Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a fishing and retrieval device for aquaculture. Background Technology

[0002] In existing technologies, after fish are raised and nurtured in aquaculture ponds, a retrieval device is needed to retrieve the fry. A search revealed that a Chinese patent (application number: 202420249706.0) describes a retrieval device for ecological aquaculture. By controlling the downward movement of the threaded rod extension, the bottom of the retrieval net is lowered to a certain depth. The position of the bottom of the retrieval net can be adjusted according to the depth of algae or the location of impurities in the water, thereby retrieval of algae and impurities at different depths. Furthermore, the vibration of the retrieval net removes a small amount of impurities, thus aiding in cleaning the net.

[0003] However, the aforementioned patent requires that the seedlings be manually removed from the retrieval net after being retrieved before the net can be reused. This back-and-forth process is very time-consuming and affects the efficiency of seedling retrieval. Therefore, improvements are needed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a fishing and harvesting device for aquaculture, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A salvage device for aquaculture includes a hull, with a rotating salvage structure installed on the top of both sides of the hull. The salvage structure includes a rotating frame installed on the top of the hull side, and a salvage net is installed at the end of the rotating frame away from the hull side.

[0007] Specifically, in this utility model, the rotating frame includes an L-shaped rotating rod, with a horizontal handle fixed to the upper end of the vertical rod, the waist of the horizontal rod being rotatably mounted on the top of the side of the boat, and the free end of the horizontal rod being fixed to the salvage net.

[0008] To enable the retrieval net to rotate, two opposing fixed plates are fixed on the side of the hull, and a round shaft is fixed between the two fixed plates near their upper ends. A round hole is opened on the crossbar of the rotating rod, and the round hole is rotatably engaged with the round shaft.

[0009] Specifically, in this utility model, the salvage net includes a U-shaped enclosure, with the open end of the enclosure facing the free end of the horizontal bar of the rotating rod. An installation strip is fixed between the bottom sides of the open end and the closed end of the enclosure, and several equally spaced adjustable baffles are installed between the tops of the two installation strips.

[0010] To secure the salvage net, an ear plate is fixed at the top center of the mounting strip near the rotating rod, and the free end of the crossbar of the rotating rod is fixed to the side of the ear plate.

[0011] In order to adjust the spacing of the stop bar, the mounting strip has several equally spaced screw holes along its length. Near the end of the stop bar, there is an insertion hole that is vertically opposite to the screw holes. A bolt is disassembled in the insertion hole, and the lower end of the bolt is threaded into the screw hole.

[0012] Compared with the prior art, this utility model has the following advantages: by lifting the rotating rod upward, the fishing net can be extended into the aquaculture pond to catch fish; by pressing down the rotating rod, the closed end of the fishing net is tilted upward, allowing the fish to slide directly into the cabin of the boat, making it more convenient to catch fish and saving the need to manually take the fish out of the fishing net and put them into the cabin.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figure 1 As shown, this utility model provides a salvage device for aquaculture, including a hull 1, with a rotating salvage structure installed on the top of both sides of the hull 1. The salvage structure includes a rotating frame installed on the top of the side of the hull, and a salvage net is installed at the end of the rotating frame away from the side of the hull.

[0022] like Figure 2-4 As shown, in this utility model, the rotating frame includes an L-shaped rotating rod 2. A horizontal handle 3 is fixed to the upper end of the vertical rod of the rotating rod 2. The waist of the horizontal rod of the rotating rod 2 is rotatably installed on the top of the side of the boat. The free end of the horizontal rod of the rotating rod 2 is fixed to the salvage net.

[0023] like Figure 4 As shown, in order to achieve the rotation of the salvage net, two opposing fixed plates 4 are fixed on the side of the hull 1. A round shaft 5 is fixed between the two fixed plates 4 near their upper ends. A round hole is opened on the crossbar of the rotating rod 2, and the round hole is rotatably engaged with the round shaft 5.

[0024] like Figure 2-4 As shown, in this utility model, the salvage net specifically includes a U-shaped enclosure 6. The open end of the enclosure 6 faces the free end of the crossbar of the rotating rod 2. An installation strip 7 is fixed between the bottom sides of the open end and the closed end of the enclosure 6. Several equally spaced adjustable baffles 8 are installed between the tops of the two installation strips 7.

[0025] like Figure 3 As shown, in order to fix the salvage net, an ear plate 9 is fixed at the top middle position of the mounting strip 7 near the rotating rod 2, and the free end of the crossbar of the rotating rod 2 is fixed to the side of the ear plate 9.

[0026] like Figure 4 As shown, in order to adjust the spacing of the stop bar 8, a number of equally spaced screw holes are provided on the mounting strip 7 along its length. An insertion hole is provided near the end of the stop bar 8, which is vertically opposite to the screw holes. A bolt 10 is disassembled in the insertion hole, and the lower end of the bolt 10 is threaded into the screw hole.

[0027] The working principle of this utility model will be explained in detail below: After the hull 1 enters the aquaculture pond, the worker holds the horizontal handle 3 and lifts the rotating rod 2 upwards. The horizontal bar of the rotating rod 2 rotates along the circular shaft 5, which causes the closed end of the retrieval net to rotate downwards and enter the water of the aquaculture pond. Figure 5 As shown, fish enter the enclosure 6, smaller fish and excess water fall into the aquaculture pond between the two adjacent baffles 8, pressing down the horizontal handle 3, which in turn causes the closed end of the retrieval net to rotate upwards until it is tilted, as shown. Figure 6 As shown, at this time, the fish will slide down the baffle 8 by gravity and fall into the cabin of the hull 1, thus collecting the fish. If you want to sort fish of different sizes, you can unscrew the bolt 10 from the mounting strip 7 and then pull the bolt 10 off the baffle 8. This will adjust the distance between two adjacent baffles 8. Then insert the bolt 10 into the socket until the bolt 10 is screwed into the screw hole to fix the baffle 8.

[0028] The rotation of the rotating rod 2 of this utility model can also be achieved in other ways. For example, a vertical hydraulic cylinder can be installed at the bottom of the cabin of the hull 1. The piston rod of the hydraulic cylinder is upward and hinged to the horizontal handle 3. In this way, the rotation of the rotating rod 2 can be driven by the up and down movement of the piston rod of the hydraulic cylinder. Using a hydraulic cylinder makes the rotation of the rotating rod 2 more labor-saving. This method is better and can be selected according to the actual situation. Alternatively, a hydraulic cylinder can be omitted and manual operation can be used directly.

[0029] Compared with the prior art, this utility model has the following advantages: lifting the rotating rod 2 upwards allows the fishing net to be extended into the aquaculture pond to catch fish; pressing down the rotating rod 2 causes the closed end of the fishing net to tilt upwards, allowing the fish to slide directly into the cabin of the hull 1, making it more convenient to catch fish and saving the need to manually remove the fish from the fishing net and put them into the cabin.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
