Crayfish catching device for rice field planting and breeding system

Abstract

The invention provides a crayfish catching device for a rice field planting and breeding system. The crayfish catching device comprises a folding box, a supporting frame which is accommodated in the folding box and can be unfolded and a surrounding net which is used for wrapping the periphery of the supporting frame, wherein the folding box comprises a bottom box body and a top box body which is hinged with the bottom box body, the bottom box body and the top box body can be folded or unfolded, and bait placers are arranged on the bottom surfaces of the bottom box body and the top box body. According to the crayfish catching device, when the crayfish catching device is not used, all parts are stored by the folding box, the folding box is convenient to carry, when the crayfish catching device needs to be used, rapid assembly can be achieved, and the convenience in crayfish catching is improved; and the crayfish can only enter the device but cannot exit from the device by means of a trapping door, the crayfish catching amount is increased, compared with a ground cage, the crayfish catching device is heavier and can quickly reach the water bottom, crayfish catching operation can be achieved without other procedures, and the labor intensity of operators is greatly relieved.

Description

technical field [0001] The invention relates to a shrimp catching device, more specifically to a crayfish catching device used in a paddy field cultivation system.

Problems solved by technology

At present, paddy field farming of crayfish has become a trend. At present, the crayfish farmed in paddy fields are caught in the form of ground cages or artificial nets. The manual netting method is not efficient and labor-intensive, and the weight of the ground cage is not enough. , the ground cage is difficult to directly contact the mud bottom, resulting in a small number of crayfish caught, and more ground cages need to be placed to meet the requirements, so it brings a lot of unnecessary troubles to people
