Description

Technical Field

[0001] The invention relates to the technical field of abalone farming, in particular to a bottom-sitting automatic feeding device for deep-sea abalone farming. Background Art

[0002] Deep-sea aquaculture cages are a tool used for deep-sea aquaculture. They are mainly composed of a frame system, a net bag, a fixing system and supporting facilities. The cage is lowered to a limited depth underwater by utilizing the interaction of the fixed platform and the characteristics of the cage itself.

[0003] After searching, the patent document with authorization announcement number CN215774935U discloses a deep-sea cage aquaculture feeding device, wherein the spiral blades rotate synchronously clockwise to transport the bait deposited at the bottom of the chamber upward, thereby improving the mixing uniformity of the bait and improving the mixing efficiency of the bait. The spiral blades rotate counterclockwise to discharge the bait outward, thereby improving the discharge efficiency of the bait in the chamber, reducing the blockage of the device and improving the practicality of the device; it includes a tank body, a discharge pipe, an electromagnetic valve, a feed pipe, a stabilizing bracket, a rotating shaft, a spiral blade, 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 provided in the tank body, a feed port and a discharge port are provided in the chamber, the feed port and the discharge port are both communicated with the chamber, the top of the discharge pipe is connected to the bottom end of the tank body and communicated with the chamber discharge port, and the electromagnetic valve is connected to the output end of the discharge pipe.

[0004] Based on the search and existing technology, it can be known that the existing abalone farming technology generally places abalone in a closed farming cage, and then feeds them regularly, generally once every five days. There are two existing feeding methods. The first is manual, first, the farming cage is picked up, then the farming cage is opened for feeding, and then the farming cage is closed and thrown into the deep sea; the second is to use the above-mentioned retrieval and feeding device, and the feeding pipe is placed on the top of the farming cage and connected to the farming cage for feeding; the second feeding method is more convenient, but there is a disadvantage. The farming cage is in deep water, and the feeding pipe will also be filled with seawater. The feed enters the feeding pipe. The feeding pipe is long, and even if there is air pressure, it needs to be slowly settled (in order to make the feed sink into the farming cage, the feed generally contains anti-floating agents). This process is relatively slow. If the farming water is deep, it may take several hours to settle, so that the abalone cannot eat in time, affecting the farming process. Summary of the Invention

Since the steel rope is made of twisted steel wire, a certain knot of the steel rope is loosened, and the pressure plate is fixed to the loose strand by welding. The pressure plate is then placed in the through hole of the soft sphere, and two positioning holes are provided on the plate surface of the pressure plate.

[0018] The two wheels are fixed to the two support brackets and are aligned with each other, and a rotating hole is provided on the opposite side of the two side plates, and the two ends of the rotating shaft are rotatably mounted in the two rotating holes. The rotating shaft is coaxially fixed to the rotating wheel, and a servo reduction motor is fixed to the outside of one of the side plates, and the output shaft of the servo reduction motor is coaxially fixed to the rotating shaft.

[0039] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] The present invention provides a bottom-standing automatic feeding device for deep-sea abalone farming through improvement. The technical solution of the present invention is:

[0041] like Figures 1 to 10 As shown, the embodiment of the present invention provides a bottom-standing automatic feeding device for deep-sea abalone farming, comprising a bracket 3, a vertical pipe 4, a transition pipe 9, a feeding pipe 5, a coiled steel rope 6, and a plurality of soft balls 7, wherein one end of the vertical pipe 4 is fixed outside the bracket 3;

[0042] 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 plugged and fixed on the top of the existing breeding cage. The bottom of the vertical pipe 4 can be made into a trumpet shape to facilitate the sliding of the soft ball 7;

[0043] The entire transition pipe 9 is embedded in the top of the existing aquaculture cage, and the diameter of the pipe opening at one end of the transition pipe 9 located in the aquaculture cage gradually expands downward. A portion of the looped steel rope 6 is located in the transition pipe 9. The setting of the transition pipe 9 plays a guiding role, making it convenient for the soft ball 7 to be removed from the top of the aquaculture cage.

