Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a shrimp trap. Background Technology

[0002] As the main stage of shrimp farming, the harvesting process currently relies primarily on traditional methods. Traditional round traps are widely used in shrimp harvesting, which includes four processes: setting the trap, lifting the trap, emptying the trap, and transferring the trap.

[0003] However, the existing traditional circular fish traps have the following drawbacks during use:

[0004] Traditional fish traps have poor rigidity and are prone to deformation during the fishing process due to uneven tension or changes in the external environment, which can lead to reduced fishing efficiency or even damage to shrimp and affect sales.

[0011] The sliding element is configured to drive the extension and retraction of the bracket assembly and the bottom support assembly. The shrimp trap has at least two working states: the trap setting state and the trap retraction state.

[0012] When the shrimp trap is in the retracted state, the sliding member moves along one of the vertical directions, and the sliding member drives the bracket assembly and the bottom support assembly to retract inward, wherein the bottom support assembly is located inside the bracket assembly;

[0013] When the shrimp trap is in the trapping state, the sliding member moves in another vertical direction, and the sliding member drives the bracket assembly and the bottom support assembly to extend outward, wherein the bottom support assembly is in a horizontal state.

[0014] Preferably, the shrimp trap also has a shrimp-collecting state. When the shrimp trap is in the trap-laying state, and the bottom support assembly is configured to be pressured at its upper end, the second end of the crossbar extends downward to form the shrimp-collecting state.

[0015] Preferably, the long support is an elastic long support.

[0016] Preferably, when the shrimp trap is in the retracted state, the first end of the short support is located above the second end of the short support, the sliding member is configured to move downward in the vertical direction to adjust the shrimp trap to the set-up state, and the sliding member is configured to move upward in the vertical direction to adjust the shrimp trap to the retracted state.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] This shrimp trap allows the sliding component to move on the fixed component. The sliding component drives the long support to extend or retract, thereby causing the short support to rotate around the fixed component. This enables the shrimp trap to switch autonomously between the trap setting state and the trap closing state. When not in use, the shrimp trap can be switched to the trap closing state to reduce the storage area of ​​the device.

[0028] The horizontal bar and shrimp-inverting ring on the bottom increase the weight of the bottom of the trap, preventing it from tipping over when it falls into the water. They also enhance the rigidity of the trap, preventing it from deforming severely when catching a large number of shrimp.

[0036] The following description is intended to provide a detailed account of the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0037] See Figure 1-5 This utility model provides a technical solution: a shrimp trap, including a sliding member 2 and a fixing member 3 arranged at relatively intervals along the vertical direction, wherein the sliding member 2 is movably connected above the fixing member 3 in a vertical direction;

[0038] The support assembly includes a long support 5 and a short support 6. The first end of the long support 5 is hinged to the outside of the sliding member 2, the first end of the short support 6 is hinged to the outside of the fixing member 3, and the second end of the short support 6 is hinged to the middle of the long support 5. The short support 6 connects the fixing member 3 and the long support 5. The short support 6 is used to improve the overall stability of the ground cage. There are multiple support assemblies, which are arranged at intervals along the circumference of the fixing member 3 and the sliding member 2.

[0039] The bottom support assembly includes a shrimp-inverted ring 8 and a crossbar 7. The shrimp-inverted rings 8 are spaced apart below the fixing member 3. The first end of the crossbar 7 is hinged to the second end of the long support 5, and the second end of the crossbar 7 is hinged to the shrimp-inverted rings 8. The crossbar 7 is used to connect the long support 5 and the shrimp-inverted rings 8 to enhance the overall strength of the trap.

[0040] The sliding member 2 is configured to drive the extension and retraction of the bracket assembly and the bottom support assembly. The shrimp trap has at least two working states: the trap setting state and the trap retraction state.

[0041] See Figure 2 When the shrimp trap is in the retracted state, the sliding member 2 moves along one of the vertical directions, and the sliding member 2 drives the bracket assembly and the bottom support assembly to retract inward, wherein the bottom support assembly is located inside the bracket assembly;

[0042] See Figure 1When the shrimp trap is in the trapping state, the sliding member 2 moves in another vertical direction, and the sliding member 2 drives the bracket assembly and the bottom support assembly to extend outward, wherein the bottom support assembly is in a horizontal state.

