[0022] 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.

[0023] This utility model provides, for example Figure 1-5The aquaculture harvesting device shown includes a harvesting net 1 and a fixing frame 2. The fixing frame 2 has positioning grooves 4. Fixing strips 3 are installed on the top of the harvesting net 1, and the fixing strips 3 are inserted into the positioning grooves 4. There are four positioning grooves 4 and four fixing strips 3. A limiting frame 5 for pressing the fixing strips 3 is provided on the top of the fixing frame 2. A first fixing plate 6 and a second fixing plate 8 are installed on the two side walls of the harvesting net 1. A limiting component 7 for connecting the first fixing plate 6 and the second fixing plate 8 is installed on the first fixing plate 6. The limiting component 7 includes a fixing side plate 701 located on the fixing bottom plate. On one side wall of the fixed base plate 701, guide shafts 702 are respectively installed on one side wall. An L-shaped limiting plate 703 is slidably engaged on the guide shaft 702. A compression spring 704 is provided on the side wall of the guide shaft 702. During fishing, the fixed base plate 6 and the fixed base plate 8 are first placed together. The compression spring 704 drives the L-shaped limiting plate 703 to move, allowing the L-shaped limiting plate 703 to limit the fixed base plate 8, thus connecting the fixed base plate 6 and the fixed base plate 8. The opening at the bottom of the fishing net 1 can be closed through the fixed base plate 6 and the fixed base plate 8. Then, the aquatic products are caught through the fishing net 1. After harvesting, by pulling the L-shaped limiting plate 703, the L-shaped limiting plate 703 is no longer limiting the fixed base plate 2 8, thereby allowing the fixed base plate 1 6 and the fixed base plate 2 8 to separate. This allows the opening at the bottom of the fishing net 1 to open, enabling the aquatic products to be poured directly from the bottom of the fishing net 1, which improves the ease of operation of the fishing device. Threaded rods 9 are installed on the top outer wall of the fixed frame 2. The limiting frame 5 and the threaded rods 9 are slidably engaged. A locking nut 10 is connected to the threaded surface of the threaded rod 9. By tightening the locking nut 10, the limiting frame 5 is pressed against the fixed strip 3, allowing the fishing net to be harvested. When catching aquatic products of different sizes, first remove the nuts on the four threaded rods 9, then remove the limiting frame 5 from the top of the fixed frame 2, then pull the fixing strip 3 out from the inside of the positioning groove 4, and pass the fixing strip 3 on the different specifications of the fishing net cover 1 through the positioning groove 4, then fold it so that part of the fixing strip 3 can be placed on the top of the fixed frame 2, then press the limiting frame 5 against the fixing strip 3 on the fixed frame 2, and then install the locking nut 10 on the threaded rods 9 and tighten it, which can drive the limiting frame 5 to press and fix the fixing strip 3. Therefore, this device can easily replace the fishing net cover 1 with different mesh sizes, making it convenient to catch aquatic products of different sizes.

[0024] In this embodiment, fixing rods 14 are respectively installed on one side wall of fixing base plate 2 8. When fixing base plate 1 6 and fixing base plate 2 8 are attached together, fixing rods 14 can be engaged with fixing base plate 1 6, which helps to improve the stability of fixing base plate 1 6 and fixing base plate 2 8 after connection.

[0025] In this embodiment, a guide crossbar 11 is installed on the top outer wall of the limiting frame 5. A guide sleeve 12 is slidably engaged on the guide crossbar 11. A handrail 15 is installed on one side wall of the guide sleeve 12. A locking bolt 13 is connected to the guide sleeve 12. The locking bolt 13 passes through the guide sleeve 12 and engages with the guide crossbar 11. By turning the locking bolt 13, it can be disengaged from the positioning hole on the guide crossbar 11. Then the guide sleeve 12 can be slid, and the length of the fishing device can be adjusted, thereby adjusting the fishing range of the device.

[0026] In this embodiment, anti-slip grooves 16 are respectively provided on the bottom outer wall of the limiting frame 5. The anti-slip grooves 16 make the limiting frame 5 more stable when pressing the fixing strip 3.

[0027] Working principle of this utility model: This utility model is an aquaculture harvesting device. First, the fixed base plate 6 and the fixed base plate 8 are attached together. The compression spring 704 can drive the L-shaped limiting plate 703 to move. The L-shaped limiting plate 703 can limit the fixed base plate 8, thereby connecting the fixed base plate 6 and the fixed base plate 8, and then closing the opening at the bottom of the harvesting net 1. Then, aquatic products can be harvested through the harvesting net 1. By pulling the L-shaped limiting plate 703, it can no longer limit the fixed base plate 8. Then, the fixed base plate 6 and the fixed base plate 8 can be separated, so that the opening at the bottom of the harvesting net 1 can be opened, so that the aquatic products can be poured directly from the bottom of the harvesting net 1, making the operation of this harvesting device more convenient.

[0028] When it is necessary to catch aquatic products of different sizes, remove the nuts on the four threaded rods 9 in sequence. Then, the limiting frame 5 can be removed from the top of the fixing frame 2 so that it no longer presses against the fixing strip 3. Next, the fixing strip 3 can be pulled out from the inside of the positioning groove 4. Then, the fixing strip 3 on the different specifications of the fishing net 1 is passed through the positioning groove 4 and folded over to be placed on the top of the fixing frame 2. Then, the limiting frame 5 presses against the fixing strip 3 on the fixing frame 2. Then, the locking nuts 10 are installed on the threaded rods 9 in sequence and tightened, so that the limiting frame 5 can fix the fixing strip 3. This device can easily and quickly replace the fishing net 1 with different mesh sizes, which is beneficial for catching aquatic products of different sizes.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
