Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to an automatic feeding and precise quantitative device for Litopenaeus vannamei ponds. Background Technology

[0002] Litopenaeus vannamei, also known as the whiteleg shrimp, is one of the most important farmed shrimp species globally due to its rapid growth, strong adaptability, and delicious meat. As a major producer and consumer of Litopenaeus vannamei, my country has seen its annual production steadily increase and its farming scale expand, securing a significant position in the aquaculture industry. Scientific and efficient farming methods are crucial for ensuring the yield and quality of Litopenaeus vannamei, and precise feeding, as a core aspect of the farming process, directly impacts farming efficiency and the ecological environment.

[0003] Currently, feeding methods in Litopenaeus vannamei ponds mostly rely on manual, timed feeding or simple mechanical devices, making precise quantitative feeding difficult. Manual feeding is not only labor-intensive and inefficient, but the amount of feed also depends entirely on the experience of the farmer, easily leading to overfeeding or underfeeding. Overfeeding results in feed waste, increased farming costs, and the decomposition of leftover feed in the water can pollute the water and induce disease; underfeeding, on the other hand, affects shrimp growth and reduces yield. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 An automatic feeding and precise metering device for Litopenaeus vannamei shrimp farming ponds includes a feed storage bin 1. A feed distribution pipe 2 is bolted to the top of the feed storage bin 1. A conveying pipe 3 is fixedly connected to the top of the feed distribution pipe 2. An auger rod 4 is rotatably connected inside the conveying pipe 3, and a feeding hopper 5 is fixedly connected to the outer circumference of the conveying pipe 3. A connecting block 6 is fixedly connected to the side wall of the feed storage bin 1. A galvanized steel pipe 7 is bolted to the outer surface of the connecting block 6. Side plates 8 are fixedly connected to both ends of the galvanized steel pipe 7. An electric push rod 9 is rotatably connected to the outer surface of the side plate 8. A connecting rod 10 is rotatably connected to the telescopic end of the electric push rod 9. A cover plate 11 is hinged to the bottom of the feed storage bin 1, and ear blocks 12 are fixedly connected to the outer surface of the cover plate 11. A protruding post 13 is fixedly connected to the outer surface of the side plate 8. A first movable plate 14 is fixedly connected to one end of the protruding post 13. A square tube 15 is fixedly connected to the back of the first movable plate 14. A second movable plate 16 is fixedly connected to one end of the square tube 15. Two rollers 17 are rotatably connected between the first movable plate 14 and the second movable plate 16. A transmission rod 18 is fixedly connected to the shaft end of one of the rollers 17. A sprocket 19 is fixedly connected to the outer wall of the transmission rod 18. A chain 20 is meshed with the sprocket 19. A sprocket 21 is meshed with the chain 20. A first motor 22 is connected to the center of the end face of the second sprocket 21 through a shaft. A second motor 23 is connected to one end of the conveying pipe 3. The outer surface of the roller 17 rolls in contact with the ground rail 24.

[0017] Specifically, the bottom of the feeding hopper 5 is connected to the conveying pipe 3, and several feeding branch pipes 2 are fixedly connected at equal intervals on the outer circumference of the conveying pipe 3.

[0018] Specifically, the output shaft of the second motor 23 is fixedly connected to the auger rod 4, the number of bait storage bins 1 is the same as that of the feeding branch pipe 2, and a material level sensor 25 is installed on the outer wall of the bait storage bin 1 closest to the outermost side of the conveying pipe 3.

[0019] The advantage is that by setting the feeding hopper 5 close to the side of the aquaculture pond, feed can be manually fed into the feeding hopper 5 during the aquaculture process. Then, by starting the second motor 23, the auger rod 4 rotates. Since the bottom end of the feeding hopper 5 is connected to the conveying pipe 3, the feed inside the feeding hopper 5 can enter the conveying pipe 3. As the auger rod 4 rotates, the feed is conveyed to the feed distribution pipe 2. The bottom end of the feed distribution pipe 2 is connected to the feed storage bin 1, thus storing the feed in each of the feed storage bins 1. It is worth noting that during this process, the feed distribution pipe 2 closest to the feeding hopper 5 will receive feed first. Once the feed storage bin 1 connected to the bottom end of the feed distribution pipe 2 is full, the auger rod 4 will then carry the feed into the next feed distribution pipe 2. A level sensor 25 (e.g., ...) is installed on the outer wall of one of the feed storage bins 1 located at the outermost edge of the conveying pipe 3. Figure 2 As shown in the diagram, when the level sensor 25 detects that the feed storage bin 1 connected to it is full of feed, it sends a signal to the control cabinet 30, and the control cabinet 30 stops the second motor 23. This ensures that each feed storage bin 1 is full of feed, which prepares the groundwork for subsequent quantitative feeding.