[0043] The sliding member 2 moves on the fixed member 3, and the sliding member 2 drives the long support 5 to extend or retract, thereby driving the short support 6 to rotate around the fixed member 3, so as to realize the autonomous switching between the shrimp trap setting state and the trap closing state. When not in use, the shrimp trap is switched to the trap closing state to reduce the storage area of ​​the device.

[0044] The horizontal bar 7 and the shrimp-inverting ring 8 located on the bottom increase the weight of the bottom of the trap, preventing the top of the trap from tipping over after it falls into the water. They also enhance the rigidity of the trap, preventing it from deforming severely when catching a large number of shrimp.

[0045] It should be noted that a locking element is provided between the sliding member 2 and the fixing member 3, so that when the shrimp trap is adjusted to the trap setting state or the trap closing state, the sliding member 2 and the fixing member 3 can be locked by the locking element, so that the shrimp trap can maintain the trap setting state or the trap closing state.

[0046] See Figure 3 The shrimp trap also has a shrimp-collecting state. When the shrimp trap is in the trap-laying state, and the bottom support assembly is configured to be pressured at its upper end, the second end of the crossbar 7 extends downward to form the shrimp-collecting state, i.e., the bottom support assembly is funnel-shaped. Adding the crossbar 7 at the bottom of the trap ensures that it does not easily deform during the hauling process and allows gravity to concentrate the shrimp at the bottom of the trap. Specifically, the bottom of the trap is funnel-shaped during hauling, which allows gravity to concentrate the shrimp to the center of the bottom, greatly improving the efficiency and quality of shrimp harvesting. It is also suitable for automated hauling operations. Specifically, the long support 5 is an elastic long support 5, and / or the crossbar 7 is an elastic crossbar 7.

[0047] In this embodiment, when the shrimp trap is in the retracted state, the first end of the short support 6 is located above the second end of the short support 6, the sliding member 2 is configured to move downward in the vertical direction to adjust the shrimp trap to the set-up state, and the sliding member 2 is configured to move upward in the vertical direction to adjust the shrimp trap to the retracted state.

[0048] A rigid sliding shaft 4, arranged vertically, is installed above the fixing member 3. The sliding member 2 is slidably connected to the outside of the sliding shaft 4. The fixing member 3 and the sliding shaft 4 are fixedly connected at the middle. A circular sliding ring 13 is provided on the outside of the sliding shaft 4. The sliding ring 13 is located below the fixing member 3 and is adapted to move along the length direction of the sliding shaft 4. A connecting rod 14 is provided between the sliding ring 13 and the inverted ring 8. One end of the connecting rod 14 is hinged to the sliding ring 13. The other end is hinged to the shrimp-inverting ring 8. By adding a sliding shaft and connecting rod inside the shrimp trap, the sliding shaft 4 is used to connect the fixing part 3 and the sliding part 2, so that the sliding part 2 can slide up and down, changing the traditional way of trapping and making trapping more convenient. Compared with the traditional round trap that uses a central rope to pull it open, which has problems such as easy wear and breakage of the rope, and difficulty in pressing the top and easy damage to the net, the sliding shaft inside the shrimp trap can replace the rope, push and pull the bottom shrimp-inverting ring 8 to achieve the purpose of trapping and opening and closing, and enhance the rigidity of the entire trap.

[0049] Both the fixing member 3 and the sliding member 2 are disc-shaped. The fixing member 3, the sliding member 2, and the inverted shrimp ring 8 are arranged in parallel intervals. The long brackets 5 are arranged at intervals along the outer periphery of the sliding member 2, and the short brackets 6 are arranged at intervals along the outer periphery of the fixing member 3. The crossbars 7 correspond one-to-one with the long brackets 5. The crossbars 7 are arranged at intervals along the circumference of the inverted shrimp ring 8. Preferably, the distance between adjacent long brackets 5 is equal, the distance between adjacent short brackets 6 is equal, and the distance between adjacent crossbars 7 is equal.

