Description

Technical Field

[0001] This invention relates to the field of fish breeding technology, specifically to an automatic feed dispensing device for shrimp fry farming. Background Technology

[0002] Feeding is a crucial step in shrimp larvae farming. Traditional feeding methods are mostly manual, which has many drawbacks.

[0003] Manual feeding is not only labor-intensive, requiring farmers to operate at fixed times and locations, consuming significant manpower and time, but also difficult to achieve precise feeding. The amount of feed is hard to control accurately, easily resulting in overfeeding or underfeeding. Overfeeding leads to feed waste, with uneaten feed remaining in the water, causing water pollution and affecting the shrimp larvae's growth environment. Underfeeding fails to meet the shrimp larvae's growth needs, resulting in slow growth and even affecting their survival rate.

[0004] Furthermore, traditional feeding methods are insufficient in terms of feed uniformity. Shrimp larvae from different areas may not receive the same amount of feed, leading to uneven growth and affecting overall farming results. At the same time, manual feeding makes it difficult to flexibly adjust according to the growth stage and actual needs of the shrimp larvae, hindering scientific and precise farming management.

[0005] With the continuous expansion of aquaculture scale, traditional manual feeding methods can no longer meet the needs of modern shrimp larvae farming. There is an urgent need for equipment that can achieve automatic, precise, and uniform feeding to improve farming efficiency, reduce costs, improve the farming environment, and ensure the healthy growth of shrimp larvae.

[0035] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 12This invention provides a technical solution: an automatic feed dispensing device for shrimp fry farming, comprising a plastic float tube 1, on which two sets of connecting rings 2 are fixedly fitted, and each set of connecting rings 2 is fitted with a float 4. Each set of connecting rings 2 has two floats. On both sides of the connecting rings 2, there are assembly grooves 3 on the outer ring surface. The assembly grooves 3 are annular grooves. The float 4 is a hollow semi-circular frame. The two ends of the float 4 are respectively fastened into the assembly grooves 3 on the surfaces of the two connecting rings 2. On both sides of the float 4, there are notches 29 at both ends. The interior of the notches 29 is fixed with a semi-stud 30. After the two floats 4 are assembled into a circular frame, the two semi-studs 30 are assembled into a connecting stud. A dispensing cylinder 21 is screwed onto the connecting stud. The notches 29 are semi-circular grooves. The length of the semi-stud 30 is equal to the depth of the notches 29. The surfaces of the two semi-studs 30 that are assembled into the connecting stud are threaded together.

[0037] In use, the plastic floating tube 1 is laid on the sea surface, and floats 4 are installed on the tube body of the plastic floating tube 1 to increase the buoyancy of the plastic floating tube 1. When installing the floats 4, two floats 4 are fastened to both sides of the plastic floating tube 1. When the two floats 4 are close together, the two ends of the floats 4 are respectively fastened into the splicing grooves 3 of the two connecting rings 2. At this time, the notches 29 at the ends of the two floats 4 are assembled into a circular groove. Nuts 21 are screwed onto the connecting studs of the two splicing half studs 30 and locked. At this time, the two floats 4 are pre-fixed between the two connecting rings 2. After the floats 4 are installed at both ends of the plastic floating tube 1, it is ensured that the plastic floating tube 1 floats stably on the sea surface.

[0038] Both sides of the pontoon 4 are provided with side grooves 5, which are arc-shaped. A long-shank screw 6 is screwed onto the inner ring surface of the side groove 5. One end of the long-shank screw 6 passes through the inner ring surface of the pontoon 4 and is screwed onto the surface of the assembly groove 3. Reflective strips 7 are fixed on the outer ring surface of the pontoon 4. There are two reflective strips 7, which are arranged side by side. In order to strengthen the connection between the pontoon 4 and the connecting ring 2, the long-shank screw 6 is screwed through the pontoon 4 and screwed onto the surface of the assembly groove 3. At this time, the pontoon 4 is firmly fixed to the connecting ring 2. The reflective strip 7 serves as a warning on the outside of the pontoon 4. An LED light strip 8 is wrapped around the outer ring surface of the connecting ring 2. Thus, the connecting ring 2 not only serves to connect the plastic float tube 1 to the pontoon 4, but also provides a warning function in conjunction with the reflective strip 7, and provides a lighting function in conjunction with the LED light strip 8. That is, the connecting ring 2 has multiple functions.

[0039] After the two plastic floats 1 are spliced ​​end to end, the two connecting rings 2 at the ends of the two plastic floats 1 are connected by bolts 10. The surface of the connecting rings 2 has multiple bolt holes 9. After the two plastic floats 1 are spliced ​​end to end, the connecting rings 2 at the ends of the two plastic floats 1 are close together, and the bolts 10 pass through the bolt holes 9 on the surface of the two connecting rings 2 and are locked. In this way, the connecting rings 2 not only serve the function of connecting the floats 4 to the plastic floats 1, but also provide a warning function in conjunction with the reflective strips 7, and provide a lighting function in conjunction with the LED light strips 8. In addition, the connecting rings 2 also serve as flanges when the two plastic floats 1 are connected. That is, the connecting rings 2 have multiple functions.

