Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically: a fish fry separation device. Background Technology

[0002] Before stocking the pond, the fish fry need to be screened. On the one hand, this ensures the survival rate of the fish fry. On the other hand, the screened fish fry can be released and managed separately according to their size. This will prevent the fish fry from being preyed upon by the weak due to their different sizes, thus avoiding increased mortality and cost.

[0003] Chinese Patent CN211932089U discloses a fish fry separating device, including a frame, a bottom column, a nut, a support shaft, a collar, a partition, a fixing plate, and a handle. The collar is welded and fastened to the four corners on the left and right sides of the frame and is located at the top and bottom ends. The nut is threaded into the support shaft. The support shaft is threaded into the collar and is located at the four corners of the frame. The bottom column is heat-fused to the lower end of the support shaft. The handle is welded to the upper end of the left side of the frame. The fixing plates are arranged longitudinally at equal intervals at the upper end of the frame cavity. The partition connects the lower plane of the fixing plate to the upper plane of the bottom end of the frame cavity. This utility model provides a fish fry separating device, which facilitates the placement of fish fry from the fry pond into the frame, and the size of the fish fry is distinguished by the spacing between the partitions. At the same time, the right plane of the partition has a rounded corner, which facilitates the passage of fish fry on the right side to the cavity of the partition on the left side. However, the left side of the partition is a right angle, which makes it difficult for fish fry to pass through the cavity of the partition on the right side. The device has a simple structure and is easy to use.

[0004] However, although the above-mentioned patent can distinguish the size of fish fry by the size of the gap between the partitions, there are some problems in the process of use. For example, the adjustment of the gap between the partitions is not flexible enough and cannot meet the needs of separating fish fry of different sizes.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a fish fry separation device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A fish fry separating device includes: a fish-carrying plate, a baffle plate fixedly connected to the upper surface of the fish-carrying plate, two mounting frames fixedly connected to the inner wall of the baffle plate, an adjustment groove provided on the inner bottom wall and the inner top wall of each mounting frame, a set of adjustment blocks slidably connected to each adjustment groove, an adjustment rod fixedly connected to the side of the two sets of adjustment blocks that are close to each other, and a screw fixedly connected to the upper surface of the two sets of adjustment blocks, the top end of each screw penetrating through the mounting frame and extending to the top of the mounting frame, and a fixing nut threadedly connected to the outer surface of each screw.

Detailed Implementation

[0025] 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.

[0026] like Figures 1-5As shown, according to an embodiment of this utility model, a fish fry separating device is provided, comprising: a fish-carrying plate 1, a baffle plate 2 fixedly connected to the upper surface of the fish-carrying plate 1, two mounting frames 3 fixedly connected to the inner wall of the baffle plate 2, an adjustment groove 4 provided on the inner bottom wall and the inner top wall of each mounting frame 3, a set of adjustment blocks 5 slidably connected to each adjustment groove 4, and an adjustment rod 6 fixedly connected to the side of the two sets of adjustment blocks 5 that are close to each other, wherein a screw 7 is fixedly connected to the upper surface of the two sets of adjustment blocks 5, and the top end of each screw 7 penetrates through the mounting frame 3 and extends to the mounting frame 3. Above, each screw 7 has a fixed nut 8 threadedly connected to its outer surface. Through the above scheme, the adjusting block 5 slides in the adjusting groove 4, driving the adjusting rod 6 to move laterally, realizing stepless adjustment of the distance between the two sets of adjusting rods 6. This design breaks through the limitations of traditional fixed-distance seedling separation devices, and can flexibly adjust the channel width according to the body length of the fish fry, avoiding the fish fry getting stuck or escaping due to improper spacing. The threaded connection between the screw 7 and the fixed nut 8 forms a mechanical locking structure. When the target distance is adjusted, the fixed nut 8 is tightened, which can resist the impact of water flow and the external force generated by the swimming of fish fry, ensuring that the distance remains stable during the seedling separation process.

[0027] Continue to refer to Figures 1-5 Each adjusting rod 6 has a protective sleeve 9 fixedly connected to its outer surface. The protective sleeve 9 on the outer surface of the adjusting rod 6 is made of flexible rubber to prevent the fish fry from directly rubbing against the metal parts when passing through the separation channel, thereby reducing damage to the fish fry. Each screw 7 has an adjusting handle 10 fixedly connected to its top. Each adjusting handle 10 has an anti-slip sleeve 11 fixedly connected to its outer surface. The design of the adjusting handle 10 allows the operator to easily rotate the screw 7 to adjust the spacing without the need for additional tools. The anti-slip sleeve 11 increases the friction on the surface of the adjusting handle 10, ensuring that the operator can firmly hold the adjusting handle 10 even in a wet or oily working environment, preventing adjustment errors or safety accidents caused by slipping. Each screw 7 has a spring washer 12 fitted on its outer surface. Each spring washer 12 is located below the fixing nut 8 and can provide additional pressure when the fixing nut 8 is tightened, ensuring a tight connection between the fixing nut 8 and the screw 7 and preventing loosening due to vibration or water flow impact.

[0028] Continue to refer to Figures 1-5The inner wall of the enclosure 2 is fixedly connected to a fish attractant box 13. The outer surface of the fish attractant box 13 has multiple sets of equally spaced dispersing holes 14. The fish attractant box 13 is designed to attract fish fry into the seedling distribution channel. Through the setting of the dispersing holes 14, the fish fry can be more easily induced and then evenly distributed to various breeding areas through the seedling distribution channel. The back of the enclosure 2 has two fish release ports 15. The inner wall of each fish release port 15 is hinged to a gate 16. The outer surface of each gate 16 is fixedly connected to a pull plate 17. The pull plate 17 is designed to facilitate operation. The gate 16 is opened and closed manually to control the time and number of fish fry entering the separation device. A drain pipe 18 is fixedly connected to the outer surface of the enclosure 2. A sealing plug 19 is slidably connected inside the drain pipe 18. The sealing plug 19 can control the opening and closing of the drain pipe 18. When it is necessary to clean or drain the inside of the separation device, the staff can manually pull out the sealing plug 19 so that the water can be smoothly discharged from the outside of the device. When it is necessary to maintain a stable water level inside the device, the sealing plug 19 can be reinserted into the drain pipe 18.

[0029] In use, the operator rotates screw 7 by adjusting handle 10, causing adjusting block 5 to slide within adjusting groove 4, thus moving adjusting rod 6 laterally and changing the distance between the two sets of adjusting rods 6. After adjusting to the target distance, tighten fixing nut 8. Spring washer 12 generates elastic pressure under fixing nut 8 to prevent screw 7 from loosening due to vibration, ensuring the distance is fixed. Then, bait that fish fry like, such as plankton or feed powder, is placed into fish attractant box 13. The bait is evenly released into the baffle plate 2 through dispersing hole 14, forming a bait distribution area to attract fish fry to gather. Next, the group of fish fry to be separated is poured onto fish carrier plate 1. Baffle plate 2 forms a closed space to prevent fish fry from escaping. The bait released by fish attractant box 13 attracts fish fry to gather near adjusting rod 6, facilitating separation. The width of the separation channel is determined by the distance between adjusting rod 6 and can be adjusted according to the size of the fish fry, thus achieving flexible use.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