[0044] The transition pipe 9 and the vertical pipe 4 are both made of corrosion-resistant steel;

[0045] A through hole 12 is provided on the outer side of the plurality of soft spheres 7, the central axis of which passes through the center of the soft sphere 7, and the plurality of soft spheres 7 are sleeved on the coiled steel rope 6 through the through hole 12. A fixing structure is provided between the soft sphere 7 and the coiled steel rope 6 to fix the two, and the soft spheres 7 are distributed at equal distances on the coiled steel rope 6. The ball diameter of the soft sphere 7 is adapted to the inner diameter of the feeding tube 5. It is supplemented here that the adaptation of the ball diameter of the soft sphere 7 to the inner diameter of the feeding tube 5 is only a design. The ball diameter of the soft sphere 7 can be designed to be slightly larger than the inner diameter of the feeding tube 5. Although it will increase the movement friction, the sealing performance of the soft sphere 7 and the feeding tube 5 is improved. Similarly, the ball diameter of the soft sphere 7 can also be designed to be slightly smaller than the inner diameter of the feeding tube 5 to reduce friction loss, but the soft body is more convenient to move.

[0046] The coiled steel rope 6 runs through the transition pipe 9 and the feeding pipe 5;

[0047] A transmission mechanism for moving the coiled steel rope 6 is provided inside the bracket 3;

[0048] From the above connection relationship, it can be seen that the present invention: a part of the looped steel rope 6 is arranged inside the feeding tube 5, and a plurality of soft balls 7 are arranged on the outside of the looped steel rope 6 at equal intervals. The ball diameter of the soft ball 7 is adapted to the inner diameter of the feeding tube 5. The present invention is also provided with a transmission mechanism, which can make the looped steel rope 6 move so that each soft ball 7 can pass through the feeding tube 5. At this time, the feed can be placed between two adjacent soft balls 7. During the movement of the feeding tube 5, the soft ball 7 puts the feed into the breeding cage, so that the feed does not need to sink independently, thereby improving the feeding speed and ensuring that the abalone can eat in time.

[0049] Specifically, in conjunction with Figure 1 As shown, it also includes a conveyor 1 and a water pump 2. The conveyor 1 is a screw feeder, which is a solid feed conveying machine 1 commonly used in the prior art. The feeding end of the conveyor 1 is fixed and connected to the outer side of the vertical pipe 4. The water pumping end of the water pump 2 is fixed with a water pumping hose 8 connected thereto, and one end of the water pumping hose 8 is fixedly connected to the bottom of one side of the breeding cage; the water pump 2 sucks away the metabolites in the breeding cage, and 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 perform high-power pumping to prevent the abalone from being sucked away.

[0050] The material of the feeding pipe 5 and the water suction hose 8 are both 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 interior of the feeding pipe 5 and the water suction hose 8 are both made of stainless steel wire woven mesh as the skeleton. The stainless steel wire can improve the tear resistance of the feeding pipe 5 and the water suction hose 8.

[0051] Specifically, in conjunction with Figure 4 and attached Figure 5 As shown, the material of the soft sphere 7 is nitrile rubber, which has the advantages of high wear resistance and corrosion resistance, and nitrile rubber is relatively smooth, so that the soft sphere 7 can slide into the feeding tube 5 very well. Two countersunk holes 13 are provided on the outside 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 hexagonal bolts and two hexagonal nuts. Since the steel rope is made of twisted steel wire, a certain knot of the steel rope is loosened, and the pressing plate 14 is fixed to the loose strand by welding. The pressing plate 14 is then placed in the through hole 12 of the soft sphere 7. The plate surface of the pressing plate 14 is provided with two positioning holes 15. The two hexagonal bolts pass through the two countersunk holes 13 and the two positioning holes 15 respectively, and then the two hexagonal nuts are screwed on the two hexagonal bolts respectively. Here is a supplementary explanation. The above only introduces a fixing method of the fixing structure, and does not limit the specific structure of the fixing structure.

[0052] Specifically, in conjunction with Figure 4 As shown, the spherical surface of the soft ball 7 is provided with a plurality of annular grooves 11 coaxially arranged with the through hole 12; if the diameter of the soft ball 7 is slightly larger than the inner diameter of the feeding tube 5, the annular grooves 11 reduce the resistance of the soft ball 7 to sliding in, and at the same time, the annular grooves 11 can clean the inner wall of the feeding tube 5.

