Description

A precision quantitative feeding device for recirculating aquaculture of shrimp. Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a precise quantitative feeding device for recirculating aquaculture of shrimp. Background Technology

[0002] Recirculating aquaculture systems (RAS) for shrimp farming are an intensive aquaculture model that continuously purifies and reuses aquaculture water through a water treatment system. In RAS for shrimp farming, the accuracy of feed feeding directly affects farming costs, shrimp growth efficiency, and water quality stability. Currently, manual feeding is commonly used. However, manual feeding relies heavily on the experience of workers to grasp the feed, which can lead to significant errors. This can result in overfeeding, causing feed waste, uneaten feed polluting the water, and increasing the water treatment load. Alternatively, underfeeding can hinder normal shrimp growth, making it difficult to accurately control the amount of feed given and thus affecting shrimp growth efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a precise quantitative feeding device for recirculating aquaculture of shrimp, which solves the technical problems mentioned in the background section.

Detailed Implementation

[0020] 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.

[0021] In recirculating aquaculture systems (RAS) shrimp farming, the accuracy of feed delivery directly impacts farming costs, shrimp growth efficiency, and water quality stability. Currently, manual feeding is commonly used. However, manual feeding relies heavily on the experience of workers to grasp the feed, which can lead to significant errors. This can result in overfeeding, causing feed waste, uneaten feed polluting the water, and increasing the load on water treatment facilities. Alternatively, underfeeding can hinder normal shrimp growth, making it difficult to precisely control the amount of feed administered and ultimately impacting shrimp growth efficiency.

[0022] To address the shortcomings of manual shrimp feeding, please refer to Figures 1-5. This invention provides a precise quantitative feeding device for recirculating aquaculture of shrimp, which can achieve precise quantitative feeding in a short time, effectively avoiding errors in manual feeding and promoting the healthy growth of shrimp. The feeding device is based on a feeding cylinder 1. A pair of adapter seats 2 are installed on both sides of the bottom of the feeding cylinder 1. A rotating shaft 3 is rotatably mounted inside the adapter seat 2. A sealing plate 4 is fixedly sleeved on the outside of the rotating shaft 3. The two sealing plates 4 can control the opening and closing of the lower end of the feeding cylinder 1. Torsion springs 5 ​​are sleeved on both ends of the rotating shaft 3, and the two ends of the torsion springs 5 ​​are respectively fixedly mounted on the adapter seat 2 and the sealing plate 4. A steel wire 6 is installed at the end of the sealing plate 4. An opening and closing ring 7 is slidably mounted on the outside of the feeding cylinder 1. The upper end of the steel wire 6 is fixedly mounted on the bottom of the opening and closing ring 7. A fixed rod 8 is slidably mounted inside the feeding cylinder 1. A limiting member 9 is provided at the upper end of the feeding cylinder 1 to fix the fixed rod 8. A positioning ring 10 is fixedly sleeved on the outside of the feeding cylinder 1, positioned above the opening and closing ring 7. A handle 11 is provided on the outside of both the opening and closing ring 7 and the positioning ring 10. When picking up material, the handle 11 is used to... Slide the feed rod 8 down to the designated height, and fix it with the limiting member 9. Hold the two handles 11 to drive the opening and closing ring 7 to slide upward. The upward sliding of the opening and closing ring 7 can pull the sealing plate 4 open through the steel wire 6. At this time, the torsion spring 5 deforms. Then insert the feeding cylinder 1 into the feed bag. The feed can enter the feeding cylinder 1 through the opening of the feeding cylinder 1. The feed rod 8 can limit the amount of feed entering the feeding cylinder 1, keeping the feed at the height of the feed rod 8. Then release the handles 11, and the sealing plate 4 can be closed by the torque of the torsion spring 5. The measured amount of feed can be taken out. After taking it out, move the feeding cylinder 1 to the breeding pond. Hold the handles 11 again to control the sealing plate 4 to open again. The feed in the feeding cylinder 1 can fall into the breeding pond. This realizes quantitative feeding in a short time, which is conducive to the precise control of the amount of feed and is beneficial to the healthy growth of shrimp.

[0023] Since shrimp require different amounts of feed at different growth stages, a bracket 91 is fixedly installed on one side of the top of the feeding cylinder 1 to facilitate adjustment of the feed grabbing amount. A sliding rod 92 is slidably connected inside the bracket 91, and an insert block 93 is fixedly connected to the end of the sliding rod 92. A telescopic spring 94 is sleeved on the outside of the sliding rod 92 to compress and extend the insert block 93. The two ends of the telescopic spring 94 are fixedly installed on the insert block 93 and the bracket 91, respectively. Multiple longitudinally evenly spaced openings are provided on the outside of the feed rod 8. The slot 95 has a plug 93 extending into it. When adjusting the feed amount, the slide bar 92 is pulled to move the plug 93 out of the slot 95. At this time, the telescopic spring 94 deforms and slides the fixed feed rod 8 up and down, which can adjust the height of the fixed feed rod 8 and thus adjust the amount of feed picked up. After the fixed feed rod 8 is adjusted to the specified height, the slide bar 92 is released, and the plug 93 can enter the corresponding slot 95 through the elastic force of the telescopic spring 94 to fix the fixed feed rod 8, so that the feed cylinder 1 can be used.

[0024] To facilitate observation of the height of the feed rod 8 inside the feed cylinder 1, the feed cylinder 1 is made of transparent acrylic material, and a scale 12 is provided on the outer surface of the feed cylinder 1. By observing the feed rod 8 and the scale 12, the amount of feed picked up can be better controlled.

[0025] Example 2

[0026] Since the sealing plate 4 needs to be inserted into the feed bag when taking feed, as shown in Figure 5, the sealing plate 4 is provided with a beveled surface 401 on the side away from the wire 6. The beveled surface 401 is more helpful for the sealing plate 4 to enter the feed than the traditional flat surface, so that the feed can be grasped more easily.

[0027] Furthermore, a conical annular surface 101 is provided at the lower end of the feeding cylinder 1. When the sealing plate 4 is closed, it can squeeze the feed into the feeding cylinder 1 along the conical annular surface 101, which helps the sealing plate 4 to close smoothly.
