Description

Technical Field

[0001] The utility model belongs to the technical field of breeding devices, and in particular relates to a breeding device for shrimps. Background Art

[0002] Shrimp farming is an aquaculture industry with high economic value. Farming methods include pond farming, harbor farming, cage farming, etc., and sometimes mixed farming methods such as fish, shrimp, and shellfish are also adopted. The main species farmed are marine shrimps such as Penaeus orientalis and Penaeus monodon, and freshwater shrimps such as Macrobrachium rosenbergii. The main links of shrimp farming include seedling cultivation and growout. In the seedling cultivation stage, shrimp seedlings can be directly caught from natural breeding grounds or brought in by tidal water, or they can be cultivated through artificial breeding. There are many types of seedling cultivation facilities, including earth ponds, cages, cement pools, and polyester tanks, with cement pools and polyester tanks being the main ones. In the growout stage, shrimp seedlings need to gradually adapt to the temperature and water quality of the aquaculture water before being put into the pond.

[0003] During the molting period or the breeding period, shrimps are easily preyed on by other species, resulting in a reduced box output rate. Therefore, a shrimp breeding device is provided to prevent the above situation from occurring. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a shrimp breeding device.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A shrimp farming device comprises a cage frame, wherein the four lower corners of the cage frame are connected to a capture net via diagonal braces;

[0007] A plurality of spiral protective felts are arranged inside the cage frame, wherein the spiral protective felts include two spirally interwoven felts, and a gap of 1-3 mm is formed between the felts of the spiral protective felts for shrimps to crawl through;

[0008] The cage frame is provided with a fixed cross bar at a position corresponding to the spiral protective felt, and the fixed cross bar is provided with habitat pieces at intervals along the length direction;

[0009] The bottom of the capture net is connected to a net bag, and an opening is arranged at the lower end of the net bag. During breeding, the opening is tied tightly, and during unloading of shrimps, the opening is opened.

[0010] It is further defined that the four upper corners of the cage frame are connected with lifting rings, and such a structural design allows the lifting rings to provide lifting points during lifting.

[0011] It is further defined that the mesh size of the capture net and the net bag is 2-3 cm. With such a structural design, small-sized shrimps will fall from the mesh size back into the breeding pond, and the finished shrimps will gather in the net bag in the middle.

[0012] It is further defined that an anti-escape opening is provided at the junction of the capture net and the net bag, and the anti-escape opening has two states: an open state and an open state. With such a structural design, when the anti-escape opening is closed, the finished shrimps can be prevented from entering the net bag, and when the anti-escape opening is opened, the finished shrimps can enter the net bag through the anti-escape opening.

[0013] It is further defined that the opening at the lower end of the net bag cooperates with a rope, and the rope realizes the tightening or opening of the opening. With such a structural design, the rope closes the opening at the lower end of the net bag by its own binding, or opens the opening at the lower end of the net bag by its own unlocking.

[0014] The beneficial effects of the utility model are as follows: the utility model is placed in a breeding pond to provide a refuge and habitat for shrimps, thereby solving the problem that shrimps are easily preyed upon during molting or breeding. The utility model can also be used as a capture facility, and after being directly lifted out of the water, the shrimps in the breeding device can be shaken off into a capture net bag, thereby facilitating the capture and sale of the shrimps.

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-2 As shown, a shrimp farming device of the utility model comprises a cage frame 1, and a capture net 6 is connected to the four lower corners of the cage frame 1 through diagonal braces 2;

[0031] A plurality of spiral protective felts 3 are arranged inside the cage frame 1. The spiral protective felts 3 include two spirally interwoven felts. A gap of 1-3 mm is formed between the felts of the spiral protective felts 3 for shrimps to crawl through.

[0032] The cage frame 1 is provided with a fixed cross bar 4 at a position corresponding to the spiral protective felt 3, and the fixed cross bar 4 is provided with habitat pieces 5 at intervals along the length direction;

[0033] The bottom of the capture net 6 is connected to a net bag 7, and an opening 8 is arranged at the lower end of the net bag 7. When the shrimps are cultured, the opening 8 is tied tightly, and when the shrimps are unloaded, the opening 8 is opened.

[0034] In this embodiment:

[0035] The spiral protective felt 3 includes two spirally interwoven felts, and a gap of 1-3 mm is formed between the felts for shrimps to crawl freely. The shrimps can move along the felts to reach the habitat pieces 5 at different positions on the fixed crossbar 4. The habitat pieces 5 are in the gap between the felts, and with the help of the felt hair protection, a safe habitat platform is provided for the shrimps.

[0036] When it is necessary to catch and sell, the cage frame 1 is directly lifted off the water surface, and the shrimps on the habitat sheets 5 are shaken to fall into the capture net 6 below. The finished shrimps will gather in the net bag 7 at the bottom of the capture net 6. The opening 8 at the lower end of the net bag 7 is opened to form a falling channel, and the finished shrimps can be obtained in batches.

[0037] Preferably, the four upper corners of the cage frame 1 are connected with lifting rings 10. With such a structural design, the lifting rings 10 are used to provide lifting points during lifting. In fact, other lifting structures can also be considered according to specific circumstances.

[0038] Preferably, the mesh of the capture net 6 and the net bag 7 is 2-3 cm. With this structural design, small shrimps will fall from the mesh back into the breeding pond, and the finished shrimps will gather in the middle net bag 7. In fact, other screening criteria for the capture net 6 and the net bag 7 can also be considered according to specific circumstances.

[0039] Preferably, an anti-escape opening 9 is provided at the connection between the capture net 6 and the net bag 7, and the anti-escape opening 9 has two states: an open state and an open state. With such a structural design, when the anti-escape opening 9 is closed, the finished shrimps can be prevented from entering the net bag 7, and when the anti-escape opening 9 is opened, the finished shrimps can enter the net bag 7 through the anti-escape opening 9. In fact, other anti-escape structures between the capture net 6 and the net bag 7 can also be considered according to specific circumstances.

[0040] Preferably, the opening 8 at the lower end of the net bag 7 cooperates with the rope, and the rope realizes the tightening or opening of the opening 8. With this structural design, the rope closes the opening 8 at the lower end of the net bag 7 by its own binding, or opens the opening 8 at the lower end of the net bag 7 by its own unlocking. In fact, other structural shapes for controlling the state of the opening 8 at the lower end of the net bag 7 can also be considered according to specific circumstances.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