[0020] Specifically, the outer surface of the connecting rod 10 is interspersed with several equally spaced lugs 12, and both ends of the connecting rod 10 are rotatably connected to electric push rods 9. An arc-shaped groove 26 is provided on the outer wall of the side plate 8.

[0021] The advantage is that by activating the electric push rod 9, its telescopic end drives the connecting rod 10 to move under the limiting and guiding action of the arc groove 26. In this way, the connecting rod 10 drives several ear blocks 12 to move synchronously. The ear blocks 12 drive the cover plate 11 to rotate around the axis that is hinged to the bottom of the bait storage chamber 1. In this way, the bottom of the bait storage chamber 1 opens, so that the bait inside can be discharged. The overall structure can realize automatic feeding. Furthermore, by controlling the telescopic amount of the electric push rod 9, the opening and closing angle of the cover plate 11 can be controlled, thereby achieving the amount of bait to be fed at one time. This process can be controlled by the control cabinet 30 to control the start and stop time and telescopic amount of the electric push rod 9.

[0022] Specifically, the first motor 22 is installed on the outer surface of one of the second movable plates 16, and the shaft end of the roller 17 is fixedly connected to the third sprocket 27, which is engaged with the second chain 28.

[0023] Specifically, the ground rail 24 is installed on the side of the breeding pond, and a support rod 29 is fixedly connected to the top surface of one of the moving plates 14. A control cabinet 30 is installed on the top of the support rod 29.

[0024] The advantage is that during the feeding process, the first motor 22 is started to drive the second sprocket 21 to rotate. The second sprocket 21 drives the first chain 20, the first chain 20 drives the first sprocket 19, the first sprocket 19 drives the transmission rod 18, and the transmission rod 18 drives a roller 17 connected to it to rotate. Since the two rollers 17 are connected by two third sprockets 27 and the second chain 28, the two sets of rollers 17 can rotate synchronously on the ground rail 24. This can drive the entire device to move above the breeding pond, thereby enabling comprehensive and even feeding of Litopenaeus vannamei in the breeding pond. Sliding rails can also be installed on the ground rail 24 to supply power to the first motor 22, the second motor 23, and the control cabinet 30 using existing technology.

[0025] In operation, firstly, the bait is manually placed into the feeding hopper 5. The second motor 23 is then started, driving the auger rod 4 to rotate. The bait enters the conveying pipe 3 from the feeding hopper 5, and is then transported to various feeding branch pipes 2, finally being stored in the bait storage bin 1. When the level sensor 25 on the outermost bait storage bin 1 of the conveying pipe 3 detects that the bin is full, it sends a signal to the control cabinet 30 to stop the second motor 23. Secondly, the electric push rod 9 is started, and its telescopic end drives the connecting rod 10 to move under the limiting guide of the arc-shaped groove 26. The connecting rod 10 drives the lug 12, and the lug 1... 2. The cover plate 11 is rotated to open the bottom of the feed storage chamber 1. The start and stop time and extension and retraction of the electric push rod 9 are controlled by the control cabinet 30 to control the opening and closing angle of the cover plate 11, so as to control the amount of feed. Finally, the first motor 22 is started to drive the second sprocket 21 to rotate. Through the first chain 20, the first sprocket 19, and the transmission rod 18, a roller 17 is rotated. Then, with the help of the two third sprockets 27 and the second chain 28, the two sets of rollers 17 are rotated synchronously, driving the entire device to move on the ground rail 24 to feed the Litopenaeus vannamei shrimp in the breeding pond evenly.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