[0053] Specifically, in conjunction with Figure 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 fixed to the bracket 3 and the two are aligned. A rotating hole is opened on the opposite side 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 to the outside of one of the side plates 17. The output shaft of the servo reduction motor 16 is coaxially fixed with the rotating shaft 18. A ring groove coaxially arranged with the rotating wheel 19 is opened in the middle position of the wheel surface of the rotating wheel 19. The wheel surface of the rotating wheel 19 also has a plurality of equidistant and annular embedded grooves 24, and the embedded grooves 24 are composed of straight hole grooves. The soft ball 7 is composed of a hemispherical groove, the inner diameter of the hemispherical groove is consistent with the outer diameter of the soft ball 7, part of the soft ball 7 on the ring-shaped steel rope 6 is movably embedded in the embedding groove 24, and the ring-shaped steel rope between the two adjacent soft balls 7 is located in the wire groove 23, the outer side of the wire groove 23 and the hole edge of the straight groove hole are chamfered, and the rounded corners are set to facilitate the sliding of the soft ball 7 and the wire groove 23, while reducing sharp wear; the rounded corners of the hole edge of the straight groove hole are as large as possible to facilitate the embedding of the soft ball 7, and a limiting structure 10 is set between the two side plates 17 to prevent the soft ball 7 from escaping from the embedding groove 24; start the servo reduction motor 16, and the servo reduction motor 16 rotates through the rotating shaft 18 to attach Figure 2 And attached 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 push 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.

[0054] Specifically, in conjunction with Figure 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 notch of the large concave plate 20 faces downward and the bottom of the concave is arc-shaped. The rotating wheel 19 is located in the notch of the large concave plate 20 and the two are coaxially arranged. The notch of the small concave plate 21 faces upward and is located in the middle below the rotating wheel 19. 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 part of the steel rope enters the wire groove 23, and the soft ball 7 is more difficult to shake. Since the edge of the straight slot hole is chamfered, the soft ball 7 is easier to embed in the embedded groove 24.

[0055] Specifically, in conjunction 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 with the same contour path as each other, and a plurality of transversely arranged rolling rollers 22 are rotatably installed inside the concave grooves; the rolling rollers 22 are provided to reduce friction loss.

[0056] Specifically, in conjunction 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 large concave plate 20 are bent toward the side away from the rotating wheel 19. The above-mentioned 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.

[0057] Working principle:

[0058] 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 operating platform on a sponge to provide a foothold for workers. It is an existing operation, and its specific structure and working principle are not described in detail here);

[0059] In the second step, the abalone is placed in the breeding net cage and sealed, and then the feeding pipe 5 is plugged and fixed on the top of the breeding net cage (an internal threaded joint connected to the inside can be fixed on the top of the breeding net cage, and an external threaded joint adapted to the internal threaded joint is fixed at one end of the feeding pipe 5, and the internal threaded joint and the external threaded joint are utilized to fix the feeding pipe 5 to the breeding net cage), and then the breeding net cage is placed in the deep sea;

[0060] The third step is to pour the feed into the storage box of the conveyor 1 for storage;

[0061] The fourth step is to feed regularly;

[0062] The feeding process is:

[0063] (1) Start the water pump 2 first. The water pump 2 will suck away the metabolites in the aquaculture cage (mainly the metabolites deposited at the bottom of the aquaculture cage. At the same time, during the water pump 2's water suction process, the flow rate of seawater in the aquaculture cage will accelerate, which will also disperse some metabolites and allow the metabolites to pass through the cage). After the water pump 2 has worked for a while, turn off the water pump 2. It should be noted that the water pump 2 cannot be used for high-power pumping to prevent the abalone from being sucked away.

[0064] (2) Start the conveyor 1, which transports a portion of the feed in the storage box to the vertical pipe 4;

[0065] (3) When (2) is being performed, the servo reduction motor 16 is started, and the servo reduction motor 16 rotates through the rotating shaft 18 to attach Figure 2 And attached Figure 9 For example, the rotating wheel 19 rotates clockwise, and the rotating wheel 19 on the rotating shaft 18 drives the soft ball 7 to push through the embedded groove 24, so that the ring rope is driven clockwise, and the vertical pipe 4 and the soft ball 7 in the feeding pipe 5 move from top to bottom. The soft ball 7 feeds the vertical pipe 4 into the feeding pipe 5 and pushes it into the breeding cage from the feeding pipe 5, thereby sending the feed from a high place into the breeding cage, so that the abalone can eat in time;

[0066] (4) First, turn off the conveyor 1, keep the servo reduction motor 16 in the started state, and make 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 breeding net cage (here is a supplementary explanation, a soft ball 7 can be dyed separately to distinguish the soft ball 7 from other soft balls 7. When the dyed soft ball 7 returns to the original position again or multiple times, it proves that the coiled steel rope 6 has circulated one circle. At this time, the feed in the feeding pipe 5 can be completely fed into the breeding net cage, and the servo reduction motor 16 can be turned off at this time);

[0067] (5) Repeat steps (1) to (4) for the next feeding.

[0068] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