[0040] The plastic float tube 1 has two partitions 12 installed inside. A feeding port 17 is located at the top of the plastic float tube 1. A guide ring 11 is fixed to the inner wall of the plastic float tube 1. The guide ring 11 is a circular tube with a right-angled triangular cross-section. Two guide rings 11 are provided, symmetrically distributed about the feeding port 17, and positioned between the two partitions 12. The dispensing cylinder 21 is located between the two guide rings 11. Multiple screws 15 are fixed to the surface of the guide rings 11, and the screws 15 pass through through holes 14. The through holes 14 are located within the partitions. On the surface of plate 12, a nut 16 is screwed onto the end of screw rod 15. A sealing ring 13 is fixed on the outer side of partition plate 12 and clamped between partition plate 12 and plastic float tube 1. A cover 18 is inserted into the top of feed port 17. The surface of feed port 17 is provided with internal thread, and the outer wall of cover 18 is provided with external thread. The external thread and internal thread are connected. Multiple fine holes 19 are opened on the top surface of cover 18. A water-blocking and breathable surface layer 20 is fixed on the top surface of cover 18 and covers multiple fine holes 19.

[0041] In use, a guide ring 11 is pre-fixed to the inner wall of the plastic float 1. The inner ring diameter of the end of the guide ring 11 near the feeding port 17 is larger than the inner ring diameter of the other end of the guide ring 11. The two partitions 12 are pushed into the two ports of the plastic float 1 respectively. The partitions 12 are blocked by the corresponding guide rings 11. After the partitions 12 and guide rings 11 come into contact, the screw 15 passes through the through hole 14. The nut 16 is screwed onto the screw 15 and locked. At this time, the partitions 12 are firmly fixed to the guide rings 17. On one side of the feed ring 11, the guide ring 11 not only guides the feed stored between the two partitions 12 to the dispensing cylinder 21, but also serves as a connecting and limiting structure for the partitions 12, that is, the guide ring 11 has multiple uses; feed is fed from the feeding port 17 into the storage space inside the plastic float tube 1 that is separated by the two partitions 12, and then the cap 18 is inserted and screwed into the feeding port 17; at this time, the plastic float tube 1 is used not only as a traditional float tube, but also as a feed storage mechanism.

[0042] A dispensing cylinder 21 is inserted and fixed to the bottom of the plastic float tube 1, and a stopper plate 22 is inserted and fixed to the top of the dispensing cylinder 21. The stopper plate 22 is pulled by an electric push rod 24, which is fixed to the inner wall of the plastic float tube 1. A bolt conveying shaft 26 is rotatably connected to the bottom of the stopper plate 22, and the bolt conveying shaft 26 passes through the dispensing cylinder 21. The dispensing cylinder 21 has a cylindrical structure, and the stopper plate 22 has an inverted frustum plate. The top diameter of the stopper plate 22 is larger than the opening diameter of the dispensing cylinder 21. Traction plates 23 are fixed to both sides of the stopper plate 22, and the bottom end of the piston rod of the electric push rod 24 is fixed to the traction plate. On the top surface of 23, the electric push rod 24 and the traction plate 23 correspond one-to-one. The top surface of the plug plate 22 is fixed with a servo motor 25. The top end of the bolt feeding shaft 26 passes through the plug plate 22 and is connected to the power output end of the servo motor 25. The height of the bolt feeding shaft 26 is greater than the height of the dispensing cylinder 21. The bottom surface of the dispensing cylinder 21 is provided with a discharge port 32. The bolt feeding shaft 26 passes through the discharge port 32. The bottom end of the bolt feeding shaft 26 is fixed with a sealing plug 28. The sealing plug 28 has a frustum frame structure. The outer diameter of the bottom surface of the sealing plug 28 is equal to the diameter of the discharge port 32.

[0043] In use, the control system of the electric push rod 24 and servo motor 25 is programmed according to the feeding time, that is, the electric push rod 24 and servo motor 25 are triggered at regular intervals. When feeding is required, the switch of the electric push rod 24 is triggered, and the electric push rod 24 pulls the stopper plate 22 to lift quickly until the stopper plate 22 pulls the feed conveying shaft 26 to drive the sealing plug 28 to be inserted into the discharge port 32. At this time, the stopper plate 22 is pulled out from the opening of the dispensing cylinder 21, and the feed inside the plastic float tube 1 slides into the dispensing cylinder 21. Then, the switch of the electric push rod 24 is triggered to push the plug plate 22 into the opening of the dispensing cylinder 21. Then, the switch of the servo motor 25 is triggered. When the servo motor 25 drives the bolt feeding shaft 26 to rotate, the bolt feeding shaft 26 discharges the feed inside the dispensing cylinder 21 through the discharge port 32, thereby feeding the shrimp larvae in the feeding area. The plastic float tube 1 is used not only as a traditional float tube, but also as a feed storage mechanism and as a feed dispensing mechanism. That is, the plastic float tube 1 has multiple uses.

