Description

Technical Field

[0001] This utility model relates to the field of white shrimp farming technology, specifically to a convenient-to-operate harvesting device for white shrimp farming. Background Technology

[0002] The white shrimp, also known as the white shrimp, small white shrimp, five-whiskered shrimp, green shrimp, and spring shrimp, is an arthropod belonging to the genus *Euphorbia* in the family Palaemonidae of the order Decapoda. Adults are 50-90 mm in length; their bodies are transparent with slight blue or red spots; their rostrum is laterally compressed; their carapace has small antennal spines and larger gill spines and gill grooves. In aquaculture, white shrimp often require specialized equipment for rearing to ensure optimal farming results.

[0003] Existing shrimp farming equipment has the disadvantage of being inconvenient for harvesting, which requires a lot of time for workers to harvest shrimp, increases the labor intensity of workers, is inconvenient to use, and reduces the efficiency and effectiveness of the farming equipment.

[0004] As disclosed in Chinese Patent CN215684321U, a shrimp farming device for easy harvesting includes a farming box, a telescopic mechanism, and a harvesting mechanism. The telescopic mechanism is located above the farming box, and the harvesting mechanism is located below the telescopic mechanism. The harvesting mechanism includes a filter plate. A fixing block is fixedly connected to the left side of the top of the filter plate, and an electric push rod is fixedly connected to the right side of the fixing block. A waterproof telescopic cover is fixedly connected to the right side of the fixing block. A fixing push plate is fixedly connected to the right end of the electric push rod, and sliding blocks are fixedly connected to both the left and right sides of the filter plate.

[0005] When catching shrimp, the device raises the height of the filter plate, causing the shrimp to rise and leave the water surface. This catching method has a limited scope of application; it is suitable for small breeding boxes but not for large breeding ponds. Its catching efficiency is low and the operation is cumbersome.

[0006] To address these issues, we propose an easy-to-operate harvesting device for white shrimp farming. Summary of the Invention

[0023] 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.

[0024] See also Figures 1-4 This utility model provides a technical solution:

[0025] Example 1: A user-friendly harvesting device for farming white shrimp includes a fixed frame 1 and a fixed plate 2. The fixed plate 2 is fixedly installed on one side of the outer surface of the fixed frame 1. A circular hole 201 is passed through the middle of the upper surface of the fixed plate 2. A cylinder 202 is fixedly installed on the upper surface of the fixed plate 2. The output end of the cylinder 202 is connected to a telescopic column 203 that passes through the circular hole 201. A top plate 204 is fixedly connected to the bottom surface of the telescopic column 203. An adjustment mechanism is provided on one side of the upper surface of the fixed frame 1. A harvesting mechanism is provided on the bottom surface of the top plate 204. A collection mechanism is provided below the top plate 204.

[0026] The adjustment mechanism includes a winding unit and a moving unit. The winding unit includes a motor mounting base 3 fixedly installed on one side of the outer surface of the fixed frame 1. A drive motor 301 is fixedly installed on the upper surface of the motor mounting base 3. The output end of the drive motor 301 is connected to a transmission shaft 302. A winding reel 303 is fixedly connected to one end of the transmission shaft 302. A take-up rope 306 is connected to the output end of the take-up reel 303. A first convex seat 304 is fixedly installed on one side of the upper surface of the fixed frame 1. A first roller 305 is rotatably installed on one side of the inner wall of the first convex seat 304. The upper part of the outer surface of the first roller 305 is in contact with the outer surface of the take-up rope 306. A connecting cylinder 307 is fixedly connected to one end of the take-up rope 306.

[0027] The moving unit includes a second convex seat 311 fixedly installed on the upper surface of the top plate 204. A second roller 312 is rotatably installed on one side of the inner wall of the second convex seat 311. A limiting groove 308 passes through the outer side of the upper surface of the top plate 204. A baffle plate 309 is slidably connected to the inner wall of the limiting groove 308. A connecting rope 310 is fixedly connected to the upper surface of the baffle plate 309. The outer surface of the connecting rope 310 contacts the lower part of the outer surface of the second roller 312, and the upper end of the connecting rope 310 is fixedly connected to the bottom surface of the connecting cylinder 307. The limiting groove 308 is distributed in a ring on the four sides of the upper surface of the top plate 204. One side of the outer surface of the baffle plate 309 is slidably connected to the outer surface of the first nylon mesh 401. The connecting rope 310 is attached to the lower part of the outer surface of the second roller 312 and fixedly connected to the bottom surface of the connecting cylinder 307.

