Crab-culture pond crab trapping device

Abstract

The invention relates to a crab-culture pond crab trapping device. According to the invention, a crab feeding station is enclosed by net walls on three sides, and is open on one side. A sliding door is arranged on a net wall on the crab feeding station. A sliding door string is connected to each of the two ends of the sliding door. The sliding door can be opened and closed in a sliding way with the cooperation of the sliding door strings. A crab collection cage is connected to the back of the crab feeding station. A crab inlet is arranged on the net wall on the back of the crab collection cage. A passage guiding net is connected to the two sides of the crab inlet and the net wall. The passage guiding net is a narrow passage connected to a crab fetching cage. A cage lifting ring is connected to the crab fetching cage. Inverted steel whiskers and a connection hook are arranged on the crab fetching cage on the back end of the passage guiding net. With the connection hook, the crab fetching cage can be detached or attached. Internal inverted whiskers are arranged on the crab inlet. The internal inverted whiskers extend inward, and are connected with an internal inverted whisker port. The internal inverted whisker port is fixed with internal inverted whisker port drawstrings. The crab feeding station, the crab collection cage and the sliding door are fixed and connected through the net walls, upper and lower ropes and setting piles.

Description

technical field [0001] The invention relates to a crab trapping device, in particular to a crab trapping device in a crab breeding pond, and belongs to the technical field of crab trapping devices. Background technique [0002] At present, when people catch crabs in crab ponds, they generally use bamboo crab cages for fishing. However, due to the short service life and easy fragmentation of bamboo cages, it is easy for crabs entering the cage to escape from the fragments. Therefore, the existing bamboo crab cages have the defects of complex weaving process, short service life, easy fragments, easy escape of crabs, few crab catches and poor crab catch effect in crab ponds for crab cultivation. Contents of the invention [0003] The object of the present invention is to provide a kind of device for trapping crabs in a crab pond with simple structure, long service life, durability, difficulty in escaping crabs, large amount of crabs and good crab catching effect, which can ov...