[0050] In one embodiment, the locking element is disposed between the sliding shaft 4 and the sliding element 2. There are two locking elements, which correspond to the positions of the sliding element 2 on the sliding shaft 4 when the shrimp trap is in the cage-setting state and the positions of the sliding element 2 on the sliding shaft 4 when the shrimp trap is in the cage-closing state. Optionally, the locking element is a buckle.

[0051] In the use of traditional circular fish traps, lifting is achieved via a cable at one end. The connection method is relatively simple, the load-bearing capacity of the connection points is limited, and it is difficult to meet the requirements of other automated fishing equipment, resulting in poor compatibility. To solve these problems, further... (See...) Figure 1-3The top end of the sliding shaft 4 is provided with a connector 1 that can be detachably engaged with the external gripping mechanism. In one embodiment of this utility model, the connector 1 is a circular magnet. The magnet and the sliding shaft 4 are attracted together. By expanding the top space of the fish trap, it can be used for permanent magnet or electromagnet attraction. It can simultaneously meet the requirements of traditional fishing operations and be compatible with automated fishing equipment. Specifically, the fish trap can be lifted and transported by electromagnetic attraction. By setting a platform on the top of the fish trap, the contact area can be increased to facilitate magnet attraction.

[0052] See also Figure 4 and 5 To enhance the strength of the device, the first end of the short bracket 6 is provided with a triangular short protrusion 12, the short protrusion 12 having a circular hole, and the short bracket 6 is hinged to the outside of the fixing member 3 through the short protrusion 12.

[0053] The long support 5 has a triangular protrusion 11 in the middle, and the protrusion 11 has a circular hole. The long support 5 is hinged to the second end of the short support 6 through the protrusion 11.

[0054] The crossbar 7 has circular holes at both ends. The first end of the crossbar 7 and the second end of the long support 5, as well as the second end of the crossbar 7 and the inverted shrimp ring 8, are hinged.

[0055] Furthermore, the shrimp-inverted ring 8 and the fixing member 3 are arranged in parallel and spaced apart. The bottom of the shrimp-inverted ring 8 is provided with a shrimp-inverted protrusion. The shrimp-inverted protrusion is rectangular, preferably rectangular. The shrimp-inverted protrusion has a circular hole. The shrimp-inverted ring 8 is hinged to the second end of the crossbar 7 through the shrimp-inverted protrusion.

[0056] See Figure 6 The shrimp trap also includes:

[0057] A cage net 9 is installed outside the support assembly and the bottom support assembly, forming a shrimp-catching area. The cage net 9 has an outlet and an inlet 10 that communicate with the shrimp-catching area. The outlet corresponds to the shrimp-catching ring 8. There are multiple inlets 10, which are distributed outside the cage net 9 to avoid the support assembly. The radial cross-sectional dimension of the inlet 10 gradually decreases as it approaches the shrimp-catching area, that is, the inlet 10 is a funnel-shaped inlet 10.

[0058] How to use:

[0059] See Figure 1 and 2By lifting the sliding shaft 4, the sliding part 2 and the sliding shaft 4 slide relative to each other. At this time, the long bracket 5 hinged on the sliding part 2 retracts inward, the short bracket 6 hinged on the fixed part 3 retracts inward and stands upright, and the horizontal bar 7 at the bottom retracts upward, causing the circular shrimp ring 8 to move upward, thereby adjusting the shrimp trap to the trap-closing state.

[0060] When switching the shrimp trap to the net trap state, pressing the sliding shaft 4 causes the sliding member 2 to slide relative to the sliding shaft 4. At this time, the long support 5 hinged on the sliding member 2 extends outward. Due to the elasticity of the long support 5, it bends from an upright state. The short support 6 hinged on the fixing member 3 extends outward from an upright state. At the same time, the circular shrimp-inverting ring 8 moves downward, and the bottom crossbar 7 extends downward from an upright state. The circular shrimp-inverting ring 8 moves downward until it touches the bottom of the pond and becomes horizontal. For the trap inversion process, see... Figure 3 The bottom horizontal bar 7 extends downwards from a horizontal position to a funnel shape, using gravity to slowly gather the shrimp to the center, and then using gravity to pour the shrimp out.

[0061] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