[0028] In this embodiment: when harvesting white shrimp, the power to the drive motor 301 is turned on and the cylinder 202 is operated. The output end of the cylinder 202 pushes the telescopic column 203 to move downward. The telescopic column 203 then drives the top plate 204 to move downward, thereby pushing the harvesting mechanism downward and submerging it in the water. As the top plate 204 descends, it drives the connecting rope 310 and the connecting cylinder 307 to descend. At the same time, the drive motor 301 rotates, driving the transmission shaft 302 to rotate, causing the line to be released in the reel 303, realizing the movement of the pull rope 306. Once the top plate 204 is submerged in the water... Once in the water, the drive motor 301 reverses, causing the winding reel 303 to reverse and move the winding rope 306 upward. The winding rope 306 pulls the connecting cylinder 307, which in turn pulls the connecting rope 310 to rotate on the outer surface of the second roller 312, lifting the shield 309 upward. This allows the shield 309 to slide and rise within the inner wall of the limiting groove 308, facilitating the entry of white shrimp from the first nylon net surface 401 on one side of the outer surface of the shield 309 for harvesting. After harvesting, the shield 309 moves in the opposite direction and descends, shielding the first nylon net surface 401.

[0029] Example 2: Based on Example 1, the fishing mechanism includes fixed posts 4 fixedly connected to the four corners of the bottom surface of the top plate 204. A U-shaped plate 406 is fixedly connected to the bottom surface of the fixed posts 4. A counterweight post 407 is fixedly connected to the bottom surface of the U-shaped plate 406. A first nylon mesh 401 is fixedly connected to one side of the outer surface of the fixed posts 4. A hole is penetrating one side of the outer surface of the first nylon mesh 401, and a first conical cylinder 402 is fixedly connected to the inner wall of the hole. A first connecting rod 404 is fixedly connected to one end surface of the first conical cylinder 402. A first escape-proof cover 405 is fixedly connected to one end surface of the first connecting rod 404. A first drainage hole 403 is penetrating the outer surface of the first conical cylinder 402 at equal intervals.

[0030] The No. 1 nylon mesh 401 is distributed in a ring below the top plate 204. The No. 1 conical cylinder 402 is symmetrically distributed on the upper and lower parts of one side of the outer surface of the No. 1 nylon mesh 401. The diameter of the No. 1 escape cover 405 is larger than the diameter of one end of the No. 1 conical cylinder 402.

[0031] In this embodiment: After the white shrimp enters the first conical tube 402 fixedly installed on one side of the outer surface of the first nylon mesh 401, it swims out from the other end of the first conical tube 402. The first escape cover 405 connected to the first conical tube 402 by the first connecting rod 404 at the other end of the first conical tube 402 prevents the white shrimp from swimming back and escaping after swimming out of the first conical tube 402. Multiple first conical tubes 402 are installed on the outer surface of multiple distributed first nylon meshes 401 to improve the harvesting efficiency of white shrimp.

[0032] Example 3: Based on Example 2, the collection mechanism includes a second nylon mesh 5 fixedly connected to the inner wall of the U-shaped plate 406. A hole is penetrating through the middle of the upper surface of the second nylon mesh 5, and a second conical cylinder 501 is fixedly connected to the inner wall of the hole. A second drainage hole 502 is penetrating through the outer surface of the second conical cylinder 501 at equal intervals. A second connecting rod 503 is fixedly connected to the bottom surface of the second conical cylinder 501. A second anti-escape cover 504 is fixedly connected to the bottom surface of the second connecting rod 503. A collection net box 505 is snapped onto the bottom surface of the U-shaped plate 406.

[0033] In this embodiment, the bait is placed in the collection net box 505. The white shrimp that enter the first nylon net 401 continue to swim into the second conical tube 501. After passing through the second conical tube 501, they swim out from the second escape cover 504 at the other end of the second conical tube 501 and enter the collection net box 505, thus completing the capture and collection of the white shrimp. The collection net box 505 is snapped to the bottom of the U-shaped plate 406. After the capture is completed, the collection net box 505 can be disassembled to collect the captured white shrimp.
