft ball 7 is easier to embed into the embedded groove 24.

[0028] Specifically, in combination with Figure 7 The inner side of the large concave plate 20 and the outer side of the small concave plate 21 are both provided with concave grooves that are consistent with each other's contour paths, and a plurality of transversely arranged rolling rollers 22 are rotatably installed inside the concave grooves; the rolling rollers 22 are arranged to reduce friction loss.

[0029] Specifically, in combination with Figure 6 and attached Figure 7 As shown, the bottoms of the two side plates 17 and both ends of the bottom of the concave plate are bent away from the rotating wheel 19. The above bending setting is to facilitate the soft ball head to slide into the large concave plate 20 and the small concave plate 21, while reducing sharp wear.

[0030] Working principle: The first step is to fix the conveyor 1, the bracket 3 and the water pump 2 on the breeding platform (the platform is generally set on a floating operation platform on a sponge to provide a foothold for workers. For existing operations, its specific structure and working principle will not be elaborated in detail here); The second step is to place the abalone in the breeding net cage and perform a sealing treatment, and then the feeding pipe 5 is plugged and fixed on the top of the breeding net cage (an internal thread joint connected to the inside can be fixed on the top of the breeding net cage, and an external thread joint adapted to the internal thread joint is fixed at one end of the feeding pipe 5, and the feeding pipe 5 is fixed to the breeding net cage by using the internal thread joint and the external thread joint), and then the breeding net cage is placed in the deep sea; The third step is to pour the feed into the storage box of the conveyor 1 for storage; Step 4: Conduct regular feeding; The feeding process is as follows: (1) First, start the water pump 2. The water pump 2 sucks away the metabolites in the aquaculture cage (mainly sucks away the metabolites deposited at the bottom of the aquaculture cage. At the same time, when the water pump 2 sucks water, the flow rate of seawater in the aquaculture cage increases, which will also disperse part of the metabolites, enabling the metabolites to pass through the cage). After the water pump 2 works for a period of time, turn off the water pump 2. It should be noted here that the water pump 2 cannot pump water at high power to prevent sucking away the abalones; (2) Start the conveyor 1. The conveyor 1 transports a part of the feed in the storage box into the vertical pipe 4; (3) When (2) is in progress, start the servo reduction motor 16. The servo reduction motor 16 rotates through the rotating shaft 18, taking Figure 2 and taking Figure 9 as an example, the rotating wheel 19 rotates clockwise. The rotating wheel 19 on the rotating shaft 18 drives the soft sphere 7 to move through the embedding groove 24, so that the circular steel rope drives clockwise. The soft spheres 7 in the vertical pipe 4 and the feeding pipe 5 move from top to bottom. The soft sphere 7 transfers the feed in the vertical pipe 4 to the feeding pipe 5 and pushes it into the aquaculture cage from the feeding pipe 5, so as to feed the feed into the aquaculture cage from a high place, enabling the abalones to eat in time; (4) First, turn off the conveyor 1, keep the servo reduction motor 16 in the starting state, and let the servo reduction motor 16 work for a period of time, so as to ensure that the feed in the feeding pipe 5 can be completely fed into the aquaculture cage (here, a supplementary explanation is made. One soft sphere 7 can be dyed separately to distinguish it from other soft spheres 7. When the dyed soft sphere 7 returns to the original position again or multiple times, it proves that the circular steel rope 6 has circulated one circle. At this time, the feed in the feeding pipe 5 can be completely fed into the aquaculture cage, and then the servo reduction motor 16 can be turned off); (5) For the next feeding, just repeat steps (1)-(4).

[0031] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
