Technical Field

[0001] The present invention relates to the technical field of fishing devices, and in particular to a shrimp and crab fishing device suitable for an automated system. Background Art

[0002] Currently, the fishing device for crayfish and river crabs is a ground cage. The ground cage is usually made of a metal frame and a plastic fiber mesh (square or round). There are many entrances on both sides of the ground cage. The entrances are trumpet-shaped inverted mesh openings (crayfish and river crabs can only enter but not exit). The two ends of the ground cage net are conical fishing net bags. When river crabs and crayfish enter the ground cage through the entrance, they crawl into the fishing net bags at both ends in the one-way net cage and are caught. Ground cages are suitable for various breeding environments, but there are a series of problems and disadvantages in the use of ground cages:

[0003] 1) The operation is time-consuming and labor-intensive: In the fishing of river crabs and crayfish, 3-4 ground cages (about 10 meters) are required per acre of pond, and 300-400 ground cages are required for a 100-acre breeding pond. The fishing workload is huge, the time-consuming, and the whole process requires a lot of labor; 2) The models and specifications are not targeted: The ground cages on the market are usually universal ground cages, and their working scenes are suitable for various aquatic animals, including fish, shrimp, crabs, etc., but they have no advantages in fishing a single species; 3) High labor costs: The current fishing of crayfish and river crabs still relies mainly on manpower, and the automation penetration rate is low. A lot of labor costs are consumed in the ground cage fishing work. Therefore, it is urgent to design a shrimp and crab fishing device suitable for an automated system to solve the above problems.

A buckle 9 is provided at the connection between the lifting rope 8 and the collection cage 1. The collection cage 1 is sleeved in the frame 21 and is magnetically connected to the bidirectional magnetic interface 5 through the collection cage magnetic interface 4. The buckle 9 can be mutually engaged with the frame 21. Specifically, the buckle 9 is a structure with a traction hole in the middle and a diameter of 1 cm. The buckle 9 extends outward from the edge of the collection cage 1 by 0.1m, so that when the collecting net cage 1 is put into the frame 21, the buckle 9 can be clamped on the frame 21, and when the buckle 9 is clamped on the frame 21, the collecting net cage magnetic interface 4 is aligned with the two-way magnetic interface 5 and the pulling rope 8 cooperates with the external traction and lifting device.

The magnetic force between the fishing net magnetic interface 6 and the two-way magnetic interface 5 is 100N, ensuring that the fishing net 3 will not separate from the cage frame 2 under normal weather conditions. The magnetic force between the collection net magnetic interface 4 and the two-way magnetic interface 5 is 40N, ensuring that the collection net 1 will not separate from the cage frame 2 under normal weather conditions. When the collection net 1 needs to be separated from the cage frame 2, it can be lifted from the frame 21 with relatively little effort.

[0037] Combined with attachment Figure 1 、 3, 5, 9, and 11, the mesh cage frame 2 is detachably connected to the base 7, and the mesh cage frame 2 also includes an insertion rod 23 installed at the bottom of the frame 21, wherein the insertion cylinder 23 is 30 cm long, and a latch 24 is provided on the insertion rod 23.

The frame 21 is provided with a spirit level 26. Since the base 7 is provided, the base 7 is preferably placed at the bottom of the fishing pond. Then the net cage frame 2 is installed on the base 7 through the pin 24 and the bayonet 73 on the stainless steel tube 72 of the base 7. Since several bayonet holes 73 are provided, in conjunction with the spirit level 26, the horizontal degree of the net cage frame 2 is adjusted so that the net cage frame 2 is in a horizontal state, so that the collection net cage 1 can be put into the frame 21 or removed from the frame 21 when moving up and down.

[0038] Combined with attachment Figure 1-4 As shown, a lead block 14 is provided at the bottom of the bottom foldable net cage 13, and an inclined smooth baffle 25 is provided at the top of the frame 21 to guide the collecting net cage 1 when the collecting net cage 1 is inserted into the frame 21, wherein the angle between the inclined smooth baffle 25 installed on the frame 21 and the plane where the top of the frame 21 is located is 60°, and the distance between the edge of the inclined smooth baffle 25 and the frame 21 is 30 cm. The material of the inclined smooth baffle 25 is PVC. By setting the lead block 14, under the action of gravity, the collecting net cage 1 can move downward after entering the fishing pond. Due to the setting of the inclined smooth baffle 25, when the collecting net cage 1 falls close to the net cage frame 2, under the guidance of the inclined smooth baffle 25, the position and deflection angle of the collecting net cage 1 can be guided, so that the collecting net cage 1 can be better inserted into the frame 21.

After the shrimp and crab collection is completed, the collection cage 1 is moved out of the fishing pond under the action of an external traction and lifting device, and the unloading port cover 101 is removed so that the shrimp and crabs can be taken out of the collection cage 1 through the unloading port 10.

[0040] Working principle: When preparing for fishing, first place the base 7 on the bottom of the fishing pond, then install the net cage frame 2 on the base 7, and adjust the horizontal degree of the frame 21 according to the indication of the spirit level 26 so that the frame 21 is in a horizontal state, and then select the corresponding number of fishing net cages 3 according to the actual fishing needs, and magnetically connect the fishing net cage 3 with the two-way magnetic interface 5 through the fishing net cage magnetic interface 6 to complete the installation of the fishing net cage 3, and install the unloading port cover 101 on the unloading port 10. When fishing, put the attractant in the fishing net cage 3, and lift the collecting net cage 1 through the external traction and lifting device, and make the collecting net cage 1 above the net cage frame 2, and then the collecting net cage 1 gradually moves downward. Under the action of the lead block 14, the collecting net cage 1 approaches the frame 21, and then under the guidance of the inclined smooth baffle 25, the collecting net cage 1 is sleeved in the frame 21, and then as the collecting net cage 1 continues to move downward, the buckle 9 is snapped into place. On the frame 21, the two-way magnetic interface 5 is magnetically connected to the collection net cage magnetic interface 4, the fishing net cage 3, the two-way magnetic interface 5, the collection net cage inverted mouth 41 and the collection net cage 1 are connected to each other, and then the attractant attracts shrimps and crabs, and the shrimps and crabs enter the fishing net cage 3 through the inverted shrimp attractant hole on the fishing net cage 3. Under the action of the one-way corridor of the fishing net cage 3, the shrimps and crabs enter the collection net cage 1. When the shrimps and crabs in the collection net cage 1 need to be taken out, the external traction and lifting device will collect them. The net cage 1 is lifted upward and lifted away from the fishing pond, and then the collection net cage 1 containing shrimps and crabs can be transferred to a subsequent area. With the help of another external traction and lifting device, the collection net cage 1 without shrimps and crabs is lifted back above the net cage frame 2. The external traction and lifting device can be installed on a circulating line to form an assembly line to complete various processes such as shrimp and crab fishing, collection, transfer and transportation. After the fishing season ends, the base 7, fishing net cage 3 and net cage frame 2 can be taken out of the fishing pond.
