Efficient capturing device for ricefield eels and crayfishes

Abstract

The invention discloses an efficient capturing device for ricefield eels and crayfishes. The device comprises a casing, a buffer slope positioned inside the casing, a central cavity adjacent to the buffer slope, a trapping box and a starting mechanism below the trapping box. Compared with the prior art, the device has the advantages of simple structure and convenience in use; during use, human care is not needed, bait is directly putted into the trapping box, and a baffle is opened; after the weight in the trapping box reaches a specific value, the trapping box descends and a steel wire rope is pulled by mutual attraction of magnets, so that the baffle descends to shield the open end, and the death of the ricefield eels and the like in the trapping box caused by excessive captured ricefield eels is prevented; the survival rate of the captured ricefield eels and crayfishes is high; proper amount of water is always kept in the trapping box through a through hole; the trapping box can sink when being held with efficient ricefield eels and crayfishes; at the moment, water content in the trapping box is also gradually increased along with the sinking of the trapping box, so that the condition that the ricefield eels and the crayfishes in the trapping box are choked to death is prevented, and the freshness is ensured. The device does not need human care and food materials in the device cannot escape; the food materials in the device only need to be taken out when being harvested on the second day; after cleaning is finished, the bait is added for next capturing work, and the captured food materials are quantitative and adequate; meanwhile, the design of the trapping box also ensures that the ricefield eels cannot escape; the capturing operation can be always performed beforethe baffle does not shield the open end.

Description

technical field [0001] The invention relates to the technical field of eel fishing, in particular to a high-efficiency catching device for eel and crayfish and a method for using it. Background technique [0002] At present, traditional fishing cages are still used to catch eels and crayfish, which are relatively slow and inefficient, and there are many problems. To effectively control the amount of capture, the fishing efficiency is not high and the artificial fishing efficiency is too slow, which requires artificial supervision, the escape problem of captured eels and crayfish, and the overall structure of the device is relatively complicated, etc., so how to It is a problem to be solved to design a convenient and practical device that can effectively store the captured food, ensure that the captured quantity is sufficient, and will not cause the death of eels and others due to overcrowding, affecting the freshness of the ingredients, and does not require manual supervisio...
