Description

Technical Field

[0001] This utility model relates to the field of products related to lobster farming, specifically a lobster catching device. Background Technology

[0002] Crayfish are freshwater economic shrimp species, widely popular for their delicious meat. Their omnivorous nature, rapid growth, and strong adaptability give them a significant competitive advantage in their local ecosystems. Their diet includes aquatic plants, algae, aquatic insects, and animal carcasses. In recent years, crayfish have become an important aquaculture species in China. Once mature, crayfish need to be caught.

[0003] Existing methods for catching lobsters generally use integrated nylon nets, but setting up the nets is troublesome and catching them is inconvenient. Furthermore, the top cover of the existing net cages is difficult to install and remove, making each operation cumbersome and thus defective. Utility Model Content

[0004] The purpose of this invention is to provide a catching device for lobster farming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lobster farming catching device, comprising a net cage, catching buckets fixedly inserted on all four sides of the top of the net cage, a feeding port at the bottom of the net cage, a bottom plate inside the feeding port, one end of the bottom plate being rotatably connected to the feeding port via a pivot pin, a positioning block fixedly connected to the bottom of the other end of the bottom plate, a support block fixedly connected to the bottom of one end of the net cage, a stop rod slidably inserted on the support block, a stop groove corresponding to the stop rod on the positioning block, a trapezoidal groove at the top of the net cage, a cover plate inside the trapezoidal groove, a strip groove at the top of the cover plate, an insertion rod fixedly connected to the top of the net cage corresponding to the position of the strip groove, the insertion rod being slidably inserted into the strip groove, a slot on the insertion rod, a connecting rod slidably inserted into the slot, a butterfly-shaped limiting block rotatably connected to the top of the connecting rod, and a first stainless steel spring fixedly connected to the connecting rod and the slot.

[0006] As a preferred embodiment of this utility model, one end of the stop rod is fixedly connected to an anti-detachment block, and a second stainless steel spring is sleeved on the stop rod, with the two ends of the second stainless steel spring abutting against the anti-detachment block and the support block, respectively.

[0007] As a preferred embodiment of this utility model, a float plate is provided above the net cage, and the bottom end of the float plate is fixedly connected to the net cage by a traction rope.

[0008] As a preferred embodiment of this invention, a sealing ring is fixedly fitted onto the insertion rod.

[0009] As a preferred embodiment of this invention, the net cage is provided with a bait net box, which is fixedly connected to the cover plate by a connecting rope.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This lobster farming catching device captures lobsters through the catching bucket on the net cage. The strip groove on the cover plate corresponds to the position of the butterfly-shaped limiting block, allowing the cover plate to pass through the butterfly-shaped limiting block. Then, pulling the butterfly-shaped limiting block causes the connecting rod to move inside the insertion rod, thereby stretching the first stainless steel spring. Then, rotating the butterfly-shaped limiting block causes the butterfly-shaped limiting block to be misaligned with the strip groove. Finally, the first stainless steel spring causes the butterfly-shaped limiting block to press against the cover plate to achieve its installation and fixation.

[0012] This lobster farming catching device allows lobsters to be fed by pulling the stop rod out of the stop groove on the positioning block and rotating the bottom plate around the pivot pin to open the net cage.

[0013] This lobster farming catching device facilitates the assembly and disassembly of the net cages through snap-fit ​​fixing components. The net cages do not require external binding and make it easy to feed and catch lobsters. Attached Figure Description

The cover plate 8 passes through the butterfly-shaped limiting block 11. Then, the butterfly-shaped limiting block 11 is pulled to cause the connecting rod 10 to move in the insertion rod 9, thereby stretching the first stainless steel spring 12. Then, the butterfly-shaped limiting block 11 is rotated to make the butterfly-shaped limiting block 11 and the strip groove misaligned. Then, the first stainless steel spring 12 causes the butterfly-shaped limiting block 11 to press against the cover plate 8 to achieve its installation and fixation. By pulling the stop rod 7 out of the stop groove on the positioning block 5, the bottom plate 3 is rotated around the shaft pin 4, thereby opening the net cage 1 to allow the lobsters to be fed.