[0044] The operating procedure for this automatic feed dispensing equipment for shrimp larvae farming is as follows:

[0045] When two plastic floats 1 are joined end to end, the two connecting rings 2 at the ends of the two plastic floats 1 are brought together, and bolts 10 are used to pass through the bolt holes 9 on the surface of the two connecting rings 2 and then tightened to connect the two plastic floats 1. Two circular tube guide rings 11 with right-angled triangular cross-sections are fixed to the inner wall of the plastic float 1 beforehand, symmetrically distributed about the feeding port 17. The inner ring diameter of the guide ring 11 at the end closer to the feeding port 17 is larger than the inner ring diameter at the other end. Two partitions 12 are pushed into the two openings of the plastic float 1 respectively. After the partitions 12 are blocked and contacted by the corresponding guide rings 11, the screw 15 passes through the through hole 14 on the surface of the partition 12, and the nut 16 is screwed onto the screw 15 and tightened to firmly fix the partitions 12 on one side of the guide rings 11. The plastic floats 1 are laid on the sea surface, and two sets of connecting rings 2, two in each set, are fitted and fixed on the tube body of the plastic floats 1. Attach the floats 4 to both sides of the plastic float tube 1, so that both ends of the floats 4 are respectively attached to the assembly grooves 3 on the surfaces of the two connecting rings 2. At this time, the notches 29 at the ends of the two floats 4 are joined to form a circular groove. Screw the nuts 31 onto the connecting studs of the two assembled half studs 30 and lock them in place, pre-fixing the two floats 4 between the two connecting rings 2. Install the floats 4 at both ends of the plastic float tube 1 in this manner to ensure that the plastic float tube 1 floats stably on the sea surface. Twist the long-shank screw 6 through the side groove 5 on the side of the float 4 and screw it onto the surface of the assembly groove 3 to firmly fix the floats 4 and the connecting rings 2. Fix two reflective strips 7 arranged side by side on the outer ring surface of the floats 4, and wrap an LED light strip 8 around the outer ring surface of the connecting rings 2 to achieve warning and illumination functions. A dispensing cylinder 21 is inserted and fixed at the bottom of the plastic float tube 1, and a stopper plate 22 is inserted at the top of the dispensing cylinder 21. The stopper plate 22 is pulled by an electric push rod 24 fixed to the inner wall of the plastic float tube 1. Traction plates 23 are fixed on both sides of the stopper plate 22, and the bottom end of the piston rod of the electric push rod 24 is fixed to the top surface of the traction plate 23. A servo motor 25 is fixed on the top surface of the stopper plate 22. The top end of the bolt feeding shaft 26 passes through the stopper plate 22 and is connected to the power output end of the servo motor 25. The height of the bolt feeding shaft 26 is greater than the height of the dispensing cylinder 21. A discharge port 32 is opened on the bottom surface of the dispensing cylinder 21. A frustum frame structure sealing plug 28 with a bottom outer diameter equal to the diameter of the discharge port 32 is fixed at the bottom end of the bolt feeding shaft 26.

[0046] Feed is fed from the feeding port 17 into the storage space inside the plastic float 1, which is divided by two partitions 12. A threaded cap 18 is inserted and screwed into the threaded feeding port 17. The top surface of the cap 18 has multiple small holes 19 and is covered by a water-resistant and breathable surface layer 20. The control system of the electric push rod 24 and servo motor 25 is programmed according to the feeding time, triggering the switches of the electric push rod 24 and servo motor 25 at regular intervals. When feeding is needed, the switch of the electric push rod 24 is triggered, causing the electric push rod 24 to pull the stopper plate 22 up rapidly until the stopper plate 22 pulls the feed conveyor shaft 26, causing the sealing plug 28 to be inserted into the discharge port 32. At this time, the stopper plate 22 is pulled out from the opening of the dispensing cylinder 21, and the feed inside the plastic float 1 slides into the dispensing cylinder 21. Then, the switch of the electric push rod 24 is triggered again to push the stopper plate 22 down into the opening of the dispensing cylinder 21. Then the switch of servo motor 25 is triggered, servo motor 25 drives bolt feed shaft 26 to rotate, bolt feed shaft 26 discharges the feed inside the dispensing cylinder 21 through the discharge port 32 to feed the shrimp larvae in the feeding area.
