Abstract
Description
Technical Field
[0001] The present application relates to the field of crayfish seedling release, and in particular to a crayfish seedling release device. Background Art
[0002] Crayfish larvae refer to crayfish that have reached a certain growth stage after hatching. Crayfish (also known as Procambarus clarkii) are a popular aquatic product. After being raised, young crayfish (often called shrimp fry) need to be released into aquaculture waters to facilitate their growth and reproduction in their new environment.
[0003] Since crayfish are generally released artificially, containers with crayfish fry are placed on boats, and the fry are released simultaneously along the breeding pond. However, it is inconvenient for people to control the release rate and range when dumping the fry on the boat. When dealing with areas of different sizes in the breeding pond, it may cause too many or too few crayfish when releasing fry, and the crayfish may be too concentrated when releasing fry, resulting in a smaller overall activity space, which in turn affects the overall living environment of the crayfish and has a certain impact on the subsequent growth of the crayfish.
[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect in that it is inconvenient to control the release range of crayfish when releasing them. Therefore, a crayfish release device is proposed to solve the above problem. Utility Model Content

[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The embodiment of the present application discloses a crayfish seedling releasing device. Figure 1-3 The top of the lifting frame 1 is provided with a fixed frame 2, and the bottom of the lifting frame 1 is provided with a fixed frame 4.
[0020] By placing the shrimp fry in the placement box 2, the hull 1 is moved along the breeding pond, the movable guide frame 6 is moved along the inside of the hollow guide frame 5, the overall seedling release range of the hollow guide frame 5 and the movable guide frame 6 is adjusted, and at the same time, the fastening bolt 10 is rotated to cancel the limit on the guide support plate 9, so that the guide support plate 9 rotates along the outer surface of the threaded sleeve 8 to maintain a certain inclination angle, and the fastening bolt 10 is rotated to fix the guide support plate 9 on the upper surface of the hollow guide frame 5 at different angles, so that the shrimp fry are guided and moved along multiple guide support plates 9 at different angles, and then released into the breeding pond along multiple seedling release ports 7, which reflects the uniform release effect of the shrimp fry in different numbers of seedling release ports 7.
[0021] Reference Figure 2 and Figure 3The spacing adjustment mechanism includes a fixed plate 11, which is symmetrically welded on both sides of the bottom end of the hollow guide frame 5. A bidirectional screw rod 12 is rotatably installed between the two fixed plates 11, and a fixed rod 13 is welded between the two fixed plates 11 at the back of the bidirectional screw rod 12. A movable part 14 is symmetrically installed on the outer surfaces of the bidirectional screw rod 12 and the fixed rod 13. One side edge of the movable part 14 extends to the lower bottom surface of the movable guide frame 6 and is symmetrically welded with a connecting rod 15. A threaded hole is provided on one side edge of the movable part 14, and external threads with opposite thread patterns are respectively provided on both sides of the outer surface of the bidirectional screw rod 12. The outer surface of the bidirectional screw rod 12 is located inside the threaded hole, and a through hole is provided on one side of the movable part 14 at the back of the threaded hole. The outer diameter of the fixed rod 13 is smaller than the inner diameter of the through hole, and one side of the outer surface of the fixed rod 13 is located inside the through hole.
[0022] By rotating the bidirectional screw rod 12, the movable part 14 is driven to move along the outer surface of the fixed rod 13, so that the fixed rod 13 guides and supports the movable part 14, keeping the movable part 14 in a stable active state, so that the seedling release port 7 moves synchronously with the movable part 14 under the connection of the connecting rod 15, and then the movable guide frame 6 moves along the inside of the hollow guide frame 5, reflecting the spacing adjustment effect of the two movable guide frames 6.
[0023] Reference Figure 1 and Figure 2 The discharge pipe mouth 3 is provided with a fixed long groove on the upper surface, and a limit plug 16 is inserted in the fixed long groove inside the discharge pipe mouth 3. The limit plug 16 is movably abutted against the bottom end of the inner wall of the discharge pipe mouth 3. By making the limit plug 16 move downward along the fixed long groove at the top of the discharge pipe mouth 3, the limit plug 16 limits the discharge pipe mouth 3, thereby controlling the opening and closing of the discharge pipe mouth 3, reflecting the release control effect of the limit plug 16 on the shrimp seedlings.
[0024] The implementation principle of the crayfish seedling releasing device of the embodiment of the present application is as follows: by placing the shrimp seedlings in the placing box 2, the hull 1 is made to move along the breeding pond, the two-way screw rod 12 is rotated to drive the movable part 14 to move along the outer surface of the fixed rod 13, so that the fixed rod 13 guides and supports the movable part 14, keeps the movable part 14 in a stable movable state, and makes the seedling releasing port 7 move synchronously with the movable part 14 under the connection of the connecting rod 15, thereby making the movable guide frame 6 move along the inside of the hollow guide frame 5, adjusting the overall seedling releasing range of the hollow guide frame 5 and the movable guide frame 6, and at the same time rotating the fastening bolt 10 to cancel the limit of the guide support plate 9, The guide support plate 9 is rotated along the outer surface of the threaded sleeve 8 to maintain a certain inclination angle, and the fastening bolt 10 is rotated to move along the inside of the threaded sleeve 8, so that the threaded sleeve 8 fixes the guide support plate 9 on the upper surface of the hollow guide frame 5 at different angles, so that the shrimp seedlings are guided along the guide support plates 9 at multiple angles, and then released into the breeding pond along multiple seedling release ports 7, so that the shrimp seedlings are evenly released in the breeding pond; compared with the existing technology, this solution has the effect of facilitating the adjustment of the shrimp seedling release range, improving the uniformity of shrimp seedling release, solving the problem of excessive concentration of shrimp seedlings during release, and improving the overall utilization rate of the breeding pond space.
